Description

Technical Field

[0001] This utility model relates to the technical field of grain dust removal equipment, and in particular to a multi-tube irregularly shaped dust collector. Background Technology

[0002] Currently, grain needs to be screened before being stored to remove dust, shriveled husks, plant leaves, straw, and other impurities, thereby improving the cleanliness of the grain, preventing mold growth due to impurities, and extending the shelf life of the grain. In the existing grain screening process, heavier impurities are screened out, while lighter impurities are collected by a dust collector. Most existing cyclone dust collectors are single-cylinder dust collectors, and impurities such as shriveled husks, plant leaves, and straw in the grain require high-powered fans to remove them. In order to ensure the dust removal effect, the power of the dust collector must be increased and the height of the dust collection cylinder must be increased, which is not conducive to transportation. Moreover, if the dust collector malfunctions, the grain screening screen cannot be used either.

[0003] Chinese invention patent CN110935239A discloses a multi-cylinder grain dust collector, which includes a fan, a housing, a first cylinder, a second cylinder, a third cylinder, a screw conveyor, and three sets of exhaust pipes. The screw conveyor has two sets of ash inlets. The bottom of the housing has three sets of cylinder mounting holes, and the top of the housing has three sets of exhaust pipe mounting holes corresponding to the cylinder mounting holes. An air inlet pipe is located on one side of the housing. The fan is mounted on the housing, and its outlet is connected to the housing via the air inlet pipe. The cylinders include components from top to bottom... The straight cylindrical section, upper conical section, and lower conical section are welded together in sequence. One end of the straight cylindrical section of one set of first cylindrical bodies and one set of second cylindrical bodies is installed on two of the three sets of cylindrical body mounting holes on the housing and communicates with the inside of the housing. One end of the lower conical section of one set of first cylindrical bodies and one set of second cylindrical bodies is installed on the screw conveyor and communicates with the inside of the screw conveyor. The first cylindrical bodies and the second cylindrical bodies are arranged in an alternating pattern. The upper conical section of the third cylindrical body is installed on the other set of cylindrical body mounting holes on the housing and communicates with the inside of the housing. The internal structure is interconnected. A set of third cylindrical bodies has a lower conical section installed on the lower conical section of either the first or second cylindrical body, and is connected to the lower conical section of either the first or second cylindrical body. Three sets of exhaust pipes are installed in three exhaust pipe mounting holes on the top of the housing. One end of each set of exhaust pipes is located inside the straight cylinder of the first, second, and third cylindrical bodies, respectively. Spiral guide vanes are provided between the straight cylinders and the exhaust pipes. Due to the different sizes of impurities in different grains, the inventors found in actual grain dust removal work that for larger impurities, the depth of the exhaust pipe inserted into the cylinder can be reduced to increase centrifugal force and improve the settling effect of large impurities. For smaller impurities, the depth of the exhaust pipe inserted into the cylinder can be increased to increase the collision and aggregation time of small impurities and improve the settling effect of small impurities. However, in the above-mentioned multi-cylinder grain dust collector, the exhaust pipe is fixedly installed inside the exhaust hole mounting hole. Therefore, the depth of the exhaust pipe inserted into the cylinder cannot be adjusted according to the size of impurities in different grains to improve the settling effect of impurities in the grain. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a multi-tube irregular-shaped dust collector to solve the technical problem in the background technology that the depth of the exhaust pipe inserted into the cylinder can not be adjusted according to the size of impurities in different grains in order to improve the settling effect of impurities in grains.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a multi-tube irregular-shaped dust collector, including a housing, with multiple cylindrical bodies connected to the interior of the housing installed at the bottom of the housing. The housing is characterized by a horizontally arranged partition dividing the upper and lower sides of the housing into an upper chamber and a lower chamber. The lower chamber has an air inlet on its side wall, communicating with the interior of the lower chamber. The upper end of each cylindrical body extends into the lower chamber and connects to the partition. A portion of the cylindrical body's side wall within the lower chamber has an air inlet hole, and the upper chamber's side wall has an exhaust port communicating with the interior of the upper chamber. Through holes are provided at positions opposite to the cylindrical bodies on the partition, and each through hole has an exhaust pipe that is movably installed vertically to adjust the depth of the exhaust pipe inserted into the cylindrical body.

