[0023] Specifically, a hydraulic cylinder 2 is fixedly installed on the base 1, and a transmission device 3 is fixedly installed on the top of the telescopic end of the hydraulic cylinder 2, so that the hydraulic cylinder 2 can control the transmission device 3 to rise and fall, and a motor 4 and a dispersion shaft 401 are fixedly installed on the transmission device 3, and the motor 4 and the dispersion shaft 401 are connected through a driving wheel, a transmission belt and a driven wheel, so that the motor 4 can control the rotation of the dispersion shaft 401, and an impeller 402 is fixedly welded on the bottom of the dispersion shaft 401. Due to the special shape of the impeller 402, the dispersion shaft 401 and the impeller 402 can be dispersed. When the dispersion barrel 8 rotates, centrifugal force can be generated to achieve a dispersion effect, and the hydraulic cylinder 2 can control the transmission device 3 to drive the dispersion shaft 401 and the impeller 402 to leave and enter the dispersion barrel 8, so that it is convenient for the staff to collect the materials in the dispersion barrel 8 and to clean the dispersion barrel 8. A driving rod 5 is fixedly welded at the bottom of the transmission device 3, and a rack 501 is fixedly welded on the driving rod 5, so that the driving rod 5 and the rack 501 can be controlled to rise and fall by the hydraulic cylinder 2, and a gear 601 is meshed on the side of the rack 501 so that the rack 501 During lifting, the gear 601 can be controlled to rotate clockwise or counterclockwise. A screw rod 6 is fixedly welded in the middle of the gear 601 so that the screw rod 6 can rotate with the gear 601. Two moving plates 701 are spirally connected to the screw rod 6, and the moving plates 701 are slidably connected in the limit bin 201. The two ends of the screw rod 6 are rotatably connected to the side of the limit bin 201, so that when the screw rod 6 drives the moving plate 701 to rotate, the moving plate 701 will slide in the limit bin 201 due to the obstruction of the limit bin 201, so that the two moving plates 701 are mutually When the two plates move closer to or farther away from each other, a fixed plate 7 is welded on the movable plate 701, and the dispersion barrel 8 is located between the two fixed plates 7, so that the fixed plates 7 can fix or loosen the dispersion barrel 8 when the two plates move closer to or farther away from each other.

When the impeller 402 rises and leaves the dispersion barrel 8, the rack 501 will rise and drive the two fixed plates 7 to move away from each other, thereby releasing the dispersion barrel 8.

[0024] The working principle and use process of the utility model are as follows: first, the dispersion barrel 8 filled with materials is placed under the impeller 402, and the telescopic end of the hydraulic cylinder 2 is controlled to retract. At this time, the impeller 402 will descend into the dispersion barrel 8, and the rack 501 will also descend accordingly. The rack 501 drives the gear 601 to rotate, so that the screw rod 6 rotates in the limit bin 201, so that the two movable plates 701 are close to each other, and the movable plates 701 will drive the two fixed plates 7 to approach each other until the inner side surfaces of the two fixed plates 7 and the outer side surfaces of the dispersion barrel 8 are tightly fitted, thereby fixing the dispersion barrel 8 in the middle, and at this time, the motor 4 can be started to control the dispersion shaft 401 and the impeller 402 to start rotating, so as to disperse the materials in the dispersion barrel 8.
