Abstract
The utility model provides a cutting portion internal spraying device of a coal cutter. The cutting portion internal spraying device of the coal cutter comprises a water pipe, two groups of water seals, two groups of oil seals, bearings, bearing seats, an end cover, a rotary connector, a leakage ring and an O-shaped ring, and is characterized in that the water seals, the leakage ring, the oil seals, the bearings and the O-shaped ring are arranged in the end cover in sequence, a water pipe is inserted in the end cover in a penetrating mode, the bearings are arranged at two ends of the water pipe and are fixedly connected with the bearing seats, and one end of the water pipe is connected with the rotary connector. Assemblies are divided into two groups and are respectively arranged in a left rocker arm and a right rocker arm. The cutting portion internal spraying device of the coal cutter has the advantages that the water pipe does not rotate along with a rotary drum of the coal cutter, the service lives of the water seals and the oil seals are prolonged, the service lives of the rocker arms of the coal cutter are prolonged, and the spraying effect is improved.
Description
Technical field
The utility model relates to the cutting units inner sprayer unit of a kind of coal-winning machine, particularly a kind of coal-winning machine.
Background technology
The operating principle of coal-winning machine internal spraying is: after always water passes through main water valve, divide two strands of water to enter in the inner sprayer unit of left and right sides rocking arm, inner sprayer unit links to each other with coal-winning machine left and right sides cylinder by water pipe, internal spraying water enters behind the cylinder each nozzle ejection by cylinder, form vaporific, play the cooling depositing dust purpose.Whole inner sprayer unit is installed in the winning machine cutting part cavity.The quality of inner sprayer unit design directly has influence on the effect of coal mining machine roller spraying, and the structure major part of present inner spraying device for coal cutter all adopts two groups of water seals, one group of oil sealing, and stainless steel waterpipe, end cap, bearing support, bearing, suction ring, joint, the parts such as O shape circle form.Wherein stainless steel waterpipe is along with the rotation of coal mining machine roller, because there are a lot of impurity in the water in the mine, water pipe certainly will be to water seal in rotating for a long time, there is certain impact in the life-span of oil sealing, after oil sealing or water seal damage, the one, the effect that cylinder is sprayed can reduce greatly, and the 2nd, water can enter in the oil pocket of rocker arm of coal mining machine, cause the lubricant effect of " oil mixing with water " rocking arm greatly to reduce, have a strong impact on the application life of rocker arm of coal mining machine.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, provides a kind of novel, safety, and reliability is high, the cutting units inner sprayer unit of coal-winning machine.
The purpose of this utility model is to realize like this, comprise that water pipe, two groups of water seals, two groups of oil sealings, bearing, bearing support, end cap, swivel joint, suction ring, O shapes are enclosed, it is characterized in that: water seal, suction ring, oil sealing, bearing, O shape circle are installed in end cap successively, water pipe interts in end cap, bearing is installed at the water pipe two ends, bearing and bearing support are affixed, and the rear end of water pipe is connected with swivel joint.This assembly is divided into altogether two groups, installs respectively in the rocking arm of the left and right sides.
The utility model has the advantages that: 1, water pipe need not be followed the coal mining machine roller rotation; 2, increased the application life of water seal and oil sealing; 3, increased the application life of rocker arm of coal mining machine; 4, improved spray effect.
Description of drawings
Fig. 1 is internal construction schematic diagram of the present utility model
The specific embodiment
Below in conjunction with concrete accompanying drawing present embodiment is described further:
As shown in Figure 1,1 li of end cap water seal 2, suction ring 3, oil sealing 4, O shape circle 6 are installed successively, water pipe 7 interts in end cap, bearing is installed at the water pipe two ends, bearing 5 is installed in the front end of water pipe, bearing 8 is installed in the rear end of water pipe, and bearing 8 is affixed with bearing support 9, and the rear end of water pipe is connected with swivel joint 10.This assembly is divided into altogether two groups, installs respectively in the rocking arm of the left and right sides.
Bearing is installed at the stainless steel waterpipe two ends, bearings at both ends is played a supporting role to water pipe, joint is the spinning joint, with water pipe without matching relationship, so when drum rotating, water pipe just can and then rotate, and effectively must exempt from the damage that water seal and oil sealing cause because of wearing and tearing, thereby increased the rocking arm application life of coal-winning machine, and improved spray effect.
Claims (1)
