Problems solved by technology

Therefore, there is always a left or right reseeding disk that is ineffectively rotating, but it still needs to consume the kinetic energy of the motor to drive the rotation of the left or right reseeding disk. Invisibly, a higher power motor needs to be selected, which increases the cost.

Embodiment 1

[0105] In this corn missed sowing re-seeding device, the main shaft two 26 is provided with a shoulder 26-1, and the left re-seeding disc 21 and the right re-seeding disc 22 centers are rotationally connected with the main shaft two 26, and the left re-seeding disc 21 and the right re-seeding disc 22 are rotationally connected. The right replanting disc 22 is separated by shoulder 26-1, avoiding the contact of the left reseeding disc 21 and the right reseeding disc 22 side walls, only the left reseeding disc 21 rotates replanting for the main shaft two 26 counterclockwise rotations, and the right reseeding disc 21 rotates replanting. The reseeding disk 22 does not rotate; the main shaft two 26 rotates clockwise and only the right reseeding disk 22 rotates replanting, and the left reseeding disk 21 does not rotate, providing a structural basis.

[0106] The left side of the left reseeding disc 21 is provided with a left ratchet drive assembly, and the left ratchet drive assembly...

Embodiment 2

[0113] On the basis of Embodiment 1, the number of holes 2 2-2 on the left swivel seat 21-2 is an odd number, and only one side of the left swivel seat 21-2 is provided with a left groove 21-20; The type hole 2 2-2 on the swivel base 22-2 is an odd number, and the right swivel base 22-2 is only provided with a right groove 22-20 on one side; then the left swivel base 21-2 and the right swivel base 22- 2 The lower end is provided with a balance block 21-21, which ensures the stability of the dynamic balance of the left swivel base 21-2 and the right swivel base 22-2 along with the rotation of the main shaft two 26, and reduces mechanical vibration.

[0114] The number of holes 2-2 on the left swivel base 21-2 is an even number, and left grooves 21-20 are arranged on both sides of the left swivel base 21-2; the type holes on the right swivel base 22-2 Two 2-2 are an even number, right grooves 22-20 are provided on both sides of the right swivel base 22-2, and there is no need to...

Embodiment 3

[0116] 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.

[0117] 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 device for missed sowing and reseeding of corn and a control method thereof, including a seed metering device. Outer card 1, rolling bearing 1, bearing end cover 1 and bearing end cover 2, the 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 cavity cover It is firmly connected with one side of the seat shell, the seed protection plate is connected with the inner wall of the seat shell in a circumferential sliding manner, one end of the main shaft is rotationally connected with the center of the first seed filling cavity cover through a rolling bearing, and the other end of the main shaft is connected with the The rotating connection at the center of the shell also includes a re-seeding device, which effectively reduces the missed seeding rate of the corn precision seeder, improves the seeding quality and production efficiency; realizes that the main shaft 2 rotates counterclockwise, only the left re-seeding disc rotates for re-seeding, and the right re-seeding disc rotates for re-seeding. The seed disk does not rotate, and does not consume the kinetic energy of the motor; the power requirement of the motor is reduced, and the equipment cost is saved.

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...
