A third mounting shaft is movably installed on the inner wall of the housing, and a material distribution adjustment flap is installed on the side of the third mounting shaft. The plate and the first guide plate are located on both sides of the bottom opening of the feed inlet; a rotating seat is provided at one end of the third mounting shaft extending to the outside of the housing, which is used to drive the third mounting shaft and the material distribution adjustment flap to rotate, and adjust the gap between the material distribution adjustment flap and the first guide plate; a uniformly distributed fixing sleeve is installed at the bottom of the material distribution adjustment flap, and an extension material distribution rod is installed inside the fixing sleeve through a spring. The end of the extension material distribution rod away from the material distribution adjustment flap contacts the side of the first guide plate, which is used to disperse the rice falling between the material distribution adjustment flap and the first guide plate; a transition mechanism is provided at intervals inside the housing, which is used to transition the rice falling from the second guide plate.

[0007] Preferably, a vibration component is installed on the side of the material dispensing adjustment flap to drive the material dispensing adjustment flap and the extended material dispensing rod to vibrate; an indicator component is provided on one side of the rotating seat, and a first adjustment scale is provided on the outer wall of the housing to indicate the rotation status of the material dispensing adjustment flap; a second through hole is opened on the side of the rotating seat, and a first guide component is installed on the outer wall of the housing. The first guide component is located inside the second through hole and is used to limit and guide the rotation of the rotating seat.

[0008] Preferably, the transition mechanism includes a mounting bracket movably mounted inside the housing via a second mounting shaft, with a transition plate mounted on the side of the mounting bracket near the air inlet; an extension rod is mounted on one side of the mounting bracket, and a first through hole is provided on the side wall of the housing, with the end of the extension rod away from the transition plate extending to the outside of the housing through the first through hole.

[0009] Preferably, the air supply adjustment mechanism includes a first mounting shaft movably installed inside the housing, a mounting seat mounted on the first mounting shaft, and an air supply adjustment plate mounted on the side of the mounting seat near the air supply inlet opening; an air supply adjustment plate adjustment mechanism is provided at the end of the first mounting shaft extending outside the housing for adjusting the tilt angle of the air supply adjustment plate.

[0010] Preferably, the air supply adjustment plate adjustment mechanism includes a toggle handle movably disposed on the outer wall of the housing, a mounting wing is provided on one side of the toggle handle, a movable component is movably mounted on the side of the mounting wing, and the side of the movable component is connected to one end of the first mounting shaft through a connecting component; the end of the mounting wing away from the toggle handle is connected to one end of the first mounting shaft located at the top of the housing.

[0011] Preferably, the toggle handle has a third through hole on its side, and the outer wall of the housing is provided with a second guide component, which is located inside the third through hole and is used to guide and limit the rotation of the toggle handle.

[0012] Preferably, the side of the toggle handle is provided with a second adjustment scale to indicate the rotation angle of the toggle handle and the air supply adjustment plate.

[0015] The beneficial effects of this invention are as follows:

[0016] In use, the rice to be cleaned is fed from the inlet onto the first guide plate. Rotating the rotating seat drives the third mounting shaft and the distributing adjustment flap to rotate, thereby adjusting the gap between the distributing adjustment flap and the first guide plate, and consequently adjusting the rice feed rate and quantity. During the rotation of the distributing adjustment flap, a spring pushes the extended distributing rod, ensuring one end of the extended distributing rod always rests against the side of the first guide plate. The extended distributing rod disperses the rice falling between the distributing adjustment flap and the first guide plate, ensuring the rice is evenly distributed onto the second guide plate. The rice on the second guide plate slides onto the transition mechanism. As the rice falls between the two adjacent transition mechanisms, the airflow inside the suction hood draws air from the air inlet into the suction hood, drawing the chaff from the falling rice into the suction hood, achieving the cleanliness of the rice. Furthermore, the airflow entering the housing through the air inlet can be adjusted according to usage requirements via the air inlet adjustment mechanism, facilitating easy adjustment.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1 to 6A rice processing impurity removal device includes a housing 1, with a feed inlet 7 at the top and a discharge outlet 3 at the bottom. The inner wall of the housing 1 is inclined. A suction hood 10 is provided on one side of the housing 1, and a suction port 11 is provided at the end of the suction hood 10 away from the housing 1. A make-up air inlet 4 is provided on the side of the housing 1 away from the suction hood 10, and a make-up air adjustment mechanism 5 is movably installed inside the make-up air inlet 4 to adjust the air volume entering the housing 1 through the make-up air inlet 4. A first guide plate 6 and a second guide plate 9 are alternately installed on the top of the inner wall of the housing 1 to guide the rice fed into the feed inlet 7. A third mounting shaft 14 is movably installed on the inner wall of the housing 1, and a material distribution adjustment flap 8 is installed on the side of the third mounting shaft 14. Plate 8 and the first guide plate 6 are located on both sides of the bottom opening of the feed inlet 7, respectively; a rotating seat 13 is provided at one end of the third mounting shaft 14 extending to the outside of the housing 1, which is used to drive the third mounting shaft 14 and the material distribution adjustment flap 8 to rotate, and adjust the gap size between the material distribution adjustment flap 8 and the first guide plate 6; a uniformly distributed fixing sleeve 30 is installed at the bottom of the material distribution adjustment flap 8, and an extension material distribution rod 31 is installed inside the fixing sleeve 30 through a mounting spring 32. The end of the extension material distribution rod 31 away from the material distribution adjustment flap 8 contacts the side of the first guide plate 6, which is used to disperse the rice falling between the material distribution adjustment flap 8 and the first guide plate 6; a transition mechanism 12 is provided at intervals inside the housing 1, which is used to transition the rice falling from the second guide plate 9.

