Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and particularly to a dust removal device for the preliminary screening and processing of corn seeds. Background Art

[0002] Traditional dust removal methods, such as simple bag dust removal, have limited filtration efficiency and are difficult to meet the strict dust emission standards in corn seed processing workshops. Their ability to capture fine dust is weak. Although cyclone dust removal can handle larger particle dust, it has poor effect on dust with smaller particle sizes, and it is prone to clogging when dealing with high-concentration dust.

[0003] The patent with the publication number CN210814436U relates to a dust removal device for corn preliminary screening and processing, belonging to the technical field of corn processing. The dust removal device for corn preliminary screening and processing includes a dust removal component, a filtering component, and a water pumping component. The dust removal component includes a dust removal outer shell, an air inlet pipe, an exhaust pipe, and a first gate valve. The air inlet pipe is fixedly communicated with one side of the dust removal outer shell. The filtering component includes a filtering outer shell and a filter screen. The water pumping component includes a water pump and a water spraying pipe component. Water is stored in the dust removal outer shell. The air containing dust and corn bran enters the water through the air inlet pipe. The dust and corn bran are filtered by the water and retained in the water. The air filtered by the water is discharged through the exhaust pipe, thereby reducing the amount of dust and corn bran entering the air in the processing workshop with the wind. This device effectively improves the problem that the air in the processing workshop is prone to having more dust during the corn preliminary screening process, reduces environmental pollution, and reduces the harm of dust to the human body. However, when discharging the corn bran and dust in the water, this device is prone to storing too much absorbed corn bran in the filtering component of the device, and then it is easy to cause blockage problems in the exhaust pipe and the water changing port. Therefore, a dust removal device for the preliminary screening and processing of corn seeds is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dust removal device for the preliminary screening and processing of corn seeds in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a dust removal device for primary screening and processing of corn seeds, including a walking platform. The inner wall of the walking platform is fixedly connected with a funnel. The inner wall of the funnel is fixedly connected with a conveying pipe. The bottom of the conveying pipe is fixedly communicated with a flow pipe. The top of the walking platform is fixedly connected with a U-shaped frame. The top of the U-shaped frame is fixedly connected with a water tank. A flow groove is installed on the inner wall of the U-shaped frame. A motor is fixedly connected to the front of the U-shaped frame. The left side of the flow groove is fixedly communicated with a connecting pipe through a water pump. An air suction fan is installed on the inner wall of the flow groove. The output end of the motor is fixedly connected with a reciprocating lead screw. A moving frame is movably connected to the circumferential surface of the reciprocating lead screw. A filter box is installed at the rear of the moving frame. An anti-blocking mechanism for preventing blockage is arranged on the inner wall of the flow groove. A quick-disassembly mechanism for quick disassembly and assembly is arranged on the inner wall of the moving frame. A suction flow plate is rotatably connected to the inner wall of the filter box. The central axis of the suction flow plate is fixedly connected with a transmission wheel. The inner wall of the water tank is fixedly communicated with the circumferential surface of the connecting pipe, and the connecting pipe is used to convey the dust-removed water to the water tank. The circumferential surface of the reciprocating lead screw is rotatably connected with the inner wall of the U-shaped frame. The circumferential surface of the reciprocating lead screw is rotatably connected with the inner wall of the flow groove. The surface of the moving frame is slidably connected with the inner wall of the flow groove, and the flow groove is used for limiting during the operation of the moving frame. The inner wall of the flow groove is in contact with the circumferential surface of the transmission wheel, and the flow groove will provide friction for the transmission wheel during the operation of the transmission wheel. The suction pipe of the air suction fan is fixedly communicated with the inner wall of the flow groove, so that bran can be sucked into the inside of the flow groove, and thus the dust during the transportation of corn can be effectively treated to reduce the dust content in the workshop. The bran and dust floating on the water surface can also be collected, effectively avoiding the situation that a large amount of bran accumulates in the device, resulting in excessive accumulation of bran blocking the exhaust port and water replacement port, effectively improving the service life of the device and the treatment effect on bran. At the same time, the bran on the water surface can be quickly sucked into the inside of the flow groove, further improving the collection effect of bran. The rotation of the suction flow plate reduces the situation of bran omission.

