Description

Post-positioned four-row adjustable corn straw strip collecting machine

Technical Field

The invention belongs to the technical field of corn protective farming mechanization, and relates to a device for collecting and processing straws covered on the ground surface before planting.

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 strip collecting machine provided by the invention can solve the 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.

Hang the high position behind the lift tractor, the grass dish is hugged in the installation, adjusts backup pad installation hole site, confirms to hug grass dish working angle, adjusts horizontal strut and front strut position respectively, hugs the grass dish on the current support and hugs the grass dish on the horizontal strut at front strut place itself and form a complete clearance straw composite member, and at this moment whole collection strip machine can clear up out complete four blank areas. And the raking plate on the current support and the raking plate on the adjacent transverse supporting beam form a complete straw cleaning combined part, at the moment, the whole strip collecting machine can clean three complete blank belts, 1/2 blank belts are respectively cleaned by the raking plate without forming the combined part on the left and right outermost sides, and the residual 1/2 straws are cleaned out when the machine is required to turn back, so that the finished blank belts are formed by the raking plate and the cleaned 1/2 blank belts. 8. After the whole machine is installed, the hydraulic rod is retracted by the lifting oil cylinder, the unfolding frame of the strip collecting machine is retracted to a vertical position, the machine tool is in a transportation state, the lifting oil cylinder extends out of the hydraulic rod, the unfolding frame of the strip collecting machine is unfolded to a horizontal position, and the machine tool is in a working state.

The straw strip collecting device has the advantages of reasonable and compact structure, convenience in installation and use and wide application range, straw strip collecting treatment is carried out on ground covered by crushed straws, the purpose of returning the whole amount of straws to the field is realized, the seedbed is cleaned, and obvious effects of preserving soil moisture, improving ground temperature and increasing emergence rate are achieved.
