Farmland rotary tillage device and method

Abstract

The invention discloses a farmland rotary tillage device and method, and relates to the technical field of farming equipment and method.According to the farmland rotary tillage device and method, a main shaft is driven through transmission connection between the main shaft and a main shaft box on a rack, an auxiliary shaft is arranged on the main shaft in a sliding mode, a main cutter head is fixedly arranged on the main shaft, and an auxiliary cutter head is arranged on the auxiliary shaft; therefore, the distance between the main cutter head and the auxiliary cutter head can be adjusted, and the axial density of the rotary blades on the rotary tillage harrow can be adjusted. A hydraulic distance adjusting mechanism matched with the auxiliary shaft is arranged, so that the distance between the main cutter head and the auxiliary cutter head is mechanically adjusted, the control is more accurate, and the manpower is saved; according to the method, the land airing time can be greatly shortened, the autumn planting time is greatly advanced, the wheat head growing rate is increased, and the phenomenon that the cost is increased due to the increase of the seeding rate is avoided; the problems that the airing time is long when the soil humidity is high before autumn sowing, and the leveling effect of an existing rotary tillage device and an existing rotary tillage method on a farmland with the high humidity is poor are solved.

Description

technical field [0001] The present invention relates to the technical field of farming equipment and methods, in particular to a farmland rotary tillage device and method. Background technique [0002] Most of the land in North China is allocated by households. Due to the small plot area of ​​each household, small and medium-sized rotary tillage harrows are mostly used for farmland cultivation. The rotary tillage harrows have the advantages of low cost and fast cultivation speed. The power requirement of the mounted tractor is low, and it is especially suitable for the use of small farmland in my country. The farmland in northern my country is mostly planted in the form of corn or soybean followed by wheat for two seasons a year. After the autumn harvest, it is necessary to carry out the steps of rotary ploughing and leveling the land before wheat planting. However, in recent years, the weather has been abnormal, and abnormal rain has often occurred, especially In low-lying a...
