Description

Technical Field

[0001] The invention relates to the technical field of flour production, and in particular to a raw wheat conveying device and method for flour processing. Background Art

[0002] In the flour processing process, the transportation of raw wheat is a key link. Raw wheat needs to be transported from the storage bin or receiving device to the cleaning equipment or grinding equipment to complete the cleaning, grading and grinding processes. Traditional raw wheat conveying devices mainly include belt conveyors, bucket elevators and screw conveyors. For conveying with large height differences, bucket elevators are often used to transport raw wheat.

[0003] In the conveying process of the existing bucket elevator, when the bucket shovels the materials accumulated at the arc-shaped bottom of the tail bottom shell, it is difficult to control the amount of materials shoveled by the bucket each time and the amount of materials filled when passing through the feed port, which easily causes the material to be overloaded or underloaded. When the bucket is overloaded, the upward conveying will not only affect the conveying rate of the material, but may also cause the bucket to deform and fall off in severe cases. Therefore, the publication number CN117923068B discloses a bucket elevator, which includes a bucket assembly for lifting materials from the bottom to the top; a lifting chamber, in which a conveying cavity is opened for shielding when the bucket assembly conveys materials; a tail bottom shell, fixedly installed at the bottom of the lifting chamber, for storing a certain amount of materials; a tail feed port, fixedly installed on the side wall of the tail bottom shell, for inflow feeding; a feeding unit, arranged inside the tail bottom shell, when the bucket assembly conveys materials, limits the amount of materials entering the bucket assembly so that the materials entering the bucket assembly tend to be balanced.

[0004] The above-mentioned bucket elevator is provided with a feeding unit so that the pouring port of the feeding unit is deflected toward the opening of the hopper assembly, which is conducive to pouring the collected material into the interior of the hopper assembly. Through the setting of the pushing bucket, the pushing bucket pushes the material gathered inside the shielding silo into the interior of the hopper assembly, which is conducive to reducing the occurrence of material residue on the shielding silo, and by pushing the internal material of the shielding silo, the material is better collected in the interior of the hopper assembly.

[0005] However, when the above-mentioned bucket elevator and the existing bucket elevator are used, there will be a lot of dust after the raw wheat is harvested. After the raw wheat is poured into the upper hopper, the hopper will be filled with the raw wheat and transported upward. The dust in the raw wheat will spread in the bucket elevator and adhere to the inner wall of the bucket elevator, which will cause transportation jams and affect the transportation efficiency. At the same time, when unloading, the hopper will flip over and the raw wheat in the hopper will be discharged, which will bring up a lot of dust and pollute the working environment of the workshop.

[0006] Therefore, a novel raw wheat conveying device and method based on flour processing can be adopted to solve the shortcomings of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Reference Figure 1-Figure 3 , Figure 5 , a raw wheat conveying device for flour processing, comprising a feeding unit 1, a lifting unit 2 and a conveying unit 3; The feeding unit 1 includes a feeding hopper 8 and a vibrating screen. The feeding hopper 8 is used to transport the raw wheat into the lifting unit 2. The vibrating screen is used to vibrate and screen the raw wheat in the feeding hopper 8 to remove stones in the raw wheat.

[0026] First, the raw wheat is dried and poured into the upper hopper 8, and then the raw wheat in the upper hopper 8 is vibrated and screened by a vibrating screen in the upper hopper 8 to remove stones and other heavy particle impurities in the raw wheat.

[0027] The vibrating screen generates periodic vibrations through a vibrating motor or exciter, causing the material on the screen surface to move relative to the material under the action of vibration, thereby achieving material screening, grading or impurity removal. It is an existing equipment and its specific operation will not be elaborated in detail here.

[0028] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 3 , Figure 6-Figure 19 The lifting unit 2 is located at the upper part of the feeding unit 1, and the lifting unit 2 includes a frame 10, on which two adjustment shafts 9 are rotatably mounted; The adjusting shaft 9 is a rotating shaft whose position can be freely adjusted. It can be adjusted according to the tightness of the lifting track 7 to ensure that the lifting track 7 remains within a stable tension. Electric adjustment is adopted. A lifting track 7 tension sensor is installed on the frame 10. The tension sensor controls the position adjustment of the adjusting shaft 9.

