[0002] The recycling technology of agricultural solid waste is an important means to achieve an agricultural circular economy. Among them, the recycling technology of nutrients such as C, N, and P has always been a hot topic of agricultural green technology. The straw pellet extruder is a mechanical device specially used to press agricultural waste such as straw and sawdust into granular products. It is widely used in the fields of biomass energy production and livestock feed processing. For example, the patent application document with the announcement number CN219150038U discloses a production device for biomass pellets. The crushed straw is gradually pressurized by a rotating shaft and a spiral drive blade, so that the material is compressed and extruded under the treatment of the extruder head and the heating box, that is, in a high-pressure and high-temperature environment, to finally form biomass pellets. However, since the biomass pellets are formed in a high-pressure and high-temperature environment, the pellet temperature is high and they must be air-dried before they can be packaged and stored. The labor cost is high and it is not conducive to the mass production of biomass pellets. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: In conjunction with the specification Figure 1-4It can be seen that the present application specifically designs a particle extrusion device for agricultural solid waste treatment, including a biomass particle extruder body 1.

A cold air blowing component is provided above the frame 3. A rake component is provided on one side of the cold air blowing component. The rake claws 21 on the two adjacent groups of rake components are arranged alternately. An inclined conveyor 4 is provided at the outlet end of the belt conveyor 2. The outlet end of the inclined conveyor 4 is connected to an automatic baler 5; the above-mentioned vibrating material guiding mechanism includes a bracket 6, an elastic support, a guide trough 7 and a vibration motor 8. The bracket 6 is provided below the discharge port of the extruder body 1, the elastic support is provided on the bracket 6, the guide trough 7 is provided on the elastic support along the inclined direction, and the vibration motor 8 is installed on the lower side wall of the guide trough 7. The elastic support member includes a support 9, a compression spring 10 and a connecting seat 11. The support 9 is fixed on the bracket 6, and the connecting seat 11 is fixed on the side wall of the guide trough 7. The compression spring 10 is installed on the support 9 and welded to the connecting seat 11. The discharge mechanism of the existing biomass pellet extruder body 1 is improved, and a vibration guide mechanism is provided on one side of the discharge port of the extruder body 1; the extruded high-temperature biomass pellets are evenly put onto the belt conveyor 2 through the vibration guide mechanism, and the high-temperature biomass pellets are moved and transported by the belt conveyor 2. During the transportation process, the rake component rakes the biomass pellets while the air-cooled purge component blows cold air on the surface of the biomass pellets, thereby achieving rapid cooling of the high-temperature pellets during transportation. At the same time, the wind flow can take away excess moisture in the biomass pellets, further improving storage reliability. After air drying and cooling, the biomass pellets are further transported into the automatic packaging machine 5 via the inclined conveyor 4 for packaging. The structure is simple and the degree of automation is high, which can effectively improve the production efficiency of biomass pellets.

[0018] During the specific implementation process, as a preferred setting, the above-mentioned cold air blowing assembly includes a mounting base 12, a fan 13 and a Y-shaped air duct 14. The mounting base 12 is arranged above the frame 3, and the fan 13 is arranged on the mounting base 12. One end of the Y-shaped air duct 14 is connected to the air outlet of the fan 13, and the other two ends are directly opposite the top of the belt conveyor 2. The outlet end of the Y-shaped air duct 14 is provided with a rectangular through groove 15, and the rectangular through groove 15 and the Y-shaped air duct 14 are connected by a flat cone transition section 16. The fan 13 draws in the external air flow through the top, and injects it into the flat cone transition section 16 through the Y-shaped air duct 14, and further blows it toward the high-temperature biomass particles through the rectangular through groove 15, thereby improving the heat dissipation and cooling speed of the biomass particles.

[0019] In the specific implementation process, as a preferred setting, the above-mentioned rake material assembly includes a pillar 17, a cross bar 18, a torsion spring 19 and a connector 20. The pillar 17 is installed at the lower end of the cross beam of the frame 3 by a fixing bolt, the cross bar 18 is fixed between the columns, the torsion spring 19 is sleeved on the cross bar 18 and one end is fixedly connected to the cross bar 18, the connecting block is rotatably sleeved on the cross bar 18 and one end is fixedly connected to the torsion spring 19, and the rake claw 21 is welded on one end of the connecting block along the inclined direction, wherein the lower end of the rake claw 21 is a conical block structure, and the rake claw 2 1 is connected to the connecting block and contacts the biomass particles on the belt conveyor 2, and diverts the biomass particles, so that the biomass particles on the belt conveyor 2 form a plurality of ridges, thereby increasing the heat dissipation area. The setting of the torsion spring 19 can make the connecting block have a downward elastic force, so that the rake claws 21 maintain effective contact with the belt surface of the belt conveyor 2. The rake claws 21 on adjacent rake material assemblies are staggered, which can realize repeated raking of the biomass particles. In combination with the cold air purge assembly, the heat dissipation efficiency can be further improved.
