Description

Seedbed strip arrangement and seed ditch forming combined operation monomer

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a combined operation monomer for finishing various bed strips and extruding and forming seed ditches.

Background

The traditional strip-type seed furrow opener mainly comprises a single-disc opener, a double-disc opener and a boot-type opener, wherein the boot-type opener adopts a relative movement ground sliding principle to finish strip-type seed furrow forming operation; the single-disc furrow opener and the double-disc furrow opener complete the furrowing operation of the strip seed furrows by adopting a rolling cutting principle, and are still applied to agricultural mechanized operation at present based on a plurality of advantages of small operation resistance, low power consumption, small seed furrow width and the like. However, in the practice of production and use for many years, the single-disc and double-disc furrow openers only have the function of ditching for cutting strip seed furrows in soil, do not have the function of processing and finishing strip soil on two sides of the strip seed furrows and soil in the furrows, have high soil hardness and are not loose, and influence the germination, growth and development of seeds. In recent years, with the development of science and technology, agricultural users urgently need to improve the quality of strip seedbeds and seed ditches in processing and forming so as to meet the needs of agricultural production.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and researches and designs a seedbed strip arrangement and seed furrow forming combined operation monomer with a new structure by combining the current actual requirements on strip seed furrow processing, so as to achieve the purposes of good quality of seedbed strips and seed furrows, high operation efficiency and provision of high-quality seedbed conditions for growth and development of crops.

The invention aims to realize that triangular star frames are fixedly arranged on two opposite side parts of a single frame symmetrically, positioning and supporting planet gears are respectively and rotatably arranged on the upper end parts of the two triangular star frames which are arranged oppositely, planet gear shafts are respectively and rotatably arranged on two side parts of the lower ends of the two triangular star frames which are arranged oppositely, sun gears are respectively and rotatably arranged on the central parts of the two triangular star frames which are arranged oppositely, the sun gears are meshed with the planet gears of the planet gear shafts and the positioning and supporting planet gears, inner gear rings are sleeved and arranged on the outer side parts of the planet gears of the positioning and supporting planet gears and the planet gears of the two planet gear shafts in a mutually meshed way, corrugated disc coulters are fixedly arranged on the inner gear rings, a soil breaking knife roller and a seed furrow extrusion forming roller are respectively used for supporting the planet gear shafts which are arranged oppositely on the front side parts of the lower ends of the triangular star frames and the planet gears which are arranged oppositely on the rear side parts of the lower ends of the triangular star frames On the wheel shaft, a seedbed strip arrangement and seed ditch forming combined operation unit is formed.

The invention has novel, unique, reasonable and compact structure, good quality of seedbed strip arrangement and seed furrow forming, high operation efficiency, reliable use and less faults, and provides good seedbed strip and seed furrow conditions for seed growth and development.

Description of part numbers in the figures:

1. the device comprises a single frame, 2, a triangular star frame, 3, an inner gear ring, 4, a positioning support planetary gear, 5, a sun gear, 6, a corrugated disc coulter, 7, a planetary gear shaft, 8, a soil breaking knife roller, 9 and a seed furrow extrusion forming roller.

Detailed Description

The inventive embodiments of the present invention are described in detail below with reference to the accompanying drawings. A kind of bed strip arrangement and seed furrow shaping combined operation monomer, including ripple disc coulter 6, fix triangle star-shaped shelf 2 on the opposite both sides of the monomer frame 1 symmetrically each other, install the location support planetary gear 4 on the upper end position of two triangle star-shaped shelf 2 that are disposed relatively rotatably respectively, install the planetary gear shaft 7 on the both sides position of lower end of two triangle star-shaped shelf 2 that are disposed relatively rotatably respectively, install the sun gear 5 on the central position of two triangle star-shaped shelf 2 that are disposed relatively rotatably respectively, the sun gear 5 engages with planetary gear and location support planetary gear 4 of the planetary gear shaft 7, fix the inner gear 3 on the planetary gear outside of the said location support planetary gear 4 and two planetary gear shafts 7 and fit the mounting inner gear ring 3 that engages each other, fix ripple disc coulter 6 on the inner gear ring 3, the soil crushing knife roller 8 and the seed furrow extrusion molding roller 9 are respectively supported and fixedly arranged on the planetary gear shafts 7 which are oppositely arranged at the front side part of the lower end of the triangular star-shaped frame 2 and the planetary gear shafts 7 which are oppositely arranged at the rear side part of the lower end of the triangular star-shaped frame 2.

During operation, the whole operation monomer is assembled on a soil preparation operation or sowing operation machine through the monomer frame 1, and the random tool moves forward. When the corrugated disc coulter 6 is cut into soil, the corrugated disc coulter 6 rotates along with the soil resistance, when the soil on the seedbed strip is disturbed, loosened and crushed by extrusion, the rotating power of the corrugated disc coulter 6 sequentially drives the soil crushing cutter roller 8 and the seed furrow extrusion forming roller 9 to rotate through the inner gear ring 3 and the planetary gear shafts 7 on the front and rear side parts of the lower end of the triangular star-shaped frame 2 respectively, the soil on the seedbed strip is ground by the rotating ground crushing cutter roller 8 in a rotary tillage mode again, then the rotating ground seed furrow extrusion forming roller 9 extrudes a seed furrow with regular and standard furrow shape, proper soil layer density, standard size and good quality on the strip soil, and meanwhile, the cylindrical parts on the two sides of the seed furrow extrusion forming roller 9 extrude and level the strip seedbed soil on the two sides of the upper end of the seed furrow, thereby providing a high-quality seed bed for seeding operation.
