Description

Technical Field

[0001] The utility model relates to the technical field of crushers of fertilizer production equipment, in particular to a vertical crusher for organic fertilizers. Background Art

[0002] Organic fertilizer production lines utilize modern microbial technology, using livestock and poultry manure as the primary feedstock, with bran, peanut shell powder, and crop straw as supplementary materials. The bacteria and livestock and poultry manure are thoroughly mixed, allowing the microbial strains to inoculate into the manure. The fertilizer is then processed through a series of harmless treatments, including rapid heating, fermentation, composting, and deodorization, using equipment such as dehydrators, compost turners, semi-wet material grinders, horizontal mixers, granulators, dryers, coolers, drum screeners, film coating machines, packaging equipment, and belt conveyors. The resulting bio-organic fertilizer is then processed through a series of harmless treatments, including rapid heating, fermentation, composting, and deodorization. A grinder is a machine that crushes large solid raw materials to the required size and is one of the foundational equipment in an organic fertilizer production line.

[0003] For example, Chinese invention publication CN 218459697 U discloses a vertical pulverizer for producing microbial fertilizers, comprising a bracket, a crushing box fixedly connected to the top of the bracket, a second motor fixedly connected to the bottom of the bracket, a rotating rod fixedly connected to the driving end of the second motor, a partition fixedly connected to the interior of the crushing box, a plurality of filter holes evenly distributed around the interior of the partition, a rotating rod extending through the middle of the partition and fixedly connected to a plurality of slats, the sides of the slats each of which is fixedly connected to a crushing blade, each of which is rotatably connected to the top of the partition. The fertilizer is pulverized multiple times by the first motor, crushing blade, second motor, and crushing blade. The provision of a humidity sensor, controller, and heating wire prevents fertilizer adhesion, achieving the technical effects of efficient pulverization and preventing lumps and adhesion, thereby achieving the technical purpose of improving absorption efficiency and eliminating the need for cleaning.

[0004] However, the invention uses two motors, which has a complex structure. It also lacks a device for screening incompletely crushed fertilizer blocks and completely crushed fertilizer blocks, which can easily lead to some fertilizer blocks still existing in the processed fertilizer, causing unnecessary trouble to the subsequent process.
