[0002] During large-scale construction projects such as subways, tunnels, and viaducts, as well as building demolition, a large number of support beams and columns are retired and scrapped. These beams and columns contain a large amount of steel and concrete, and most existing support beams and columns have both circular and longitudinal reinforcement, which gives them high mass and structural strength, making them difficult to break.

[0003] The existing Chinese patent application document with publication number CN114377829A discloses a system for recycling and reusing steel bars in concrete beams, including a feeder table, a crusher, a roller crusher, and a main steel bar cutter; the feeder table, crusher, roller crusher, and main steel bar cutter are arranged in a straight line in sequence; the feeder table is provided with a driving device; the crusher is provided with a crushing mechanism to crush the concrete beam to be processed; the rolling device is a rolling knife that can move vertically back and forth; a main steel bar cutter is provided behind the roller crusher, and the main steel bar cutter is a gantry shearing machine, which moves intermittently to cut the main steel bars into a fixed length and output them.

[0004] In the existing technology, the concrete beams in the steel bar recycling and reuse system in concrete beams are transported by conveyor belts, and large beams and columns are usually placed on the conveyor belts by cranes. If the second large beam and column is placed directly on the conveyor belt, it will affect the crushing effect of the first large beam and column, and the weighing capacity of the conveyor belt is high; if the second large beam and column is placed on the conveyor belt after the first large beam and column is crushed, the crushing efficiency will be reduced, and there is room for improvement. Summary of the Invention

[0005] In view of the defects in the prior art, the purpose of the present invention is to provide a secondary feeding system for a beam breaker and a static pressure beam breaker.

[0006] According to the present invention, a secondary feeding system for a beam crusher is provided, comprising a feeding bracket, a roller, a rotating arm and a rotating drive member, wherein a plurality of the rollers are installed at intervals on the upper part of the feeding bracket, and an upward-extending rotating bracket is provided on the upper part of one side of the feeding bracket, the rotating arm is rotatably connected to the rotating bracket, and the lower part of the rotating arm is transmission-connected to the rotating drive member, and the rotating drive member drives the rotating arm to switch between a first state and a second state; in the first state, the upper part of the rotating arm extends obliquely upward from the connection with the rotating bracket in a direction away from the roller, and the height of the highest point of the rotating arm is higher than the height of the roller; in the second state, the upper part of the rotating arm extends obliquely downward from the connection with the rotating bracket in a direction away from the roller, and the height of the highest point of the rotating arm is lower than the height of the roller.

[0007] Preferably, both ends of the drum are rotatably connected to the loading bracket via bearings.

[0008] Preferably, the heights of the plurality of rollers decrease sequentially from being away from the rotating bracket to being close to the rotating bracket.

[0009] Preferably, in the first state, a receiving plane is formed on the upper portion of the rotating arm.

[0010] Preferably, when the material to be crushed is placed into the loading bracket, one end of the material to be crushed extends from one end of the rotating arm.

[0011] According to the present invention, a static beam breaker further includes a conveying mechanism and a crushing mechanism. The conveying mechanism conveys materials into the crushing mechanism, and the feeding system is arranged on the side of the conveying mechanism away from the crushing mechanism; when the feeding system is in a first state, one end of the material to be crushed extends from the feeding system to the upper part of the conveying mechanism; when the feeding system is in a second state, one end of the material to be crushed is placed on the conveying mechanism.

[0012] Preferably, the maximum height of the plurality of rollers is higher than the height of the conveying mechanism.

[0013] Preferably, guide mechanisms are provided on both sides of the conveying mechanism, and the guide mechanisms include a column, a guide plate and an adjustment component; the column is fixed, the guide plate includes a guide surface, the adjustment component is provided between the column and the guide plate, and the adjustment component adjusts the spacing distance between the guide mechanisms that are relatively arranged on both sides of the conveying mechanism.

[0014] Preferably, the adjustment assembly includes a guide groove and a fixing bolt, the guide plate slides along the length direction of the guide groove, and the fixing bolt presses the guide plate onto the column.

