Problems solved by technology

[0003] 1. Relying on the driver's driving skills and experience for steering operations, the walking accuracy is low when following the cooperative operation of agricultural farming, harvesting and other equipment, and it is impossible to realize fully automated operations
[0004] 2. The steering angle of the steering wheel of the traditional steering system is limited, so that the turning radius of the tractor in the field is large, and the in-situ steering cannot be realized, which makes the operation accuracy low

Embodiment 1

[0032] In the compound steering system of the tractor, the folding steering system 3 is unfolded before the tractor cooperates with the equipment such as agricultural farming and harvesting. The specific process is as follows: the piston rod of the hydraulic cylinder 30 is stretched out, and the outer convex part is pushed through the pin shaft 31-2. 31-1 unfolds the lower end of the rocker arm 31 around the front lower end of the vehicle frame 1 until the independent steering wheel 35 touches the ground, and the traditional steering system 2 is separated from the ground. At this time, the steering of the tractor is realized by the folding steering system 3. The specific process For: the steering hydraulic motor 32 drives the pinion 32-1, and the pinion 32-1 drives the large gear 33-1 with the wheel frame 34 and the independent steering wheel 35 to realize steering. During the steering process, the driving hydraulic motor 34-1 can drive The independent steering wheel 35 rotates...

Embodiment 2

[0035] In the compound steering system of the tractor, before the tractor is transported alone on the road or in the field, the piston rod of the hydraulic cylinder 30 shrinks, and the outer convex part 31-1 is pulled by the pin shaft 31-2 and the lower end of the rocker arm 31 is wound around the vehicle frame. 1. The front lower end is folded into the front mast 11 until the traditional steering system 2 is in contact with the ground, and the independent steering wheel 35 is stored as a spare tire.

[0036] Both ends of the bearing sleeve 31-4 are welded with stiffener cover plates to ensure the bearing strength of the bearing sleeve 31-4; the wheel frame 34 is an L-shaped structure, so that the side of the independent steering wheel 35 is convenient and practical as a spare tire. Disassembly operation.

Abstract

The invention discloses a tractor composite steering system which comprises a frame, a traditional steering system and a folding steering system, the traditional steering system is connected with the frame, and the folding steering system is connected with the front end of the frame in a storable mode, so that the walking precision of a tractor is high when the tractor cooperatively works along with equipment such as agricultural cultivation and harvesting equipment, and the full-automatic operation is achieved; and meanwhile, an independent steering wheel can be stored as a spare tire.

Description

technical field [0001] The invention belongs to the technical field of agricultural transportation equipment, in particular, the invention relates to a compound steering system of a tractor. Background technique [0002] As agricultural transportation equipment, tractors often walk in the field, either alone for transportation operations, or in conjunction with agricultural farming management and harvesting equipment, but the steering method of the traditional steering system of the tractor depends on the driving skills and experience of the driver. The traditional steering system The disadvantages are: [0003] 1. Relying on the driver's driving skills and experience for steering operation, the walking accuracy is low when following the cooperative operation of agricultural farming, harvesting, harvesting and other equipment, and it is impossible to realize fully automated operation. [0004] 2. The steering angle of the steering wheel of the traditional steering system is...
