Description

Technical Field

[0001] The utility model relates to a shallow round silo lifting and distributing device, belonging to the technical field of grain transportation and storage. Background Art

[0002] Grain silos mainly include shallow silos, vertical silos, steel silos, etc. Due to their high degree of mechanization and small footprint, they have been greatly developed and applied in my country in recent years. In particular, shallow silos are the main type of silos that have been built and are planned to be built. At present, shallow silos basically use the central feeding method. Since the distance between the central discharge port of the shallow silo and the bottom of the silo is high, generally about 25-35 meters, it is inevitable that the grain will be automatically graded (the grain falls freely from top to bottom, and the size, weight, shape, impurities, etc. of the particles form natural stratification) and broken, which seriously affects the quality of the grain and is not conducive to the safe storage of grain. If there is a serious grading of grain, it will affect the effective and uniform ventilation of the grain layer in the silo, resulting in safety concerns such as heating, mildew, germination, and deterioration of materials during the grain storage period. At present, a series of anti-grading and anti-crushing devices and equipment have appeared in China, such as: wall-mounted folding plate anti-crushing device, pressure door umbrella-shaped multi-point distributor, valve-controlled anti-grading device, CNC rotary grain distributor, multi-functional central pressure reducing pipe and other devices and equipment. Although the above devices and equipment can solve the problem of automatic grading and crushing of grain to a certain extent, they all have certain defects, such as unsatisfactory effect, inability to take into account both anti-grading and anti-crushing, or difficult maintenance, or potential safety hazards, such as large dust in the warehouse, which belongs to the dust explosion danger zone. Therefore, the above technical problems still need to be solved. Utility Model Content

The traction rope bypasses the pulley and is limited by a tether ring provided on the lifting material distribution bin. The folding material distribution trough is controlled to be unfolded or closed by manually pulling it up and down. A pointed grain distributor (401) is provided in the lifting material distribution bin. The lifting device (7) is installed on the inner wall of the silo and connected to a steel wire rope, and the other end of the steel wire rope pulls the lifting and distributing bin to rise and fall; the arrangement structure of the steel wire rope is as follows: the other end of the steel wire rope passes around a plurality of fixed pulleys on the inner wall of the top of the silo and then changes direction to reach the top of the lifting and distributing bin vertically downward, first passes around the fixed pulley on one side of the steel wire rope channel pipe (413) and passes through the steel wire rope channel pipe, then passes around the fixed pulley (409) on the other side and then passes vertically upward and is fixed on the inner wall of the top of the silo, forming a rectangular arrangement structure, so that the lifting and distributing bin maintains horizontal lifting.

2. A shallow silo lifting and distributing device as claimed in claim 1, characterized in that: The spherical compensator (2) has flanges at the two ends of the pipe openings, and the interior is connected from top to bottom. The two ends of the spherical compensator (2) are respectively connected to the lower pipe opening of the grain conveying pipe and the upper pipe opening of the telescopic sleeve; the telescopic sleeve (3) is provided with a telescopic dust cover outside.

3. A shallow silo lifting and distributing device as claimed in claim 1, characterized in that: A hook rope (501) and a load-bearing rope (201) are provided on the inner wall of the top of the silo (6); the other end of the load-bearing rope (201) is connected to the bottom flange of the spherical compensator; the hook rope (501) assists in hooking the suspension fixing device (5) of the lifting material distribution silo that rises to the top position to limit the position.

4. A shallow silo lifting and distributing device as claimed in claim 3, characterized in that: The hanging fixture (5) is a ring-shaped handrail structure connected to the top side wall of the lifting material distribution bin; The lifting equipment is a hydraulic winch or a pneumatic winch; The multi-layer sleeves of the telescopic sleeve (3) are arranged as circular, square, and rectangular sleeves; A dust cover is installed outside the telescopic sleeve; The valve is pneumatically controlled.

5. The shallow silo lifting and distributing device according to claim 1, characterized in that: The pointed grain distributor (401) is configured as a conical structure that is concave upward from the bottom of the lifting material distribution bin and protrudes inside the bin, so that an annular pointed bottom is formed between the pointed grain distributor and the bottom of the lifting material distribution bin; a plurality of distributor partitions with triangular tangential cross-sections that are narrow at the top and wide at the bottom are arranged at intervals along the circumference of the annular pointed bottom, dividing the annular pointed bottom area into a plurality of funnel-shaped feed troughs (410) with pointed bottoms, and a discharge port (411) is correspondingly arranged at the bottom of the funnel-shaped feed trough to connect to the feed trough (407) or the short feed pipe (403) for unloading.
