Technical Field

[0001] The present invention relates to the technical field of garden wood recycling, and in particular to a device for recycling and converting wood chips for garden maintenance. Background Art

[0002] The recycling and utilization of garden wood is an important way to achieve green recycling. After pruning and cleaning branches and tree trunks are crushed and processed, and then subjected to high-temperature disinfection and crushing and forming treatment, high-quality organic mulch or compost raw materials can be made. The fertilizers converted from these woods are rich in humus, can improve the soil structure and enhance water retention, not only reduce the cost of garden waste treatment, but also provide natural nutrients for plant growth, achieving a win-win situation of ecological and economic benefits.

[0003] In garden maintenance and greening projects, the recycling of wood chips is an important link in realizing resource recycling. There are generally two major technical bottlenecks in existing wood chip recycling devices: First, the crushing system has insufficient adaptability to woods of different specifications. Especially for branches with larger diameters or tree species with harder wood (such as ginkgo and camphor), the blades of traditional single-shaft crushers wear quickly and have insufficient cutting force, resulting in large wood chips remaining after crushing and requiring secondary screening and rework; Second, the shapes of the wood chips after crushing are irregular, with a mixture of powdery and strip-shaped fragments, and the moisture content fluctuates greatly, which cannot directly meet the requirements of compost fermentation for the particle size and uniformity of the materials.

[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0028] The wood chip particle recycling and conversion device for garden maintenance according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] As Figures 1 - 4 shown, the wood chip particle recycling and conversion device for garden maintenance provided by the embodiment of the present invention includes a crushing mechanism 2 and a kneading mechanism 3. Among them, the crushing mechanism 2 includes a crushing box 1, a material guiding plate 21 and a crushing disc 22. A support 12 is arranged at the bottom of the crushing box 1. The crushing disc 22 is rotatably arranged inside the crushing box 1. A crushing tooth 23 is arranged on one end face of the crushing disc 22. The material guiding plate 21 is arranged on the side opposite to the crushing tooth 23.

[0030] The kneading mechanism 3 is arranged at the bottom of the crushing box 1. The kneading mechanism 3 includes a kneading box 33, a kneading spiral shaft 32 and a discharging and forming head 36. Among them, the kneading box 33 is arranged at the bottom of the crushing box 1. The kneading spiral shaft 32 is rotatably arranged inside the kneading box 33. The discharging and forming head 36 is arranged at the discharging end of the kneading box 33.

[0031] Specifically, when the wood chip recycling and conversion device of the present application is in use, first, the wood blocks to be crushed are fed into the crushing box 1. The wood blocks enter the surface of the crushing disk 22 along the guide plate 21 and come into contact with the crushing teeth 23. After the crushing disk 22 rotates, it drives the crushing teeth 23 to rotate, tearing and grinding the wood blocks clamped between the guide plate 21 and the crushing teeth 23, and transporting them downward. Through the uniform tearing of the wood blocks by the crushing teeth 23, the crushed wood materials are made more uniform. Subsequently, the torn wood particles enter the mixing box 33. Then, the mixing screw shaft 32 further crushes and extrudes and mixes the wood particles, and extrudes and shapes them from the discharge forming head 36, which is convenient for later storage and utilization.

[0032] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, a scraping component 25 is arranged below the guide plate 21. The scraping component 25 is used to scrape the residual wood between the crushing teeth 23. The scraping component 25 includes a push rod 251, a push plate 252 and scraping teeth 253. Among them, the push rod 251 is horizontally arranged below the guide plate 21, the push plate 252 is connected to the output shaft of the push rod 251, and the scraping teeth 253 are arranged on one end face of the push plate 252, and the scraping teeth 253 and the crushing teeth 23 are staggered and corresponding to each other.

[0033] Specifically, after the crushing teeth 23 tear the wood blocks, a large amount of wood chips will be stuck between the crushing teeth 23. When the crushing teeth 23 with stuck materials rotate to the staggered position with the scraping teeth 253, the fixed scraping teeth 253 remove the wood chips between the crushing teeth 23, keeping the crushing teeth 23 always clean and ensuring the tearing effect of the crushing teeth 23.

[0034] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, a fixing plate 254 is fixedly arranged at the bottom of the guide plate 21. A material discharging opening 255 is penetrated through the fixing plate 254, and the scraping teeth 253 are slidably adapted to the material discharging opening 255. A feeding opening 11 is arranged above the guide plate 21. The top feeding end of the guide plate 21 is inclined. A chamfer is arranged at the edge part of the crushing disk 22, which is convenient for feeding the wood blocks from the feeding opening 11 into the crushing box 1 and making the wood blocks always in contact with the crushing disk 22.

