Description

Technical Field

[0001] The present application relates to the technical field of rice processing, and in particular to a screening device used in rice processing. Background Art

[0002] Rice processing is mainly divided into three stages: cleaning, husking and milling. The cleaning stage is mainly to remove impurities such as mud, stones and husks, and then husking. After husking, the husks need to be removed. After removing the husks, the rice becomes brown rice. The brown rice is milled to remove the bran layer, and what is left is the rice that can be sold directly.

[0003] After husking, brown rice and husk are mixed together. Since the husk is lighter than brown rice, it can be removed by air separation, that is, the mixture of brown rice and husk is blown out of the brown rice by blowing air, thereby achieving the purpose of removing the husk. In the actual operation process, if the brown rice and husk are adhered together after husking, these adhered husks cannot be removed by air separation, resulting in the presence of husks in the rough rice after air separation, affecting subsequent processing.

[0004] In view of the above problems, the present application proposes a screening device for use in rice processing. Summary of the invention

[0005] The embodiment of the present application provides a screening device for use in rice processing to solve the problem in the related art that conventional air separation cannot separate brown rice husks that are adhered together.

[0006] In a first aspect, a screening device for use in rice processing is provided, comprising:

[0007] Mounting frame;

[0008] A drum, the drum rotates on the mounting frame and has two openings at both ends of the drum in the axial direction, and a tumbling space for placing rough rice and husks is provided in the drum;

[0009] Two blowing structures, each of which includes a fan, are respectively arranged near the opening and blow air into the drum.

[0010] In some embodiments, two baffles and a plurality of transverse plates are also included;

[0011] The two baffles are respectively located at the two openings and are connected to the drum, and a plurality of transverse plates are located between the two baffles and are connected to the inner wall of the drum.

[0012] In some embodiments, two rotating gears are further included;

[0013] The mounting frame includes a base plate, two rotating rings and an inner cavity;

[0014] The two rotating rings are arranged on the bottom plate and a rotating space for installing the roller is provided in the rotating ring. The inner cavity is located in the bottom plate and the rotating space is communicated with the inner cavity. The two rotating gears are connected to the outer wall of the roller, and the two rotating gears are respectively located in the two rotating spaces.

[0015] In some embodiments, the mounting frame further comprises a duplex gear;

[0016] The double gear is rotatably connected in the inner cavity, and the double gear is respectively meshed with the two rotating gears, and the double gear is meshed with the two rotating gears at the connection point between the rotating space and the inner cavity.

[0017] In some embodiments, the mounting frame further includes a first gear, a second gear, and a motor;

[0018] The first gear and the second gear are both bevel gears, the first gear is connected to the double gear, the second gear is meshed with the first gear, and the motor output end is connected to the second gear.

[0019] In some embodiments, the blowing structure includes a blowing housing and a leakage hole;

[0020] The fan is arranged in the blowing shell, the blowing shell is connected to the mounting frame and the blowing shell is rotatably connected to the drum, and the leakage hole is opened on the blowing shell.

[0021] The embodiment of the present application provides a screening device for rice processing. Since the present application puts brown rice and husks into a drum, and the drum rotates on a mounting frame, the husks and brown rice inside the drum gradually climb upward along with the rotation of the inner wall of the drum. When the husks and brown rice rise to a certain height, the husks and brown rice separate from the inner wall of the drum and fall downward. During the falling process, the fan blows out the husks that are not adhered. After falling, the adhered husks will be separated from the brown rice and blown out by the fan when it falls next time. Therefore, the present application can effectively avoid the problem of residual husks after air selection due to the adhesion of husks to brown rice. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a screening device for use in rice processing, which can solve the problem in the related art that brown rice husks that are stuck together cannot be separated.

[0031] See also Figures 1 to 5 A screening device for rice processing, comprising: a mounting frame 1, a drum 2 and two blowing structures 4, wherein the drum 2 rotates on the mounting frame 1 and two openings 3 are respectively provided at both ends of the drum 2 in the axial direction, and a rolling space for placing rough rice and husks is provided in the drum 2, and the blowing structure 4 comprises a fan 41, wherein the two fans 41 are respectively arranged near the openings 3 and the fans 41 blow air into the drum 2;

[0032] During the implementation, the husks and brown rice are placed in the drum 2, and the drum 2 rotates at a fixed position on the mounting frame 1. During the rotation of the drum 2, the husks and brown rice rise along with the inner wall of the drum 2 due to the centrifugal force. After the husks and brown rice rise to a certain height, the husks and brown rice fall from the inner wall of the drum 2. When the husks and brown rice fall, the husks adhered to the brown rice are dropped and beaten, and the brown rice and the husks are separated.

