Design and Experiment of Uniformity Cutting Device of Carrot Harvester

Uniformity cutting device is an important component of carrot harvester.Its performance influences the condition of incision position and cutting uniformity directly.According to agronomic requirements and planting patterns of carrots，a double disc uniformity cutting device applied to double-row carrot harvester was designed successfully.This device was mainly composed of uniformity parts，cutting component，horizontal clamping and conveying component and etc.Uniformity，cutting and throwing operation could be completed simultaneously.Double disc cutter as cutting part could insure smooth incision appearance and good cutting effect.Baffle was uniformity component and its height and middle gap size was adjustable.Horizontal clamping conveying unit with upper and lower two layers sandwiched belt，which could effectively prevent carrot seedling leaves falling and be conducive to subsequent cutting and transplanting operation.Successful development of this device solved several problems of carrot mechanical harvest，such as incision was not beautiful，lacy effect was not good and plug seedling.At the same time，this device could effectively improve harvest effect of carrot harvester.
