[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-13 As shown, an embodiment of the present invention provides a millet hulling debris removal device, comprising: refer to Figure 1 , Figure 2 , Figure 3 The outer casing 1 has an upper feeding chamber 101 with a feeding port above it and a shelling chamber 102 below it. The bottom of the shelling chamber 102 has a discharge port with a material distribution plate 107 fixedly connected to the discharge port. Below the material distribution plate 107 is a discharge plate 106 with the material distribution plate 107 and the discharge plate 106 tilting in opposite directions. The front side of the shelling chamber 102 has a dust suction chamber 103 with a discharge port below it and a discharge ramp 104 fixedly installed at the discharge port. The discharge plate 106 has a ventilation area 1061 and a blocking block 1062 fixedly connected to the bottom of the discharge plate 106. The connection between the blocking block 1062 and the discharge plate 106 has an arc portion 1063. The bottom of the outer casing 1 has a support leg 105 fixedly connected to it. The material distribution plate 107 guides and conveys the dehulled material to the top of the discharge plate 106, allowing the material to fall above the ventilation zone 1061. Under the influence of gravity, the material will roll down along the discharge plate 106. The ventilation zone 1061 is an area with evenly distributed ventilation holes to ensure that airflow can penetrate the ventilation zone 1061 and the material will not fall through the ventilation holes. The blocking block 1062 can block a certain amount of material to prevent the material from falling directly. It works in conjunction with the subsequent wave component to intermittently lift the material. In order to prevent the millet material from not being lifted, the height of the blocking block 1062 can be selected as 1 cm.

[0020] refer to Figure 1 , Figure 9 The dust collection assembly 2 is located on the outside of the outer shell 1 and is used for dust collection. The dust collection assembly 2 includes a square dust collection shell 201 fixedly installed on the outside of the outer shell 1. A dust collection fan 202 is fixedly connected to the end of the square dust collection shell 201, and a water box 205 is fixedly connected to the bottom of the square dust collection shell 201. A filter element 207 for filtration is provided inside the square dust collection shell 201. The lower part of the filter element 207 passes through the lower wall of the square dust collection shell 201 and is located inside the water box 205. An air supply element 206 for conveying dust-laden airflow is provided on the air inlet side of the filter element 207. An upper dust collection pipe 203 and a lower dust collection pipe 204 are fixedly connected to the end of the square dust collection shell 201 away from the dust collection fan 202. The dust collection chamber 103 and the lower dust collection pipe 204 are interconnected. During vacuuming operations, the vacuum blower 202 operates under the control of an external power supply and controller. It can blow the airflow outward from the square vacuum casing 201 to provide the necessary suction for vacuuming. The vacuum blower 202 can be a centrifugal fan.

[0021] refer to Figure 9 , Figure 11The filter element 207 includes an active roller 2072, a driven roller 2074, and a drive motor 2071. A filter belt 2073 is provided between the active roller 2072 and the driven roller 2074. The outer surface of the filter belt 2073 is uniformly provided with receiving grooves 9. The output end of the drive motor 2071 is fixedly connected to the active roller 2072. The driven roller 2074 is rotatably installed in the water box 205, the active roller 2072 is rotatably installed in the square dust collection shell 201, and the drive motor 2071 is fixedly installed on the outside of the square dust collection shell 201. During filtration, the drive motor 2071 operates under the control of the external power supply and controller, driving the active roller 2072 to rotate. The rotation of the active roller 2072 and the driven roller 2074 drives the filter belt 2073 to move. To ensure that impurities filtered from the surface of the filter belt 2073 are cleaned, the filter belt 2073 rotates from top to bottom on its windward side. Figure 11 The filter belt 2073 can rotate clockwise. Impurities filtered out by the filter belt 2073 will enter the water box 205. The water in the water box 205 can wash away the impurities from the filter belt 2073, ensuring that the filter belt 2073 always has a filtering function and that the filtering is continuous, without the need for frequent replacement of the filter belt 2073. The receiving groove 9 on the outer surface of the filter belt 2073 is used to hold impurities, increasing the amount of impurities that the filter belt 2073 can carry. The filter belt 2073 only needs to filter out larger particles of flying debris. Therefore, the filter belt 2073 can be made of cotton or linen, which ensures both air permeability and meets the needs of filtering flying debris.

