The invention relates to devices for loading warehouses, in particular, sequentially located storage bins, and can be used in construction, food, chemical and other branches of the native household.

The purpose of the invention is to increase productivity and reliability.

FIG. 1 shows a device ;, a general view of FIG. 2 - the same, side view; in FIG. 3, view A in FIG. 1; figure 4 view B in figure 1; Fig.5 - node I in Fig.Z; in fig. 6 - node And on fig.Z; Fig. 7 shows a safety valve design; 8, the design of the speed quencher; figure 9 is a view In fig ,.

The device for loading bulk materials with a silo includes a vertical lift shaft 1, a discharge section of a shaft 2, an inclined loading shaft 3, a transfer compartment 4, a return section of a shaft 5, an additional vertical shaft 6, mobile carriages 7 that can simultaneously be in the mines I, 69 2 and 3, for example, one in each,

In shaft 1, one of the trolleys 7 is installed, under which cavity 8 is formed, connected to - by fan 9 (and safety stops 10; In the upper part of mine 1, safety valve 1 and fan station with fans 12 and 13 are installed .

The discharge section of the shaft 2 is equipped with pneumatic cylinders 14 connected to the gates 15 mounted in the rollers 16, and pneumatic cylinders 17 connected to the gates 18.

In mine 3, pneumatic tires are installed: cylinders 14, connected to gates 19 and 20 installed in rollers 16. Mine 3 has a funnel 21.

The shaft 6 is equipped with a fan-supporting station with a fan 22, a main cylinder 14, connected to a gate 15 mounted in the rollers J6. In the mine 6, one petrol tank car 7 is installed, safety drain valves 23, dampers. 24 speeds.

Mobile carriages 7 are equipped with an autonomous unloading system, consisting of pneumatic cylinders 25, having return springs 26, a pipeline 27 with a fitting, flexible pipelines 28, a gate 29. System times

to

The loads of the carriages 7 are controlled by the pneumatic system of the shaft 2 through the pipe 30 by means of the transitional connecting body 31 having a front-turn valve 32 and a return spring 33. The carriages 7 are equipped with self-guiding wheels 34.

The valve 11 is controlled by a pneumatic cylinder 35.

The device works as follows.

When the fan 9 is turned on, air is injected into cavity B. The air pressure in cavity 8 increases. In the cavity above the carriage 7, the pressure remains equal to atmospheric because it communicates with the surrounding space through the open valve 11. The pressure difference in the cavity of the Viv cavity over the carriage 7 causes a force on the carriage 7, which moves to the upper part of the shaft 1 through safety stops 10, which sink when the wheels 34 are driven by the trolley 7, and then after the passage of the trolley 7, they return to their original position,

Each of the carts 7 passes the following cycle of work: loading in mine 3, lifting in mine 1 and moving to the desired unloading place in mine 2; unloading and movement in compartment 4; rolling down the inclined shaft 5 into the shaft 6; lowering in mine 6 and rolling down into mine 3,

At the same time and independently, the following operation can be performed; loading trolley 7 in mine 3; unloading trolley 7 in the mine 2; lifting trolley 7 in mine I; lowering the trolley 7 in the mine 6; the movement of the trolley 7 in the compartment 4; rolling trolley 7 around the mine 5.

To create an air cushion in the shaft 6, a fan 22 is turned on. In the shaft 3, the loading of the carriages 7 takes place through the funnel 21.

When the cart reaches 7 top

parts of the shaft 1 with pneumatic cylinders 14 open gates 15, which move in rollers 16; pneumatic cylinder 35 closes valve 11; the pneumatic cylinder 17 opens the gate 18 at the desired discharge point of the shaft 2, and then the fan 12 is turned on. The air pressure created by the fans 12 and 9,

moves the trolley 7 into the shaft 2. Thereafter, the gates 5 are closed; fan 12 is turned off; opens valve 11, which returns to its original position with tension springs when the rod of pneumatic cylinder 35 returns to its original position; The gate 19 is opened by the pneumatic cylinder 14. One of the carriages 7 loaded in mine 3 is moved to the shaft 1, the gate 19 is closed and the gate 20 is opened. Therefore, the other car 7 from mine 6 is moved to the shaft 3 under the loading and the gate 20 is closed; At this time, the trolley 7 with cargo moved from mine 3 to mine 1 rises to the upper part of mine 1. At the same time, fan 13 is turned on to move trolley 7 to mine 6, the air pressure generated by the fan 13, variable. pushes the carriage 7 into compartment 4 and then into the inclined shaft 5, along which with the help of self-guiding wheels 34, the carriage 7 rolls down into the shaft 6,

In the shaft 6, the pneumatic cylinder 14 opens the gate 15, which moves in the rollers 16. After that, the carriage 7 starts to descend to the bottom of the shaft 6. The airbag created by the fan 22 in the shaft 6 and the dampers 24 speeds, due to the energy absorbed by the compressed straps, allows trolley 7 to be lowered smoothly. As the trolley 7 is lowered to the bottom of the shaft 6, the pressure of the air cushion increases, so the valves 23 are actuated, thereby the pressure of the air boost is maintained at the same level, and the trolley 7 is gently lowered to the bottom of the shaft 6, then under its own weight

rolls into the shaft 3 to the gate 20, At the same time, one of the carts 7 with the load is fed for unloading. Cart 7 with a load of mine 3

5 is fed into the shaft 1. After the trolley is fed into the shaft 1, the spike 20 is opened, and the cart 7 from the shaft 6 is fed for loading into the shaft 3, the feed of the cart 7 from the upper part

10 mines 1 in any intermediate

the position of the shaft 2 is carried out as follows; The pneumatic cylinders 14 open the tongs 15 to the required place of unloading; opens shi

(5 ber 18 to the engine cylinder 17; pneumatic cylinder 35 to close the valve 11; the fan 12 is turned on and the carriage 7 moves to the unloading place; after the carriage 7 unloads, the

20 the remaining shutters 1 5 are closed and the gate 18 is closed by the pressure of the air created by the fan 12, after which the carriage 7 is moved,

25 The carriage 7 can be unloaded along the entire length of the shaft 2,

The unloading of the trolley 7 is carried out as follows. Air from the pneumatic system with mine 2 through pipe 30

30 is given to the housing 31, while the valve 32 is moved to the fitting of the pipeline 27, and the air through the flexible pipes 28 enters the pneumatic cylinders 25, which open the container gate 29 and the cargo is poured out of the carriage 7,

After stopping the supply of air from the pneumatic system of the shaft 2 through the pipe 30, the pneumatic cylinders 25 with the help of springs 26 close the gate 29, B this. At the same time, the spring 33, the valve 32 returns to its original position in the housing 31,
