Problems solved by technology

[0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agricultural products need to be processed after harvesting. For example, people need to sieve wheat after harvesting and drying. Existing people Hand-held sieves are used to sieve the dried wheat grains into bags, which is not only labor-intensive, but also low-efficiency in sieving, and will cause sore arms, which is not conducive to people's health.
[0003] In order to solve the above problems, Chinese patent CN 108513756 A discloses an agricultural wheat screening device, which includes a base, a cylinder, a first L-shaped leg, a second L-shaped leg and other components, and the cylinder is located on the base Above, the lower part of the left side wall of the cylinder is connected with the first L-shaped leg, the lower part of the right side wall of the cylinder is connected with the second L-shaped leg, the lower end of the first L-shaped leg and the second L-shaped leg The lower end of the filter screen is connected to the top of the base, the filter screen is located in the cylinder body, the filter screen and the cylinder body are set to slide and fit, and the outer wall of the filter screen is provided with a semicircular groove, but the wheat needs to be manually lifted to a higher height during use. The location of the wheat enters the cylinder, which increases manpower consumption, and the impurities left on the filter screen after screening need to be cleaned up, which makes the device unable to work continuously. The straw is easy to block the filter screen, and the impurities with small particles remain in the wheat, which is not conducive to the screening of wheat

Embodiment 1

[0025] see Figure 1-6 , an agricultural wheat screening device, comprising a screening box 1 and a feeding cylinder 2, the bottom surface of the screening box 1 is fixedly installed with multiple groups of evenly distributed wheels 35, and the middle part of the left side of the screening box 1 is fixedly installed horizontally U-shaped support 6, the middle part of the upper surface on the left side of the support 6 is fixedly equipped with a vertical electric telescopic rod 7, and the upper end of the electric telescopic rod 7 is hinged with a feeding cylinder 2, and the left end of the feeding cylinder 2 is fixedly installed with the output shaft protruding to the right. A motor 4, the right end of the output shaft of the first motor 5 is fixedly connected with a screw rod 3 coaxial with the feeding cylinder 2, the upper surface of the feeding cylinder 2 is connected to the left side with a trumpet-shaped feeding hopper 4 at the top, and the lower surface of the feeding cyl...

Embodiment 2

[0027]On the basis of Embodiment 1, a third motor 29 with an output shaft protruding to the right is fixedly installed on the left side wall of the screening box 1 between the first support plate 18 and the second limit frame 16. The output shaft of the motor 29 is provided with a cam 24 of the same structure, a second connecting rod 25, a limit plate 26 and a connecting frame 27. The wall is located between the first support plate 18 and the third motor 29, and a trapezoidal first discharge plate 21 is fixedly installed on the upper surface, with the upper surface lower on the left and higher on the right. The first discharge port 22 on the side wall, the right side wall in the screening chamber 1 is located below the second support plate 28 and is fixedly installed with a trapezoidal second discharge plate 32 on the upper surface, which is high on the left and low on the right. The right side of the plate 32 is provided with a second discharge port 33 located on the right si...

Abstract

The invention relates to the technical field of agricultural screening devices, and discloses an agricultural wheat grain screening device. The agricultural wheat grain screening device comprises a screening box and a feeding barrel, multiple sets of evenly-distributed wheels are fixedly installed on the bottom face of the screening box, a transversely-arranged U-shaped support is fixedly installed in the middle of the left side face of the screening box, a vertical electric telescopic rod is fixedly installed in the middle of the upper surface of the left side of the support, the feeding barrel is hinged to the upper end of the electric telescopic rod, a first connecting rod is hinged to the right side of the lower surface of the feeding barrel, the lower end of the first connecting rod is hinged to the upper portion of the left side face of the screening box, and two first limiting frames symmetrically distributed front and back are fixedly installed on the upper portion of the right side wall in the screening box. The agricultural wheat grain screening device has the beneficial effects that wheat does not need to be lifted by manpower, manpower consumption is reduced, straw is prevented from blocking a first screening plate, automatic separation of impurities of different particle sizes is achieved, long-time operation can be achieved, and the screening efficiency is improved.
