Combined operation machine

Abstract

The invention discloses a combined operation machine and relates to the technical field of agricultural machines. The combined operation machine comprises a frame and a farming bracket installed at the tail of the frame through a lifting pull rod. A subsoiler, a rotary blade, a grading dragging plate and a furrow opener are sequentially arranged on the framing bracket from front to back. A fertilizer storage box is installed on the farming bracket and provided with a soil feeding pipe and a planting feeding pipe, wherein the soil feeding pipe extends to the position between the subsoiler and the rotary blade, and the planting feeding pipe extends to the position behind the furrow opener. A seed discharge box is arranged at the position, behind the planting feeding pipe, of the farming bracket, and a soil sealing roller is arranged behind the seed discharge box. A straw smashing device is installed at the front end of the frame. Compared with the prior art, the combined operation machine can complete straw smashing and returning, land subsoiling, rotary tillage, flattening, furrow opening, fertilizer applying and seeding at a time, so that production efficiency is improved substantially; through the combined operation machine, soil is prevented from being compressed repeatedly, so that the ventilation and water permeability of the soil are maintained, and seeds are promoted to sprout and grow.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery manufacturing, in particular to a combined operation machine which integrates various operation functions such as straw crushing and returning to the field, deep plowing, fertilization and sowing. Background technique [0002] The straws and stubbles of crops such as wheat, corn, and rice are left on the land after harvesting, and these straws and stubbles need to be cleaned up when farming in the next season, so as to avoid being entangled with agricultural machinery during mechanical farming operations and affecting their normal work. Increase soil organic matter and improve soil structure. Crop planting needs to carry out operations such as straw crushing and returning to the field, deep loosening of the land, rotary tillage, leveling, running, fertilization, and sowing. The agricultural machinery that can only perform a single operation can no longer meet the needs, and the agri...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a combined operating machine that integrates multiple operating functions such as straw crushing and returning to the field, deep plowing, fertilization, and sowing, so as to solve the problem that the existing combined operating machine can only perform soil loosening, rotary tillage, Leveling, running and fertilizing operations, straw crushing and returning to the field and sowing operations require separate operations to improve production efficiency