[0029] A lifting crawler 7 is sleeved between the two adjusting shafts 9 , and a plurality of material transport components 4 are fixedly mounted on the lifting crawler 7 . The material transport component 4 is composed of a material transport hopper 15 , and the raw wheat in the upper hopper 8 is transported to the top of the lifting unit 2 through the material transport hopper 15 .

[0030] A sieve plate 17 is slidably installed inside the material transport hopper 15, and a vibration mechanism that cooperates with the sieve plate 17 is installed on the material transport hopper 15 and the frame 10; the sieve plate 17 adopts a one-way design, and the sieve holes opened on its upper part are of one-way design. Dust can only fall from the top of the sieve plate 17 to the bottom, but cannot fall in the opposite direction. This ensures that when the sieve plate 17 is rotated and flipped, the dust will not pass through the sieve plate 17 from the bottom of the material transport hopper 15 and fall into the frame 10. The dust will only remain on the sieve plate 17. Then a dust collection device is arranged inside the frame 10. When the material transport hopper 15 moves to the dust collection device, the dust collection device sucks out the dust on the sieve plate 17.

[0031] The vibration mechanism includes a support frame 35 fixedly installed inside the material transport hopper 15, the sieve plate 17 and the support frame 35 are slidably connected, a plurality of springs are fixedly installed between the sieve plate 17 and the support frame 35, a camshaft 21 matching the sieve plate 17 is rotatably installed on the material transport hopper 15, a gear cylinder 20 is fixedly installed on the camshaft 21, a plurality of tooth plates 11 matching the gear cylinder 20 are fixedly installed at equal intervals on the frame 10 (the tooth plates 11 are only arranged on the side where the material transport hopper 15 rises, and vibration is generated when the material transport hopper 15 rises, but no vibration is required when it falls), and a tumbling structure 16 matching the camshaft 21 is installed in the material transport hopper 15; The material transport hopper 15 moves upward along with the lifting crawler 7. During the process, the gear cylinder 20 will mesh with the gear plate 11. The gear plate 11 does not move, and the gear cylinder 20 moves upward, so the gear cylinder 20 will rotate under the action of the gear plate 11. The rotation of the gear cylinder 20 drives the camshaft 21 to rotate, thereby driving the screen plate 17 to vibrate up and down. The spring is in a pulled-up state, which is used to pull the screen plate 17 downward to reset; The tooth plates 11 are arranged intermittently with equal spacing, so that the vibration generated is intermittent vibration, which can redistribute the raw wheat on the screen plate 17 when the vibration stops, thereby preventing the raw wheat from piling up and clogging the screen plate 17; Intermittent vibration reduces the continuous mechanical stress on the equipment during operation and reduces fatigue damage to key components. At the same time, intermittent vibration makes the movement of the raw wheat on the screen plate 17 more uniform, reduces local wear of the screen plate 17, and extends the service life of the screen plate 17.

[0032] The tumbling structure 16 includes a rotating tube 37 rotatably mounted inside the material transport hopper 15, the rotating tube 37 is connected to the camshaft 21 via a transmission belt 22, a plurality of vibrating rubber rings 39 are fixedly mounted on the rotating tube 37, a tumbling rod 38 is fixedly mounted on each vibrating rubber ring 39, each tumbling rod 38 penetrates and extends into the interior of the rotating tube 37, a concave-convex shaft 36 is fixedly mounted on the inner wall of the material transport hopper 15, and a pressure wheel 40 matching the concave-convex shaft 36 is rotatably mounted on one end of each tumbling rod 38 located inside the rotating tube 37.

[0033] As the camshaft 21 rotates, the transmission belt 22 drives the rotating tube 37 to rotate, and the rotating tube 37 drives the tumbling rod 38 to make a circular motion around the central axis of the rotating tube 37, stirring the raw wheat in the hopper 15, and accelerating the separation of dust on the raw wheat from the raw wheat; At the same time, since the rotating tube 37 rotates and the concave-convex shaft 36 does not rotate, the pressure wheel 40 on the tumbling rod 38 will press against the concave-convex shaft 36. At this time, the vibrating rubber ring 39 not only seals the gap between the tumbling rod 38 and the rotating tube 37, but also provides a reset elastic force for the tumbling rod 38. The tumbling rod 38 will vibrate under the action of the concave-convex shaft 36 and the vibrating rubber ring 39, further accelerating the speed at which dust falls off the raw wheat and improving the cleaning efficiency.

