Example Embodiment

[0020] The technical solution of this patent will be described in further detail below in conjunction with specific implementations:

[0021] See Figure 1-5 , An agricultural grain sieving device, comprising an operating box 1, a motor frame 22 is fixedly installed on the top of the operating box 1, a driving motor 23 is installed upside down on the motor frame 22, and the output shaft of the driving motor 23 is fixed coaxially with The drive shaft 24 penetrates the upper top of the operating box 1 in a vertical downward rotation type. The surface of the drive shaft 24 is sleeved and fixedly installed with a driving pulley 25. The right side of the drive shaft 24 is vertically rotated with a worm 21, The upper end of the worm 21 is rotatably connected with the top of the operation box 1 through a bearing. The surface of the worm 21 is sleeved and fixedly installed with a driven gear 20 meshing and connected with the driving pulley 25; On the worm wheel 17, a runner 18 is fixed ...

Abstract

The invention discloses an agricultural cereal grain screening device. The agricultural cereal grain screening device comprises an operation box; a motor frame is fixedly mounted at the top of the operation box; a driving motor is inverted on the motor frame; a driving belt wheel is fixedly mounted on the surface of a driving shaft in a sleeving manner; a worm rod is vertically and rotationally arranged on the right side of the driving shaft; a fixed pulley is rotationally arranged at the top in the operation box; a swing plate is rotationally arranged on the inner wall of the right side of the operation box; and an arc limiting support plate slidingly connected with an arc clamping arc plate is fixedly mounted on the inner side wall of the operation box. The agricultural cereal grain screening device is skillful in structure and reasonable in design, achieves a screening effect on cereal grains through clockwise and anticlockwise alternate rotation of a screening semi-spherical groove, prevents blockage of screening holes caused by high centralization of cereal grains, and effectively accelerates the cereal screening speed; and through the screening semi-spherical groove, swing ofthe rotating plate can be realized, so that the speed of the cereal grains falling into the screening semi-spherical groove is slowed down, and influence on the screening effect by excessive accumulation of the cereal grains in the screening semi-spherical groove is prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural grain sieving device. Background technique [0002] Cereals mainly refer to the seeds of grasses. Five grains mainly include rice, wheat, corn, etc. and other miscellaneous grains, such as millet, black rice, buckwheat, oats, barley, sorghum, etc. Through processing, grains provide humans with 50% to 80% of heat energy, 40% to 70% of protein, and more than 60% of vitamin B1 for humans. Cereals can vary greatly in their nutrient content due to different types, varieties, origins, growth conditions and processing methods. [0003] After the harvesting of the grain is completed, the quality of the grain particles is different due to the different growth conditions. The grain particles of different qualities need to be screened according to the different particle sizes to obtain the required particle size. range of grain particles, the existing grain...
