Description

Technical Field

[0001] This utility model relates to the field of grain conveying equipment, and in particular to a grain elevator with dust removal function. Background Technology

[0002] A grain elevator is a mechanical device used for vertically transporting grain. Its main function is to lift grain from a lower position to a higher position, facilitating grain storage, processing, loading, and unloading operations. For example, in large grain silos, it lifts grain scattered on the ground to storage silos at the top of the warehouse; in grain processing plants, it lifts raw grain from the feeding area to the floor where the processing equipment is located.

[0003] When lifting and conveying grain, the large amount of dust generated during the dumping and flow of grain directly permeates the workplace, reducing visibility around the feeding point. In this environment, it is difficult for operators to clearly observe the equipment's operation, thus affecting normal work efficiency, increasing the probability of operational errors and safety accidents, and impacting flour quality, reducing its purity and taste. When installing a grain elevator, without a lifting pulley system, it is difficult to accurately place the elevator in the correct position, requiring manual labor or other large equipment for dragging. This is not only inefficient but may also damage the equipment. Furthermore, during later equipment layout adjustments or maintenance, it is difficult to move the elevator, leading to grain spillage in the buckets or uneven stress on the conveyor belt, accelerating component wear. Maintenance personnel may need to lie on the ground or use special tools to operate it, increasing the difficulty and time cost of maintenance. Utility Model Content

A second discharge pipe is fixedly connected to the bottom right sidewall of the top box. A motor is installed inside the housing, and a rotating rod is fixedly connected to the output end of the motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its feed hopper, dust collection box, pump, three-way pipe, collection box, and first guide plate, solves the problems that affect normal working efficiency, increase the probability of operational errors and safety accidents, and affect flour quality, reducing flour purity and taste. When grain enters the feed hopper, the flow and impact of the material generate a large amount of dust. At this time, the pump starts, connected to the square tube through the first connecting pipe, creating a negative pressure area in the middle of the feed hopper. The dust collection box is connected to the square tube through the outer connecting pipe. Under the suction of the pump, the dust generated in the feed hopper is sucked into the dust collection box, and then extracted by the pump through the square tube and the first connecting pipe. Furthermore, the first guide plate on the top of the dust collection box prevents grain from entering the dust collection box and causing blockage of the suction port when grain is added. This effectively reduces dust pollution to other equipment and stored grain, reduces wear on parts caused by dust friction, and extends the service life of the equipment.

[0014] 2. The design, including the base, pulleys, electric push rod, second connecting block, and coupling block, solves the problems of grain spillage in the bucket or uneven conveyor belt stress, which accelerates component wear and may require maintenance personnel to lie on the ground or use special tools, increasing maintenance difficulty and time costs. By activating the electric push rod, its telescopic end extends downwards. Because the outer side of the telescopic end of the electric push rod is fixedly connected to the second connecting block, and the left and right sides of the second connecting block are fixedly connected to the second sliders, which are slidably connected in the slots on the front and rear sides of the second guide plate, the telescopic end of the electric push rod maintains a straight line during its up-and-down movement, preventing deviation or wobbling. This ensures the smoothness and accuracy of the movement, effectively improving the equipment's adaptability to different sites, ensuring efficient cooperation with upstream and downstream equipment, and reducing time and labor costs during installation.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 5 As shown: A grain elevator with dust removal function includes a base plate 1. A first support frame 2 is fixedly connected to the top of the upper side wall of the base plate 1. The base plate 1 provides bottom support for the top device, and the first support frame 2 supports and fixes the feeding hopper 3 and other devices. The feeding hopper 3 is connected through the inside of the first support frame 2. A dust collection box 4 is fixedly connected to the top of the feeding hopper 3. A first guide plate 5 is fixedly connected to the top of the dust collection box 4. When grain is conveyed to the feeding hopper 3, a large amount of dust is generated during the process of grain entering the feeding hopper 3 due to the flow and impact of the material. The dust collection box 4 is used to absorb the generated dust. In addition, the first guide plate 5 on the top of the dust collection box 4 prevents the suction port from being blocked when grain enters the dust collection box 4.