[0006] Preferably, the anti-blocking mechanism includes a filter plate fixedly connected to the inner wall of the flow channel. A chamfer block 1 is fixedly connected to the inner wall of the flow channel. A lifting plate is slidably connected to the inner wall of the chamfer block 1. A push plate is fixedly connected to the left side of the lifting plate. A pushing frame is fixedly connected to the front part of the moving frame. An inclined plate is fixedly connected to the front part of the lifting plate. A connecting block 1 is fixedly connected to the rear part of the filter box. A scraper is fixedly connected to the inner wall of the connecting block 1. The right side of the filter plate is in contact with the left side of the push plate. The filter plate filters the water after dust removal. The pushing frame will contact the inclined plate when moving. The inner wall of the scraper is in contact with the inner wall of the flow channel. The scraper will handle the attached impurities, so as to stir the corn bran in the water. Thus, when changing the water, the impurities brought to the surface of the filter plate by the fluidity of the water can be cleaned, avoiding the situation that when changing the water, the water level drops, resulting in the inability to collect the impurities in the water, and a large amount of impurities in the water accumulate on the surface of the filter plate, leading to the inability to change the water and the inability to perform dust removal normally. At the same time, the bran and dust attached to the inner wall of the flow channel can be scraped off, preventing the corn bran from getting stuck in the gap between the filter box and the inner wall of the flow channel during the movement of the filter box, resulting in jamming during the movement of the filter box and affecting the normal collection of corn bran.

[0007] Preferably, the quick-release mechanism includes a limit plate fixedly connected to the inner wall of the moving frame. A chamfer block 2 is fixedly connected to the inner wall of the flow channel. A cylinder is fixedly connected to the top of the chamfer block 2. A convex block is fixedly connected to the right side of the filter plate. A connecting block 2 is fixedly connected to the front part of the filter box. A sliding rod is slidably connected to the inner wall of the connecting block 2 through a spring. A clamping plate is fixedly connected to the inner wall of the sliding rod. A pulling plate is fixedly connected to the circumferential surface of the sliding rod. The output end of the cylinder is fixedly connected to a connecting rod. A knocking rod is slidably connected to the inner wall of the connecting rod through a spring. The left side of the knocking rod is in contact with the right side of the convex block. The knocking rod is used to vibrate the impurities in the holes of the filter plate. The inner wall of the limit plate is in contact with the surface of the clamping plate. The clamping plate locks the filter box, which can vibrate the dirt blocking the holes in the inner wall of the filter plate, improving the passing rate of water flow, accelerating the water flow replacement speed, and then enabling the device to quickly enter the dust removal work. At the same time, the limit between the clamping plate and the limit plate can be released, so that the filter box can be quickly disassembled, facilitating the cleaning of the filter box by workers.

[0008] Adopting the above technical solutions, the present invention can bring the following beneficial effects: 1. The dust removal device for the preliminary screening and processing of corn seeds can suck bran into the inside of the flow tank through the coordinated operation among the walking platform, funnel, conveying pipe, circulation pipe, U-shaped frame, water tank, flow tank, motor, connecting pipe, suction fan, reciprocating lead screw, moving frame, filter box, suction flow plate, and transmission wheel. Thus, it can effectively handle the dust during the corn transportation process to reduce the dust content in the workshop. It can also collect the bran and dust floating on the water surface, effectively avoiding the situation where a large amount of bran accumulates inside the device, blocking the exhaust port and water replacement port. This can effectively improve the service life of the device and the treatment effect on bran. At the same time, it can quickly suck the bran on the water surface into the inside of the flow tank, further improving the collection effect of bran, and reducing the omission of bran through the rotation of the suction flow plate.

