Description
Technical Field
[0001] This utility model relates to the field of seed production, and in particular to a seed mixing device. Background Technology
[0002] In agricultural production, in order to improve the disease resistance of seeds and promote seed germination and growth, it is often necessary to treat seeds with pesticides. Seed treatment is the process of uniformly attaching pesticides, fertilizers and other agents to the surface of seeds, thereby meeting the needs of efficient and precise production in modern agriculture.
[0003] However, traditional pesticide mixing devices often use simple paddle-type mixing methods, which can easily lead to poor uniformity of seed and pesticide mixing. Some seeds may have too much pesticide, affecting germination and growth, while others may have too little, affecting the mixing effect and reducing seed quality and agricultural production efficiency. In addition, the mixing method of traditional pesticide mixing devices is usually static mixing. In this way, the movement range of seeds and pesticides is limited, resulting in a slow mixing process and low efficiency.
[0004] Therefore, in view of the fact that the traditional mixing device uses simple paddle stirring and static mixing, which easily leads to poor uniformity and low efficiency of seed and pesticide mixing and affects seed quality, a seed production mixing device can be designed. This device uses a spiral conveyor rod to realize the circulation and mixing of seeds and pesticides in the inner cylinder, which improves the uniformity of mixing. At the same time, it also allows the seeds and pesticides to be more fully mixed during the rotation process. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment: a seed production mixing device, including an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is fixedly connected to the outer cylinder 1 by a fixing rod 3. A surrounding plate 4 is provided at the lower end of the outer cylinder 1, and the surrounding plate 4 and the bottom of the outer cylinder 1 form a cavity. A first rotary motor 5 is provided in the cavity. The output shaft of the first rotary motor 5 is connected to a screw conveyor rod 6, which is located inside the inner cylinder 2. A feed pipe 7 is provided on the outer wall of the outer cylinder 1. The upper end of the outer cylinder 1 is detachable. The outer cylinder 1 is connected to a cover plate 8, with a handle 9 at the upper end and a cleaning component for cleaning chemical residue from the inner wall of the outer cylinder 1 at the lower end. A cabinet 10 is located at the lower end of the enclosure 4, with a through hole at the upper end. A rotating component is installed inside the cabinet 10, containing a turntable 11 adapted to the through hole. The turntable 11 is connected to the lower end of the enclosure 4. The outer cylinder 1 rotates via the rotating component. The outer cylinder 1 serves as the external support structure for the entire device, and its outer wall is... The device is equipped with a feed pipe 7 for adding seeds or pesticides. The inner cylinder 2 is fixedly connected to the outer cylinder 1 via a fixing rod 3. The inner cylinder 2 is the working space of the screw conveyor 6, providing a channel for the conveying and mixing of seeds and pesticides. The first rotary motor 5 is installed in the cavity and is the power source for conveying seeds and pesticides in the entire device. The screw conveyor 6 is located inside the inner cylinder 2 and rotates under the drive of the first rotary motor 5. When the screw conveyor 6 rotates, the seeds and pesticides at the bottom are lifted vertically upward along the inner cylinder 2 and thrown out of the inner cylinder 2 opening. At the same time, due to the obstruction of the cover plate 8, the seeds and pesticides fall back into the outer cylinder 1 by gravity, thus forming a cycle. The lower end of the cover plate 8 is equipped with a cleaning component for cleaning pesticide residues on the inner wall of the outer cylinder 1 and keeping the inside of the outer cylinder 1 clean. The rotating component drives the turntable 11 to rotate, which in turn drives the surrounding plate 4 connected to the turntable 11 and the outer cylinder 1 to rotate together, so that the seeds and pesticides in the device are more fully mixed during the rotation process.
[0021] Please see Figure 1 and Figure 5In this embodiment, the cleaning component includes a hydraulic cylinder 12. The hydraulic cylinder 12 is symmetrically arranged at the lower end of the cover plate 8. The power output end of the hydraulic cylinder 12 is provided with an annular lifting plate 13. The side end of the lifting plate 13 is provided with cleaning teeth 14 for cleaning drug residues. The hydraulic cylinder 12 drives the lifting plate 13 to reciprocate. The hydraulic cylinder 12 is symmetrically installed at the lower end of the cover plate 8 and serves as the power source of the cleaning component. It drives the lifting plate 13 to perform vertical reciprocating motion through the hydraulic system. The lifting plate 13 has an annular structure and its diameter matches the inner wall of the outer cylinder 1, ensuring that the cleaning teeth 14 fit tightly against the cylinder wall. Under the drive of the hydraulic cylinder 12, it moves up and down along the axial direction of the outer cylinder 1 to achieve cleaning. The cleaning teeth 14 are made of elastic rubber or polyurethane material and are arranged in a serrated shape on the side end of the lifting plate 13. They can scrape off hard residues and flexibly clean sticky drugs. When the lifting plate 13 moves down, the cleaning teeth 14 contact the cylinder wall with a certain pressure and peel off the residue through reciprocating friction and shearing action.
