Description

Technical Field

[0001] The present invention relates to the technical field of clutches, in particular to a high-stability clutch for a direct-connected trencher. Background Art

[0002] The clutch of a direct-coupled trencher is a key component in the power transmission system of a direct-coupled trencher. It is designed to ensure reliable power transmission and precise control, while adapting to the high-intensity operation requirements of the trencher under complex working conditions.

[0003] In the initial stage of clutch disengagement of a direct-coupled trencher, the static friction between the friction plate and the flywheel (the greatest resistance) must be overcome. The driver needs to exert great pedaling force to initiate the disengagement, which can easily lead to leg fatigue. Especially in farmland operations with frequent starts and stops, operating efficiency is greatly reduced. During the process of continuous and strong pedaling, excessive pedaling due to inertia or misoperation may cause the mechanical components of the release fork to be subjected to instantaneous impact loads, causing deformation or fracture, and causing rigid collision between the release bearing and the pressure plate, accelerating wear or even burning, affecting the high stability of the direct-coupled trencher clutch. To this end, this paper proposes a high-stability clutch for direct-coupled trenchers. Summary of the Invention

Through this process, impact loads are suppressed, and damage to the core components of the clutch such as the release fork 104 and the release bearing 103 caused by heavy stepping is avoided, ensuring the high-stability use of the direct-connected trencher clutch.

[0044] Preferably, the pushing component includes an installation box 201 fixed on the outer side of the clutch housing 102.

A sliding component for assisting the sliding connection of the rack 302 is arranged between the inside of the installation box 201 and the rack 302.

[0045] It should be noted here that: through the stepping transmission component, the rack 302 is forced to move. During the movement of the rack 302, through the meshing transmission between the rack 302 and the gear 301, the gear 301 and the installation shaft 202 on the gear 301 rotate. During the rotation of the installation shaft 202, the release fork 104 is driven to move. Through the movement of the release fork 104, the release bearing 103 is pushed to complete the driving of the release bearing 103.

[0046] Preferably, the stepping transmission component includes a connecting rod 501 arranged on the installation box 201. A chute 502 is opened at the front end of the connecting rod 501.

The mounting rods 804 are fixed between the two sets of mounting brackets 801. A rotating assembly for rotating the threaded rod 803 is provided inside the installation box 201;

[0052] It should be noted here that: during the rotation of the installation shaft 202, through transmission, the threaded rod 803 is driven to rotate. During the rotation of the threaded rod 803, through the meshing transmission between the threaded rod 803 and the threaded sleeve 802 and the sliding guiding action of the two sets of mounting rods 804, the stressed lifting platform 601 moves upward. During the upward movement of the lifting platform 601, the support plate 602 and the sliding seat 603 are driven to move upward synchronously. Through the upward movement of the support plate 602 and the sliding seat 603, the distance from the connection point of the sliding seat 603 and the support plate 602 to the connection point of the connecting plate 503 and the rack 302 and the end of the connecting rod 501 is adjusted, so that the length of L1 is greater than that of L2.

[0056] It should be noted here that during the rotation of the installation shaft 202, the transmission shaft 1001 and the worm 903 are driven to rotate through the connection and transmission between the chain 1002 and the two groups of sprockets.

[0057] Embodiment 2

[0058] Please refer to Figure 4 and Figure 5 In this embodiment, a further description is made of Embodiment 1. The sliding assembly in the figure includes a plurality of sliding holes 401 opened on the rack 302. A sliding rod 402 is slidably connected to the sliding holes 401. The sliding rod 402 is fixed to the installation box 201. A spring 403 is sleeved on the outer side of the sliding rod 402. The two ends of the spring 403 are respectively abutted against the inner wall of the installation box 201 and one side of the rack 302.

[0059] It should be noted here that through the sliding holes 401 and the sliding rod 402, the sliding of the rack 302 is guided after being stressed, and through the spring 403, it is convenient for the rack 302 to reset after the movement.

[0060] Preferably, the connection assembly includes an installation groove 701 opened on one side of the connecting rod 501. A plurality of guide rods 702 are slidably connected to the sliding seat 603. The guide rods 702 are fixed to the installation groove 701.