[0009] 2. The dust removal device for the preliminary screening and processing of corn seeds can stir the corn bran in the water through the coordinated operation among the filter plate, chamfer block one, lifting plate, and push plate. Therefore, when changing the water, it can clean the impurities brought to the surface of the filter plate by the fluidity of the water flow, avoiding the situation where the water level drops during water replacement, resulting in the inability to collect the impurities in the water, and a large amount of impurities in the water accumulate on the surface of the filter plate, making it impossible to change the water and unable to carry out dust removal normally.

[0010] 3. The dust removal device for the preliminary screening and processing of corn seeds can scrape off the bran and dust attached to the inner wall of the flow tank through the coordinated operation among the pushing frame, inclined plate, connecting block one, and scraper, avoiding the situation where the corn bran gets stuck in the gap between the filter box and the inner wall of the flow tank during the movement of the filter box, resulting in jamming during the movement of the filter box and affecting the normal collection of corn bran.

[0011] 4. The dust removal device for the preliminary screening and processing of corn seeds can shake off the dirt blocking the holes in the inner wall of the filter plate through the coordinated operation among the limiting plate, chamfer block two, cylinder, and convex block, improving the passing rate of water flow, accelerating the water flow replacement speed, and enabling the device to quickly be put into the dust removal work.

[0012] 5. The dust removal device for the preliminary screening and processing of corn seeds can release the limit between the clamping plate and the limiting plate through the coordinated operation among the connecting block two, sliding rod, clamping plate, pulling plate, connecting rod, and knocking rod, thus quickly disassembling the filter box for the convenience of workers to clean the filter box.

Specific embodiments

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] Please refer to Figures 1 - 10, an embodiment of the present invention is: a dust removal device for the preliminary screening and processing of corn seeds, including a walking platform 1. The inner wall of the walking platform 1 is fixedly connected with a funnel 2. The inner wall of the funnel 2 is fixedly connected with a conveying pipe 3. The bottom of the conveying pipe 3 is fixedly communicated with a flow pipe 4. The top of the walking platform 1 is fixedly connected with a U-shaped frame 5. The top of the U-shaped frame 5 is fixedly connected with a water tank 6. A flow groove 7 is installed inside the U-shaped frame 5. The front part of the U-shaped frame 5 is fixedly connected with a motor 8. The left side of the flow groove 7 is fixedly communicated with a connecting pipe 9 through a water pump. An air suction fan 10 is installed inside the flow groove 7. The output end of the motor 8 is fixedly connected with a reciprocating lead screw 11. A moving frame 12 is movably connected to the circumferential surface of the reciprocating lead screw 11. A filter box 13 is installed at the rear of the moving frame 12. An anti-blocking mechanism 16 for preventing blockage is arranged inside the flow groove 7. A quick-disassembly mechanism 17 for quick disassembly and assembly is arranged inside the moving frame 12. A suction flow plate 14 is rotatably connected to the inner wall of the filter box 13. The central axis of the suction flow plate 14 is fixedly connected with a transmission wheel 15. The inner wall of the water tank 6 is fixedly communicated with the circumferential surface of the connecting pipe 9, and the connecting pipe 9 is used to convey the dust-removed water to the water tank 6. The circumferential surface of the reciprocating lead screw 11 is rotatably connected to the inner wall of the U-shaped frame 5. The circumferential surface of the reciprocating lead screw 11 is rotatably connected to the inner wall of the flow groove 7. The surface of the moving frame 12 is slidably connected to the inner wall of the flow groove 7, and the flow groove 7 is used for limiting during the operation of the moving frame 12. The inner wall of the flow groove 7 is in contact with the circumferential surface of the transmission wheel 15, and the flow groove 7 will provide friction for the transmission wheel 15 during the operation of the transmission wheel 15. The suction pipe of the air suction fan 10 is fixedly communicated with the inner wall of the flow groove 7.

