Rotary Ring Soil Trough Test Bench Drive Mechanism

Abstract

The invention discloses a drive mechanism for a rotary annular soil bin test bed, and belongs to scientific research test equipment. A combined inner gear ring is fixedly installed on an annular soil bin; a plurality of central location wheels are assembled on an annular rail support; a drive mechanism support is installed on a base; a variable-frequency and variable-speed motor and a reversing transmission are installed on the drive mechanism support; a rotary seat is installed on a power output shaft of the reversing transmission in a sleeving manner; a drive chain wheel is fixedly installed on the power output shaft; a drive shaft is assembled on the rotary seat; a drive gear and a driven chain wheel are fixedly installed on the drive shaft; a chain is assembled on the drive chain wheel and the driven chain wheel in a sleeving manner; a tensioning chain wheel is assembled on the rotary seat; a return tension spring is connected to the rotary seat and the drive mechanism support; and a drive cylinder is connected to the drive mechanism support and the rotary seat. The mechanism is novel and reasonable in structure, reliable in drive and engagement, high in transmission accuracy, and stable in running, and ensures the test detection accuracy of a working component of an agricultural implement.

Description

technical field [0001] The invention belongs to scientific research and test equipment, and mainly relates to a rotary annular soil tank driving mechanism used in the test of agricultural machinery operation parts. Background technique [0002] Based on many characteristics such as small footprint, compact equipment, high test efficiency, low manufacturing cost, and wide application range, the rotary annular soil tank test equipment has been widely used in agricultural machinery research institutes, which is a great contribution to the improvement of scientific and technological level, Accelerating the maturity of scientific and technological achievements has played a positive role. However, since the existing rotary ring-shaped soil tank drive structure uses the friction between the driving rubber wheel and the rubber ring to drive the ring-shaped soil tank to generate rotational motion, it is found in the practice of scientific research and experiments that the friction be...

However, since the existing rotary ring-shaped soil tank drive structure uses the friction between the driving rubber wheel and the rubber ring to drive the ring-shaped soil tank to generate rotational motion, it is found in the practice of scientific research and experiments that the friction between the rubber wheel and the rubber ring often Slipping occurs due to force changes, resulting in inaccurate and inconsistent rotational speed of the annular soil tank, which affects the accuracy and reliability of the test data of test components such as seed metering devices, and the quality of the test is degraded, making it impossible to make accurate evaluations of the tested components
