Orientation positioning seeder

Abstract

The invention discloses an orientation positioning seeder. The orientation positioning seeder comprises a workbench, a conveying device, an aperture disk, an aperture pressing mechanism, an oriented seed aperture device, a negative pressure seed discharge device, a sprinkling device, a guide rod, a position sensor and a control case. The workbench comprises a frame and a workbench surface. The conveying device is installed on the workbench surface and is used for conveying the aperture disk according to a flow line working process so that the aperture disk goes through the aperture pressing mechanism, the oriented seed aperture device, the negative pressure seed discharge device and the sprinkling device, PLC is used for controlling the whole seeder, the oriented seed aperture device adopting a machine vision technology realizes seed direction adjustment, the negative pressure seed discharge device carries out orientation positioning sowing on the seeds subjected to direction adjustment, the sprinkling device is used for watering the apertures with the seeds, and the position sensor is used for accurately detecting and feeding back the work process. The orientation positioning seeder realizes 45 degree orientation positioning sowing of large seeds. The orientation positioning seeder solves the problem that the manual sowing method has low work efficiency and causes fatigue easily, can cultivate standard seedlings and provides favorable conditions for automatic grafting implementation.

Description

technical field [0001] The invention relates to a directional positioning seeder, in particular to a directional positioning sowing device capable of keeping the long axis of large seeds in a 45° direction, with the seed germination opening facing the same direction and located at the center of the hole, belonging to the technical field of precision agricultural machinery. Background technique [0002] The precision seeding machine for plug seedlings is the key equipment for industrial seedling raising technology. The research on the precision seeding machine for plugs at home and abroad is earlier, and precision seeding for regular-shaped or pelletized seeds has been realized. However, the size and quality of large seeds such as pumpkins and gourds are large, and they are not spherical. Generally, precision seeders cannot sow them precisely; Usually, artificial 45° orientation is used to plant seeds, which is low in efficiency and prone to fatigue; most of the current graft...

Problems solved by technology

[0004] The purpose of the present invention is to provide a directional positioning seeder, specifically to sow seeds that are relatively large in volume and quality, such as pumpkins and gourds, and are flattened into ovals, so as to solve the problem of different orientations of the seed germination ports after sowing large seeds. The position of the germination mouth is also distributed differently relative to the center of the hole, and it provides a method for cultivating cotyledons with the same orientation and reducing mutual shading.
