Rice and wheat straw returning, rotary tillage, fertilization and seeding combined machine

Abstract

The invention discloses a rice and wheat straw returning, rotary tillage, fertilization and seeding combined machine, and relates to a soil tillage implement. The combined machine comprises a casing and a supporting frame, two rows of bolt holes are formed in the supporting frame, at least two bolt holes are formed in each row, a bolt hole and a flat oval hole are formed in one end of the casing, the bolt hole is close to the end face of the casing, the closest distance between the bolt hole and the flat oval hole is shorter than that between the first row of bolt holes and the second row of bolt holes, the bolt hole in the casing is connected with the first row of bolt holes in the supporting frame through bolts, and the flat oval hole in the casing is connected with the second row of bolt holes in the supporting frame through bolts. The gap and the inclined angle between the casing and a cutter shaft can be adjusted by connecting the casing with different bolt holes in the supporting frame, so that soil is not easily accumulated on the casing, grasses are not easily wound on the cutter shaft, and the soil and the grasses are easily cleaned after the soil is accumulated on the casing and the grasses are wound on the cutter shaft.

Description

technical field [0001] The invention relates to a soil tillage machine tool, in particular to a combined operation machine for returning rice and wheat straw to the field, rotary tillage, fertilization and seeding. Background technique [0002] In the 1990s, the rotary tillage and stubble removal, fertilization and seeding combined operation machine was a new type of soil tillage machine that was gradually developed on the basis of the formed stubble removal machine and rotary tiller according to the needs of agronomy and energy conservation. It can complete stubble removal, rotary tillage, deep fertilization, sowing and compaction operations in one trip, which greatly reduces the compaction of the soil caused by the machine entering and leaving the field many times, improves the comprehensive operating efficiency of the machine, and saves the cost of land cultivation , It reduces the operation cost, and reduces the compaction and damage of the locomotive to the soil. It is ...

AI Technical Summary

Problems solved by technology

However, the patented seeding and fertilizing head cannot adjust the depth of sowing and fertilizing, and the transmission route of seeding and fertilizing is complicated, and the positions of the cutter shaft, the casing and the grille cannot be adjusted, and it is easy to cause the casing to accumulate soil and the cutter shaft to entangle grass. and not easy to clean
