[0031] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] Reference Figures 1 to 6 This utility model proposes a biomass pellet feeding device, comprising:

[0034] The screen housing 11 has an inlet 111 on its upper side and a first outlet 112 and a second outlet 113 on its two sides, respectively.

[0035] The guide cloth 12 is set inside the screen housing 11. The guide cloth 12 is inclined downward towards the second discharge port 113. Compared with the plate, the guide cloth 12 has better extensibility and tension, so that the hammer vibration assembly can more directly impact the raw material on the guide cloth 12, thereby improving the separation effect of the raw material.

[0036] The guide plate 13 and the guide block 14 are provided. The guide plate 13 is disposed between the first discharge port 112 and the guide cloth 12, and the guide block 14 is disposed between the guide cloth 12 and the second discharge port 113.

[0037] A blower assembly 15 is connected to a blower, and the blower assembly 15 is connected inside the screen housing 11;

[0038] The hammer-vibration assembly effectively separates the adhered materials from the surface of the guide cloth 12 by reciprocatingly hammering the raw materials. Since the adhesion of raw materials to the guide cloth 12 usually affects the subsequent separation process, the hammer-vibration assembly uses high-frequency, high-intensity hammering to cause violent vibration and displacement of the raw materials on the surface of the guide cloth 12, quickly breaking up the adhered materials and improving their looseness and flowability. These dispersed materials then combine with the blower assembly 15, where a strong airflow further accelerates the separation of the raw materials from the stones. The blower assembly 15 utilizes the airflow to lift and carry away lightweight biomass raw materials, while denser stones, due to their gravity and higher density, cannot be carried away by the airflow and ultimately fall back to the surface of the guide cloth 12. This combination makes the separation process more efficient, significantly improving the separation effect between biomass raw materials and stones. Finally, the separated raw materials are sent to a crusher to be crushed into biomass pellets, which are then packaged and transported, improving the overall processing efficiency of the biomass pellets. 。

[0039] The hammer-vibration assembly reciprocates and poundes the raw material on the guide cloth 12, rapidly separating the material adhering to the guide cloth 12. Then, in conjunction with the blower assembly 15, the dispersed raw material is quickly separated from the stones. Simultaneously, the hammer-vibration assembly can rapidly pound different areas on the guide cloth 12. Through repeated pounding, the raw material on the surface of the guide cloth 12 is fully loosened and vibrated.

[0040] Reference Figures 2 to 6 The hammer vibration assembly includes several limiting plates 21, each of which is fixedly connected to the inner wall of the screen housing 11. Several receiving plates 22 are slidably connected between two limiting plates 21 on the same side. Each receiving plate 22 is rotatably connected to a linkage plate 23 and a receiving plate 24. A flip plate 25 is rotatably connected to the receiving plate 24. A transmission groove 251 is opened on the flip plate 25. The non-center part of the linkage plate 23 abuts against the inner wall of the transmission groove 251.

[0041] Each receiving plate 22 is rotatably connected to a linkage gear 26 on the side away from the flip plate 25, and the linkage gear 26 is coaxially and fixedly connected to the linkage disk 23.

[0042] A linkage rack 27 is fixedly connected between two limit plates 21 on the same side, and each linkage gear 26 meshes with the adjacent linkage rack 27.

[0043] A drive assembly is used to drive the linkage gear 26 and the linkage rack 27 to rotate relative to each other.

[0044] The drive assembly provides power to move the receiving plate 22, causing the linkage gear 26, which meshes with the linkage rack 27, to rotate. This causes the linkage disk 23, which is coaxially fixed, to rotate. The linkage disk 23, through its non-center contact with the transmission groove 251, causes the flipping plate 25 to swing up and down around the center of the receiving plate 24, thereby causing the flipping plate 25 to pound the guide cloth 12, which in turn causes the raw material on the guide cloth 12 to be quickly shaken apart.

[0045] The drive assembly provides power to the hammer vibration assembly, enabling it to effectively pound the guide cloth 12. This allows for the rapid shaking and separation of raw materials adhering to the guide cloth 12. Furthermore, the drive assembly increases the pounding area of ​​the hammer vibration assembly, resulting in a more uniform force distribution on the guide cloth 12. Through repeated pounding, the raw materials are sufficiently loosened and vibrated on the surface of the guide cloth 12. Especially for materials that are heavily adhered or piled up, pounding allows them to be quickly dispersed, significantly improving the flowability of the raw materials, reducing adhesion between them, and thus improving the separation efficiency between the raw materials and the stones.

[0046] Reference Figures 2 to 3 and Figures 5 to 6 The drive assembly includes two sets of transmission components, each set of transmission components is respectively set between two limit plates 21 on the same side. Each set of transmission components includes a limit post 31, a limit screw 32 and a drive motor 33. The limit screw 32 is rotatably connected between the two limit plates 21 on the same side. The limit post 31 is set on the lower side of the limit screw 32. The drive motor 33 is fixedly connected to one of the limit plates 21. The drive shaft of the drive motor 33 is fixedly connected to one end of the limit screw 32.

