Description

Large granule urea loading attachment Technical Field The invention relates to the field of urea processing, in particular to a large-particle urea feeding device. Background In the chemical fertilizer production and storage and transportation links, the problems of large particle size, poor fluidity, material accumulation, material blockage and the like of the traditional feeding equipment are easy to occur, the conveying efficiency is influenced, equipment abrasion and shutdown faults are easy to cause, the traditional bucket type lifting equipment is designed for small particle materials, the hopper structure is not stable enough, the disassembly and maintenance are inconvenient, and the material arrangement structure adapting to the large particle urea is lacking, so that the continuous and stable feeding requirements are difficult to meet, and therefore, the invention provides the high-efficiency feeding device adapting to the large particle urea characteristics. Disclosure of Invention In order to solve the problems, the invention provides a large-particle urea feeding device. The invention provides a large-particle urea feeding device which adopts the following technical scheme: the large-particle urea feeding device comprises a storage tank for placing urea, wherein a feeding structure is arranged above the storage tank, the feeding structure comprises a chain with a loop structure, a plurality of evenly distributed hoppers are arranged on the outer side of the chain, and the hoppers are used for conveying urea in the storage tank upwards; The inside of the storage box is also provided with a material arranging groove, and the height of the side wall of the material arranging groove is gradually reduced along the displacement direction of the hopper. Preferably, the material arranging groove is provided with two side walls, and the width of the two side walls is larger than the diameter of the hopper. Preferably, the inside of the chain is provided with two chain wheels which are respectively arranged at the position close to the storage box and the position far away from the storage box, the two chain wheels are positioned on the same vertical line, and the outside of the two chain wheels is also provided with a vertical plate for fixing the position of the two chain wheels. Preferably, the vertical plate and the external structure are fixed to ensure the stable position of the feeding structure. Preferably, the rotating shaft of the chain is fixedly connected with a coaxial connecting rod, and the end part of the connecting rod is provided with a thread groove, so that the hopper can be additionally installed subsequently. Preferably, a supporting rod is welded on the outer wall of the connecting rod, and the end part of the supporting rod is fixed with the hopper. Preferably, the opening orientation of each hopper is uniform clockwise or uniform anticlockwise, and the rotation direction of the chain is kept consistent.
