Description

Technical Field

[0001] The present invention relates to the technical field of concrete recycling, and specifically to a concrete recycling device for construction. Background Art

[0002] Ready-mixed concrete is widely used in many fields such as civil engineering, such as pouring operations in building construction. However, during use, concrete waste is often generated for various reasons. If these wastes are not treated, it will not only cause waste of resources, but also may have certain harm to the environment. Therefore, the recycling of concrete waste is becoming increasingly important. In different construction scenarios, the requirements for concrete recycling equipment are also different. For example, in high-rise building construction, concrete may drip onto window sills during concrete pouring, and it is difficult to clean after it solidifies, and existing equipment may not be able to effectively clean and recycle in such scenarios.

[0003] In the early days, most crushing equipment used a single jaw crusher or hammer crusher, which could only achieve coarse crushing, was difficult to meet the grading requirements of recycled concrete, lacked efficient sorting technology, and affected the strength and durability of recycled concrete. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A concrete recycling device for construction, including a device housing, a feeding component is fixedly connected inside the device housing, a rolling device is fixedly connected to the top of the device housing, a discharge port is fixedly connected to the bottom of the feeding component, and the feeding component is arranged on the side of the rolling device; The feeding component includes a feeding frame, a first arc plate is fixedly connected to the top of the feeding frame, a first guide plate is fixedly connected to the bottom of the first arc plate, a second guide plate is fixedly connected to the bottom of the first guide plate, the sides of the first guide plate and the second guide plate are both fixedly connected to the side of the feeding frame, and the side of the feeding frame is fixedly connected to the inner wall of the device housing. The feeding frame provides support. The arc of the first arc plate cooperates with the corresponding component of the rolling device to form a funnel-shaped crushing cavity structure with a larger upper space and a smaller lower space, so that larger concrete blocks fall under the action of gravity and are gradually crushed into small pieces, thereby reducing the crushing pressure. The side of the first guide plate cooperates with the rolling device to crush the crushed concrete blocks, and the second guide plate guides the crushed concrete out. It realizes the gradual crushing of concrete from large to small, thereby reducing the crushing pressure, avoiding directly crushing large concrete blocks, which may exceed the impact force of the machine, and the process of gradual crushing realizes a streamlined crushing process.

[0005] Preferably, the rolling device includes a fixing plate. A transmission assembly is fixedly connected to the top of the fixing plate. A rolling block is fixedly connected to the bottom of the transmission assembly. An arc-shaped rolling block is fixedly connected to the side of the rolling block. A crushing assembly is fixedly connected to the position below the arc-shaped rolling block on the side of the rolling block. A sliding groove is formed in the side of the rolling block. A sorting assembly is fixedly connected to the inner wall of the sliding groove. A refining assembly is fixedly connected to the bottom of the sorting assembly. The side of the refining assembly is fixedly connected to the inner wall of the equipment housing. The bottom of the sorting assembly is communicated with the discharge port.

