Description

Technical Field

[0001] This invention relates to the field of V-belt technology, specifically to a double-sided toothed V-belt for harvesters. Background Technology

[0002] The harvester double-sided toothed V-belt is a specially designed transmission belt used in agricultural machinery, especially in harvesters. This V-belt is characterized by its double-sided toothed design, allowing it to transmit power in both directions, making it suitable for complex transmission systems.

[0003] Because each machine's transmission system is designed differently, the length of the V-belt connecting the transmission system also varies. To ensure that the V-belt remains taut after installation in the transmission system, a tensioning pulley is often added. When installing the V-belt, first loosen the tensioning pulley, then install the V-belt in various positions on the transmission system, and maintain the V-belt's tension by moving and locking the tensioning pulley.

[0004] While this allows for the installation of V-belts onto the drive system, it still presents the following drawbacks: In addition to fulfilling the original transmission function, the drive system requires an extra tensioner to support the V-belt installation. This not only increases the additional installation space required for the drive system but also raises its manufacturing cost. Summary of the Invention

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 2-7 As shown, a harvester double-sided toothed V-belt includes a V-belt body 2. In this embodiment, the V-belt body 2 has a strip-shaped structure. A plurality of first protruding teeth 21 are disposed on the upper surface of the V-belt body 2, and a plurality of second protruding teeth 22 are disposed on the lower surface of the V-belt body 2. Each first protruding tooth 21 and each second protruding tooth 22 is perpendicular to the direction of movement of the V-belt body 2. A mounting housing 1 is connected to both ends of the strip-shaped structure of the V-belt body 2. A first adjustment mechanism and a second adjustment mechanism are respectively disposed at both ends of the mounting housing 1, both used to adjust the distance between the two ends of the V-belt body 2. A first locking mechanism is disposed on the first adjustment mechanism to connect or disconnect the V-belt body 2 from the first adjustment mechanism. A second locking mechanism is disposed on the second adjustment mechanism to connect or disconnect the V-belt body 2 from the second adjustment mechanism. In this embodiment, after the V-belt body 2 is tightened and installed, the excess part of the V-belt body 2 is cut off and connected with a connector, and then the mounting housing 1 is removed. At this time, the V-belt body 2 is directly in a taut state, which replaces the design of adding a tensioning wheel to the harvester transmission system in the prior art. This not only saves the manufacturing cost of the transmission system, but also makes this embodiment more applicable.

[0020] In this embodiment, the V-belt body 2 includes a plurality of parallel tension cords 23 arranged inside the V-belt body 2, each tension cord 23 is parallel to the first convex tooth 21, and the tension cord 23 is made of aramid fiber wire material. Such a design enhances the strength of the V-belt body 2, makes the V-belt body 2 less prone to deformation, and prolongs the service life of the V-belt body 2.

[0021] The first adjustment mechanism in this embodiment includes a sliding structure, which is used to control the movement of the V-belt body 2 relative to the mounting housing 1. The first self-locking structure is arranged on the sliding structure, and is used to maintain the sliding position of the V-belt body 2 relative to the mounting housing 1 after adjustment is completed. The first adjustment mechanism and the second adjustment mechanism have the same structure. In this embodiment, the tensioned installation of the V-belt body 2 is realized by controlling the movement of the V-belt body 2 relative to the mounting body. Wherein, the arrangement of two adjustment mechanisms can realize adjustment of both ends of the V-belt body 2, so that the V-belt body 2 at both ends can be connected at the position near the center of the mounting housing 1, which facilitates cutting, connecting and fixing both ends of the V-belt body 2.

[0022] The sliding structure in this embodiment includes a first adjustment gear 61 and a second adjustment gear 62, both of which are rotatably connected to the mounting housing 1. The first adjustment gear 61 and the second adjustment gear 62 are arranged on both sides close to the V-belt body 2, and both of them mesh with the second convex teeth 22. A sliding rack 7 is also meshed with the first adjustment gear 61, a first sliding rail 8 is fixedly arranged in the mounting housing 1, a first sliding groove 81 is arranged in the first sliding rail 8, the cross section of the first sliding groove 81 is of a "convex" shape structure, and the sliding rack 7 is slidably connected with the first sliding groove 81. In this embodiment, the V-belt body 2 is moved by moving the sliding rack 7, which avoids skewing of the V-belt body 2 caused by directly moving the V-belt body 2. In this embodiment, the first sliding groove 81 with a "convex" shape structure provides a stable connection mode, and the sliding function is realized more stably and reliably.

[0023] In this embodiment, the first locking mechanism includes a first pressure roller 41 and a second pressure roller 42, which are disposed on both sides of the V-belt body 2. Both the first pressure roller 41 and the second pressure roller 42 abut against the V-belt body 2 to ensure that the V-belt body 2 is fully engaged with the first adjusting gear 61 and the second adjusting gear 62, ensuring greater stability when the first adjusting gear 61 and the second adjusting gear 62 drive the V-belt body 2. The vertical projection plane of the central axis of the first pressure roller 41 coincides with the vertical projection plane of the central axis of the first adjusting gear 61, and the vertical projection plane of the central axis of the second pressure roller 42 coincides with the vertical projection plane of the central axis of the second adjusting gear 62. A synchronization structure is disposed within the mounting housing 1 to synchronize the first pressure roller 41 and the second pressure roller 42 away from or towards the V-belt body 2. A second self-locking structure is disposed on the synchronization structure to maintain the distance between the synchronization structure and the V-belt body 2 after adjustment. The first locking mechanism and the second locking mechanism have the same structure. In this embodiment, a synchronization structure is added between the first pressure roller 41 and the second pressure roller 42 to make the first pressure roller 41 and the second pressure roller 42 move synchronously, so that the movement of the V-belt body 2 is not easily skewed and affects the connection of the V-belt bodies 2 at both ends.