[0022] refer to Figure 9 , Figure 10 The air supply component 206 includes a gradient shell 2064 fixedly installed inside the square dust collection shell 201. A movable frame 2062 is slidably connected inside the gradient shell 2064. An air receiving plate 2063 is fixedly connected to the air inlet end of the movable frame 2062. An air supply frame 2061 is fixedly connected to the end of the movable frame 2062 away from the gradient shell 2064. During air supply operation, the dust-laden airflow entering the square suction housing 201 from the upper suction pipe 203 and lower suction pipe 204 will impact the receiving plate 2063. The thrust generated by the airflow overcomes the friction between the moving frame 2062 and the gradient shell 2064, causing the air supply frame 2061 to approach and adhere to the surface of the filter belt 2073. Since the filter belt 2073 is in motion, the surface of the air supply frame 2061 in contact with the filter belt 2073 should be designed as a smooth surface to ensure that the movement of the filter belt 2073 does not affect the state of the air supply frame 2061. The dust-laden airflow, obstructed by the receiving plate 2063, will bypass the receiving plate 2063, pass through the moving frame 2062, and pass through the filter belt 2073, preventing the dust-laden airflow from being too dispersed and causing the dust-laden airflow to leak from below the filter belt 2073, thus ensuring the stability of the filtration state. refer to Figure 3, Figure 5 , Figure 6 The material distribution component 3 is located in the feeding chamber 101 and is used to uniformly release materials. The material distribution component 3 includes feeding plates 301 symmetrically arranged on the inner wall of the feeding chamber 101. An aggregating plate 302 is fixedly connected to the lower part of the feeding plates 301. A retaining ring 303 is fixedly connected between the two feeding plates 301. A distribution roller 304 is provided on the inner side of the retaining ring 303. The distribution roller 304 is rotatably mounted on the outer shell 1. A material receiving cavity 305 is provided on the circumferential surface of the distribution roller 304. During the material distribution process, the millet material enters the material receiving cavity 305 along the feed plate 301. As the distribution roller 304 rotates, only the millet material in one material receiving cavity 305 will fall between the two gathering plates 302, ensuring that the material release is uniform and stable, and ensuring good quality of millet hulling. The retaining ring 303 restricts the material from entering the two ends of the distribution roller 304, and also reserves space at both ends for subsequent hulling operations, preventing the material at both ends from not being fully squeezed and kneaded for hulling.

[0023] refer to Figure 3 , Figure 13 The dust-collecting component 4 is located above the feed inlet and is used to absorb dust. The dust-collecting component 4 includes an upper frame 401 fixedly installed on the top of the outer shell 1. An upper dust-collecting shell 403 is fixedly connected to the upper part of the upper frame 401. An upper dust-collecting port 402 is provided at the lower part of the upper dust-collecting shell 403. The upper dust-collecting shell 403 is connected to the upper dust-collecting pipe 203. Dust generated during material dumping is sucked in by the upper suction port 402 and then enters the square suction housing 201 through the upper suction pipe 203, preventing dust from spreading and polluting the processing environment and ensuring the health of the staff.

[0024] refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 The blowing assembly 5 is located below the material drop plate 106 and is used to generate a controllable airflow that blows toward the material drop plate 106. The blowing assembly 5 includes a blowing shell 502 fixedly installed at the rear of the outer shell 1. An axial flow fan 501 is fixedly installed on the rear side of the blowing shell 502, and a blowing port 503 is provided on the front side of the blowing shell 502. During the blowing operation, the axial flow fan 501 operates under the control of the external power supply and controller, and the generated airflow enters the blower housing 502 and is then blown out from the blower outlet 503, which can provide a certain amount of airflow to the material drop plate 106. The size of the airflow can be controlled by controlling the rotation speed of the axial flow fan 501. The higher the rotation speed, the larger the airflow blown out.

[0025] refer to Figure 3 , Figure 4The oscillating component is located between the blowing assembly 5 and the dropping plate 106 and is used to drive the dropping plate 106 to oscillate. The oscillating component includes an electromagnet 801 fixedly installed on the inner wall of the outer shell 1. A permanent magnet 802 is provided above the adsorption end of the electromagnet 801. The permanent magnet 802 is fixedly connected to the dropping plate 106. A connecting spring 803 is fixedly connected between the blowing shell 502 and the dropping plate 106. When the electromagnet 801 is energized, it can attract each other to the permanent magnet 802. During fluctuating operation, electromagnet 801 operates intermittently under the action of external power supply and controller. When electromagnet 801 is energized, the magnetic force it generates can attract permanent magnet 802, overcome the elastic force of connecting spring 803, and drive the lower end of drop plate 106 close to electromagnet 801. When electromagnet 801 is de-energized, the magnetic force disappears, and under the action of the elastic force of connecting spring 803 in a compressed state, it will drive drop plate 106 away from electromagnet 801, lifting drop plate 106 and the material and debris on it, so that the grains and debris are fully separated. Then, under the action of airflow, the debris is blown up, ensuring that the debris can be fully separated from the grains and improving the debris removal rate.

