Abstract

The invention provides a rear-mounted straw cleaning machine with two rows of left and right outward protrusions, which comprises a main frame, a connecting frame, a lower support, a front support, a straw separating disc bearing seat, a pressure spring shaft, a pressure spring, a length adjusting rod, a pressure spring shaft connecting shaft, a lower support connecting shaft, a pressure spring positioning shaft, a right-angle clamp and the like. During operation, the straw separating disc rotates under the action of lateral force in the advancing direction, straw is separated to two sides by the straw separating teeth on the straw separating disc to realize straw cleaning, the working angle of the straw separating disc is determined by adjusting the length adjusting rod, the position of the front support is adjusted, the straw separating disc on the front support and the straw separating disc on the lower support where the straw separating disc is located form a working combination, and the width of a straw cleaning belt is determined. The invention is a breakthrough of the whole-course mechanization technology of protective farming and solves the problem of seeding under the coverage of full straws.

Description

Two lines of evagination formula straw descaling machines about rearmounted

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. two rows of left and right outwards protruding type straw cleaning machine main frames are arranged on a rear three-point suspension of a tractor through suspension points, and the tractor suspension is located at the lowest floating position. 2. The right-angle clamp is used for installing and fixing the connecting frame on the main frame, 3, the left lower support and the right lower support are respectively installed on the connecting frame, the connecting frame and the left lower support and the right lower support are respectively connected into a fixed structure by sleeving the pressure spring and the pressure spring shaft, and the installation position of the pressure spring shaft is adjusted to enable the left lower support and the right lower support to be located at a horizontal working position. 4. The front support is respectively arranged on the left lower frame and the right lower frame, and the adjusting pin shaft on the front support faces upwards. 5. And respectively installing left and right grass dividing disc bearing blocks along the advancing direction of the cleaning machine, enabling adjusting pin shafts on the grass dividing disc bearing blocks to face upwards, respectively installing length adjusting rods, and connecting the front support with the grass dividing disc bearing blocks. 6. The rear of the lifting tractor is hung at the highest position, the grass separating disc is installed, the length adjusting rod is adjusted, the working angle of the grass separating disc is determined, the position of the front support is adjusted, the grass separating disc on the front support and the grass separating disc on the adjacent lower support form a working combination, and the cleaning width of the straw belt is determined.

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.
