Adopt the agronomy of zero tillage in a lot of regional farmlands, no longer plough the soil behind the crop harvesting such as wheat, barley and highland barley, rape, and be to use no-tillage system to plant the next round crop, therefore the ditch of opening in the wheatland last one year still exists, but ditch shape is because factor affecting such as bubble, weathering, these old ditches have silted up to shoal and have narrowed down, and need excavate again with desilting old ditch and deepen to widen.But because the cunning of existing ditching machine is stuck up just below frame arm, cutterhead near ditching machine, when old ditch being repeated to ditch with this ditching machine, can be because the sliding edge that just sticks up near old ditch, do not note slightly slipping into Lao Gouzhong with regard to slope effect owing to old furrow rim, after cunning was stuck up and slipped in the old ditch, bottom of trench will deepen suddenly, made diesel engine speed reduction even flame-out because of the load of ditching strengthens suddenly.On the other hand, existing sleeve pipe side has only a screw tightening cunning to stick up post, rather than runs through and slidingly stick up post, and tightening power is not enough, can make the sliding post slippage of sticking up after loosening.

Summary of the invention

Technical problem to be solved by this invention will overcome the defective that prior art exists exactly, provides a kind of and can open new ditch common Tanaka, can repeat the sliding-raising mechanism of ditcher structure of ditching again in old ditch again.

Sliding-raising mechanism of ditcher of the present invention, comprise the enclosed type sleeve pipe and sliding the sticking up that are arranged at ditching machine frame arm front end, a side of enclosed type sleeve pipe is provided with bolt hole, sliding cunning of sticking up is stuck up post and is provided with a plurality of bolts hole, it is characterized in that: other is provided with a U type and connects piece, and two mullions that the U type connects piece are provided with bolt hole; Both available bolt sticks up post with cunning and directly is fixed on the enclosed type sleeve pipe, and also available bolt connects piece with the U type earlier and is fixed on the enclosed type sleeve pipe, the more sliding post that sticks up is fixed by bolts on another mullion that the U type connects piece.

Sliding-raising mechanism of ditcher of the present invention comprises that the cunning that is arranged at ditching machine frame arm front end is stuck up folder and cunning is stuck up; It is opening that cunning is stuck up the folder front end, and the middle part, two sides is arranged with bolt hole; Sliding cunning of sticking up is stuck up post and is provided with a plurality of bolts hole; It is characterized in that: other is provided with a U type and connects piece, and two mullions that the U type connects piece are provided with bolt hole; Both available bolt sticks up post with cunning and directly is fixed on sliding sticking up on the folder, and also available bolt connects the U type piece earlier and is fixed on sliding sticking up on the folder, the more sliding post that sticks up is fixed by bolts on another mullion that the U type connects piece.

The front portion that described cunning is stuck up the folder two sides is arranged with clamp bolt hole, and bolt passes the clamp stud hole and the sliding folder two sides of sticking up can be clamped.

The rear portion that described cunning is stuck up folder is provided with the adjusting bolt hole, wherein revolves to put the adjusting bolt, in order to regulate sliding angle of sticking up post.

Mechanism of the present invention connects piece without the U type, and the sliding post that sticks up directly runs through and is assemblied in sliding sticking up in folder or the enclosed type sleeve pipe, still adapts to common flat Tanaka and opens new ditch.Because sliding sticking up more drawn close to the center of ditching machine, by sliding stick up the resistance that produces with ground friction to tractor before the time angular force just Yu is little, the linearity of trench digging is also good more.When needs repeat to ditch to old ditch, connect the U type and connect piece, cunning is stuck up post connect with another mullion that the U type connects piece, sliding just sticking up moved and away from frame arm on the side, thereby make sliding sticking up that necessary width arranged apart from limes marginis, when old ditch was repeated to ditch once more, sliding sticking up just was not easy landing and goes into Lao Gouzhong.Because though old ditch is shallow, but still low than field face, and soil moisture is big in the ditch, soil compactibility is low, the knife cutting resistance is little, therefore the direction of advance of cutterhead also trends towards walking along Lao Gou, although sliding stick up the other back of moving and add the angular force that ambassador advances apart from the distance at tractor center and strengthen, but have along taxis during owing to the cutterhead trench digging along old ditch running, and sliding sticking up after ditch is outlying, influenced by the slope of old furrow rim, so just be not easy landing in old ditch, the feasible operation that old ditch is repeated to ditch can be carried out smoothly.
