The high level in the high level conveyor of the present invention is relative to the low level in the low level conveyor, and only represents the high level of the high level conveyor being higher than the low level conveyor.
The use of the packaged grain unpacking system of the present invention will be briefly described by taking the example of transporting packaged grains in a grain cart into a grain bin: when the bulk grain packaging machine is used, an operator stands on the top of the grain conveying vehicle, packaged grains are loaded on the grain conveying vehicle, and the packaged grains are packaging bags filled with bulk grains; the sprocket can rotate clockwise to increase the height of the high-level conveyor and the height of the height adjusting roller is lowered; the chain wheel rotates anticlockwise to reduce the height of the high-level conveyor, and the height of the height adjusting roller rises.
The height of the high-order conveyor is adjusted, so that an operator can easily transport the packaging bags onto the high-order conveyor (the requirement that the discharge end of the high-order conveyor can correspond to the feed inlet of the spiral discharging device is met), the same conveyor belt can ensure that the high-order conveyor is positioned at the corresponding height, and the energy consumption is saved in the height adjustment process of the high-order conveyor. The operator only needs to carry the packaged grain to the left end of the high-order conveyor, the packaged grain is conveyed to the blanking cylinder of the spiral blanking device by the high-order conveyor, then slides to the low-order conveyor from top to bottom along the spiral blade, and is conveyed to the movable conveyor by the low-order conveyor. The arrow direction in fig. 1 indicates the direction of movement of the package.
When the height of the packaged grain on the grain conveying vehicle is reduced to a certain degree, the height of the high-order conveyor is adjusted, and the high-order conveyor and the low-order conveyor share the same conveyor belt.
In other embodiments of the invention: the high-level conveyor and the low-level conveyor do not share the same conveyor belt, and the high-level conveyor and the low-level conveyor respectively use the independent conveyor belts; at this time, the conveyor height adjusting mechanism that realizes the height adjustment of the high-order conveyor may be a lifting mechanism by which the height of the high-order conveyor is lifted.
