Embodiment Construction
[0014] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0015] The fine-tuning mechanism of the gear control lever of the tractor with mechanical transmission includes internal and external threads for adjusting the length of the lever along the joystick 1 along the length of the lever. The part where the internal thread is set is notched along the length of the lever. Table 3, two bolts fixed table 3 is equipped with clamping bolt 4 for clamping joystick 1 and is provided with nut, and the part that sets external thread also cooperates with locking nut 2.
[0016] When it is necessary to adjust the length of the rod, loosen the locking nut 2, the clamping bolt 3 and the nut, adjust the matching length of the inner and outer threads of the joystick, and tighten the clamping bolt 3 and the nut after they are in place, and friction will occur after clamping Firmly fix the inner and outer joysticks, and fi...

The invention belongs to a gear operating lever of a mechanical transmission tractor, which is provided with a fine adjustment mechanism of gear operation of the mechanical transmission tractor, and solves the problem that the gear operating lever of the existing mechanical transmission tractor has complex installation and easy looseness. The fine adjustment mechanism of the mechanical transmission tractor comprises an internal thread and an external thread which adjust the lever length along the length direction of the operating lever, and is characterized in that the part provided with the internal thread is provided with a notch along the length of the lever; the upper part and the lower part of the notch are respectively welded with a bolt fixed station; the bolt fixed stations are provided with clamp bolts and nuts, wherein the clamp bolts are used for clamping the operating lever; and the part provided with the external thread is matched with a locknut. The fine adjustment mechanism of the invention has the following beneficial effects: 1. lever length can be conveniently adjusted, and the mechanism has convenient arrangement and installation; 2. the service life is long, and the looseness of the operating lever can not be generated; and 3. the frictional force generated by the clamp force and the nut lock act together to clamp and fix the operating lever more firmly, thus solving the problem of looseness of the gear operating lever.
Description
technical field [0001] The invention belongs to a gear position control lever of a mechanical transmission tractor, and the control lever has a fine adjustment mechanism for the gear position control of a mechanical transmission tractor. Background technique [0002] The gear lever of a mechanical transmission tractor not only needs to move in translation along the length of the rod, but also needs to rotate along its own axis, and at the same time needs to be fine-tuned along the length of the rod. And the domestic existing mechanical transmission tractor gear control lever generally adopts bolt and nut structure to adjust the lever length along the lever length direction, after adjusting, adopt nut locking, then match the tight elastic pin to fix. The disadvantage of this structure is that holes need to be drilled on site to tighten the elastic pins, and the installation is cumbersome; in addition, the elastic pins will be deformed and cut off after long-term use, which ma...
