Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to an anti-slip belt conveyor. Background Art

[0002] A belt conveyor is a conveying device used to transport materials. Its main structure includes a frame, belt, belt drum, drive mechanism, and rollers. Depending on the material's transport method, a belt conveyor can transport materials horizontally or elevate them from a low position to a high position.

[0003] Belt conveyors are widely used in industry because of their high material transmission efficiency, high transmission stability, and ability to transmit materials horizontally over long distances and with high height differences.

[0004] When conveying materials on a belt conveyor, especially when conveying materials from a low place to a high place, the material may be unable to be lifted up further after being conveyed on the conveyor belt to a certain height, and may slip on the belt, causing subsequent materials to accumulate there. When the accumulation reaches a certain level, the material may slide down along the belt or outward from the edge of the belt.

[0005] The specific reasons include many factors, such as the material is too dry, too fluid, and the belt has been used for many years, the contact surface between the belt and the material is too worn, resulting in the belt being too smooth, the belt tensioning force is not enough, the material conveying height is too high, and there is dirt on the belt, etc.

[0006] For human-controllable factors such as insufficient belt tension, tensioning can be used to increase material transmission stability during actual production. However, for uncontrollable factors such as excessive belt wear, belt smoothness, excessive material fluidity (such as material with too small particle size), and excessive material transmission height, it is often difficult to fundamentally solve the problem during actual operation.

[0007] The disadvantage of replacing a new belt is that the replacement cost is too high. Once the material such as large particles is transmitted, although the wear increases, the material can still be transmitted smoothly. Therefore, the replacement belt method is obviously not feasible in the actual production process.

[0008] In order to solve the technical problem of belt material slipping and sliding, the existing technology has adopted methods such as increasing the cleanliness of the belt. For example, Chinese patent application number: CN202123293573.2 discloses a closed belt conveyor with an anti-dust structure. Through the fitting scraper fixedly installed at the end of the protective cover, the surface of the conveyor belt can be cleaned during the return journey, and the adhered material can be scraped off to avoid the material from running off and the material from sliding and accumulating.

[0009] The technical solution disclosed in the above patent improves the cleanliness of the belt by cleaning it with a scraper to prevent materials from sliding down and accumulating.

[0010] However, in actual operation, the fundamental reasons for material slippage are often due to the high fluidity of the material, the material being too light, and excessive belt wear resulting in a smooth surface and low friction with the material. Therefore, even cleaning the belt will not fundamentally solve the problem of material slippage.

[0011] Therefore, in actual working process, operators often use tools such as rakes to push materials and reduce the feeding amount of the material feeding conveyor belt when materials slide up and down, slip, stagnate and accumulate on the conveyor belt.

[0012] However, in actual working process, due to the frequent sliding, slipping, stagnation and accumulation of materials during material transmission, it is difficult to monitor the material transmission situation for a long time and immediately rake the material transmission when the above conditions occur.

[0013] At the same time, since the above situation often occurs when the material is at a high position on the belt conveyor, emergency treatment is more difficult. Summary of the Invention

[0014] Based on the above background, an object of the present invention is to provide an anti-slip belt conveyor.

[0015] To achieve the above objectives, the present invention adopts the following technical solutions:

[0020] The anti-slip plate is equipped with a contouring arm mechanism. When the anti-slip plate pushes the slipping material upward, the contouring arm mechanism is used to gather the material on the conveyor belt to the center of the conveyor belt to prevent the material from slipping off the edge of the conveyor belt.

[0021] The contour arm mechanism includes a pair of contour arms that cooperate with each other. During the process of embracing the materials, the contour arms embracing the materials from a scattered state to a stacked state.

[0022] Preferably, the ends of the horizontal frame portion and the overhead frame portion are rotatably connected to belt rollers, and the transmission belt is driven between the belt rollers;

[0028] Preferably, a rail frame is fixedly connected to the inner side of the guide rail, and a rectangular sliding opening is opened on the rail frame, and the two ends of the roller shaft are respectively limited in the rectangular sliding opening; a guide rail rod is fixedly connected in the rectangular sliding opening, and the guide rail rod passes through the roller shaft.

