It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a rice seed air separation device, including a screening chamber 1, a fan 6 installed on one side of the screening chamber 1, a discharge port 18 opened on the bottom surface of the screening chamber 1, a debris discharge port 19 opened on the bottom surface of the screening chamber 1 away from the discharge port 18, a collection box 4 installed below the debris discharge port 19, the collection box 4 being slidably connected to the bottom of the screening chamber 1 and fixed to the screening chamber 1 by a fixing component 5, the fixing component 5 including a block 501 and a fixing block 502, the fixing block 502 being fixedly connected to the screening chamber 1, and the block 501 having an insertion hole 503, the block 501 being fixedly connected to the collection box 4, and a fixing component being slidably connected inside the block 501. A rod 504 is fixed, with its top end inserted into a socket 503. A pull rod 505 is fixedly connected to the bottom end of the fixed rod 504, and a handle 507 is fixedly connected to the bottom end of the pull rod 505. A spring 506 is fitted onto the pull rod 505. A feeding frame 2 is fixedly connected to the top of the screening chamber 1, and a funnel 3 is fixedly connected to the top end of the feeding frame 2. An inclined guide plate 20 is provided below the discharge port 18. A slot 13 is opened on the side of the feeding frame 2, and a baffle 14 is inserted inside the slot 13. A support rod 15 is fixedly connected to the top of the screening chamber 1, and a screw 16 is threaded inside the support rod 15. One end of the screw 16 is rotatably connected to the end of the baffle 14, and a knob 17 is fixedly connected to the other end of the screw 16.

[0017] The beneficial effects achieved in this embodiment 1 are as follows: By setting a collection box 4 slidably connected to the screening chamber 1 below the debris discharge outlet 19, and using a fixing assembly 5 consisting of a block 501, a fixing block 502, a fixing rod 504, a pull rod 505, a handle 507, and a spring 506 to fix the collection box 4, when the air separation operation is performed, the debris and shriveled rice grains are blown out by the blower 6 and fall into the collection box 4 below through the debris discharge outlet 19, achieving centralized collection and preventing them from randomly scattering and affecting the working environment and the health of the workers. Moreover, when it is necessary to clean the collection box 4, it is only necessary to pull the handle 507. Hand 507 drives pull rod 505, which in turn pulls fixed rod 504 to disengage it from insertion hole 503, making it easy to pull out collection box 4 for cleaning, which is convenient to operate; by opening slot 13 on the side of feeding frame 2 and inserting baffle 14, and by using screw 16 threaded to support rod 15 to rotate one end to the end of baffle 14 and the other end to knob 17, rotating knob 17 drives screw 16 to rotate, which can make baffle 14 move in slot 13, thereby flexibly adjusting the opening size of feeding frame 2, making it easy to control the feeding speed of rice seeds, adapting to different wind separation operation needs, and ensuring wind separation effect.

[0018] Example 2: As Figure 3 - Figure 6 As shown, the bottom of the two side support legs of the screening chamber 1 is fixedly connected to a crossbar 7. The bottom surface of the crossbar 7 is fixedly connected to the two ends of the crossbar 7. The top surface of the two ends of the crossbar 7 is provided with threaded holes 8. The threaded holes 8 are connected to the screw rod 9. The top of the screw rod 9 is fixedly connected to a handwheel 11. The top of the screw rod 9 is provided with a rotatable foot 10. The outer wall of the handwheel 11 is fixedly connected to a handle sleeve 21. The handle sleeve 21 is made of elastic rubber. The ground of the foot 10 is evenly distributed with several anti-slip cones 22.

[0019] The beneficial effects achieved in this embodiment 2 are as follows: By setting movable wheels 12 on the crossbars 7 at the bottom of the support legs on both sides of the screening chamber 1, the entire rice seed air separation equipment can be moved easily, allowing it to be conveniently transferred to different work sites; by setting threaded holes 8 on the top surface of both ends of the crossbar 7, with threaded screws 9 connected to the threaded holes 8, and the top of the screws 9 connected to a handwheel 11 with an elastic rubber handle sleeve 21 and a rotatable foot 10 with an anti-slip cone 22 on the bottom surface, after the screening chamber 1 is moved to the designated position, the operator holds the handle sleeve 21. 1. Rotating the handwheel 11, the elastic rubber-supported handle sleeve 21 provides a comfortable grip and friction. When the handwheel 11 is rotated, it slips. The handwheel 11 drives the lead screw 9 to rotate in the threaded hole 8. The lead screw 9 pushes the foot 10 downward until the bottom surface of the foot 10 abuts against the ground. The anti-slip cone 22 increases the friction with the ground, which not only fixes the moving wheel 12 to prevent the screening chamber 1 from moving accidentally, but also levels the four corners of the screening chamber 1 to ensure that the equipment is in a stable state, which is conducive to the normal operation of the air separation and ensures the screening effect.

[0020] The working principle of this embodiment is as follows: When using the rice seed air separation equipment, the rice seeds are first poured into the funnel 3. The seeds enter the feeding frame 2 through the funnel 3. The knob 17 can be turned according to actual needs. The knob 17 drives the screw 16 to rotate, so that the baffle 14 connected to the screw 16 rotates and moves in the slot 13, thereby adjusting the opening size of the feeding frame 2 and controlling the speed at which the seeds enter the screening chamber 1. The seeds entering the screening chamber 1 are blown by the wind generated by the blower 6. Lighter impurities and shriveled rice grains are blown towards the impurity discharge outlet 19 and fall into the collection box 4 below, which is fixedly connected to the screening chamber 1 by the fixing component 5, for centralized collection. Heavier rice seeds that meet the requirements fall from the discharge port 18 on the bottom of the screening chamber 1 under the action of gravity and are guided to the corresponding collection point by the inclined guide plate 20 below the discharge port 18. When it is necessary to move the equipment, the moving wheels 12 at both ends of the bottom of the crossbar 7 are used to push the equipment to the designated location. After arriving, the operator turns the handwheel 11, which drives the lead screw 9 to rotate. The lead screw 9 pushes the foot 10 downward to contact the ground. The anti-slip cone 22 on the bottom of the foot 10 is used to fix the equipment and level it to ensure that the subsequent wind separation operation is stable. By repeating this operation, the wind separation of rice seeds can be achieved, and the equipment can be moved, fixed, and leveled.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
