Paddy field direct sowing machine synchronous in covering soil, ditching and ridging powered by wheeled tractor

Abstract

The invention discloses a paddy field direct sowing machine synchronous in covering soil, ditching and ridging powered by a wheeled tractor. The paddy field direct sowing machine comprises a frame, a soil covering device, a hydraulic system, a copying device, a ditching and ridging device, a sowing device, a hanging mechanism and a tractor, wherein the tractor is fixedly connected with the frame, the soil covering device is arranged at the front end of the frame, a sowing device is arranged at the rear end of the frame, the copying device is arranged between the soil covering device and the sowing device, the ditching and ridging device is arranged at the lower end of the copying device, and the soil covering device, the copying device and the sowing device are respectively driven by the hydraulic system. The paddy field direct sowing machine disclosed by the invention effectively solves the problems of bad generality of a power chassis, limited working width, high cost, difficult promotion and low production efficiency in prior art, and has the characteristics that structure is simple, operating is convenient, and covering soils, flattening ground, forming water storage ditches are realized, and direct sowing and self-adaptive copying once are precisely carried out.

Description

Technical field [0001] The invention relates to a seeding technology in agricultural machinery, in particular to a direct seeding machine for synchronously covering soil, ditching and ridging a paddy field powered by a wheel tractor. Background technique [0002] Rice ranks first among my country's three major food crops. The annual planting area is about 30 million hectares, accounting for about 30% of the country's cereal planting area. The total rice output is nearly 200 million tons, accounting for more than 25% of the country's total output. Rice production occupies a very important position in my country's food production. Improving the comprehensive production capacity of rice is a long-term strategic goal to ensure food production safety. In recent years, due to the massive transfer of labor, the rice planting area has been decreasing year by year. Improving the level of rice production mechanization has become one of the important measures to increase the rice yield leve...

AI Technical Summary

Problems solved by technology

At present, the mechanization of rice planting has become one of the bottlenecks in the development of mechanization in the whole process of rice production. It mainly uses a lightweight chassis as power, with low power and limited working width. There is still a big gap in production efficiency compared with foreign countries, and the light power chassis is universal. Poor, resulting in higher costs and increased difficulty in promotion
