Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a pretreatment technology and a compression technology for construction waste garbage, and in particular to a construction waste extrusion device. Background Art

[0002] The extrusion treatment of construction waste is a means of resource recovery and reuse. It mainly applies a certain pressure to the construction waste to reduce its volume and increase its density, thereby facilitating transportation, storage and subsequent treatment. Therefore, many prior arts disclose extrusion treatment devices for construction waste, such as:

[0003] CN202420166574.5 discloses a garbage compression device (published on 2024-09-13); CN202322607735.8 discloses a construction waste compression device (published on 2024-04-19); these traditional extrusion devices usually compress waste materials through multi-angle or multi-directional compression mechanisms to form a solid block structure. This multi-angle or multi-directional compression method can ensure that the waste materials are subjected to uniform pressure in multiple directions, thereby reducing gaps or hollow points in the block structure.

[0004] However, simple linear compression has certain limitations when dealing with construction waste. First, linear compression mainly applies pressure to the waste in a fixed direction, which can easily lead to the waste not being able to fully fill all spaces during the compression process, thus forming gaps or hollow spots in the block structure.

[0005] Gaps or hollow spots can reduce the density and strength of the block structure, making it more vulnerable to damage during use. They can also become accumulation points for moisture and air, making the block structure more susceptible to moisture, mold or corrosion in a humid environment. They can also affect the stability and durability of the block structure, reducing its value for recycling.

[0006] To this end, the present invention proposes a construction waste squeezing device. Summary of the invention

[0007] In view of this, the embodiment of the present invention hopes to provide a construction waste extrusion device to solve or alleviate the technical problems existing in the prior art, that is, how to further eliminate the gaps or hollow points generated during the compression process, and at least provide a beneficial option for this; the technical solution of the present invention is implemented as follows:

[0008] The construction waste extrusion device is mainly composed of a box body 1, a first pressing mechanism 3 and a second pressing mechanism 4. The surface of the box body 1 is provided with a long strip containing groove 101 for containing construction waste. The first pressing mechanism 3 is arranged above the containing groove 101, and its design purpose is to initially squeeze the waste in a linear manner and press it into a solid flat shape. The second pressing mechanism 4 is located on one side of the containing groove 101, and has two functions: multi-angle circulation extrusion and linear extrusion.

[0009] During operation, the first pressing mechanism 3 is first started to perform preliminary linear extrusion on the construction waste. Then, the second pressing mechanism 4 performs multi-angle shaking extrusion on the waste after preliminary extrusion in a universal angle circular adjustment manner to further eliminate possible gaps and hollow points. Finally, the second pressing mechanism 4 performs final extrusion on one side of the waste again in a linear extrusion manner to ensure that the waste is compressed into a solid small block.

[0010] In one embodiment, the box body 1 is provided with a pressure sensor 2 for detecting the squeezing effect of the initial squeezing at the corresponding opening of the receiving groove 101. When the pressure sensor 2 detects that the first squeezing mechanism 3 squeezes the construction waste into a solid flat shape, an electrical signal is sent to the controller, and the controller further starts the operation of the second squeezing mechanism 4.

[0011] In one embodiment, the first pressing mechanism 3 mainly includes a first telescopic member 301 and a first pressing block 302. The first telescopic member 301, specifically a first hydraulic cylinder, is mounted on the stand 102, and the stand 102 is fixedly connected to the box body 1 to ensure the stability of the entire mechanism. The telescopic movement of the first telescopic member 301 can drive the first pressing block 302 to rise and fall into the receiving tank 101, thereby squeezing the waste.

[0012] In particular, a slide rail shaft 303 is provided on the outside of the first pressing block 302. This design enables the first pressing block 302 to slide along the stand 102 during the lifting process, thereby ensuring the accuracy of extrusion and improving the operating efficiency of the mechanism.

[0013] In one embodiment, the second pressing mechanism 4 is mainly composed of a second telescopic member 401, a second pressing block 402, a sleeve 403 and a universal adjustment assembly 404. The second telescopic member 401, which uses a second hydraulic cylinder as a driving source, is responsible for driving the sleeve 403 to perform telescopic movement. The end of the second pressing block 402 is designed with a spherical portion 4021. This design enables the second pressing block 402 to roll and fit in the sleeve 403 through the spherical portion 4021, thereby achieving flexible angle adjustment. A universal adjustment assembly 404 is installed inside the sleeve 403, which is responsible for adjusting the angle of the second pressing block 402 during the multi-angle cyclic extrusion process to ensure the uniformity and comprehensiveness of the extrusion.