[0024] In this embodiment, the first self-locking structure includes a locking bolt 171 and a first threaded hole 172 on the mounting housing 1, which is threadedly connected to the locking bolt 171. A limiting hole 71 is located on the sliding rack 7 near the first threaded hole 172, and a first sliding hole 711 is located on the wall of the limiting hole 71 near the first threaded hole 172. The locking bolt 171 is slidably connected to the first sliding hole 711, and the first limiting bolt 1711 is located inside the limiting hole 71, and is fixedly connected to the locking bolt 171. The design of the locking bolt 171 in this embodiment not only increases the travel of the control end, making the movement of both ends of the V-belt body 2 more precise, but also, after the V-belt body 2 is adjusted to a suitable position, the movement of the V-belt body 2 can be directly restricted due to the threaded connection between the locking bolt 171 and the first threaded hole 172, facilitating the cutting and connection of the V-belt body 2.

[0025] The synchronization structure in this embodiment includes a connecting shaft 5, with a first pressure roller 41 and a second pressure roller 42 fixedly mounted on both sides of the connecting shaft 5. A first sliding member 9 is rotatably connected to the center of the connecting shaft 5. The first sliding member 9 has a cuboid structure. A second sliding rail 31 is mounted on the mounting housing 1, and a second sliding groove 311 is located within the second sliding rail 31. The first sliding member 9 is slidably connected to the second sliding groove 311. This design allows for synchronous control of the first pressure roller 41 and the second pressure roller 42 on both sides engaging or disengaging from the V-belt body 2. This reduces the number of control structures, making control more efficient.

[0026] In this embodiment, the second sliding member 322 and the third sliding member 332 are rotatably mounted at both ends of the connecting shaft 5, and the third sliding rail 32 and the fourth sliding rail 33 are mounted inside the mounting housing 1. The third sliding groove 321 is located within the third sliding rail 32 and is slidably connected to the second sliding member 322. The fourth sliding groove 331 is located within the fourth sliding rail 33 and is slidably connected to the third sliding member 332. The second sliding member 322 and the third sliding member 332 on the connecting shaft 5 at both ends ensure more stable vertical movement of the connecting shaft 5 and prevent skewing.

[0027] The self-locking structure in this embodiment includes an adjusting bolt 111. A second threaded hole 112 is located on the top of the mounting housing 1 and is threadedly connected to the adjusting bolt 111. A limiting groove 91 is located on the first sliding member 9, and a second sliding hole 911 is located on the side of the limiting groove 91 near the second threaded hole 112. The adjusting bolt 111 is slidably connected to the second sliding hole 911, and a second limiting bolt 113 is located in the limiting groove 91 and is fixedly connected to the adjusting bolt 111. This self-locking structure not only ensures that the first pressure roller 41 and the second pressure roller 42 remain in the same position after disengaging from the V-belt body 2, facilitating the removal of the V-belt body 2, but also ensures that the first pressure roller 41 and the second pressure roller 42 are not prone to disengagement after engaging with the V-belt body 2.

[0028] The mounting housing 1 in this embodiment includes a top plate 11, the vertical projection surface of which is rectangular. A first connecting plate 12 and a second connecting plate 13 are fixedly disposed at the lower end of the top plate 11. The second connecting plate 13 is parallel to the first connecting plate 12, and the first connecting plate 12 and the second connecting plate 13 are parallel to the direction of movement of the V-belt body 2. A third connecting plate 14 and a fourth connecting plate 15 are fixedly disposed between the first connecting plate 12 and the second connecting plate 13. A working window 16 is disposed on the first connecting plate 12 and the second connecting plate 13, and is used to cut and connect the two ends of the V-belt body 2 through the working window 16. A first mounting plate 17 is disposed at the lower end of the third connecting plate 14, and is fixedly connected to the first connecting plate 12. A first threaded hole 172 is provided on the first mounting plate 17. A second mounting plate 18 is disposed at the lower end of the fourth connecting plate 15, and is fixedly connected to the second connecting plate 13. The second mounting plate 18 has the same structure as the first mounting plate 17. This embodiment uses a mounting housing 1 with a hollowed-out lower end, which makes it convenient for the V-belt body 2 to be detached from the mounting housing 1 from the lower end after the two ends of the V-belt body 2 are connected and fixed by connectors.

[0029] The installation process in this embodiment is as follows: First, the V-belt body 2 is installed onto the various components of the transmission system to be installed. At this time, the V-belt body 2 and the transmission system are in an unstretched state. Then, the locking bolts 171 on the first and second self-locking structures are rotated, causing the sliding rack 7 to move on the first sliding groove 81. The sliding rack 7 drives the first adjusting gear 61 to rotate, and the first adjusting gear 61 drives the two ends of the V-belt body 2 to move closer to each other until the V-belt body 2 tightens the transmission system. Then, the excess parts of the V-belt body 2 at both ends are trimmed through the working window 16, and the two ends of the V-belt body 2 are connected together through the connector. Then, the adjusting bolt 111 is rotated, causing the first sliding member 9 to move, so that the first pressure roller 41 and the second pressure roller 42 disengage from the V-belt body 2. Finally, the mounting housing 1 is moved so that it disengages from the V-belt body 2 to complete the installation.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