[0031] A pump 8 is installed on the left side of the upper side wall of the first support frame 2. The input end of the pump 8 is fixedly connected to a first connecting pipe 10. The right end of the first connecting pipe 10 is connected to a square pipe 6. The inner wall of the square pipe 6 is fixedly connected to the middle of the feed hopper 3. The outer side of the dust collection box 4 is connected to connecting pipes 7. The bottom ends of multiple connecting pipes 7 are connected to the top wall of the square pipe 6. By starting the pump 8 at the top of the first support frame 2, the first connecting pipe 10 at the output end of the pump 8 is connected to the square pipe 6, forming a negative pressure area in the middle of the feed hopper 3. The dust collection box 4 is connected to the square pipe 6 through the connecting pipes 7 on the outside. Under the suction of the pump 8, the dust generated in the feed hopper 3 is sucked into the dust collection box 4, and then extracted by the pump 8 through the square pipe 6 and the first connecting pipe 10.

[0032] The top two output ends of the pump 8 are fixedly connected to a triple tube 11. The left end of the triple tube 11 is connected to a second connecting tube 12. The bottom end of the second connecting tube 12 is threaded to a collection box 13. The dust sucked up is transferred to the inside of the collection box 13 through the second connecting tube 12 via the triple tube 11 on the top two output ends of the pump 8.

[0033] The right side wall of the collection box 13 is fixedly connected to a first slider 14, and the left side wall of the first support frame 2 is fixedly connected to a support plate 9. The left side wall of the support plate 9 is fixedly connected to a first guide rail plate 15. A limit plate is fixedly connected to the bottom of each of the two first guide rail plates 15. The interior of each of the two first sliders 14 is slidably connected to the interior of the first guide rail plate 15. The support plate 9 is used to fix the first guide rail plate 15 to the left side wall of the first support frame 2, providing support and fixation. During installation, the first slider 14 on the right side of the collection box 13 slides into the support plate 15. The first guide plate 15 is used to prevent the first slider 14 from falling off the first guide plate 15 by a limiting plate on the bottom of the first guide plate 15, and to support and fix the first slider 14 on the left side wall of the first support frame 2. When disassembly and cleaning are required, the second connecting pipe 12 can be twisted from the top of the collection box 13 to disassemble it. The collection box 13 and the first slider 14 can be removed from the first guide plate 15 to clean the dust and other debris inside the collection box 13.

[0034] A second guide plate 16 is fixedly connected inside the feed hopper 3, and a guide block 17 is fixedly connected to the bottom wall inside the feed hopper 3. A first discharge pipe 18 is connected through the bottom right side of the feed hopper 3, and a diversion grid plate 19 is fixedly connected inside the right side of the first discharge pipe 18. The second guide plate 16 inside the feed hopper 3 guides the grain, allowing it to move more smoothly to the bottom. The guide block 17 further assists the grain in converging into the first discharge pipe 18. In addition, the diversion grid plate 19 on the right side of the first discharge pipe 18 can perform preliminary diversion and sorting of the grain about to flow out, so that the grain enters the interior of the conveying hopper 32.

[0035] like Figure 1 - Figure 6 As shown, a housing 20 is fixedly connected to the right side of the upper side wall of the base plate 1, and a second support frame 21 is fixedly connected to the right side of the upper side wall of the base plate 1. The top of the second support frame 21 is located at the bottom right side of the housing 20. The housing 20 provides external protection for the internal device, and the second support frame 21 on the top right side of the base plate 1 provides bottom support for the right side wall of the housing 20. A protective box 22 is fixedly connected to the bottom of the front side wall of the housing 20, and a top box 23 is fixedly connected to the top of the housing 20. A second discharge pipe 24 is fixedly connected to the bottom right side wall of the top box 23. The top box 23 is used to place the grain that is brought up, and the grain is discharged through the second discharge pipe 24 at the bottom right side of the top box 23. In addition, the arc shape on the right side of the top box 23 can achieve a guiding effect, so that the grain can accurately enter the interior of the second discharge pipe 24.

[0036] A motor 25 is housed inside the outer casing 20, which provides external protection for the motor 25. A rotating rod 26 is fixedly connected to the output end of the motor 25. The rear end of the rotating rod 26 is rotatably connected inside the outer casing 20. First gears 27 are fixedly connected to both ends of the rotating rod 26. When the motor 25 is started, its output end drives the rotating rod 26 to rotate. During rotation, the rear end of the rotating rod 26 rotates against the rear inner wall of the outer casing 20, providing support and improving the stability of the rotating rod 26 during rotation. The first gears 27 fixed to both ends of the rotating rod 26 rotate synchronously.

