Description

Technical Field

[0001] This utility model relates to the field of plant protection machinery clutch technology, and in particular to a remote control assisted clutch device. Background Technology

[0002] With the development of agricultural machinery, more and more agricultural machines are becoming increasingly larger, especially self-propelled plant protection machinery. Because these machines contain a relatively large pesticide tank, for optimal configuration, the cab is often placed at the front, with the engine in the middle or rear. This increases the distance between the control and actuators, particularly the clutch mechanism, increasing operating resistance. As the pesticide tank capacity and engine power increase, the resistance required for clutch operation also increases, further increasing the resistance during long-distance operation. Frequent and forceful clutch pedal operation can easily cause operator fatigue and reduce work efficiency.

[0003] In current technology, some large agricultural machinery uses extended clutch cables or pneumatic / hydraulic power steering when the operating position is far from the engine clutch. These methods often result in complex structures, inconvenient operation, and high costs. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing plant protection machinery, which typically uses extended clutch cables or pneumatic / hydraulic power-assisted clutches. These methods often suffer from complex structures, inconvenient operation, and high costs. Therefore, this invention proposes a remote-controlled power-assisted clutch device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a remote-controlled power-assisted clutch device, comprising a pedal, one end of which is connected to a clutch cable via a pin, a support tube at one end of the pedal, a control fixing shaft at one end of the support tube, a control pressure plate and a clutch pull plate fixedly mounted on the outer wall of the control fixing shaft, one end of the clutch cable being connected to the control pressure plate via a pin, a cylinder fixing plate fixedly mounted on the top of the support tube, a power-assisted cylinder being fixedly connected to one end of the cylinder fixing plate via bolts, a clutch pull rod being connected to one end of the clutch pull plate via a pin, and an upper hole and a lower hole penetrating through the outer wall of the pedal and the outer wall of the control pressure plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by pressing the pedal, the pedal connects to the clutch cable, which pulls the control plate. The control plate contacts the power-assisted cylinder, causing the power-assisted cylinder to retract, thereby pulling the clutch lever. The upper hole of the pedal connects to the upper hole of the control plate, enabling a pulling operation. When connected through the lower hole of the pedal to the lower hole of the control plate, a pushing operation is possible. Both operations can engage and disengage the engine clutch. This design combines a clutch-assisted cylinder and a clutch cable for remote clutch operation.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-5As shown, this utility model provides a remote-controlled power clutch device, including a pedal 1. One end of the pedal 1 is connected to a clutch cable 4 via a pin. One end of the pedal 1 is provided with a support tube 6. One end of the support tube 6 is provided with a control fixing shaft 13. A control pressure plate 9 and a clutch pull plate 11 are fixedly installed on the outer wall of the control fixing shaft 13. One end of the clutch cable 4 is connected to the control pressure plate 9 via a pin. A cylinder fixing plate 7 is fixedly installed on the top of the support tube 6. One end of the cylinder fixing plate 7 is fixedly connected to a power cylinder 8 via bolts. One end of the clutch pull plate 11 is connected to a clutch lever 10 via a pin. An upper hole 12 and a lower hole 3 are provided through the outer wall of the pedal 1 and the outer wall of the control pressure plate 9.

[0027] The overall effect of Embodiment 1 is as follows: by pressing the pedal 1, the pedal 1 connects to the clutch cable 4, which pulls the control plate 9. The control plate 9 contacts the contact point of the power assist cylinder 8, causing the power assist cylinder 8 to retract, thereby pulling the clutch lever 10. Furthermore, the upper hole 12 of the pedal 1 connects to the upper hole 12 of the control plate 9, enabling a pulling operation. When connected through the lower hole 3 of the pedal 1 to the lower hole 3 of the control plate 9, a pushing operation is possible. Both operations can achieve engine clutch engagement and disengagement. This combination of the clutch assist cylinder 8 and the clutch cable 4 enables remote clutch operation. To adapt to different environments, a power assist clutch device integrating both push-rod and pull-rod assist methods is designed. This allows for simple and effortless remote operation of the engine clutch.

[0028] Example 2, as Figures 1-5 As shown, the top of the pedal 1 is provided with a slot 24, the inner side wall of the slot 24 is provided with a limiting groove 25, the inner wall of the limiting groove 25 is fixedly installed with a spring 26, the end of the spring 26 near the slot 24 is fixedly installed with a locking block 27, the end of the locking block 27 near the spring 26 is fixedly installed with a connecting rod 28, one end of the connecting rod 28 passes through the pedal 1 and is fixedly installed with a movable plate 29.

[0029] Furthermore, a plate 21 is slidably installed inside the slot 24. A slot 22 is provided at one end of the plate 21 near the limiting slot 25. An anti-slip plate 2 is fixedly installed on the top of the plate 21.

[0030] Furthermore, multiple evenly distributed anti-slip strips 23 are fixedly installed on the top of the anti-slip plate 2 to increase the friction between the sole of the shoe and the pedal 1, prevent the user from slipping, and improve the safety of operation.

