The mine pneumatic saw comprises a machine frame which is provided with a transmission case, a pneumatic motor, and a tool rest which is provided with a cutting saw blade; one end of the tool rest is hinged with the transmission case; the cutting saw blade is connected with the tool rest through a sliding block to ensure that that the cutting saw blade can do reciprocating motion on the tool rest; a reduction gear and a drive gear which are meshed with each other are arranged in the transmission case; the drive gear is in key connection with an output shaft of the pneumatic motor; the reduction gear is provided with an eccentric hole; a connection rod I is hinged between the eccentric hole and the cutting saw blade; the surface of the reduction gear, which is opposite to the eccentric hole is provided with a travel block; the travel block is contacted with a travel switch which controls an air cylinder positioned on one side of the reduction gear to lift; a piston rod of the air cylinder is hinged with a connection rod II; and the other end of the connection rod II is hinged with the tool rest. The mine pneumatic saw is high in reliability, stable in performance, and high in practical value, and is convenient to use and maintain.
Description
Technical field
The utility model relates to the Metal Cutting apparatus field, is specifically related to a kind of mining wind saw.
Background technology
Metal materials such as the scraper conveyer chain in colliery crackle occurs easily because high load capacity carries, because of production safety needs to change as early as possible.Mining saw is a kind of mining instrument that is used for cutting the metal materials such as chain that have crackle under the coal mine, with convenient replacing to materials such as chains.From reasons such as gas safeties, electric saw does not generally advise adopting.The type of existing mining hard iron is manual hard iron and hydraulic pressure hard iron, and its weak point is: 1. common manual hard iron is wasted time and energy, and efficient is extremely low, has greatly influenced Coal Production efficient.2. though hydraulic pressure hard iron power is big, speed is also regulated easily, because there are drawbacks such as complex structure, part processing precision requirement height, maintenance difficult in hydraulic system, defines its scope of application.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of stable performance, cutting efficiency mining wind high, that the scope of application is wide to saw.
A kind of mining wind saw comprises frame, and said frame is provided with transmission case, air motor and the knife rest of cutting saw blade is installed; Said knife rest one end is hinged on the transmission case, and said cutting saw blade is implemented in moving back and forth on the knife rest through the slide block connection, is provided with the reduction gearing and the driving gear that are meshed in the said transmission case; Driving gear key is connected on the output shaft of air motor; Said reduction gearing is provided with eccentric orfice, and connecting rod I is hinged between this eccentric orfice and the cutting saw blade, and the corresponding surface of said reduction gearing and eccentric orfice is provided with the stroke piece; The trip piece touches and is provided with travel switch; The cylinder that said travel switch control is positioned at reduction gearing one side goes up and down, and the piston rod of this cylinder and connecting rod II are hinged, and the said connecting rod II other end is hinged on the knife rest.
Also be provided with the gear on-off of control cutting speed and position in the said transmission case.
The utility model adopts air motor as power source, realizes the various motions of cutter through machine driven system, and reliability is high, can maximum protection cutter, and stable performance is used easy to maintenancely, has bigger practical value.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is further specified.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
Embodiment 1
Referring to Fig. 1, a kind of mining wind saw that the utility model provides comprises frame 1; Said frame 1 is provided with transmission case 2, air motor 3 and the knife rest 5 of cutting saw blade 4 is installed, and said knife rest 5 one ends are hinged on the transmission case 2, and said cutting saw blade 4 is implemented in moving back and forth on the knife rest 5 through slide block 4a connection; Be provided with the reduction gearing 2a and the driving gear 2b that are meshed in the said transmission case 2, driving gear 2b key is connected on the output shaft of air motor 3, referring to Fig. 2; Said reduction gearing 2a is provided with eccentric orfice 2a-1; Connecting rod I6 is hinged between this eccentric orfice 2a-1 and the cutting saw blade 4, and referring to Fig. 3, the corresponding surface of said reduction gearing 2a and eccentric orfice 2a-1 is provided with stroke piece 2a-2; The trip piece 2a-2 touches and is provided with travel switch 7; The cylinder 8 that said travel switch 7 controls are positioned at reduction gearing 2a one side goes up and down, and the piston rod 8a and the connecting rod II9 of this cylinder 8 are hinged, and the said connecting rod II9 other end is hinged on the knife rest 5.
Also be provided with the gear on-off 10 of control cutting speed and position in the said transmission case 2.
During actual the use, chain (steel pipe etc.) is clamped in mining wind saws on the anchor clamps 11 of a side, air motor 3 makes driving shaft reach rated speed, realizes the design reciprocating speed through reduction gearing 2a.Realize falling in order to cooperate to go up and down-sawing forward-lift-back anxious returning with reciprocal coordination; Stroke piece 2a-2 and reduction gearing 2a one are synchronized with the movement; Stroke piece 2a-2 contacts with travel switch 7; Travel switch 7 itself has the ability of the initial position that rebounds, so realized the synchronous constantly of stroke piece 2a-2 and travel switch 7, the elevating movement of travel switch 7 control cylinders.Gear on-off 10 has three gears, and the adjustment through three gears realizes fast liter, work respectively, falls soon.
