[0028] By adopting the above technical solution, the present invention has the following advantages:

[0029] 1. The crushing structure of the crushing mechanism can make the whole structure reciprocate toward the counter-attack structure with the help of the driving mechanism. When the construction waste enters the crushing mechanism along the upper end of the counter-attack structure with the help of the feeding mechanism, the waste will be impacted by the crushing structure and hit the counter-attack structure to cause a secondary impact. The impact force of the collision can break the construction waste into smaller structures. At the same time, the caliber of the crushing mechanism gradually decreases in the direction toward the discharge port, so that the waste is impacted more frequently in the direction close to the discharge port. In this process, the waste will gradually be broken into smaller states and enter the processing device from the discharge port. The crushing structure is arranged obliquely upward relative to the counter-attack structure, so that the waste can be thrown upward after being hit, which can prevent the waste from leaving the discharge port directly without being crushed, and can effectively ensure the crushing efficiency and quality. In order to ensure the crushing effect, the crushing structure is arrayed with attack teeth, and the upper end of the tooth body of the attack tooth is arranged obliquely downward to prevent the waste from accumulating on the tooth body. At the same time, the tooth body can face the waste directly, strengthen the strength of the tooth body structure, effectively ensure the crushing effect of the construction waste, and improve the waste treatment efficiency.

[0030] 2. The waste can be crushed into a small volume by attacking and counterattacking, but there are metal materials such as steel bars in the waste. In order to crush the waste as much as possible and separate materials such as concrete and stone from metal materials, an extrusion mechanism is provided below the discharge port. After the waste enters the processing device, it will pass through the extrusion teeth staggered between the extrusion roller and the roller body. The relatively arranged multiple extrusion teeth further squeeze and crush the waste by rotating, which can further reduce the size of the waste and separate more waste from metal materials, which can facilitate the subsequent screening of different wastes, improve the recycling efficiency and quality of the waste, and realize the rapid and stable processing of construction waste.

[0031] 3. After the mixed waste passes through the extrusion mechanism, it will contact the screening roller. The screening roller is provided with multiple strong magnetic structures. After the mixed waste contacts the screening roller, the metal part will be attracted by the strong magnetic structure and rotate with the screening roller. Other materials will fall into the screening mechanism for screening and recovery. When the screening roller passes the screening mechanism, it will contact the separation structure of the separation mechanism. The separation structure can separate metal waste such as steel bars from the strong magnetic structure. The metal waste will not be attracted and separated from the screening roller and fall to the separation mechanism. The separation mechanism can guide the metal waste so that the metal waste can smoothly enter a chamber of the recycling structure. The recycling structure is also evenly provided with multiple chambers relative to the screening mechanism. Different waste and waste of different specifications will enter different chambers. When the processing is completed, the user can open the chamber to quickly recycle the waste. Through the above structure, the processing device can realize fast and stable processing of construction waste, effectively reduce the cost of waste processing, and effectively improve the user experience.

[0041] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] Reference Figures 1 to 6 To achieve the above-mentioned purpose, the present invention proposes a processing device for mixed construction waste, comprising a crushing mechanism 1, an extrusion mechanism 2, and a screening mechanism 4. The crushing mechanism 1 comprises a crushing structure 11 and an impact structure 12. The bottom end of the crushing structure 11 and the bottom end of the impact structure 12 are clamped together to form a discharge port. The distance between the crushing structure 11 and the impact structure 12 gradually increases in a direction away from the discharge port. The crushing structure 11 is driven and connected to a driving mechanism, and the top of the impact structure 12 is connected to a feeding mechanism 13.

[0044] The extrusion mechanism 2 is connected to the crushing mechanism 1 and is located below the discharge port. The extrusion mechanism 2 includes at least two extrusion rollers 21 arranged in parallel. The two extrusion rollers 21 are provided with extrusion teeth that are staggered relative to each other.

[0045] The screening mechanism 4 includes a screening roller 41, a separation mechanism 5, and a screening mechanism 8. The screening roller 41 is located below the extrusion mechanism 2. A plurality of strong magnetic structures 43 are evenly spaced around the screening roller 41. The screening roller 41 is sequentially connected to the screening mechanism 8 and the separation mechanism 5 along the rotation direction. The separation mechanism 5 is provided with a separation structure 71 facing the screening roller 41. The separation structure 71 is connected to the outer periphery of the screening roller 41. The separation mechanism 5 and the screening mechanism 8 are connected with a recovery structure 9.

