[0006] The principle and beneficial effects of the utility model are as follows: the granular material is transported by the belt, when the material reaches the waist roller, the waist roller is lifted to lift the belt, the belt lifts the material to scatter from the middle to both sides, and finally slides out of the chute, and the height of lifting is required to be the same as the amount of discharging, so as to achieve the purpose of ration discharging; the scheme provides a belt discharging device for multiple point discharging of the powder and large block material in the single belt transportation process, the device is simple in structure, low in use cost, convenient for taking the required amount in the operation process, easy to maintain daily, and reduces the working strength of the staff.

[0007] Scheme two, this is the preferred basis of the scheme, the waist roll is concentric shaft, waist roll both sides are connected with electric hydraulic cylinder, electric hydraulic cylinder and main frame fixed connection, waist roll is equipped with wear-resistant layer. Through the electric hydraulic cylinder to the waist roll is raised and lowered operation, the use of waist roll can reduce the noise generated during the operation of the equipment, and has a certain stability in the process of rising and falling.

[0008] Scheme three, this is the preferred scheme two, waist roll both ends diameter is 200mm, the middle diameter is 600mm. In order to match the height of the electric hydraulic cylinder and the distance between the upper and lower belts, the waist roll is set to two ends diameter 200mm, middle diameter 600mm, which can enhance the guiding of the material.

[0009] Scheme four, this is the preferred scheme two, the wear-resistant layer is rubber material. Rubber material has the advantages of reducing noise and vibration, which can reduce the noise in the process of belt transmission. In addition, the rubber layer can effectively wrap the waist roll with short ends and long middle, which plays a protective role.

[0010] Scheme five, this is the preferred scheme two, the electric hydraulic cylinder and the motor are electrically connected with the PLC control end. The motor is remotely controlled by the PLC control end to convey the belt, and the electric hydraulic cylinder is remotely controlled to rise and fall, so as to rise and fall the waist roll, which reduces the labor intensity.
