[0027] Example 1:

[0028] Reference Figure 1-4 This embodiment provides a high-efficiency cleaning device for seed cultivation, including a fixed support 1, a seed conveyor belt 7, and a seed cleaning chamber 8. The fixed support 1 is welded from a stainless steel frame and coated with an anti-rust coating. The seed conveyor belt 7 is horizontally mounted above the fixed support 1 via bearing seats, with its right end extending to the inlet of the seed cleaning chamber 8 to form a 10° inclined feeding section. The drive motor 2 is bolted to the bottom crossbeam of the fixed support 1, and its output shaft is connected to the drive roller of the seed conveyor belt 7 via a pulley mechanism.

[0029] The seed conveyor belt 7 has outer protective plates 3 with a height of 50mm welded to both sides to prevent seeds from scattering. The surface of the conveyor belt has anti-slip embossing, and the belt speed is adjustable from 0.3 to 0.8 m / s. A miniature fan 5 is installed 300mm directly above the conveyor belt, and its air outlet extends to the right end of the conveyor belt through an output air duct 4. The end of the air duct has a flat opening, and the air outlet direction forms a 30° angle with the plane of the conveyor belt. The miniature fan 5 is surrounded by an aluminum alloy heat insulation cover 6, which is filled with ceramic fiber heat insulation material.

[0030] The seed washing chamber 8 is made of 304 stainless steel, with a trapezoidal feed inlet on its left side wall that connects to the conveyor belt. Inside the chamber, a cylindrical screening component 9 and a square spraying component 10 are coaxially mounted. The cylindrical screening component 9 includes an annular frame 201 driven by a primary output shaft 204. A seed annular screen 202 with a 2mm aperture is welded to the outer surface of the annular frame, and spiral guide strips 203 are welded to the outer wall of the screen, with a spacing of 50mm between the guide strips. The washing chamber 301 of the square spraying component 10 is driven to rotate by a secondary drive shaft 303. Eight independent spraying units 302 are evenly distributed around the circumference of the chamber, and each spraying unit is equipped with an adjustable-angle fan-shaped nozzle.

[0031] The seed washing chamber 8 has a screening slot 11 on its right side wall, which can accommodate replacement screens of different mesh sizes. A V-shaped guide channel is located at the bottom of the chamber, with a removable screening filter 104 installed at the bottom, connected below to a 20L impurity storage box. A drive positioning bracket 105 is welded to the outer wall of the chamber, and its positioning hole maintains a coaxiality error ≤0.1mm with the output shaft of the drive motor.

[0032] The specific working steps of this device are as follows:

[0033] 1. When the seeds fall into the washing chamber 8 from the right end of the conveyor belt 7, the miniature fan 5 blows away light impurities through the output air duct 4;

[0034] 2. Seeds enter the rotating cylindrical screening component 9, and the guide bar 203 drives the seeds to make a spiral motion. Qualified seeds fall into the washing area through the screen 202.

[0035] 3. The square spray component 10 rotates at a speed of 30 r / min, and the independent spray unit 302 sprays a cleaning solution with pH 6.5 at multiple angles;

[0036] 4. After washing, the seeds are filtered twice through the screening filter 104. Impurities fall into the storage box, and clean seeds are exported from the expansion plate 12.

[0037] Furthermore, the internal screening filter 104 of the device adopts a quick-release snap-fit ​​installation, allowing for rapid replacement of the 80-120 mesh filter, thereby improving the device's adaptability. The pressure of the independent spray unit 302 is adjustable from 0.2 to 0.5 MPa, allowing operators to change the pressure of the independent spray unit 302 according to different seed cleaning needs, thus adapting to seed cleaning tasks under different conditions. At the same time, the extension plate 12 on the right side of the seed cleaning chamber 8 has a telescopic structure with a maximum extension length of 500 mm. Operators can use the extension plate 12 to improve the device's adaptability and make actual operation more convenient.

[0038] This application can be widely used for large-scale cleaning of seeds such as wheat, rice, and corn, and is especially suitable for breeding laboratories and seed processing plants. By changing the screen and adjusting the spray parameters, it can also be adapted to the cleaning needs of small seeds such as vegetables and flowers.

[0039] 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.
