    1471317 Agricultural implement P W ZWEEGERS 12 June 1974 [14 June 1973] 26070/74 Headings A1F and A1P A crop working implement having two or more sections pivoted together at a point 17 near the working elements 35-38 comprises beams 7, 8, the beam 7 being carried by a vertical support 6 and having a pivot 13 at one end to which is coupled an arm 15. The pivot 17 joins arm 15 to a further arm 18 which is rigidly connected to the beam 8. An upstanding arm 19 is rigidly connected to the arm 15 and is pivotally connected to a rod 21 the other end of which carries a sliding pin 22. An hydraulic ram 26 is carried on beam 7 and its rod 28 is pivotally connected to the arm 19. The ram 26 controls the pivoting of the beam 8 and corresponding working elements 35-38 to suit uneven ground and can also raise it to a transport position. A latch 30 controls the extent of movement of the piston rod 28. The two working elements of each pair are rotatably driven in directions towards one another at the front of the implement, which is adapted for connection to the front of a tractor by a telescopically extendible 3-point linkage which allows the beams some give when an obstacle is met. A shear-off safety device is provided on beam 7.

    The invention relates to agricultural machinery, in particular to machines for harvesting agricultural crops.
    An agricultural implement is known, which contains a frontal transverse horizontal bar, mounted by means of a linkage with a lift hydraulic cylinder and having side sections centrally and pivotally connected to it rotatable in the transverse vertical plane, the ijoBopoTa hydraulic cylinders of the lateral sections fixed to the sections and located underneath the sections and below them are rotary hinges attached to the sections and underneath them. working bodies with cutting edges and conical flanges, under which are placed the supports 13 The disadvantage of the known tool is that Natural axial movements of the sections of the frame beam change the distance between the agriculturally fascinating edges of the adjacent operating elements, since these edges are located at a distance and under the frame beam. As a result, when, for example, a field with a wave-like relief is processed, the edges of the adjacent operating elements may undesirably touch each other, which will result in the knives of the adjacent rotary elements of the mower cutting device hitting one another and The connection between adjacent working bodies can momentarily increase to such a size that unprocessed strips will remain on the field.
    The purpose of the invention is to improve the quality of cleaning by ensuring a constant distance between the cutting edges of the working bodies.
    This goal is achieved by the fact that in the device the boom sections have brackets that are connected to the central section by means of hinges at an angle to the arms of the levers, with the tops of the corners formed by the brackets and levers pointing down, and the hinges of their joints are located at the level of rotary workers organs.
    The hinge joints of brackets and levers are placed in the mensdu zone by two adjacent conical flanges.
    The side sections have limiting their rotation in the working position.
    The tool is equipped with a safety device against collision with an obstacle.
    FIG. 1 shows a front view agricultural tool containing a three-section front-mounted rotary mower (one position (working) shown
    solid lines, and the other two possible positions - dotted lines); in fig. 2 - the same, the possible position of the rotational mowing of the front linkage; in fig. 3 5 rotary front-mount mower, top view (possible positions are indicated by dotted lines); in fig. 4 - the same, side view (a possible position is shown by dashed lines).
    The front of tractor 1 is associated with an agricultural tool for mowing plants. This gun contains a three-point lift,
    5 with an adjustable upper arm
    2 and two lower arms 3 and 4, moved up and down by hydraulic cylinders 5. The free ends of the levers 2-4 carry the supporting elements b in a vertical position. Bottom levers
    3 and 4 are a telescopic design that is slightly extended as shown by dotted lines. The force at which the expansion takes place can be determined by a device of instantaneous action between two telescopic parts, for example, in the form of a spring-loaded ball.
    - The vertical support element 6 carries the central section 7 of the frame beam of a three-section front-mount rotary mower. The central section is attached to the transversely adjacent side sections 8 and 9 of the frame beam and is connected to the support b by lower connecting levers 10 and 11 and the upper rod of the double connection 12 extending obliquely upwards from
    0 section 7 of the frame in the direction of the upper arm 2. Each end of the central section 7 of the frame bar carries a hinge 13 or 14, to which is attached a lever 15 or 16 extending obliquely downwards and outwards from the adjacent end of the beam section 7.
    In the following, only the left half of FIG. 1 and 2, since the parts are right and left
    Qs from the longitudinal center plane are similar.
    The lower end of the lever 15 extending downwards carries the hinge 17 and with this hinge a bracket 18 is connected, extending obliquely downward from the adjacent end of the left side section 8 of the frame beam. Bracket 18 is rigidly connected to section 8 of the frame beam. In the normal position of the cannon, the three sections 7-9 of the frame bar are installed in one line. However, they can move vertically with respect to each other because of their articulated
    5 compounds. If desired, this movement may be caused by the operator through the device described below.
