Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of new agricultural machinery, specifically to a skateboard-type anti-sink chassis for a farm tillage vehicle. Background Technology
[0002] Agricultural machinery refers to all kinds of machinery used in crop cultivation and animal husbandry, as well as in the initial processing and handling of agricultural and livestock products.
[0003] In agricultural operations, especially with agricultural machinery such as tillers, harvesters, and rice transplanters, vehicles can usually operate normally in shallow mud. However, when encountering deep, muddy terrain, due to low chassis, uneven weight distribution, or insufficient tire traction, they often become stuck and unable to extricate themselves. This not only affects agricultural production efficiency but also increases machinery damage and maintenance costs.
[0004] To address this issue, large, high-chassis agricultural machinery, such as large tractors, has been introduced. While these machines have improved maneuverability in deep, muddy terrain to some extent, their bulky size, complex structure, inflexible operation, and high operating costs make them unsuitable for hilly areas and irregularly shaped small fields. Furthermore, large agricultural machinery can easily damage crops when operating in narrow field spaces, limiting their application. Utility Model Content
[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a skateboard-type anti-sinking chassis for farmland tillage vehicles. This skateboard-type anti-sinking chassis solves the problem that farmland machinery is prone to getting stuck in deep mud, and that large agricultural machinery is unsuitable for small plots of hilly land due to its bulkiness, inflexibility, and high cost.
[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a skateboard-type anti-sink chassis for a farm tillage vehicle is provided, comprising a base plate, a gearbox, and a drive mechanism.

The transmission shaft and the drive shaft are rotatably mounted at both ends of the housing, and the output ends of the drive shaft and the gearbox are connected to the transmission shaft. The drive wheel is coaxially and fixedly connected to the drive shaft. One end of the housing is hinged to the base plate, and the other end of the housing is hinged to one end of the shock-absorbing component. The other end of the shock-absorbing component is hinged to the bracket.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 5 As shown, a skateboard-type farm tillage vehicle anti-sinking chassis includes a base plate 1, a gearbox 2 and a drive mechanism 3. The base plate 1 is a flat plate with a large area and a smooth bottom. A mudguard 15 is fixedly installed at one end of the base plate 1, and the mudguard 15 is inclined and fixedly connected to the base plate 1.
[0029] The gearbox 2 is fixedly mounted on the top of the base plate 1. At least four sets of drive mechanisms 3 are provided and arranged in a matrix on both sides of the top of the base plate 1. The drive mechanism 3 includes a bracket 4, a transmission box 5, a shock absorber 6, and a drive wheel 7. The bracket 4 is fixedly mounted on the top of the base plate 1. The transmission box 5 includes a housing 8, a transmission shaft 9, and a drive shaft 10. The transmission shaft 9 and the drive shaft 10 are respectively rotatably mounted at both ends of the housing 8. The output ends of the drive shaft 10 and the gearbox 2 are both connected to the transmission shaft 9. The drive wheel 7 is coaxially fixedly connected to the drive shaft 10. One end of the housing 8 is hinged to the base plate 1, and the other end of the housing 8 is hinged to one end of the shock absorber 6. The other end of the shock absorber 6 is hinged to the bracket 4.
[0030] The drive mechanism 3 also includes a first sprocket 11 and a first chain 12. The two first sprockets 11 are coaxially and fixedly connected to the output end of the gearbox 2 and the drive shaft 9, respectively. The first chain 12 is arranged between the two first sprockets 11.
[0031] The drive mechanism 3 also includes a second sprocket 13 and a second chain 14. The two second sprockets 13 are coaxially and fixedly connected to the drive shaft 10 and the transmission shaft 9, respectively. The second chain 14 is arranged between the two second sprockets 13, and both the second sprockets 13 and the second chain 14 are located inside the housing 8.
[0032] Specifically, the gearbox 2 receives power input from a power source, such as an engine, and transmits it to the gearbox 2 through a corresponding connection. The gearbox 2 then transmits this power to the drive shafts 9 of multiple drive mechanisms 3 through its output end.
[0033] When the gearbox 2 outputs power, it drives the first sprocket 11, which is fixedly connected to it on the same axis, to rotate. With the help of the first chain 12, the drive shaft 9 rotates accordingly, thus realizing the process of transmitting the power output by the gearbox 2 to the drive shaft 9 in the transmission box 5.
[0034] After the drive shaft 9 rotates, it is connected to the drive shaft 10 through a second sprocket 13 and a second chain 14 located inside the housing 8. During the rotation of the second sprocket 13 on the drive shaft 9, the second chain 14 drives the drive shaft 10, which is coaxially fixed to it, to rotate, thereby further transmitting power to the drive shaft 10.
[0035] The drive shaft 10 and the drive wheel 7 are coaxially fixedly connected. When the drive shaft 10 rotates, it directly drives the drive wheel 7 to rotate. The drive wheel 7 contacts the farmland ground and drives the base plate 1 to move in the farmland. The drive mechanisms 3 on both sides of the base plate 1 can be detached for steering.
