Description

Technical Field

[0001] This utility model relates to the field of belt conveyor equipment, and in particular to a belt conveyor with a cleaning device. Background Technology

[0002] Belt conveyors are a common type of industrial and agricultural transportation equipment, commonly known as conveyor belts. Most are made of rubber, which facilitates movement by rollers and allows for easy elastic deformation. Furthermore, a significant number of belt conveyors operate with a concave curve in the conveyor belt shape, allowing for the loading of more material while preventing spillage during transport.

[0003] Belt conveyors offer high transport efficiency, but they also have certain drawbacks, requiring frequent cleaning, especially for granular or powdery materials such as sand, coal, and flour, which easily adhere to the conveyor belt surface. Current technology equips belt conveyors with various types of cleaning devices.

[0004] Some cleaning devices have very complex structures. In fact, for users, the simpler the structure of the device, the lower the maintenance cost and the less likely it is to be damaged. Utility Model Content

[0030] The technical solution of this utility model and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0031] The belt conveyor with a cleaning device provided by this utility model, such as Figure 1 and Figure 2 As shown, the system includes a long strip support 100, a scraper 200, a rubber conveyor belt (not shown in the figure), and several conveyor rollers 300. Reversing rollers 110 are provided at both ends of the long strip support 100. The conveyor rollers 300 are distributed in two rows along the length of the long strip support 100, and both rows of conveyor rollers 300 have an inclination angle toward the central axis of the long strip support 100. The rubber conveyor belt is wound around the conveyor rollers 300 and the reversing rollers 110. The scraper 200 is located at the outlet end of the long strip support 100 and can abut against the flat surface of the rubber conveyor belt on the reversing roller 110.

[0032] A rubber conveyor belt is wound between two reversing rollers 110 and, supported and driven by the conveyor rollers 300, reciprocates along the circumference of the elongated support 100. The conveyor rollers 300 are not horizontally positioned, but rather arranged with a lower center and higher sides. In one specific implementation, such as... Figure 3 As shown, the plane containing the central axis of the conveyor roller 300 makes an angle of 5° to 10° with the horizontal plane. After the rubber conveyor belt is loaded with material, it will naturally curve. When the rubber conveyor belt winds around the reversing roller 110, transitioning from the upper to the lower layer, the rubber conveyor belt is stretched flat by the reversing roller 110. After unloading the material, the rubber conveyor belt is easily cleaned by the scraper, resulting in very few cleaning dead zones. Compared to the traditional method of placing the cleaning device on the lower conveyor belt of a belt conveyor, the belt conveyor provided by this invention has a very simple structure. By utilizing the structure of the belt conveyor itself and placing a scraper 200 at an appropriate position, high-efficiency cleaning can be achieved.

[0033] The belt conveyor with cleaning device provided by this utility model is based on the traditional belt conveyor. A scraper 200 with a special posture is set at the outlet end of its long strip support 100. The top edge of the scraper 200 can abut against the flat surface of the rubber conveyor belt. Taking advantage of the fact that the rubber conveyor belt can be flattened at the beginning of the return stroke and is most easily cleaned by the scraper 200, the belt conveyor achieves high-efficiency and low-maintenance transmission work with the simplest structure.

[0034] Specifically, in one of the first embodiments of this utility model, such as Figure 1 and Figure 2As shown, a mounting frame 120 is provided at the outlet end of the elongated support 100. Elongated through holes 121 are provided on both sides of the mounting frame 120. The plane containing the central axis of the elongated through holes 121 intersects the central axis of the reversing roller 110. The plane containing the central axis of the elongated through holes 121 forms an angle β of 20° to 35° with the horizontal plane. The scraper 200 is detachably connected to the mounting frame 120 through the elongated through holes 121. When the plane containing the central axis of the elongated through holes 121 forms an angle of 20° to 35° with the horizontal plane, and this plane passes through the central axis of the reversing roller 110, the plane containing the scraper 200 forms an angle of 20° to 35° with the horizontal plane. This ensures that the scraper 200 does not affect the natural unloading of the rubber conveyor belt, and also ensures that the scraper 200 rests against the rubber conveyor belt on the flattest possible surface.

[0035] In conjunction with the foregoing embodiments, in one implementation, such as Figure 4 As shown, the scraper 200 has two threaded holes 201 on both sides along its length. The scraper 200 is connected to the mounting bracket 120 by bolts passing through the elongated through holes 121. Through the threaded holes 201, bolts, and elongated through holes 121, the distance between the scraper 200 and the reversing roller 110 can be adjusted, which essentially allows adjustment of the gap or contact force between the scraper 200 and the rubber conveyor belt.

[0036] Optionally, in the second embodiment of this utility model, such as Figure 5 As shown, the diameter of the reversing roller 110 at the outlet end varies along its own axis, gradually increasing from both sides towards the middle. In a more specific embodiment, the ratio of the maximum diameter to the minimum diameter of the reversing roller 110 is 1.2. The reversing roller 110 at the outlet end of the elongated support 100 adopts a varying diameter, with a larger diameter near the middle and smaller diameters on both sides, which better counteracts the concave center and convex sides of the rubber conveyor belt, ensuring a smoother surface on the reversing roller 110.

[0037] Optionally, in a third embodiment of this utility model, such as Figure 6 As shown, the scraper 200 includes a mounting base 210 and a blade 220. The blade 220 is detachably mounted on the mounting base 210, which is connected to a long strip support 100. In a more specific implementation, the mounting base 210 is made of metal and has receiving spaces with inlet and outlet. The mounting base 210 is a container with receiving space that can hold circulating water to facilitate cooling of the scraper 200 and improve its service life. Additionally, as... Figure 4 and Figure 6As shown, the blade 220 of the scraper 200 can also be configured as a serrated or continuously undulating curve, which can make the working area of ​​the scraper 200 edge longer and improve the scraping force on the rubber conveyor belt.