[0015] Preferably, the conveying mechanism includes a crawler mechanism.

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

[0017] 1. The present invention places the second large beam to be crushed on the loading bracket first. When the beam crusher crushes most of the first large beam, the rotary drive member is started to drive the rotating arm to rotate along the rotating connection between the rotating arm and the rotating bracket. Due to the height setting of the roller and the rotating arm, the second large beam to be crushed is tilted and pressed onto the conveying mechanism. There is a sufficiently large friction between the second large beam to be crushed and the conveying mechanism, so that the second large beam to be crushed moves with the conveying mechanism under the action of the conveying mechanism, which helps to improve the loading efficiency and thus improve the crushing efficiency.

[0018] 2. The present invention ensures sufficient friction between the beams and the conveying mechanism by setting the height of the roller, ensuring that the beams move with the conveying mechanism.

[0019] 3. The present invention uses a shearing device to cut the transverse reinforcement of large concrete reinforced beams and columns, and then uses a crushing device to crush the concrete of the large concrete beams and columns. The shearing device and the crushing device are both used to crush the sides of large concrete reinforced beams and columns, and the crushing is performed directly on the conveying mechanism. The crushed fragments and longitudinal reinforcement are respectively conveyed to the fragment recovery mechanism and the separation and turning mechanism through the conveying mechanism to recycle the crushed materials, which helps to improve the crushing efficiency and crushing effect.

[0033] DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0035] like Figure 1 As shown, a secondary loading system for a beam crusher provided according to the present invention includes a loading bracket 301, a roller 302, a rotating arm 303 and a rotating drive member 304. A plurality of rollers 302 are installed at intervals on the upper part of the loading bracket 301. An upwardly extending rotating bracket 305 is provided on the upper part of one side of the loading bracket 301. The rotating arm 303 is rotatably connected to the rotating bracket 305. The lower part of the rotating arm 303 is transmission-connected to the rotating drive member 304. The rotating drive member 304 drives the rotating arm 303 to switch between the first state and the second state.

[0036] In the first state, the upper portion of the rotating arm 303 extends obliquely upward from the connection point with the rotating bracket 305 in a direction away from the drum 302 , and the highest point of the rotating arm 303 is higher than the height of the drum 302 .

[0037] In the second state, the upper portion of the rotating arm 303 extends obliquely downward from the connection point with the rotating bracket 305 in a direction away from the drum 302 , and the height of the highest point of the rotating arm 303 is lower than the height of the drum 302 .

[0038] Specifically, both ends of the roller 302 are rotatably connected to the feeding bracket 301 through bearings. The heights of the rollers 302 decrease in sequence from being away from the rotating bracket 305 to being close to the rotating bracket 305.

[0039] In the first state, a receiving plane is formed on the upper portion of the rotating arm 303. When the material to be crushed is placed into the loading bracket 301, one end of the material to be crushed extends from one end of the rotating arm 303.

[0040] The rotary drive member 304 of the present application is a cylinder, the cylinder body of which is hingedly connected to the loading bracket 301. By first placing the second large beam to be crushed on the loading bracket 301, and once the beam crusher has crushed most of the first large beam, the rotary drive member 304 is activated, driving the rotating arm 303 to rotate along the pivotal connection between the rotating arm 303 and the rotating bracket 305, placing one end of the second large beam to be crushed onto the conveyor mechanism 101. At this point, due to the height setting of the roller 302 and the rotating arm 303, the second large beam to be crushed is tilted and pressed against the conveyor mechanism 101. There is sufficient friction between the second large beam to be crushed and the conveyor mechanism 101, causing the second large beam to move with the conveyor mechanism 101 under the action of the conveyor mechanism 101.

[0041] like Figure 1 and Figure 2 As shown, a static beam crusher according to the present invention further includes a conveying mechanism 101 and a crushing mechanism 102. The conveying mechanism 101 conveys material into the crushing mechanism 102, and a feeding system is disposed on a side of the conveying mechanism 101 away from the crushing mechanism 102. When the feeding system is in a first state, one end of the material to be crushed extends from the feeding system to the upper portion of the conveying mechanism 101. When the feeding system is in a second state, one end of the material to be crushed is placed on the conveying mechanism 101. The maximum height of the multiple rollers 302 is higher than that of the conveying mechanism 101.