[0026] In use, the rice to be cleaned is fed from the inlet 7 onto the first guide plate 6. Rotating the rotating base 13 drives the third mounting shaft 14 and the distributing adjustment flap 8 to rotate, thereby adjusting the gap between the distributing adjustment flap 8 and the first guide plate 6, and thus adjusting the rice feeding amount and feeding rate. During the rotation of the distributing adjustment flap 8 by the rotating base 13, the mounting spring 32 pushes the extended distributing rod 31, ensuring that one end of the extended distributing rod 31 always abuts against the side of the first guide plate 6. The extended distributing rod 31 maintains contact with the side of the distributing adjustment flap 8 and the first guide plate 6. The falling rice is dispersed to ensure it falls evenly onto the second guide plate 9. The rice slides down the second guide plate 9 onto the transition mechanism 12. As the rice falls between two adjacent transition mechanisms 12, the airflow inside the suction hood 10 is drawn in. Air from inside the housing 1 flows from the opening of the air supply port 4 into the interior of the suction hood 10, which can draw the chaff from the falling rice into the suction hood 10, thus achieving the effect of removing impurities from the rice. The amount of air entering the housing 1 through the air supply port 4 can be adjusted according to the usage requirements via the air supply adjustment mechanism 5, making it easy to adjust.

[0027] In a preferred embodiment of the present invention, a vibration component 29 is installed on the side of the distributing adjustment flap 8 to drive the distributing adjustment flap 8 and the extended distributing rod 31 to vibrate, thereby promoting the feeding of rice and improving the dispersing effect of the extended distributing rod 31 on rice. An indicator component 17 is provided on one side of the rotating seat 13, and a first adjustment scale 18 is provided on the outer wall of the housing 1 to indicate the rotation status of the distributing adjustment flap 8. A second through hole 15 is opened on the side of the rotating seat 13, and a first guide component 16 is installed on the outer wall of the housing 1. The first guide component 16 is located inside the second through hole 15 and is used to limit and guide the rotation of the rotating seat 13. When the rotating seat 13 is rotated, the tilt status of the distributing adjustment flap 8 can be determined according to the position of the indicator component 17 pointing to the first adjustment scale 18, that is, the amount of rice fed.

[0028] In a preferred embodiment of the present invention, the transition mechanism 12 includes a mounting frame 122 movably mounted inside the housing 1 via a second mounting shaft 121. A transition plate 124 is mounted on the side of the mounting frame 122 near the air inlet 4. An extension rod 123 is mounted on one side of the mounting frame 122. A first through hole 125 is provided on the side wall of the housing 1. One end of the extension rod 123 away from the transition plate 124 extends to the outside of the housing 1 through the first through hole 125. During the impurity removal process, rice falls onto two adjacent transition plates 124 in sequence. The extension rod 123 can be moved within the first through hole 125, thereby adjusting the tilt angle of the transition plate 124 for easy adjustment.

[0029] In a preferred embodiment of the present invention, the air supply adjustment mechanism 5 includes a first mounting shaft 51 movably installed inside the housing 1, a mounting seat 52 mounted on the first mounting shaft 51, and an air supply adjustment plate 53 mounted on the side of the mounting seat 52 near the opening of the air supply port 4; an air supply adjustment plate adjustment mechanism 33 is provided at one end of the first mounting shaft 51 extending to the outside of the housing 1, for adjusting the tilt angle of the air supply adjustment plate 53.

[0030] In a preferred embodiment of the present invention, the air supply regulating plate adjusting mechanism 33 includes a toggle handle 25 movably disposed on the outer wall of the housing 1. A mounting wing 26 is provided on one side of the toggle handle 25. A movable component 23 is movably mounted on the side of the mounting wing 26. The side of the movable component 23 is connected to one end of the first mounting shaft 51 through a connecting component 22. The end of the mounting wing 26 away from the toggle handle 25 is connected to one end of the first mounting shaft 51 located at the top of the housing 1.

[0031] In a preferred embodiment of the present invention, a third through hole 24 is provided on the side of the toggle handle 25, and a second guide member 28 is provided on the outer wall of the housing 1. The second guide member 28 is located inside the third through hole 24 and is used to guide and limit the rotation of the toggle handle 25.

[0032] In a preferred embodiment of the present invention, a second adjustment scale 27 is provided on the side of the toggle handle 25 to indicate the rotation angle of the toggle handle 25 and the air supply adjustment plate 53. The toggle handle 25 can be toggled to rotate around one end of the mounting wing 26, thereby causing the movable part 23 to move accordingly. The movement of the movable part 23 causes the first mounting shaft 51 to rotate, thereby achieving uniform adjustment of the tilt angle of the air supply adjustment plate 53. During the rotation of the toggle handle 25, the second guide part 28 moves within the third through hole 24 to guide and limit the rotation of the toggle handle 25. The tilt angle of the air supply adjustment plate 53 can be determined based on the relative position of the second guide part 28 and the second adjustment scale 27, that is, the amount of air intake at the air supply port 4 can be determined, which facilitates adjustment.

[0033] In a preferred embodiment of the present invention, observation windows 2 are provided on the side walls of the housing 1 and the feed inlet 7 for observing the interior of the housing 1 and the feed inlet 7.
