Description

Technical Field

[0001] The invention relates to the field of material transport belt cleaners, and in particular to a rotary belt cleaning device. Background Art

[0002] Belt conveyors are widely used in all walks of life and are important equipment for transporting materials. At present, belt conveyors are mostly used for transporting raw coal in coal mines. In the process of transporting raw coal from coal mines, some materials containing moisture and stickiness often adhere to the working surface of the belt during the transmission process. The adhered materials fall everywhere, making the entire belt conveyor, the conveyor belt and the surrounding environment poor. At this time, personnel are required to clean it every day or irregularly. Not only is the labor intensity high, but cleaning the running belt conveyor will also bring hidden dangers to the safety of personnel; currently, belt conveyors usually use non-metallic scrapers to clean the belt surface. The scraper will cause certain damage to the belt, especially the belt connection due to friction with the belt, and the scraper will wear faster, the cost is increased, and the use is limited. Summary of the invention

[0003] The purpose of the present invention is to provide a rotary belt cleaning device to improve the cleaning efficiency of the belt, solve the wear of the belt by non-metallic scrapers, reduce the workload of personnel cleaning the belt, and eliminate the safety hazards caused by manual belt cleaning.

[0004] The technical solution of the present invention is as follows:

[0005] The present invention discloses a rotary belt cleaning device, comprising a mounting bracket, a gear transmission system, a rotating shaft and a rotating cleaning head; the mounting bracket base is fixed on the belt bracket, the mounting bracket is fixed with the gear transmission system, the rotating shaft is mounted on the mounting bracket by means of positioning bolts, the rotating shaft is fixed with the rotating cleaning head at the lower end of the rotating shaft, and the gear transmission system drives the rotating shaft to move.

[0006] Furthermore, the gear transmission system is connected to the belt drive motor through a chain. While the drive motor drives the belt to rotate, it can also drive the gear transmission system to move through the chain. The two share one motor, saving electricity resources.

[0007] Furthermore, the gear transmission system includes a primary gear and a secondary gear, which are meshed with each other to realize the rotational movement of the rotating shaft. The gear transmission system utilizes the principle of a gear reducer to make the rotation speed of the cleaning device lower than the speed of the belt, thereby achieving a rotational cleaning effect on the belt.

[0008] Furthermore, the rotary cleaning head includes a cleaning brush fixing seat and a cleaning brush, wherein the cleaning brush is fixed on the cleaning brush fixing seat, and the cleaning brush fixing seat is connected to the rotating shaft so that the cleaning brush can rotate with the rotating shaft.

[0009] Furthermore, the cleaning brush is a blade fan type cleaning brush, which can effectively reduce the wear of the belt and increase the cleaning area. It can generate a stronger airflow through rotation and effectively sweep away the attachments on the belt surface.

[0010] Furthermore, the blade-fan type cleaning brush is made of wear-resistant material, thereby increasing the service life of the cleaning brush.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The blade-fan type cleaning brush and the rotary cleaning method of the present invention greatly enhance the cleaning force and effectively improve the belt cleaning efficiency.

[0013] 2. The present invention reduces the wear of the cleaning device on the belt and prolongs the service life of the belt through reasonable gear reduction design and material selection.

[0014] 3. The automated cleaning of the present invention reduces the frequency and intensity of manual cleaning, reduces the workload of personnel, and improves the safety of belt cleaning personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0019] See also Figure 1, this embodiment discloses a rotary belt cleaning device, including a mounting bracket 1, a gear transmission system, a rotating shaft 5 and a rotary cleaning head 6;

[0020] The base of the mounting bracket 1 is fixed to the belt bracket 9 by bolts, and is firmly fixed to the belt bracket 9 by bolts, thereby ensuring the stability of the entire device;

[0021] A gear transmission system is fixed on the mounting bracket 1, and the gear transmission system includes a primary gear 3 and a secondary gear 4. The primary gear 3 and the secondary gear 4 cooperate with each other to form a more stable gear transmission system with higher power transmission efficiency, which effectively improves the working efficiency and reliability of the cleaning device;

[0022] The driving motor 2 is connected to the gear transmission system through a chain, and the rotating shaft 5 is installed on the mounting bracket 1 through positioning bolts. A rotating cleaning head 6 is fixed to the lower end of the rotating shaft 5. The driving motor 2 can drive the gear transmission system to move through the chain while driving the belt to operate. The two share one motor, which effectively saves electricity resources.

[0023] The first-stage gear 3 and the second-stage gear 4 utilize the principle of the gear reducer to drive the rotating shaft 5 to move so that the rotation speed of the cleaning device is lower than the running speed of the belt, thereby achieving a rotational cleaning effect on the belt, and ensuring that the cleaning brush can maintain stable contact with the belt, while avoiding belt wear caused by excessive speed.

[0024] Preferably, the rotary cleaning head 6 includes a cleaning brush fixing seat 7 and a cleaning brush, wherein the cleaning brush is fixed on the cleaning brush fixing seat 7 , and the cleaning brush fixing seat is connected to the rotating shaft 5 , so that the cleaning brush can rotate with the rotating shaft 5 .

[0025] Preferably, the cleaning brush is a blade fan type cleaning brush, which increases the cleaning area, can effectively reduce the wear on the belt, and can also generate stronger airflow through rotation to effectively sweep away attachments on the belt surface.

[0026] Preferably, the fan-type cleaning brush is made of wear-resistant material to increase the service life of the cleaning brush; the cleaning brush material can be selected according to actual cleaning needs, such as wear-resistant steel brush, highly elastic polyurethane or special fiber tape, to meet the cleaning needs of different materials.

[0027] Preferably, the rotating shaft 5 can adjust the distance between the rotating cleaning head 6 and the belt through a positioning bolt, adjust the contact pressure and position of the cleaning brush and the belt, and through the rotating shaft 5, the bristles of the cleaning brush are in slight contact with the belt surface to ensure the cleaning effect.

[0028] Preferably, the installation method of the present invention is to fix the device to the belt bracket 9 with bolts. Therefore, the installation position and the number of installations can be selected according to the actual use situation, for example, it can be installed at the head of the belt conveyor: installing a cleaning device at the starting end (i.e., the head) of the belt conveyor can effectively remove the residues brought by the belt from the previous process, and prevent these residues from entering the belt conveyor system and affecting the normal operation of the equipment. The tail of the belt conveyor: installing a cleaning device at the end (i.e., the tail) of the belt conveyor can remove dust, debris, etc. accumulated on the belt during transportation, ensure that the belt remains clean when returning, and reduce the wear of the return belt on the rollers and brackets. The middle part of the belt conveyor: For particularly long belt conveyors, additional cleaning devices can be installed in the middle position to clean the belt in sections, reduce the workload of a single cleaning device, and improve the overall cleaning effect. Inclined or turning sections: installing a cleaning device at the inclined or turning sections of the belt conveyor can pay special attention to the materials or dust that may accumulate in these areas, and ensure the stable operation of the belt on these complex terrains. Special working areas: According to the specific work process and material characteristics of the belt conveyor, cleaning devices can be installed in specific working areas (such as material unloading points, sorting points, etc.) to deal with the additional material residues that may be generated in these areas.

[0029] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
