The limiting lock tieholen of lower perforation, limiting lock tieholen and the limiting locking chamber upper and lower corresponding are arranged.
Further, the two sides in the limit telescopic slot are equipped with limit telescopic sliding slot, and the two sides of position limit arm are equipped with limit
Flexible sliding block, limit telescopic sliding block are slidably mounted in limit telescopic sliding slot.
Further, the plug-in connection includes anticreep spring, and anticreep spring, which is connected to, is followed by cavity upper end and bolt
Between upper end.
Further, the bolt is equipped with the anticreep hole of lateral direction penetrating, and anticreep hole is arranged under the locking nut
Side.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, have the following advantages that in above-mentioned technical proposal or the utility model has the advantages that
Tractor can be effectively prevented, phenomenon of turning on one's side occurs in the process of backing up.
Detailed description of the invention
Fig. 1 is the structure schematic top plan view of the utility model embodiment；
Fig. 2 is the structure schematic rear view of the utility model embodiment；
In figure: 1, traction body；2, position limit arm；3, bail；4, limit telescopic slot；5, it is followed by cavity；6, limiting locking chamber；
7, limiting lock tieholen；8, position-limitting pin；9, bolt；10, anticreep spring；11, locking nut；12, anticreep hole.
Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Utility model is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.The utility model
It is omitted to known assemblies and well-known technique description, to avoid the utility model is unnecessarily limiting.
As illustrated in fig. 1 and 2, a kind of limit traction card device for preventing tractor from turning on one's side, including traction mechanism and grafting machine
Structure, the front end of traction mechanism with the rear end of tractor for connecting, and the rear end of traction mechanism with wagon box for connecting；The grafting
Mechanism is used to lock traction mechanism and wagon box.
The traction mechanism includes traction body 1 and position limit arm 2.Traction body 1 is whole to use chevron shaped structure, traction body 1
Front end is equipped with bail 3, and bail 3 with the rear interfacing part of the rear end of tractor for connecting.The rear end of traction body 1 is equipped with and is followed by
Cavity 5 is followed by cavity 5 for the wagon box buttcover plate to slotting rear wagon box；Cavity 5 is followed by equipped with spliced eye up and down.
The two sides of the traction body 1 are equipped with limit telescopic slot 4, and the two sides in limit telescopic slot 4 are equipped with limit telescopic sliding slot；Limit telescopic
Limiting locking chamber 6 up and down is equipped at intervals on slot 4.The position limit arm 2 inside and outside can adjust flexible setting in the limit
In telescopic chute 4；The two sides of position limit arm 2 are equipped with limit telescopic sliding block, and it is sliding that limit telescopic sliding block is slidably mounted on limit telescopic
In slot；Position limit arm 2 is equipped with limiting lock tieholen 7 up and down, limiting lock tieholen 7 and 6 upper and lower corresponding of limiting locking chamber
Setting.It is moved backward according to tractor and limits corner angle, adjusted the extended length of 2 relative limit telescopic chute 4 of position limit arm, then use
Position limit arm 2 and limit telescopic slot 4 are connected and fixed by position-limitting pin 8.When tractor reversing is turned, rear-wheel touches position limit arm 2
Afterwards, it will be unable to continue to tune up to turn angle；So as to prevent tractor from rollover event occurs because corner angle of moving backward is excessive.
The plug-in connection includes bolt 9, anticreep spring 10 and locking nut 11.Bolt 9 is followed by cavity 5 described in being plugged on
Spliced eye in, the traction body 1 is connected with wagon box front end.The anticreep spring 10, which is connected to, to be followed by 5 upper end of cavity and inserts
Between the upper end of pin 9,10 one side of anticreep spring can prevent the unexpected loss of bolt 9 when not in use；It on the other hand can be with
Play the role of antivibration, prevents the loosening of bolt 9 when in use.The locking nut 11 matches the lower part for being screwed onto bolt 9；Bolt
9 lower end is equipped with the anticreep hole 12 of lateral direction penetrating, and iron wire can be used across anticreep hole 12, prevent the accident of locking nut 11 de-
It falls.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
