Oilseed rape pneumatic type precision combined direct seeding machine with ditch type drag reduction and sorting functions

Abstract

The invention belongs to the technical field of agricultural machinery, in particular to an oilseed rape pneumatic type precision combined direct seeding machine with ditch type drag reduction and sorting functions. The machine comprises a body rack, an air pump, a rotary tillage mechanism, a fertilizer discharging mechanism, a direct seeding mechanism, a ditching mechanism and a land wheel. Compared with the prior art, the machine has the following advantages that the ditching mechanism is additionally arranged between the land wheel and the rotary tillage mechanism so that the ditching mechanism can direct conduct ditching on soft soil obtained after rotary tillage, the ditching resistance is reduced, and the power consumption is reduced; a triangular tooth-shaped protrusion is arrangedat the bottom of a ditching device, the contact area between the ditching device and ditches is reduced, and the resistance is reduced. The machine integrates the procedures of oilseed rape rotary tillage, fertilization, seeding, ditching and the like, the procedures of oilseed rape rotary tillage, fertilization, seeding, ditching and the like can be completed through one-time work, the using quantity of machines is reduced, and the cost and time are saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a pneumatic precision combined direct-seeding machine for rape with ditch-type drag-reducing arrangement. Background technique [0002] Rapeseed is an important oil crop in my country, and its mechanized direct seeding has the advantages of saving man-hours, cost savings, high efficiency, and consistent maturity. The development of a new type of rapeseed direct seeding machine is particularly important. Since rapeseed is mostly planted in the Yangtze River Basin, the rainfall in this area is relatively high, which is not conducive to the growth of rapeseed. Therefore, rapeseed planting requires ditching (box ditch, waist ditch and surrounding ditch, referred to as "3 ditch"). Most of the existing rapeseed direct seeding machines are not equipped with a furrowing mechanism; few of them use a plow-type ditching device combined with a front and rear arrang...

AI Technical Summary

Problems solved by technology

Most of the existing rapeseed direct seeding machines are not equipped with a furrowing mechanism; few of them use a plow-type ditching device combined with a front and rear arrangement of a herringbone shaping device, because the plow-type ditching device is located at the front of the rotary tillage assembly. That is, the power consumption required for use on uncultivated land is high, and the manufacturing cost is increased