[0029] Preferably, the steel cable structure comprises steel cables spaced apart on both sides, and the lower ends of the steel cables are respectively fixedly connected to the roller shafts;

[0030] The upper end of the steel cable is guided by the guide wheel structure, and the free end of the steel cable is wound on the reel structure.

[0036] Preferably, the contoured arm comprises an arm frame;

[0037] The top of the arm is fixedly connected to a holding arm corresponding to the shape of the arm;

[0038] The inner end of the arm is hinged on the anti-slip plate, and the anti-slip plate is hinged with an electric push rod structure for pushing and pulling the arm.

[0039] Preferably, the arm bracket includes an arc-shaped arm portion, and the inner end of the arc-shaped arm portion is hinged to a hinge seat on the anti-slip plate;

[0040] The outer end of the arc arm portion is integrally formed with a straight arm portion, and the straight arm portion is integrally formed with an arm-holding portion;

[0043] The pushing end of the electric push rod is fixedly connected with a push rod, and the push rod is hinged at the top position of the material holding arm.

[0044] Preferably, the side walls on both sides of the anti-slip plate are tilted inward to form a slope surface. When the anti-slip plate pushes the material upward, the slope surface prevents the two sides of the anti-slip plate from pushing the material toward the edge of the conveyor belt.

[0045] The present invention has the following beneficial effects:

[0046] 1. In the belt conveyor disclosed in the present invention, an anti-slip mechanism is installed at the upward conveying end of the belt conveyor to achieve a process in which, during operation, when material slips and slides down at the upward position of the transmission belt, as the subsequent conveyed material continues to accumulate, the material volume gradually increases and rises above the anti-slip plate. At this time, the anti-slip plate is pulled toward the discharge end of the frame by a traction assembly. The anti-slip plate tilts upward along the slope of the overhead frame to push the stagnant and slipping material upward and facilitate the discharge of the material. At this time, since the material accumulated at the slipping position is pushed away, the material can be normally transported upward under the transmission of the conveyor belt. Therefore, by timely pushing the accumulated and slipping material, the technical defect of serious downward sliding after a large amount of material is prevented from being retained is avoided.

[0047] Specifically, after pushing, the material at the accumulated and slipping position is reduced, and the conveyor belt is transported, and the material can be transported normally again. If accumulation, slipping, or sliding occurs again, continue to push.

[0048] 2. When the anti-slip plate assists in raising the material to a position close to the discharge end, the material is normally transported and dropped by the conveyor belt. At this time, the downward slope of the overhead frame is utilized. When the reel structure unwinds the steel cable structure, the anti-slip plate quickly descends to prepare for emergency handling of the above situation again.

[0049] When the reel structure winds up the steel cable structure, the anti-slip plate moves upwards, pushing the slipping and accumulated materials on the conveyor belt upwards; when the reel structure unwinds the steel cable structure, the anti-slip plate rolls down through the guide wheel structure by its own gravity, ready to push the material again.

[0050] 3. The anti-slip mechanism disclosed in the present invention essentially solves the problem of material accumulation and slipping during the process of belt conveyor lifting, and assists in pushing the accumulated, slipping, and sliding materials upward. After the push, the amount of material in the accumulation and slipping positions is greatly reduced. This not only prevents the material from seriously sliding down the slope of the conveyor belt after a large amount of material accumulation, but also prevents the material from sliding down the edge of the belt due to excessive accumulation. At the same time, it can ensure the continuous flow of logistics. If the material in the accumulation and slipping positions is not pushed away in time, the subsequent continuous flow of material will continue to accumulate there, affecting the smoothness of material transmission.