[0006] Preferably, the transmission assembly includes a first motor. A first bevel gear is sleeved and fixedly connected to the drive shaft of the first motor. A second bevel gear is meshed with the side of the first bevel gear. A fixed shaft is rotatably connected to the side of the second bevel gear. A flywheel is fixedly connected to the side of the fixed shaft. A connecting rod is rotatably connected to the side of the flywheel through a rotating shaft. The bottom of the connecting rod is rotatably connected to a first fixed seat through a rotating shaft. A fixed bracket is fixedly connected to the top of the first motor. A limiting shaft is fixedly connected to the top inner wall of the fixed bracket. The top of the limiting shaft is fixedly connected to the top of the fixed shaft. The side of the fixed bracket is fixedly connected to the side of the fixing plate. When the rolling block moves upward, the rolling block drives the arc-shaped limiting slide rail to move. The movement of the arc-shaped limiting slide rail compresses the limiting slide rod. The compression of the limiting slide rod drives the first spring to move upward. The upward movement of the first spring drives the third fixed seat to move upward. The upward movement of the third fixed seat drives the sorting frame to rotate upward. The upward rotation of the sorting frame drives the bottom of the pair of fixed rollers to block, thereby reducing the probability of the concrete block directly falling onto the surface of the fixed rollers. When the rolling block descends, the rolling block drives the arc-shaped limiting slide rail to move downward, and the inner wall of the sliding groove presses against the top of the first spring to push the first spring to move downward, thereby driving the sorting frame to move downward, thereby vibrating the concrete on the surface of the fixed rollers. And the surface of the fixed rollers is set to be circular, so that the larger aggregate moves along the surface of the fixed rollers to separate the concrete and the aggregate. The concrete falls through the gap between the fixed rollers. The aggregate is shunted along the surface of the fixed rollers and enters the inner wall of the discharge port for classification and collection. And the back-and-forth vibration of the sorting frame reduces the blockage caused by the aggregate accumulating on the surface of the fixed rollers. The separation of the aggregate and the concrete is realized, and thus the separation of the concrete is realized.

[0007] Preferably, the crushing assembly includes a crushing bottom plate. A conical crushing block is fixedly connected to the top of the crushing bottom plate. A limiting surface is formed at the top of the conical crushing block. The bottom of the crushing bottom plate is fixedly connected to the side of the rolling block.

[0008] Preferably, the classification component includes a classification frame. A classification hole is formed at the top of the classification frame. A fixed roller is fixedly connected to the inner wall of the classification hole. The bottom of the side of the classification frame is rotatably connected to a second fixed seat through a rotating shaft. The top of the side of the classification frame is rotatably connected to a third fixed seat through a rotating shaft. A limiting slide bar is fixedly connected to the top of the third fixed seat. A first spring is sleeved and slidably connected to the side of the limiting slide bar. An arc-shaped limiting slide rail is sleeved and slidably connected to the side of the limiting slide bar. The side of the arc-shaped limiting slide rail is fixedly connected to the inner side of the sliding groove.

[0009] Preferably, the refinement component includes a fixed seat. The side of the fixed seat is rotatably connected to a material guiding outer shell through a rotating shaft. The side of the fixed seat is rotatably connected to the fixed end of a first hydraulic rod through a rotating shaft. The movable end of the first hydraulic rod is rotatably connected to the bottom of the material guiding outer shell through a rotating shaft. A material guiding plate is fixedly connected to the top of the inner wall of the material guiding outer shell. A screening component is slidably connected to the inner wall of the material guiding outer shell. A hydraulic pipe is communicated with the side of the first hydraulic rod. One end of the hydraulic pipe away from the first hydraulic rod is communicated with the fixed end of a second hydraulic rod. A refinement rolling block is fixedly connected to the movable end of the second hydraulic rod. The fixed end of the second hydraulic rod is arranged inside the rolling block and fixedly connected to the rolling block. The side of the fixed seat is fixedly connected to the inner wall of the equipment housing. The top of the screening component is fixedly connected to the bottom of the second fixed seat.

[0010] Preferably, the screening component includes a guiding plate. A concrete screen is fixedly connected to the side of the guiding plate. A guiding sliding groove adapted to the bottom of the refinement rolling block is formed at the top of the concrete screen.

[0011] The present invention provides a concrete recycling device for construction. It has the following beneficial effects: 1. For this concrete recycling device for construction, a material guiding frame is provided for support. The arc of the first arc-shaped plate cooperates with the corresponding component of the rolling device to form a funnel-shaped crushing cavity structure with a larger upper space and a smaller lower space. Larger concrete blocks fall under the action of gravity and are gradually crushed into small pieces, thereby reducing the crushing pressure. The side of the first material guiding plate cooperates with the rolling device to crush the crushed concrete blocks, and the second material guiding plate exports the crushed concrete. It realizes the gradual crushing of concrete from large to small, thereby reducing the crushing pressure and avoiding directly crushing large concrete blocks, which may exceed the impact force of the machine. Moreover, the process of gradual crushing realizes a streamlined crushing process.

