Abstract
Description
Technical Field
[0001] This utility model relates to a grain storage silo gate, and more particularly to an automatic alignment grain storage silo gate. Background Technology
[0002] Grain storage silos include tall, flat silos, shallow round silos, and vertical silos. Regardless of the type, all silo entrances are equipped with grain-blocking doors to separate the grain inside and withstand the lateral pressure generated by the accumulation of grain. Currently, triangular and arc-shaped grain-blocking doors are widely used. However, because these doors bear a large load and each door panel is relatively heavy, it is difficult for the left and right panels to align properly when closed, posing a safety hazard. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an automatic alignment grain gate for a grain silo, including a left grain gate and a right grain gate mounted on a support column. The left and right grain gates are movably connected to the left and right support columns in sequence via hinges. The second left and right grain gates from bottom to top are provided with upper grain outlets, and the bottom left and right grain gates are provided with lower grain outlets. The left and right grain gates are locked by a rotary locking mechanism.
[0004] The left-side grain-blocking door includes a frame I and a panel I. The two panels I cover the front and back sides of the frame I, and an aligning cone is provided on the right side of the frame I.
[0005] The right-side grain-blocking door includes a frame II and a panel II. The two panels II cover the front and rear sides of the frame II. The left side of the frame II is provided with an alignment hole corresponding to the alignment cone.
[0006] The upper grain outlet includes a base plate, a connecting plate, a discharge pipe, a gate, and a hinge buckle. The base plate is fixed to the opening of the grain gate, and the discharge pipe is fixed to the base plate through the connecting plate. The discharge pipe has a gap, and a hinge buckle is provided on the edge of the gap. The hinge buckle is movably connected to the gate.
[0007] The lower grain outlet includes a surrounding panel and a door panel. The surrounding panel is fixed to the opening of the grain gate, and the door panel is movably connected to the surrounding panel.
[0008] The rotary locking mechanism includes a lever seat, a lever, and a handwheel. The lever seat is fixed to the left and right grain blocking doors respectively, and the lever seat is movably connected to the handwheel through the lever.
[0009] Compared with the prior art, this utility model has the following advantages: the structure of this utility model is simple and convenient to use. It can be locked after being closed to avoid misalignment of the left and right panels and improve the reliability and safety of the grain blocking door. Attached Figure Description

Detailed Implementation
[0019] like Figures 1-7An automatic alignment grain gate for a grain silo includes mounting columns 2, a left grain gate 3, and a right grain gate 4. The left and right grain gates 3 and 4 are movably connected to the left and right mounting columns 2 respectively via hinges 5. The second left and right grain gates 3 and 4 from bottom to top have upper grain outlets 6, the height of which is adapted to the feed inlet of the grain receiving equipment. The lowest left and right grain gates 3 and 4 have lower grain outlets 7. The left and right grain gates 3 and 4 are locked by a rotary locking mechanism 8 to secure the left and right grain gates. The left grain gate 3 includes a frame I 3.1 and two panels I 3.2, which cover the front and back sides of the frame I 3.1. An alignment cone 3.3 is provided on the right side of the frame I 3.1. The right-side grain-blocking gate 4 includes a frame II 4.1 and two panels II 4.2. The two panels II 4.2 cover the front and rear sides of the frame II 4.1. The left side of the frame II 4.1 has an alignment hole 4.3 corresponding to the alignment cone 3.3. The upper grain outlet 6 includes a base plate 6.1, a connecting plate 6.2, a discharge pipe 6.3, a gate 6.4, and a hinge buckle 6.5. The base plate 6.1 is fixed to the opening of the grain-blocking gate. The discharge pipe 6.3 is fixed to the base plate 6.1 through the connecting plate 6.2. The discharge pipe 6.3 has a slit, and the edge of the slit is provided with a hinge buckle 6.5. The hinge buckle 6.5 is movably connected to the gate 6.4. Lifting or pressing the handle of the gate 6.4 can open or close the discharge outlet. The lower grain outlet 7 includes a surrounding plate 7.1 and a door panel 7.2. The surrounding plate 7.1 is fixed to the opening of the grain-blocking gate, and the door panel 7.2 is movably connected to the surrounding plate 7.1 to realize the opening and closing functions. The rotary locking mechanism 8 includes a lever seat 8.1, a lever 8.2, and a handwheel 8.3. The lever seat 8.1 is fixed to the left grain gate 3 and the right grain gate 4 respectively. The lever seat 8.1 is movably connected to the handwheel 8.3 through the lever 8.2. The threads of the left and right levers are in opposite directions, and the thread direction of the handwheel 8.3 is adapted accordingly.
[0020] When grain is being loaded into the silo, the left and right grain blocking doors 3 and 4 are closed sequentially from the bottom according to the grain level. Alternatively, the left and right grain blocking doors 3 and 4 can be closed in advance. When the left and right grain blocking doors 3 and 4 are about to touch, they are automatically aligned by the alignment cone 3.3 and alignment hole 4.3 of the frame I 3.1. After the left and right doors are aligned and closed, the left and right doors are locked by the rotary locking mechanism 8.
[0021] When discharging grain, the gate 6.4 is lifted, and the grain in the silo flows through the discharge pipe 6.3 to the conveying equipment outside the conveying silo. When the grain level in the silo is lower than the lower grain outlet 7, the locking mechanism 8 is loosened, thereby opening the grain blocking door.
[0022] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
