[0002] Construction waste is one of the largest types of urban solid waste, accounting for about 30%-40% of the total urban waste. With the acceleration of urbanization, the amount of construction waste is also increasing. Effective treatment of construction waste can not only reduce the waste of land resources, but also reduce environmental pollution and realize the reuse of resources, which is of great significance to promoting green development and circular economy.

[0003] The first thing to solve in the treatment of construction waste is the crushing problem. Generally, a special crushing device is required to crush the construction waste. However, the construction waste crushing device used in the prior art has the following defects when used: 1. Often after crushing, garbage will still be of different sizes.

[0004] 2. Since construction waste is generally composed of materials such as concrete, a large amount of dust will appear during the crushing process. This dust will be blown out from the feed port, which will not only cause environmental pollution to the surrounding environment, but also cause certain harm to the health of the workers.

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0021] like Figure 1-Figure 6 As shown, a construction waste crushing device for construction engineering includes a crushing box 1, a feed port arranged at the top thereof, and a coarse screening box 22 integrally formed on the side of the crushing box 1 away from the feed port and connected thereto. Among them, a configuration component 3 is arranged on the side of the crushing box 1 close to the feed port to perform primary crushing of construction waste; at the same time, a screening component 2 is arranged in the coarse screening box 22 to screen the construction waste after primary crushing and perform secondary crushing on large pieces of waste, so as to improve the crushing efficiency and crushing quality, so that the construction waste can be fully crushed.

[0022] See attached Figure 1-Figure 2 as well as Figure 6 The configuration component 3 includes crushing rollers 36 that are connected to the inner walls of the crushing box 1 for primary crushing of construction waste and are rotatably connected to each other. At the same time, the two groups of crushing rollers 36 arranged opposite to each other are respectively fixedly installed with a rotating shaft 34 and a rotating shaft 4 35 on their axial center lines, and the two ends of the rotating shaft 34 and the rotating shaft 4 35 pass through the side wall of the crushing box 1, and the rotating shaft 34 and the rotating shaft 4 35 are rotatably connected to the side wall of the crushing box 1 by bearings, so that the two groups of crushing rollers 36 arranged opposite to each other can rotate relatively.

[0023] Furthermore, in order to drive the two groups of crushing rollers 36 to rotate in opposite directions, a motor 33 is fixedly installed on the outer wall of the crushing box 1, and the power output shaft of the motor 33 is connected to the rotating shaft 34 through a coupling. The rotating shaft 34 and the rotating shaft 4 35 are fixedly sleeved with two groups of meshing gears 2 37 at one end away from the motor 1 33. Therefore, when the motor 1 33 is started, the two matching gears 2 37 can be utilized to synchronously drive the crushing rollers 36 thereon in opposite directions to crush the garbage in the crushing box 1.

[0024] See attached Figure 2 as well as Figure 3 In this embodiment, the configuration component 3 also includes a dust removal bin 393 fixedly mounted on the outer wall of the crushing box 1 and connected to the interior thereof, a collection box 394 detachably connected to the bottom of the dust removal bin 393, and a negative pressure bin 395 fixedly mounted on the dust removal bin 393. The dust removal bin 393 is connected to the collection box 394 and the negative pressure bin 395, and a motor 2 398 is fixedly mounted in the negative pressure bin 395 by providing a support rod 397. At the same time, the power output shaft of the motor 2 398 is connected to the rotating shaft 5 399 through a coupling transmission, and then a fan blade 3991 is fixedly mounted on the rotating shaft 5 399, so that the motor 2 398 can be used to start the rotating shaft 5 398. 99 and the fan blade 3991 rotate synchronously, thereby generating negative pressure in the negative pressure bin 395. Since filter screens 396 are fixedly installed at both ends of the negative pressure bin 395, and the motor 2 398 is placed between the two sets of filter screens 396, the airflow passes through the filter screens 396, and suction is generated in the dust removal bin 393, thereby attracting the dust generated during the crushing process of the construction waste into the interior. After being filtered by the filter screen 396 located on the inner side, the dust in the crushing box 1 can be sucked into the collection box 394 for centralized collection, avoiding the dust from being blown out by the feed, which is beneficial to keeping the working environment clean and reducing the harm of dust to the health of the staff and the pollution to the surrounding environment.

