Description

Technical Field

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

[0002] With seed grading, screening, and cleaning as its core, this product covers the seed production field and solves the problem of low grading efficiency in the seed screening process, enabling efficient separation and classified collection of seeds of different specifications. At the same time, it solves the problem of severe dust pollution during screening operations by improving the working environment through dust collection and purification functions.

[0003] A search revealed existing technology (application number: CN216965289U), which describes "a sorting device for easy seed sieving." This utility model includes a sieving component and a driving component. The sieving component includes a base, a sliding frame, a screening frame group, a connecting column, and a snap-fit ​​component. The sliding frame is slidably disposed on the top of the base. The driving component includes a fixed frame, a motor, a rotating shaft, a cam, and an elastic element. The fixed frame is fixedly connected to the top of the base, the motor is disposed within the fixed frame, and the rotating shaft is rotatably disposed between the base and the output end of the motor.

[0004] However, while existing technologies can effectively screen seeds by using screening components to separate seeds of different sizes and improve seed quality, they still have some shortcomings: existing technologies do not take into account the problem of dust generated during seed screening. This device improves the working environment by using a dust collection component installed at the top. Utility Model Content

[0030] Example 1

[0031] like Figures 1 to 3As shown, this embodiment provides a seed production screening device, comprising: a support frame 1 for supporting components; a rotating component including a driving pulley 3 rotatably connected to the support frame 1 and a driven pulley 4 rotatably connected to the support frame 1; a reciprocating component including a fixed shaft 6 disposed on the driven pulley 4 and a filter box 8 slidably connected to the support frame 1; a multi-stage filtration component including a feed inlet 11 opened at the top of the support frame 1 and a filter screen 12 disposed at the upper end of the inside of the support frame 1; a collection component including a guide plate 14 disposed at the lowest point of the filter screen 12; and an auxiliary component including a dust suction hood 16 disposed on the support frame 1 and a fan 17 connected to the dust suction hood 16 via a pipe.

[0032] It should also be noted that the seeds mentioned in this application may be corn, wheat, vegetable seeds, etc. Figure 1 In this embodiment, corn is used as an example for description. Of course, other types of seeds can also adopt a similar structure, which will not be repeated hereafter.

[0033] Understandable, Figure 1 The diagram only schematically illustrates some of the components of the screening device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, screening devices can also include those that are more advanced than... Figure 1 More or fewer parts.

[0034] Furthermore, in this embodiment, the rotating component drives the reciprocating component to make the filter box 8 reciprocate. The multi-stage filtration component filters the seeds in stages, the collection component collects the seeds, and the auxiliary component removes dust. This achieves multi-stage seed sieving, improves sieving efficiency, and reduces dust pollution.

[0035] Specifically, the rotating assembly includes: a drive motor 2, which is arranged on the support frame 1 and whose output shaft is connected to the drive pulley 3; and a synchronous belt 5, which is connected to the drive pulley 3 and the driven pulley 4.

[0036] In this embodiment, the drive motor 2 drives the active pulley 3 to rotate, and the synchronous belt 5 drives the driven pulley 4 to rotate synchronously; thus providing power to the device and realizing rotational transmission.

[0037] Specifically, the reciprocating assembly includes: a connecting rod 7, one end of which is rotatably connected to a fixed shaft 6, and the other end of which is rotatably connected to a filter box 8; a roller 9, which is slidably connected to a support frame 1; and a connecting shaft 10, one end of which is connected to the filter box 8, and the other end of which is connected to the roller 9.

[0038] In a preferred embodiment, the driven pulley 4 rotates to make the fixed shaft 6 rotate, which drives the filter box 8 through the connecting rod 7, and the roller 9 slides on the slide rail to achieve reciprocating motion; making the filter box 8 slide back and forth enhances the screening effect.

[0039] Example 2

[0040] Specifically, the multi-stage filtration assembly includes: filter screen 2 13, which is disposed on the filter box 8 and located below filter screen 12.

[0041] In this embodiment, after the seeds are initially filtered by filter screen 12, smaller seeds fall into filter screen 13 for a second filtration; thus achieving two-stage sieving of the seeds and distinguishing qualified seeds.

[0042] Specifically, the collection component includes a collection box 15, which is arranged at the discharge port of the guide plate 14.

[0043] With this setup, the seeds on filter screen 12 flow into collection box 15 via guide plate 14, while the seeds on filter screen 2 13 fall directly into the corresponding collection box 15; seeds of different sizes are collected separately for easy classification.

[0044] Example 3

[0045] Specifically, the auxiliary component includes a filter screen 18, which is disposed in the middle of the pipe connecting the dust hood 16 and the fan 17.

[0046] When the fan 17 is started, the dust hood 16 absorbs the dust generated during screening, and the dust is intercepted by the filter screen 18 through the pipeline; thus removing the dust during the screening process and purifying the working environment.

[0047] Specifically, the filter screen 12 is made of stainless steel.

[0048] In actual use, the user adds seeds into the filter box 8 through the feed inlet 11, and then starts the drive motor 2 to drive the drive pulley 3 to rotate. The drive pulley 3 drives the driven pulley 4 to rotate through the synchronous belt 5. The driven pulley 4 drives the fixed shaft 6 to make a circular motion. The fixed shaft 6 drives the filter box 8 to slide on the support frame 1 through the rollers 9 on both sides via the connecting rod 7. At this time, the seeds added into the filter box 8 are filtered and separated through the filter screen 12 and the filter screen 2 13. At the same time as separation, the fan 17 is started to adsorb the dust generated inside onto the filter screen 3 18. The filter screen 3 18 can be pulled out to the outside by loosening the bolts for replacement or cleaning. The filter screen 12 is used to separate large impurities, and the filter screen 2 13 is used to remove small impurities and unqualified seeds. The filtered material enters the collection box 15 through the guide plate 14 to achieve classification.

[0049] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
