Grain flow sensor test bench

Abstract

The invention relates to a grain harvesting machine, in particular to a grain flow sensor test bench, which is characterized in that the test bench consists of a rack, an auger and elevator assembly, a grain feed device capable of adjusting grain feed, a grain discharge device and a power system, wherein the grain feed device and the grain discharge device are installed at the upper part of the rack, the auger part of the auger and elevator assembly is installed at the lower part of the rack and is arranged right below the grain discharge device, the grain outlet of the elevator of the auger and elevator assembly is aligned to the inlet of the grain discharge device, the power system is installed at the lower part of the rack, a weighing sensor is installed on a grain feed box of the grain feed device, and a grain flow sensor is arranged at the grain outlet of the elevator of the auger and elevator assembly. Grains are delivered to the grain outlet of the elevator through the power system which drives the auger and the scraper elevator and collide with the impact-type grain flow sensor to form sensing signals; and moreover, the grains in the grain feed box are dynamically weighed, and the system control of the grain flow sensor development test bench is realized.

Description

technical field [0001] The invention relates to a grain harvesting machine, and mainly aims at developing and designing a scraper-type elevator for calibrating a grain flow sensor and a test bench for a grain flow sensor with a large feeding amount. Background technique [0002] Among the commonly used production measurement systems in China, the elevators are mainly of the scraper type and the auger type. In order to study the stability of the production measurement system based on this, the development of the grain flow sensor test bench has become one of the very important basic devices. , while the existing domestic grain monitoring systems are all experimentally researched on a simple test bench, the research on the entire yield measurement system is not comprehensive enough, and the development of the test bench is still not perfect; while foreign countries, such as the simple and simple ones developed by M. Convenient grain flow sensor test bench, which is developed c...

[0002] Among the commonly used production measurement systems in China, the elevators are mainly of the scraper type and the auger type. In order to study the stability of the production measurement system based on this, the development of the grain flow sensor test bench has become one of the very important basic devices. , while the existing domestic grain monitoring systems are all experimentally researched on a simple test bench, the research on the entire yield measurement system is not comprehensive enough, and the development of the test bench is still not perfect; while foreign countries, such as the simple and simple ones developed by M. Convenient grain flow sensor test bench, which is developed centering on the auger and scraper elevator of John Deere 7700 combine harvester, can be tested in the laboratory and field, using GPS time synchronization information, load cell signals, etc. Large-scale data for reference research on flow sensor data, but it is not suitable for the structural characteristics of domestic scraper elevators, and the system accuracy is not high
