Trench digging and soil covering mechanism for direct seeding in dry rice fields

Abstract

The invention discloses a trench digging and soil covering mechanism for direct seeding in dry rice fields. The trench digging and soil covering mechanism comprises a rice direct seeding rack installed on a mini-tiller, wherein a plurality of grain hoppers adjustable in intervals in a left-and-right direction are arranged on the upper part of the rice direct seeding rack; the bottom of the rice direct seeding rack is provided with a plurality of openers which are adjustable in position and correspond to the plurality of grain hoppers; a soil covering rack horizontally arranged along a left-and-right direction is mounted behind the plurality of openers and is in erection joint with the rice direct seeding rack via a left connecting rod and a right connecting rod; the bottom of the soil covering rack is provided with a plurality of pairs of soil covering plates which are adjustable in position and correspond to the plurality of openers; the rice direct seeding rack is longitudinally andobliquely provided with a plurality of pairs of grain discharging grooves which are adjustable in position and correspond to the plurality of grain hoppers; the front upper end of each grain discharging groove is located below the discharge outlet of a corresponding grain hopper; and the rear lower end of each grain discharging groove is located between a corresponding opener and corresponding soil covering plates. The trench digging and soil covering mechanism provided by the invention has high reliability and ideal soil covering effect in direct seeding of dry fields, and allows rice directseeding technology to be normally applied in arid seasons.

Description

technical field [0001] The invention relates to the structure of agricultural machinery components, in particular to a ditching and soil covering mechanism for direct seeding of paddy fields. Background technique [0002] At present, the rice planting mode is mainly to sow first and then transplant the rice seedlings. The whole process of rice planting has many procedures, which has high requirements for planting agronomy and high requirements for mechanical equipment. [0003] For this reason, numerous agronomists and agricultural research institutes have worked out the rice direct seeding technology, and have developed the rice direct seeding machine device and used on the rice transplanter on the basis of the rice direct seeding technology. [0004] However, in the actual application process, due to the lack of a mechanism that can be used for dry field direct seeding technology, only paddy field direct seeding can be realized, and the effect of dry field direct seeding i...

Problems solved by technology

[0004] However, in the actual application process, due to the lack of a mechanism that can be used for dry field live broadcast technology, only paddy field live broadcast can be realized, and the effect of dry field live broadcast is poor, mainly due to the inability to effectively cover the sown grain seeds during dry field live broadcast.

[0005] As a result, rice planting is extremely susceptible to delays in farming time due to factors such as weather and water sources
