Definitions

• the invention relates to an agricultural machine for soil cultivation, specifically to an agricultural machine for soil cultivation comprising of a framework construction, in which multiple working units are mounted, wherein the framework construction comprises one central frame, on which are mounted two pivoting side frames, on which are two additional pivoting outer frames.
• An agricultural machine for soil cultivation comprising a framework construction divided into five sections on which multiple working units are mounted is currently known.
• the frame structure is usually divided into sections so that each section contains one part of the framework construction, which are hinged to each- other during transport.
• the framework construction comprises a central frame on which two pivoting mounted side frames are arranged as well, on which two additional pivoting outer frames are mounted. In the transport mode the side frames basically extend straight upwards to the top and, the outer frames are basically arranged straight downwards. This arrangement allows a wide working width machine to be folded to compact dimensions that enable its transport by road.
• the maximum possible height of the frame is directly proportional to the width of the central frame, and this at a ratio of the width of the central frame divided by four. For example, if the central frame is 3000 mm wide, the maximum possible height of each frame is 750 mm. In reality, it is possible to achieve, with a central frame with a width of 3000 mm, a maximum height of the individual frames of 735 mm. In essence, lower frame height means lower clearance, which brings a fundamental disadvantage in that the working depth of the tools is significantly limited because, the greater the height of the frame, including its working units, the greater the depth to which these working units can act on the soil.
• the aim of the invention is the design of agricultural machines for soil cultivation which will enable significantly deeper cultivation than is known from the current technical state-of-the-art.
• Another aim of the invention is to enlarge the space between the lower part of the frame and the soil surface, more precisely its clearance.
• an agricultural machine for soil cultivation specifically to an agricultural machine for soil cultivation comprising of a framework construction, in which multiple working units are mounted, wherein the framework construction comprises one central frame, forming together with the thereon attached working units a first spatial matrix, and on the central frame two pivoting side frames which, together with the thereon attached working units form a second spatial matrix, and on the side frames, two additional pivoting mounted outer frames forming together with the thereon attached working units a third spatial matrix, while in the transport mode the side frames basically extend straight up to the top and the outer frames are basically arranged straight downwards, according to the invention whose principle consists in that in the transport mode the outer frames are so arranged that they mutually penetrate the third spatial matrix, while creating a space for the penetrating member.
• the advantage is that the depth of engagement, or where applicable, the clearance of the frame or the residual clearance to the soil, may increase by at least 1/4 of the height (B) of the penetration space.
• individual working units are mounted in the penetration space to one of the outer frames, each arranged in the free space between the working units mounted on the second outer frame.
• the individual working units are mounted to the side frames mutually asymmetrically in relation to the central axle of the whole machine
• the working units are mounted to the edge of the frame and set in a single row, arranged mutually asymmetrically in relation to the central axle of the whole machine so that the distance (Y) of the working units mounted in a row on one outer frame, as measured from the central axle of the machine, is at least one distance (X) greater or smaller than the distance of the corresponding working units mounted in the same row on the second outer frame, wherein the distance (X) corresponds to the smallest mutual distance between two working units arranged in rows one behind the other in the direction of the machine.
• the mutual distance (Z) between working units mounted in one row corresponds to at least twice the distance (X).
• the individual working units positioned in a row in the driving direction are mutually shifted by up to a distance (W) corresponding to plus or minus twice the distance (X).
• W a distance corresponding to plus or minus twice the distance (X).
• the advantageous height (C) of the individual spatial matrixes is substantially the same.
• the height of the individual frames can vary slightly, for example with respect to the kinematics of folding or with respect to the different dimensions of individual frames. More precisely, it can be said the clearance below all frames should be the same, ie. the height from the lower part of the frame to the tip of the working unit. From the perspective of quality of work, specifically uniformity of work, it is advantageous if the lower parts of the framework construction of individual frames are basically in a plane.
• the advantage of the structural solution according to the invention is maximum possible height of the frame, including the working units mounted thereon, and more specifically its spatial matrix is increased by 1/4 of the height (B) of the penetration space.
• Very advantageous is furthermore a significant increase in the clearance between the frame and the soil surface, thereby significantly increasing throughput of soil and organic residue, and thus, increased resistance to clogging.

• the outer frames 8,9 are arranged so that the third spatial matrixes 10, JM mutually penetrate each-other (Fig. 3), wherein the members form a penetration space 12.
• the individual working units 2 are mounted on one of the outer frames 8,9, in each case arranged in the free space between the working units 2 mounted on the second outer frame 8,9.
• the side frames 4,5 and outer frames 8,9 are pivotally arranged so that as the axles 14 of the pivoting side-frames 4,5, and the axle 15 of the pivoting outer frames 8,9, are set essentially symmetric to the central axle 16 of the entire machine.
• the individual working units 2 are mounted on the outer frames 8,9, essentially mutually asymmetric to the central axle 16 of the entire machine.