[0014] In one embodiment, the universal adjustment assembly 404 is mainly composed of a disc-shaped first frame 4041, a disc-shaped second frame 4042 that is smaller than the diameter of the sleeve 403 and can move flexibly therein, and a plurality of third telescopic members 4043 arranged in an annular array between the first frame 4041 and the second frame 4042. The first frame 4041 is fixed in the sleeve 403, providing a stable support for the entire universal adjustment assembly. The second frame 4042 is connected to the first frame 4041 through a plurality of third telescopic members 4043, and can perform universal angle adjustment along a specified trajectory under the drive of the first frame 4041. In particular, the third telescopic member 4043 adopts a servo electric cylinder, and its cylinder body and piston rod are universally hinged on the opposite surface between the first frame 4041 and the second frame 4042 through a universal joint coupling 4044. This design enables the third telescopic member 4043 to accurately control the angle adjustment of the second frame 4042 when outputting different stroke amounts. The second pressing block 402 is fixed to the end surface of the second frame 4042 and performs angle adjustment and extrusion movement together with the second frame 4042 .

[0015] In one embodiment, two adjacent servo cylinders are cleverly arranged into a V-shaped structure. This arrangement not only optimizes space utilization, but also gives the component a unique compensation mechanism. Specifically, when one of the servo cylinders reaches its limit stroke point, the two adjacent servo cylinders can compensate for the stroke of the first servo cylinder by adjusting their own output strokes. This design ensures that the second frame 4042 can always maintain a stable motion trajectory and precise extrusion force during the entire angle adjustment and extrusion process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Enhanced compression effect: By introducing a universal adjustment component and multi-angle cyclic extrusion, the technology of the present invention can more completely fill the voids in the waste, significantly reduce or eliminate the formation of gaps and hollow points, thereby improving the compression density and strength of the waste.

[0018] 2. Optimized space utilization and stroke compensation: The V-shaped servo electric cylinder not only optimizes space utilization, but also ensures that the pressing block can maintain stable extrusion force and uniform pressure distribution throughout the extrusion process through the stroke compensation mechanism, further improving the compression effect.

[0019] 3. Improved work efficiency: Due to the improved compression effect and optimized extrusion process, the technology of the present invention can achieve the required compression density and strength more quickly, thereby improving work efficiency. In addition, the flexible stroke compensation mechanism also reduces the time wasted due to adjusting the extrusion direction or force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below;

[0028] Example: In the prior art, simple linear compression has certain limitations when processing construction waste. First, linear compression mainly applies pressure to the waste along a fixed direction, which easily leads to the waste not being able to fully fill all spaces during the compression process, thus forming gaps or hollow points in the block structure; for this reason, please refer to Figure 1-5 , this specific implementation will provide relevant technical solutions to solve the above technical problems:

[0029] The construction waste extrusion device comprises a box body 1 and a long strip containing groove 101 for containing wastes opened on its surface. The improvement of the present scheme is that it comprises a first pressing mechanism 3 arranged above the containing groove 101 for preliminarily extruding the wastes in a linear form;

[0030] It also includes a second pressing mechanism 4 disposed on one side of the containing tank 101 for performing multi-angle cyclic extrusion on the waste after the initial extrusion, and further performing linear extrusion on one side of the waste after the multi-angle cyclic extrusion is completed.

[0031] When in use, pour the construction waste into the receiving tank 101; the first pressing mechanism 3 first squeezes the construction waste into a solid flat shape (the first pressing mechanism 3 is not reset at this time), and then the second pressing mechanism 4 performs multi-angle cyclic shaking extrusion on one side of the solid flat waste in the form of universal angle cyclic adjustment to further eliminate possible gaps and hollow points; then the second pressing mechanism 4 performs linear extrusion on one side of the waste in the form of linear extrusion; finally, the waste will be compressed into a solid small block, the specific size of which is the maximum stroke point of the second pressing mechanism 4 and the first pressing mechanism 3, to the volume of the remaining surface of the receiving tank 101.

