The conveying belt can be further provided with a flange and a transverse clapboard to prevent the water chestnuts from rolling off from the side or rolling back to the storage bin.

The front section of the drum screen is also provided with a silt screen drum, and the rear section is a material screen drum. The silt screen cylinder is of a stainless steel screen structure and is used for separating silt adhered to the water chestnuts in advance, and soil adhered to the surfaces of the water chestnuts falls off from the stainless steel screen below the screening machine through rolling friction and collision of the silt screen cylinder section; the surface cleanliness of the water chestnuts can be improved, and the product phase is improved; in addition, the surface of the water chestnuts can be prevented from being damaged by small stones or gravels in the subsequent screening process, and the loss rate is reduced.

And a feeding plate is arranged between the conveying belt and the inlet at the end part of the roller screening machine. The feed plate is the zinc-plated screen cloth, inclines 20 to the screening machine entry, and both sides set up the backplate, and when the water chestnut fell on the feed plate from conveyer, massive mud piece and the grit that has separated can drop from the feed plate below, play the material and get into the preliminary treatment before the drum screening machine, reduce the handling capacity of drum screening machine processing sand mud.

The inner end part of the spiral clapboard is provided with a separation net which forms a closed spiral channel with the spiral clapboard. The separation net can be made of stainless steel net, and the functions of the separation net are as follows: when the water chestnut materials are excessive, the water chestnuts directly cross the lower screening part from the upper end of the spiral separation net, so that incomplete screening is avoided; after the separation net and the spiral partition plate form a closed spiral channel, the water chestnuts can only pass through the screening net holes of each stage one by one in a fixed path, and screening is more complete.

The inner lining of the material screen cylinder is a rubber layer. The rubber layer is pasted on the material screen drum lining of the stainless steel drum screen, and the water chestnuts are in direct contact with the rubber lining, so that the damage probability of collision of the water chestnuts and the rigid structure of the equipment is reduced.

And a supporting wheel is arranged at the inlet end and below the drum screen. Because water chestnuts enter from the central inlet of the end part of the rotary screen, in order to not influence the water chestnut feeding channel, the rotating shaft does not penetrate out of the inlet end of the rotary screen, only reaches the position of the sediment screen cylinder with the length of 85% of that of the rotary screen and stops, the spokes only reach the position to support the inner diameter of the rotary screen, the two groups of supporting wheels are arranged to contact with the two sides of the edge of the rotary screen and support the weight of the rotary screen, and the supporting wheels are only driven supporting rollers without a power device.