[0006] Furthermore, the dust collector also includes a drive mechanism for driving the exhaust pipe to rise and fall. The drive mechanism includes a lifting plate with multiple mounting holes. The exhaust pipe is installed inside the mounting holes. A first drive plate is installed on the top of the lifting plate with a first strip-shaped drive hole. The drive mechanism also includes a drive shaft with both ends rotatably connected to both sides of the housing via bearings. A U-shaped drive part is provided on the drive shaft, which is movably disposed inside the first strip-shaped drive hole. One end of the drive shaft is connected to a drive assembly for driving its rotation.

[0007] Furthermore, the drive assembly includes a connecting rod vertically mounted on one end of the drive shaft. A handle is hinged to the end of the connecting rod away from the drive shaft. A second drive plate is mounted on the handle. The second drive plate has a second strip-shaped drive hole. The connecting rod has a first guide hole. A first guide rod is movably mounted inside the first guide hole. One end of the first guide rod passes through the second strip-shaped drive hole and is connected to a limiting block. A fixing block is mounted on the other end of the first guide rod. The fixing block and the connecting rod are connected by an elastic element. The drive assembly also includes a fixing ring mounted on one side of the housing. The fixing ring has multiple fixing grooves that match the fixing blocks in a ring shape with its central axis as the center.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, the outer diameter of the fixing ring at the end closer to the housing is larger than the outer diameter at the end farther from the housing, and the fixing groove is located on the end of the fixing ring with the smaller outer diameter.

[0010] Furthermore, the lifting plate is provided with a second guide hole, and a second guide rod is installed on the top of the partition plate. The second guide rod is movably disposed inside the second guide hole. Furthermore, the dust collector also includes a feeding mechanism, which includes a feeding pipe. The side wall of the feeding pipe is connected to the lower end of the cylinder. An auger rod is coaxially arranged inside the feeding pipe, and the auger rod is connected to a drive device for driving its rotation.

[0011] Furthermore, a sealing ring is installed inside the through hole.

[0012] Furthermore, the cylinder body includes a straight cylinder section, an upper conical cylinder section, and a lower conical cylinder section that are welded together sequentially from top to bottom.

[0013] Furthermore, the width of the air intake gradually increases towards the housing.

[0014] The beneficial effects of this utility model include: 1. Airflow can enter the box through the air inlet. The airflow inside the box can enter the cylinder through the air inlet hole. The airflow inside the cylinder can rotate between the cylinder and the exhaust pipe. The centrifugal force generated by the rotation separates the impurities in the grain from the gas. The separated impurities can be discharged through the cylinder, and the separated gas can be discharged through the exhaust pipe. At the same time, the exhaust pipe is installed inside the through hole and can be adjusted according to the size of the impurities in different grains to improve the settling effect of impurities in the grain. 2. When the handle lever is swung, it drives the second drive plate to rotate. The second drive plate can drive the first guide rod to move inside the first guide hole through the second strip-shaped drive hole, causing the fixed block to separate from the fixed ring. After the fixed block and the fixed ring are separated, rotating the handle lever can drive the drive shaft to rotate through the connecting rod. The drive shaft can drive the U-shaped drive part to rotate. The U-shaped drive part can drive the first drive plate to move up and down through the first strip-shaped drive hole. The first drive plate can drive the lifting plate to move up and down, thereby driving the exhaust pipe to move up and down to adjust the depth of the exhaust pipe inserted into the cylinder. After adjustment, the handle lever is released. Under the elastic force of the elastic element, the fixed block is inserted and fixed inside the fixed groove, thus fixing the drive shaft. This allows for easy adjustment of the depth of the exhaust pipe inserted into the cylinder. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a multi-tube irregularly shaped dust collector, such as Figure 1-3 As shown, the device includes a housing 1. Multiple cylindrical bodies 2, communicating with the interior of the housing 1, are installed at the bottom of the housing 1. A horizontal partition 3 is installed inside the housing 1, dividing the upper and lower sides of the housing 1 into an upper chamber 11 and a lower chamber 12. The side wall of the lower chamber 12 has an air inlet 13 communicating with the interior of the lower chamber 12. The width of the air inlet 13 gradually increases towards the housing 1. The upper end of each cylindrical body 2 extends into the lower chamber 12 and connects to the partition 3. A portion of the side wall of the cylindrical body 2 within the lower chamber 12 has an air inlet 211. The side wall of the upper chamber 11 has an exhaust port 14 communicating with the upper chamber 11. Through holes 3 are provided at positions opposite to the cylindrical bodies 2 on the partition 3. 1. Each through hole 31 is equipped with an exhaust pipe 4 that moves up and down inside. Airflow can enter the box 1 through the air inlet 13. The airflow inside the box 1 can enter the cylinder 2 through the air inlet 211. The airflow inside the cylinder 2 can rotate between the cylinder 2 and the exhaust pipe 4. The centrifugal force generated by the rotation separates the impurities in the grain from the gas. The separated impurities can be discharged through the cylinder 1, and the separated gas can be discharged through the exhaust pipe 4. At the same time, the exhaust pipe 4 is installed up and down inside the through hole 31. The depth of the exhaust pipe 4 inserted into the cylinder 2 can be adjusted according to the size of the impurities in different grains to improve the settling effect of impurities in the grain.