[0051] 4. A contoured arm mechanism is installed on the anti-slip plate. As the anti-slip plate pushes upward against slipping material, the contoured arm mechanism is used to gather material on the conveyor belt to the center of the conveyor belt, preventing it from slipping off the edge. Specifically, the contoured arm mechanism comprises a pair of cooperating contoured arms. During this process, the contoured arms gather the material from a scattered state to a piled state. This contoured arm mimics the way human arms gather material. As material approaches the edge of the belt, the contoured arms continuously gather the material from the edge toward the center, preventing it from falling off the edge of the conveyor belt.

[0052] 5. To prevent the continued accumulation of materials, which may lead to downward or sideways sliding, and subsequent accumulation of materials being continuously transmitted, during the operation of the belt conveyor, the steel cable is reeled by means of a motor-driven reel shaft. During the reeling process, the steel cable pulls the roller shaft upward, and correspondingly, the material on the anti-slip plate fixed on the roller shaft is pushed upward. In this process, the use of steel cable pulling is intended to, on the one hand, utilize the greater pulling force of the steel cable to push the accumulated materials upward at an angle, and on the other hand, to reduce the upward resistance of the roller shaft and anti-slip plate by using the roller rolling method. What is even better is that when the material is pushed to a certain height, the material can be transported normally by the conveyor belt. At this time, the anti-slip plate, roller shaft, and roller can be quickly unwound by the reel (the steel cable is wound in the wheel groove of the reel) to quickly slide down and roll to the initial position along the guide rail, rail frame, and guide rail rod, so as to quickly push the accumulated and slipping materials upward again.

[0053] The problem that if the anti-slip plate, roller shaft and roller cannot be quickly reset to the initial position, once a large amount of material slips, stays and accumulates before the anti-slip plate is reset, the anti-slip plate is blocked by the material and cannot be reset. Even if it is reset, the accumulated material will be pushed down is solved.

[0054] However, traditional pushing structures such as air cylinders, hydraulic cylinders, and push plates are unable to push a large amount of material upward and then reset it at a very fast speed.

[0055] 6. The anti-deformation arm design ensures that, when the electric push rod is pulled, the inner curved arm first pushes the material at the edge of the conveyor belt toward the center of the belt, where it accumulates close to each other. Then, with the cooperation of the straight arm, the material is further significantly gathered toward the center. Finally, the material is confined in a pile in the gap formed by the two curved arms.

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0072] Example 1

[0073] like Figure 1-11 As shown, an anti-slip belt conveyor includes a frame 1, the frame 1 includes a horizontal frame part 11 and an upward-facing frame part 12 (that is, the conveyor includes a total of two sections during the material conveying process, one end is used to convey the material horizontally, and the other end is used to lift and convey the material, until the material is lifted and conveyed from a low place to a high place), and a conveyor belt 2 for conveying materials is installed on the frame 1.

[0074] Specifically, similar to the existing belt conveyor structure, the ends of the horizontal frame portion 11 and the overhead frame portion 12 are rotatably connected to belt rollers, and the transmission belt 2 is transmitted between the belt rollers; a driving structure 3 is installed on the belt rollers, and the transmission belt 2 is driven by the driving structure 3. Specifically, similar to the existing belt conveyor drive transmission structure, the driving structure 3 includes a driven pulley installed on the horizontal belt roller, a driving pulley connected to the driven pulley, and a pulley motor that drives the driving pulley to rotate.

[0075] At the same time, similar to the existing belt conveyor structure, the horizontal frame 11 and the overhead frame 12 are equipped with a plurality of rollers 21 supporting the conveyor belt 2.

[0076] During the use of the belt conveyor, as the conveyor belt 2 transports materials for a long time, the conveyor belt 2 wears more and the surface smoothness increases. When conveying materials such as light and highly fluid materials with small particle size, as the loading amount increases, the materials are easily slid down, skidded, stagnated and accumulated on the conveyor belt 2 after being transported to a certain height along the conveyor belt 2, and the materials cannot continue to move upward along the conveyor belt 2. The materials slip and slide down relative to the conveyor belt 2.