[0031] Furthermore, a pull wire fixing plate 5 is provided on the outer wall of the support tube 6. A fixing hole 14 is provided through the outer wall of the pull wire fixing plate 5. The pull wire fixing plate 5 is used to fix the clutch pull wire 4. When fixing, the staff needs to pass the clutch pull wire 4 through the fixing hole 14 first.

[0032] Furthermore, a storage groove 17 is provided on the inner wall of the fixing hole 14, and a threaded hole 18 is provided through the inner wall of the storage groove 17. A threaded rod 19 is threadedly connected inside the threaded hole 18. A handle 16 is fixedly installed at one end of the threaded rod 19, and a clamping plate 20 is movably connected to the end of the threaded rod 19 near the fixing hole 14. When the operator rotates the handle 16, the handle 16 drives the threaded rod 19 to rotate in the threaded hole 18, so that the threaded rod 19 moves along the threaded hole 18, thereby pushing the clamping plate 20 to move along the storage groove 17. When both rubber pads 15 are in contact with the outer wall of the clutch cable 4, the pressure applied to the clutch cable 4 by the clamping plate 20 increases the friction between the clutch cable 4 and the rubber pads 15, thus fixing the clutch cable 4.

[0033] Furthermore, rubber pads 15 are fixedly installed on both the outer wall of the clamping plate 20 and the inner wall of the fixing hole 14. During use, the clutch cable 4 will experience relative movement or friction with the cable fixing plate 5, especially under frequent clutch operation. The rubber pads 15 can reduce the direct friction between the two and avoid hard friction between metals, thereby extending the service life of the clutch cable 4 and the cable fixing plate 5.

[0034] Furthermore, the outer wall of the rubber pad 15 is in contact with the outer wall of the clutch cable 4, increasing the contact area between the rubber pad 15 and the clutch cable 4, making the fixation more secure and reducing the probability of the clutch cable 4 shaking after it is fixed.

[0035] Furthermore, the outer wall of the clamping plate 20 fits against the inner wall of the storage groove 17, which facilitates the limiting of the clamping plate 20 and prevents the clamping plate 20 from rotating when the threaded rod 19 rotates, thereby affecting the fixation of the clutch cable 4.

[0036] Furthermore, the outer wall of the insert plate 21 fits against the inner wall of the slot 24, and the outer wall of the locking block 27 fits against the inner wall of the slot 22. When the insert plate 21 is fully inserted into the slot 24 and the locking block 27 is inserted into the slot 22, the insert plate 21 can be fixed in place to prevent the insert plate 21 from shaking.

[0037] The effect achieved by the entire embodiment 2 is that when the anti-slip plate 2 is damaged after long-term use, the staff pulls the movable plate 29. The movable plate 29 drives the locking block 27 away from the slot 22 through the connecting rod 28. At this time, the staff can take out the insert plate 21 to replace the anti-slip plate 2. Then the staff inserts the insert plate 21 into the slot 24. The insert plate 21 contacts the inclined surface of the locking block 27, pushing the locking block 27 into the limiting groove 25. The spring 26 is compressed. When the slot 22 moves next to the locking block 27, the spring 26 pushes the locking block 27 into the slot 22. The installation is completed in this way, which improves the replacement efficiency.

[0038] Working principle: By pressing pedal 1, pedal 1 connects to clutch cable 4, which pulls control plate 9. Control plate 9 contacts the power steering cylinder 8, causing cylinder 8 to retract and thus pulling clutch lever 10. The upper hole 12 of pedal 1 connects to the upper hole 12 of control plate 9, enabling a pulling operation. When connected via the lower hole 3 of pedal 1 to the lower hole 3 of control plate 9, a pushing operation is possible. Both operations engage and disengage the engine clutch. When fixing the clutch cable 4, the worker passes the clutch cable 4 through the fixing hole 14, and then the worker rotates the handle 16. The handle 16 drives the threaded rod 19 to rotate in the threaded hole 18, so that the threaded rod 19 moves along the threaded hole 18, thereby pushing the clamping plate 20 to move along the storage groove 17. When both rubber pads 15 are in contact with the outer wall of the clutch cable 4, the pressure applied by the clamping plate 20 to the clutch cable 4 increases the friction between the clutch cable 4 and the rubber pads 15, thus fixing the clutch cable 4. When the anti-slip plate 2 becomes damaged after prolonged use, the worker pulls the movable plate 29. The movable plate 29, through the connecting rod 28, causes the locking block 27 to leave the slot 22. At this time, the worker can remove the insert plate 21 to replace the anti-slip plate 2. Then, the worker inserts the insert plate 21 into the slot 24. The insert plate 21 contacts the inclined surface of the locking block 27, pushing the locking block 27 into the limiting groove 25. The spring 26 is compressed. When the slot 22 moves next to the locking block 27, the spring 26 pushes the locking block 27 into the slot 22. This completes the installation and improves the replacement efficiency.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
