Description

Technical Field

[0001] The utility model belongs to the technical field of seed screening instruments, and particularly relates to a soybean seed screening device. Background Art

[0002] Soybean is an important food crop and oil crop. The quality of its seeds is related to the yield and quality of crops. In order to improve the quality of seeds, soybean seeds need to be screened before planting to remove impurities, diseased grains, etc. in the soybean seeds, and leave plump and healthy seeds. However, the existing soybean screening instruments cannot scrape the soybean seeds while screening, resulting in easy blockage of the sieve holes and poor screening effect.

[0003] In the current prior art, such as the patent application number "CN202222110221.7" and the patent name "A Soybean Seed Shape Screening Device", "A support plate is installed above the side end of the bottom plate, and a screening component is installed at the front end of the support plate; the screening component includes a screening ring, a feeding port, a material distributing component, sieve holes, and a screening motor. In the soybean seed shape screening device of the utility model, the collection box is divided into different collection cavities by multiple partition plates, and each collection cavity corresponds to a blanking plate for separately collecting the screened soybeans, for screening soybean seeds, and rotating screening. When the material distributing fan blades drive the soybeans to shift, the surface of the sieve holes can be scraped, effectively preventing the sieve holes from being blocked, improving the screening efficiency, and facilitating collection after screening. The screening motor drives blanking while driving the screening, and the screening and blanking are completed simultaneously, reducing energy waste and screening costs." When the above device is in use, when soybeans pass through the sieve holes with different pore diameters in sequence, soybean seeds with different shapes and sizes are screened out from the sieve holes with different pore diameters, and finally separately converge into multiple collection cavities of the collection box, so as to screen the soybean seeds. However, small-sized soybean seeds will fall into the corresponding collection cavities through the large-pore sieve holes, resulting in the mixing of soybean seeds of different sizes and affecting the screening effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a soybean seed screening device that can better separately collect soybean seeds of different sizes and improve the screening efficiency of soybean seeds.

[0005] The soybean seed screening device includes a screening ring. A closing plate for closing the screening ring is arranged on the front side wall of the screening ring. The closing plate is hinged to the screening ring through a hinge seat. A plurality of through-hole groups are formed at the bottom of the screening ring. Each through-hole group includes a plurality of sieve holes. The pore diameter sizes of the sieve holes in each through-hole group are inconsistent. A fixing groove is formed at the bottom of the screening ring corresponding to each through-hole group. A plugging plate for plugging the sieve holes is arranged in the fixing groove. A through groove for the plugging plate to be inserted into is formed on the closing plate corresponding to the plugging plate.

[0006] Furthermore, a fixing plate located on the front side wall of the closing plate is provided on the front side wall of the plugging plate.

[0007] Furthermore, the aperture sizes of several through-hole groups increase sequentially from left to right.

[0008] Furthermore, a rotatable shaft is arranged inside the screening ring. Several fixing frames in a "U" shape are arranged on the rotatable shaft. A sleeve is sleeved on the fixing frame. Several dredging rods for dredging the screening holes are arranged on the outer side wall of the sleeve.

[0009] Furthermore, the dredging rod is made of rubber material.

[0010] Furthermore, the cross section of the fixing groove is in a "T" shape.

[0011] Furthermore, the closing plate is made of transparent material.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, several plugging plates are used to plug the screening holes of several through-hole groups. When screening soybeans, move one of the plugging plates to move it in the fixing groove. The plugging plate dredges the screening hole with the smallest aperture, so that the seeds with the smallest size among the soybean seeds pass through several screening holes and fall into the corresponding collection cavities in the collection box. Then, move the remaining plugging plates in turn to dredge the screening holes of several through-hole groups in turn, so that the screening holes with aperture sizes from small to large are dredged in turn. The soybean seeds fall into the collection cavities in the collection box through the screening holes with different apertures, which can better separate and collect soybean seeds of different sizes and improve the screening efficiency of soybean seeds.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present invention.

[0019] Embodiment

[0020] A soybean seed screening device described in this embodiment is as shown in Figure 1 , Figure 2 and Figure 3 and includes a screening ring 3. A closing plate 8 for closing the screening ring 3 is arranged on the front side wall of the screening ring 3. The closing plate 8 is hinged to the screening ring 3 through a hinge seat 7. A plurality of through-hole groups are formed at the bottom of the screening ring 3. Each through-hole group includes a plurality of screening holes 14. The aperture sizes of the screening holes 14 in each through-hole group are inconsistent. A fixing groove 11 is formed at the bottom of the screening ring 3 corresponding to each through-hole group. A blocking plate 9 for blocking the screening holes 14 is arranged in the fixing groove 11. A through groove for the blocking plate 9 to be inserted into is formed on the closing plate 8 corresponding to the blocking plate 9.

[0021] This embodiment improves the prior art with the application number of "CN202222110221.7" and the patent name of "A soybean seed shape screening device". Therefore, the component names of components such as the collection box 1, the blanking plate 2, the screening ring 3, and the closing plate 8 in this embodiment are all referred to the component names in this prior art.

