Description

Technical Field

[0001] This utility model relates to the field of vegetable planting screening technology, specifically an automated seed screening device for vegetable planting. Background Technology

[0002] Vegetable seed screening technology refers to the process of selecting and evaluating high-quality vegetable seeds to improve planting efficiency and yield. Currently, seed screening devices used in vegetable cultivation often result in some unselected seeds being directly discharged during the screening process due to the large number of seeds. This necessitates repeated screening of these unselected seeds by relevant personnel, increasing their workload and reducing efficiency. Furthermore, different vegetable seeds have different particle shapes, making the installation method of the screening components on the device crucial. Inability to effectively disassemble and reassemble these components can prevent the replacement of the appropriate screening components for different vegetable seeds, affecting the versatility of the seed screening device and reducing its overall effectiveness and efficiency.

[0003] Therefore, it is necessary to develop an automated seed screening device for vegetable cultivation. Utility Model Content

[0004] The purpose of this invention is to provide an automated seed screening device for vegetable cultivation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated seed screening device for vegetable planting, comprising a screening box, a guide plate installed on the upper part of one side outer wall of the screening box, an mounting base installed at the center of one side outer wall of the screening box, and a return box installed on the lower part of one side outer wall of the screening box.

[0006] A fixing seat is installed at the center of one side inner wall of the screening box.

[0007] Preferably, an inclined plate is installed on the upper part of the other outer wall of the screening box, and a feed hopper is installed on the top side of the screening box.

[0008] Preferably, a motor A is mounted on the top of the mounting base, and an elliptical block is mounted on the output shaft of the motor A.

[0009] Preferably, a motor B is installed at the bottom of the return material box, a rotating shaft is installed on the conveying shaft of the motor B, and an auger is provided on the outer wall of the rotating shaft.

[0010] Preferably, a discharge hopper is installed on the top of the return material box, a discharge port is provided on the lower part of one side outer wall of the return material box, and a return port is provided at the center of the other side outer wall of the return material box.

[0011] Preferably, a mounting plate is rotatably connected to one outer wall of the fixed base, and a mounting groove is formed on the surface of the mounting plate. Limiting plates are provided on the lower part of the inner walls on both sides of the mounting groove.

[0012] Preferably, a screw is provided on the top of the limiting plate, a screening plate is installed inside the upper part of the mounting groove, mounting holes are provided on both sides of the surface of the screening plate, the inner wall of the mounting hole is slidably connected to the outer wall of the screw, and a nut A is threadedly connected to the upper part of the outer wall of the screw.

[0013] Preferably, a U-shaped frame is rotatably connected to one outer wall of the mounting plate, a guide post is provided at the top of the U-shaped frame, the outer wall of the guide post is slidably connected to the inner wall of the guide plate, a spring is provided below the outer wall of the guide post, and a nut B is threadedly connected above the outer wall of the guide post.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By sliding the screening plate onto the screw on the mounting plate through the mounting hole, and setting the mounting plate on one side of the fixed seat inside the screening box by rotational connection, the elliptical block on the outer wall of the output shaft of motor A is set below the mounting plate. The vegetable seeds to be screened are fed into the screening box from the feed hopper and then slide naturally onto the screening plate by the inclined plate. The rotation of the elliptical block driven by motor A can make the mounting plate float up and down, achieving a vibration effect and improving the screening of vegetable seeds.

[0016] By extending one end of the mounting plate to the return port on the return box, some unscreened vegetable seeds can fall into the return box and be conveyed back to the screening box for re-screening by the auger inside the return box. This eliminates the need for personnel to repeatedly refill the unscreened vegetable seeds, minimizing the need for repeated screening of unscreened seeds and reducing the workload of relevant personnel. This effectively achieves automated screening for vegetable seed screening devices.

[0017] By allowing the screening plate and mounting plate to be detachable, it is easy to replace the screening plate with a matching one for different vegetable seeds. This avoids situations where different vegetable seeds cannot be screened due to a non-detachable screening plate, effectively improving the versatility of the seed screening device for vegetable cultivation, as well as its usage effect and screening efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution: an automated seed screening device for vegetable cultivation, please refer to... Figures 1-5The system includes a screening box 1, a guide plate 101 mounted on the upper part of one outer wall of the screening box 1, an inclined plate 102 mounted on the upper part of the other outer wall of the screening box 1, a feed hopper 103 mounted on one side of the top of the screening box 1, a mounting base 2 mounted at the center of one outer wall of the screening box 1, a motor A201 mounted on the top of the mounting base 2, an elliptical block 202 mounted on the output shaft of the motor A201, a return box 3 mounted on the lower part of one outer wall of the screening box 1, a motor B301 mounted at the bottom of the return box 3, and a conveyor shaft on the motor B301. A rotating shaft 302 is installed, and an auger 303 is provided on the outer wall of the rotating shaft 302. A discharge hopper 304 is installed on the top of the return box 3. A discharge port 305 is provided on the lower part of one side of the outer wall of the return box 3, and a return port 306 is provided at the center of the other side of the outer wall of the return box 3. A motor B301 is installed on the bottom of the return box 3 on the screening box 1, and the output shaft of the motor B301 is connected to the rotating shaft 302 by a coupling. According to the auger 303 on the outer wall of the rotating shaft 302, the motor B301 can drive and control the auger 303 to rotate forward or backward.

