    An earth moving machine having an improved mounting for a scraping blade attached thereto. The scraping blade of the machine herein disclosed is capable of undergoing independent or simultaneous rotational movement about three perpendicular axes and applying high forces to material to be moved. Movement about two of these axes is controlled by two separate pairs of hydraulic cylinders. A hydraulic actuator effects movement of the blade about a third axis and acts to transmit a part of the force applied to the blade during operation to the frame of the machine.

    (54 BULLDOZER
    J. :.
    Isofetenation refers to earthmoving machines and can be used for the development and propelling of soil.
    Known bulldozer, including base machine, bravery frame, hydraulic cylinder rotations of the frame relative to the axis of the hinges attaching it to the base machine, hydraulic cylinders of the blade turning into a dump and hydraulic cylinder of the transverse skew of the blade, connecting the frame to the upper part of the blade through the intermediate swinging L
    The disadvantage of this bulldozer is the complexity of the design of the connection of the upper part given to the frame.
    The closest to the base unit is a bulldozer that includes a base machine with a pushing frame hinged on it, a blade connected to the pushing frame by means of a central universal joint and a hydraulic motor mounted on the supporting element of the pushing frame and providing a cross-section skew of the blade, mcdro, that provides the transverse skew of the blade, mcdro, and the hydraulic shaft, pivoting frame, O1
    relative to the axis of the hinges attaching it to the base machine and the hydraulic cylinder of the blade rotation in plan 23.
    A disadvantage of the known bulldozer 5 is that the support ne takes longitudinal forces from the blade through a hydraulic engine, made in the form of a conventional hydraulic cylinder.
    Uerib of the invention is an increase in the strength of the structure due to the transfer of a part of the longitudinal force from the Otala 1 to the central part of the frame through the supporting element.
    This goal is achieved by

    15 in the bulldozer including the base machine with the pusher frame hinged on it, an ax connected to the pusher frame by means of a central universal joint and ensured 20 times the transverse bias of the hydrodvE dump of bodies mounted on the supporting element of the pusher frame, turn cylinders. the hinges of the fastening. its to the base machine and the gyaroshigand of the blade rotation in the plan; surfaces inside which the piston is located with a transverse channel in the central part and a vertical finger installed in it by means of a spherical hinge located in the longitudinal slots of the cylinder, and in the area of the cylinder ends there are holes for supplying the working fluid under pressure; and end lugs fixed on the blade, and with the help of a vertical finger on the supporting element of the pushing frame .. In addition, in order to change the angle of the blade, the latter is equipped with lugs having p d finger holes for fastening lugs each tsiyind pa, and the supporting element is also provided with eyelets adjacent holes ver Calne finger hydraulic motor. FIG. 1 shows the proposed bulldozer, side view; in fig. 2 - the same plan view with an internal pushing frame; in fig. 3 - hydraulic engine, transverse skew of the blade; Fig. 4 is a hydraulic control circuit of the working equipment of the bulldozer; in fig. 5 blade widths cut; Fig. 6 is a version of a bulldozer with an outer circumferential pushing frame, a plan view, the Butt-dozer includes a base machine I, a pushing frame. 2 with hinges 3 fasteners, a central universal joint 4 and a supporting element 5 rigidly fixed in the central part of frame 2, a blade 6 mounted on frame 2 by means of Hinge 4 and hydraulic motor 7 connected to the eyes 8 of the blade 9 with fingers and vertical finger H and , with lugs 11 of the support element 5. The rotation of the frame 2 relative to the axis of the hinges 3 is carried out with hydraulic cylinders 12, which ensures the raising and lowering of the blade. The blade rotates in plan with hydraulic cylinders 13. The lateral tilt of the blade performs hydraulic motor 7, which contains a blind cylinder 14 made of a tubular body 15 and end caps 16, rigidly fixed to the body 15 with bolts 17. CYLINDER 14 has end lugs 18 and longitudinal slots 19; Inside piston 14 there is a piston 20 with a transverse channel 21 and a vertical arm U, installed by means of a spherical hinge 22 in it. In the area of the ends of the cylinder 14 there are holes 23 for supplying the working fluid under pressure m. To eliminate leaks, the hydraulic engine 7 is equipped with sealing rings 24. The bulldozer hydraulic system includes tank 25, filters 26, hydraulic pump 27, hydraulic steering valves 28 to 30 controlling hydraulic motor 7 and hydraulic cylinders 12 and 13. The hydraulic valves are fitted with hydraulic check valves 31 and a non-return valve 32. The stiffening blade 6 is made of a box section with a front sheet 33, a rear wall 34 and a stiffener 35 located along the entire length of the blade and having a V-shaped shape. To change the blade 6 blade in the lugs 8 and II there are a series of holes 36 and 37 for manually replacing the fingers 9 and Y. The buoydozer works as follows. The dumping of the blade for raising the soil is lifted using hydraulic cylinders 12. To move the soil to one side or the other t3 hydraulic cylinders rotate the blade 6 relative to the vertical axis passing through the axis of the central universal joint 4 and the spherical hinge 22. When the dump Kpaswf is in operation for cutting ditches, ditches or for developing solid ground, pop lateral tilt of the blade. For this, the piston 20 is set under the pressure of the working fluid to the extreme left or th position, while the right or left edge of the blade is lowered and its development is carried out with a sharp end. The longitudinal forces arising on the dump when excavating are partly perceived through the hydraulic motor 7 by the supporting element 5 of the pushing frame 2, which unloads the hydraulic cylinders 13, which can be made of a smaller diameter, and, in addition, increases the reliability of the whole structure. Claim 1, a bulldozer, including a base machine with a pushing frame hinged on it, a blade connected to the pushing frame with central universal hinge and providing a transverse skew of the hydraulic engine 5g mounted on the supporting element of the pushing frame, the front hinge bar on the front of the front hinge branch of the front hinge bracket. to the base machine and hydraulic cylinders turning the blade in, characterized in that, in order to increase the design efficiency by transferring part of the longitudinal arms force from the blade to the central part of the pushing frame through the supporting element. The hydraulic motor is made in a vvde deaf cylinder with thorium lugs and longitudinal protrusions on the lateral surface, inside which there is a piston with a transverse channel in the central part and a vertical pin installed in it through a spherical hinge, pad placed in the longitudinal slots of the cylinder, and in the area of the cylinder ends the holes for supplying the pressure fluid with the working fluid are filled, while the cylinder is fixed to the blade by means of fingers and end lugs, and with a vertical finger on the support element 2, Bulldozer according to claim I, characterized in that, for the purpose of tilting the blade, the latter is provided with eyelets, kilometers of a number of holes for the finger of each cylinder eyelet, and the supporting element is also provided with eyelets a series of holes for the vertical finger of the hydraulic engine.
