Definitions

  • the present invention re fers to an agricultural machine comprising partly at least three packer sections, such as rollers, wheels or similar, which are supported by beams, which are jointed relative to each other around axles mainly horizontal in the driving direction, where in the working position the side packer sections are so assembled that they are disposed in front of or behind the side beams, and the centre packer section is so assembled that it is disposed resp. behind or in front of the centre beam, viewed in the driving direction, partly three tool sections, which are comprised of at least one row of soil cultivating tools, such as coulters, discs, cultivator tines or similar, and which in the working position are assembled resp.
  • packer sections such as rollers, wheels or similar
  • a s owing device which is adapted to met er out granules, such as seed, fertiliser or similar, via metering apparatus to the mentioned tools, where in in the working position the mentioned beams are adapted to be rotated so that the packer sections of the centre section roll on the soil and the packer sections of the side sections together with the outer tool sections are rotated upwards to a transport position above the mentioned side beams.
  • Agricultural mach ines of the initially described type normally have a seed con tainer that is carried by the framework of the agricultural machine. From the seed container , seed is metered out to tools arranged at the machine, which first slice or tear a seed furrow in the soil, where the seed is placed at a predetermined depth. In m any cases it is important that this depth be kept as constant as possible during the sowing process.
  • the use of an agricultural machine according to the above can result in the sowing depth not being kept constant and regulation of the sowing depth, so as to keep it constant, can be expensive and complicated.
  • the objective of the present invention is to achieve a device at an agricultural machine of the initially described type, which device solve s the abovementioned problems and in addition is simple and reliable with respect to both construction and function.
  • the mentioned sowing device is provided with transport a pparatus, such as wheels or caterpill ar tracks, and a container for granules, which is t owed by means of a tow apparatus jointed Iy assembled at the machine and which is connected with the mentioned metering apparatus, and that in the transport position the mentioned side beams with associated side packer sections and outer tool sections are adapted to b e rotated rearwards and inwards towards the sowing device.
  • the agricultural machine according to the invention is used for both soil cultivation and sowing in a more reliable way. It is simple in its function especially as regards the transition from working position to transport position and vice versa. I t is advantageous that the load from the seed in the seed container does not act directly on the framework of the machine. A wagon trailed behind the machine confers the advantage that the weight of the seed does not affect the performance of the machine w ith respect to sowing depth. Load directly on the framework gives rise to complicated regulation of the sections of the machine in relation to each other in those cases where an essentially constant sowing depth is desired. In addition, there is no need fo r compensation for change d loading of the centre section with time as the seed is gradually emptied out of the container during s owing.
  • a further advantage of the agricultural machine according to the invention is that the side sections are folded rearwards towards the sowing device in the transport position. This means that the side sections can be made long, i.e. the machine can be given a wide form. During folding of the side sections to a vertical position there are height limitations for driving on public roads. These regulations may be ordained by law, but can also be imposed by low bridges, etc.
  • Fig. 1 shows a perspective diagram viewed from the front of an agricultural machine according to the invention, where for the sake of clarity a plurality of seed hoses from a distribution device to sowing tools have been removed.
  • Figs. 2 and 3 show respecti vely a side view and a plane view of the agricultural machine according to the invention in working position, where for the sake of clarity a plurality of seed hoses from a distribution device to sowing tools have been removed.
  • Figs. 4 and 5 show respecti vely a side view and a plane view of the agricultural machine according to the invention in transport position, where for the sake of clarity a plurality of seed hoses from a distribut ion device to the sowing tools have been removed.

  • the agricultural machine in working position shown in Figs. 1 - 3 comprises a towbar 2, a frame 3 connected with the t owbar 2, a fore soil tillage assembly 4 connected with the frame 3, a rear soil cultivating assembly 5 connected with the frame 3 and a sowing device 6 linked with the frame 3.
  • the towbar 2 has a coupling 7 so that it can be towed by a not shown tractor.
  • the towbar 2 is rigidly connected with the frame 3 and comprises two frame parts 8 and 9 extending obliquely rearwards, wh ich in their turn are fastened at resp. arms 10 and 11 , between which a beam 12 is fastened.
  • a cent re beam 13 is jointedly connected by means of a mainly horizontal rotation ax Ie 14.
  • An adjustment apparatus 15 preferably a hydraulic cylinder aggregate, is arranged between the frame 3 and the centre beam 13, and is adapted when activated to rotate the centre beam in relation to the frame 3 around the ax Ie 14.
  • Two side beams 16 and 17 are in working position according to Figs. 1 - 3 jointedly connected around mainly horizontal rotation axles 18 and 19 adjoining each end of the centre beam 13.
  • a centre roller package 20 is freely journalled in bearings on arms 21 and 22, which are fastened at the centre beam 13.
  • a first side roller package 23 is freely journalled in bearings on arms 24 and 25, which are fastened at one side beam 16.
  • a second side roller pac kage 26 is freely journalled in bearings on arms 27 and 28, which are fastened at the other side beam 17.
  • the roller package s constitute the rear soil cultivating assembly 5 and compact the soil and fill in the sowing furrows created by the fore soil cultivating assembly 4.
  • the roller packages 20, 23 and 26 have the task of controlling the sowing depth by means of the fore soil cultivating assembly 4, described more closely below.
  • the fore soil cultivating assembly 4 comprises three tool sections 29, 30 and 31, of which the side sections 29 and 31 are rigidly connected at the side beams 16 and 17 via arms 32, 33, 34 and 35 and of which the centre section 30 is assembled directly at the frame 3.
  • Tools 36 such as freely rotating discs, freely r otating seed coulters, cultivator tines or similar, are here arranged in two rows on the fore soil cultivating assembly 4. The number of rows can depend on soil type and how dens ely one wishes to place the seed furrows.
