Description

Technical Field

[0001] The utility model relates to the technical field of granulators, specifically an agricultural waste biomass forming granulator. Background Art

[0002] Biomass fuel refers to compressing agricultural and forestry waste such as straw, weeds, wood chips, shrub branches, and even fruit peels into high-density combustion particles. These agricultural and forestry waste have a high calorific value and are a clean energy resource. In the prior art, a biomass granulator is used to make these renewable biomass fuels into particles for convenient later use. For example, in the utility model patent with the name "A fuel particle forming device for a biomass pellet stove" and the publication number "CN217527387U", it includes a forming tank. An extrusion assembly for extruding the biomass raw materials into shape is arranged in the forming tank. A cutting assembly for cutting the formed biomass raw materials is arranged on the extrusion assembly. A vibration screening assembly for efficiently separating the finished particles and scraps is also arranged in the forming tank. A return material assembly for returning the screened scraps back into the forming tank for extrusion and forming is arranged on the forming mystery. However, this device only rolls the raw materials through a rolling roller, causing the raw materials to fall through the forming holes, and cannot increase the density of the formed biomass particles to maintain a stable shape. The formed biomass particles are easily broken and damaged.

[0003] In the published Chinese patent application with the publication number: CN219682443U and the patent name: "A forming device for biomass particles", it includes: a barrel, with discharge ports for discharging material symmetrically opened on the outer wall; a rotating shaft, arranged inside the barrel, and a spiral conveying blade is installed on the surface; a discharge block, installed on the outer surface of one end of the barrel; a number of discharge holes, symmetrically opened in the discharge block and communicating with the discharge ports; a pair of baffles, symmetrically arranged in the discharge block; and a driving mechanism for driving the pair of baffles to slide is arranged on the barrel. In this prior art, the driving mechanism drives the baffles to reciprocally slide in the discharge block, which can intermittently block and isolate the discharge holes. When blocking and isolating, it can prevent the raw materials in the discharge holes from flowing out. At the same time, under the conveying and extrusion action of the rotating shaft and the screw conveying blade, the density of the raw materials in the discharge holes can be increased, making the shape of the formed raw material particles more stable and preventing breakage. When the baffle slides to open the discharge hole, it is convenient for the formed particles to flow out. At the same time, the reciprocating sliding of the baffle can cut the biomass particles in the discharge hole, making the length of the produced biomass particles the same, which brings convenience to people.

[0004] Although the prior art can solve the above problems, the prior art has certain limitations in the specific implementation process. In the specific implementation process, a separate motor is used to drive the baffle to move, and the baffle opens or closes the discharge port during the reciprocating movement; a single baffle opens or closes multiple discharge ports. When the baffle moves from left to the rightmost side, the material discharged from the discharge port from left to right becomes shorter. When the baffle moves from the rightmost side to the left, the baffle first cuts off the short granular material on the left, and then gradually cuts off the long granular material on the right, resulting in inconsistent lengths of the granular materials. The problems with the prior art are: 1. A separate motor is used to drive the baffle to move, which increases the equipment cost; 2. When a single baffle cuts off multiple discharge ports by moving, the lengths of the formed granular materials vary greatly. Utility Model Content

The feeding component is in transmission connection with the forming component, and the feeding component drives the forming component to slide and displace in the chute 8.

[0031] Among them, the feeding component pushes the materials to move in the material box 1, and the materials are discharged through each discharge hole 4 under the push. The discharge holes 4 are used to discharge pellet materials. The functions of the cutting knife 6 are: one is to cut off the pellet materials discharged from the discharge holes 4 through sliding displacement; the other is that when the cutting knife 6 moves to the discharge holes 4, the cutting knife 6 causes blockage and clogging of the discharge holes 4, and the materials are squeezed in the discharge holes 4, so that the materials are more compact and the density of the materials in the discharge holes 4 is increased.

[0032] Among them, by arranging each cutting knife 6 horizontally, there is a column of discharge holes 4 between two adjacent cutting knives 6.
