The automatic control device mainly aims at solving the problem that the existing control system of the seed coater is low in automation degree, complex in operation and discordant and inaccurate in seed and medicine liquid supply. The control device utilizes a single chip microcomputer, an intelligent sensor, a frequency converter and the like as main parts. The control device is mainly composed of the single chip microcomputer, a keyboard/ displaying circuit (2), a feeding motor (3), a liquid supply motor (4), a solid flow meter (5), a medicine liquid detector (6), an auger motor (7), a projecting disc motor (8), an analog/digital (A/D) converter (9), a power supply circuit (10), a resetting circuit (11) and a clock circuit (12). The automatic control device of the seed coater has the functions of input detection, operation processing, control output and human-computer interaction. By means of acquisition and processing of external data, accurate detection and optimization of key parameters and a real-time process control system, the automatic control device better achieves accurate control of seed quantity and medicine liquid quantity, improves seed and medicine supply accuracy, improves coating operation quality and enables the seed coater to have optimum processing quality.
Description
Technical field
The invention belongs to the seed processing machinery field for the control device of seed pelleting machine.
Background technology
Traditional dressing machine control system is simply extensive, does not guarantee to plant the range of adjustment of medicine ratio, and seed and the kind clothing agent feed quantity coefficient of variation do not reach requirement, and seed and the agent of kind clothing can not arrive the range of atomization according to rational order, have a strong impact on the dressing qualification rate.
The present invention is with singlechip technology, and sensing detection technology and converter technology combine and be applied in the control device of seed pelleting machine, makes whole dressing process controllable.Sensor obtains the essential information of dressing operation, mainly be that seed and soup supply with whether normally reach the quantity delivered size, the conversion of circuit conditioning is transferred to single-chip microcomputer after testing, single-chip microcomputer is done after storage, processing, the analysis to this information, send control information, process is changed the frequency that modulate circuit is regulated frequency converter, and then the speed of feeding and feed flow motor is adjusted, and namely exactly feeding capacity and liquid supply rate is accurately controlled.
Summary of the invention
What the present invention was primarily aimed at is that traditional dressing machine control system is simply extensive, do not guarantee to plant the range of adjustment of medicine ratio, seed and the kind clothing agent feed quantity coefficient of variation do not reach requirement, seed and the agent of kind clothing can not arrive the range of atomization according to rational order, have a strong impact on the problem of dressing qualification rate, proposed SCM Based seed pelleting control device.This device mainly by single-chip microcomputer, keyboard/display circuit, frequency converter, solid flowmeter, soup detecting device, screw feeder motor, get rid of coil motor, power circuit, reset circuit, clock circuit etc. and form.The seed pelleting machine automaton is divided into input according to function and detects, calculation process, control output and man-machine interaction.Wherein single-chip microcomputer is selected the strong Atmeg128 of antijamming capability, and input detecting circuit and output control circuit have isolation, improve the reliability of this device.Collection and processing by external data, accurate detection and the optimization of key parameter, and real-time process control system realize the accurate control of seed, amount of liquid medicine better, improve accuracy and the dressing operation quality of seed and confession medicine, thereby given play to the optimal process quality of equipment.
