[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-3This utility model provides an embodiment of a waste crushing device for construction projects, comprising a crushing box 1, a motor 4 fixedly connected to the front end of the crushing box 1, a drive shaft 5 fixedly connected to the drive end of the motor 4, a main gear 6 fixedly connected to the outer wall of the drive shaft 5, a driven gear 7 meshing with the outer wall of the main gear 6, a driven shaft 8 fixedly connected to the inner wall of the driven gear 7, both the drive shaft 5 and the driven shaft 8 being rotatably connected to the inner wall of the crushing box 1, and multiple crushing teeth 9 fixedly connected to the outer walls of both the drive shaft 5 and the driven shaft 8. Baffles 10 are provided on both the left and right sides above the crushing tooth 9. The top of the opposite side of the baffles 10 is inclined. A sliding rod 11 is fixedly connected to the opposite end of the baffles 10. The outer wall of the sliding rod 11 is slidably connected to the inner wall of the crushing box 1. A handle 12 is fixedly connected to the opposite end of the sliding rod 11. A spring 13 is sleeved on the outer wall of the sliding rod 11. One end of the spring 13 is connected to the baffle 10, and the other end of the spring 13 is connected to the inner wall of the crushing box 1. A feed pipe 2 is fixedly connected to the top of the crushing box 1, and a discharge pipe 3 is fixedly connected to the bottom of the crushing box 1.
[0025] Specifically, a controller is installed on the outer wall of the crushing box 1. The controller controls the motor 4 and the fan 17 through an electrical connection. When construction waste falls onto the baffle 10 and squeezes the baffle 10, it moves to both sides, causing the construction waste on the baffle 10 to fall onto the crushing teeth 9 below. When there is too little construction waste to squeeze the baffle 10, and the construction waste stays on the baffle 10, the handles 12 on both sides of the crushing box 1 can be pulled, causing the handles 12 to drive the baffle 10 to move to both sides through the slide rod 11, causing the construction waste to fall.
[0026] Reference Figure 4 and Figure 5 The rear end of the crushing box 1 is fixedly connected to a connecting pipe 14. Multiple fans 17 are fixedly connected to the inner wall of the connecting pipe 14. A filter plate 18 is provided at the front end of the fan 17. The outer wall of the filter plate 18 is fixedly connected to the inner wall of the connecting pipe 14. A drawer 16 is slidably installed on the inner wall of the dust collection box 15. A handle is fixedly connected to the rear end of the drawer 16. The dust collection box 15 is fixedly connected to the rear end of the connecting pipe 14.
[0027] Specifically, when the fan 17 sucks the dust generated during the crushing process into the dust collection box 15, the filter plate 18 fixed inside the connecting pipe 14 can prevent the crushed aggregate from being sucked into the dust collection box 15 together. The top of the dust collection box 15 is provided with an air hole for the fan 17 to exhaust air. The handle fixed on the drawer 16 makes it easy to take the drawer 16 out of the dust collection box 15.
[0028] Working principle: In use, first start the motor 4 and fan 17, then add construction waste into the crushing box 1 through the feed pipe 2. The construction waste will fall onto the baffle 10, causing the baffle 10 to be squeezed to both sides and moved away. The construction waste falls onto the crushing teeth 9 below. The baffle 10 will drive the slide rod 11 to move outward of the crushing box 1, while compressing the spring 13. When the construction waste falls to the bottom, the spring 13 will rebound the baffle 10 above the crushing teeth 9 to prevent the waste from splashing out and accidentally injuring the workers during the crushing process. When the waste falls onto the crushing teeth 9, the motor 4 drives the drive shaft 5 to rotate, which in turn drives the main gear 6 to rotate, thereby driving the driven gear 7 to rotate. The driven gear 7 drives the driven shaft 8 to rotate. The drive shaft 5 and the driven shaft 8 drive the multiple crushing teeth 9 on the outer wall to crush the construction waste. A large amount of dust will be generated during crushing. At this time, the fan 17 will suck the generated dust into the dust collection box 15 through the connecting pipe 14. Later, you only need to open the drawer 16 to clean the collected dust.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
