Description

Technical Field

[0001] This utility model belongs to the field of seed screening technology, specifically referring to an adjustable speed seed air separator. Background Technology

[0002] In the fields of agricultural production and seed processing, seed sorting is a key step in ensuring seed quality and improving planting efficiency. Among them, wind sorting, a sorting method based on differences in seed density and weight, is widely used due to its ease of operation and low cost.

[0003] However, the existing seed air separation equipment has a small number of collection ports and a scattered layout, making it difficult to accurately match the falling trajectory of seeds under the action of wind. When seeds fall from the material discharge structure and are affected by the wind, seeds with different characteristics should be separated due to different falling distances. However, due to the unreasonable setting of the collection ports, seeds of multiple grades often fall into the same collection area, which fails to achieve the purpose of effective sorting. Utility Model Content

[0004] To solve the above problems, this utility model provides an adjustable speed seed air separator with a fan pitch adjustment function and multiple sets of horizontally arranged collection ports, so that seeds with different characteristics fall to different collection ports under the action of wind, significantly improving the sorting accuracy.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: An adjustable speed seed air separator includes a support plate, with multiple sets of support legs evenly arranged under the support plate. A support column is provided on one side of the support plate, and a hopper is provided at the top of the support column. A support seat is provided on the support plate, and a hinge shaft is provided inside the support seat. A fan is fixedly installed on the hinge shaft. The fan can adjust its pitch by rotating the hinge shaft. The fan performs air separation on the seeds conveyed and discharged from the hopper. A collection port is provided through the support plate, with multiple sets of collection ports evenly arranged and arranged laterally along the support plate. Seeds of different densities and weights fall at different distances when exposed to wind, thus falling into different collection hoppers to achieve the purpose of seed separation.

[0006] As a preferred embodiment of this utility model, the hopper is inclined toward the collection port, and the bottom of the hopper is provided with a discharge port.

[0007] As a preferred technical solution of this utility model, the support plate is provided with side baffles on both the front and rear sides, and a front baffle is provided on the other side of the support plate. The front baffle is connected to the two sets of side baffles to form a three-sided enclosure to protect the top opening of the material collection port.

[0008] As a preferred technical solution of this utility model, a turntable is rotatably passed through the side wall of the support. The turntable is connected to the hinge shaft, and a crank handle is provided on the turntable. The turntable can be rotated by the crank handle, thereby driving the fan on the hinge shaft to rotate and adjust the pitch.

[0009] As a preferred technical solution of this utility model, the turntable is provided with positioning holes, and multiple sets of positioning holes are evenly distributed on the turntable in a circular array. A positioning plate is rotatably provided on the outer side wall of the support, and a positioning rod is provided on the side end of the positioning plate. After adjusting the pitch of the fan, the positioning rod is inserted into the corresponding positioning hole to achieve positioning.

[0010] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0011] 1. The tilt angle of the blower can be adjusted by turning the turntable with the crank handle. The angle of the wind force can be flexibly adjusted according to the density and weight difference of the seeds. With multiple sets of horizontally arranged collection ports, seeds with different characteristics fall to different collection ports under the action of wind force, which significantly improves the sorting accuracy and adapts to the sorting needs of various seeds.

[0012] 2. With the help of the mechanical adjustment structure of the crank and turntable, the fan angle adjustment is simple and labor-saving. At the same time, the positioning method of inserting the positioning rod into the corresponding positioning hole can firmly fix the fan angle after adjustment, avoiding angle deviation caused by equipment vibration, and ensuring the stability and consistency of the sorting process.

[0013] 3. The hopper is designed to be inclined towards the collection port. Combined with the bottom discharge port, it can guide the seeds to fall naturally and continuously, avoiding the accumulation and blockage problems caused by traditional vertical discharge, and ensuring continuous and efficient air separation process.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, this utility model provides an adjustable speed seed air separator, including a support plate 1, with multiple sets of support legs 2 evenly arranged under the support plate 1, a pillar 3 on one side of the support plate 1, a hopper 4 at the top of the pillar 3, and a discharge port 9 at the bottom of the hopper 4. A support 5 is provided on the support plate 1, and a hinge shaft 6 is provided inside the support 5. A fan 7 is fixedly installed on the hinge shaft 6. The fan 7 can adjust its pitch by rotating the hinge shaft 6. The fan 7 performs air separation on the seeds conveyed and discharged from the hopper 4. A collection port 8 is provided through the support plate 1, with multiple sets of collection ports 8 evenly arranged and arranged laterally along the support plate 1. The hopper 4 is inclined towards the collection port 8. Seeds of different densities and weights fall at different distances when exposed to wind, thus falling into different collection ports to achieve the purpose of seed separation.

[0022] like Figures 1-3 As shown, side baffles 10 are provided on both the front and rear sides of the support plate 1, and a front baffle 11 is provided on the other side of the support plate 1. The front baffle 11 is connected to the two sets of side baffles 10 to form a three-sided enclosure to protect the top opening of the material collection port 8.

[0023] like Figures 1-4As shown, a turntable 12 is rotatably inserted through the side wall of the support 5. The turntable 12 is connected to the hinge shaft 6. A crank handle 13 is provided on the turntable 12. The turntable 12 can be rotated by the crank handle 13, thereby driving the fan 7 on the hinge shaft 6 to rotate and adjust the pitch. The turntable 12 is provided with positioning holes 14. Multiple sets of positioning holes 14 are evenly distributed in a ring array on the turntable 12. A positioning plate 15 is rotatably provided on the outer side wall of the support 5. A positioning rod 16 is retractably provided on the side end of the positioning plate 15. After adjusting the pitch of the fan 7, the positioning rod 16 is inserted into the corresponding positioning hole 14 to achieve positioning.

[0024] In practical use, based on the density and weight characteristics of the seeds to be sorted, rotate the handle 13 on the side wall of the support 5. The handle 13 drives the turntable 12 and the hinge shaft 6 to rotate, thereby adjusting the pitch of the fan 7. During the adjustment process, observe whether the angle of the fan 7 matches the expected falling trajectory of the seeds. When the angle of the fan 7 is adjusted to the appropriate position, rotate the positioning plate 15 on the outer wall of the support 5, so that the positioning rod 16 on the side of the positioning plate 15 is aligned with the corresponding positioning hole 14 on the turntable 12, and extend or retract the positioning rod 16. Insert the positioning hole 14 to fix the angle of the blower 7 and prevent the angle from shifting during use. Pour the seeds to be sorted into the hopper 4. The seeds slide down the inclined hopper 4 and fall continuously through the discharge port 9. Start the blower 7. The wind force acts on the falling seeds. Seeds of different densities and weights fall at different distances due to the different wind forces. They fall into different horizontally arranged collection ports 8 and enter the corresponding collection hoppers. After all the seeds in the hopper 4 have fallen and been sorted, turn off the blower 7.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
