Abstract
Description
Technical Field
[0001] This utility model relates to the field of peanut seed breeding grading and screening technology, specifically a peanut seed particle size screening machine. Background Technology
[0002] Peanut seeds, as the name suggests, are peanut kernels. Currently, peanut planting requires the use of a particle size screening machine to screen peanut seeds in order to obtain large and plump peanut seeds, thereby increasing the probability of harvesting high-quality peanuts.
[0003] An investigation revealed that a Chinese utility model patent discloses a peanut seed screening device (publication number: CN215940570U), comprising a shell, a feed inlet welded to the top of the shell, an oblique opening on the left side, and a connecting plate welded to the middle of the shell, a dust outlet welded below the oblique opening, a cover plate installed on the oblique opening, a motor installed on the right side of the shell, a fan blade installed at the output end of the motor, a first filter plate and a second filter plate installed on the right side of the connecting plate, a third filter plate and a fourth filter plate installed on the left side of the connecting plate, each of the first, second, third, and fourth filter plates having a mounting platform, a vibration motor installed at the bottom of each of the first, second, third, and fourth filter plates, a screw connected inside the mounting platform, a spring sleeved on the screw, and the screw installed inside the shell.
[0004] Although the aforementioned patent, compared to existing technologies, uses wind to separate unripe seeds and remove dust without damaging the peanut seeds, it can effectively screen peanuts of different diameters and collect them quickly. However, it still has the problem of not being able to clean the filter holes on the filter plate. This causes some peanut seeds to get stuck in the filter holes during the screening process, affecting the screening effect. As a result, manual cleaning of the peanut seeds in the filter holes on the filter plate is required from time to time, which inevitably generates a certain amount of manual labor and the cleaning process is cumbersome.
[0005] Therefore, this utility model provides a peanut seed particle size screening machine to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects
[0017] This invention, through the arrangement of a large particle box, filter holes, and unblocking blocks, allows the second pressing block to be repeatedly squeezed by the motor when the second pressing block rotates. This squeezes the second force block, causing it to drive the connecting shell and vibrate the large particle box via the first telescopic rod and the first spring. This causes smaller peanut seeds inside the large particle box to fall into the small particle box. Furthermore, the filter holes in the sealing plate at the bottom of the large particle box repeatedly contact multiple unblocking blocks for cleaning. This device effectively cleans the filter holes, preventing some peanut seeds from getting stuck and affecting the screening effect. Therefore, manual cleaning of the peanut seeds inside the filter holes is unnecessary, thus reducing labor costs. Attached Figure Description

[0025] 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.
[0026] This utility model provides a peanut seed particle size screening machine, such as... Figure 1-5 As shown, the particle size screening machine includes a base 1, a first telescopic rod 2 fixedly connected to the inner wall of the base 1, a connecting shell 3 fixedly connected to the end of the first telescopic rod 2 away from the base 1, a first spring 4 fixedly connected to the inner wall of the base 1, the end of the first spring 4 away from the base 1 fixedly connected to the outer wall of the connecting shell 3, the first telescopic rod 2 passing through the inner ring of the first spring 4, a large particle box 5 is provided inside the connecting shell 3, a small particle box 6 is fixedly connected below the large particle box 5, sealing doors 7 are hinged to the bottom of both the large particle box 5 and the small particle box 6, a filter hole 8 is opened inside the sealing door 7 at the bottom of the large particle box 5, a second force block 11 is fixedly connected to the outer wall of the connecting shell 3, a second extrusion block 12 for extruding the second force block 11 is rotatably connected inside the connecting shell 3, and a cleaning mechanism is provided inside the connecting shell 3.
[0027] Specifically, when the second pressing block 12 rotates, it repeatedly contacts and presses the second force-bearing block 11. This pressing of the second force-bearing block 11 drives the connecting shell 3, and the elastic cooperation between the first telescopic rod 2 and the first spring 4 causes vibration. This causes the connecting shell 3 to drive the large particle box 5 to vibrate, allowing smaller peanut seeds in the large particle box 5 to pass through the filter holes 8 and be screened into the small particle box 6. This achieves the purpose of particle size screening of peanut seeds, obtaining large and plump peanut seeds and increasing the probability of harvesting high-quality peanuts.
[0028] The cleaning mechanism includes a first extrusion block 10 rotatably connected inside the connecting housing 3, a first force-bearing block 9 fixedly connected to the outer wall of the large particle box 5 and in contact with the first extrusion block 10, a transmission belt 13 drivingly connecting the second extrusion block 12 and the first extrusion block 10, and a motor 14 for driving the second extrusion block 12 to rotate is provided inside the connecting housing 3.
[0029] The bottom of the inner wall of the connecting shell 3 is fixedly connected to the second telescopic rod 15, and the end of the second telescopic rod 15 away from the connecting shell 3 is fixedly connected to the outer wall of the small particle box 6.
[0030] A second spring 16 is fixedly connected to the bottom of the inner wall of the connecting shell 3. The end of the second spring 16 away from the connecting shell 3 is fixedly connected to the outer wall of the small particle box 6. The second telescopic rod 15 is inserted through the inner ring of the second spring 16.
[0031] A connecting plate 17 is fixedly connected to the inner wall of the connecting housing 3, and a plurality of unblocking blocks 18 for cleaning the filter holes 8 are fixedly connected to the top of the connecting plate 17.
[0032] The connecting plate 17 has multiple drop holes 19 inside, and a collection plate 20 is fixedly connected inside the connecting plate 17.
[0033] Specifically, the motor 14 enables the second pressing block 12 to rotate. When the motor 14 is running, the output shaft drives the second pressing block 12 to rotate and press the second force-bearing block 11, thus achieving particle size screening of the peanut seeds inside the large particle box 5. When the second pressing block 12 rotates, the transmission belt 13, which is coupled with it, drives the first pressing block 10 to rotate, causing the first pressing block 10 to repeatedly contact the first force-bearing block 9, thus moving the large particle box 5. Simultaneously, the small particle box 6, fixed to the large particle box 5, moves synchronously. The elastic cooperation between the second spring 16 and the second telescopic rod 15 enables the large particle box 5 to move up and down repeatedly. This allows the filter holes 8 inside the sealed door 7 at the bottom of the large particle box 5 to repeatedly contact the unblocking block 18, enabling the unblocking block 18 to clean the peanut seeds inside the filter holes 8. This prevents peanut seeds stuck in the filter holes 8 from affecting the screening effect. Furthermore, the drop hole 19 allows the small peanut seeds that have been screened to continue falling into the small particle box 6, preventing them from being blocked by the connecting plate 17 and remaining on the connecting plate 17, requiring manual collection. The collection plate 20 provides a blocking point for the more scattered small peanut seeds, preventing some small peanut seeds from falling to other locations. This ensures that all the screened small peanut seeds fall into the small particle box 6.
[0034] Both the outer walls of the large particle box 5 and the small particle box 6 are fixedly connected to a third spring 21, and the other end of the third spring 21 is fixedly connected to the outer wall of the sealing door 7.
[0035] Specifically, the third spring 21 provides elastic adjustment between the large particle box 5 and the sealing door 7, or between the small particle box 6 and the sealing door 7. When it is necessary to discharge and collect the peanut seeds in the large particle box 5 or the small particle box 6, the sealing door 7 can be moved to tilt and open a gap, allowing the peanut seeds inside to roll down for collection by the staff. Furthermore, during the screening process, the elastic force of the third spring 21 ensures that the sealing plate will not open arbitrarily, preventing peanut seeds from accidentally falling through the sealing door 7 during the screening process.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
