In order to adapt to various plots, the machine generally uses a crawler-type walking chassis for driving. After harvesting one ridge, it is necessary to perform cross-ridge operations.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] The purpose of the present invention is to provide a walking chassis, a working device and a working method to solve the problems existing in the above related technologies, reduce the difficulty of striding across ridges during the field walking operation of mechanical equipment, improve the working efficiency of mechanical equipment, ensure the normal operation of the equipment, and extend the service life of the equipment.

[0047] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0048] Embodiment 1

[0049] This embodiment provides a walking chassis, please refer to Figures 1 - 10, including a frame 1 and a traveling mechanism 2. The traveling mechanism 2 is connected to the frame 1, and the traveling mechanism 2 can drive the frame 1 to move. It further includes a lifting mechanism 3 and a rotating mechanism 4. The lifting mechanism 3 includes an upper support 301, a lower base 302, and a telescopic assembly 303. The upper support 301 can be connected to the frame 1. The lower base 302 is located below the upper support 301 and can contact the ridge. The telescopic assembly 303 connects the upper support 301 and the lower base 302, and the height of the telescopic assembly 303 can be adjusted. The upper support 301 is rotationally connected to the frame 1 by the rotating mechanism 4, and the rotating mechanism 4 can drive the frame 1 and the traveling mechanism 2 to rotate.

[0050] For the traveling chassis of the present invention, a lifting mechanism 3 is provided below the frame 1. The telescopic assembly 303 drives the lower base 302 to move so that it contacts the ridge, thereby enabling the lifting mechanism 3 to lift the frame 1 and the traveling mechanism 2. The upper support 301 of the lifting mechanism 3 is connected to the frame 1 by the rotating mechanism 4, and the rotating mechanism 4 can drive the frame 1 and the traveling mechanism 2 to rotate. When it is necessary to cross the ridge during field operations, the lifting mechanism 3 can be used to lift the frame 1 and the traveling mechanism 2. After the rotating mechanism 4 drives the frame 1 and the traveling mechanism 2 to rotate by a certain angle, the traveling direction of the traveling mechanism 2 is oriented towards the direction of crossing the ridge. Then the lifting mechanism 3 lowers the frame 1 and the traveling mechanism 2, and the telescopic assembly 303 of the lifting mechanism 3 contracts to avoid affecting the movement of the traveling mechanism 2. After the traveling mechanism 2 moves to other ridges, the lifting mechanism 3 lifts the frame 1 and the traveling mechanism 2 again. The rotating mechanism 4 drives the frame 1 and the traveling mechanism 2 to rotate by a certain angle so that the traveling direction of the traveling mechanism 2 is oriented towards the operation direction. The lifting mechanism 3 lowers the frame 1 and the traveling mechanism 2, and the traveling chassis realizes crossing the ridge and can continue to operate along other ridges. The traveling chassis of the present invention solves the problem of great difficulty in crossing ridges in the prior art for mechanical equipment, is beneficial to improving the operation efficiency, reducing the incidence of equipment failures, and is beneficial to extending the service life of the equipment.

[0051] In this specific embodiment, the telescopic assembly 303 includes two sets of scissor arms 304, and the two sets of scissor arms 304 are symmetrically arranged with respect to the rotation axis of the rotating mechanism 4. When the rotating mechanism 4 drives the frame 1 and the traveling mechanism 2 to move, the force uniformity of the lifting mechanism 3 is improved. In practical applications, the axis of the rotating mechanism 4 can be set in the direction of the center of gravity of the frame 1 to further improve the force uniformity of the frame 1 and the traveling mechanism 2, thereby ensuring the structural stability and working reliability of the traveling chassis.

[0052] In this specific embodiment, the scissor arm 304 adopts a hydraulic, pneumatic or electric drive mode, and an appropriate drive mode can be selected according to the actual working conditions. It should also be explained here that the power sources such as hydraulic, pneumatic and electric power of the scissor arm 304 can choose to share the power source with the working equipment or set up a separate power source. Reasonably selecting and setting the power source is a common means for those skilled in the art and will not be elaborated here.

[0053] In other specific embodiments that can be achieved by the present invention, the bottom struts of the scissor arm 304 move synchronously by means of gear meshing to ensure that the lifting direction is vertically upward, and the gear transmission structure has precise transmission and stable and reliable structure; a sector gear can be used to avoid interference. In practical applications, the scissor arm 304 can also adopt the working mode of a sliding guide rail, with one side strut fixed and the other side strut sliding horizontally in the guide rail groove to complete the lifting action.

[0054] In addition, in other specific embodiments that can be achieved by the present invention, the telescopic assembly 303 can also adopt structures such as telescopic columns and telescopic cylinders to achieve the purpose of driving the lower base 302 to reciprocate vertically and lift the frame 1 and the traveling mechanism 2, and at the same time improve the flexible adaptability of the lifting mechanism 3.

