EXPLORE THE MECHANISMS OF UREA POINT DEEP APPLICATOR FOR PADDY FIELD

This paper describes the structure and working priciple of the urea point deep applicator for paddy field, proposes the designed idea of point deep placement of urea, analyses both characteristics and results of feed auger’s "planet" motion, and solves difficult problems, just as water "following" into the hopper etc. On this basis we designed urea point deep applicator, the performance of which came up to advanced standards.
