Abstract

The utility model discloses a heating control device used for a grain drying machine. The heating control device includes a grain heating current detection module (1) which detects the working current of a heater, a grain heating voltage detection module (2) which detects the working voltage of the heater, a grain heating controller (3) which controls the heating time of the heater and an input module (4) which can set the number of to-be-dried grain in the grain drying machine. The grain heating controller (3) is connected with the control terminal of the heater. The grain heating controller (3) calculates the heating total power needed by the to-be-dried grain according to the number of the to-be-dried grain input by the input module (4), and controls the working current, the working voltage and the heating time of the heater according to the heating total power. The heating control device used for the grain drying machine has the advantages of simple and convenient operation, high intelligence, simple structure and low cost, and dose not rely on the personal experience of an operator.

Description

A kind of heating control apparatus for grain drier

Technical field

The utility model relates to agriculture field, is specifically related to a kind of heating control apparatus for grain drier.

Background technology

Heating is one of dry means commonly used of grain drier.If but heat time heating time, control was bad, in case over-heating occurs, then affect the characteristic of grain own, cause the mouthfeel of grain, the forfeiture of nutrition; If heat time heating time is inadequate, then may cause grain drying inadequate, easily cause the problem such as go mouldy.But, the grain drier of prior art add heat control by manually carrying out, inefficiency too relies on operating personnel's personal experience.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of simple to operation, degree of intelligence is high, do not rely on operating personnel's personal experience, the heating control apparatus that is used for grain drier simple in structure, with low cost.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of heating control apparatus for grain drier, comprise grain for detection of the well heater working current current detection module that is heated, for detection of the grain of the well heater operating voltage voltage detection module of being heated, be used for the load module that the grain of control heater heat time heating time is subjected to heat controller and is used for arranging Grain Quantity to be dried in the grain drier, described grain is linked to each other with the control end of well heater by heat controller, described grain is subjected to heat controller to calculate the required heating general power of grain to be dried according to the Grain Quantity to be dried of load module input, and comes the working current of control heater according to described heating general power, the heat time heating time of operating voltage and control heater.

As further improvement in the technical proposal:

The utility model also comprises the temperature sensor for detection of grain drier internal work temperature, the output terminal of described temperature sensor is linked to each other by heat controller with grain, described grain is subjected to heat controller to come the frequency of unlatching and the disconnection of control heater according to grain drier internal work temperature.

The utlity model has following advantage:

1, grain of the present utility model is subjected to heat controller to calculate the required heating general power of grain to be dried according to the Grain Quantity to be dried of load module input, and the heat time heating time of coming working current, operating voltage and the control heater of control heater according to described heating general power, thereby can control degree of heat from gross energy, guarantee that grain to be dried can too much or very fewly not cause grain to damage or goes mouldy owing to being heated, have advantages of simple to operation, degree of intelligence is high, do not rely on operating personnel's personal experience, simple in structure, with low cost.

2, the utility model further comprises the temperature sensor for detection of grain drier internal work temperature, the output terminal of temperature sensor is linked to each other by heat controller with grain, grain is subjected to heat controller to come the frequency of unlatching and the disconnection of control heater according to grain drier internal work temperature, the frequency of unlatching and disconnection by control heater, the temperature that can prevent well heater is too assembled, and can prevent the problem that grain to be dried causes grain to damage owing to too much heat.
