Description

bars 26. The extreme position of the screen shown in the drawing corresponds to the extreme position of the levers 18. At the time the gravel is released from the bunker, the screen 3 is in the position corresponding to the upper position of the handle LIT. By pressing the knobs on the lever, the thunder rises, and the gravel on it shakes, which results in a better passage through the thunder. On passing the entire gravel, through the thunder of the handle of the lever 18, it is brought to its lowest position than a kind of weathering of the thunder is achieved. At the same time, large particles of gravity are retained on it, and the remnants roll onto the platform 12.

Below screen 3 is screen 4, approximately the same design and device as the first one. This screen 4 is set in motion by the levers 19, is supported by edges on the bar 27 and is equipped with a tensioned net grid 29 which retains all particles larger than six meters and allows more fine particles of gravel to pass through. The screen 4 in the lower position is lowered into a tank 5 filled with water, the size of which corresponds to the size of screen 4 and filled constantly with water through pipe 34 (Fig. 2). The gravel spilled on the screen 4 falls on it when it is in the lower submerged position. By pressing the knob on the levers 18, the gravel is grated on screen 4, the trifling is sorted by washing the gravel. By moving the handles of the levers 19 to the lower position, the washed-off gravel is thrown off the screen, falls onto the inclined boards 11 and then drops into heaps, or directly into the wheelbarrows approaching close to the retaining walls 15. The fine change falls through the sieve and, due to the device of the inclined bottom of the water tank, it goes down. As this little thing accumulates, the hinged parts of the shield 11 are opened, and thus the access to the outer walls of the tank is obtained. Two or one of the longitudinal walls 7 of the tank are made in their lower part folding on the hinges; they have 8 stops each, with the help of which both the bolts 9 fixed on the bottom of the tank are held in place, blocking the outflow of water. With

the need to clear the water tank of the little things accumulated in it open up parts of the shields and, gaining access to the bolts 9, turn them to the side; thus freeing the wall 7 from the constipation, it is opened by the Flow of water; all small things are carried out in the market 10 and settled down. his mouth. Accumulated on the flaps 12 Large face, as necessary, discharges their vehicles into cars. It is possible to facilitate this work by tem) that the shield 12 is hinged on the supporting bars on the pins 22 and, after releasing it from the outer pivot, the pad in an inclined position, drops the gravel into specially substituted cars.

The entire apparatus of J peptic on four racks 13; the levers rest on the brackets 20 mounted on the tinctures 14. The water tank is designed to be drained on both sides; if water is used in one direction, then an additional shield b should be inserted into the tank (Fig. 1).

Subject Patent a.

1. An apparatus for washing and sorting gravels, characterized by the use of two screens 3 and 4, one above the other: the top 3 with larger, holes, and the bottom 4 with smaller, each consisting of two halves, thus hinged around each other in such a way, the screen is represented at times of periodic load of material, in the form of a chute with an obtuse angle between the sides, which can be tilted by means of levers 18 and 19, in reverse directions, i.e. with the fall from the intersection lines to the sides, for dropping the material that did not fall through the screen holes, of which screens the screen 4 with its lower part is immersed in a water tank 5, which is equipped with a bottom bottom and folding on the loops with one or two walls 7 held by in the position that blocks the exit of water through the stops 8.

2. Use together with the apparatus, which is located in Section 1, of the bunker 2, in the form of a cholot, a trough with bottom walls folding on the loops to periodically feed the material to the underlying roar 3.
