Wheat impurity-removing device

Abstract

The invention discloses a wheat impurity-removing device. The wheat impurity-removing device comprises a drying chamber, a vibration screening device, a wind-selecting mechanism and a wheat collecting device, the drying chamber is located above the vibration screening device, the wind-selecting mechanism is located below the vibration screening device, the wheat collecting device is located below the wind-selecting mechanism, wheat enters the drying chamber from a feeding hopper, when a pressure sensor at the bottom of the drying chamber detects that the weight of the wheat in the drying chamber exceeds a specified value, addition of the wheat is stopped, a drying device is started to dry the wheat, when a humidity sensor detects that the humidity of the wheat meets requirements, the drying chamber opens a drying chamber discharging opening, the wheat enters the vibration screening device, a vibration motor drives the vibration screening device to vibrate, after impurities are removed by the vibration screening device, the wheat enters the wind-selecting mechanism, and awn of wheat and other light-weight impurities are removed. The wheat impurity-removing device is simple in structure and wide in application range, can automatically remove the impurities of the wheat and drying the wheat, and has the advantages of being high in impurity-removing efficiency and drying speed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wheat impurity removal device. Background technique [0002] As we all know, the maturity period of wheat is short, and it must be harvested immediately after maturity and stored in the sun. During the maturity period of wheat, it is now mostly harvested by combine harvesters. When encountering cloudy and rainy weather, the wheat cannot be dried in time, which will easily cause the wheat to rot, thereby causing economic losses to the farmers; moreover, the use of sunlight to dry occupies a large area, and the labor intensity of the farmers is high, and the harvested wheat contains awns. and other sundries, it needs to be raised manually to remove the sundries, which is labor-intensive. Contents of the invention [0003] The invention provides a wheat impurity removal device, which solves the problems in the prior art. The wheat impurity removal device has a si...
