Description
Technical field
The utility model belongs to the technical field of agricultural tool, is specifically related to the two strain precision sowers in a kind of corn one cave.
Background technology
Corn is the second largest cereal crops of China, occupies extremely important status in grain-production, plays a part very important in national economy.China's corn yield fluctuates in recent years, in urgent need to be improved, and the main path that improves corn yield increases the density of milpa, but only increasing plant spacing can cause corn stem to attenuate, and has the easily danger of lodging, after lodging occurs output do not increase anti-will.
Research shows, corn is carried out the two strains in a cave, and both can improve output can also be resistant to lodging.The two strains in one cave refer to the two strain corns of planting in a hole, due to two strain maize seeds together, the root system of two strain corns intersects mutually, to root growth reinforcement effect, has strengthened lodging tolerance.In traditional cave one plant planting method, the density of milpa is 3000-3500 plant/acre, corn per mu yield is generally 400-500kg, and the implantation methods of the two strains in a cave suitably increases the quantity of every mu of plant by adjusting the line-spacing of milpa, realize the reasonable disposition in field, the density of milpa can reach 5000-6000 plant/acre, and per mu yield can reach 500-800kg.Therefore, the implantation methods of the two strains in corn one cave has volume increase and feature resistant to lodging.
The quality of sower service behaviour will directly have influence on the quality of seeding operation productivity ratio and emergence of corn, and seeding unit is the core component of corn drill, is the principal element that determines sower characteristic and service behaviour.Existing corn drill seeding unit mainly contains: external feed, turn spoonful formula seeding unit and air-sucking type single-kernel seed-metering device.
Outer groove-wheel rotation during external recessing work, seed is full of sheave groove by gravity, and with rotation together, forced seeding by outer groove-wheel, its seeding quantity depends on effective active length and the rotating speed of sheave, in seeding process, be subject to the impact of machine vibration, amount of seed metering has pulsation phenomenon, Seeding Uniformity is poor, and can not realize the precision drilling of the two strains in a cave.
Turning a spoonful formula seeding unit is to utilize type hole size to get kind, realizes simple grain bunch planting and program request, and its structure and its regulative mode easily cause seed number per unstable, each cylinder population size of sowing is inconsistent, when seeding unit drum rotation speed is lower, fills kind of the time long, without hole, but clear kind has some setbacks, and seed number per is unstable, when drum rotation speed is higher, it is short to fill kind of the time. and seed easily stops up at seed inlet, easily form hole, operation easier is large, can not realize the precision drilling of the two strains in a cave.
In recent years, development along with defective ejaculation amount seeding technique, developed again a kind of pneumatic type vertical circular disc type precision quantitative seed drill (air-sucking type single-kernel seed-metering device), one one, cave, its sowing simple grain rate reaches more than 92%, very strict to the requirement of percentage of seedgermination, common seed does not reach sowing requirement, can not realize the sowing in two, a cave.
