Abstract

The invention relates to a grain bin fullness reminder for a rice-wheat harvester, which comprises a 12V direct-current power source, an infrared transmitting circuit, an infrared photoelectric receiving circuit, a monostable circuit, a control circuit and an acoustical-optical warning circuit. A grain bin fullness remainder is additionally mounted on an upper proper position of a grain bin of the rice-wheat harvester, and a driver can be timely reminded of fullness of the grain bin acoustically and optically by the aid of the photoelectric circuit, so that the driver can concentrate on the field operation, and waste of grains scattering in the field after the grain bin is full can be effectively avoided. The grain bin fullness reminder for the rice-wheat harvester can be used as a product to be developed independently and can be also used as a fitting to be combined to harvesting machinery for development with the same.

Description

The full reminiscences of cereal cabin is cut in the rice wheat harvest

Technical field

The invention belongs to electronics, farm machinery technical field, relate to a kind of harvester for both rice and wheat full granary reminiscences.

Background technology

The granary of harvester for both rice and wheat is when work, and whether granary fills cereal can only be passed through driver's observation frequently, or judges with driver's experiences entirely.Security incident takes place in so easy dispersion driver's notice easily; Two granary of harvester often takes place fills, and does not in time come to light, and causes the unrestrained field of cereal to cause waste; Especially when getting the harvest in quickly operation night, it is particularly outstanding that these things take place.Little incandescent small electric bulb commonly used is filled indicating circuit with the granary cereal of photoresistance composition, exists circuit to work by day to receive the interference of sunlight easily and causes problems such as circuit working is unreliable.

Principle of work: when granary of harvester is not bought securities with all one's capital; Infrared photistor BG1 can receive the infrared light of infrarede emitting diode D1 emission and remain conducting; 2 pin of 555 time-base integrated circuit IC1 are high level, the 3 pin output low levels of 555 time-base integrated circuit IC1, and relay J is in release conditions; Super bright red light emitting diodes LED is not luminous, and hummer HA is sounding not.

When harvester cereal was filled the storehouse, the cereal in the storehouse had sheltered from the infrared signal of infrarede emitting diode D1 emission, and infrared photistor BG1 does not become high-impedance state because of receiving infrared signal; Make 2 pin of 555 time-base integrated circuit IC1 become low level by high level; The monostable circuit upset makes 3 pin of 555 time-base integrated circuit IC1 export high level, and at this moment relay J gets electric adhesive; Its normally opened contact is connected; Super bright emitting red light two utmost point LED are lighted, and buzzer HA sounding is reminded the harvester driver simultaneously through acousto-optic.；

Technical characterictic: harvester for both rice and wheat full granary reminiscences, to form by 12V direct supply, infrared light radiating circuit, infrared electro receiving circuit, monostable circuit and control circuit, acousto-optic alert circuit, its characteristic comprises:

Infrared light radiating circuit: form by infrarede emitting diode D1, potentiometer RP; The negative pole connection circuit ground GND of infrarede emitting diode D1; The positive pole of infrarede emitting diode D1 connects the end of potentiometer RP, the other end of potentiometer RP and movable knee-joint 12V dc power anode VCC thereof;

Infrared electro receiving circuit: form by infrared type photistor BG1, resistance R 1; The emitter connection circuit ground GND of infrared type photistor BG1; The collector of infrared type photistor BG1 connects 2 pin of 555 time-base integrated circuit IC1 and an end of resistance R 1, another termination 12V dc power anode VCC of resistance R 1;

Monostable circuit and control circuit: form by 555 time-base integrated circuit IC1, resistance R 2 and electrochemical capacitor C1, relay J and silicon diode D2; The end of 6 pin of 555 time-base integrated circuit IC1 and 7 pin connecting resistance R2, the positive pole of electrochemical capacitor C1; Another termination 12V dc power anode VCC of resistance R 2; The negative pole connection circuit ground GND of electrochemical capacitor C1; 4 pin of 555 time-base integrated circuit IC1 and 8 pin meet 12V dc power anode VCC, and 3 pin of 555 time-base integrated circuit IC1 are succeeded an end of electrical equipment J coil and the negative pole of silicon diode D2, the anodal connection circuit ground GND of the other end of relay J coil and silicon diode D2;

Acousto-optic alert circuit: form by super bright red light emitting diodes LED, resistance R 3 and hummer HA; The negative pole of the termination hummer HA of relay J normally opened contact J-1 and the negative pole of super bright red light emitting diodes LED; The end of the anodal connecting resistance R3 of super bright red light emitting diodes LED; Another termination 12V dc power anode VCC of the positive pole of hummer HA and resistance R 3, the other end connection circuit ground GND of relay J normally opened contact J-1.
