[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, a garbage crushing and recycling device for road and bridge construction includes a vehicle body 1, and an on-site crushing mechanism 2 and a transfer mechanism 3 are arranged at the forward end of the vehicle body 1. The feeding end of the transfer mechanism 3 is arranged opposite to the on-site crushing mechanism 2, and the discharging end of the transfer mechanism 3 is arranged opposite to the vehicle-mounted crushing mechanism 4 on the vehicle body 1. The discharging end of the vehicle-mounted crushing mechanism 4 is connected to a sand making machine 5 on the vehicle body 1, and the discharging end of the sand making machine 5 is provided with an adjustable discharging mechanism 6.

[0023] like Figure 2 - Figure 4 As shown, the in-situ crushing mechanism 2 comprises a mounting frame 21 , on which a detection unit 22 , a cutting unit 23 , a breaking unit 24 and a hammering unit 25 are sequentially mounted.

[0024] The detection unit 22 is used to collect road surface images and internal steel bar positions. The detection unit 22 includes a plurality of transmission gears 221 arranged in parallel on the mounting frame 21. Adjacent transmission gears 221 are meshed with each other. An extension arm 222 is installed on the transmission gear 221. In this embodiment, an extension arm 222 is installed for every other transmission gear 221. The number of extension arms 222 can be increased or decreased according to actual detection density requirements. A metal detector 223 and an image collector 224 are installed on the extension arm 222. One of the transmission gears 221 is connected to a detection drive motor 225 through a gear. The detection drive motor 225 is installed on the mounting frame 21; the image collector 224, the metal detector 223 and the detection drive motor 225 are all electrically connected to the control terminal.

[0025] The detection drive motor 225 is started to make the transmission gear 221 rotate within a set angle range, thereby realizing image acquisition and metal detection of the road surface, which is convenient for subsequent regulation.

[0026] When the metal detector 223 detects the presence of steel bars, the cutting unit 23 is activated to preliminarily cut the road surface and then crush it. The cutting unit 23 includes a spacing shaft 231 and a plurality of mounting blocks 232 arranged in parallel on the spacing shaft 231. The slider on the side of the mounting block 232 is arranged in a spiral spacing groove 233 opened on the circumferential side of the spacing shaft 231. Figure 5As shown, there are two spiral pitch-adjusting grooves 233 on the pitch-adjusting shaft 231 and they are mirror-imaged, one end of the pitch-adjusting shaft 231 is connected to a cutting pitch-adjusting drive motor 234, the cutting pitch-adjusting drive motor 234 is mounted on the mounting frame 21, the mounting block 232 is slidably arranged on the guide shaft 235, a cutting lifting hydraulic cylinder 236 is arranged at the bottom of the mounting block 232, a cutting angle adjustment drive motor 237 is installed at the telescopic end of the cutting lifting hydraulic cylinder 236, and the output shaft of the cutting angle adjustment drive motor 237 is connected to a cutting machine 238; the cutting pitch-adjusting drive motor 234, the cutting lifting hydraulic cylinder 236, the cutting angle adjustment drive motor 237 and the cutting machine 238 are all electrically connected to the control terminal.

[0027] According to the detected position of the steel bars, the cutting distance adjustment drive motor 234 is started, so that the mounting block 232, under the action of the slider and the guide shaft 235 in the spiral distance adjustment groove 233, drives several cutting lifting hydraulic cylinders 236 to move closer or farther at equal intervals. Since the steel bars are generally arranged at equal intervals, the present application adopts an equal-interval adjustment mechanism to adjust each cutting position. After the adjustment is completed, the cutting lifting hydraulic cylinder 236 and the cutting angle adjustment drive motor 237 are started, so that the cutting machine 238 cuts the ground.

