Abstract

The invention discloses a storage warehouse fullness reminding and alarming circuit for harvesters, comprising a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a potentiometer, a first capacitor, a second capacitor, a diode, an infrared light emitting diode, an infrared photosensitive transistor, a triode, a relay, a time base chip, a switch, an alarm lamp, a buzzer, and a power supply. During working of the storage warehouse fullness reminding and alarm circuit of the invention, when a warehouse is full of crops, the crops cover the infrared light emitting diode and the infrared photosensitive transistor, the infrared photosensitive transistor cannot receive infrared light and is changed into a high-resistance state to switch on the triode, the time base chip outputs high level to make the relay energized and pulled in, the normally open contact of the relay is switched on, the alarm lamp is lit, and the buzzer sends out alarm sound.

Description

technical field [0001] The invention relates to an alarm circuit, in particular to a warning alarm circuit for a storage bin of a harvester. Background technique [0002] As an integrated machine for harvesting crops, the harvester can complete harvesting, threshing, and concentrate them in the storage bin, which can greatly improve the efficiency of agricultural harvesting, save a lot of manpower and material resources, and contribute to the development of high-efficiency agricultural machinery. But when the harvested crops fill the storage bin of the harvester, if the staff does not find that the storage bin is full and continues to harvest, the harvester will be blocked, or the crops will fall and cause waste. Contents of the invention [0003] The object of the present invention is to provide a storage bin full warning and alarm circuit of a harvester in order to solve the above problems. [0004] The present invention achieves the above object through the following t...
