High ground clearance self-propelled chassis with adjustable wheel tread and wheel tread adjusting method of tractor

Abstract

The invention relates to a high ground clearance self-propelled chassis with an adjustable wheel tread and a wheel tread adjusting method of a tractor. The chassis comprises a carframe, a travelling system, an engine, a horizontal frame system and a wheel tread adjusting system. The horizontal frame system comprises a left horizontal frame connected with a left travelling wheel, and a right horizontal frame connected with a right travelling wheel. The wheel tread adjusting system comprises a left wheel adjusting device and a right wheel adjusting device. The left adjusting device comprises a first connection rod and a first driving piece, one end the first connection rod is hinged with the carframe, the other end of the first connection rod is hinged with the left horizontal frame, and the first driving piece drives the first connection rod. The left adjusting device comprises a second connection rod and a second driving piece, one end the second connection rod is hinged with the carframe, the other end of the second connection rod is hinged with the right horizontal frame, and the second driving piece drives the second connection rod. When the wheel tread of the tractor is adjusted, the left horizontal frame is driven to move horizontally inwards or outwards through the stretching out and the drawing back of a first stretching piece to carry out the adjustment of the left travelling wheel. And / or the right horizontal frame is driven to move horizontally inwards or outwards through the stretching out and the drawing back of a second stretching piece to carry out the adjustment of the right travelling wheel.

Description

technical field [0001] The invention relates to a high ground clearance self-propelled chassis, in particular to a high ground clearance self-propelled chassis with adjustable wheelbase, and also relates to a tractor wheelbase adjustment method. Background technique [0002] In my country, cotton, corn, soybeans, rapeseed and other crops are in the middle and late stages of growth. The existing tractors have a low ground clearance, and the supporting equipment cannot enter the field for operation. Especially when field operations are performed on crops with different row spacings, different wheelbases are required. To cooperate with the equipment, it is necessary to adjust the wheelbase of the equipment. At present, the commonly used wheelbase adjustment methods of general tractors mainly include the hub cover clamping adjustment method, the rack and pinion adjustment method, the helical rack and pinion adjustment method, the helical shaft adjustment method, the spiral slide ...

Problems solved by technology

[0002] In my country, cotton, corn, soybeans, rapeseed and other crops are in the middle and late stages of growth. The existing tractors have a low ground clearance, and the supporting equipment cannot enter the field for operation. Especially when field operations are performed on crops with different row spacings, different wheelbases are required. To cooperate with the equipment, it is necessary to adjust the wheelbase of the equipment

At present, the commonly used wheelbase adjustment methods of general tractors mainly include the hub cover clamping adjustment method, the rack and pinion adjustment method, the helical rack and pinion adjustment method, the helical shaft adjustment method, the spiral slide rail type adjustment method, and the telescopic shaft adjustment method. method and rim web adjustment method, but these adjustment methods generally have a relatively small adjustment range, and the adjustment method is relatively cumbersome
