Ultra-narrow row rotary tillage and fertilization integrated type wheat high-yield seeding machine

Abstract

The invention belongs to the technical field of agricultural farming machinery, and provides a narrow row wheat seeding machine which is capable of tilling rotatably, fertilizing and seeding. The ultra-narrow row rotary tillage and fertilization integrated type wheat high-yield seeding machine is high in yield, efficient and low in operation cost. According to the technical scheme, the ultra-narrow row rotary tillage and fertilization integrated type wheat high-yield seeding machine comprises a rack, a suspension bracket, a rotary tillage mechanism, an arrow type fertilizing and seeding ditching mechanism, a dual-disc fertilizing and seeding ditching mechanism, a pressing mechanism and fertilizer and seed discharging boxes. The suspension bracket is fixedly mounted on the upper portion of the front end of the rack, the rotary tillage mechanism is mounted on the lower portion of the front end of the rack, the arrow type fertilizing and seeding ditching mechanism and the dual-disc fertilizing and seeding ditching mechanism are mounted on the lower portion of the middle of the rack from front to back in sequence, the upper end of the arrow type fertilizing and seeding ditching mechanism and the upper end of the dual-disc fertilizing and seeding ditching mechanism are respectively provided with one fertilizer and seed discharging box, the two fertilizer and seed discharging boxes are fixed on the rack, the pressing mechanism is mounted on the lower portion of the back end of the rack, and the fertilizer and seed discharging devices of the two fertilizer and seed discharging boxes are connected with the pressing mechanism through a fertilizer and seed discharging transmission mechanism. The ultra-narrow row rotary tillage and fertilization integrated type wheat high-yield seeding machine is mainly used for seeding wheat.

Description

technical field [0001] The invention discloses an ultra-narrow row rotary tillage and fertilization integrated wheat high-yield seeder, belongs to the technical field of agricultural farming machinery, and in particular relates to a wheat seeder. Background technique [0002] Agricultural conservation tillage technology is the most advanced sustainable development agricultural technology in the world today, and it is an agricultural cost-saving and efficiency-enhancing environmental protection technology that is mainly popularized and applied nationwide. Its main technical features: surface crop straw coverage, less tillage or no-tillage of the soil, and the surface straw residue coverage rate after crop sowing is required to be greater than 30%. The widely used wheat conservation tillage and seeding technology, in the dryland wheat area with one crop a year, firstly carry out rotary tillage under the condition of wheat stubble and straw covering the surface, and then carry ...

AI Technical Summary

Problems solved by technology

The main problems: ①Rotary tillage for land preparation or rotary tillage for seeding, deep rotary tillage, serious soil suspension, high soil water loss, poor water storage and moisture conservation capacity, poor resistance to freezing damage and drought resistance of wheat, and low wheat yield ; After sowing, the surface straw coverage rate is low, the soil is seriously exposed, and wind erosion, water erosion, soil erosion, and air pollution by sand and dust are prone to occur, which destroys agricultural ecological resources. It is an outdated production technology recommended by agricultural experts; ②The current wheat The sowing row spacing is 20 cm, and the wheat plants in the wheat sowing row are too concentrated, which is not conducive to the development of individual wheat plants, and is not conducive to the full utilization of soil water and fertilizer resources. Many, high production cost, high energy consumption, not conducive to low-carbon agricultural production

In 2011, Hongdong County, Linfen City's water-land wheat dispersal (artificial random seeding) technology created a historical record of 707 kg of wheat per unit area. At present, it can only be operated manually, and the amount of seeds used is relatively large, and the production cost is relatively high; according to related reports, Beijing, Hebei, Shandong, Xinjiang and other places have tested and studied wheat mechanical spreaders and narrow row wheat (sowing row spacing 14-16 cm) The seeder, but it cannot be used for sowing on the ground covered with straw, it only solves the problem of close planting of wheat, but does not solve the problem of the passability of sowing wheat under the condition of covering the ground with straw
