Road sweeper related knowledge summary

First, what is a road sweeper

Equipped with garbage, dust collecting containers and cleaning systems, used for cleaning, collecting garbage and other contaminants in special structures.

Second, the classification of road sweeper

1. According to the way of walking, it can be divided into: push-type, walk-behind, self-style;

Hand-push sweeper: The hand-push sweeper is a small sweeper. During the cleaning operation, the operator pushes the sweeper vehicle forward behind the sweeper. The sweeping width of such road vehicles is generally between 800-1200mm, and most of them are below 1000mm. The average sweep speed is generally 3km/h, and the maximum sweep speed is generally Skm/h. Due to the manual labor of the hand-push sweeper, the operator is only suitable for the sweeping of road leveling areas such as interiors and squares.

Walk-behind sweeper: Walk-behind sweeper is a hand-push sweeper that installs a travel drive so that the operator does not need to push the sweeper when cleaning. Just walk behind the sweeper Road car. Therefore, when the walk-in sweeper is operated, the operator's labor intensity is lower than that of the hand-push sweeper. The scope of application also extends to slightly graded outdoor roads on the basis of hand-guided sweepers.

Self-propelled sweeper: The self-propelled sweeper has a complete set of travel drive and control system. The operator rides on the sweeper to control the sweeper. There are many specifications for self-propelled sweeping vehicles, sweeping widths from 1.2m to several meters, and a variety of structural types. However, self-propelled sweeping vehicles are composed of two parts: the chassis and the operating device. Most self-propelled sweepers have

There is a cab, only a small number of small self-propelled sweepers do not have a cab.

2. According to the sweeping operation mode, it is divided into three categories: pure sweep sweeper, pure suction sweeper sweeper, suction sweeper sweeper sweeper;

Pure sweeping sweeper : Pure sweeping sweeper does not have a fan installed on the sweeper. The sweeping operation sweeps the roadside trash to the sweeper under the side sweeper, and then sweeps or sweeps the material. Sweep the trash. As early as in the early 1980s, China developed a pure sweeper vehicle and used it in the sanitation department of some big cities. Later, with the development and development of the suction sweeper, pure sweeping sweeping The car was gradually replaced by a suction sweeper. The pure sweeper sweeper only sweeps (scatters) people's bins by mechanical sweeping, so no wet dusting or dry dusting is needed. In order to prevent the road sweeper from dusting during sweeping operations, spray sweepers are generally installed at the sweeping positions of the sweeper sweeper.

Suction sweeper : The sweeper is the most popular sweeper in the world. The suction sweeper is not only dry and wet, but also has a variety of structural types. Since the end of the 1980s, the Changsha Institute of Construction Machinery of the Ministry of Construction has developed China's first suction sweeper. The sweeper sweeper has developed rapidly in China. At present, most of the road sweepers produced and used in China belong to the suction sweeper.

The suction sweeper is not only equipped with a sweeping sweeper to increase sweeping width, but also has a fan. The sweeping device sweeps the trash on the side of the road to the suction nozzle, and then the fan sucks the garbage under the suction nozzle into the dust box through the air duct.

Pure suction sweeper : So far, there are few pure sweeper sweepers in road sweeping operations, but pure sweeper sweepers do exist as a type of sweeper.

3, divided by dust, can be divided into dry, wet

Dry sweeper : dry sweeper adopts dry dust removal method, that is, the sweeper does not spray water during the dust removal process. Therefore, the dry sweeper must be installed in the dustbin or the air duct. Device. When a dry sweeper sweeps, a large amount of waste that is inhaled from the mouthpiece enters the waste container, and the drastic decrease in wind speed in the waste box causes the natural sedimentation, and the inhaled light-weight fine dust passes through the air flow. The filter is trapped by the filter. Depending on the type of filter used in the sweeper, some dry sweepers can use water jet dust to counter sweep, while some dry sweepers cannot use water jet dust to prevent the filter from plugging.

Because the dry sweeper truck does not use water during dust removal, there is no phenomenon that the sweeping water is frozen because the ambient temperature is too low. Therefore, the dry sweeper truck is particularly suitable for use in water-scarce areas or areas with long cold periods.

Wet sweeper : Wet sweeper adopts wet dust removal method, that is, the sweeper sweeps the water at the suction nozzle and the suction pipe in addition to the dust at the sweeping position during the sweeping operation. The purpose of spraying the dust at the sweeping point is to make the sweeping vehicle not dust when the sweeping operation is performed, and spray dust at the suction nozzle and the suction pipe so as to make the fine dust sucked through the suction nozzle in the water mist. Wet, agglomerate into larger volumes of particles for settling in the bin.

Since dust collected by a wet sweeper coalesces after being agglomerated by water jets and can be naturally settled in the waste bin without using other measures, its air duct structure is relatively simple and no dust filter is required.

Third, the development of China's road sweeper

In the 1960s, our country developed and produced the first generation of sweepers and sweeping sweepers. Since then, it has unveiled the prelude to the development of road sweepers in China. Due to poor sweeping results, labor intensity, and inconvenient operation, it was launched. It will be eliminated soon.

