The materials with impurities can be screened by subsequent air separation equipment for impurities and grain materials, so as to realize the threshing and separation of the residual ears on the grain materials, which is beneficial to subsequent processing.

[0030] In this embodiment, the housing assembly 1 includes a frame 11, a plurality of support seats 13, a plurality of housing structures 12, a baffle plate 14, a discharge hopper 15, and a suction air pipe 16; the frame 11 is fixedly connected to the feed pipe 5 and is located on the side of the feed pipe 5; the plurality of support seats 13 are respectively fixedly connected to the frame 11 and are respectively located on the side of the frame 11; the plurality of housing structures 12 are respectively located on the side of the frame 11, and the housing structure 12 includes a protective cover 121, two rotating parts 122, and an aggregate hopper 123; the protective cover 121 is located on the side of the frame 11; the two rotating parts 122 are located on both sides of the protective cover 121, and the rotating part 122 includes a connecting plate 124, a rotating plate 125, and a plug pin 126; the connecting plate 124 is fixedly connected to the protective cover 121 and is located on the side of the protective cover 121; the rotating plate 125 is fixedly connected to the side of the connecting plate 124; the plug pin 126 penetrates through the rotating plate 125; the aggregate hopper 123 is respectively fixedly connected to the two connecting plates 124 and is located between the two connecting plates 124; the baffle plate 14 is fixedly connected to the frame 11 and is located outside the rotor 3; the discharge hopper 15 is fixedly connected to the frame 11 and is located on the side of the frame 11 and is below the aggregate hopper 123; the suction air pipe 16 is fixedly connected to the frame 11 and is located above the frame 11, and the feed pipe 5 penetrates through the suction air pipe 16. The frame 11 can be tripod or four-legged according to the situation. The frame 11 is used to provide support for the entire grain processor. Connect the end of the suction air pipe 16 far from the stator 6 to an external air extractor. Turn on the air extractor, control the drive assembly 2 to drive the rotor 3 to rotate. The rotor 3 drives the plurality of rotor blades 4 to rotate. Put the rice, wheat, or other grain materials to be processed into the feed pipe 5. The materials enter the gap between the stator 6 and the rotor 3 through the feed pipe 5. The rotor blades 4 and the stator blades 7 are arranged crosswise and at a certain angle. The rotation of the rotor blades 4 generates agitation and impact on the materials, so as to thresh the residual ears in the materials, break or tear sundries such as soil clods and straws. Under the action of the centrifugal force of the rotation of the rotor 3 and the shearing force of the rotor blades 4, the materials are evenly thrown to the surroundings. When the materials contact the baffle plate 14, their movement direction changes and they are scattered obliquely upward in a loose state, which is conducive to the air flow to take away the sundries therein. The residual ears, soil clods, straws and other sundries are sucked away upward by the suction air pipe 16. The clean materials fall into the aggregate hopper 123 under the action of gravity and flow out of the discharge hopper 15, thus completing the processing of the materials, which is greatly beneficial to the subsequent processing. Wear-resistant cast iron plates are provided on the inner walls of the baffle plate 14 and the protective cover 121 to improve the durability.Inserting the bolt 126 into the rotating plate 125 and the support base 13 can connect the rotating plate 125 and the support base 13 together. When it is necessary to perform maintenance on the inside of the grain processor, remove the bolt 126 on one side of the shield 121 from the rotating plate 125 and the support base 13, and then rotate the shield 121 with the bolt 126 on the other side of the shield 121 as the axis. The shield 121 drives the aggregate hopper 123 to rotate through the connecting plate 124, so that the housing structure 12 can be opened, and it is convenient for the staff to perform maintenance on the components inside the grain processor.

[0031] In this embodiment, the housing assembly 1 further includes an inner fairing 17; the inner fairing 17 is fixedly connected to the stator 6 and is located above the stator 6. Debris such as residual ears of grain, soil clods, and straw sticks is sucked away by the suction pipe 16 upward through the gap between the shield 121 and the inner fairing 17.

[0032] In this embodiment, the feed pipe 5 includes an upper pipe body 51, a middle pipe body 52, and a lower pipe body 53; the upper pipe body 51 is fixedly connected to the suction pipe 16 and penetrates through the suction pipe 16; the middle pipe body 52 is detachably connected to the upper pipe body 51 and is located at the bottom of the upper pipe body 51; the lower pipe body 53 is detachably connected to the middle pipe body 52 and is detachably connected to the stator 6 and is located between the middle pipe body 52 and the stator 6. The middle pipe body 52 and the upper pipe body 51 are connected by bolts, so that the upper pipe body 51 and the middle pipe body 52 can be disassembled. The lower pipe body 53 and the middle pipe body 52 are connected by bolts, so that the lower pipe body 53 and the middle pipe body 52 can be disassembled. The stator 6 and the lower pipe body 53 are connected by bolts, so that the stator 6 and the lower pipe body 53 can be disassembled. After opening the housing structure 12, the stator 6 can be disassembled to replace the stator blades 7. The feed pipe 5 is provided in a three-section type to facilitate the disassembly and assembly of the feed pipe 5 and the stator 6.

