Description

FIG. 1 shows a front view of a device for digging ditches; in fig. 2 - side view of the same device; in fig. 3 - its internal view; in fig. 4 is a side view of an apparatus for cleaning snow from railway tracks, and FIG. 5 - front view of the same device.

The device consists of two disks, a plate-like form, folded with wide sides and fastened with internal partitions, and the device for digging ditches (Fig. 1-31) may have a different shape of the disks: in the form of an ellipse, stretched or compressed, in the form of an oval or ball , depending on the desired ditch profiles. In Fig. 2, discs A, A are shown, folded outwardly and connected inside by curved partitions H, H converging in the center of the device and diverging to the circumference.

C1 is fixed on the axis I / I, with which they are driven into rotation by the engine. According to the figure of curved inner partitions H, the surfaces of the disks are provided with slots C, C extending from the center to the periphery of the disks, above which are attached the knives K, K, the blades of which protrude above the surfaces of the disks (Fig. 1-3). In the spaces between the knives, along the circumference of the discs, there are slots / 7 (Fig. 1), which serve to eject the knife-cut through them ;; soil, thanks to the rotation of the device, telling the soil centrifugal force. On the lateral parts of the discs, between the cuts and knives, a series of thin plates G protruding above the blades of the knife are fastened, and, moreover, around the circumference of the folded disks, in place of their contact, a thin ring P extending beyond the blades of the knives is attached. with it

the edge of the ring can be provided with teeth; Both the ring and the plates are intended to protect the knives from hitting the stones in the soil, as in such cases, pr /: meeting stones, the device y, Jap etc. with the protruding parts mentioned above and automatically exiting DP1 from. I

The proposed device to dig a ditch is strengthened in front of a tractor or an appropriate one; forward movement of the surf; ra, i-aiK, that the axis of the device is located; It is driven directly to the progressive movement and is rotated by a separate engine or oi- the same engine by means of a gear transmission. For the drive to work, it’s rotating around the M axis and at the same time having-1 forward movement, 11O) cutting into the soil to the required depth, while the device cuts i the ground with knives, which C is driven into rotation by the partitions H, H and, due to the centrifugal force, is thrown through the slits I.

A snow removal device for railway tracks is located in front of the carriage, in a plane perpendicular to the railway track, and is mounted on the carriage protruding from the carriage | B axis with rear deaf disk A (FIG. 5),; connected to the front disc A along with U1 B, and with the walls of H (Fig. 4), j extending from the center along diverging lines; by curves, along with piers, on the front disc i are also made by curved I-linear cuts, over which knives K of the same shape, protruding with blades beyond the disc surface (Fig. 4 and 5), are strengthened. C c S is provided with a slot, ending with a socket G, through which, when the device rotates, due to centrifugal force, snow is thrown out of the device in the direction to which the socket G is passed, which does not participate in circular motion, discs being bonded I with a platform. The described device should also be used for digging ditches when placing it on the tractor so that the axis of the instrument runs parallel to the ditch.

SUBJECT PLT T: AND T L.

Claims (3)

I. A device for digging ditches or cleaning snow from railways; the pathways, characterized by the use of two convex plates A, A, fastened from the inside between them by curvilinear lines, going from the center to the circumference (Fig. 2, 3, 4) with walls of H, N mounted on the M-axis, fitted along the walls of the cutouts with cuts C, covered outside with knives of the appropriate form K, C and having circumferentially, in L1estah between the walls, cuts P, P for the departure of loose ground or snow, while rotating the disk ( Fig. 1, 2, 3), in which the device for digging ditches the axis of the disk lies under the right an angle to the direction of translational motion, and in a snowplow in the direction of translational motion, and is driven into firing by a separate engine, or is in adhesion of the combustors to the engine of translational movement. . 2. Modification of the device according to claim 1, characterized in that the disk is provided with a steel ring P, P protruding beyond its circumference with teeth or plates G, T (Fig. 1-2) projecting from the surface of the plates over the blades of the knives K, K ..., in order to protect the knives of the device from stones. 3. Modification of the device according to claim 1. intended, mainly, for clearing railway tracks from snow, depending on the fact that the disk plates are located wider on the walls of the I, N ..., and the gap between the plates is fixed stationary, during operation, with a shield or casing B with a socket G intended for the departure of snow or; land, with what knives I, I ... equipped only with the front plate of the disk (Fig. 4, 5).
