Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a scraper conveyor for wheat processing. Background Technology

[0002] Flour refers to the powder made from wheat, usually the middle part of the wheat after the husk has been removed. It is mainly composed of starch, and also contains protein, fat, vitamins, and minerals. During flour processing, a scraper conveyor is used to transport the raw wheat. In the prior art, patent CN 116513714 B discloses a scraper conveyor material-carrying device and its usage method, including: a transmission body shell, a controller, an internal cleaning mechanism, a tail body shell, a feed hopper, a head body shell, a discharge hopper, an anti-blocking cleaning mechanism, a transmission sprocket, a scraper chain, a partition, an anti-blocking inspection door, an air pump, and a drive motor; the internal cleaning mechanism is located at the top opening of the transmission body shell; the anti-blocking cleaning mechanism is installed on the right side of the outer wall of the head body shell; the partition is located in the inner cavity of the transmission body shell; and the anti-blocking inspection door is hinged to the head body shell. At the right end opening of the inner cavity, the scraper conveyor's material conveying device and its usage method are proposed. This paper proposes a new scraper conveying device and method for wheat material conveying, which reduces equipment wear, improves the service life of the device, and avoids the material conveying process from bringing the residue left over from the previous conveying process into the current conveying. The feed hopper of this device is always in the open state, which causes the wheat in the feed hopper to fill the space at the left end of the scraper conveyor. This can easily lead to congestion and blockage during the wheat conveying process. Therefore, we propose a scraper conveyor for wheat processing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a scraper conveyor for wheat processing. This device uses a transmission element to make the feed inlet of the scraper conveyor open and close intermittently as the material plate passes through, so as to avoid the problem of wheat filling the left end of the scraper conveyor due to the feed inlet being open all the time, which would cause the wheat conveying to be easily blocked. At the same time, the device can automatically collide and vibrate the scraper at the discharge part, reducing the probability of wheat sticking to the scraper at the discharge part, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a scraper conveyor for wheat processing, including a conveyor, wherein a feed hopper is provided through the left end of the top wall of the conveyor, and a discharge shell is provided through the right end of the bottom wall of the conveyor, and further includes a feeding mechanism; Feeding mechanism: It includes a partition, a through groove, a sealing plate, and an adjusting component. The partition is located at the lower end of the inside of the feeding hopper, and a through groove is opened in the middle of the partition. The lower end of the inside of the feeding hopper is equipped with a sealing plate through the adjusting component. The sealing plate is installed in conjunction with the through groove. This device uses a transmission element to make the feed inlet of the scraper conveyor open and close intermittently as the material plate passes through, so as to avoid the problem of wheat filling the left end of the scraper conveyor due to the feed inlet being constantly open, which would cause the wheat conveying to be easily blocked. At the same time, the device can automatically collide and vibrate the scraper at the discharge part to reduce the probability of wheat adhering to the scraper at the discharge part.

[0005] Furthermore, it also includes a microcontroller, which is located outside the conveyor. The input terminal of the microcontroller is electrically connected to an external power source, and the output terminal of the microcontroller is electrically connected to the input terminal of the conveyor, which facilitates the control of electrical components within the device.

[0006] Furthermore, the adjustment assembly includes a circular seat, a telescopic column, and a spring. The circular seats are symmetrically arranged longitudinally on the lower left wall of the feed hopper and the left side of the sealing plate. A telescopic column and a spring are provided between two adjacent circular seats. The springs are movably connected to the outer ends of the adjacent telescopic columns, so that the sealing plate in the scraper conveyor for wheat processing can automatically reset after moving to the left.

[0007] Furthermore, the adjustment assembly also includes a U-shaped seat, a rotating shaft, a positioning plate, an arc-shaped telescopic rod, and a spring. The U-shaped seat is located on the top wall of the sealing plate. The positioning plate is rotatably connected to the inside of the U-shaped seat through the rotating shaft. The lower end of the positioning plate is installed in conjunction with the scraper in the conveyor. An arc-shaped telescopic rod and a spring are provided between the top wall of the sealing plate and the left side of the positioning plate. The spring is movably sleeved with the outer end of the arc-shaped telescopic rod. The center of the arc of both the fixed end and the telescopic end of the arc-shaped telescopic rod coincides with the axis of the rotating shaft, so that the positioning plate in the scraper conveyor for wheat processing can automatically reset after rotating around the center of the rotating shaft.

