The empty rail is a transport facility which is not contacted with the ground, and the goods are hung below the empty rail. The empty rails in this embodiment are lifting containers 9 which are brought one by one into the loading station in the direction of arrow B in fig. 1 (for reasons of drawing limitation, only one set of two containers is shown in fig. 1) and are loaded with coal. Because the movement speed of the empty rail truck is faster, and the movement of the conventional truck at the loading station of the automatic bulk material is lower, the problem of improving the loading speed is mainly solved by the embodiment.

In order to solve the problem that the moving speed of the empty rail freight car is higher in the loading process, the embodiment is provided with a plurality of weighing bins for alternately proportioning and weighing so as to accelerate the quantitative weighing speed, and a movable buffer bucket is arranged at the same time, and the buffer bucket moves forwards along with the empty rail freight car in the unloading process of the container so as to fight for the time for filling the container.

For example, a group of two containers, four weigh bins are oppositely disposed, the first two weigh bins charging a first container in the group of containers and the second two weigh bins charging a second container. Thus, the round reciprocation can keep up with the fast moving rhythm of the empty rail freight car.

In order to solve the problem of rapid movement of the empty rail freight car, the movable buffer hopper moves along with the container during unloading, which is equivalent to slowing down the movement speed of the empty rail freight car. The movable buffer hopper can have various movement schemes, such as a trolley, so that the trolley carries the buffer hopper and moves along with the container. The moving speed of the movable buffer hopper is lower than that of the empty rail freight car, and the movable buffer hopper receives the unloading of different quantitative bins in the moving process, so that the alternate unloading of different weighing bins is realized.

The weighing bins are arranged on the same plane, and the positions of the weighing bins correspond to the batching gates of the buffering bins one by one.

Fifth embodiment:

the embodiment is a loading method of the rapid quantitative loading system using the empty rail freight container.

Each two adjacent empty rail freight cars are organized into a group, each cycle is a group of two empty rail freight cars and the container carried by the same, each group of container numbers are 1# containers, and the former is 2# containers;

the two movable buffer hoppers and the telescopic boxing chute are respectively numbered as follows: the right side is provided with a 1# buffer hopper, a 1# telescopic boxing chute, and the left side is provided with a 2# buffer hopper and a 2# telescopic boxing chute; the buffer bucket is positioned in front of the loading position when the container enters the loading position, and the buffer bucket is positioned behind the loading position when the container leaves the loading position; the loading position refers to an empty rail section through which an empty rail cargo truck performs loading and unloading operations;

the weighing bins are respectively numbered as follows according to the entering direction of the empty rail freight car: the right is 1 group of weighing bins, and the left is 2 groups of weighing bins; the front of the 1 group of weighing bins is a 1-1# weighing bin, and the rear of the 1 group of weighing bins is a 1-2# weighing bin; the 2 groups of weighing bins are preceded by a 2-1# weighing bin and followed by a 2-2# weighing bin, as shown in fig. 3, wherein arrow B indicates the entering direction of the empty rail truck.

The unloading gates of the buffer bins are respectively numbered as follows according to the entering direction of the empty rail cargo truck: the right is 1 group of gates, and the left is 2 groups of gates; the front part of the 1 group of gates is a 1-1# gate, and the rear part is a 1-2# gate; the front part of the 2 groups of gates is a 2-1# gate, and the rear part is a 2-2# gate. Since the surge bin discharge gates are in one-to-one correspondence with the weigh bins, each gate number can be referenced to the weigh bin position in fig. 3.

The steps of the method are as follows, and the flow is as shown in fig. 4:

step 1, batching: before a group of containers enter a loading place and in the process of entering the loading place, the buffer bin sequentially opens the batching gate to mix materials for four weighing bins, and the sequence is as follows: 1-1# weighing bin, 1-2# weighing bin, 2-1# weighing bin and 2-2# weighing bin;

the above-mentioned batching process means that batching is performed in this order at a certain stage of the container loading process. Because the containers enter the loading space one by one to be continuously loaded in the continuous loading process of the containers, the emptying sequence of the weighing bins is 1-1# weighing bin, 1-2# weighing bin, 2-1# weighing bin and 2-2# weighing bin, so that the emptying weighing bins can only be subjected to batching operation according to the sequence, but when the loading process is in the initial stage, all the weighing bins are emptied, at the moment, four gates of the buffer bin can be simultaneously opened to simultaneously batching the four weighing bins, so that batching efficiency is improved, or various sequences such as two weighing bins are firstly loaded, two weighing bins are later loaded, and the like are only needed to be adjusted to meet various requirements of the site.

