Description

Front-mounted push-type double-row corn 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 sorting treatment on straws covered on the ground surface before or during 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 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. a 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. The lifting oil cylinder is connected with the machine frame and the upper frame of the dividing machine to control the movement of the working part, and the oil inlet and the oil outlet of the lifting oil cylinder are connected with a hydraulic system of the tractor through a hydraulic oil pipe. 3. The lower frame is connected with the main frame and is connected with the upper frame through a pressure spring shaft and a pressure spring, the lifting oil cylinder is placed at the bottommost part, and the position of the pressure spring is adjusted to enable the lower frame to be in a horizontal working position. 4. The front supports are respectively arranged at two sides of the lower frame, so that the adjusting pin shafts on the front supports face upwards, the distance between the front supports and the central vertical plane is adjusted, and the front supports are symmetrical left and right. 5. Along the advancing direction of the dividing machine, grass holding disc bearing seats are respectively installed, adjusting pin shafts on the grass holding disc bearing seats face upwards, supporting plates are installed, and the front support and the grass holding disc bearing seats are connected and fixed. 6. Installing and raking the grass tray, adjusting the installation hole positions of the supporting plates, determining the working angle of the raking tray, adjusting the position of the front support and determining the returning width of the straws. 7. After the whole machine is installed, the plane formed by the center line of the lifting oil cylinder and the center line of the compression spring shaft can be used as a symmetrical plane, and the whole machine is symmetrical left and right.

The straw returning and seeding machine has the advantages of reasonable and compact structure and convenient installation and use, straw returning treatment is carried out in autumn when ground straws are ground to cover a land, the preposed returning machine and the no-tillage seeding machine are simultaneously arranged on the same tractor during spring seeding, straw returning and seeding operation are completed in one step, the two modes realize full straw returning, and meanwhile, a seedbed is cleaned up, so that obvious effects of soil moisture conservation, ground temperature improvement and emergence rate improvement are achieved.
