Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-5 This invention provides a technical solution: a chassis suitable for a salt crushing vehicle in a salt pond, comprising a load-bearing plate 1, suspension structures on the left and right sides of the bottom of the load-bearing plate 1, roller structures connected to the bottom of the suspension structures, a functional seat box 2 located in the middle of the bottom of the load-bearing plate 1, power structures on both sides of the functional seat box 2, the power structures driving the roller structures, a buffer frame 3 located at the top of the load-bearing plate 1, a functional connecting plate 4 located at the top of the buffer frame 3, and a long, narrow cavity with a buffer structure in the middle of the cavity. The load-bearing plate 1, as the basic load-bearing component, has symmetrically arranged suspension structures on its left and right sides at the bottom, which can balance the weight of the entire vehicle and independently absorb the impact from the wheels on both sides. The functional seat box 2, located in the middle of the bottom, has a built-in buffer structure that can buffer concentrated stress from the bottom, preventing the impact from being directly transmitted to the upper functional connecting plate 4. A second buffer interface is formed between the buffer frame 3 and the functional connecting plate 4, achieving a flexible connection between the upper and lower structures. The overall layout achieves triple protection through "bottom suspension - middle buffer - upper flexible connection".

[0038] The roller structure includes a hub block 5, with support rods 6 on the outer side of the hub block 5. Several support rods 6 are connected to wheel rings 7 on their outer sides. Several protrusions 8 are located on the outer wall of the wheel rings 7. A connecting rod 9 is connected to the inner side of the hub block 5. The hub block 5 is connected to the wheel rings 7 via the support rods 6, forming a hollow, lightweight structure that reduces salt mud adhesion. The protrusions 8 on the outer wall of the wheel rings 7 are distributed in a dot matrix or strip pattern to penetrate the soft salt layer or increase the coefficient of friction with crystalline salt, preventing slippage. The connecting rod 9 connects to the drive half-shaft assembly 19 to transmit power.

[0039] The suspension structure includes a link frame plate 10, with spring rods 11 symmetrically arranged on both sides of the top of the link frame plate 10. The top ends of the two spring rods 11 are connected to a shock absorber housing 12. The shock absorber housing 12 is elongated and has a groove on its top, with several shock-absorbing structures inside the groove. The link frame plate 10 serves as the connection medium with the roller structure, and the two symmetrical spring rods 11 provide basic elastic support. The shock absorber housing 12 contains multiple shock-absorbing structures, which can disperse impact forces from different directions and avoid stress concentration. The elongated design facilitates the arrangement of multiple shock absorber units within a limited space.

[0040] The damping structure includes a top pressure block 13 and a bottom pressure block 14. Limiting blocks 15 are located on both sides of the bottom of the top pressure block 13, and a guide post 16 is located in the center of the bottom of the top pressure block 13. The bottom pressure block 14 has cavities on both sides into which the limiting blocks 15 are inserted. A column groove is located in the center of the bottom pressure block 14, and a compression spring 17 is located at the center of the column groove. The top pressure block 13 and the bottom pressure block 14 are slidably guided by the limiting blocks 15 and the guide post 16, and the compression spring 17 provides the main elastic force. The limiting blocks 15, inserted into the cavities of the bottom pressure block 14, limit the maximum compression stroke and prevent the compression spring 17 from being overloaded and damaged. This structure combines guiding, limiting, and elastic reset functions.

[0041] The power structure includes a drive motor 18 and a drive half-shaft assembly 19. The output end of the drive motor 18 is connected to the drive half-shaft assembly 19, which is connected to the roller structure via a constant velocity universal joint at its end. The drive motor 18 and the drive half-shaft assembly 19 are connected to the roller structure via a constant velocity universal joint, which allows the roller to maintain a constant speed power output when the suspension bounces up and down, avoiding the jamming or abnormal noise of traditional rigid drive shafts on the undulating road surface of Yanchi.

[0042] The bottom of the functional link plate 4 is connected to a semi-cylindrical casting block 20. A corresponding semi-cylindrical storage tank is provided inside the buffer frame 3. Several compression springs 21 are installed on the inner wall of the storage tank, with the tops of the compression springs 21 connected to the casting block 20. The semi-cylindrical casting block 20 forms an arc-shaped contact with the storage tank, allowing it to withstand both vertical pressure and horizontal shear force simultaneously. The compression springs 21 are distributed along the inner wall of the storage tank, ensuring that the casting block 20 receives a restoring force when it shifts in any direction. This is suitable for lateral impacts caused by uneven salt layers during salt crushing operations.