[0035] Specifically, after the scraping teeth 253 and the crushing teeth 23 are cleaned for a period of time, since the scraping teeth 253 move in one direction relative to the crushing teeth 23, at this time, wood chips will also remain on the surface of the scraping teeth 253. The push rod 251 drives the push plate 252 to move leftward, thereby driving the scraping teeth 253 to slide leftward relative to the material discharging opening 255. The material discharging opening 255 intercepts and cleans the wood chips on the scraping teeth 253, keeping the surface of the scraping teeth 253 clean.

[0036] In one embodiment of the present invention, as Figure 4 shown, a plurality of feeding ports 34 are provided on the kneading box 33, and an extrusion transfer pipe 35 is provided at the output end of the kneading box 33. The output end of the extrusion transfer pipe 35 is connected to the discharging and forming head 36, and the diameter of the extrusion transfer pipe 35 is smaller than that of the kneading box 33.

[0037] Specifically, after the shredded wood particles enter the kneading box 33 and during the kneading and extrusion process by the kneading screw shaft 32, some adhesives or liquid agents for kneading are added through the feeding ports 34, so that the wood particles are more fully mixed, facilitating the kneading and flowing of the wood particles and also facilitating the extrusion molding of the wood particles after mixing. The extruded material after kneading enters the drying box 51 through the extrusion transfer pipe 35.

[0038] In one embodiment of the present invention, as Figure 4 shown, a drying mechanism 5 is provided at the output end of the discharging and forming head 36, including a drying box 51, a blower 52 and a heat baking assembly 58. Among them, the drying box 51 is provided at the output end of the discharging and forming head 36, and a plurality of conveyor belts 57 are provided inside the drying box 51.

[0039] The heat baking assembly 58 is provided at the middle position of the drying box 51. There are two blowers 52, which are respectively located on both sides of the heat baking assembly 58. A wind guiding plate 53 is provided at the bottom of the blower 52, and air discharge ports 54 corresponding to the wind guiding plate 53 up and down are provided on the side wall of the drying box 51.

[0040] Specifically, the extruded material after kneading is extruded into strips through the discharging and forming head 36 and continuously conveyed through the conveyor belt 57. During the conveying process, first, the blower 52 dries the surface of the strip-shaped extruded material, and then it enters the heat baking assembly 58 for baking to harden the kneading agent or adhesive in the strip-shaped extruded material. Subsequently, after the strip-shaped extruded material is discharged from the heat baking assembly 58, it continues to be dried and cooled by the blower 52 to harden the strip-shaped extruded material and prevent the extruded material from becoming loose later.

[0041] In one embodiment of the present invention, as Figure 4 and Figure 6 shown, the heat baking assembly 58 includes a heat insulation pipe 581, a protective inner lining 582 and a heating wire 583. Among them, the heat insulation pipe 581 is provided at the middle position inside the drying box 51, and each conveyor belt 57 passes through a heat insulation pipe 581. The protective inner lining 582 is provided inside the heat insulation pipe 581, and the heating wire 583 is provided inside the protective inner lining 582. The surface of the conveyor belt 57 is a hollow structure, and the cross-section of the conveyor belt 57 is an arc-shaped structure to reduce the deformation of the surface of the extruded material. A material guiding support plate 55 is provided at the bottom of the conveyor belt 57, and the material guiding support plate 55 passes through the heat insulation pipe 581 to prevent the conveyor belt 57 from bending during the conveying process.

[0042] Specifically, after the extruded material enters the hot baking assembly 58, the heating wire 583 is heated, causing the inner side of the heat insulation tube 581 to generate heat, and the heat is transferred to heat the extruded material passing through the inner side of the heat insulation tube 581. The heat insulation tube 581 plays a certain heat preservation role, reducing heat loss during the drying process of the extruded material. The protective inner lining 582 plays a role in protecting the heating wire 583. And since the surface of the conveyor belt 57 is a hollow structure, heat can pass through the bottom of the conveyor belt 57 to heat the extruded material comprehensively.

[0043] In an embodiment of the present invention, as Figure 2 and Figure 4 shown, a conveyor belt driving roller 56 is arranged inside the conveyor belt 57 for driving the conveyor belt 57 to rotate, and a driving roller driving motor 59 for driving the conveyor belt driving roller 56 to rotate is arranged outside the drying box 51.

[0044] In an embodiment of the present invention, as Figure 2 and Figure 4 shown, a granulating mechanism 6 is arranged at the discharging end of the drying box 51, including a discharging head 61 and a rotating cutter head 64. The discharging head 61 is arranged at the discharging end of the drying box 51, a discharging port 62 runs through the inside of the discharging head 61, and a discharging guide plate 65 is arranged at the feeding end of the discharging head 61.