    The vertical part 19 is rigidly connected to the roller 15 and the upper end of the part 19 is connected through a hinge 20 to the rod 21, the other end of which is carried by the finger 22, which slides in the groove 23 of the vertical double flange 24 mounted on the upper section of the frame beam 8 its outer end.
    The central part of the central section 7 of the frame beam carries a vertical double flange 25, with which yiapHHpHQ are connected by two hydrocrafts; Lindra 26 and 27. The connecting rod 28 of the hydraulic cylinder 26 is pivotally connected to an intermediate point 29 of the vertical part 19, which is also a double structure, so that The head of the connecting rod 28 is located between the two sides of the double part 19. The head of the connecting rod 28 is connected to the two sides of the double part 19 by the pin 29.
    The side of the cylinder of the hydraulic cylinder 26, itself close to the head of the connecting rod 28, carries the lock 30, which is fixed for. upward swiveling remegpeni. (In Fig. 1, the retainer 30 is shown in the upper position, and in Fig. 2 - in the lower position). The head of the latch 30 in the lower position is located on the line of movement of the head of the vaatuna 28, so that the inward movement of the connecting rod 28 from the full extension position is limited to a short section. The length of the retainer 30 is selected with respect to the position of the full extension of the connecting rod 28 such that the inward movement of the connecting rod 28 in the lower position of the retainer 30 allows the work elements 31 and 32 mounted on the frame 8 section 8 to rise from the ground.
    The device contains, besides working elements 31 and 32, working elements 33 and 34 with annular flanges 35-38 and cutting devices with saucer-shaped ground supports 39-42.
    The working elements have drive shafts 43 and 44 connected to shafts 45-47,
    In this embodiment, the operating elements 31 and 32, hinged on the side sections of the 8. Frame beam, the elements 33 and 34, hung on the intermediate central section 7 of the frame beam, and elements (F1, 1 and 2 are not shown). hinged on the frame beam section 9, contain rotary working bodies (drums), to the lower sides of which conical stakes are rigidly attached target flanges 35-38, respectively, cutting, apparatuses are distributed around each of the annular flanges
     and free rotations, saucer-shaped ground supports 39-42, respectively, are mounted under flanges 35-38. Sequential work items 31-34, etc. synchronously, but in the opposite manner, driven into action.
    0 the effect of a gear such
    that the cutting blades of the cutting apparatus attached to the flanges can work together without the danger of collisions of the cutting apparatus,
    5 The performing elements of the pair 31 and 32 rotate towards each other on the front of the gun, which also applies to the elements of the pair 33 and 34 and to the elements of the third section (not shown J.) This means that the two performing elements , priklyayuschie to the connection of two sections 7 and 8 or 7 and 9 of the frame beam, rotating
    5 are opposite to the other on the front of the implement and, therefore, move the crop in opposite directions, so that the downwardly directed levers 15 and the brackets 18 can extend down to the zone in which they do not interfere with the work performed by the implement. The hinge 17 of the levers 15 and the brackets 18 is located between adjacent
    5 with flanges 36 and 37 and slightly higher than the level of the cutting disk of the cutting apparatuses attached to these flanges. This means that when the weapon moves on the ground, two
    0 side sections 8 and 9 of the frame beam and the elements performing the work ,. carried by these sections can adapt to the uneven ground surface and a possible obstacle to this
    5 field without subsequent vertical rotational movements of the other two. Sections 8 and 9 of the frame beam, causing a significant change in the distance between the exciting agricultural culture of the parties
    performance of the elements, number 1. tipping to the inner sides of the sections of the frame beam.
    Combined vertical rotary movements of the sections of the frame beam can be caused by the sliding of the ground supports 39-42 of the elements performing the work over an uneven field, but can also be caused by the operator through the action of hydraulic cylinders 26 and 27. In both cases, the vertical movement of the side sections 8 and 9 the frame beam is limited by the length of the groove 23 in the 5th vertical flange (and the corresponding parts on the other side of the gun) and the limited movement of the connecting rod 28 between its maximum extended position and its retraction Azad position at the lower position of the retainer 30. These two kraLnie position shown in FIG. 1 (the lower position is shown by the dotted line) and in FIG. 2 respectively. However, if the latch 30 is moved to the upper position (Fig. Ij, Katun 28 can be completely retracted into the hydraulic cylinder 26 so as to raise the side section 8 of the frame beam and the working elements connected to the section almost to the vertical position, shown in dotted lines (upper position) in Fig. 1.
