Description
Technical field:
The utility model relates to a kind of rearmounted left side formula ditching machine bar straightening mechanism.
Background technology:
Existing Mini-type ditching machine is mounted on hand tractor more, ditch is outputed in the fields by the rotating blade on ditching machine when tractor advances, existing ditching machine has front positioning type and rear-mounted two kinds, namely so-called front positioning type is front ditching machine being arranged on tractor, its earth outputed is smooth, ditch type might as well, but problem is, engine due to tractor is in the front of axletree, light after heavy inherently, if ditching machine is arranged on engine front, cause tractor front portion overweight, need to increase counterweight at the rear of wheel shaft, considerably increase tractor deadweight like this, also must increase the load of machine and then increase energy consumption, in addition, engine front does not have special connecting portion, make ditching machine that trouble is installed, also bad operation, run into the more difficult use of situation of earth humidity, be not suitable for fraction horsepower hand tractor to use.Rear digging machine, as the term suggests be namely rear ditching machine being arranged on engine, such engine and ditching machine divide the front and back being in axletree, barycentre steadiness, but because ditching machine needs placed in the middle setting, its drawback is, rearward be unearthed with both sides during rotating blade trench digging, the earth thrown away backward makes operator to be all over the body, the earth thrown away to the right easily enters the air inlet of engine, cause engine damage, in addition, rearmounted ditching machine blade placed in the middle from operator very close to, be easy to cause injured, exist larger potential safety hazard moreover, because ditching machine is placed in the middle, cannot ditch near the place of ridge in limit, field four.Also someone attempts rear sidepiece ditching machine being arranged on tractor, but ditch could be outputed in the fields because rotating blade during trench digging need apply very large power to earth, like this, the blade being located at tractor side also can be subject to very large reaction force, tractor is caused not take the air line, and the ditch that ditching machine will be made to output straight line comes, the reaction force that operator just must be subject to overcome it the very large cross force of tractor handle applying, causes working strength greatly to increase.
The earlier application " rearmounted left side formula ditching machine " of the applicant, be provided with a kind of ditching machine machine straightening device, comprise the column be arranged in frame, the straightening plate axle be disposed in parallel on column, the straightening plate etc. be hinged on straightening plate axle, the adjustment of straightening plate regulates by the adjusting bolt be connected on base plate, the straightening plate of this device swings not freely, and convenient not to the adjustment of the amplitude of fluctuation of straightening plate.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of rearmounted left side formula ditching machine bar straightening mechanism, the left rear side of tractor is located at by ditching machine, improve safety coefficient, avoid earth to be inhaled into engine intake, also can to ditch at balk, by arranging machine straightening device in frame, scientific utilization mechanics principle stops tractor to wander off, and the straightening plate of adjusting device swings freely, amplitude of fluctuation is easy to adjust.
The utility model technical solution problem adopts following technical scheme:
Rearmounted left side formula ditching machine bar straightening mechanism, described ditching machine comprises:
Arrange L-shaped frame, the front end of described frame is connected on the connecting frame at tractor rear portion, and described frame is provided with the gearbox being in tractor rear left, and the output spline of described gearbox is driven by the actuating unit on tractor;
Described splined shaft is provided with cylinder cutterhead, and multiple blade clearance is distributed in the periphery of described cylinder cutterhead;
Arrange that be connected in described frame can the column of up-down adjustment, be installed with straightening plate axle side by side at the sidepiece of described column, the bottom of column is installed with the base plate of level, and the front end of straightening plate is hinged on described straightening plate axle;
Be provided with the swing regulation mechanism of straightening plate in the bottom of described column, described swing regulation mechanism comprises:
The unthreaded hole in arranging up and down and screwed hole is provided with in column bottom, be arranged on the through hole of front end through straightening plate of the polished rod in described unthreaded hole, and being connected with stop nut at the forward end of described polished rod, the rear end of polished rod is socketed with spring, end is connected with adjusting nut; The forward end being arranged on the screw rod in described screwed hole is tight against on the plate face of straightening plate, and on described screw rod, be provided with the locking nut be locked at by screw rod on column.
