Embodiment 1

[0080] In the corn missed seed replenishing device, the lower end of the housing 10 of the seed metering device 1 is provided with a seed storage hopper 100, and the side of the seed storage hopper 100 is provided with an optical fiber sensor 101, so as to realize the seeding of the seed meter 1 Real-time monitoring provides real-time signals for missed seeding for the single-chip microcomputer; the lower end of the seed storage hopper 100 is connected with a blanking pipe 102 to ensure that the seeds fall accurately in the trench opened by the trencher and prevent the seeds from falling on the base soil on both sides , Causing seeding failure.

[0081] The second seed hopper 200 is provided at the lower end of the second seat shell 20, and the second seed hopper 200 is provided with a partition 201 in the middle. The second seed hopper 200 is divided into a left chamber 201-1 and a right chamber 201-2. A left rotating cylinder 202 is provided on the outer wall of the left chambe...

Embodiment 2

[0084] The control system of the corn missed seed replenishing device 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 and an optical fiber sensor at the lower end of the seed metering device 1 on the right 101 are respectively connected to the input end of the single-chip microcomputer. The first solenoid valve and the second solenoid valve are connected to the output end of the single-chip computer. 206 is connected by the trachea.

[0085] 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, and then the seed metering devices 1 on both sides work, and the spindle 14 passes outside The spline and spline hole 1-1 drive the seed metering disk 11 to rotate, and the seeds in the first seed filling chamber cover 12 enter the U-shaped curve...

Abstract

The invention discloses a corn miss-seeding reseeding device and a control system. The corn miss-seeding reseeding device comprises seed metering devices, wherein each seed metering device consists ofa first seat shell, a seed metering plate, a first seed filling cavity cover, a first seed protection plate, a first main shaft, a first outer clamp, a first rolling bearing, a first bearing end cover and a second bearing end cover; each first seat shell is mounted below a seeder; each first main shaft is connected with the center of the corresponding seed metering plate through an outer spline;each seed metering plate is axially limited by the corresponding first outer clamp; each first seed filling cavity cover is in fastening connection with one side of the corresponding first seat shell;each first seed protection plate is in circumferential sliding connection with an inner wall of the corresponding first seat shell; one end of each first main shaft is in rotary connection with the center of the corresponding first seed filling cavity cover through the corresponding first rolling bearing; the other end of each first main shaft is in rotary connection with the center of a housingthrough the corresponding first rolling bearing; the corn miss-seeding reseeding device further comprises a reseeding device; one reseeding device is directly arranged on the adjacent seed metering devices; one reseeding device is used for carrying out reseeding operation on two rows of seed metering devices; the corn miss-seeding reseeding device is simple and compact in structure and high in reseeding accuracy and instantaneity; and the miss-seeding rate of a corn precision seeder is reduced, and the seeding quality and the production efficiency are improved.

Description

Technical field [0001] The invention belongs to the technical field of planters. Specifically, the invention relates to a corn missed seeding replenisher and a control system. Background technique [0002] Precision seeding of corn is an important technology to increase corn yield and save costs. In the process of corn planting, the performance of precision seeders is an important factor that affects the emergence and yield of corn, and the metering device affects precision seeding. The key component of machine performance. [0003] At present, most corn precision seeders used in China use mechanical precision metering devices. Due to the influence of mechanical structure, field working environment and other factors, there will inevitably be missed seeding during the seeding process, for example: single-sided For the full-seed metering device, when the operation equipment is tilted to one side during uneven field operations, it is easy to cause missed seeding; in order to improve ...
