Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a crushing device for scrapped wind turbine blades. Background Technology

[0002] Wind turbine blades contain a large amount of metal material, so after they are scrapped, they can be crushed by a crushing device and then recycled. According to existing technology, such as the crushing device for scrapped wind turbine blades disclosed in Chinese patent document CN217774250U, the technical solution disclosed uses the cooperation of a motor, a protective column, a fixing rod, a first crushing tooth column, a second crushing tooth column, a first crushing tooth plate, and a second crushing tooth plate to ensure that the device can repeatedly crush the material, thereby avoiding the waste of material resources, improving the efficiency of the device, and ensuring the effectiveness of the device.

[0003] According to its publicly available technical solutions, existing crushing devices for scrapped wind turbine blades directly feed a large number of pre-cut wind turbine blades from the top into the crusher to complete the crushing process. However, this solution requires cutting large-volume wind turbine blades into smaller sizes in the early stages to facilitate the subsequent feeding process. Therefore, the pre-processing is difficult, the processing steps are complicated, and the final crushed size of conventional crushing devices varies greatly, making it difficult to accurately control the degree of crushing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crushing device for scrap wind turbine blades to solve the problems mentioned in the background technology. This utility model reduces the cutting requirements of scrap wind turbine blades in the early stage, simplifies the pre-treatment process, improves the conveying efficiency, and can make the crushing degree more uniform and the crushing size more precisely controlled.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a crushing device for scrapped wind turbine blades, comprising a crushing device body, the crushing device body including a processing table, a discharge box, a pushing mechanism and a crushing mechanism, a crushing groove being provided at one end of the processing table, a discharge box being integrally formed at the bottom of the crushing groove, a crushing component being detachably mounted on the top of the crushing groove, a pushing mechanism being installed on the surface of the processing table, a first pushing guide roller and a second pushing guide roller being installed on the inner side of the pushing mechanism, and an annular cutter and a straight cutter being installed on the surface of the crushing component.

[0006] Furthermore, the processing table has a first end plate integrally formed on its side, the pushing mechanism is installed on the inner side of the first end plate, the top of the discharge box has a second end plate integrally formed, and the crushing component is fixed on the inner side of the second end plate.

[0007] Furthermore, the pushing mechanism includes a first motor, a transmission box, a first pushing guide roller, and a second pushing guide roller. The output end of the first motor is fixedly connected to the central rod of the second pushing guide roller, and the transmission box is screwed to the outside of the first end plate.

[0008] Furthermore, the first motor is screwed to the outside of the transmission box, and a gear set structure is installed inside the transmission box. The first motor drives the first push guide roller to rotate through the gear set inside the transmission box. Grooves are provided on the surfaces of both the first push guide roller and the second push guide roller.

[0009] Furthermore, a pin is inserted into the groove, and the pins on the first and second push guide rollers are staggered. A gap is provided between the first and second push guide rollers, and the end of the pin protrudes from the surface of the first and second push guide rollers.

[0010] Furthermore, the crushing assembly includes a second motor, a crushing guide roller, an annular cutter, and a straight cutter. The second motor is screwed onto the surface of the second end plate, and a drive shaft is inserted into the output end of the second motor. A central sleeve is integrally formed at the end of the crushing guide roller, and the inner wall of the central sleeve is keyed to the surface of the drive shaft.

[0011] Furthermore, the crushing guide roller has transmission arms welded to both ends, the straight cutter is screwed to the end of the transmission arm, the end of the crushing guide roller has a slot, and the surface of the crushing guide roller has a mating groove.

[0012] Furthermore, the inner side of the annular cutter is integrally formed with a docking block, which is used to be embedded into the interior of the docking groove. A locking pin is inserted into the interior of the groove, and the locking pin passes through the surface of each docking block in sequence. One end of each annular cutter is tapered.

[0013] The beneficial effects of this utility model are:

[0014] 1. The scrap wind turbine blade crushing device reduces the initial cutting requirements of wind turbine blades. Through horizontal conveying, larger wind turbine blade fragments can be placed directly, and then pre-processed by compression and pushing before being conveyed to the downstream crushing component. Therefore, larger wind turbine blades can be directly crushed, eliminating the need for excessive cutting of wind turbine blades in the early stage and simplifying the pre-processing process.

[0015] 2. After the wind turbine blades are placed on the processing table, the scrap wind turbine blade crushing device uses a pushing mechanism to crush the placed wind turbine blade fragments. During the crushing process, the wind turbine blades are pushed step by step through an interlocking method to ensure that even thicker wind turbine blades can still be pushed backward evenly, thereby improving the conveying efficiency and conveying stability.

[0016] 3. The shredding device for scrapped wind turbine blades is equipped with two cutting structures in the shredding assembly: a ring cutter and a straight cutter. After longitudinally cutting the wind turbine blades, it periodically provides transverse cutting, which makes the shredding degree more uniform and consistent. Furthermore, by controlling the number of ring cutters installed, the shredding size can be more precisely controlled. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides the following technical solution: a crushing device for scrapped wind turbine blades, comprising a crushing device body, the crushing device body including a processing table 1, a discharge box 2, a pushing mechanism 4, and a crushing mechanism. A crushing groove 9 is provided at one end of the processing table 1. The discharge box 2 is integrally formed at the bottom of the crushing groove 9. A crushing component 5 is detachably mounted on the top of the crushing groove 9. The pushing mechanism 4 is installed on the surface of the processing table 1. A first pushing guide roller 12 and a second pushing guide roller 13 are installed on the inner side of the pushing mechanism 4. An annular cutter 20 and a straight cutter 19 are installed on the surface of the crushing component 5. This crushing device is used to crush scrapped wind turbine blades.

