Dry direct-seeding machine for paddy rice

Abstract

The invention discloses a dry direct-seeding machine for paddy rice and belongs to agricultural machinery. The dry direct-seeding machine is characterized in that connecting rods A and B are hinged to a machine frame assembly; a flat drag plate is hinged at the rear end part of the connecting rod A through a rocking rod and is elastically connected with the machine frame assembly through vertical shafts B and C; a ridger, a seed fertilizer furrow opener, a soil coverer and a pressing plate are mounted on the flat drag plate; a disc furrow opener is rotatably assembled on the connecting rod B through a swing rod; a base fertilizer box is communicated with the disc furrow opener through a base fertilizer conveying pipe; a seed fertilizer box is communicated with a seed fertilizer funnel on the flat drag plate through a seed fertilizer conveying pipe; a rolling type soil pulverizing and flattening device is assembled at the lower part of the front side of the machine frame assembly. The dry direct-seeding machine is novel and reasonable in structural design, large in amount of working items, high in working efficiency, good in working quality, reliable in working and low in amount of faults during use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seeder for direct seeding of rice. Background technique [0002] Transplanting or throwing seedlings after rice seedling raising, and dry direct seeding of rice are the three main agronomic techniques in rice planting at present. Since rice dry direct seeding does not require multiple agronomic processes such as seedling raising in advance and field preparation, it has many characteristics such as labor saving, labor saving, water saving, and low operating cost. Especially in recent years, with the improvement of rice dry direct seeding agronomic technology, agricultural With the improvement of technical measures, the rice yield and rice quality of rice dry-seeding operation have been greatly improved, and the area of ​​rice dry-seeding operation has increased. At present, in addition to the semi-mechanized operating tool of the traditional drum sieve rice seeder, wheat seeders a...

AI Technical Summary

Problems solved by technology

At present, in addition to the semi-mechanized operating tool of the traditional drum sieve rice seeder, wheat seeders are mostly used for rice dry seeding operations. Due to differences in water and dry fields and different agronomic requirements, the operation quality of rice dry seeding It cannot be guaranteed, and the operation effect needs to be improved. Therefore, it is imminent to develop a machine tool that can adapt to and meet the requirements of rice dry direct seeding operation.