[0008] Furthermore, the feeding mechanism also includes a limiting seat and a limiting rod. The limiting seat is disposed on the top wall of the sealing plate and is installed in conjunction with the positioning plate. A limiting rod is provided on the lower left wall of the feeding hopper and is installed in conjunction with the sealing plate to limit the movement of the sealing plate and the positioning plate in the scraper conveyor for wheat processing.

[0009] Furthermore, the interior of the feeding shell is rotatably connected by a rotating shaft two to two longitudinally symmetrically distributed annular seats. The outer side of the annular seats is provided with evenly distributed circular seats two. The middle of each circular seat two is provided with a diagonal rod through a telescopic column two and a spring two. The spring two is movably sleeved with the outer end of the adjacent telescopic column two. The diagonal rod is installed in conjunction with the scraper inside the conveyor. A servo motor is provided on the front side of the feeding shell. The input end of the servo motor is electrically connected to the output end of the microcontroller. The output shaft of the servo motor is fixedly connected to the front end of the rotating shaft two to collide and vibrate the scraper at the discharge part, reducing the probability of wheat adhering to the scraper at the discharge part.

[0010] Furthermore, a baffle is provided at the lower front end of the feed hopper to facilitate the replacement of springs and other components inside the feed hopper of the scraper conveyor for wheat processing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This scraper conveyor for wheat processing has the following advantages: 1. When using a scraper conveyor for wheat processing, the elastic elements and limiting elements work together, with the movement of the scraper inside the scraper conveyor as the main driving force. This causes the feed inlet of the scraper conveyor to open and close intermittently as the material plate passes through, avoiding the problem of wheat filling the left end of the scraper conveyor due to the feed inlet being constantly open, which would cause the wheat conveying to be easily blocked.

