Description

Technical Field

[0001] This application relates to the field of transmission and cleaning technology, and in particular to a novel single-line cleaner with high degree of freedom and self-compensation. Background Technology

[0002] In bulk material conveying scenarios such as mines and ports, inclined conveyor belts are key equipment for vertical or inclined lifting and transporting materials, and their operational stability directly affects the efficiency and safety of the entire conveying system. However, in actual operation, when the conveyed material flow exceeds the design capacity, inclined conveyor belts often face significant material control challenges: excessive coal chunks are prone to sliding from the bearing surface onto the return conveyor belt due to gravity, centrifugal force, and belt vibration. This coal chunk falling phenomenon not only causes material spillage along the line, leading to material loss, environmental pollution, and increased subsequent cleaning and maintenance costs; more seriously, the loose coal chunks on the return conveyor belt pose a high risk of being caught in the drums as the belt runs—once the coal chunks enter the gap between the drum and the belt, it may cause belt misalignment, scratches, or even equipment failures such as drum jamming and motor overload. In extreme cases, it may even cause a fire due to frictional overheating, posing a serious threat to production safety. Currently, conveyor belt cleaning mainly focuses on the immediate cleaning of the carrying surface. However, there is a lack of effective active cleaning devices for materials scattered on the return surface due to abnormal operating conditions. This leads to the long-term existence of the above problems, which are difficult to eradicate and will eventually damage the operation of the overall conveyor equipment. If conventional single-strip cleaners are installed for cleaning, the rubber is prone to uneven wear. Therefore, additional belt pressure rollers are required to stabilize and flatten the conveyor belt to ensure the cleaning effect, which increases the overall material and construction costs. Furthermore, the wear of the rubber requires frequent manual adjustment of the base to achieve the cleaning effect, which also increases labor costs. Utility Model Content

[0003] This device provides a novel, highly flexible, self-compensating linear sweeper, the specific implementation of which is as follows: A novel, highly flexible, self-compensating linear sweeper includes: The sweeper includes a first channel steel and a second channel steel, both of which are connected to a connecting rod arranged at an angle via a connecting seat; The end of the connecting rod is vertically slidably connected to the connecting seat, and a heavy-duty spring is provided at the connection. A rubber scraper is provided below the connecting rod. The cleaner is horizontally arranged above the return section of the belt. The rubber scraper elastically abuts against the belt through the heavy-duty spring, and the rubber scraper is obliquely arranged to directionally drive away the coal material adhering to the belt.

[0004] Preferably, the belt has a first guide cylinder, a tail roller, and a second guide cylinder at both ends of the forward section, and a support cylinder and an upper redirecting roller for guiding at the return section.

[0005] Preferably, the sweeper has a pair on the belt, which are respectively located between the first guide cylinder and the tail roller and between the support cylinder and the upper redirecting roller.

[0006] Based on the above technical solutions, this cleaner adopts a multi-point coordinated installation scheme on the belt. By deploying it on the return surface of the belt, it constructs an all-round barrier against coal block entrapment, avoiding the risk of damage to the equipment caused by foreign objects getting stuck.

[0007] Preferably, one end of the connecting rod is connected to the second connecting seat via a positioning pin, and the other end of the connecting rod is connected to the first connecting seat via a positioning pin.

[0008] Preferably, a heavy-duty spring is provided on the outside of the positioning pin, and the two ends of the heavy-duty spring abut against the first connecting seat and the connecting rod, respectively.

[0009] Preferably, the top of the connecting rod is provided with several counterweights, and the counterweights are evenly distributed along the length of the connecting rod.

[0010] Based on the above technical solutions, the sweeper is equipped with a self-compensating structure consisting of a heavy-duty spring and an adjustable counterweight. The operator can adjust the pressure parameters of the sweeper by increasing or decreasing the number of weights according to the hardness of the cleaning surface. As the edge of the rubber gradually wears down, the extension of the spring increases simultaneously, pushing the rubber as a whole to slowly move downwards. Meanwhile, the constant gravity of the weights ensures the stability of the contact pressure. The combined effect of both controls the wear rate deviation of different areas of the rubber to within 5%.

[0011] Preferably, each positioning pin is coaxially provided with a locking key, which is used to lock the angle between the connecting rod and the second connecting seat.

[0012] Based on the above technical solution, the sweeper is a three-sided channel steel structure consisting of a connecting rod, a first channel steel, and a second channel steel. The connecting rod is arranged diagonally, and the distance between the first and second channel steels can be adjusted according to the actual position requirements. The positioning pin and the connecting seat are connected by rotation, and the angle can be flexibly adjusted to adapt to different working conditions. The locking key adopts a conventional threaded bolt structure. After being adjusted to the preset position, simply tightening the bolt will allow its threads to quickly and firmly lock the positioning pin, ensuring connection strength and simplifying the operation process. Fixing can be completed without professional tools. The positioning pin can be integrated with the connecting rod.

[0013] In summary, this application includes the following beneficial technical effects: 1. This utility model ensures that coal blocks will not be rolled into the drums and thus prevent equipment damage by installing the cleaner on the return surface of the conveyor belt, at the tail drum and the upper redirecting drum. 2. This utility model has a simple structure. The sweeper can be welded to the conveyor frame at any position via channel steel. The sweeper is easy to disassemble as a whole. The sweeper is connected by bolts on three sides of channel steel and can be made in different lengths according to the position requirements. 3. This utility model has a self-compensating structure on the sweeper. Through the adjustable counterweight and heavy load spring, the rubber of the sweeper is worn evenly, reducing the cost of manual adjustment. Attached Figure Description
