Upgraded rotary harrow for vineyards

Abstract

To improve the quality of surface loosening, it is necessary to search for new approaches to soil maintenance and solving problems related to the reproduction of soil fertility, maintaining production volumes. In this connection, in order to increase operational reliability, simplify the design and clean the teeth from weed stalks in the basic technical tool, which includes a frame in the form of a beam equipped with a suspension system with mounted teeth. The teeth are made of a rectangular strip section, with a bend, with an oval surface on the side opposite to the direction of the bend and a formed arrow-shaped tip. They are placed on batteries of rigidly fixed disks. The teeth have reinforcing annular plates, which are located on the free length of the teeth, and their width is made at least equal to the width of the teeth. The cam element is made in the form of a cylindrical ring equipped with a rounded recess. The use of a modernized rotary harrow in the inter-row spacing of vine-yards will increase the operational reliability and quality of surface loosening, as well as simplify the design and clean the teeth from weed stalks.
