Description

Technical Field

[0001] This utility model relates to the field of agricultural seed cleaning equipment technology, and in particular to a wind-powered cleaning machine for broccoli seeds used in cultivation. Background Technology

[0002] In modern agricultural production, seed quality plays a decisive role in the growth, development, yield, and quality of crops. As an important vegetable crop, the cleaning and selection of broccoli seeds is particularly crucial. High-quality seeds not only improve germination and seedling survival rates but also reduce the occurrence of pests and diseases, laying the foundation for subsequent large-scale planting and high yields. Therefore, efficient and precise seed cleaning equipment is indispensable in agricultural production.

[0003] Currently, most broccoli seed cleaning equipment on the market uses a single fan structure for air-powered cleaning. This type of equipment suffers from low cleaning efficiency and unstable cleaning results in actual use. Because the airflow generated by a single fan is limited and unevenly distributed, it is difficult to accurately separate seeds with small weight differences from impurities, resulting in low purity of the cleaned seeds and affecting subsequent cultivation results. Furthermore, in terms of structural design, existing seed cleaning equipment often has a fixed, non-adjustable fan height, which cannot adapt to the cleaning needs of mixtures of seeds from different batches and in different states, resulting in poor flexibility. Regarding equipment storage, most equipment lacks a retractable storage structure, occupying a large space when idle, which is inconvenient for transportation and storage. Moreover, when collecting cleaned seeds, the storage device is inconvenient to install, exhibiting poor stability and being prone to shaking and falling off, affecting seed collection efficiency and the continuity of work. To address these problems, there is an urgent need to develop a new type of broccoli seed cleaning equipment that can improve cleaning efficiency and quality, enhance equipment flexibility and practicality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wind-powered cleaning machine for broccoli seeds. By rotating a knob, the screw, push box, and rotating rod can be coordinated to allow the device to unfold smoothly, facilitating the fixing of the collection bag to hold the seeds on the crossbar. The operation is simple and stable. At the same time, by utilizing components such as the fixed rod groove, sliding cover, and spring, the height of the upper fan can be flexibly fixed and adjusted to adapt to different cleaning needs, ensuring efficient and accurate cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wind-powered cleaning machine for broccoli seeds includes a ventilation pipe and a support. A lower fan is fixedly connected to the upper end of the support, and a control switch is fixedly connected to the front side of the support. A storage net is fixedly connected to the upper side of the lower fan, and a storage box is provided on the upper side of the storage net. A flip plate is slidably connected to the inside of the right side of the support, and a storage component is provided on the left side of the flip plate. A connecting pipe is fixedly connected to the upper side of the lower fan, and a fixing rod is fixedly connected inside the connecting pipe. A nut is fixedly connected to the lower outer wall of the fixing rod. An upper fan is provided on the upper outer wall of the fixing rod, and a fixing component is provided on the lower outer wall of the upper fan. The upper end of the upper fan is fixedly connected to the lower side of the ventilation pipe.

[0007] Furthermore, the fixing component includes a fixing shell fixedly connected to the lower outer wall of the upper fan, a sliding cover slidably connected to the outer wall of the fixing shell, a spring being provided inside the lower side of the sliding cover, and a hole being opened on the upper outer wall of the fixing shell, with a movable ball being provided inside the hole.

[0008] Furthermore, the storage assembly includes a second flap fixedly connected to the inside of the upper side of the support. A rotating rod is rotatably connected to the front side of the second flap, and a push box is rotatably connected to the front side of the rotating rod. A screw is threadedly connected inside the push box, a knob is fixedly connected to the right end of the screw, and a connecting block is threadedly connected to the left side of the screw.

[0009] Furthermore, a protrusion is fixedly connected to the upper side of the sliding cover, the protrusion is located outside the hole, a baffle is fixedly connected to the upper outer wall of the fixed shell, and the outer wall of the sliding cover is located below the baffle.

[0010] Furthermore, the spring is internally sleeved on the lower outer wall of the fixed shell, and the outer wall of the spring is located on the lower side of the protrusion.

[0011] Furthermore, a connecting rod is slidably connected to the upper side of the connecting block, and the other end of the connecting rod is fixedly connected to the inner wall of the second flap.

[0012] Furthermore, a fixing block is fixedly connected to the inner wall of the second flap, and a crossbar is fixedly connected inside the fixing block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, rotating the knob causes the screw to rotate the push box towards the center, which in turn causes the rotating rod to unfold outwards. The internal structure of the device is precisely matched to ensure a smooth and stable unfolding process. As the rotating rod rotates, the distance between the crossbar and the flap gradually increases, and under the transmission action, both sides of the device unfold simultaneously. At this time, the fully unfolded space inside the device provides great convenience for the installation of the storage bag. The positions of the crossbars on both inner walls are cleverly designed so that users can easily fix the storage bag on the crossbars to receive the cleaned seeds. This design is not only simple to operate, but also ensures that the storage bag is securely installed, avoiding shaking or falling off during the cleaning process, thus efficiently achieving seed collection and laying a good foundation for subsequent cleaning and storage operations.

