Description

Technical Field

[0001] The utility model relates to the technical field of mining belt conveyors for preventing backhaul material scattering, in particular to a mining belt conveyor for preventing backhaul material scattering. Background Technique

[0002] A mining belt conveyor (also known as a conveyor belt system or belt conveyor) is a device widely used in the mining industry and other industrial fields for transporting materials such as ores, coals, and sands. It transports materials from one location to another through a continuous belt structure and has efficient and reliable transportation capabilities.

[0003] For example, a belt conveyor with the publication number CN209306386U includes a head pulley, a tail pulley, a belt, and a power device. Among them, the head pulley is located at one end of the belt conveyor and is connected to the power device. The tail pulley is located at the other end of the belt conveyor. The belt is sleeved on the head pulley and the tail pulley. The head pulley drives the tail pulley to rotate through the belt. At least two idler devices are also arranged between the head pulley and the belt. The setting of the idler devices disengages the belt from the head pulley, making the belt in line contact (or less surface contact) with the head pulley and moving by relying on friction, thereby avoiding the situation where the linear velocity of the belt increases at the head pulley, resulting in relative displacement between positions on the belt, greatly extending the service life of the belt, and further improving the service life and working reliability of the belt conveyor.

[0004] In the above patent, it is proposed that the relative displacement between positions on the belt can be avoided by using idler devices, greatly extending the service life of the belt. However, during the use of the belt conveyor, due to the reasons of the space at the head of the belt conveyor, the installation position and angle of the original polyurethane scraping plate are unreasonable, resulting in poor material cleaning effect.

[0005] Therefore, we propose a mining belt conveyor for preventing backhaul material scattering to solve the above-mentioned problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a mining belt conveyor for preventing backhaul material scattering to solve the problem that in the process of using the belt conveyor, due to the reasons of the space at the head of the belt conveyor, the installation position and angle of the original polyurethane scraping plate are unreasonable, resulting in poor material cleaning effect as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A mining belt conveyor for preventing material scattering during return, comprising a frame and a mounting seat arranged at the upper end of the frame. A belt conveyor structure is arranged inside the mounting seat for conveying materials. A polyurethane scraper is installed at the head of the belt conveyor structure. A fixing plate is arranged below the frame. A receiving plate is arranged on one side of the fixing plate. The top end of the receiving plate is placed below the belt conveyor structure. A scraping structure is arranged on one side of the receiving plate for scraping and cleaning the belt conveyor structure;

[0008] The scraping structure includes a channel steel skeleton arranged at the lower end of the frame and a conveyor belt arranged on one side of the channel steel skeleton. Flat iron pieces are arranged on the outer side of the conveyor belt. A number of bolts are evenly distributed on the surface of the flat iron pieces. The channel steel skeleton is placed at the gap between the belt conveyor structure and the receiving plate and is fixed by the flat iron pieces and bolts, so that the conveyor belt can be installed at the lower end of the belt conveyor structure to scrape and clean the belt conveyor structure.

[0009] Preferably, the belt conveyor structure includes a motor arranged outside the mounting seat and a conveying roller connected to the output end of the motor. There are two groups of conveying rollers, and the two groups of conveying rollers are respectively arranged between the two mounting seats. A conveying belt for conveying materials is wound around the outer sides of the two groups of conveying rollers.

[0010] Preferably, the belt conveyor structure further includes a bracket arranged on the frame and a guide roller arranged inside the bracket. The guide roller is in contact with the side wall of the conveying belt.

[0011] Preferably, baffle plates are arranged on the side wall of the receiving plate. There are two groups of baffle plates, which are respectively arranged on the front and rear sides of the receiving plate.

[0012] Preferably, a connecting rod is arranged inside the bracket. A cylinder part is arranged at the upper end of the connecting rod. The telescopic end of the cylinder part is connected to a connecting frame. An adjusting roller is arranged inside the connecting frame. When the cylinder part is started, it can push the connecting frame and the adjusting roller to move, so that the adjusting roller can move towards the conveying belt, and the tension of the conveying belt can be adjusted.

[0013] Preferably, there are two groups of the cylinder part and the connecting frame, and the cross-section of the connecting frame is in an inverted L shape to be able to install the adjusting roller.
