Problems solved by technology

Most of the seedling delivery mechanisms of the existing pot seedling transplanting machines are ratchet-connecting rod combination mechanisms. The transmission of the mechanism is not stable, the transmission ratio is not accurate, the work reliability is poor, the service life is short, and the vibration and noise during operation are large, which is easy to cause seedlings. knocked out of the bowl
Since the seedling feeding angle is fixed each time when pot seedlings are transplanted, and the distance between each pot body is fixed, it is required to have an accurate longitudinal seedling feeding distance, that is, an accurate transmission ratio, so that there will be no error accumulation, otherwise the seedling tray will be damaged, and the transplanting decline in quality

Abstract

The invention relates to a gear-driven pot seedling transplantation longitudinal seedling feeding mechanism, and belongs to agricultural machinery. According to the gear-driven pot seedling transplantation longitudinal seedling feeding mechanism, a seedling feeding shaft drive gear is fixed on a seedling feeding shaft and positioned on the outer side of a seedling box side support, a rotation arm shaft welding is matchedly arranged on the seedling box side support and positioned below the side of the seedling feeding shaft, an inner ratchet and outer gear assembly is arranged on the rotation arm shaft welding, a pawl and a spring sheet are fixed on the rotation arm shaft welding, the pawl and the inner ratchet teeth of the inner ratchet and outer gear assembly form snapping contact matching, the spring sheet bears against on the pawl, the outer gear of the inner ratchet and outer gear assembly is engaged with the seedling feeding shaft drive gear, the transmission ratio is 1:2, and a push-pull rod and the rotation arm shaft welding form a hinge connection. The gear-driven pot seedling transplantation longitudinal seedling feeding mechanism has characteristics of novel, reasonable and compact structure design, accurate and stable transmission, low vibration, low noise, less failure, and no damage on the seedling tray.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a longitudinal seedling delivery mechanism for pot seedling transplanting on a planting machine tool. Background technique [0002] Pot seedling transplanting has become the most direct mechanized planting method to increase grain production, and the corresponding supporting machinery is also gradually developing. The vertical seedling feeding mechanism for pot seedlings has become an important part of the seedling box. Most of the seedling delivery mechanisms of the existing pot seedling transplanting machines are ratchet-connecting rod combination mechanisms. The transmission of the mechanism is not stable, the transmission ratio is not accurate, the work reliability is poor, the service life is short, and the vibration and noise during operation are large, which is easy to cause seedlings. Shake it from the bowl. Since the seedling feeding angle is fixed each time when pot seedl...
