[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0040] like Figure 1-5 As shown, this utility model provides a garden biomass energy recovery device, including: a feeding box 1, a conveyor belt 2, and a screener 3;

[0041] The feeding box 1 is located on one side of the screener 3. A conveyor belt 2 is provided between the feeding box 1 and the screener 3. The feeding box 1, the conveyor belt 2 and the screener 3 constitute the basic link for material transmission and processing.

[0042] The feeding box 1 includes: a support frame 13, which is the core frame of the feeding box 1 and provides solid physical support for the feeding box 1. The support frame 13 is a hollow rectangular structure. At least two pressure rollers 15 are provided in the support frame 13. Each pressure roller 15 is provided with a pressure roller drive motor 16 on one side. The bottom of the feeding box 1 is provided with a feeding box outlet, which is connected to the input end of the conveyor belt 2.

[0043] The at least two pressure rollers 15 are evenly and parallelly arranged, with both ends of the pressure rollers 15 embedded in the support frame 13. A bearing is provided between the pressure rollers 15 and the support frame 13. The bearing enables the pressure rollers 15 to rotate smoothly under the drive of the drive motor 16, while effectively reducing wear and ensuring long-term stable operation of the equipment.

[0044] The pressure roller drive motor 16 is fixed to the outer wall of the bearing frame 13. The output end of the pressure roller drive motor 16 is fixedly connected to the pressure roller 15. The pressure roller drive motor 16 provides power to the pressure roller 15. When the material is put into the feeding box 1, the pressure roller 15 operates in coordination under the drive of the pressure roller drive motor 16 to perform preliminary compression and dispersion of the material. This pretreatment can break the agglomeration and compaction of the material, allowing the material to be output from the discharge port at the bottom of the feeding box in a uniform and loose state, avoiding the obstruction of discharge due to material accumulation, and laying the foundation for the smooth conveying of materials by the conveyor belt 2.

[0045] The pressure roller 15 has a cylindrical structure, and its surface is uniformly provided with anti-slip protrusions or corrugated structures. These anti-slip protrusions or corrugated structures are evenly distributed along the axial direction of the pressure roller 15. These anti-slip protrusions or corrugated structures enhance the gripping force of the pressure roller 15 on the material. Regardless of whether the material is granular, blocky, or has a certain degree of stickiness, these anti-slip protrusions or corrugated structures can effectively prevent the material from slipping or falling on the surface of the pressure roller 15, ensuring that the material is conveyed to the discharge port at a stable speed and flow rate, and finally smoothly arrives at the screener 3 via the conveyor belt 2.

[0046] The lower end of the support frame 13 is evenly provided with several telescopic support legs 14. Each telescopic support leg 14 has a rectangular structure and is slidably connected to the support frame 13. The telescopic support legs 14 can flexibly adjust the overall height of the feeding box 1 according to the actual installation environment's ground flatness, equipment docking height, and other requirements. Each telescopic support leg 14 is equipped with a locking post, which can quickly fix the telescopic support leg 14 into a rigid support structure after height adjustment, effectively resisting the vibration reaction force generated by the rotation of the pressure roller 15 during equipment operation and preventing the telescopic support legs 14 from collapsing during operation. To prevent displacement or loosening, and to ensure the stable posture of the feeding box 1 during high-frequency material handling operations, the lower end of the telescopic support leg 14 is equipped with rubber anti-vibration feet. This adds a flexible buffer function to the rigid support, reducing the transmission of vibration to the ground. This reduces equipment noise and avoids interference from vibration to surrounding precision instruments or structural components. The anti-slip properties of the rubber material enhance the adhesion of the feeding box 1 to smooth or uneven ground, preventing the equipment from sliding or tipping over under heavy load or high-frequency vibration conditions. This provides a reliable guarantee for the safety and continuity of the entire material handling process.

[0047] It should be noted that, under normal circumstances, there are two pressure rollers 15, which are arranged in parallel and spaced apart. There are four telescopic support legs 14, which are evenly arranged at the four corners of the support frame 13.

[0048] The bottom of the feeding box 1 is provided with a feeding box outlet, the feeding box 1 outlet is precisely connected to the input end of the conveyor belt 2, and the output end of the conveyor belt 2 is located at the upper end of the screener 3.

[0049] The screening device 3 includes a separation box 7, a screen 10, and a frame 4. The separation box 7 adopts an inclined hollow rectangular structure, which together with the detachable screen 10 forms an efficient material classification space. The screen 10 divides the separation box 7 into upper and lower chambers. Its detachable design makes it easy to quickly change the specifications of the screen 10 according to different material characteristics, flexibly adapting to diverse screening needs. When the material falls from the conveyor belt 2 into the upper chamber of the separation box 7, the vibrators 9 evenly distributed on the outer wall of the separation box 7 generate high-frequency vibration under the drive of the vibrator motor 8, which causes the material to be fully dispersed and rolled on the screen, realizing effective separation between particles. Small particles pass through the screen and fall into the lower chamber, while larger particles slide along the inclined screen 10 to the lower side, forming an automatic diversion of materials of different particle sizes.

[0050] The springs 6 at the four corners of the top surface of the frame 4 absorb and buffer the impact force in real time during the vibration of the sorting box 7. This not only avoids structural damage to the main body of the frame 4 caused by strong vibration, but also maintains the stable amplitude of the sorting box 7 through elastic rebound, ensuring the continuity and uniformity of the screening process. This rigid-flexible design allows the sorting box 7 to maintain a precise tilt angle during high-frequency vibration, so that the material always moves along the preset trajectory towards the first and second discharge ports 11 and the second discharge port 12. Large particles are discharged from the first discharge port 11 in the upper chamber, while fine particles are output from the second discharge port 12 in the lower chamber, realizing efficient sorting of materials of different specifications.