[0026] In use, the wind turbine blade, which has been simply cut, is placed directly on the surface of the processing table 1 and pushed to dock with the pushing mechanism 4. The wind turbine blade then passes through the inside of the pushing mechanism 4 and is pushed toward the crushing component at the rear end. During this process, the wind turbine blade is also squeezed. Finally, after the squeezed wind turbine blade comes into contact with the crushing component 5, the wind turbine blade is crushed. The crushed material is then directly passed down through the crushing trough 9 and dropped into the discharge box 2 at the bottom for collection.

[0027] In this embodiment, the processing table 1 has a first end plate 3 integrally formed on its side, the pushing mechanism 4 is installed inside the first end plate 3, the top of the discharge box 2 has a second end plate 8 integrally formed, and the crushing component 5 is fixed inside the second end plate 8. This reduces the initial cutting requirements for wind turbine blades. By using horizontal conveying, larger wind turbine blade fragments can be placed directly, and then pre-processed by compression before being conveyed to the rear crushing component 5. Therefore, larger wind turbine blades can be directly crushed, eliminating the need for excessive pre-cutting and simplifying the pre-processing steps.

[0028] Specifically, the large wind turbine blades, after being slightly cut, are placed directly on the processing table 1, and one end of the wind turbine blade is placed against the area of ​​the pushing mechanism 4. The pushing mechanism 4 can then be used to push the wind turbine blade, eliminating the need to lift and transport a large number of small wind turbine blades after cutting.

[0029] In this embodiment, the pushing mechanism 4 includes a first motor 6, a transmission box 7, a first pushing guide roller 12, and a second pushing guide roller 13. The output end of the first motor 6 is fixedly connected to the central rod of the second pushing guide roller 13. The transmission box 7 is screwed onto the outside of the first end plate 3. The first motor 6 is screwed onto the outside of the transmission box 7. A gear set structure is installed inside the transmission box 7, and the first motor 6 drives the first pushing guide roller 12 to rotate through the gear set inside the transmission box 7. Grooves 14 are provided on the surfaces of both the first pushing guide roller 12 and the second pushing guide roller 13. A pin 15 is inserted into the groove 14, and the pins 15 on the first pushing guide roller 12 and the second pushing guide roller 13 are staggered. A gap is provided between the first pushing guide roller 12 and the second pushing guide roller 13, and the ends of the pins 15 protrude from the surfaces of the first pushing guide roller 12 and the second pushing guide roller 13. After the wind turbine blades are placed on the processing table 1, the pushing mechanism 4 compresses the placed wind turbine blade fragments. During the compression process, the wind turbine blades are gradually pushed through the insertion method to ensure that the thicker wind turbine blades can still be pushed backward evenly, thereby improving the conveying efficiency and conveying stability.

[0030] Specifically, after the wind turbine blade is moved to the inside of the pushing mechanism 4, the first pushing guide roller 12 and the second pushing guide roller 13 can be rotated by the first motor 6 and the transmission box 7. The middle of the first pushing guide roller 12 and the second pushing guide roller 13 are embedded into the top and bottom surfaces of the wind turbine blade by the protruding clips 15. As the first pushing guide roller 12 and the second pushing guide roller 13 continue to rotate, the inserted wind turbine blade can be pushed towards the rear end until it comes into contact with the crushing component 5.

[0031] In this embodiment, the crushing assembly 5 includes a second motor 10, a crushing guide roller 16, an annular cutter 20, and a straight cutter 19. The second motor 10 is screwed onto the surface of the second end plate 8, and a drive shaft 11 is inserted into the output end of the second motor 10. A central sleeve 17 is integrally formed at the end of the crushing guide roller 16, and the inner wall of the central sleeve 17 is keyed to the surface of the drive shaft 11. Transmission arms 18 are welded to both ends of the crushing guide roller 16, and the straight cutter 19 is screwed onto the end of the transmission arm 18. A slot 22 is provided at the end of the crushing guide roller 16, and a mating groove 23 is provided on the surface of the crushing guide roller 16. A mating block 25 is integrally formed on the inner side of the annular cutter 20. The mating block 25 is used to embed into the interior of the mating groove 23. A locking pin 21 is inserted into the interior of the slot 22, and the locking pin 21 passes through the surface of each mating block 25 in sequence. One end of each annular cutter 20 is tapered 24. It is equipped with two cutting structures: a ring cutter 20 and a straight cutter 19. After longitudinally cutting the wind turbine blade, it periodically provides transverse cutting, which can make the crushing degree more uniform and consistent. Furthermore, by controlling the number of ring cutters 20 installed, the crushing size can be more precisely controlled.

[0032] Specifically, after the crushing component 5 comes into contact with the wind turbine blade, it first performs multiple longitudinal cuts on the pushed wind turbine blade through the annular cutter 20. Then, as the crushing guide roller 16 rotates, the straight cutter 19 comes into contact with the longitudinally cut wind turbine blade, ultimately achieving a transverse cut. This forms the wind turbine blade into small fragments of uniform size, with each fragment having a shape close to a rectangular structure. The length of the crushed blade can be further controlled by controlling the transmission of the second motor 10 and the pushing speed of the pushing mechanism 4. In the crushing guide roller 16, each annular blade can be fixed by inserting with the locking pin 21. Therefore, the number of annular blades installed can also be controlled to control the width of the fragments generated when longitudinally cutting the wind turbine blade.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
