[0024] Refer to Figure 2 - Figure 3, the disassembly component 3 includes a drain port 31 opened at the bottom end of the outer cylinder 1. A filter plate 32 is arranged inside the outer cylinder 1. One side of the limiting block 4 close to the center of the outer cylinder 1 is clamped on one side of the top of the filter plate 32 close to the filter plate 32. One side of the limiting block 4 away from the center of the outer cylinder 1 is clamped on the outer surface of the outer cylinder 1. The limiting block 4 limits the top of the filter plate 32, so that the filter plate 32 can rotate stably with the outer cylinder 1. A filter net 33 is arranged on the surface of the filter plate 32 on the side close to the center of the outer cylinder 1. Inner grooves 34 are opened on both the upper and lower sides of the filter plate 32 on the side close to the center of the outer cylinder 1. A clamping block 35 is clamped inside the inner groove 34. The upper and lower sides of the filter net 33 are located inside the inner groove 34. The clamping block 35 inserts the filter net 33 into the inner groove 34, and the filter net 33 is limited on the surface of the filter plate 32. A winding wheel 36 is rotatably connected to the bottom end of the outer cylinder 1. A pull rope 37 is wound and connected to the surface of the winding wheel 36. A pressure spring 38 is fixedly installed on the bottom wall of the outer cylinder 1. One side of the pressure spring 38 close to the center of the outer cylinder 1 is fixedly connected to an abutting block 39. The outer cylinder 1 is slidably connected inside the support plate 22. The drain port 31 penetrates the bottom wall of the outer cylinder 1. The dehydrated water can be discharged through the drain port 31. One side of the pull rope 37 away from the winding wheel 36 passes through the drain port 31 and is fixedly connected to the abutting block 39. A clamping groove adapted to the abutting block 39 is opened on the surface of the filter plate 32. The operator can rotate the winding wheel 36 to pull the pull rope 37, so that the pull rope 37 moves the abutting block 39 to compress the pressure spring 38 and disengage from the clamping groove.
[0025] Refer to Figure 2 and Figure 4 , the dehydration component 5 includes a driving rod 51 fixedly installed at the center inside the outer cylinder 1. A telescopic rod 52 is fixedly connected to the surface of the driving rod 51. A return spring 53 is fixedly installed inside the telescopic rod 52. One side of the telescopic rod 52 away from the driving rod 51 is fixedly connected to a pressing plate 54. The combination of the telescopic rod 52, the return spring 53 and the pressing plate 54 has four and is circumferentially distributed on the surface of the driving rod 51. The bottom end of the driving rod 51 is fixedly installed with the driving end of a motor, and the motor is fixedly installed on the ground. The telescopic rod 52 extends under the action of centrifugal force and pushes the pressing plate 54. At this time, the pressing plate 54 will press the soil to squeeze out the water inside it.
[0026] Working principle: The operator pours the washed soil into the inner part of the outer cylinder 1. At this time, the driving motor drives the outer cylinder 1 to rotate, and the rotation of the outer cylinder 1 remains stable on the surface of the support plate 22. During the rotation of the outer cylinder 1, the soil inside it will be affected by the centrifugal force and adhere to the surface of the filter net 33. At this time, the water in the soil will move to the edge of the outer cylinder 1 through the filter net 33 and the filter plate 32 under the action of the centrifugal force, and then the water will flow out through the drain port 31;
[0027] At the same time, when the driving rod 51 rotates, the telescopic rod 52 will stretch the reset spring 53 under the action of centrifugal force and push the pressure plate 54 to move towards the direction close to the filter screen 33. At this time, the pressure plate 54 pushes the soil attached to the surface of the filter screen 33, so that the soil is squeezed by the pressure plate 54, so that the moisture in the soil is squeezed out, and then the moisture enters the inner wall of the outer cylinder 1 under the action of centrifugal force and is discharged.
[0028] When the dehydration is completed, the operator can pull the filter screen 33 hard, and the filter screen 33 will pull the card block 35 out of the inner groove 34. At this time, the filter screen 33 is separated from the filter plate 32. The operator can remove the filter screen 33 to clean it, and then pull the limiting block 4 upward to make it separate from the top of the filter plate 32, and then rotate the winding wheel 36 to pull the pull rope 37, and then the pull rope 37 will compress the pressure spring 38 and drive the abutment block 39 to separate from the card slot. At this time, the operator can pull the filter plate 32 upward and take it out, and then the operator cleans the filter plate 32, and then install the filter plate 32 and the filter screen 33 in the opposite way of the above method.
