Prompting device for full granary of harvester

Abstract

The invention provides a prompting device for a full granary of a harvester. The common indicating circuit for the fully loaded granary of the harvester composed of a small incandescent bulb and a photosensitive resistor in the society has the problem of unreliable operation of the circuit caused by greater interference from external light when the circuit works during the day and night and the like. The prompting device can achieve timely prompting a harvester driver in sound and light manners when the granary is filled by adopting an infrared transmitting circuit and an infrared photoelectric receiving circuit, thus facilitating the driver to concentrate on driving with care and effectively avoiding unnecessary troubles resulted from that grains are scattered in fields. The prompting device has the characteristics of convenient installation and use, simple circuit structure, reliable operating performance and low price. The prompting device can be independently developed as a product and developed as configuration to be combined with harvesting machinery in a supporting manner.

Description

[0001] The invention belongs to the technical field of electronics and agricultural machinery, and relates to a grain bin full reminder device for a harvester, which is used for reminding the driver that the grain bin of the harvester is full. Background technique [0002] For a long time, when the loading bin of the harvester is working, whether the loading bin is filled with grain is observed by the driver from time to time, or it is all based on the experience of the driver. In this way, it is inevitable to disperse the attention of some drivers, and it is easy to cause safety hazards; secondly, it often happens that the harvester loading bin is full, but it is not discovered in time, causing unnecessary troubles caused by the grain being thrown into the field; especially This is especially true during the evening rush harvest during the busy season. In the society, there are small incandescent electric beads and photoresistors that are used to indicate the fullness of grai...

Problems solved by technology

In this way, it is inevitable to disperse the attention of some drivers, and it is easy to cause safety hazards; secondly, it often happens that the harvester loading bin is full, but it is not discovered in time, causing unnecessary troubles caused by the grain being thrown into the field; especially This is particularly the case during rush harvest operations at night during the busy season

In the society, there are small incandescent electric beads and photoresistors that are used to indicate the fullness of grain in the load bin. There are problems such as the circuit is greatly disturbed by sunlight during the daytime, which makes the circuit work very unreliable.