[0033] At the same time, when the husks and brown rice are falling, the fan 41 on one side is turned on to blow air into the drum 2. Since the quality difference between the brown rice and the husks is large, the husks can be blown out of the drum 2 relatively easily.

[0034] Furthermore, in this embodiment, two baffles 5 and a plurality of transverse plates 6 are also included;

[0035] The two baffles 5 are respectively located at the two openings 3 and the baffles 5 are connected to the drum 2, and the plurality of transverse plates 6 are located between the two baffles 5 and the transverse plates 6 are connected to the inner wall of the drum 2;

[0036] The two baffles 5 can prevent the brown rice on the drum 2 from rolling out of the drum 2 due to the air blown by the fan 41, and the plurality of transverse plates 6 can ensure that the brown rice and the husk are brought to a high point by the drum 2, thereby ensuring that the brown rice is separated from the husk.

[0037] Furthermore, in this embodiment, two rotating gears 7 are also included;

[0038] The mounting frame 1 comprises a base plate 11, two rotating rings 12 and an inner cavity 13;

[0039] The two rotating rings 12 are arranged on the bottom plate 11 and a rotating space for installing the drum 2 is arranged in the rotating ring 12, the inner cavity 13 is located in the bottom plate 11 and the rotating space is communicated with the inner cavity 13, the two rotating gears 7 are connected to the outer wall of the drum 2, and the two rotating gears 7 are respectively located in two rotating spaces;

[0040] The rotating gear 7 is inside the rotating ring 12 and is rotationally connected to the rotating ring 12 . The two rotating gears 7 rotate in the rotating space, so that the drum 2 rotates at a fixed position on the mounting frame 1 .

[0041] Specifically, in this embodiment, the mounting frame 1 further includes a double gear 14;

[0042] The double gear 14 is rotatably connected in the inner cavity 13, and the double gear 14 is respectively meshed with the two rotating gears 7, and the double gear 14 is meshed with the two rotating gears 7 at the connection point between the rotating space and the inner cavity 13;

[0043] The double gear 14 is meshed with the two rotating gears 7 , and the double gear 14 is driven to rotate to drive the drum 2 to rotate.

[0044] More specifically, in this embodiment, the mounting frame 1 further includes a first gear 15, a second gear 16 and a motor 17;

[0045] The first gear 15 and the second gear 16 are both bevel gears. The first gear 15 is connected to the double gear 14, the second gear 16 is meshed with the first gear 15, and the output end of the motor 17 is connected to the second gear 16;

[0046] By meshing the first gear 15 with the second gear 16 , the motor 17 drives the second gear 16 to rotate, thereby driving the first gear 15 and the double gear 14 to rotate, and further driving the drum 2 to rotate.

[0047] Preferably, in this embodiment, the blowing structure 4 includes a blowing housing 42 and a leakage hole 43;

[0048] The fan 41 is disposed in the blowing housing 42, the blowing housing 42 is connected to the mounting frame 1 and the blowing housing 42 is rotatably connected to the drum 2, and the leakage hole 43 is opened on the blowing housing 42;

[0049] The husks are blown onto the blowing housing 42 by the fan 41 , and finally the husks slide downwards and leak out from the leakage hole 43 .

[0050] Here’s how this application works:

[0051] During the implementation process, the drum 2 rotates at a fixed position on the mounting frame 1 through the rotating gear 7 and the rotating ring 12, and the husks and brown rice are placed in the drum 2. During the rotation of the drum 2, the husks and brown rice will rise along with the inner wall of the drum 2. After the husks and brown rice rise to a certain height, the husks and brown rice fall from the inner wall of the drum 2. When the husks and brown rice fall, the husks adhered to the brown rice fall and fall, and the brown rice and the husks are separated. The plurality of horizontal plates 6 can ensure that the brown rice and the husk drum 2 are brought to a higher point, so as to ensure that the brown rice and the husks are separated.

[0052] At the same time, when the husks and brown rice fall, the fan 41 blows air into the drum 2. Since the quality difference between the brown rice and the husks is large, the husks can be easily blown out of the drum 2 and hit on the blowing shell 42. Finally, the husks slide downward and leak out from the leakage hole 43. The two baffles 5 can prevent the brown rice on the drum 2 from rolling out of the drum 2 due to the air blowing by the fan 41.