[0012] 2. The concrete recycling equipment for construction is provided with a first motor, which gradually decomposes larger concrete blocks into smaller ones. Due to the limiting setting of the limiting surface and the gap setting of the conical crushing blocks, when the concrete is being crushed and rolled, since the strength of the aggregate is higher than that of the concrete and the existence of the gap reduces the rolling pressure on the aggregate, the concrete is crushed and rolled, thereby separating the aggregate from the concrete. The high strength of the aggregate avoids being crushed during the rolling process of the conical crushing blocks, while the concrete on the surface of the aggregate is crushed. The separation of the concrete and the aggregate is achieved, and then classified recycling is carried out, improving the usability of the recycled concrete. Moreover, the crushing and rolling processes rely on the reciprocating up and down action of the rolling blocks, and a certain degree of shaking occurs during the rolling and crushing, thus avoiding blockage during the crushing process. In addition, the gears on both sides of the first bevel gear rotate in opposite directions with the same speed, thereby offsetting the lateral torque caused by the rotation and preventing the machine's stability from decreasing.

[0013] 3. When the rolling block of the concrete recycling equipment for construction moves upward, larger aggregates move along the surface of the fixed roller, thereby separating the concrete from the aggregates. The concrete falls through the gaps between the fixed rollers, and the aggregates are diverted along the surface of the fixed roller and enter the inner wall of the discharge port for classified collection. Moreover, the back-and-forth vibration of the classification frame reduces the blockage caused by the aggregates piling up on the surface of the fixed roller. The separation of the aggregates and the concrete is achieved, thus realizing the separation of the concrete.

[0014] 4. The concrete recycling equipment for construction is provided with fixed rollers. When the concrete falls through the inside of the fixed rollers, it lands on the surface of the concrete screen, sandwiching the concrete between the top of the guide housing and the bottom of the refined rolling block, thereby extruding and crushing the concrete. And it avoids the refined rolling block directly applying pressure to the concrete screen and causing the concrete screen to break, thus further refining the concrete. The refined concrete falls through the concrete screen and enters the top of the guide housing and is guided along the guide plate for collection. The unrefined concrete remains on the top of the concrete screen and waits for the next fall of the rolling block for the next crushing. And due to the existence of vibration, the concrete on the top of the concrete screen undergoes a screening operation through vibration, thus reducing the probability of blockage at the top of the concrete screen.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 3, the present invention provides a technical solution: a concrete recycling device for construction, including an equipment housing 1, a material guiding component 2 fixedly connected inside the equipment housing 1, a rolling device 3 fixedly connected to the top of the equipment housing 1, a discharge port 4 fixedly connected to the bottom of the material guiding component 2, and the material guiding component 2 is arranged on the side of the rolling device 3.

[0019] The equipment housing 1 supports the equipment. The material guiding component 2 guides the concrete blocks and cooperates with the rolling device 3 to perform pre-crushing and classify and export different raw materials. The discharge port 4 exports the raw materials. The rolling device 3 separates the aggregate from the concrete and finely crushes the concrete, so as to separate the aggregate and the concrete as much as possible. And after the concrete is rolled and refined, its performance of repeated utilization is improved. Compared with the traditional recycling device, it avoids crushing the aggregate and causing the aggregate to lose its structural strength, and at the same time further crushes the concrete to avoid insufficient crushing and losing its setting performance.

[0020] The material guiding component 2 includes a material guiding frame 201, a first arc plate 202 fixedly connected to the top of the material guiding frame 201, a first material guiding plate 203 fixedly connected to the bottom of the first arc plate 202, a second material guiding plate 204 fixedly connected to the bottom of the first material guiding plate 203, the sides of the first material guiding plate 203 and the second material guiding plate 204 are fixedly connected to the side of the material guiding frame 201, and the side of the material guiding frame 201 is fixedly connected to the inner wall of the equipment housing 1.

