Abstract

A combined plough and soil preparation apparatus is described, said plough, which preferably is a more-furrowed turning plough (2), for instance a four-furrowed turning plough, at a foremost combined pull and turning head (12) being adapted to be connected to a lift (10) of a tractor (8), where a central girder (4) for the plough is pivotally mounted in a carrying frame (6), the frontmost end of which comprises said combined pull and turning head (12), and the hindmost end of which comprises a rear turning head (16) for the girder (4) of the plough, which carrying frame (6) preferably near said hindmost end at both sides is provided with wheels (18), preferably with rubber tyres, which alternately operate as depth or land wheels driving on the unploughed soil, and as easy loaded or preferably unloaded wheels driving in the newploughed soil, and that said hindmost part of the carrying frame (6) furthermore comprises coupling means for one or more after-coupled soil preparation apparatuses, for instance an earth packer (20), a sowing machine or a combined sowing machine and fertilization equipment. By means of simple provisions an improved half-towed turning plough is obtained, which compared to corresponding lift-mounted turning ploughs with same capacity may be towed by a ligther and cheaper tractor.

Description

Combined plough and soil preparation apparatus
The present invention relates to a combined plough and soil preparation apparatus of the type described in the introductory part of claim 1.
In relation with lift-mounted and/or half -to wed turning ploughs it is known, that it might be problematic to work with after-coupled soil preparation apparatuses. In particular at the respective ends of the field technical problems during the turnings occur, because it by means of complicated coupling means is necessary temporarily to uncouple and couple on after-coupled apparatuses. It is furthermore a disadvantage that known turning ploughs, where it is possible to after-couple soil preparation apparatu- ses, demand use of very strong and expensive tractors, which furthermore because of their net weight increase the risk for so-called "traktose", that is where heavy traffic compress the soil.
The invention has for its purpose to provide an improved plough and soil preparation apparatus of the type mentioned in the introductory part, and which makes it possible to meet the said disadvantages.
The plough according to the invention is distinctive in that a central girder for the plough is pivotally mounted in a carrying frame, the frontmost end of which comprises said combined pull and turning head, and the hindmost end of which comprises a rear turning head for the girder of the plough, which carrying frame preferably near said hindmost end at both side is provided with wheels, preferably with rubber tyres, which alternately operate as depth or land wheels driving on the unploughed soil, and as easy loaded or preferably unloaded wheels driving in the new-ploughed soil, and that said hindmost part of the carrying frame furthermore comprises coupling means for one or more after-coupled soil preparation apparatuses, for instance an earth packer a sowing machine or a combined sowing machine and fertilization equipment. By means of simple provisions an improved half-towed turning plough is obtained, which compared to corresponding lift-mounted turning ploughs with same capacity may be towed by a lighter and cheaper tractor, and which does not cause said uncoupling and coupling problems in connection with the turnings at the respective ends of the field.
Appropriately the plough according to the invention may be such provided, that said coupling means for said after-coupled soil preparation apparatus comprises a preferably hydraulic operated arm system, being such adapted that the said wheel driving in the new-ploughed soil may be totally relieved.
Most advantageously the plough according to the invention may furthermore be such provided that between the carrying frame and said wheels means are inserted being adapted to height-adjustment of the carrying frame in relation to the surface of the soil.
The plough according to the invention is furthermore preferably such provided that at least one of the turning heads for the girder of the plough is adapted to be sidewardly displaced, preferably by means of one or more hydraulic cylinders.
The plough according to the invention may furthermore advantageously be such provided, that the carrying frame at least on level with the driving wheels is higher in order to limit the maximum width of the plough in the transport position, that is such that the driving wheels may be placed under the carrying frame.
The invention is explained in more detail in the following with reference to the drawing, in which: -
Fig. 1 shows a preferred embodiment for a plough according to the invention,
Fig. 2 shows a modified embodiment for a plough according to the invention,
Fig. 3 shows the plough shown in Fig. 1 according to the invention in the working situation, that is during combined ploughing and soil preparation,
Fig. 4 shows a side view of the plough in the working situation,
Fig. 5 shows a side view of the plough during lifting to the shifting or transport position shown in Fig. 6,
Fig. 6 shows a side view of the plough in shifting or lifted working position,
Fig. 7 shows a side view of the plough during turning or transport,
Fig. 8 shows the plough - seen from behind - in shifting or lifted working position, Fig. 9 shows the plough - seen from behind - during ploughing cf. Fig. 4,
Fig. 10 shows the plough - seen from behind - during turning or transport cf.
Fig. 7, and
Fig. 11 shows the plough - seen from behind - in shifting or lifted working position cf. Fig. 6.
The shown preferred embodiment for a plough according to the invention is cf. Figs. 1 and 3 - 11 provided as a four-furrowed turning plough 2 with a girder 4 being pivotally arranged in a carrying frame 6 being adapted to be coupled on a tractor 8 via its lift 10, said carrying frame 6 comprising a foremost turning head 12, which as shown with dotted line furthermore is adapted to be sidewardly displaced. Via an angel part 14 the carrying frame furthermore cooperates with a rear turning head 16, which also may be adapted to be sidevardly displaced. The carrying frame 6 has at the back height adjustable driving wheels 18, which alternately operate as combined depth and land wheels driving on the un-ploughed soil, and as light loaded or unloaded wheels driving in the new-ploughed soil (Fig. 3).
Fig. 2 shows an alternative embodiment for the plough according to the invention, where the foremost turning head is not adapted to be sidewardly displaced, that is where the common girder for the plough blades is angular adjusted by turning of the plough girder around the rear turning head.
Figs. 4 - 6 show how the turning plough 2 may be height-adjusted from working position (Fig. 4) to transport - or turning position (Fig. 6) by means of the lift 10 of the tractor and by height adjustment of the driving wheels 18 in relation to the carrying frame 6.
Figs. 4 and 8 show the turning plough in working position; while Figs. 7 and 10 show the turning plough 2 in the transport position.
Figs. 9 and 11 shows the turning plough 2 with the girder 4 in a lifted working position, for instance during turning of the plough girder 4.
Fig. 11 furthermore shows, how the plough may be sidewardly displaced, for instance at the beginning of the ploughing. Finally it shall be mentioned, that the carrying frame 5 at least on level with the driving wheels 18 advantageously may be higher to limit the maximum width of the carrying frame 6 to the statutory 3000 mm. By lifting the whole rear part of the carrying frame 6 it furthermore may be obtained that the rear turning head 16 may be centrally displaced in such a height, that it becomes unneccesary to displace the rear turning head sidewardly, that is that the plough as a whole to a great extent may be simplified, as also the foremost turning head thereby may be stationary and possibly without cardanic suspension. A possible sidewardly displacement of the foremost part of the plough, for instance by driving at slopes, may be contrived in the lift suspension ifself.
Possibly the carrying frame 6 may be avoid, namely if the girder 4 is so heavy that it - besides from carrying all the plough shares - may form the only connection between the foremost turning head of the plough and the reart wheel-supported part of the plough 2.
