VEHICLE-MOUNTED EQUIPMENT

Abstract

A vehicle attachment includes a three-position blade mounted on a frame, the wings of the blade being connected Lo one another by a pivot shaft. Elements for attachment to a self-propelled vehicle are situated on one side of the frame, while brackets for connection, via sliders, to the wings of the blade are situated on the other side. Hydraulic cylinders for rotating the wings of the blade are symmetrically fastened to the frame, between the brackets. The rods of the hydraulic cylinders are pivotally connected to the pivot shaft of the blade wings, and the body of each hydraulic cylinder is connected to the frame by a pin. The pivotal connection of the blade to the attachment frame via sliders makes it possible to alter the angle at which the sections of the blade are mounted in a horizontal plane, with the wings of the blade being rotated in synchronism by the movement of the hydraulic cylinders.

[0019] The claimed invention is illustrated by drawings where

[0020] FIG. 1 shows the vehicle-mounted equipment in a top view,

[0021] FIG. 2 in a rear view,

[0022] FIG. 3 in a side view,

[0023] FIG. 4 in a front view.

[0024] Items in the Figures designate the following: 1 shows the frame of the mounted equipment; 2 shows the blade; 3 shows the wings of the blade 2; 4 shows the rotation axis of the wings 3 of the blade 2; 5 shows equipment fastening elements to the automotive vehicle; 6 shows brackets for joining with the wings 3 of the blade 2; 7 shows sliders; 8 shows the guides of the sliders 7; 9 shows the axle of joining the sliders 7 to the frame 1; 10 shows the stops; 11 shows hydraulic cylinders for rotating the wings 3 of the blade 2; 12 shows the pistons of the hydraulic cylinders 11; 13 shows the axis of attachment of the hydraulic cylinders 11 to the frame 1; 14 shows knives of the blade 2.

[0025] The vehicle-mounted equipment comprises a frame 1 carrying a three-position blade 2, the wings 3 of which are connected to each other by a turning axle 4

[0026] The wings 3 of the blade 2 may be made of bent sheet metal and have reinforcements in their rear part, for example as two longitudinal channel-like sections joined by transverse ribs in the longitudinal direction, which is necessary to provide the necessary strength characteristics of the wings 3 of the blade 2.

[0027] The mounting frame 1 is designed for mounting the equipment onto the basic plate of a mini front-end loader and represents the basic supporting structure for all of the components of the mounted equipment.

[0028] On one side, the frame 1 carries members 5 for fastening the same to the automotive vehicle, and on the other side, it carries brackets 6 for linking to the wings 3 of the blade 2 with the help of sliders 7 (FIG. 1).

[0029] Each wing 3 of the blade 2 is attached to the frame 1 by means of four guides 8 of cylindrical shape mounted on the wings 3 of the blade 2 and by means of four sliders 7 pivotally connected to the frame 1 by means of axles 9 (FIGS. 1 and 2).

[0030] The guides 8 contain stops 10 for limiting the motion of sliders 7 upon the same.

[0031] In addition, the stops 10 enable, in the extreme positions of the blade 2, a synchronous position of the wings 3 of the blade 2 about the longitudinal axis of the last.

[0032] The frame carries, between the brackets 6, symmetrically mounted hydraulic cylinders 1 for turning the wings 3 of the blade 2.

[0033] The rods 12 of hydraulic cylinders 11 are pivotally connected to the axle 4 for turning the wings 3 of the blade 2, the cylinder 11 body being pivotally connected to the frame 1 by means of axles 13 (FIGS. 1, 2 and 3).

[0034] The sliders 7 are designed to provide a hinged connection of the blade 2 to the mounting frame 1 and are used for a synchronous turning of the wings 3 of the blade 2 at the motion of the rods 12 of the hydraulic cylinders 11. The connection to the blade 1 is provided by conjugation of the cylindrical embraced surfaces of the guides 8 mounted on the back plane of the blade 2 with cylindrical embraced surfaces of the sliders 7 arranged perpendicular to their turning axles 13.

[0035] The blade 2 comprises, in its bottom part, knives 14 made from sheet material having welded parts with a hard alloy electrode to increase wear resistance of the last (FIG. 4).

[0036] The snowplow is operated as follows

[0037] When carrying out a primary passage in the snow fields, in the piles of building bulk materials, use is made of a sharp-angled arrangement of the wings 3 of the blade 2 (position I, FIG. 1).

[0038] For this purpose, the rods 12 of the hydraulic cylinders 11 are pushed out to the maximum length. The guides move along the sliders 7, the slider 7 turns on an axle 9, expanding the wings 3 of the blade 2 around the axle 4 until getting an acute interior angle between them.

[0039] When preparing the equipment to operate for moving sand or gravel, or snow banks (up to 300 mm), use is made of an expanded horizontal position of the wings 3 of the blade 2 (position II, FIG. 1).

[0040] For this purpose, the rods 12 of the hydraulic cylinders 11 are moved into the housing of the same at a needed value.

[0041] In this case, the guides 8 are moved in the opposite direction with respect to the previous position I, the slider performs a rotation in the direction of the axle of turning the wings 3 of the blade 2 to an expanded horizontal position of the wings 3 of the blade 2.

[0042] The position II provides for the ability to obtain a larger wing surface, with the possibility to reduce the number of runs and the single coverage area of the working surface.

[0043] To prepare operation for pushing out ground/snow, for example, for removing snow from limited areas, or when performing ground planning work, for example, when filling up a trench, use is made of a folded position of the wings 3 of the blade 2 (the position III, FIG. 1).

[0044] In this case, the guides 8 move on the sliders 7 further to the stop 10.

[0045] The sliders 7 turn to the maximum to the turning axle 4 of the wings 3 of the blade 2, unfolding them at an external obtuse angle.

[0046] The position III provides for pushing out volumes of the working material to be displaced with minimal loss of its volume, which eliminates the need to return the vehicle for repeating the operation of removing materials spilled when pushing out.

[0047] At any provision of the wings 3 of the blade 2, the load from the working ground is distributed from the knife 14 located on the blade 2 to the guides 8, and from the guides 8 to the sliders 7 and further onto the frame 1 via the axles 9 for turning the sliders 7.

[0048] The advantage of the claimed invention is the ability to change the angle of installing the blade elements in the horizontal plane, due to the drive for rotating the same from the sliders providing for a hinge link of the blade with the mounting frame with a synchronous turn of the blade wings thanks to the motion of the hydraulic cylinder rods, which improves strength, maneuverability of the constriction and a compact design of the last, together with the extension of functional possibilities of the vehicle-mounted equipment.