[0022] Please see Figure 1 and Figure 4 In this embodiment, a second rotary motor 15 is installed inside the cabinet 10. The output shaft of the second rotary motor 15 is connected to a transmission shaft 16. The rotating assembly includes a bearing seat 17. A bearing seat 17 is installed at the bottom of the cabinet 10. A support shaft 18 is rotatably connected inside the bearing seat 17. The upper end of the support shaft 18 is fixedly connected to the lower end of the turntable 11. A transmission structure is provided between the support shaft 18 and the transmission shaft 16. The transmission structure includes a driving bevel gear 19. The driving bevel gear 19 is fixedly connected to the outer wall of the transmission shaft 16. A driven bevel gear 20 is fixedly connected to the outer wall of the support shaft 18. The driving bevel gear 19 and the driven bevel gear 20 are meshed together. A feed frame 21 is provided at the bottom of the outer cylinder 1. Seeds and pesticides pass through the feed frame. The frame 21 enters the inner cylinder 2. The cabinet 10 is equipped with a second rotary motor 15, which serves as the power source for the entire transmission system. The bearing seat 17 provides a stable and low-friction support point. The support shaft 18 is precisely installed inside the bearing seat 17, so that the turntable 11 can rotate with the rotation of the support shaft 18. The driving bevel gear 19 is fixedly installed on the outer wall of the transmission shaft 16, while the driven bevel gear 20 is fixedly installed on the outer wall of the support shaft 18. This bevel gear design can achieve a 90-degree power conversion, so that the transmission shaft 16 drives the support shaft 18 to rotate. The function of the feed frame 21 is to serve as a channel for seeds and pesticides to enter the inner cylinder 2, ensuring that the seeds and pesticides can fall into the inner cylinder 2 smoothly and evenly.
[0023] In the workflow, seeds and pesticides are first added to the outer cylinder 1 through the feed pipe 7. Then, the first rotary motor 5 and the second rotary motor 15 are started simultaneously. The first rotary motor 5 drives the screw conveyor 6 to start rotating. During this process, the screw conveyor 6 lifts the seeds and pesticides at the bottom along the inner cylinder 2 and throws them out of the inner cylinder 2 opening. Due to the blocking effect of the cover plate 8, the seeds and pesticides fall back into the outer cylinder 1 under the influence of gravity, forming a cycle of mixing. At the same time, the second rotary motor 15 drives the transmission shaft 16 to rotate, which in turn drives the active bevel gear 19 to rotate. This action drives the driven bevel gear 20 to rotate, ultimately causing the support shaft 18 and the turntable 11 on it to rotate together. This step further enhances the mixing effect of seeds and pesticides. When it is necessary to clean the outer cylinder 1, simply start the hydraulic cylinder 12. The hydraulic cylinder 12 drives the lifting plate 13 to move up and down, and uses the cleaning teeth 14 on the lifting plate 13 to scrape the pesticide residue on the inner wall of the outer cylinder 1.
[0024] Through the above steps, compared with the traditional mixing method, this solution uses a spiral conveyor rod 6 to realize the circulation and mixing of seeds and pesticides in the inner cylinder 2, which improves the uniformity of mixing. At the same time, the cleaning component designed at the lower end of the cover plate 8, with the help of the lifting plate 13 driven by the hydraulic cylinder 12 and the cleaning teeth 14, can efficiently remove the pesticide residue on the inner wall of the outer cylinder 1, ensuring the cleanliness of the device. Meanwhile, through the operation of the rotating component, the seeds and pesticides are more fully mixed during the rotation process. Compared with the static mixing method, this method has improved in terms of mixing efficiency and uniformity, solving the problem that the traditional mixing device uses simple paddle stirring and static mixing method, which easily leads to poor uniformity and low efficiency of seed and pesticide mixing, affecting seed quality.
[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
