Technical Field

The invention belongs to the technical field of corn protective farming mechanization, and relates to a device for cleaning a planting area under the condition of full straw coverage.

Background

In recent years, the area of corn planted by adopting a protective farming technology in China is continuously increased, but the protective farming technology has certain limiting conditions, the straw coverage requirement is less than 30%, otherwise, a no-tillage planter cannot work normally, the seeding quality is seriously influenced, if the requirement of the protective farming technology is met, most of the excessive straws are subjected to incineration treatment, the environment is seriously polluted, and the straw resources are wasted. Meanwhile, due to wind erosion, water erosion and the use of a large amount of chemical fertilizers, the soil is backward protected, soil hardening is caused, and water and soil loss is serious. Therefore, the technology of returning the whole amount of straws to the field is gradually popularized and expanded, but the returning of the whole amount of straws to the field brings a problem to no-tillage seeding. Aiming at the situation, the straw cleaning 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.

Disclosure of Invention

The invention aims to provide a device which can clean straws covered on a sowing belt in a field and can normally sow the straws.

The invention is realized by adopting the following technical scheme: 1. the main frame of the straw cleaning machine is connected with a front balance weight 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 connecting frame is connected with the main frame through a connecting pin, and the hydraulic rod end of the hydraulic cylinder is connected with the connecting frame. 3. The fixed end of the hydraulic cylinder is connected with the main frame of the straw cleaning machine through a connecting pin, and the oil inlet and the oil outlet of the hydraulic cylinder are connected with a hydraulic system of the tractor through a hydraulic oil pipe. 4. And the two pressure spring rods are respectively arranged on the connecting frame and sleeved with the pressure spring. 5. The tip of the lower frame is punched towards the advancing direction of the tractor and sleeved into the two compression spring rods, the compression spring rods are fixed by the fixing pieces, and the position of the fixing pieces is adjusted to determine the working height of the lower frame. 6. And cleaning disc racks are respectively arranged at corresponding positions of the lower rack, so that the end of the placing bearing is punched to the outer side of the rack. 7. The cleaning disc frame is provided with a cleaning disc. The angle of the cleaning disk rack is adjusted to determine the width of the cleaned straws.

The straw cleaning machine has the advantages of reasonable and compact structure and convenience in installation and use, can be used for cleaning straws in the planting zone of the ground covered by the crushed straws, realizes the purpose of returning the whole straws to the field, cleans up the planting seedbed, and has obvious effects of preserving soil moisture, improving ground temperature and increasing emergence rate.