[0042] More specifically, it includes a conveying mechanism 101, a crushing mechanism 102, a separation and turning mechanism 103, a crushed material recovery mechanism 104 and a control mechanism.

[0043] The conveying mechanism 101 transports the material to be crushed to the crushing mechanism 102, and then transports the crushed material to the crushing mechanism 102. The crushing mechanism 102 includes a shearing device 201 for shearing the ring reinforcement and a crushing device 202 for crushing the concrete. The separation and turnover mechanism 103 is spaced apart from the conveying end of the conveying mechanism 101 and transports the longitudinal reinforcement to a designated location. The debris recovery mechanism 104 is used to receive debris that falls between the conveying mechanism 101 and the separation and turnover mechanism 103 and transports it to a designated location.

[0044] Under the action of the control mechanism, the conveying mechanism 101 conveys the material to be crushed to the crushing mechanism 102, and the transverse reinforcement of the material to be crushed is first cut by the shearing device 201, and then the concrete is crushed by the crushing device 202. After that, the conveying mechanism 101 conveys the crushed material to the separation and turning mechanism 103, and the crushed material falls from the gap between the conveying mechanism 101 and the separation and turning mechanism 103 to the crushed material recovery mechanism 104 and is transported to the designated position by the crushed material recovery mechanism 104. The longitudinal reinforcement moves to the separation and turning mechanism 103 and is transported to the designated position by the separation and turning mechanism 103.

[0045] Specifically, the conveying mechanism 101 includes devices with conveying capabilities such as crawlers and conveyor belts. The technical solution of this application preferably uses crawlers, which have sufficient load-bearing capacity to adapt to the weight of large concrete beams and columns.

[0046] like Figure 2 and Figure 3 As shown, the shearing device 201 includes a shearing frame 2011, a front scissor 2012, and a front cylinder 2013. The front scissor 2012 is hinged to the shearing frame 2011, the cylinder body of the front cylinder 2013 is hinged to the shearing frame 2011, and the telescopic rod of the front cylinder 2013 is hinged to the front scissor 2012. The hinge axes of the front scissor 2012 and the shearing frame 2011, the hinge axes of the cylinder body of the front cylinder 2013 and the shearing frame 2011, and the hinge axes of the telescopic rod of the front cylinder 2013 and the front scissor 2012 are all parallel to each other. When the piston rod of the front cylinder 2013 retracts, the front scissor 2012 rotates and opens along the hinge axis between the front scissor 2012 and the shearing frame 2011. When the piston rod of the front cylinder 2013 extends, the front scissor 2012 rotates along the hinge axis between the front scissor 2012 and the shearing frame 2011 to cut.

[0047] Two sets of front shears 2012 are arranged opposite each other on the shear frame 2011. Multiple front shears 2012 are arranged alternately from top to bottom in the two sets of front shears 2012, and the number of front shears 2012 in each set of front shears 2012 is the same. Each set of front shears 2012 is provided with a corresponding front hydraulic cylinder 2013. The distance between the two sets of front shears 2012 allows: when the two sets of front shears 2012 are fully opened, the material to be crushed enters between the two sets of front shears 2012 along with the conveying mechanism 101, and both sets of front shears 2012 can simultaneously shear the material to be crushed between the two sets of front shears 2012. The front shears 2012 within the two sets of front shears 2012 that are arranged opposite each other move simultaneously, while the front shears 2012 within the two sets of front shears 2012 that are not arranged opposite each other move simultaneously or in a time-sharing manner.

[0048] More specifically, each front scissors 2012 includes multiple shearing teeth, and each front scissors 2012 rotates from outside to inside under the action of the front cylinder 2013 to shear the side of the material to be crushed located between the two groups of front scissors 2012 until the ring ribs of the material to be crushed are cut off.

