Driving control signal collecting device for groove wheel of seeding machine or fertilization seeding machine

Abstract

The present invention relates to an improved device of a seeding machine or a fertilization seeding machine in agricultural machines, and discloses a driving control signal collecting device for a seed or fertilizer discharge groove wheel of the seeding machine or the fertilization seeding machine, roller wheels are arranged on the seeding machine or the fertilization seeding machine, the roller wheels are contacted with the ground, the roller wheels rotate along with the forward moving of the seeding machine or the fertilization seeding machine, and electrical signals which are outputted while the roller wheels rotate are transmitted to a driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. A rotating shaft (8) of the roller wheels collects the electrical signals by a rotation speed sensor to transmit to the driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. The rotating shaft (8) of the roller wheels is provided with a grating disc (4), an infrared probe (10) on the side of the grating disc (4) collects the electrical signals to transmit to the driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. The driving control signal collecting device has the advantage of simple structure, the whole driving control signal collecting device combines two technical characteristics, the driving control signal collecting device can sensitively and accurately reflect and collect actual operation conditions of the seeding machine or the fertilization seeding machine, also can conveniently and quickly transfer the actual operation conditions to the driving control device of the groove wheel of the seeding machine or the fertilization seeding machine to obtain accurate signals so as to achieve the purpose of the driving control signal collecting device.

Description

technical field [0001] The invention relates to an improved mechanism of a seeder or a fertilizer applicator or a fertilizing seeder in agricultural machinery, in particular to an improved device for collecting the driving control signal of the sheave of such machinery. Background technique [0002] The invention is mainly used for the driving control of the seeding or fertilizer sheave of the seeder or fertilizing seeder, so that the rotation and rotation speed of the seeding or fertilizing sheave of the seeder or fertilizing seeder are synchronized with the planter unit, so that the Uniform and precise sowing or fertilization, to meet the requirements of no missed sowing and no re-seeding, this is a key device that must be equipped with a seeding or fertilizing machine, and it is also one of the technical guarantees to ensure increased grain production and high yield. At present, 700,000 to 800,000 sets of various types of seeders or fertilization seeders are produced in C...

AI Technical Summary

Problems solved by technology

This technology is a traditional technology. Its advantages are good machine integrity, simple operation and pure mechanical transmission. It has three main disadvantages: first, the transmission resistance of the ground roller is large, unreliable, difficult to adjust, and high in cost; second, it is mechanically driven. There is a certain resistance to the rotation of the wheel shaft of the seeding or fertilizing tank. Due to the softness of the soil and the difference in the flatness of the ground during sowing or fertilization, it is easy to cause the ground roller to "slip" and not rotate or rotate slowly. Or sowing is uneven; third, due to the use of ground rollers and chain drives, the size of the mechanism is large, the manufacturing cost is high, and the transmission speed ratio cannot be adjusted, which is not conducive to the realization of variable control and automatic control, and is not conducive to the realization of intelligent equipment

These shortcomings have always restricted the technical development and progress of seeders or fertilizing seeders

But there are four main disadvantages: one is the disadvantage of the second control method; the other is that because the tractors are different, the installation positions on the outside of the drive wheel are also different, so it is necessary to reserve multiple connecting discs, which has poor versatility, and the structure is complex and difficult to adjust. Big; third, there are shortcomings in the second control method; third; fourth, there are shortcomings in the second control method four

These shortcomings seriously affect the practical application and promotion of this technology

[0010] To sum up, none of the above three driving control methods can well solve the problem that the actual walking speed of the unit is not synchronized with the seed or fertilizer discharge, resulting in missed seeding and replaying. Therefore, there is an urgent need for better solutions and solutions in this field. alternative
