Combined stalk returning field no-tillage fertilizing and seeding machine

Abstract

The present invention relates to a combined straw-returned till-less fertilizer-application seeding machine, which comprises a straw return device and a disassemble till-les fertilizer-application seeding device that is connected to the back of the straw return device. The present invention has the advantages that the straw returning, the fertilizer application and the seeding can be completed only by rolling the earth with a tractor for one time, thereby being convenient and rapid to use, saving money and tie, avoiding the further hardening of the soil and favoring the growth of the crops; moreover, the straw return device and the till-less fertilizer-application seeding device can be used independently. Moreover, the crushing quality of the straw is good, the wheat can be effectively prevented from being buried by the soil and being burned by the chemical fertilizer, the operation resistant force is small, the operation is continuous and the moisture can be sufficiently preserved.

Description

(1) Technical field [0001] The invention belongs to agricultural machinery, in particular to a seeder combined with straw returning to the field for no-tillage and fertilization. (2) Background technology [0002] At present, there are both straw returning machines and no-tillage fertilizing and seeding machines for agricultural machinery, but there is no model that combines the two. For farmers, although these two machines are very convenient to use alone, they still cost more money and time, and the land has to be pressed twice by tractors, which aggravates the compaction of the land and is not conducive to crop growth. [0003] The invention patent No. 200610059338.X introduces a corn stalk chopping and stubble returning machine, which includes a frame, a gearbox that can be connected with the output shaft of the power machine of the tractor, and a cutting rotary knife driven by the gearbox. Rotary knife, stubble removal rotary knife, upper feeding extrusion wheel, lower...

AI Technical Summary

Problems solved by technology

When working, each opener is easily entangled by long strips of straw and weeds, or even blocked, resulting in a large mechanical load. In severe cases, continuous operation cannot be performed, and the soil clods raised by the opener are not broken Not easy to keep moisture and suppress

The smooth surface stick compactor of the traditional model has a large area of ​​contact with the soil, which increases the adhesion of the soil, makes the compactor easy to clay, and increases the work load. Moreover, the compaction depth is large, and the ridging height is too high, which is easy to cause fertilization and watering. Or when it rains heavily, wheat seedlings are buried to death by silt. In addition, when topdressing chemical fertilizers, wheat seedlings are easily buried to death by floating soil raised by fertilizing ditch openers

Traditional models share a ditch opener for fertilization and seeding, and the sown seeds are too close to the fertilizer, which may cause the problem of burning wheat seedlings
