DEVICE FOR DRIVING TILLAGE TOOL ALONG PLANT ROWS Russian patent published in 2013 - IPC A01B69/00 

FIELD: agriculture.

SUBSTANCE: device comprises spring-loaded gauge probes kinematically connected to the hydraulic system comprising flat-rotary directional hydraulic valve and actuating hydraulic cylinder controlling the location of the working bodies of the tillage tool. The kinematic connection of the gauge probes with the hydraulic system is made in the form of a "П"-shaped frame consisting of articulated central and two lateral parts, with the gauge probes fixed on it at the lower part and oriented along the direction of motion. The central part of the "П"-shaped frame is connected by means of the lock to the shaft kinematically connected with spool of the hydraulic distribution valve, and its lateral parts are provided with additional drafts forming parallelogram mechanisms pulled together by a spring. The central part is equipped with stops placed inside the "П"-shaped frame and interacting with its side parts.

EFFECT: device significantly improves the quality of work and productivity, for example, in disclosure of the root system of clonal rootstocks prior to their separation from the mother plants.
