[0023] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0024] When mining and transporting water-bearing coal in cold regions, the conveyor belt may become frozen and stuck. This utility model is used to clean frozen and stuck conveyor belts. The striking member on the cleaner repeatedly strikes the conveyor belt to remove frozen and stuck impurities. The striking member is made of elastic material, so the striking will not damage the conveyor belt.

[0025] refer to Figures 1 to 3As shown, a conveyor belt frozen sticky material cleaner includes a motor 1, a reducer 2 and a transmission rod 3. The motor 1 and the reducer 2 drive the transmission rod 3 to rotate to drive the cleaner. A gear rod 301 is installed on the transmission rod 3. The length of the gear rod 301 can be adapted according to the site. The conveyor belt to be cleaned can be placed below or above the gear rod 301. It is installed at the turning point of the conveyor belt so that the broken frozen sticky materials can be dumped down as the conveyor belt turns to complete the cleaning.

[0026] refer to Figures 3 to 4 As shown, a striking member 4 is installed on the gear rod 301, and the striking member 4 includes a fixing ring 401, a connecting key 402, a striking part 403 and a gear 404. The striking member 4 is integrally formed. The integrally formed manufacturing can enhance the strength of the striking member, reduce the tearing phenomenon during the striking of the conveyor belt, and avoid complicated installation steps.

[0027] The striking member 4 is made of an elastic material, such as rubber. When striking the conveyor belt, the striking member 4 does not damage the conveyor belt itself. Common coal mine conveyor belts are rubber conveyor belts. Using hard metal or the like to strike the conveyor belt may damage the frozen conveyor belt. The striking portion 403 is a block-shaped structure. The sharp corners on the striking portion 403 serve as striking contact points, which can reduce the contact area and increase the striking effect. However, because the striking member 4 is made of an elastic material, it is susceptible to wear and tear during repeated striking. If the sharp corners on one side of the striking portion 403 become worn, the striking member 4 can be disassembled and inverted onto the gear rod 301 or the motor 1 can be reversed, allowing the unworn side of the striking portion 403 to perform the striking work. This extends the service life of the striking member and reduces costs.

[0028] refer to Figures 3 to 4 As shown, the length of the connecting key 402 is greater than the length of the striking portion 403, so that the deformation caused by the striking portion 403 is sufficiently released. If the connecting key 402 is too short, the deformation of the striking portion 403 during the striking can easily cause the connecting key 402 to tear. Moreover, a longer connecting key 402 can increase the efficiency of ejecting frozen sticky objects that are struck and entangled in multiple striking members 4. The connection between the connecting key 402, the striking portion 403 and the fixing ring 401 is provided with rounded corners to prevent tearing during the striking process of the striking portion 403, thereby enhancing the service life and stability of the striking member 4 as a whole.

[0029] A fixed ring 401 is sleeved onto the gear rod 301. The fixed ring 401 is provided with a gear 404 that cooperates with the gear rod 301, and the rotation of the gear rod 301 causes the striking member 4 to be synchronously displaced. The number of striking members 4 installed on the gear rod 301 is adjustable, and the number of striking members 4 on the gear rod 301 can be allocated according to the width of the conveyor belt on site and the frozen sticking situation, thereby avoiding the situation where insufficient striking force is generated and the conveyor belt cannot be cleared. The mounting angle of the striking members 4 installed on the gear rod 301 is adjustable. In this embodiment, there are eight striking parts 403 on the striking members 4, and the angle between the striking parts 403 is 45 degrees. The angle between the striking parts 4 installed on the striking parts 403 can be allocated according to the frozen sticking situation of the conveyor belt on site. The smaller the angle, the more dense the installation, the better the cleaning effect. However, it should be noted that too dense an installation of striking members 4 may cause the frozen sticking objects caught in the striking members 4 to be ejected in an inefficient manner.

[0030] refer to Figures 3 to 5 As shown, a blocking member 5 is installed on the gear rod 301. The number of blocking members 5 installed on the gear rod 301 is adjustable. The blocking member 5 is used to separate the striking member 4 on the gear rod 301. When the on-site situation does not require a large number of striking members 4 or frozen sticky objects are stuck in multiple striking members 4, the blocking member 5 can be installed according to the on-site situation to increase the spacing between the striking members 4 to reduce the stuck situation of frozen sticky objects.

[0031] refer to Figures 4 to 5 As shown, a removable protective cover 405 is attached to the striking member 403. The protective cover 405 is made of an elastic material. The protective cover 405 is used to reduce wear on the striking member 403. Furthermore, when attached to a worn striking member 403, it allows the striking member 4 to continue functioning, extending the lifespan of the striking member 4 and reducing replacement costs. The curved surface of the protective cover 405 where it strikes the conveyor belt effectively reduces wear. Furthermore, the curved surface allows it to be attached to the exterior of a worn striking member 403, allowing continued use.

[0032] During specific use, a customized number of striking members 4 and blocking members 5 can be installed according to the on-site usage scenario, and the spacing angle of the striking members 4 can be adjusted during installation. The frozen conveyor belt to be cleaned is placed above or below the cleaner, and the motor 1 and reducer 2 are started. The motor 1 and reducer 2 drive the transmission rod 3 to rotate synchronously, and the transmission rod 3 drives the gear rod 301 installed thereon and the striking members 4 installed on the gear rod 301 to rotate.

[0033] The striking member 4, mounted on the gear rod 301, regularly cycles to strike the frozen conveyor belt above or below it. The striking member 4 is made of an integrally formed elastic material, which does not damage the rubber conveyor belts commonly used in coal mining during the striking process. Furthermore, the elastic material of the striking member 4 reduces stress during the striking, thereby increasing its service life. The striking member 4 strikes the corners of the striking portion 403. Elastic materials such as plastic can wear out during use. In this case, the striking member 4 can be reversed or the motor 1 can be rotated to allow the unworn corners of the striking portion 403 to strike the frozen conveyor belt.

[0034] The striking part 403 on the striking member 4 can be covered with a protective cover 405 on the outside. The protective cover 405 is also made of elastic material. The covered protective cover 405 can protect the striking part 403 inside it and prevent it from wear. At the same time, the protective cover 405 is arc-shaped and can be directly covered on the striking part 403 that has been worn, so that it can continue to work and extend the service life of the striking member 4.

[0035] When the striking member 4 hits the conveyor belt, the broken frozen sticky matter on it may be caught between the densely installed striking members 4. At this time, the number of striking members 4 can be reduced according to the on-site conditions, or an appropriate number of blocking members 5 can be installed between the striking members 4 to allow the broken frozen sticky matter to have enough space to be thrown out.

[0036] Compared with the prior art, the beneficial effect of the present invention is that a sweeper with an elastic striking part is installed on the frozen conveyor belt, and the ice on the surface of the conveyor belt is cleaned by cyclically and intensively striking the conveyor belt, and the striking will not damage the conveyor belt itself.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
