Description

Farmer vehicle suitable for carrying cargo in different terrains Technical Field The invention relates to the technical field of farmer vehicles, in particular to a farmer vehicle suitable for carrying cargo on different terrains. Background Farmers' vehicles are popular names for utility ATVs, which result from their widespread use in farm operations. The multifunctional vehicle is essentially a multifunctional vehicle, and is designed to freely run in complex terrains such as beach, jungle, mountain land and the like due to compact size and strong trafficability. Powerful cargo functions are an important feature of farmer vehicles, which are mainly manifested in several aspects. Many farmer vehicles design an open cargo area at the rear of the vehicle body, such as a light truck or pick-up, to allow easy transport of farm tools, feed or crop. The patent publication number CN223835388U discloses an all-terrain new energy agricultural vehicle, which is combined with a specification and a drawing, and adopts the scheme that the vehicle comprises a vehicle frame, wherein the vehicle frame is sequentially provided with a vehicle head, a cab and a loading carriage from front to back, the loading carriage comprises a carriage underframe, and a carriage body in a square shape is arranged on the carriage underframe, so that the transportation and the carrying are convenient. However, the scheme has certain limitation that 1, when the vehicle is used for unloading on narrow roads or roadsides or sloping fields, horizontal lifting cannot be realized, when loading is carried out, the vehicle is required to bend down or other equipment is required, when unloading is carried out, the vehicle or platform which cannot adapt to receiving materials at different heights cannot be unloaded to the side according to the requirements, and the flexibility is poor. 2. If the loading carriage adopts an electric push rod lifting platform and hydraulic lifting of single-point support, and if the screw rod or the hydraulic cylinder directly lifts the container, the push rod can receive great lateral force when goods are unbalanced or the vehicle shakes. And when the single-point support is adopted, the container is easy to shake, particularly the stability is poor in the lifting process, and the dynamic impact of the goods in the transportation process cannot be resisted. 3. If the loading carriage adopts the scissor fork lifting platform, the lateral dimension of the scissor arm is large, so that the loading carriage is not beneficial to being arranged in a limited space, and the lowest position of a container is limited. In addition, most of the devices can only be lifted horizontally, tilting cannot be realized, even if tilting functions are realized, a complex additional mechanism is required, and dead points can occur at two ends of a travel of a simple link mechanism, so that the devices cannot be started or blocked. Disclosure of Invention The invention mainly aims at the problems of structural design of a loading carriage of a farmer vehicle, and invents the farmer vehicle suitable for carrying cargo in different terrains, so that the horizontal lifting and single-side inclination adjustment of the carriage body are realized, and the cargo carrying adaptability and the loading and unloading convenience of the vehicle under complex terrains are obviously improved. The invention aims at realizing the technical scheme that the farmer vehicle suitable for carrying cargo in different terrains comprises a farmer vehicle body, wherein a carriage body is arranged on the vehicle body of the farmer vehicle body, a bearing shell is further arranged on the vehicle body of the farmer vehicle body, a plurality of jacking connecting rod assemblies and a plurality of screw rod transmission modules are arranged in the bearing shell, each jacking connecting rod assembly is hinged to different positions on the lower surface of the carriage body, a plurality of guide rail bodies are further arranged in the bearing shell, the connecting rod of each jacking connecting rod assembly is slidably arranged on the guide rail body, each guide rail body is provided with a wheel type pushing assembly which axially slides along the guide rail body, the roller body of the wheel type pushing assembly is abutted to the bottom of the connecting rod of the corresponding jacking connecting rod assembly, the nut body of each screw rod transmission module is abutted to the side wall of the wheel type pushing assembly, and each jacking connecting rod assembly is pushed by the corresponding wheel type pushing assembly to change the inclination angle. Preferably, the plurality of screw rod transmission modules, the jacking connecting rod assemblies and the guide rail body are symmetrically arranged in the bearing shell and are symmetrically arranged in the bearing shell with respect to the longitudinal center plane of the bearing shell, and the plurality of jacking co
