No-tillage fertilizing and seeding machine

Abstract

The present invention relates to a till-less fertilizer-application seeding machine, which comprises a stander, a seed box that is arranged at the upper part of the stander, a fertilizer box, a tongue, a transmission case that can be connected with the output shaft of the engine of a tractor, a plurality of opening shares that are arranged at the bottom of the stander and an earth roller that is arranged at the rear lower part of the stander, wherein, the earth roller is of a cylindrical shape with both ends large and middle part small and is composed of two end surfaces and a curved grid that is fixed between the two end surfaces. The present invention has the advantages that the earth roller is uneasy to be coated with earth, thereby reducing the operation load; moreover, the ridge-forming height is moderate, thereby effectively preventing the wheat from being buried by the earth during the fertilizer application and watering. An earth-breaking wheel can remove the long straw or the winded grasses on the opening shares, thereby guaranteeing the continuity of the operation of the machine, and sufficiently preserving the soil moisture and being easy to roll the earth. The fertilizer application and the seeding are undertaken by different opening shares, thereby effectively preventing the wheat seedling from being burned by the chemical fertilizer.

Description

(1) Technical field [0001] The invention belongs to agricultural machinery, in particular to a seeder for no-tillage fertilization. (2) Background technology [0002] When the traditional wheat no-tillage seeder is sowing, each opener is easily entangled by long strips of straw and weeds, or even blocked, resulting in a large mechanical workload. The soil clods are not broken, so it is not easy to retain moisture and suppress. The smooth surface stick compactor of the traditional model has a large area of ​​contact with the soil, which makes the soil adhesion strong, making the compactor easy to clay, which increases the work load, and the compaction depth is large, and the ridging height is too high, which is easy to cause watering or heavy rain Or when fertilizing, wheat seedlings are buried dead by silt. In addition, when topdressing chemical fertilizers, wheat seedlings are easily buried to death by floating soil raised by fertilizing ditch openers. The traditional typ...

Problems solved by technology

[0002] When the traditional wheat no-tillage seeder is sowing, each opener is easily entangled by long strips of straw and weeds, or even blocked, resulting in a large mechanical workload. The soil clods are not broken, not easy to retain 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 watering or heavy rain. Or when fertilizing, 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