    The hydraulic cylinders 26 and 27 can be so connected with the hydraulic power cylinders 5 of the three-point lifting device 2-4, that after reaching the upper extreme position of the sections 8 and 9 of the frame beam (both in the upper and lower positions of the lock 30), the hydraulic power cylinders 5 will start to operate when the pressure in the hydraulic system increases, so that these power hydraulic cylinders raise the central section of the frame beam and the working elements carried by this section.
    The operating elements are driven by two synchronously rotating shafts 43 and 44 of the device for tapping the power from the tractor's engine to the implement at the front of the tractor. These shafts are connected by means of circumferential shafts and universal hinges with inlets 45 and 46 extending from the central section 7 of the frame beam. Drive shaft (not shown extends longitudinally in the frame beam section and contains a safety shut-off device in the central part of the timber section 7. This device, for example, contains a clutch with a gripper that are intended to be turned off at a pre-set overload. Shafts 45 and 46 are connected a gear drive with a longitudinal drive shaft (not shown), the shafts of the two perform the work of the elements 33 and 34 are also connected to the longitudinal shaft of the conical gear engagement, but so that they are in the opposite direction, as shown by the arrow in Fig. 3. The direction of movement of the weapon is shown in Fig. 3 by arrow A ,. Thus, two
    Elemench 33 and 34 rotate towards each other on the front of the gun.
    The longitudinal drive shaft in the sections of the frame shaft protrudes on both sides of the section 7 of the beam and is joined together. with universal joints with corresponding longitudinal. drive shafts extending and projecting from sections 8 and 9 of the frame beam.
    The operating elements 31 and 32 are connected to the shaft 47 of the section 8 of the frame beam (Fig. 1) in a manner similar to the connection of the
    15 the operation of the elements 33 and 34 with the longitudinal shaft of the section 7 of the frame beam. Universal hinges, connecting the longitudinal drive shaft in the section 7 of the frame beam with the longitudinal drive shafts in sections 8 and 9 of the frame beam, allow such an angular movement between the shafts that they do not increase the extreme segments of the frame beam to the highest position shown for section 8 by the dashed line in FIG. 1. I
    Sections 7-9 of the frame timber are located on the same line and mostly horizontally in a normal position. In the described embodiment, they extend at right angles to the direction of movement of the gun, but it is also possible that sections 7–9 of the frame beam extend into normal
    5 position tilted backwards along
    in relation to the direction of travel. Instead of the elements of the rotational section 7-9 of the frame beam can carry other exciting land
    Q or agricultural work items. Each individual unit performing the work may have its own ground support, but this is not necessary. Work items may
     also be held at a distance above the ground by a hydraulic device, or the implement may have ground wheels placed between the elements that perform the work. The edges of the work of their elements can be rotated in accordance with the discs placed in a plane mainly parallel to the ground, but they can also be rotated in planes,
    5 which are located at an angle to the ground, and they can also coBejsuaTb other movements. The frame bar of the cannon can be made up of two, three or more sections. Not necessary
    0 in that the sections of the frame beam are mounted on one straight line in the normal position. The instrument must be designed so that the sections of the frame beam are placed at the angle of the angle to the friend in a normal
    either in the horizontal plane or in the vertical, the implement is not necessarily a front mounted implement, it does not necessarily have to be mounted on a tractor, and it is not necessary that the implement be connected to a three-point lifting device, although the described is the preferred option. Also, the described lifting devices for the side sections of the frame beam are optional and have to be replaced, for example, by a pull rod, although the described lifting device has many advantages as compared to a simple pull cable.
    Lower levers 3 and. 4 three-point telescopic lifting device. This is of paramount importance for a cannon suspended from the front of the tractor, since the usual decoupling mechanism cannot be used for such a cannon to prevent damage from hitting the obstacle. The extendable levers 3 and 4 g. Replace such a disengagement mechanism. When one of
    the outermost performing elements fall onto the obstacle, the whole cannon swings around the axis defined by the line through the abrupt end of the upper arm 2 and the outer end of the lever closest to the obstacle (lever 3 in Fig. 3). The combination of these levers with the tool allows, within certain limits, the movement of it from all directions, so that part of the tool, having bumped into the obstacle, can be tilted back near the axis, and the opposite part of the tool, in front. When swinging the NEAR AXLE, the lower part performed the work of the elements also moving forward with respect to their normal position (Fig. 4, so that the position of the elements and especially their ground supports became more suitable for sliding on the obstacle. After passing an obstacle to a weapon under its own weight is returned to its normal position and OAHoSpefieHHO moves the lever 4 to its normal retracted position.
