Description

Technical Field

[0001] This invention relates to the field of stone crushing equipment technology, specifically to a stone crushing device and method for shaping old cement concrete crushed material. Background Technology

[0002] With the acceleration of urbanization and the rapid development of highway construction, my country generates 40 million tons of construction waste annually, of which concrete blocks account for about 34%, or about 13.6 million tons of waste concrete. Traditional treatment methods, such as transporting them to the suburbs for open-air dumping or landfilling, not only cause environmental pollution but also occupy land and damage the ecological environment. In order to reduce the amount of construction waste and utilize it as a resource, crushing equipment is used to crush these waste cement concretes. To reduce the number of needle-shaped and flaky particles during the crushing process, impact crushers are usually selected. However, when current impact crushers are crushing, the high-speed rotating rotor and hammer continuously impact and crush the material, resulting in a short service life of key parts, requiring frequent replacement, and producing a lot of fine powder. The presence of fine powder during further crushing will affect the particle size distribution of the subsequent products, thereby increasing the production cost of recycled crushed stone. For example, the environmentally friendly impact crusher disclosed in announcement number CN116328893B, although it reduces the amount of dust emerging from the feed port through intermittent feeding and dust collection, still relies on the rotor and hammer to continuously impact the material during crushing. This results in a short service life of key parts and the need for frequent replacement. Although intermittent dust collection can reduce the impact on the crushing of the next batch of material, the particle size distribution of the current batch of material will still be affected. The impact crusher with diverse discharge particle size disclosed in announcement number CN116510834B also suffers from the problem of short service life of key parts and the problem of fine powder generated during crushing affecting the particle size distribution of the product. Therefore, a crushing device and method for shaping crushed stone material from old cement concrete are proposed. Summary of the Invention

[0013] Preferably, the movement distance of the crushing column is between 0 and 5 cm.

[0014] This invention provides a crushing device and method for shaping crushed stone from old cement concrete. Compared with the prior art, it has the following advantages: (1) The crushing device and method for shaping old cement concrete crushed material utilizes a visual recognition system to determine the shape of the material in advance. The matrix crushing column performs directional crushing on the weak parts of the material or areas prone to forming needle-like or flaky shapes according to the planned path, guiding the material to break in a more uniform direction, avoiding the generation of long strips or flat particles, significantly reducing the content of needle-like or flaky shapes in the finished product, improving the cubicity of the aggregate, accurately crushing and shaping, extending the service life of key components, reducing the amount of fine powder and the influence of fine powder on particle size distribution. At the same time, visual recognition + shaping planning can realize differentiated treatment of materials of different sizes. The matrix crushing column applies pressure or impact force as needed, making the crushing process more controllable, reducing the proportion of ultra-large or ultra-small particles, optimizing the final particle size distribution, making the output particle size more consistent, meeting the engineering gradation requirements, reducing the screening process, and facilitating the subsequent use of chemical impregnation and surface treatment to enhance the bonding force and interface strength between recycled aggregate and cement stone, mortar and other substrates. This allows the old cement concrete crushed material that has undergone shaping treatment to replace part or all of the natural aggregate to prepare recycled cement-stabilized crushed stone, thereby reducing production costs.

[0015] (2) The crushing device and method based on the shaping of old cement concrete crushed material can change the shape of the drill bit by extending the extension component, which can form stress concentration points in a specific direction on the material. Combined with the shaping scheme provided by the visual recognition system, the material can be guided to break along a preset path, avoiding needle-like particles caused by random crushing. It can not only penetrate the weak area of ​​the material more efficiently, but also automatically adjust the extension length and angle of the extension component according to the hardness of the material. It is especially suitable for brittle materials such as concrete. Different extension modes can deal with different types of materials (such as reinforced concrete, plain concrete, etc.) and the crushed particle shape can be customized according to different uses (such as sand making, roadbed aggregate, recycled concrete material).