[0077] Therefore, in order to fundamentally solve this technical problem, the above-mentioned anti-slip belt conveyor also includes an anti-slip mechanism to prevent the material from slipping; the anti-slip mechanism is arranged at the position of the overhead frame 12 (the above-mentioned slipping, sliding, stagnation, etc. are prone to occur during the material lifting process).

[0078] Specifically, the anti-slip mechanism includes an anti-slip assembly 4 and a traction assembly 6 that pulls the anti-slip assembly 4. The anti-slip assembly 4 also includes an anti-slip plate 43 and a roller structure on which the anti-slip plate 43 is mounted. The traction assembly 6 includes several steel cables for pulling the anti-slip plate 43 upward, a reel structure for winding the steel cables, and a guide wheel structure for guiding the steel cables.

[0079] During normal operation, anti-slip plate 43 maintains a safe distance from the inclined belt to prevent material from being blocked. However, if material slips or slides downward, and subsequent material is continuously accumulated, the material volume gradually increases and rises above anti-slip plate 43. At this point, traction assembly 6 pulls anti-slip plate 43 toward the discharge end of frame 1. Anti-slip plate 43 follows the slope of overhead frame 12 and pushes the material upward, pushing any stagnant or slipping material upward and assisting in the discharge of the material. At this point, material accumulated in the slipping area is removed, allowing the material to flow normally upward under conveyor belt 2. During operation, the feed rate is reduced at the feed end to ensure smooth material flow during the overhead conveying process.

[0080] Due to the properties of the belt (its age, looseness, and smoothness) and the material (its high fluidity), the aforementioned material frequently stagnates and slips during operation. However, the anti-slip mechanism disclosed in the present invention automatically assists in pushing the accumulated, slipping, or sliding material upward. After this push, the accumulated and slipping material is reduced, allowing the conveyor belt 2 to move downward, and normal material transportation can resume. If accumulation, slipping, or sliding occurs again, the mechanism continues to push the material upward.

[0081] When the anti-slip plate 43 assists in raising the material to a position close to the discharge end, the material is normally transported and dropped by the conveyor belt 2. At this time, the downward slope of the overhead frame 12 is utilized. When the reel structure unwinds the steel cable structure, the anti-slip plate 43 quickly descends to prepare for emergency handling of the above situation again.

[0082] When the reel structure winds up the steel cable structure, the anti-slip plate 43 moves upward at an angle, pushing the slipping and accumulated materials accumulated on the conveyor belt 2 upward; when the reel structure unwinds the steel cable structure, the anti-slip plate 43 rolls down through the guide wheel structure by its own gravity, ready to push the materials again.

[0083] The advantages of this structure are that it fundamentally solves the problem of material accumulation and slipping during the elevated belt conveyor process by assisting in pushing the accumulated, slipping, and sliding material upward. This push significantly reduces the amount of material in the accumulation and slipping areas, preventing the material from sliding down the slope of the conveyor belt 2 due to large accumulations and also preventing excessive material accumulation from sliding off the belt edge. Furthermore, it ensures continuous material flow. If material in accumulation and slipping areas is not promptly removed, a continuous stream of material will continue to accumulate there, affecting the smoothness of material transportation.

[0084] During the process of the material being assisted upward by the anti-slip plate 43, due to the large amount of accumulated and slipping material being assisted upward, some of the material is easily dropped outward by the anti-slip plate 43 onto the conveyor belt 2 (the accumulated material is very close to the edge of the conveyor belt 2, and once the anti-slip plate 43 pushes, a large amount of material falls from the edge).

[0085] Therefore, a contouring arm mechanism 8 is installed on the anti-slip plate 43. When the anti-slip plate 43 pushes the slipping material upward, the contouring arm mechanism 8 is used to bring the material on the conveyor belt 2 to the center of the conveyor belt 2 to prevent the material from slipping off the edge of the conveyor belt 2.

[0086] Specifically, the contouring arm mechanism 8 includes a pair of contouring arms that cooperate with each other. During the process of embracing the materials, the contouring arms gather the materials from a scattered state to a stacked state.

