Description

Technical Field

[0001] This utility model relates to the field of clutch control for micro-tillers, specifically to a labor-saving foot-operated clutch control assembly. Background Technology

[0002] Currently, the mainstream mini-tillers on the market are mainly walk-behind models. These models require a person to follow behind and push the tiller, resulting in high labor intensity and low operating efficiency. To reduce labor intensity and improve operating efficiency, some four-wheeled ride-on mini-tillers have gradually appeared on the market. The operator can sit in the driver's seat to drive or till the soil. Under the driver's seat is a clutch control mechanism for controlling clutch engagement and disengagement. This mechanism includes a clutch control foot pedal connected to a clutch shift fork shaft, which drives the shaft. The end of the clutch control foot pedal away from the foot pedal is connected to the end of the shift fork shaft. A return spring is installed on the clutch control foot pedal. When the pedal is pressed, it drives the shift fork shaft to rotate, engaging the clutch. When the pedal is released, it returns to its initial position under the action of the return spring.

[0003] The clutch control mechanism of the aforementioned riding-type mini tiller uses the rotation of the foot pedal to drive the clutch shift fork shaft to rotate, thereby achieving clutch engagement. The foot pedal requires a large force to rotate to the full position, which can easily cause operator fatigue after prolonged use. At the same time, when the road surface is bumpy, the resulting vibration can cause the foot to not be able to press the pedal fully, resulting in a semi-engaged state, which affects tillage. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a labor-saving foot-operated clutch control assembly, which solves the problem that the existing foot-operated clutch control mechanism of the riding micro-tiller is relatively laborious to step on, and is prone to fatigue after a long time of stepping on, resulting in the foot not being able to step fully and the clutch being partially engaged.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A labor-saving foot-operated clutch control assembly includes a foot pedal and a foot pedal mounting base. The foot pedal is inclined, and its front end is connected to the foot pedal mounting base via a linkage. The rear end of the foot pedal is rotatably mounted on the foot pedal mounting base. A strip-shaped hole is provided at the front end of the foot pedal mounting base, and a connecting shaft is provided within the strip-shaped hole. The rear end of the linkage is inclined upward and rotatably connected to the lower side of the foot pedal, while its front end is rotatably connected to the connecting shaft. A clutch cable is connected to the connecting shaft. When the foot pedal mounting base rotates downward under external force, it can drive the connecting shaft to roll forward along the strip-shaped hole, driving the shift fork arm at the end of the clutch cable. After the external force is released, the foot pedal can rotate upward under the reaction force of the clutch tension, returning to its initial position. In this configuration, the foot pedal is tilted, with the front end pointing upwards and the rear end rotatably connected to the foot pedal mounting base. The lower front end is rotatably connected to the foot pedal mounting base via a connecting shaft, which is positioned within a slotted hole. When the operator presses down on the foot pedal, it rotates downwards. During this downward rotation, the connecting component also rotates downwards, causing the connecting shaft to slide forward. This pulls the clutch cable connected to the connecting shaft forward, ultimately engaging the shift fork arm and achieving clutch engagement. In this process, a linkage transmission mechanism is formed between the foot pedal and the connecting component. Only a small force is needed to ensure the connecting shaft slides, and after sliding to the limit position at the end of the slotted hole, it maintains its current state. Maintaining this position requires only a small force, achieving the purpose of saving effort and reducing fatigue even after prolonged use. It also prevents a partially engaged clutch state due to an unstable foot pedal. Meanwhile, because the force required for the connecting shaft is relatively small, the reaction force required for return is also small. No separate spring is needed; the return is achieved solely by the reaction force of the clutch tension. Therefore, when the clutch needs to be disengaged, the operator removes their foot from the foot pedal. With no external force releasing the pedal, the reaction force of the clutch tension is transmitted to the connecting shaft via the clutch cable, pulling the connecting shaft backward and causing the foot pedal to quickly return to its original position.

