The invention relates to a resistance testing device capable of continuous operation, and belongs to the technical field of agricultural machinery testing. The resistance testing device comprises a soil box system, a depth regulating system, a resistance testing system and a supporting system, wherein the soil box system is positioned at the bottom of the whole device; the resistance testing system is positioned above the soil box system; the depth regulating system is positioned on two sides of the resistance testing system; and the supporting system is positioned at the middle part of the resistance testing system and is positioned between two regulating supports of the depth regulating system. The device can realize indoor resistance testing without being influenced by external factorssuch as weather and landform, and the testing conditions are easy to control. Secondly, the state of continuous operation in actual production can be simulated relatively accurately through continuousoperation of a testing shovel and a soil back scraping plate. And then, the testing depth is adjustable, the operation is of tensioning supporting, and the device is simple in structure and easy to regulate. The device is high in universality, soil cultivation can be carried out continuously, efficiently and conveniently to obtain component resistance testing, and the device has good promotionalvalues.