[0022] A support plate is arranged on the rear side wall of the screening ring 3. The support plate and the screening ring 3 are connected through a plurality of connecting rods. A bottom plate is horizontally arranged at the bottom of the support plate. A collection box 1 with an upward opening is fixed on the top of the bottom plate. A feed inlet is formed at the top of the screening ring 3. A hopper is arranged at the feed inlet. A hinge seat 7 is welded or adhered to the side wall of the screening ring 3. An L-shaped hinge plate is hinged in the hinge seat 7. The movable end of the hinge plate is welded or adhered to the front side wall of the closing plate 8. Rotate the closing plate 8 so that it rotates around the hinge point of the hinge seat 7 under the drive of the hinge plate. The rear side wall of the closing plate 8 contacts the front side wall of the screening ring 3, thereby closing the opening on the front side wall of the screening ring 3. During use, the screening ring 3 is supported by the support plate and the bottom plate. Rotate the closing plate 8 so that it rotates around the hinge point of the hinge seat 7. The closing plate 8 closes the opening of the screening ring 3. Then, the soybean seeds are put into the interior of the screening ring 3 through the hopper, and the soybean seeds are screened through a plurality of through-hole groups at the bottom of the screening ring 3.

[0023] At least three through-hole groups are provided at the bottom of the screening ring 3, and a number of screening holes 14 are provided in each through-hole group. A fixing groove 11 is provided at the bottom of the screening ring 3 corresponding to each through-hole group. The fixing groove 11 is provided along the front side wall of the bottom of the screening ring 3, so that the plugging plate 9 can slide into the fixing groove 11 from the front side wall of the screening ring 3 to plug the through-hole group above the fixing groove 11. A through groove corresponding to the fixing groove 11 is provided on the closing plate 8. After the rear side wall of the plugging plate 9 extends into the through groove on the closing plate 8, it slides into the fixing groove 11 at the bottom of the screening ring 3. The rear side wall of the plugging plate 9 contacts the rear inner side wall of the fixing groove 11, thereby plugging the screening holes 14 of the through-hole group. And after the plugging plate 9 plugs the screening holes 14 of the through-hole group, the front side wall of the plugging plate 9 protrudes from the front side wall of the closing plate 8, which is convenient to move the plugging plate 9 by protruding, so that it moves back and forth under the limitation of the through groove and the fixing groove 11. And the cross section of the fixing groove 11 is in a "T" shape, and the cross sections of the through groove and the plugging plate 9 corresponding to the fixing groove 11 are both in a "T" shape, so that the plugging plate 9 can be smoothly embedded into the through groove and the fixing groove 11 to plug the screening holes 14, preventing the plugging plate 9 from falling out of the fixing groove 11 and making the movement of the plugging plate 9 smoother and more stable;

[0024] During use, the plugging plate 9 is sequentially embedded into the through groove and the fixing groove 11 from front to back. If the plugging plate 9 plugs the screening holes 14 of the through-hole group provided at the bottom of the screening ring 3, when the soybean seeds enter the screening ring 3 through the hopper, under the plugging action of the plugging plate 9, the soybean seeds are stored in the screening ring 3. When it is necessary to screen the soybean seeds, move the plugging plate 9 at the position where the aperture of the screening hole 14 is the smallest, so that the soybean seeds with the smallest size in the screening ring 3 fall through a number of screening holes 14 and drop into the collection cavity in the collection box 1. Then move several plugging plates 9 in sequence, so that the aperture sizes of the screening holes 14 of several through-hole groups gradually become unblocked from the smallest to the largest, and the soybean seeds are separated and dropped in sequence from the smallest size to the largest size, so as to separately collect soybean seeds of different sizes. And a blanking plate 2 is provided on both the left and right sides of each fixing groove 11. The top of the blanking plate 2 is welded or adhered to the bottom of the screening ring 3. The soybean seeds that fall to the bottom of the screening ring 3 through the screening holes 14 are guided by the blanking plate 2, so that the soybean seeds are specifically dropped into the corresponding collection cavity in the collection box 1, preventing the soybean seeds from falling into other collection cavities during the dropping process, thereby improving the screening effect of the soybean seeds and better collecting soybean seeds of different sizes, which is convenient for the subsequent cultivation of soybean seeds;

[0025] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a fixing plate 10 located on the front side wall of the closing plate 8 is provided on the front side wall of the plugging plate 9. The front side wall of the plugging plate 9 protrudes from the front side wall of the closing plate 8. The fixing plate 10 is welded or adhered to the front side wall of the plugging plate 9. By moving the fixing plate 10, the plugging plate 9 is driven to move in the through groove and the fixing groove 11 to block and dredge a plurality of screening holes 14 of the through hole group, ensuring that soybean seeds can fall from a plurality of screening holes 14 with different aperture sizes in a plurality of through hole groups, and the soybean seeds can be distinguished and collected according to their sizes, improving the screening effect;

