Rice direct seeder matched with hand stepping type transplanter power chassis

Abstract

The invention belongs to the technical field of agricultural mechanical rice direct sowing and particularly relates to a rice direct seeder matched with a hand stepping type transplanter power chassis. The rice direct seeder comprises the hand stepping type transplanter power chassis, a main support frame, a beam connecting device, a beam, a dovetail groove type row spacing adjustment device, a seed metering device, an elevation profiling floating plate, an auxiliary profiling floating plate, a profiling floating plate penetration angle regulation device, a furrow opener mounting device, a rice seed storage tray device and a chain transmission system. The rice direct seeder has the characteristics of light weight of a machine body, multistage distance adjustment, strong adaptability to road condition, economy, efficiency and the like, realizes height adaptability of precision direct sowing machinery to paddy fields in hilly areas and solves the common problem of non-adjustable row spacing, high cost and difficulty in being adapted to paddy field operation in hilly areas of the existing precision direct seeder.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanized rice direct seeding, and in particular relates to a rice direct seeding machine matched with a power chassis of a walk-behind rice transplanter. Background technique [0002] Rice is the main grain crop in my country, with an annual planting area of ​​about 30 million hectares, accounting for 30% of the national grain planting area; 1.5×10 planting households 8 households, accounting for about 60% of the total number of farmers; the annual total rice output is nearly 200 million tons, accounting for 40% of the country's total grain output. It can be seen that rice occupies an extremely important position in China's food security. However, the mechanization level of rice planting in my country is low, which has become a bottleneck restricting the mechanization of rice production. Therefore, accelerating the development of rice planting mechanization will help increase labor product...

AI Technical Summary

Problems solved by technology

Zhang Guozhong et al. invented a boat-type air-power upright deep-fertilizing rice direct seeding machine (publication number: CN106068819A), which uses a mechanical plowing boat as the power chassis, and the front of the fertilizer discharge device and the rear of the seed metering device balance the center of gravity of the boat, which can realize deep muddy fields. Precise hole sowing of rice and direct and deep application of rice seed fertilizer have good application prospects, but the passability of machines and tools is poor

The above-mentioned machines are difficult to adapt to rice field operations in hilly areas, and it is difficult to meet the demand for sowing density adjustment of double-cropping rice direct seeding in the south. The improvement of the level of mechanized planting has important practical significance