[0051] The top of the frame 4 is equipped with a protective railing 5 that vertically surrounds the outside of the sorting box. The frame 4 is equipped with a climbing ladder, which allows workers to stand on the frame 4 to maintain the vibrator 9 located on the outside of the sorting box 7. The vibrator motor 8 drives the vibrator 9 through a belt drive system. This power transmission method ensures stable vibration frequency while facilitating later maintenance and component replacement, ensuring that the entire screening system maintains a high-efficiency and reliable working state for a long time.

[0052] The garden biomass energy recovery device also includes several arch mounting seats 17 and several dryers 18. The arch mounting seats 17 are fixed to the outer walls of both sides of the conveyor belt 2 in a symmetrical clamping manner. Its unique arch-shaped structure not only provides a stable mounting carrier for the dryers 18, but also cleverly avoids the operating area of ​​the conveyor belt 2, ensuring that material transmission and drying are carried out simultaneously without interference. This clamping design ensures installation accuracy while facilitating quick adjustment of the installation position or disassembly and maintenance according to production needs, providing structural protection for the flexibility and maintainability of the equipment.

[0053] A number of dryers 18, matching the number of arch mounting bases 17, are mounted on the top of the arch mounting bases 17, forming a drying channel covering the full width of the conveyor belt 2. When the wet material passes under the arch mounting bases 17 with the conveyor belt 2, the dryers 18 continuously release uniform heat to dynamically dry the material on the conveyor belt 2. This design effectively solves the problem of wet material easily clumping and adhering to the conveyor belt 2, ensuring that the material enters the screener 3 in a loose and dry state, improving the subsequent screening efficiency and avoiding screen blockage.

[0054] The following is a detailed description of the actual working scenario of a garden biomass energy recovery device.

[0055] In actual work, biomass waste generated from garden maintenance is put into the feeding box 1. The four telescopic legs 14 at the bottom of the support frame 13 are stably supported on the ground by rubber anti-vibration feet. The operator adjusts the height of the legs according to the height of the conveyor belt 2. After the locking column is fixed, a rigid support is formed to ensure that the discharge port of the feeding box 1 is accurately connected to the input end of the conveyor belt.

[0056] After the material falls into the feeding box 1, the two pressure roller drive motors 16 start synchronously, driving the two parallel pressure rollers 15 to rotate in opposite directions. The anti-slip corrugated structure on the surface of the pressure rollers 15 tightly grips the material. Through squeezing and rubbing, the material is broken up by removing the tangled branches and clumped leaves, and the blocky and bundled materials are initially crushed. Under the action of gravity, the crushed material falls evenly from the bottom outlet of the feeding box 1 to the conveyor belt 2, forming a continuous material flow.

[0057] The conveyor belt 2 runs at a constant speed toward the screener 3. When the material passes under the arch mounting seat 17 with the conveyor belt 2, the top dryer 18 is turned on simultaneously. The hot air released by the dryer 18 evenly covers the full width of the conveyor belt 2 to dry the wet material in real time.

[0058] Material falls from the end of conveyor belt 2 into the upper chamber of the separating box 7. At this time, the vibrator motor 8 drives the vibrators 9 on both sides through belt drive to generate high frequency vibration. The separating box 7 forms a stable amplitude under the elastic support of spring 6, which causes the material to roll forward on the surface of screen 10. Fine particles smaller than the screen holes pass through screen 10 and fall into the lower chamber, sliding along the inclined separating box 7 to the lower second discharge port 12. Coarse particles larger than the screen holes move along screen 10 to the first discharge port 11 in the upper chamber, realizing the automatic separation of coarse and fine materials.

[0059] In actual operation, the pressure roller 15 set in the feeding box 1 does not easily crush the metal and rubber products, but will deform them. The overall volume of the metal and rubber products will not decrease and they will easily pass through the sieve holes of the screen 10, thereby achieving the separation of metal and rubber products from easily crushable items such as soil and plants.

[0060] It is understood that the above-mentioned embodiments mentioned in this utility model can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this utility model will not elaborate further.

[0061] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0062] The present invention provides a garden biomass energy recovery device, which can crush the input garden biomass by means of at least two pressure rollers 15 and pressure roller drive motor 16 set in the feeding box 1, so as to facilitate subsequent processing and improve material processing efficiency.

[0063] The feeding box 1 is connected to the conveyor belt 2 through the bottom discharge port. The conveyor belt 2 transports the crushed material to the upper end of the screener 3, realizing the automated material transfer and reducing manual operation.

[0064] The outer wall of the separating box 7 of the screener 3 is equipped with a vibrator 9 and a vibrator motor 8. Together with the spring 6 on the top support of the frame 4, the material can be fully screened on the screen 10 through vibration, thereby improving the screening effect. The screen 10 and the separating box 7 are detachable for easy cleaning and replacement, ensuring the continuity of the screening function.

[0065] By separating the first discharge port 11 and the second discharge port 12 of the separation box 7, materials of different particle sizes after screening can be collected in layers, realizing the effective classification and recycling of biomass, improving resource utilization, and thus achieving the goal of efficient recycling of garden biomass energy.
