2nd, application method：
（One）Clamping and positioning
When initial, hold-fast body 300 is in horizontal position as illustrated in figures 4-5, driver's driving operation locomotive 100 to trees
Front suitable position, control hold 340 both ends piston rod of hydraulic cylinder tightly simultaneously to contract, drive right folded arm bar 310 and left folded arm
Bar 330 is drawn close along the holding sliding slot 352 on linkage bull stick 350 to centre, and as shown in figure 14, at both ends, the pulling force of piston rod is made
Under, trunk 900 is clamped in centre by the V shaped slab 311 on right folded arm bar 310 and left folded arm bar 330.
（Two）Lumbering operation
After right folded arm bar 310 and left folded arm bar 330 clamp trees, the lumbering left hydraulic cylinder 210 in crotch 280 is supported
The forward movement synchronous with lumbering right piston bar 271 of lumbering left piston bar 211 is respectively driven with right hydraulic cylinder 270 of lumbering, drive is cut down
Wooden slide motor 230 is moved forward with lumbering synchronous slider 260 along the horizontal lumbering sliding slot 285 on support crotch 280 is synchronous,
Slide motor 230 of lumbering simultaneously starts the left sprocket wheel 220 of driving lumbering and rotates, and timber cutting chain saw 240 is driven to run, timber cutting chain saw 240
It is pushed forward, trunk 900 is sawed-off from bottom.
（Three）Rotate trunk
As shown in figure 15, trunk 900 pulls 370 edge of overturning sliding block by the piston rod after sawed-off, overturn on hydraulic cylinder 380
The overturning sliding slot 121 on branches and leaves collecting box 120 slides backward, then pulls linkage bull stick 350 around bull stick by drive link 360
Hole seat 111 rotates clockwise, and right folded arm bar 310 and left folded arm bar 330 clamp trunk 900, and with linkage bull stick 350 jointly to
An angle of 90 degrees degree is rotated afterwards, puts 900 level of trunk, and Figure 16 is the state that 900 level of trunk is put, and then holds hydraulic cylinder tightly
The 340 right folded arm bars 310 of promotion and left folded arm bar 330 slide in and out, and are released trunk 900, while fall and drive guide wheel first
601 and second drive on guide wheel 602, and trunk 900 is limited between the slope bar 123 of 120 both sides of branches and leaves collecting box, prevents
Trunk 900 shakes excessive.
（Four）Trunk linear measure longimetry
900 level of trunk, which is fallen, to be driven in the first driving guide wheel 601 and second on guide wheel 602, and range sensor 604 starts,
Preferably by ultrasonic distance measuring module, principle is range sensor 604 used：Ultrasonic transmitter is to 900 direction of trunk
Emit ultrasonic wave, start timing while emission time, 900 top of trunk is encountered when ultrasonic wave is propagated in air just at once
It returning, ultrasonic receiver receives back wave and just stops timing immediately, and the aerial spread speed of ultrasonic wave is v, and according to
The time difference t for measuring transmitting and receiving echo of timer record, it is possible to calculate launch point to the distance on 900 top of trunk
S1, i.e. S1=vt/2, and since timber cutting chain saw 240 is constant with respect to the height on ground, different trees are homogeneous by sawed-off height
Together, thus after trunk 900 is rotated by 90 ° trunk 900 by the distance L of sawed-off position and launch point be definite value, it is possible thereby to
To trunk 900 by length S2=L-S1 after sawed-off.
（Five）Trimming leaf
First driving guide wheel 601, second drives guide wheel 602 and third driving guide wheel 603 to rotate clockwise simultaneously, is rubbing
Power effect is lower to drive trunk 900 to move backward, when trunk 900 is by beta pruning instrument 400, beta pruning left hydraulic cylinder 420 and beta pruning
Right hydraulic cylinder 440 pushes left beta pruning blade 410 and right beta pruning blade 430 to be drawn close to centre simultaneously, and trunk 900 continues to move back
It is dynamic, it can be cut off when branches and leaves pass through left beta pruning blade 410 and right beta pruning blade 430 by blade, and fall into branches and leaves collecting box 120
In.
（Six）Trunk saws section
When initial, saw section chain saw 540 is located at the bottom of left sliding slot column 510 and right rail column 590, and trunk 900 continues
It moves backward, and passes through between left sliding slot column 510 and right rail column 590, guide wheel group is driven to stop operating at this time, saw Duan Zuo
Hydraulic cylinder 570 and the saw right hydraulic cylinder 580 of section push saw section slide motor 520 and saw segment sync sliding block 550 along vertical saw respectively
Section sliding slot 511 synchronizes upward sliding, while saws section slide motor 520 and start that the saw left sprocket wheel 530 of section is driven to rotate, and drives saw section chain
540 operation of saw, saw section chain saw 540 is pushed upwards, and trunk 900 is sawed-off from the bottom up, and falling into trunk by sawed-off part receives
In header 130, guide wheel group is then driven to continue that trunk 900 is driven to stop operating after moving backward a distance, saws the left hydraulic pressure of section
Cylinder 570 and the saw right hydraulic cylinder 580 of section pull saw section slide motor 520 and saw segment sync sliding block 550 to be slided along vertical saw section respectively
Slot 511 synchronizes slide downward, and saw section chain saw 540 is moved downward with saw section slide motor 520 and saw segment sync sliding block 550, will be set
Dry 900 is sawed-off from top to bottom, this motion process of repetition, which makes chain saw pump, to be cut into pieces trunk 900, and
All collect in trunk collecting box 130.
（Seven）Diameter measurement
The principle of correlation photoelectric sensor is：Transmitting terminal emits feux rouges or infrared, and receiving terminal receives, and has object process,
Light is cut off, just output signal.In section utensil 500 is sawed, photoelectric sensing transmitter 522 is fixed on saw by transmitter frame 521
On section slide motor 520, photoelectric sensing receiver 552 is fixed on by receiver frame 551 on saw segment sync sliding block 550, saws section
During chain saw 540 moves up and down photoelectric sensing transmitter 522 and photoelectric sensing receiver 552 can it is synchronous therewith on move down
Dynamic, when the signal that photoelectric sensing transmitter 522 emits is blocked by trunk 900, signal output is sent out by timer record signal
The time T for changing, piston rod at the uniform velocity push saw section slide motor 520 and saw segment sync sliding block 550 to slide up and down, movement speed
V is denoted as, then can measure trunk 900 by the diameter D=VT at sawed-off position.
3rd, the above-mentioned substantive distinguishing features of the utility model directly bring following progress effect：
Right folded arm bar 310 and left 330 end of folded arm bar are equipped with V shaped slab 311 so that have four when trunk 900 is clamped
A stress point, when trunk 900 rotates more securely；Overturning hydraulic cylinder 380 drives drive link by overturning sliding block 370
360, trunk 900 is turned into 100 top of operation locomotive and carries out the operations such as beta pruning and saw section, saves space, and avoid trunk
900 block pilot's line of vision.
