[0007] Further characterized in that the moving mechanism comprises a lead screw installed at the bottom of a support plate, an installation groove accommodating the lead screw is formed in the bottom of the support plate, one end of the lead screw is connected to a motor, and the sliding block is slidably arranged in the installation groove and threadedly connected to the lead screw.

[0008] Supporting columns are arranged at four corners of the supporting plate respectively, the bottom of each supporting column is fixedly connected with an anti-collision ring, and the bottom of each anti-collision ring is fixedly connected with a self-locking universal wheel.

[0009] The side of the storage box is provided with an observation hole and is installed with a transparent glass plate.

[0010] A group of upper fixing blocks and a group of lower fixing blocks are arranged at the feeding port, the upper fixing blocks and the lower fixing blocks are respectively provided with fixing grooves arranged oppositely, and the sealing cover plate is slidably clamped in the fixing grooves.

[0011] The sealing cover plate is provided with a handle with rubber cladding.

[0012] After the utility model is adopted, materials are loaded into the storage box from the side feeding port, the materials fill the whole discharge hopper, the storage box can be moved to the discharging position along with the sliding block, and the electric valve can be opened to send out the materials from the discharge port of the discharge hopper, the electric valve is directly installed at the discharge port position, the discharging flow can be accurately controlled, the problem that the materials are excessively taken out after a delay time from the time when the pressure sensor reaches the set value to the time when the opening at the bottom of the discharging pipe is completely closed is avoided, and the discharging precision is ensured.
