Description

Devices are already known for determining the grind current, made in the form of weights for weighing the residue that has not passed through a sieve and equipped with sieving to pre-screen Lveski material.

The proposed device for determining the clogging of bulk materials, for example, a shag, equipped with a sampler, intermittently intersecting the free fall, a U1O stream of material, has the feature that the material passed through the sieve for loading one weighing pan and the other dish - sifting and digging little things are made periodically tilting-and. into the funnels of the scales.

In FIG. 1 shows a front view of a part of the device in an exemplary form of its implementation; FIG. 2 is a front view of another part of the device; FIG. 3 is a side view of a part of the device of FIG. 1, fig. 4 is a top view of the scales of the device of FIG. 1 to 2, FIG. 5 is a top view of a detail of the scales of FIG. four.

The device is set in motion by an electric motor (or a motor) using bevel gears 1 TL 2. An eccentric 4 is fixedly fixed on the central axis 5 4. A ring 5 is fixed on the eccentric, and the horizontal rod 6 fixed between the vertical stand 7 and bent down is fixed finger S. Thus, due to the retaining rod 6, the ring 5 cannot rotate together with the eccentric 4, and the latter rotates inside the ring, causing it to make the movements necessary for sifting. A pad 9 is rigidly attached to the ring 5, moving together with the ring. On the central axis 3, two U and U worms are fixedly fixed, and the lower one to / O has its own center, axis 3, and the upper one to // has its center to the eccentric axis 4. From the screw 10, the lower gear system moves, and from Worm // - top system, mounted on site 9.

From screw 11, gear 12 is set in motion, on the axis of which the screw is fixed to 7.3. From the latter, gear 14 is set in motion, on the axis of which a pre-baby 15 is mounted, which is a DIET feral with several teeth protruding on it in one place. As the central axis 5 rotates, the comb 15 also rotates by the hour-arrow. Next to the comb 15, there are two 1milk shchorni 16 and 17, On the axis of the scooper 17, one or two rods 18 are fixed, supporting the sowing 19 with its funnel 20. As long as the tooth of the comb 15 moves between the scraper 16 and 17, all this rest; only sifting takes place, and fines, pass through the s. asev sieve, and replace it with a funnel 20 into the bucket 21, which is fixed on the axis 22.

To control bucket 21, for loading. cups 25 of the device weights through the funnel 24, the axis carrying the gear 16 is equipped with a crankshaft connected by a rod 23 (Fig. 3) with a crank of the axle 22 of the bucket 21. The same crankshaft of the axis 22 is connected to the crank 26 of the gear axis / 7. Rotation of gears 17 and its axles leads to tilting of the sieving 19 with the funnel 20 to the position / 9a, 20a (Fig. 1), in which the rod / S abuts against the stop 27, and not the shag particles that pass through the sieve of sieving, load the second cup 29 funnel 28. The gear 17 is also designed to return to the initial position of the bucket 21 "sieving / 9 with a funnel 20, interacting with the teeth and the comb 15, with its further rotation. As a result of one rotation of the comb 15, the cups 25 and 29 of the balance are loaded correspondingly with 1 small and. not passed through sifting shag particles for one of its samples.

With two worm gears (worms 10 and 31, gears 30 and 32), the rotational speed of the central axis 5 decreases by the same number of times as in the upper system. On the axis of gear 32, there is also a comb 55, shown separately in FIG. 2

Comb 55 is rotated counterclockwise. As the teeth move between gears 34 and 35, the entire mechanism that controls the weights of the MiH is inactive. The balance beam 40 (fig. 4) at this time is raised and gives a signal - the result of the previous erection. When eub approached gear 35, it will turn clockwise and with the help of lever 57 will turn the eccentric tkkk 39, as a result of which the beam 40 weights will lower. At the same time, gear 34 is turned counter-clockwise by the lever 5S. When reaching gear 36, comb 55 causes it to turn clockwise. The lever 41 transmits the movement of the gear 42, which is engaged with the smaller gear 43. Thus, the gear 43 rotates counterclockwise, and it can turn any angle, depending on the ratio of gears 42 and 43.

The desired angle of rotation of the gear 43 - about 180 °, the implementation of the difficulties will not present.

Pin 43 is fixed on pinion 43 (Fig. 5), having a slot, and the weighing pan has rods at the bottom, which, when raised, goes out of the plug, and when lowered, enters its slot.

When the barn 43 turns, the bark of the scale 40 is lowered and rests on the stops that lock the rocker (not shown).

The core of the cup fits into the slot of the plug. The fork moves with gear 43 and turns the cup, which rests, instead of a prism, on two heels, as shown in FIG. 4, and therefore can rotate freely. This movement is simultaneously transmitted to the second weighing pan by means of a lever 45 and two gears 46 and 47, and the same fork 44 is fixed on gear 47. The only difference is that the jaw 47 rotates clockwise. When the tooth of the comb 55 comes off the pinion 36, the whole turning mechanism

is set to its original position by means of a spring 48.

After pouring out the previous sample, the cups of the Akasi1 are prepared for us to accept the next. At this point, the upper system reverses the sieving and the bucket 21 for small items. Cup 25 takes a trifle, and Cheshka 29 - a part; Ki shag.

The tooth of the comb 55 approaches the bristle 34, the lifting mechanism returns to its original position, and the balance begins to balance.

The ratio of their shoulders is such that THEY are in equilibrium when the content of trivia is equal to the limit allowed by the standard. If the trivia content is greater than the allowable limit, pushes the cup 25, closes the contact ///, and the red light flashes. If the trivia content is less than the allowable limit, P1 29 is turned off, contact II is closed, and a blue light bulb is blown out. The skimmer has a MiecTo while the comb teeth 55 move between gears 34 and 55.

The rotation of the comb 33 by means of bevel gears 49 and 50 is transmitted to a vertical shaft 5 /, at the top of which a fork 52 is fixed. In the slot of the fork on two heels there is a sampler 55. 54, touches the aa of its edge, bends, AND (moving further, touches with its visor 55 against the stop 56, reinforced inside the funnel, as a result of which the Sampler turns over and the sample enters through the funnel 54 into the screening 19.

Thus, the apparatus operates continuously. While one sample is sieved, the signal is lit — the result of the previous sample, and the sampling. in the meantime, is sent for the next sample.
