Technical Field
[0001] The utility model relates to the technical field of concrete processing, in particular to a waste material recovery device for concrete block production. Background Art
[0002] Concrete blocks are a type of man-made building material used in construction and structural engineering. They are usually molded after mixing cement, sand, gravel or other aggregates, and water. However, defective products are inevitable in the production process of concrete blocks, and these defective products need to be recycled for secondary use.
[0003] After extensive research, it was discovered that in the recycling of concrete blocks, defective blocks are generally crushed into powder and then reused. However, although general crushing barrels are equipped with single or multiple blades for crushing, the blocks will fall downward due to gravity, resulting in a decrease in the crushing effect.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a waste recycling device for concrete block production, comprising a processing barrel 1. A cover plate 4 is detachably mounted on the top of the processing barrel 1 by bolts. The cover plate 4 can be removed by tightening the bolts for easy cleaning or maintenance. A motor 3 is fixedly mounted on the top of the cover plate 4. The motor 3 is a prior art. By starting the motor 3, its output shaft drives the rotating rod 6 to rotate. The output shaft of the motor 3 is fixedly mounted with a rotating rod 6. The rotating rod 6 drives the cutting blade 7 to rotate to cut the blocks. A screening assembly for screening the building blocks is provided inside, and a discharge assembly for discharging the crushed building blocks is provided at the bottom of the processing barrel 1. The screening assembly includes a U-shaped block 82, which is fixedly connected to the inner wall of the processing barrel 1. The inner wall of the U-shaped block 82 is slidably connected to a moving block 85, and the moving block 85 can slide vertically on the inner wall of the U-shaped block 82. A recycling assembly is provided on the outer wall of the rotating rod 6, and a feeding pipe 2 is provided on the right side of the processing barrel 1. The waste building blocks to be recycled are put into the processing barrel 1 through the feeding pipe 2.
[0030] Reference Figure 1 - Figure 3The screening assembly also includes a screen plate 81, which is fixedly connected to the rear surface of the moving block 85. The moving block 85 is used to support the screen plate 81. A lower arc surface 87 is provided on the left side of the screen plate 81. By providing the lower arc surface 87, the blocks are dropped downward along the arc surface onto another screen plate 81. The middle part of the screen plate 81 is provided with a plurality of sieve holes 86. The sieve holes 86 drop the crushed dust downward and discharge it through the discharge chute 91 to avoid accumulation in the processing barrel 1. The bottom of the moving block 85 is fixedly connected with an elastic telescopic rod 84. The elastic telescopic rod 84 is a sliding connection between two sleeve rods, and the two sleeve rods are elastically connected. Since this technology is a prior art and can be implemented by technicians in this field, it will not be described in detail in this case. The reverse force of the elastic telescopic rod 84 resets the moving block 85, so that the screen plate 81 vibrates to screen the blocks. The bottom of the elastic telescopic rod 84 is fixedly connected to the inner wall of the lower part of the U-shaped block 82. There are multiple groups of screening components, which are vertically distributed inside the processing barrel 1.
[0031] Reference Figure 1 - Figure 3 The recycling component includes a cutting knife 7, which is fixedly connected to the outer wall of the rotating rod 6. The blanking component includes a connecting rod 92, which is fixedly connected to the inner wall of the processing barrel 1 and is multiple in number. The connecting rod 92 plays a supporting role. The ends of the multiple connecting rods 92 away from the processing barrel 1 are jointly fixedly connected with a blanking block 93. The rotating rod 6 is rotatably connected to the top of the blanking block 93. The blanking block 93 is set to a flat-top cone to prevent the dust after crushing from accumulating on the blanking block 93. A blanking trough 91 is provided at the center adjacent to the blanking block 93 and the processing barrel 1. The dust after crushing can be discharged through the blanking trough 91, and it is set in a circle. The outer wall of the processing barrel 1 is fixedly connected with a support leg 5, which is used to support the processing barrel 1.
[0032] Working principle: When in use, first move the device to a suitable position and support the processing barrel 1 with the support legs 5. When processing is required, the broken concrete bricks are put into the processing barrel 1 through the feed pipe 2, and the motor 3 is started at this time. When the motor 3 is started, its output shaft will drive the rotating rod 6 to rotate, and the rotating rod 6 will drive the cutting knife 7 to rotate. The concrete bricks are cut by the cutting knife 7, and when the bricks fall onto the screen plate 81, the screen plate 81 will be under pressure and move downward to squeeze the elastic telescopic rod 84. After being under pressure, the elastic telescopic rod 84 is reset by its own reverse force, so that the screen plate 81 shakes to achieve the purpose of screening, and the lower arc surface 87 set by the screen plate 81 can make the bricks fall downward along the arc surface to another screen plate 81, thereby increasing the movement stroke of the bricks and increasing the cutting time of the cutting knife 7, thereby improving the efficiency of the recycling work.
[0033] During cutting and crushing, small bricks will directly fall downward through the sieve hole 86 and finally be discharged through the provided discharge chute 91. Even if they fall on the discharge block 93, they will slide downward due to their flat-top conical shape and finally be discharged through the discharge chute 91 to prevent accumulation in the processing barrel 1.
[0034] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
