Problems solved by technology

[0003] At present, most of the corn precision seeders used in China use mechanical precision seeders. Due to the influence of factors such as mechanical structure and field operation environment, it is inevitable that there will be missed seeding during the sowing process. Seed metering device for filling seeds, when working in uneven fields, the operating equipment is tilted to one side and it is easy to cause missing seeding; in order to improve the operation effect of the seeder and increase the yield of corn, it is necessary to detect the phenomenon of missing seeding and reseeding in real time one question

Embodiment 1

[0083]In this corn leakage reseeding device, the lower end of the seat shell-10 of the seed metering device 1 is provided with a seed storage bucket-100, and the side of the seed storage bucket-100 is provided with an optical fiber sensor 101, so as to realize the control of seeding of the seed metering device 1. Real-time monitoring, providing real-time signal for the single-chip microcomputer; the lower end of the seed storage bucket 100 is connected with a feeding pipe 102, which ensures that the seeds fall accurately in the ditch opened by the ditching machine, and prevents the seeds from falling into the base soil on both sides , resulting in seeding failure.

[0084] The lower end of the seat shell two 20 is provided with a seed storage bucket two 200, and a partition plate 201 is arranged in the middle of the two seed storage bucket 200, and the second storage bucket 200 is divided into a left chamber 201-1 and a right chamber 201-2, so that A left rotary cylinder 202 i...

Embodiment 2

[0087] The control method of the corn leakage reseeding device, the control system includes a single-chip microcomputer, a solenoid valve 1 and a solenoid valve 2, an optical fiber sensor 101 at the lower end of the seed metering device 1 on the left side and an optical fiber sensor at the lower end of the seed metering device 1 on the right side 101 is respectively connected with the input end signal of the single-chip microcomputer, and the first electromagnetic valve and the second electromagnetic valve are connected with the output end signal of the single-chip microcomputer. 206 is connected by a trachea.

[0088] First put the corn seeds into the first seed-filling chamber cover 12 on both sides and the left seed-filling chamber cover 23 and right seed-filling chamber cover 24 in the middle, then the seed meters 1 on both sides work, and the main shaft one 14 passes through the outer The cooperation between the spline and the spline hole 1-1 drives the seeding disk 11 to...

Abstract

The invention discloses a corn missed sowing reseeding device and a control method thereof, comprising a seed metering device, the seed metering device is composed of a seat shell 1, a seed metering tray, a first seed filling chamber cover, a seed protection plate 1, a main shaft 1, and an outer card 1. Rolling bearing 1, bearing end cover 1 and bearing end cover 2. Seat shell 1 is installed under the seeder. Main shaft 1 is connected to the center of the seeding disc through an external spline, and the axial direction of the seeding disc is limited by the outer card 1. , the first seed-filling chamber cover is fastened to one side of the seat shell, the seed protection plate is connected to the inner wall of the seat shell by sliding in the circumferential direction, the main shaft-one end is rotationally connected to the center of the first seed-filling chamber cover through a rolling bearing, and the main shaft The other end is rotationally connected to the center of the housing through a rolling bearing, and also includes a re-seeding device, and a re-seeding device is directly provided on the adjacent seed metering device, and a re-seeding device is used to re-seed two rows of seed metering devices. The structure is simple and compact, and the replanting accuracy and real-time performance are high, which reduces the missed seeding rate of the corn precision seeder, and improves the seeding quality and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of seeding machines, in particular, the invention relates to a device for missed sowing and reseeding of corn and a control method. Background technique [0002] Corn precision seeding is an important technology to increase corn yield and save costs. In the process of corn planting, the performance of the precision seeder is an important factor affecting the emergence of corn seedlings and the yield. The seed meter is also an important factor affecting precision seeding key components of machine performance. [0003] At present, most of the corn precision seeders used in China use mechanical precision seeders. Due to the influence of factors such as mechanical structure and field operation environment, it is inevitable that there will be missed seeding during the sowing process. Seed metering device for filling seeds, when working in uneven fields, the operating equipment is tilted to one side and it is eas...
