Screening machine for agricultural production

Abstract

The invention discloses a screening machine for agricultural production. The screening machine for agricultural production comprises a bottom plate; a plurality of stand columns are fixedly connectedto the upper end of the bottom plate, a box body is fixedly connected to the upper ends of the stand columns, a first through hole communicating with the inside and the outside is formed in the top surface of the box body, a hopper is fixedly connected into the first through hole, a second through hole communicating with the inside and the outside is formed in the side wall of the hopper, a stirring mechanism is rotatably connected into the second through hole, a plurality of first telescopic rods are fixedly connected to the top surface of the box body, a first screen is fixedly connected tothe lower ends of the first telescopic rods, the side wall of the first screen makes contact with the inner wall of the box body in an abutting mode, a plurality of second telescopic rods are fixedlyconnected to the bottom of the box body, the second telescopic rods are sleeved with springs, and the upper ends of the second telescopic rods are fixedly connected with a second screen. According tothe screening machine for agricultural production, through multiple times of screening, the screening effect is high, the automation degree is high, and the labor intensity of farmers is relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a screening machine for agricultural production. Background technique [0002] Agricultural machinery refers to various machinery used in the process of crop planting and animal husbandry production, as well as in the process of primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and Fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Screening machine is also a kind of agricultural machinery, which is indispensable in agricultural production. As people's living standards are getting higher and higher, the requirements for food quality...

AI Technical Summary

Problems solved by technology

As people's living standards are getting higher and higher, the requirements for food quality are also increasing, but the existing screening methods are not effective, and most of them are manually screened, which is labor-intensive; if the food is stored for a long time, it may be Agglomeration occurs, which requires us to optimize the screening of grain
