After cleaning, the shut-off valve on the outer wall of the discharge pipe is opened. At this time, the starting motor 3 rotates counterclockwise, thereby guiding the raw wheat inside the cleaning tank 1 into the drain cylinder 9 through the screw rod 4. The shut-off valve is closed, and raw wheat and water are added to the cleaning tank 1. The starting motor 3 drives the screw rod 4 to rotate clockwise. At this time, when the two pulleys 5 rotate, they drive the support shaft 7 to rotate. When the support shaft 7 rotates, it drives the drive gear 14 to rotate. When the drive gear 14 rotates, it drives the driven gear 15 and the drain cylinder 9 to rotate. The rotation of the drain cylinder 9 can shake out the water in the raw wheat inside the drain cylinder 9, so that the raw wheat and water are quickly separated.

[0024] As a technical optimization of this utility model, the lower end of the draining cylinder 9 is embedded with a plurality of evenly distributed ball bearings 11, and the bottom surface inside the draining cylinder 10 is provided with an annular groove 12 that is in rolling connection with the plurality of ball bearings 11.

[0033] In this embodiment, the cleaned raw wheat can be conveniently stored using the collection box 20.

[0034] As a technical optimization of this utility model, the outer wall of the cleaning tank 1 is provided with an observation window.

[0035] In this embodiment: the amount of wheat and water added to the washing tank 1 can be observed through the observation window, and the amount of wheat added to the washing tank 1 is lower than the height of the upper drain pipe 18.

[0036] As a technical optimization of this utility model, a bearing is installed at the intersection of the support plate 8 and the support shaft 7.

[0037] In this embodiment, a bearing is installed at the intersection of the support plate 8 and the support shaft 7, and the support shaft 7 can be supported by the bearing cooperating with the support plate 8.

[0038] Working principle: When in use, the raw wheat to be cleaned and water are placed into the inside of the cleaning tank 1 through the feed port at the top of the cleaning tank 1. Starting the motor 3 can drive the rotating shaft 16 and the screw rod 4 to rotate clockwise, so that the raw wheat and water can be mixed and stirred through the screw rod 4 connected to it, thereby cleaning the raw wheat. After cleaning, the wheat chaff and straw fragments mixed in the raw wheat will float on the water surface due to their light weight. By opening the shut-off valve on the outer wall of the upper drain pipe 18, the water above the top of the raw wheat and the wheat chaff and straw fragments floating in the water can be easily discharged.

[0039] Then open the shut-off valve on the outer wall of the discharge pipe. At this time, start the motor 3 to rotate counterclockwise, so that the raw wheat inside the washing tank 1 can be guided into the draining tube 9 through the screw rod 4. Then close the shut-off valve and continue to add raw wheat and water into the washing tank 1. Start the motor 3 to drive the screw rod 4 to rotate clockwise. At this time, when the two pulleys 5 rotate, they will drive the support shaft 7 to rotate. When the support shaft 7 rotates, it will drive the drive gear 14 to rotate. When the drive gear 14 rotates, it will drive the driven gear 15 and the draining tube 9 to rotate. The rotation of the draining tube 9 can throw out the water in the raw wheat inside the draining tube 9, so that the raw wheat and water are quickly separated.

[0040] After separation, the water will enter the interior of the guide cylinder 10 through the mesh on the outer wall of the drain cylinder 9 and be discharged through the lower drain pipe 17. The separated raw wheat is inside the drain cylinder 9. By opening the shut-off valve on the outer wall of the discharge pipe below the drain cylinder 9, the drain cylinder 9 is still rotating. Therefore, the rotation helps to throw out the raw wheat inside the drain cylinder 9 and guide the raw wheat into the collection box 20.
