All-hydraulic four wheel drive four-axis turning corn emasculator

Abstract

The invention discloses an all-hydraulic four wheel drive four-axis turning corn emasculator which comprises a frame assembly, a power device, a hydraulic system, a cutting device, a walking mechanism, a steering mechanism and a control console. Through use of a plurality of innovative technical measures in the aspects of overall structure layout, operation functional part integration, power transmission matching selection and other aspects, whole machine autonomous operation walking, hydraulic driving cutting lifting, rotary folding of both sides of a cutting knife, hydraulic four wheel drive, hydraulic four-axis turning, wheel track dynamic adjustment opposite walking, walking profiling automatic telescoping compensation balance and other technical problems can be solved. The all-hydraulic four wheel drive four-axis turning corn emasculator has the prominent characteristics of advanced technology, reasonable structure, strong passing capacity, small turning radius, high production efficiency, good operation quality, wide application range, and the like, is suitable for leaf removal, emasculation, aeration and photopenetration operation of a large area of corn crops in a late growth stage, and can achieve the good operation effects of promoting early-maturing, increasing thousand seed weight of grains, reducing the moisture content of the grains, and the like.

Description

technical field [0001] This patent relates to an agricultural mechanical equipment, specifically a fully hydraulic four-wheel-drive four-axis steering corn detasseler that independently provides operating power and can perform large-scale and efficient defoliation and detasseling operations on late-growing corn crops. Background technique [0002] my country is a large agricultural country. Corn is an important food crop in my country. The annual sowing area is more than 26 million hectares, ranking second in the world. It plays a very important role in my country's national economy and people's lives, and has been highly valued by governments at all levels. . During the planting process of corn crops, the field management operations in the late growth period have a great impact on the fullness, thousand-grain weight and moisture content of the kernels. The growth and maturity of the corn ear mainly depends on the photosynthesis provided by the four cotyledons adjacent to th...
