Description

Technical Field

[0001] This utility model relates to the field of tubular belt conveyor technology, specifically a tubular belt conveyor with anti-side leakage. Background Technology

[0002] A tubular belt conveyor, also known as a tubular belt conveyor, is a device that forcibly coils a conveyor belt into a closed circular tube to transport materials, combining the advantages of both pipeline conveying and belt conveying.

[0003] However, when conveying granular materials, the material is prone to falling off the edges of the conveyor belt, resulting in material waste. Furthermore, when conveying granular materials for a long time, the material enters the gaps between the sides of the conveyor belt and the support frame, causing blockages and affecting the wear and tear of the conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide a tubular belt conveyor with anti-leakage design to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A leak-proof tubular belt conveyor includes a conveyor frame, with rotating rollers located near both ends in the middle of the conveyor frame, a conveyor belt sleeved between the two rotating rollers, skirt belts located on both sides of the outer wall of the conveyor belt, and a guide structure for winding the conveyor belt located in the middle of the conveyor frame.

[0007] The guide structure includes two sets of symmetrical side plates. Each set of side plates is provided with a lower support plate and an upper support plate. A slot is provided between the lower support plate and the upper support plate. Several guide rollers are provided between the slots. Several second support rollers are also provided between the two lower support plates.

[0008] Furthermore, a motor is provided on the outer wall of the conveyor frame. The motor is fixedly connected to the conveyor frame by screws. The output shaft of the motor is coaxially connected to one of the rotating rollers. The rotating roller is rotatably connected to the conveyor frame through a rotating shaft.

[0009] In this invention, the motor is electrically connected to an external power source via a wire, and the motor is started by a control switch on its outer wall. The output shaft of the motor is connected to the shaft of one of the rotating rollers via a coupling, so that the output shaft rotates and drives one of the rotating rollers to rotate continuously.

[0010] Specifically, several first rollers are provided at both ends of the middle of the conveyor frame, and the first rollers are rotatably connected to the conveyor frame through a rotating shaft.

[0011] In this invention, the first idler roller rotates in coordination with the conveyor frame to support both ends of the conveyor belt sleeved in the middle of the conveyor frame, thereby reducing the impact of material conveying caused by slumping under gravity.

[0012] It should be noted that both the lower support plate and the upper support plate are fixedly connected to the inner wall of the conveyor frame by screws. The lower support plate and the upper support plate are combined to form a right-angled trapezoidal shape, and the width of the lower support plate is greater than the width of the upper support plate.

[0013] In this invention, the lower support plate and the upper support plate work together to roll up and guide the middle part of the conveyor belt, curling the conveyor belt into a tubular shape for stable material conveying.

[0014] Furthermore, the guide rollers are evenly spaced and are rotatably connected to the corresponding upper and lower support plates via rotating shafts.

[0015] In this invention, multiple guide rollers work together to guide and roll up the edge of the conveyor belt, and the guide rollers rotate flexibly to facilitate continuous conveying of the conveyor belt.

[0016] Furthermore, the two ends of the second idler are rotatably connected to the corresponding lower support plate via rotating shafts, and the second idler is distributed at equal intervals.

[0017] In this invention, the second idler roller, in conjunction with the second idler roller, lifts the bottom of the middle rolled-up position of the conveyor belt, reducing the impact of the conveyor belt sagging due to gravity on the conveyed material.

[0018] It is worth noting that the skirt belt is wavy and made of rubber. The conveyor belt is also made of rubber. The skirt belt and the conveyor belt are integrally formed. The inner wall of the conveyor belt is in close contact with the rollers near the left and right sides. The upper surface of the first idler roller is in close contact with the bottom of the conveyor belt. The upper surface of the second idler roller is in close contact with the middle of the inner wall of the conveyor belt. The top surface of the guide roller is in close contact with the side of the inner wall of the conveyor belt.

