Wheat impurity removal screening device for mechanical agricultural processing

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a wheat impurity removal screening device for mechanical agricultural processing. The wheat impurity removal screening device comprises a shell, wherein an impurity removal box is slidably connected to the interior of the shell, first springs are arranged between the bottom of the impurity removal box and the lower side wall of an inner cavity of the shell, a control valve is arranged at the top of the impurity removal box, a hopper is arranged at the top of the control valve, and a second screening plate ismovably connected to the position, opposite to the lower side of the control valve, of the inner wall of the impurity removal box. According to the wheat impurity removal screening device for mechanical agricultural processing, the impurity removal box moves downwards to drive a speed change device to change the vibration frequency of a vibration device, and the screening impurity removal speed isincreased; the control valve is automatically adjusted to close feeding according to the stress change of the speed change device, and aggravated blockage is prevented; and when the control valve isclosed, a socket is driven to start heating wire nets, wheat drying is accelerated, it is avoided that meshes are blocked due to moisture, and thus the screening impurity removal efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a mechanical wheat impurity removal and screening device for agricultural processing. Background technique [0002] Wheat is the general name of wheat plants. It is a monocotyledonous plant and a gramineous plant widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be used to make bread, steamed buns, biscuits, and noodles. After fermentation, food can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. Wheat is one of the most common crops in life. After harvesting, wheat needs to be stored. Before storage, it needs To remove impurities in wheat, that is, to remove impurities such as awns in wheat. [0003] At present, screening devices are mostly used in the market to screen and remove impurities from wheat, but the screening efficiency of existing screening d...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mechanical wheat impurity removal and screening device for agricultural processing, which has the advantages of sufficient impurity removal, high screening efficiency, automatic cleaning of separated impurities, and automatic increase of screening rate according to the gravity change of the screened wheat , when blockage occurs, the feeding will be automatically closed, the heating and dehumidification of wheat will be automatically controlled, and the advantages of high degree of automation will solve the problem of insufficient impurity removal in existing devices, low screening efficiency, difficult cleaning of separated impurities, and inability to screen wheat according to the requirements Gravity changes automatically increase the screening rate. When clogging occurs, if you continue to feed, it will cause aggravated clogging and affect the screening efficiency. The heating and dehumidification of wheat cannot be automatically controlled, and the degree of automation is low.
