[0019] Please see Figure 1 , Figure 2 , Figure 3 The anti-blocking mechanism 8 includes a drive motor 81. The drive motor 81 is fixedly installed on the right end of the housing 1. The output end of the drive motor 81 is rotatably connected to the housing 1. A sealing ring 82 is rotatably sleeved on the outer side of the output end of the drive motor 81. The sealing ring 82 is fixedly connected to the housing 1. By designing the sealing ring 82, the connection between the output end of the drive motor 81 and the housing 1 can be sealed. A rotating rod 83 is fixedly connected to the left end of the output end of the drive motor 81. A connecting sleeve 84 is rotatably sleeved on the outer side of the rotating rod 83. A push rod 85 is hinged to the lower end of the connecting sleeve 84. A push block 86 is fixedly connected to the bottom of the push rod 85. A guide rod 87 is fixedly connected to the bottom of the inner wall of the housing 1. The guide rod 87 is slidably connected to the push rod 85. A through groove 88 is opened inside the push rod 85. The guide rod 87 is slidably connected inside the through groove 88. By designing the through groove 88, the push rod 85 can slide along the guide rod 87. By designing the anti-blocking mechanism 8, blockage during material feeding can be prevented.
[0020] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 The extension mechanism 9 includes a groove 91. The inside of the feed port 5 has a groove 91. A retaining ball 92 is movably sleeved inside the groove 91. There are multiple grooves 91, which are evenly distributed inside the feed port 5. By designing multiple grooves 91, the retaining ball 92 can roll into the grooves 91 at different positions. The retaining ball 92 is movably connected to the extension sleeve 6. A slider 93 is movably sleeved on the outside of the retaining ball 92. The slider 93 is slidably connected to the extension sleeve 6. A sliding rod 94 is fixedly connected to the outside of the slider 93. The sliding rod 94 is slidably connected to the extension sleeve 6. A second spring 95 is provided on the outside of the sliding rod 94. One end of the second spring 95 is fixedly connected to the slider 93, and the other end of the second spring 95 is fixedly connected to the extension sleeve 6.

The push rod 85 will move back and forth vertically along the guide rod 87. When the push rod 85 drives the push block 86 to move, the push block 86 can push the material inside the feeding port 5 to avoid the material blocking the feeding port 5 and affecting the recycling of the material.
[0023] When the material feeding height needs to be adjusted, simply pull the lever 96. The lever 96 will cause the extension sleeve 6 to move vertically. The extension sleeve 6 will cause the retaining ball 92 to slide along the groove 91. The retaining ball 92 will be squeezed by the inner arc surface of the groove 91 and will move horizontally. The retaining ball 92 will cause the slider 93 and the sliding rod 94 to move horizontally. The slider 93 will squeeze the second spring 95, which can separate the retaining ball 92 from the groove 91. As the extension sleeve 6 moves, the elastic action of the second spring 95 will give the slider 93 a reverse thrust, which can push the retaining ball 92 into the groove 91 in another position. This makes it easy to adjust the material feeding height, which can be adapted to different collection containers for feeding and can avoid the problem of dust during feeding.
