Embodiment 1

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

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

Embodiment 2

[0029] On the basis of Example 1, as figure 1 , figure 2 and Figure 4 As shown, it also includes a toggle rod 23, a steel wire 24, a pulley 241 and a third spring 25, a word hole 221 is opened in the lower part of the right side of the dust removal frame 22, and a toggle rod 23 is slidably provided in the word hole 221, A steel wire 24 is connected between the toggle lever 23 and the first fixing rod 21 , and two pulleys 241 are rotatably provided on the right side of the dust removing frame 22 . A third spring 25 is connected therebetween.

[0030]When the first fixed rod 21 moves forward, the steel wire 24 is pulled to move forward, the third spring 25 is compressed, and drives the toggle rod 23 to slide forward to toggle the seeds. When the first fixed rod 21 moves backward, the Under the action of the third spring 25, the steel wire 24 and its upper device are moved backward and reset to move the seeds again, so that the dust and impurities on the seeds can be better ...

Abstract

The invention relates to a screening device, in particular to a screening device for agricultural seeds before sowing. The technical problem to be solved by the present invention is to provide a pre-sowing screening device for agricultural seeds that can quickly screen large and small seeds and can intermittently cut and fully screen. A pre-sowing screening equipment for agricultural seeds, comprising: a frame, used for installing the entire device; a screening component, installed on the frame, for screening by sliding; a driving component, installed on the frame, providing power to push; The blanking component is installed on the rack, and the blanking is performed by sliding. The beneficial effect is that seeds of different sizes can be quickly screened through the cooperation of the fixed plate and the screening frame, and sufficient power can be provided for the size screening of the seeds through the cooperation of the special-shaped rod and the push rod.

Description

technical field [0001] The invention relates to a screening device, in particular to a screening device for agricultural seeds before sowing. 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 size of the seeds needs to be separated before sowing. [0003] Patent Publication No. CN207695122U discloses a slow-fall tumbling seed screening device, which includes a dust-removing screen, a slow-fall tumbling bar, a seed screening box and a seed selection screen, and seeds are welded on the top of the seed screening box The input pipe, the upper end of the seed input pipe is welded with an adding bucket, and a dust removal screen is installed in the seed screening box below the seed input pipe. During the screening time on the dust removal screen, the seeds roll and fall, so that the seeds are dispersed again...
