Description

Technical Field

[0001] The utility model relates to the technical field of grain silo cleaning, and more specifically, to a bulk grain silo bottom cleaning device. Background Art

[0002] A granary is a special building for storing grain. It is used to store large amounts of grain. In order to ensure the discharge of grain from the granary, a certain slope is generally set at the discharge port of the granary, so that the grain inside the granary can enter the discharge port through its own slope and be discharged. It is then discharged into the scraper conveyor through the discharge port and finally transported by the scraper conveyor.

[0003] After searching, a Chinese patent with patent publication number CN207820562U discloses a grain storage bin for a harvester. The structure drives the screw to rotate through a driving motor, opens the sealing gasket to facilitate the discharge of grain, and can also dry the grain, thereby extending the storage time of the grain. It not only reduces labor intensity, but also improves grain unloading efficiency.

[0004] However, after the existing bulk grain silos are discharged, especially the simple reinforced silos built by enterprises, when the bulk grain scraper conveyor in the middle of the bottom is empty and the bulk grain scraper conveyor cannot pass through its own slope, the bottom of the silo can only be cleaned by manually entering the interior of the silo, which increases the labor burden. In view of this, the utility model proposes a bulk grain silo bottom cleaning device. Utility Model Content

[0010] In order to be able to adjust the inclination angle of the shovel plate according to the inclination slope of the bottom of the granary, so that the shovel plate can better fit the surface of the inclined slope of the grain, preferably, a concave block is provided at the bottom of the threaded barrel, a movable block is provided inside the concave block, an axle pin is provided between the concave block and the movable block, and they are movably connected through the axle pin, a locking nut is installed on the outside of the axle pin, the movable block is fixedly installed on the top of the shovel plate, and the locking nut is threadedly connected to the axle pin.

The electric push rod drives the scraper to extend and retract, and the grain at the bottom edge of the granary can be collected and discharged at the exit of the granary, thereby avoiding the burden of manual entry into the granary for cleaning;

[0013] 2. Multiple balls rotate inside the corresponding circular grooves, so that the outer ring fits against the inner wall of the granary during rotation, which can reduce the friction between the outer ring and the inner wall of the granary, thereby ensuring that the outer ring rotates at a uniform speed. The rotation of the outer ring can provide good support for the rotation of the column;

[0014] 3. By rotating the threaded column to make it rotate through the bearing, the thread of the threaded column can be rotated to the inside of the threaded barrel, so as to achieve the effect of connecting and disassembling the shovel plate and the electric push rod, which makes it convenient for operators to replace the worn shovel plate;
