Grain screening and drying device for agriculture

Abstract

The invention discloses an agricultural grain screening and drying device, which comprises a drying chamber, a limit chute is symmetrically arranged on the left and right side walls of the drying chamber, a drying screen cylinder is horizontally arranged in the drying chamber, and a right end of a rotating nozzle is provided. A limit bearing seat is sleeved; a horizontal plate is arranged on the drying chamber, a left vertical plate and a right vertical plate are symmetrically arranged on the horizontal plate, a driving device is installed on the elliptical cam, and left limit plates are respectively arranged on the left and right sides of the elliptical cam and the right limit plate, the bottom ends of the left limit plate and the right limit plate are both provided with guide sliders slidingly connected with the horizontal plate; both ends of the screen plate extend to the outside of the drying chamber, the first extension plate and the second extension plate The bottom surface is provided with a boom, and the boom is rotatably provided with a swing rod. The structure of the invention is ingenious. The rotating nozzle is driven by the driving motor and drives the stirring block to turn and stir the grains, so that the grains are more dispersed. The jetted hot air dries the grains by wind, which greatly improves the drying effect of the grains.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural grain screening and drying device. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials by cultivating animals and plants. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. We use the growth and development laws of animals, plants and other organisms to obtain the approval of various departments through artificial cultivation, collectively referred to as agriculture. Agriculture is the basic product that supports the construction and development of the national economy. Simply put, it is a system in which human beings use their wisdom to change the natural environment, use the growth and reproduction of animals and pl...

Problems solved by technology

[0003] In the process of agricultural production, it is necessary to screen grains to separate grains of different sizes. The existing grain screening device is not effective in screening grains. Due to the needs of production, the grains must be baked. Dry processing, currently the screening and drying of grains are carried out separately, not only the screening and drying effects are not ideal, but also the workload is large and the work efficiency is low, which does not meet the current agricultural production needs
