Description

Technical Field

[0001] This invention relates to the field of agricultural machinery chassis structure technology, specifically to a high-passability general-purpose chassis and its agricultural vehicles. Background Technology

[0002] With the continuous improvement of agricultural mechanization, field operation equipment plays an increasingly important role in agricultural production. Various agricultural machines, such as rice transplanters, seeders, and fertilizer applicators, are widely used in field operations in different terrains, including paddy fields and dry land. The chassis of these agricultural machines is the fundamental component of the entire machine, and its performance directly determines the equipment's ability to traverse complex field environments and its operational efficiency. Currently, most agricultural machinery chassis on the market adopt a four-wheel or three-wheel structure, and the power system is usually provided by a single engine, with power transmitted to the drive wheels via a transmission.

[0003] However, existing agricultural machinery chassis still have significant shortcomings in practical use. First, due to the complex and diverse terrain of farmland across my country, including plains, hills, mountains, and different types of paddy fields and dry land, traditional chassis are prone to slipping or getting stuck in muddy, soft, and undulating terrain, resulting in low passability and poor adaptability. Second, most existing chassis are specifically designed for particular models, leading to poor interchangeability between different agricultural machines, low equipment utilization, and waste of resources and energy. Furthermore, many chassis are heavy and bulky, which not only hinders transportation and relocation but also causes excessive compaction of farmland soil, affecting crop growth. Summary of the Invention

[0004] The purpose of this invention is to provide a high-passability general-purpose chassis and its agricultural vehicle to solve the problems mentioned in the background art.

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.

[0015] Please see Figures 1-5 The present invention provides a technical solution: A high-pass-rate universal chassis, as per the instruction manual. Figure 1 As shown, it includes: The frame assembly 1 serves as the skeleton of the entire machine, used to support and connect other components. Specifically, the frame assembly 1 includes a frame assembly 11 and a steering control assembly 12. The frame assembly 11 is a welded frame structure with sufficient rigidity and strength. The steering control assembly 12 is located at the front end of the frame assembly 11 and is used to control the front axle assembly 2 for steering. The steering control assembly 12 is a double rocker arm steering gear. The steering control assembly 12 is connected to the steering column and the steering wheel in the cab of the agricultural machinery through the steering column (neither the steering column nor the steering wheel is shown in the attached drawings of the instruction manual).

[0016] A front axle assembly 2 is disposed on the front side of the frame assembly 1. The front axle assembly 2 supports the front wheel assembly 24 and provides steering functionality. The front axle assembly 2 includes an auxiliary powertrain 21, a bracket assembly 22, a front drive assembly 23, a front wheel assembly 24, a steering assembly 25, and an outer casing assembly 26. The auxiliary powertrain 21 provides auxiliary driving force to the front wheel assembly 24. In use, the auxiliary powertrain 21 can be an electric motor or a small hydraulic motor. In this embodiment, it is an electric motor (powered by a battery). The electric motor can respond quickly when assisting steering. The bracket assembly 22 is connected to the steering assembly 25. The steering assembly 25 is connected to the frame assembly 11, and the steering assembly 25 and the steering control assembly 12 are connected by a power connection (e.g., through a steering tie rod or steering hydraulic circuit). The lower part of the bracket assembly 22 is connected to the front wheel assembly 24. The auxiliary power assembly 21 is mounted on the bracket assembly 22. The input end of the front drive assembly 23 is connected to the auxiliary power assembly 21, and the output end is connected to the front wheel assembly 24. The front drive assembly 23 can be a sprocket and chain mechanism, a gear mechanism, or a pulley mechanism. In this embodiment, the front drive assembly 23 is a sprocket and chain mechanism to achieve reliable power transmission. The outer cover assembly 26 covers the auxiliary power assembly 21 and the front drive assembly 23 to provide dustproof, waterproof, and protective functions.

[0017] The generator-transformer integrated assembly 3 is located in the middle of the frame assembly 1. The generator-transformer integrated assembly 3 is used to generate and transmit power. The generator-transformer integrated assembly 3 includes an engine assembly 31 and a transmission assembly 32. The engine assembly 31 is located on the frame assembly 11. In actual use, the engine assembly 31 can be a diesel engine or a gasoline engine. In this embodiment, it is a diesel engine (more suitable for heavy-duty field operations). The power output end of the engine assembly 31 is connected to the transmission assembly 32. The transmission assembly 32 is used to adjust the speed and torque input to the rear axle assembly 4. In actual use, the transmission assembly 32 can be a continuously variable transmission (CVT) or a mechanical stepped transmission.

[0018] The rear axle assembly 4 is located at the rear of the frame assembly 1 and is connected to the generator-transformer integrated assembly 3 for power connection. The rear axle assembly 4 includes a rear axle drive assembly 41 and a rear travel assembly 42. The two output ends of the transmission assembly 32 are respectively connected to the rear axle drive assembly 41, and the rear travel assembly 42 is respectively connected to the outside of each rear axle drive assembly 41. The rear axle drive assembly 41 may contain components such as a differential and half shaft. The rear travel assembly 42 may be equipped with rubber tires with anti-slip plates to adapt to different field conditions.

[0019] Working principle: During operation, the power output from the engine assembly 31 is adjusted by the transmission assembly 32 and drives the rear axle transmission assembly 41 to rotate the rear travel assembly 42, achieving rear-wheel drive. At the same time, the power output from the auxiliary power assembly 21 is transmitted to the front wheel assembly 24 through the front transmission assembly 23, giving the front wheels auxiliary driving force. When the chassis travels on muddy or soft terrain, the front wheel auxiliary driving force can effectively prevent the front wheels from getting stuck or slipping, significantly improving the overall passability. When turning, the driver operates the steering control assembly 12 through the steering wheel, thereby controlling the steering assembly 25 to drive the support assembly 22 and the front wheel assembly 24 to turn, achieving steering.
