[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1, reference Figure 1-3 , which is the first embodiment of the present invention, provides an automatic coal scraping device at the tail of a coal mine belt conveyor, the device includes a coal transport unit 100, including a support base 101, which serves as the basis of the entire device and is used to support and fix a transport part 102 and a sorting part 103. The transport part 102 arranged on the support base 101 is responsible for transporting the coal, and the sorting part 103 arranged downstream of the transport part 102 is used to sort the coal.

[0031] The coal accumulation removal unit 200 includes a scraper 201 disposed on the support base 101 for scraping off the coal accumulation at the tail of the conveyor belt, and a removal part 202 disposed on the scraper 201 for cleaning the coal accumulation on the transport part 102 .

[0032] The transport unit 102 includes a transport component 102a disposed on the support base 101 for transporting coal, and a power component 102b disposed beside the support base 101 for providing a power source to reduce the labor intensity of the staff.

[0033] During use, the staff dumps the coal on the transport part 102, and the power component 102b drives the transport component 102a to move the coal to the sorting part 103. The large pieces of coal enter the next operation link, and the small broken pieces of coal are moved to the scraper 201 with the transport component 102a to be removed, and further cleaned in the cleaning part 202 to avoid accumulation and deposition on the transport part 102, which reduces work efficiency. The device can effectively remove coal powder and coal blocks at the tail of the conveyor belt, reduce resource waste, reduce equipment wear, and improve the efficiency and safety of coal mine operations.

[0034] Example 2, reference Figure 1-6, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the transportation component 102a includes a conveyor belt 102a-1 arranged on a supporting base 101, baffles 102a-2 arranged on both sides of the conveyor belt 102a-1 to prevent coal from overflowing or scattering outside the conveyor belt 102a-1 during transportation, thereby reducing the scattering and loss of coal, and a guide plate 102a-3 arranged at the head of the conveyor belt 102a-1 to guide the coal to smoothly enter the conveyor belt 102a-1, thereby ensuring smooth flow of coal, reducing flying coal dust, and reducing pollution to the mining environment. Through the design of the guide plate 102a-3, the coal can be more effectively introduced into the conveyor belt 102a-1, which helps to reduce coal splashing and protect equipment and personnel from damage.

[0035] Compared with Example 1, further, the power component 102b includes a protective shell 102b-1 arranged next to the support base 101, which helps to extend the service life of the motor 102b-2 and the roller 102b-3 and reduce maintenance requirements. The motor 102b-2 arranged inside the protective shell 102b-1 is responsible for driving the roller 102b-3 to rotate. The roller 102b-3 connected to the motor 102b-2 and the roller 102b-4 connected to the roller 102b-3 through a belt support the conveyor belt 102a-1 and reduce friction and wear during its operation. The protective shell 102b-1 can prevent the motor 102b-2 and the roller 102b-3 from being affected by environmental factors such as coal dust and moisture, reduce the failure rate, thereby reducing maintenance costs, and can also prevent operators from directly contacting moving parts, reducing the risk of accidental injury.

[0036] Compared with Example 1, further, the sorting section 103 includes a collecting component 103a arranged downstream of the conveyor belt 102a-1, which is arranged downstream of the conveyor belt 102a-1 and is mainly responsible for collecting the coal after being screened from the sorting section 103, and a diversion component 103b arranged on the collecting component 103a, which can further divert the collected coal to different processing paths. Through the coordinated work of the collecting component 103a and the diversion component 103b, the coal can be sorted more efficiently, thereby improving the efficiency of the entire conveying system. Accurate sorting can reduce the loss of high-quality coal and improve the utilization rate of resources, while also reducing manual intervention and reducing the safety risks of operators during the sorting process.

[0037] Compared with Example 1, further, the collecting component 103a includes a collecting chamber 103a-1 arranged downstream of the conveyor belt 102a-1, for collecting the coal screened from the sorting section 103, and a partition 103a-2 arranged inside the collecting chamber 103a-1, for separating coal of different types or sizes, and performing preliminary classification of the coal, so that the subsequent diversion and processing process is more efficient and orderly, and the complexity and cost of subsequent processing are reduced.

[0038] Compared with Example 1, further, the diversion component 103b includes a support plate 103b-1 arranged on the collecting chamber 103a-1, and a blower 103b-2 arranged on the support plate 103b-1. The support plate 103b-1 fixes the blower 103b-2 at a suitable height, provides a stable installation platform for the blower 103b-2, and ensures the stability and reliability of the diversion operation. The wind force generated by the blower 103b-2 is used to further divert the collected coal, and blow the coal to different processing areas or collection points according to the weight and size of the coal, while reducing the breakage of the coal and the wear of the equipment, thereby improving the accuracy and efficiency of the sorting.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3, reference Figure 1-6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the cleaning part 202 includes a clamping component 202a arranged on the scraper 201, and a cleaning component 202b arranged on the clamping component 202a. The clamping component 202a provides necessary pressure for the scraper 201 to ensure that the scraper 201 can fit tightly on the surface of the conveyor belt, thereby effectively scraping off the accumulated coal. Through the coordinated work of the clamping component 202a and the cleaning component 202b, the accumulated coal on the surface of the conveyor belt can be more effectively removed, reducing manual intervention and improving the level of automation.

[0041] Compared with Example 2, further, the clamping assembly 202a includes a clamping spring 202a-1 arranged on the scraper 201, and a roller 202a-2 arranged on the clamping spring 202a-1. The clamping spring 202a-1 ensures that the scraper 201 can fit tightly against the surface of the conveyor belt, thereby effectively scraping off the accumulated coal. The scraper 201 automatically adjusts the pressure according to the tension of the conveyor belt, so that the scraper 201 can adapt to the cleaning requirements under different working conditions. The roller 202a-2 is arranged on the clamping spring 202a-1, and can roll when the scraper 201 contacts the conveyor belt, thereby reducing friction and wear, and improving the service life and cleaning efficiency of the scraper 201. It can also reduce the impact force when encountering an uneven clamping surface, thereby reducing the impact and vibration on the equipment as a whole.

[0042] Compared with Example 2, further, the cleaning component 202b includes a spray head 202b-1 arranged on the roller 202a-2, and a fan 202b-2 arranged on the spray head 202b-1. The spray head 202b-1 is arranged on the roller 202a-2, and is used to spray cleaning liquid or water onto the surface of the conveyor belt to assist in removing the accumulated coal, reduce the adhesion of the accumulated coal to the conveyor belt, and reduce the friction and wear during the coal cleaning process. The fan 202b-2 helps to blow away the accumulated coal, improve the cleaning efficiency, and further clean the fine particles on the surface of the conveyor belt to ensure that the accumulated coal is completely removed, while also reducing the physical damage to the conveyor belt. The combined use of the spray head 202b-1 and the fan 202b-2 can more effectively remove the accumulated coal on the surface of the conveyor belt, reduce manual intervention, improve the level of automation, reduce the direct friction between the scraper 201 and the conveyor belt, and extend the service life of the scraper 201.

[0043] The remaining structure is the same as that of Example 2.
