The bottom of the electric telescopic column is fixedly installed at the top center of the wave component. When the telescopic end of the electric telescopic column moves up and down, it drives the hemispherical block to move synchronously and regularly pushes the transmission component. The bottom of the hemispherical block is fixedly installed on the top of the telescopic end of the electric telescopic column, so that the material on the top of the transmission component is flipped back and forth, thereby enhancing the effect of removing dirt from the surface of the material.

[0007] According to the above technical scheme, the vibration device includes an inclined rod, a sliding plate, a shield plate and a center arc plate. The top of the inclined rod is hinged at the right side of the outer wall of the telescopic end of the electric telescopic column. When the telescopic end of the electric telescopic column moves up and down, it drives the inclined rod to move left and right. The top of the sliding plate is hinged at the bottom of the inclined rod. The inclined rod drives the sliding plate to slide synchronously along the top of the wave component to prevent dirt from entering the interior of the wave component. The bottom of the shield plate is fixedly installed at the top edge of the sliding plate, and the back of the inner wall of the shield plate contacts the front edge of the transmission component. The sliding plate drives the shield plate to move synchronously. The right side of the center arc plate is fixedly installed on the left side of the shield plate.

The activated carbon plate relies on the vibration force to shake the falling material and accelerate the falling speed of the material. The top of the transmission rod is hinged to the right side of the inner wall of the collection box, and the round-hole rubber plate drives the transmission rod to move synchronously. The top of the round-hole rubber plate is hinged to the bottom of the transmission rod, and the bottom of the round-hole rubber plate contacts the top of the activated carbon board. When the activated carbon board moves up and down, it drives the round-hole rubber plate to slide left and right.

The inside of the roller is fixedly installed on the outer wall surface of the electric wheel, and the roller drives the hook plate to rotate synchronously. The back of the hook plate is fixedly installed on the outer wall surface of the roller.

The spring sheet is fixedly installed between the front side of the trapezoidal plate and the front side of the inner wall of the feed hopper. The trapezoidal plate squeezes the spring sheet to deform, and then the trapezoidal plate relies on the thrust caused by the recovery of the spring sheet to reset. The spring sheet reciprocates to hit the falling material in the center, and the top of the T-shaped plate is fixedly installed on the bottom of the spring sheet. The spring sheet drives the T-shaped plate to slide toward the center of the feed hopper, pushing the material falling along the inclined surface of the feed hopper in the center to prevent the material from deviating from the center of the transmission assembly when falling.

The spring sheet 76 reciprocates to hit the falling material in the center. The spring sheet 76 drives the T-shaped plate 77 to slide toward the center of the feed hopper 21, and pushes the material falling along the inclined surface of the feed hopper 21 in the center to prevent the material from deviating from the center of the transmission assembly 2 when falling.

[0042] When in use, the telescopic end of the electric telescopic rod 52 drives the L-shaped rod 61 to move up and down, and the L-shaped rod 61 drives the heating component 62 to move synchronously. When the heating component 62 moves up and down, its own heat coverage range is expanded to prevent the material from getting damp and mildewing, thereby extending the storage time of the material; at the same time, the heating component 62 drives the arc spring plate 63 to move synchronously, and relies on the arc surface of the arc spring plate 63 to flip the material, so that the material is heated more evenly, preventing uneven heating, and further accelerating the material drying speed; the L-shaped rod 61 drives the L-shaped plate 64 to move synchronously, and the L-shaped plate 64 drives the sliding ring 65 to slide up and down along the surface of the screw rod 66. Relying on the limitation of the spiral groove, when the sliding ring 65 slides up and down, the screw rod 66 generates a rotating force and starts to rotate, and when the screw rod 66 rotates, it drives the disc stirring plate 67 to rotate synchronously. When the disc stirring plate 67 rotates, it stirs the material, so that the bottom material is evenly dispersed, so that the material is spread flat on the bottom of the collection box 51, to prevent the material from piling up too thickly, which is not conducive to natural air drying, and further prevent mildewing.

[0043] The electric wheel 71 is started, and the electric wheel 71 drives the roller 72 to rotate synchronously, and the roller 72 drives the hook plate 73 to rotate synchronously. At this time, the material poured into the feed hopper 21 is thrown to the inner wall of the feed hopper 21 by the high-speed rotation of the hook plate 73 to generate an impact force, thereby preventing the material from agglomerating due to rainy weather and ensuring the individual granularity of the material; at the same time, relying on the shielding of the hook plate 73, the material is prevented from splashing out of the feed hopper 21 to a certain extent, thereby avoiding the waste of raw materials; when the electric wheel 71 rotates, it drives the pressing plate 74 to rotate synchronously, and the pressing plate 74 presses the trapezoidal plate 75 to slide to the left along the inner wall of the feed hopper 21, and the trapezoidal plate 75 squeezes the spring piece 76 to deform , then the trapezoidal plate 75 is reset by the thrust caused by the restoration of the spring sheet 76, and the spring sheet 76 is reciprocated in this way to make the spring sheet 76 reciprocate and agitate to hit the falling material in the center, preventing the position of some materials from being offset and unable to contact the hook-shaped plate 73, and further preventing the material from agglomerating; when the spring sheet 76 is deformed, it drives the T-shaped plate 77 to slide toward the center of the feed hopper 21, and pushes the material falling along the inclined surface of the feed hopper 21 in the center, preventing the material from deviating from the center of the transmission component 2 when falling, preventing the material from falling into the inside of the device body 1 to cause the waste of raw materials, and increasing the risk of damage to the device body 1 during operation, thereby avoiding delays in the material processing and slowing down the processing progress.