[0015] 2. This utility model employs a clever and practical design for its cleaning machine. Multiple layers of circular grooves are formed on the outer wall of the fixed rod. The sliding cover on the outer wall of the fixed housing slides downwards, creating space for the moving ball. Then, the hole in the center of the fixed housing is aligned with the fixed rod and inserted. After insertion, the sliding cover is released. Under the elastic force of the spring, the protrusion on the sliding cover abuts against the moving ball, causing it to engage in the groove of the fixed rod, thus firmly fixing the upper fan. Because the outer wall of the fixed rod has multiple layers of circular grooves, users can flexibly adjust the height of the upper fan according to actual cleaning needs. Whether processing different types and states of seed mixtures or dealing with special cleaning scenarios, adjusting the fan height can optimize the cleaning effect, ensuring efficient and accurate cleaning.

[0022] 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.

[0023] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a wind-powered cleaning machine for broccoli seeds, including a ventilation pipe 1 and a support 11. A lower fan 10 is fixedly connected to the upper end of the support 11, and a control switch 12 is fixedly connected to the front side of the support 11. A storage net 9 is fixedly connected to the upper side of the lower fan 10, and a storage box 3 is provided on the upper side of the storage net 9. A flip plate 1 8 is slidably connected inside the right side of the support 11, and a flip plate 24 is provided to the left side of the flip plate 1 8. A rotating rod 15 is rotatably connected to the front side of the flip plate 24, and a push box 14 is rotatably connected to the front side of the rotating rod 15. A screw 17 is threadedly connected inside the push box 14, and a knob 13 is fixedly connected to the right end of the screw 17. A connecting block 16 is threadedly connected to the left side of the screw 17. A connecting pipe 7 is fixedly connected to the upper side of the lower fan 10. A fixing rod 4 is fixedly connected inside the connecting pipe 7. A nut 6 is fixedly connected to the lower outer wall of the fixing rod 4. An upper fan 2 is installed on the upper outer wall of the fixing rod 4. A fixing shell 5 is installed on the lower outer wall of the upper fan 2. A sliding cover 21 is slidably connected to the outer wall of the fixing shell 5. A spring 20 is installed on the lower side inside the sliding cover 21. A hole is opened on the upper outer wall of the fixing shell 5, and a movable ball 22 is installed inside the hole. The upper end of the upper fan 2 is fixedly connected to the lower side of the ventilation pipe 1.

[0024] Specifically, the cleaning machine adopts a dual-fan structure design. The mixture is placed inside the storage box 3. The upper fan 2 and the lower fan 10 are started by controlling the switch 12 and the wind speed is adjusted. When in use, the lower fan 10 blows upward, and the impurities inside will move upward. It will also cause the items inside the storage net 9 to tumble under the action of the wind, making the cleaning more thorough. The upper fan 2 on the upper side will also blow upward, thereby sucking away the impurities inside and expelling them from the right end of the ventilation pipe 1. The items left inside the storage box 3 are the desired products. Therefore, a fixing rod 4 is needed to fix the upper and lower sides. A structure was designed to fix the two fans. First, a circular groove is opened on the outer wall of the fixing rod 4. The sliding cover 21 on the outer wall of the fixing shell 5 is slid downwards, allowing the fixing rod 4 to be inserted through the hole in the middle of the fixing shell 5. After insertion, the sliding cover 21 can be released. Similarly, when disassembly is needed, the sliding cover 21 is slid downwards to easily separate the two parts. During this process, sliding the sliding cover 21 downwards provides space for the movement of the movable ball 22. When the fixing rod 4 is slid downwards and inserted, the movable ball 22 will move to one side. Once fully inserted, the sliding cover 21 can be released. A spring 20 is provided on the lower side of block 23, and a baffle is provided on the upper side of sliding cover 21. Therefore, sliding cover 21 will be pushed to the appropriate position, and the internal protrusion 23 will stay at the same level as the movable ball 22. The outer wall of fixing rod 4 has a circular groove, so the protrusion 23 abuts against one side, and the movable ball 22 will be restricted in the groove of fixing rod 4. The hole inside fixing shell 5 is slightly larger than the movable ball 22, but it will not allow the movable ball 22 to come out. When separated, similarly, sliding cover 21 downward will move the movable ball 22 to the side, and fixing rod 4 can move upward. In addition, the outer wall of fixing rod 4 has multiple layers of circular grooves, which can be used to fix the height of the device at will. Because the product of the device is a small product such as seeds, a retractable storage design was adopted, which can be retracted into the support 11 without taking up space. Rotating the knob 13 will move the screw 17 inside to the left, which will cause the push box 14 (the push box 14 is a rectangular box with a threaded hole inside, used to receive the thrust of the screw 17 and drive the rotating rod 15 to rotate) to rotate in the middle, thereby driving the rotating rods 15 on both sides to rotate outward, which will cause the entire device to unfold outward. The rotating rod 15 is designed with four sections, which can maintain the stability of the device well. After the rotating rod 15 rotates, the distance between the crossbar 18 and the flip plate 8 will expand, and the connecting rod 19 slides inside the connecting block 16. After one end unfolds, the other end can unfold in the same way under the action of transmission after the flip plate 24 and the flip plate 8 unfold, which can stably unfold the device. Thus, the storage bags and other items can be fixed on the crossbar 18 on both inner walls for collection. During this process, the self-locking characteristic of the device's threads prevents the device from springing back.

