Embodiment Construction

[0021] The method for testing the feeding amount of the bellows according to the present invention: the bellows is composed of a diaphragm and a sensor seat, a sensor for testing the displacement of the diaphragm is arranged in the bellows to form a feeding amount sensor of the bellows, and the feeding amount sensor of the bellows is installed The bottom plate at the bridge exit of the combine harvester bears the extrusion force of the bridge conveying and feeding crops, and converts the extrusion force (diaphragm displacement) signal into an electrical signal to test the feed amount of the combine harvester. This method can also be called the diaphragm displacement feeding amount test method, and its working principle is as follows: figure 1 Shown:

[0022] When the combine harvester is harvesting in the field, the mature crops cut by the harvesting table are transported to the main engine through the bridge for threshing, separation and cleaning, and the crop grains are harv...

Abstract

The invention discloses a method for testing feeding quantity of bellows of combined harvester, a device and a feeding quantity sensor. The bellows (composed of a diaphragm and a sensor base) is internally collocated with an electric turbulent flow sensor or weighting transducer to form a bellows feeding quantity sensor. The bellows feeding quantity sensor is installed on the base at the gap bridge outlet of combined harvester to form a bellows feeding quantity testing device for bearing the extrusion pressure of gap bridge conveying and crop feeding. The extrusion pressure (diaphragm displacement amount and diaphragm displacement force) signals are converted to electric signals and are transmitted to a feeding quantity observing and controlling instrument for testing the feeding quantity of combined harvester and facilitating the production efficiency control of combined harvester. The bellows feeding quantity sensor of the invention has the advantages of simple installation, convenient use, high sensitivity, accurate test, rain resistance, humidity resistance and strong practicability.

Description

Technical field: [0001] The invention relates to a method and device for testing the feeding amount of a combine harvester, and a feeding amount sensor, belonging to the technical field of agricultural equipment monitoring and the technical field of sensors. Background technique: [0002] The combine harvester is an important technical equipment to realize agricultural mechanization and agricultural modernization. "Feeding amount" is an important design parameter and performance parameter of the combine harvester. For the test of the feeding amount of grain harvesting machinery, manual or auxiliary devices are usually used to sample, and the total mass of the sample is divided by the sampling time to obtain the average feeding amount of the grain harvesting machinery over a period of time. However, this method cannot be used for real-time testing of the random feeding amount of grain harvesting machinery that is being harvested in the field. [0003] During the harvest sea...
