A multifunctional unit for crushing straw, clearing straw, fertilizing, sowing, and covering straw

Abstract

The invention relates to a fertilization and seeding machine in agricultural machineries and in particular relates to a multifunctional machine set for straw crushing, straw clearing, fertilization, seeding and straw covering. The machine set comprises a tractor, a fertilization machine and a seeding machine from front to back. The machine set is characterized in that: the fertilization machine and the seeding machine are a fertilization and seeding integrated machine; a straw crushing and clearing machine powered by a tractor power output shaft (15) is connected between the tractor and the fertilization and seeding integrated machine; a plurality of straw crushing cutters (2) are radially configured on a horizontal rotary cutter shaft (3) in the straw crushing and clearing machine, an auger (5) is arranged at the back of the straw crushing cutters (2), a fan (4) is configured on the output end, and the straw can be transferred backwards to straw throwing port (12) above the fertilization and seeding integrated machine through a pipeline. According to the machine set, the stress condition of the working part straw crushing cutters is changed during straw crashing, the failure and the operation cost are reduced and the working efficiency is improved, and in addition, the straw crushed by the front straw crushing and clearing machine can directly cover the seeds after fertilization and seeding, the covering effect is good, and working level of straw crushing, straw clearing, fertilizing, seeding and the straw covering is improved.

Description

technical field [0001] The present invention relates to a fertilizing and seeding machine in agricultural machinery, in particular to a machine for fertilizing and sowing crops such as peanuts, corn, soybeans and wheat in the remaining crop straw after the crops are harvested. , sowing, straw covering and other multi-functional operating units. Background technique [0002] Increasing the multi-cropping index is an important measure to solve the shortage of arable land due to overpopulation and little land. In the Huang-Huai-Hai area of ​​my country, after winter wheat is harvested, summer crops such as peanuts, soybeans, or corn will be planted in the next stubble. However, the large amount of wheat straw remaining in the farmland has seriously affected the sowing of next crops such as summer peanuts, soybeans or corn. Farmers often secretly burn the straw and then plant the seeds. However, burning straw will cause serious air pollution, and the government has explicitly b...
