A single imitation rice and wheat double-purpose precision hole seeder

Abstract

The invention discloses a single profiling type rice and wheat dual-purpose precision hill seeder. The single profiling type rice and wheat dual-purpose precision hill seeder comprises a profiling mechanism, a ditching mechanism, a hill seeding type seeding mechanism, a soil covering and suppressing mechanism and a power system which provides power for the hill seeding type seeding mechanism; the profiling mechanism comprises a main body frame and a connecting frame; the main body frame is a parallelogram frame structure; connecting positions are hinged; one end of the connecting frame is connected with the main body frame; the other end of the connecting frame is connected with the hill seeding type seeding mechanism; the ditching mechanism, the hill seeding type seeding mechanism and the soil covering and the compressing mechanism are sequentially connected. The single profiling type rice and wheat dual-purpose precision hill seeder has the advantages of achieving synchronous soil crushing, levelling, ditching, precision hill seeding, soil covering and compressing operations, achieving the integral seeding operation in one step, effectively reducing worker labor intensity, improving the production efficiency and the agricultural mechanization level, effectively controlling the seeding depth, guaranteeing seed emergence rate and being uniform and continuous in seeding, reasonable in planting distance, suitable in seeding amount, good in seeding quality and compatible to rice and wheat operation.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a single imitation rice-wheat double-purpose precision hole seeder. Background technique [0002] Rice is the main food crop with the largest planting area, the highest yield per unit area, and the largest total output in my country, and its rice output ranks first in the world. In the past 10 years, the average annual rice output has reached nearly 200 million tons, accounting for 40.5% of the national average annual grain output over the same period and 35.7% of the world's average annual rice output. Rice production is related to my country's food security, agricultural efficiency and farmers' income. The development of mechanization in the planting link of rice production is relatively slow. At present, the mechanization level of rice planting in my country is obviously lagging behind compared with the mechanization of other links. According to statistics, in 2010, the...

Problems solved by technology

[0003] At present, most of the seeders for rice and wheat are only suitable for a single crop. If you change the type of crop, you need to replace the corresponding seeder.

Since the 1960s, my country's rice-wheat direct seeding machine has developed rapidly, mainly used in rice-wheat rotation areas, including Jiangsu, Anhui, Henan, northern Hubei, northern Sichuan and southern Shaanxi, across the east and middle of my country. And in the west, the existing models mostly use the drill sowing technology, which cannot realize the precise hole sowing operation of rice and wheat, the sowing uniformity is poor, and the phenomenon of ridge breakage occurs from time to time; after sowing, rows can be formed, but there is no reasonable spacing between plants, and the use of seed The amount is large; the seed meter is driven by the ground wheel, which is easy to slip and affects the quality of sowing, hindering the progress and development of sowing technology