[0087] The contoured arm imitates the human arm to hold the material. When the material is close to the edge of the belt, the contoured arm will continuously hold the material from the edge to the center to prevent the material from falling from the edge of the conveyor belt 2.

[0088] Example 2

[0089] like Figure 1-11 As shown, this embodiment discloses the specific structure of the roller structure based on the structure of embodiment 1:

[0090] The roller structure includes a roller shaft 42 fixedly connected to an anti-slip plate 43, with rollers 41 rotatably connected to each end of the roller shaft 42. To ensure the stable up and down movement of the roller structure and the anti-slip plate 43, guide rails 5 are fixedly connected to each side of the overhead frame 12. The guide rails 5 are provided with guide grooves, and the rollers 41 are limited in their rolling motion within the guide grooves.

[0091] At the same time, the anti-slip plate 43 is vertically welded to the roller shaft 42, and the anti-slip plate 43 is vertically arranged to the upward part of the conveyor belt 2, and the anti-slip plate 43 is spaced apart from the conveyor belt 2 (i.e., a safe distance is maintained to avoid blocking the normal transportation of materials).

[0092] At the same time, in order to maintain the posture of the conveyor belt 2 with the anti-slip plate 43 vertically tilted, the roller shaft 42 is positioned (to prevent rotation), and the inner side of the above-mentioned guide rail 5 is fixedly connected with a rail frame 7, and a rectangular sliding opening is opened on the rail frame 7, and the two ends of the roller shaft 42 are respectively limited in the rectangular sliding opening; a guide rail rod 71 is fixedly connected in the rectangular sliding opening, and the guide rail rod 71 passes through the roller shaft 42.

[0093] When the roller shaft 42, roller 41, and anti-slip plate 43 move upward in an inclined direction to push the material, the roller shaft 42 that is limited and slidingly connected to the guide rod 71 cannot rotate on its own. Therefore, the anti-slip plate 43 always maintains a vertical posture relative to the upward inclined conveyor belt 2. This posture can more fully push the material upward.

[0094] Example 3

[0095] like Figure 1-11 As shown, this embodiment is based on the structure of embodiment 2. In the process of pushing the material upward, the material is brought from the outer side of the belt to the center of the belt by the contoured arms to prevent the material from slipping. At the same time, corresponding coordination is made for the shape of the anti-slip plate 43. Specifically, the side walls on both sides of the anti-slip plate 43 are tilted inward to form a slope surface (on the whole, the anti-slip plate 43 is in two parts, one part is a rectangular structure welded to the roller shaft 42, the rectangular structure part is integrally formed into a trapezoidal structure part, and the slope surface is the hypotenuse of the trapezoidal structure). In the process of the anti-slip plate 43 pushing the material upward, the slope surface is used to prevent the two sides of the anti-slip plate 43 from pushing the material toward the edge of the conveyor belt 2.

[0096] Example 4

[0097] like Figure 1-11As shown, this embodiment builds on the structure of Example 3. The cable structure includes two steel cables 64 spaced apart on the left and right sides. The lower end of each steel cable 64 is fixedly connected to the roller shaft 42. Each steel cable 64 specifically includes a lower cable portion 641 that pulls the roller shaft 42. The lower cable portion 641 is guided and bent by the guide wheel structure to form an upper cable portion parallel to the lower cable portion 641. The free end of the upper cable portion is wound around the reel structure.

[0098] The reel structure includes a reel shaft, with reels 62 fixedly connected to both sides of the reel shaft; that is, the free end of each steel cable 64 is reeled and unreeled through each corresponding reel 62. Similarly, the reel 62 structure also includes a motor 61 that drives the reel 62 shaft.

[0099] The motor 61 is a conventional revolving motor 61 disclosed in the prior art. Specifically, the output shaft of the motor 61 is fixedly mounted on the end of the reel 62 shaft by a coupling, in the same manner as the existing motor 61 drives the reel 62 shaft.