[0046] The crushing structure 11 of the crushing mechanism 1 can reciprocate toward the impact structure 12 with the help of the driving mechanism. When the construction waste enters the crushing mechanism 1 along the upper end of the impact structure 12 with the help of the feeding mechanism 13, the waste will be impacted by the crushing structure 11 and hit the impact structure 12 to cause a secondary impact. The impact force of the collision can break the construction waste into smaller structures. At the same time, the diameter of the crushing mechanism 1 gradually decreases in the direction toward the discharge port, so that the waste is impacted more frequently in the direction close to the discharge port. In this process, The waste will be gradually broken into smaller pieces and enter the processing device from the discharge port. The crushing structure 11 is arranged obliquely upward relative to the impact structure 12, so that the waste can be thrown upward after being hit, which can prevent the waste from leaving the discharge port directly without being broken, and can effectively ensure the crushing efficiency and quality. In order to ensure the crushing effect, the crushing structure 11 is arrayed with attack teeth, and the upper end of the tooth body of the attack tooth is arranged obliquely downward, which can prevent the waste from accumulating on the tooth body. At the same time, the tooth body can face the waste and strengthen the strength of the tooth body structure, which can effectively ensure the crushing effect of construction waste and improve the waste treatment efficiency.

[0047] The waste can be crushed into a small volume by attacking and counterattacking, but there are metal materials such as steel bars in the waste. In order to crush the waste as much as possible and separate concrete, stone and other materials from the metal materials, an extrusion mechanism 2 is provided below the discharge port. After the waste enters the processing device, it will pass through the extrusion teeth staggered between the extrusion roller 21 and the roller body. The relatively arranged multiple extrusion teeth further squeeze and crush the waste by rotating, which can further reduce the size of the waste and separate more waste from metal materials, which can facilitate the subsequent screening of different wastes, improve the recycling efficiency and quality of the waste, and realize fast and stable processing of construction waste.

[0048] After the mixed waste passes through the extrusion mechanism 2, it will contact the screening roller 41. The screening roller 41 is provided with a plurality of strong magnetic structures 43. After the mixed waste contacts the screening roller 41, the metal part will be attracted by the strong magnetic structure 43 and rotate with the screening roller 41. Other materials will fall into the screening mechanism 8 for screening and recovery. When the screening roller 41 rotates through the screening mechanism 8, it will contact the separation structure 71 of the separation mechanism 5. The separation structure 71 can separate metal waste such as steel bars from the strong magnetic structure 43. The metal waste will not be attracted and separated from the screening roller 41 and fall to the separation mechanism 5. The separation mechanism 5 can guide the metal waste so that the metal waste can smoothly enter a chamber of the recovery structure 9. The recovery structure 9 is also evenly provided with a plurality of chambers relative to the screening mechanism 8. Different waste and waste of different specifications will enter different chambers. When the processing is completed, the user can open the chamber to quickly recover the waste. Through the above structure, the processing device can realize fast and stable processing of construction waste, effectively reduce the cost of waste processing, and effectively improve the user experience.

[0049] Combined with reference Figures 2 to 4 The separation mechanism 5 includes a guide structure 6 and a separation component 7. The inner wall of the guide structure 6 is provided with an inner guide rail 64, and the outer periphery of the guide structure 6 is provided with an outer guide rail 65. One end of the separation component 7 is slidably connected to the inner guide rail 64, and the other end is drivingly connected to a driving chain 66. The driving chain 66 is slidably connected to the outer guide rail 65, and the driving chain 66 is drivingly connected to the driving structure.

[0050] The separation mechanism 5 itself includes a guide structure 6 and a separation component 7, and the separation component 7 can be composed of one or more separation structures 71. The guide structure 6 is provided with an inner guide rail 64 and an outer guide rail 65, so that the separation component 7 can be more stable when moving on the inner and outer guide rails. The inner guide rail 64 is used for balance, and the outer guide rail 65 is slidably connected with a drive chain 66, which is driven and connected to the separation component 7 by the drive chain 66. The separation component 7 can be made to reciprocate on the guide structure 6 according to the guide direction through the drive chain 66. The reciprocating motion of the drive component is used to scrape the screening roller 41, so that the metal materials such as steel bars adsorbed on the strong magnetic structure 43 can be efficiently hung down, and then the guide structure 6 guides the material itself to the recovery structure 9, so that the material itself is easy to recycle. The above structure can effectively improve the waste processing rate.