[0021] When the concrete raw materials are introduced, the material guiding frame 201 provides support. The arc of the first arc plate 202 cooperates with the corresponding component of the rolling device 3 to form a funnel-shaped crushing cavity structure with a larger upper space and a smaller lower space, so that the larger concrete blocks fall under the action of gravity and are gradually crushed into small pieces, thereby reducing the crushing pressure. The side of the first material guiding plate 203 cooperates with the rolling device 3 to crush the crushed concrete blocks, and the second material guiding plate 204 exports the crushed concrete. It realizes the gradual crushing of the concrete from large to small, thereby reducing the crushing pressure and avoiding directly crushing the large concrete blocks, which may exceed the impact force of the machine. And the process of gradual crushing realizes a streamlined crushing process.

[0022] Please refer to Figures 1 - 6, the present invention provides a technical solution: The rolling device 3 includes a fixing plate 301, a transmission component 302 is fixedly connected to the top of the fixing plate 301, a rolling block 303 is fixedly connected to the bottom of the transmission component 302, an arc-shaped rolling block 304 is fixedly connected to the side of the rolling block 303, a crushing component 305 is fixedly connected to the side of the rolling block 303 at a position below the arc-shaped rolling block 304, a sliding groove 308 is formed in the side of the rolling block 303, a sorting component 306 is fixedly connected to the inner wall of the sliding groove 308, a refining component 307 is fixedly connected to the bottom of the sorting component 306, the side of the refining component 307 is fixedly connected to the inner wall of the equipment housing 1, and the bottom of the sorting component 306 is communicated with the discharge port 4.

[0023] The transmission component 302 includes a first motor 3021, a first bevel gear 3022 is sleeved and fixedly connected to the drive shaft of the first motor 3021, a second bevel gear 3023 is meshed with the side of the first bevel gear 3022, a fixed shaft 3024 is rotatably connected to the side of the second bevel gear 3023, a flywheel 3025 is fixedly connected to the side of the fixed shaft 3024, a connecting rod 3026 is rotatably connected to the side of the flywheel 3025 through a rotating shaft, a first fixing seat 3027 is rotatably connected to the bottom of the connecting rod 3026 through a rotating shaft, a fixed bracket 3028 is fixedly connected to the top of the first motor 3021, a limiting shaft 3029 is fixedly connected to the top inner wall of the fixed bracket 3028, the top of the limiting shaft 3029 is fixedly connected to the top of the fixed shaft 3024, and the side of the fixed bracket 3028 is fixedly connected to the side of the fixing plate 301.

[0024] The crushing component 305 includes a crushing bottom plate 3051, a conical crushing block 3052 is fixedly connected to the top of the crushing bottom plate 3051, a limiting surface 3053 is formed in the top of the conical crushing block 3052, and the bottom of the crushing bottom plate 3051 is fixedly connected to the side of the rolling block 303.