[0017] During the process of preliminary screening of corn, the corn seeds enter the funnel 2 through the flow pipe 4. At this time, during the falling process of the corn, the air suction fan 10 is started to adsorb the bran and dust mixed in the corn seeds, so as to suck the bran into the inside of the flow groove 7. Furthermore, the dust during the corn transportation process can be effectively processed to reduce the dust content in the workshop. When the bran is sucked into the inner wall of the flow groove 7, the bran will float on the surface of the water inside the flow groove 7. At this time, the motor 8 is started and drives the reciprocating lead screw 11 to rotate. The reciprocating lead screw 11 rotates to drive the moving frame 12 to move through the threads provided on the surface. The moving frame 12 moves to drive the filter box 13 to move, so that the bran machine dust floating on the water surface can be collected, effectively avoiding the situation that a large amount of bran accumulates inside the device, resulting in excessive accumulation of bran blocking the exhaust port and the water replacement port, and effectively improving the service life of the device and the treatment effect on bran.

[0018] When collecting bran, the filter box 13 moves to drive the suction flow plate 14 to move. The movement of the suction flow plate 14 drives the transmission wheel 15 to move. During the movement of the transmission wheel 15, friction is generated with the inner wall of the flow groove 7, enabling the transmission wheel 15 to rotate on its own. The rotation of the transmission wheel 15 drives the suction flow plate 14 to rotate, so that the bran on the water surface can be quickly sucked into the interior of the flow groove 7, further improving the collection effect of bran and reducing the situation of bran leakage through the rotation of the suction flow plate 14.

[0019] Overall working principle: During the initial screening of corn, the suction fan 10 is started to adsorb the bran and dust mixed in the corn seeds and suck the bran into the interior of the flow groove 7, effectively treating the dust during the corn transportation process to reduce the dust content in the workshop. The motor 8 is started to drive the reciprocating lead screw 11 to rotate, preventing the bran from accumulating too much and causing blockage, effectively improving the service life of the device and the treatment effect of bran. The rotation of the transmission wheel 15 drives the suction flow plate 14 to rotate, so that the bran on the water surface can be quickly sucked into the interior of the flow groove 7, further improving the collection effect of bran and reducing the residue of bran.

[0020] The anti-blocking mechanism 16 includes a filter plate 161, which is fixedly connected to the inner wall of the flow groove 7. A chamfer block 162 is fixedly connected to the inner wall of the flow groove 7. A lifting plate 163 is slidably connected to the inner wall of the chamfer block 162. A push plate 164 is fixedly connected to the left side of the lifting plate 163. A pushing frame 165 is fixedly connected to the front part of the moving frame 12. An inclined plate 166 is fixedly connected to the front part of the lifting plate 163. A connecting block 167 is fixedly connected to the rear part of the filter box 13. A scraper 168 is fixedly connected to the inner wall of the connecting block 167. The right side of the filter plate 161 is in contact with the left side of the push plate 164, and the filter plate 161 will filter the water after dust removal. The pushing frame 165 will contact the inclined plate 166 during movement. The inner wall of the scraper 168 is in contact with the inner wall of the flow groove 7, and the scraper 168 will handle the attached impurities.

[0021] When processing wheat bran, the moving frame 12 moves to drive the pushing frame 165 to move. During the movement of the pushing frame 165, it will contact the bottom of the inclined plate 166 and exert a squeezing force on the inclined plate 166, thereby forcing the inclined plate 166 to move upward. The upward movement of the inclined plate 166 drives the lifting plate 163 to move upward. When the lifting plate 163 moves, it will contact the first chamfered block 162 and limit it, so that the lifting plate 163 can move smoothly. The upward movement of the lifting plate 163 drives the pushing plate 164 to move upward, so as to stir the corn bran in the water, so that when changing water, the impurities brought to the surface of the filter plate 161 by the fluidity of the water flow can be cleaned, and it can be avoided that when changing water, the water level drops and the impurities in the water cannot be collected, resulting in a large amount of impurities in the water accumulating on the surface of the filter plate 161, making it impossible to change water and impossible to carry out dust removal normally.

