Precaution and alarming device for combined harvester plugging fault

Abstract

The invention relates to a precaution and alarming hardware device for combined harvester plugging fault when in harvesting, belonging to the technical field of the agricultural machinery electronic equipment and comprising the following components: a sensor module, an analog signal processing module, a signal converting module, a power supply module, a singlechip central information processing unit module, a liquid crystal display (LCD) module, a tri-color LED fault grading display, and an upper computer communication module. The device provided in the invention can be assembled into the cab of the combined harvester, so when in harvesting, the device can perform real-time precaution and alarming on a threshing cylinder and a grain-delivering auger parts, and promptly provide state information of the harvester for the driver to prevent plugging fault from occurring.

Description

Technical field: [0001] The invention relates to a blockage fault early warning and alarm device for a combine harvester, which belongs to the technical field of agricultural machinery and electronic equipment, and is particularly suitable for early warning and alarm of blockage faults of a threshing drum and a grain conveying auger when the combine harvester is harvesting in the field . Background technique: [0002] When the combine harvester is harvesting in the field, blockage failure is one of the common failures. Once a blockage occurs, it is generally time-consuming and labor-intensive to remove the blockage. In severe cases, it will cause mechanical failure and require downtime for maintenance, which will directly affect the harvesting season and the economic income of the operator. [0003] For combine harvester blockage faults, the technical level at home and abroad is still limited to simple alarms, and there is a lack of systematic research and development of re...

Problems solved by technology

Once a blockage occurs, it is generally time-consuming and labor-intensive to remove the blockage. In severe cases, it will cause mechanical failure and require downtime for maintenance, which will directly affect the harvesting season and the economic income of the machine operator.

[0003] For combine harvester blockage faults, the technical level at home and abroad is still limited to simple alarms, and there is a lack of systematic research and development of related fault diagnosis technologies, methods and theories

According to the data (He Satellite, Zhang Ligong, Zhang Jixian, combine harvester fault warning device (P), utility model patent, application number: 97203354.8, publication number: CN2325968, date of issuance: 1999.04.15, main classification number: A01D73 / 00 ), at present the main method adopted for blockage alarm is speed monitoring. When the speed exceeds the rated range, an alarm signal is sent. Poor adaptability to active changes limits its application

Another method is to use the method of torque measurement. This method is more reliable in principle than only measuring the speed of the alarm. Promote on Combine Harvesters
