Description

Technical Field

[0001] This utility model belongs to the technical field of clutch pedals for rotary tillers, and provides a semi-self-locking clutch pedal mechanism that reduces operating intensity, improves operating stability, enhances safety, and extends clutch service life. Background Technology

[0002] In the modernization and iteration of agriculture, various agricultural implements, including those for tilling, sowing, and harvesting, are constantly being updated to reduce the labor intensity of agricultural workers. In tilling, a small, rideable rotary tiller has gained widespread demand to adapt to various undulating hills and small fields. Initially designed solely for functionality, this type of machine has evolved to meet the increasing demands for comfort, reliability, and safety.

[0003] To ensure safety during use, riding-type rotary tillers generally use normally open clutches. As the name suggests, a normally open clutch is not disengaged when the clutch pedal is not depressed; external force is required to engage the clutch, ensuring the machine stops when the pedal is released. Riding-type rotary tillers on the market generally use the clutch design of traditional walk-behind rotary tillers, connecting the clutch arm with cables or springs. Depressing the clutch pedal transfers the foot's force to the clutch arm. However, this direct-depress method causes the clutch to loosen or tighten as the pedal moves. In fact, during operation, the pedal position is easily affected by machine vibrations or fatigue from repeated pedaling, leading to continuous engagement and disengagement of the clutch. This constant tightening and loosening of the internal friction plates accelerates wear and ultimately clutch failure. In summary, the existing clutch control structure of riding-type rotary tillers suffers from frequent clutch tightening and loosening, affecting operational stability, resulting in short clutch lifespan, high operational intensity, and low safety. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a semi-self-locking clutch pedal mechanism that reduces operational intensity, improves operational stability, enhances safety, and extends the service life of the clutch.

[0020] To facilitate the installation and removal of the clutch spring 3, in the above embodiment, the clutch rocker plate 4 is further provided with a spring hole 4-4, the clutch rocker arm 2 is provided with a clutch spring hole 2-1, and the two ends of the clutch spring 3 are respectively hooked into the spring hole 4-4 and the clutch spring hole 2-1.

[0021] To facilitate the installation and removal of the clutch reset spring 1, in the above embodiment, the clutch swing arm 2 is further provided with a clutch reset spring mounting hole 2-2, and the gearbox body 15 with integrated clutch is provided with another clutch reset spring mounting hole. The two ends of the clutch reset spring 1 are respectively hooked into the clutch reset spring mounting hole 2-2 and the other clutch reset spring mounting hole.

[0022] To facilitate the installation and removal of the pedal reset spring 10, in the above embodiment, the clutch pedal 7 is further provided with a reset spring hole 7-2, and the pedal cover 16 of the gearbox body 15 with integrated clutch is provided with a bottom hole. The two ends of the pedal reset spring 10 are respectively hooked into the reset spring hole 7-2 and the bottom hole.

[0023] All components in the above embodiments are commercially available products. Note that the instruction manual is attached... Figure 5 When the clutch pedal 7 shown is a solid line, it indicates that the clutch pedal 7 is in the released state; when the clutch pedal 7 is a dashed line, it indicates that the clutch pedal 7 is in the pressed state.

[0024] The working process of the structure described in the above embodiment is as follows: When the clutch pedal 7 is pressed down, the pin groove 7-5 of the clutch pedal 7 will simultaneously press down on the locking pin 4-3 of the clutch rocker plate 4. The locking pin 4-3 moves downward and presses down on the locking inclined surface 6-6 of the clutch block 6, causing the clutch block 6 to rotate around the clutch block shaft 11-2. Meanwhile, the clutch rocker arm 2, which presses down on the clutch, is connected to the clutch rocker plate 4 through the clutch tension spring 3. When it presses down on the clutch block 6 and moves downward, it also drives the clutch rocker arm 2 to rotate around the clutch rotation shaft 2-3, thereby causing the clutch fork 2-4 to press down on the clutch. When the clutch pedal 7 is continuously depressed, after the clutch block 6 is pressed to a certain angle, the locking pin 4-3 will disengage from the inclined surface 6-6 of the clutch block and reach the pin notch 6-4 of the clutch block 6. At this time, under the torque of the clutch block torsion spring 5, the clutch block 6 springs back in the opposite direction, causing the pin notch 6-4 to spring back and lock the locking pin 4-3. At this time, the locking pin 4-3 is locked, and the clutch is also pressed by the clutch fork. After this, even if the clutch pedal 7 is released slightly, the clutch will not disengage because the clutch block shaft 11-2 is locked. When the clutch pedal 7 is continuously released, the clutch pedal rises and rotates in the opposite direction under the tension of the pedal return spring 10. When the pedal lever 7-3 contacts the return plate 6-3 on the clutch retainer 6, the continuous tension of the pedal return spring presses the clutch retainer 6 down clockwise. At this time, due to the displacement of the clutch retainer, the retaining pin 4-3 will disengage from the pin notch 6-4. The clutch lever arm returns to its original position under the force of the internal clutch return spring and the clutch return spring 1, and the clutch is released. During this process, due to the setting of the pedal return limit block 7-4 and the clutch pedal return limit part 13-1, even if the clutch pedal 7 is continuously released, the pedal return limit block 7-4 will be locked at the clutch pedal return limit part 13-1, and the clutch pedal 7 will not continue to rise due to the tension of the pedal return spring 10.

[0025] The structure described above achieves the function of disengaging the clutch when the pedal is released. Within the interval between clutch locking and unlocking, the clutch pedal 7 has a certain rotational floating space, providing the operator with room to loosen the pedal due to machine vibration or fatigue, without affecting the clutch locking state. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