[0026] refer to Figure 1 , Figure 3 , Figure 8 The shelling assembly 7 is located inside the shelling cavity 102 and is used for shelling. The shelling assembly 7 includes a second rubber roller 704, a first rubber roller 702, an electric push rod 705, and a second shelling motor 703. The output end of the electric push rod 705 is fixedly connected to a movable seat 706. The first shelling motor 701 is fixedly installed on the movable seat 706. The first shelling motor 701 is fixedly connected to the first rubber roller 702. The first rubber roller 702 is rotatably installed on the movable seat 706. The second rubber roller 704 is rotatably installed inside the shelling cavity 102. The second shelling motor 703 is fixedly connected to the second rubber roller 704. The inner wall of the shelling cavity 102 is provided with a moving groove, and the rotation shaft of the first rubber roller 702 passes through the moving groove. During the shelling operation, the electric push rod 705 operates under the control of the external power supply and controller, driving the moving seat 706 to move, thereby controlling the gap between the first rubber roller 702 and the second rubber roller 704. The appropriate gap is selected according to the type of material to be shelled. For example, if the material particles are small, the gap is adjusted to be smaller, and vice versa. The shelling motors 701 and 703 operate under the control of the external power supply and controller, respectively driving the first rubber roller 702 and the second rubber roller 704 to rotate. The first rubber roller 702 and the second rubber roller 704 rotate in opposite directions, and the difference in their speeds generates a squeezing and kneading force, thereby achieving the purpose of shelling.

[0027] refer to Figure 8The transmission assembly 6 is located on the rear side of the outer shell 1 and is used to transmit the power of the shelling assembly 7 to the material distribution assembly 3. The transmission assembly 6 includes a driving pulley 601 and a driven pulley 603, and a connecting belt 602 is provided between the driving pulley 601 and the driven pulley 603. The driving pulley 601 is fixedly connected to the rotation shaft of the second rubber roller 704, and the driven pulley 603 is fixedly connected to the rotation shaft of the distribution roller 304. When the second rubber roller 704 rotates, it will drive the drive pulley 601 to rotate, which in turn drives the driven pulley 603 to rotate via the connecting belt 602, thereby driving the equalizing roller 304 to rotate, thus transmitting power.

[0028] Working principle: The millet material is poured in from the feed port and enters the material receiving cavity 305 along the feed plate 301. As the equalizing roller 304 rotates, only the millet material in one material receiving cavity 305 will fall between the two gathering plates 302, ensuring that the material release is uniform and stable. When the vacuum blower 202 is working, it can blow the airflow out of the square vacuum casing 201 to the outside, providing the necessary suction for vacuuming; the dust generated when pouring materials will be sucked in by the upper vacuum port 402 and then enter the square vacuum casing 201 through the upper vacuum pipe 203, so as to avoid dust from spreading and polluting the processing environment and to ensure the health of the staff. When the shelling motor 1 701 and the shelling motor 2 703 work, they drive the rubber roller 1 702 and the rubber roller 2 704 to rotate respectively. The rubber roller 1 702 and the rubber roller 2 704 rotate in opposite directions and have different speeds, which can generate squeezing and kneading force, thereby achieving the purpose of shelling. When the second rubber roller 704 rotates, it will drive the drive pulley 601 to rotate, which in turn drives the driven pulley 603 to rotate through the connecting belt 602, thereby driving the equalizing roller 304 to rotate, thus transmitting power. As the material passes through the distribution plate 107 and falls along the discharge plate 106, the axial flow fan 501 works, and the generated airflow enters the blower housing 502 and is then blown out from the blower outlet 503, which can provide a certain amount of airflow to the discharge plate 106. Electromagnet 801 operates intermittently. When electromagnet 801 is energized, the magnetic force it generates can attract permanent magnet 802, overcoming the elastic force of connecting spring 803, and driving the lower end of the material drop plate 106 closer to electromagnet 801. When electromagnet 801 is de-energized, the magnetic force disappears, and under the action of the elastic force of connecting spring 803 in a compressed state, the material drop plate 106 will be driven away from electromagnet 801, lifting the material drop plate 106 and the material and debris on it, so that the grains and debris are fully separated. Then, under the action of airflow, the debris is blown up, ensuring that the debris can be fully separated from the grains, thus improving the debris removal rate. The dust-laden airflow entering the square vacuum shell 201 from the upper suction pipe 203 and the lower suction pipe 204 will impact the air receiving plate 2063. The thrust generated by the airflow overcomes the friction between the moving frame 2062 and the gradient shell 2064, and drives the air supply frame 2061 to approach and attach to the surface of the filter belt 2073. During filtration, the drive motor 2071 operates, driving the active roller 2072 to rotate. The rotation of the active roller 2072 and the driven roller 2074 can drive the filter belt 2073 to move. The impurities filtered out by the filter belt 2073 will enter the water box 205. The water in the water box 205 can clean the impurities from the filter belt 2073, ensuring that the filter belt 2073 always has a filtration function and ensuring continuous filtration without the need for frequent replacement of the filter belt 2073. The entire shelling process does not generate any flying dust, ensuring that the working environment is not polluted and protecting the health of the staff.
