Description

Technical Field

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

[0002] In organic vegetable cultivation systems, seed quality is the primary factor determining crop health, yield, and whether the final product meets organic standards. High-quality seeds should have characteristics such as high germination rate, strong vigor, no disease, uniform size, and high purity. Organic seeds, especially some thin-skinned or uniquely shaped vegetable seeds, are prone to mechanical damage during mechanical transport, vibration, and collision, which affects the germination rate.

[0003] According to Chinese patent document CN222325755U, a seed screening device for organic vegetable cultivation is disclosed, relating to the field of organic vegetable cultivation technology. This invention includes a housing with a feeding box fixedly connected to its top. The top of the housing is connected to the lower end of the feeding box, and the lower end of the housing is hollow. A screening component is provided at one end of the housing, and an intermittent component is provided at one end of the feeding box. The screening component includes a first motor located at one end of the housing. A drive gear is fixedly connected to the output end of the first motor, and one end of the drive gear is rotatably connected to the housing. A first driven gear is meshed with the outer surface of the drive gear. This invention provides a seed screening device for organic vegetable cultivation that can quickly screen seeds, thereby improving the screening efficiency and preventing a large number of seeds from simultaneously falling onto the screen and clogging it.

[0004] While the above-mentioned device can prevent a large number of seeds from falling onto the screen at the same time and clogging the screen, it will eventually clog the screen due to the increasing amount of impurities screened out over a long period of time, affecting the screening efficiency of planting and making it impossible to remove impurities that are the same size as the seeds but lighter in weight.

A handle is fixedly connected to the surface of the collection box outside the housing. A waste bin is fixedly connected to the side wall of the housing, and the top of the waste bin has an opening.

[0007] Preferably, the feed hopper is a conical structure with a larger upper end and a smaller lower end, and has a discharge port. A rotating baffle is provided at the top of the mounting housing at the discharge port. A connecting shaft is fixedly connected inside the rotating baffle and is rotatably connected to the mounting housing. One end of the connecting shaft extends through to the outside of the mounting housing and is fixedly connected to a stop block. A limiting block is slidably connected to the surface of the mounting housing. The limiting block has a triangular cross-sectional shape, and the end of the stop block near the limiting block abuts against the inclined surface of the limiting block.

[0008] Preferably, the screening mechanism includes a screening box fixedly connected inside the mounting housing. A motor is fixedly connected to the outer wall of the mounting housing. One end of the screening box is rectangular and the other end is circular. The rectangular end of the screening box extends to the outside of the mounting housing and has a light impurity outlet. Guide plates are fixedly connected to both sides of the top and bottom surfaces of the mounting housing, located on the rotating baffle. The end of the guide plate away from the top of the mounting housing is fixedly connected to the surface of the screening box. The two guide plates are close to each other to form a channel for planting, and the channel is interconnected with the interior of the screening box. Two discharge baffles with the same left and right positions as the guide plates are fixedly connected to the bottom surface of the screening box, and the discharge baffles are interconnected with the interior of the screening box. A rotating shaft is rotatably connected inside the circular part of the screening box. Multiple blades are fixedly connected to the outside of the rotating shaft. One end of the rotating shaft extends to the outside of the mounting housing and is fixedly connected to the output end of the motor. The vibration mechanism is located below the two discharge baffles away from the screening box. The light impurity outlet is located above the opening of the waste bin.

[0009] Preferably, the vibration mechanism includes a filter plate located inside the screening mechanism and below the two discharge baffles at the end furthest from the screening box. Slider blocks are fixedly connected to both sides of the filter plate. Sliding grooves are formed on both sides of the mounting housing at the positions of the two sliders. One end of the filter plate extends to the outside of the mounting housing and is located above the top opening of the waste bin. The other end of the filter plate extends to the outside of the mounting housing and is fixedly connected to a connecting block near the center. A rack is fixedly connected to the surface of the connecting block. A mounting plate with an L-shaped cross-section is fixedly connected to the side wall of the mounting housing below the connecting block. Guide rods are fixedly connected to both sides of the side wall of the filter plate on the left and right sides of the connecting block. The guide rods extend to the outside of the mounting plate and are slidably connected to it. Springs are fixedly connected to the outside of the two guide rods between the side wall of the filter plate and the surface of the mounting plate.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model uses a screening mechanism to generate a transverse airflow through the rotation of blades, which can efficiently separate light impurities such as shriveled seeds and dust from seeds. The impurities fall directly into the waste bin through the light impurity outlet. The filter plate of the vibration mechanism can intercept large particles larger than the seeds through vibration screening. The inclined setting of the filter plate allows the impurities to slide into the waste bin automatically. The vibration mechanism uses spring buffer to achieve flexible vibration of the filter plate, avoiding mechanical damage caused by hard contact between the seeds and the equipment. It is especially suitable for thin-skinned and fragile organic vegetable seeds, effectively ensuring seed vigor and germination rate.