In the 1970s, related research institutions and manufacturers in China increased the research and development of sweepers and the second-generation sweepers in China were born. Beijing and Shanghai have developed large-, medium-, and small-size pure sweep sweepers, and S31 large sweepers, S32 medium sweepers, and S15 small sweepers have been put into use. The dry pure suction type sweeper developed by Tianjin was put into use in small quantities. The technical level of the second generation of sweepers has been greatly improved over the first generation. However, due to the problems of low sweeping efficiency (cleaning degree) and reliability of the dry pure suction dust removal system, the use of such sweepers is greatly limited.

Fifth, the purchase of sweeping vehicles

1. The elimination system of the road sweeper consists of a main brush, a side brush and a dustbin. The side brush is required to receive a dense high-grade material and is equipped with a spring. This can effectively withstand the blow and further cover the brush wheel. .

2. Suction system: It is necessary to equip a high-powered fan so that the gas can be completely sucked into the housing filter dust collector. Such a filter container constantly shakes and oscillates during events, making it impossible to create signs of obstruction, such as jamming.

3. Garbage Dumping System: Dumping garbage from the road sweeper is accomplished through the control panel. Before dumping, the lid of the rubbish bin is closed, the control rod pulls forward, lifts the bin upside down, and when the rubbish bin is down, the control rod pushes forward to the same position.

4. The power system of the garbage sweeper is divided into diesel/gasoline, liquid propane gas, and Battery. The drive system of the road sweeper is selected according to the nature of the site, the size of the area, the type of waste, the length of operation, etc., to meet the clean demand of different customers. The use of the diesel/gasoline drive model depends on the necessary clean environment and the type of waste. As a general rule, there is a large amount of waste, and a large area with low noise and environmental requirements is clean outdoors. Choose diesel/petrol type.

5, eliminate the process necessary to sprinkle water to suppress dust, so, the size of the tank directly determines the length of continuous operation: the tank is too large, in addition to occupying the entire vehicle space, the growth of the box layout is beautiful, but also relatively reduce the space for waste settlement, impact Settlement results and the amount of garbage network; the water tank is too small, the number of renewal in the middle of the road increases, and the efficiency of the sinking is low. The suction sweeping road sweeper includes a water tank, a drain valve, a water injection port, a water pump, a spray head, and a solenoid valve. While increasing manufacturing costs, it also increased the rate of impediment.

Sixth, sweeping vehicle maintenance

1. In order to avoid mistakes, the sweeper control valve is mainly divided into the main valve and the secondary valve. Then where is the main difference between these two valves? The power of the main valve comes from the scanning board, and the power of the secondary valve comes from the auxiliary engine of the dedicated function part. Common road sweeper deputy engines include Chaochai, Jiangling and Cummins. The main valve manages the tilting of the shell behind the chassis and the hydraulic switch on the rear door of the compartment. The secondary valve manages the operation of the four floor brushes (which can individually control one side or all of the work) and the suction cup of the sweeper.

2. The secondary engine of the road sweeper is different from the power of the engine brand. However, the general speed is about 1500 to 1800 rpm.

3, according to the needs of the work can generally choose whether to bring the function of water spray dust, conventional configuration generally comes with the post-spray, at the same time need to pay attention to the clean water tank is enough water, the general clean water tank capacity is different, there may be a gap in working time.

4. The pressure adjustment of the electromagnetic multi-way valve of the road sweeper is generally on the overflow valve. The user can adjust the pressure appropriately to change the speed of the sweep brush.

5. In addition, the sweeping vehicle can select whether the left side brush and the right side brush of the vehicle work at the same time according to the road conditions. For example, if the sweeping side corner is only used to open the corner, the side brush will rotate and work.

6. There may be fine dust deposits in the dust bin of the sweeper truck, and manual manual disposal is required to clean the waste bin.

7. The distance between the suction cup of the sweeping vehicle and the ground should be adjusted frequently according to the conditions of the road section.

8, sweeping vehicles vacuum tube may often have dust and mud adhesion, need to be cleaned regularly to achieve better results.

9, the electrical parts of the control box need to be replaced in order to use a more stable, it is best to remove one for one.

10, sanitation workers should regularly check whether the functional parts are normal

11, in order to avoid foreign matter in the hydraulic oil will affect the normal operation of the electromagnetic control valve, sanitation workers should regularly check the hydraulic oil is normal.

12. Check whether the limit device of the clutch electric push rod of the secondary engine of the vehicle is normal.

13. When the control button of the sweeping vehicle is changed, the time interval should be 5 seconds

14. When a hydraulic component of a road sweeper is not working properly, check the circuit first and then check the circuit.

(1) The possible causes of the abnormal circuit part are: disconnection of insurance, loose connection of circuit, broken line

(2) The possible causes of the abnormal oil line may include: failure of the oil pump, rupture of the oil pipe, or oil leakage at the oil line connection, or malfunction of the solenoid valve.
