High-speed rice transplanter comprehensive performance detection test stand

Abstract

The invention discloses a high-speed rice transplanter comprehensive performance detection test stand comprising a main frame body of the test stand, a guide rail, a supporting plate, a motor, a transplanting mechanism, a box moving mechanism, a seeding box, a miss planting rate detection device, a spiral shaft mechanical impact detection device, a transplanting mechanism seeding needle movement track synchronization performance detection mechanism, an industrial control box and a portable computer. The planting part of a transplanter is formed by the transplanting mechanism, the box moving mechanism and the seeding box. Forward, backward, stop and planting conditions of the planting part can be controlled through the portable computer and the industrial control box. The movement tracks of the transplanting mechanism seeding needle can be captured in real time by adopting a symmetric CMOS camera. Counting of the miss planting rate is performed by a soil loading bin outputted by a conveying belt through four photoelectric sensors. A mechanical impact sensor group which is installed on a spiral shaft and formed by an impact acceleration sensor and a stress detector acquires acceleration of a slide sleeve and strain information under the impact load so as to analyze the performance of the box moving mechanism.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a comprehensive performance detection test bench for a high-speed rice transplanter. Background technique [0002] If there are product defects in the high-speed rice transplanter, it is easy to affect its working performance and service life, so the high-speed rice transplanter must be tested for performance before leaving the factory. At present, in the field of performance testing of high-speed rice transplanters, the testing functions of the test benches are mostly limited to the performance parameter testing of individual parts of the box-moving mechanism or the splitting mechanism, while the test benches for comprehensive performance testing of high-speed rice transplanters are relatively rare. In order to accurately analyze the comprehensive performance of the various mechanisms of the high-speed rice transplanter in the transplanting operation and measure the main perfo...
