[0018] As a further improvement of the above scheme, the guide plates 14 are symmetrically connected to the two sides of the lower end of the conveying pipe 6, and the guide plates 14 are matched and clamped in the slide rails 8. The slide rails 8 are symmetrically arranged on both sides of the holes 9 on the hopper 2, and are used to limit the displacement of the lower end of the conveying pipe 6 to ensure that the displacement of the lower end of the conveying pipe 6 is always within the slide rails 8.
[0019] As a further improvement to the above scheme, guide rollers 13 are symmetrically arranged at intervals on the upper and lower outer walls of the feeding container 5, and the guide rollers 13 are matched and arranged in the guide grooves 12. The guide grooves 12 are symmetrically arranged on the adjacent vertical surfaces of the stand 4, and are used to guide the feeding container 5 when it moves up and down, thereby ensuring that the feeding container 5 moves up and down along the height direction of the stand 4.
[0020] As a further improvement to the above solution, the lower end of the slide rail 8 is connected to the base frame 3 in order to enhance the stability and strength of the slide rail 8 .
[0021] As a further improvement to the above scheme, the lower part of the slide rail 8 is connected to a blocking plate 7, the upper end of the blocking plate 7 is connected to the hopper 2, and the blocking plate is arranged directly below the hole 9 on the hopper 2.
