The scraper can float and adhere to the surface of the conveyor belt, and can elastically avoid hard grains or joints.

Description

Technical Field

[0001] This invention relates to the field of intelligent transportation equipment for agricultural products, and in particular to a side-mounted cleaner for corrugated sidewall conveyor belts. Background Technology

[0002] Corrugated sidewall conveyor belts are a special type of conveyor belt consisting of a base belt, retractable corrugated sidewalls on both sides, and a central cross diaphragm. They can continuously and tightly lift bulk grains at steep angles or even vertically, and are widely used for efficient bulk material transport in industries such as grain. During operation, the corrugated sidewalls and cross diaphragms on both sides of the base belt form a bucket-shaped space for lifting grains. However, during the return trip, a small amount of spilled or adhered grains can easily accumulate at the edge of the sidewall protection. If not removed in time, these grains will be rolled into the base belt and will rapidly wear down the rubber coating of the base belt like abrasives. Therefore, a cleaner is needed to continuously scrape off the remaining material to protect the belt and ensure the stable operation of the conveyor line.

[0003] Currently, the following problems still exist when using empty side cleaners on corrugated sidewall conveyor belts: Most existing cleaning devices are fixed installations. When the corrugated sidewall conveyor belt deviates from its course, the relative position between the cleaning scraper and the empty side of the conveyor belt changes, making it difficult for the empty side cleaner to maintain a stable contact pressure. Long-term operation can easily lead to local overpressure that aggravates wear or insufficient pressure that leaves material behind. It can also cause problems such as scraper edge biting and damage to the conveyor belt. Furthermore, the crest and trough structure of the corrugated sidewall makes it impossible for ordinary side scrapers to make contact. They either scrape hard and damage the sidewall or only touch the crest and miss the trough, causing material to accumulate in the trough for a long time. The accumulated grains will cause abnormal wear of the skirt due to repeated squeezing and friction during movement. Summary of the Invention

[0004] In view of the problems that still exist in the above or existing technologies when using empty side cleaners for corrugated sidewall conveyor belts, such as the fixed installation of the cleaning device and the difficulty in cleaning the corrugated sidewalls, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides a corrugated sidewall conveyor belt empty side cleaner, which is achieved by the following specific technical means: A corrugated sidewall conveyor belt empty side cleaner includes a corrugated sidewall conveyor and a discharge port disposed above it, wherein the corrugated sidewall conveyor is provided with a support rod located in front of the discharge port. A floating cleaning mechanism is mounted on a support rod. The floating cleaning mechanism includes a movable square tube that is horizontally slidably mounted on the support rod. Several first connecting rods are elastically mounted on the movable square tube. A scraper is hinged to the lower end of the first connecting rod through a torsion spring. A counterweight bin is fixedly mounted on the side of the scraper away from the corrugated sidewall conveyor. A second connecting rod that is elastically mounted on the movable square tube is symmetrically mounted on both sides. Several fan-shaped side scrapers are elastically mounted in an array on the side of the second connecting rod that is close to the corrugated sidewall of the corrugated sidewall conveyor. A deviation follow-up mechanism is installed on a corrugated sidewall conveyor; the deviation follow-up mechanism includes a C-shaped clamping frame installed on the corrugated sidewall conveyor, with pressure rollers close together at the top and bottom inside the C-shaped clamping frame, and a U-shaped support is installed between the C-shaped clamping frame and the moving square tube. The scraper scrapes against and avoids the horizontal surface of the corrugated sidewall conveyor. When the scraper returns to its original position, the counterweight bin makes it strike the corrugated sidewall conveyor. The fan-shaped side scraper avoids the corrugated sidewall of the conveyor and scrapes the material at the trough. When the corrugated sidewall conveyor deviates, the C-shaped clamp and U-shaped support work together to move the floating cleaning mechanism.

[0006] Preferably, the corrugated sidewall conveyor includes two symmetrical side plates, a plurality of drive rollers are rotatably mounted between the two side plates, and a corrugated sidewall belt is rotatably mounted between the plurality of drive rollers.

[0007] Preferably, an mounting plate is fixedly installed on the side plate, and a rotating sleeve is rotatably installed on the side of the mounting plate that is far apart from each other. The support rod slides through the rotating sleeves on both sides, and a first bolt is threaded onto the outer ring wall of the rotating sleeve. A positioning rod is fixedly installed on the mounting plate, and a return spring is fixedly installed between the positioning rod and the corresponding rotating sleeve.

[0008] Preferably, a fixed square tube is fixedly installed on the support rod, a movable square tube is slidably sleeved on the fixed square tube, a second bolt for adjusting the smoothness of sliding is threaded onto the movable square tube, and a limit strip is fixedly installed at the lower end of the movable square tube.

