Description

Technical Field

[0001] This utility model relates to the field of agricultural operation equipment technology, and in particular to a field operation walking mechanism. Background Technology

[0002] In agricultural walking mechanisms, the common walking mechanism consists of one or two driving rear wheels and a steering front wheel. The rear wheels are driven by a motor on the half-bridge. The front wheel is the driven wheel, mounted on a rotating shaft, and the steering of the walking mechanism is achieved by rotating the handle.

[0003] The existing walking mechanism uses a single motor to drive the rear wheel via a half-bridge. If one of the rear wheels slips in mud, the walking power is lost, making the walking mechanism unable to move. At the same time, steering is achieved through front wheel guidance, which requires a certain turning radius to achieve steering. This results in a large turning radius for the walking mechanism, which is not conducive to field operations. Utility Model Content

[0033] Figure 1 This is a schematic diagram illustrating the structure of a walking mechanism according to one embodiment of the present invention. Figure 2 This diagram illustrates the front view of a walking mechanism according to one embodiment of the present invention. Figure 3 This schematic diagram shows a side view of a walking mechanism according to one embodiment of the present invention, as shown below. Figure 1-3 As shown, a field operation walking mechanism of this utility model includes:

[0034] The frame 10 has a first drive wheel 101 and a second drive wheel 102 located at the rear of the direction of travel at its bottom.

[0035] The control system 20 is mounted on the frame 10. The control system 20 includes a control pedal 201, a control box 202, a first drive device 203, and a second drive device 204. The control pedal 201 is controlled to the control box 202. The control box 202 is controlled to the first drive device 203 and the second drive device 204. The first drive device 203 is controlled to the first drive wheel 101, and the second drive device 204 is controlled to the second drive wheel 102. The control pedal 201 is used to control the rotation of the first drive wheel 101 and the second drive wheel 102 respectively.

[0036] Specifically, the control pedal 201 includes an accelerator pedal (not shown in the figure) and a steering pedal (not shown in the figure), which are mounted on the pedal mounting bracket 2011. By having the operator step on the accelerator pedal and the steering pedal, the traveling mechanism can move forward, backward, turn, and rotate 360° at any angle in place.

[0037] The control box 202 integrates a driver and a control module, which can receive signals from the control pedal 201 and control the movement of the first drive wheel 101 and the second drive wheel 102 according to the signals, thereby realizing the walking control of the walking mechanism.

[0038] By setting the first drive device 203 and the second drive device 204, the first drive wheel 101 and the second drive wheel 102 can be controlled separately. Thus, when the first drive wheel 101 is controlled to move while the second drive wheel 102 does not move, the walking mechanism can be controlled to turn in place. When the first drive wheel 101 and the second drive wheel 102 are controlled to rotate at different speeds by different differential speeds, the walking mechanism with a smaller radius can be turned.

[0039] Furthermore, the first drive device 203 includes a first motor 2031, a first sprocket 2032 and a first chain 2033. The first sprocket 2032 is fixedly connected to the first drive wheel 101, and the first motor 2031 is driven by the first sprocket 2032 through the first chain 2033.

[0040] The second drive device 204 includes a second motor 2041, a second sprocket 2042, and a second chain 2043. The second sprocket 2042 is fixedly connected to the second drive wheel 102, and the second motor 2041 is connected to the second sprocket 2042 via the second chain 2043.

[0041] This configuration, through chain drive, reduces the structural complexity and high maintenance costs associated with half-bridge drives in transmission technology, while also solving the slippage problem inherent in half-bridge drives.

[0042] Furthermore, a first universal wheel 103 and a second universal wheel 104 are also provided at the bottom of the frame 10, located on the front side in the direction of travel;

[0043] The frame 10 includes a first frame 105 and a second frame 106. The second frame 106 is supported on the first frame 105. The first frame 105 is connected to the first omnidirectional wheel 103 and the first drive wheel 101, the first drive wheel 101 and the second drive wheel 102, and the second drive wheel 102 and the second omnidirectional wheel 104.

[0044] The control pedal 201, the first drive device 203, and the second drive device 204 are mounted on the first frame 105, and the control box 202 is mounted on the second frame 106.

[0045] Specifically, the first frame 105 and the second frame 106 are vehicle frames surrounded by multiple crossbeams, which can reduce the total mass of the traveling mechanism and achieve a lightweight and low-cost traveling mechanism.

[0046] The first frame 105 includes a main frame 1051, a first rear wheel swing arm 1052, and a second rear wheel swing arm 1053;

[0047] One end of the first rear wheel swing arm 1052 is used to mount the first drive wheel 101, and the other end is rotatably connected to the main frame 1051. The first rear wheel swing arm 1052 can rotate towards or away from the second frame 106. One end of the second rear wheel swing arm 1053 is used to mount the second drive wheel 102, and the other end is rotatably connected to the main frame 1051. The second rear wheel swing arm 1053 can rotate towards or away from the second frame 106.

[0048] The main frame 1051 is connected to the first universal wheel 103 and the second universal wheel 104.

[0049] With this configuration, when one side of the first rear wheel swing arm 1052 travels to a position on the bottom surface that has a protrusion or depression, its first drive wheel 101 moves up or down while the first frame 105 does not tilt synchronously. This can maintain the overall stability of the vehicle body, reduce the problem of rollover caused by inconsistent tilting of the walking mechanism, and improve the adaptability of the walking mechanism to different field bottom surfaces.

[0050] Furthermore, the frame 10 also includes a steering connecting rod 107, with the first universal wheel 103 and the second universal wheel 104 connected at both ends of the steering connecting rod 107. This arrangement enables the first universal wheel 103 and the second universal wheel 104 to turn synchronously, thereby ensuring the uniformity of the overall running direction of the traveling mechanism.

[0051] Furthermore, a shock-absorbing device 30 is provided between the first frame 105 and the second frame 106. The shock-absorbing device 30 is located on the first rear wheel swing arm 1052 and the second rear wheel swing arm 1053 respectively. The shock-absorbing device 30 is used to dampen the second frame 106 and reduce the bumping and impact force on the equipment or parts on the second frame 106.

[0052] Furthermore, a seat 40 is provided on the frame 10, the seat 40 is fixed on the second frame 106, and the control pedal 201 is located on the front side of the seat 40.

[0053] Specifically, the seat 40 is used for the operator to sit down, reducing the problem of the large amount of labor required for the operator to follow the vehicle. When the operator is seated, he / she can use the foot pedal 201 to control the direction of the walking mechanism, which can free up the hands and realize the synchronous operation of field work, thereby improving the overall work efficiency.

[0054] Furthermore, a rain shelter 50 is also provided on the frame 10. The rain shelter 50 is supported on the second frame 106 by a canopy pole. This arrangement can improve the comfort of the operator and provide shelter for the operator in rainy or sunny weather.

[0055] Furthermore, a storage box 60 is provided on the second frame 106. The storage box 60 is located on the left side of the seat 40, which makes it convenient for operators to take out and store field work materials. At the same time, a material rack 70 can also be provided at the pedal mounting frame 2011, which is also used for operators to store field work materials, making it convenient to carry out field work.

[0056] Furthermore, the control system 20 also includes a power supply 205, which is mounted on the second frame 106 and is specifically located behind the seat 40. The power supply 205 is used to provide power to the control box 202, the first drive unit 203, and the second drive unit 204.

[0057] In summary, the lightweight, low-cost, and highly adaptable agricultural operation walking mechanism of this device has a significant effect on improving work efficiency, reducing labor intensity, and enhancing agricultural production in agricultural industry management.
