Description

Technical Field

[0001] The utility model relates to the technical field of construction waste crushing devices, in particular to a construction waste crusher capable of preventing material jumping. Background Technique

[0002] With the vigorous development of construction, a large amount of construction waste will inevitably be generated during the construction process. In order to facilitate the recycling and reuse of construction waste in the later stage, construction enterprises usually use construction waste crushers to crush and collect construction waste. There are still certain defects in the existing construction waste crushers during use, such as;

[0003] When the construction waste crusher is in use, when encountering some relatively smooth or round construction waste, it is easy to jump when being crushed between the two crushing rollers and is difficult to crush. Most of the existing construction waste crushers do not have a structure to prevent the construction waste from jumping. And most of the existing construction waste crushers use inclined screen vibration for screening. The waste above is easy to press down the waste below, easy to block and difficult to screen, and most of them do not have an anti-blocking structure. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 and Figure 4 , the present utility model provides a technical solution: a construction waste crusher capable of preventing material jumping, including: an outer box 1, a feed box 2, a feeding hopper 3 and a crushing roller 4;

[0026] One side of the outer box 1 is connected through with the feed box 2, one side of the feed box 2 is connected with the feeding hopper 3, and a crushing roller 4 is arranged in the feed box 2; a pushing mechanism 5 is connected above the feed box 2, a screening mechanism 6 is arranged in the outer box 1, a cabinet door 7 is arranged on one side of the outer box 1, and the pushing mechanism 5 includes: an inverted U-shaped frame 501, a cylinder 502, a horizontal plate 503, a pressure sensor 504, a hollow pile 505, a T-shaped sliding rod 506 and a control box 507. The upper surface of the feed box 2 is connected with the inverted U-shaped frame 501 through bolts, the cylinder 502 is connected through in the inverted U-shaped frame 501, and the bottom of the cylinder 502 is connected with the horizontal plate 503.

[0027] A pressure sensor 504 is connected to the bottom of the cross plate 503. A hollow pile 505 is connected to the bottom of the pressure sensor 504. The hollow pile 505 is slidably connected in the feed box 2. A T-shaped slide bar 506 is slidably penetrated through the cross plate 503 away from the pressure sensor 504. The T-shaped slide bar 506 is connected to the upper surface of the hollow pile 505. A control box 507 is connected to one side of the outer box 1. The control box 507 is electrically connected to the pressure sensor 504.

[0028] During specific implementation, construction waste is poured into the feeding hopper 3 and slides into the feed box 2. Then, the control box 507 is operated to start the air cylinder 502 to drive the cross plate 503 to move downward, driving the hollow pile 505 to push the construction waste against the crushing roller 4 to prevent some relatively smooth construction waste from bouncing. When the hollow pile 505 pushes the construction waste, a reaction force is generated to push the hollow pile 505 to drive the T-shaped slide bar 506 to slide in the cross plate 503 for guiding. At the same time, the pressure sensor 504 is squeezed, and the pressure data is transmitted to the control box 507. When the control box 507 detects excessive pressure, it gives a reminder to check whether the construction waste in the feed box 2 is blocked, so as to prevent the material from bouncing in this construction waste crusher.

[0029] Refer to Figures 1-4 As can be seen, the screening mechanism 6 includes: a support plate 601, a filter cylinder 602, a sealing door 603, a driving motor 604, a gear 605, an external tooth ring 606, a convex rod roller 607, and a collection box 608. Two groups of support plates 601 are connected to the inner wall of the outer box 1 by bolts. The filter cylinder 602 is rotatably connected in the two groups of support plates 601 through bearings. The end of the feed box 2 is arranged inside the filter cylinder 602. A sealing door 603 is arranged at one end of the filter cylinder 602 away from the feed box 2. A driving motor 604 is installed on one side of the support plate 601 through a motor base. The output end of the driving motor 604 penetrates through the inner wall of the support plate 601 and is connected to a gear 605. A gear 605 is meshed with an external tooth ring 606 below. The external tooth ring 606 is sleeved and fixed on the outer side of the filter cylinder 602. A convex rod roller 607 is connected to one side of the gear 605 away from the driving motor 604.

The collection box 608 is slidably penetrated through the front part of the inner wall of the outer box 1.

[0030] During specific implementation, start the driving motor 604 to drive the gear 605 to rotate. The gear 605 drives the external gear ring 606 to drive the filter cylinder 602 to rotate within the support plate 601, screening the materials entering the filter cylinder 602. At the same time, the convex rod roller 607 rotates along the outer side of the filter cylinder 602, and the convex rods of the convex rod roller 607 are inserted into the holes of the filter cylinder 602 to push out the waste materials blocked in the holes of the filter cylinder 602. The waste materials screened out by the filter cylinder 602 fall into the collection box 608, and the larger waste materials remain in the filter cylinder 602. Open the cabinet door 7 and the sealing door 603 to take out the remaining waste materials, so as to prevent the building waste crusher from being blocked.

[0031] In summary: When using this building waste crusher that can prevent material bouncing, first, pour the building waste to be crushed into the feeding hopper 3 and slide it into the feeding box 2. Start the motor connected to the crushing roller 4 to drive the two groups of crushing rollers 4 to rotate, crushing the building waste. Start the cylinder 502 to drive the hollow pile 505 to press down the building waste. The crushed building waste slides into the filter cylinder 602. The driving motor 604 drives the filter cylinder 602 to rotate, causing the smaller waste materials to fall into the collection box 608. The convex rod roller 607 pushes out the waste materials blocked in the holes of the filter cylinder 602. Finally, open the cabinet door 7 and the sealing door 603 to take out the remaining waste materials.