[0051] Combined with reference Figure 3 to Figure 4 The separation structure 71 includes a first power part 72 and a first sealing part 73. The driving chain 66 is located on one side of the first power part 72. One end of the first power part 72 is rotatably connected to the driving chain 66, and the other end is connected to one end of the first sealing part 73.

[0052] The first sealing portion 73 is arc-shaped. A balance wheel is provided at one end of the first sealing portion 73 away from the first power portion 72. The balance wheel is slidably connected to the inner guide rail 64. The first sealing portion 73 and the first power portion 72 are clamped together to form a scraping portion 74. The scraping portion 74 is connected to the outer periphery of the screening roller 41. The first sealing portion 73 is provided with a strong magnetic component 75.

[0053] The separation structure 71 is composed of a first power part 72 and a first sealing part 73. The first power part 72 is a straight plate, which can facilitate the transmission of the power provided by the drive chain 66 to the entire separation structure 71, so that the separation structure 71 can stably scrape the outer periphery of the screening roller 41, so that the separation structure 71 can efficiently separate the metal waste from the strong magnetic structure 43. The first sealing part 73 is an arc shape, which relies on the balance wheel to make the moving trajectory of the separation structure 71 more stable. The scraping part 74 is at the tip of the separation structure 71, and the metal waste can be separated from the screening roller 41 by scraping. In addition, a strong magnetic component 75 is provided on the first sealing part 73, which can further separate the metal waste from the screening roller 41 and be captured by the separation structure 71, so that the separation mechanism 5 can guide the waste to the recovery structure 9 for recycling, which can avoid the metal waste from splashing after separating from the screening roller 41, and can efficiently recycle the waste.

[0054] Combined with reference Figure 4 The guide structure 6 includes a working portion 61, a transfer portion 62, and a transition portion 63. The working portion 61 is arranged toward the screening roller 41, the transfer portion 62 is arranged away from the screening roller 41, and at least two transition portions 63 are provided, and the transition portion 63 is located between the working portion 61 and the transfer portion 62;

[0055] The inner guide rail 64 at the working part 61 is connected to the outer guide rail 65, the distance between the inner guide rail 64 and the outer guide rail 65 at the working part 61 is equal everywhere, the distance between the inner guide rail 64 and the outer guide rail 65 at the transfer part 62 is the same everywhere, and the distance between the inner guide rail 64 and the outer guide rail 65 at the transfer part 62 is much greater than the distance between the inner guide rail 64 and the outer guide rail 65 at the working part 61;

[0056] When the separation structure 71 is in the transfer portion 62 , the scraping portion 74 penetrates the guide structure 6 .

[0057] In a feasible embodiment, the guide structure 6 as a whole can be divided into a working part 61, a transfer part 62, and a transition part 63. The inner track and the outer track are arranged on the working part 61, the transfer part 62, and the transition part 63. The distance between the inner guide rail 64 and the outer guide rail 65 at the working part 61 is almost the same. Because of the structure of the separation structure 71, the scraping part 74 can be supported by the first power part 72 and the first sealing part 73, and stand on the outer periphery of the guide structure 6 to form an edge. When the separation structure 71 passes through the strong magnetic structure 43, the waste can be separated quickly and stably. When the separation structure 71 passes through the transition part 63 The distance between the inner guide rail 64 and the outer guide rail 65 at the transition portion 63 gradually increases as the inner rail gradually bends toward the inside of the guide structure 6, so that the first sealing portion 73 will drive the scraping portion 74 to gradually rotate toward the inside of the guide structure 6. The distance between the inner guide rail 64 and the outer guide rail 65 at the transfer portion 62 is the same everywhere. It is connected to the transition portion 63, and can stably transfer the separation structure 71 while folding the separation structure 71, so that the separation structure 71 can be recycled. After passing through the transfer portion 62, the separation structure 71 will pass through another transition portion 63 and re-enter the working portion 61 to execute the scraping instruction.