[0009] Preferably, a first slider corresponding to a first connecting rod is fixedly installed on the limiting strip, the first slider is hinged to the corresponding first connecting rod, and a first spring is hinged between the first slider and the corresponding first connecting rod.

[0010] Preferably, a second slider corresponding to a second connecting rod is fixedly installed on the limiting strip. The second slider is hinged to the corresponding second connecting rod. A second spring is hinged between the second slider and the corresponding second connecting rod. A first roller is rotatably installed on the end of the second connecting rod away from the corresponding second slider. A side support plate is fixedly installed on the side wall of the second connecting rod away from each other.

[0011] Preferably, a third spring corresponding to the fan-shaped side scraper is fixedly installed on the side support plate, and a limiting slide corresponding to the third spring is also fixedly installed on the side support plate. A third slider that is slidably connected to the corresponding limiting slide is fixedly installed on the telescopic end of the third spring. The fan-shaped side scraper is hinged to the corresponding third slider by a torsion spring. A second roller is rotatably installed on the third slider.

[0012] Preferably, the counterweight chamber has an injection port, and the scraper is covered with a wear-resistant coating.

[0013] Preferably, each of the side plates is fixedly installed with symmetrical upper and lower fixing plates on the side that is close to each other. The fixing plates are fixedly installed with a C-shaped clamping frame by a set spring rod. The horizontal section of the C-shaped clamping frame is threaded with a third bolt that is symmetrically arranged vertically and horizontally. A roller bracket located inside the C-shaped clamping frame is rotatably installed on the third bolt. A pressure roller is rotatably installed inside the roller bracket. The empty side part of the corrugated side guard belt is located between the horizontal sections of the C-shaped clamping frame.

[0014] Preferably, a triangular bracket is fixedly installed on the U-shaped bracket, and the triangular bracket and the movable square tube are rotatably connected by a bearing. The upper and lower corresponding U-shaped clamps are fixedly installed together with the U-shaped bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the scraper can float and fit against the conveyor belt base surface, and can elastically avoid hardened grains or joints, protecting the scraper and belt surface. During the return stroke, the scraper generates knocking vibration under the combined action of the torsion spring and the counterweight bin, effectively shaking off the adhering grains and preventing material accumulation to achieve self-cleaning. The fan-shaped side scraper floats elastically and can automatically avoid the undulations of the corrugated side guards, scraping only the trough area. This can thoroughly remove the residual material in the trough and avoid scratching or pulling the side guard crests, extending the service life of the side guards. The edge of the conveyor belt is clamped by the pressure roller. When the conveyor belt deviates, the U-shaped bracket drives the moving square tube to slide horizontally along the support rod, so that the cleaning mechanism follows the belt edge deviation in real time, always keeping the relative position of the scraper and the belt surface, and the side scraper and the side guard accurate, avoiding cleaning blind spots, edge biting, or side guard damage caused by deviation.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 A corrugated sidewall conveyor belt empty edge cleaner includes a corrugated sidewall conveyor 1 and a discharge port 2 disposed above it. A support rod 3 is disposed on the corrugated sidewall conveyor 1 in front of the discharge port 2.

[0030] A floating cleaning mechanism 4 is mounted on a support rod 3. The floating cleaning mechanism 4 includes a movable square tube 41 that is horizontally slidably mounted on the support rod 3. Several first connecting rods 42 are elastically mounted on the movable square tube 41. A scraper 43 is hinged to the lower end of the first connecting rod 42 by a torsion spring. A counterweight 46 is fixedly mounted on the side of the scraper 43 away from the corrugated sidewall conveyor 1. A second connecting rod 44 that is symmetrically mounted on the left and right sides is elastically mounted on the movable square tube 41. Several fan-shaped side scrapers 45 are elastically mounted in an array on the side of the second connecting rod 44 that is close to the corrugated sidewall of the corrugated sidewall conveyor 1.

[0031] Please see Figure 1 , Figure 2 , Figure 5 and Figure 9 The deviation follow-up mechanism 5 is installed on the corrugated sidewall conveyor 1. The deviation follow-up mechanism 5 includes a C-shaped clamping frame 51 installed on the corrugated sidewall conveyor 1. The C-shaped clamping frame 51 has pressure rollers 511 that are close together at the top and bottom inside. A U-shaped bracket 52 is installed between the C-shaped clamping frame 51 and the movable square tube 41.

