Description

Technical Field

[0001] This utility model relates to the field of connecting traction structure technology, and in particular to a connecting traction structure for agricultural machinery. Background Technology

[0002] In the operation of agricultural machinery, the tractor unit typically pulls the trailer. The connection between the tractor unit and the trailer is achieved by a pin passing through the tractor frame installed on both the tractor unit and the trailer. However, a power connection pipe is usually connected between the tractor unit and the trailer for power transmission. But the tractor frame installed on the tractor unit and the trailer cannot properly limit the position of the power connection pipe. As a result, during operation, the power connection pipe is prone to breakage due to random swaying, which is a defect. Utility Model Content

[0003] This utility model relates to a connecting traction structure for agricultural machinery, which solves the problem that the traction frame installed on the current tractor and trailer cannot achieve the corresponding position limit for the power connection pipe, resulting in the power connection pipe being easily clamped and damaged during operation due to the random shaking of the power connection pipe position.

[0004] This utility model provides a connecting and traction structure for agricultural machinery, specifically including: a mating connecting block, the mating connecting block having a square block structure, a limiting annular block being provided on the top of the mating connecting block, and an extension block having a circular block structure being provided at the center of the bottom of the limiting annular block; a spring connector being fixedly installed at the axial center of the bottom end face of the extension block, and the bottom end of the spring connector being welded to the top face of the mating connecting block; a snap-fit ​​opening communicating with the inner circumference of the front side of the limiting annular block is provided, and the upper and lower sides of the snap-fit ​​opening have semi-circular structures.

[0005] Furthermore, a U-shaped rotating connecting block is fixedly installed on the right end face of the mating connecting block, and the rotating connecting block has a shaft hole that passes through its front and rear faces relative to the axial center of its semi-circular structure; there are two sets of mating connecting blocks, and the two rotating connecting blocks of the two sets of mating connecting blocks fit together, and the two shaft holes are connected by a rotating shaft.

[0006] Furthermore, it also includes a traction mating block, which has a U-shaped block structure. The traction mating block has a traction mating groove that runs through its front end, rear end face and left end face. The traction mating groove has a U-shaped groove structure. The traction mating block has a traction mounting hole that runs through its top end face and bottom end face at the axial center of its semi-circular structure. The traction mounting hole also runs through and connects to the traction mating groove.

[0007] Furthermore, a T-shaped shaft is fixedly installed at the center of the right end face of the traction mating block; a T-shaped groove is opened at the center of the left end face of the mating connecting block; there are two sets of traction mating blocks, which are distributed symmetrically from left to right, and the T-shaped shafts of the two sets of traction mating blocks are rotatably connected to the T-shaped grooves of the two sets of mating connecting blocks respectively.

[0008] This utility model provides a connecting and traction structure for agricultural machinery, which has the following beneficial effects:

[0009] This utility model utilizes two sets of limiting ring blocks. After the power connection pipe used for power transmission between the tractor and trailer is installed, the power connection pipe can be clamped into the limiting ring block, limiting the power connection pipe in a certain position area. This helps prevent the power connection pipe from being clamped and damaged during subsequent towing and transportation. Furthermore, this application ensures that while limiting the power connection pipe in a certain position area, it does not create a rigid limitation on the power connection pipe through the small-distance stretching and small-angle bending of the spring connector. This allows the limiting ring block to move a small distance in the direction of the stretching of the power connection pipe when it is accidentally pulled by an external object, thus minimizing the risk of damage to the power connection pipe.

