Description

At present, usually, beets delivered to railway stations are stored in station warehouses in stacks up to a height of several hectares. From the stacks, the beets are usually manually reloaded into wagons, which slows down the loading and requires a significant number of workers, whereas during this period of time (September-but-a-bri) labor is needed for autumn field work. This circumstance raises the question of the mechanization of loading operations. But since the beet loading stations mostly lack electric energy and water, why the use of any mechanisms, such as: conveyors, beet grabs, crane installations and other such costly devices cannot be effectively used therefore, a fully locally adapted mechanism of a simple device and not requiring electrical or other energy can play a significant role in the matter of quickly and without damage to the product of loading it into the wagons, which is the purpose of this redlozheni on the application of "grab-scraper. A grapple, equipped with movable sash claws, collects the beets from the piles and delivers them to the bunker mounted on

at a height of 7-9 m above the loading way, from where the beets are poured into the carriage. Station warehouses in this case should be located in the form of sectors with a radius of 150-200 m, and in the center there are bunkers, B, due to the local conditions of the station warehouse and the location of loading tracks. A conventional winch type is used as a driving force.

In FIG. 1 and 2 depict a grab in two projections.

The grab-drag harness consists of an iron welded box 7 with two side walls and a bottom on the skid x. At one end of the box there are two hinged, folding clamps A and B hinged to the two shoulders and fitted at the ends with steel forks / O with blunt ends. The short arms of the ears with ears 5, 5 are connected to the cable 6, which goes to the winch drum of the usual scraper type, in order to hold the grippers A and B in the open position, when the grips cut into the beet pile.

The bottom of the box comes forward in the form of a blunted visor. The working cable 7 with its branches extends over the rollers 3, 3, which sit loosely on the axles fixed in the channel shelves of the corner fastener. For freer and easier rope movement

the rollers have free movement on the axis x in the vertical direction (Fig. 2). The branches of the cable 7, passing through the rollers and crossing, are attached at their ends to the lugs riveted to the clamps A 1 B B (Fig. 1). The stops 2, 2 serve to fix the position of the grippers A and B when the latter are in the closed position. The effect of the grapple grab is as follows. The grips A and B in the closed position (Fig. 1) are brought to the open position up to the stop 9 by means of a cable 6, the idle drum brake is braked in order to prevent the arbitrary closure of the jaws when they pierce a beet pile. In such a state, the drag line moves to the stack, slamming it into the stack and catching the beets, directing it to the stack, after filling which the brake 6 turns off and at the same time actuates the cable 7, the grippers A vt B close and the drag line moves to the bunker, lifting it along the slope of the rails, which are bent down at the top at an angle of 45-50 to the horizon, so that, by feeding the drag line to the highest position through the tray, the drawer / beetroot is poured into the bunker, and from the latter is poured into railway carriage.

The subject matter of the invention.

The grab is a drag

in that it is provided with two closure flaps, A, B, which serve to direct the material into the hauling box.