[0016] (3) The crushing device and method based on the shaping of old cement concrete crushed material can significantly improve the overall mechanical properties of the output by screening out low-strength particles through the rolling component. After the high-strength particles are screened, the final product is closer to the standard of natural aggregates after chemical treatment such as chemical impregnation and surface treatment. It is suitable for concrete projects with higher requirements, promotes the upgrading of recycled aggregates from "subgrade cushion material" to "aggregate for structural concrete", improves the added value and market acceptance of recycled materials, and at the same time, the shaping component can dynamically adjust the shape of the crushing column, the impact path and other key parameters according to the strength non-compliance rate, and continuously optimize the crushing scheme.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0022] Please see Figures 1 to 10 The present invention provides the following technical solutions: Example 1: A crushing device for shaping old cement concrete crushed material includes a housing 1, a power motor 11 installed on one side of the housing 1 to provide power to the material to be shaped, and a shaping component for crushing and shaping old cement concrete material is provided inside the housing 1. The shaping component includes: a power push rod 2, a support rod 21, a mounting plate 22, a camera 23, a crushing column 24, a driving electromagnet 25, and a driven electromagnet 26. One end of the power push rod 2 is fixedly installed on the upper side wall of the housing 1. The power push rod 2 is used to provide power for the movement of the mounting plate 22. The side wall of the support rod 21 is fixedly installed on the output end of the power push rod 2. The other end of the support rod 21 is fixedly installed on the upper side of the mounting plate 22. The support rod 21 is used to provide support for the mounting plate 22. The mounting plate 22 is located inside the housing 1 to provide support for the shaping component. One end of the camera 23 is fixedly installed on the lower side of the mounting plate 22. The camera 23 is used to acquire images of the material to be crushed and shaped to provide a basis for determining the shaping scheme. The side wall of the crushing column 24 is slidably installed in the mounting plate 22 through protrusions to form a matrix crushing group. The crushing column 24 to be activated is determined according to the shaping scheme. One end of the driving electromagnet 25 is fixedly installed on the upper side of the mounting plate 22. One end of the driven electromagnet 26 is fixedly installed on the crushing column 24. After being energized, the driven electromagnet 26 and the driving electromagnet 25 are magnetically engaged, driving the crushing column 24 to slide back and forth in the mounting plate 22 to crush and shape the material. The shaping assembly also includes: an adjusting rod 12, a movable rod 13, a fixed rod 14, a baffle 15, and a support plate 16; One end of the adjusting rod 12 is fixedly installed on the side wall of the output shaft of the power motor 11. The adjusting rod 12 can slide and abut against the movable rod 13 under the drive of the power motor 11. One end of the movable rod 13 is hinged to the end of the fixed rod 14 with an opening through a torsion spring and a movable shaft. The movable rod 13 is used to transmit the power required to change the position of the baffle 15. One end of the fixed rod 14 is fixedly installed on the baffle 15. The side wall of the fixed rod 14 is provided with an opening. The fixed rod 14 can change the position of the baffle 15 under the action of external force. One end of the baffle 15 slides through the support plate 16. The baffle 15 is used to assist the unused crushing column 24 in fixing the position of the old cement concrete material to be crushed and shaped. The side wall of the support plate 16 is fixedly installed directly below the feed inlet inside the housing 1. The support plate 16 is used to place the old cement concrete material to be crushed and shaped.