[0043] The first buffer structure includes an air pump 22, the output of which is connected to an elastic inflatable structure 23. The elastic inflatable structure 23 can be a series of cylindrical rubber airbags or a single long strip of rubber air cushion. The air pump 22 actively controls the internal air pressure of the elastic inflatable structure 23, thereby adjusting the buffer stiffness. The type of rubber airbag or rubber air cushion can be selected according to different operating loads: cylindrical airbags are suitable for concentrated point-like buffering, while the entire air cushion is suitable for evenly distributed loads. This design gives the chassis adaptive buffering capabilities.

[0044] The functional link plate 4 has symmetrical mounting holes on its top left and right sides, and four mounting screws 24 are provided at the top corners of the functional link plate 4. The mounting screws 24 and mounting holes are used to connect the upper equipment (such as salt crushing rollers, cabs, etc.). The use of screws can increase the threaded connection length, improve tensile and vibration resistance, and is suitable for environments with frequent vibration.

[0045] A suspension structure is symmetrically arranged on the left and right sides of the bottom of the load-bearing plate 1. This suspension structure includes a spring rod 11, a shock-absorbing seat box 12, and an internal shock-absorbing structure (top pressure block 13, bottom pressure block 14, and compression spring 17). Compression spring 17 provides the main elastic force, and the limiting block 15 and guide post 16 form a guiding and limiting mechanism to prevent excessive compression. This design achieves multi-level elastic buffering in the vertical direction, effectively absorbing the alternating impacts of the salt pond's "hard shell-soft bottom." Simultaneously, a buffer frame 3 is set at the top of the load-bearing plate 1. The buffer frame 3 and the functional connecting plate 4 are connected to the compression spring 21 inside the storage tank via a semi-cylindrical casting block 20, forming a novel buffer interface that can be reset in both the lateral and longitudinal directions. This structure allows the chassis not only to absorb vertical impacts but also to resist lateral slippage and torsional stress caused by uneven salt layers. Furthermore, the functional seat box 2 is equipped with an air pump 22 and an elastic inflation structure 23 (cylindrical rubber airbag or long rubber air cushion), which can adjust the buffer stiffness in real time according to the working load: reduce the air pressure to improve flexibility under light load, and increase the air pressure to provide sufficient support under heavy load. Through the four-fold protection of "suspension spring - shock absorption structure - buffer frame - pneumatic buffer", the vibration acceleration of the whole vehicle can be reduced by more than 40%, and the loosening cycle of the upper equipment connecting bolts is extended by more than 3 times.

[0046] By adjusting the internal air pressure of the elastic inflation structure 23 using the air pump 22, the driver can adjust the chassis cushioning characteristics in real time according to the salt layer hardness, vehicle load, or operating speed. For example:

[0047] When breaking up hard, thick salt layers, increase the air pressure to enhance the rigidity of the chassis and ensure the cutting force of the salt-breaking equipment;

[0048] In soft, muddy areas, reduce air pressure to increase cushioning and reduce overall vehicle bumps.

[0049] This adaptive capability is not found in traditional passive suspensions, significantly expanding the applicable scenarios for the chassis.

[0050] The design employs a combination of hub blocks 5, support rods 6, wheel rings 7, and several protrusions 8 on the outer wall of wheel rings 7. The protrusions 8 are distributed in a dot matrix or strip pattern, allowing them to penetrate the hard surface of the salt layer or embed themselves in the soft salt mud, forming a mechanical interlocking force. Compared to ordinary tires, the static friction coefficient on wet, slippery salt surfaces is increased by approximately 60%, and the sliding friction coefficient is reduced by more than 50%. Experiments show that on a 15° slope in wet salt terrain, the salt-crushing vehicle using this roller structure can achieve stable starting and climbing, while traditional tire solutions exhibit significant slippage. Simultaneously, the hollowed-out hub and support rod design reduces the salt mud adhesion area, facilitating self-cleaning and preventing increased weight or dynamic imbalance due to salt accumulation.

[0051] This invention comprehensively solves the problems of poor shock absorption, easy slippage, easy corrosion, and unstable power in the chassis of salt crushing vehicles in existing technologies through the synergistic effect of multiple buffers, anti-slip rollers, corrosion-resistant structure, and stable power transmission. It has significant technological progress and practical value.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics.
