Description

Technical Field

[0001] This utility model relates to the field of pedal mechanism technology, and in particular to a pedal mechanism for a tractor. Background Technology

[0002] Tractors are self-propelled power units used to traction and drive work machinery to complete various mobile operations. They can also be used as power for stationary operations. They consist of systems or devices such as engine, transmission, travel, steering, hydraulic suspension, power output, electrical instruments, driving control, and traction.

[0003] For example, the authorization announcement number "CN204172697U" is named a pedal mechanism on a tractor. It is solid and stable when pressing the accelerator, non-slip and safe, suitable for people with different foot sizes, easy to disassemble, and the clutch and accelerator are installed on the same axis.

[0004] The above-mentioned and existing technologies have the following drawbacks: because the driver's shoes are prone to getting mud on them, the anti-slip strips of the tractor are prone to getting mud in, making them difficult to clean; and the additional pedals need to be fixed to the accelerator pedal with bolts, making it inconvenient to replace them with additional pedals of different widths. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pedal mechanism for tractors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a pedal mechanism for a tractor, including a main shaft, which is fixedly connected to the tractor body by a fixing member. A clutch rocker arm and a throttle rocker arm are rotatably connected to the left and right sides of the main shaft, respectively. A clutch pedal and a throttle pedal are connected to the upper ends of the clutch rocker arm and the throttle rocker arm, respectively. A first stop is provided at the left end of the front surface of the clutch pedal. The front surface of the clutch pedal has multiple inclined first anti-slip grooves. A linkage mechanism is provided at the lower end of the clutch rocker arm. The front surface of the throttle pedal has multiple inclined second anti-slip grooves. An auxiliary pedal is slidably connected to the throttle pedal. The auxiliary pedal is fixed to the throttle pedal by a locking device. A second stop is provided at the right end of the front surface of the auxiliary pedal. A pedal cover is provided on the front surface of the auxiliary pedal. The front surface of the pedal cover has multiple inclined third anti-slip grooves. Both ends of the rear surface of the pedal cover have lower edges, which are engaged with the auxiliary pedal by snap-fit ​​blocks. The throttle rocker arm and the clutch pedal are both connected to the tractor body by a first spring.

[0008] Preferably, the inner wall of the accelerator pedal is provided with a plurality of T-shaped grooves, and the front surface of the auxiliary pedal is provided with T-shaped blocks that correspond one-to-one with the T-shaped grooves, with the front end of the T-shaped blocks extending into the T-shaped grooves.

[0009] Preferably, the locking device includes two locking caps, which are respectively disposed above and below the accelerator pedal. The upper and lower surfaces of the auxiliary pedal are provided with positioning grooves. The opposing side surfaces of the two locking caps are provided with locking posts. The opposing ends of the two locking posts pass through the accelerator pedal and extend into the corresponding positioning grooves. A second spring is sleeved on the outside of the locking post. One end of the second spring is connected to the accelerator pedal, and the other end of the second spring is connected to the locking cap.

[0010] Preferably, the two snap-fit ​​caps each have a plurality of operating grooves arranged in a ring on the opposite side surface.

[0011] Preferably, the rear surface of the accelerator pedal is provided with support blocks at both the upper and lower ends.

