At the same time, the threaded rod 35 is rotated, so that the slider 37 is rotated on the outer wall of the threaded rod 35 The front wall moves, and the slider 37 moves to drive the front limit block 30 to slide on the inner wall of the rectangular guide hole 36, thereby driving the front connecting plate 301 to move. The front connecting plate 301 moves to drive the front fixed plate 302 to move, so that the front arc plate 303 drives the hopper cover 304 to move. The hopper cover 304 moves to drive the rear fixed plate 302, the connecting plate 301, and the limit block 30 to move, so that the sliding sleeve 39 slides on the outer wall of the sliding rod 38, thereby improving the stability of the hopper cover 304 when it moves. The modular mixing structure 5 is moved to move, thereby driving the modular mixing structure 5 to be lifted or lowered. When the modular mixing structure 5 is lifted, the modular mixing structure 5 is contacted with the limiting effect at the same time, and the feeding port on the top of the hopper 2 is opened, which is convenient for the staff to load materials. When the modular mixing structure 5 is lowered, the reverse rotation of the conical tooth 1 307 further drives the half gear 424 to rotate, so that the movable plate 425 and the trapezoidal block 427 are in a horizontal state. When the fixing ring 3041 in the hopper cover 304 is driven to drive the modular mixing structure 5 to descend and When the inclined surfaces of the trapezoidal block 427 come into contact, the trapezoidal block 427 will be pushed so that the trapezoidal block 427 drives the rectangular guide rod 426 to slide on the inner wall of the rectangular through hole, and at the same time, the circular guide rod 428 will be pushed to slide on the inner wall of the circular movable hole 3, and the spring 1 429 will be squeezed. When the fixed ring 3041 drives the modular hybrid structure 5 to move to the bottom of the trapezoidal block 427, and the fixed ring 3041 stays on the top of the limiting sealing ring 305, the trapezoidal block 427 will be pushed by the spring 1 429 to be stuck on the top of the modular hybrid structure 5 to achieve the limiting effect.

When the fixed ring 3041 drives the modular mixing structure 5 to be lifted, the modular mixing structure 5 is contacted with the limiting effect at the same time, so that the modular mixing structure 5 can be lifted, so that the plug block 54 is separated from the inner wall of the rectangular groove 3043, and the fixed plate 52 is separated from the inner wall of the fixed ring 3041, so that the modular mixing structure 5 can be disassembled for maintenance and the stirring rod 56 can be cleaned.

[0036] Working principle of the present invention:

