Description

one

The invention relates to the excavation and movement of soil by a milling tool and can be used to dig a square shape in limited areas for working in summer and winter.

A digging device is known, which contains a pivoting boom with a working body, a body pivotally attached to the boom and made of two bar chains connected to one another with an undercutter 1,

The closest in technical essence to the invention is a trencher, which includes a working body in the form of two vertical bars with a horizontal cutter placed between them for producing vertical and horizontal cuts in the ground, mounted on a self-propelled chassis, and a lifting and lowering bucket for supporting and excavating the ground block . The lifting bucket is mounted for horizontal movement on a boom pivotally connected to a pivoting device mounted on a self-propelled chassis, moreover, to remove the block of soil from the trench, the boom is equipped with a lifting rope 2.

The disadvantage of the device is the inexpediency of its use when digging short meters (up to two meters) in connection with the need for preliminary preparation of the entry trench

} 0 length up to 1.5 m and depth to the design mark, which requires the use of heavy manual labor when using the device in winter conditions.

The purpose of the invention is to increase productivity and simplify the design.

This goal is achieved by the fact that the digging device m, including the base load gauge, the frame with the working body

20 in the form of two parallel vertically installed bars connected in the lower part by a shaft with a horizontal cutter, mechanisms for raising and lowering the tool and soil, the mechanism for feeding the tool to the bottom is equipped with a horizontal frame with support wheels and a movable carriage on which the frame is mounted body and mechanisms of its lifting, lowering and feeding to the bottom, and the mechanism of lifting the soil is made in the form of a drum with flexible elements mounted on a horizontal frame with the possibility of vertical movement In this case, the free ends of the flexible elements are hinged on the shaft of the horizontal milling cutter. FIG. 1 shows the device, a general view; in FIG. 2 is a view A of FIG. one; in fig. 3 cutting of a block of soil from an array with wiring of flexible pipes; in fig. k - groove of the block; in fig. 5 device, type of super xy. A digging device including a baseline 1, to which a guide bearing body is attached, consisting of two frames, one of which, horizontal 2, is made with supporting wheels 3. The second frame, vertical k, is mounted on KapeTKig 5 with the possibility of longitudinal movement in the guides of the horizontal frame 2 by the rod of the hydraulic cylinder 6, which has been spliced on the frame 2. The vertical frame k is provided with a slider 7 with the ability to move up and down the hydraulic cylinder 8, the casing of which is fixed to the upper part of the vertical frame A, and the rod to the slider 7. On the slider 7 there is mounted a working member made in the form of chains of bar 9 installed in parallel, the lower driven stars of the daughter of which are connected by a milling cutter 10, and the driving sprockets 11 are connected via a gearbox to a hydraulic drive (not shown). In the area of the support wheels 3 on the horizon, the frame 2 is equipped with a drum 12 flexible pads with the ability to move up and down in the guides 13 hydraulic cylinders 14. The free ends of the flexible pads 15 are fixed to the vane 16, hinged to the axis of the cutting cutter 10. The device works as follows. The device is installed above the proposed location so that the baseline gauge 1 is located above the end of the marking, and the vertical frame 4 moves along the horizontal frame 2 by the hydraulic cylinder 6 to a position where the working body 9 is on the opposite end of us. When the hydraulic cylinder 8 is lowered by the slider 7 and the working body associated with it with the chains of bar 9 last and undercutting the milling cutter 10, we cut the vertical slot of the end face to the design depth. When the vertical frame is moved by the hydraulic cylinder 6, vertical slots are cut by chains 9 along the longitudinal sides, and a milling cutter 10 forms a horizontal slit under the ground block, while the wind vane knife 1b, following the milling cutter 10, pulls flexible along the sa 15. When the working tool comes to the surface from the opposite end, a block of soil is formed, which is removed by raising the working device by the hydraulic cylinder 13 to the extreme position of the vertical frame C while simultaneously raising the drum of flexible 12 hydraulic cylinders U. The proposed device for digging into a square shape allows to work in cramped conditions, and also increases the productivity of digging square meters, especially in frozen soils. The invention includes a device for digging m, including a baseline gauge, a frame with a working body in the form of two parallel vertically installed bars, connected in the lower part by a shaft with a horizontal cutter, mechanisms for raising and lowering the working body and the ground, the mechanism for feeding the working body to the bottomhole, the fact that, in order to increase productivity, it is equipped with a horizontal frame with support wheels and a movable carriage on which the frame is mounted with a working body and the mechanisms for its raising, lowering and chi is on the face, and the soil lifting mechanism is made in the form of a drum with flexible elements mounted on a horizontal frame with the possibility of vertical movement, while the free ends of the flexible hinge elements 5926177 are mounted on the shaft of a horizontal mill.
