A scraping component 13 for scraping off the material adhered to the inner wall of the lifting barrel 6 is provided on the stirring component 12.

[0026] The brake device is a prior art component known to those skilled in the art. The structure and principle of the brake device can be known to those skilled in the art through technical manuals or conventional experimental methods, so it will not be described in detail in this embodiment.

[0027] The lifting assembly includes two electric telescopic rods 14 symmetrically fixedly mounted on the bottom plate 1 , and the top ends of the electric telescopic rods 14 are fixedly connected to the bottom of the lifting shell 2 .

[0028] The crushing assembly 5 includes two crushing rollers 51 rotatably disposed in the crushing box 3, and the two crushing rollers 51 are arranged in parallel and spaced apart.

[0029] One end of the two crushing rollers 51 is rotatably connected to the inner wall corresponding to the crushing box 3, and the other ends of the two crushing rollers 51 penetrate the crushing box 3 and are fixedly connected to a rotating gear, and the two rotating gears are meshed with each other.

[0030] One of the crushing rollers 51 is transmission-connected to a first motor 52 , and the first motor 52 is fixedly mounted on the crushing box 3 .

[0031] In this design, the first motor 52 is started, and the first motor 52 drives the corresponding crushing roller 51 to rotate. Since the two rotating gears are engaged with each other, the rotating crushing roller 51 will drive the other crushing roller 51 to rotate synchronously, and the material will be sent to the crushing box 3 and be between the two parallel and spaced crushing rollers 51. As the crushing rollers 51 rotate, the material is squeezed and rubbed, and thus is crushed, so that the material added from the feed hopper 4 can be effectively crushed and crushed, which helps to fully mix the material.

[0032] The stirring assembly 12 includes a dividing block 121 fixedly installed in the crushing box 3, and the dividing block 121 is in a triangular structure.

[0033] Such a design, through the arrangement of the triangular structure dividing block 121, helps to guide the flow of materials and improve the uniformity of stirring.

[0034] A second motor 122 is disposed in the partition block 121 . A power output end of the second motor 122 is drivingly connected to a stirring shaft 123 . A plurality of stirring blades 124 are evenly disposed on the stirring shaft 123 .

[0035] The scraping assembly 13 includes two scraping plates 131 symmetrically arranged on both sides of the stirring shaft 123. The sides of the two scraping plates 131 facing away from each other are in contact with the inner wall of the lifting cylinder 6 respectively, and the sides of the two scraping plates 131 close to each other are fixedly connected to the stirring shaft 123 through multiple connecting rods 132.

[0036] When in use, start the second motor 122, and the second motor 122 drives the stirring shaft 123 to rotate. As the stirring shaft 123 rotates, the multiple stirring blades 124 evenly arranged thereon also start to move synchronously, thereby achieving stirring of the material. At the same time, during the stirring process, the stirring shaft 123 drives the two scraping plates 131 to move through the connecting rod 132, and the scraping plates 131 scrape the material adhering to the inner wall of the lifting cylinder 6.

[0037] This design not only allows the materials to be fully mixed, but also effectively cleans the materials adhering to the inner wall of the lifting cylinder 6 to avoid material accumulation, thereby not only avoiding material waste, but also avoiding the normal operation of the equipment affected by material adhesion, thereby improving overall efficiency.

[0038] The position limiting guide assembly 11 includes a moving groove 111 opened on the top of the bottom plate 1 , and the moving groove 111 is located between the two electric telescopic rods 14 .

[0039] Two roller grooves 112 are formed at the bottom of the movable groove 111 , and the roller grooves 112 are arranged along the length direction of the movable groove 111 , and the rollers 10 are matched with the corresponding roller grooves 112 .

[0040] Two limiting grooves 113 are symmetrically provided on the inner walls of both sides of the movable groove 111 , and movable blocks 114 are slidably connected in the limiting grooves 113 . The ends of the two movable blocks 114 close to each other are fixedly connected to the same unloading barrel 8 .

[0041] During specific use, first push the lower barrel 8 to the bottom of the lifting barrel 6 through the roller 10, then press the brake device to lock the lower barrel 8, and then start the two electric telescopic rods 14. The two electric telescopic rods 14 shrink and drive the lifting shell 2 to move downward. The lifting shell 2 drives the lifting barrel 6 to move downward synchronously, so that the fixed block 7 at the bottom of the lifting barrel 6 is inserted into the fixed groove 9 of the lower barrel 8. At this time, the electric telescopic rods 14 are stopped.

[0042] Then add materials into the feed hopper 4, and start the first motor 52 at the same time. The first motor 52 drives the corresponding crushing roller 51 to rotate. Since the two rotating gears are engaged with each other, the rotating crushing roller 51 will drive the other crushing roller 51 to rotate synchronously. The material will be sent to the crushing box 3 and be between the two parallel and spaced crushing rollers 51. As the crushing rollers 51 rotate, the material is squeezed and rubbed, and thus is crushed, so that the material added from the feed hopper 4 can be effectively crushed and crushed, which helps to fully mix the material.

[0043] After that, the material falls into the lifting cylinder 6 and finally falls into the discharge cylinder 8. During this process, the second motor 122 is started, and the second motor 122 drives the stirring shaft 123 to rotate. As the stirring shaft 123 rotates, the multiple stirring blades 124 evenly arranged thereon also start to move synchronously, thereby achieving stirring of the material. At the same time, during the stirring process, the stirring shaft 123 drives the two scraping plates 131 to move through the connecting rod 132, and the scraping plates 131 scrape the material adhering to the inner wall of the lifting cylinder 6.

[0044] When the materials are mixed evenly and need to be unloaded, the two electric telescopic rods 14 are started, the two electric telescopic rods 14 extend and drive the lifting shell 2 to move upward, and the lifting shell 2 drives the lifting cylinder 6 to move upward synchronously, so that the fixed block 7 at the bottom of the lifting cylinder 6 and the fixed groove 9 of the unloading cylinder 8 are separated, and when the lifting shell 2 moves to a suitable height, the electric telescopic rods 14 are stopped.

[0045] Afterwards, the brake device is turned on and the discharge barrel 8 is pushed. With the cooperation of the moving block 114 and the limiting groove 113 and the cooperation of the roller 10 and the roller groove 112, the discharge barrel 8 moves stably along a predetermined route to avoid shaking during the movement, which would cause the material in the discharge barrel 8 to splash out.

[0046] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
