Detailed Implementation

[0019] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Embodiment 1 of this utility model: As shown Figures 1-6 As shown, an adjustable leveling chassis is disclosed, including a first leveling mechanism and a chassis body 1; There are two first leveling mechanisms, which are symmetrically arranged at the bottom of the chassis body 1; The first leveling mechanism includes an upper bearing beam 2, a connecting rod 3, a lower bearing beam 4, a leveling component, and a first hydraulic cylinder 5; the upper bearing beam 2 is hinged to the chassis body 1, which allows the first leveling mechanism to rotate at a certain angle with the chassis body 1; the connecting rod 3 is arranged parallel between the upper bearing beam 2 and the lower bearing beam 4; the leveling component is slidably mounted on the connecting rod 3, with the upper end of the leveling component hinged to the upper bearing beam 2 and the lower end hinged to the lower bearing beam 4; The leveling assembly includes a first connecting seat 6, a second connecting seat 7, a first sleeve 8, a second sleeve 9, a first support rod 10, a second support rod 11, a third support rod 12, and a fourth support rod 13. The first connecting seat 6 is fixedly mounted on the lower surface of the upper bearing beam 2 by welding, and the second connecting seat 7 is fixedly mounted on the upper surface of the lower bearing beam 4 by welding. The first sleeve 8 and the second sleeve 9 are slidably fitted onto the connecting rod 3. The connecting rod 3 has a rectangular cross-section. The first sleeve 8 and the second sleeve 9 are adapted to the connecting rod 3, thus limiting the movement of the first sleeve 8 and the second sleeve 9 and preventing them from winding around. The connecting rod 3 rotates; one end of the first support rod 10 is hinged to the first connecting seat 6, and the other end is hinged to the first sleeve 8; one end of the second support rod 11 is hinged to the first connecting seat 6, and the other end is hinged to the second sleeve 9; one end of the third support rod 12 is hinged to the first sleeve 8, and the other end is hinged to the second connecting seat 7; one end of the fourth support rod 13 is hinged to the second sleeve 9, and the other end is hinged to the second connecting seat 7; the first connecting seat 6 and the second connecting seat 7 are both located between the first sleeve 8 and the second sleeve 9; the length of the first support rod 10 is equal to the length of the second support rod 11, and the length of the third support rod 12 is equal to the length of the fourth support rod 13. A retaining ring 14 is fixedly provided on the connecting rod 3. The retaining ring 14 is located directly below the first connecting seat 6, and the retaining ring 14 can limit the first sleeve 8 and the second sleeve 9 in the axial direction of the connecting rod 3.

[0021] To make the first leveling mechanism more stable, each first leveling mechanism is equipped with two sets of leveling components.

[0022] Each of the first leveling mechanisms consists of two first hydraulic cylinders 5. One end of each first hydraulic cylinder 5 is hinged to the connecting rod 3, and the other end is hinged to the lower bearing beam 4. The hinge points of the two first hydraulic cylinders 5 and the connecting rod 3 are located at opposite ends of the connecting rod 3. The first hydraulic cylinders 5 are inclined and symmetrically arranged. Specifically, the two first hydraulic cylinders 5 are symmetrically arranged about a first plane, which is perpendicular to the lower bearing beam 4 and passes through the geometric center of the lower bearing beam 4. By extending and retracting the two first hydraulic cylinders 5, the height of the connecting rod 3 and the lower bearing beam 4 is adjusted, changing the angle between the third support rod 12, the fourth support rod 13 and the lower bearing beam 4. This causes the third support rod 12 to drive the first sleeve 8 and the fourth support rod 13 to drive the second sleeve 9 to slide on the connecting rod 3, further changing the angle between the first support rod 10, the second support rod 11 and the upper bearing beam 2, thereby changing the height of the connecting rod 3 and the upper bearing beam 2, thus amplifying the extension and retraction of the first hydraulic cylinders 5.

