Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, and in particular to a coated seed quality screening machine. Background Technology

[0002] The main purpose of using a quality screening machine to screen coated seeds is to remove defective products generated by the coating process itself, as well as clumps of two or more seeds that have stuck together due to the coating.

[0003] The screening machine uses a vibrating motor to drive the screen to vibrate. During repeated vibration, the screen blocks coated seeds larger than the screen aperture diameter, allowing seeds smaller than the aperture diameter to pass through, thus achieving seed quality screening. However, the screen is usually a fixed structure with a fixed aperture diameter, making it impossible to fine-tune the aperture size. The screen needs to be replaced manually to accommodate coated seeds of different sizes, resulting in the quality screening machine only being able to use seeds of a single size, which is not conducive to improving the flexibility of the quality screening machine.

[0004] Therefore, this application provides a coated seed quality screening machine to meet the needs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating-type seed quality screening machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a coating-type seed quality screening machine, including a vibrating base, and further comprising: A screening assembly is placed on top of a vibrating base. The screening assembly includes a left screen frame disposed on top of the vibrating base. An upper support is disposed on the inner side of the left screen frame. A lower support is rotatably connected to the inner side of the left screen frame near the upper support. A flexible screen is fitted on both the upper support and the lower support. A limiting component is provided, which is placed on one side of the left screen frame and is used to limit the rotation path of the lower support. The limiting component includes a right screen frame disposed on one side of the left screen frame. Both the left and right screen frames are connected to an annular support plate at one end near the upper and lower supports. The lower support is slidably connected to the annular support plate.

[0007] Furthermore, the upper support and the lower support are mirror images of each other on the inner sides of the left and right screen frames.

[0008] The beneficial effects of adopting the above-mentioned further solution are: it helps to reduce the gap between the two flexible screens, prevents seeds from falling between the two flexible screens, and avoids clogging the screen holes.

[0009] Furthermore, a push plate is connected to the side of the lower support near the right screen frame, and a sliding groove is provided on the side of the right screen frame near the push plate, with the push plate slidably connected to the sliding groove.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to adjust the size of the screen hole, the push plate is pushed, the push plate rotates along the slide groove and drives the flexible screen to rotate through the lower support, which makes it easier to push the lower support to rotate from the outside, which is conducive to quickly adjusting the angle of the flexible screen.

[0011] Furthermore, the left screen frame, upper support, lower support, and right screen frame are all provided with threaded grooves arranged in a circular array along the axis.

[0012] The beneficial effect of adopting the above-mentioned further solution is that fixing the upper and lower supports inside the left and right screen frames ensures that the angle between the upper and lower supports is fixed, thus ensuring the stability of the screen hole size and preventing the screen hole from deviating due to vibration.

[0013] Furthermore, clamps are provided on the side of both the upper and lower supports near the flexible screen.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the flexible screen is sleeved on the upper and lower supports, and then the clamps are installed on the outside of the two supports to fix the flexible screen on the upper and lower supports, thereby preventing the screen from shifting or falling off during vibration.

[0015] Furthermore, connecting plates are connected to the adjacent sides of both the left and right screen frames.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the connecting plate is welded to both sides of the left and right screen frames, and nuts and bolts are installed on the connecting plate, which facilitates the stable connection between the left and right screen frames.

[0017] Furthermore, a guide plate is connected to the inner bottom of the left screen frame, and a discharge cylinder is connected to the outer bottom of the left screen frame.

