Storehouse fullness acousto-optical reminding device for grain storage storehouse of combined harvester

Abstract

The invention relates to a storehouse fullness acousto-optical reminding device for a grain storage storehouse of a combined harvester. The storehouse fullness acousto-optical reminding device is characterized by comprising a 12V direct current power supply, an infrared light transmitting circuit, an infrared light receiving circuit, a monostable delay circuit and an acousto-optical reminding circuit, wherein a time-base circuit IC1 in the monostable delay circuit uses a type of NE555. A grain-storehouse storehouse fullness reminding device is additionally arranged at a suitable position at the top of the grain storage storehouse of the combined harvester, utilizes a photocoupling principle to achieve an effect of timely carrying out reminding in an acousto-optical mode when the grain storehouse is full, which is helpful for a driver of the combined harvester to concentrate on driving, and can effectively avoid unnecessary waste caused by scattering of grains in the field. The storehouse fullness acousto-optical reminding device for the grain storage storehouse of the combined harvester, which is disclosed by the invention, not only can be independently developed as a product, but also can be combined onto the grain storage storehouse of a harvester as a standard configuration to be developed in a matching mode.

Description

technical field [0001] The invention belongs to the technical field of photoelectric control, and relates to an acousto-optic warning device for a grain storage bin of a combine harvester when it is full. Background technique [0002] When the combine harvester is working in the field, the driver can only judge whether the grain storage bin is full of grain by observing from time to time or relying on the driver's experience, which can easily distract the driver's attention and cause safety accidents; In the field, it often happens that the grain storage bin of the harvester is full, but it is not discovered in time, causing the grain to be spilled on the field and causing waste; especially when harvesting at night, such things happen particularly prominently. [0003] Therefore, it is necessary to develop a combination harvester grain storage bin full of acousto-optic warning device that is easy to install and use, simple in circuit structure, reliable in work performance, ...
