Abstract
The utility model relates to a tractor trailer device which comprises a left fixing frame, a right fixing frame and a traction frame, and the left fixing frame and the right fixing frame are arranged symmetrically. The tractor trailer device is characterized in that the traction frame comprises a traction plate and a fixing plate, the front end of the traction plate is arranged on the lower portions of the left fixing frame and the right fixing frame through the fixing plate, the rear end of the traction plate is provided with a pin hole, and a pin shaft is arranged in the pin hole. The tractor trailer device has the advantages that the tractor trailer device is arranged on the lower portion of a rear axle shell, and a power output shaft is arranged on the upper portion of the rear axle shell, so that the tractor trailer device and the power output shaft are compatible and can carry out related operation at the same time without mutual influence, and work efficiency is improved.
Description
Technical field
The utility model relates to trac., relates in particular to a kind of trail device for tractor.
Background technology
Because trac. is multiplex in agricultural tillage, so just require trac. to have the function of traction miscellaneous equipment operation.Its trailed equipment must have be connected firmly, the failure-free tractive property, to guarantee to draw normally towage.And the trailed equipment of most trac. is arranged on the tractor rear axle housing, and the drawbar frame of its trailed equipment overlaps with the position of power take-off shaft on setting height(from bottom), and this has just affected the outside connection of the power take-off shaft of trac..Trailed equipment must be removed when using power take-off shaft, when using trailed equipment, power take-off shaft can not use simultaneously, can'ts eat one's cake and have it.Therefore function is changed loaded down with trivial details, poor compatibility, inefficiency.Although the pendulum-type draw gear can use simultaneously with power take-off shaft, because pendulum-type traction cantilever is long, intensity is relatively poor, is not suitable for pulling of heavy machinery.
The utility model content
The utility model provides a kind of trail device for tractor for the deficiency that prior art exists.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of trail device for tractor, comprise the left fixed mount that is symmetrically set, right fixed mount and drawbar frame, it is characterized in that, described drawbar frame comprises towing plate and adapter plate, the front end of described towing plate is fixedly mounted on the bottom of described left and right fixed by described adapter plate, the rear end of described towing plate is provided with pin-and-hole, is provided with bearing pin in described pin-and-hole.
The beneficial effects of the utility model are: be positioned at the bottom of rear axle housing body due to trail device for tractor, and power take-off shaft is positioned at the top of rear axle housing body, both can take into account and carry out simultaneously relevant operation, are independent of each other, and have improved work efficiency.Be applicable to pulling and towage of various tonnages.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the top of described left and right fixed is provided with the bolt hole that is connected with the rear axle housing body of described trac..
Further, the bottom of described bearing pin is provided with spring cotter.
Adopt the beneficial effect of above-mentioned further scheme to be, facilitate disconnecting of this trailed equipment and trac.; Utilize spring cotter to be convenient to bearing pin is changed and locked.

In Fig. 1～Fig. 4, the represented component names of each label is: 1, left fixed support; 2, right fixed support; 3, bolt hole; 4, pin-and-hole; 5, bearing pin; 6, drawbar frame; 7, spring cotter; 8, power take-off shaft; 9, tractor rear axle housing; 10, towing plate; 11, adapter plate.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As Fig. 1～shown in Figure 3, a kind of trail device for tractor, comprise the left fixed mount 1, right fixed mount 2 and the drawbar frame 6 that are symmetrically set, described drawbar frame 6 comprises towing plate 10 and adapter plate 11, the front end of described towing plate 10 is fixedly mounted on the bottom of described left fixed mount 1, right fixed mount 2 by described adapter plate 11, the rear end of described towing plate 10 is provided with pin-and-hole 4, is provided with bearing pin 5 in described pin-and-hole 4.
The top of described left fixed mount 1, right fixed mount 2 is provided with the bolt hole 3 that is connected with described tractor rear axle housing 9.
The bottom of described bearing pin 5 is provided with spring cotter 7.
Described left and right fixed, drawbar frame 6 adopt cast steel or welded-steel plate construction.
As shown in Figure 4, structural representation after being connected with tractor rear axle housing 9 for the utility model, the top of described tractor rear axle housing 9 is provided with power take-off shaft 8, the bottom of power take-off shaft 8 shown in 6 of described drawbar frames are arranged on, thus avoided power take-off shaft 8 to conflict with the mutual of trailed equipment.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