[0037] like Figure 6 - Figure 8As shown, connecting rods 28 are rotatably connected to the front and rear sides of the interior of the outer casing 20. Second gears 29 are fixedly connected to both ends of the connecting rods 28. Racks 30 are provided on both the front and rear sides of the interior of the outer casing 20. The outer sides of the two first gears 27 and the second gear 29 are meshed with the interior of the two racks 30. Connecting rings 31 are fixedly connected to the outer sides of the two racks 30. The first gear 27 meshes with the rack 30, and the second gear 29 also meshes with the rack 30 and rotates inside the outer casing 20 via the connecting rods 28, supporting the top of the rack 30. When the first gear 27 rotates, the rack 30 begins to move linearly due to the interaction of the first gear 27, the second gear 29, and the rack 30. The connecting rings 31 fixed to the outer sides of the rack 30 also move along with the rack 30.

[0038] Both connecting rings 31 are equipped with conveying buckets 32 inside. Bolts 34 are connected through the front and rear side walls of multiple conveying buckets 32. First connecting blocks 33 are fixedly connected to the front and rear side walls of multiple conveying buckets 32. The other end of each pair of bolts 34 is threaded to the inner wall of a connecting ring 31. By using bolts 34 to penetrate the front and rear side walls of the conveying buckets 32 and the first connecting blocks 33, the conveying buckets 32 are fixed in the inner wall of the connecting ring 31, thereby driving the conveying buckets 32 to operate.

[0039] As shown above, when the conveying hopper 32 passes through the feeding area, which corresponds to the discharge position of the feeding hopper 3, the grain falls from the feeding hopper 3 into the conveying hopper 32 through the first discharge pipe 18. The conveying hopper 32, filled with grain, moves upward along the inside of the outer shell 20 under the drive of the connecting ring 31. When it moves to the top and near the top box 23, the grain is poured from the conveying hopper 32 into the top box 23 due to the change in the direction of movement of the conveying hopper 32, and then flows out through the second discharge pipe 24 at the bottom of the right side wall of the top box 23.

[0040] like Figure 9 - Figure 11 As shown, base plates 35 are fixedly connected to the bottom wall of the base plate 1. Anti-slip pads 36 are fixedly connected to the outer bottom of the four base plates 35. The base plates 35 provide bottom support for the device on top, and the anti-slip pads 36 make contact with the ground to prevent the device from sliding during use.

[0041] Each of the four bases 35 has a pulley 37 inside. A fixing ring 38 is fixedly connected to the top wall of each base 35. An electric push rod 39 is installed inside each fixing ring 38. Two second guide rail plates 40 are fixedly connected to the left and right side walls of each base 35. A second connecting block 41 is fixedly connected to the outer side of the telescopic end of each electric push rod 39. Second sliders 42 are fixedly connected to the left and right sides of each second connecting block 41. The other side of every two second sliders 42 is slidably connected to the front and rear slots of a second guide rail plate 40. When the grain elevator needs to be moved, the electric push rod 39 is activated, and its telescopic end begins to extend downwards. Because the outer side of the telescopic end of the electric push rod 39 is fixedly connected to the second connecting block 41, and the left and right sides of the second connecting block 41 are fixedly connected to the second sliders 42, and the second sliders 42 are slidably connected in the front and rear slots of the second guide rail plate 40, it is ensured that the telescopic end of the electric push rod 39 maintains a straight line during its up and down movement, without deviation or wobbling.

[0042] Each of the four electric push rods 39 has a fixed connecting block 43 at its bottom extension end. The bottom of each of the four connecting blocks 43 is fixedly connected to the upper side wall of the pulley 37. As the extension end of the electric push rod 39 moves downward, the connecting block 43 fixedly connected to its bottom drives the pulley 37 to move downward. When the pulley 37 descends to contact the ground and slightly lifts the base 35, causing the anti-slip pad 36 to detach from the ground, the weight of the grain elevator is borne by the pulley 37. Through the rolling action of the pulley 37, the operator can easily push the grain elevator to move on the ground, realizing convenient transfer of the equipment.

[0043] It should be noted that this utility model is a grain elevator with dust removal function. First, the pump 8, motor 25, and electric push rod 39 are connected to an external power source and control terminal to supply power and control the device.

[0044] At the start of the grain lifting operation, the grain is conveyed to the feed hopper 3. During the process of the grain entering the feed hopper 3, a large amount of dust is generated due to the flow and impact of the material. At this time, the suction pump 8 is activated, which is connected to the square tube 6 via the first connecting pipe 10, creating a negative pressure area in the middle of the feed hopper 3. The dust collection box 4 is connected to the square tube 6 via the outer connecting pipe 7. Under the suction force of the suction pump 8, the dust generated in the feed hopper 3 is sucked into the dust collection box 4, and then extracted by the suction pump 8 through the square tube 6 and the first connecting pipe 10. Additionally, the first guide plate 5 at the top of the dust collection box 4 prevents the suction port from becoming blocked when grain is fed into it.

