[0031] Rotating the adjusting wheel 502 drives the threaded rod 501 to rotate. After the threaded rod 501 rotates, it drives the connecting rods 504 on both sides of the base 2 to contract inward simultaneously, thereby driving the support columns 503 on both sides to slide inside the slideway on the base 2. After the support columns 503 move, they drive the adjusting plate 12 to rotate through the sliding grooves on the adjusting plate 12, thereby changing the angle of the side rollers 3, and further changing the bending angle of the conveyor belt 6. The angles of the sealing plate 8 and the rubber plate 9 rotatably connected to the base 2 also change accordingly, thereby changing the volume of the material guiding groove, enabling this device to change the volume of the material guiding groove according to the amount of materials entering the material guiding groove and preventing the materials from blocking the material guiding groove.

[0032] A conveyor belt 6 is arranged on the side rollers 3 and the main roller 4. The conveyor belt 6 is made of rubber material. A housing 7 is fixedly connected to the bracket 1.

[0037] After loosening the turning handle 115, the rotating cylinder 114 can rotate relative to the rotating shaft 112. Thus, the rotating cylinder 114 is driven to rotate by the turning handle 115, and then the curtain receiving cylinder 113 is driven to rotate by the rotating cylinder 114, so that the height of the curtain 116 changes. After the adjustment is completed, the turning handle 115 is tightened again, the rotating cylinder 114 cannot rotate, and the curtain receiving cylinder 113 cannot rotate either, thereby fixing the height of the curtain 116. Furthermore, the utility model can adjust the height of the curtain 116 according to the height of the materials in the guide chute, avoiding the materials pulling the curtain 116 and causing damage to the curtain 116.

[0038] The working principle of the utility model is as follows:

[0039] The utility model is movably connected with side rollers 3. The threaded rod 501 can be driven to rotate by rotating the adjusting wheel 502. After the threaded rod 501 rotates, the connecting rods 504 on both sides of the base 2 are simultaneously contracted inward, thereby driving the supporting columns 503 on both sides to slide in the sliding grooves on the base 2. After the supporting columns 503 move, the adjusting plate 12 is driven to rotate through the sliding grooves on the adjusting plate 12, thereby changing the angle of the side rollers 3, and further changing the bending angle of the conveyor belt 6.

As a result, the device can adjust the feeding speed according to the actual situation, avoiding the blockage and damage of the guide chute caused by a large amount of materials pouring in at the same time.

[0041] The utility model is provided with a curtain component 11. After loosening the rotary handle 115, the rotary cylinder 114 can rotate relative to the rotating shaft 112. Thus, the rotary cylinder 114 is driven to rotate by the rotary handle 115, and then the curtain winding cylinder 113 is driven to rotate by the rotary cylinder 114, so that the height of the curtain 116 is changed. After the adjustment is completed, the rotary handle 115 is tightened, the rotary cylinder 114 cannot rotate, and the curtain winding cylinder 113 cannot rotate either, thereby fixing the height of the curtain 116. Furthermore, the utility model can adjust the height of the curtain 116 according to the height of the material in the material guiding groove, avoiding the material pulling the curtain 116 and causing damage to the curtain 116.