[0010] This utility model achieves fixed installation by using two sets of traction connecting blocks, which are respectively attached to the traction end of the tractor and the traction end of the trailer. Furthermore, this application uses a T-shaped shaft and T-slot for rotatable installation. Depending on the traction installation angle, the angle of the traction connecting blocks can be adjusted by rotating along the connecting blocks to meet installation requirements. The vertically rotatable installation connection of the two sets of connecting blocks facilitates adjustment of the angle when the vertical angle of the traction end of the tractor and the traction end of the trailer fluctuates, ensuring that no hard bending occurs and meeting traction and transportation needs.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Example: Please refer to Figures 1 to 4 :

[0025] This utility model proposes a connecting and traction structure for agricultural machinery, comprising: a mating connecting block 2, which is a square block structure; a limiting annular block 4 is provided on the top of the mating connecting block 2; an extension block 403, which is a circular block structure, is provided at the center of the bottom of the limiting annular block 4; a spring connector 402 is fixedly installed at the axial center of the bottom end face of the extension block 403, and the bottom end of the spring connector 402 is welded to the top face of the mating connecting block 2; and a section is provided on the lower side of the front of the limiting annular block 4. A snap-fit ​​opening 401 is connected to its inner circumferential surface. Both the upper and lower sides of the snap-fit ​​opening 401 are semi-circular structures. Therefore, when the power connection pipe is snapped into the limiting ring block 4 through the snap-fit ​​opening 401, the open end of the snap-fit ​​opening 401 will not scratch the power connection pipe. A rotating connecting block 201 with a U-shaped block structure is fixedly installed on the right end face of the connecting block 2. The rotating connecting block 201 has a shaft hole 20 through its front and rear ends at the axial center of its semi-circular structure. 2; The connecting block 2 consists of two sets, with the two rotating connecting blocks 201 of the two sets fitting together and connected by a rotating shaft 3 at the two shaft holes 202; it also includes a traction connecting block 1, which has a U-shaped block structure. The traction connecting block 1 has a traction connecting groove 101 that runs through its front end, rear end face, and left end face. The traction connecting groove 101 has a U-shaped groove structure; a through-hole is formed at the axial center of the traction connecting block 1 relative to its semi-circular structure. The top and bottom surfaces of the traction mounting holes 102 are connected to the traction mating groove 101. A T-shaped shaft 103 is fixedly installed at the center of the right end face of the traction mating block 1. A T-shaped groove 203 is opened at the center of the left end face of the mating connecting block 2. There are two sets of traction mating blocks 1, which are symmetrically distributed from left to right. The T-shaped shafts 103 of the two sets of traction mating blocks 1 are rotatably connected to the T-shaped grooves 203 of the two sets of mating connecting blocks 2.

[0026] The working principle of this embodiment:

[0027] The traction end of the vehicle head is inserted into the traction groove 101 of a set of traction mating blocks 1 and is fixedly connected by a pin that passes through the traction mounting hole 102 and the traction hole of the traction end of the vehicle head; while the traction end of the trailer is inserted into the traction groove 101 of another set of traction mating blocks 1 and is also fixedly connected by a pin that passes through the traction mounting hole 102 and the traction hole of the trailer end. Furthermore, the traction mating block 1 and the mating connecting block 2 are rotatably connected by a T-shaped shaft 103 and a T-shaped groove 203, so the angle position of the traction mating block 1 can be adjusted by rotation according to different traction mounting angles.

[0028] During towing and transportation, when the traction end of the tractor and the traction end of the trailer fluctuate vertically, the two sets of mating connecting blocks 2 will adjust the angle vertically through the rotational connection between the rotating shaft 3 and the shaft hole 202, ensuring that they will not bend rigidly.

[0029] After the power connection pipe for power transmission between the tractor and the trailer is connected and installed, the power connection pipe can be inserted into the limiting ring block 4 through the snap-fit ​​opening 401. This limits the power connection pipe in a certain position area, ensuring that it will not swing to other positions during subsequent traction and transportation, thus preventing it from being pinched and damaged. Furthermore, the spring connector 402 allows the power connection pipe to move with the traction and transportation. Through the small-distance stretching and small-angle bending of the spring connector 402, it ensures that while limiting the power connection pipe in a certain position area, it will not cause a rigid limit. This is beneficial because if the power connection pipe is accidentally pulled by an external object, the stretching and bending of the spring connector 402 will allow the limiting ring block 4 to move a small distance in the direction of the pull, thus minimizing the risk of damage to the power connection pipe.
