[0026] See Figure 1-Figure 7 .

[0027] In view of the problems mentioned in the above background technology, the embodiment of the present invention provides a pulverizer for producing biomass fuel to solve the above technical problems. The technical solution is as follows:

[0028] A pulverizer for producing biomass fuel, comprising: a base 110, a pulverizing box 120, an upper hopper 130, a motor 140 and a pulverizing mechanism;

[0029] The crushing box 120 is fixed on the base 110, and the top and bottom of the crushing box 120 are both open structures; the upper hopper 130 is fixed on the top of the crushing box 120;

[0030] The pulverizing mechanism includes a pulverizing roller, an upper pulverizing assembly 160, and a lower pulverizing assembly 170 located in the pulverizing box 120. The upper pulverizing assembly 160 and the lower pulverizing assembly 170 have the same structure and are located on the upper and lower sides of the pulverizing roller, respectively. The upper pulverizing assembly 160 is fixed in the pulverizing box 120, and the lower pulverizing assembly 170 is detachably fixed in the pulverizing box 120.

[0031] The crushing roller includes a crushing cylinder 150 and a plurality of crushing teeth 151 fixed to the crushing cylinder 150 and arranged at intervals along the axial direction of the crushing cylinder 150; the motor 140 is fixed to the crushing box 120, and the main shaft of the motor 140 is fixedly connected to the roller shaft on the crushing cylinder 150;

[0032] The upper crushing assembly 160 includes two groups, and the two groups of upper crushing assemblies 160 are symmetrically fixed on both sides of the inner wall of the crushing box 120. The upper crushing assembly 160 includes an upper fixing plate and an upper crushing tooth plate fixed to the upper fixing plate. The upper crushing tooth plate is provided with a plurality of upper crushing teeth that cooperate with the crushing teeth 151 at intervals. The upper crushing tooth plate is tilted toward the crushing barrel 150.

[0033] The lower crushing assembly 170 includes two groups, and the two groups of lower crushing assemblies 170 are symmetrically fixed on both sides of the inner wall of the crushing box 120. The lower crushing assembly 170 includes a lower fixing plate 171 and a lower crushing tooth plate 172 fixed to the lower fixing plate 171. The lower crushing tooth plate 172 is provided with a plurality of lower crushing teeth that cooperate with the crushing teeth 151 at intervals. The lower crushing tooth plate 172 is tilted toward the crushing barrel 150.

[0034] The lower fixing plate 171 is provided with a threaded hole 171 a , and a screw 180 is inserted into the threaded hole 171 a in the lower fixing plate 171 to detachably fix the lower crushing assembly 170 in the crushing box 120 .

[0035] In this embodiment, the base 110 includes two herringbone-shaped support side panels, which are fixed on both sides of the crushing box 120 .

[0036] In this embodiment, the upper hopper 130 includes an upper hopper 131 with a trumpet-shaped structure and a lower hopper 131 with a square structure fixed to the bottom of the upper hopper 131 .

[0037] The working method of a pulverizer for producing biomass fuel provided by the embodiment of the present utility model is as follows:

[0038] 1. Loading: Biomass materials such as straw and wood waste enter the crushing box 120 through the loading hopper 130;

[0039] 2. Crushing start: The motor 140 starts, driving the crushing roller 150 to rotate;

[0040] 3. Material grabbing and crushing: The crushing teeth 151 grab the biomass during rotation and press it downward. The upper and lower crushing teeth respectively engage with the crushing teeth 151 to crush and grind the material. The design of the upper and lower crushing teeth achieves secondary crushing of the material.

[0041] 4. At the same time, due to the inclined design of the upper and lower crushing tooth plates, the biomass materials are continuously compressed and torn into smaller particles during this process;

[0042] 5. Discharge: The crushed fine particles are discharged through the bottom of the crushing box 120, completing the entire crushing process.

[0043] It should be noted that the pulverizer designed in the present invention is designed to improve pulverizing efficiency by having two pulverizing assemblies, namely, a lower pulverizing assembly 170 is added below the pulverizing rollers. However, sometimes, the material pressed between the upper pulverizing assembly 160 and the lower pulverizing assembly 170 may not be easily sheared and ground by the pulverizing rollers and may become stuck between the upper pulverizing assembly 160 and the lower pulverizing assembly 170, thereby interfering with the normal operation of the pulverizer.

[0044] Therefore, the present invention detachably fixes the lower crushing assembly 170 in the crushing box 120. When materials that are not easily sheared and ground by the crushing rollers are mixed between the upper crushing assembly 160 and the lower crushing assembly 170, the user can remove the screws 180 on the lower crushing assembly 170 that connects to the crushing box 120, and then remove the lower crushing assembly 170 to discharge the materials.

[0045] The embodiment of the present invention provides a pulverizer for producing biomass fuel, which has the following beneficial effects: The present invention designs a pulverizer for producing biomass fuel, which has a simple structural design and can perform secondary pulverization of materials, with high pulverization efficiency.

[0046] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units. They may be located in one place or distributed across multiple network units. Some or all of the modules may be selected based on actual needs to achieve the objectives of this embodiment.

[0047] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements.