[0032] The scraper 43 applies a scraping and avoidance action to the horizontal surface of the corrugated sidewall conveyor 1. When the scraper 43 returns to its position, the counterweight 46 causes it to strike the corrugated sidewall conveyor 1. The fan-shaped side scraper 45 avoids the corrugated sidewall of the corrugated sidewall conveyor 1 at the crest and scrapes the material at the trough. When the corrugated sidewall conveyor 1 deviates, the U-shaped clamp 51 and the U-shaped bracket 52 work together to move the floating cleaning mechanism 4.

[0033] In actual operation, the position of the support rod 3 ensures that the cleaning mechanism can clean the conveyor belt before the grain is unloaded. The elastic setting of the first connecting rod 42 allows it to deflect or shift to a certain extent when subjected to external force, and return to its original position after the external force is removed. The torsion spring allows the scraper 43 to generate a certain pressure when it contacts the horizontal surface of the conveyor belt, and at the same time, it can avoid obstacles or uneven conveyor belt surfaces by moving upwards, thus avoiding damage to the conveyor belt.

[0034] The counterweight bin 46 is a hollow container that can be filled with weights to provide additional downward pressure. When the scraper 43 returns to its original position during the cleaning process, the weight of the counterweight bin 46 enables it to strike the conveyor belt, helping to shake off small particles adhering to the conveyor belt.

[0035] The second connecting rod 44, which is symmetrically arranged on the left and right, is elastically set on the movable square tube 41, so that the second connecting rod 44 can adapt to the lateral changes of the corrugated sidewall. The movable square tube 41 can also be elastically set with third connecting rods (not shown in the figure) located on both sides of the second connecting rod 44, and several fan-shaped side scrapers 45 are also elastically arranged in an array on the side of the third connecting rod near the corrugated sidewall of the corrugated sidewall conveyor 1. At this time, the fan-shaped side scrapers 45 located on both sides of the corrugated sidewall can independently avoid the crest and scrape the trough, ensuring effective removal of the accumulated material inside the corrugated sidewall and the empty side.

[0036] The opening of the U-shaped clamp 51 faces the empty edge of the conveyor belt and is used to clamp the edge of the conveyor belt. The pressure roller 511 is made of wear-resistant rubber and is rotatably installed inside the U-shaped clamp 51 via bearings. It slightly clamps the empty edge of the conveyor belt to sense changes in the lateral position of the conveyor belt. When the conveyor belt shifts laterally, the U-shaped clamp 51 moves under the clamping action of the pressure roller 511 and transmits this movement to the moving square tube 41 through the U-shaped bracket 52, thereby driving the entire floating cleaning mechanism 4 to move laterally synchronously.

[0037] Thus, the scraper 43 can scrape and avoid the horizontal surface of the corrugated sidewall conveyor 1. When the scraper 43 returns to its original position, the counterweight 46 makes it strike the corrugated sidewall conveyor 1. The fan-shaped side scraper 45 can effectively remove the accumulated material inside the corrugated sidewall and the empty side of the corrugated sidewall conveyor 1. When the corrugated sidewall conveyor 1 deviates, the U-shaped clamp 51 and the U-shaped bracket 52 cooperate to move the floating cleaning mechanism 4.

[0038] Through the coordination of the floating cleaning mechanism 4 and the deviation follow-up mechanism 5, the cleaner can always maintain a stable relative position with the conveyor belt, ensuring that the scraper 43 continuously adheres to and scrapes the horizontal plane, while the fan-shaped side scraper 45 can adapt to the peaks and troughs of the corrugated sidewalls to achieve thorough grain removal, thereby protecting the belt body, extending the service life of the conveyor belt, and ensuring the stable operation of the conveyor line.

[0039] Please see Figure 1 and Figure 3 The corrugated sidewall conveyor 1 includes two symmetrical side plates 11, a plurality of drive rollers 12 are rotatably mounted between the two side plates 11, and a corrugated sidewall belt 13 is rotatably mounted between the plurality of drive rollers 12.

[0040] Please see Figure 2 , Figure 5 and Figure 6A mounting plate 31 is fixedly installed on the side plate 11. A rotating sleeve 32 is rotatably installed on the side of the mounting plate 31 that is far apart from each other. The support rod 3 slides through the rotating sleeves 32 on both sides. A first bolt 33 is threadedly connected to the outer ring wall of the rotating sleeve 32. A positioning rod 34 is fixedly installed on the mounting plate 31. A return spring 35 is fixedly installed between the positioning rod 34 and the corresponding rotating sleeve 32.

