Description

Ridging, film covering and drip irrigation integrated seeder for dry farming of rice

Technical Field

The utility model relates to special agricultural mechanical equipment, in particular to a ridging, film covering and drip irrigation integrated seeder for dry farming of rice.

Background

Rice is one of three main grain crops in China, and has important roles in guaranteeing grain safety. In recent years, due to a plurality of factors such as lack of water resources, atrophy of planting areas of staple grain crops, lack of rural labor force and the like, large potential risks exist in rice planting in China, and therefore, exploration of rice planting in dry lands has great significance.

The existing agricultural machinery is various and is divided into rotary tillers, seeding machines, ridging devices, fertilizing devices, film covering devices and the like according to different requirements, the traditional agricultural machinery is special machinery for a certain link of agricultural production, the functions of the traditional agricultural machinery are single, the agricultural machinery can be prepared uniformly, the agricultural production cost is greatly increased, and various limitations exist in the production process. For example, the traditional film laminating machine can not synchronously perform ridging, and the ridging of cultivated lands is an important measure for increasing the yield, has various advantages of increasing the thickness of cultivated layers, improving the ground temperature, increasing the soil fertilizer and water retention capacity, resisting drought and preventing waterlogging, facilitating field management (such as intertillage and pesticide spraying) and the like, and particularly has positive effects on irrigation and drainage and promoting rice growth in areas with more rainwater in the south. For another example, the traditional rotary cultivator is only used for carrying out rotary tillage and soil loosening on cultivated lands, generally has no ridging function, and a special ridging device is needed for ridging the cultivated lands, and then a film covering device is adopted for mulching film laying, so that the production process is increased, and the cultivation efficiency of the cultivated lands is reduced. For example, when the traditional film laminating device is used for film laying operation, mechanical operation is mainly used, but manual assistance is still needed for film drawing and soil covering by pressing the ground head, so that the operation efficiency is low. Moreover, the rice drought has higher requirements on the treatment of the early-stage soil, the soil is required to be flat, the soil is deficient in upper part and is solid in lower part, the soil with uneven water distribution on sloping farmland or soil has great limitation, and the soil with insufficient water has limitation on the drought land. In view of the above, the conventional agricultural planting mechanical equipment has a plurality of defects in application to paddy dry land operation, and has great significance in developing a seeder special for paddy dry land cultivation.