[0018] In this embodiment, a sealing ring 311 is installed inside the through hole 31. The sealing ring 311 is either a silicone ring or a rubber ring. The sealing ring 311 can seal the inner wall of the through hole 31 and the outer wall of the exhaust pipe 4 to prevent air leakage.

[0019] In this embodiment, the dust collector also includes a drive mechanism 5 for driving the exhaust pipe 4 to rise and fall. The drive mechanism 5 includes a lifting plate 51, which has multiple mounting holes 511. The exhaust pipe 4 is installed inside the mounting holes 511. A first drive plate 52 is installed on the top of the lifting plate 51, which has a first strip-shaped drive hole 521. The drive mechanism 5 also includes a drive shaft 53, which has two ends rotatably connected to the two sides of the housing 1 via bearings. The drive shaft 53 has a U-shaped drive part 531. The drive shaft 53 is installed inside the first strip-shaped drive hole 521. One end of the drive shaft 53 is connected to the drive assembly 54 for driving its rotation. The drive assembly 54 can drive the drive shaft 53 to rotate, and the drive shaft 53 can drive the U-shaped drive part 531 to rotate. The U-shaped drive part 531 can drive the first drive plate 52 to move up and down through the first strip-shaped drive hole 521. The first drive plate 52 can drive the lifting plate 51 to move up and down, thereby driving the exhaust pipe 4 to move up and down, and adjusting the depth of the exhaust pipe 4 inserted into the cylinder 2. The structure is simple and the design is reasonable.

[0020] As for the drive assembly 54, it only needs to be able to drive the drive shaft 53 to rotate. Therefore, it is not limited to a specific structure. For example, in some embodiments, the drive assembly 54 adopts one of an electric motor, a hydraulic motor, or a pneumatic motor.

[0021] In this embodiment, as Figure 4As shown, the drive assembly 54 includes a connecting rod 541 vertically mounted on one end of the drive shaft 53. A handle 542 is hinged to the end of the connecting rod 541 away from the drive shaft 53. A second drive plate 543 is mounted on the handle 542. The second drive plate 543 has a second strip-shaped drive hole 5431. The connecting rod 541 has a first guide hole 5411. A first guide rod 544 is movably mounted inside the first guide hole 5411. One end of the first guide rod 544 passes through the second strip-shaped drive hole 5431 and connects to the limiting block 545. Next, a fixing block 546 is installed at the other end of the first guide rod 544. The fixing block 546 is connected to the connecting rod 541 by an elastic element 547, which is a spring. The drive assembly 54 also includes a fixing ring 548 installed on one side of the housing 1. The central axis of the fixing ring 548 is on the same straight line as the central axis of the connecting rod 541. The fixing ring 548 has a plurality of fixing grooves 5481 evenly arranged in a ring with its central axis as the center. When the handle 542 is swung, the handle 542 can drive the second drive plate 543 to rotate. When the second drive plate 543 moves, it can drive the first guide rod 544 to move inside the first guide hole 5411 through the second strip-shaped drive hole 5431, causing the fixing block 546 to separate from the fixing ring 548. After the fixing block 546 separates from the fixing ring 548, the handle 542 is rotated. The handle 542 can drive the drive shaft 53 to rotate through the connecting rod 541. The drive shaft 53 can drive the U-shaped drive part 531 to rotate. The U-shaped drive part 531 can drive the first drive plate 52 to move up and down through the first strip-shaped drive hole 521. A drive plate 52 can drive the lifting plate 51 to move up and down, thereby driving the exhaust pipe 4 to move up and down, adjusting the depth of the exhaust pipe 4 inserted into the cylinder 2. After adjustment, the handle 542 is released, and under the elastic force of the elastic element 547, the fixing block 546 is inserted and fixed in the fixing groove 5481, thus fixing the drive shaft 53. This allows for fixing the depth of the exhaust pipe 4 inserted into the cylinder 2, making the operation convenient and allowing for easy adjustment of the depth of the exhaust pipe 4 inserted into the cylinder 2.

