Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and more particularly to an intelligent automatic spray device for a working face support. Background Art

[0002] In the past, the spray of the working face support was turned on manually by opening the spray cut-off valve during coal cutting to start the spray on the downwind side of the coal cutter. As the coal cutter moves, it is necessary for personnel to frequently switch the spray on and off, which is time-consuming and laborious. When the coal cutter cuts coal and retracts the first-stage rib protection plate, the rib spalling of the coal wall, the support pulling, etc. are the main sections and links for generating coal dust. It is difficult for the spray to be turned on in real time and on-site at the above-mentioned main dust-producing sections and locations of the working face, and the dust reduction effect is poor. Summary of the Invention

[0003] To make up for the above deficiencies, the present invention provides an intelligent automatic spray device for a working face support.

[0004] The embodiment of the present invention provides an intelligent automatic spray device for a working face support, including a spray liquid inlet pipe, an automatic spray control valve, a cut-off valve, a first-stage rib protection plate retraction liquid inlet pipe, a first-stage rib protection plate extension liquid inlet pipe, a spray liquid outlet pipe, and an atomizing nozzle. One end of the first-stage rib protection plate retraction liquid inlet pipe is communicated with one end of the automatic spray control valve, and one end of the first-stage rib protection plate extension liquid inlet pipe is communicated with the other end of the automatic spray control valve. A first three-way pipe is communicated with one side of the automatic spray control valve, and a second three-way pipe is communicated with the other side of the automatic spray control valve. One end of the spray liquid inlet pipe is communicated with a filter box, the bottom of the filter box is communicated with a water pump, the output end of the water pump is communicated with a delivery pipe, the other end of the delivery pipe is communicated with one end of the first three-way pipe, one end of the first three-way pipe is communicated with one end of the cut-off valve, the other end of the cut-off valve is communicated with a manual control liquid inlet pipe, the other end of the manual control liquid inlet pipe is communicated with one end of the second three-way pipe, one end of the second three-way pipe is communicated with one end of the spray liquid outlet pipe, the other end of the spray liquid outlet pipe is communicated with one end of the atomizing nozzle, and an adjusting mechanism is arranged on one side of the atomizing nozzle.

[0005] In the above implementation process, by setting the automatic spray control valve, the cut-off valve, the first three-way pipe, the second three-way pipe, and the manual control liquid inlet pipe, it is possible to facilitate manual control of the spray and automatic control of the spray, thereby realizing the integrated control of the spray; by setting the adjusting mechanism, it is possible to drive the atomizing nozzle to move and swing, thereby facilitating spray dust removal at different positions. In addition, the adjusting mechanism can drive the atomizing nozzle to swing, thereby increasing the spray range and being beneficial to improving the dust removal effect.

[0011] During the above implementation process, it is convenient to carry out control.

[0012] In a specific implementation, the adjusting mechanism includes a mounting frame. On both sides of the lower surface of the mounting frame, two groups of fixing plates are welded. A lead screw is rotatably connected between the two groups of fixing plates. On the outer surface of one group of fixing plates, a first servo motor is fixedly arranged. The output end of the first servo motor is in transmission connection with one end of the lead screw. An adjusting block is threadedly connected to the circumference of the lead screw. A double-pass connection seat is fixedly arranged on the lower surface of the adjusting block. One end of the spray liquid inlet pipe is communicated with the atomizing nozzle through the double-pass connection seat. The atomizing nozzle is connected to the lower surface of the double-pass connection seat through a rotating assembly.

[0013] During the above implementation process, the first servo motor drives the lead screw to rotate, the lead screw drives the adjusting block to move, the adjusting block drives the double-pass connection seat to move, and the double-pass connection seat drives the atomizing nozzle to move, so as to conveniently adjust the position of the atomizing nozzle and facilitate dust removal at different positions.

[0014] In a specific implementation, mounting blocks are welded around the outer surface of the mounting frame, and reserved mounting holes are provided on the mounting blocks.

[0015] During the above implementation process, it is convenient to disassemble and assemble the mounting frame.

[0016] In a specific implementation, a guide rod is welded between the two groups of mounting frames. The guide rod penetrates through the adjusting block and is slidably connected to the adjusting block.
