Abstract
Description
Technical Field
[0001] This utility model relates to the field of transmission device technology, specifically to a gear shifting transmission device for a peanut harvester. Background Technology
[0002] With the rapid development of agricultural mechanization, peanut harvesters are increasingly widely used, and their performance and efficiency directly affect farmers' income and production efficiency. The gear shifting transmission device, as one of the core components of the peanut harvester, plays a crucial role in enabling switching between different working speeds and modes. However, in actual use, the gear shifting transmission device often faces some technical challenges, especially the connection and transmission between the shifting mechanism and the gearbox.
[0003] Traditional peanut harvester transmissions use a shift cable to connect the shift mechanism to the gearbox's shift shaft for gear switching. While this connection method is structurally simple, it has several shortcomings in practical applications. The coaxiality of the shift cable holder and the gearbox's shift shaft is a key factor affecting shifting force. When the cable holder and the shift shaft are not concentric, the force required for shifting increases significantly, resulting in heavy gears and difficulty in shifting.
[0004] Furthermore, the way the shift cable is secured to the transmission also presents problems. Currently, the shift cable is typically fastened using nuts on both sides of a mounting bracket on the transmission. However, if the mounting bracket is misaligned during manufacturing, or if the cable is misaligned during installation, the angle between the shift cable and the shift shaft will change, affecting the smoothness of shifting. This installation deviation not only increases the difficulty of shifting but may also cause unnecessary wear on the transmission and shifting mechanism, reducing the equipment's lifespan.
[0005] Therefore, a gear shifting transmission device is needed for peanut harvesters to overcome the above problems. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a gear shifting transmission device for a peanut harvester, thereby achieving the objective of resolving the issues raised in the background art.
[0007] To achieve the above objectives, this utility model embodiment adopts the following technical solution: it includes a gearbox body, on which a fixed seat is fixedly connected. The fixed seat has a hole position one and a hole position two for fixing the shift cable. A joint bearing is provided inside the hole position two, and the shift cable is installed inside the hole position two through the joint bearing.
[0008] There are two holes, and each of the two holes contains a spherical bearing.
[0009] The spherical bearing is installed inside hole position two via a rhomboid seat.
[0010] The rhomboid seat is fixedly connected to the two holes by bolts.
[0011] The outer ring of the spherical bearing is fixed inside the diamond-shaped seat, and the shift cable is fixed to the inner ring of the spherical bearing.
[0012] The beneficial effects of this utility model embodiment are as follows:
[0013] The shift cable in this application is fixed inside hole position two using a spherical bearing. When there is a certain deviation in the fixing surface, the spherical bearing can still keep hole position one and hole position two concentric, thus achieving smooth shifting.

[0016] 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.
[0017] See Figure 1 This utility model embodiment discloses a gear shifting transmission device for a peanut harvester, including a gearbox body 1. A fixed seat 2 is fixedly connected to the gearbox body 1. The fixed seat 2 has a hole 4 and a hole 5 for fixing a shift cable 3. A spherical bearing 6 is provided inside the hole 5. The shift cable 3 is installed inside the hole 5 through the spherical bearing 6.
[0018] In this application, the shift cable 3 is fixed inside the second hole 5 by a spherical bearing 6. When there is a certain deviation in the fixing surface, the spherical bearing 6 can still keep the first hole 4 and the second hole 5 concentric, thus achieving smooth shifting.
[0019] As a further explanation of this application:
[0020] There are two holes 2 5, and each hole 2 5 has a joint bearing 6 inside it; there are two holes 2 5 and two holes 1 4, and the two holes 2 5 and the two holes 1 4 correspond one to one; correspondingly, there are two shift cable 3.
[0021] As a further explanation of this application:
[0022] The spherical plain bearing 6 is installed inside the second hole 5 via the rhomboid seat 7. Since there are two holes 5, and the distance between the two holes 5 is small, the two spherical plain bearings 6 are installed through the rhomboid seat 7. The two sides of the rhomboid seat 7 are narrower, while the two sides of the mounting hole are wider. The narrower parts of the rhomboid seat 7 are brought together and installed on the second hole 5. That is, by setting the rhomboid seat 7, the spherical plain bearing 6 can be installed on the two holes 5 with a small distance between them.
[0023] As a further explanation of this application:
[0024] The rhombus-shaped seat 7 is fixedly connected to hole position 2 5 by bolts. The rhombus-shaped seat 7 is provided with mounting holes, and the rhombus-shaped seat 7 is fixed to hole position 2 5 by mounting holes and bolts.
[0025] As a further explanation of this application:
[0026] The outer ring of the spherical bearing 6 is fixed inside the rhomboid seat 7, and the shift cable 3 is fixed at the inner ring of the spherical bearing 6, so that the angle of the shift cable 3 can be changed inside the hole position 2 5 through the spherical bearing 6.