[0022] When collecting corn bran, the filter box 13 moves to drive the first connecting block 167 to move. The movement of the first connecting block 167 drives the scraper 168 to move. The movement of the scraper 168 will contact the inner wall of the flow channel 7, so that the bran and dust attached to the inner wall of the flow channel 7 can be scraped off, and it can be avoided that the corn bran gets stuck in the gap between the filter box 13 and the inner wall of the flow channel 7 during the movement of the filter box 13, resulting in jamming during the movement of the filter box 13 and affecting the normal collection of corn bran.

[0023] Overall working principle: When processing wheat bran, the moving frame 12 moves to drive the pushing frame 165 to move. During the movement of the pushing frame 165, it will contact the bottom of the inclined plate 166, so that when exchanging the water in the water tank 6 with the water in the flow channel 7, it can be avoided that the impurities in the water in the flow channel 7 block the water exchange port during water change. When collecting corn bran, the scraper 168 moves and contacts the inner wall of the flow channel 7, and can scrape off the bran attached to the inner wall of the flow channel 7, avoiding affecting the normal operation of the device.

[0024] Please refer to Figures 1 - 10, on the basis of the above embodiments, in another embodiment of the present invention, the quick-release mechanism 17 includes a limit plate 171 fixedly connected to the inner wall of the moving frame 12. A chamfer block two 172 is fixedly connected to the inner wall of the flow groove 7. A cylinder 173 is fixedly connected to the top of the chamfer block two 172. A convex block 174 is fixedly connected to the right side of the filter plate 161. A connecting block two 175 is fixedly connected to the front part of the filter box 13. A sliding rod 176 is slidably connected to the inner wall of the connecting block two 175 through a spring. A clamping plate 177 is fixedly connected to the inner wall of the sliding rod 176. A pulling plate 178 is fixedly connected to the circumferential surface of the sliding rod 176. The output end of the cylinder 173 is fixedly connected to a connecting rod 179. A 1710 is slidably connected to the inner wall of 179 through a spring. The left side of the knocking rod 1710 is in contact with the right side of the convex block 174, and the knocking rod 1710 is used to vibrate the impurities in the holes of the filter plate 161. The inner wall of the limit plate 171 is in contact with the surface of the clamping plate 177, and the clamping plate 177 locks the filter box 13.

[0025] When changing the water, the cylinder 173 is started to drive the connecting rod 179 to move. The movement of the connecting rod 179 drives the knocking rod 1710. During the movement of the knocking rod 1710, it will come into contact with the convex block 174 and exert an extrusion force on the knocking rod 1710, causing the knocking rod 1710 to move to the right. A waterproof shell is provided at the top of the chamfer block two 172 to prevent water from entering the cylinder 173 during operation, and the push plate 164 is placed out of alignment with the cylinder 172 so that the push plate 164 can move normally. When the knocking rod 1710 passes over the convex block 174, the knocking rod 1710 generates an impact force on the surface of the filter plate 161 through the spring, so as to be able to vibrate the dirt blocked in the holes on the inner wall of the filter plate 161, improve the passing rate of water flow, accelerate the replacement speed of water flow, and then enable the device to quickly be put into the dust removal work. At the same time, after too much corn bran is collected inside the filter box 13, pull the pulling plate 178 to drive the sliding rod 176 to move upward. The upward movement of the sliding rod 176 drives the clamping plate 177 to move upward, so as to release the limit between the clamping plate 177 and the limit plate 171, and thus the filter box 13 can be quickly disassembled, facilitating the worker to clean the filter box 13.

[0026] Overall working principle: When changing the water, when the knocking rod 1710 passes over the convex block 174, the knocking rod 1710 generates an impact force on the surface of the filter plate 161 through the spring, which can vibrate the dirt blocked in the holes on the inner wall of the filter plate 161, improve the passing rate of water flow, and then enable the device to quickly be put into the dust removal work. At the same time, after too much corn bran is collected inside the filter box 13, pull the pulling plate 178 to drive the sliding rod 176 to move upward, and the filter box 13 can be quickly disassembled, facilitating the worker to clean the filter box 13 to reduce the cleaning time of the device.

The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using the prior art.
