Screening equipment for agricultural production

Abstract

The invention discloses screening equipment for agricultural production. The screening equipment for the agricultural production comprises a box body, wherein loading and unloading openings are formedin a side wall of the box body, a feeding hopper is arranged at the upper end of the box body, and a plurality of screening mechanisms are equidistantly arranged in the box body in the vertical direction; the screening mechanisms comprise U-shaped frames horizontally arranged, and openings of the U-shaped frames face the loading and unloading openings; guide rods are correspondingly arranged on the two sides of each of the U-shaped frames, the two ends of each of the guide rods are both fixedly connected to the inner wall of the box body, two movable blocks are correspondingly and slidably connected to each two guide rods, and the movable blocks are correspondingly movably connected to the two side walls of the U-shaped frames; and screening nets are arranged on the inner sides of the U-shaped frames. According to the screening equipment for the agricultural production, the multi-stage screening of materials can be realized, the discharging is convenient and fast, the materials on thescreening nets can be slightly thrown upwards when screening is carried out, so that the materials are distributed more evenly, the screening is faster, and the net holes in the screening nets are effectively prevented from being blocked by the materials when the materials are thrown upwards.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a screening device for agricultural production. Background technique [0002] Refers to various plants cultivated in agriculture, a type of organisms, including food crops and economic crops (oil crops, vegetable crops, flowers, grass, trees). Edible crops are one of the sources of basic food for human beings. "Food is paramount to man", which expresses the relationship between man and food. Only a reasonable diet can bring health to human beings. Food self-sufficiency is the foundation of a country's sustainable development. The growth of crops is inseparable from Scientific and technological production technology, as well as machinery and equipment manufactured by new industries that can assist agricultural production. [0003] After the crops are harvested, large particles and debris will be brought into the crops during the harvesting process, and the debris ...

AI Technical Summary

Problems solved by technology

[0003] After the crops are harvested, large particles and debris will be brought into the crops during the harvesting process, and the debris needs to be removed. Most of the existing methods for removing large particles and debris in the crops are carried out by hand-held screens. Shaking screening, the screening efficiency is low, increasing the labor force of the user, wasting a lot of time of the user, and it is impossible to achieve multi-level screening, and the screening effect is poor
