[0023] As described in the background section, the process of using the aforementioned crusher to process construction waste generates a large amount of smoke and dust, which in turn pollutes the surrounding environment and harms the health of workers.

[0024] To solve this technical problem, this utility model provides a construction waste shredder, which is applied to construction projects;

[0025] The system includes a casing 1, a crushing roller assembly 2 inside the casing 1, a top cover 3 fixed to the top of the casing 1, an inlet 4 inside the top cover 3, a water tank 5 inside the casing 1 above the crushing roller assembly 2, a water pump 6 mounted on the top of the top cover 3, a straight water guide pipe 7 rotatably connected inside the casing 1 at the center of the bottom of the top cover 3, multiple nozzles 8 connected to the outside of the straight water guide pipe 7 inside the casing 1, a water pump 9 fixedly connected to the water pump 6, the end of the water pump 9 away from the water pump 6 extending to the inside of the water tank 5, and a water outlet pipe 10 fixedly connected to the water pump 6, the end of the water outlet pipe 10 away from the water pump 6 penetrating the casing 1 and extending to the inside of the straight water guide pipe 7, and the water outlet pipe 10 rotatably connected to the straight water guide pipe 7.

[0026] The construction waste crusher provided by this utility model, through its overall structural design, enables dust suppression treatment of the smoke and dust generated during the crushing process of construction waste through the crushing roller group 2 inside the machine box 1, effectively reducing the pollution of the environment by the smoke and dust.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1:

[0030] Please refer to Figure 1-3 A construction waste crusher includes a casing 1, a crushing roller assembly 2 is provided inside the casing 1, and a top cover 3 is fixed at the top of the casing 1. In order to facilitate the feeding of construction waste into the casing 1 and crushing it through the crushing roller assembly 2, an inlet 4 is provided inside the top cover 3.

[0031] In order to reduce the dust generated during the crushing process and effectively reduce the pollution of the environment, a water tank 5 is placed inside the machine box 1 and above the crushing roller group 2. A water pump 6 is installed at the top of the top cover 3. A straight water guide pipe 7 is rotatably connected inside the machine box 1 and at the center of the bottom of the top cover 3. Multiple nozzles 8 are connected to the outside of the straight water guide pipe 7 and inside the machine box 1.

[0032] In order to facilitate the pumping of water from the water tank 5 to the straight water pipe 7, and then to spray it out through the nozzle 8 to achieve dust suppression, the water pump 6 is fixedly connected to the water inlet with a water pipe 9. The end of the water pipe 9 away from the water pump 6 extends to the inside of the water tank 5. The water pump 6 is fixedly connected to the water outlet with a water outlet pipe 10. The end of the water outlet pipe 10 away from the water pump 6 passes through the casing 1 and extends to the inside of the straight water pipe 7. The water outlet pipe 10 is rotatably connected to the straight water pipe 7.

[0033] In order to facilitate the replenishment of water into the water tank 5 at any time, a water replenishment pipe seat 11 is fixedly connected to the outer side of the upper end of the water tank 5. In order to facilitate the flexible adjustment of the spray angle of the nozzle 8 to achieve precise dust suppression, a first flat gear 12 is fixed on the outer side of the water guide straight pipe 7 and located on the outer side of the machine box 1. A reduction motor 13 is fixed on the outer side of the machine box 1 and located on the outer side of the first flat gear 12. A second flat gear 14 is fixed at the output end of the reduction motor 13. The second flat gear 14 is meshed with the first flat gear 12.

[0034] Example 2:

[0035] The construction waste shredder provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, wastewater is generated during the dust suppression process, and the wastewater falls downwards with the construction waste. In order to filter and separate the crushed construction waste and wastewater, so as to facilitate the recycling of the waste and wastewater separately, a base plate 15 is fixed at the lower end of the casing 1. The casing 1 and the base plate 15 are connected. A base frame 16 is fixed at the lower end of the base plate 15. A hollow support 17 is fixed at the center of the inner side of the base frame 16. Both ends of the hollow support 17 are fixed with water filter guide plates 18. The two water filter guide plates 18 facilitate the flow of construction waste while filtering and separating wastewater.

[0036] In order to collect garbage and wastewater separately, drainage grooves 20 are provided inside the base frame 16 and at the lower end of the two filter guide plates 18. Garbage collection platforms 21 are fixed at both ends of the base frame 16. Wastewater receiving seats 22 are slidably connected between the two garbage collection platforms 21. In order to ensure that the filter guide plates 18 can smoothly guide garbage and separate wastewater, a vibration motor 19 is installed inside the hollow support 17.

[0037] In order to facilitate the positioning of the wastewater receiving seat 22 and prevent the wastewater receiving seat 22 from detaching from the two garbage collection platforms 21 without human intervention, support shafts 23 are fixed on both sides of the base frame 16. Limiting plates 24 are rotatably connected to the outer sides of the two support shafts 23. The lower ends of the two limiting plates 24 are located on both sides of the wastewater receiving seat 22 and are in contact with the wastewater receiving seat 22.

[0038] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0039] The construction waste crusher provided by this utility model is used as follows: Before crushing the waste, the water pump 6 is started to draw water out of the water tank 5 through the water pipe 9, and the water is discharged into the straight water pipe 7 through the water outlet pipe 10, so that it can be sprayed out through the nozzle 8 to achieve dust suppression. The reduction motor 13 is started to drive the second flat gear 14 to rotate. The meshing of the second flat gear 14 with the first flat gear 12 drives the straight water pipe 7 to rotate, so that the spray angle of the nozzle 8 can be adjusted to ensure accurate dust suppression.

[0040] At this time, the construction waste is fed into the machine box 1 through the feed port 4, and after being crushed by the crushing roller group 2, it falls downward. At the same time, the wastewater generated by dust suppression falls downward along with the waste. The two water filter guide plates 18 facilitate the flow of construction waste, which rolls into the inside of the waste collection platform 21 for collection. Meanwhile, the wastewater is filtered and separated, and after passing through the water filter guide plates 18, the wastewater drips into the wastewater receiving seat 22 through the drainage trough 20 for collection. This achieves the separate collection of waste and wastewater, which facilitates subsequent recycling.

[0041] During the process of the filter guide plate 18 guiding the garbage and filtering and separating the wastewater, the vibration motor 19 is started to drive the filter guide plate 18 to vibrate, thereby ensuring that the filter guide plate 18 can smoothly realize the guiding and filtering functions. After the limiting plate 24 is rotated so that it is no longer attached to the wastewater receiving seat 22, the limitation on the wastewater receiving seat 22 is released, making it easy to slide out the wastewater receiving seat 22 for wastewater recycling.