[0012] 2. When using a scraper conveyor for wheat processing, the device can automatically and intermittently collide with the scraper at the discharge section, causing the scraper at the discharge section to vibrate slightly. This vibration reduces the probability of wheat adhering to the scraper at the discharge section. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5This embodiment provides a technical solution: a scraper conveyor for wheat processing, including a conveyor 1. A feed hopper 3 is provided through the left end of the top wall of the conveyor 1, and a discharge shell 4 is provided through the right end of the bottom wall of the conveyor 1. It also includes a microcontroller 2, located outside the conveyor 1. The input end of the microcontroller 2 is electrically connected to an external power source, and the output end of the microcontroller 2 is electrically connected to the input end of the conveyor 1. Inside the discharge shell 4, two longitudinally symmetrically distributed annular seats 7 are rotatably connected via a rotating shaft 6. Circular seats 8 are evenly distributed around the outer side of the annular seats 7. Each circular seat 8 has a diagonal rod 11 in the middle via a telescopic column 9 and a spring 10. The spring 10 is movably sleeved with the outer end of the adjacent telescopic column 9. The diagonal rod 11 cooperates with the scraper inside the conveyor 1. The device is installed with a servo motor 12 on the front side of the discharge shell 4. The input end of the servo motor 12 is electrically connected to the output end of the microcontroller 2. The output shaft of the servo motor 12 is fixedly connected to the front end of the rotating shaft 6. When the device is used to transport wheat in the process of wheat flour preparation, the microcontroller 2 starts the conveyor 1. The conveyor 1 is a scraper conveyor, which consists of three parts: the head section, the middle section, and the tail section. Its core structure includes a drive unit (motor and reducer), a scraper chain, a chute, and a tensioning device. The head section includes a drive unit (motor + reducer), a sprocket assembly, and a head frame, which is responsible for providing power and pulling the chain. The middle section consists of a scraper chain, a chute, and a coal retaining plate, which undertakes the main function of material transportation. Tail section: Includes tail frame and tensioning device, used to adjust chain tension and support structure. During the operation of scraper conveyor, scraper chain, driven by drive device, makes closed-loop motion around sprocket. Wheat is pushed from left to right along the bottom channel of the device by scraper contact with the bottom surface of chute. When the chain is running in cycle, wheat is continuously conveyed to the unloading shell 4 for unloading. During the rightward movement of scraper on the lower side of conveyor 1, wheat is moved synchronously to the right. The scraper drives wheat to fall vertically downward through unloading shell 4. At the same time, microcontroller 2 starts servo motor 12, causing its output shaft to drive rotating shaft 6 to rotate in the opposite direction. Rotating shaft 6 drives the corresponding inclined rod 11 to rotate synchronously in the opposite direction through ring seat 7, round seat 8, telescopic column 9, and spring 10. During the reverse rotation of inclined rod 11, when its inclined rod is tilted... When the inclined rod 11 collides with the scraper at the discharge shell 4 of the conveyor 1, it moves towards the end closer to the axis of the rotating shaft 6 under pressure. The telescopic end of the telescopic column 9 and the spring 10 retract, thus rotating to avoid collision. After the inclined rod 11 separates from the scraper, it automatically moves away from the axis of the rotating shaft 6 due to the compression force of the spring 10. The rotating shaft 6 reverses direction, causing the inclined rod 11 to continuously collide with the scraper. This collision increases the vibration force of the scraper, and the vibration causes the wheat adhering to the scraper to fall into the discharge shell 4 automatically, reducing the probability of material adhering to the scraper during unloading. This device can automatically collide and vibrate the scraper at the discharge point, reducing the probability of wheat adhering to the scraper at the discharge point.It also includes the feeding mechanism 5; Feeding mechanism 5: It includes a partition plate 51, a through groove 52, a sealing plate 53, and an adjusting assembly 54. The partition plate 51 is located at the lower end of the inside of the feeding hopper 3. The through groove 52 is opened in the middle of the partition plate 51. The sealing plate 53 is located at the lower end of the inside of the feeding hopper 3 through the adjusting assembly 54. The sealing plate 53 is installed in conjunction with the through groove 52. The adjusting assembly 54 includes a circular seat 541, a telescopic column 542, and a spring 543. The circular seats 541 are symmetrically arranged longitudinally on the lower left wall of the feeding hopper 3 and the left side of the sealing plate 53. A telescopic column 542 and a spring 