  • Crossbeams 37 and 38 are assembled o n the arms 32 - 35 and their ends facing towards the centre of the machine are provided with a coupling part 39 in the form of an eye, which on transition to the working position is adapted to receive a p eg 40, which is mounted on the side arms 10 and 11 of the frame 3.
  • An adjustment apparatus 41 preferably a hydraulic cylinder, is coupled between each side beam 16 and 17 so as to rotate the side beams and fix them in the transport position, which will be described more closely below.
  • the sowing device 6 is towed behind the rear soil cultivating assembly 5 or more specifically behind and essentially at the centre of the centre roller package 20 and comprises a container 42 for seed, fertiliser or similar granules. On the rear side of the container 42 is fastened a mainly horizontal bar 43, which bar protrudes out on each side of the container 42 and forms flanges 44.
  • the sowing device 6 also has a rigidly attached and extending forwards in the driving direction drawbar 45, which at its forward end has a coupling in the form of two jointedly co -connected and interlocking annular coupling fittings 46 and 47, which are fastened at the centre beam 13 and the drawbar 45 resp. and which are displaced approx.
  • the sowing device 6 also has two wheels 48 and 49, which are journalled in bearings on both sides of the container 42. From the container 42 extends forwards a fixed pipe 50 for transport of seed, ferti User or similar granules. One end of the pipe 50 is connected within the container to a not shown dosing and metering device for granules. The other end of the pipe 50 outside the container is connected with a flexible tube 51 , which at its other end is c onnected via a further fixed pipe 52 to a distribution device 53 for granules.
  • Figs. 4 - 6 the agricultural machine according to the invention is shown in the transport position.
  • the centre beam 13 rotates by the centre roller package 20 rolling on the ground and simult aneously rotating the side beams 16 and 17 so that the side roller packages 23 and 26 are rotated upwards to a position above the side beams 16 and 17 and so that the outer tool sections 29 and 31 of the fore soil cultivation assembly 4 assembled at the s ide roller packages 23 and 26 adopt a position above the side roller packages 23 and 26.
  • the centre tool section 30, which is assembled at the frame 3 does not move in this transition between working and transport position.
  • the s ide beams 16 and 17 can be rotated around the axles 18 and 19 to a position where they come to abut against the sides 42 of the container, and can thereby through a slight activation of the cylinder aggregate 15 be brought to abut against the protruding flanges 44 of the bar 43, whi ch is best depicted in Fig. 6.
  • T he cylinder 15 is thereafter activated further, which means that it influences against the centre beam 13 and causes it to be rotated somewhat further so that both the centre roller package 20 and the tool section 30 in the centre are elevated and brought out of contact with the soil.
  • This elevating of the centre roller package 20 and the tool section 30 can alternatively be accomplished by means of the tractor power take -off.
  • the agricultural machine 1 can therein b e towed by the tractor , where the only wheels are those wheels 48 and 49 assembled at the sowing device 6.
  • double wheel pairs can be arranged, the main feature being that they are only journalled in bearings on the towed sowing device 6.
  • Th e agricultural machine 1 must thus have been driven straight forwards a short distance before the transition manoeuvre to the transport position can be initiated, since it is important that the drawbar 45 is disposed insofar as possible parallel with the d riving direction so as thereby to automatically bring about interlocking between the recess 57 of the locking plate 56 and the drawbar 45. Furthermore, the recess 57 is somewhat widened at its entry orifice so that the drawbar 45 can be guided into the rec ess 57.
  • One end of the hydraulic cylinder 41 is fastened at an arm 58, which is fastened at and protrudes from one side beam 16, and its other end is fastened at a similarly symmetrically attached arm 59 at the other side beam 17.
  • the rear bar 43 with its flanges 44 protruding on both sides of the container 6 could be omitted when the power take -off is used to elevate the machine so that the centre roller package 20 and the tool section 30 in the middle come out of conta ct with the soil.
  • the flanges mean a removal of load from both side beams 16 and 17 with their associated side roller packages 23 and 26 resp. and side tool sections 29 and 31 resp. This is also the case due to the arrangement of the cylinder 41, w hich influences the side beams with tools attached thereon against the sides 42 of the container, whereby a locking at the sides of the container 43 of the sowing device 6 is in many cases not necessary.
  • the fore tool section 30 is assembled on the centre beam 13.
  • the tools are therein so arranged that they are a ssembled in groups, which, when the centre beam 13 is rotated from the working position towards the transpor t position, are displaced upwards between and outside the beams 8 and 9 of the frame 3.
  • a single beam can replace all or part of the beams 8 and 9.
  • the rotation from the working position to the transport position is achieved through the beam being rotated in the opposite direction and the packer sections being arranged in front of the tool sections in the driving direction.
  • the centre roller is arranged in front of the centre beam and the side rollers are arranged behind the side beams.
  • Rotation into the transport position is achieved as in the embodiment illustrated preferably rearwards towards the sowing device.
  • This embodiment can be suitable in such cases where one wishes to pack/roll the soil before sowing.
  • the sowing furrows are closed in this case by means of wheels freely journalled in bearings mounted behind the tool sections. These wheels can also be brought to be rotate d upwards in transport so that the wheels of the sowing device comprise the only transport wheels in this case too.
  • rows of wheels or other known assemblies for packing soil can be arranged on the beams 13, 23 and 36 to pack the soil a nd close the sowing furrows created.
  • those wheels that are arranged on the centre beam can naturally also be used during transport of the agricultural machine together with the wheels of the sowing device.
  • the hydraulic cylinder aggregates shown in the drawings can be comprised of any known adjustment apparatus or power apparatus whatsoever. Instead of the wheels 48 and 49 caterpillar tracks can be arranged on the sowing device 6.