[0049] like Figure 2 、 Figure 3 as well as Figure 4 As shown, the crushing device 202 includes a crushing frame 2021, rear scissors 2022 and a driving device. Two groups of rear scissors 2022 are relatively arranged on the crushing frame 2021. The driving device drives the two groups of rear scissors 2022 to move closer to or away from each other. The driving device is a rear cylinder 2023. Any group of rear scissors 2022 is driven by one or more rear cylinders 2023, and multiple rear cylinders 2023 driving the same rear scissors 2022 move simultaneously.

[0050] The rear shears 2022 include multiple crushing cones that press against the sides of the material to be crushed, crushing it. Because the ring reinforcement of the material being crushed by the crushing device 202 has already been sheared by the shearing device 201, the crushing device 202 mainly acts on the concrete, crushing the concrete and separating the longitudinal reinforcement from the concrete.

[0051] To meet the requirements of crushing large concrete beams and columns of varying sizes, the height of the rear shears 2022 is greater than the height of the material to be crushed. During crushing, the material is located on the conveying mechanism 101, that is, at the bottom of the rear shears 2022. At this time, the force exerted by the material to be crushed on the rear shears 2022 causes the movement of the rear shears 2022 to be unbalanced. In order to balance the force exerted by the material to be crushed on the rear shears 2022, the present application connects two rear oil cylinders 2023 along the height direction to drive the two rear shears 2022. Furthermore, the tops of the two rear shears 2022 are provided with guide sleeves 2024, and the crushing frame 2021 is provided with guide rods 2025. The guide sleeves 2024 at the tops of the two oppositely arranged rear shears 2022 are both mounted on the same guide rod 2025 and slide in conjunction with it. The limiting action of the guide sleeves 2024 balances the upper portion of the rear shears 2022, improving the stability of the movement of the two sets of rear shears 2022.

[0052] like Figure 2 and Figure 5As shown, the separation and flipping mechanism 103 includes a flip frame 1031, a flip platform 1032, and a flip cylinder 1033. The flip platform 1032 is mounted on the flip frame 1031. One side of the flip platform 1032 is rotatably connected to the flip frame 1031. The cylinder body of the flip cylinder 1033 is mounted on the flip frame 1031, and the piston rod of the flip cylinder 1033 is hingedly connected to the flip frame 1032. When the piston rod of the flip cylinder 1033 extends, the flip platform 1032 rotates and flips along the rotation axis of the flip platform 1032 and the flip frame 1031. When the piston rod of the flip cylinder 1033 retracts, the flip platform 1032 rotates and falls back to the flip frame 1031 along the rotation axis of the flip platform 1032 and the flip frame 1031. During the overall crushing process of the material to be crushed, the longitudinal reinforcement moves to the turning table 1032. After the crushing is completed, the turning table 1032 is driven to rotate by the turning cylinder 1033 to transport the longitudinal reinforcement to the designated position, and then transported by the transfer vehicle for reuse.

[0053] Furthermore, a motion frame is provided on the turning frame 1031, which drives the turning platform 1032 to move toward or away from the conveying mechanism 101. The motion frame adjusts the distance between the turning platform 1032 and the conveying end of the conveying mechanism 101 through a ball screw pair, which helps to improve the applicability of the system.

[0054] The scrap recovery mechanism 104 includes a scrap recovery conveyor belt. The conveying starting point of the scrap recovery conveyor belt is located below the gap formed by the conveying mechanism 101 and the separation and turnover mechanism 103. A buffer roller 1041 is provided above the conveying starting point of the scrap recovery conveyor belt. The scraps are buffered by the buffer roller 1041 and fall onto the scrap recovery conveyor belt, which then transports them to a designated location.

[0055] When the crushed materials on the conveying mechanism 101 move with the conveying mechanism 101 to the conveying end of the conveying mechanism 101 and fall onto the crushed materials recovery mechanism 104, the control mechanism starts the crushed materials recovery mechanism 104. When the crushing mechanism 102 stops working, the control mechanism starts the separation and flipping mechanism 103.