[0026] A fixed base 4 is installed at the center of one inner wall of the screening box 1. A mounting plate 401 is rotatably connected to one outer wall of the fixed base 4. The mounting plate 401 is rotatably connected to one side of the fixed base 4 inside the screening box 1, so that the mounting plate 401 has an up-and-down folding treatment on the fixed base 4. The surface of the mounting plate 401 has a mounting groove 402. Limiting plates 403 are provided on the lower part of the inner walls of both sides of the mounting groove 402. A screw 404 is provided on the top of the limiting plate 403. A screening plate 405 is installed inside the upper part of the mounting groove 402. The surface of the screening plate 405 has mounting holes 406 on both sides. The inner wall of the mounting hole 406 is slidably connected to the outer wall of the screw 404. A nut A407 is threadedly connected to the upper part of the outer wall of the screw 404. 05 The screw 404 is slidably installed on the limiting plate 403 through the mounting hole 406, and the nut A407 is tightened for fixation. The elliptical block 202 on the outer wall of the output shaft of the motor A201 is positioned below the mounting plate 401. Vegetable seeds requiring screening are fed from the feed hopper 103 into the screening box 1, and then naturally slide down the inclined plate 102 onto the screening plate 405. The elliptical block 202 is rotated by the motor A201, causing the mounting plate 401 to float up and down, achieving a vibration effect and improving the screening of vegetable seeds. By extending one end of the mounting plate 401 to the return port 306 on the return box 3, some unscreened vegetable seeds can fall into the return port 306. Inside the return bin 3, the seeds are conveyed again to the screening bin 1 by the auger 303 for re-screening. This eliminates the need for personnel to repeatedly re-feed unscreened vegetable seeds, minimizing the need for repeated screening and reducing the workload of personnel. This effectively automates the seed screening process. Once all seeds have been screened, the control motor B301 reverses, causing the auger 303 to convey the seeds to the discharge port 305 for discharge. The detachable design between the screening plate 405 and the mounting plate 401 allows for adjustments based on different vegetable seeds. Replace with a matching screening plate 405 to avoid situations where different vegetable seeds cannot be screened due to a non-removable screening plate 405. A U-shaped frame 408 is rotatably connected to one outer wall of the mounting plate 401. A guide post 409 is set at the top of the U-shaped frame 408. The outer wall of the guide post 409 is slidably connected to the inner wall of the guide plate 101. A spring 410 is set at the lower part of the outer wall of the guide post 409, and a nut B411 is threadedly connected to the upper part of the outer wall of the guide post 409. The U-shaped frame 408 is slidably connected to the inside of the guide plate 101 by the guide post 409, and the nut B411 is tightened. Based on the elastic vibration effect of the spring 410 on the outer wall of the guide post 409, combined with the rotating elliptical block 202,The screening process on the screening plate 405 of the mounting plate 401 is enhanced by vibration screening.

[0027] Working principle: When using this utility model, a motor B301 is installed at the bottom of the return box 3 on the screening box 1, and the output shaft of the motor B301 is connected to the rotating shaft 302 via a coupling. Based on the auger 303 on the outer wall of the rotating shaft 302, the motor B301 can drive and control the auger 303 to rotate forward or backward. One side of the mounting plate 401 is rotatably connected to one side of the fixed seat 4 inside the screening box 1, so that the mounting plate 401 has an up-and-down folding treatment on the fixed seat 4. The screening plate 405 is slidably installed on the screw 404 on the limiting plate 403 through the mounting hole 406, and the nut A407 is tightened for fixation. Based on the motor... The elliptical block 202 on the outer wall of the output shaft of A201 is positioned below the mounting plate 401. This allows the vegetable seeds requiring screening to be fed from the feed hopper 103 into the screening box 1, and then naturally slide down the inclined plate 102 onto the screening plate 405. Driven by the motor A201, the elliptical block 202 rotates, causing the mounting plate 401 to float up and down, achieving a vibration effect and improving the screening of the vegetable seeds. By extending one end of the mounting plate 401 to the return port 306 on the return box 3, some unscreened vegetable seeds can fall into the return box and be conveyed back to the screen by the auger 303 within the return box 3. The seeds are re-sorted within the selection box 1, eliminating the need for personnel to repeatedly re-add unsorted vegetable seeds. This minimizes the need for repeated sorting of unsorted seeds, reducing the workload for personnel and effectively automating the seed sorting process. Once all seeds have been sorted, the control motor B301 reverses, and the auger 303 reverses the flow to the discharge port 305 for discharge. The detachable design between the screening plate 405 and the mounting plate 401 allows for easy adjustment depending on the type of vegetable seed. Replace the screening plate 405 with a matching one to avoid situations where different vegetable seeds cannot be screened due to the inability to disassemble the screening plate 405. By sliding the U-shaped frame 408 to the inside of the guide plate 101 via the guide column 409 and tightening the nut B411, the elastic vibration effect of the spring 410 on the outer wall of the guide column 409, combined with the rotating elliptical block 202, enhances the vibration screening of the screening plate 405 on the mounting plate 401. This effectively improves the versatility of the vegetable seed screening device and also improves its performance and screening efficiency.
