[0004] The above-mentioned method and equipment for preparing environmentally friendly concrete using construction solid waste, uses a first gear roller and a second gear roller to crush the squeezed construction debris, but the first gear roller and the second gear roller are not convenient to disassemble and replace, making it difficult to crush the construction debris according to different size requirements, resulting in a problem of reduced applicability of the equipment. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the existing method and equipment for preparing environmentally friendly concrete using construction solid waste. The squeezed construction waste is crushed by a first gear roller and a second gear roller. However, the first gear roller and the second gear roller are not convenient to disassemble and replace, making it difficult to crush the construction waste to different sizes, which reduces the applicability of the equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A preparation device for environmentally friendly concrete using construction solid waste comprises a crushing box, two crushing rollers installed in the crushing box for crushing concrete, and a disassembly assembly for disassembling and replacing the specifications of the crushing rollers, wherein the disassembly assembly comprises a fixing plate fixedly connected to a side wall of one side of the crushing box, two first motors are arranged on the upper surface of the fixing plate, two rotating shafts are arranged on the side walls on both sides of the crushing box, opposite ends of the rotating shafts penetrate the crushing box and are fixedly connected to square plug rods, square slots are arranged at both ends of the crushing rollers, and the square plug rods are plugged into the square slots, wherein the ends of the two rotating shafts away from the crushing rollers are respectively fixedly connected to the output ends of the first motor, and the ends of the other two rotating shafts away from the crushing rollers are rotatably connected to fixing blocks, a plurality of first fixing bolts are arranged on the fixing block, the first fixing bolts all penetrate the fixing block and are threadedly connected to the crushing box, a plurality of second fixing bolts are arranged on the first motor, the second fixing bolts all penetrate the first motor and are threadedly connected to the fixing plate.

[0008] By adopting the above technical scheme, when in use, pour the construction debris from the top of the crushing box, and start the two first motors to make the crushing rollers rotate forward and backward to crush the construction debris. When the crushing size of the construction debris needs to be changed, the first fixing bolt and the second fixing bolt are removed so that the fixing block and the first motor can be moved, and the square plug rod is pulled out of the square slot to remove the crushing roller from the crushing box, and then crushing rollers of different specifications are installed for crushing, thereby avoiding as much as possible the problem of difficulty in crushing construction debris of different sizes, which reduces the applicability of the equipment.

[0009] Optionally, the bottom end of the crushing box is fixedly connected to a communicating pipe, the bottom end of the pipe is fixedly connected to a material receiving box, the bottom end of the material receiving box is fixedly connected to a discharge pipe, and a solenoid valve is installed on the discharge pipe.

[0010] By adopting the above technical solution, the crushed construction debris can be transported to the receiving box for collection through the pipeline, and the construction debris in the receiving box can be discharged from the discharge pipe by starting the solenoid valve, which is convenient for use.

[0011] Optionally, the inner bottom ends of the crushing box and the material receiving box are both configured to be funnel-shaped.

[0012] By adopting the above technical solution, the funnel-shaped crushing box and the collecting box can prevent construction debris from remaining in the crushing box or the collecting box and being difficult to discharge.

A second motor is provided in the operating box, and an output end of the second motor passes through the bottom end of the operating box and is fixedly connected to a dredging shaft, and one end of the dredging shaft away from the second motor passes through the pipeline and the material receiving box and is located inside the discharge pipe.

[0014] By adopting the above technical solution, the second motor is started to rotate the dredging shaft in the pipeline and the discharge pipe, so that the pipeline and the discharge pipe can be dredged to prevent construction debris from clogging the pipeline or the discharge pipe.

[0015] Optionally, the top end of the operation box is arranged to be inclined.

[0016] By adopting the above technical solution, it is possible to prevent the crushed construction debris from falling and accumulating on top of the operating box, making it difficult to remove.

[0017] Optionally, a feed hopper is fixedly connected to the top of the crushing box, and a metal adsorption plate is fixedly connected to one side of the inner wall of the feed hopper.

[0018] By adopting the above technical solution, the construction debris can be conveniently poured into the crushing box through the feed hopper.

[0020] By adopting the above technical solution, it is possible to prevent the square rod from partially extending out of the two ends of the crushing roller when inserted into the square slot, causing the square rod to be embedded in the inner wall of the crushing box. The gap between the square rod and the crushing box may cause construction debris to be stuck and filled, making it difficult for the crushing roller to rotate.

[0021] In summary, the beneficial effects of this application are as follows:

Two rotating shafts 5 for driving the crushing rollers 2 to rotate are arranged on both side walls of the crushing box 1. The opposite ends of the rotating shafts 5 penetrate the crushing box 1 and are fixedly connected with square plug rods 6 for detachable connection with the crushing rollers 2. Square slots 7 are provided at both ends of the crushing roller 2, and square plug rods 6 are plugged into the square slots 7. The ends of the two rotating shafts 5 away from the crushing roller 2 are fixedly connected to the output ends of the first motor 4 respectively, and the other two rotating shafts 5 are rotatably connected to the fixed blocks 8 at the ends away from the crushing roller 2. The fixed blocks 8 are provided with a plurality of first fixing bolts 9 for fixing the fixed blocks 8.
