Abstract

The invention provides a seedling-cultivation flexible seeding apparatus, relating to the field of agricultural machinery technology; the seedling-cultivation flexible seeding apparatus comprises a seedling storage plate and a seedling dropping plate, the seedling storage plate is arranged on the seedling dropping plate and can move relative to the seedling dropping plate, the seedling storage plate and the seedling dropping plate are provided with a seedling filling hole and a seedling dropping hole correspondingly, under a seedling filling state, the seedling filling hole and the seedling dropping hole are staggered, and under a sowing state, the seedling filling hole and the seedling dropping hole are run-through; the seedling-cultivation flexible seeding apparatus is characterized in that: two seedling filling hairbrushes are arranged on a parallel bracket above the seedling storage plate, two seedling filling hairbrushes rotate inwards by respectively revolving the seedling filling hairbrush shafts and are respectively tangent with the seedling storage plate, and a seedling containing space is left between the two seedling filling hairbrushes; the seedling storage plate and the seedling dropping plate are arranged on a transmission mechanism and do reciprocating motion vertical to the direction of the seedling filling hairbrush shafts, and a spring resetting device is arranged between the seedling storage plate and the seedling dropping plate. The seedling-cultivation flexible seeding apparatus is suitable for characteristics of different crop seedlings, meets the seedling-cultivation agricultural requirements, increases the using efficiency of an automatic system in the existing assembly line and has the advantages of flexible seedling filling and no damage to the seedlings.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a precision sowing device on an automatic seedling raising and sowing line. Background technique

[0002] The existing seedling raising and sowing assembly lines are divided into two categories, one is the air suction seedling raising and sowing assembly line, and the other is the outer groove wheel type seedling raising and sowing assembly line. At present, due to its relatively simple structure and moderate price, the seedling raising and sowing line adopting outer groove wheel sowing has been widely popularized in rural areas and large farms in my country, and has been widely welcomed by users. However, the external grooved wheel sowing method has a better effect for rice seedling raising, but it cannot adapt to the agronomic requirements for seedling raising of all crops. For example: flowers, tobacco, vegetables and other crop seeds with small particles and l...