[0013] 2. The feed hopper of this utility model is equipped with a rotating baffle and a triangular limiting block. The size of the feed opening can be controlled by adjusting the rotation angle of the baffle, so as to avoid the large amount of seeds falling at one time and causing the screening mechanism to be congested. The filter plate of the vibration mechanism reduces seed accumulation through reciprocating vibration. Combined with the inclined structure, it further reduces the risk of blockage and ensures that the screening process is continuous and efficient. The collection box adopts a pull-out design and is equipped with an external handle, so as to easily and quickly remove the high-quality seeds after screening without disassembling the equipment.

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1 As shown, this utility model provides a seed screening device for organic vegetable cultivation, including a mounting housing 1. A feeding hopper 2 for adding seeds is fixedly connected to the top of the mounting housing 1. A screening mechanism 3 for removing impurities is provided inside the mounting housing 1 below the feeding hopper 2. A vibration mechanism 5 for screening is provided inside the mounting housing 1 below the screening mechanism 3. A pull-out collection box 6 is provided inside the mounting housing 1 below the vibration mechanism 5. A handle 7 is fixedly connected to the surface of the collection box 6 outside the mounting housing 1. A waste bin 4 is fixedly connected to the side wall of the mounting housing 1, and the top of the waste bin 4 has an opening. First, place the seeds to be screened into the feed hopper 2. Then, open the rotating baffle 21 to let the seeds fall naturally. When passing through the screening mechanism 3, impurities smaller than the seeds in volume and mass can be removed. Then, the seeds fall onto the vibrating mechanism 5, where impurities larger than the seeds in volume are screened out. Finally, the screened seeds fall into the collection box 6 for collection. Then, by grasping the handle 7, the collection box 6 can be pulled out to the outside of the mounting housing 1 to collect the seeds in the collection box 6. Finally, the screened impurities fall into the waste bin 4 for collection.

[0017] like Figure 2 As shown, the feed hopper 2 is a conical structure with a larger upper end and a smaller lower end, and has a discharge port. A rotating baffle 21 is provided at the top of the mounting housing 1 at the discharge port. A connecting shaft 22 is fixedly connected inside the rotating baffle 21 and is rotatably connected to the mounting housing 1. One end of the connecting shaft 22 extends through to the outside of the mounting housing 1 and is fixedly connected to a stop block 23. A limiting block 24 is slidably connected to the surface of the mounting housing 1. The cross-sectional shape of the limiting block 24 is triangular. The end of the stop block 23 near the limiting block 24 abuts against the inclined surface of the limiting block 24. When it is necessary for the seeds inside the feed hopper 2 to fall, slide the limiting block 24 away from the connecting shaft 22. After sliding, the limiting block 24 no longer restricts the stop block 23. At this time, the rotating baffle 21 and the stop block 23 will rotate along the connecting shaft 22 to open the discharge port, allowing the seeds inside the feed hopper 2 to fall into the housing 1. After the stop block 23 rotates, it will again contact the bottom of the limiting block 24. Continuing to slide the limiting block 24 can adjust the rotation angle of the rotating baffle 21, thereby adjusting the size of the discharge port and adjusting the falling rate of the seeds, preventing too many seeds from falling at once from affecting the screening effect of the screening mechanism 3.

[0018] like Figure 3As shown, the screening mechanism 3 includes a screening box 31 fixedly connected inside the mounting housing 1. A motor 33 is fixedly connected to the outer wall of the mounting housing 1. One end of the screening box 31 is rectangular and the other end is circular. The rectangular end of the screening box 31 extends to the outside of the mounting housing 1 and has a light impurity outlet 32. Guide plates 36 are fixedly connected to both sides of the rotating baffle 21 on the top and bottom surfaces of the mounting housing 1. The end of the guide plate 36 away from the top of the mounting housing 1 is fixedly connected to the surface of the screening box 31. The two guide plates 36 are close to each other to form a channel for planting, and the channel is connected to the screening box. The interior of the screening box 31 is interconnected. The bottom surface of the screening box 31 is fixedly connected to two discharge baffles 37 that are in the same position as the guide plate 36, and the discharge baffles 37 are interconnected with the interior of the screening box 31. The circular part of the screening box 31 is rotatably connected to a rotating shaft 34. Multiple blades 35 are fixedly connected to the outside of the rotating shaft 34. One end of the rotating shaft 34 extends through to the outside of the mounting housing 1 and is fixedly connected to the output end of the motor 33. The vibration mechanism 5 is located below the end of the two discharge baffles 37 away from the screening box 31. The light impurity outlet 32 ​​is located above the opening of the waste box 4. Motor 33 drives the rotating shaft 34, which is fixedly connected to the output end, to rotate, which in turn drives the blades 35 to rotate. The rotation of the blades 35 causes the air in the rectangular part of the screening box 31 to flow laterally. When the seeds fall through the discharge port, they all pass through the rectangular part of the screening box 31 under the guidance of the two guide plates 36. The rotation of the blades 35 generates a lateral airflow, which separates the shriveled seeds and dust impurities from the seeds. The plump seeds and larger impurities will continue to fall and fall into the vibrating mechanism 5 for further screening through the action of the two discharge baffles 37. The shriveled seeds and dust will be discharged through the light impurity outlet 32 ​​under the action of the lateral airflow and finally fall into the waste bin 4 for collection.

