[0025] Before pouring the cotton into the rotating annular silo 2, the cotton scraper plate 801 is pushed down by the lifting control rod 7 so that the bottom end of the cotton scraper plate 801 contacts the inner bottom of the rotating annular silo 2, and then the cotton is put in. The cotton grabbing car 3 sucks the cotton and sends it to the next processing step through the cotton conveying pipe 4. During the processing, the cotton scraper plate 801 can scrape the cotton accumulated or adhered to the bottom of the rotating annular silo 2. In addition, a cotton scraping auxiliary slope 803 is set on the side wall of the cotton scraper plate 801. Its purpose is to install the first air outlet component. The first air outlet component is used in conjunction with the cotton scraper plate 801 to avoid accumulation of the scraped cotton. The cotton scraping auxiliary slope 803 also has a guiding effect on the scraped cotton to avoid obstruction of the cotton; in addition, the dry gas sprayed by the first air outlet component can provide a drying effect on the material.

[0026] Here, a first air outlet component is equidistantly arranged on the cotton scraping auxiliary slope 803, and the first air outlet component includes a threaded cavity groove 901, an air jet hole groove 902, a connecting pipe cap 903 and an auxiliary air outlet nozzle 904; the threaded cavity groove 901 is arranged on the cotton scraping auxiliary slope 803, and an air jet hole groove 902 is arranged in the threaded cavity groove 901, the air jet hole groove 902 is connected to the accommodating cavity 804, and the threaded cavity groove 901 is threadedly connected to the connecting pipe cap 903; the pipe mouth diameter of the connecting pipe cap 903 here is equal to the aperture setting of the air jet hole groove 902, and auxiliary air outlet nozzles 904 are equidistantly arranged on the side of the connecting pipe cap 903, and the auxiliary air outlet nozzles 904 are inclined; wherein the auxiliary air outlet nozzle 904 is arranged on the side of the connecting pipe cap 903, and the purpose of its inclined setting is to avoid the cotton wool from affecting the auxiliary air outlet nozzle 904 as much as possible. The first air outlet component can provide a blowing effect for scraping off the accumulated cotton while providing a drying function, thereby reducing the problem of accumulation and adhesion. Furthermore, the connecting pipe cap 903 here is threadedly connected to the threaded cavity groove 901, and the connecting pipe cap 903 is provided with a card-removal setting, and an auxiliary air outlet nozzle 904 is provided on the side of the connecting pipe cap 903. When loosening or screwing in the connecting pipe cap 903, the auxiliary air outlet nozzle 904 is also equivalent to a rotating auxiliary screw block, which makes it easier to loosen and tighten the connecting pipe cap 903, thereby improving the convenience of disassembly and assembly of the connecting pipe cap 903. That is, when the connecting pipe cap 903 needs to be replaced or disassembled for cleaning, the connecting pipe cap 903 is directly rotated until it is separated from the threaded cavity groove 901, and then the new connecting pipe cap 903 is tightened and connected to the threaded cavity groove 901.

[0027] Here, an auxiliary control component is arranged in the accommodating cavity 804, and the auxiliary control component includes a movable strip body 1001, a rectangular ventilation cavity 1002, a drainage connecting groove 1003, a connecting pad 1004, a supporting spring 1005, an auxiliary baffle 1006 and a vent 1007; a supporting spring 1005 is fixedly arranged at the top of the movable strip body 1001, and a connecting pad 1004 is fixedly arranged at the other end of the supporting spring 1005, a rectangular ventilation cavity 1002 is penetrated through the movable strip body 1001, and drainage connecting grooves 1003 are equidistantly arranged on both sides of the movable strip body 1001, the drainage connecting grooves 1003 are inclined, and the drainage connecting grooves 1003 correspond to the setting positions of the jet hole grooves 902, and auxiliary baffles 1006 are equidistantly arranged at the bottom cavity opening of the rectangular ventilation cavity 1002, and vents 1007 are arranged in the auxiliary baffle 1006.

[0028] Here, a second air outlet component is equidistantly arranged in the sealing plate 807, and the second air outlet component includes a movable top column 1101, an auxiliary spring 1102, an auxiliary fixing plate 1103, an air outlet channel 1104 and an auxiliary ball 1105; the movable top column 1101 is movably inserted in the sealing plate 807, and the top of the movable top column 1101 is fixedly provided with an auxiliary fixing plate 1103, the movable top column 1101 is provided with an air outlet channel 1104, and the air outlet channel 1104 extends into the auxiliary fixing plate 1103, the auxiliary fixing plate 1103 is fixedly provided with an auxiliary spring 1102 at the end connected to the movable top column 1101, and the other end of the auxiliary spring 1102 is fixedly provided on the sealing plate 807; the air outlet channel 1104 here corresponds to the setting position of the vent hole 1007; the bottom end surface of the movable top column 1101 is equidistantly and movably embedded with auxiliary balls 1105.

[0029] In this scheme, an auxiliary control component and a second air outlet component are arranged to cooperate with the first air outlet component. That is, when the cotton scraping plate 801 reaches the bottom end of the rotating annular silo 2, the movable top column 1101 is squeezed first in this process, and the other end of the movable top column 1101 squeezes the auxiliary baffle 1006 at the bottom end of the rectangular ventilation cavity 1002, and then squeezes the movable strip body 1001, so that the drainage connecting groove 1003 on the side of the movable strip body 1001 is aligned with the air injection hole groove 902 in the cotton scraping auxiliary slope 803. At this time, the movable top column 1101 is retracted into the accommodating chamber 804, and the dry gas input from the gas hose 802 enters the accommodating chamber 804, and then enters the rectangular ventilation chamber 1002 in the movable strip body 1001, and then enters the jet hole groove 902 from the drainage connecting groove 1003, and finally is ejected from the auxiliary air outlet nozzle 904 on the side of the connecting pipe cap 903; the auxiliary ball 1105 is arranged at the bottom end of the movable top column 1101 to minimize the friction damage to the movable top column 1101 when the movable top column 1101 is under pressure.

[0030] Here, when it is necessary to lift the scraper plate 801, that is, the lifting control rod 7 lifts the scraper plate 801, the pressure on the movable top column 1101 is released, and the movable top column 1101 is reset. At the same time, the movable strip body 1001 is reset under the action of the supporting spring 1005, so that the drainage connecting groove 1003 and the jet hole groove 902 are misaligned, and the movable strip body 1001 is misaligned with the jet hole groove 902. At this time, dry gas can continue to be input into the scraper plate 801 through the gas hose 802. At this time, the gas enters the accommodating chamber 804, and then reaches the rectangular ventilation chamber 1002, and finally passes through the ventilation hole 1007 on the auxiliary baffle 1006 and is ejected from the air outlet channel 1104 in the movable top column 1101, which also has a drying effect on the material in the rotating annular silo 2; when the scraper plate 801 rises, the delivery of dry gas can also be stopped, which has better working flexibility.