[0045] The dust-laden air drawn by pump 8 is split through a three-way pipe 11, with a portion entering the collection box 13 via the second connecting pipe 12. The collection box 13 can be disassembled and cleaned via the threaded second connecting pipe 12. The collection box 13 is stably positioned with the cooperation of the first guide plate 15 and the first slider 14, and can be easily slid out for maintenance when needed. A limiting plate prevents it from slipping excessively. Inside the collection box 13, the airflow velocity of the dust-laden air decreases, and the dust gradually settles and is collected under gravity. The purified air may be discharged through other ventilation channels of the collection box 13 or during subsequent cleaning and maintenance.

[0046] Inside the feed hopper 3, the second guide plate 16 guides the grain, allowing it to move more smoothly towards the bottom. The guide block 17 further assists the grain in converging into the first discharge pipe 18. The diversion grid plate 19 on the right side of the first discharge pipe 18 can perform preliminary diversion and sorting of the grain about to flow out.

[0047] The motor 25 starts the rotation, and its output drives the rotating rod 26 to rotate. The first gear 27, fixed at both ends of the rotating rod 26, rotates synchronously. Since the first gear 27 meshes with the rack 30, and the second gear 29 also meshes with the rack 30 and is rotatably connected inside the outer casing 20 through the connecting rod 28, when the first gear 27 rotates, the rack 30 begins to move linearly due to the interaction between the gear and the rack. The connecting ring 31 fixed to the outside of the rack 30 also moves with the rack 30. A conveying bucket 32 ​​is provided inside the connecting ring 31. The conveying bucket 32 ​​is fixed to the connecting ring 31 by the first connecting block 33 and bolts 34, thereby achieving a stable connection between the conveying bucket 32 ​​and the connecting ring 31.

[0048] As the connecting ring 31 moves, the conveying hopper 32 begins to move cyclically along a set trajectory. At the bottom of the outer shell 20, when the conveying hopper 32 passes the feeding area, which corresponds to the discharge position of the feeding hopper 3, grain falls from the feeding hopper 3 into the conveying hopper 32 through the first discharge pipe 18. The conveying hopper 32, filled with grain, moves upward along the interior of the outer shell 20 under the drive of the connecting ring 31. When it moves to the top near the top box 23, due to the change in the direction of movement of the conveying hopper 32 or its own tilting design, the grain is poured from the conveying hopper 32 into the top box 23, and then flows out through the second discharge pipe 24 at the bottom of the right side wall of the top box 23, and is transported to subsequent processing, storage and other stages.

[0049] In its normal placement state, the pulley 37 is positioned at a relatively high level inside the base 35. At this time, the grain elevator relies on the anti-slip pads 36 at the bottom of the four bases 35 to maintain stable contact with the ground. The anti-slip pads 36 increase friction with the ground, preventing accidental slippage during operation and ensuring the safety and stability of the equipment.

[0050] When the grain elevator needs to be moved, the electric push rod 39 is activated. The telescopic end of the electric push rod 39 begins to extend downwards. Because a second connecting block 41 is fixedly connected to the outer side of the telescopic end of the electric push rod 39, and second sliders 42 are fixedly connected to the left and right sides of the second connecting block 41, and the second sliders 42 are slidably connected in the front and rear slots of the second guide plate 40, it is ensured that the telescopic end of the electric push rod 39 maintains a straight line during its up-and-down movement, without deviation or wobbling, thus guaranteeing the smoothness and accuracy of the movement.

[0051] As the telescopic end of the electric push rod 39 moves downward, the connecting block 43 fixedly connected to its bottom drives the pulley 37 to move downward. When the pulley 37 descends to contact the ground and slightly raises the base 35, causing the anti-slip pad 36 to detach from the ground, the weight of the grain elevator is borne by the pulley 37. Through the rolling action of the pulley 37, the operator can easily push the grain elevator to move on the ground, realizing convenient transfer of the equipment.

[0052] Furthermore, once the grain elevator has moved to the designated position, the electric push rod 39 is activated again, causing its telescopic end to retract upwards. Driven by the electric push rod 39, the pulley 37 rises, and the base 35 re-establishes contact with the ground via the anti-slip pad 36, remaining stable and providing a stable support foundation for the normal operation of the grain elevator.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
