Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete crushing device. Background Art

[0002] At present, a large amount of construction waste will be generated during the demolition of buildings, most of which is waste concrete. If not properly handled, these waste concrete will pollute the environment, have adverse effects on the soil, and may even pose a threat to the personal safety of residents. In order to solve this problem, the current recycling method is to crush the waste concrete and replace traditional minerals as recycled aggregates. This method can reduce the exploitation of natural resources, reduce environmental damage, and improve the utilization efficiency of resources. By crushing the waste concrete, it can be converted into smaller particles, which can be used to make new concrete or other building materials. This recycled aggregate can not only replace traditional minerals, but also has higher strength and durability, and can meet the structural and safety requirements of buildings.

[0003] The authorization announcement number in the prior art is: CN213000311U, and the name is: a concrete crushing device, including a crushing drum, a feed pipe, a discharge port, a crushing assembly, etc. The crushing assembly includes a crushing motor, a crushing roller and a crushing blade. The crushing motor drives the crushing roller to rotate, and the crushing blades are staggered and fixed on the outer wall of the crushing roller. When the concrete enters the crushing drum, it is squeezed by the crushing roller and impacted by the crushing blades, and is crushed into small particles and discharged from the discharge port. This patent can improve the production efficiency of the enterprise and ensure that the crushed particle size of the concrete meets the use requirements.

[0004] However, this patent uses a fan-shaped screening plate to screen the crushed material, and the crushed material itself has an irregular shape, which makes the crushed material easy to be blocked above the screening plate and difficult to clean.

[0028] like Figure 1 to Figure 5 As shown, this embodiment proposes a concrete crushing device, including a base 1, a box body 9 is fixedly connected to the inside of the base 1 by bolts, a first motor 2 is installed on one side of the box body 9, two crushing wheels 7 are rotatably installed inside the box body 9, a first motor 2 is installed on the top of the base 1, an output end of the first motor 2 is fixedly connected to a coaxially arranged rotating shaft 15 through a coupling, one end of the rotating shaft 15 is fixedly connected to one end of one of the crushing wheels 7, a driving wheel 14 is fixedly sleeved on the rotating shaft 15, a driven wheel 17 is rotatably installed inside the box body 9, a synchronous belt 16 is jointly sleeved on the driving wheel 14 and the driven wheel 17, a second telescopic rod 18 is welded on one side of the driven wheel 17, and a first motor 2 is installed on one side of the box body 9. A second motor 10 is installed, and the output end of the second motor 10 is fixedly connected to a coaxially arranged round rod through a coupling, a rocker 12 is welded to one end of the round rod, and a first telescopic rod 13 is movably hinged to one end of the rocker 12. A slider 22 is fixedly connected to one side of the first telescopic rod 13 by a screw, and the slider 22 is slidably connected to the inside of the box body 9. Through the arrangement of the first motor 2 and the screen 19 and other structures, the material is put into the hopper, and then the first motor 2 is turned on, so that the output end of the first motor crushes the waste material, and the second telescopic rod 18 also rotates to form a knocking vibration on the bottom wall, so that the crushed material is not easy to be blocked, and the second motor 10 drives the screen 19 for screening to achieve a better screening effect.

[0029] like Figure 2 As shown, a first discharge port 8 is disposed on one side of the box body 9 , and a second discharge port 11 is disposed on the other side of the box body 9 . The first discharge port 8 is located below the second discharge port 11 .

[0030] like Figure 2-3 As shown, a screen 19 is slidably mounted inside the box 9 , and the bottom of the first telescopic rod 13 is fixedly connected to the top of the screen 19 .

[0031] like Figure 2 As shown, an inclined groove is provided inside the box body 9, and both ends of the screen 19 are slidably connected inside the inclined groove, and the screen 19 is inclined.

[0032] like Figure 2 to Figure 5 As shown, a slide groove 23 is provided inside the box body 9 , and the slider 22 is slidably connected inside the slide groove 23 .

[0033] like Figure 3 As shown, the interior of the box body 9 is a hollow structure, the bottom wall of the box body 9 is inclined, and one end of the second telescopic rod 18 is in contact with the bottom wall of the box body 9.

[0034] like Figure 1 to Figure 5 As shown, one end of the two crushing wheels 7 is respectively fixedly sleeved with a first gear 20 and a second gear 21, and the first gear 20 and the second gear 21 are meshed and connected.

[0035] In this embodiment, the concrete block to be crushed is placed in the hopper 3, and then the power of the first motor 2 and the second motor 10 is turned on. The output end of the first motor 2 drives the shaft 15 to rotate through the coupling, and the shaft 15 drives the first gear 20 to rotate, and the second gear 21 also rotates accordingly, so that the two crushing wheels 7 rotate to crush the concrete block. The crushed material first falls on the screen 19, and the output end of the second motor 10 drives the rocker 12 to rotate through the coupling, and the rocker 12 drives the first telescopic rod to move, so that the screen 19 moves. One side of the material port 11 is inclined, so that when the screen 19 is swinging for screening, small particles will fall directly from the screen 19 and fall from the first discharge port 8, and large particles will fall to the other side due to the inclined screen 19, and then slide from the second discharge port 11, making it easier to distinguish. When the rotating shaft 15 rotates, the driving wheel 14 will drive the driven wheel 17 to rotate through the synchronous belt 16, and the driven wheel 17 will drive the second telescopic rod 18 to rotate, thereby repeatedly knocking and vibrating the bottom of the box body 9, so that the material will not accumulate inside the box body 9 and will not easily cause blockage.

[0036] Example 2

[0037] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a hopper 3 is detachably fixedly installed on the top of the box body 9, a vacuum cleaner 5 is installed on the top of the base 1, and the output end of the vacuum cleaner 5 is fixedly connected to a dust suction pipe 6, and part of the dust suction pipe 6 is located inside the hopper 3. A cover plate 4 is movably hinged on the top of the hopper 3. Through the arrangement of structures such as the hopper 3 and the vacuum cleaner 5, when the concrete is crushed, a certain amount of dust will be generated, or some small particles will splash and injure people. Therefore, a cover plate 4 is installed on the top of the hopper 3, and a vacuum cleaner 5 is arranged on one side of the hopper 3. The cover plate 4 can cover the hopper 3 to prevent the splashing objects from flying out, and the vacuum cleaner 5 can also absorb the dust.

[0038] In this embodiment, when the concrete block is crushed, large dust will be generated, and some small splashes will also be released, which is dangerous for the staff. Therefore, a vacuum cleaner 5 is provided on one side of the box body 9. When the equipment is working, the vacuum cleaner 5 is turned on to absorb the dust so that the dust will not be exposed to the air. When the concrete block is placed in the hopper 3, the cover plate 4 can be covered so that no splashes will fly out to cause harm to the staff. The hopper 3 is detachable, so that subsequent disassembly and maintenance are also convenient.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