[0058] A transition portion 63 is arranged toward the recovery structure 9, and because the separation structure 71 will gradually be received into the guide structure 6 at the transition portion 63, a plurality of separation structures 71 or other similar structures are driven simultaneously on the guide structure 6, and the tail ends of the plurality of separation structures 71 are connected, and one side of the first power portion 72 of the previous separation structure 71 is connected to the first sealing portion 73 of the next separation structure 71, and the first sealing portion 73 is arc-shaped. Because the motion trajectory of the drive chain 66 is determined, the next separation structure 71 gradually turns to the inside of the guide structure 6 along with the inner guide rail 64, and the relative position of the previous first power portion 72 itself remains unchanged, so that the previous separation structure 71 can scrape the next first sealing portion 73 at the transition portion 63. When the metal waste is separated from the strong magnetic component 75 by scraping, the metal waste will detach from the separation structure 71 and be received by the recovery structure 9 below the transition portion 63, so that accurate, efficient and stable recycling can be achieved, and the cost of waste recycling can be effectively reduced.

[0059] Combined with reference Figures 3 to 6The separation assembly 7 includes a separation structure 71 and a sealing structure 76, and one end of the sealing structure 76 is connected to the first sealing portion 73;

[0060] The sealing structure 76 includes a second power part 77 and a second sealing part 78. The second power part 77 is rotatably connected to the driving chain 66. The second sealing part 78 is slidably connected to the inner track. The distance between the first power part 72 and the first sealing part 73 connected to the guide structure 6 is equal to the distance between the second power part 77 and the second sealing part 78 connected to the guide structure 6. The second sealing part 78 is arc-shaped, and the curvature of the second sealing part 78 is smaller than that of the first sealing part 73.

[0061] When the sealing structure 76 is in the working portion 61 , the second power portion 77 is connected to the first sealing portion 73 and is parallel to the transmission direction of the driving chain 66 .

[0062] The separation assembly 7 may also be composed of a sealing structure 76 in addition to the separation structure 71. A set of separation assemblies 7 may be composed of one or more separation structures 71 and one or more sealing structures 76 as required. The sealing structure 76 includes a second power part 77 and a second sealing part 78. Its structure is similar to that of the separation structure 71, but the curvature of the second sealing part 78 is smaller than that of the first sealing part 73. When the sealing structure 76 is in the working part 61, the second power part 77 is connected to the first sealing part 73 and is flush with the transmission direction of the drive chain 66. When the sealing structure 76 is in front of the separation structure 71, it can still be used to separate the separation structure 71. 1, and because the arc of the second sealing portion 78 is small, the connection between the second sealing portion 78 and the second power portion 77 is always inside the guide structure 6. When the screening roller 41 is provided with a buffer tooth 42 for buffering, the buffer tooth 42 has a conflict with the separation structure 71 during rotation. When a sealing structure 76 is provided in front of the separation structure 71, the buffer tooth 42 can pass through the area of ​​the sealing structure 76, and the separation structure 71 can also scrape the surface of the screening roller 41. Through this structure, the linkage of the internal mechanism of the processing device can be effectively improved, the high integration of each mechanism can be ensured, and the waste processing efficiency can be effectively improved.

[0063] Combined with reference Figure 1 to Figure 2 The guide structure 6 includes a first separation portion and a second separation portion, the first separation portion is arranged toward the strong magnetic structure 43, and the second separation portion is located on one side of the first separation portion;

[0064] The distance between the inner guide rail 64 and the outer guide rail 65 at the second separation portion is much greater than the distance between the inner guide rail 64 and the outer guide rail 65 at the first separation portion, and a transfer portion is provided between the first separation portion and the second separation portion.

[0065] In another feasible embodiment, the guide structure 6 may include a first separation part and a second separation part, the first separation part is equivalent to the above-mentioned working part 61, and the second separation part is equivalent to the above-mentioned transfer part 62. The difference is that the first separation part and the second separation part are both arranged on the end face facing the screening roller 41, and the first separation part is directly opposite to the strong magnetic structure 43, so that the passing separation structure 71 can separate the metal waste from the screening roller 41. When the separation structure 71 gradually enters, the waste will be scraped off by the previous separation component 7, and the previous separation component 7 will constitute a slide rail structure, which can quickly transfer the material to the recovery structure 9, so as to efficiently recycle the waste and reduce the recycling cost.

[0066] Combined with reference Figure 1 to Figure 2 , the separation component 7 includes at least two separation structures 71, and the two separation structures 71 are connected at the tail ends;

[0067] When the separation structure 71 is in the second separation portion, the first power unit 72 is parallel to the transmission direction of the drive chain 66 .