[0023] In use, the control console rotates the motor 11 clockwise, causing the adjusting rod 12 to slide against the movable rod 13. Clockwise rotation of the movable rod 13 causes it to abut against the inner wall of one side of the fixed rod 14. When the movable rod 13 rotates counter-clockwise, it drives the fixed rod 14 to move synchronously. The fixed rod 14 then moves the baffle 15, causing it to slide upwards along the support plate 16 to its highest point. At this point, the crushed old cement concrete is fed into the machine through the inlet. The old cement or concrete material slides down the feeding channel onto the support plate 16 and is blocked by the baffle 15. Then, the power push rod 2 is controlled by the control console to move the support rod 21. The support rod 21 slides with the housing 1, so that the support rod 21 moves the mounting plate 22. The mounting plate 22 moves the camera 23 and the crushing column 24 installed on it, so that the crushing column 24 presses against the old cement concrete material to fix the old cement concrete block to be crushed and shaped. At the same time, the camera 23 takes a picture of the old cement concrete material to be shaped and transmits it to the vision detection system in the control console for image recognition. According to the shape and size of the material, the shaping plan is planned and the crushing column 24 that needs to be moved is determined. After the shaping scheme is planned, the corresponding driving electromagnet 25 and driven electromagnet 26 are energized by the control console, so that the driving electromagnet 25 and driven electromagnet 26 repel each other magnetically after being energized. Under the drive of the repulsive force, the driven electromagnet 26 drives the corresponding crushing column 24 to move, so that the crushing column 24 moves along the mounting plate 22 towards the side where the material is located, thereby crushing the material into several small pieces at a fixed point. The crushing process also has a shaping effect, making the crushed material more regular and reducing the probability of needle-shaped particles. This results in a better uniformity of particle size distribution in the crushed material. After crushing and shaping, the power motor 11 is rotated counterclockwise via the control console, causing the adjusting rod 12 and the movable rod 13 to separate. This prevents the movable rod 13 and the fixed rod 14 from providing upward force to the baffle 15, allowing the baffle 15 to return to its original position under its own weight. Figure 5 At the initial position shown, the material that has been crushed and shaped on the support plate 16 can slide down to below the support plate 16 for the next shaping process. Simultaneously, as the power motor 11 rotates counterclockwise, the control console also moves the power push rod 2 towards... Figure 1 Reset to the initial position shown, and simultaneously change the magnetism between the driving electromagnet 25 and the driven electromagnet 26, so that the breaking column 24 also moves in the same direction. Figure 8 The initial position shown is reset.

[0024] Furthermore, a return spring can be installed on the baffle 15 so that it can fall back to its original position more quickly when the upward thrust is lost.

[0025] Please see Figures 11 to 14 The present invention provides the following technical solutions: Example 2, the technical solution of which differs from Example 1 includes: an extension component for determining the crushing path according to the material characteristics is provided inside the housing 1. The extension component includes: a mounting column 27, a movable seat 28, an auxiliary blade 29, a guide rod 210, a fixing plate 211, a sliding push block 212, a spring 213, an adjusting slider 214, an adjusting electromagnet 215, and a power electromagnet 216. Both ends of the mounting column 27 are fixedly installed inside the crushing column 24. The mounting column 27 is used to provide support for some parts in the extension assembly. The bottom of the movable seat 28 is fixedly installed on the bottom of the inner wall of the crushing column 24. The auxiliary blade 29 is movably hinged in the movable seat 28 through the mounting shaft and the worm spring. The auxiliary blade 29 can extend out of the crushing column 24 under the action of external force. One end of the guide rod 210 is fixedly installed on the top of the inner wall of the mounting column 27. The fixing plate 211 is slidably sleeved on the outside of the guide rod 210. The fixing plate 211 can slide along the guide rod 210 under the drive of external force. The sliding push block 212 is slidably inserted into the fixing plate 211. The sliding push block 212 can slide along the fixing plate 211 under the action of external force. One end of the spring 213 is fixedly installed on the side wall of the sliding push block 212, and the other end of the spring 213 is fixedly installed on the side wall of the sliding push block 212. Fixed within the fixed plate 211, the spring 213 provides elastic force for the sliding push block 212 to reset. The side wall of the adjusting slider 214 is fixedly installed on the sliding push block 212, and the bottom of the adjusting slider 214 is provided with an inclined surface. The side wall of the pressing block is fixedly installed on the inner side wall of the mounting column 27, and the top of the pressing block is provided with an inclined surface that matches the bottom inclined surface of the adjusting slider 214. When the adjusting slider 214 moves downward, it slides with the inclined surface at the top of the pressing block, thereby driving the sliding push block 212 to slide along the fixed plate 211. The bottom of the adjusting electromagnet 215 is fixedly installed on the top of the fixed plate 211, and the top of the power electromagnet 216 is fixedly installed inside the mounting column 27. After being energized, the power electromagnet 216 and the adjusting electromagnet 215 are magnetically engaged, driving the fixed plate 211 to slide.

