Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery equipment technology, specifically to a gear shifting transmission device for a peanut harvester. Background Technology
[0002] The harvester's gears are shifted by a shift mechanism connected to the gearbox shift shaft via a shift cable.
[0003] The shift cable holder and the gearbox shaft determine the shifting force. When the cable holder and the gearbox shaft are not concentric, the gears will be heavy and difficult to shift.
[0004] Existing harvester gear shifting devices, such as Figure 1 As shown, the shift cable and the connecting shaft are connected and positioned by a fixed support. The shift cable is fixed to the mounting bracket on the gearbox by two nuts on both sides of the cable. The fixed support has a U-shaped groove corresponding to the position of the nuts. When the positioning plate on the gearbox is not concentric with the mounting plate during installation, the shift cable will be misaligned, which will cause difficulty in shifting, affect the normal use of the equipment, and in severe cases, affect the service life of the equipment.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0022] like Figure 2-3As shown, the peanut harvester gear shifting transmission device of this embodiment includes a shift cable 1, a connecting shaft 2, and a fixed support 3. The fixed support 3 includes a base plate 4. One end of the base plate 4 is provided with a positioning plate 5 connected to the engine box, and the other end is provided with a mounting plate 6. The mounting plate 6 is provided with an adjusting seat 7 for installing the shift cable 1. The design of the adjusting seat 7 can ensure that the shift cable 1 and the connecting shaft 2 remain concentric. Compared with the conventional nut fixing method, the adjusting seat 7 can compensate for the axial deviation between the shift cable 1 and the connecting shaft 2 during gear shifting, ensuring the smooth operation of gear shifting.
[0023] The adjusting seat 7 includes a spherical bearing 8. The outer side of the spherical bearing 8 is provided with an extension plate 9 connected to the mounting plate 6. The interior of the spherical bearing 8 is provided with a connecting sleeve 10 for installing the shift cable 1. The spherical bearing 8 includes a seat ring 11, an inner ring 12 and a self-lubricating layer 13. The self-lubricating layer 13 is made of polytetrafluoroethylene fabric. The connecting sleeve 10 passes through the interior of the inner ring 12 and is fixedly connected to the inner ring 12. The extension plate 9 is connected to the outer wall of the seat ring 11. There are two extension plates 9, which are symmetrically distributed about the center line of the seat ring 11. The two extension plates 9 and the seat ring 11 form a rhomboid structure, which fixes the adjusting seat 7 on the mounting plate 6.
[0024] like Figure 4 As shown, the shift cable 1 includes a drive rod 14 and a transmission rod 15. The front end of the connecting sleeve 10 is provided with a plug sleeve 16 for installing the drive rod 14, and the end is fixedly connected to the transmission rod 15. The shift cable 1 is divided into two parts, wherein the transmission rod 15 is located between the connecting sleeve 10 and the connecting stop shaft 2, and the drive rod 14 is installed in the plug sleeve 16. During the transmission process, after the connecting sleeve 10 is connected to the inner ring 12, axial gap compensation is performed during transmission to ensure that the shift cable 1 and the connecting stop shaft 2 are concentrically distributed, thus ensuring the smooth operation of shifting.
[0025] The positioning plate 5 is provided with a clearance hole 17 corresponding to the position of the connecting shaft 2. The clearance hole 17 is provided with threaded holes 18 on both sides for mounting the positioning plate 5. The connection between the positioning plate 5 and the engine box is completed through the threaded holes 18. The mounting plate 6 is provided with a through hole for mounting the adjusting seat 7.
[0026] like Figure 5 As shown, the positioning plate 5, the base plate 4, and the mounting plate 6 are integrally formed and distributed in a U-shape, which can ensure the coaxial distribution of the positioning plate 5 and the mounting plate 6 during manufacturing and reduce the skewness of the shift cable 1 and the connecting shaft 2.
