Description

Technical Field

[0001] This utility model relates to a conveyor belt return material cleaning device, belonging to the technical field of belt conveyor equipment. Background Technology

[0002] Belt conveyors are widely used in various material handling systems. However, during belt transport, material often adheres to the surface of the return belt. If this material is not cleaned in time, it can cause many problems. On the one hand, it can lead to unstable belt operation, increase wear between the belt and rollers / idlers, and reduce the service life of the equipment. On the other hand, falling material can pollute the working environment, increase cleaning costs, and may even affect normal production.

[0003] Currently, common methods for cleaning return conveyor belts include brush cleaning, scraper cleaning, and vibratory cleaning. Brush cleaning has the problem of poor cleaning effect; it is difficult to completely remove materials that are highly viscous or have large particles. While scraper cleaning and vibratory cleaning can remove material to some extent, they can easily scratch the surface of the belt, especially for belts with softer textures or special coatings. Chinese patent ZL202221832693.7, entitled "Vibrating Micro-Power Sweeper," includes a mounting frame installed on the side of the belt conveyor and at least one cleaning roller. The cleaning roller has several evenly spaced vibrating blocks on its circumference, and the top surface of each vibrating block extends to both sides to form flanges, i.e., the cross-section of the vibrating block is T-shaped, forming a T-shaped vibrating structure. The surface of the cleaning roller is covered with a protective layer. The problem is that the T-shaped vibrating structure has sharp edges and corners. Although covered with a protective layer, the working environment is harsh, and the cleaning roller needs to continuously vibrate the belt. Over time, the protective layer is easily damaged, and the T-shaped vibrating structure still poses a risk of damaging the belt surface. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor belt return material cleaning device that can efficiently and non-destructively clean the return belt, improve the operational stability and service life of the belt conveyor; the dropped material falls directly into the receiving chute, which will not pollute the environment, reduce cleaning costs, and solve the problems existing in the background technology.

[0005] The technical solution of this utility model is: A conveyor belt return material cleaning device includes a mounting bracket, a movable rotating shaft, a connecting plate, and a vibrating roller. The mounting bracket mounts the movable rotating shaft, and both ends of the movable rotating shaft are connected to both ends of the vibrating roller via the connecting plate. The vibrating roller is arranged parallel to the width direction of the return belt above the back of the return belt, and the rotation of the return belt drives the vibrating roller to rotate. The vibrating roller includes a vibrating roller shaft, a roller, and vibrating elements. Both ends of the vibrating roller shaft are connected to both ends of the movable rotating shaft via the connecting plate. The vibrating roller shaft is equipped with a roller, and multiple vibrating elements are evenly arranged on the circumferential direction on the surface of the roller. The vibrating elements have smooth surfaces and circular cross-sections. The vibrating elements contact the back of the return belt, and the rotation of the return belt causes the vibrating elements to vibrate the return belt, thereby causing the material on the front of the return belt to fall off.

[0006] The movable shaft is fixed to the mounting bracket by two sets of matching bearing assemblies, providing a movable suspension point with low resistance for the up and down jumping of the vibrating roller, ensuring that the vibrating roller and vibrating components can operate stably.

[0007] The mounting bracket includes side plates and crossbeams. There are two side plates, which are connected by the crossbeam. The side plates and the crossbeam are respectively provided with mounting hole one and mounting hole two. The mounting bracket is fixedly connected to the belt conveyor frame by bolt one and mounting hole one. The mounting bracket is fixedly connected to the bearing assembly by bolt two and mounting hole two.

[0008] The crossbeam is positioned parallel to the return belt above it and perpendicular to the direction of travel of the return belt.

[0009] The connecting plate has mounting holes three at both ends. The two ends of the connecting plate are welded to the vibrating roller shaft and the movable shaft through the mounting holes three, respectively, to ensure a reliable connection between the vibrating roller and the movable shaft.

[0010] The return conveyor belt is provided with a receiving chute below it. The material on the front of the return conveyor belt falls into the receiving chute after being vibrated by the vibrating roller.

