Granular fertilizers such as biological fertilizers and organic fertilizers are more and more recognized by farmers' friends because of their advantages such as high nutrient content, less auxiliary components, low hygroscopicity, not easy to agglomerate, and easy storage and application, and gradually become farmers' friends to buy fertilizers At present, the granulators used by manufacturers in China's biological fertilizer and organic fertilizer industries to produce biological fertilizers and organic fertilizers are usually double-roll extrusion granulators.

For example, the Chinese patent with publication number CN201473466U discloses an extruding device of an extruding granulator, the extruding device includes a die plate driven by a power device, and the die plate is provided with a particle forming hole. The mold plate is horizontally arranged at the bottom of a casing; the squeeze roller group is located in a horizontal plane above the mold plate, and there is a gap between the mold plate and the squeeze roll group. The roller set includes at least two extruding rollers, the extruding rollers include a roller shaft and a roller body rotatably mounted on the roller shaft, the roller shaft has a first end and a second end, and the roller shaft has a first end and a second end. The first end protrudes from the outside of the casing and is fixedly mounted on the side wall of the casing, and the second ends of the roller shafts of the at least two extrusion rollers are fixed together.

The roller body of the extrusion roller rotates around its roller axis, and the fine powder material is squeezed and forcibly fed forward when it rotates to the gap between the roller body and the die plate, and is extruded from the particle forming hole on the die plate However, when the roller is used to a certain extent, the roller will wear to a certain extent, resulting in an increase in the distance between the rolling surface of the roller and the grinding disc, resulting in a decrease in the force applied by the roller and the fertilizer in the through hole on the grinding disc. Small, thus affecting the fertilizer extrusion effect.

Utility model content

In view of the deficiencies in the prior art, one of the purposes of this utility model is to provide an extrusion device for an extrusion granulator that can improve the stability of fertilizer extruded by rollers.

In order to achieve the above object, the utility model provides the following technical solutions:

An extrusion device for an extrusion granulator, comprising a base and a cylinder disposed on the base, a flat die disposed in the cylinder for fertilizer molding, at least two flat dies disposed on the upper end surface of the flat die for The rollers used to press the fertilizer into the through hole on the flat die and the rotating assembly connected to the base to drive the rollers to rotate on the flat die, a plurality of the rollers are connected through a roller seat, and the rollers The seat is connected with a central shaft, and the central shaft is connected with the rotating assembly. An adjustment assembly for adjusting the distance between the roller seat and the flat die is arranged between the roller seat and the central shaft. A pelletizing knife for cutting shaped fertilizer is provided on the lower end surface of the mold, and the pelletizing knife is connected with the central shaft.

In this way, when the distance between the roller and the flat die is too large, by adjusting the adjustment assembly, even if the roller seat rotates on the central axis, the distance between the roller and the flat die reaches a predetermined range; When the fertilizer enters the cylinder, it falls to the flat die with the action of gravity. At this time, the multiple rollers on the roller base are driven by the rotating assembly to rotate on the flat die, and the fertilizer is squeezed by the rolling of the rollers. Into the through hole of the flat die, after being extruded by multiple rollers, it protrudes to the lower end of the flat die, and then the strip-shaped fertilizer is cut into shape by a pelletizing knife; it can improve the stability of the roller extruded fertilizer , to achieve fast molding and improve production efficiency.
