Description

tj is the time for closing the gate of the dosing bin, and then, simultaneously with the unloading of the (n + 1) -th dose into the accumulation bin, the first dosing bin is filled with the (n + 2) -th dose, and the loading time of each subsequent dose is determined by the average productivity of bulk materials delivery over a certain period of time, for example, during the loading of the previous dose, and each dose is discharged from the storage bin into the gondola car ahead of the time of completion of the second Ovani molds, followed by the dose discharged into the gondola car. ovochnom hopper for a time not minimal amount of time and closing the shutters incremental metering hoppers and filling the collecting hopper of the first following the discharged dose in the gondola. The drawing shows one of the variants of the device that implements the proposed method. A device for implementing the method comprises a conveyor 1 with a weighing device 2, a switchgear 3f two metering hoppers 4 and 5c with locks b and 7 and hopper weights 8 and 9, an accumulation hopper 10 with locking 11, a loading chute 12 and weights 13 and a process control scheme loading 14. Scheme 14 has a sensor 15 for moving speed of gondola cars 16, which is connected to comparison blocks 17 and 18, averaging block 19, the input of which is connected to the weighing device 2 and the output with separating block inputs 20 and 21. Second inputs of block 20 and 21 are connected to the outputs of the adder 22 and 23, associated with bunker weights 8.9 and unit dose 24. The output of the dividing block 20 is connected to the summers 25 and 26, and the output of the dividing block 21 to the adder.26, which through the adder 27 is connected to the input of the separating unit 28. The second input of the adder 27 is connected via adder 29 to the time setting 30. The second input of the separating unit 28 is connected to the setting unit of length 31, and the output of the adder 25 to the separating unit input 32. the outputs of the separating units 28 and 32 are associated with the block 33 for calculating the arithmetic average, as well as with the block and comparing 17 and 18. The proposed method is realized as follows. Bulk material, for example, coal, is first fed from conveyor 1 to one of the metering bins 5 (p-dose), OPENING gate 7, transfer it to the storage bin 10, then fill the {n-fl) -u dose with the second dosing bin 4 and at the same time, opening the shutter 11, discharging material from the storage bin 10 into the gondola 16, discharging the bulk material is carried out with support, i.e. First load the gondola up to the moment when the cone of the material in the car connects with the material in the loading bar 12 (the moment of formation of the backwater), the material falls free into the car with a capacity corresponding to the free flow of the material from the outlet of the front side 12, then when the gondola 16 moves, the loading chute 12 is above its unfilled part, the material is poured out of the chute 12 with loading capacity that is proportional to the movement speed of the semi-carriage, which is maintained in a suitable range. the area defined by the relation, L4g & B, b, 4-dv v () where L; is the length of the gondola car; the distance from the loading point to the end of the gondola at the moment of termination of the unloading of the dose from the storage bin; D12 is the length of the intercarriage gap; the time remaining until the formation of the nearest (n + 1) -th dose is completed; the time over which the formation of the (n + 2) -th dose will end; t | is the time of filling the storage bin 10 (n + 1) -I dose; the closing time of the gate 11 of the storage bin 10; closing time of the dosing bin. After the storage bin 10 is emptied, the shutter 11 is closed. Then, simultaneously with the unloading of (n + 1) -th dose into the accumulative bunker 10, (. N + 2) is filled with the dosage bin 5. At the same time, the loading time of each subsequent dose is determined by the loading time of the preceding dose, and each dose from the storage bin 10 is discharged into the gondola 16, ahead of the time of the end of the formation of the second dose following the unloaded v-wagon 16 in the dosing bin 5, the time not less than the sum of the closure of the gates 11, 6 10 and the metering hoppers 4 and filling storage bin 10 following the first gondola car 16 to the discharged dose. The control of the loading process can be carried out, for example, with the help of the diagram 14 shown in the drawing. In the normal course of the process (without stopping the flow of material into the dosing bins), the dosing bin 4 is loaded (or already loaded) (n + 1) —dose, in bin 5 it will be prepared (or is already being prepared) (n + 2) - dose. After unloading the n-dose from the storage bin 10 from the exit of the balance 13, a signal is received to the control circuit of the actuator of the shutter 11, which is closed and, if (n + 1) —the dose is ready at this moment, the shutter 6 of the bunker 4 is opened and this the dose is reloaded into the hopper 10. After the emptying of the hopper 4, its shutter 6 is closed. The signals from the output of the hopper scales 8.9 are compared with the values of the dose setting (n +1) and (n +2) coming from the output of the dose setter 24. The difference between these signals is proportional to the mass that needs to be loaded into the hoppers. 4 and 5 to a predetermined value, is fed to the input of the dividing blocks 20 and 21. The second inputs of these blocks receive a signal from pin 19, proportional to the average value of the material flow on the conveyor. At the output of the dividing unit 20, a signal is obtained that is proportional to the time T required to finish the preparation of the dose (n + 1) and the output of the unit 21 is a signal proportional to the time T required to finish the preparation of the dose (n + 2). The output of the adder 26 receives a signal proportional to the sum of these times (t, + T2. At the output of the adder 29, a signal is obtained proportional to the sum of the average values of time t (close the gate of the storage bin;; tg (close the gate of the metering bin) and t (fill with dose These signals are removed from the time master output 30, and their sum goes to the input of the adder 27, from whose output to the input of the splitter unit 28 receives a signal proportional to d1 (T, + Tg) - (). To the second input of the block 28 comes from the output of the setting device for The signal 31 is proportional to the known gondola length (), into which the storage bin 10 is emptied. Therefore, the signal at the output of block 28 is proportional to the minimum allowable speed V -i:. MMM 4t The accumulator 25 is summed by signals proportional to T jj and t j. Total signal and a signal from exit 31, proportional to the known length up to the front wall of the next car L + L.lu (the width of the loaded gondola increased by the length of the intercarriage gap), goes to the input of the splitter unit 32. Then, from the output of unit 32, the signal is removed l, the maximum speed proportional ,,; , According to the obtained values of the min-unit 33, the average speed of the VCP is 0.5 (V ,, Vfц „), the value of which is transmitted to the IKOMOTHBOM control circuit. In comparison block 17, the actual speed is compared with uaiffi. In comparison block 18, the magnitude of UV is from Udim; a signal arises from output 17 if V is greater than VAKMH's output from block 18 — if less signals are also supplied to the locomotive control circuit. When one of the two signals appears in the locomotive control scheme, a command is formed to change the speed of movement of the train from V to V (.p The dosed supply of bulk material in the specified sequence and in compliance with the described time mode allows the optimal control of the speed of the gondola cars. and, while ensuring a given labor productivity, it makes it possible to increase the metering accuracy and implement the process on simpler equipment. automatic dosed loading of bulk material into moving railway gondola cars, including the supply of bulk material with overload through storage and metering bins into moving gondola cars with simultaneous speed control, characterized in that, in order to improve metering accuracy and simplify the equipment method, A dose of material is first fed into one of the metering bins, transferred to a storage bin, then filled with (n + 1), and with the dose the second metering bin and simultaneously Menno discharged from the collecting hopper nth dose bulk material wagon, the movement speed of which is maintained in the range of ratios determined emom, illlliili, T, .v (t, t.t3r ° t, and the length of the gondola.; the distance from the loading point to the end of the gondola at the moment the dose is unloaded from the storage bin; the length of the intercarriage gap;