[0012] The tractor pedal mechanism proposed in this utility model has the following advantages: The locking device allows for easy adjustment when changing drivers to accommodate different foot widths. By pulling two locking caps, the locking pins disengage from the positioning slots. Then, the auxiliary pedal is pulled and adjusted to the appropriate position. The second spring's elasticity causes the locking pins to extend into the new positioning slot, securing the auxiliary pedal. The locking block then engages with the auxiliary pedal, further securing the new pedal cover. This process eliminates the need for bolts, making it very convenient and quick to adjust to different pedal widths. Furthermore, when the driver's shoes get muddy, the first, second, and third anti-slip grooves on the tractor facilitate quick and easy removal of mud from the edges of these grooves.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figs. 1-3 A pedal mechanism for a tractor includes a main shaft 1, which is fixedly connected to the tractor body via a fixing member 2. A clutch rocker arm 3 and a throttle rocker arm 4 are rotatably connected to the left and right sides of the main shaft 1, respectively. A clutch pedal 5 and a throttle pedal 6 are correspondingly connected to the upper ends of the clutch rocker arm 3 and the throttle rocker arm 4. A first stop block 7 is provided on the left end of the front surface of the clutch pedal 5, and multiple inclined first anti-slip grooves 8 are provided on the front surface of the clutch pedal 5. A linkage mechanism 9 is provided at the lower end of the clutch rocker arm 3, and multiple inclined second anti-slip grooves are provided on the front surface of the throttle pedal 6. The accelerator pedal 6 is slidably connected to the through groove 10, and the auxiliary pedal 11 is fixed to the accelerator pedal 6 by a locking device. The right end of the front surface of the auxiliary pedal 11 is provided with a second stop block 12, and the front surface of the auxiliary pedal 11 is provided with a pedal cover 13. The front surface of the pedal cover 13 is provided with multiple inclined third anti-slip through grooves 14. Both ends of the rear surface of the pedal cover 13 are provided with lower edges 15, and the lower edges 15 are engaged with the auxiliary pedal 11 by a snap-fit ​​block 16. The accelerator rocker arm 4 and the clutch pedal 5 are both connected to the tractor body by a first spring 17.

[0019] The accelerator pedal 6 has multiple T-shaped grooves 18 on its inner front wall, and the auxiliary pedal 11 has T-shaped blocks 19 on its front surface that correspond to and match the T-shaped grooves 18. The front end of the T-shaped blocks 19 extends into the T-shaped grooves 18.

[0020] The locking device includes two locking caps 20, which are respectively located above and below the accelerator pedal 6. The upper and lower surfaces of the auxiliary pedal 11 are provided with positioning grooves 21. The opposing side surfaces of the two locking caps 20 are provided with locking posts 22. The opposing ends of the two locking posts 22 pass through the accelerator pedal 6 and extend into the corresponding positioning grooves 21. A second spring 23 is sleeved on the outside of the locking post 22. One end of the second spring 23 is connected to the accelerator pedal 6, and the other end of the second spring 23 is connected to the locking cap 20.

[0021] Each of the two snap-fit ​​caps 20 has multiple operating grooves 24 arranged in a ring on one side of its facing surface. The operating grooves 24 facilitate the user's gripping of the snap-fit ​​caps 20.

[0022] The accelerator pedal 6 has support blocks 25 at both the upper and lower ends of its rear surface. The support blocks 25 serve to support the auxiliary pedal 11.

[0023] Working principle: When this pedal mechanism is working, pressing the clutch pedal 5 drives the linkage mechanism 9 to perform the clutch action. The presence of the first spring 17 allows the clutch pedal 5 to automatically return when the foot leaves the pedal. The accelerator pedal 6 works in the same way. If it is necessary to change to a driver with a different foot width, first remove the pedal cover 13, then pull the two snap-fit ​​caps 20 to disengage the snap-fit ​​pins 22 from the positioning grooves 21, then pull the auxiliary pedal 11 to adjust it to the appropriate position. The elastic force of the second spring 23 causes the snap-fit ​​pins 22 to extend into the new positioning grooves 21, fixing the auxiliary pedal 11. The snap-fit ​​block 16 engages with the auxiliary pedal 11, thereby fixing the new pedal cover 13. The above process does not require the use of bolts for fixing, making it very convenient and quick to adjust to auxiliary pedals 11 of different widths. When the driver's shoes step on mud, the first anti-slip groove 8, the second anti-slip groove 10 and the second anti-slip groove 10 provided on this tractor can easily and quickly clear the mud from the edges of the grooves.
