[0028] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0029] Embodiment 1:

[0030] A scraper cleaning device for efficient cleaning comprises a cleaning motor 1, wherein the output end of the cleaning motor 1 is connected to a cleaning roller 2, the cleaning roller 2 is connected to an adjusting bracket 12, a plurality of cleaning scrapers 5 are arranged on the cleaning roller 2, the plurality of cleaning scrapers 5 are evenly divided into a plurality of groups, each group of cleaning scrapers 5 are sequentially arranged on the outer wall of the cleaning roller 2, each group of cleaning scrapers 5 are arranged in a herringbone shape around the cleaning roller 2, one end of each cleaning scraper 5 is threadedly connected to a knife groove 6, and each knife groove 6 is arranged on the outer surface of the cleaning roller 2.

[0031] When it is necessary to clean the frozen and sticky materials on the conveyor belt in winter, the coal powder and sticky materials on the return journey, adjust the position of the cleaning scraper 5 and the conveyor belt, start the cleaning motor 1 to drive the cleaning roller 2 to rotate, and then drive the cleaning scraper 5 to clean the materials on the surface of the conveyor belt at one time. The cleaning scrapers 5 are arranged in multiple rows in a herringbone shape, and can start to crush the surrounding frozen and sticky materials from multiple points at the same time, and can remove all the sticky materials on the conveyor belt at one time, which improves the efficiency of the cleaning work. Integrate the spiral scraper cleaning machine into the electrical cabinet or PLC control of the belt conveyor equipment, install 4KW overload and missing item protection, and start it at the same time as the conveyor belt equipment, and never start it later than the conveyor belt equipment.

[0032] It should be noted that the material of the cleaning scraper 5 in the present application is a rubber composite material, which has excellent wear resistance and elasticity. When the cleaning scraper 5 cleans frozen materials and coal powder, it can avoid damage to the belt and increase the service life of the belt. The scraper cleaning machine has a unique and simple structure, is easy to install and adjust on site, and is easy to maintain with a small maintenance workload.

[0033] Two threaded holes 7 are symmetrically provided on each knife groove 6, and a connection hole 8 used in conjunction with the threaded hole 7 is provided at one end of the cleaning scraper 5 connected to the knife groove 6. A fixing adjustment bolt 11 is threadedly connected to each knife groove 6, and the fixing adjustment bolt 11 is provided through the connection hole 8 and the two threaded holes 7. Through the above technical solution, when the cleaning scraper 5 needs to be replaced separately, the fixing adjustment bolt 11 can be disassembled, taken out from the connection hole 8 and the threaded hole 7, and a new cleaning scraper 5 is replaced and then fixed by the fixing adjustment bolt 11, thereby completing the maintenance and replacement. Compared with a whole row of scrapers connected to the same knife groove 6, the cleaning scraper 5 is fixed by using a separate knife groove 6, which can be easily replaced, is simple to operate, and can also reduce production costs.

[0034] The cleaning roller 2 is provided with a sleeve 4, and the cleaning scraper 5 is arranged on the outer wall of the sleeve 4 through a knife groove 6. The cleaning roller 2 is provided with a main shaft 3, and the main shaft 3 is fixedly connected to the output end of the cleaning motor 1. The knife groove 6 is welded to the outer wall of the sleeve 4, which can improve the stability of the knife groove 6. In the process of the cleaning scraper 5 cleaning the conveyor belt, it is ensured that the knife groove 6 will not move, and the cleaning efficiency can also be ensured.

[0035] It also includes an adjustment bracket 12, on which two transverse grooves 9 are symmetrically provided, and roller mounting seats 10 are connected to both ends of the main shaft 3, and each roller mounting seat is connected to the corresponding transverse groove 9. When the material thickness at some positions on the conveyor belt is relatively thick, the sliding roller mounting seat 10 moves in the transverse groove 9, driving the main shaft 3 and the sleeve 4 to move, and then adjusting the position of the cleaning scraper 5 and the conveyor belt, thereby ensuring that the conveyor belt can be cleaned at one time even when the frozen and sticky material is relatively thick, thereby improving the flexibility of the cleaning machine.

[0036] For a bidirectional belt, the angle of the cleaning scraper 5 can be adjusted to achieve the same cleaning effect.

[0037] Embodiment 2:

[0038] Except for the following features, the remaining features are the same as those described in Example 1.

[0039] like Figure 3-5 As shown, each group of cleaning scrapers 5 can also be arranged in a spiral shape around the cleaning roller 2. At this time, the cleaning scrapers 5 that are in contact with the conveyor belt at different angles can break the frozen sticky materials into small pieces and remove them from the conveyor belt. The cleaning scrapers 5 arranged in a spiral shape can improve the cleaning effect, so that all the sticky materials on the conveyor belt can be removed at one time, thereby improving work efficiency.

[0040] The installation position of the cleaning roller 2 in the embodiment 1 and the present embodiment is located at the starting point of the return conveyor belt, and the closer to the throwing roller the better. Figure 2 The characteristics of the cleaning scraper 5 are determined according to the specific conditions on site, such as height and hardness, as well as the linear speed of the roller, to ensure full coverage to achieve user satisfaction.

[0041] It is obvious 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 features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
