Compared with the prior art, the invention has the beneficial effects that:

1. the second magnet and the first magnet are mutually attracted, the four blocks which are protruded are arranged on the second magnet and the first magnet, the magnets of the same kind and material are arranged on the second magnet and the first magnet, the larger the volume of the magnets is, the more magnetic coils are, the stronger the magnetism of the protruded parts is, so when the second magnet rotates, the protruded parts on the second magnet are vertical to the protruded parts of the first magnet, the attraction force between the magnets is the largest, the length of the spiral plastic is the shortest, then the second magnet and the first magnet rotate to the position where the protruded blocks are mutually staggered, the spring above pulls back the second magnet, then the length of the spiral plastic is the longest, when the spring pulls the second magnet, the spring has the largest pulling length which is smaller than the distance between the second magnet and the first magnet, so that the second magnet and the first magnet cannot collide with each other, and the second magnet moves back and forth, make spiral plastics also shaking incessantly, the connecting rod on the spiral plastics is inserted and is fixed at the edge of second magnet in the ring, the first half that is close to the second magnet of spiral plastics, and the shake that can be sharp is rotatory, to the chinese yam that just puts down, the soil on the clearance chinese yam, spiral plastics rotate and drive the chinese yam and rotate, then the shake that does not stop, very convenient when clearance soil is dry, and cleaning effect is good moreover, but is general to the clearance effect of wet soil.

2. The device is the five degrees with the angle of water flat line, so the angle of spiral plastics is also the five degrees, so when spiral plastics is cleared up the chinese yam, the chinese yam can slowly move down, the chinese yam removes the latter half of spiral plastics, the latter half is far away from second magnet, so the effect of vibrations is relatively poor, but also have less amplitude effect, spiral plastics's shape is circular above outstanding has three arc angle, it is effectual to the mud scraping of moist soil, because three outstanding angle is the arc shape, at the rotatory in-process of spiral plastics, be difficult for saving earth.

3. When the spiral plastics is put to the chinese yam and is cleared mud, when the chinese yam was located first half position, spiral plastics can be pressed down to the weight of chinese yam itself, it is more to make the region that the washing belt leaked, can brush the less dry soil of adhesion above the chinese yam, spiral plastics's rotation can make the chinese yam rotate, spiral plastics's shake can make the chinese yam shake, shake and rotatory not stopping make spiral plastics very good to the cleaning performance of chinese yam, when the chinese yam was pressed above, can add some additional weight, but do not influence spiral plastics's first half shake.

4. When the chinese yam removed spiral plastics's lower half, spiral plastics also can be pushed down to the chinese yam, make the cleaning zone large tracts of land wash the chinese yam, wet soil is scraped to the spiral plastics of microseism, the other end of chinese yam is kept away from to spiral plastics, spiral plastics can be outstanding, spiral plastics can stimulate straight-bar and triangular block removal, can block dead second bracing piece and first bracing piece, it presss from both sides tightly spiral plastics to make first bracing piece and second bracing piece be located some of spiral plastics, it presss from both sides to make the cleaning zone carry out the package to spiral plastics, the wet soil on the spiral plastics can be cleared up to the brush on the cleaning zone, the spiral plastics do not stop rotating, then the cleaning zone does not stop wash spiral plastics.

5. The chinese yam is when the pivoted, and the water jet of higher authority carries out the spray rinsing to the chinese yam, a week of chinese yam can be overall spray rinsing, and the water jet of higher authority also can wash spiral plastics and wash the wet soil above taking, and the range of rocking of spiral plastics first half is great, so wet soil is difficult to the adhesion on it, and spiral plastics are plastics, can prevent effectively that the chinese yam from being damaged.