[0007] Furthermore, the foot pedal mounting base includes a base plate and two vertical plates fixed to the base plate. The two vertical plates are parallel to each other and arranged along the length of the base plate. Two strip holes are provided, one at the front end of each of the two vertical plates. The linkage includes a linkage plate. The left and right sides of the linkage plate near the foot pedal extend towards the foot pedal to form an upper linkage plate, and the left and right sides of the linkage plate near the foot pedal mounting base extend towards the vertical plates to form a lower linkage plate. The linkage and the foot pedal mounting base are rotatably connected by a linkage shaft passing through the lower linkage plate and extending out of the corresponding side strip hole. In this way, the foot pedal mounting base consists of a base plate and two vertical plates, which is structurally stable. The vertical plates facilitate the setting of the strip holes and provide two force points for the linkage shaft, making the sliding of the linkage shaft within the strip holes smoother. Correspondingly, the linkage is plate-shaped, structurally stable, and the lower linkage plate formed by the left and right sides of the linkage plate can be arranged adjacent to the two vertical plates and rotatably connected by the linkage shaft as a pivot. There are two rotation points between the linkage and the foot pedal mounting base, making the rotation process smoother.

[0008] Furthermore, two spaced-apart linkage lugs are provided on the lower end face of the front end of the foot pedal, and two spaced-apart rotating lugs are provided on the lower end face of the rear end of the foot pedal. The two linkage lugs are positioned between the two upper connecting plates and are rotatably connected to the linkage via a first rotating shaft; the two rotating lugs are positioned between the two vertical plates and are rotatably connected to the foot pedal mounting base via a second rotating shaft. In this way, the linkage lugs of the foot pedal are correspondingly positioned with the upper connecting plates of the linkage, and after being rotatably connected via the first rotating shaft, the upper end of the linkage also has two rotation points, ensuring smooth rotation. The linkage between the foot pedal and the foot pedal mounting base thus has four connection points, resulting in very smooth operation. The linkage lugs and rotating lugs provided on the foot pedal facilitate the connection between the foot pedal, the linkage, and the foot pedal mounting base.

[0009] Furthermore, a cable adjustment seat is provided on the base plate of the foot pedal mounting seat. The middle part of the clutch cable passes through the cable adjustment seat and connects to the shift fork arm. In this way, with the cable adjustment seat provided, the length of the cable can be adjusted as needed during actual operation to meet the clutch requirements.

[0010] Furthermore, four rectangular mounting holes are provided on the base plate. This allows the foot pedal mounting bracket to be easily fixed to the tiller frame or guard plate via these four holes. Attached Figure Description

[0018] like Figures 1-4As shown, the labor-saving foot-operated clutch control assembly provided in this embodiment includes a foot pedal 1 and a foot pedal mounting base 2. The foot pedal 1 is inclined, and its front end is connected to the foot pedal mounting base 2 via a linkage 3. Its rear end is rotatably mounted on the foot pedal mounting base 2. The foot pedal mounting base 2 includes a base plate 21 and two vertical plates 22 fixed on the base plate 21. The two vertical plates 22 are parallel to each other and are arranged along the length of the base plate 21. A strip hole 23 is provided at the front end of each of the two vertical plates 22, and the two strip holes 23 are arranged along the length of the base plate 21. The foot pedal 3 is positioned with its ends corresponding to each other; a connecting shaft 4 is provided in the strip hole 23, the rear end of the connecting member 3 is inclined upward and rotatably connected to the lower side of the foot pedal 1, and the front end is sleeved on the connecting shaft 4 and rotatably connected to the connecting shaft 4; a clutch cable 5 is connected to the connecting shaft 4. When the foot pedal mounting seat 2 rotates downward under the action of external force, it can drive the connecting shaft 4 to roll forward along the strip hole 23, driving the shift fork arm at the end of the clutch cable 5; after the external force is released, the front end of the foot pedal 1 can rotate upward under the reaction action of the clutch tension and return to the initial position. In this configuration, the foot pedal 1 is tilted, with its front end pointing upwards and its rear end rotatably connected to the foot pedal mounting base 2. The lower front end is rotatably connected to the foot pedal mounting base 2 via a connecting member 3 and a connecting shaft 4, which is positioned within a slotted hole 23. When the operator presses down on the foot pedal 1, it rotates downwards. During this downward rotation, the connecting member 3 also rotates downwards, causing the connecting shaft 4 to slide forward. This pulls the clutch cable 5 connected to the connecting shaft 4 forward, ultimately engaging the shift fork arm and achieving clutch engagement. In this process, a linkage transmission mechanism is formed between the foot pedal 1 and the connecting member 3. Only a small force is needed to ensure the connecting shaft 4 slides. After sliding to the limit position at the end of the slotted hole 23, it maintains its current state. Maintaining this state requires only a small force, achieving the purpose of saving effort. Even after prolonged use, fatigue is less likely, and a semi-engaged state due to an unstable foot pedal is avoided. Meanwhile, since the force required for the connecting shaft 4 is relatively small, the reaction force required for return is also small. No separate spring is needed; the return is achieved solely by the reaction force of the clutch tension. Therefore, when the clutch needs to be disengaged, the operator removes their foot from the foot pedal 1. With no external force released, the reaction force of the clutch tension is transmitted to the connecting shaft 4 via the clutch cable 5, pulling the connecting shaft 4 backward and causing the foot pedal 1 to quickly return to its original position. The foot pedal mounting base 2 consists of a base plate 21 and two upright plates 22, providing a stable structure. The upright plates 22 facilitate the installation of the slotted holes 23 and provide two leverage points for the connecting shaft 4, resulting in smoother sliding of the connecting shaft 4 within the slotted holes 23.

