Active anti-blockage type zero-tillage precision seed planter

Abstract

The invention relates to a corn zero-tillage seed planter capable of completing operations of stubble breaking, ditching, fertilizing, earthing, compacting, etc., belonging to the technical field of agricultural machinery. The zero-tillage seed planter comprises a machine frame (1), a fertilizer box (2), a seed box (3), a precision seed metering device (4), a bracket (5), anti-blockage blades (6), a shaft (7), a cutting edge stubble breaking opener (8), ground wheels (9), a double-disc opener (10), a duckbilled unfolding device (11), a seed receiving box (12), and earthing compacting wheels (13). During the working, the ground wheel at one side drives a chain wheel to drive the fertilizer device, the fertilizer falls into a ditch opened by the cutting edge stubble breaking opener, the ground wheel drives the anti-blockage blades to rotate so as to cut straws and weeds in a sliding way, the ground wheel at the other side drives the precision seed metering device by means of chain drive so as to force to open a duckbill to discharge the seeds, then the seeds fall into the ditch by the seed receiving box and a seed discharge pipe so as to realize secondary precision seed discharge, and the seeds are then earthed and compacted by the compacting wheels, in this way, the operations of stubble breaking, ditching, fertilizing, earthing, compacting, etc. are completed.

Description

technical field [0001] The invention relates to a sowing machine, in particular to a corn no-tillage seeder, which can complete operations such as breaking stubble, ditching, sowing, fertilizing, covering soil and suppressing at one time, and belongs to the technical field of agricultural machinery. Background technique [0002] my country is one of the major arid countries in the world. The area of ​​arid, semi-arid and semi-humid arid areas accounts for 52.5% of the country's land area, mainly distributed in 16 provinces, municipalities, and autonomous regions north of the Kunlun Mountains, Qinling Mountains, and Huaihe River. Nine provinces are concentrated in Inner Mongolia, Gansu, Liaoning, Ningxia, Hebei, Shanxi, Shaanxi, Qinghai, and Xinjiang. At present, the area of ​​dry farming agriculture is about 33 million hectares. In the vast northern regions of my country, due to long-term deforestation, improper farming methods, and extensive management, the soil is barren, c...

Problems solved by technology

At present, the known no-tillage seeders mainly use special shovel openers or rotary tillers for ditching and sowing, which disturb the soil greatly, consume a lot of power, and cannot achieve precise sowing, resulting in waste of seeds and cost. In addition, the ditch opener of the no-tillage planter is easy to be entangled with straw and weeds to form a blockage, which affects the quality of sowing