[0019] In this invention, the wavy skirt belt, when used in conjunction with the belt, can stably extend at both the bend at the end of the conveyor belt and the roll-up position in the middle of the conveyor belt, intercepting the material being conveyed in the middle, reducing the impact of material falling from the side, and reducing the impact of material falling from the side of the conveyor belt into the gap between the conveyor belt and the conveyor frame, thus preventing blockage and wear on the conveyor belt. The guide roller, the first idler roller, and the second idler roller are all in close contact with the inner wall of the conveyor belt, stably lifting and guiding the material, facilitating stable material conveying.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model features a conveyor belt winding guide structure on the conveyor frame. With the cooperation of two sets of upper and lower support plates, the middle section of the conveyor frame is defined. Multiple guide rollers are used between the upper and lower support plates on the same side to guide the conveyor belt to wind up from the side. A second idler roller is used between the two lower support plates to support the bottom of the conveyor belt at the winding position. With the cooperation of the first idler roller, the two ends of the conveyor end are supported, reducing the impact of the conveyor belt falling under the action of gravity. Skirt belts are used on both sides of the outer wall of the conveyor belt to intercept the material conveyed on the upper surface of the conveyor belt and reduce the spillage of the conveyed material from the side.

[0022] 2. This utility model provides power to the whole by setting a motor. The output shaft of the motor is coaxially connected to the shaft of one of the rotating rollers through a coupling. The conveyor belt is in close contact with the rotating roller. Under the action of friction, the rotating roller rotates and drives the conveyor belt to run continuously. The two ends of the conveyor belt are horizontal and the middle of the conveyor belt is rolled up into a tube shape, which helps to stably transport materials while the conveyor belt runs continuously.

[0033] 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.

[0034] Please see Figures 1-5 This embodiment provides a technical solution:

[0035] A leak-proof tubular belt conveyor includes a conveyor frame 1, with rotating rollers 10 located near both ends of the conveyor frame 1, and a conveyor belt 2 sleeved between two rotating rollers 10. Several first idlers 11 are located at both ends of the conveyor frame 1, and the first idlers 11 are rotatably connected to the conveyor frame 1 via a rotating shaft.

[0036] In this utility model, the first idler roller 11 rotates with the conveyor frame 1 to support both ends of the conveyor belt 2 sleeved in the middle of the conveyor frame 1, thereby reducing the impact of material conveying caused by falling under the action of gravity.

[0037] Furthermore, skirt belts 3 are provided on both sides of the outer wall of the conveyor belt 2, and a guide structure for the winding of the conveyor belt 2 is provided in the middle of the conveyor frame 1.

[0038] It should be noted that the guide roll structure includes two sets of symmetrical side plates. Each set of side plates is provided with a lower support plate 12 and an upper support plate 13. A slot 14 is provided between the lower support plate 12 and the upper support plate 13. Several guide rollers 15 are provided between the slots 14. Several second support rollers 16 are also provided between the two lower support plates 12.

[0039] Furthermore, both the lower support plate 12 and the upper support plate 13 are fixedly connected to the inner wall of the conveyor frame 1 by screws. The lower support plate 12 and the upper support plate 13 are combined to form a right-angled trapezoidal shape, and the width of the lower support plate 12 is greater than the width of the upper support plate 13.

[0040] In this utility model, the lower support plate 12 and the upper support plate 13 cooperate to roll up and guide the middle part of the conveyor belt 2, and roll the conveyor belt 2 into a tubular shape to stably transport materials.

[0041] Specifically, the guide rollers 15 are evenly spaced and are rotatably connected to the corresponding upper support plate 13 and lower support plate 12 via rotating shafts.

[0042] In this invention, with the cooperation of multiple guide rollers 15, the edge of the conveyor belt 2 is guided and rolled up, and the guide rollers 15 can rotate flexibly to facilitate the continuous conveying of the conveyor belt 2.

[0043] Secondly, the two ends of the second roller 16 are rotatably connected to the corresponding lower support plate 12 through rotating shafts, and the second roller 16 are distributed at equal intervals.