[0055] In this specific embodiment, the lower base 302 includes a bottom wall 305, side walls 306, and extension walls 307. The number of side walls 306 is two groups. The two side walls 306 are perpendicular to the bottom wall 305 and are arranged on both sides of the bottom wall 305. The bottom wall 305 and the two side walls 306 enclose a U-shaped groove-like structure with an opening downward. The bottom wall 305 can contact the ridge. The distance between the two side walls 306 matches the width of the ridge, so that the two side walls 306 can abut against the side surface of the ridge, increasing the contact area between the lower base 302 and the ridge and improving the movement stability of the lifting mechanism 3. In other specific embodiments that can be realized by the present invention, the shape enclosed by the bottom wall 305 and the two side walls 306 can be adjusted accordingly according to the different shapes of the ridges. For example, when the cross-section of the ridge is trapezoidal, the bottom wall 305 and the two side walls 306 can enclose a trapezoidal groove-like structure accordingly. At the same time, the lower base 302 of the present invention is provided with extension walls 307. The extension walls 307 are connected to the ends of the side walls 306 away from the bottom wall 305 and extend in a direction away from the bottom wall 305. The extension walls 307 are arranged parallel to the bottom wall 305. The extension walls 307 correspond to the side walls 306 one by one. The scissor arms 304 are connected to the extension walls 307. The extension walls 307 can contact the ground below the ridge, further increasing the contact area between the lower base 302 and the ground and ensuring the lifting stability and reliability of the lifting mechanism 3. When the cross-sectional shape of the ridge is triangular, directly contacting the bottom wall 305 with the ridge may damage the ridge. At this time, the height of the side walls 306 can be reasonably set so that the extension walls 307 contact the ground beside the ridge, and still can provide stable support for the operation of the lifting mechanism 3, improving the flexible adaptability of the lifting mechanism 3.

[0056] In this specific embodiment, a connecting frame 308 is provided at the bottom of the upper support 301. The scissor arms 304 are connected to the connecting frame 308, which is beneficial to improving the force uniformity of the upper support 301, thereby further improving the working stability of the lifting mechanism 3.

[0057] Specifically, the rotating mechanism 4 includes a rotating inner ring 401, a rotating outer ring 402, and a rotating driver. The rotating inner ring 401 is connected to the upper support 301. The rotating outer ring 402 is rotatably sleeved outside the rotating inner ring 401. The rotating outer ring 402 is connected to the frame 1. The output end of the rotating driver is in transmission connection with the rotating outer ring 402. The rotating driver is fixed on the upper support 301. The rotating driver drives the rotating outer ring 402 to rotate relative to the rotating inner ring 401 to drive the frame 1 and the traveling mechanism 2 to rotate an angle, facilitating cross-ridge operation. In order to ensure the smooth rotation of the rotating mechanism 4, in practical applications, a wear-resistant sleeve or bearing can be provided between the rotating inner ring 401 and the rotating outer ring 402 to improve the working reliability of the rotating mechanism 4.

[0058] In this specific embodiment, the rotary drive uses a worm and worm gear to drive the rotation of the rotary outer ring 402, which can achieve a large transmission ratio, and has a compact structure and stable transmission. In addition, the worm and worm gear transmission structure has self-locking property, which is beneficial to further improve the operation safety of the rotary mechanism 4. In practical applications, other transmission structures such as gear racks can also be used to meet different transmission requirements and adapt to various operating conditions.

[0059] The walking chassis of the present invention is applicable to various operating devices such as planting and harvesting. Economic crops such as tobacco leaves, cotton, and sugarcane need to be ridged and cultivated on the ridges. During harvesting, the walking mechanism 2 generally walks at the bottom of the ridge. After one ridge operation is completed, the resistance for crossing the ridge and turning is relatively large. The lifting mechanism 3 is used to lift the walking mechanism 2 to a certain height, and the rotary mechanism 4 is used to rotate the frame 1 and the walking mechanism 2 to achieve crossing the ridge operation, reduce the difficulty of crossing the ridge operation, and at the same time can achieve a small turning radius, avoid the problem of derailment of the crawler-type walking mechanism 2, which is beneficial to improve the operation efficiency, reduce the occurrence of operating device failures, can adapt to the operating scenarios of small plots in the south, and improve the flexible adaptability of the walking chassis.

[0060] Embodiment 2

[0061] This embodiment provides a walking chassis, wherein the lower base 302 is detachably connected to the telescopic assembly 303, which is convenient to select different types and specifications of the lower base 302 according to different operating requirements.

[0062] In the walking chassis of this embodiment, during the lifting process, in order to prevent the lower base 302 from sinking into the muddy land and unable to complete the lifting, various lower bases 302 with different structures can be set to increase the contact area between the lower base 302 and the ground and improve the lifting reliability.