[0025] Furthermore, in some other embodiments, a water supply pipe can be installed at the feed port of the crushing box 1, and mist nozzles can be installed in an array on the water supply pipe. During the process of crushing construction waste, mist water vapor can be sprayed at the feed port to prevent dust from being blown out, thereby improving the dust treatment effect.

[0026] Of course, in some other embodiments, the above-mentioned dust treatment related mechanisms may not be provided, and can be selected according to actual needs during specific application.

[0027] See attached Figure 2-Figure 6 The screening assembly 2 includes a filter plate 23 placed horizontally between the crushing box 1 and the coarse screening box 22 for receiving and screening the primary crushed material, and a crushing roller 29 connected to the inner wall of the coarse screening box 22 for secondary crushing of the screened construction waste.

[0028] Among them, one end of the filter plate 23 close to the feed port extends to the side wall of the crushing box 1 and is tangent thereto, and the other end extends obliquely downward to just above the bite of the two sets of crushing rollers 29, so that large pieces of garbage after primary crushing can directly fall between the crushing rollers 29 for secondary crushing. At the same time, both sides are attached to the side walls of the crushing box 1 and are tangent thereto, and the filter plate 23 extends from the feed end of the coarse screening box 22 to the inside thereof, and is slidably connected to the side wall of the coarse screening box 22, so that the construction waste after primary crushing can only flow along the filter plate 23 into the coarse screening box 22, or be screened and directly pass through the sieve mesh to fall to the bottom of the crushing box 1, ensuring that the construction waste can be fully screened and crushed.

[0029] In this embodiment, the filter plate 23 is rotatably connected to the crushing box 1 at one end near the feed port by a rotating rod 1 21, so that it can swing up and down relative to the crushing box 1. At the same time, a rotating rod 24 is rotatably connected to the crushing box 1, and a cam 25 is fixedly sleeved on the rotating rod 24, and the cam 25 is attached to the bottom surface of the filter plate 23. In this way, when the rotating rod 24 drives the cam 25 to rotate synchronously, the constantly changing diameter of the cam 25 can be used to push the filter plate 23 to swing up and down around the rotating rod 24, thereby realizing up and down cyclic vibration, so as to efficiently screen the primary crushed construction waste received on its upper surface, so as to improve the screening efficiency and crushing efficiency and avoid garbage accumulation and blockage on its surface.

[0030] Furthermore, in order to drive the filter plate 23 to swing up and down in a cycle, the rotating rod 24 and the rotating shaft 4 35 are fixedly sleeved with a pulley 38 at one end close to the motor 1 33, and a belt 1 39 is wound between the two sets of pulleys 1 38, and then when the motor 1 33 is started to drive the rotating shaft 4 35 to rotate, the pulley 1 38 and the two sets of pulleys 1 38 that cooperate with each other can be used to drive the rotating rod 24 to rotate synchronously, thereby driving the filter plate 23 to swing up and down in a cycle to screen the garbage.

[0031] Of course, in some other embodiments, spring shock absorbers can be installed between the four corners of the bottom surface of the filter plate 23 and the inner wall of the crushing box 1 and the coarse screening box 22, and a vibration motor can be installed on the bottom surface of the filter plate 23. The vibration motor can be used to drive the filter plate 23 to vibrate in a cycle to accelerate the screening of construction waste. During the production process, the required driving method can be selected according to different usage scenarios.