543 are provided between two adjacent circular seats 541. The springs 543 are movably sleeved with the outer end of the adjacent telescopic column 542. The adjusting assembly 54 also includes a U-shaped seat 544, a rotating shaft 545, and a fixed... Positioning plate 546, arc-shaped telescopic rod 547, and spring 548; U-shaped seat 544 is set on the top wall of sealing plate 53; positioning plate 546 is rotatably connected to the inside of U-shaped seat 544 via rotating shaft 545; the lower end of positioning plate 546 is installed in conjunction with scraper in conveyor 1; arc-shaped telescopic rod 547 and spring 548 are provided between the top wall of sealing plate 53 and the left side of positioning plate 546; spring 548 is movably sleeved with the outer end of arc-shaped telescopic rod 547; the arc center of both the fixed end and the telescopic end of arc-shaped telescopic rod 547 coincides with the axis of rotating shaft 545; feeding mechanism 5 also includes limiting seat 55 and limiting rod 56; limiting seat 55 is set on the top wall of sealing plate 53; limiting seat 55 is installed in conjunction with positioning plate 546; the lower left wall of feeding hopper 3 is provided with Limiting rod 56 is installed in conjunction with sealing plate 53. Baffle 13 is provided at the lower front end of feed hopper 3. During the wheat flour conveying process, wheat enters the bottom left end of conveyor 1 through feed hopper 3. The scrapers inside conveyor 1 are generally elliptical in shape. When the upper scraper inside conveyor 1 moves to the left and passes feed hopper 3, the upper end of the scraper is pressed against the lower end of positioning plate 546. In the initial stage, spring 3 548 and spring 1 543 are both in a contracted state. The horizontal component of the squeezing force exerted by spring 3 548 on positioning plate 546 is greater than the horizontal rightward squeezing force exerted by the two springs 1 543 on sealing plate 53. Therefore, when positioning plate 546 is subjected to the leftward squeezing force of the scraper, it does not rotate in the positive direction around the axis of rotating shaft 1 545. As the rotation continues, the positioning plate 546 indirectly drives the sealing plate 53 to move horizontally to the left, overcoming the compressive force of the spring 543. The telescopic end of the telescopic column 542 and the spring 543 retract. During the leftward movement, the sealing plate 53 gradually moves away from below the through groove 52, thereby releasing the blockage and limiting of the through groove 52. The wheat in the feed hopper 3 is fed along the through groove 52. When the positioning plate 546 moves a certain distance to the left with the scraper, the left side of the sealing plate 53 contacts the right end of the limiting rod 56. At this time, the sealing plate 53 no longer moves to the left. As the scraper continues to apply leftward pressing force to the lower end of the positioning plate 546, the positioning plate 546 overcomes the compressive force of the spring 548 and rotates in the positive direction around the axis of the rotating shaft 545. The telescopic end of the arc-shaped telescopic rod 547 and the spring 548 retract.The positioning plate 546 rotates forward around the axis of rotation 545, thereby continuously raising its lower end and separating it vertically from the scraper. After the positioning plate 546 is vertically separated from the scraper, the compression and reset force of the spring 543 causes the sealing plate 53 to automatically move to the right and block the through groove 52. The compression and reset force of the spring 548 causes the positioning plate 546 to rotate and reset around the axis of rotation 545, thus preparing for the scraper in the feeder 1 to pass by and discharge the material. The limit seat 55 limits the maximum reset critical point of the positioning plate 546 rotating and reset around the axis of rotation 545, so that the positioning plate 546 is always in a vertical state after reset. After the device has been used for a period of time, the circular seat 8 and its connecting elements are replaced as a whole (the circular seat 8 is installed on the corresponding annular seat 7 by screw 1), and the stop is removed. Plate 13 (baffle 13 is fixed to the feed hopper 3 with bolts). Through the exposed opening after removing baffle 13, replace the two horizontally adjacent circular seats 541 and the components between them as a whole (circular seats 541 are all fixed to the corresponding installation positions with screws). The upper and lower ends of the arc-shaped telescopic rod 547 and spring 548 are fixed to the corresponding installation positions with screws using circular seats 3. Replace the entire circular seat 3 along with the arc-shaped telescopic rod 547 and spring 548. Replace spring 543, spring 10, and spring 548 regularly to avoid spring aging. This device, through a transmission element, causes the feed inlet of the scraper conveyor to open and close intermittently as the material plate passes through, avoiding the problem of wheat filling the left end of the scraper conveyor due to a constantly open feed inlet, thus preventing easy blockage of wheat conveying.

