This creation utilizes the dead material pile when the material is accumulated to form a natural enclosure structure, and the enclosure wall structure of the silo can no longer be set up.

The working principle of this creation is as follows: when the reversible conveying device 3 is rotating and feeding materials, the first lifting mechanism 1 and the second lifting mechanism 2 lower the bending point drum 32 and the lifting frame 7 to the low point, and first pass through the lifting frame 7 The door opening and closing mechanism 6 closes all the doors 61 on the bottom layer. Then it rises so that the lower unloading hopper 5 on the lifting frame 7 is aligned with the second-layer material passing window 111 , and the material is sent to the lower unloading hopper 5 provided on both sides through the head hopper 8 and the branch material pipe 9 respectively, and then passes through the discharge port 51 Using its own weight, the material is fed into the silo through each feeding window 111 on both sides of the second layer. As the height of the material in the silo rises and reaches the material passing window 111 of the second floor, the door opening and closing mechanism 6 closes the door leaf 61 of the second floor, and then the first lifting mechanism 1 drives the lifting frame 7 to rise by a step height, allowing the lower The discharge hopper 5 is aligned with the pass window 111 of the third layer, and discharges continuously. In this way, the head drum 31 of the reversible conveying device 3 and the highest point of the material in the silo are always kept within a height range. When the angle of the conveyor belt 33 between the head drum 31 and the bending point exceeds the maximum allowable inclination angle, the second lifting mechanism 2 lifts the bending point drum 32 to the last fixed point, and circles like this until the lower discharge hopper 5 reaches the highest level .

When the reversible conveying device 3 reverses and discharges the material, the first lifting mechanism 1 and the second lifting mechanism 2 raise the bending point drum 32 and the lifting frame to the high point, first align the upper loading hopper 4 with the door leaf 61 of the next high level, and then The door leaves 61 on both sides of the layer are all opened by the door opening and closing mechanism 6, and the material is passed through the material passing window of the layer. The port 111 slides into the top loading hopper 4 , and then slides into the conveyor belt 33 of the reversible conveying device 3 after being collected. After the material level in the silo drops to a certain height, the first lifting mechanism 1 drives the lifting frame 7 to lower a step height, so that the upper loading hopper 4 is aligned with the door leaf 61 of the next floor, and then the opening and closing door mechanism 6 separates the two floors. The side doors 61 are all opened to discharge the silo. In this way, the head drum 31 and the lowest point of the material in the silo are always kept within a height range. When the angle of the conveyor belt 33 between the head roller 31 and the bending point exceeds the allowable maximum inclination angle, the second lifting mechanism 2 lowers the bending point roller 32 to the next fixed point, and circles like this until the upper loading hopper 4 reaches Lowest level. Completely remove the live stockpile in the silo, and the remaining material that cannot be discharged by gravity is the dead stockpile.

Through the above solution, the first lifting mechanism 1 and the second lifting mechanism 2 arranged on the head of the reversible conveying device 3 cooperate with the bending point to ensure that the inclination angle between the conveyor belt 33 and the horizontal plane meets the maximum inclination angle requirement for conveying specific materials. . When the reversible conveying device 3 is forwarding to the silo for feeding, the distance between the blanking point and the highest point of the silo stack is controlled to a minimum value, and the height difference between the head and tail of the conveyor belt 33 is reduced, which can reduce the power output; when reversible conveying through the silo When the device 3 reverses the external feeding, the distance between the blanking point and the belt receiving hopper is controlled to a minimum value, and the height difference between the head and tail wheels of the reversible conveying device 3 is increased, which can increase the power output, and make full use of the weight of the material flow and the speed of the conveyor belt.
