Description

Technical Field

[0001] This invention relates to the field of solid waste treatment and recycling technology, specifically a green tree crushing and recycling system. Background Technology

[0002] In the process of urban landscaping, trees are pruned, resulting in a large amount of plant debris. In many areas, the disposal methods are still limited to extensive dumping and simple crushing, without achieving resource transformation, which is a huge waste of natural resources. Therefore, developing a technical solution that can crush landscaping waste and achieve high-value resource recycling has an urgent market demand and important environmental significance. Chinese patent discloses an integrated waste recycling and treatment device for landscaping, application number: CN202122825662.0, which can fully crush green waste. However, current tree crushing and recycling systems cannot effectively accommodate the transport of trees of different sizes during the crushing and recycling process. They are prone to jamming, blockage, and idling due to size deviations in the trees to be recycled, resulting in ineffective transport and system damage. In addition, additional electrical equipment is required for screening of debris, and the synchronization is poor. Not only is the disposal of debris carried by the trees to be recycled not guaranteed, but it is also easy to accelerate system wear and affect the purity of the produced wood. Furthermore, it increases crushing costs and is not energy-saving or environmentally friendly. Summary of the Invention

The motor input terminal is electrically connected to the external power supply output terminal.

[0014] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use; 1. Equipped with a floating feeding mechanism, the flexible feeding frame is constructed through the cooperation of suspension, slider, and material roller. With the limiting support of support rods, support plates, hanging boxes, and air cushions, floating feeding can be achieved, which can greatly improve the fit between the material roller and the tree to be crushed and recycled. This is equivalent to achieving dynamic compensation for the size of the tree to be recycled, making up for the size deviation between the trees. While making the material roller fit the tree better, it can provide a more sufficient and stable pushing force for the tree to be recycled. It can ensure that the tree has enough pushing space, which can not only avoid the jamming and blockage caused by the size deviation of the tree, reducing the failure rate in the tree crushing and recycling process, but also effectively avoid the material roller from spinning and slipping due to insufficient fit, ensuring the effectiveness of the tree pushing work, making the feeding work smoother and more stable, adapting to the feeding of trees of different sizes, and improving the effective applicability of tree crushing and recycling work. On the other hand, the system can effectively utilize the dynamic lifting mechanism of the suspension and the elastic support of the air cushion to reverse the rigid compressive force of the trees to be recycled. This not only works in conjunction with the support rods, support plates, and hanging boxes to effectively cause the screen to vibrate at low frequencies, causing lightweight debris such as grass clippings and leaves to detach, effectively ensuring the purity of the crushed and recycled wood, but also works in conjunction with the rotating box, through pipe, rotating wheel, and camshaft to cause the screen to vibrate at high frequencies, effectively removing debris such as gravel and iron filings carried by the trees to be crushed. While further improving the purity of the crushed and recycled wood, this system effectively avoids jamming and wear caused by hard debris, further ensuring the stability and effective service life of the tree crushing and recycling system. Through the combination of the guide box, filter box, air cushion, air duct, check valve, and grid plate, the elastic support force of the air cushion and the rigid compressive force of the trees can be combined to achieve directional airflow transport and traction. It can also work in conjunction with the guide roller and bottom frame to achieve directional collection of debris, improving the debris removal effect while preventing debris from scattering and enhancing environmental friendliness.

[0015] 2. Equipped with an integrated crushing mechanism, the guide seat, crushing roller, screen, and crushing roller work together to form a two-stage linkage crushing mechanism. Combined with the synchronous transmission of the drive wheel, driven wheel, synchronous wheel, connecting wheel, and toothed chain, this not only effectively improves the compatibility between the pushing and crushing of the trees to be recycled, making the connection between the two stages more stable, efficient, timely, and reliable, but also simultaneously enhances the synchronicity and effectiveness of the feeding and crushing operations. This significantly reduces system malfunctions and blockages caused by discontinuous connections, effectively improving the efficiency of tree crushing and recycling while further ensuring the effective service life of the system. Furthermore, the rotational speed and torque of the crushing and crushing rollers can be adaptively adjusted to simultaneously meet the impact force requirements of initial crushing and the shear stress requirements of further crushing, significantly reducing the crushing burden. By combining impeller, filter head, wheel housing, air guide pipe, diversion box, side outlet pipe, connecting pipe, filter screen, and guide groove, a synchronous diversion and conversion structure can be formed. This structure can further convert and utilize the driving force provided by the motor. In addition, the limiting and adjusting functions of the stopper block and lead screw can not only assist in screening the degree of wood pulverization, but also effectively achieve the limited control of the size of the pulverized wood, thereby flexibly meeting the needs of different degrees of wood pulverization, improving the convenience of secondary utilization of pulverized wood, and further enhancing the flexibility and effective applicability of the system. Moreover, it can guide the pulverized wood in a directional manner, avoiding wood blockage and accumulation, preventing debris from scattering everywhere, and at the same time achieving auxiliary cooling, making the pulverization and recycling work more durable and efficient, further ensuring the stability of the system. It can also provide auxiliary wind power drive for the screening of impurities, further improving the screening and removal effect of impurities.

