Seeder with seedling strip cleaner

Abstract

The invention provides a seeder with a seedling strip cleaner. The seeder comprises a frame, furrow openers as well as a seedling box, a fertilizer box, seed-metering devices, fertilizer apparatuses, plow poles, ground wheels and roller sealers which are arranged on the frame, wherein the plow poles are all hollow; each furrow opener is fixed at the bottom of the frame by the plow pole; the plow poles extend into the lower ends in the furrow openers so as to serve as fertilizer discharge outlets; the upper ends of the plow poles are communicated with the fertilizer box by the fertilizer apparatuses; and the seed-metering devices which are communicated with the seed box are positioned above the rear ends of the furrow openers. The seeder is characterized in that: the bottom surfaces of thefurrow openers are raised in a ladder shape from front to back along the travelling direction; both sides, which are positioned between the fertilizer discharge outlets and the seed-metering devices,of the furrow openers are provided with scrapers; the seedling strip cleaner is arranged at the front ends of the furrow openers; the seeder comprises two axle bases which are suspended on the frame,a rotary knife shaft of which a horizontal bearing is arranged between the two axle bases, a power transmission mechanism and pairs of rotary knives which are arranged on the rotary knife shaft; eachpair of rotary knives are symmetrically arranged at an angle of 180 degrees; and one furrow opener is arranged right behind each pair of rotary knives. The seeder has a simple structure and excellentworking performance.

Description

technical field [0001] The invention provides a planter with a seedling belt cleaner, which belongs to the technical field of agricultural sowing. Background technique [0002] At present, corn is sown immediately after wheat harvesting. After the wheat combine harvester operates, wheat straw, stubble, and weeds are all on the surface. Therefore, farmers usually burn the straw or clear the field; if the field is hard or the furrow plow works on the wheat stubble, the furrow plow has poor penetration into the soil, and the The depth of the ditch is shallow, which cannot meet the requirements of sowing. This is an important factor affecting the quality of sowing. In the 2009 National "Special Funding Project for Public Welfare Industry (Agriculture) Research", the planter prevents straw and weed congestion as one of the main technical difficulties. one.

Problems solved by technology

[0002] At present, corn is sown immediately after wheat harvesting. After the wheat combine harvester operates, wheat straw, stubble, and weeds are all on the surface. Therefore, farmers generally burn the straw or clear the field; if the field is hard or the furrow plow works on the wheat stubble, the furrow plow has poor penetration into the soil, and the The depth of the ditch is shallow, which cannot meet the requirements of sowing. This is an important factor affecting the quality of sowing. In the 2009 National "Special Funding Project for Public Welfare Industry (Agriculture) Scientific Research", the planter prevents straw and weed congestion as one of the main technical difficulties. one

[0003] There are two basic forms of the grass-free device. One is the grass-free device applied on the straw returning machine, such as the grass-free rotary tiller with application numbers 200620166370, 200810099696, and 200620126182. All the inland surfaces are rotary tilled, which consumes a lot of power and has a complex structure; another example is the passive anti-entanglement roller device of the ditching type seeder with the patent No. 02287131.4. On the one hand, when the amount of straw is large or the soil humidity is high, the rotary roller cannot rotate and cannot play the role of preventing grass from entanglement and congestion

In addition, currently used seeders, the fertilization furrow plow and the seeding furrow plow are two independent plow bodies, which directly furrow and sow and fertilize on the sowing stubble. The front and rear dimensions of the seeder are long, the structure is complex, and the power consumption is large.
