60, arrangement control handle 441 in side where finger is closed on handle 60, control handle 441 is the inlet pipe being arranged in hydraulic motor 40
The lever of switch valve 44 on 41.
The length direction of handle 60 is to upwardly extend arrangement from 40 position of hydraulic motor, in figure 3, band saw blades 30
Positioned at the lower left position of handle 60, being arranged so can utilize the weight with saw to implement sawing, be equivalent to band saw blades directly
30, which are close to band cutting material, can be easily accomplished sawing operation.Side arrangement control handle 441 is exactly where closing on finger on handle 60
In order to facilitate the operation, it controls, i.e., palm is bonded with handle 60, and finger can stir control handle 441, and operating position is convenient, timely.
Preferably, it is connected with back liquid valve group on the liquid back pipe road 42, it includes normal opened type two-position valve to return liquid valve group
70, chamber where the cooling extinguishing arc pipeline 43 is communicated to the spool of normal opened type two-position valve simultaneously drives in the spool displacement to valve
At closed channel.Under normal operation, normal opened type two-position valve 70 is in normal open state, normal opened type when specified conditions occur
Two-position valve 70 is in closed channel state.
In conjunction with Fig. 3, it includes normal opened type two-position valve 70 and throttle valve 50 to return liquid valve group, and normal opened type two-position valve 70 includes valve body
71, accommodate spool 72 in the spool chamber 711 of valve body 71, spool chamber 711 is also connected with connection chamber 73, be connected to chamber 73 respectively with hydraulic pressure
The hole for back flow of motor 40 is connected to liquid back pipe road 42, and throttle orifice 721 is opened up in spool 72, and throttle orifice 721 is axially passed through along spool 72
The logical admission chamber 51 arranged and be respectively communicated with spool chamber 711 and throttle valve 50.Normal opened type two-position valve 70 and throttle valve 50 are combined
It is integrated linking structure, space can be saved.
The spool chamber 711 includes the step-like vestibule of size diameter section, and the spool 72 is to be kissed with spool chamber 711
The step-like spool closed, the connection chamber 73 are connected to the reduced diameter section vestibule of spool chamber 711, the spool chamber 711
Chamber where major diameter end face is connected to the admission chamber 51 of throttle valve 50, sheathed spring 74 on spool 72, and spring 74 provides elastic force
Trend spool 72 is moved to connection chamber 73 and 711 connected state of spool chamber.
Throttle valve 50 includes throttling valve body 53 and adjusting spool 54, and throttling valve body 53 includes admission chamber 51 and goes out sap cavity
55, admission chamber 51 and going out between sap cavity 55 has intercommunicating pore 56, fluid hole 52 to be connected to sap cavity 55 is gone out, admission chamber 51 and the valve

The cooling extinguishing arc pipeline 43 that the throttle valve 50 corresponds to setting two-way is arranged two, and normal opened type two-position valve 70 is right
Two should be arranged in throttle valve 50.Corresponding to two-way cooling extinguishing arc pipeline 43, two groups of throttle valves 50 and normal opened type two-position valve are set
70, it is ensured that can close normal opened type two-position valve in time in any cool down all the way when stopping state occurs in extinguishing arc pipeline 43
70。
Illustrate the operation principle of the present invention below in conjunction with the course of work.
When normal work, in conjunction with Fig. 2,3, the switch valve 44 in inlet pipe 41 is operated, pressure emulsified liquid passes through switch valve
44 enter hydraulic motors 40, and the revolution of band saw blades 30 of annular winding on 40 driving pulley 20 of hydraulic motor carries out sawing-like motion,
The emulsion flowed out in the liquid return hole of hydraulic motor 40 enters back the connection chamber 73 in the normal opened type two-position valve 70 in liquid valve group, and one
Part is flow back by liquid back pipe road 42 in fluid reservoir, a part enters throttle valve 50 by the throttle orifice 721 opened up in spool 72
Admission chamber 51, the emulsion in admission chamber 51, which reaches out sap cavity 55 by intercommunicating pore 56 and is connected to fluid hole 52 and flow to cooling, to disappear
Arc pipeline 43 is ejected by cooling extinguishing arc emulsion nozzle 431 on sawing active section 31；When cooling extinguishing arc pipeline 43 is because of blocking etc.
When reason cannot normally convey emulsion, cool down at this time extinguishing arc emulsion nozzle 431 can not normal injection emulsion, fluid hole
52, go out the emulsion accumulation in sap cavity 55, intercommunicating pore 56 and admission chamber 51, the emulsion of the admission chamber 51 acts on spool 72
On major diameter end face, since there are difference in size for the both ends face area of spool 72, so, the pressure that 72 left and right ends of spool are subject to
Power is different, and in conjunction with spring 74, its suffered resultant force pushes the spool 72 in Fig. 3 states to be moved to the left, and closes and is connected to chamber 73 and spool chamber
711 connection position to close connection chamber 73, that is, closes liquid back pipe road 42, for hydraulic motor 40, does not have
There are back liquid access, hydraulic motor 40 that can only just stop operating naturally.Sawing-like motion stops therewith, would not also continue to generate fire
