Description

Technical Field

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

[0002] Organic fertilizers are made from various animal waste and plant residues through a certain processing technique to eliminate harmful substances. They are rich in a large number of beneficial substances and can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect and less pollution. They can improve the physical and chemical properties and biological activity of the soil and are the main nutrient for green food production.

[0003] In the production of organic fertilizers, in order to meet the production process requirements, organic fertilizers need to be made into granules before they can be packaged and used, thus the granulation device appeared.

[0004] A Chinese patent with prior art publication number CN219615493U discloses a granulating device for producing organic fertilizers, which feeds the raw materials into the interior of the housing through a feeding hopper, then starts the cylinder to push the push plate downward, and then cooperates with the baffle plate to compact the raw materials between the baffle plate and the push plate, then starts the servo motor, and then the servo motor drives the first rotating shaft to rotate, and under the limit of the U-shaped frame, the baffle plate moves to the right, so that the compacted raw materials fall into the forming hole, and then starts the cylinder to push the push plate downward, so that the compacted raw materials pass through the forming hole to form strips. When the extruded length is appropriate, the cylinder is stopped at this time, and then the rotating motor is started, and then the rotating motor drives the blade to rotate through the second rotating shaft, so that the extruded raw materials are cut into particles, and then the above operations are repeated to complete the granulation operation.

[0005] Although the above patent can make the strip-shaped raw materials extruded from the forming hole compact, so that the cut particles are full and of good quality, it uses a rotating motor to drive the blade to rotate to cut the raw materials into particles, which can easily knock the cut particles away, causing a small part of the fertilizer to be scattered around the granulation device, which is inconvenient to collect and causes a waste of fertilizer. In addition, the raw materials are often not mixed evenly before granulation, which will affect the subsequent granulation process.

[0006] Therefore, the applicant proposed a granulating device for producing organic fertilizer to solve the above problems. Utility Model Content

The mixed raw materials enter the granulation chamber through the connecting pipe.

[0055] Working principle: When in use, the raw material of organic fertilizer is put into the mixing chamber 2 through the feed hopper 5, and the first motor 61 is started. The first motor 61 drives the first rotating shaft 62 to rotate, and the first rotating shaft 62 drives the stirring rod 63 to rotate, and the raw material is stirred again, so that the raw material is mixed more evenly, which provides a good foundation for subsequent processing. After the stirring is completed, the connecting pipe 4 is opened, and the raw material enters the granulation chamber 3 through the connecting pipe 4, and then the connecting pipe 4 is closed, and the pressing plate 72 is driven downward by the cylinder 71 to squeeze the raw material. Through the design of the baffle 83, it can The raw materials above the baffle 83 are pressed by the pressing plate 72, and then the second motor 85 is started, and the second motor 85 drives the second rotating shaft 86 to rotate, thereby driving the active bevel gear 87 to rotate, and the active bevel gear 87 drives the driven bevel gear 88 to rotate, thereby driving the threaded rod 82 to rotate, thereby driving the baffle 83 to move into the interior of the U-shaped frame 81, so that the pressed raw materials can fall into the granulation hole 12, and then the strip raw materials extruded from the granulation hole 12 can be compacted by the pressing plate 72, and at the same time, the raw materials can be put into the mixing bowl through the feed hopper 5. In the mixing chamber 2, the first rotating shaft 62 and the stirring rod 63 are always in the process of rotation, so that the cam 11 is always in rotation. Through the intermittent contact between the cam 11 and the contact plate 95, when the cam 11 is not in contact with the contact plate 95, the cutting hole 94 on the cutting plate 93 completely overlaps with the granulation hole 12, and the raw material is extruded through the granulation hole 12 and the cutting hole 94. When the cam 11 contacts the contact plate 95, the contact plate 95 is first driven to move, thereby driving the connecting rod 92 and the cutting plate 93 to move, so that the cutting hole 94 on the cutting plate 93 will pass through the cutting hole The extruded raw material 94 is cut, and the cut raw material particles fall out of the discharge pipe 10. Then, under the elastic force of the spring 96, the cutting plate 93 returns to the state where the cutting hole 94 and the granulation hole 12 are completely overlapped. The cam 11 drives the cutting plate 93 to reciprocate, so that the granulation effect is better and the production efficiency is higher, and the cut raw material particles are prevented from being knocked away, causing a small part of the fertilizer to be scattered around the granulation device, which is inconvenient to collect and causes waste of fertilizer. The cut raw material particles fall out of the discharge pipe 10 and are collected by the collection box 13.