[0100] At the same time, according to the existing rotational connection method, lower brackets 65 for rotationally connecting the reel shaft are fixedly connected to both sides of the frame 1 (upright frame portion 12). At the same time, according to the existing fixing method of the motor 61, the motor 61 is fixedly mounted on the lower brackets 65, and a bracket (not shown) supporting the motor 61 is mounted on the lower brackets 65.

[0101] Similarly, the guide wheel structure includes a guide wheel shaft, and guide wheels 63 that cooperate with the reel 62 are fixedly connected to both sides of the guide wheel shaft. The steel cable 64 is guided by the guide wheel 63 to change its posture (specifically, the guide wheel 63 is provided with a guide wheel 63 groove for guiding the steel cable 64).

[0102] In the same way, the upper end both sides of the frame 1 are fixedly connected with the upper bracket 66 of the rotation connection guide wheel 63 shafts. According to the existing rotation connection mode, the bearings matched with the guide wheel shaft and the reel shaft are installed on the upper and lower brackets, and the wheel shaft is rotationally connected with the bearing.

[0103] During operation, when it is necessary to push the material upward in the manner described above to prevent further accumulation of the material, which may lead to downward or sideways sliding, and subsequent accumulation of the material being continuously transferred, the motor 61 drives the reel 62 to reel in the steel cable 64. During the reeling process, the steel cable 64 pulls the roller shaft 42 upward, and correspondingly, the material on the anti-slip plate 43 fixed to the roller shaft 42 is pushed upward. In this process, the use of the steel cable 64 for pulling is intended to, on the one hand, utilize the greater pulling force of the steel cable 64 to push the accumulated material upward in an inclined direction, and on the other hand, the rolling of the roller 41 reduces the upward resistance of the roller shaft 42 and the anti-slip plate 43.

[0104] What is even better is that when the material is pushed to a certain height, the material can be transported normally by the conveyor belt 2. At this time, the anti-slip plate 43, roller shaft 42, and roller 41 can be quickly unwound by the reel 62 (the steel cable 64 is wound in the wheel groove of the reel 62) to quickly slide down along the guide rail 5, rail frame 7, and guide rail rod 71 to the initial position, so as to quickly push the accumulated and slipping materials up again.

[0105] Because the initial positions of the anti-slip plate 43, roller shaft 42, and roller 41 are located between the horizontal part and the raised part of the conveyor belt 2, and the material accumulates and slips after being lifted to a certain height at the raised part of the conveyor belt 2, the material continuously accumulates and slips after passing through the gap between the anti-slip plate 43 and the conveyor belt 2.

[0106] If the anti-slip plate 43, roller shaft 42 and roller 41 cannot be quickly reset to their initial positions, once a large amount of material slips, accumulates or accumulates before the anti-slip plate 43 is reset, the anti-slip plate 43 will be blocked by the material and cannot be reset. Even if it is reset, it will cause the defect of pushing the accumulated material downward.

[0107] However, traditional pushing structures such as air cylinders, hydraulic cylinders, and push plates are unable to push a large amount of material upward and then reset it at a very fast speed.

[0108] While the conveyor belt 2 is conveying materials, the high-speed transmission conveyor belt 2 can form the above-mentioned material accumulation and slippage again in a relatively short time.

[0109] Example 5

[0110] like Figure 1-11 As shown, this embodiment builds on the structure of Example 4. To gather accumulated and slipping materials from the edge of the conveyor belt 2 toward the center while the anti-slip plate 43 pushes the materials upward, thereby preventing the materials from sliding sideways off the conveyor belt 2, a contour-like arm-holding mechanism 8 is designed on the anti-slip plate 43. The contour-like arm-holding mechanism 8 mimics the movements of the human body, gathering the materials in a hugging manner.

[0111] The reason is that the contoured arm mechanism 8 is used to push the material from the edge position toward the center in a hugging manner, which can gather the material to the center of the conveyor belt 2 to the greatest extent and minimize the material slipping from the edge of the belt.

