[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0022] See also Figures 1-4 The present embodiment provides a wind-selected bamboo shavings screening device, comprising a box body 1, a feed trough 2 is passed through and fixedly connected on the top of the box body 1, a wind-selected component 3 is arranged on the right side of the box body 1, a screening component 4 is arranged on the inner surface of the box body 1, the screening component 4 comprises a partition 401, the partition 401 is fixedly connected to the inner surface of the box body 1, a support plate 402 is fixedly connected to the left side of the partition 401, a screen plate 404 is elastically connected to the top of the support plate 402 through a spring 403, the screen plate 404 is hinged to the left side of the inner surface of the box body 1, an opening is arranged on the left side of the box body 1 for the screen plate 404 to discharge bamboo fibers, the screening component 4 also comprises a plastic film 405, the plastic film 405 is fixedly connected between the screen plate 404 and the partition 401, and the plastic film 405 is used to seal the screen plate 404 and the partition 401. The gap between the sieve plate 404 and the partition plate 401 is prevented from falling from the gap between the sieve plate 404 and the partition plate 401 when the sieve plate 404 is shaken. A driving component 5 is arranged above the sieve plate 404, and the driving component 5 includes a support seat 501, which is fixedly connected to the back of the box body 1, and a motor 502 is fixedly connected above the support seat 501, and the output end of the motor 502 faces the front, and the output end of the motor 502 is fixedly connected to a rotating rod 503 through a coupling, and the rotating rod 503 penetrates the back of the box body 1 and is rotatably connected. A toggle block 504 is fixedly connected to the front end of the rotating rod 503, and the toggle block 504 is elliptical in shape, and the toggle block 504 is movably fitted with the top of the sieve plate 404, and a rotating component 6 is arranged above the partition plate 401, and a guide plate 7 is fixedly connected to the top of the inner surface of the box body 1, and the shape of the guide plate 7 is arc-shaped.

[0023] When the above-mentioned equipment is used, bamboo fiber is first thrown into the box body 1 from the feed trough 2, and the air selection component 3 will blow the bamboo fiber to the left, so that it passes through the partition 401 and falls on the screen plate 404. At this time, the motor 502 is started, and the motor 502 drives the rotating rod 503 to make the toggle block 504 rotate clockwise. As the toggle block 504 rotates, it will continuously push against the screen plate 404, and the screen plate 404 will reset under the action of the spring 403.

[0025] When the above-mentioned device is used, after the bamboo fiber is thrown into the box body 1 from the feed trough 2, the fan device 302 is started to blow air to the left through the air inlet bin 301. The blown wind will blow the lighter bamboo fiber to the left, and a part of the heavier bamboo fiber will be placed on the paddle 602. At this time, as the motor 502 drives the rotating rod 503 to rotate clockwise, it will also drive the transmission belt 603 to make the rotating shaft 601 rotate clockwise. The clockwise rotation of the rotating shaft 601 will drive the paddle 602 to poke the bamboo fiber blown over, and the lighter bamboo fiber will pass through the paddle 602, and the heavier bamboo fiber will be pushed down by the paddle 602 and fall into the collecting trough 8.