[0019] like Figure 5As shown, the linkage 3 includes a linkage plate 31. The linkage plate 31 extends from the left and right sides of its end near the foot pedal 1 towards the foot pedal 1, forming an upper linkage plate 32. The linkage plate 31 extends from the left and right sides of its end near the foot pedal mounting base 2 towards the vertical plate 22, forming a lower linkage plate 33. The linkage 3 and the foot pedal mounting base 2 are rotatably connected by a linkage shaft 4 passing through the lower linkage plate 33 and extending out through the corresponding side of the slotted hole 23. Thus, the linkage 3 is plate-shaped, structurally stable, and the lower linkage plate 33 formed by the left and right sides of the linkage plate 31 can be arranged adjacent to the two vertical plates 22, and can be rotatably connected by the linkage shaft 4 as a pivot. The linkage 3 and the foot pedal mounting base 2 have two rotation points, making the rotation process smoother.

[0020] Furthermore, two spaced-apart connecting lugs 11 are provided on the lower end face of the front end of the foot pedal 1, and two spaced-apart rotating lugs 12 are provided on the lower end face of the rear end of the foot pedal 1. The two connecting lugs 11 are positioned between the two upper connecting plates 32 and are rotatably connected to the connecting member 3 via the first rotating shaft 7; the two rotating lugs 12 are positioned between the two vertical plates 22 and are rotatably connected to the foot pedal mounting base 2 via the second rotating shaft 8. In this way, the connecting lugs 11 of the foot pedal 1 are correspondingly positioned with the upper connecting plates 32 of the connecting member 3. After being rotatably connected via the first rotating shaft 7, the upper end of the connecting member 3 also has two rotation points, allowing for smooth rotation. The connecting member 3 between the foot pedal 1 and the foot pedal mounting base 2 thus has four connection points, resulting in very smooth operation. The connecting lugs 11 and rotating lugs 12 provided on the foot pedal 1 facilitate the connection between the foot pedal 1, the connecting member 3, and the foot pedal mounting base 2.

[0021] Furthermore, a cable adjustment seat 6 is provided on the base plate 21 of the foot pedal mounting seat 2. The clutch cable 5 passes through the cable adjustment seat 6 in the middle and connects to the shift fork arm. In this way, with the cable adjustment seat 6 provided, the length of the cable can be adjusted as needed during actual operation to meet the clutch requirements.

[0022] Furthermore, four rectangular mounting holes 24 are provided on the base plate 21. In this way, the foot pedal mounting base 2 can be fixedly installed on the micro-tiller frame or guard plate through the four mounting holes 24, making installation convenient.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