[0112] The contour holding arm mechanism 8 includes a pair of contour holding arms arranged in an articulated manner (the contour holding arms are perpendicular to the anti-slip plate 43, so they are parallel to the inclined belt and a certain safety gap is retained between them). The contour holding arms are arranged in a symmetrical manner so that the materials can be brought from the edge to the center when the contour holding arms on both sides move.

[0113] Example 6

[0114] like Figure 1-11 As shown, this embodiment discloses the specific shape of the contoured arm based on the structure of Example 5.

[0115] Specifically, the contoured arm includes an arm frame 81; a holding arm 84 corresponding in shape to arm frame 81 is fixedly connected to the top of arm frame 81. Holding arm 84 has the same shape as arm frame 81, but is taller than arm frame 81. The height-designed holding arm 84 increases the material holding capacity, achieving maximum material holding.

[0116] Specifically, the inner end of the arm 81 is hinged on the anti-slip plate 43 (the hinge method is: the inner end of the arm 81 is fixedly connected to a pin shaft, and the pin shaft is rotatably connected to the pin shaft seat fixedly connected on the anti-slip plate 43), and the anti-slip plate 43 is hinged with an electric push rod structure that pushes and pulls the arm 81.

[0117] Specifically, the electric push rod structure includes an electric push rod 82 (the electric push rod 82 is a conventional electric telescopic push rod disclosed in the prior art), and the anti-slip plate 43 is fixedly connected to a hinged bracket 821 on which the electric push rod 82 is hinged. Similarly, the electric push rod 82 is fixedly connected to a hinge tongue, which is hinged to the hinge bracket 821 through a pin shaft.

[0118] At the same time, the push end of the electric push rod 82 is fixedly connected to a push rod 83, which is hinged to the top of the holding arm 84. Specifically, the outer end of the push rod 83 is fixedly connected to a hinge seat, and the top of the holding arm 84 is fixedly connected to a fixed support hinged to the hinge seat. The hinge seat and the fixed support are hingedly connected by a pin (the bottom of the pin is fixedly connected to the fixed support and hinged to the hinge seat, and the top of the pin extends through the hinge seat). According to existing methods, the top of the pin is fixedly connected to a cap that blocks the hinge seat to prevent the push rod 83 from detaching from the holding arm 84.

[0119] During operation, with the cooperation of the electric push rods 82 on both sides, the contour holding arms switch from an open position to a closed position. During this process, the accumulated and slipping materials are gathered together by the contour holding arms on both sides.

[0120] The advantage of this method is that it gathers the materials in a hugging manner, while traditional pushing methods such as the push rod 83 can only push the materials from the edge to the center of the conveyor belt 2 and cannot gather the materials. After the materials are gathered, the anti-slip plate 43 can concentrate and fully push the accumulated materials, and can greatly avoid the risk of materials moving toward the outside of the conveyor belt 2 again during the pushing process, causing them to slip.

[0121] Example 7

[0122] like Figure 1-11As shown, based on the structure of Example 6, this embodiment specifically discloses the shape of the arm 81 (the shape of the holding arm 84 is consistent with the shape of the arm 81). Specifically, the arm 81 includes an arc-shaped arm portion 811, the inner end of which is hinged to a hinge seat on the anti-slip plate 43; the outer end of the arc arm portion 811 is integrally formed with a straight arm portion 812, and the straight arm portion 812 is integrally formed with an arm holding portion 813; the arm holding portion 813 is bent inward.

[0123] Driven by the electric push rod 82, the inner curved arm portion 813 first pushes the material on the edge of the conveyor belt 2 toward the center of the belt, where it accumulates close together. Next, the straight arm portion 812 cooperates to further pull the material toward the center. Finally, the material is held in a pile within the gap formed by the two curved arms 811.

[0124] The above-mentioned structural shape frame 81 (holding arm 84) is an arm-shaped structure designed to simulate the posture of the human body when holding materials, which can hold the materials from a scattered state to a gathered state to the greatest extent.

[0125] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