[0037] By starting the stepper motor 34, the rotating shaft 1 33 drives the threaded rod 35 to rotate, and the rotation of the threaded rod 35 causes the connecting shaft 1 306 to rotate accordingly, thereby driving the conical gear 1 307 to rotate. Since the conical gear 1 307 is meshed with the outer wall of the conical gear 2 411, it drives the connecting rod 1 412 to rotate on the inner wall of the fixed sleeve 1 413, thereby causing the conical gear 3 414 to rotate, and the conical gear 4 415 is driven to rotate through the rotation of the conical gear 3 414, so that the connecting rod 2 416 rotates on the inner wall of the fixed sleeve 2 4100 and drives the conical gear 5 417 to rotate, and the conical gear 6 418 is driven to rotate through the rotation of the conical gear 5 417, so that the connecting rod 3 419 rotates on the inner wall of the fixed sleeve 3 410 and drives the conical gear 7 4101 to rotate, and the conical gear 8 4101 is driven through the rotation of the conical gear 7 4101. 02 rotates, so that the connecting rod four 4103 rotates on the inner wall of the fixed sleeve four 4104, so that the gear one 4105 rotates, and the outer wall of the gear one 4105 meshes with the outer wall of the connecting plate two 4206, thereby driving the connecting plate two 4206 to move. When the connecting plate two 4206 is driven to move to both ends by the gear one 4105, the teeth of the gear one 4105 will contact the outer wall of the tooth block 4215, and drive the tooth block 4215 to move so that the double-hole slide plate 4214 slides on the outer wall of the fixed rod 4212, and squeezes the spring two 4213. When the teeth of the gear one 4105 pass the outer wall of the tooth block 4215, the gear one 4105 is engaged with the outer wall of the tooth block 4215. Spring 2 4213 pushes double-hole slide plate 4214 to make tooth block 4215 return to the tooth groove of gear 1 4105 again, so as to achieve the effect of gear limiting, and 4210 is moved to make connecting plate 2 4206 drive rack 4205 to move, and connecting plate 2 4206 is moved to drive connecting plate 3 4207 to make convex block 4209 slide on the inner wall of dovetail groove 4208, so as to improve the stability of connecting plate 2 4206 when moving, and the outer wall of rack 4205 is meshed with the outer wall of gear 2 4204, so that when rack 4205 moves, gear 2 4204 will be driven to rotate, and the rotation of gear 2 4204 drives The second connecting shaft 4202 rotates on the inner wall of the support sleeve 4203, thereby causing the worm 420 to rotate. The outer wall of the worm 420 meshes with the outer wall of the half gear 424, which will drive the half gear 424 to rotate. The rotation of the half gear 424 drives the limit rod 423 to rotate on the inner wall of the perforated support arc angle plate 422, thereby improving the stability of the half gear 424 during movement. The rotation of the half gear 424 drives the movable plate 425 to flip, thereby causing the trapezoidal block 427 to flip and release the limit of the modular hybrid structure 5. At the same time, the threaded rod 35 rotates, thereby causing the slider 37 to move on the outer wall of the threaded rod 35.The slider 37 is moved to drive the front limit block 30 to slide on the inner wall of the rectangular guide hole 36, thereby driving the front connecting plate 301 to move; the front connecting plate 301 is moved to drive the front fixed plate 302 to move, so that the front arc plate 303 drives the hopper cover 304 to move; the hopper cover 304 is moved to drive the rear fixed plate 302, the connecting plate 301, and the limit block 30 to move, so that the sliding sleeve 39 slides on the outer wall of the sliding rod 38, thereby improving the stability of the hopper cover 304 when moving; the hopper cover 304 is moved to drive the modular mixing structure 5 to be lifted or lowered; when driving the modular mixing structure 5 to be lifted, the limit effect is simultaneously exerted on the modular mixing structure 5, and the feeding port on the top of the hopper 2 is opened, so that the staff can load the materials; When the modular mixing structure 5 is lowered, the reverse rotation of the conical gear 1 307 will further drive the half gear 424 to rotate, so that the movable plate 425 and the trapezoidal block 427 are in a horizontal state. When the fixed ring 3041 in the hopper cover 304 drives the modular mixing structure 5 to descend and contacts the inclined surface of the trapezoidal block 427, the trapezoidal block 427 will be pushed so that the trapezoidal block 427 drives the rectangular guide rod 426 to slide on the inner wall of the rectangular through hole, and at the same time, the circular guide rod 428 will be pushed to slide on the inner wall of the circular movable hole 3, and the spring 1 429 will be squeezed. When the fixed ring 3041 drives the modular mixing structure 5 to move to the bottom of the trapezoidal block 427, and the fixed ring 3041 stays on the top of the limiting sealing ring 305, the trapezoidal block 427 will be pushed by the spring 1 429 to be stuck on the top of the modular mixing structure 5 to achieve the limiting effect.

[0038] When the fixed ring 3041 drives the modular mixing structure 5 to descend, the sealing cover 51 will be locked, and the driving motor 57 will be started to make the rotating shaft 55 drive the stirring rod 56 to rotate to mix the materials inside the hopper 2. When the fixed ring 3041 drives the modular mixing structure 5 to be lifted, and at the same time, the modular mixing structure 5 is contacted with the limiting effect, the modular mixing structure 5 can be lifted, so that the insert block 54 is separated from the inner wall of the rectangular groove 3043, and the fixed plate 52 is separated from the inner wall of the fixed ring 3041, so that the modular mixing structure 5 can be disassembled for maintenance and the stirring rod 56 can be cleaned.
