Abstract
A spray device externally connected to the rocker arm of a roller coal excavator is divided into one long seamless steel pipe. The two ends of the seamless steel pipe are sealed. The seamless steel pipe is connected to the bent part of the rocker arm of a roller coal excavator. At least two nozzles are uniformly arranged on the seamless steel pipe, and a joint used for connecting water pipes and a connecting component used for installation are welded on the bottom of the seamless steel pipe. The spray device is arranged on the bent part of the rocker arm of the roller coal excavator. After the spray device is connected with water, the water is sprayed out from the nozzles, and a water curtain is formed on the work plane of coal excavation for preventing dust from spreading. The spray device externally connected to the rocker arm of a roller coal excavator stays closer to places producing coal dust, so the spray quantity is largely increased than that of original spray devices. In addition, spray angles can be adjusted during the work, dust reducing areas are increased, and dust reducing effect is largely improved.
Description
Technical field
The utility model relates to the external atomization mechanism of a kind of flitting rocking arm, is suitable for coal mine fully-mechanized mining face, general flitting atomizing de-dusting use when mining of adopting face, comprehensive coal face.
Background technology
At present, dust still is one of subject matter of puzzlement Coal Production.The dust of high concentration has caused serious threat to the colliery safety in production, and especially expiration property dust is the immediate cause of bringing out coal miner point tuberculosis.Therefore, the concentration that reduces dust concentration, particularly respirable dust is very necessary, also is a major technology difficult problem.
Now the coal-winning machine that uses all is equipped with the atomization mechanism that is used for depositing dust, but one be far away apart from the cylinder operating point, and the 2nd, atomization mechanism is too little, and two shower nozzles are only arranged, and does not almost have the effect of depositing dust.The coal miner works under such condition, not only reduce production efficiency, increased the probability that various industrial accidents take place, but also hidden the possibility that coal-dust explosion takes place in the hiding, threaten the safety in production under the coal mine, simultaneously also to stopping the healthy very unfavorable of coal workman.
Summary of the invention
The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of dust-laying effect the good external atomization mechanism of flitting rocking arm.
The external atomization mechanism of flitting rocking arm of the present utility model is made of a microscler seamless steel pipe, the closed at both ends of seamless steel pipe, be connected crook on the rocking arm of flitting, on seamless steel pipe, evenly be provided with and be no less than 2 nozzle, and be welded with the joint that is used to connect water pipe in the bottom of seamless steel pipe, also be provided with a connector in seamless steel pipe top connection one side.
Wherein, described nozzle is positioned on the seamless steel pipe on the radially same straight line.
The external atomization mechanism of flitting rocking arm of the present utility model can also be according to the model difference of coal-winning machine, carry out up and down direction and angle initialization, reach the optimum efficiency of atomization mechanism, therefore, the utlity model has compliance widely, can improve the working environment under the coal mine effectively.
The cutting coal dust that coal produced can play tangible dust-laying effect when the external atomization mechanism of flitting rocking arm of the present utility model was worked for coal-winning machine, compare with original atomization mechanism, the external atomization mechanism one of flitting rocking arm of the present utility model is that the root point of distance generation coal dust is nearer, the 2nd, spray amount is than originally strengthening greatly, and can adjust spray angle at work, increase the depositing dust area, greatly improved dust-laying effect.
Description of drawings
Fig. 1 is the structural representation of the external atomization mechanism of the utility model flitting rocking arm.
The specific embodiment
The structure of the external atomization mechanism of flitting rocking arm as shown in Figure 1, seamless steel pipe 1 by a long 380mm, diameter 60mm is made. with the closed at both ends of seamless steel pipe 1, wherein an end welds a joint 3 and a connector 4, and the atomization mechanism of making is installed in by connector 4 near crook on the rocker arm of coal mining machine of cylinder work at the nozzle 2. that is provided with a plurality of M20 on the radially same straight line on the steel pipe, its joint 3 connects water pipe, in device, feed press water, then press water sprays from nozzle 2, form water curtain at coal-face, stop the dust diffusion.
After tested, compare with traditional coal miner spray, this atomization mechanism can improve dust reduction rate more than 70%.
Claims (3)
1. the external atomization mechanism of flitting rocking arm, be connected crook on the rocking arm of flitting, it is characterized in that constituting by the seamless steel pipe (1) of a microscler closed at both ends, evenly be provided with the nozzle (2) that is no less than 2 above, be welded with the joint (3) that is used to connect water pipe in the bottom of seamless steel pipe (1).
