Description

Underground roadway ditch cleaning device

Technical Field

The utility model belongs to the technical field of coal mine equipment, concretely relates to underworkings ditch cleaning device.

Background

Coal mines, which are reasonable spaces excavated by humans when excavating geological formations rich in coal, include roadways, wells, excavation faces and the like, and can provide a large amount of coal for humans.

In the underground coal mine, in order to facilitate the discharge of sewage, drainage ditches must be arranged, common underground drainage ditches are inverted trapezoids, the trapezoid drainage ditches have the advantages of stable structure, good drainage effect and no need of frequent maintenance after construction, but after long-time use, a large amount of coal slime can be accumulated in the drainage ditches, if timely cleaning and maintenance work is not carried out, the drainage flow of the drainage ditches is influenced or even blocked, the drainage flow of the drainage ditches needs to be drained to an empty water level in the traditional manual dredging mode, the overall working efficiency is low, the labor cost is high, and most workers in the underground at present have heavy and dangerous working tasks, so that the dredging maintenance is carried out only on the bottoms of the ditches, and the side ditch walls do not carry out the cleaning work.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, provide a labour saving and time saving, can also carry out an underworkings ditch cleaning device of all-round clearance to the escape canal in the pit.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an underworkings ditch cleaning device, includes the spray gun, the sandbox, the handle, the connector, the relief valve, the spring, the sandbox lid, sand, characterized by: the sand box is characterized in that the injection gun is communicated with the sand box, one end of the injection gun is provided with a connector, the other end of the injection gun is provided with a nozzle, a pressure release valve is arranged at a position, close to the bottom, of the sand box, the pressure release valve is used for temporarily isolating the outside from the sand box under the tension of a spring, a handle is arranged on the side face of the sand box, and a sand box cover is arranged at the bottom of the sand box.

Further, the sand box cover can conveniently enter sand from the bottom.

Furthermore, the relief valve is pressed down, so that the outside and the sandbox can be communicated, and the internal air pressure is reduced.

Furthermore, the connecting port is connected with a down-hole compressed gas pipeline through a hose.

The utility model has the advantages that: the pressure difference is generated by utilizing the rapid flow of the compressed gas, so that stubborn coal slime at the bottom and the side wall of the ditch can be quickly and effectively cleaned, and time and labor are saved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model provides an underworkings ditch cleaning device, includes spray gun 1, sandbox 2, handle 3, connector 4, relief valve 5, spring 6, sandbox lid 7, sand 8, characterized by: the spray gun 1 is communicated with the sandbox 2, a connector 4 is arranged at one end of the spray gun 1, a nozzle is arranged at the other end of the spray gun, a pressure release valve 5 is arranged at a position, close to the bottom, of the sandbox 2, the pressure release valve 5 is isolated from the outside temporarily from the sandbox 2 under the tension of a spring 6, a handle 3 is arranged on the side face of the sandbox 2, and a sandbox cover 7 is arranged at the bottom of the sandbox 2.

Further, the sand box cover 7 can conveniently enter sand from the bottom.

Furthermore, the pressure relief valve 5 is pressed down, so that the outside can be communicated with the sandbox 2, and the internal air pressure is reduced.

Further, the connecting port 4 is connected with a downhole compressed gas pipeline through a hose.

During the use, be connected the connector 4 of spray gun 1 through hose 11 and compressed gas pipeline 9 in the pit, open valve 10, utilize compressed gas 12's fast flow to produce the pressure difference, extrude the inside sand 8 of sandbox 2, spray on the escape canal that needs the clearance, will adhere to the stubborn coal slime of escape canal bottom and lateral wall and clear away, after the stubborn coal slime of escape canal bottom and lateral wall is cleared up, demolish spray gun 1 and sandbox 2, clear water or compressed gas 12 clear up the mixture of the coal slime and the sand that remain in the escape canal bottom can.

When the sand 8 inside the sand box 2 is used up, the sand box cover 7 is opened to allow the sand to be added again.

In the description of this patent, it is noted that unless otherwise specifically stated or limited, the terms "mounted," "connected," and "disposed" are to be construed broadly and can include, for example, fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in this patent may be understood by those of ordinary skill in the art as appropriate.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
