Description

Agricultural machine Technical Field The present invention relates to an agricultural machine. Wherein the agricultural machine, in particular a planter and/or a soil reclamation machine, comprises at least one support frame and at least one, in particular multipart, bearing arrangement, wherein the at least one support frame is associated with the machine and comprises at least one receptacle such that the at least one cross beam is substantially transverse to the direction of travel of the machine, wherein the cross beam is arranged at the receptacle via the bearing arrangement such that it can rotate at least partially about its longitudinal axis, wherein the bearing arrangement comprises at least one housing element, in particular seen in the circumferential direction, which comprises an outer side facing the receptacle and an inner side facing the cross beam, wherein at least one compensation body is arranged between the inner side and the cross beam, and wherein the cross beam is connected to the bearing arrangement, in particular to the housing element, in a rotationally fixed manner by means of the at least one compensation body. Background Various types of traction, mounted, and/or self-propelled machines are known in the agricultural arts. In addition to a planter adapted for spreading distribution material, in particular seeds and/or fertilizer, over an agricultural arable land, agricultural machines also include soil reclamation machines by which surface soil of such arable land can be reclaimed and/or post-treated. The agricultural machine further includes a tilling combine comprised of a planter and a soil reclamation machine, the tilling combine configured to combine the distribution of the spread material and reclamation of the tillable area. For the corresponding spreading of the distribution material on the arable land or the corresponding treatment of the arable land, such agricultural machines comprise at least one work tool suitable for this purpose and suitably coupled to the support frame of the implement. Depending on the attitude of the machine, in particular between the working and/or transport attitudes, and/or depending on the desired working or penetration depth, the universal working tool can be positioned and/or moved at least partially to different heights. For this purpose, the work tool, in particular as seen in a travel direction transverse to the machine, is arranged to be adjustable in height, position and/or direction by means of at least one, in particular common, cross beam coupled with the machine. A general machine is described, for example, in EP3649841 A1. The machine includes at least one support frame associated with the machine and having at least one receptacle such that at least one cross beam is substantially transverse to a direction of travel of the machine. Furthermore, the machine comprises at least one, in particular multipart, bearing device, by means of which the cross beam is arranged at the receiving portion so as to be at least partially rotatable about its longitudinal axis. The bearing arrangement further comprises a housing element, in particular seen in the circumferential direction, which comprises an outer side facing the receiving portion and an inner side facing the cross beam. Furthermore, at least one compensation body is arranged between the inner side and the cross beam, by means of which the cross beam is connected in a rotationally fixed manner to the bearing arrangement, in particular to the housing element. A problem with such machines constructed in this way is, inter alia, the manner in which the support frame, in particular the bearing arrangement, is coupled to the cross beam. In an embodiment variant, the compensation body is connected to the transverse beam in particular in a completely form-fitting manner, which is particularly disadvantageous because of the associated and/or necessary play between the bearing device, in particular the compensation body, and the transverse beam. This results in particularly high, in particular additional, loads on the bearing device and/or the cross beam, in particular in the event of load changes and/or fluctuations, which in turn have a negative effect on the operational safety of the machine. In a further embodiment variant, the compensation body is connected to the transverse beam in a form-fitting manner, in particular in a welded connection, which is disadvantageous because of the lack of adaptability to the particular axial position of the connection of the compensation body to the transverse beam. In this case, a subsequent adjustment of the position of the cross beam relative to the support frame of the machine is not possible at all, or is only possible with considerable effort. Disclosure of Invention It is therefore an object of the present invention to devise a machine such that the described drawbacks are at least partially eliminated. In particular, a particularly variable conn
