Description

TECHNICAL FIELD

[0001] The present application relates to the field of tractor technology, in particular to a tractor cab operating arrangement and a partitioned tractor. BACKGROUND

[0002] With the rapid development of China's economy and the continuous improvement of the level of agricultural mechanization, the operating personnel have higher and higher requirements for the rationality of the overall arrangement of agricultural machinery and the performance of the cab, and higher requirements for the safety, sealing and comfort of the cab, and the cab technology is continuously developing in the direction of meeting the ergonomics.

[0003] At present, the domestic tractor cowl generally adopts an overall arrangement structure closely connected with the cab or with a small spacing. This arrangement structure horizontally or obliquely arranges the brake operation, clutch operation and steering operation in the front part of the cab, and the connecting pipeline or joint is extended to the rear part of the operating table cowl through the partition. This makes the front cowl of the operating table cowl and the cab unable to achieve complete sealing, causing the heat and noise generated by the engine to be transmitted to the cab through the open seam. At the same time, due to the space limitation of the arrangement structure of the brake, clutch and steering in the rear cowl, the width of the rear cowl cannot be narrowed, and in order to better connect the pipeline in the cab with the machine head and design reasonably, the structure of the traditional cab framework divides the front windshield into three parts, greatly affecting the rain wiper rain area and the lower field of view on both sides. SUMMARY

[0004] To solve the above technical problems, the present application provides a tractor cab operating arrangement and a partitioned tractor, which solves the sealing problem caused by the fact that the brake, clutch and steering pipelines of the current tractor product pass through the front part of the cab rear cowl. At the same time, the cab front windshield has no through hole, realizing the partition of the cowl and the cab, thereby producing better sound insulation and heat insulation effects.
