Agricultural wheat grain impurity removal device

Abstract

The invention discloses an agricultural wheat grain impurity removal device. The device comprises a box body, wherein a feed hopper is fixedly arranged at the top end of the box body; two first fixedseats and two second fixed seats are fixedly arranged in the box body; a first screen plate is arranged between the two first fixed seats in a sliding mode; a first screen mesh is fixedly arranged onthe first screen plate; a second screen plate is arranged between the two second fixed seats in a sliding mode; a second screen mesh is fixedly arranged on the second screen plate; two ends of the bottom surface of the first screen plate are fixedly connected with first chock blocks; two ends of the top surface of the second screen plate are fixedly connected with second chock blocks; a horizontalrotating shaft is arranged between the first screen plate and the second screen plate; the rotating shaft is fixedly connected with two cams; and a driving motor is fixedly arranged at one side of the exterior of the box body. The driving motor is adopted to drive the cams to rotate so as to enable the first screen mesh and the second screen mesh to shake up and down, thereby increasing the wheatgrain impurity removal speed and efficiency; and by arranging a fan, impurities in wheat grains can be separated more perfectly.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to an agricultural wheat grain removal device. Background technique [0002] In agricultural production, the harvested grain particles are mixed with a large amount of straw and other debris, such as granular grain such as rice and wheat. After drying the grain, it is necessary to remove the mixed debris in the grain. In the weather, the grain is lifted to the high altitude by manpower, and the wind separates the sundries and grain particles. This method is relatively backward and primitive. With the development of modern mechanical equipment, grain grains can be removed by mechanical equipment. [0003] The publication number is CN205650451U, and the invention titled "an agricultural production machine for removing impurities from wheat grains" uses an air jet device to spray a strong air flow to blow the impurities away from the wheat grains, but the impurities are blown away...

Problems solved by technology

[0003] The publication number is CN205650451U, and the invention titled "an agricultural production machine for removing impurities from wheat grains" uses an air jet device to spray a strong air flow to blow the impurities away from the wheat grains, but the impurities are blown away by the air jet. In the process of blowing away, because relatively strong airflow and wind pressure are needed to blow away the larger straw debris, it is easy to blow the wheat grains down to the debris collection bin during the blowing process, and the effect of debris removal is Not good, needs further improvement