[0044] In this invention, the second idler roller 16, in conjunction with the second idler roller 16, lifts the bottom of the middle rolled-up position of the conveyor belt 2, reducing the impact of the conveyor belt 2 sagging due to gravity on the conveyed material.

[0045] Furthermore, a motor 4 is provided on the outer wall of the conveyor frame 1. The motor 4 is fixedly connected to the conveyor frame 1 by screws. The output shaft of the motor 4 is coaxially connected to one of the rotating rollers 10. The rotating roller 10 is rotatably connected to the conveyor frame 1 through a rotating shaft.

[0046] In this invention, the motor 4 is electrically connected to an external power source via a wire, and the motor 4 is started by a control switch on its outer wall. The output shaft of the motor 4 is connected to the shaft of one of the rollers 10 via a coupling, so that the output shaft rotates and drives one of the rollers 10 to rotate continuously.

[0047] It is worth noting that the skirt belt 3 is wavy and made of rubber. The conveyor belt 2 is also made of rubber. The skirt belt 3 and the conveyor belt 2 are integrally formed. The inner wall of the conveyor belt 2 is in close contact with the roller 10 near the left and right sides. The upper surface of the first idler roller 11 is in close contact with the bottom of the conveyor belt 2. The upper surface of the second idler roller 16 is in close contact with the middle of the inner wall of the conveyor belt 2. The top surface of the guide roller 15 is in close contact with the side of the inner wall of the conveyor belt 2.

[0048] In this invention, the wavy skirt belt 3, when used in conjunction with the bend at the end of the conveyor belt 2 and the rolled-up position in the middle of the conveyor belt 2, can stably extend to intercept the material being conveyed in the middle, reducing the impact of material falling from the side and reducing the impact of material falling from the side of the conveyor belt 2 into the gap between it and the conveyor frame 1, thus preventing blockage and wear on the conveyor belt 2. The guide roller 15, the first idler roller 11, and the second idler roller 16 are all in close contact with the inner wall of the conveyor belt 2, stably lifting and guiding the material, facilitating stable material conveying.

[0049] In this embodiment of the anti-leakage tubular belt conveyor, when in use, firstly, two sets of guide winding structures for winding the conveyor belt 2 are installed on the conveyor frame 1. The lower support plate 12 and the upper support plate 13 are fixed on the conveyor frame 1 with screws, and multiple guide rollers 15 are respectively installed between two slots 14. The upper end of the guide roller 15 is rotatably connected to the upper support plate 13, and the lower end of the guide roller 15 is rotatably connected to the lower support plate 12. Then, the two ends of multiple second idler rollers 16 are rotatably connected to the corresponding lower support plate 12, and the first idler roller 11 is rotatably connected to the conveyor frame 1. The conveyor belt 2 with the skirt belt 3 is sleeved on the two rotating rollers 10.

[0050] When materials need to be conveyed, the conveyor belt 2 with skirted belt 3 is made of rubber and has toughness. With the cooperation of the guide roller 15, the middle section of the conveyor belt 2 is guided to roll inward to form a tubular structure. The tops of the skirted belt 3 on the tubular part of the conveyor belt 2 are close to each other. The two ends of the conveyor belt 2 are kept horizontal near the position of the rotating roller 10. The motor 4 is installed on the outer wall of the conveyor frame 1. When the control switch on the motor 4 is turned on, the output shaft rotates and drives the rotating roller 10 to rotate. Under the action of friction, the conveyor belt 2 can run continuously. With the cooperation of the skirted belt 3, the leakage of materials from the side of the conveyor belt 2 is reduced, which causes material waste. At the same time, it prevents materials from entering the gap between the conveyor belt 2 and the conveyor frame 1, reducing the impact of wear and tear on the outer wall of the conveyor belt 2. The first idler roller 11 and the second idler roller 16 support the bottom of the conveyor belt 2 to prevent it from falling under the action of gravity and affecting the conveying.
