[0002] At present, scientific research institutions and geological survey units engaged in geological exploration need to conduct geotechnical tests, and many tests require the use of ring cutters. For example, the ring cutter method is usually used to measure density, which is simple and accurate. The ring cutter method uses a certain volume of ring cutters to cut soil samples so that the soil fills the ring cutter in the shape of the ring cutter. After the density measurement is completed, the test personnel must clean the ring cutters. The number of ring cutters ranges from dozens to hundreds. After the ring cutters are demolded, a large amount of sand and soil will adhere to the inner wall, making it difficult to clean. The traditional method of cleaning the ring cutters is to rinse with a faucet or wipe with a rag, which is time-consuming and labor-intensive and easy to damage the cutting edge. Since the inner side of the ring cutter has a sharp cutting edge, the test personnel are easily injured during the operation, and the waste of water resources for cleaning is relatively serious, and the work efficiency is low.

Fixed sliding rods are provided on both sides of the axial rod 10, and two side push-pull rods cooperating with the fixed sliding rods are provided on both sides of the central axis push-pull rod, and a sliding connection is formed between the two side push-pull rods and the fixed sliding rod, and a sliding rod bottom disc 12 is provided at the bottom of the central axis push-pull rod, and an annular brush 13 is fixed on the sliding rod bottom disc 12. A hand-held handle fixing plate 17 is provided at the top of the central axis push-pull rod 14, and the hand-held fixing plate 17 is connected to the upper part of the push-pull rods on both sides, and a hand-held handle 18 is installed on the top of the hand-held fixing plate. The hand-held handle 18 is rotated to drive the hand-held fixing plate 17, the push-pull rods 16 on both sides and the central axis push-pull rod 14 to rotate around the axial rod 10, thereby driving the annular brush 13 fixed to the bottom disc 12 of the sliding rod to rotate. Furthermore, a top fixing plate 15 is also provided at the upper part of the washing cylinder body, and the top fixing plate is provided with holes corresponding to the push-pull rods on both sides and the central axis push-pull rod, and the top fixing plate 15 can rotate in the washing cylinder body.

[0023] Since the ring knife is in a circular ring shape, the ring knife washing cylinder is cylindrical as a whole. The bottom support 1 of the cylinder body, the bottom fixed ring 3 and the bottom fixed disc 5 are further fixed by nuts. The bottom water inlet hole is used for water in and out during washing. The washing cylinder body is mainly made of ordinary rubber, which can save costs and is convenient for drying after washing. The inside of the cylinder body is an inner brush 7. A rubber groove is provided on the top of the bottom fixed disc, and the rubber groove coincides with the convex groove of the bottom disc 12 of the sliding rod. The screws fix the ring brush to the bottom disc of the sliding rod. The central axis push-pull rod 14 can rotate along the axial rod, and the push-pull rods 16 on both sides move up and down along the sliding rod. The hand-held lifting part is composed of a top fixed disc 15, a hand-held handle fixed disc 17 and a hand-held handle 18. When cleaning, place the demoulded ring knife into the washing cylinder along the annular gap of the washing cylinder, and place the washing cylinder into the pool. Water enters the cylinder through the bottom water inlet hole. Lift and rotate the hand-held handle 18 to drive the bottom annular brush 13 to repeatedly rotate up and down, clockwise or counterclockwise to wash the sand and soil on the inner wall of the ring knife. The inner brush in the cylinder washes the outer wall of the ring knife to ensure the washing quality. After washing, the ring knife can be poured out along the entrance. The operation is simple and flexible. The waste water can flow back to the pool along the bottom water inlet hole. The water in the pool can be reused repeatedly to avoid water resource waste and improve work efficiency.
