Spring 302, by being rotatably connected between screw rod 301 and detection bar 305, can adjust the deflection for reversing and pressing spring 302.Profit
Pressing spring 302 with torsion makes compress ground two moment of detection bar 305, is contacted with ground, it is to avoid detection bar is uneven by ground
The influence of degree and barrier, it is impossible to the position of true reflection root tuber crops.Spring 302 is pressed in the torsion of two detection bar both sides
It is independent, it is ensured that the relatively independent motion of two detection bars 305, can truly reflect respective movement characteristic.Spring is pressed in torsion
302 inner side is respectively provided with steering back-moving spring 303, and the inner side of spring 302 is pressed in the one end and torsion for turning to back-moving spring 303
Detection frame 304 is connected, and the other end is connected with the bottom of column 204.When the detection bar 305 of side touches root tuber crops
When, detection bar 305 promotes detection frame 304 to be rotated around central shaft 306, so that the steering back-moving spring 303 of side is compressed, so that
Back-moving spring 303 is turned to compress.After detection bar leaves beet, detection frame return in the presence of return spring is turned to, it is ensured that with
Equipment direction of advance it is vertical, it is to avoid because damage phenomenon is dug in crop leakage caused by detection bar position is unstable.
The controlling organization includes angular displacement sensor 801 and controller, and the angular displacement sensor 801 is fixed on detection
On frame 304, angular displacement sensor 801 is connected with controller, and controller is connected with hydraulic cylinder 406.Described controller can be adopted
With single-chip microcomputer or PLC, controller in the present embodiment using model STM32 single-chip microcomputer.When detection bar touches root tuber stem
When class crops drive detection frame to rotate, its rotational angle provides a deviator information by angular displacement sensor 801, and this is inclined
Measure and control to be arranged on the hydraulic cylinder of sliding block side by controller, flexible by hydraulic cylinder piston rod realizes sliding block and digging
What pick was shoveled moves left and right, it is ensured that digger blade can accurately excavate root tuber crops, and anti-leak-stopping digs or damage root tuber
Crops.
Digger blade 401 is driven by hydraulic cylinder 406, is moved left and right along slide bar, is directly driven by hydraulic cylinder, does not use any
The effect of applied force.After the information that receives completes one action process, digger blade can't be directly returned to centre position, but
Continue to wait next subcommand in the position of last time end-of-job, according to the regular skew of straight line, greatly reduce digger blade
Displacement path, while reduce the activity of hydraulic cylinder, reduce hydraulic cylinder temperature, ensure that hydraulic cylinder can continue to provide steady
Fixed power, when hydraulic cylinder receives information offset a certain distance, in best excavation angle so as to avoid making between crop
The damage of thing.The speed of Hydraulic Cylinder digger blade movement is determined with the time by the deviation post of crop and the gait of march of device
It is fixed.
The course of work of the present apparatus is as described below：During work, the detection bar 305 to row adjustment mechanism is located at crop respectively
Both sides, by the contact with detection bar 305 of crop outline, make detection frame 304 rotate, the angle on detection frame 304
Displacement transducer 801 collects angular displacement defection signal, and angular displacement deviator is converted into displacement deviator by controller, and passes to
Hydraulic cylinder 406, after hydraulic cylinder 406 is opened, drives sliding block 407 to translate suitable distance along slide bar 402, makes to perturb digging mechanism and is in
It is suitable to excavate position, realize the equipment during harvesting to row.
