Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, and in particular to a coal mine transportation equipment for underground mining. Background Technology

[0002] In underground coal mining operations, coal transportation is a crucial link in ensuring smooth production. Currently, wheelbarrows are a common type of coal transportation equipment widely used. To effectively suppress dust generated during coal transportation and reduce the harm of dust to the underground working environment and workers' health, spray devices are usually installed on the wheelbarrows.

[0003] However, the existing dust suppression method using spraying has shortcomings. After suppressing the dust, most of the water used for spraying flows to the ground. The underground working space in coal mines is relatively narrow, and the ground conditions are complex; the large amount of water accumulation makes the ground slippery. This greatly affects the safety and ease of operation for workers pushing carts. Workers need to expend more effort to maintain balance and prevent the carts from slipping on the wet ground, increasing labor intensity and significantly raising the risk of accidents. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the above-mentioned problems with coal mine transportation equipment used in underground coal mining, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a coal mine transportation equipment for underground coal mining, including a trolley with a spraying function, the trolley having two wheels, a drainage pipe running through the bottom wall of the trolley, and two symmetrically distributed branch pipes connected to the end side of the drainage pipe, with a drainage area for dripping wastewater formed below the opening end of each branch pipe;

[0007] Each of the wheels is equipped with a bevel gear 1. The bottom of the trolley is rotatably equipped with two drive shafts that axially pass through the water area. Each of the two drive shafts is fixedly fitted with a bevel gear 2 that meshes with the corresponding bevel gear 1. Each drive shaft is also fixed with an impeller located in the water area. The impeller rotates within the water area under the control of the wheel rotation to form a scattering section.

[0008] In a preferred embodiment of the coal transportation equipment for underground coal mining described in this utility model, the width of the blades on the impeller is 1.5 to 2 times the diameter of the diversion pipe.

[0009] As a preferred embodiment of the coal mine transportation equipment for underground mining described in this utility model, the bottom inner wall of the trolley is inclined, and the connection between the drainage pipe and the trolley is located at the center of the bottom edge of the inclined surface.

[0010] As a preferred embodiment of the coal mine transportation equipment for underground mining described in this utility model, the connection between the diversion pipe and the trolley is a funnel structure, and the body of the diversion pipe is inclined.

[0011] As a preferred embodiment of the coal mine transportation equipment for underground mining described in this utility model, a filter screen is provided inside the funnel structure on the diversion pipe.

[0012] The beneficial effects of this invention are as follows: The drainage pipe guides the wastewater generated during the cart-based spraying process. As the wastewater drips downwards, it is dispersed by the impeller that rotates synchronously with the cart's movement, resulting in even distribution of the wastewater on both sides of the road. This effectively avoids road flooding caused by concentrated wastewater discharge, significantly improving road dryness and safety. It also allows workers to move vehicles more smoothly during coal mine transportation, eliminating concerns about wheel slippage and slow travel caused by water accumulation, thus significantly improving coal mine transportation efficiency.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0023] Reference Figures 1-4 This invention provides a coal mine transportation device for underground coal mining, which includes a trolley 1 with a spraying function. The trolley 1 has two wheels 11. A drainage pipe 2 is provided through the bottom wall of the trolley 1. Two symmetrically distributed diversion pipes 21 are connected to the side of the end of the drainage pipe 2. A drainage area for dripping wastewater is formed below the opening end of each diversion pipe 21. The end of the diversion pipe 21 extends outward from the trolley 1, so that the drainage area is close to both sides of the road.

[0024] Each wheel 11 is equipped with a bevel gear 3 on its axle. The bottom of the trolley 1 is equipped with two drive shafts 4 that axially pass through the drainage area. Each drive shaft 4 is fixedly fitted with a bevel gear 5 that meshes with the corresponding bevel gear 3. Each drive shaft 4 is also fixed with an impeller 6 located in the drainage area. The width of the blades on the impeller 6 is 1.5 to 2 times the diameter of the diversion pipe 21. Through the meshing of the bevel gear 3 and the bevel gear 5, when the wheel 11 rotates, the drive shaft 4 drives the impeller 6 to rotate synchronously. The impeller 6 rotates in the drainage area to form a dispersing section. When the wastewater enters the dispersing section from the drainage area, the wastewater is dissipated by the impeller 6, so that it is evenly distributed on both sides of the road and avoids water accumulation in the center of the road.

[0025] like Figure 2 and Figure 3 As shown, the bottom inner wall of the cart 1 is inclined, and the connection between the drainage pipe 2 and the cart 1 is located in the middle of the bottom edge of the inclined surface. The connection between the drainage pipe 2 and the cart 1 is a funnel structure. A filter screen 22 is installed in the funnel structure on the drainage pipe 2 to filter solid particles in the wastewater, prevent the drainage pipe 2 and the diversion pipe 21 from clogging, extend the service life of the equipment, and reduce maintenance costs. In addition, the body of the drainage pipe 2 is inclined, which makes it easier for the wastewater to flow downward.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
