Experimental study of reclining the cultivator’s paws on spring racks

The article describes the results of experimental determination of the trajectories of the toe of cultivator paws on spring racks of three types: light, medium and heavy. The trajectory was determined by loading on the test bench. It is established that the trajectories are non-linear in nature, and elastic displacements lead to the deepening of the toe of the paw, which violates the established depth of stroke. The loading ranges of the racks are defined, under which the deepening does not exceed the limits of agroadmission. The greatest recession was noted in middle racks, the smallest in heavy racks. It was concluded that it is necessary to monitor the recess of the toe of the feet mounted on the spring post

Dynamic models of cultivator spring tine performance

The article presents results of spring-tine cultivator blade movement modeling. The basic equation of terraelasticity is taken as the initial one. The new model takes into account the spring tine configuration and the vibration mode. It is noted that the model becomes multifrequent. The field reserach confirmed multifrequency and mixed nature of the spring tine vibration spectrum. It is found that the frequency spectrum with technologically relevant vibration accelerations can be more than 1000 Hz. The authors make a conclusion that it is necessary to use high frequencies to improve the quality of spring-tine cultivator blade performance
