Description

Front-mounted push-type single-row and double-row variable straw sorting machine

Technical Field

The invention belongs to the technical field of corn protective farming mechanization, and relates to a device for performing row-grouping treatment on straws covered on the ground surface before or during planting, and the device can perform single-row and double-row change according to the requirement of straw treatment.

Background

In recent years, the area of corn planted by adopting a protective farming technology in China is continuously increased, but compared with part of developed countries, the protective farming technology has certain limiting conditions, the straw coverage cannot exceed 30%, otherwise, a no-tillage planter cannot work normally, the operation quality is seriously influenced, if the requirement of the protective farming technology is to be met, most of the excessive straws are subjected to incineration treatment, the environment is seriously polluted, and the straw resources are wasted. Meanwhile, in China, due to the fact that corn planting and farming modes are lagged behind, excessive development and utilization, wind erosion, water erosion and large-amount use of chemical fertilizers are added, soil hardening is caused due to the fact that a land protection method is lacked, soil organic matters are reduced to be below 2% from 6-8% during reclamation, and water and soil loss is extremely serious. Aiming at the situation, the straw grouping machine provided by the invention can solve the difficult problems. The invention ensures that a clean seeding seedbed is cleaned under the condition of returning the whole straws to the field in a covering manner, so that the subsequent no-tillage seeding can keep higher emergence rate, thereby ensuring stable yield and high yield, solving the problem that the field can not be planted without processing the straws, achieving the most reasonable way of returning the whole straws to the field and really realizing the comprehensive utilization of the straws. The emergence of the invention will certainly greatly promote the rapid development of protective farming.

Disclosure of Invention

The invention aims to provide a device capable of grouping crushed straws in a field according to planting mode requirements.

The invention is realized by adopting the following technical scheme: 1. the main frame of the straw sorting machine is connected with a front counterweight point of the tractor by a U-shaped clamp through a self-made connecting piece (a standard piece cannot be formed due to different tractor manufacturers and models), and the ground clearance of the whole machine is adjusted. 2.