[0056] like Figure 2 and Figure 6 As shown, the conveying mechanism 101 further includes one or more guide mechanisms 105, one set on each side of the conveying mechanism 101. The guide mechanisms 105 on either side of the conveying mechanism 101 limit the swing range of the material to be crushed on the conveying mechanism 101. Specifically, the guide mechanisms 105 include columns 1051, guide plates 1052, and an adjustment assembly. The columns 1051 are fixed, the guide plates 1052 include a guide surface, and the adjustment assembly is disposed between the columns 1051 and the guide plates 1052. The adjustment assembly adjusts the distance between the guide mechanisms 105 disposed opposite each other on either side of the conveying mechanism 101.

[0057] When the conveying mechanism 101 drives the material to be crushed toward the guide plate 1052, the guiding surface adjusts the posture of the material on the conveying mechanism 101, allowing the material to move stably with the conveying mechanism 101. When one end of the material enters the crushing mechanism 102 for crushing, it generates a significant crushing force, often causing the tail of the cement beam to swing, thus posing a safety hazard. The guide mechanism 105 confines the material on the crawler track to a certain space, preventing the tail of the material from swinging and improving the stability of the crushing process.

[0058] The adjustment assembly includes a guide slot 1053 and a fixing bolt 1054. The guide plate 1052 slides along the length of the guide slot 1053, and the fixing bolt 1054 presses the guide plate 1052 against the column 1051. Using the adjustment assembly to adjust the distance between the guide mechanisms 105 disposed opposite each other on both sides of the conveying mechanism 101 helps improve the overall applicability of the system.

[0059] The crushing mechanism 102 further includes a dust removal spray device 106, which is provided with nozzles at the inlet and outlet of the crushing mechanism 102. The nozzles can spray atomized spray, the main function of which is to eliminate dust and help meet environmental protection standards.

[0060] The water inlet of the dust removal spray system can be equipped with different high-pressure water sources. The high-pressure water passes through the water inlet, the main water pipe, and the high-pressure nozzle. The water sprayed out by the high-pressure nozzle is mist water. The generated mist water makes the dust floating in the air fall into the conveyor belt and the ground, thereby avoiding the dust from flying. The fixed plate can be flexibly fixed to various parts of the static pressure beam breaker.

[0061] like Figure 2 and Figure 7 As shown, the loading mechanism includes a gantry 107, which is equipped with a travel motor and a lifting motor. Gantry 107 lifts and moves beams and columns in the static beam crusher. Its length, width, and height can accommodate the lifting and movement of beams and columns of varying specifications. The lifting motor drives the workpiece up and down via the lifting tool, while the travel motor drives the workpiece in longitudinal reciprocating motion within the guide rails. The gantry 107 allows the crushed parts to be easily and freely placed on the crawler tracks through lifting and movement. This design of the gantry 107 reduces the lifting and waiting time of traditional equipment.

[0062] like Figure 2 and Figure 8 As shown, according to the present invention, a crushing method for beams and columns is provided, and the crushing method includes the following steps:

[0063] Step S1 : placing the material to be crushed on the conveying mechanism 101 ; the conveying mechanism 101 brings the material to be crushed into the crushing mechanism 102 and stops; the crushing mechanism 102 includes a shearing device 201 and a crushing device 202 .

[0064] Step S2: The two sets of front shears 2012 of the shearing device 201 rotate to shear the material to be crushed, and the two sets of rear shears 2022 of the crushing device 202 move away from or close to each other to crush the material to be crushed.

[0065] When the rotation range of the two sets of front scissors 2012 reaches the preset value, and the relative movement distance of the two sets of rear scissors 2022 reaches the preset value or the two sets of rear scissors 2022 are in the open standby state, the conveying mechanism 101 starts and drives the material to be crushed to move the preset distance and then stops, repeating step S2.

