Abstract
The utility model discloses a multi-degree freedom connection device, belongs to a steering connection device of farm machinery, and aims at providing a connection device used for connecting farm mechanical power and field operation machine tools or parts to meet the requirement of high maneuverability of farm machinery operated in a mountainous area with complex terrain. The multi-degree freedom connection device comprises a left connection frame (1), a middle connection frame (2), a right connection frame (5), and a second bolt (6), wherein the left connection frame (1) is provided with a hinged hole (9), the middle connection frame (2) is hinged with the left connection frame, the right connection frame (5) is hinged with the middle connection frame through a first bolt (7), and the second bolt (6) is arranged on the right connection frame. According to the multi-degree freedom connection device, high-maneuverability requirements, such as horizontal deflection, longitudinal bumping overturning and horizontal torsion are meet between a front vehicle body and a rear vehicle body when the farm machinery walks or operates on a winding and scraggly road or land. The multi-degree freedom connection device has the advantages of being small in radius of turning circle, mobile, flexible, and the like, and is used for connecting the front vehicle body and the rear vehicle body of a farm vehicle.
Description
Technical field
The utility model relates to a kind of steering linkage, relates in particular to a kind of steering linkage for car body before and after connecting.
Background technology:As everyone knows, the operating environment of the farm machineries such as tractor, cultivated plough machine, sower, grain header is more complicated, abominable all, because road or the arable land zigzag, rough and uneven in surface in mountain area, the steering linkage of car body must have the requirement that multi-direction rotational freedom could satisfy the farm machinery high maneuverability before and after therefore being used for connecting.Yet the forward and backward car body of present above-mentioned farm machinery all is directly to connect by bearing pin usually, only has one or two degree of freedom, can not satisfy the needs of mountainous rural area complex-terrain work production far away.
Summary of the invention:For the defects that exists in the prior art, the utility model aims to provide a kind of multiple degrees of freedom jockey for connecting farm machinery power and farm work facility or parts; To satisfy agricultural machinery in the required high maneuverability requirement of mountain area complex-terrain work production.
To achieve these goals, the utility model is by the following technical solutions: it comprises left link with hinge hole, with the hinged middle link of this left link, by the hinged right link of the first bolt and this centre link, be located at the second bolt on this right link.
Respectively be fixed with a bolt in the both sides that middle link is positioned at the first bolt, respectively be provided with a kidney slot in the both sides that right link is positioned at the first bolt, each bolt is inserted in respectively in the corresponding kidney slot; Be provided with the spring that is pressed on by nut on the right link at the first bolt.
Compared with the prior art, the utility model has been owing to adopted technique scheme, increased to comprise hinged successively left link, middle link and right link between forward and backward car body; Therefore when farm machinery at zigzag, scraggly road or when ploughing walking or operation, can realize deflection between the forward and backward car body, pitch upset and about the high maneuverability such as reverse and move; Have the advantages such as radius of turn is little, maneuverability.
Use this device, can make Work machine have within the specific limits the adaptivity of deformation everywhere, thereby can reduce broadcast leakage, the phenomenon such as balk, make the agricultural machinery can steady operation when operation.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1;
A among Fig. 3 Fig. 2-A cutaway view.
Among the figure: link 2 bearing pins 3 bolts 4 right link 5 second bolts 6 first bolts 7 springs 8 hinge holes 9 kidney slots 10 in the middle of the left link 1
Embodiment:The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Shown in Fig. 1～3: left link 1 is provided with the hinge hole 9 that can be connected with the car body (not shown), middle link 2 is hinged by bearing pin 3 and this left link, right link 5 is hinged by the first bolt 7 and middle link 2, is fixed with the second bolt 6 on this right link.
The amplitude of reversing in order to limit right link about 5, respectively be provided with a bolt 4 that is fixed on the middle link 2 in the both sides of the first bolt 7, position corresponding to each bolt 4 on right link 5 is provided with kidney slot 10, and each bolt 4 is inserted in respectively in the corresponding kidney slot 10.In order to cushion, be provided with spring 8 at the first bolt 7, this spring is pressed on the right link 5 by nut.
Claims (3)
1. multiple degrees of freedom jockey is characterized in that: comprise left link (1) with hinge hole (9), with hinged middle the link (2) of this left link, by the hinged right link (5) of the first bolt (7) and this centre link, be located at the second bolt (6) on this right link.
2. multiple degrees of freedom jockey according to claim 1, it is characterized in that: respectively be fixed with a bolt (4) in the both sides that middle link (2) is positioned at the first bolt (7), respectively be provided with a kidney slot (10) in the both sides that right link (5) is positioned at the first bolt (7), each bolt (4) is inserted in respectively in the corresponding kidney slot (10).
3. multiple degrees of freedom jockey according to claim 1 and 2 is characterized in that: be provided with the spring (8) that is pressed on by nut on the right link (5) at the first bolt (7).
