Description

The invention relates to agricultural machinery industry and can be used in self-propelled multi-support sprinkler machines of both frontal and circular action when working on difficult trails and slopes.

The purpose of the invention is to increase the soil erosion resistance when working on slopes.

On league. 1 shows a device for leveling a track, placed on a support of a sprinkler, side view; on oig. 2 - then what, plan; on yzhg. 3 - kinematic scheme vcTpoficrea; on

Gig 4 — irrigated field of a multi-support circular irrigation machine and a scheme for the formation of an avalanche hazard irrigation water flow on a slope; in fig. 5 - placement of jumpers on the irrigated field along the ditches of the track gauge of the sprinkler; in fig. 6 - proAil of the track of the circular pivot sprinkler of the Kuban LC and the section of the pemping under its first supporting carriage; in fig. 7 - the same, under the tenth support trolley.

The device for leveling the track contains a bracket 1 which, by bolting, fastens the Y frame 3 of the support carriage, for example

Mnogoporoy sprinkler circular action DNU Frigate. The bracket 1 is provided with a cantilever axis 4, on which an L-shaped beam 5 is freely placed. A spline part of the transverse element 6 of the L-shaped bar 5 accommodates a detachable yoke 7 with drivers 8 and 9 fixedly attached to it. In brackets 10 of the leads 8 and 9 behind crankshafts 11 are fastened by means of bolted joints 12. Spherical disks 13 and 14 are installed on the knee axes 11. The disks 13 and 14 face each other with concave surfaces. The axes 11 in the arms 10 of the leads 8 and are rotatably mounted in the horizontal plane to change the angle of attack as well as change

32 is connected with the free end of the transverse element 6 of the L-shaped beam 5.

The gauging device functions as follows.

When the sprinkler moves under the action of a hydraulic or electric wheel drive 19 support carts

rolls 29 across the bottom of the track 18. Rolled at an acute angle to the direction of movement of the sprinkler the cutting edges of the spherical disks 13 and 14 dump the soil of the ridges from the berms back into the track 18, which was squeezed up along the edges of the berms during the previous passage of the machine or the front wheel 19 frame 3. When you turn the wheel 19 together with him

The depth of the cutting edges of the discs 13-20 is crank 31. With a maximum of 14. On the cantilever axis 4 of the L-shaped beam 5 there is a sleeve 15 with a fixed bracket 16 on its outer surface. The bracket 16 is provided with an adjustable bolt 17. The bolt 25 of part 17 establishes the initial position of the L-shaped beam 5, taking into account the depth of the track 18 behind the support wheels 19 of the frame 3 of the self-propelled cart. Offset back from the cantilever axis 4, the naso bracket 1 is fixed parallel to the axis 20, on which the rod 21 is pivotally mounted. The end of the rod 21 distant from the axis 20 is placed in the vertical slot of the shaped bracket 22, 35 in turn connected to the L-bar stand 23 5. Between the shaped bracket 22, a cylindrical spring 24, a washer 25 and a screwdriver 26 are mounted on the rod 21, and are placed 40 in the holes 27 of the rod 21. This changes the degree of compression of the coils of the spring 24 and 9, respectively., Active amplification through the lever system at the cutting-remote position of the axis of the crank 31 from the free end of the transverse element 6 of the L-shaped beam 5 is flexible coupling 32 tension, and the stop 28 is as close as possible to the rim of the support wheel 19. With further rolling of the support wheel 19, the crank 31 from the outermost dead center approaches the less distant one, releasing the tension of the flexible link 32. During the rotation of the crank 31, another picker 29 approaches the stop 28, and G The brazier beam 5, together with the healthy disks 13 and 14, rises above the track 18. The soil from the inner surface of the disks 13 and 14 is dumped on the bottom of the groove of the track 18 and forms the web 30 (see Fig. 2 and 3). When the L-shaped beam 5 is lifted upward, the distance between the stop 28 and the picker 29 increases, and under the weight of the spherical disks 13 and 14, as well as the compressive force of the spring 24 of the rod 21, the disks 13 and 14 are sharply dropped onto the ridges of the spherical disks 13 and 14.45 The rotation of the crank 31 from the right dead center to the left leads to the re-tensioning of the flexible connection 32. Further, the process of forming the jumpers 30 is repeated.

On the transverse element 6 of the L-shaped beam 5, the stop 28 is fixed in contact with the removable picker 29 of the rim of the support wheel 19 of the self-propelled carriage. Pickers 29 on the surface 50 of the rim of the support wheel 19 of the carriage are placed with an equal angular pitch t ensuring that the track 18 is completely filled with soil to form a jumper 30 of sufficient height to prevent surface runoff. The support wheel 19 of the self-propelled trolley is equipped with a crank 31 fixed on it, which by means of a flexible connection

but the remote position of the axis of the crank 31 from the free end of the transverse element 6 of the L-shaped beam 5 is flexible coupling 32 natu, and the stop 28 is as close as possible to the rim of the support wheel 19. With further rolling of the support wheel 19, the crank 31 from the most distant dead center approaches less distant, releasing the tension of the flexible coupling 32. During the rotation of the crank 31, another picker 29 approaches the stop 28, and the L-shaped beam 5 together with the regular disks 13 and 14 rises above track 18. The soil from the inner surface of the disks 13 and 14 sva pours to the bottom of the ditch of the track 18 and forms the web 30 (see Figs. 2 and 3). When the L-shaped bar 5 is lifted upwards, the distance between the stop 28 and the catcher 29 increases, and under the weight of the spherical disks 13 and 14, as well as the compressive force of the spring 24 of the rod 21, the disks 13 and 14 are sharply dropped onto the ridges.

Prestressing force

the springs 24 on the rod .11 by moving the washer 25, and the wraps 26 by repositioning in the holes 27 achieve a shorter or deeper depth of travel of the cutting edges of the spherical disks 13 and 14.

For translation after leveling the track to full transport position

it is enough to force the human hand to lift the disks 13 and 14 upwards by 500 ... 600 mm. In this case, the L-shaped box 5 will occupy the position shown by the dotted line in FIG. 1, and will pass the dead position relative to the axis 20. In this position, the force of the compressed spring 24 holds in the extremely upper position the shaped bracket 22 and the rack 23 together with the L-shaped balcony 5.

The production of the gauge of the described construction on the alfalfa plant varieties VNIIOZ-16 was irrigated by a multi-support sprinkler machine DMU Frigate with ten support carts. The slope is 0.012. The irrigation rate is 400 m3 / ha. The control is based on the method of eliminating the gauge by leveling it with disk tools.

The results of field studies are presented in Table. 1 and 2. The data of field tests show that the track-leveling device reduces by a factor of 5-3.0 times the drift of the fertile soil layer.
