Description

Technical Field

[0001] The utility model belongs to the technical field of organic fertilizer production, in particular to a filter for organic fertilizer production. Background Art

[0002] Organic fertilizers, also known as "farmyard manure," are any fertilizer made from organic matter (compounds containing carbon). These include human waste, manure, compost, green manure, cake fertilizer, and biogas fertilizer. They are diverse in variety, widely available, and have a long-lasting effect.

[0003] For example, Chinese patent No. CN219505499U discloses a filter for producing organic fertilizer, comprising a chassis, a bracket fixed to the lower surface of the chassis, a feed pipe fixed to the top of the chassis, a crushing mechanism provided inside the chassis, a filtering mechanism provided inside the chassis, a storage box placed below the chassis, a connecting plate fixed to the left side of the chassis, and a waste bin placed below the connecting plate. The filter for producing organic fertilizer can drive a driving gear to rotate by the cooperation of a motor and a first rotating rod, thereby driving a driven gear runner. The driving gear and the driven gear can be protected by the cooperation of a fixed box and a block to avoid being affected by fertilizer. The block allows fertilizer that falls above the fixed box to slide to the roller. The cooperation of the first roller, the second roller, and the pressing block can crush the organic fertilizer entering the device, fully squeeze out the fertilizer liquid remaining in the organic fertilizer, and improve the utilization rate of the organic fertilizer.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used. For example, due to the large distance between the first roller and the second roller, the fertilizer liquid in the organic fertilizer cannot be completely squeezed out during use, resulting in a waste of resources. In addition, the filter of this device will become clogged after long-term use, and the filter of this device is not easy to replace. In view of this, we propose a filter for organic fertilizer production. Utility Model Content
