[0001] The utility model relates to the technical field of Astragalus seed screening, in particular to an energy-saving dust removal device for screening Astragalus seeds. Background Technique
[0002] Astragalus is a plant of the genus Astragalus in the legume family, also known as Astragalus membranaceus var. mongholicus, Astragalus membranaceus, etc. Astragalus has the effects of invigorating qi and ascending yang, consolidating superficial resistance to stop sweating, promoting diuresis and detumescence, promoting fluid production and nourishing blood, promoting qi circulation and dredging collaterals, expelling pus by supporting healthy qi, and astringing sores and promoting granulation.
[0003] Before the existing Astragalus is planted, the seeds of Astragalus need to be screened. During the screening process, the Astragalus seeds are poured onto the screening machine for screening. In the actual screening process, since the Astragalus seeds will vibrate on the screen, dust is likely to occur, and the dust will fly into the surrounding air, thus easily polluting the air. Therefore, we propose an energy-saving dust removal device for screening Astragalus seeds. Content of the Utility Model
[0004] The purpose of the utility model is to provide an energy-saving dust removal device for screening Astragalus seeds, which solves the problems mentioned in the background technique.

[0007] By adopting the above technical solution, the device is transferred to the vicinity of the sieve plate of the vibrating screen, and then the dust collection hood is placed above the mesh plate. Then, when the Astragalus seeds are screened by the vibrating screen, the Astragalus seeds will vibrate, resulting in dust. At this time, the exhaust fan is used to create negative pressure in the filter box, so that the dust can be sucked away by the dust collection hood, and the dust and impurities are sucked into the filter box for filtration, avoiding the occurrence of dust pollution to the surrounding air.
[0008] As a preferred implementation manner of the utility model, an arc-shaped filter mesh plate is fixedly arranged in the inner cavity of the filter box, a rotating shaft is arranged on the upper side of the inner cavity of the filter box, a stable bearing is sleeved on the outer wall of the rotating shaft, the outer wall of the stable bearing is fixedly connected with the inner wall of the filter box through a connecting plate, a plurality of uniformly distributed blades are fixedly arranged on the upper side of the outer wall of the rotating shaft, and a brush plate attached to the surface of the filter mesh plate is fixedly connected to the tail end of the rotating shaft.
[0009] By adopting the above technical solution, when the gas enters the inner cavity of the filter box during the negative pressure dust suction process, the gas impacts on the surface of the blade, causing the blade to rotate, which drives the rotation of the rotating shaft, and further enables the brush plate to rotate along the filter mesh plate, scraping off the impurities accumulated on the filter mesh plate, and moving the impurities to both sides along the arc surface of the filter mesh plate, thus preventing the accumulation of impurities on the filter mesh plate from affecting the dust suction effect, and to a certain extent reducing the power consumption of the exhaust fan under the condition of achieving the same negative pressure dust suction effect, thereby realizing the energy-saving effect.
[0010] As a preferred embodiment of the present utility model, a chute is provided on the outer wall of the adjusting plate. A screw motor is fixed at the bottom of the inner cavity of the chute.

A suitable screw slider is sleeved on the outer wall of the screw rod. The outer wall of the screw slider is fixedly connected with the dust collection cover through a connecting plate.
[0011] By adopting the above technical solution, the screw motor can drive the screw rod to rotate, thereby driving the screw slider to lift, and then driving the dust collection cover to lift and adjust the height, so as to adapt to the height of the sieve mesh, get as close to the sieve mesh as possible, and ensure the negative pressure dust suction effect.
[0012] As a preferred embodiment of the present utility model, moving wheels are fixed at the four corners of the bottom of the base.
[0013] By adopting the above technical solution, the setting of the moving wheels makes it convenient to transfer and reposition the whole device.

[0015] By adopting the above technical solution, the setting of the handles makes it convenient to hold the handles and push the device for transfer.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] For an energy-saving dust removal device for screening Astragalus membranaceus seeds in the technical solution of the present application, by arranging the dust collection cover above the sieve mesh and then starting the exhaust fan to generate negative pressure in the filter box, negative pressure is generated in the dust collection cover, so that the raised dust can be sucked away and introduced into the filter box for filtration, thereby realizing the collection of dust and impurities and avoiding pollution to the surrounding air;
[0018] During the negative-pressure dust collection process, when the gas enters the inner cavity of the filter box, the gas impacts on the surface of the blades, causing the blades to rotate. This, in turn, drives the rotation of the rotating shaft, enabling the scraper to rotate along the filter mesh plate. As a result, the impurities accumulated on the filter mesh plate are scraped off and move to both sides along the arc surface of the filter mesh plate, preventing the accumulation of impurities on the filter mesh plate from affecting the dust collection effect. Thus, under the condition of achieving the same negative-pressure dust collection effect, the power consumption of the exhaust fan can be reduced to a certain extent, thereby realizing the energy-saving effect;
[0019] The lead screw motor can drive the rotation of the lead screw, thereby driving the lifting of the lead screw slider, and then driving the lifting and height adjustment of the dust collection hood, enabling the height to adapt to the sieve mesh, getting as close to the sieve mesh as possible to ensure the negative-pressure dust collection effect.

