Problems solved by technology

[0003] Spoon chain seed metering device is a kind of seeding device commonly used in small and medium-sized potato planters at present, but in actual work, due to the characteristics of irregular shape and poor fluidity of potato seed potatoes, it makes it difficult to take seeds and the phenomenon of missing seeding affects the quality of the seeds. Sowing efficiency and quality
At present, the main solutions are divided into manual reseeding and optimizing the structure and operating parameters of the metering device, but manual reseeding will increase the working time and work cost, and manual reseeding will also be difficult to accurately detect because the seeder moves faster Missed sowing position, artificial inability to replant in time will lead to missed sowing phenomenon; optimizing the structure and operating parameters of the seed metering device will still have a 7% missed sowing rate

Embodiment Construction

[0024] See figure 1 One of the embodiments of the present invention proposes a potato seeding machine leakage detection and supplementary system, including: bracket 1, breeding board 3, spoon 11, leakage detection device 6, control system 10, and species device.4.

[0025] See figure 2 The leak detection device includes Hall sensor 8. Man-reflective photoelectric switch sensor 7; this implementation is selected for HM18-50NA Hall sensor, BF-M12JG-DS15C1-type man-phenomenon switch sensor.

[0026] See further figure 2 , 2 are 2 sensors 7, including the drill photovoltaic switch sensor 7A and the man -reflective photoelectric switch sensor 7B, which are installed on both sides of the seed plate 3, respectively reflecting photoelectric switch sensor 7A than the Mano -Power switch sensor 7B 7B20mm low; Hall sensor 8 is installed at 136.3mm above the beam of light electric switch sensor 7A; the spoon 11 is close to the Hall sensor 8 on the side with a circular permanent magnet 9, the H...

Abstract

The invention provides a miss-seeding detection and reseeding system of a potato seeder. The miss-seeding detection and reseeding system comprises a bracket, a seed protection plate, a seed spoon, a miss-seeding detection device, a control system, a reseeding device and the like. The miss-seeding detection and automatic reseeding mode is adopted, so that the operation cost and the labor intensity can be effectively reduced, the miss-seeding rate can be effectively reduced, and the purposes of low cost and high efficiency are achieved. A'dislocation positioning method 'is adopted, so that the influence of induction time difference generated between a Hall sensor and a diffuse reflection laser correlation sensor on the detection precision is avoided, and meanwhile, the phenomenon that reseeding is not timely due to the fact that the seeding speed is increased is also avoided.

Description

Technical field [0001] The present invention involves the field of potato seedling technology, and is specifically for a potato seeding machine leakage detection and supplementary system. Background technique [0002] As a large agricultural country, potato production has ranked first in the world for many years, but due to the low level of potato planting equipment, artificial planting methods are currently mainly used, which seriously hinders the development of the potato industry.Potato sowing machine is an important machine for the development of the potato industry. The quality of sowing is closely related to the growth and development of potato and the output, while the seeding device has a very important role in the quality of sowing. [0003] The spoon chain rower is currently a kind of sowing device generally adopted by small and medium -sized potato seeders.Sowing efficiency and quality.At present, the main solutions are divided into the structure and operating paramete...
