SU20113A1 - Tool for digging earth - Google Patents

Description

In the present invention, with regard to devices for digging the earth, a number of already known methods and devices were applied, namely: 1) moving the device suspended from a two-axle car in the type of cableways, made as clips with running blocks placed between the walls and moving. the tensioned rope between the racks is carried out with the help of two branches of a cable that are attached to the trolley; 2) the working elements of the fixture are controlled by a forked cable thrown over the blocks fastened on these elements, and 3) removable teeth of the digging elements used to break up the material, fastened with them by means of a dovetail fixture. The proposed device for digging earth, which can be simultaneously with the replacement of digging elements of the same type — with other devices for lifting weights, loose bodies, hay, straw, etc., consists of a metal frame to which a trough is attached.

excavations, the bottom of which are digging elements, equipped with wings extended upwards and detachable teeth, and moving from the working position to the non-working through a system of tilting levers equipped with blocks covered by a working cable, which controls the operation of the device.

PATENT TO INVENTION

DESCRIPTION

loading, unloading, and power tool for. monorail cable carriages.

To the patent of A.N. Shaurov, dated January 15, 1929 (No. 38867).

On granting a patent Published April 30, 1931. The patent is valid for 15 years from April 30 1% 1 year.

For loading, unloading and moving the monorail cableway at the load site, the end of the carrying rail is connected to the rest of the rail by a hinge and, through a system of levers, springs, and t, opens the material access from the bunker to the trolley and when filled, turns on the electric motor that informs the trolley to the place of loading.

When approaching the place of unloading, the stop stops the car, which lies further in motion, closes the electrical circuit, causing a movement of a system of levers that connect the first motor and turn on another one, which informs the car of the reverse movement under load. When approaching the load site, the trolley is placed in the working position by means of contact with a guide rest stop,

In FIG. 1 shows a diagram of the general arrangement of the parts of the loading, unloading and driving device; . FIG. 2-part of the device end of the supporting rail; FIG. 3 and

two projections of the track guide stop for placing the carriage in the operating position.

Bearing rail 1 (Fig. 1) is a monorail tollway, the lower one supporting two rollers supporting the load carriage 10, ends at the loading point of part o (Fig. 2) connected to part of the same rail through a hinge 2. The opposite end of the rail 6 is pivotally connected by a rod 3 to one shoulder of the double-arm lever 4, the other arm of which is connected to the spring 5, which holds the lever 4 in the equilibrium position when there is no carriage on the rail b. The same lever arm 4, when the spring 5 is stretched, comes into contact with the load P, which balances the cart until its full load. On the one hand, the same end of the rail b is connected through a flexible cable with a gate 7, a spring b pressed and intended to keep the wing drum 8 from rotation, through which the loaded material enters the hopper through channel 9 into the cargo railDate: 26/12/2001