[0032] Again refer to the attached Figure 2-Figure 6Among them, two groups of crushing rollers 29 arranged opposite to each other are respectively fixedly installed with a rotating shaft 27 and a rotating shaft 28 on their axis lines, and both ends of the rotating shaft 27 and the rotating shaft 28 penetrate the side wall of the coarse screening box 22 and are rotatably connected thereto by bearings, and the rotating shaft 27 and the rotating shaft 28 are fixedly sleeved with two groups of meshing gears 291 at one end close to the motor 33, so that the two groups of gears 291 cooperate with each other so that the two groups of crushing rollers 29 can rotate synchronously relative to each other to perform secondary crushing of large pieces of garbage.

[0033] In this embodiment, in order to drive the two groups of crushing rollers 29 to rotate relative to each other, a pulley 391 is fixedly installed on the end of the rotating shaft 27 away from the motor 33 and the end of the rotating rod 24, and a belt 392 is wound between the two groups of pulleys 391. In this way, when the motor 33 drives the rotating rod 24 to rotate synchronously, the rotating shaft 27 can be driven to rotate synchronously. The two groups of gears 291 cooperate with each other to enable the two groups of crushing rollers 29 to rotate synchronously to achieve secondary crushing of large pieces of garbage. There is no need to screen and crush the construction waste multiple times, thereby reducing the cumbersome steps of garbage disposal and improving the efficiency of garbage crushing and screening.

[0034] Of course, in some other embodiments, the motor three can be installed on the outer wall of the coarse screening box 22 and its power output shaft can be connected to the rotating shaft one 27 through a coupling to synchronously drive the rotating shaft one 27 and the rotating shaft two 28 to rotate relative to each other, so as to perform secondary crushing on large pieces of garbage.

[0035] See attached Figure 1-Figure 2 A mounting groove 31 is provided at the bottom of the crushing box 1, and a collecting box 32 is slidably installed in the mounting groove 31. In contrast, a discharge port 26 inclined toward the collecting box 32 is provided in the coarse screening box 22, so that the construction waste screened by the filter plate 23 and crushed by the crushing roller 29 can be stored in the collecting box 32 for unified recycling.

[0036] Of course, in some other examples, the crushing box 1 can be raised by using a high-leg bracket, and a general discharge port can be opened at the bottom of the crushing box 1. The garbage transfer cart or conveyor belt and other devices can be placed directly under the general discharge port, so that the construction waste can be directly transferred after the crushing is completed, which is convenient and quick.

[0037] The specific working principle of this embodiment is: when in use, first, the garbage to be crushed can be put into the crushing box 1 from the feeding port of the crushing box 1, and then, the motor 1 33 is started. The motor 1 33 will cooperate with the two gears 2 37, so that the rotating shaft 34 and the rotating shaft 4 35 can drive the crushing rollers 36 thereon in relative directions to crush the garbage in the crushing box 1.

[0038] Secondly, the garbage crushed by the crushing roller 36 will fall onto the filter plate 23. At the same time, the rotating shaft 4 35, with the cooperation of the two pulleys 1 38 and the belt 1 39, enables the rotating rod 24 to drive the cam 25 thereon to rotate synchronously with the rotating shaft 4 35. When the cam 25 rotates, the filter plate 23 will vibrate up and down in cooperation with the rotating rod 1 21. In this way, large pieces of garbage can roll through the slope of the filter plate 23 into the coarse screening box 22, and small pieces of garbage can flow into the collection box 32 through the filter holes of the filter plate 23 for collection.

[0039] Finally, when large pieces of garbage roll into the coarse screening box 22, the rotating shaft 27 in the coarse screening box 22 will use the rotating rod 24 to make the rotating shaft 27 and the rotating rod 24 rotate synchronously with each other under the cooperation of the two pulleys 2 391 and the belt 2 392. At the same time, when the rotating shaft 27 rotates, with the cooperation of the two gears 1 291, the rotating shaft 27 and the rotating shaft 2 28 can respectively drive the crushing roller 1 29 thereon to move relative to each other, so as to further crush the large pieces of garbage in the coarse screening box 22. The crushed garbage can flow into the collection box 32 through the discharge port 26 for centralized collection, thereby reducing the cumbersome steps of garbage disposal and improving the efficiency of garbage crushing and screening.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
