Problems solved by technology

[0003] Based on the discovery of the above-mentioned inventors, the existing seed screening equipment for agricultural planting mainly has the following deficiencies, for example: because the seed coat of the dried seeds is relatively dry, when the seeds are screened, by The sieve screen shakes to screen the seeds, and the seed coat will fall off when it is shaken, so that the shed seed coat and the screened seeds will be mixed together, resulting in the need to remove the seed coat mixed in the seeds after the seeds are screened once.

Embodiment 1

[0024] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows:

[0025] Its structure includes a main body 1, a control panel 2, and a feeding hopper 3. The side end of the main body 1 is provided with a control panel 2. The feeding hopper 3 is located at the top front end of the main body 1. The main body 1 includes a material guide device 11 , fan 12, collection box 13, screen 14, the material guide device 11 is arranged at the inner bottom of the main body 1, and the included angle with the horizontal plane is 15 degrees, the fan 12 is provided with four, and the horizontal Arranged at the side end of the main body 1 , the collection box 13 is installed at the bottom end of the material guiding device 11 , and the screen 14 is arranged directly above the material guiding device 11 .

[0026] The material guiding device 11 includes a material guiding groove 111, a sliding material groove 112, a ventilation groove 113...

Embodiment 2

[0030] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows:

[0031] The guide device 115 includes a guide block b1, a fixed plate b2, a guide groove b3, and a flow groove b4. The upper end surface of the guide block b1 is arc-shaped, and the fixed plate b2 is embedded in the bottom end of the guide block b1. , the diversion groove b3 is provided with two, and is arranged transversely on the upper end surface of the guide block b1, the flow groove b4 is located at the bottom of the diversion groove b3 at the bottom end, and the radian of the diversion groove b3 is from the bottom end upward The end gradually becomes larger, which is conducive to allowing the seed coat to move upward along the end face of the diversion groove b3.

[0032] The circulation groove b4 includes an airflow groove b41, an upper flow groove b42, an air storage block b43, a mounting seat b44, a swing piece b45, and a return spring b46. There...

Abstract

The invention discloses seed screening equipment for agricultural planting. The equipment structurally comprises a main body, a control panel and a feeding hopper, wherein the control panel is arranged at the side end of the main body, the feeding hopper is located at the front end of the top of the main body, the main body comprises a material guiding device, a draught fan, a collecting box and a screening net, and the material guiding device comprises a material guiding groove, a material sliding groove, a ventilation groove, an air inlet, a guiding device and a material collecting groove. The material sliding groove comprises a groove body, a splitter, an air storage groove, an air guide block, a ventilation groove and an air outlet, the air outlet comprises an air outlet groove, an air guide piece and an intercepting net, air flow generated by rotation of the air flow fan is used for driving fallen seed coats to move towards the material collecting groove, then the material collecting groove is used for guiding the seed coats to the collecting box for collection, seeds and the seed coats are separated, and a condition that the seeds and seed coats are mixed together and then are selected after being processed is avoided.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a seed screening device for agricultural planting. Background technique [0002] Seeds are the unique propagules of gymnosperms and angiosperms. It is formed by pollination and fertilization of ovules. The seeds are generally composed of three parts: seed coat, embryo and endosperm. In the process of agricultural planting, seeds need to be screened to select high-quality Seeds, to avoid the situation that poor-quality seeds cannot grow seedlings after sowing. [0003] Based on the discovery of the above-mentioned inventors, the existing seed screening equipment for agricultural planting mainly has the following deficiencies, for example: because the seed coat of the dried seeds is relatively dry, when the seeds are screened, by The sieve screen vibrates to screen the seeds, and the seed coat will fall off when it is shaken, so that the shed seed coat and the screened seeds w...