[0032] Specifically, the design principle of the present device is mainly based on two points: preliminary linear extrusion and multi-angle cyclic extrusion. The preliminary linear extrusion is achieved by the first pressing mechanism 3, and its function is to press the construction waste into a solid flat shape, providing a basis for subsequent multi-angle extrusion. The multi-angle cyclic extrusion is completed by the second pressing mechanism 4, which performs multi-angle shaking extrusion on the waste through universal angle cyclic adjustment to eliminate possible gaps and hollow points. This multi-angle extrusion method can cover all parts of the waste more comprehensively and ensure that the waste is fully compressed. Finally, the linear extrusion of the second pressing mechanism 4 is to give the waste a final shaping, ensuring that the waste is compressed into a solid small block that meets the requirements.

[0033] It can be understood that in the above scheme of the present embodiment: the present construction waste extrusion device effectively solves the problem of gaps and hollow points existing in the traditional extrusion device by combining preliminary linear extrusion and multi-angle cyclic extrusion. First, the preliminary linear extrusion can press the waste into a solid flat shape, providing a good foundation for the subsequent multi-angle extrusion. Secondly, the multi-angle cyclic extrusion can more comprehensively cover all parts of the waste through the universal angle circulation adjustment, eliminating possible gaps and hollow points. Finally, the shaping process of linear extrusion ensures that the waste is compressed into solid small blocks that meet the requirements, which is convenient for subsequent transportation and processing. This design not only improves the extrusion efficiency, but also improves the recycling rate of waste, with significant economic and environmental benefits.

[0034] In this solution, all electrical components of the device as a whole rely on AC power for energy supply; specifically, the electrical components of the device as a whole are conventionally electrically connected to the AC power output port through devices such as relays, transformers and button panels to meet the energy supply requirements of all electrical components of the device.

[0035] Specifically, a controller is also provided on the outside of the device, which is used to connect and control all electrical components of the device as a whole to be driven according to a pre-set program as a preset value and a driving mode; it should be pointed out that the above-mentioned driving mode corresponds to the corresponding start and stop time intervals, speed, power and other output parameters between the relevant electrical components mentioned below, that is, it meets the requirements of the relevant electrical components described below to drive the relevant mechanical devices to operate according to the functions described therein.

[0036] Furthermore, for the construction waste extrusion device disclosed in this specific embodiment, the (electrical components) as described in the context, and the (mechanism) composed thereof can all realize the corresponding operation start and stop time interval, speed, power and other output parameter controls through the controller executing a conventional PID controller algorithm (Proportion Integral Differential), that is, to realize the (mechanism) to execute a predetermined or preset action operation mode according to a certain function or motion trajectory.

[0037] In the technical solution provided in this embodiment, please refer to Figures 1 to 3 The box 1 is provided with a pressure sensor 2 for detecting the squeezing effect of the initial squeezing at the corresponding opening of the receiving groove 101. When the pressure sensor 2 detects that the first squeezing mechanism 3 squeezes the construction waste into a solid flat shape, an electrical signal is sent to the controller, and the controller further starts the operation of the second squeezing mechanism 4.

[0038] In the technical solution provided in this embodiment, please refer to Figure 1 , 2 4: The first pressing mechanism 3 includes a first telescopic member 301, and a first pressing block 302 driven by the first telescopic member 301 to rise and fall toward the containing groove 101; the first telescopic member 301 is on the stand 102, and the stand 102 is fixedly connected to the box body 1; a slide rail shaft 303 is provided on the outside of the first pressing block 302, and the slide rail shaft 303 is slidably matched with the stand 102. Among them, the first telescopic member 301 is a first hydraulic cylinder.

[0039] Specifically, it is based on hydraulic transmission and sliding fit. The first hydraulic cylinder serves as a power source, and provides lifting power for the first pressing block 302 through its telescopic movement. Hydraulic transmission has the characteristics of smooth transmission and high pressure, and is very suitable for construction waste extrusion devices that require large extrusion force. At the same time, the sliding fit between the slide rail shaft 303 and the stand 102 ensures the stability and accuracy of the first pressing block 302 during the lifting process. This design not only improves the extrusion effect, but also extends the service life of the mechanism.

