Another of the utility model is designed to provide a kind of tractor with above-mentioned towing mechanism.
To achieve the goals above, the technical solution of the utility model provides a kind of towing mechanism, is used for tractor, packet
Include: connection main body, connection main body are equipped with lockhole；Lock tongue can move in lockhole and along lockhole；Rotation regulating mechanism, can
Rotation is set in connection main body and connect with lock tongue；Bracket, connection main body are movably arranged on bracket, and bracket is arranged above and below
Multiple limit holes, lock tongue can be inserted into limit hole so that connection main body is fixed on bracket；Connector is pulled, is fixed with main body is connect
Connection, wherein drive lock tongue to move along lockhole when rotation regulating mechanism rotates, so that lock tongue is inserted into limit hole or out of limit hole
It removes.
The towing mechanism that this programme provides can be such that lock tongue moves along lockhole, so that lock tongue by rotating rotation regulating mechanism
Insertion limit hole is removed out of limit hole, and the height of connection main body, Jin Erneng can be adjusted when lock tongue is removed out of limit hole
Adjust the height for pulling connector.Lock tongue movement is driven to keep the adjusting for pulling connector height more square by rotation regulating mechanism
Just.
Specifically, connection main body is equipped with lockhole, and lock tongue is set in lockhole and can move along lockhole, to realize lock tongue
Relative to the flexible of connection main body.Bracket, which is arranged above and below, multiple limit holes, and lock tongue can be inserted into when stretching out relative to connection main body
Limit hole is so that connection main body is fixed on bracket.When the limit hole of lock tongue insertion different height, it is able to achieve connection main body and exists
Fixation on different height, with the adjusting to lock catch connector height.
Rotation regulating mechanism is rotatably arranged in connection main body and connect with lock tongue, when rotation regulating mechanism rotates, energy
Enough lock tongue is driven to move along lockhole, even if lock tongue is flexible relative to connection main body, so that lock tongue insertion limit hole or from limit hole
Interior removal.When needing adjusting to pull the height of connector, rotation regulating mechanism is rotated so that lock tongue is removed out of limit hole.With

Specific embodiment
In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have
The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen
The feature in embodiment and embodiment please can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other than the one described here other modes, therefore, the protection scope of the utility model is simultaneously
It is not limited by the specific embodiments disclosed below.
Some embodiments according to the present utility model are described referring to Fig. 1 to Fig. 4.
As shown in Figures 1 to 4, the embodiment of the utility model first aspect provides a kind of towing mechanism, for drawing
Machine, it is main include connection main body 10, be fixed in connection main body 10 pull connector 50 and with connect what main body 10 cooperated
Bracket 40, connection main body 10 are fixed on bracket 40.
Specifically, connection main body 10 is equipped with lockhole 101；Lock tongue 20 is set in lockhole 101 and can move along lockhole 101
(such as lockhole 101 has certain length, such as 50mm, lock tongue 20 is set in lockhole 101 rear lockhole 101 and leads to lock tongue 20
It to effect, move lock tongue 20 can only along lockhole 101)；Rotation regulating mechanism 30, which is set in connection main body 10, (such as passes through shaft
Connection) and connect with lock tongue 20；Connection main body 10 is movably arranged on bracket 40 that (such as whole can be embedded in of connection main body 10 is propped up
Can move up and down in frame 40 and along bracket 40), bracket 40 is arranged above and below multiple limit holes 401, and lock tongue 20 can be inserted into limit hole 401
So that connection main body 10 is fixed on bracket 40；It pulls connector 50 and is fixedly connected with main body 10 is connect, wherein rotation adjusting machine
Lock tongue 20 is driven to move along lockhole 101 when structure 30 rotates, rotation regulating mechanism 30 can make lock tongue when rotating along the first direction of rotation
20 insertion limit holes 401, rotation regulating mechanism 30 can be from limits when rotating along second direction of rotation opposite with the first direction of rotation
Position removes in hole 401.
The towing mechanism that this programme provides can be such that lock tongue 20 moves along lockhole 101 by rotation rotation regulating mechanism 30,
So that lock tongue 20 is inserted into limit hole 401 or removes out of limit hole 401, can be adjusted when lock tongue 20 is removed out of limit hole 401
The height of main body 10 is connected, and then is adjustable the height for pulling connector 50.Lock tongue 20 is driven to move by rotation regulating mechanism 30
It is dynamic to keep the adjusting for pulling 50 height of connector more convenient.
Specifically, connection main body 10 is equipped with lockhole 101, and lock tongue 20 is set in lockhole 101 and can move along lockhole 101
It is dynamic, to realize lock tongue 20 relative to the flexible of connection main body 10.Bracket 40, which is arranged above and below, multiple limit holes 401,20 phase of lock tongue
Limit hole 401 can be inserted into when stretching out for connection main body 10 so that connection main body 10 is fixed on bracket 40.When in mounting agricultural machinery
It needs to adjust the height for pulling connector 50 when tool, rotates rotation regulating mechanism 30 along the first direction of rotation, so that lock
The opposite connection main body 10 of tongue 20 is shunk, and lock tongue 20 is removed out of limit hole 401, at this time by making to connect main body 10 with respect to bracket 40
Move up and down to adjust and pull the height of connector 50, until the height for pulling connector 50 meet mounting demand and lock tongue 20 with
It when limit hole 401 is aligned, rotates rotation regulating mechanism 30 along the second direction of rotation, makes the opposite connection main body 10 of lock tongue 20
It stretches out and is inserted into limit hole 401.Reach the adjusting to lock catch connector height at this time.
The flexible of lock tongue 20,30 rotary course of rotation regulating mechanism are adjusted by rotation rotation regulating mechanism 30 in this programme
Middle the space occupied is smaller, convenient for keeping towing mechanism integrally more compact, keeps the applicability of towing mechanism more preferable.
It is relatively fixed side in the above embodiment, it is preferable that pulling connector 50 with connecting side and with connecting side,
The connecting side of connector 50 is pulled with equipped with U-shaped hook 501, the affixed side for pulling connector 50 connects (example with main body 10 is connect
Such as it is bolted), rotation regulating mechanism 30 is located at the other side for pulling connector 50 relative to connection main body 10.At this point,
Connection main body 10 does not influence to pull the connection of connector 50 Yu other towing mechanisms, in order to improve the connection for pulling connector 50
Efficiency.Simultaneously, additionally it is possible to reduce and connect 10 quilt of main body during the U-shaped hook 501 for pulling connector 50 is mounted with agricultural machinery and implement
A possibility that colliding with, convenient for improving the reliability of towing mechanism.It is also pointed out that rotation regulating mechanism 30, which is located at, pulls connection
The other side of the part 50 relative to connection main body 10, can also reduce a possibility that rotation regulating mechanism 30 is accidentally touched, meanwhile, it can be with
Understand, be just convenient for rotating rotation regulating mechanism 30 when only tractor is static, be convenient for operator's standard operation, reduces to generate and drag
Operator rotates a possibility that uses lack of standardization such as rotation regulating mechanism 30 when machine drawing is advanced, and uses convenient for raising towing mechanism
Safety.