[0019] The speed of motor 33 can be adjusted according to the size of the seeds and the number of seeds falling at one time, thereby adjusting the size of the lateral airflow generated by blade 35 and improving the applicability of the device.

[0020] like Figure 4As shown, the vibration mechanism 5 includes a filter plate 51, which is located inside the screening mechanism 3 and below the ends of the two discharge baffles 37 away from the screening box 31. Slider blocks 52 are fixedly connected to both sides of the filter plate 51. Slide grooves 53 are provided on both sides of the mounting housing 1 at the positions of the two sliders 52. One end of the filter plate 51 extends through to the outside of the mounting housing 1 and is located above the top opening of the waste bin 4. A connecting block 60 is fixedly connected to the other end of the filter plate 51 near the center of the outside of the mounting housing 1. A rack 56 is fixedly connected to the surface of the connecting block 60. The mounting housing 1... A mounting plate 54 is fixedly connected to the side wall of the filter plate 51 below the connecting block 60. The mounting plate 54 has an L-shaped cross-section. Guide rods 59 are fixedly connected to the side wall of the filter plate 51 on both the left and right sides of the connecting block 60. The guide rods 59 extend to the outside of the mounting plate 54 and are slidably connected to the mounting plate 54. A spring 55 is fixedly connected to the outside of the two guide rods 59 between the side wall of the filter plate 51 and the surface of the mounting plate 54. A cylindrical gear 57 meshes with the outside of the rack 56. The cylindrical gear 57 is a half-tooth gear. A connecting rod 58 is fixedly connected to the shaft of the cylindrical gear 57. The connecting rod 58 is rotatably connected to the mounting housing 1. When the cylindrical gear 57 rotates, the rack 56 drives the connecting block 60 to move left and right during gear meshing. Further, the movement of the connecting block 60 drives the filter plate 51 to move. As the filter plate 51 moves, the slider 52 slides inside the groove 53. When the filter plate 51 slides to the right, it compresses the spring 55. Since the cylindrical gear 57 is a half-tooth gear, when it rotates to the toothless part, it no longer restricts the rack 56, allowing the filter plate 51 to return to its initial position under the action of the two springs 55. When the toothed part of the cylindrical gear 57 meshes with the gear, it again drives the filter plate 51 to slide to the right, compressing the spring 55. This cycle causes the filter plate 51 to vibrate, improving the sieving efficiency of seeds on the surface of the filter plate 51. The filter plate 51 has multiple filter holes that allow seeds to pass through. The vibration of the filter plate 51 causes the seeds to fall through the filter holes into the collection box 6 for collection.

[0021] like Figure 5 As shown, one end of the guide rod 59 extends through to the outside of the mounting housing 1 and is fixedly connected to a second transmission wheel 581. The end of the rotating shaft 34 away from the motor 33 extends through to the outside of the mounting housing 1 and is fixedly connected to a first transmission wheel 341. A belt 342 for transmission is provided between the first transmission wheel 341 and the second transmission wheel 581. When the motor 33 drives the rotating shaft 34 to rotate, it drives the first transmission wheel 341 to rotate. Under the action of the belt 342, it drives the second transmission wheel 581, the connecting rod 58, and the cylindrical gear 57 to rotate, so that the vibration mechanism 5 and the screening mechanism 3 can perform screening simultaneously.

[0022] A groove is provided on the side of the housing 1 near the waste bin 4, at the position of the filter plate 51, allowing the filter plate 51 to be tilted. The tilted arrangement of the filter plate 51 allows impurities larger than the filter holes to continuously move and eventually fall into the waste bin 4 for collection when the filter plate 51 vibrates.

[0023] The working principle of this utility model is as follows: First, the seeds to be screened are placed in the feed hopper 2. The sliding limiting block 24 causes the stop block 23 and the rotating baffle 21 to rotate, opening the discharge port and allowing the seeds to fall naturally. After falling into the screening box 31, the motor 33 is started to drive the blades 35 to rotate, generating a transverse airflow inside the screening box 31 to screen out impurities smaller than the seeds. The screened impurities fall into the waste bin 4 through the light impurity outlet 32 ​​for collection. The seeds continue to fall onto the surface of the filter plate 51. The vibration of the filter plate 51 causes the seeds to fall into the collection box 6 through the filter port. Larger impurities fall into the waste bin 4 through the grooves, improving the seed screening efficiency.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