Step 2, front half of the # 1 container is filled: firstly, batching and weighing the 1# weighing bin, wherein a 1# buffer bucket is positioned in front of a loading space, and then the front half part of a 1# container enters the front of the loading space; the 1-1# weighing bin opens a discharge gate, the 1-1# weighing bin is used for filling the front half part of the 1# container through a 1# buffer hopper and a 1# telescopic boxing chute, and the 1# buffer hopper and the 1# telescopic boxing chute start to move towards the rear of the loading position at the same time, and when the 1# buffer hopper and the 1# telescopic boxing chute reach the middle of the 1# container, the front half part of the 1# container is filled with materials;

when the 1-1 weighing bin discharge gate is opened, the 1 buffering hopper and the 1 telescopic boxing chute start to move towards the rear of the loading position, the empty rail freight car is always moving, and the moving speed of the 1 buffering hopper and the 1 telescopic boxing chute is lower than that of the empty rail freight car, so that the moving speed of the empty rail freight car is reduced, and the time is striven for discharging. If the buffer hopper and the telescopic boxing chute do not move, the empty rail freight car can quickly pass through the discharge opening of the buffer bin, and the discharge flow speed of the material cannot keep up with the movement speed of the empty rail freight car, so that the material cannot fill the container. Therefore, the buffer hopper and the telescopic boxing chute are necessary to move in the unloading process, so that the problem of excessively high moving speed of the empty rail freight car is solved.

Step 3, loading the rear half of the No. 1 container: 1# to 2# weighing bins are matched and weighed; when the 1# buffer hopper and the 1# telescopic boxing chute reach the middle of the 1# container, the 1-1# weighing bin is emptied, the 1-1# weighing bin is closed to discharge the gate, meanwhile, the 1-2# weighing bin is opened to discharge the gate, and the 1-2# weighing bin discharges the rear half part of the 1# container through the 1# buffer hopper and the 1# telescopic boxing chute; when the rear half part of the 1# container reaches the rear of the loading space, the 1# buffer hopper and the 1# telescopic loading chute also reach the rear of the loading space, at the moment, the 1-2# weighing bin is emptied, the rear half part of the 1# container is full, the 1-2# weighing bin closes the discharging gate, the 1# container finishes loading and leaves the loading space, and then the 1# buffer hopper and the 1# telescopic loading chute return to the front of the loading space;

in the actual loading process, before the 1# buffer hopper and the 1# telescopic boxing chute reach the middle of the 1# container, the discharge gate of the 1-2# weighing bin should be opened, that is to say, the discharge gate of the 1-1# weighing bin is overlapped with the opening time of the discharge gate of the 1-2# weighing bin for a certain period, so that loading is more uniform, and the phenomenon that bulk materials are concaved in the middle of the container is avoided.

After the loading of one container is finished, the buffer hopper and the telescopic boxing chute reach the rear of the loading space, and cannot continue to advance along with the empty rail freight car, and do not need to advance, so that the buffer hopper and the telescopic boxing chute need to be reset to return to the position in front of the loading space, and the next empty rail freight car arrives. However, the resetting requires time, and the next empty rail truck enters the loading space immediately before the next empty rail truck reaches the loading space. If only one set of movable buffer hopper is used, the empty rail freight car which cannot cope with the rapid movement continuously enters the loading space, so that the two sets of movable buffer hoppers are required to work alternately, and the purpose of coping with the empty rail freight car which moves rapidly can be achieved.

Step 4, front half of the 2# container is filled: 2# 1 weighing bin is used for proportioning and weighing; the buffer hopper 2# is positioned in front of the loading space, and then the front half part of the container 2# enters the front of the loading space; the 2-1# weighing bin opens a discharge gate, the 2-1# weighing bin is used for filling the front half part of the 2# container through a 2# buffer hopper and a 2# telescopic boxing chute, and the 2# buffer hopper and the 2# telescopic boxing chute start to move towards the rear of the loading position at the same time, and when the 2# buffer hopper and the 2# telescopic boxing chute reach the middle of the 2# container, the front half part of the 2# container is filled with materials;

the unloading of the No. 2 container is actually repeated on the unloading of the No. 1 container, and only the No. 2 buffer hopper and the No. 2 telescopic loading chute are used for competing for the time of unloading the continuously running empty rail freight car.

Step 5, loading the second half of the No. 2 container: 2# 2 weighing bin is used for proportioning and weighing; when the buffer hopper 2# and the telescopic boxing chute 2# reach the middle of the container 2#, the weighing bin 2-1# is emptied, the weighing bin 2-1# is closed to discharge the gate, meanwhile, the weighing bin 2-2# is opened to discharge the gate, and the weighing bin 2-2# discharges the rear half part of the container 2# through the buffer hopper 2# and the telescopic boxing chute 2 #; when the rear half part of the No. 2 container reaches the rear of the loading space, the No. 2 buffer hopper and the No. 2 telescopic loading chute also reach the rear of the loading space, at the moment, the 2-No. 2 weighing bin is emptied, the rear half part of the No. 2 container is full, the 2-No. 2 weighing bin closes the discharging gate, the No. 2 container finishes loading and leaves the loading space, and then the No. 2 buffer hopper and the No. 2 telescopic loading chute return to the front of the loading space; and then returning to the step 1, loading the next group of containers.
