[0030] The plurality of mud removing parts 6 are arranged at a predetermined distance along the axis of the mud removing shaft 5, and the diameter of the water chestnut is generally greater than 20 mm, so in this embodiment, the spacing between adjacent mud removing parts 6 is 20 mm;

[0031] The stirring mechanism comprises a plurality of stirring shafts 2 arranged side by side in the mounting bracket 1, and the outer wall of the stirring shaft 2 is provided with a plurality of stirring parts 4, which are inserted at intervals on the circumferential outer wall of the stirring shaft 2. The stirring part 4 is a rubber stirring rod, and a plurality of stirring parts 4 are arranged on the circumferential outer wall of the stirring shaft 2 in several rows, and the stirring parts 4 between adjacent two rows are staggered;

[0032] The stirring mechanism further comprises a stirring gear arranged at one end of the stirring shaft 2 and an idle shaft sleeve arranged at the other end of the stirring shaft 2. The stirring gear and the idle shaft sleeve are arranged at the same end of the plurality of stirring shafts 2 at intervals, respectively. At one end of the plurality of stirring shafts 2, the stirring gear and the idle shaft sleeve are arranged in the order of stirring gear, idle shaft sleeve, stirring gear, idle shaft sleeve. At the other end of the plurality of stirring shafts 2, the stirring gear and the idle shaft sleeve are arranged in the order of idle shaft sleeve, stirring gear, idle shaft sleeve, stirring gear. The stirring gear is used to transmit power, and the idle shaft sleeve only idles. The idle shaft sleeve comprises a sleeve body and a relief groove circumferentially formed on the outer side wall of the sleeve body. The stirring gear partially extends into the relief groove to avoid the stirring gear;

[0033] The mud removing mechanism further comprises mud removing gears arranged at both ends of the mud removing shaft 5. The mud removing part 6 is a rubber gear, and the toothed end of the rubber gear is arc-shaped. When the mud removing part 6 rotates, it will collide with the water chestnut with adhered mud, and then it will knock the mud off the water chestnut. The mud removing part 6 made of rubber material also effectively prevents damage to the water chestnut. The two rows of mud removing parts 6 on the adjacent two mud removing shafts 5 are staggered with each other, which improves the mud removing effect on the water chestnut;

[0034] The two mud removing gears at the same end of the adjacent two mud removing shafts 5 are engaged with the same stirring gear;

[0035] The driving device 3 comprises a rotating motor arranged on the mounting bracket 1. The output end of the rotating motor is in transmission connection with one of the stirring gears. Specifically, the output end of the rotating motor can be engaged with the outermost stirring gear through a driving gear;

[0036] A plurality of installation plates 7 are arranged side by side in the installation support 1, and the installation plates 7 correspond to the mud removing shafts 5 one by one. One side of the installation plate 7 is integrally provided with a plurality of groups of mud removing protrusions 8, and the mud removing protrusions 8 extend between the adjacent two groups of mud removing parts 6.

[0037] The installation plate 7 and the mud removing protrusion 8 can remove the mud stuck between the adjacent two groups of mud removing parts 6 when the mud removing shaft 5 rotates, thereby prolonging the service life of the mud removing mechanism and improving the mud removing effect of the mud removing mechanism on the water chestnuts.

[0038] In use, all the stirring shafts 2 and the mud removing shafts 5 rotate in the same direction. When the stirring shafts 2 and the mud removing shafts 5 rotate, the stirring parts 4 and the mud removing parts 6 mounted thereon rotate in the same direction. The stirring parts 4 hit the water chestnuts with mud, and the water chestnuts with mud move upward. Then, the water chestnuts with mud are pushed upward by the stirring parts 4 on the next stirring shaft 2, and the process is repeated. The mud removing parts 6 in the lower rows rotate in cooperation with the stirring parts 4 in the upper rows to form a force that promotes the water chestnuts to roll upward. Finally, the water chestnuts move to the top of the screening assembly. In actual conditions, a collecting box can be arranged directly below the top of the screening assembly, and the water chestnuts automatically fall into the collecting box.

[0039] During the upward movement of the water chestnuts, the stirring parts 4 hit the water chestnuts with mud, and part of the mud falls off the water chestnuts. Inevitably, the water chestnuts with mud hit the mud removing parts 6 when they roll upward, which can also separate the mud from the water chestnuts. The separated mud falls down through the adjacent mud removing parts 6 by gravity.

[0040] Preferably, the installation support 1 of the embodiment is provided with a claw mechanism 9 at one end of the stirring mechanism and the mud removing mechanism, which extends into the soil to enable the water chestnuts to enter the stirring mechanism and the mud removing mechanism.

[0041] Preferably, the installation plate 7 of the embodiment is arranged directly below the mud removing shaft 5, so that the scraped mud falls downward. The length of the mud removing protrusion 8 is adapted to the distance between the adjacent mud removing parts 6, thereby improving the mud removing effect. The distance between the end of the mud removing protrusion 8 away from the installation plate 7 and the circumferential outer wall of the mud removing shaft 5 is 2-5 mm, i.e., the mud removing protrusion 8 does not contact the outer wall of the mud removing shaft 5, thereby reducing the friction damage of the mud removing protrusion 8 and prolonging the service life of the mud removing protrusion 8.

[0042] Preferably, the installation plate 7 of the embodiment is detachably installed in the installation support 1, for example, by a bolt structure, which facilitates the replacement of the installation plate 7.

[0043] Preferably, the installation support 1 of the embodiment is further provided with a water chestnut, mud and root stem conveying mechanism 10.

[0044] For example, the water chestnut, mud and root stem conveying mechanism 10 comprises: a mounting frame arranged on the installation support 1;

[0045] A water leakage plate is arranged at the bottom of the mounting frame, and a water leakage hole is formed in the water leakage plate and communicates with the inner cavity of the mounting bracket 1.

[0046] A conveying unit is arranged in the mounting frame and above the water leakage plate, and is used for conveying the soil and rhizomes from one end of the water leakage plate to the other end of the water leakage plate.

[0047] A cutting device is arranged on the mounting frame and corresponds to the starting end of the conveying unit, and is used for cutting the rhizomes of the water chestnut.

[0048] The water chestnut soil and rhizome conveying mechanism 10 can remove the soil and rhizomes and convey the soil and rhizomes to the required position through the conveying unit. When conveying, the water in the soil and rhizomes can be leaked downward to the screening assembly through the water leakage hole in the water leakage plate, so as to play a certain flushing effect on the water chestnut treated by the stirring mechanism and the soil removing mechanism, and improve the soil removing effect on the water chestnut.

[0049] Of course, the water chestnut soil and rhizome conveying mechanism 10 is not limited to the above one.

[0050] As preferred, the mounting bracket 1 of the embodiment is further connected with the crawler-type motor vehicle 11 through an adjustable support, and the adjustable support is used for adjusting the inclination angle of the mounting bracket 1.

[0051] The adjustable support is selected according to the actual situation, and will not be described in detail here.