[0040] It can be understood that in the above scheme of this embodiment: the telescopic movement of the first hydraulic cylinder can accurately control the lifting and lowering of the first pressing block 302, thereby realizing accurate extrusion of the waste. The sliding cooperation between the slide rail shaft 303 and the stand 102 further improves the stability and accuracy of the extrusion. This design enables the second pressing mechanism 4 to better adapt to wastes of different shapes and sizes, thereby improving the versatility and practicality of the device. At the same time, due to the high efficiency of the hydraulic transmission, this embodiment can also improve the working efficiency of the device and reduce energy consumption while ensuring the extrusion effect.

[0041] In the technical solution provided in this embodiment, please refer to Figure 5 : The second pressing mechanism 4 comprises a second telescopic member 401 for performing linear pressing, and a second pressing block 402 for pressing, and a spherical portion 4021 is formed at the end of the second pressing block 402;

[0042] The second telescopic member 401 drives a sleeve 403, and the second pressing block 402 is rollingly fitted in the sleeve 403 through the spherical portion 4021;

[0043] The sleeve 403 is provided with a universal adjustment component 404 for performing multi-angle cyclic adjustment. The universal adjustment component 404 is used to adjust the angle of the second pressing block 402 .

[0044] Wherein, the second telescopic member 401 is a second hydraulic cylinder.

[0045] Specifically, the design principle integrates hydraulic transmission, rolling fit and universal adjustment technology. The second hydraulic cylinder serves as a power source, and drives the sleeve 403 and the second pressing block 402 to perform linear extrusion through its telescopic movement. The spherical portion 4021 at the end of the second pressing block 402 and the rolling fit of the sleeve 403 realize flexible angle adjustment during the extrusion process. The universal adjustment component 404 further enhances the flexibility and accuracy of this angle adjustment, so that the second pressing block 402 can cyclically extrude the waste at multiple angles, effectively eliminating gaps and hollow points.

[0046] It can be understood that in the above scheme of this embodiment: the telescopic movement of the second hydraulic cylinder provides strong power support for extrusion, ensuring the depth and uniformity of extrusion. The rolling cooperation between the spherical part 4021 and the sleeve 403, and the introduction of the universal adjustment component 404, enable the second pressing block 402 to flexibly and comprehensively extrude the waste at multiple angles, effectively eliminating the gap and hollow point problems that are prone to occur in the traditional linear (straight line) extrusion method. This design not only improves the compression density and strength of the waste, but also makes the compressed block more uniform and stable, which is convenient for subsequent transportation and processing.

[0047] In the technical solution provided in this embodiment, please refer to Figure 5 The universal adjustment assembly 404 includes a disc-shaped first frame 4041 fixed in the sleeve 403, a disc-shaped second frame 4042 smaller than the diameter of the sleeve 403 so as to be able to move flexibly therein, and a plurality of third telescopic members 4043 arranged in a ring array between the first frame 4041 and the second frame 4042;

[0048] When different third telescopic members 4043 output different stroke amounts, the second frame 4042 can be controlled to perform universal angle adjustment along a specified trajectory;

[0049] The second pressing block 402 is fixedly mounted on the end surface of the second frame 4042 .

[0050] The third telescopic member 4043 is a servo electric cylinder, and the cylinder body and piston rod of the servo electric cylinder are universally hinged on the opposite surfaces between the first frame 4041 and the second frame 4042 through a universal joint coupling 4044 .

[0051] Specifically, based on the precise control of the servo electric cylinder and the flexible articulation of the universal joint coupling. The servo electric cylinder, as the third telescopic member 4043, has the characteristics of high control accuracy and fast response speed, and can accurately control the angle adjustment of the second frame 4042. The introduction of the universal joint coupling 4044 enables flexible universal articulation between the cylinder body and the piston rod, further enhancing the flexibility and accuracy of the angle adjustment. Under the coordinated action of multiple third telescopic members 4043, the second frame 4042 can perform universal angle adjustment along a specified trajectory, thereby driving the second pressing block 402 to cyclically extrude the waste at multiple angles.

