Description
Technical Field
The utility model relates to the field of dairy product production dust removal, in particular to a dustproof coal cutter drum cutting head.
Background
The coal mining machine is one of important devices for realizing mechanization and modernization of coal mine production. The mechanized coal mining can reduce the physical labor, improve the safety and achieve the purposes of high yield, high efficiency and low consumption. When coal mining machine during operation among the prior art, the cutterhead on the drum cutterhead subassembly can produce a large amount of dust pollution when cutting coal seam or rock, in order to reduce the pollution of dust, need set up atomizer on the rocking arm of drum cutterhead and carry out the dust fall, but dust fall device is fixed dead, and the concentration of different coal seam mining dust is also different, can not be fine adaptation when meetting the great dust of concentration, lead to the cutterhead visibility relatively poor, the efficiency of exploitation has been reduced, and the environment of exploitation has still been reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problems, the utility model provides a dustproof shearer drum cutting head.
The utility model is realized by the following technical scheme:
the utility model provides a coal-winning machine cylinder cutterhead with dirt-proof, includes the cylinder cutterhead of constituteing by rocking arm and the cutting drum of front end lateral part swivelling joint, set up the dust removal mechanism that can adjust from beginning to end on the rocking arm, dust removal mechanism is including the bar frame of cover on the rocking arm, the outside of bar frame is fixed with the dust removal spray pipe, the dust removal spray pipe just installs a plurality of nozzles to the cutting drum region.
Preferably, be fixed with the fixture block that sets up in the spout on the both sides inner wall of bar frame, the spout sets up on the both sides face of rocking arm, the inside bottom of spout evenly is provided with a plurality of latch, open the bottom of fixture block has a plurality of draw-in grooves that match with the latch.
Preferably, the distance between the upper part of the clamping block and the sliding groove and the distance between the bottom end of the strip-shaped frame and the rocker arm are not less than the height of the clamping teeth.
Preferably, a water conveying pipe connected with the dust removal spraying pipe is arranged on the outer side of the rocker arm.
Compared with the prior art, the utility model has the beneficial effects that: this practicality makes the nozzle adaptability of dust removal spray tube better through set up the dust removal mechanism that can adjust on the rocking arm of coal-winning machine cutterhead, has improved the effect of dust fall and the visibility around the cutting drum, guarantees the exploitation efficiency of coal-winning machine, has still improved operational environment moreover.
Drawings
FIG. 1 is a schematic view of the structure of the present invention;
FIG. 2 is a perspective view of a partial structure of the rocker arm of the present invention;
FIG. 3 is another perspective view of FIG. 2;
in the figure: the device comprises a rocker arm 1, a cutting drum 2, a dust removing mechanism 3, a sliding groove 4, a latch 5, a fixture block 6, a strip-shaped frame 7, a dust removing spray pipe 8, a nozzle 9 and a water delivery pipe 10.
Detailed Description
The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, 2 and 3, the dustproof shearer drum cutter head comprises a drum cutter head composed of a rocker arm 1 and a cutter drum 2 rotationally connected with the front end side part of the rocker arm 1, wherein a dust removing mechanism 3 capable of being adjusted forwards and backwards is arranged on the rocker arm 1, the dust removing mechanism 3 comprises a strip-shaped frame 7 sleeved on the rocker arm 1, a dust removing spray pipe 8 is fixed on the outer side of the strip-shaped frame 7, and a plurality of nozzles 9 are installed on the dust removing spray pipe 8 and just face the area of the cutter drum 2.
Be fixed with the fixture block 6 that sets up in spout 4 on the both sides inner wall of bar frame 7, spout 4 sets up on the both sides face of rocking arm 1, the inside bottom of spout 4 evenly is provided with a plurality of latch 5, open the bottom of fixture block 6 has a plurality of draw-in grooves that match with latch 5.
The distance between the upper part of the clamping block 6 and the sliding groove 4 and the distance between the bottom end of the strip-shaped frame 7 and the rocker arm 1 are not lower than the height of the clamping teeth 5.
And a water delivery pipe 10 connected with the dust removal spray pipe 8 is arranged on the outer side of the rocker arm 1.
The working principle is as follows: when the dust-settling device is used, the cutting drum 2 at the front end of the rocker arm 1 of the cutting head of the coal mining machine rotates to mine a coal bed, more dust is generated in the mining process, meanwhile, the control valve on the water pipe 10 is opened, and high-pressure water enters the dust-settling spray pipe 8 and is sprayed out along the nozzle 9, so that dust-settling treatment is realized around the cutting drum 2;
when the coal seam is soft and produces large dust, the strip-shaped frame 7 on the rocker arm 1 can be lifted to enable the clamping groove of the clamping block 6 to be separated from the clamping tooth 5, and the clamping block 6 is moved forwards along the sliding groove 4 of the rocker arm 1, so that the dedusting spraying pipe 8 is moved forwards through the strip-shaped frame 7, the spraying distance of the nozzle 9 of the dedusting spraying pipe 8 is shortened, the spraying strength of the nozzle 9 is improved, the dedusting effect and the visibility around the cutting drum 2 are improved, the mining efficiency of a coal mining machine is ensured, and the working environment is also improved; after the position is adjusted, the clamping block 6 is clamped on the clamping teeth 5 of the sliding groove 4, so that the dust removal spraying pipe 8 is positioned.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
