A kind of scalable pneumatic trees orchard shears operation principle:
1, on blade, move shear history
As shown in Figure 1, the pull operation hole is downward, drives bracing wire 5-9, arm-tie 5-6 and spool 5-4 (diagram is left is that upwards the right side is downward) downwards.Inlet valve hole 5-10(is connected with gas receiver) be plugged give vent to anger valve opening 5-11(cylinder top tracheae 7 and tube connector 8) with the spool post gap, being communicated with (external world is led in gap), high pressure gas bleeds off by give vent to anger valve opening 5-11 and spool post gap;
Set a raft going out in the gap of give vent to anger valve opening 5-11 → spool and the spool bore 5-12 of the side air admission hole 3-8 of inverting seat removable cover lower air chamber D gas by inverting seat → threeway 3-6 → tube connector 8 → Pneumatic valve, removable cover moves down under the pressure of air cavity A gas after cylinder piston, the side venthole 3-9(that removable cover seals inverting seat downwards prevents that high pressure gas from leaking), cylinder is communicated with by connectivity slot 3-10 with gas receiver; Gas receiver inner high voltage gas powerful promotion of moment cylinder piston forward.At the same time, gas before cylinder piston is set a raft going out by the gap of cylinder top tracheae 7 → threeway 3-6 → tube connector 8 → give vent to anger valve opening 5-11 → valve core and spool bore 5-12, before cylinder piston, there is no resistance, the movable section of piston driving fast upwards, realizes on the moment blade moving shearing.
2, blade moves down the return process
Decontrol handle hole, bracing wire 5-9, arm-tie 5-6 and spool 5-4 return under the effect of valve spring 5-2.The gap of spool and spool bore 5-12 is in communication with the outside and is cut off.Inlet valve hole 5-10(connects gas receiver) valve opening 5-11(communicates with tube connector 8 with cylinder top tracheae 7 with giving vent to anger) be connected.Gas receiver inner high voltage gas, by inlet valve hole 5-10 → give vent to anger valve opening 5-11 → cylinder top tracheae 7 and tube connector 8 → cylinder upper cover hole, enters air cavity B above cylinder piston.Simultaneously hyperbar enters the commutation air cavity D under removable cover by threeway 3-6 → inverting seat hole 3-8, under the thereunder effect of spring force of the upper and lower air pressure balance of removable cover at this moment, removable cover, upwards moves rapidly a cylinder and isolates with gas receiver.The gas of cylinder piston back is in communication with the outside by the side venthole 3-9(of removable cover mesopore 3-11 → inverting seat) discharge rapidly.Like this, under the acting in conjunction of the high pressure gas effect of the piston top of cylinder and the discharge of piston lower gas, the piston driving movable blades moves down rapidly realizes return.