[0025] The concrete is placed in the position between the arc-shaped rolling block 304 and the first arc-shaped plate 202. The first motor 3021 is started. The drive shaft of the first motor 3021 drives the first bevel gear 3022 to rotate. The rotation of the first bevel gear 3022 drives the second bevel gear 3023 to rotate. The rotation of the second bevel gear 3023 drives the fixed shaft 3024 to rotate. The rotation of the fixed shaft 3024 drives the flywheel 3025 to rotate. The rotation of the flywheel 3025 drives the connecting rod 3026 to rotate. The rotation of the connecting rod 3026 drives the first fixed seat 3027 to move up and down. The first fixed seat 3027 drives the rolling block 303 to move up and down. The movement of the rolling block 303 drives the arc-shaped rolling block 304 to move. The concrete block is crushed by the extrusion force provided by the arc-shaped rolling block 304 and the first arc-shaped plate 202 as the rolling block 303 moves up and down between the arc-shaped rolling block 304 and the first arc-shaped plate 202. Moreover, the arcs of the arc-shaped rolling block 304 and the first arc-shaped plate 202 are different and are set to a structure with a larger upper part and a smaller lower part, so as to perform step-by-step crushing, gradually decompose the larger concrete blocks into smaller concrete blocks. The smaller concrete blocks pass through the surface of the conical crushing block 3052 under the action of gravity. The conical crushing block 3052 cooperates with the concrete between the conical crushing block 3052 and the first guide plate 203 under the driving action of the rolling block 303, so as to crush the smaller concrete. Due to the limit setting of the limit surface 3053 and the gap setting of the conical crushing block 3052, when the concrete is rolled and crushed, since the strength of the aggregate is higher than that of the concrete and the existence of the gap reduces the rolling pressure on the aggregate, the concrete is crushed and rolled, so as to realize the separation of the aggregate and the concrete. The high strength of the aggregate avoids crushing the aggregate during the rolling process of the conical crushing block 3052, and at the same time crushes the concrete on the surface of the aggregate. The separation of the concrete and the aggregate is realized, so as to carry out classified recycling, improve the usability of the recycled concrete, and the crushing and rolling processes rely on the up-and-down reciprocating action of the rolling block 303, and a certain degree of shaking occurs during the rolling and crushing, so as to avoid blockage during the crushing process. Moreover, the rotation directions of the gears on both sides of the first bevel gear 3022 are opposite and the rotation speeds are synchronized, so as to offset the lateral moment caused by the torque brought by the rotation and prevent the machine stability from decreasing.

[0026] Please refer to Figures 1 - 7, the present invention provides a technical solution: the classification component 306 includes a classification frame 3061, a classification hole 3062 is opened at the top of the classification frame 3061, a fixed roller 3063 is fixedly connected to the inner wall of the classification hole 3062, the bottom of the side surface of the classification frame 3061 is rotatably connected to a second fixed seat 3064 through a rotating shaft, the top of the side surface of the classification frame 3061 is rotatably connected to a third fixed seat 3065 through a rotating shaft, a limiting slide bar 3066 is fixedly connected to the top of the third fixed seat 3065, a first spring 3067 is sleeved and slidably connected to the side surface of the limiting slide bar 3066, and an arc-shaped limiting slide rail 3068 is sleeved and slidably connected to the side surface of the limiting slide bar 3066. The side surface of the arc-shaped limiting slide rail 3068 is fixedly connected to the side surface of the inner wall of the sliding groove 308.

[0027] When the rolling block 303 moves upward, the rolling block 303 drives the arc-shaped limiting slide rail 3068 to move. The movement of the arc-shaped limiting slide rail 3068 compresses the limiting slide bar 3066. The compression of the limiting slide bar 3066 drives the first spring 3067 to move upward. The upward movement of the first spring 3067 drives the third fixed seat 3065 to move upward. The upward movement of the third fixed seat 3065 drives the classification frame 3061 to rotate upward. The upward rotation of the classification frame 3061 drives the fixed roller 3063 to block the bottom of the crushing component 305, thereby reducing the probability of the concrete block directly falling onto the surface of the fixed roller 3063. When the rolling block 303 moves downward, the rolling block 303 drives the arc-shaped limiting slide rail 3068 to move downward, and the inner wall of the sliding groove 308 presses against the top of the first spring 3067 to push the first spring 3067 to move downward, thereby driving the classification frame 3061 to move downward, so as to shake the concrete on the surface of the fixed roller 3063. And the surface of the fixed roller 3063 is set to be circular, so that the larger aggregates move along the surface of the fixed roller 3063 to separate the concrete and the aggregates. The concrete falls through the gap between the fixed rollers 3063. The aggregates are shunted along the surface of the fixed roller 3063 and enter the inner wall of the discharge port 4 for classified collection. And the back-and-forth vibration of the classification frame 3061 reduces the blockage caused by the aggregates piling up on the surface of the fixed roller 3063. The separation of the aggregates and the concrete is realized, and thus the separation of the concrete is realized.

