Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular, to a direct-seeding machine for dry paddy fields with synchronous film covering, hole seeding, and hole irrigation for rice.

Background Art

[0002] Due to climate change and the continuous increase in the consumption of industrial and urban water, the contradiction between the originally limited water resources and the use of agricultural water is becoming increasingly serious. Drought tolerance, water conservation, green, high yield, and high-efficiency cultivation have become the trends of modern agricultural development. The synchronous film covering, hole seeding, and hole irrigation direct-seeding cultivation for dry paddy fields of rice is a cultivation mode with drought tolerance, water conservation, fertilizer reduction, green, high yield, and high efficiency, and has important significance for the development of the rice industry and food security in arid and dry areas.

[0003] A duckbill seeder is a planting machine for sowing crop seeds. The duckbill seeder has characteristics such as uniform seeding, consistent depth, stable row spacing, and seed saving. For the conventional duckbill seeder, when sowing on the upper surface of the film, since the roller of the duckbill seeder is made of hard plastic, during sowing, the smooth outer wall of the roller contacts the film, and slippage displacement easily occurs during the rolling process, resulting in misalignment between the film holes and the seed holes, which has a serious impact on seed germination and seedling emergence. It is difficult to inject water during the direct-seeding process of dry paddy fields with film covering and hole opening, a large amount of weeds grow in the soil trenches between the films, water and fertilizers cannot be supplied quickly, and there are problems such as low germination rate and seedling emergence rate, poor growth status, and low yield.

[0004] Therefore, the present invention provides a duckbill-type film covering anti-slip fixed seeding device and its direct-seeding machine for dry paddy fields of rice.

The water enters the water wheel 9003 through the through hole on the water supply steel pipe 9002 and finally enters the seeding holes through the water supply holes 9004 on the water wheel 9003.

[0051] In this way, the problem of misalignment between the film holes and the seed holes in the direct seeding of paddy rice on dry fields with film covering and hole punching is effectively solved. By means of soil pressing before seeding, improvement of the seeding wheel 8005, and pressing of the water wheel 9003, the stability of the film position is guaranteed, the overlap between the film holes and the seed holes is realized, and the seeds germinate from the film holes and emerge as seedlings.
