Paddy field management machine

Abstract

A paddy field management machine comprises a front vehicle and a rear vehicle. Service braking systems are mounted on the front vehicle and the rear vehicle, the rear vehicle is hinged to the central axis of the front vehicle through a tractor to form an all-wheel drive transport state, and a variable-distance system, a high-ground-clearance all-wheel drive transmission system, a hydraulic control system and a push rod control system are mounted on the front vehicle and the rear vehicle in the all-wheel drive transport state to form a high-ground-clearance all-wheel drive state. The height of a ground clearance and wheel tracks are adjusted in a stepless manner within the design range, the paddy field management machine is particularly applicable to hilly and mountain areas, goes up and down slopes and passes ridges, left and right transmission legs can automatically level through the hydraulic control system when the paddy field management machine runs on a lateral side slope of a mountain land, and crab walking and pivot steering functions can be realized through an electric push rod and out-of-gear structures or wheel steering structures of the transmission legs when the paddy field management machine is operated in a piece of a paddy field. The dragged rear vehicle can be changed, operations such as rotary tillage, seeding and fertilizer application can be performed, and the use efficiency of the paddy field management machine is improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural machine widely used in paddy field plant protection, intertillage and field transportation in hilly and mountainous areas. Background technique [0002] At present, rice production in hilly and mountainous areas has achieved mechanization of cultivation and harvesting. Rice field plant protection and inter-cultivation have developed slowly due to the lack of an ideal field self-propelled chassis. The particularity of hilly and mountainous areas is still in the technological process of solving key mechanical technical problems. Introduction, absorption and innovation stages. Although Japan, South Korea and my country's Taiwan have a large amount of agricultural machinery per unit of arable land, the annual operation volume is small, and the low utilization rate of agricultural machinery is a common problem in their rice production mechanization. [0003] Solving the self...