[0016] In summary, this system, during the crushing and recycling of trees, not only enables floating feeding and dynamic compensation for dimensional deviations in the wood to be recycled, improving the compatibility of feeding with wood of different sizes and expanding the system's compatibility and adaptability while enhancing the effectiveness of tree conveying, but also utilizes the hard compressive force exerted by the trees on the system to form a composite screening of high-frequency low-amplitude and low-frequency high-amplitude materials. This effectively removes impurities carried by the trees, reduces system wear, and improves the purity of the produced wood, making tree recycling more environmentally friendly and efficient. Furthermore, it enables two-stage linkage crushing of trees, reducing the crushing burden while flexibly limiting the degree of crushing to meet the processing needs of different specifications, thus expanding its adaptability.

The end face of the screen plate 211 gradually decreases from the guide roller 218 side to the material roller 203 side to improve the compatibility and adaptability of impurity screening with feeding operation. The integrated crushing mechanism 30 includes a guide seat 301; Inside the machine body 1, a guide seat 301 is installed on the other side of the suspension 201.

The input end of motor 305 is electrically connected to the output end of external power supply to achieve synchronous drive and improve the synchronicity of crushing operation.

[0021] The working principle and usage process of this invention: Before crushing and recycling trees, the machine body 1 can be placed in a designated location according to actual needs. During the pruning of garden trees, the machine body 1 can be fixedly placed on an external trailer for mobile recycling of tree branches and trunks. Alternatively, the machine body 1 can be fixedly installed on the ground in a designated location. After collecting the trees to be crushed, the trees to be crushed are crushed and recycled in a centralized manner. After fixing the machine body 1, the material pipe 12 can be rotated and bent to align the pipe opening with the external wood receiving device. Then, the crushing and recycling of wood can begin. During the tree crushing and recycling process, the motor 305 is started first. Under the meshing transmission of the drive wheel 316, driven wheel 317, synchronous wheel 318, connecting wheel 319 and toothed chain 320, each guide roller 218, material roller 203, crushing roller 302 and crushing roller 304 will rotate synchronously. At this time, the tree to be crushed is placed on the guide roller 218. The guide roller 218 will push the tree to be crushed along the screen plate 211 towards the material roller 203 for auxiliary pushing. At the same time, during the rotation of the material roller 203, it will further drag the tree to be crushed and send it into the chamber where the crushing roller 302 is located in the guide seat 301. During this process, as the tree to be crushed comes into contact with the material roller 203, it will simultaneously press against the suspension 201 and the material roller 203 while being dragged by the material roller 203. As a result, the suspension 201 will be pressed down relative to the material roller 203 under the pressure, opening up the gap between the suspension 201 and the material roller 203. This allows the material roller 203 to automatically adapt to the size of the tree during the pushing process of the tree to be crushed. This ensures that the material roller 203 fits the tree more closely, guaranteeing the pushing force while ensuring that the tree gets enough pushing space, making the feeding work smoother and more stable, and adapting to the feeding of trees of different sizes. During this process, under the constraints of slider 202 and support rod 204, support plate 205 remains stationary relative to material roller 203. As suspension 201 presses down, hanging box 206 slides relative to support plate 205. Consequently, the hydraulic fluid inside hanging box 206 is squeezed by support plate 205. Under the pressure of support plate 205, the hydraulic fluid inside hanging box 206 located at the top of support plate 205 enters rotating box 207 through the through pipe 208 at the top of rotating box 207, squeezing the inclined surface of rotating wheel 209 and causing rotating wheel 209 to rotate. Then, it is injected into the space inside hanging box 206 located at the bottom of support plate 205 through the through pipe 208 at the bottom of rotating box 207. Conversely, when hanging box 206 rises relative to support plate 205, hydraulic fluid flows in the opposite direction. Similarly, rotating wheel 209 will rotate under the push of hydraulic fluid. Meanwhile, since the effective pushing area of ​​the support plate 205 is greater than the inclined force area of ​​the roller 209, during the process of the material roller 203 pushing the tree to be crushed, as the suspension 201 moves, the roller 209 will drive the camshaft 210 to rotate at a faster speed than the material roller 203. The camshaft 210 will push the screen plate 211 at a high frequency, causing the screen plate 211 to vibrate with a small amplitude and a high frequency, so that the debris such as gravel and iron filings carried by the tree to be crushed will be shaken off and, during the rolling process along the screen