A synchronous belt 10 is arranged between the first synchronization pulley 9a and the second synchronization pulley 9b.

[0027] Further, four support rods 11 are symmetrically arranged on the bottom of the fixing frame 2 along the vertical direction.

[0030] Further, a connecting rod 14 is arranged horizontally between two adjacent support frames 12. The central axis of the connecting rod 14 is perpendicular to the central axis of the first moving lead screw 4.

[0036] By setting the support frame 12, the first fixing holes 13a, etc., when the distance between the discharge pipe 3 and the conveyor belt needs to be adjusted, first pull out the four fixing rods 13c outwards in turn, so that the support rod 11 and the support frame 12 are disconnected, and then adjust the height of the hopper body 1 according to the need, so that the second fixing hole 13b is aligned with the adjacent first fixing hole 13a, and then the fixing rod 13c is inserted into the first fixing hole 13a and the second fixing hole 13b, and the connection between the support rod 11 and the support frame 12 can be realized; by setting the support frame 12, the support rod 11, etc., the distance between the discharge pipe 3 and the conveyor belt can be adjusted according to the size of the raw materials, so as to realize the feeding of different types of raw materials and improve the applicable range of the equipment.

[0037] By setting the connecting rod 14, the bottom of the connecting rod 14 is attached to the ground, thereby increasing the contact area between the support frame 12 and the ground and increasing the stability of the support frame 12.

[0038] By setting the moving plate 15, the first moving block 5 and the second moving block 8 are evenly distributed around the discharge pipe 3, thereby increasing the connection stability between the hopper body 1 and the first moving block 5 and the second moving block 8, and making the hopper body 1 move more stably during the movement.
