The suction head 5 is fixedly connected to the front side of the main body 1 of the screening machine. The position of the suction head 5 corresponds to the position of the feed hopper 3. A vacuum cleaner 6 is placed on the top of the frame 2. The bottom of the suction head 5 is connected to the output end of the vacuum cleaner 6 by a thread.

[0020] By adopting the above solution, by setting up a vacuum cleaner 6 and a suction head 5, dust and light impurities generated during the grain screening process can be effectively removed, thereby significantly improving the cleanliness and quality of the final product.

[0021] refer to Figure 3 The bottom of the frame 2 is fixedly connected to the limiting frame 7. The shape of the bottom of the limiting frame 7 corresponds to the shape of the bottom of the vacuum cleaner 6. Two sliding grooves 8 are opened on the top of the frame 2. A fixed frame 9 is placed on the top of the frame 2. The front and rear sides of the bottom of the fixed frame 9 are slidably connected to the inside of the sliding grooves 8. The fixed frame 9 and the limiting frame 7 are used in conjunction with each other.

[0022] By adopting the above solution, the vacuum cleaner 6 can be stably installed and easily adjusted by setting the fixed frame 9 and the limiting frame 7. At the same time, the stability and reliability of the equipment during operation are further enhanced by the combined use of the fixed frame 9 and the limiting frame 7.

[0023] refer to Figure 4 A receiving block 10 is fixedly connected to the front side of the frame 2. A receiving groove 11 is opened inside the receiving block 10. A spring 12 is fixedly connected to the front side of the receiving groove 11. A connecting plate 13 is fixedly connected to the rear side of the spring 12. A fixing rod 14 is fixedly connected to the rear side of the connecting plate 13. The rear end of the fixing rod 14 passes through and extends into the interior of the slide groove 8. A fixing hole 15 is opened on the front side of the bottom of the fixing frame 9. The fixing hole 15 and the fixing rod 14 are used in conjunction with each other.

[0024] By adopting the above solution, the installation and disassembly of the vacuum cleaner 6 can be improved by setting the fixing rod 14 and the spring 12, and the stability and consistency of the equipment during operation can be ensured, which facilitates maintenance and cleaning work, thereby reducing downtime and improving overall work efficiency.

[0025] refer to Figure 4 A pull rod 16 is fixedly connected to the front side of the connecting plate 13, and the front end of the pull rod 16 passes through and extends out of the front side of the receiving block 10.

[0026] The above solution allows operators to easily unlock the locking mechanism by setting up a pull rod 16, greatly simplifying the disassembly and maintenance process of the vacuum cleaner 6.

[0027] refer to Figure 4Stabilizing rods 18 are placed on both the left and right sides inside the receiving groove 11. The front and rear ends of the stabilizing rods 18 are fixedly connected to the surface of the receiving groove 11. The left and right sides of the connecting plate 13 are slidably connected to the surface of the stabilizing rods 18.

[0028] By adopting the above solution, the stability bar 18 can effectively prevent the connecting plate 13 from shifting or jamming during operation, ensuring smooth execution of locking and unlocking actions.

[0029] refer to Figure 1 and Figure 2 A fan 19 is fixedly connected to the rear side of the top of the frame 2. An exhaust pipe 20 is fixedly connected to the output end of the fan 19. The other end of the exhaust pipe 20 is fixedly connected to the rear side of the top of the screening machine body 1. The position of the exhaust pipe 20 corresponds to the position of the feed hopper 3.

[0030] By adopting the above solution, by setting up the fan 19, the grain entering the screening machine body 1 can be cleaned by airflow in real time, effectively separating light impurities and dust, and significantly improving screening efficiency and the cleanliness of the final product.

[0031] The working principle of this utility model: In operation, first, start the blower 19 and the vacuum cleaner 6. Then, add the grain to be screened to the top of the screening machine body 1 through the feed hopper 3. As the grain falls into the screening machine body 1, the airflow generated by the blower 19 is guided to the grain through the exhaust pipe 20, effectively blowing away lighter impurities and dust. These blown-up dust and light impurities are guided to the location of the suction head 5 and collected by the vacuum cleaner 6. In this way, while the grain completes the initial screening, dust and impurities are also removed simultaneously, ensuring... To ensure the cleanliness and quality of the final product, after the screening work is completed, the vacuum cleaner 6 can be disassembled for cleaning. During disassembly, first pull the lever 16. The lever 16 moves the connecting plate 13 forward, and the connecting plate 13 moves the fixing rod 14 forward. After the fixing rod 14 moves out of the fixing hole 15, the fixing frame 9 can be moved along the slide 8. After the fixing frame 9 is moved away, the locking state of the vacuum cleaner 6 is released. After disconnecting the vacuum cleaner 6 from the nozzle 5, the vacuum cleaner 6 can be removed for subsequent maintenance.

[0032] In summary, this grain screening device, employing a surface cleaning structure, solves the problem that existing equipment often lacks an effective dust and light impurity removal mechanism during grain screening, resulting in the final product's cleanliness failing to meet high standards. This not only affects grain quality but also leads to poor air quality in the working environment, posing a threat to the health of operators. The device utilizes a combination of a screening machine body 1, frame 2, feed hopper 3, discharge hopper 4, suction head 5, dust collector 6, limit frame 7, chute 8, fixing frame 9, receiving block 10, receiving groove 11, spring 12, connecting plate 13, fixing rod 14, fixing hole 15, pull rod 16, stabilizing rod 18, fan 19, and exhaust pipe 20.