[0041] In actual operation, the rotating sleeve 32 allows the support rod 3 to rotate at a certain angle, providing angle adjustment for the cleaning mechanism. After the support rod 3 is adjusted to the required position, the first bolt 33 is tightened to press the support rod 3, thereby locking the position of the support rod 3. When the floating cleaning mechanism 4 encounters an obstacle or is deflected by an external impact during the cleaning process, the return spring 35 can provide a reliable restoring force, causing the support rod 3 and the floating cleaning mechanism 4 to automatically return to the preset cleaning position. This avoids the cleaning blind spot or efficiency reduction caused by the floating cleaning mechanism 4 due to temporary avoidance, ensuring that the cleaner and the corrugated sidewall conveyor 1 always maintain a stable contact pressure, and extending the service life of the corrugated sidewall conveyor 1.

[0042] Please see Figure 2 , Figure 4 , Figure 5 and Figure 7 A fixed square tube 411 is fixedly installed on the support rod 3. The movable square tube 41 is slidably sleeved on the fixed square tube 411. A second bolt 412 for adjusting the smoothness of sliding is threaded on the movable square tube 41. A limit strip 413 is fixedly installed at the lower end of the movable square tube 41.

[0043] In actual operation, the fixed square tube 411 and the movable square tube 41 form a support structure that can move laterally, so that the floating cleaning mechanism 4 can make lateral displacement according to the actual deviation or position change of the corrugated sidewall conveyor 1, thereby ensuring that the cleaning component is always in the ideal cleaning position. The second bolt 412 finely adjusts the sliding friction of the movable square tube 41 on the fixed square tube 411, ensuring that the movable square tube 41 can maintain sufficient flexibility to respond to deviation, and maintain the necessary stability, avoiding shaking caused by being too loose or response delay caused by being too tight.

[0044] The limiting strip 413 provides a stable reference mounting surface for the cleaning components to be installed later, ensuring that the cleaning components can maintain their integrity during movement and preventing the cleaning parts from deflecting or falling off due to uneven force, thereby improving the reliability and cleaning accuracy of the floating cleaning mechanism 4 during dynamic operation.

[0045] Please see Figure 2 , Figure 4 and Figure 5A first slider 421 corresponding to the first connecting rod 42 is fixedly installed on the limiting strip 413. The first slider 421 is hinged to the corresponding first connecting rod 42, and a first spring 422 is hinged between the first slider 421 and the corresponding first connecting rod 42.

[0046] In actual operation, when the scraper 43 is cleaning the horizontal surface of the corrugated sidewall conveyor 1, if it encounters unevenness or vibration on the surface of the corrugated sidewall conveyor 1, the first spring 422 can allow the first connecting rod 42 and the scraper 43 to make slight position adjustments and buffering through its extension and contraction. This allows the scraper 43 to dynamically adapt to the undulations of the surface of the corrugated sidewall conveyor 1 and always maintain a stable contact pressure with the corrugated sidewall conveyor 1, avoiding cleaning omissions caused by local overpressure wear or insufficient pressure due to rigid contact.

[0047] Please see Figure 2 , Figure 5 and Figure 7 A second slider 441 corresponding to the second link 44 is fixedly installed on the limiting bar 413. The second slider 441 is hinged to the corresponding second link 44. A second spring 442 is hinged between the second slider 441 and the corresponding second link 44. A first roller 443 is rotatably installed on the end of the second link 44 away from the corresponding second slider 441. A side support plate 444 is fixedly installed on the side wall of the second link 44 that is away from each other.

[0048] In actual operation, the limiting strip 413 provides a sliding mounting reference for the second link 44, allowing the second link 44 to be finely adjusted according to the actual position of the corrugated side guard. When the second link 44 is squeezed by the crest of the side guard, the second spring 442 can provide a reverse elastic restoring force, ensuring that the fan-shaped side scraper 45 always maintains the contact pressure with the side guard surface, avoiding damage caused by hard contact. The rolling contact between the first roller 443 and the horizontal plane of the corrugated side guard belt 13 reduces the frictional resistance of the second link 44 during movement and plays a guiding role, allowing the second link 44 to smoothly cross the cross plate of the corrugated side guard belt 13, while guiding the fan-shaped side scraper 45 deep into the trough for cleaning, improving the thoroughness of cleaning and reducing wear on the conveyor belt, thereby ensuring the continuity and stability of the cleaning operation.

[0049] Please see Figure 2 , Figure 5 , Figure 7 and Figure 8A third spring 451 corresponding to the fan-shaped side scraper 45 is fixedly installed on the side support plate 444. A limiting slide 452 corresponding to the third spring 451 is also fixedly installed on the side support plate 444. A third slider 453 that is slidably connected to the corresponding limiting slide 452 is fixedly installed on the telescopic end of the third spring 451. The fan-shaped side scraper 45 is hinged to the corresponding third slider 453 by a torsion spring. A second roller 454 is rotatably installed on the third slider 453.