[0068] Because when the separation structure 71 is in the second separation part, its outer periphery is aligned with the transmission direction of the drive chain 66. In the present embodiment, the separation assembly 7 includes a plurality of separation structures 71, and the preceding separation structure 71 enters the second separation part first, which can quickly form a more marked slide rail structure, thereby preventing waste from sliding into the interior of the separation mechanism 5 and improving the separation efficiency.

[0069] When buffer teeth 42 need to be installed on the screening roller 41 to improve the adsorption efficiency of metal waste, a sealing structure 76 can be added to the front and rear ends of the separation component 7 in this embodiment. The sealing structure 76 is used to allow the buffer teeth 42 to pass through, which can ensure the linkage of the machine body and avoid errors.

[0070] Combined with reference Figures 1 to 3 A plurality of buffer teeth 42 are evenly spaced circumferentially arranged on the screening roller 41 , each buffer tooth 42 corresponds to a strong magnetic structure 43 , and the plurality of buffer teeth 42 and the plurality of strong magnetic structures 43 are alternately arranged.

[0071] In order to prevent the mixed waste from being directly knocked out after reaching the screening roller 41, causing the waste to splash everywhere, and at the same time to prevent the metal waste from leaving the screening roller 41 due to the impact before the strong magnetic structure 43 absorbs the metal waste, a plurality of buffer teeth 42 are provided on the screening roller 41, and adjacent buffer teeth 42 cooperate with the screening roller 41 to form a receiving groove. The strong magnetic structure 43 is arranged in the groove body, which can ensure the stability of waste recovery and effectively reduce the recycling cost.

[0072] Combined with reference Figure 1 to Figure 2A buffer portion 3 is provided between the screening mechanism 4 and the extrusion mechanism 2. The buffer portion 3 is located below the extrusion mechanism 2. One end of the buffer portion 3 is connected to the screening roller 41, and the other end is located at one side of the extrusion mechanism 2.

[0073] The buffer portion 3 is provided with a packaging portion 31 facing the screening roller 41. The packaging portion 31 is arc-shaped and surrounds the screening roller 41. The separation mechanism 5 is located on one side of the packaging portion 31.

[0074] A plurality of ash removal holes are arranged in an array on the buffer portion 3 , and a dust suction mechanism is provided on the buffer portion 3 relative to the ash removal holes.

[0075] The buffer part 3 completely covers the bottom of the extrusion mechanism 2. The buffer part 3 can be used to prevent the mixed waste from splashing around and guide them to the screening roller 41. The packaging part 31 is connected to the buffer teeth 42. The screening roller 41 can be sealed while having the buffer teeth 42 to prevent the waste from falling directly into the device. Because a large amount of dust will be generated when the waste falls, in order to prevent the dust from damaging the internal equipment, a plurality of ash removal holes are arranged on the buffer part 3. After the mixed waste hits the buffer part 3, the dust will be raised, and the dust suction mechanism will absorb the dust through the ash removal holes, which can effectively reduce pollution and protect the equipment itself.

[0076] Combined with reference Figure 1 to Figure 2 , a vibration mechanism is provided on the screening mechanism 8, the distance between the screening mechanism 8 and the recovery structure 9 gradually decreases along the screening direction, a plurality of screening holes are arrayed on the screening mechanism 8, and the aperture of the screening holes gradually increases along the screening direction;

[0077] One end of the recovery structure 9 is connected to one side of the screening mechanism 8, and the other end is wrapped around one side of the separation mechanism 5. The recovery structure 9 is provided with a plurality of classification bins relative to the separation mechanism 5 and the screening mechanism 8. A storage trolley is slidably connected inside the classification bin, and the storage trolley is provided with a handle.

[0078] The screening structure is a slope structure. By using the vibration mechanism, the waste falling on it will gradually move downward, and the aperture of the screening hole will also gradually increase. The vibration mechanism can prevent the waste from accumulating in one position and can allow the waste to enter the corresponding position through the appropriate aperture as much as possible.

[0079] The recycling structure 9 is divided into a plurality of compartments, which surround the separation mechanism 5 and various positions of the screening structure. A storage cart with a handle is provided in the compartment. Materials can be stored by the storage cart, and the transfer of materials can be facilitated, which can effectively reduce the recycling cost of materials, improve the recycling efficiency, and provide users with a better use experience.