[0052] It is understandable that in the above scheme of the present embodiment: the precise control of the servo electric cylinder makes the angle adjustment of the second frame 4042 more precise and stable, effectively avoiding the gap and hollow point problems caused by the inaccurate angle adjustment in the traditional extrusion method. The flexible articulation of the universal joint coupling further enhances the flexibility and adaptability of the angle adjustment, so that the second pressing block 402 can comprehensively and evenly extrude the waste at multiple angles. This design not only improves the compression density and strength of the waste, but also makes the compressed block more uniform and stable, which is convenient for subsequent transportation and processing.

[0053] In the technical solution provided in this embodiment, please refer to Figure 5 : Every two adjacent servo electric cylinders are in a V shape; and when one servo electric cylinder reaches a limit stroke point, the other two adjacent servo electric cylinders can compensate for it.

[0054] Specifically, it is mainly based on the precise control of the servo electric cylinder and the compensation mechanism of the V-shaped arrangement. The servo electric cylinder, as the third telescopic member 4043, has a high-precision stroke control capability, which can ensure the precise movement of the second frame 4042 during the extrusion process. The introduction of the V-shaped arrangement cleverly utilizes the spatial relationship between adjacent servo electric cylinders to form a mutual compensation mechanism. When one of the servo electric cylinders reaches the limit stroke, the two adjacent servo electric cylinders can compensate for the insufficient stroke of the first servo electric cylinder by increasing or decreasing their own stroke, thereby maintaining the stability and accuracy of the entire component.

[0055] It can be understood that in the above scheme of this embodiment: the compensation mechanism of the V-shaped arrangement enables the component to more flexibly and accurately adjust the angle and extrusion force of the second pressing block 402 when facing waste materials of complex shapes and sizes. This design not only improves the compression effect of the waste, but also reduces the risk of uneven extrusion or failure caused by the stroke limitation of the servo electric cylinder. At the same time, this implementation also enhances the reliability and durability of the device and extends the service life of the equipment. In addition, this design also simplifies the maintenance and debugging process of the equipment and reduces the cost of use.

[0056] In summary, in view of the related problems in the traditional technology, this specific embodiment is based on the construction waste extrusion device provided above, and adopts the following technical means or features to achieve the solution:

[0057] (1) Multi-angle cyclic extrusion: The technical solution of the present invention introduces a universal adjustment component 404, which realizes multi-angle adjustment of the second pressing block 402 through multiple servo electric cylinders (third telescopic member 4043) and a universal joint coupling 4044. This design enables the pressing block to no longer only apply pressure in a single direction, but to be able to perform cyclic extrusion at multiple angles. The principle of multi-angle cyclic extrusion is that by constantly changing the extrusion direction, the gaps in the waste can be filled more effectively, reducing or eliminating the formation of gaps and hollow points. This is because the waste particles will be rearranged and tightly stacked under extrusion in different directions, thereby increasing the compression density.

[0058] (2) Flexible stroke compensation: Each pair of adjacent servo cylinders is arranged in a V shape and has stroke compensation capability. This means that when a servo cylinder reaches its limit stroke, the adjacent cylinder can adjust its stroke to compensate for this shortfall. The principle of this stroke compensation mechanism is that it ensures that the pressing block can maintain a stable extrusion force and uniform pressure distribution throughout the extrusion process regardless of how the shape and size of the waste material changes. This avoids the situation of local under- or over-extrusion caused by the stroke limitation of a single cylinder, thereby further improving the compression effect.

[0059] (3) Combination of hydraulic and electric: The technical solution of the present invention uses a second hydraulic cylinder (second telescopic member 401) as the main driving force source, and is combined with a servo electric cylinder for fine adjustment. Hydraulic transmission has the characteristics of smooth transmission and high pressure, and is suitable for construction waste extrusion devices that require greater extrusion force; while the servo electric cylinder provides high-precision stroke control and flexible angle adjustment capabilities. The principle of this combination is that it makes full use of the respective advantages of hydraulic and electric transmission, which not only ensures the strength and stability of extrusion, but also realizes flexibility and accuracy in the extrusion process. This comprehensive transmission method enables the device to better adapt to waste materials of different shapes and sizes, and improves compression efficiency and compression quality.

[0060] The above-mentioned embodiments only express the implementation methods of the relevant practical applications of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
