[0021] The lifting mechanism also includes a first fixing ring 4 fixedly connected to the outside of the lower shell 1, a second fixing ring 6 fixedly connected to the outside of the upper shell 5, two hydraulic telescopic rods 7 are symmetrically installed on the upper end of the first fixing ring 4, and the telescopic ends of the two hydraulic telescopic rods 7 are fixedly connected to the lower end of the second fixing ring 6;

[0022] Among them, it also includes a sand removal mechanism, which is located inside the lower shell 1. The sand removal mechanism includes a connecting ring 9 arranged in the lower shell 1, a filter screen 10 is fixedly connected to the inner side of the connecting ring 9, a vibration motor 16 is fixedly connected to the lower end of the connecting ring 9, and a connecting cylinder 14 is fixedly connected to the left and right sides of the lower shell 1. Two sliding rods 15 are symmetrically fixedly connected to the lower end of the connecting ring 9. The lower ends of the two sliding rods 15 extend into the connecting cylinder 14 and are elastically connected to the inner bottom of the connecting cylinder 14 through a spring 17;

[0023] Among them, the upper end of the filter 10 is rotatably connected to the rotating shaft 11, and the outer side of the rotating shaft 11 is fixedly connected with a stirring rod 13 at equal intervals.