[0023] The height adjustment of the two first leveling mechanisms is controlled by the extension and retraction of the first hydraulic cylinders 5 of the two first leveling mechanisms, thereby realizing the adjustment of the chassis ground clearance and lateral leveling.

[0024] Specifically, when the first hydraulic cylinders 5 of the two first leveling mechanisms operate simultaneously and extend and retract by the same amount, the lift of the two first leveling mechanisms is consistent, thereby achieving ground clearance adjustment of the chassis. By controlling the extension and retraction of the two first hydraulic cylinders 5 of one first leveling mechanism to be different from that of the two first hydraulic cylinders 5 of the other first leveling mechanism, a height difference is formed between the two first leveling mechanisms at the bottom of the chassis body 1, thereby achieving lateral leveling of the chassis body 1.

[0025] To ensure the stability of the distance between the two first leveling mechanisms, a second hydraulic cylinder 15 is also included. There are four second hydraulic cylinders 15, arranged in groups of two. The two groups are respectively located at the front and rear ends of the chassis body 1, corresponding to the front and rear ends of the agricultural machinery. One end of the second hydraulic cylinder 15 is hinged to the chassis body 1, and the other end is hinged to the upper load-bearing beam 2. The rotation center line of the second hydraulic cylinder 15 and the upper load-bearing beam 2 is parallel to the rotation center line of the chassis body 1 and the upper load-bearing beam 2.

[0026] It also includes a platform 16 and a second leveling mechanism; the second leveling mechanism includes a third hydraulic cylinder 17; one end of the platform 16 is hinged to one end of the chassis body 1; the third hydraulic cylinder 17 is disposed between the platform 16 and the chassis body 1, one end of the third hydraulic cylinder 17 is hinged to the platform 16, and the other end is hinged to the chassis body 1; the rotation center lines of the platform 16 and the chassis body 1, the rotation center lines of the third hydraulic cylinder 17 and the platform 16, and the rotation center lines of the third hydraulic cylinder 17 and the chassis body 1 are parallel; the rotation center lines of the platform 16 and the chassis body 1 are set along the width direction of the chassis body 1. The width direction of the chassis body 1 is consistent with the width direction of the agricultural machinery.

[0027] Furthermore, a support frame 18 is provided at one end of the chassis body 1, where "one end" refers to the front or rear end of the chassis body 1. One end of the platform 16 is hinged to the end of the support frame 18 away from the chassis body 1. The hinge point between the third hydraulic cylinder 17 and the platform 16 is away from the support frame 18, while the hinge point between the third hydraulic cylinder 17 and the chassis body 1 is close to the support frame 18. The rotation direction of the platform 16 is adjusted by extending and retracting the third hydraulic cylinder 17 to achieve longitudinal leveling of the platform 16.

[0028] Each first leveling mechanism has a traveling mechanism 19 at its bottom. The chassis is driven to move via the traveling mechanism 19. The traveling mechanism 19 can be a tracked mechanism, which is a technology that can be implemented by those skilled in the art and will not be described in detail here.

[0029] The bottom of the chassis body 1 is also equipped with an oil tank 20 and an engine 21. The engine 21 provides power to make the oil in the oil tank 20 enter the first hydraulic cylinder 5, the second hydraulic cylinder 15, the third hydraulic cylinder 17 and the hydraulic motor of the track mechanism to realize ground clearance adjustment, lateral adjustment, longitudinal adjustment and travel.

[0030] This application utilizes a first leveling mechanism to adjust the height of the chassis body 1 above the ground, i.e., to adjust the ground clearance, and also to achieve lateral leveling of the chassis body 1. This prevents the chassis from scraping due to insufficient ground clearance, and avoids the chassis from tipping over due to excessive ground clearance causing a high center of gravity and poor stability. Combined with a second leveling mechanism for longitudinal leveling of the platform, this improves the machine's passability and operational adaptability in complex, undulating terrain.