plate 211, pass through the screen plate 211 and fall into the bottom frame 219. Similarly, during the process of pushing the wood to be crushed by the material roller 203, there will always be a size deviation in the wood to be crushed, whether it is different wood or different parts of the same wood. While the wood to be crushed is pressing against the suspension 201, the air cushion 214 will also provide elastic support to the suspension 201 through the hanging box 206, so that the gap between the material roller 203 and the suspension 201 always fits the wood to be crushed and adapts to the size deviation. That is, in this process, under the elastic support of the air cushion 214 and the hard compression of the wood to be crushed, as the material roller 203 rotates, the suspension 201 will rise and fall relative to the material roller 203, causing the screen plate 211 to vibrate with a large amplitude and low frequency, which will cause the light debris such as grass clippings and leaves carried by the wood to be detached. Under the hard pressure of the tree, as the suspension 201 moves back and forth relative to the material roller 203, the air cushion 214 is subjected to reverse pressure while providing elastic support, and thus it will move back and forth. During its contraction, the airflow inside will be compressed. Under the flow restriction guidance of the air duct 215 and check valve 216 on one side, the airflow will pass through the filter box 213 connected to it, enter the guide box 212 on one side of the mesh plate 211, and be discharged along the guide box 212, blowing away the loose grass clippings and leaves and other light debris, and blowing them to the guide box 212 on the other side. During the expansion of the air cushion 214, under the flow-limiting guidance of the air duct 215 and check valve 216 on the other side, it will draw air from the guide box 212 on the other side of the mesh plate 211, causing negative pressure to be generated inside the guide box 212. When light debris such as grass clippings and leaves are blown towards the guide box 212, the negative pressure will further pull them, causing the light debris such as grass clippings and leaves to fall into the guide box 212 and fall into the bottom frame 219 at the bottom. The presence of the filter box 213 can ensure that debris is not sucked into the air cushion 214, ensuring airflow stability. After the wood to be crushed is fed into the chamber where the crushing roller 302 is located inside the guide seat 301, the crushing roller 302 will initially crush the wood to be crushed as it rotates. Under the screening of the screen 303, the wood that has been initially crushed will pass through the screen 303 and fall into the chamber where the crushing roller 304 is located inside the guide seat 301. As the crushing roller 304 rotates, the crushing roller 304 will further crush the wood that has been initially crushed. During this process, under the transmission of the drive wheel 316, driven wheel 317 and toothed chain 320, since the driven wheel 317 is larger than the drive wheel 316, the crushing roller 304 will rotate at a higher speed than the crushing roller 302, while the crushing roller 302 will rotate with a greater torque than the crushing roller 304. This can effectively meet the cutting force requirements of the wood to be crushed during the initial crushing and the speed requirements of the wood after the initial crushing during further crushing, thus achieving two-stage linkage crushing. During the rotation of the crushing roller 304, the impeller 306 rotates synchronously. Under its traction, external air is filtered by the activated carbon inside the filter head 321 and enters the wheel housing 307. It then enters the distribution box 309 through the air guide pipe 308 and then enters the inner cavity of the guide seat 301 through the connecting pipe 310. It passes through the filter screen 311 and is injected into the chamber where the crushing roller 304 is located. The air blows on the crushing roller 304 to cool it down. At the same time, the air blows on the wood that has been further crushed by the crushing roller 304, so that the wood passes through the hopper 11 with the airflow and is sprayed into the external wood receiving device through the material pipe 12. During this process, the rotatable screw 314 drives the plug 313 to slide inside the diversion box 309 to change the relative opening of the flow port of the connecting pipe 310 and the flow port of the side outlet pipe 315, thereby adjusting the air volume sent into the chamber where the crushing roller 304 is located through the connecting pipe 310. According to actual needs, the size of the wood fragments blown out is controlled by the gravity difference between the crushed wood fragments. During the further crushing of the wood by the crushing roller 304, the inner spiral blade and the outer spiral blade on the crushing roller 304 will tear and cut the wood in two directions until the wood is broken to the point that it can be blown by the airflow, thus meeting the needs for different degrees of crushing. The airflow that enters the side outlet pipe 315 through the diversion box 309 will then enter the guide box 212 connected to it, where it will merge with the airflow expelled by the air cushion 214, together blowing away light debris such as grass clippings and leaves, and promoting their separation.
