Part, and do not get rid of other element or other part.
As shown in Figure 1 to Figure 3, according to a kind of embodiment of the specific embodiment of the invention it is: a kind of green
The obstacle avoidance apparatus of hedge trimming tool, comprising: knife rest 1, dynamometer link 4, device for measuring force 3 and rotation dress
Put 5, wherein:
As it is shown in figure 1, knife rest 1 is in arc-shaped, and the side of this knife rest 1 indent is towards front, knife rest 1
For installing several trimming tools 2, the two ends, left and right of knife rest 1 are forwardly convex relative to trimming tool 2.
The two ends, left and right of dynamometer link 4 are connected with the two ends, left and right of knife rest 1 by two device for measuring force 3 respectively, with
Cross at the front of several trimming tools 2, and dynamometer link 4 is higher than trimming tool 2.As in figure 2 it is shown,
Each device for measuring force 3 includes sleeve 31, pressure sensor 35 and spring 34, and sleeve 31 is fixedly installed
Before and after the end of knife rest 1, sleeve 31, two ends are respectively arranged with protecgulum 33 and bonnet 32, and sleeve
The front portion of 31 is provided with a chute 36 corresponding with dynamometer link 4.The end of dynamometer link 4 passes chute 36
And extending in the endoporus of sleeve 31, the two ends of dynamometer link 4 can be respectively along on two sleeves 31
Chute 36 carries out slide anteroposterior.Pressure sensor 35 is fixedly installed on the rear end of sleeve 31.Spring 34
It is sheathed in sleeve 31, and it is located between the end of pressure sensor 35 and dynamometer link 4, works as survey
When power bar 4 is extruded by barrier, the two ends of dynamometer link 4 slide backward along chute 36 respectively and compress
Spring 34,34 pressure transmission of spring are to pressure sensor 35, close to obstacle effect at dynamometer link 4
On spring 34 pressure experienced of one end of position more than away from obstacle effect position on dynamometer link 4
The active force of the spring 34 of the one end put, therefore detected by the pressure sensor 35 of two device for measuring force 3
Force value different, just can calculate barrier and dynamometer link according to the pressure differential of two pressure sensors 35
The position of 4 contacts.Tumbler 5 is connected with one end of knife rest 1, and tumbler 5 can drive knife rest 1
Rotate around the one end being connected with tumbler 5.After the position running into barrier being detected, by turning
Dynamic 5 knife rests 1 of device rotate backward suitable position, so that trimming tool 2 avoiding obstacles.Excellent
Selection of land, as it is shown on figure 3, tumbler 5 include base 54, wobble gear 58, swing tooth bar 57 with
And drive mechanism, one end of knife rest 1 is rotatably arranged on base 54, wobble gear 58
It is arranged at knife rest 1 that the one end on base 54 is fixing to be connected, it is preferable that wobble gear 58 is a sector
Gear.Swing tooth bar 57 to be connected with wobble gear 58 engagement, by mobile next before and after swinging tooth bar 57
Wobble gear 58 is driven to rotate, so that knife rest 1 can carry out swing.Drive mechanism is used for driving pendulum
Carry-over bar 57 moves forward and backward.It is further preferred that drive mechanism include screw mandrel case 53, screw mandrel 55,
Feed screw nut 56, decelerator 52 and motor 51, screw mandrel case 53 is fixing with base 54 to be connected, screw mandrel
55 are rotatably arranged in screw mandrel case 53；Feed screw nut 56 is connected with screw mandrel 55 engagement,
Swing tooth bar 57 to be fixedly installed on feed screw nut 56, when screw mandrel 55 carries out rotating, it is possible to drive silk
Stem nut 56 moves forward and backward, with order about swing tooth bar 57 move forward and backward.Motor 51 is to watch
Taking motor, it is connected with screw mandrel 55 by decelerator 52, to drive screw mandrel 55 to rotate.
During the pruning to hedgerow, if press rods 4 being produced bigger resistance because running into barrier
During power, the two ends of press rods 4 will compress the spring 34 of two device for measuring force 3 backward, and control system is led to
Cross the pressure difference value that two pressure sensors 35 detect and come the position at disturbance in judgement thing place, then start
Motor 51 drives screw mandrel 55 to rotate, and feed screw nut 56 drives swing tooth bar 57 to move, thus logical
Cross wobble gear 58 band movable knife rack 1 to swing backward, and determine knife rest 1 according to the position at barrier place
The angle that swings backward also stops the regular hour, so that trimming tool 2 can avoid barrier completely,
Then again through the reversion of motor 51, knife rest 1 is made again to be swung forwards to original position, and spring 34
Also reset with dynamometer link 4, to re-start the work of normal hedge trimming,.
The present invention can come smart by measuring the barrier such as trunk, electric pole correspondence position on dynamometer link 4
Really driving knife rest 1 to carry out deflecting avoidance, it can realize automatic obstacle-avoiding neatly, to protect trimming tool 2
With the generation preventing contingency.
The aforementioned description to the specific illustrative embodiment of the present invention illustrates that and the purpose of illustration.
These descriptions are not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned
Teaching, can much change and change.The purpose selected exemplary embodiment and describe exists
In explaining the certain principles of the present invention and actual application thereof, so that those skilled in the art can be real
Now and utilize the various different exemplary of the present invention and various different selection and change.
The scope of the present invention is intended to be limited by claims and equivalents thereof.