[0011] The roller is a return idler of the same model as the conveyor belt. The roller has a hollow structure and is made of high-strength steel to ensure sufficient strength.

[0012] The number of vibrating components is six, and the vibrating components are made of round steel with a diameter of 20 mm. The six round steels are evenly and firmly welded to the outer circumference of the roller. The diameter of the round steel of the vibrating components can be adjusted according to the diameter of the return idler roller of the conveyor. If the number of vibrating components is less than 6, the vibrating roller may not rotate. If there are more than 6, the vibrating effect will be reduced. Therefore, the optimal number of vibrating components is 6.

[0013] The bearing assembly, movable shaft, and return belt are all commonly known and used equipment in the field.

[0014] When the belt conveyor is running, no external driving force is required. The return belt drives the rollers and vibrating elements of the vibrating roller to rotate. As the roller rotates, the vibrating elements on the vibrating roller continuously contact the back of the return belt, vibrating the material adhering to the front of the return belt and causing the material to fall into the receiving chute. The constant frequency vibration of the vibrating elements can effectively remove the adhering material, achieving the purpose of cleaning the belt.

[0015] The beneficial effects of this utility model are: the high-frequency vibration of the vibrating component can effectively remove the material adhering to the front of the return belt without damaging the belt, making the cleaning more thorough and greatly improving the cleanliness of the belt; the dropped material falls directly into the receiving chute, which will not pollute the environment and reduce cleaning costs; it is highly adaptable, has a simple structure, and is easy to install and maintain.

[0023] The return belt 6 is provided with a receiving chute below it. The material on the front of the return belt falls into the receiving chute after being vibrated by the vibrating roller.

[0024] The roller is a return idler of the same model as the conveyor belt. The roller has a hollow structure and is made of high-strength steel to ensure sufficient strength.

[0025] The number of vibrating components is six, and the vibrating components are made of round steel with a diameter of 20 mm. The six round steels are evenly and firmly welded to the outer circumference of the roller 52. The diameter of the round steel of the vibrating components can be adjusted according to the diameter of the return idler roller of the conveyor. If the number of vibrating components is less than 6, the vibrating roller may not rotate. If there are more than 6, the vibrating effect will be reduced. Therefore, the optimal number of vibrating components is 6.

[0026] In this embodiment, refer to the appendix. Figure 1-4 A conveyor belt return material cleaning device includes a mounting bracket 1, a movable rotating shaft 3, a connecting plate 4, and a vibrating roller 5. A suitable installation position is selected based on the frame structure and dimensions of the belt conveyor, and the mounting bracket 1 is fixed to the belt conveyor frame with bolts to ensure accurate positioning. The movable rotating shaft 3 is mounted on the mounting bracket 1, and the connecting plate 4 connects the movable rotating shaft 3 and the vibrating roller shaft 51. The roller 52 of the vibrating roller 5 is mounted on the back of the return belt, and the rotation of the return belt drives the roller 52 of the vibrating roller 5 to rotate.

[0027] The vibrating roller 5 includes a vibrating roller shaft 51, a roller 52, and six vibrating components 53. The roller 52 is a return parallel idler roller of the same model as the conveyor belt. It has a hollow structure and is made of high-strength steel to ensure sufficient strength. The six vibrating components are made of 20 mm diameter round steel, which are evenly distributed and firmly welded to the outer circumference of the roller. It should be noted that the diameter of the round steel of the vibrating components can be adjusted according to the diameter of the return idler roller of the conveyor. If there are fewer than 6, the vibrating roller may not rotate. If there are more than 6, the vibrating effect will be reduced. The finished vibrating roller is placed on the back of the return belt 6.

[0028] The movable shaft 3 is fixed to the mounting bracket 1 by two sets of matching bearing assemblies 2, providing a movable suspension point with low resistance for the up and down jumping of the vibrating roller, ensuring that the vibrating roller and vibrating components can operate stably.
