Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
The device comprises a base, a support, a gasket, a spring, a nut, a bolt, a guide rod, a lock pin and a spring, wherein the base comprises 1-an upper joint, 2-a barrel, 3-a lower joint, 4-the spring, 5-the nut, 6-the guide hole, 7-the guide rod, 8-the lock pin and 9-the gasket.
Detailed Description
For a better understanding of the present invention, the following description is given in conjunction with the accompanying drawings and examples.
It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in figure 1, a flexible pull rod of rear-mounted three point linkage of tractor for oil field, a serial communication port, including top connection 1, barrel 2 and lower clutch 3, top connection and lower clutch are the body of rod that one end is the ring structure, the last pin joint that the ring one end of top connection and the rear three point of tractor hung meets, body of rod one end stretches into barrel one side and links to each other with the barrel, the ring one end of lower clutch meets with the last pin joint of weeding equipment, body of rod one end stretches into barrel opposite side and barrel movable connection, be equipped with spring 4 in the barrel, the both ends of spring respectively with last, the lower clutch links to each other.
The body of rod one end of top connection is equipped with the external screw thread, and barrel one side inner wall is equipped with the internal thread, and with external screw thread phase-match, top connection and barrel one side threaded connection to lock through nut 5. The length of the whole pull rod can be adjusted by rotating the upper joint forwards and backwards, and then the distance between the rear weeding equipment of the tractor and the ground is adjusted.
The other side of the cylinder body is provided with guide holes 6 which are vertically symmetrical, the other end of the lower joint is provided with a through hole, the cylinder body is connected with the lower joint through a guide rod 7, and the guide rod moves along the guide holes. The guide rod is of a T-shaped rod structure, and the small end of the guide rod penetrates through the guide hole and is limited through the lock pin 8.
A gasket 9 is arranged between the other end of the upper joint and the spring.
When the flexible pull rod is used, the upper joint of the flexible pull rod is connected with an upper hinge point of a three-point suspension arranged at the rear of the tractor, and the lower joint is connected with an upper hinge point of the weeding device. The adjustment of the distance between the rear weeding equipment of the tractor and the ground can be adjusted through the threads of the upper joint of the flexible pull rod, the distance is adjusted, and the nut is screwed. When the shaping wheel of the weeding equipment meets the raised ground or stones in the well site operation, the upward resisting force is generated, and the resisting force is released through the spring in the flexible pull rod combined by the upper pull rod of the three-point suspension device and the upper hinge point of the weeding equipment.
The weeding equipment generates upward pressure to be transmitted to one end of the ring of the lower joint of the flexible pull rod to push and compress the spring in the cylinder body, and the whole pull rod is shortened to consume and release the collision force. Meanwhile, the guide rod on the lower joint moves from one end of the guide hole to the other end of the guide hole. When the weeding equipment crosses the obstacle, the spring in the flexible pull rod cylinder body restores to push the guide rod of the lower joint to restore the original position, and large shearing force is avoided.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