[0018] The beneficial effects of adopting the above-mentioned further solution are: by installing the discharge cylinder and the guide plate, the screened seeds fall onto the guide plate at the bottom of the inner side of the left screen frame, flow along the inclined angle of the guide plate to the discharge cylinder, and are discharged from the discharge cylinder in a concentrated manner, thus avoiding residue accumulation at the bottom of the left screen frame.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model, through the setting of a screening component, after the upper and lower supports are installed inside the left screen frame, the screen holes of the two are initially aligned. By rotating the lower support, the two sets of screen holes gradually transition from an aligned state to an intersecting state, thereby adjusting the size of the overlapping area of ​​the screen holes and achieving fine adjustment of the screen hole size of the flexible screen. This allows for matching of coated seeds of different particle sizes, eliminating the need for manual replacement of the flexible screen to adapt to multiple seed specifications. This solves the problem that quality screening machines can only handle seeds of a single size, and improves the flexibility of equipment use. 2. This utility model, through the setting of a limiting component, has an annular support plate welded to the left and right screen frames, forming a sliding groove that adapts to the upper and lower supports. When the right screen frame is installed on the left screen frame, the larger diameter base plates of the upper and lower supports insert into the sliding groove. At this time, the annular support plate is precisely inserted between the two base plates, providing support for the upper and lower supports and limiting the rotation path of the lower support, ensuring its stability during rotation.

[0023] 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.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a coated seed quality screening machine, including a vibrating base 1, and further comprising: like Figures 1-3 As shown, the screening component 2 is placed on the top of the vibrating base 1. The screening component 2 includes a left screen frame 21 set on the top of the vibrating base 1. An upper support 22 is provided on the inner side of the left screen frame 21. A lower support 23 is rotatably connected to the inner side of the left screen frame 21 near the upper support 22. Flexible screens 24 are fitted on both the upper support 22 and the lower support 23. like Figure 2 and Figure 5 As shown, the limiting component 3 is placed on one side of the left screen frame 21 and is used to limit the rotation path of the lower support 23. The limiting component 3 includes a right screen frame 31 disposed on one side of the left screen frame 21. Annular support plates 32 are connected to the inner sides of both the left screen frame 21 and the right screen frame 31 near the end between the upper support 22 and the lower support 23. The lower support 23 is slidably connected to the annular support plates 32. By installing the upper support 22 and the lower support 23 inside the left screen frame 21, the screen holes on the upper support 22 and the lower support 23 are aligned with each other. By rotating the lower support 23, the screen holes on the upper support 22 and the lower support 23 gradually change from an aligned state to an intersecting state, thereby controlling the size of the overlap of the two sets of screen holes and realizing the fine adjustment of the screen hole size of the flexible screen 24 to match different particle sizes. The seed-based design solves the problem of having to manually replace the flexible screen 24 to accommodate coated seeds of different sizes, which previously limited the quality screening machine to a single seed size. This improves the flexibility of the quality screening machine. Furthermore, by welding the annular support plate 32 to the left and right screen frames 21, the annular support plate 32 and the left and right screen frames 21 cooperate to form a sliding groove that fits the upper support 22 and the lower support 23. When the right screen frame 31 is installed on the left screen frame 21, the larger diameter base plates on the upper support 22 and the lower support 23 are inserted into the sliding groove. At this time, the annular support plate 32 is inserted between the two base plates, thereby supporting the upper support 22 and the lower support 23 and limiting the rotation path of the lower support 23, ensuring the stability of the lower support 23 during rotation.

[0025] Furthermore, such as Figures 2-3 As shown, the upper support 22 and the lower support 23 are mirror images of each other on the inner sides of the left sieve frame 21 and the right sieve frame 31. By mirroring the two supports along the center line between the upper support 22 and the lower support 23, the two flexible screens 24 are brought close to each other, which helps to reduce the gap between the two flexible screens 24, prevents seeds from falling between the two flexible screens 24, and avoids clogging the sieve holes.