[0026] During use, in the process of fixed-point crushing and shaping according to the shaping scheme, in order to further ensure that the crushing path of the material follows the preset scheme during the crushing process, an extension component is set inside the crushing column 24. According to the crushing and shaping requirements, the control console controls the adjustment electromagnet 215 and the power electromagnet 216 to be energized, so that the adjustment electromagnet 215 and the power electromagnet 216 magnetically repel each other after being energized. Under the action of the repulsive force, the adjustment electromagnet 215 drives the fixed plate 211 to move downward. Through the sliding cooperation between the fixed plate 211 and the guide rod 210, the fixed plate 211 can only move in a straight line along the guide rod 210 when it moves. The fixed plate 211 drives the sliding push block 212 to move. 2. The adjusting slider 214 moves down synchronously. During the downward movement, the adjusting slider 214 slides against the extrusion block. Under the extrusion of the extrusion block, the adjusting slider 214 can slide from the side where the guide rod 210 is located to the side where the auxiliary knife 29 is located. This causes the adjusting slider 214 to drive the sliding push block 212 to push the auxiliary knife 29 to rotate around the mounting shaft. The auxiliary knife 29 extends out from the side of the crushing column 24 and unfolds. At this time, the control console controls the driving electromagnet 25 and the driven electromagnet 26 to be energized. The magnetism switches back and forth between mutual repulsion and attraction. This causes the crushing column 24 with the unfolded auxiliary knife 29 to hit the material multiple times and break it. By utilizing the mutual assistance between the auxiliary knives 29 of the adjacent crushing columns 24, the crushing path of the auxiliary material is almost the same as the preset plan. After the fixed-point crushing and shaping is completed, the control console controls the magnetic transformation between electromagnet 215 and power electromagnet 216 to achieve mutual attraction, thereby resetting the expansion assembly to its original position. Figure 11 The initial position is shown, and the shaping component is also reset to the initial position to await the crushing and shaping operation of the next material; In another embodiment, which differs from the aforementioned embodiment, the movable seat 28 is configured to be rotatably connected to the crushing column 24 and is equipped with a driving element, which enables the driving element to drive the movable seat 28 to deflect at a small angle around the guide rod 210 as the axis, thereby adapting to the crushing and shaping operation of irregular old cement concrete. Furthermore, the movable seat 28 can be changed to a three-layer structure, with the middle layer rotatably connected to the crushing column 24, the top layer connected to the left auxiliary blade 29 via a mounting shaft and a worm spring, and the bottom layer connected to the right auxiliary blade 29 via a mounting shaft and a worm spring. Each layer is equipped with a driving element, allowing the auxiliary blades on both sides to change their angles independently, making it more suitable for crushing and shaping irregular old cement concrete.