[0028] After the cutting is completed, further crushing is required. The crushing unit 24 includes a guide frame 241. Figure 6 As shown, a fixing groove 242 is provided on the inner side of the guide frame 241, and a clamping plate 243 is provided in the fixing groove 242. Both ends of the clamping plate 243 are arranged in the through hole of the guide frame 241, wherein a first wedge block 244 is provided at one end of the clamping plate 243, and the first wedge block 244 is arranged opposite to the second wedge block 245, and the second wedge block 245 is connected to a connecting frame 246, and the connecting frame 246 is connected to a tightening rack 247, and the tightening rack 247 is meshed with a tightening gear 248, and the tightening gear 248 is meshed with a position rack 249, and the position rack 249 and the tightening rack 247 are both slidably arranged on the guide frame 241, and a motor screw structure 2410 is provided on one side of the guide frame 241. A moving seat 2411 is provided, and an adsorption electromagnet 2412 is provided on the moving seat 2411. The adsorption electromagnet 2412 is arranged opposite to a plurality of breaking and lifting hydraulic cylinders 2413 arranged in parallel in the guide frame 241. The fixing plate 361 on the side of the breaking and lifting hydraulic cylinder 2413 is arranged in the fixing groove 242. A pneumatic pick 2414 is provided at the telescopic end of the breaking and lifting hydraulic cylinder 2413. A breaking angle adjustment drive motor 2415 is provided at one end of the guide frame 241. The breaking angle adjustment drive motor 2415 is arranged on the mounting frame 21. The motor screw structure 2410, the adsorption electromagnet 2412, the breaking and lifting hydraulic cylinder 2413, the pneumatic pick 2414 and the breaking angle adjustment drive motor 2415 are all electrically connected to the control terminal.

[0029] Since the positions of ground defects such as cracks, potholes or bulges on the road surface are irregular, the operator adjusts the breaking unit 24 according to the actual road conditions collected. First, the position of the pneumatic pick 2414 is adjusted according to the defect position, and the motor screw structure 2410 is started to make the moving seat 2411 reach the position of the corresponding breaking lifting hydraulic cylinder 2413. After the adsorption electromagnet 2412 is energized, the corresponding breaking lifting hydraulic cylinder 2413 is grasped. After moving to the set position, the adsorption electromagnet 2412 is de-energized to release the breaking lifting hydraulic cylinder 2413. After multiple breaking lifting hydraulic cylinders 2413 have adjusted their positions in turn, the motor screw structure 2410 makes the moving seat 2411 return to the initial position, squeezes the rack 249 into place, and the tightening gear 248 rotates, thereby driving the tightening rack 247 to move toward the inside of the guide frame 241, such as Figure 7 As shown, the first wedge block 244 squeezes the second wedge block 245, so that the clamping plate 243 moves downward, clamping a plurality of breaking lifting hydraulic cylinders 2413, so as to fix the positions of the plurality of breaking lifting hydraulic cylinders 2413. Then the angle is adjusted, and the inclination angle of the pneumatic pick 2414 is determined according to the actual hardness of the road surface and the crack cylinder. When the road surface is intact and relatively hard, the pneumatic pick 2414 uses vertical hammering to provide the maximum impact force and quickly and effectively destroy the material structure. When the road surface material is relatively soft or there are already cracks in the area, the pneumatic pick 2414 uses a 45°-60° inclination angle to hammer, which can reduce the rebound force and transfer the energy more evenly to the inside of the material, which helps to gradually expand the cracks without causing excessive vibration.

[0030] After being broken, the concrete block is large and needs to be further broken by a hammer unit 25. The hammer unit 25 includes a plurality of hammer lifting hydraulic cylinders 251 arranged in parallel on the mounting frame 21. The telescopic end of the hammer lifting hydraulic cylinder 251 is provided with an inverted U-shaped mounting plate 252. The two ends of the inverted U-shaped mounting plate 252 are respectively connected with a cutting tool 253 and a crushing plate 254.

The transfer conveyor 38 transports the material to the vehicle-mounted crushing mechanism 4 for secondary crushing. After the opening and closing drive hydraulic cylinder 364 retracts the toggle frame 36 and closes it, the toggle drive motor 33 is started, so that the two toggle frames 36 move to the middle to carry out the next material transfer.
