Abstract
The utility model relates to a pneumatic felling saw, and belongs to a felling tool. The pneumatic felling saw comprises an air pump, an air pump shell, a transmission chain wheel, a cutting saw plate, a cutting saw chain and an air volume control valve, wherein the transmission chain wheel is connected with an output shaft of the air pump by using a flat key; a fixed joint protective plate is arranged between the air pump shell and the cutting saw plate; long slot regulating holes are formed in the corresponding positions on the cutting saw plate and the fixed joint protective plate; and the cutting saw plate is fixedly connected with the fixed joint protective plate by two bolts. According to the pneumatic felling saw, an air source is used as power, the anti-explosion requirement is avoided, and the elasticity of the cutting saw chain is adjustable, so that the pneumatic felling saw is convenient to maintain in time in the long-term using process.
Description
Technical field
The utility model relates to a kind of felling tool, particularly relates to a kind of pneumatic felling saw.
Background technology
Under coal mine, in the production process,, usually need to add strong supporting with round log for the relatively poor part location of top board; The length of round log needs to decide according to the scene use, cuts round log in the past and leans on manual work to carry out sawing with handsaw entirely, and is time-consuming; Especially when running into top board and need a large amount of round logs to handle,, often need drop into three to six people and cut the saw round log specially for satisfying the supporting needs; Increase working strength of workers, reduced economic benefit of enterprises.Belong to non-antiknock device though the electric chain saw operating efficiency is higher, under mine, can't use with gas, coal dust explosion hazard.In the long-term use of chain saw, chain is loosening easily simultaneously, safeguards that difficulty is very big, thereby the operate as normal that influences chain saw is used.
The utility model content
The purpose of the utility model is: for overcoming the deficiency of prior art, provide a kind of chain degree of tightness adjustable and be the pneumatic felling saw of power source with the pressure wind.
The technical scheme of the utility model
:
A kind of pneumatic felling saw; Contain air pump, air pump housing, drive sprocket, cut the saw plate, cut saw chain bar and volume control damper; Drive sprocket adopts flat key to be connected with the output shaft of air pump; The air pump housing is provided with between the plate and is fixedly connected protective plate with cutting saw, and the corresponding position is respectively equipped with the elongated slot adjustment hole on cutting the saw plate and being fixedly connected protective plate, cuts to saw plate and be fixedly connected protective plate and link together through two bolt.Said fixed connection protective plate is a fanning strip, and fan-shaped circumference is a dentation.
The drive sprocket arranged outside has back of the body cap, and back of the body cap is provided with approximate rectangular protective cover outward.
The beneficial effect of the utility model is:
The pneumatic felling saw deft design of this utility model, easy to operate, to cut saw efficient high, especially handling aspect the roof fall of coal mine lower roof plate, for the quality time has been saved in the timely supply of round log.
2. the pneumatic felling saw employing pressure wind of this utility model is a power source, and coal mine downforce wind is taken conveniently, no requirement of explosion proof, and security performance is good.
3. the saw plate that cuts of the pneumatic felling saw of this utility model is provided with the elongated slot adjustment hole, cuts degree of tightness and the effective cutting length that saw plate and the relative position that is fixedly connected protective plate realize cutting under the different situations saw chain bar through adjusting.
Description of drawings

Fig. 2 is the plan structure sketch map of the pneumatic felling saw of the utility model.
Label 1 is the blast pipe of this pneumatic felling saw among the figure, and label 2 is an air-valve, and label 3 is the air pump housing, and label 4 is the air pump gear; Label 5 is a flat key, and label 6 is a drive sprocket, and label 7 is the elongated slot adjustment hole, and label 8 is for cutting the saw plate; Label 9 is for cutting the saw chain bar, and label 10 is for being fixedly connected protective plate, and label 11 is a bolt; Label 12 is for cutting the saw handle, and label 13 is a protective cover, and label 14 is back of the body cap.
The specific embodiment
A kind of pneumatic felling saw referring to Fig. 1 and Fig. 2, is a power with the wind regime; Wind gets into air pump from blast pipe 1 and drives 4 rotations of air pump gear, and the size of air quantity can be provided with air pump housing 3 through air-valve 2 controls outside air pump; Be equipped with on the air pump housing and cut saw handle 12, the output shaft of drive sprocket 6 and air pump is connected with flat key 5, and drive sprocket 6 and then rotated when air pump gear 4 rotated; Cut saw chain bar 9 cutting speed running on saw plate 8 and the drive sprocket 6 thereby make, cut timber.Be fixedly connected protective plate 10 cutting to be equipped with between saw plate 8 and the air pump housing 3; Being fixedly connected protective plate 10 is a fanning strip that circumference is a dentation; Have elongated slot adjustment hole 7 at fixed connection protective plate 10 and the correspondence position that cuts saw plate 8; Cut saw plate 8 and be fixedly connected protective plate 10 and be fixed together through two bolts 11 of elongated slot adjustment hole 10 usefulness; Cut saw plate 8 and the relative position that is fixedly connected protective plate 10 through adjusting, realize cutting under the different situations degree of tightness and the effective cutting length of saw chain bar 9.Arranged outside at drive sprocket 6 has back of the body cap 14, and back of the body cap 14 is outside equipped with protective cover 13.
Claims (3)
1. pneumatic felling saw; Contain air pump, air pump housing, drive sprocket, cut the saw plate, cut saw chain bar and volume control damper; Its sign is: drive sprocket adopts flat key to be connected with the output shaft of air pump; The air pump housing is provided with between the plate and is fixedly connected protective plate with cutting saw, and the corresponding position is respectively equipped with the elongated slot adjustment hole on cutting the saw plate and being fixedly connected protective plate, cuts to saw plate and be fixedly connected protective plate and link together through two bolt.