[0033] In this embodiment, the driving assembly 2 includes a motor 21, a driving sheave 22, a driven sheave 23, a V-belt 24, a main shaft 25 and a bearing 26; the motor 21 is fixedly connected to the frame 11 and is located on the side of the frame 11; the driving sheave 22 is rotatably connected to the frame 11, is fixedly connected to the output end of the motor 21, and is located on the side of the frame 11; the driven sheave 23 is rotatably connected to the frame 11 and is located on the side of the frame 11; the V-belt 24 is sleeved on the sides of the driving sheave 22 and the driven sheave 23; the main shaft 25 is fixedly connected to the driven sheave 23, is fixedly connected to the rotor 3, and is located between the driven sheave 23 and the rotor 3; the outer ring of the bearing 26 is fixedly connected to the frame 11, and the inner ring of the bearing 26 is fixedly connected to the main shaft 25 and is located between the frame 11 and the main shaft 25. The motor 21 drives the driving sheave 22 to rotate, the driving sheave 22 drives the driven sheave 23 to rotate through the V-belt 24, the driven sheave 23 drives the main shaft 25 to rotate, the main shaft 25 drives the rotor 3 and the rotor blades 4 to rotate, and through the provided bearing 26, the main shaft 25 can rotate stably.

[0034] In this embodiment, the main shaft 25 includes a lower shaft body 251 and an upper shaft body 252; the lower shaft body 251 is fixedly connected to the driving sheave 22 and is located above the driving sheave 22; the upper shaft body 252 is detachably connected to the lower shaft body 251, is fixedly connected to the rotor 3, and is located between the lower shaft body 251 and the rotor 3. The upper shaft body 252 and the lower shaft body 251 are connected by bolts. With this segmented design of the main shaft 25, when the rotor blades 4 need to be replaced, the upper shaft body 252 can be detached from the lower shaft body 251, so that the rotor 3 and the rotor blades 4 can be taken out from the inside of the grain processor to facilitate the replacement of the rotor blades 4.

[0035] When using a vertical grain processor of the present invention, one end of the air suction pipe 16 away from the stator 6 is connected to an external air extractor. The air extractor is turned on, and rice, wheat or other grain materials to be processed are put into the feed pipe 5. By turning on the motor 21 to drive the driving sheave 22 to rotate, the driving sheave 22 drives the driven sheave 23 to rotate via the V-belt 24. The driven sheave 23 drives the main shaft 25 to rotate, and the main shaft 25 drives the rotor 3 and the rotor blades 4 to rotate. The material enters the gap between the stator 6 and the rotor 3 through the feed pipe 5. The rotor blades 4 and the stator blades 7 are arranged crosswise and at a certain angle. The rotation of the rotor blades 4 generates agitation and impact on the material, so as to thresh the residual ears in the material and break or tear sundries such as soil clods and straws. Under the action of the centrifugal force generated by the rotation of the rotor 3 and the shearing force of the rotor blades 4, the material is evenly thrown around. When the material contacts the baffle plate 14, its movement direction changes and it is scattered and obliquely thrown upward in a loose state, which is conducive to the air flow to carry away the sundries therein. The residual ears, soil clods, straws and other sundries are sucked away by the air suction pipe 16 through the gap between the shield 121 and the inner fairing 17. The clean material falls into the aggregate hopper 123 under the action of gravity and flows out of the discharge hopper 15, thus completing the processing of the material, which is greatly beneficial to the subsequent processing. In addition, the air suction pipe 16 can also be not connected. The material with impurities can be discharged from the discharge hopper 15, and the subsequent winnowing equipment is used for screening the impurities and the grain materials. A wear-resistant cast iron plate 1 27 is fixedly arranged on the inner wall of the baffle plate 14, and a wear-resistant cast iron plate is arranged on the inner wall of the shield 121 to improve the durability. By opening the shield 121, it is convenient to repair the internal structures such as the rotor blades 4 and the stator blades 7 inside the shield 121. The upper shaft body 252 and the lower shaft body 251 are connected by bolts. The main shaft 25 adopts this segmented design. When the rotor blades 4 need to be replaced, the upper shaft body 252 can be disassembled from the lower shaft body 251, so that the rotor 3 and the rotor blades 4 can be taken out from the inside of the grain processor to facilitate the replacement of the rotor blades 4. The vertical grain processor of the present invention occupies much less floor area than the horizontal machine. The material enters the grain processor by gravity and is discharged by centrifugal force and the oblique thrust of the rotor blades 4. The work is smooth and reliable without jamming or material retention. Especially in combination with the air suction pipe 16, sundries such as soil clods or straws wrapped in the material from the field or other links are broken or torn by the rotor blades 4 and the stator blades 7 and then directly sucked away by the air suction pipe 16 through the gap between the shield 121 and the inner fairing 17. Larger foreign objects will stay in the storage area in the middle of the housing assembly 1 and will not damage the rotating parts and can be taken out after shutdown, achieving multi-purpose in one machine.
