Description

Technical Field

[0001] The utility model relates to the technical field of shallow silos, in particular to a device for preventing grain from being broken when entering the center of a shallow silo. Background Art

[0002] In shallow silo grain feeding, to ensure grain safety and quality, and to reduce the workload of unloading, anti-grading and crushing reduction devices and multi-point unloading devices are generally used. Among existing anti-grading and crushing reduction devices, most use a multi-functional center pipe or a multi-functional anti-grading and distributing device.

[0003] The existing central pipe mainly guides the grain to fall to the side by adding branch pipes on the side. Although it can effectively prevent grain breakage and improve feeding uniformity, the grain falling from the branch pipe will still have local conical accumulation. In order to avoid the serious problem of silo deviation, it is usually necessary to add three or more branch pipes for diversion. For example, the existing patent with publication number CN118439423A has more branch pipes, which leads to increased costs and increased difficulty in construction. Based on this, we propose an improved anti-breakage device for grain feeding from the center of a shallow silo. Utility Model Content

[0025] In this embodiment, the lower end face of the mounting ring 18 is fixedly connected to a connecting plate 19, and the other end of the connecting plate 19 is fixedly connected to the outer wall of the diversion pipe 101.

When the central pipe 1 sinks, it can still be stably connected through the hinge 20.

[0026] In this embodiment, a cylinder 12 is fixedly provided on the outer wall of the branch pipe 14 near the diversion pipe 101. The output end of the cylinder 12 passes through the branch pipe 14 and is fixedly connected to a baffle 10. The baffle 10 is slidably provided in the branch pipe 14. The cylinder 12 drives the baffle 10 to move up and down perpendicular to the branch pipe 14, thereby facilitating the opening and closing operations of controlling the flow of grain.

[0027] In this embodiment, the lower end surface of the diverter tube 101 is fixedly connected with a support ring 3 , which is rotatably connected in the material guide tube 102 .
