Description
Technical Field
[0001] The utility model relates to the technical field of construction waste recycling, in particular to a construction waste crushing device for building construction. Background Art
[0002] With the continuous acceleration of urbanization, the amount of construction waste generated and discharged in cities is also growing rapidly. These construction wastes not only occupy a certain space, but also cause waste of resources. Construction waste crushers can turn construction waste into treasure.
[0003] Traditional crushing devices generally only crush construction waste once, and the sizes of the crushed particles are different. Screening equipment is needed to screen the crushed construction waste again to obtain finer particles, which makes it impossible to complete the recycling in one go. In addition, larger-sized construction waste is collected and put into the crushing equipment again, which undoubtedly increases the operation steps and difficulty. Based on this, a construction waste crushing device for construction is proposed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a construction waste crushing device for construction, which effectively solves the shortcomings of the prior art.
[0005] In order to achieve the above-mentioned objectives, an embodiment of the utility model on one side provides a construction waste crushing device for construction, comprising a closed shell, a crushing box is fixedly connected to one side of the top surface of the closed shell, two crushing rollers are arranged inside the closed shell, a first discharge port is arranged at the bottom end of the closed shell, four support seats are fixedly connected to the two inner walls of the closed shell, springs are arranged at the tops of the four support seats, and inclined screen plates are arranged at the tops of the four springs, a first vibration motor is fixedly connected to both sides of the bottom surface of the screen plate, a collecting hopper is arranged at one end of the sieve plate, one end of which protrudes from the closed shell, a tilted support frame is arranged on one side of the closed shell, a conveyor belt is rotatably connected inside the closed shell, the top of the conveyor belt extends to just above the crushing box, a guide groove is arranged at one end of the collecting hopper, a second vibration motor is fixedly connected to the bottom surface of the guide groove, and one end of the guide groove is tilted downward and extends to the bottom end of the conveyor belt.
[0006] Preferably, any of the above schemes has an opening on one side of the closing shell close to the guide groove, and a closing belt is arranged inside the closing shell, and the closing belt is fixedly connected to the outer wall of the collecting hopper. The closing belt in this scheme blocks the opening between the collecting hopper and the closing shell, and the closing belt can be made of rubber material, so as to avoid affecting the vibration of the collecting hopper through the deformation of the closing belt itself.
[0007] Preferably, any of the above schemes has three sides of the sieve plate bent upwards, leaving a gap between the sieve plate and the inner wall of the closed shell. This scheme facilitates blocking the crushed construction waste and prevents it from falling to the bottom of the closed shell. At the same time, the remaining gap provides a larger swing margin for the sieve plate to avoid contact between the sieve plate and the inner wall of the closed shell.
[0008] Preferably, any of the above schemes is that the shape of the collecting hopper is a hollow cone, one end of the collecting hopper enters into the interior of the guide trough and leaves a gap between the end and the inner wall of the guide trough. By using this scheme, the guide trough is opened on one side close to the collecting hopper, and the thinner end of the collecting hopper enters into the interior of the guide trough, which facilitates the entry of larger-sized construction waste into the interior of the guide trough.
[0009] Preferably, any of the above schemes is that a limit hopper is provided at the bottom end of the support frame, with a gap left between it and the bottom end of the guide trough. The limit hopper in this scheme facilitates the diversion of construction waste flowing out of the guide trough to prevent the waste from scattering, and further facilitates the operation of the conveyor belt to return larger-sized construction waste to the inside of the crushing box for further crushing.

At the same time, the construction waste with larger size enters the conveyor belt along the collecting hopper and the guide trough, and is sent back to the crushing box through the conveyor belt, so as to facilitate the recycling of construction waste to meet the use requirements. The overall structure is simple and the design is reasonable, which reduces the overall operation difficulty and is easy to operate and use.
[0012] 2. The construction waste crushing device for building construction is provided with a screen plate, and the three sides of the screen plate are bent and tilted upward, so as to block the crushed construction waste and prevent the construction waste from falling to the bottom of the closed shell, thereby ensuring the stability and sustainability of the screening.

[0024] The closing shell 1 is opened on one side close to the guide groove 5, and a closing belt 10 is arranged inside the closing shell 1. The closing belt 10 is fixedly connected to the outer wall of the collecting hopper 8. As an optional technical solution of the utility model, the closing belt 10 blocks the opening between the collecting hopper 8 and the closing shell 1. At the same time, the closing belt 10 can be made of rubber material, and then the deformation of the closing belt 10 itself can avoid affecting the vibration of the collecting hopper 8.
[0025] The three sides of the sieve plate 14 are bent upward, and a gap is left between them and the inner wall of the closed shell 1.

[0032] 4) Smaller-sized construction waste passes through the screen plate 14 and flows out from the first discharge port 9, while larger-sized construction waste flows along the collecting hopper 8 and the guide trough 5 into the conveyor belt 4;
[0033] 5) The conveyor belt 4 is driven by an external drive motor to send the larger-sized construction waste back to the crushing box 2 for recycling and crushing.
[0034] In summary, when the user uses it, by setting the closed shell 1 and the crushing box 2, the crushing box 2 is provided with two crushing rollers 11, and the closed shell 1 is provided with an inclined screen plate 14. By putting construction waste into the crushing box 2, the two crushing rollers 11 crush the construction waste once, and at the same time, the two first vibration motors 13 are powered on to generate an exciting force, which drives the screen plate 14 to vibrate, so as to screen the crushed construction waste. At the same time, the construction waste with larger size enters the conveyor belt 4 along the collecting hopper 8 and the guide trough 5, and is sent back to the crushing box 2 through the conveyor belt 4, so as to facilitate the recycling of the construction waste to achieve The requirements of use are met, the overall structure is simple, the design is reasonable, the overall operating difficulty is reduced, and it is easy to operate and use. A sieve plate 14 is set, and the three sides of the sieve plate 14 are bent and tilted upward, so as to block the crushed construction waste and prevent the construction waste from falling to the bottom of the closed shell 1, thereby ensuring the stability and sustainability of the screening. Finally, a guide groove 5 is set, which is tilted, and the bottom surface of the guide groove 5 is fixedly connected to a second vibration motor 7. The second vibration motor 7 is powered on to vibrate larger construction waste and make the construction waste quickly slide to the top surface of the conveyor belt 4, thereby facilitating the crushing of a large amount of construction waste.
