Abstract

FIELD: agricultural engineering; plows with adjustable width for operation with tractor moving in furrow by wheels of one side. SUBSTANCE: plow has frame in form of articulated triangle consisting of turning beam with fitted on plow bodies installed for turning on vertical axles, front bar with crossmember installed for movement along bar and provided with couplers for connection to hinge joints of lower arms of tractor hitch linkage and adjustable length tie-rod. Front hinge joint of tie-rod is mounted on crossmember close to hinge joint of lower arm of hitch linkage. Hinge joints of tie-rod and center of resistance of plow bodies installed on turning beam are arranged in one vertical plane. EFFECT: increased strength of plow, reduced mass and energy consumption. 2 cl

Claims (1)

The invention relates to agricultural machinery, in particular, to plows with a variable working width, mainly for working with a tractor moving the wheels of one side along the furrow. The plow contains a frame in the form of an articulated triangle, consisting of a pivot beam with plow bodies mounted on it rotatable on vertical axes, a front beam with a cross member moving along it, which has elements for connecting to the lower link hinges of the linkage of the traction means and couplers of adjustable length. The front hinge of the coupler is located on the cross member in the immediate vicinity of the hinge of the lower link of the linkage. The hinges of the coupler and the center of resistance of the plow bodies mounted on the swing beam are located in one vertical plane. The proposed design made it possible to increase the strength of the plow and reduce its weight and, as a result, reduce energy consumption.