[0026] Furthermore, such as Figures 1-2As shown, a push plate 33 is connected to the side of the lower support 23 near the right screen frame 31. A sliding groove 34 is provided on the side of the right screen frame 31 near the push plate 33. The push plate 33 is slidably connected to the sliding groove 34. After the push plate 33 is welded to the outside of the lower support 23 and the right screen frame 31 is installed on the left screen frame 21, the push plate 33 is inserted into the inside of the sliding groove 34. When it is necessary to adjust the size of the screen hole, the push plate 33 is pushed. The push plate 33 rotates along the sliding groove 34 and drives the flexible screen 24 to rotate through the lower support 23. This makes it easy to push the lower support 23 to rotate from the outside, which is beneficial for quickly adjusting the angle of the flexible screen 24.

[0027] Furthermore, such as Figure 3 As shown, threaded grooves 25 are arranged in a circular array along the axis on the left screen frame 21, upper support 22, lower support 23 and right screen frame 31. By installing bolts inside the threaded grooves 25 and installing nuts on the bolts, the nuts cooperate with the bolts to fix the upper support 22 and lower support 23 to the inner side of the left screen frame 21 and right screen frame 31, so that the angle between the upper support 22 and lower support 23 is fixed, ensuring the stability of the screen hole size and preventing the screen hole from deviating due to vibration.

[0028] Furthermore, such as Figure 3 As shown, clamps 26 are provided on the side of the upper support 22 and the lower support 23 near the flexible screen 24. By fitting the flexible screen 24 onto the upper support 22 and the lower support 23, and then installing the clamps 26 on the outside of both, the flexible screen 24 is fixed on the upper support 22 and the lower support 23, thereby preventing the screen from shifting or falling off during vibration.

[0029] Furthermore, such as Figures 4-5 As shown, connecting plates 27 are connected to the sides of the left screen frame 21 and the right screen frame 31 that are close to each other. By welding the connecting plates 27 to both sides of the left screen frame 21 and the right screen frame 31, and installing nuts and bolts on the connecting plates 27, it is easy to stably connect the left screen frame 21 and the right screen frame 31.

[0030] Furthermore, such as Figure 4 As shown, a guide plate 29 is connected to the bottom inner side of the left screen frame 21, and a discharge cylinder 28 is connected to the outer bottom of the left screen frame 21. By installing the discharge cylinder 28 and the guide plate 29, the screened seeds fall onto the guide plate 29 at the bottom inner side of the left screen frame 21 and flow towards the discharge cylinder 28 along the inclined angle of the guide plate 29, and are discharged from the discharge cylinder 28 in a concentrated manner to avoid residue accumulation at the bottom of the left screen frame 21.

[0031] Working principle: such as Figures 1-5As shown, first, the left screen frame 21 is installed on the mounting bracket on the vibrating base 1. Two flexible screens 24 are then fitted onto the upper bracket 22 and lower bracket 23, and secured with clamps 26. The upper bracket 22 and lower bracket 23 are pushed into the sliding groove formed by the left screen frame 21 and the annular support plate 32, making them mirror images of each other, with the screen holes on the flexible screens 24 aligned. Then, the right screen frame 31 is placed on the left screen frame 21, and bolts and nuts are installed on the connecting plate 27, fixing the right screen frame 31 to the left screen frame 21. At this point, the annular support plate 32 supports the upper bracket 22 and lower bracket 23. Next, the push plate 33 is pushed, and the push plate 33 moves along the sliding groove 34 through the lower bracket 23. The flexible screen 24 at the bottom is rotated, thereby controlling the size of the overlapping area of ​​the two sets of screen holes according to the size of the seeds, and realizing fine adjustment of the size of the screen holes of the flexible screen 24. The bolts and nuts are installed on the threaded groove 25, so that the upper support 22 and the lower support 23 are fixed on the left screen frame 21 and the right screen frame 31, and the angle between the two flexible screens 24 is fixed. Finally, the vibration motor on the vibration base 1 is started, so that the left screen frame 21 vibrates and screens the seeds, so that the seeds of qualified size pass through the flexible screen 24, and then move along the guide plate 29 towards the discharge cylinder 28 and are discharged, thus realizing the screening of seeds. After screening, the unqualified seeds are removed by the external dust collection device.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
