Description

Technical Field

[0001] This utility model belongs to the field of seed screening technology, and in particular relates to a seed screening device for vegetable planting. Background Technology

[0002] In vegetable cultivation, seed quality directly affects the germination rate, growth vigor, and final yield of crops. Traditional seed screening mainly relies on manual selection or simple sieve sorting, which has problems such as low screening efficiency. Conventional screening methods are difficult to effectively separate shriveled seeds and empty husks, resulting in uneven seedling emergence after sowing and affecting agricultural production efficiency. Traditional equipment relies on manual operation for feeding and discharging, which is inefficient. Utility Model Content

[0003] The technical problem this invention aims to solve is that manual selection or simple sieve sorting has low screening efficiency, making it difficult to effectively separate chaff and empty shells. Traditional equipment relies on manual operation for feeding and discharging, resulting in low efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a seed screening device for vegetable planting, comprising a box body, a door hinged to the front side of the box body, openings on the bottom of the left and right sides of the box body, a collection box communicating with the interior of the box body fixedly connected to one side of the box body, and an opening and closing door on one side of the collection box, and further comprising...

[0005] The air separator assembly is located at the top inside the housing and includes an inner panel fixedly connected to the inner wall of the housing. The inner panel is arranged in a horizontal U-shape and the top of the inner panel is inclined. A fan is fixedly installed at the bottom inside the inner panel. A wide air hood is fixedly connected to the output end of the fan. The sides of the inner panel are provided with evenly distributed ventilation holes.

[0006] The screening assembly, located below the inner panel, includes a screening plate hinged to the inner wall of the box. The end of the screening plate passes through the box and is located outside the box. A uniformly distributed spring is fixedly connected between the screening plate and the side wall of the box.

[0007] Furthermore, a feed pipe is fixedly connected to the top of the box, and a horizontal conveying cylinder is fixedly connected to the inner wall of the box. The conveying cylinder and the feed pipe are connected. A servo motor is fixedly installed on the outer wall of the box. The output end of the servo motor is located inside the conveying cylinder and is rotatably connected to the inner wall of the conveying cylinder. A propeller blade is fixedly connected to the output end of the servo motor.

[0008] Furthermore, the bottom end of the conveying cylinder is provided with a discharge port, which is located above the inner plate.

[0009] Furthermore, a stepper motor is fixedly installed on the side wall of the box, and a cam is fixedly connected to the output end of the stepper motor and is located below the screening plate. A discharge plate is hinged to the inner wall of the box and is located below the cam. The end of the discharge plate passes through the box and is located outside the box. Two evenly distributed springs are fixedly connected between the bottom of the discharge plate and the bottom wall of the box.

[0010] Furthermore, a base plate is fixedly connected to the bottom of the screening plate, and the base plate is located on one side of the cam.

[0011] Furthermore, the top of the inner plate is fixedly connected with guide plates that are symmetrically distributed front and back, and the guide plates are inclined.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] (1) The propeller blades rotate at a constant speed to ensure that the seeds are conveyed evenly and continuously through the conveyor cylinder. The seeds fall into the top of the inner plate one after another through the feed port to avoid piling up. Under the action of gravity and the guidance of the guide plate, they fall naturally. The airflow generated by the fan is evenly diffused through the wide wind hood, effectively blowing light impurities such as chaff and shriveled shells in the seeds to the collection box to achieve preliminary sorting.

[0014] (2) The seeds on the screening plate roll down to the left along the inclined plate surface. The periodic rotation of the cam can intermittently hit the bottom of the screening plate, causing the screening plate to vibrate regularly under the elastic action of the spring, thus screening the seeds. The smaller seeds fall to the discharge plate and complete the grading process.

[0015] (3) While driving the screening plate, the cam also acts on the discharge plate, causing it to vibrate under the cooperation of spring two, which significantly improves the discharge efficiency of seeds. Attached Figure Description

Detailed Implementation

[0023] like Figure 1-3 As shown, a seed screening device for vegetable cultivation includes a box body 1, a door 2 hinged to the front of the box body 1, and openings on the bottom left and right sides of the box body 1. A collection box 3 communicating with the interior is fixedly connected to one side of the box body 1, and an opening and closing door 4 is provided on one side of the collection box 3. The device also includes an air separation component and a screening component. The air separation component is located at the top inside the box body 1, and the screening component is located below the inner plate 5.