[0034] A blocking mechanism matching the material transport hopper 15 is installed between the material transport hopper 15 and the frame 10, a tension spring in a compressed state is fixedly installed between the sliding frame 29 and the bottom of the storage slot, and a reset structure matching the sliding frame 29 is installed on the frame 10; The blocking mechanism includes a receiving groove provided on the side wall of the material transport hopper 15, in which a retractable third corrugated plate 28 is received, one end of the third corrugated plate 28 is fixedly connected to the bottom of the receiving groove, and a sliding frame 29 is fixedly installed on the end of the third corrugated plate 28 away from the bottom of the receiving groove, and a limiting structure 25 matched with the sliding frame 29 is installed on the material transport hopper 15 and the frame 10; refer to Figure 6When the material transport hopper 15 rotates to the bottom of the lifting track 7, the material transport hopper 15 is horizontal at this time, and the raw wheat at the bottom of the frame 10 is loaded into the material transport hopper 15. As the lifting track 7 rotates, the material transport hopper 15 changes from horizontal to vertical. At this time, the material transport hopper 15 is filled with raw wheat. When the material transport hopper 15 enters the rising stage, the limiting structure 25 will be triggered to operate at the first time, so that the sliding frame 29 loses the limit of the limiting structure 25. At this time, under the action of the tension spring, the third corrugated plate 28 will pop out from the storage groove, so that the third corrugated plate 28 will block the material transport hopper 15, which can not only prevent the raw wheat from falling from the material transport hopper 15 due to the vibration generated by the mechanical operation, but also effectively prevent dust from flying.

[0035] The limiting structure 25 includes an elastic telescopic rod 32 fixedly mounted on the side wall of the material transport hopper 15. The elastic telescopic rod 32 is hollow in design. A plug 31 with a hemispherical end is fixedly mounted on the telescopic end of the elastic telescopic rod 32. A plug hole matching the plug 31 is provided on the sliding frame 29. A pull rod 33 is fixedly mounted on the plug 31. The pull rod 33 passes through the elastic telescopic rod 32. A second magnetic block 34 is fixedly mounted on the end of the pull rod 33 away from the plug 31. An iron plate 30 matching the second magnetic block 34 is fixedly mounted on the frame 10.

[0036] When the material transport hopper 15 just enters the vertical ascent stage, the gear cylinder 20 is not engaged with the gear plate 11. At this time, the second magnetic block 34 will approach the iron plate 30, and the second magnetic block 34 will absorb the iron plate 30, while the iron plate 30 does not move. Therefore, the second magnetic block 34 will move to the side close to the iron plate 30. The movement of the second magnetic block 34 drives the pull rod 33 to move, thereby driving the bolt 31 to move, so that the bolt 31 is separated from the slot. At this time, the sliding frame 29 loses the limit of the bolt 31, and will automatically pop out of the storage slot under the action of the tension spring.

[0037] As the hopper 15 continues to rise, the distance between the second magnetic block 34 and the iron plate 30 becomes larger and larger, and the plug 31 is reset under the action of the elastic telescopic rod 32. The end of the plug 31 is designed to be hemispherical, so that it is easy to be inserted into the slot. Only one iron plate 30 is provided; The elastic force of the elastic telescopic rod 32 is greater than the elastic force of the tension spring.

[0038] The reset structure includes a first magnetic block 23 fixedly mounted on a sliding frame 29, and a tilted magnetic plate 14 matched with the first magnetic block 23 is fixedly mounted on the frame 10. The upper part of the lifting unit 2 is a discharge port. After the hopper 15 is flipped, the raw wheat in the hopper 15 will be poured into the discharge port. The tilted magnetic plate 14 is located at the upper part of the discharge port. As the hopper 15 moves (at this time the hopper 15 is flipped over with the bottom facing up), the first magnetic block 23 will attract the tilted magnetic plate 14, and the tilted magnetic plate 14 will drive the first magnetic block 23 to move, thereby driving the sliding frame 29 to reset, so that the third corrugated plate 28 is retracted into the receiving groove.