[0026] As Figure 2 and Figure 3 shown, the aperture sizes of a plurality of through hole groups increase sequentially from left to right. For example, in this embodiment, there are three through hole groups. The aperture size of the screening hole 14 in the leftmost through hole group is the smallest, and the aperture size of the screening hole 14 in the rightmost through hole group is the largest. By moving the corresponding plugging plate 9 of the through hole group from left to right, the aperture sizes of the screening holes 14 are gradually dredged from small to large, so that the sizes of the soybean seeds in the screening ring 3 are gradually screened from small to large, which can prevent small-sized soybean seeds from falling through the large-aperture screening holes 14, and can more accurately distinguish and collect the soybean seeds, improving the screening efficiency; and the sizes of the soybean seeds in the collection cavities from left to right in the collection box 1 increase from small to large, making the screening of the soybean seeds more accurate and facilitating the subsequent planting and use of the soybean seeds;

[0027] As Figure 1 , Figure 2 and Figure 3 shown, a rotatable shaft 13 is provided in the screening ring 3. A plurality of fixing frames 6 in a "U" shape are provided on the rotatable shaft 13. A sleeve 4 is sleeved on the fixing frame 6. A plurality of dredging rods 5 for dredging the screening holes 14 are provided on the outer side wall of the sleeve 4;

[0028] A motor 12 is installed at the rear side of the support plate on the rear side wall of the screening ring 3. The motor 12 is installed on the rear side wall of the support plate. Fixing holes are provided on the support plate, and corresponding to the fixing holes, mounting holes are provided on the rear side wall of the screening ring 3. A rotating shaft 13 is provided at the output end of the motor 12. The movable end of the rotating shaft 13 sequentially passes through the fixing hole and the mounting hole and is located inside the screening ring 3. A storage battery for supplying power to the motor 12 is installed on the support plate. Start the motor 12 so that its output shaft drives the rotating shaft 13 to rotate freely inside the screening ring 3. A plurality of fixing brackets 6 distributed in a circumferential array along the center of the rotating shaft 13 are welded or adhered to the rotating shaft 13 inside the screening ring 3. The fixing bracket 6 includes two vertical rods and a cross bar. The cross bar connects the two vertical rods together. A sleeve 4 is sleeved on the cross bar. The sleeve 4 rotates freely on the cross bar of the fixing bracket 6. A plurality of dredging rods 5 are adhered to the outer side wall of the sleeve 4. During use, start the motor 12 so that its output shaft drives the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 drives a plurality of fixing brackets 6 to rotate inside the screening ring 3. The rotation of the plurality of fixing brackets 6 can drive the soybean seeds inside the screening ring 3 to move inside the screening ring 3, so that they can be better screened out from the screening holes 14. When the fixing bracket 6 rotates, the sleeve 4 on the fixing bracket 6 rotates on the fixing bracket 6, thereby stirring the soybean seeds inside the screening ring 3, so that the soybean seeds continuously fall through the screening holes 14. When the sleeve 4 rotates, a plurality of dredging rods 5 on its surface will insert into the screening holes 14 to dredge the screening holes 14 and prevent the screening holes 14 from being blocked, and can better screen the soybean seeds. The diameter of the dredging rod 5 is smaller than the minimum aperture of the screening hole 14, which is convenient for the dredging rod 5 to smoothly extend into the screening hole 14 to dredge the blocked soybeans. And the dredging rod 5 is made of rubber material. The rubber is soft and elastic. When the dredging rod 5 contacts the inner wall of the screening ring 3, it can avoid scratching the inner wall of the screening ring 3. And the dredging rod 5 has greater elasticity. When the dredging rod 5 is inserted into the screening hole 14, it can push the larger soybean seeds out of the screening hole 14 to prevent it from blocking the screening hole 14 and improve the screening effect of the soybean seeds.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, the closing plate 8 is made of a transparent material. The closing plate 8 is made of a PC material. The PC board has high transparency, which is convenient for the staff to more intuitively view the screening situation of the soybean seeds inside the screening ring 3 and timely adjust the position of the blocking plate 9. And the PC board has the characteristic of sound insulation. When the soybean seeds are continuously stirred inside the screening ring 3, the PC board can reduce the sound generated by the collision between the soybean seeds and the inside of the screening ring 3.

[0030] During actual use, several screening holes 14 of the through-hole group are blocked by the blocking plate 9. When it is necessary to screen soybeans, the blocking plate 9 is moved to move in the fixed groove 11 at the bottom of the screening ring 3, and the blocking plate 9 unblocks several screening holes 14. The soybean seeds fall into the collection cavity in the collection box 1 through several screening holes 14. The soybean seeds are screened through the screening holes 14 with different aperture sizes in several through-hole groups, so that the soybean seeds are screened into the collection cavity of the collection box 1 from small to large according to size, avoiding the soybean seeds with small aperture sizes from falling into the collection cavity through the screening holes 14 with large apertures, and preventing the mixing of soybean seeds of different sizes, thereby improving the screening effect of soybean seeds.