[0045] A granulating motor 63 is arranged on the drying box 51. The output shaft of the granulating motor 63 is connected to the rotating cutter head 64. The rotating cutter head 64 corresponds to the discharging port 62. A receiving trough 4 is arranged below the discharging port 62, and a material sorting bin door 511 is arranged on the drying box 51.

[0046] Specifically, after the extruded material is dried, the dried and hardened extruded material enters the discharging head 61 through the discharging guide plate 65 and is discharged through the discharging port 62. After being discharged, the rotating cutter head 64 is driven to rotate by the granulating motor 63, thereby granulating the dried and hardened extruded material, and finally discharging it into the receiving trough 4.

[0047] In an embodiment of the present invention, as Figure 4 shown, a reduction motor 24 is arranged on the crushing box 1. The power shaft of the reduction motor 24 is connected to the crushing disc 22 for driving the crushing disc 22 to rotate. A mixing driving motor 31 is arranged on the mixing box 33. The mixing driving motor 31 is connected to the mixing spiral shaft 32 for driving the mixing spiral shaft to rotate.

[0048] For the sake of clearly explaining the above embodiments, refer to Figures 1 - 8, the specific working principle of the wood chip granule recycling and conversion device for garden maintenance of the present invention is as follows: When the wood chip granule recycling and conversion device of the present application is in use, first, the wood blocks to be crushed are fed into the crushing box 1 through the feeding port 11. The wood blocks enter the surface of the crushing disk 22 along the guide plate 21 and come into contact with the crushing teeth 23. Subsequently, after the reduction motor 24 drives the crushing disk 22 to rotate, it further drives the crushing teeth 23 to rotate, tearing and grinding the wood blocks clamped between the guide plate 21 and the crushing teeth 23, and transmitting them downward. Through the uniform tearing of the wood blocks by the crushing teeth 23, the crushed wood materials are made more uniform. Subsequently, the torn wood material particles enter the mixing box 33.

[0049] After the crushing teeth 23 tear the wood blocks, a large amount of wood chips will be stuck between the crushing teeth 23. When the crushing teeth 23 with stuck materials rotate to the staggered position with the scraping teeth 253, the fixed scraping teeth 253 remove the wood chips between the crushing teeth 23, keeping the crushing teeth 23 always clean and ensuring the tearing effect of the crushing teeth 23. After the scraping teeth 253 and the crushing teeth 23 are cleaned for a period of time, the push rod 251 drives the push plate 252 to move leftward, thereby driving the scraping teeth 253 to slide leftward relative to the discharge port 255. The discharge port 255 intercepts and cleans the wood chips on the scraping teeth 253, keeping the surface of the scraping teeth 253 clean.

[0050] After the torn wood material particles enter the mixing box 33, during the mixing and extrusion process of the mixing spiral shaft 32, some adhesives or liquid agents for mixing are added through the feeding port 34 to make the wood material particles mix more fully, facilitating the mixing and flowing of the wood material particles and the extrusion molding of the mixed wood material particles. The extruded material after mixing is extruded into strips through the discharge molding head 36 and continuously transported through the conveyor belt 57. During the transportation process, first, the surface of the strip-shaped extruded material is air-dried by the fan 52, and then enters the heat baking component 58 for baking to harden the mixing agent or adhesive in the strip-shaped extruded material. Subsequently, after the strip-shaped extruded material is discharged from the heat baking component 58, it continues to be air-dried and cooled by the fan 52 to harden the strip-shaped extruded material and prevent the subsequent extruded material from being loose.

[0051] After the extruded material is dried, the dried and hardened extruded material enters the discharge head 61 through the discharge guide plate 65 and is discharged through the discharge port 62. After being discharged, the cutting motor 63 drives the rotating cutter head 64 to rotate, thereby cutting the dried and hardened extruded material into particles, which are finally discharged into the receiving tank 4 for convenient storage and utilization in the later stage.

[0052] In summary, the wood chip particle recycling and conversion device for garden maintenance in the embodiments of the present invention is provided with a crushing disk and a feeding plate in the crushing box. The crushing teeth on the surface of the crushing disk are arranged opposite to the feeding plate, continuously frictionally tearing the wood block clamped between the two and transmitting it downward. The crushing teeth evenly tear the wood block, making the crushed wood more uniform. Subsequently, the crushed wood is continuously extruded and transmitted by the mixing spiral shaft in the mixing box and extruded into shape through the discharging and forming head, which is convenient for later storage and utilization.

[0053] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and deformations to the above embodiments within the scope of the present invention.
