Abstract
Pivot plow turns width limit adjusting mechanism, turn plow frame at hitch frame rear, the first oil cylinder for being connected between hitch frame and plow frame including hitch frame, by first rotating shaft left-right rotation peace, it is located at below first rotating shaft at left and right sides of hitch frame and symmetrical second shaft is set, second shaft is located on the first oil cylinder lower end running track, cam is installed respectively two the second shaft front ends, two cams are symmetrically arranged, the second oil cylinder is connected between two cam swings ends, mandril is respectively set two shaft rear ends, two mandrils are symmetrically arranged.It is time saving and energy saving that it adjusts operation, improves ploughing work efficiency, pivot plow is made to turn width limit adjusting mechanism two sides synchronization action, guarantees that pivot plow two sides turn that width is consistent, and arable land furrow etc. is deep.
Description
Technical field
The utility model relates to plough that pivot plow more particularly to a kind of pivot plow is used to turn width limit adjusting mechanism.
Background technique
Pivot plow is important agro-farming apparatus, mainly turns after hitch frame by hitch frame, by shaft left-right rotation peace
The plow frame of side, the oil cylinder being connected between hitch frame and plow frame, the ploughshare being mounted on plow frame are constituted.When ploughing work, with
The change for the tractor direction of travel connecting with hitch frame needs telescopic oil cylinder or so pivot plow frame, and then makes the plough on plow frame
Ploughshare is located at side where arable land.Due in ploughing work, the ground of different arable land where the wheel of tractor two sides condition leads to tractor
And pivot plow is integral inclined or sagging, the underframe clearance on plow frame also changes correspondingly, and then needs according to different arable lands condition
It adjusts pivot plow and turns width, ploughshare is made to be in sustained height always, it is ensured that it is deep to plough furrow etc..
It is to be vertically installed at left and right sides of hitch frame rear end by screw thread that existing pivot plow, which turns width limit adjusting mechanism,
Jackscrew, the jackscrew are located on the running track of oil cylinder lower end, by manual adjustment jackscrew tip height, limit the flexible length of oil cylinder
Degree, and then limit pivot plow and turn width.This pivot plow turns width limit adjusting mechanism and adjusts time-consuming and laborious, the ploughing work efficiency of operation
It is low, and two sides jackscrew because caused by adjusting respectively two jackscrews height it is inconsistent, cause pivot plow two sides to turn inconsistent a, ploughed furrow
Ditch is deep mixed.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem, to provide a kind of pivot plow and turn width limit adjusting mechanism, is adjusted
Section operation is time saving and energy saving, improves ploughing work efficiency, and pivot plow is made to turn width limit adjusting mechanism two sides synchronization action, guarantees overturning
It is consistent that plough two sides turn width, and arable land furrow etc. is deep.
The technical solution of the utility model is:
Pivot plow turns width limit adjusting mechanism, including hitch frame, is turned after hitch frame by first rotating shaft left-right rotation peace
The plow frame of side, the first oil cylinder being connected between hitch frame and plow frame, are characterized in that at left and right sides of hitch frame and are located at
Symmetrical second shaft is set below first rotating shaft, second shaft is located on the first oil cylinder lower end running track,
Cam is installed in two the second shaft front ends respectively, and two cams are symmetrically arranged, and is connected between two cam swings ends
Mandril is respectively set two shaft rear ends in two oil cylinders, and two mandrils are symmetrically arranged.
Further preferably, the mandril is connected through a screw thread with corresponding shaft, is screwed mandril and is adjusted mandril upper end level, right
Pivot plow turns width and further limits.
The beneficial effects of the utility model are:
Cam, two cams or so pair are installed due to being symmetrical set the second shaft front end at left and right sides of hitch frame
Claim arrangement, connects the second oil cylinder between two cam swings ends, mandril, two mandril left sides are respectively set two shaft rear ends
The right side is arranged symmetrically.Flexible second oil cylinder drives two cam relative synchronization rotations, and then drives the top of two the second shaft rear ends
Bar rotates synchronously, and thereby synchronously adjusts two mandril upper end levels, has adjusted the flexible length of the second oil cylinder corresponding with two mandrils
Degree, that is, have adjusted pivot plow two sides rotation to the left and right turns width, and adjusting operation is time saving and energy saving, improves ploughing work efficiency, makes
The mandril relative synchronizations of two sides rotates, and guarantees that pivot plow two sides turn that width is consistent, and arable land furrow etc. is deep.
Detailed description of the invention
Fig. 1 is the perspective view I of the utility model；
Fig. 2 is the perspective view II of the utility model；
In figure: 1- hitch frame, 2- first rotating shaft, 3- plow frame, the first oil cylinder of 4-, the second shaft of 5-, 6- cam, the second oil of 7-
Cylinder, 8- mandril.
Specific embodiment
As shown in Figure 1 and Figure 2, pivot plow turns width limit adjusting mechanism, including hitch frame 1, passes through 2 left/right rotation of first rotating shaft
Dynamic peace turns plow frame 3 at 1 rear of hitch frame, the first oil cylinder 4 for being connected between hitch frame 1 and plow frame 3；In hitch frame 1 or so
Two sides, which are located at below first rotating shaft 2, installs symmetrical second shaft 5, and second shaft 5 is located at 4 lower end of the first oil cylinder fortune
On row track, cam 6 is installed respectively two 5 front ends of the second shaft, two cams 6 are symmetrically arranged, and put in two cams 6
The second oil cylinder 7 is connected between moved end, and mandril 8, two 8 bilateral symmetry cloth of mandril are installed by screw thread respectively two shaft rear ends
It sets.
When the first plough of operation of arable land, tractor two sides wheel is located at land surface, and the second oil cylinder 7 flexible first rotates mandril
8, so that 8 upper end level of mandril is in extreme lower position, then flexible first oil cylinder 4 rotates plow frame 3, acts against 4 lower end of the first oil cylinder
8 upper end of mandril, the ploughshare lower end connecting at this time with plow frame 3 are in extreme lower position, plough furrow for land surface.
When the second plough of operation of arable land, tractor is located at furrow side wheel and is located in furrow, and tractor rolls tiltedly to furrow, first
Second oil cylinder 7 that first stretches rotates mandril 8, moves up 8 upper end level of mandril, then flexible first oil cylinder 4 rotates plow frame 3, makes first
4 lower end of oil cylinder acts against 8 upper end of mandril, and ploughshare lower end when adjusting the ploughshare lower end height connecting with plow frame 3 and the first plough is high
It is deep to spend equal, furrow and first when guarantee second is ploughed are ploughed furrow etc..
After arable land operation third plough when operation, tractor two sides wheel is respectively positioned in furrow, though tractor does not tilt,
Vehicle body sink, and the second oil cylinder 7 flexible first rotates mandril 8, moves up 8 upper end level of mandril, then flexible first oil cylinder, 4 one-way plough
Frame 3 makes 4 lower end of the first oil cylinder act against 8 upper end of mandril, when the ploughshare lower end height and second that adjusting is connect with plow frame 3 are ploughed
Ploughshare lower end height is equal, and it is deep to guarantee that third ploughs later furrow of furrow and the second plough etc..
The above are only specific embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
