Abstract
A synchronous rotary tiller comprises a synchronous power output shaft which is mounted on the small four-wheel tractor, and a drive wheel which is positioned on the synchronous power output shaft and drives vial belts the driven wheel, the power input shaft of the transmission box and the drive chain wheel. The synchronous rotary tiller keeps same forward pitch during operation on the field in case the tractor gear shifts; the added synchronous power output shaft requires a little of change to the original transmission box and the production process, and small amount of put-into-production expense, moreover, the cost is low, only accounting for one tenth of cost necessary for adding a rear power output shaft. The cost of the rotary tiller driven by the synchronous power output shaft equals to two thirds of that of the rotary tiller driven by the rear power output shaft; meanwhile, the maintenance cost is low. The rotary tiller can be conveniently changed into a paring plough if the chain wheel and the cutter tooth of the transmission are replaced. The farm machinery is simple in structure, light in weight, easy to manufacture, and convenient for the enterprise and the farmer to use and repair.
