Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment cannot be used for limiting the scope of the utility model for illustrating the utility model.
The structure of the pneumatic type wood saw of the utility model embodiment includes as shown in Figure 1 to Figure 2：Casing, and setting exist
Guide plate 2 in casing, air motor 3 and motor control mechanism by drive of high-pressure gas, the chain 5 being surrounded on guide plate 2,
The sprocket wheel 6 being installed on 3 front output shaft of air motor；Motor control mechanism is for controlling 3 drive sprocket 6 of air motor；Sprocket wheel 6 drives
Dynamic chain 5 does turnover campaign to complete sawmilling work along guide plate 2.
Casing 1 includes left cabinet 11, right cabinet 12, upper casing 13 and lower casing 14；Upper casing 13 and lower casing 14 are fixed,
Main case is formed, guide plate 2, air motor 3 and motor control mechanism 4 are installed in main case；Left cabinet 11 is fixed on host
On the left of shell；Right cabinet 12 is fixed on the right side of main case.
Motor control mechanism 4 includes switch 41, air inlet pipe 42, motor driving tracheae 43 and inlet suction port 44；Inlet suction port
44 are installed on 14 tail end of lower casing；42 first end of air inlet pipe is connect with switch 42, and second end is connect from inlet suction port 44；Motor
Driving 43 first end of tracheae is connect with switch 41, and second end is connect with air motor 3；Switch 41 is for controlling air inlet pipe 42 and horse
Up to the ventilation or state of dying driven between tracheae 43,41 are turned on the switch, air inlet pipe 42 and motor driving tracheae 43 are in ventilation
State, high pressure gas flow to motor from air inlet pipe 42 and drive tracheae 43 to drive air motor 3.
Air motor 3 is equipped with gas-guide tube 31；Gas-guide tube 31 is fixed on lower casing 14, and 31 first end of gas-guide tube and gas
The exhaust outlet connection of dynamic motor 3 blows down the sawdust on chain 5 by the discarded guiding of air motor 3 to close to chain 5, and from
The air guide port blowout that left cabinet 11 opens up, makes chain 5 have better cutting effect.
Air guide port is equipped with chip removal mouth, and chip removal mouth is equipped with sawdust collecting bag, can the sawdust that sawmilling generates be collected into wood
It considers to be worth doing in collecting bag, facilitates to do sawdust and further utilize；And sawdust is collected for convenience, the position of chip removal mouth is arranged in air guide
On mouth.
