Abstract

The invention discloses a performance detecting system for a seeding mechanism, which comprises a controller used for controlling the operation of a seeding mechanism test bed and a seeding mechanism detecting system, a speed monitoring unit which carries out data communication with the controller and is used for measuring and controlling the speed of motors, and an image acquisition unit which carries out data communication with the controller and is used for acquiring data. The system of the invention monitors the speed of various motors through the speed monitoring unit and can utilize the controller to regulate the speed of various motors, thereby obtaining more reasonable test results; besides, the system of the invention can obtain video data and image data during the seeding test process through the image acquisition unit, thus analyzing the test results more clearly and intuitively. The system of the invention realizes automatic monitoring over the seeding mechanism test bed and the accurate measurement of seeding data and has the advantages of simple structure and convenient and fast operation.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a seed metering device detection system. Background technique [0002] The seed meter test bench is the main means used in the research and development of seeders, and it is an indispensable test equipment for the rapid production of a new generation of high-performance seeders. The seed meter test bench should be able to complete the main test contents stipulated in the national standard GB 6973-1986 "Test Method for Single Grain (Precision) Seeder" and GB / T 9478-1988 "Test Method for Grain Drill". However, due to the low degree of automation, the imperfect detection method of the seed particle distance and the backward data processing method of the currently used seed metering test bench, sometimes it is necessary to manually participate in the measurement of the seed metering test results and manual tabulation, which requires a lot of manpower and labor. time, and the ac...
