Abstract
The utility model discloses an adjustable tripod traction frame comprising a traction cross beam. The adjustable tripod traction frame further comprises a main traction longeron and an auxiliary traction longeron. The main traction longeron and the auxiliary traction longeron are respectively connected on the traction cross beam in a movable mode. One end of the auxiliary traction longeron, away from the traction cross beam, is connected with a beam arm of the main traction longeron through a fine adjustment lead screw in a movable mode. By adjusting the fine adjustment lead screw of the auxiliary traction longeron, the deviating force produced in the advancing of the heavy harrow is capable of being completely eliminated, so that the harrow body and the advancing direction of the tractor are kept in the same direction, and the extra power of the tractor is saved.
Description
Technical field
The utility model relates to a kind of hitch frame, relates in particular to a kind of adjustable tripod hitch frame.
Background technology
In the prior art, hitch frame can be connected heavy duty harrow the assurance heavy duty harrow effectively works under the traction of means of transport with means of transport, but the adjusting of existing hitch frame is that method is equidistant, extensive style, can not finely tune, and can not eliminate the traction angular force fully.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of adjustable tripod hitch frame.
To achieve these goals, the technical solution adopted in the utility model is: a kind of adjustable tripod hitch frame, comprise the traction crossbeam, also comprise main traction longeron and secondary traction longeron, main traction longeron and secondary traction longeron are movably connected on respectively on the traction crossbeam, and secondary traction longeron is movably connected on the beam arm of main traction longeron by the fine setting screw mandrel away from an end of traction crossbeam.
As preferably, be flexibly connected as hinged.
Compared with prior art, the utility model has the advantage of: 1, by regulating the fine setting screw mandrel of secondary traction longeron, the angular force that heavy duty harrow can be produced in the advanced person is thoroughly eliminated, and rake body and tractor direction of advance are consistent, and saves the extra power of tractor.2, intensity obviously improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, main traction longeron; 2, secondary traction longeron; 3, fine setting screw mandrel; 4, traction crossbeam.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of embodiment of the present utility model, consult Fig. 1, the utility model comprises traction crossbeam 4, also comprise main traction longeron 1 and secondary traction longeron 2, main traction longeron 1 and secondary traction longeron 2 are movably connected on respectively on the traction crossbeam 4, and secondary traction longeron 2 is movably connected on the beam arm of main traction longeron 1 by fine setting screw mandrel 3 away from an end of traction crossbeam 4.Be flexibly connected as hinged.
The utility model is simple in structure, and modern design has the following advantages, and 1, by regulating the fine setting screw mandrel 3 of secondary traction longeron 2, the angular force that heavy duty harrow can be produced in the advanced person is thoroughly eliminated, and rake body and tractor direction of advance are consistent.Save the extra power of tractor.2, intensity obviously improves.
Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
