A partition is vertically arranged in the box body, and a movable plate is arranged on the right side of the partition, and the movable plate is slidably connected with the inner wall of the right part of the box body. A hydraulic cylinder is arranged at the lower end of the movable plate, and the hydraulic cylinder is installed on the lower wall of the box body. A rectangular cover is fixedly penetrated on the partition;

[0006] The box body is provided with a discharge structure, which includes a second electric push rod installed on the right side wall of the box body, the second electric push rod is connected with a connecting rod, the connecting rod passes through the right side wall of the box body, the connecting rod is located at the inner end of the box body and is provided with a push plate matching the inner wall of the rectangular cover, the push plate is slidably connected to the inner wall of the rectangular cover.

[0007] Preferably, an inspection door is provided on the right side wall of the box.

[0008] Preferably, a cleaning door is provided on the left side wall of the box body.

[0009] Preferably, the first electric push rod and the outside of the hydraulic cylinder are both provided with dust covers.

[0010] The utility model has the following beneficial effects: the utility model has a reasonable structure and a novel design. When in use, the bucket cover is opened, and the second electric push rod is started to drive the push plate to move, and the material in the right part of the box body is discharged into the left part of the box body through the rectangular cover, and then falls into the feed hopper to complete the discharge. As the material in the right part of the box body gradually decreases, in order to ensure the discharge, the movable plate is driven to rise by the hydraulic cylinder to make the material in the right part of the box body rise, ensuring that the push plate can discharge the material into the feed hopper. During the discharge process, this solution remains closed throughout the whole process to avoid dust flying during the discharge process, thereby ensuring the working environment and reducing the work intensity.
