Embodiment 1

[0021] A pre-sowing screening equipment for agricultural seeds, such as Figure 1-Figure 4 As shown, it includes a frame 1, a screening assembly, a drive assembly and a blanking assembly. The frame 1 is used to install the entire device. The drive assembly that provides power to push is provided at the top, and the rear right part of the frame 1 is provided with a blanking assembly that performs blanking by sliding.

[0022] When the seeds need to be screened, first pour an appropriate amount of seeds into the feeding assembly, then put the seed collection container under the screening assembly, start the drive assembly to work, so that the seeds in the feeding assembly slide down to the screening assembly , and then drive the screening component to screen the size of the seeds. After all the seeds are screened, close the drive component and take away the seed collection container.

[0023] like figure 1 and figure 2 As shown, the screening assembly includes a fixed plate ...

Embodiment 2

[0029] On the basis of Example 1, such as figure 1 , figure 2 and Figure 4 Shown, also include toggling bar 23, steel wire 24, pulley 241 and the 3rd spring 25, there is a word hole 221 in the lower part of dust removal frame 22 right sides, and the sliding type in the word hole 221 is provided with toggling lever 23, A steel wire 24 is connected between the toggle lever 23 and the first fixed rod 21. The right side of the dust removal frame 22 is rotatably provided with two pulleys 241. The steel wire 24 cooperates with the pulley 241. A third spring 25 is connected between them.

[0030]When the first fixed rod 21 moved forward, the steel wire 24 was pulled to move forward, and the third spring 25 was compressed to drive the toggle rod 23 to slide forward to stir the seeds. When the first fixed rod 21 moved backward, Under the effect of the third spring 25, the steel wire 24 and its upper device are moved backward and reset to stir the seeds again. In this way, the dust...

Abstract

The invention relates to screening equipment, in particular to a screening facility used before agricultural seed sowing. According to the technical problem to be solved, the screening facility used before agricultural seed sowing is provided and has the advantages that large and small seeds can be quickly screened, feeding operation can be intermittently conducted, and the seeds are fully screened. The screening facility used before agricultural seed sowing comprises a machine frame, a screening assembly, a driving assembly and a feeding assembly, wherein the machine frame used for achievinginstallation of the whole device, the screening assembly is installed on the machine frame and conducts screening in a sliding mode, the driving assembly is installed on the machine frame and providespower to conduct pushing operation, and the feeding assembly is installed on the machine frame and conducts feeding operation in a sliding mode. The screening facility used before agricultural seed sowing has the beneficial effects that the seeds with different sizes can be rapidly screened through the cooperation of fixing plates and a screening frame, and the enough power can be provided for size screening of the seeds through the cooperation of an abnormally-shaped rod and push rods.

Description

technical field [0001] The invention relates to a screening device, in particular to a screening device before sowing agricultural seeds. Background technique [0002] Agricultural seeds, the so-called agricultural seeds refer to plant organs that can be directly used for sowing in agricultural production. In order to distinguish them from botanical seeds, the seeds need to be separated by size before sowing. [0003] Patent Publication No. CN207695122U discloses a slow-falling and tumbling seed screening device, including a dust removal screen, a slow-falling and rolling gear lever, a seed screening box and a seed selection screen. The top of the seed screening box is welded with seeds Input pipe, the upper end of the seed input pipe is welded with an adding hopper, and a dust removal screen is installed in the seed screening box below the seed input pipe. When it is screened on the dust removal screen, the seeds tumble and fall, so that the seeds are dispersed again, avoi...
