The four-wheel-drive bending and steering tractor has high operating efficiency, good safety, low fuel consumption, easy operation, maintenance and repair, and can meet the needs of various food crops and economic crops. At the same time, with the development of rural water conservancy construction, small-scale construction, and mechanization of loading and unloading sites, construction machinery such as excavators, scrapers, and loaders have been widely used, and their use in modern agriculture has reached a relatively high proportion. Due to the high price of construction machinery, farmers have bought excavators and scrapers converted from small four-wheel tractors one after another. These models are simple in structure and low in price. On the basis of the original small four-wheel tractor, the positions of the seat, steering wheel, clutch, accelerator, and brake can be changed, and the tractor can be turned into an inverted type. transport device or loading device. The four-wheel-drive bending and steering tractor can be expanded into excavators, scrapers, loaders, etc. as long as the interface is replaced, and the operation is simple and convenient. Driven by national policies and market demand for agricultural machinery, adaptable new tractors will become an important force in agricultural cultivation in the future, and the market demand for new tractors shows a trend of increasing year by year. The small and medium-sized tractors with four-wheel drive and waist steering are light in weight, flexible and maneuverable, which can solve the problems of poor terrain adaptability of general tractors and meet the needs of users in hilly areas.

本发明四轮驱动折腰式转向多用途拖拉机具有如下优点： The utility model has the following advantages in the four-wheel drive folded waist type steering multi-purpose tractor:
1.柴油机后置横置，多动力输出口布置：后置有利于拖拉机前部扩展各种功能，如加装农业喷灌系统，扩展水利基本建设的挖斗与推土铲等农业水利机械；有利于折腰转向系统的布置，平衡整车配重；有利于动力系统的配置。为了实现这一目的，布置3个以上的动力输出口，主要有变速箱动力输出口，减速箱两个动力输出口，液压动力输出口。横置柴油机动力传输距离短，方向一致，提高传动效率：由于横置柴油机占用的纵向空间小，可以极大限度缩短了发动机舱的纵向空间，达到整车轻巧、操作灵活。 1. The rear of the diesel engine is placed horizontally, and the arrangement of multiple power output outlets: the rear position is conducive to the expansion of various functions at the front of the tractor, such as the installation of agricultural sprinkler irrigation systems, and the expansion of agricultural water conservancy machinery such as buckets and bulldozing shovels for water conservancy infrastructure; It is beneficial to the layout of the bending steering system and balances the weight of the whole vehicle; it is also beneficial to the configuration of the power system. In order to achieve this purpose, more than 3 power output ports are arranged, mainly including the transmission power output port, two power output ports of the reduction box, and the hydraulic power output port. The power transmission distance of the horizontal diesel engine is short, the direction is consistent, and the transmission efficiency is improved: because the vertical space occupied by the horizontal diesel engine is small, the vertical space of the engine compartment can be greatly shortened, so that the whole vehicle is light and flexible, and the operation is flexible.
2.折腰式液压转向：原地转向力小，转弯半径小，从而克服了由于加大轮胎而影响转弯半径角度，转向灵活，转向平顺性好。 2. The waist-bending hydraulic steering: the in-situ steering force is small and the turning radius is small, thereby overcoming the influence of the turning radius angle due to the enlarged tires, the steering is flexible, and the steering smoothness is good.
3.前后轮径大小相同，四轮驱动：四轮驱动拖拉机采用前后轮径相同、中间布置传动轴的新型前驱动桥(小速比中央传动、防滑差速锁)，使得前桥的农艺地隙和前轮转角增大到后轮驱动拖拉机相近的高度和转角，加上采用液压转向和宽断面轮胎，使牵引附着性能、行间通过性的机动性大为提高。它不仅适用于松软、潮湿土壤上一般耕作，而且适用于中耕、水田作业和带前装载机、收割机械作业。四轮驱动拖拉机可减轻对土壤的压实，四轮驱动拖拉机的滑转损失小，重量分布均匀，可以改善轮辙中土壤的疏松性，有利于保护土壤的团粒结构。四轮拖拉机带前后悬挂、前后动力输出轴及前后液压输出也是拖拉机整体结构形式的新发展。 3. The front and rear wheel diameters are the same, four-wheel drive: the four-wheel drive tractor adopts a new front drive axle with the same front and rear wheel diameters and a transmission shaft in the middle (small speed ratio central transmission, anti-slip differential lock), so that the agricultural land of the front axle The clearance and front wheel rotation angle are increased to the height and rotation angle similar to that of rear-wheel drive tractors, coupled with hydraulic steering and wide-section tires, the traction adhesion performance and the maneuverability of passing between rows are greatly improved. It is not only suitable for general cultivation on soft and wet soil, but also suitable for intertillage, paddy field operations, and operations with front loaders and harvesting machinery. The four-wheel drive tractor can reduce the compaction of the soil. The slip loss of the four-wheel drive tractor is small, and the weight distribution is uniform, which can improve the porosity of the soil in the wheel track and help protect the aggregate structure of the soil. The four-wheel tractor with front and rear suspension, front and rear power output shafts and front and rear hydraulic output is also a new development of the overall structure of the tractor.