[0025] Reference Figure 2A protrusion 23 is fixedly connected to the upper side of the sliding cover 21, and the protrusion 23 is located outside the hole. A baffle is fixedly connected to the upper outer wall of the fixed shell 5, and the outer wall of the sliding cover 21 is located below the baffle. The spring 20 is internally sleeved on the lower outer wall of the fixed shell 5, and the outer wall of the spring 20 is located below the protrusion 23. A connecting rod 19 is slidably connected to the upper interior of the connecting block 16, and the other end of the connecting rod 19 is fixedly connected to the inner wall of the second flap 24. A fixing block is fixedly connected to the inner wall of the second flap 24, and a crossbar 18 is fixedly connected inside the fixing block.

[0026] Specifically, a protrusion 23 is fixedly connected to the upper side of the sliding cover 21. The protrusion 23 is located outside the hole, while a baffle fixedly connected to the upper outer wall of the fixed shell 5 restricts the outer wall of the sliding cover 21 to the lower side of the baffle. The spring 20 is internally sleeved on the lower outer wall of the fixed shell 5, and its outer wall is located below the protrusion 23, forming a linkage limiting structure: when the sliding cover 21 is slid down, the spring 20 is compressed. After being released, the force of the spring 20 will push the sliding cover 21 back to its original position, causing the protrusion 23 to lock the movable ball 22, thereby locking the fixed shell 5 and the fixed rod 4. A connecting rod 19 is slidably connected inside the upper side of the connecting block 16. The other end of the connecting rod 19 is fixedly connected to the inner wall of the second flip plate 24. When the knob 13 is rotated to drive the screw 17 to push the push box 14 to move, the rotating rod 15 will drive the connecting rod 19 to slide in the connecting block 16, thereby pushing the second flip plate 24 and the first flip plate 8 to unfold synchronously. The crossbar 18, which is fixedly connected inside the inner wall fixing block of the second flap 24, forms a symmetrical support structure with the crossbar 18 inside the inner wall of the first flap 8 after unfolding. This structure is used to fix the storage bag. The stable design of the four-section rotating rod 15, combined with the threaded self-locking characteristic, can prevent the device from springing back when it is in the storage state.

[0027] Working principle: The fan is fixed and adjusted using components such as a fixing rod 4, a fixing shell 5, a sliding cover 21, a spring 20, and a movable ball 22. A circular groove is formed on the outer wall of the fixing rod 4. The sliding cover 21 on the outer wall of the fixing shell 5 is slid downwards, allowing the movable ball 22 room to move. The hole in the middle of the fixing shell 5 is aligned with the fixing rod 4 and inserted. After insertion, the sliding cover 21 is released. Under the action of the spring 20, the protrusion 23 on the sliding cover 21 abuts against the movable ball 22, causing it to engage with the circular groove of the fixing rod 4, thus fixing the upper fan 2. Because the outer wall of the fixing rod 4 has multiple circular grooves, the height of the upper fan 2 can be adjusted to meet different cleaning needs. For disassembly, the sliding cover 21 is slid downwards again, causing the movable ball 22 to move, thus separating the upper fan 2 from the fixing rod 4.

[0028] The storage function is achieved through components such as knob 13, screw 17, push box 14, and rotating rod 15. When the device needs to be unfolded, rotating knob 13 moves screw 17 to the left, causing push box 14 to rotate towards the center, which in turn causes rotating rod 15 to rotate outward. Rotating rod 15 is designed with four sections to ensure the stability of the device when unfolded. As rotating rod 15 rotates, the distance between crossbar 18 and flap 8 increases, and connecting rod 19 slides within connecting block 16. Under the transmission action, both sides of the device unfold synchronously. After unfolding, storage bags can be fixed on the crossbar 18 on the inner walls of both sides for collecting cleaned seeds. The self-locking characteristic of screw 17's thread prevents the device from springing back during use, ensuring the stability of the storage structure. When not in use, rotating knob 13 in the opposite direction retracts the device into the support 11, saving space.

[0029] 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.