[0050] In actual operation, several fan-shaped side scrapers 45 are elastically provided on the side of the third link and the second link 44 that are close to each other. The third spring 451 provides a preload force perpendicular to the surface of the side guard, ensuring that the fan-shaped side scrapers 45 always tend to move towards the side guard. The cooperation between the limiting slide 452 and the third slider 453 restricts the horizontal displacement freedom of the scraper, ensuring that the scraper always maintains the correct cleaning posture during the follow-up process. The fan-shaped side scrapers 45 are hinged to the third slider 453 by torsion springs. The elastic restoring force of the torsion springs allows the scraper to make an avoidance action when it contacts the crest of the wave, and to quickly rebound and penetrate into the bottom of the trough to scrape the material when it enters the trough. The second roller 454 allows the entire cleaning assembly to roll smoothly along the contour of the side guard, reducing the frictional resistance between the scraper and the side guard, and avoiding damage to the side guard caused by excessive friction. This cleans both the inner and outer sides of the corrugated side guard of the corrugated side guard conveyor 1, significantly improving the thoroughness of the corrugated side guard cleaning and the protection effect on the conveyor belt.

[0051] Please see Figure 4 The counterweight chamber 46 has an injection port, and the scraper 43 is covered with a wear-resistant coating.

[0052] In actual operation, the injection port allows the operator to flexibly adjust the striking force and bonding pressure of the scraper 43 on the corrugated sidewall conveyor 1 according to the actual working conditions. The outer layer of the scraper 43 is covered with a wear-resistant coating to enhance the wear resistance of the scraper 43 and reduce maintenance costs and replacement frequency.

[0053] Please see Figure 2 , Figure 5 and Figure 9 On the side of the side plates 11 that are close to each other, there are fixed plates 512 that are symmetrically installed vertically. The fixed plates 512 are fixedly installed with a U-shaped clamping frame 51 by a spring rod. The horizontal section of the U-shaped clamping frame 51 is threaded with a third bolt 513 that is symmetrically installed vertically and distributed horizontally. The roller bracket 514 located inside the U-shaped clamping frame 51 is rotatably installed on the third bolt 513. The pressure roller 511 is rotatably installed inside the roller bracket 514. The empty side part of the corrugated side guard belt 13 is located between the horizontal sections of the U-shaped clamping frame 51.

[0054] During operation, the spring rod ensures that the C-shaped clamp 51 maintains a flexible and stable contact pressure on the corrugated sidewall belt 13 during the follow-up process, preventing the pressure roller 511 from mechanically wearing out due to excessive pressure or from losing contact due to insufficient pressure. At the same time, the third bolt 513 allows the contact tightness between the pressure roller 511 and the empty edge of the belt to be adjusted according to the actual working conditions. The rotating pressure roller 511 inside the roller bracket 514 reduces the frictional resistance between it and the empty edge of the belt, preventing damage to the belt edge due to excessive friction.

[0055] This allows the empty side portion of the corrugated sidewall belt 13 to be placed between the upper and lower horizontal sections of the U-shaped clamping frame 51. By utilizing the clamping action of the upper and lower pressure rollers 511, any lateral deviation of the corrugated sidewall belt 13 can be directly converted into its own horizontal movement by the U-shaped clamping frame 51. This ensures that the floating sweeping mechanism 4 always accurately follows the deviation trajectory of the corrugated sidewall belt 13, thereby avoiding problems such as blind spots in sweeping, scraper 43 edge biting, and conveyor belt damage caused by the deviation of the corrugated sidewall belt 13, and improving sweeping efficiency and the service life of the conveyor belt.

[0056] Please see Figure 5 A triangular bracket 53 is fixedly installed on the U-shaped bracket 52. The triangular bracket 53 and the movable square tube 41 are rotatably connected by a bearing. The upper and lower corresponding U-shaped clamps 51 are fixedly installed on the U-shaped bracket 52.

[0057] In actual operation, the corresponding U-shaped clamping frame 51 and U-shaped bracket 52 form a stable follow-up base, ensuring that the deviation follow-up mechanism 5 can move synchronously. The triangular bracket 53 is rotatably connected to the moving square tube 41, providing a support point for the moving square tube 41. Furthermore, through the rotational freedom of the bearing, the stress or jamming that may occur in the moving square tube 41 during the follow-up process is eliminated, so that the cleaning mechanism can maintain a stable posture during the follow-up process. This ensures that the scraper 43 and the fan-shaped side scraper 45 can always adhere to the empty edge and corrugated side of the conveyor belt with stable pressure.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