[0039] The bottom of the material transport hopper 15 is designed to be open, and a sealing mechanism that cooperates with the material transport hopper 15 is installed between the material transport hopper 15 and the frame 10; The sealing mechanism includes a sliding groove opened on the material transport hopper 15, a sliding rod is slidably installed in the sliding groove, a first corrugated plate 18 matching the bottom opening of the material transport hopper 15 is fixedly installed between the sliding rod and the material transport hopper 15, an adjustable telescopic rod 24 is fixedly installed on the sliding rod, a magnetic disk 41 is rotatably installed on the adjustable telescopic rod 24, and a side V-shaped magnetic plate 13 that attracts the magnetic disk 41 is fixedly installed on the frame 10.

[0040] When the material transport hopper 15 is flipped over, as the lifting track 7 moves downward, when it moves close to the lower part (at this time the material transport hopper 15 is still in a vertical state, not in a horizontal or inclined state), the magnetic disk 41 on the material transport hopper 15 will be close to the side V-shaped magnetic plate 13, and the magnetic disk 41 will be attracted to the side V-shaped magnetic plate 13. The magnetic disk 41 will be adsorbed on the side V-shaped magnetic plate 13. As the material transport hopper 15 moves downward, the magnetic disk 41 will move along the side V-shaped magnetic plate 13, thereby driving the first corrugated plate 18 to move, thereby opening the lower end opening of the material transport hopper 15, and at this time the dust collection equipment will suck out the dust in the material transport hopper 15.

[0041] A scraping mechanism matched with the sieve plate 17 is installed between the material transport hopper 15 and the frame 10 .

[0042] The scraping mechanism includes two scrapers 27 slidably mounted inside the material transport hopper 15, each of which is fixedly mounted with a sliding rod 19, and two side V-shaped guide rails 12 matching the corresponding sliding rods 19 are fixedly mounted on the frame 10. A trough body for the two sliding rods 19 to move is provided on the side of the material transport hopper 15, and a second corrugated plate 26 matching the trough body is fixedly mounted between the two sliding rods 19 (the side V-shaped guide rails 12 are arranged in two places, one is in the vertical unloading section after the material transport hopper 15 is turned over, which is used for unloading to prevent raw wheat from sticking to the screen plate 17, and the other is located at the vertical bottom end of the flipped material transport hopper 15, which drives the scraper 27 to operate in order to further scrape the dust from the screen plate 17 and reduce the probability of blockage of the screen plate 17).

[0043] When the material transport hopper 15 is at the uppermost part (at this time, the material transport hopper 15 is turned over with the bottom facing upward, and the material transport hopper 15 is in a vertical state and is in the unloading section), when the material transport hopper 15 moves downward, it will drive the sliding rod 19 to move downward, and the sliding rod 19 will enter the side V-shaped guide rail 12. The sliding rod 19 will move along the side V-shaped guide rail 12, thereby driving the scraper 27 to move horizontally back and forth once, so as to scrape off the raw wheat adhering to the screen plate 17.

[0044] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1-Figure 4The conveying unit 3 is located on the upper part of the lifting unit 2. The conveying unit 3 includes a driving motor 5 fixedly mounted on a frame 10. The driving end of the driving motor 5 is connected to the adjusting shaft 9 located on the upper part through a reducer 6.

[0045] After screening, the raw wheat will automatically enter the lifting unit 2, and then the conveying unit 3 is started. The conveying unit 3 drives the adjusting shaft 9 connected to it to rotate, which will drive the lifting crawler 7 to rotate, thereby driving the material transport component 4 on the lifting crawler 7 to move, and the material transport hopper 15 in the material transport component 4 will transport the raw wheat at the bottom of the lifting unit 2 upward.

[0046] The function of the speed reducer 6 is to reduce the operating speed of the lifting unit 2 and reduce vibration.