[0017] The working principle of the scraper conveyor for wheat processing provided by this utility model is as follows: When the device is used to convey wheat in the process of making flour, the single-chip microcomputer 2 starts the conveyor 1. The conveyor 1 is a scraper conveyor, which consists of three parts: head, middle and tail. Its core structure includes a drive unit (motor and reducer), scraper chain, chute and tensioning device, etc. Head: includes drive unit (motor + reducer), sprocket assembly and head frame, responsible for providing power and pulling the chain. Middle: consists of scraper chain, chute and coal retaining plate, undertaking the main function of material transportation. Tail: includes tail frame and tensioning device, used to adjust the chain tension and support the structure. During operation, the scraper chain, driven by the drive device, makes a closed-loop motion around the sprocket. The scraper contacts the bottom of the chute, pushing the wheat along the bottom channel of the device from left to right. As the chain circulates, the wheat is continuously conveyed to the unloading hopper 4 for unloading. During the wheat flour production process, the wheat enters the bottom left end of the conveyor 1 through the feed hopper 3. The scrapers inside the conveyor 1 are generally elliptical in shape. When the upper scraper inside the conveyor 1 moves left past the feed hopper 3, the upper end of the scraper makes contact with the lower end of the positioning plate 546. Initially, both spring 3 548 and spring 1 543 are in a contracted state, and the horizontal component of the pressure exerted by spring 3 548 on the positioning plate 546 is greater than the water pressure exerted by the two springs 1 543 on the sealing plate 53. The positioning plate 546 is subjected to a leftward squeezing force from the scraper, so it does not rotate in the positive direction around the axis of the rotating shaft 545. At this time, the positioning plate 546 indirectly drives the sealing plate 53 to move horizontally to the left against the compressive force of the spring 543. The telescopic end of the telescopic column 542 and the spring 543 retract. During the leftward movement, the sealing plate 53 gradually moves away from below the through groove 52, thereby releasing the blockage and limiting of the through groove 52. The wheat in the feed hopper 3 is fed along the through groove 52. When the positioning plate 546 moves a certain distance to the left with the scraper, the left side of the sealing plate 53 contacts the right end of the limiting rod 56. At this time, the sealing plate 53 no longer moves to the left. As the scraper continues to apply leftward squeezing force to the lower end of the positioning plate 546, the positioning plate 546 overcomes the spring 548. The compression spring force causes the positioning plate 546 to rotate forward around the axis of the rotating shaft 545. The telescopic end of the arc-shaped telescopic rod 547 and the spring 548 retract. The positioning plate 546 rotates forward around the axis of the rotating shaft 545, thereby continuously raising its lower end position and separating it vertically from the scraper. After the positioning plate 546 is vertically separated from the scraper, the compression and reset spring force of the spring 543 causes the sealing plate 53 to automatically move to the right and block the through groove 52. The compression and reset spring force of the spring 548 causes the positioning plate 546 to flip and reset around the axis of the rotating shaft 545 in the reverse direction, thus preparing for the scraper in the feeder 1 to pass by and discharge the material. The limit seat 55 limits the maximum reset critical point of the positioning plate 546 flipping around the axis of the rotating shaft 545 in the reverse direction.This ensures that the positioning plate 546 remains vertical after reset. During the rightward movement of the scraper on the lower side of the conveyor 1, the wheat moves synchronously to the right. The scraper carries the wheat vertically downward through the discharge shell 4. Simultaneously, the microcontroller 2 activates the servo motor 12, causing its output shaft to drive the rotating shaft 6 in the reverse direction. The rotating shaft 6, through the annular seat 7, round seat 8, telescopic column 9, and spring 10, drives the corresponding inclined rod 11 to rotate synchronously in the reverse direction. During the reverse rotation of the inclined rod 11, when its inclined body collides with the scraper at the discharge shell 4 of the conveyor 1, the inclined rod 11 is pressed and moves towards the end closer to the axis of the rotating shaft 6. The telescopic end of the telescopic column 9 and the spring 10 retract, thus achieving a rotational position avoidance. After the inclined rod 11 separates from the scraper, it automatically moves away from the axis of the rotating shaft 6 and resets due to the compression force of the spring 10. The rotating shaft 6 then reverses direction, causing the inclined rod 11 to continuously collide with the scraper. The scraper is vibrated by impact, increasing its shaking force. This vibration causes wheat adhering to the scraper to fall automatically into the discharge shell 4, reducing the probability of material adhering during scraper unloading. After the device has been used for a period of time, the circular seat 2 8 and its connecting components are replaced as a whole (the circular seat 2 8 is installed on the corresponding annular seat 7 by screw 1). At the same time, the baffle 13 is removed (the baffle 13 is fixed to the feed hopper 3 by bolts). Through the exposed opening after the baffle 13 is removed, the two horizontally adjacent circular seats 1 541 and the components between them are replaced as a whole (the circular seats 1 541 are all fixed to the corresponding installation positions by screw 2). The upper and lower ends of the arc-shaped telescopic rod 547 and the spring 3 548 are fixed to the corresponding installation positions by the circular seat 3 with screw 3. The entire circular seat 3, along with the arc-shaped telescopic rod 547 and the spring 3 548, is replaced to prevent the springs from aging.
