The requirement of atomizing de-dusting.Currently, coalcutter largely uses the working method of cutting drum rotation coal breakage, in coal mining production process
In, necessarily lead to dust.Due to underground work narrow space, dust is unfavorable for spreading, and threatens to worker's health.
" safety regulations in coal mine " also proposed specific detail requirement for the prevention and treatment of dust, still, current institute, coalcutter manufacturing firm
The spraying device for removing dust design taken is used arranges in coal mining machine roller blade tip, head-on contacts with coal body forward direction.It is spraying
The problems such as device easily blocks, and cleaning difficulty is big, and maintenance workload is big, worker's large labor intensity.It can not achieve coalcutter internal spraying
Depositing dust does not meet " safety regulations in coal mine " about the requirement of coalcutter internal spraying normal use.Most domestic coalcutter is looked forward at present
Industry and coal mining enterprise do not solve this problem.
At present in the coal mining machine roller spraying device that multiple coal mining enterprises and coal-mine machinery manufacturing enterprise generally use, greatly
All using the spraying device arranged in drum blade and end plate radial tip, during coalcutter coal cutting, spraying device and easily
Blocking and causing by coal and dirt band is unable to atomizing de-dusting, while after spraying device blocking, and cleaning is difficult, maintenance cost is high, duty
Work large labor intensity caused internal spraying to be unable to the problem of normal use in the past for a long time.Not only violate " safety regulations in coal mine " correlation
It is required that while also influence quality standardization perfection, cause very big political honor and economic loss to enterprise.
In conclusion problem of the existing technology is:
The spraying device of existing coalcutter easily blocks, and cleaning difficulty is big, and maintenance workload is big, and worker's large labor intensity etc. is asked
Topic.It can not achieve coalcutter internal spraying depositing dust
Solve the difficulty and meaning of above-mentioned technical problem:
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of concealed reverse spray drop of coal mining machine roller
Dirt device.
The utility model is realized in this way the concealed reverse atomizing de-dusting apparatus of the coal mining machine roller includes spraying dress
It sets, the spraying device is welded on the drum blade back side, the reverse coal mining machine roller direction of rotation of the spray nozzle of the spraying device
Installation.
Further, the spraying device is provided with multiple spray nozzles, respectively reversed installation, radially installed and with radial direction
Installation at 45 °.
Further, the spraying device is mounted by means of bolts on spraying pedestal, the input terminal of the spraying device
It is connected to internal spraying water channel.
In conclusion advantages of the present invention and good effect are as follows: the concealed reverse atomizing de-dusting apparatus of the coal mining machine roller
In coalcutter work, it will thoroughly solve spraying device and easily block, cleaning difficulty is big, the big problem of maintenance workload.It realizes and mines
Machine internal spraying does not block, and exempts to clear up.It will thoroughly solve the problems, such as that inner spraying device for coal cutter is non-serviceable, internal spraying system does not block up
Plug, exempts to clear up, and atomizing de-dusting effect is good, alleviates worker's labor intensity, deep to be welcome by worker, for enterprise meet regulatory requirements and
Perfection establishes good basis.

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows to attached drawing 4 for attached drawing 1.
The concealed reverse atomizing de-dusting apparatus of the coal mining machine roller includes spraying device 1, and the spraying device 1 is welded on rolling
3 back side of cylinder blade, the reverse coal mining machine roller direction of rotation of spray nozzle 5 installation of the spraying device 1.
As the preferred embodiment of the utility model, the spraying device 1 is provided with multiple spray nozzles 5, respectively reversely
Installation, radially installed and with radial installation at 45 °.
As the preferred embodiment of the utility model, the spraying device 1 is mounted by means of bolts on spraying pedestal 4
On, the input terminal of the spraying device 1 is connected to internal spraying water channel 2.
Drum blade 3 is welded on backwards using spraying device 1 and is hidden in wear-resistant block arrangement behind (see attached drawing 1)；It is spraying
The reverse coal mining machine roller direction of rotation of spray nozzle 5 of device 1 arranges, by A on the basis of (see attached drawing 4).And this spraying device 1 has
Have following characteristics: multi-jet spray 5 is shown in that device figure (see attached drawing 2) is hidden and does not block, exempts to clear up, the spray direction and rolling of spray nozzle 5
Cylinder direction of rotation one is opposite (reverse, (A to)), radial arrangement (C to), one with radial at 45, (B to) degree angle cloth
It sets.
It can be very convenient when processing new coal mining machine roller using the concealed reverse atomizing de-dusting apparatus of the coal mining machine roller
Processing and manufacturing；It can also be transformed to coal mining machine roller, original equipment is avoided to waste, i.e., it is economical and practical.In roller leaf
The coaling top-rear side in face of piece 3 is once laterally evenly arranged, not interfere pick to dismantle for standard.Arrangement and leaf on end plate
On piece is the same, not interfere pick to dismantle for standard, is evenly arranged.Original coal mining machine roller water route is constant.Meet " coal mine
