Description

Technical Field

[0001] This utility model relates to the field of impurity removal equipment, and in particular to an agricultural breeding impurity removal device. Background Technology

[0002] In the field of agricultural breeding, seed purity directly affects crop yield and quality. Ensuring high seed purity is crucial for cultivating superior varieties. Traditional manual impurity removal methods are inefficient, labor-intensive, and prone to missed detections and misjudgments; while some early mechanical impurity removal equipment has limited functionality and cannot meet the high standards of seed purity required by modern breeding. Therefore, the development of a highly efficient, precise, and multifunctional agricultural breeding impurity removal device is urgently needed.

[0003] Currently, some agricultural breeding and impurity removal equipment suffers from problems such as complex structure, inconvenient operation, and difficult maintenance. Moreover, the efficiency and quality of impurity removal are difficult to guarantee, the adaptability to different types of seeds and impurities is poor, the energy consumption of the equipment is high, and the operating cost is large, which does not conform to the development trend of green and energy-saving agriculture in modern agriculture.

[0004] Therefore, we propose an agricultural technology breeding and impurity removal device. Utility Model Content

[0009] As a further improvement of this utility model: the top of the mounting support is provided with a feed port, and a connecting rod is fixedly provided at the top of the mounting support, the connecting rod and the mounting support forming an eccentric shaft structure.

[0010] As a further embodiment of this utility model: a second connecting rod is engaged at the top of the connecting rod, and the second connecting rod is engaged and connected with the first connecting rod.

[0011] As a further embodiment of this utility model: support legs are fixedly provided at the four corners of the bottom end of the separating frame, the discharge guide plate is engaged between the support legs, and the top of the discharge guide plate is inclined.

[0012] As a further embodiment of this utility model: the separating bucket is conical in side view and is threadedly connected to the mounting support; the filter bucket has a connecting thread at the center of its surface and is threadedly connected to the separating bucket by means of the connecting thread.

[0013] As a further embodiment of this utility model: the surface of the secondary impurity removal plate is provided with a plurality of filter holes, the secondary impurity removal plate is inclined and parallel to the filter bucket.

[0014] Compared with the prior art, this utility model provides an agricultural breeding and weed removal device, which has the following beneficial effects:

[0015] This invention features a conical separating hopper in side view, which is threadedly connected to the mounting support. This design facilitates disassembly and cleaning, improving the ease of equipment maintenance. The filter holes on the upper surface of the filter hopper and the steel filter screen on the lower surface enable preliminary screening of seeds and impurities, effectively separating particles of different sizes and shapes. The filter holes on the surface of the secondary impurity removal plate are parallel to and inclined to the filter hopper, further removing impurities from the pre-filtered seeds to ensure the purity of the output. This layered, multi-stage filtration structure significantly improves impurity removal efficiency and quality, meeting the stringent requirements of agricultural breeding technology for high seed purity.

[0016] In this invention, the drive motor on the drive plate drives the first connecting rod to rotate, and through the connecting rod of the eccentric shaft structure and the second connecting rod that is engaged with it, the power is transmitted to the mounting support, so that the mounting support generates a specific motion trajectory during the feeding process. The eccentric shaft transmission method enables the seeds to form a dynamic motion state in the separation hopper, avoids seed accumulation, and allows impurities to be fully separated from the seeds, thereby improving the impurity removal effect.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: An agricultural technology breeding and impurity removal device, such as Figures 1-4As shown, the system includes a separating frame 1, a suspension plate 2 fixedly mounted between the separating frames 1, a mounting support 3 engaged on the surface of the suspension plate 2, a separating hopper 4 movably mounted at the bottom of the mounting support 3, a filter hopper 5 movably mounted at the bottom of the separating hopper 4, a secondary impurity removal plate 6 fixedly mounted at the bottom of the separating frame 1, and a discharge guide plate 7 fixedly mounted at the bottom of the secondary impurity removal plate 6. The upper surface of the filter hopper 5 has several filter holes 8, and the lower surface of the filter hopper 5 is composed of a steel filter screen 9. A drive plate 10 is fixedly mounted on one side of the suspension plate 2, a drive motor 11 is fixedly mounted at the top of the drive plate 10, and a connecting rod 12 is fixedly mounted at the bottom of the drive motor 11. The drive motor 11 drives the connecting rod 12 to rotate. The separating hopper 4 is conical in side view and is threadedly connected to the mounting support 3. This design facilitates disassembly and cleaning, improving the convenience of equipment maintenance. The filter holes 8 on the upper surface of the filter hopper 5 and the steel filter screen 9 on the lower surface can achieve preliminary screening of seeds and impurities, effectively separating particles of different sizes and shapes.

[0026] like Figures 1-4 As shown, the top of the mounting support 3 has a feed inlet 13, and a connecting rod 14 is fixedly installed at the top of the mounting support 3. The connecting rod 14 and the mounting support 3 form an eccentric shaft structure. A second connecting rod 15 is engaged at the top of the connecting rod 14, and the second connecting rod 15 is engaged and connected with the first connecting rod 12. Support legs 16 are fixedly installed at the four corners of the bottom of the separating frame 1. The discharge guide plate 7 is engaged between the support legs 16, and the top of the discharge guide plate 7 is inclined. The drive motor 11 on the drive plate 10 drives the first connecting rod 12 to rotate. Through the eccentric shaft structure of the connecting rod 14 and the second connecting rod 15 engaged with it, the power is transmitted to the mounting support 3, so that the mounting support 3 generates a specific motion trajectory during the feeding process. This eccentric shaft transmission method enables the seeds to form a dynamic motion state in the separating hopper 4, avoiding seed accumulation, allowing impurities to be fully separated from the seeds, and improving the impurity removal effect.

[0027] like Figures 1-3 As shown, the separation bucket 4 is conical in side view and is threadedly connected to the mounting support 3. The filter bucket 5 has a connecting thread 17 at the center of its surface and is threadedly connected to the separation bucket 4 by means of the connecting thread 17. The secondary impurity removal plate 6 has several filter holes 18 on its surface. The secondary impurity removal plate 6 is inclined and parallel to the filter bucket 5.

[0028] Working Principle: Seeds to be impurities removed are poured into the feed inlet 13 of the mounting support 3. The drive motor 11 starts, causing the connecting rod 12 to rotate. Through the connecting rod 15 and the connecting rod 14 of the eccentric shaft structure, the mounting support 3 generates eccentric motion, which in turn causes the separation bucket 4 to shake. During the shaking of the separation bucket 4, the seeds and impurities begin to separate initially under the action of gravity and centrifugal force. Smaller impurities fall through the filter holes 8 on the upper surface of the filter bucket 5. Next, the seeds continue to move downwards and pass through the steel filter screen 9 on the lower surface of the filter bucket 5, where finer impurities are further separated. Subsequently, the seeds fall onto the secondary impurity removal plate 6, which is inclined and has filter holes 18 parallel to the filter bucket 5. Under the action of gravity, the seeds slide down the secondary impurity removal plate 6. During the slide, residual impurities are separated out through the filter holes 18. Finally, the pure seeds are discharged from the equipment through the discharge guide plate 7, completing the entire impurity removal process.

[0029] 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.