[0061] It should be noted here that through the installation groove 701 and the guide rods 702, the slidable connection of the sliding seat 603 on one side of the connecting rod 501 is assisted.

[0062] In this solution: a high-stability clutch for a direct-connected ditcher includes the following steps:

[0063] When the direct-connected ditcher clutch is in use, the operation is realized by driving the movement of the release bearing 103. When the clutch is in the engaged state, there is a certain gap between the release bearing 103 and the release fingers of the clutch pressure plate. The pressure plate presses the friction plate tightly against the flywheel under the action of elastic force. At this time, the power of the engine is transmitted to the clutch pressure plate through the flywheel, and then transmitted to the working parts of the gearbox 101 through the friction plate, enabling the ditcher to operate normally. When power needs to be cut off, the driver steps on the pedal, and through the transmission of the stepping transmission assembly, driving assembly and pushing assembly, the release bearing 103 is pushed to move. The release bearing 103 pushes the release fingers of the pressure plate, causing the pressure plate to move backward against the elastic force, so that the pressure plate is separated from the friction plate, cutting off the power transmission between the engine and the working parts, and the ditcher stops operating;

[0064] During the process of driving the pedal by stepping on it, due to the connection of the connecting rod 501 and the supporting effects of the lifting table 601, the supporting plate 602 and the sliding seat 603, the connecting rod 501 rotates inside the installation box 201. During the rotation of the connecting rod 501, through the connection of the connecting plate 503 on the chute 502, the rack 302 is pushed to move under force. During the movement of the rack 302, through the meshing transmission between the rack 302 and the gear 301, the gear 301 and the mounting shaft 202 on the gear 301 rotate. During the rotation of the mounting shaft 202, the release fork 104 is driven to move. Through the movement of the release fork 104, the release bearing 103 is pushed to complete the driving of the release bearing 103;

[0065] During the process of driving the release bearing 103 by stepping on it, in the axial direction of the connecting rod 501, the distance from the connection point of the connecting plate 503 and the rack 302 to the connection point of the sliding seat 603 and the supporting plate 602 is L1, and the distance from the connection point of the sliding seat 603 and the supporting plate 602 to the end of the connecting rod 501 is L2 (see Figure 9 and Figure 10 ). At the initial stage of stepping on, the length of L1 is less than L2 (see Figure 9 ). At this time, it is a labor-saving support lever, making it more labor-saving at the initial stage of stepping on the clutch and reducing the fatigue on the legs. Especially in the farm work with frequent starts and stops, the operation efficiency is guaranteed. As the stepping continues, during the rotation of the mounting shaft 202, through the connection and transmission of the chain 1002 and the two groups of sprockets, the drive shaft 1001 and the worm 903 are driven to rotate. During the rotation of the worm 903, through the meshing transmission between the worm 903 and the worm gear 902, the worm gear 902 and the connecting shaft 901 on the worm gear 902 are driven to rotate. Through the rotation of the connecting shaft 901, the threaded rod 803 is driven to rotate. During the rotation of the threaded rod 803, through the meshing transmission between the threaded rod 803 and the threaded sleeve 802 and the sliding guiding effects of the two groups of mounting rods 804, the stressed lifting table 601 moves upward. During the upward movement of the lifting table 601, the supporting plate 602 and the sliding seat 603 are driven to move upward synchronously. Through the upward movement of the supporting plate 602 and the sliding seat 603, the distances from the connection point of the sliding seat 603 and the supporting plate 602 to the connection point of the connecting plate 503 and the rack 302 and the end of the connecting rod 501 are adjusted, making the length of L1 greater than L2 (see Figure 10), at this time, it is a laborious lever to support, making the later stage of stepping on the clutch more laborious. A greater force needs to be applied for the same stepping displacement, which forcibly reduces the separation speed. At the same time, through the resistance feedback, the driver is reminded that "it has been completely separated" to avoid over-operation. Through this process, the impact load is suppressed, and damage to the core components of the clutch such as the release fork 104 and release bearing 103 caused by heavy stepping is avoided, ensuring the high-stability use of the direct-connected ditcher clutch.
