A bunker-loader is known, which includes a tank with outlet hatches, overlapping gates, and a conveyor, the traction body of which is located above the tank and then passes through the system of deflecting drums under the outlet hatches.

The disadvantages of such a bunker-overload - relatively small useful

capacity, design complexity and its unsuitability for materials prone to sticking due to sticking capacity.

Known bunker-loader, including the tank, the loading conveyor, the cargo branch of which is located in the lower part of the tank in the box, and the discharge conveyor, both branches of which are located under the tank.

The disadvantages of such a bunker-reboiler are relatively small useful capacity, design complexity and its unsuitability for materials prone to sticking due to sticking of the container.

gears that control the position of the bottom, and the conveyor, the upper branch of which is located above the tank and the lower branch below it.

The disadvantages of such a storage bin are relatively small useful capacity, design complexity and its unsuitability for materials prone to sticking, due to the use of heavy and traumatic manual labor for cleaning the capacity of the bunker in the process of unloading sticking materials.

The purpose of the invention is to increase the storage capacity of the storage bin, simplify the design and increase the efficiency of unloading adherent materials.

The goal is achieved by the fact that in a storage hopper that includes a container with an opening bottom and a conveyor, the upper branch of which is located above the container, and the lower one is below it, the container with the opening bottom is made in the form of a trellised frame and is equipped with levers, power cylinders, longitudinal bars and elastic elastic material. At the same time, the levers and power cylinders are hingedly attached to the lower part of the lattice frame; An elastic resilient material is fixed on the inner side of the lattice frame, the lower part of which is freely placed on the longitudinal rods.

FIG. 1 shows a storage bin, general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows section A-A in FIG. 1 with open noon; in fig. 5 is a section BB in FIG. 3; in fig. 6 is a diagram of the loading of the rock mass on the main conveyor; in fig. 7-diagram of the loading of the storage bin; in fig. 8 - - storage hopper unloading scheme; in fig. 9 is a diagram of loading the rock mass onto the main conveyor with simultaneous unloading of the storage hopper.

The storage hopper includes a container 1 with an opening bottom and a conveyor 2, the upper branch of which is located above the container and the lower branch below it. The container with an opening bottom is made in the form of a trellised frame 3 and is equipped with levers 4, power cylinders 5, longitudinal rods 6 and an elastic resilient material 7, for example, a rubber cable conveyor belt. The arms 4 and the power cylinders 5 are pivotally attached to the bottom of the frame 3. The arms 4 are made with a slope in the vertical plane, and in the horizontal plane they are located at an acute angle (60-75 ° C) to the longitudinal axis of the tank. On the free ends of the levers 4 pivotally, with the possibility of movement in the horizontal plane, longitudinal rods 6 are installed. On the inner side of the lattice frame there is fixed elastic elastic material 7 forming the walls of the container. The lower part of the walls is bent inside the lattice frame and freely placed on the longitudinal rods 6, forming the bottom of the tank. The upper branch of the conveyor 2 is located above the tank and is used to load the tank. In the area from the feed conveyor

8 before the beginning of the tank 1 under the upper branch of the scraper conveyor 2 the bottom is installed

9 with a hatch in the area of the main conveyor 10, with the lid closed 11. The lid 11 is hinged to the bottom 9 of the conveyor 2 and through the double-arm lever 12 it can be opened to pass cargo through the hatch from the feeding conveyor 8 to the main conveyor 10 or close to deliver the cargo on the bottom 9 in the capacity of 1 storage bin. The lower leg of the conveyor 2 is located below the tank and is used to unload the tank. It travels along guides with a blind bottom, which ends in the zone of unloading cargo onto the main conveyor 10.

Works bunker as follows.

The mountain mass can be reloaded from the feed conveyor 8 to the main conveyor 10 (FIG. 6) with the scraper conveyor 2 inoperative. At the same time, the cover 11 of the upper branch of the conveyor 2 is open, and the mountain mass from the feed conveyor 8 through the hatches in the bottoms of the upper and lower branches conveyor 2 enters the main conveyor 10. Capacity 1 storage hopper (Fig. 7) is loaded as follows. The bottom of the tank and the cover 11 of the hatch of the upper branch of the conveyor 2 are closed, the conveyor 2 is on. The mountain mass coming from the feed conveyor 8 to the upper branch of the conveyor 2 moves by scrapers along the bottom to the tank 1. When the height of the accumulated rock mass reaches the level of the scrapers of the upper branch of the conveyor 2, the scrapers move it to the free part of the tank 1, gradually filling the last one. Unloading capacity 1 hopper drive to the main conveyor

10 is produced when the supply conveyor 8 is inoperative in case of different types of cargo in the storage hopper and coming from conveyor 8 (Fig. 8), and if they are of the same type, simultaneously with the overload of the rock mass by conveyor 8 on the main conveyor 10 (Fig. 9). For this cover 11 hatch bottom

The upper branch of the conveyor 2 is opened and the conveyor 2 is turned on. The power cylinders 5 are turned on to contract, and the rods 6, moving along the tank, are simultaneously displaced to its walls, and the bottom is under the action of the elastic forces of the bottom material and the gravitational forces of the load. As a result, an outlet slot is formed between the bottoms along the entire length of the container. The size of the gap is adjusted, the length of the power cylinders is changed. 5. Simultaneous opening of two bottoms is possible. If necessary, you can open only one bottom, or sequentially: one, and as the container is unloaded - another. The bottoms in the open position are lowered by the ends on the scrapers of the lower branch of the conveyor 2 and serve as its sides. When expanding the power cylinders 5, the rods b move from the tank walls to the middle and, overcoming the elastic forces of the material of the bottoms, bend them down and close the outlet slit 1. When the bottoms open and close, and when the ends of the open bottoms interact with the moving scrapers of the lower branch - Weier 2, the resilient elastic material of the bottoms and walls is deformed. As a result of deformations, the adhered material is detached / A

The tank surfaces are self-cleaning, and the exfoliated material is poured onto the conveyor. If necessary, for a more complete cleaning of the tank, re-close and open the bottom.
