[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0034] Reference Figure 1-6 As shown, a combination tool for cleaning a box includes a tool holder 10, a first tool body 20, and a second tool body 30.

[0035] The tool holder 10 has one side for fixing the first tool body 20 and the second tool body 30, and the other side for connecting to an external fixing device.

[0036] The first cutter body 20 is used to crush and cut materials in the non-central area of ​​the casing. The second cutter body 30 is rotatably connected to the cutter holder 10 and is used to crush and cut materials in the central area of ​​the casing. The second cutter body 30 also includes a hollow shaft 31. One end of the hollow shaft 31 is connected to the first outlet, and the other end of the hollow shaft 31 is used to install a rotary joint and connect to a storage container to collect crushed materials.

[0037] Reference Figure 1-2As shown, the first cutter body 20 is disposed along the edge of the cutter holder 10 and is fixedly connected to the cutter holder 10. The first cutter body 20 and the cutter holder 10 form a cutting cavity 40. One end of the second cutter body 30 is rotatably connected to the cutter holder 10, and the other end extends within the cutting cavity 40. The first blade 20 has a tooth 211 at one end away from the blade holder 10. The tooth 211 is used to cut thicker material on the side wall of the box. In some embodiments, the tooth 211 is evenly distributed on the first blade 20. Specifically, the tooth 211 is evenly spaced and has a spike 2111 at one end away from the blade holder 10. The spike 2111 can cut thicker material on the side wall of the box better and improve cleaning efficiency. The tip of the spike 2111 can be a right triangle or an acute triangle, both of which can effectively cut thicker material on the side wall of the box. The tooth 211 is fixedly connected to the first blade 20, such as by welding or bonding, preferably by welding. Alternatively, a mold can be pre-set so that the tooth 211 and the first blade 20 are integrally formed.

[0038] In some embodiments, the first blade body 20 includes four spaced-apart root-cleaning blades 21 with identical structures. Specifically, the blade holder 10 is a square structure, and the four root-cleaning blades 21 are respectively fixedly disposed at the four corners of the blade holder 10. One end of each root-cleaning blade 21 connected to the blade holder 10 is a triangular prism, and the cross-section of the triangular prism is an isosceles right triangle. The right-angled side of the isosceles right triangle coincides with two sides of one corner of the square blade holder 10, and the hypotenuse of the isosceles right triangle is connected to two sides of one corner of the square blade holder 10. This structure increases the strength of the root-cleaning blade 21 and improves its durability. More specifically, in the root-cleaning blade 21, the two faces containing the right-angled side are integrally formed, and the face containing the hypotenuse is welded together with the two faces containing the right-angled side. (Refer to...) Figure 1-3 As shown, in some embodiments, the end of the root-cleaning blade 21 away from the blade holder 10 has an inclined prism surface 22 on its inner side, which faces the cutting part 32. In use, the root-cleaning blade 21 is inserted into the material. As the blade continues to move relative to the material, the material moves towards the cutting part 32 of the second blade body 30 under the pressure of the inclined prism surface 22. This portion of the material is ultimately cut and crushed by the cutting part 32 and then discharged from the casing through the first extraction port 34. Furthermore, during the process of the cutting part 32 crushing the material, the material is rapidly impacted by the centrifugal force generated when the cutting part 32 rotates. Some material is directly crushed, while some rebounds through the inclined surface and continues to enter the working area of ​​the cutting part 32, thereby achieving cyclic cutting and crushing, greatly improving the crushing and cleaning efficiency.

[0039] Reference Figure 4 As shown, the second blade body 30 is provided with a cutting part 32, a material wrapping part 33 and a first material extraction port 34.

[0040] The cutting section 32 includes multiple cutting blades 321 and a central blade 322. These multiple cutting blades 321 are spaced and inclinedly arranged on the outer wall of the hollow shaft 31. When the cutting section 32 rotates and cuts, it remains within the cutting cavity 40. The central blade 322 is located within the hollow shaft 31. In some embodiments, there are three cutting blades 321, or more can be provided as needed. The cutting blades 321 are equally spaced on the hollow shaft 31, and each cutting blade 321 has a cutting edge that protrudes from the cutting cavity 40. That is, there is a height difference between the first blade body 20 and the cutting blades 321. When cleaning the casing using the cutting blades 321, the cutting edge of the cutting blade 321 contacts the material faster than the first blade body 20, allowing the material in the center of the casing to be cleaned first. This facilitates the first blade body 20 in cutting thicker material on the side walls of the casing. In some embodiments, the central blade 322 is fixedly disposed at the first extraction port 34 and protrudes from the cutting cavity 40. Similarly, the central blade 322 can quickly cut and crush the material in the center of the casing. In conjunction with the cutting blade 321, it can quickly clean the material in the central area of ​​the casing, further improving cleaning efficiency. Specifically, the central blade 322 can be S-shaped, straight, or other shapes, preferably S-shaped, wherein the two ends of the S are respectively fixedly disposed on the inner wall surface of the first extraction port 34.

