[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a construction waste crushing and iron removal device, comprising a crushing box 1, a material guide frame 3 is fixedly connected to the inner top of the crushing box 1, a stepper motor 4 is fixedly connected to the right side of the crushing box 1, the output end of the stepper motor 4 penetrates the crushing box 1 and is fixedly connected to the first crushing roller 5, a bidirectional screw rod 6 is rotatably connected to the left side of the middle and upper part of the rear end of the crushing box 1, the front end of the bidirectional screw rod 6 penetrates the crushing box 1 and is rotatably connected to the inner front side of the crushing box 1, the front and rear sides of the outer wall of the bidirectional screw rod 6 are both threadedly connected with a movable plate 7, a U-shaped frame 8 is fixedly connected to the right side of the movable plate 7, a servo motor 9 is fixedly connected to the right side of the U-shaped frame 8, the output end of the servo motor 9 penetrates the U-shaped frame 8 and is fixedly connected to the second crushing roller 10, a sorting mechanism 2 is arranged at the middle and lower part of the inner side of the crushing box 1, a feed port 14 is connected to the middle part of the top of the crushing box 1, a plurality of fixed rods 11 are fixedly connected to the left end of the middle and upper part of the inner side of the crushing box 1, and the left and right sides of the two movable plates 7 are respectively slidably connected to the outer sides of the corresponding fixed rods 11;

[0038] Specifically, by rotating the bidirectional screw rod 6, the movable plate 7 can be moved toward the middle from the outside of the fixed rod 11, thereby driving the U-shaped frame 8 to move. This design allows us to adjust the distance between the first crushing roller 5 and the second crushing roller 10 as needed to obtain construction waste of different sizes. In addition, through the left observation window 15, the operator can observe the distance between the first crushing roller 5 and the second crushing roller 10 in real time, so as to accurately adjust the size of the waste. At the same time, the observation window 15 can also monitor the operating status of the device in real time. Once a large piece of iron object is found to enter between the first crushing roller 5 and the second crushing roller 10, measures can be taken immediately to perform iron protection to avoid damage to the device. This iron protection function not only improves the service life of the device, but also further improves its work efficiency.

[0039] Reference Figure 2 and Figure 3 The sorting mechanism 2 includes a servo motor 201 and a transmission belt 204. The servo motor 201 is fixedly connected to the left side of the lower middle part of the rear end of the crushing box 1. The output end of the servo motor 201 passes through the crushing box 1 and is fixedly connected to the active roller 202. The right side of the crushing box 1 is rotatably connected to the driven roller 203. The driven roller 203 is connected to the active roller 202 through the transmission belt 204. The inner side of the transmission belt 204 is fixedly connected to the soft magnetic plate 205. The lower middle part of the inner right end of the crushing box 1 A scraper 206 is fixedly connected, and a collection box 207 is provided at the left and right ends of the lower middle part of the front side of the crushing box 1. The rear side of the collection box 207 penetrates the crushing box 1. Slide blocks 208 are fixedly connected to the left and right sides of the bottom of the two collection boxes 207. A plurality of slide grooves 209 are provided at the inner bottom of the crushing box 1. The slide blocks 208 are slidably connected to the corresponding slide grooves 209 respectively. A handle 210 is fixedly connected to the front side of the collection box 207. The transmission belt 204 and the soft magnetic plate 205 are both inclined.

[0040] Specifically, the crushed construction waste will fall onto the transmission belt 204, and the metal waste in the construction waste will be firmly adsorbed by the soft magnetic plate 205 under the action of magnetic force, while the non-metallic waste will fall directly onto the transmission belt 204. At this time, the servo motor 201 starts to work, which drives the active roller 202 to rotate, and the driven roller 203 also rotates accordingly. This linkage mechanism enables the transmission belt 204 to start operating, and the non-metallic waste will fall into the left collection box 207 driven by the transmission belt 204, while the metal waste adsorbed by the soft magnetic plate 205 will be gradually scraped off by the scraper 206 and fall into the right collection box 207 during the continuous operation of the transmission belt 204. After the crushing work is completed, pull the handle 210, and the two collection boxes 207 can be easily pulled out. At this time, the metal waste and non-metallic waste are respectively concentrated in the two collection boxes 207, which provides great convenience for the subsequent centralized processing work.

[0041] Reference Figure 1 and Figure 2 A switch 12 is fixedly connected to the lower middle part of the right side of the crushing box 1. The switch 12 is electrically connected to the servo motor 201, the stepper motor 4 and the servo motor 9 respectively. A protective cover 13 is arranged on the outer side of the switch 12. The top of the protective cover 13 is rotatably connected to the right side of the crushing box 1 through a rotating shaft.

[0042] Specifically, the operation of the servo motor 201 , the stepper motor 4 and the servo motor 9 can be controlled by the switch 12 , and the protective cover 13 can protect the switch 12 from being damaged by external factors.

[0043] Reference Figure 1 and Figure 3 Observation windows 15 are provided in the middle of the front side and the upper middle of the left side of the crushing box 1;

[0044] Specifically, the internal conditions of the crushing box 1 can be observed at any time through the observation window 15, and timely responses can be made when encountering special situations.

[0045] Working principle: When using the device, the construction waste to be crushed can be poured into the crushing box 1 through the feed port 14. At this time, the construction waste to be crushed will slide between the first crushing roller 5 and the second crushing roller 10 through the material guide frame 3. Then, the stepper motor 4 and the servo motor 9 are started. The stepper motor 4 can drive the first crushing roller 5 to rotate, and the servo motor 9 can drive the second crushing roller 10 to rotate, so that the fallen construction waste raw materials can be crushed. When it is necessary to obtain construction waste of different sizes, the bidirectional screw rod 6 is rotated at this time, and the movable plate 7 on the bidirectional screw rod 6 will move toward the middle on the outside of the fixed rod 11, and the U-shaped frame 8 will move accordingly. The spacing between the first crushing roller 5 and the second crushing roller 10 can be adjusted by observing the observation window 15 on the left, so that the required size of construction waste can be obtained, thereby improving the practicality of the device. At the same time, the device can be protected from iron through the left observation window 15. Thereby, the service life of the device can be improved, and the crushed construction waste will fall onto the transmission belt 204, the metal waste in the construction waste will be adsorbed by the soft magnetic plate 205, and the non-metal waste will directly fall onto the transmission belt 204. At this time, the servo motor 201 can drive the active roller 202 to rotate, and the driven roller 203 will rotate accordingly, so that the transmission belt 204 can start to operate. At this time, the non-metal waste will fall into the left collection box 207, and the scraper 206 can scrape off the metal waste adsorbed on the transmission belt 204, and the scraped metal waste will fall into the right collection box 207. After the crushing work is completed, the two collection boxes 207 can be pulled out by the handle 210 to centrally process the collected metal waste and non-metal waste, so that the metal waste and non-metal waste in the crushed construction waste can be separated, and the staff does not need to manually perform the separation work, thereby reducing the workload of the staff.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
