DEVICE OF AUTOMATIC REGULATION OF THE WORKING WIDTH OF THE FIRST BEACH CASE WITH ACCOUNT OF THE VARIABLE WORKING WIDTH OF THE FOLLOWING BEACH CASES

摘要

A device for automatic regulation of the working width of the first plow body (111) of the plow (1) in accordance with the variable working width of the subsequent plow bodies (112, 113), in which the first hydraulic cylinder (13) is configured to shift the rear section (117) of the frame sideways the front section (116) of the frame, and the second hydraulic cylinder (14) is configured to rotate the rear section (117) of the frame around the first vertical pivot axis (119) to control the separation of the plow bodies (111, 112, 113) in the transverse direction by rotating the plow bodies (111, 112, 113) around the second vertical pivot axes (115), the first hydraulic cylinder (13) is a multi-stage cylinder, in which the first stage (131) of the cylinder provides the main lateral control, and the second stage (132 ) cylinder provides automatic control of the working width of the first plow body (111), the second stage (132) of the cylinder is hydraulically communicated in fluid with the second hydraulic cylinder (14) in a master-slave configuration, with the second stage (132) The cylinder is driven or driven depending on the direction of travel of the cylinder stage (132), while the second hydraulic cylinder (14) is driven or led, respectively, and the diameters (D, D) of the second stage pistons (132) of the cylinder and the second hydraulic cylinder (14). ) correspond to each other in such a way that the adjustment of the working width of the plow bodies (111, 112, 113) by the second hydraulic cylinder (14) ensures the adjustment of the lateral displacement of the front section (116) of the frame.