[0027] Please see Figures 15 to 16 The present invention provides the following technical solutions: The technical solution that differs from the previous embodiments includes: a crushing assembly for detecting the strength of crushed particles is provided inside the housing 1. The crushing assembly includes: a template 17, a power disc 3, a sliding rod 31, a connecting rod 32, a pressure plate 33, a limiting rod 34, a limiting plate 35, a steel wire 36, a stranded disc 37, and a drive motor 38. The inner ring of the power disc 3 is fixedly sleeved on the output shaft. An adjusting groove is provided on the side wall of the power disc 3. One end of the sliding rod 31 slides through the adjusting groove, and both ends of the sliding rod 31 slide against the inner wall of the housing 1. One end of the connecting rod 32 slides through the sliding rod 31. The top of the pressure plate 33 is fixedly installed at the bottom of the connecting rod 32. The pressure plate 33 can move with the rotation of the power disc 3 to crush and shape the material. One end of the limiting plate 35 slides through the pressure plate 33, and both ends of the limiting rod 34 are fixedly installed inside the housing 1. One end of the wire 4 slides out from the limiting plate 35. One end of the wire 36 is fixedly installed on the side wall of the limiting plate 35, and the other end of the wire 36 is fixedly installed on the stranding disc 37. The side wall of the stranding disc 37 is fixedly installed on the output end of the drive motor 38 through the drive shaft. The drive motor 38 is fixedly installed on the side wall of the housing 1 through the motor base. The drive motor 38 is used to provide power for the movement of the pressure plate 33. The side wall of the template 17 is fixedly installed inside the housing 1 and located directly below the pressure plate 33. The template 17 and the pressure plate 33 cooperate to detect the strength of the material after crushing and shaping.

[0028] When in use, after the crushed material has been processed by fixed-point crushing and shaping, it rolls down along the support plate 16 onto the template 17 below after the baffle 15 moves down. At this time, the control console starts the power motor 11 and the drive motors 38 on both sides. The power motor 11 drives the output shaft to rotate counterclockwise, and the output shaft drives the adjusting rod 12 to rotate counterclockwise. When the adjusting rod 12 rotates to the position of the movable rod 13, it will squeeze the movable rod 13 from... Figure 6 Rotate downwards as shown, causing one end of the movable rod 13 to move out from the opening side of the fixed rod 14, and then return to its original position under the action of the torsion spring after separation. Figure 5 The initial position shown allows the output shaft to rotate more than 360°. Simultaneously, the output shaft drives the power disc 3 to rotate. Adjustment grooves are formed on the surface of the power disc 3, with varying depths and height differences. The adjustment grooves slide against the sliding rod 31. When the power disc 3 rotates, the sliding rod 31 slides along the adjustment groove, driving the connecting rod 32 to move. The connecting rod 32 slides against the sliding rod 31, allowing the connecting rod 32 to move under external force. Figure 15 Moving from the lower left to the upper right, the connecting rod 32 can also drive the pressure plate 33 to... Figure 15The position shown moves back and forth from the side where the power motor 11 is located to the side where the adjusting rod 12 is located, so that the pressure plate 33 can also move back and forth in this direction. The pressure plate 33 crushes the broken material on the template 17, removes unqualified particles from the crushed material, and improves the strength of the final obtained particles. When the drive motor 38 on one side of the housing 1 starts and rotates clockwise, the drive motor 38 on the other side rotates counterclockwise. After the drive motor 38 starts, it drives the stranding disc 37, so that the stranding disc 37 on one side winds up the steel wire 36 and the stranding disc 37 on the other side releases the steel wire 36. The steel wire 36 drives the limiting plate 35 to move. The limiting rod 34 limits and guides the limiting plate 35. The limiting plate 35 and the pressure plate 33 slide together, so that the limiting plate 35 can drive the pressure plate 33 and the connecting rod 32 to move along the direction of the limiting rod 34. After moving to one end of the limiting rod 34, the rotation direction of the drive motor 38 is switched, so that the pressure plate 33 can move back and forth along the limiting rod 34 and also move in another direction to crush the crushed material on the template 17. Particles with qualified strength fall through the discharge hole of the template 17 and fall below under crushing, while particles with unqualified strength are crushed and discharged. In another embodiment, which differs from the aforementioned embodiment, air outlets are provided at both ends of the pressure plate 33, and a fan is connected to it through an air pipe to blow air into the casing 1, so that the crushed particles can be smoothly discharged from the discharge hole under the blowing force of the air.
