[0003] However, after the material is transported, stored and prepared, it is difficult to meet the use requirements of the color sorter. For example, grains, beans and plastic particles may form clumps. If these clumped materials directly enter the color sorter, they may carry inferior or non-target products through the color sorter, resulting in a decrease in the material grade screened by the color sorter. SUMMARY

[0004] The utility model discloses a discharge hopper for color sorter, solves the problem of clumping of materials directly put into the color sorter, and avoids the pollution of materials caused by clumped materials carrying inferior or non-target products through screening in the later processing.

[0006] Further, the rope net is vertically distributed in multiple layers, and the mesh holes of adjacent rope nets are staggered, thereby increasing the contact surface between the material and the rope net.

[0007] Further, the convex shaft on the surface of the mounting bracket has multiple convex shafts, the multiple convex shafts are linearly distributed along the surface of the mounting bracket, the belt pulleys connected to the multiple convex shafts are synchronously connected to the motor through a belt, and when the motor is started, the multiple convex shafts can be driven to eccentrically swing through the belt pulleys.

[0008] Further, a circular hard rubber ball seat is adhered to the surface of the rubber layer, and the rope net is connected to the rubber layer through the ball seat, thereby ensuring the stability of the connection of the rope net.

[0009] Further, extension ears are arranged on both sides of the rear mounting bracket, a screw thread penetrates through the extension ears and abuts against the surface of the guide pipe, the mounting bracket can be moved away from the guide pipe by rotating the screw, the mounting bracket can stretch the rubber layer, and the tension of the rope net between the rubber layers can be changed.

[0010] Further, the periphery of the mounting frame is spaced apart from the material guide pipe, and the spacing is greater than the eccentric distance of the convex shaft, so that the mounting frame does not collide with the material guide pipe when the mounting frame shakes under the action of the convex shaft.

[0011] Further, the coverage area of the mounting frame is greater than the area of the rope net covering rubber layer, so that each rope net is within the influence range of the mounting frame.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By arranging the rope net inside the material guide pipe, the material contacts the crisscrossed rubber ropes when passing through the material guide pipe, the rope net blocks and screens the material, if there is a lump in the material, the lump is naturally broken when contacting the rubber ropes during the falling movement, and the dispersed material leaves downward through the mesh, so that the material entering the color sorter through the material guide pipe is in a dispersed state.

[0014] 2. The motor drives the belt to rotate the belt pulley, so that the belt pulley drives the convex shaft to eccentrically rotate, the shaking generated during the eccentric rotation is transmitted to the rubber layer through the mounting frame, the rubber layer drives the rope net to shake when shaking, the activity range of the rope net inside the material guide pipe changes, and the shaking rubber ropes are more likely to break the lumps when contacting the lumps.
