Test device for bridge chain harrow loading

Abstract

The invention relates to a test device for bridge chain harrow loading, and belongs to the related technical field of agricultural machinery. The test device comprises a motor, a gap bridge driving shaft, a gap bridge main body, a loading shaft and a hydraulic loading system, the gap bridge driving shaft and the loading shaft are respectively installed on the gap bridge main body, the motor is in transmission connection with the gap bridge driving shaft through a transmission belt, and a safety clutch is installed on the gap bridge driving shaft. The gap bridge driving shaft drives a conveying chain of the gap bridge chain harrow to operate through a driving chain wheel, and the conveying chain is meshed with the loading shaft; and the hydraulic loading system is in transmission connection with the loading shaft through a transmission shaft. The hydraulic loading system is used for loading different loads experienced during field operation on the loading shaft, so that rapid loading test and limit working condition simulation can be realized, resistance is provided for operation of the conveying chain, the service life of the conveying chain is tested, and the reliability and the bearing performance of the gap bridge chain harrow conveying chain can be confirmed and the wear degree of each part can be checked according to the total accumulated operation time of the conveying chain.

Description

technical field [0001] The invention relates to the relevant technical field of bridge-crossing tests, in particular to a test device used for bridge-crossing chain rake loading. Background technique [0002] At present, the field test is mainly carried out for crossing the bridge, and the service life of the conveyor chain cannot be compared under the same working conditions. In addition, field trials are greatly affected by the crop planting season, and the trial period is long, resulting in a longer time to market for products. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a test device for loading a bridge chain rake in view of the deficiencies of the prior art. [0004] The technical solution of the present invention to solve the above technical problems is as follows: a test device for loading a bridge chain rake, comprising a motor, a bridge driving shaft, a bridge main body, a loading shaft and a hydrau...