[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution: an energy-saving dust removal device selected for an astragalus seed sieve, including a base 1. A support plate 15 is fixed on one side of the top of the base 1. An adjusting plate 3 is fixed on the outer wall of the support plate 15, and a dust collection hood 4 is connected to the outer wall of the adjusting plate 3;
[0030] Another side wall of the support plate 15 is fixed with a filter box 2. The top of the filter box 2 is communicated with the dust collection hood 4 through a dust suction pipe. In the middle of the top of the base 1, a suction fan 14 is fixed. One end of the suction fan 14 is fixedly communicated with the bottom of the filter box 2 through an air pipe;
[0031] During actual use, the device is transferred near the sieve plate of the vibrating screen, and then the dust collection hood 4 is placed above the mesh plate. When the astragalus seeds are screened by the vibrating screen, the astragalus seeds will vibrate, resulting in dust flying. At this time, the suction fan 14 is used to create negative pressure in the filter box 2, so that the dust can be sucked away by the dust collection hood 4, and the dust and impurities are sucked into the filter box 2 for filtration, avoiding the pollution of the surrounding air caused by dust flying.
[0032] Furthermore, moving wheels 11 are fixed at the four corners of the bottom of the base 1. The arrangement of the moving wheels 11 makes it convenient to transfer and reposition the whole device.
[0033] Even further, a support 12 is fixed at one end of the top of the base 1. On both sides of the outer wall of the support 12, handles 13 are fixed. The arrangement of the handles 13 makes it convenient to hold the handles 13 and push the device for transfer.
[0034] As Figure 1 and 3 shown; an arc-shaped filter mesh plate 21 is fixed in the inner cavity of the filter box 2. A rotating shaft 22 is arranged on the upper side of the inner cavity of the filter box 2. A stable bearing 25 is sleeved on the outer wall of the rotating shaft 22. The outer wall of the stable bearing 25 is fixedly connected with the inner wall of the filter box 2 through a connecting plate. On the upper side of the outer wall of the rotating shaft 22, a plurality of uniformly distributed blades 24 are fixed. The tail end of the rotating shaft 22 is fixedly connected with a brush plate 23 that fits on the surface of the filter mesh plate 21;
[0035] During the negative pressure dust suction process, when the gas enters the inner cavity of the filter box 2, the gas will impact on the surface of the blades 24, so that the blades 24 rotate, which will drive the rotating shaft 22 to rotate, and further make the brush plate 23 rotate along the filter mesh plate 21, so as to scrape off the impurities accumulated on the filter mesh plate 21, and make the impurities move to both sides along the arc surface of the filter mesh plate 21, thus avoiding the accumulation of impurities on the filter mesh plate 21 and affecting the dust suction effect. Therefore, under the condition of achieving the same negative pressure dust suction effect, the power consumption of the suction fan 14 can be reduced to a certain extent, and the energy-saving effect is realized.
[0036] As Figure 1 and 2 shown; a chute is opened on the outer wall of the adjusting plate 3. At the bottom of the inner cavity of the chute, a screw motor 31 is fixed. The outer end of the transmission shaft of the screw motor 31 is fixedly connected with a screw rod 32. The outer end of the screw rod 32 is rotatably connected with the top of the inner cavity of the chute. A matching screw slider 33 is sleeved on the outer wall of the screw rod 32. The outer wall of the screw slider 33 is fixedly connected with the dust collection hood 4 through a connecting plate;
[0037] The lead screw motor 31 can drive the lead screw 32 to rotate, thereby driving the lead screw slider 33 to move up and down, driving the dust collection hood 4 to move up and down to adjust the height, enabling it to adapt to the height of the sieve mesh, getting as close to the sieve mesh as possible to ensure the negative pressure dust suction effect.
[0038] The implementation principle of an energy-saving dust removal device for screening Astragalus membranaceus seeds in this application is as follows: During actual use, the device is moved near the sieve plate of the vibrating sieve. The lead screw motor 31 can drive the lead screw 32 to rotate, thereby driving the lead screw slider 33 to move up and down, driving the dust collection hood 4 to move up and down to adjust the height, enabling it to adapt to the height of the sieve mesh. Then, when the vibrating sieve is used to screen Astragalus membranaceus seeds, the seeds will vibrate, resulting in dust flying. At this time, the suction fan 14 is used to create a negative pressure in the filter box 2, enabling the dust collection hood 4 to suck away the dust, so that the dust and impurities are sucked into the filter box 2 for filtration, preventing dust from polluting the surrounding air. When the gas enters the inner cavity of the filter box 2 during the negative pressure dust suction process, the gas impacts the surface of the blade 24, causing the blade 24 to rotate, driving the rotating shaft 22 to rotate, and then enabling the brush plate 23 to rotate along the filter mesh plate 21, scraping off the impurities accumulated on the filter mesh plate 21 and moving the impurities to both sides along the arc surface of the filter mesh plate 21, thus preventing the impurities from accumulating on the filter mesh plate 21 and affecting the dust suction effect. Therefore, under the condition of achieving the same negative pressure dust suction effect, the power consumption of the suction fan 14 can be reduced to a certain extent, thereby achieving the energy-saving effect.