[0047] The specific operation steps of this device are as follows: First, the raw wheat is dried and poured into the upper hopper 8, and then the raw wheat in the upper hopper 8 is vibrated and screened by the vibrating screen in the upper hopper 8 to remove stones and other heavy particle impurities in the raw wheat; After the screening, the raw wheat will automatically enter the lifting unit 2, and then the conveying unit 3 will be started. The conveying unit 3 drives the adjusting shaft 9 connected to it to rotate, which will drive the lifting crawler 7 to rotate, thereby driving the material transport component 4 on the lifting crawler 7 to move; When the material transport hopper 15 rotates to the bottom of the lifting crawler 7, the material transport hopper 15 is horizontal at this time, and the raw wheat at the bottom of the frame 10 is loaded into the material transport hopper 15. As the lifting crawler 7 rotates, the material transport hopper 15 will change from horizontal to vertical. At this time, the material transport hopper 15 is filled with raw wheat. When the material transport hopper 15 enters the rising stage; When the material transport hopper 15 just enters the vertical ascending stage, the gear cylinder 20 is not meshed with the gear plate 11. At this time, the second magnetic block 34 will approach the iron plate 30, and the second magnetic block 34 will attract the iron plate 30, while the iron plate 30 does not move. Therefore, the second magnetic block 34 will move to the side close to the iron plate 30. The movement of the second magnetic block 34 drives the pull rod 33 to move, thereby driving the plug 31 to move, so that the plug 31 is separated from the slot. At this time, the sliding frame 29 loses the limit of the plug 31, and automatically pops out of the storage slot under the action of the tension spring, and the third corrugated plate 28 pops out from the storage slot, so that the third corrugated plate 28 blocks the material transport hopper 15. As the material transport hopper 15 moves upward along with the lifting crawler 7, during the process, the gear cylinder 20 will mesh with the tooth plate 11, the tooth plate 11 does not move, and the gear cylinder 20 moves upward, so the gear cylinder 20 will rotate under the action of the tooth plate 11, and the rotation of the gear cylinder 20 drives the camshaft 21 to rotate, thereby driving the screen plate 17 to vibrate up and down; as the camshaft 21 rotates, it will drive the rotating tube 37 to rotate through the transmission belt 22, and the rotation of the rotating tube 37 will drive the tumbling rod 38 to make a circular motion around the central axis of the rotating tube 37, so as to vibrate the hair inside the material transport hopper 15 The wheat is stirred to accelerate the separation of dust on the wheat; at the same time, since the rotating tube 37 rotates and the concave-convex shaft 36 does not rotate, the pressing wheel 40 on the tumbling rod 38 will press against the concave-convex shaft 36. At this time, the vibrating rubber ring 39 not only seals the gap between the tumbling rod 38 and the rotating tube 37, but also provides a restoring elastic force for the tumbling rod 38. The tumbling rod 38 will vibrate under the action of the concave-convex shaft 36 and the vibrating rubber ring 39, further accelerating the speed at which dust on the wheat falls off; When the transport hopper 15 is at the uppermost part (at this time, the transport hopper 15 is turned over, the bottom is facing upward, and the transport hopper 15 is in a vertical state and is in the unloading section), the transport hopper 15 will pour the raw wheat in the transport hopper 15 into the unloading port after turning over, and the inclined magnetic plate 14 is located at the upper part of the unloading port. As the transport hopper 15 moves (at this time, the transport hopper 15 is turned over, the bottom is facing upward), the first magnetic block 23 will be attracted to the inclined magnetic plate 14, and the inclined magnetic plate 14 will drive the first magnetic block 2 3 moves, thereby driving the sliding frame 29 to reset, so that the third corrugated plate 28 is retracted into the receiving groove, and the raw wheat in the hopper 15 will fall from the hopper 15 to the discharge port. At this time, when the hopper 15 moves downward, it will drive the sliding rod 19 to move downward, and the sliding rod 19 will enter the side V-shaped guide rail 12. The sliding rod 19 will move along the side V-shaped guide rail 12, thereby driving the scraper 27 to move horizontally back and forth once, which is used to scrape off the raw wheat adhering to the screen plate 17; When the material transport hopper 15 is flipped over, as the lifting track 7 moves downward, when it moves close to the lower part (at this time the material transport hopper 15 is still in a vertical state, not in a horizontal or inclined state), the magnetic disk 41 on the material transport hopper 15 will be close to the side V-shaped magnetic plate 13, and the magnetic disk 41 will be attracted to the side V-shaped magnetic plate 13. The magnetic disk 41 will be adsorbed on the side V-shaped magnetic plate 13. As the material transport hopper 15 moves downward, the magnetic disk 41 will move along the side V-shaped magnetic plate 13, thereby driving the first corrugated plate 18 to move, thereby opening the lower end opening of the material transport hopper 15, and at this time the dust collection equipment will suck out the dust in the material transport hopper 15.