[0028] Please refer to Figures 1 - 9, the present invention provides a technical solution: The refinement component 307 includes a fixed seat 3071. The side of the fixed seat 3071 is rotatably connected to a material guiding housing 3072 through a rotating shaft. The side of the fixed seat 3071 is rotatably connected to the fixed end of a first hydraulic rod 3073 through a rotating shaft. The movable end of the first hydraulic rod 3073 is rotatably connected to the bottom of the material guiding housing 3072 through a rotating shaft. The top of the inner wall of the material guiding housing 3072 is fixedly connected to a material guiding plate 3074. A screening component 3075 is slidably connected to the inner wall of the material guiding housing 3072. A hydraulic pipe 3076 is communicated with the side of the first hydraulic rod 3073. One end of the hydraulic pipe 3076 away from the first hydraulic rod 3073 is communicated with the fixed end of a second hydraulic rod 3077. The movable end of the second hydraulic rod 3077 is fixedly connected to a refinement rolling block 3078. The fixed end of the second hydraulic rod 3077 is arranged inside the rolling block 303 and fixedly connected to the rolling block 303. The side of the fixed seat 3071 is fixedly connected to the inner wall of the equipment housing 1. The top of the screening component 3075 is fixedly connected to the bottom of the second fixed seat 3064.

[0029] The screening component 3075 includes a guiding plate 30751. The side of the guiding plate 30751 is fixedly connected to a concrete screen 30752. A guiding chute 30753 adapted to the bottom of the refinement rolling block 3078 is provided at the top of the concrete screen 30752.

[0030] When the concrete falls through the inside of the fixed roller 3063, the concrete lands on the surface of the concrete screen 30752. When the rolling block 303 descends, the descent of the rolling block 303 drives the second hydraulic rod 3077 to descend. As the movable end of the second hydraulic rod 3077 descends and gradually receives the pressure from the large pieces of concrete, an upward pressure is generated on the second hydraulic rod 3077, thereby driving the contraction of the movable end of the second hydraulic rod 3077. The contraction of the movable end of the second hydraulic rod 3077 generates pressure on the liquid inside the fixed end. The liquid inside the fixed end of the second hydraulic rod 3077 enters the inside of the first hydraulic rod 3073 through the hydraulic pipe 3076, thereby driving the first hydraulic rod 3073 to extend. The extension of the first hydraulic rod 3073 drives the material guiding housing 3072 to rotate along the rotation center on the side of the fixed seat 3071, so that the bottom of the inner wall of the material guiding housing 3072 closely adheres to the bottom of the concrete screen 30752 under the driving action of the first hydraulic rod 3073. At this time, the refining rolling block 3078 descends and slides along the guiding chute 30753. Since the movement processes of the refining rolling block 3078 and the first hydraulic rod 3073 are synchronous, the concrete is clamped between the top of the material guiding housing 3072 and the bottom of the refining rolling block 3078, thereby extruding and crushing the concrete, and preventing the refining rolling block 3078 from directly applying pressure to the concrete screen 30752 and causing the concrete screen 30752 to break, thereby further refining the concrete. The refined concrete falls through the concrete screen 30752 and enters the top of the material guiding housing 3072 and is guided along the guide plate 3074 for collection. The unrefined concrete remains on the top of the concrete screen 30752 and waits for the next descent of the rolling block 303 for the next crushing. And due to the existence of vibration, the concrete on the top of the concrete screen 30752 is sieved through vibration, thereby reducing the probability of blockage at the top of the concrete screen 30752.

[0031] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the scope of protection of the present invention.