[0022] It should be noted that the outer diameter of the fixing ring 548 near the housing 1 is larger than the outer diameter of the end away from the housing 1, and the fixing groove 5481 is located at the end of the fixing ring 548 with the larger outer diameter.

[0023] It should be noted that the lifting plate 51 is provided with a second guide hole 512, and the top of the partition plate 3 is equipped with a second guide rod 55. The second guide rod 55 is movably disposed inside the second guide hole 512. Through the cooperation of the second guide rod 55 and the second guide hole 512, the lifting plate 51 can move up and down stably, thereby stably adjusting the depth of the exhaust pipe 4 inserted into the cylinder 2.

[0024] In this embodiment, the dust collector also includes a feeding mechanism 6, which includes a feeding pipe 61. The side wall of the feeding pipe 61 is connected to the lower end of the cylinder 2. An auger rod 62 is coaxially provided inside the feeding pipe 61. The auger rod 62 is connected to a drive device 63 for driving its rotation. The drive device 63 is one of an electric motor, a hydraulic motor, or a pneumatic motor. Impurities discharged from inside the cylinder 1 can enter the feeding pipe 61. The drive device 63 can drive the auger rod 62 to rotate, so as to discharge the impurities inside the feeding pipe 61.

[0025] It should be noted that the cylinder 2 includes a straight cylinder section 21, an upper conical cylinder section 22 and a lower conical cylinder section 23 that are welded together from top to bottom. The air inlet 211 is located on the straight cylinder section 21. The lower conical cylinder 23 gradually tilts from top to bottom toward the axis of the feeding mechanism 6, making the lower conical cylinder section 23 arc-shaped. This increases the airflow resistance at the lower conical cylinder section 23, slows down the airflow speed, and prevents impurities from being discharged through the exhaust pipe 4.

[0026] Specific principle: Before removing impurities from the grain, the depth of the exhaust pipe 4 inserted into the cylinder 2 is adjusted according to the size of the impurities in different grains. Specifically, this is achieved by swinging the handle 542, which drives the second drive plate 543 to rotate. The second drive plate 543 can drive the first guide rod 544 to move inside the first guide hole 5411 through the second strip-shaped drive hole 5431, causing the fixed block 546 to separate from the fixed ring 548. After the fixed block 546 separates from the fixed ring 548, rotating the handle 542 drives the drive shaft 53 to rotate through the connecting rod 541. The drive shaft 53 drives the U-shaped drive part 531 to rotate, and the U-shaped drive part 531 can drive the first drive plate 52 to move up and down through the first strip-shaped drive hole 521. The first drive plate 52 can then drive the lifting plate 5... 1. The handle 542 is moved up and down, thereby driving the exhaust pipe 4 to move up and down, adjusting the depth of the exhaust pipe 4 inserted into the cylinder 2. After adjustment, the handle 542 is released. Under the elastic force of the elastic element 547, the fixing block 546 is inserted and fixed in the fixing groove 5481, thus fixing the drive shaft 53, thereby fixing the depth of the exhaust pipe 4 inserted into the cylinder. When removing impurities from the grain, the airflow is introduced into the box 1 through the air inlet 13. The airflow entering the box 1 can enter the cylinder 2 through the air inlet 211. The airflow entering the cylinder 2 can rotate between the cylinder 2 and the exhaust pipe 4. The centrifugal force generated by the rotation separates the impurities in the grain from the gas. The separated impurities can be discharged through the cylinder 1, and the separated gas can be discharged through the exhaust pipe 4.

[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
