Seeding and fertilizer apparatus of non-ploughing sowing machine

Abstract

The invention relates to a seeding and fertilizing machine of a no-tillage seeder. A shell is provided with a seeding shaft which passes through the shell, and the upper part of the shell is provided with a seeding chamber and a fertilizing chamber which are isolated; the lower part of the shell corresponding to the seeding chamber and the fertilizing chamber is provided with a seeding opening and a fertilizing opening; a seed scraping plate and a seed scraping brush are arranged on a side wall of the shell at the seed feeding side of the seeding chamber; the seeding shaft is coaxially provided with a first seeding wheel and a second seeding wheel with holes of two different types as well as a fertilizing wheel; the inside of the fertilizing wheel is connected with the seeding shaft by aninternal elastic pin, and a fertilizing grooved pulley is arranged on the inside of the fertilizing wheel; a groove stop plate is arranged on an end of the second seeding wheel on the shell; a convexbaffle arranged at an inner hole of the groove stop plate is arranged in the fertilizing grooved pulley; a block wheel is arranged on an axial diameter of the outside of the fertilizing wheel; a sliding brush against the external end face of the block wheel is connected with the seeding shaft by an external shaft pin; and the shell is provided with plug boards corresponding to the four types of holes. The seeding and fertilizing machine has the characteristics of compact structure, good versatility and flexible seed and fertilizer amount adjustment according to different seeding speeds.

Description

technical field [0001] The invention relates to a seed and fertilizer discharger for a no-tillage seeder, belonging to the technical field of seeders. Background technique [0002] During the tillage process, the no-tillage seeder first cuts the straw on the ground through the cutter and ditches the ground, and then continues to dig the ditch along the ditch through the ditch opener to expand it into a sowing area. When ditching, fertilizer and seed are discharged through the seed and fertilizer discharger at the same time, and the ditch, fertilizer, seed and soil covering are completed at one time. [0003] The seed and fertilizer discharge mechanism of the no-tillage seeder is composed of an outer groove wheel type seed meter and a star wheel type fertilizer discharger. The outer groove wheel type seed metering device is mainly composed of a seed metering box, a seed metering shaft, an outer groove wheel, a blocking sleeve and a seed metering tongue. The sheave rotates w...

AI Technical Summary

Problems solved by technology

Since the power of the seed metering device and the fertilizer discharger comes from the profiling ground wheel, the profiling ground wheel connects the power to the seeding shaft through the secondary chain transmission, drives the outer groove wheel to rotate the seeding, and the seeding shaft passes through a pair of positive The gear is connected with the fertilizer discharge shaft, and the fertilizer discharge shaft is connected with the fertilizer discharge star wheel after passing through the large and small bevel gears. In operation, six different transmission ratios can be obtained by switching the three sprockets on the secondary sprocket to adjust the amount of seeds. The fertilizer discharge rate is based on the transmission ratio, and the transmission ratio of a pair of spur gears on the fertilizer discharge shaft is replaced to meet the adjustment requirements. The operation of adjusting the seed and fertilizer discharge volume is cumbersome, and it is not easy to accurately adjust the seed volume and fertilizer. volume ratio