[0063] In other specific embodiments that can be implemented by the present invention, the lower base 302 adopts a foldable structure. The lower base 302 includes a telescopic framework and a covering film. The telescopic framework can be unfolded and folded. The covering film is wrapped outside the telescopic framework. The covering film is made of a flexible material or an elastic material. The telescopic assembly 303 passes through the covering film and is connected to the telescopic framework. After the telescopic framework is unfolded, it can increase the contact area between the lower base 302 and the ground, avoiding the problem that the lower base 302 sinks into the ground during the lifting process and cannot lift the frame 1 and the traveling mechanism 2. Especially in a muddy working environment, it further improves the adaptability of the walking chassis to various different working conditions. Wrapping the covering film outside the telescopic framework improves the structural integrity of the lower base 302 and ensures the working reliability of the lower base 302. After the walking chassis has straddled the ridge or completed the lifting, the telescopic framework can be retracted to avoid affecting the normal operation of the walking chassis. Among them, the specific structure of the telescopic framework can adopt a parallelogram telescopic structure or an umbrella-shaped telescopic structure, etc. Reasonably setting the specific structure of the telescopic framework so that it can be unfolded and folded is a common means for those skilled in the art and will not be elaborated here.

[0064] The other structures of the walking chassis in this embodiment are the same as those in Embodiment 1 and will not be elaborated here.

[0065] Embodiment 3

[0066] This embodiment provides a working device, including the walking chassis of Embodiment 1 or Embodiment 2.

[0067] The working device of the present invention can be a planting, harvesting, etc. device. Other components are carried on the frame 1 to meet various working requirements. The walking chassis is used to complete the ridge-crossing operation of the working device, improving the working efficiency.

[0068] In practical applications, the traveling mechanism 2 adopts a crawler structure or a wheeled structure to meet the traveling requirements of different working devices and improve the adaptability of the working device to different types of fields.

[0069] Embodiment 4

[0070] This embodiment provides a working method, using the walking chassis of Embodiment 1 or Embodiment 2, including the following steps:

[0071] When the walking chassis straddles the ridge, the telescopic assembly 303 extends. After the lower base 302 contacts the top surface of the ridge, the frame 1 and the traveling mechanism 2 are lifted, and the traveling mechanism 2 is separated from the field ground and higher than the top surface of the ridge;

[0072] The rotating mechanism 4 works, driving the frame 1 and the traveling mechanism 2 to rotate a certain angle. Then the lifting mechanism 3 works, the telescopic assembly 303 shortens, the traveling mechanism 2 contacts the top surface of the ridge, and the lower base 302 is separated from the top surface of the ridge;

[0073] The traveling mechanism 2 drives the frame 1, the lifting mechanism 3, and the rotating mechanism 4 to move to other ridges.

[0074] The lifting mechanism 3 works, the telescopic component 303 extends, the lower base 302 contacts the top surface of other ridges, and lifts the frame 1 and the traveling mechanism 2, and the traveling mechanism 2 disengages from the ridge and is higher than the top surface of the ridge.

[0075] After the lifting mechanism 3 rotates a certain angle, the telescopic component 303 shortens, the traveling mechanism 2 contacts the bottom of the ridge, and the lower base 302 separates from the top surface of the ridge.

[0076] Adopting the operation method of the present invention can conveniently achieve cross-ridge operation and improve the field operation efficiency.

[0077] It also needs to be explained here that when the rotating mechanism 4 works and drives the frame 1 and the traveling mechanism 2 to rotate, the rotation angle is subject to the suitability of the traveling chassis to cross the ridge, and this is the first rotation; when the cross-ridge operation is completed, when the rotating mechanism 4 works and drives the frame 1 and the traveling mechanism 2 to rotate, the rotation angle is subject to the suitability of the traveling chassis to continue the operation, and this is the second rotation; among them, the second rotation can rotate in the opposite direction to the first rotation or in the same rotation direction as the first rotation, and the specific rotation angle and rotation direction can be adjusted according to specific operation requirements.

[0078] Embodiment 5

[0079] This embodiment provides an operation method, using the traveling chassis of Embodiment 1 or Embodiment 2, which specifically includes the following steps:

[0080] Step 1, the lifting mechanism 3 extends. After the lower base 302 contacts the upper surface of the ridge, the driving frame 1 and the traveling mechanism 2 are lifted as a whole, and the traveling mechanism 2 disengages from the bottom of the ridge and is higher than the ridge surface, as Figure 6 shown.

[0081] Step 2, the lifting mechanism 3 rotates 90 degrees, as Figure 7 shown.

[0082] Step 3, the lifting mechanism 3 descends. After the lower base 302 disengages from the upper surface of the ridge, the traveling mechanism 2 contacts the upper surface of the ridge, and the traveling mechanism 2 is driven to move the frame 1 and the traveling mechanism 2 to above the next ridge, as Figure 8 shown.

[0083] Step 4, the lifting mechanism 3 extends. After the lower base 302 contacts the upper surface of the ridge, the driving frame 1 and the traveling mechanism 2 are lifted as a whole, the traveling mechanism 2 disengages from the bottom of the ridge and is higher than the ridge surface, and the lifting mechanism 3 rotates 90 degrees, as Figure 9 shown.

[0084] Step Five: After the lifting mechanism 3 shortens and the lower base 302 disengages from the ridge surface, the traveling mechanism 2 contacts the bottom of the ridge. Then drive the traveling mechanism 2 to start the operation on the next ridge, as Figure 10 shown.

[0085] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
