The utility model utilizes the dead material pile in material accumulation to form a natural enclosure structure, and the enclosure structure of the silo can be omitted.
The working principle of the utility model is as follows:
when the reversible conveying device 3 is loaded in a forward rotation manner, the first lifting mechanism 1 and the second lifting mechanism 2 both lower the bending point roller 32 and the lifting rack 7 to a low point, and the bottommost door leaf 61 is completely closed through the door opening and closing mechanism 6 on the lifting rack 7. Then, the material is lifted to enable the lower discharging hopper 5 on the lifting frame 7 to be aligned with the material passing windows 111 on the layer 2, the material is respectively conveyed to the lower discharging hoppers 5 arranged on the two sides through the head hoppers 8 and the branch material pipes 9, and then the material is conveyed into the storage bin through the material passing windows 111 on the two sides of the layer 2 by the self weight through the material outlet 51. Along with the rising of the height of the materials in the silo and before the materials reach the material passing window 111 on the 2 nd layer, the door opening and closing mechanism 6 closes the door leaf 61 on the 2 nd layer, and then the first lifting mechanism 1 drives the lifting rack 7 to rise by a stepping height, so that the lower discharging hopper 5 is aligned with the material passing window 111 on the 3 rd layer and continuously discharges the materials. The head roller 31 of the reversible conveying device 3 and the highest point of the materials in the silo are always kept in a height range in such a circulating way. When the angle of the conveyor belt 33 between the head roller 31 and the bending point exceeds the maximum allowable inclination angle, the second lifting mechanism 2 raises the bending point roller 32 to the upper fixed point, and the process is circulated until the lower discharging hopper 5 reaches the highest level.
When the reversible conveying device 3 reversely discharges materials, the first lifting mechanism 1 and the second lifting mechanism 2 lift the bending point roller 32 and the lifting frame to a high point, so that the upper charging hopper 4 is aligned with the second-highest door leaf 61, then the door opening and closing mechanism 6 opens all the door leaves 61 at two sides of the layer, and the materials slide into the upper charging hopper 4 through the material passing window 111 of the layer and slide onto the conveying belt 33 of the reversible conveying device 3 after being collected. After the material level in the silo is lowered to a certain height, the first lifting mechanism 1 drives the lifting frame 7 to descend by a stepping height, so that the upper loading hopper 4 is aligned with the door leaf 61 of the next layer, and then the door leaf 61 on two sides of the layer is completely opened by the door opening and closing mechanism 6 to unload the silo. The circulation is carried out, and the head roller 31 and the lowest point of the materials in the silo are always kept in a height range. When the angle of the conveyor belt 33 between the head roller 31 and the bending point exceeds the maximum allowable inclination angle, the second lifting mechanism 2 lowers the bending point roller 32 to the next fixed point, and the process is repeated until the upper hopper 4 reaches the bottom layer. The live material pile of the silo is completely removed, and the residual material which can not be discharged by self-flow is a dead material pile.
Through the scheme, the head of the reversible conveying device 3 is matched with the first lifting mechanism 1 and the second lifting mechanism 2 at the bending point, so that the inclination angle of the conveying belt 33 and the horizontal plane meets the requirement of the maximum inclination angle for conveying specific materials. When the reversible conveying device 3 forwards rotates to feed materials to the silo, the distance between the blanking point and the highest position of a silo material pile is controlled to be the minimum value, the head-tail height difference of the conveying belt 33 is reduced, and the power output can be reduced; when the material is reversely fed to the outside through the silo through the reversible conveying device 3, the distance between the blanking point and the belt receiving hopper is controlled to be the minimum value, the head-tail wheel height difference of the reversible conveying device 3 is improved, the power output can be increased, the self-weight descending speed of the material flow is fully utilized to be matched with the belt speed of the conveyor, and the power loss is reduced.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
