Problems solved by technology

[0002] Generally speaking, sieving refers to a process of selecting a certain substance with specific properties from among the majority of substances according to a predetermined goal. In order to improve the germination rate of seeds, the seeds need to be sieved before planting, but , the existing seed screening is generally carried out by manually lifting the seeds for screening, which not only wastes time, but also has low work efficiency
[0003] In view of the above problems, the existing patent announcement number is CN207996796U, which discloses a screening device, but there is a problem in this device when it is working: because the material filtered by the upper filter in the device will be evenly distributed in the lower filter. Online, this leads to the extremely short secondary screening time of some materials during secondary screening, which is not conducive to effective screening of materials

Embodiment 1

[0024] see Figure 1~3 , in an embodiment of the present invention, an agricultural seed screening device includes a box body 1, a base 9 is provided under the box body 1, a buffer mechanism is provided between the base 9 and the box body 1, and the buffer mechanism includes symmetrically arranged The support sleeve 10 on both sides of the upper end of the base 9, the sliding cover at the upper end of the support sleeve 10 is provided with a support rod 11, the upper end of the support rod 11 is connected and fixed with the casing 1, and the inside of the support sleeve 10 is provided with a buffer spring, which connects the support rod 11 and the support The sleeve 10 is connected and fixed, thereby improving the cushioning performance of the device.

[0025] The upper left end of the box body 1 is provided with a feeding port 4, the upper end of the feeding port 4 is provided with a guide hopper 41, and the lower end of the guide hopper 41 is provided with a rectangular mate...

Embodiment 2

[0031] The difference from Example 1 is that in order to improve the drying effect, the No. 1 filter plate 17, the No. 2 filter plate 6 and the No. 3 filter plate 7 are made of stainless steel materials, and the heat transfer is facilitated by the arrangement of metal materials. , thus contributing to the drying of materials.

Abstract

The invention discloses an agricultural seed screening device which comprises a box body, wherein a base is arranged below the box body; a buffering mechanism is arranged between the base and the boxbody; and a first filtering plate, a second filtering plate and a third filtering plate are arranged in the box body. The agricultural seed screening device improves the defects in the prior art; under the action of a guiding plate, material slides to the highest end of the corresponding filtering plate, so that the material can obtain the longest filtering time to eliminate the defects of the existing device; under the action of a hot-air blower, hot-blast air enters a caching box and a flow guiding cavity along an air guiding tube and then spray out from an air ejector tube to carry out blow-drying treatment on the material on the surfaces of the filtering plates, so that drying of the material is facilitated; and the drying manner increases the air blowing area and is high in practicality.