[0047] The driving component provides power to drive the reciprocating movement of each receiving plate 22. Through the relative movement of the receiving plates 22, the linkage gear 26 begins to rotate, which in turn drives the tilting plate 25 to pound and compress the guide cloth 12. The pounding action of the tilting plate 25 ensures that the raw material on the guide cloth 12 receives sufficient impact force during its downward movement. This impact force effectively breaks up any adhering raw material, thus promoting rapid dispersion. The reciprocating movement of the receiving plates 22 not only drives the frequent pounding of the tilting plate 25 but also expands the pounding area, making the force distribution on the raw material on the guide cloth 12 more uniform. Through repeated pounding, the raw material is sufficiently loosened and vibrated on the surface of the guide cloth 12. Especially for raw materials that are heavily adhered or piled up, they can be quickly dispersed after pounding, significantly improving the flowability of the raw material, reducing adhesion between raw materials, and thus improving the separation efficiency of the raw material and the stones.

[0048] Reference Figures 2 to 3 and Figures 5 to 6 A hammering column 34 is fixedly connected between the two coaxial flipping plates 25;

[0049] By amplifying the deformation force of the flipping plate 25 on the guide cloth 12 through the hammering column 34, the raw materials on the guide cloth 12 are subjected to a large impact, which enables the adhering raw materials to be separated more quickly. The design of the hammering column 34 effectively improves the flowability of the raw materials and ensures a more ideal separation effect between biomass raw materials and stones. This operation not only improves the separation efficiency, but also effectively prevents the adhering raw materials from affecting the subsequent processing stages.

[0050] Reference Figure 5 and Figure 6 The hammering radius of the hammering column 34 near the feed inlet 111 should be greater than that of the hammering column 34 far from the feed inlet 111.

[0051] Raw materials near the feed inlet 111 often exhibit significant adhesion due to prolonged accumulation or friction during transportation. The guide cloth 12 is pounded by the pounding column 34, which has a larger pounding radius than the lower side. This effectively pounds specific areas of the guide cloth 12, providing a stronger impact force and ensuring that the raw materials on the surface of the guide cloth 12 are sufficiently loosened and dispersed. Especially for raw materials near the feed inlet 111 that are heavily adhered, the guide cloth 12 deforms under the action of the pounding column 34, generating greater fluctuations and vibrations. This deformation makes the position of the raw materials on the guide cloth more unstable, causing them to rise and disperse upwards. This process not only effectively disperses the adhered raw materials but also enhances the movement of the raw materials on the surface of the guide cloth. The raised raw materials are further carried by the airflow, improving the separation effect between the raw materials and the stones. In this way, the dispersion of the raw materials on the guide cloth 12 is significantly improved, allowing the raw materials entering the screen housing 11 to be separated from the stones more quickly and effectively. The design of the 34-stage hammer column effectively improves the flowability of raw materials, ensuring a more ideal separation effect between biomass raw materials and stones. This operation not only improves separation efficiency but also effectively prevents the impact of adhering raw materials on subsequent processing stages.

[0052] Reference Figure 2 and Figures 4 to 5 The blower assembly 15 includes a partition plate 151, on which a blower 152 is fixedly connected. The air outlet of the blower 152 faces the upper surface of the guide fabric 12.

[0053] The hammer-vibration assembly lifts the raw materials from the surface of the guide cloth 12 through vibration. The vibration helps separate the materials that are adhering to each other, with the spacer 151 playing a crucial blocking role. It physically isolates and blocks the lifted materials, preventing them from spilling into areas other than the guide cloth 12, thus improving the material transport efficiency. After the materials are lifted upwards by vibration, they begin to sink under gravity. During this process, the strong airflow generated by the blower 152 further contributes. Due to the higher density of the stones, gravity makes them easily move downwards along the surface of the guide cloth 12. In contrast, biomass raw materials, due to their lighter texture and lower density, are more easily pushed and moved towards the first discharge port 112 by the airflow.

[0054] Reference Figures 2 to Figure 6 Several blowers 153 are fixedly connected inside the screen housing 11. The air outlet of each blower 153 faces the upper surface of the guide cloth 12. Each blower 153 is fixedly connected to the blower 152 through a three-way pipe.

[0055] The coordinated operation of multiple blowers 153 effectively improves the separation of raw materials. First, under the action of the hammer-vibration assembly, the adhered parts of the raw materials on the surface of the guide cloth 12 are broken up, reducing the adhesion between the materials. During this process, the hammer-vibration assembly lifts the raw materials from the surface of the guide cloth 12 through vibration, providing conditions for subsequent dispersion. Then, the dispersed raw materials are rapidly blown towards the first discharge port 112 by the powerful airflow from the multiple blowers 153. Due to the combined operation of the multiple blowers 153, the raw materials can be quickly removed from the guide cloth 12 in a short time, greatly improving the blowing effect. This not only accelerates the separation and conveying speed of the raw materials but also avoids the accumulation problem caused by material adhesion, improving overall work efficiency and system operational stability.