[0024] like Figure 2-5 As shown, to avoid excessive seeds affecting the sorting effect during air separation, a feed pipe 11 is fixedly connected to the top of the box 1, and a horizontal conveyor cylinder 12 is fixedly connected to the inner wall of the box 1. The conveyor cylinder 12 and the feed pipe 11 are connected. A servo motor 13 is fixedly installed on the outer wall of the box 1. The output end of the servo motor 13 is located inside the conveyor cylinder 12 and is rotatably connected to the inner wall of the conveyor cylinder 12. A propeller blade 14 is fixedly connected to the output end of the servo motor 13. A discharge port 15 is provided at one end of the bottom of the conveyor cylinder 12 and is located above the inner plate 5. A guide plate 21 symmetrically distributed at the front and back is fixedly connected to the top of the inner plate 5. The guide plate 21 is inclined. The propeller blade 14 rotates at a uniform speed to ensure that the seeds are conveyed evenly and continuously through the conveyor cylinder 12. The seeds fall into the top of the inner plate 5 one after another through the discharge port 15 to avoid shoving. Under the action of gravity and the guidance of the guide plate 21, they fall naturally.

[0025] like Figure 2-5As shown, in order to screen out light impurities such as chaff and shriveled shells from the seeds, the air separation component includes an inner plate 5 fixedly connected to the inner wall of the housing 1. The inner plate 5 is arranged in a horizontal U-shape, and the top of the inner plate 5 is inclined. A fan 6 is fixedly installed at the bottom of the inner plate 5. A wide air hood 7 is fixedly connected to the output end of the fan 6. The inner plate 5 has evenly distributed ventilation holes 8 on its sides. The airflow generated by the fan 6 is evenly diffused through the wide air hood 7, effectively blowing light impurities such as chaff and shriveled shells from the seeds toward the collection box 3, thus achieving preliminary sorting.

[0026] like Figure 2-5 As shown, to improve the seed screening effect, the screening assembly includes a screening plate 9 hinged to the inner wall of the housing 1. The end of the screening plate 9 passes through the housing 1 and is located outside the housing 1. Evenly distributed springs 10 are fixedly connected between the screening plate 9 and the side wall of the housing 1. A stepper motor 16 is fixedly installed on the side wall of the housing 1. A cam 17 is fixedly connected to the output end of the stepper motor 16 and is located below the screening plate 9. A discharge plate 18 is hinged to the inner wall of the housing 1 and is located below the cam 17. The end of the discharge plate 18 passes through the housing 1 and is located outside the housing 1. The bottom of the discharge plate 18 is connected to the bottom wall of the inner wall of the housing 1. A set of evenly distributed springs 19 are fixedly connected to the bottom of the screening plate 9, and a base plate 20 is fixedly connected to the bottom of the screening plate 9. The base plate 20 is located on one side of the cam 17. The seeds on the screening plate 9 roll down to the left along the inclined plate surface. The periodic rotation of the cam 17 can intermittently strike the bottom of the screening plate 9, causing the screening plate 9 to vibrate regularly under the elastic action of the spring 10, thereby screening the seeds. Seeds with smaller particle sizes fall to the discharge plate 18 to complete the grading process. While driving the screening plate 9, the cam 17 also acts synchronously on the discharge plate 18, causing it to vibrate under the cooperation of the spring 19, which significantly improves the seed discharge efficiency.

[0027] In practical use, seeds are added through the feed pipe 11, and then the servo motor 13 and the fan 6 are turned on. The rotation of the propeller blade 14 can transport the seeds at a uniform speed and drop them into the top of the inner plate 5 through the discharge port. The seeds fall under the action of gravity and the guide plate 21. During the process, the air blown by the fan 6 can blow the chaff and shriveled shells in the seeds to the collection box 3 for unified collection. The seeds that fall on the screening plate 9 roll down to the lower left. The stepper motor 16 is turned on, and the rotation of the cam 17 intermittently hits the bottom of the screening plate 9, causing the screening plate 9 to vibrate under the action of the spring 10, thereby screening the seeds. Seeds with smaller particle sizes fall onto the discharge plate 18. The rotation of the cam 17 can also intermittently hit the discharge plate 18, thereby causing the discharge plate 18 to vibrate under the action of the spring 19, increasing the seed discharge speed. Collection boxes 3 can be set on both the left and right sides of the box 1 to collect the seeds falling from both sides. The bottom plate 20 can guide the falling seeds to avoid affecting the rotation of the cam 17.