[0041] Reference Figure 4 As shown, the wrapping section 33 includes an arc-shaped wrapping plate 331 and an annular flange 332 disposed on the arc-shaped wrapping plate 331. When the wrapping plate 331 rotates, the annular flange 332 prevents some material from dispersing, concentrates the dispersed material, and brings it into the area where the first extraction port 34 is located. The crushed material is then quickly discharged through the first extraction port 34. In some embodiments, there are three cutting blades 321, dividing the plane where the cutting blades 321 are located into three areas. Two wrapping plates 331 are equally spaced and disposed in two of the areas, and the remaining area is used to house the side tube. In use, the cutting blades 321 crush and cut the material in the casing, and the wrapping plate 331 concentrates a portion of the dispersed material outside the first extraction port 34 and brings it into the area where the first extraction port 34 is located. The remaining material is processed through the second extraction port 351 on the side tube 35.

[0042] Reference Figure 1-4 As shown, the first extraction port 34 is located on the second blade body 30 and communicates with the hollow shaft 31. A side tube 35 is arranged laterally and communicates with the hollow shaft 31. The side tube 35 has a second extraction port 351. The first extraction port 34 is used to extract crushed material located in the middle of the casing, and the second extraction port 351 is used to clean material in non-central areas. The second blade body 30 is rotatably connected to the blade holder 10. A fixed seat is provided at the end of the second blade body 30 away from the cutting part 32 for connecting with the drive device and installing a rotary joint so that when the second blade body 30 rotates, the material extracted by the first extraction port 34 and the second extraction port 351 enters the predetermined container through the hollow shaft 31. According to Bernoulli's principle, when the diameter of the first extraction port 34 is larger than the diameter of the second extraction port 351, the suction force of the second extraction port 351 can be significantly enhanced, thus ensuring that both the first extraction port 34 and the second extraction port 351 have the suction force to extract material. In some embodiments, a third extraction port 352 is provided on the side tube 35 near the second extraction port 351. The third extraction port 352 faces the same direction as the first extraction port 34, and the diameter of the second extraction port 351 is larger than the diameter of the third extraction port 352. The third extraction port 352 is used to clean materials located at the edges. The second extraction port 351 is horizontal, while the first extraction port 34 and the third extraction port 352 are vertical. Therefore, the material that the second extraction port 351 can extract is limited, and some material at the bottom cannot be extracted through the first extraction port 34 and the second extraction port 351. By providing the third extraction port 352, this part of the material can be extracted and cleaned, further improving the cleaning efficiency.

[0043] In some embodiments, the cross-section of the box to be cleaned is square, and the combined cutter has a corresponding square structure. The combined cutter is fixed and will not move. The box to be cleaned is fitted onto the cutter of the present invention, and the box and the combined cutter are moved relative to each other by external force. In use, firstly, the power system of the equipment is turned on, the second cutter body 30 rotates at high speed, and the first material extraction port 34 generates suction; secondly, the box and the cutter body are pushed to move relative to each other, and the cutter body comes into contact with the material in the box; thirdly, the cutting blade 321 and the center blade 322 first contact the center material and crush and cut the contacted material, and then discharge it in time through the first material extraction port 34. Then, the first cutter body 20 includes four root cleaning blades 21 located on the cutter holder 10. The root cleaning blades 21 will cut the thicker material on the side wall of the box, especially The material accumulation is particularly thick at the four corners inside the casing. The oblique prism surface 22 within the cleaning blade 21 compresses this material towards the cutting blade 321. The high-speed rotating cutting blade 321, in conjunction with the material wrapping part 33, quickly cleans this material. Some material collides with the oblique prism surface 22 due to the high-speed rotation of the cutting blade 321 or the material wrapping part 33. Some broken material is extracted by the second and third extraction ports 351 and 352, while the remaining material rebounds through the oblique prism surface 22 and re-enters the cutting range of the cutting blade 321. Fourthly, after cleaning, the cleaned casing is removed, and a new casing to be cleaned is inserted.

[0044] This invention discloses a combined cutting tool for cleaning a casing. The first cutting tool 20 and the second cutting tool 30 work together to crush and cut materials. The first extraction port 34, the second extraction port 351, and the third extraction port 352, in conjunction with the material wrapping part 33, extract the crushed material. This not only provides high cleaning efficiency but also removes all material adhering to the casing. Besides the aforementioned square casing, the cross-sectional shape of the combined cutting tool can be modified to suit different casing shapes, while still achieving excellent cleaning results. Furthermore, this invention has a simple structure, is easy to operate, and is suitable for widespread adoption.

[0045] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
