Abstract

The invention relates to a large-seed directional seeding device, comprising an operating platform, a conveying mechanism, a seedling disc, a hole pressing mechanism, a camera shooting detection mechanism, a seeding mechanism, a seed box, a guide plate, a direction adjusting mechanism, a correcting mechanism and a control box, wherein the operating platform comprises a rack and an operating platform surface; the conveying mechanism, the hole pressing mechanism, the camera shooting detection mechanism, a seed absorbing mechanism, the direction adjusting mechanism and the correcting mechanism are connected with a control system in the control box; and the camera shooting detection mechanism is a computer which is externally connected with the control system in the control box and is internally equipped with image processing software. According to the large-seed directional seeding device provided by the invention, a sensor accurately detects and feeds back a working process, a conveying speed is controlled by virtue of frequency modulation of a stepping motor, bidirectional throttle valves and one-way throttle valves are adopted for regulating speed during the reciprocating motion of a hole pressing cylinder and a correcting cylinder and a gas collecting tube connecting suction needle motion, and directional planting with consistent germination point orientation after planting is realized.

Description

technical field [0001] The invention relates to a directional seeding machine, in particular to a large seed directional sowing device for providing standardized seedlings for an automatic grafting machine, and belongs to the technical field of precision agricultural machinery. Background technique [0002] Because grafting can overcome the continuous cropping obstacles of crops and increase crop yield, grafting technology has been widely used in protected cultivation in recent years, and has broad technical application prospects. In order to improve the efficiency of vegetable grafting and reduce the labor intensity of workers, domestic and foreign researches on the automation of grafting are constantly being carried out. Although the grafting process has been automated, for some grafting methods, such as the sticking method, the grafting machine has certain direction requirements for the direction of the cotyledons of the seedlings during grafting. At present, most graftin...