[0036] When the two drive mechanisms 3 output power in opposite directions, the tiller can turn around on the spot, improving the tiller's flexibility and adaptability.
[0037] When the tiller is working in deep mud, the large contact area of the base plate 1 with the ground reduces the pressure and prevents the vehicle from sinking further. The smooth surface of the base plate 1 has a low coefficient of friction with the mud, allowing the tiller to glide forward and maintain a certain degree of mobility even in deep mud.
[0038] When the tiller encounters uneven terrain or obstacles, the shock absorber 6 and the hinged connection between the base plate 1 and the transmission box 5 can absorb and disperse the impact force, protecting the drive mechanism 3 from damage.
[0039] The chassis features a skateboard-style design with a large, smooth bottom plate 1, effectively navigating complex terrains such as deep mud and silt, thus solving the problem of agricultural machinery easily getting stuck in such conditions. The split left and right drive mechanisms 3 and the four-wheel or higher drive design enhance the tiller's flexibility and stability, enabling it to easily handle various tillage tasks. Compared to large agricultural machinery, this chassis structure is relatively simple and lightweight, with lower manufacturing and maintenance costs, making it more suitable for the needs of small, hilly fields. This chassis can not only be used as a tiller for farmland but also as an all-terrain transport platform or a chassis for sluggish and desert rescue vehicles, demonstrating broad application prospects.
[0040] refer to Figure 2 As shown, in some specific embodiments, a first hinge seat 16 is fixedly provided on the top of the base plate 1, and one end of the housing 8 is connected to the first hinge seat 16. A second hinge seat 17 is fixedly provided on the top of the other end of the housing 8 and the top of the bracket 4, and both ends of the shock-absorbing component 6 are connected to the corresponding second hinge seat 17.
[0041] When the tiller encounters uneven terrain or reefs, one end of the housing 8 rotates around the first hinge seat 16 to adapt to the changes in terrain. At the same time, the shock absorption assembly 6 provides shock absorption and cushioning between the housing 8 and the support 4, absorbing and dispersing the impact of ground impacts or terrain changes, and protecting the drive mechanism 3 from damage.
[0042] In some specific implementations, the shock absorption assembly 6 includes a hydraulic shock absorber, the two ends of which are respectively connected to the corresponding second hinge seat 17. When the housing 8 is impacted by the ground, the hydraulic shock absorber absorbs and disperses the impact force, protecting the drive mechanism 3 from damage.
[0043] In some specific implementations, the shock absorption assembly 6 includes a spring shock absorber, the two ends of which are respectively connected to the corresponding second hinge seat 17. When the housing 8 is impacted by the ground, the spring shock absorber absorbs and disperses the impact force, protecting the drive mechanism 3 from damage.
[0044] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:
[0045] The power source, such as the engine, first transmits power to the gearbox 2. After receiving the power, the gearbox 2 transmits it to the drive shafts 9 of the multiple drive mechanisms 3 through its output end. This transmission process is achieved through a first sprocket 11 and a first chain 12, which are coaxially and fixedly connected to the drive shaft 9. After receiving the power, the drive shaft 9 further transmits it to the drive shaft 10 through a second sprocket 13 and a second chain 14 inside the housing 8. The drive shaft 10 is coaxially and fixedly connected to the drive wheel 7; therefore, the rotation of the drive shaft 10 directly drives the drive wheel 7 to rotate, thereby propelling the tiller forward.
[0046] The tiller's steering is achieved through a left-right split drive mechanism 3. When the two drive mechanisms 3 output power in opposite directions, the tiller can turn around on the spot, improving its flexibility and adaptability.
[0047] When the tiller encounters uneven terrain or obstacles, one end of the housing 8 rotates around the first hinge seat 16 to adapt to changes in terrain. Simultaneously, hydraulic or spring shock absorbers provide shock absorption between the housing 8 and the support 4. When the housing 8 is impacted by the ground, the shock-absorbing assembly 6 absorbs and disperses the impact force, protecting the drive mechanism 3 from damage.
[0048] The large contact area of the base plate 1 with the ground reduces pressure and prevents the vehicle from sinking further. The smooth surface of the base plate 1 has a low coefficient of friction with muddy ground, allowing the tiller to glide forward in the ground and maintain a certain degree of mobility even in deep mud.
[0049] The shock-absorbing assembly 6 and the base plate 1 are hinged to the transmission box 5, which can absorb and disperse the impact force generated by ground impact or changes in location, protecting the drive mechanism 3 from damage. At the same time, the rotational capability of the box body 8 allows the tiller to better adapt to uneven terrain.
[0050] The chassis structure is relatively simple and lightweight, with low manufacturing and maintenance costs. It can be used not only as a chassis for agricultural tillage vehicles, but also as a platform for all-terrain transport vehicles or as a chassis for rescue vehicles in swamps and deserts, showing broad application prospects.
[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
