Recently, the reporter learned from the Municipal Bureau of Agricultural Machinery that due to the traditional method of drying grain on the ground and other foodstuffs, it is easy to cause high food loss, degraded quality, and difficulty in storage. In today's world, the food grain has increased in 12 consecutive days, and grain has been developed. Drying mechanization is imminent. By the end of the year, the city plans to establish 5 grain drying mechanization demonstration zones, 5 large-scale grain drying service centers, and grain drying machines to 30 units. The daily grain drying capacity will reach over 900 tons.
It is reported that grain drying machinery and equipment will be used as the focus of purchase subsidies for agricultural machinery, so that it can be purchased and supplemented, and subsidies should be made. The relevant project funds will be used preferentially for grain drying operations and actively strive for the land required for grain drying and construction. Priority protection. The city will also increase the demonstration and promotion efforts. Qihe, Luancheng, Linyi, Lingxian and other large grain-producing counties shall establish demonstration areas for grain drying mechanization and encourage strong agricultural cooperatives to develop grain drying equipment and lead the city to the whole city. Grain drying mechanization development.
In order to develop grain dryers, agricultural machinery manufacturers have stepped up their cooperation to provide free training for grain drying operators and to improve the operation and use of grain drying technology as soon as possible. By the end of the year, the city has established 5 grain drying mechanization demonstration areas, 5 large-scale grain drying service centers, and grain drying machines have been developed to 30 units. The grain drying capacity will reach 900 tons or more.
Hoisting Mechanism And Spare Parts
The hoisting mechanism for a Tower Crane typically consists of a combination of a motor, a gearbox, wire ropes, and a hook block. Here is a breakdown of its components and how they work together:
1. Motor: The hoisting motor provides the power needed to lift and lower loads. It is usually an electric motor that generates high torque to handle heavy loads.
2. Gearbox: The motor's rotational motion is transmitted to the hoisting drum through a gearbox. The gearbox helps increase the torque and reduce the speed of the motor, enabling the crane to lift heavy loads at a controlled speed.
3. Hoisting Drum: The hoisting drum is a cylindrical drum around which the wire ropes are wound. It is directly connected to the gearbox and rotates as the motor operates. The drum's size and design determine the amount of Wire Rope it can hold.
4. Wire Ropes:
The wire ropes are wound around the hoisting drum and connected to the hook block. These ropes are made of high-strength steel and have a high load-bearing capacity. Multiple wire ropes are used to distribute the load evenly and ensure stability during lifting operations.
5. Hook Block: The hook block is attached to the lower end of the wire ropes and is responsible for carrying the load. It consists of a pulley system with one or more sheaves, which allows the wire ropes to change direction and support the load securely.
During operation, the motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the crane to lift or lower loads.
The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.