[0066] It should be noted that the scraps on the conveying mechanism 101 move with the conveying mechanism 101 to the conveying end of the conveying mechanism 101 and fall onto the scrap recovery mechanism 104, which then conveys the scraps to a designated location. The longitudinal strands of the material move to the separation and flipping mechanism 103.

[0067] The preset values of the rotation range of the two sets of front scissors 2012, the preset values of the movement distance of the two sets of rear scissors 2022, and the preset distance that the conveying mechanism 101 drives the material to be crushed to move are all input into the control mechanism through the computer.

[0068] Step S3: After the crushing is completed, the crushing device 202 stops, and the separation and flipping mechanism 103 flips the longitudinal reinforcement to a designated position.

[0069] like Figure 2 and Figure 9 As shown, the conveying mechanism 101 includes a crawler mechanism. During the beam crushing process, the crawler's travel speed and the distance traveled each time determine the crushing speed and efficiency. To achieve an optimal travel distance each time, a first light sensing system 203 is installed at the crawler's sprocket to control the crawler's movement. The first light sensing system 203 includes a cursor disk 2031 and a first cursor source 2032. The cursor disk 2031 is coaxially fixed to the sprocket. A plurality of cursor teeth are evenly spaced around the circumference of the cursor disk 2031. Information from each cursor tooth on the cursor disk 2031 passing through the cursor source is captured by the control mechanism.

[0070] Its working principle is: the light emitted by the first cursor source 2032 is read by the relatively moving cursor, and each interval is read and memorized by the PLC programmable digital controller, and then the speed and distance of each crawler are set through the display and computer.

[0071] like Figure 2 and Figure 10As shown, each front scissor 2012 of the shearing device 201 is driven to rotate by a front cylinder 2013, which is equipped with a second optical sensing system 204. The second optical sensing system 204 includes a first cylinder cursor 2041 and a second cursor source 2042. The first cylinder cursor 2041 is fixed to the main body of the front cylinder 2013, while the second cursor source 2042 is fixed to the piston rod of the front cylinder 2013. The displacement information of the first cylinder cursor 2041 relative to the second cursor source 2042 is captured by a control mechanism. The operating principle is as follows: When the cylinder moves, it drives the cylinder guide rod, thereby moving the first cylinder cursor 2041. When the second cursor source 2042 and the first cylinder cursor 2041 move relative to each other, each distance of movement is read and stored by the PLC programmable digital controller. The PLC then uses the display and computer to set the speed and distance of each movement of the front cylinder 2013, and therefore the front scissors 2012.

[0072] like Figure 2 and Figure 11 As shown, each rear shear 2022 of the crushing device 202 is driven by a rear cylinder 2023, which is equipped with a third optical sensing system 205. The third optical sensing system 205 comprises a second cylinder cursor 2051 and a third cursor source 2052. The second cylinder cursor 2051 is fixed to the rear cylinder 2023, while the third cursor source 2052 is fixed to the piston rod of the rear cylinder 2023. The displacement information of the second cylinder cursor 2051 relative to the third cursor source 2052 is captured by a control mechanism. Movement of the cylinder drives the cylinder guide rod, thereby causing the third cursor source 2052 to move relative to the second cylinder cursor 2051. Each movement is recorded and memorized by the PLC programmable digital controller. The speed and distance of each movement of the rear cylinder 2023, and therefore the rear shear 2022, are then set via a display and computer.

[0073] The system also includes a monitoring system 108, which captures image information from the shearing device 201 and the crushing device 202 and transmits it to the control mechanism. The front camera of monitoring system 108 is used to monitor the optimal position of the front crushing beam, the movement trajectory of the shears during the shearing process, and the degree of crushing. The rear camera of monitoring system 108 is used to monitor the optimal position of the rear crushing beam, the movement trajectory during the shearing and crushing process, and the degree of crushing.

[0074] Those skilled in the art will appreciate that, in addition to implementing the system and its various devices, modules, and units provided by the present invention in purely computer-readable program code, it is entirely possible to implement the same functions of the system and its various devices, modules, and units provided by the present invention in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps.
