Agricultural vehicle

Abstract

The invention belongs to the field of agricultural vehicles, in particular to an agricultural vehicle used for farming and running in a field. The agricultural vehicle comprises a main frame, and a front wheel assembly, a rear cradle assembly, an engine, an oil tank, a pedal assembly and a gear mechanism assembly which are arranged on the main frame, wherein the rear cradle assembly comprises a rear axle assembly and a rear cradle; the rear axle assembly comprises a rear axle; two ends of the rear axle are provided with connecting disks connected with rear wheels; the middle of the rear axle is provided with a brake mechanism and a chain wheel mechanism; the chain wheel mechanism is connected with the engine through a chain wheel; the rear axle is connected with the rear cradle through a regulating mechanism at axle journals at two ends; the regulating mechanism comprises an eccentric bearing block and two pieces of hoops; one piece of hoop is fixed on the rear cradle and is connectedwith the other piece of hoop through a fastener; and the eccentric bearing block is fixed by the two pieces of hoops through the fastener. The agricultural vehicle has the advantages that: the rear axle can be regulated to fulfill the aim of regulating the chain wheel, so that the tightness of the chain can be regulated to keep the stable work and running of the vehicle, the working efficiency isimproved and the service life is prolonged.

Problems solved by technology

[0002] At present, the structures of three-wheeled tractors, walking tractors and small four-wheeled tractors are primitive and backward, with single working performance and particularly poor safety performance

The three-wheeled tractor is a simple transport model, and its safety performance is very poor. Walking tractors can both transport and farm, but because they are in the opposite direction, they are not satisfactory in terms of transport and farming. Driving is like juggling. The field is like training cattle. In the process of farming, some drivers have been injured by rotary tillers, which is very harmful.

Small four-wheeled tractors have bent over steering and hard transmission. When transporting goods, driving is particularly strenuous and unsafe. During climbing and downhill, driving is difficult due to bending over and steering, which often leads to car accidents. Connecting rotary tillage After the machine, the gravity is unbalanced, making the front wheels lighter, difficult to control the direction, and inconvenient to turn

The above three models have great safety risks, and at the same time, they are inconvenient and uncomfortable to use.
