The box body is connected with a plurality of hydraulic telescopic oil cylinders, the hydraulic telescopic oil cylinder is connected with a shell, a material collecting box is placed on the box body, a feed inlet is provided on the top of the shell, a discharge outlet is provided on the bottom, a plurality of slide rails are connected to the top of the shell, an electric push rod is connected to the shell, the electric push rod is connected to the screening hopper, sliders are connected to both sides of the screening hopper, the slider is arranged in the slide rail, a connecting shaft is arranged in the shell, a gear is arranged on the connecting shaft, a conveying chain is arranged between the gears, a plurality of scrapers are connected to the conveying chain, and a motor is connected to the end of the connecting shaft;

[0004] The box body is provided with a box door;

[0005] The size of the screening hopper is larger than the size of the feed opening.

[0006] Beneficial effects of the utility model:

[0007] The utility model drives the screening hopper and the slide block to reciprocate along the slide rail by telescoping the electric push rod, thereby shaking out the materials concentratedly falling in from the feed port, thereby preventing the accumulation of materials caused by concentrated falling materials. In addition, after the materials enter the shell, the shell is bumped under the telescoping state of the hydraulic telescopic cylinders on both sides, thereby further shaking out the materials falling into the shell. The utility model further reduces the possibility of material accumulation and improves the efficiency of the scraper conveyor in conveying bulk materials.

[0008] The utility model sets the base as a box structure with a box door, which can be used to place sundries, thereby improving the practicality of the utility model. The utility model sets the material collection box above the box body, increases the initial height of the material collection box for transportation, reduces the bending degree of the transportation worker, facilitates the transportation operation of the worker, and improves the transportation efficiency of the material collection box.
