[0012] The present invention is further configured such that: a splash guard is fitted and installed at the top of the suction housing, and a suction bucket shell is fixed to the top of the suction housing by bolt threads.

[0013] Through the above technical solution, the anti-splash net prevents the concrete block from splashing when it breaks, and the suction bucket shell sucks the inside of the suction shell, so that a negative pressure environment is formed in the crushing chamber.

[0014] The present invention is further configured such that: a telescopic hose is fixed to the top of the suction bucket shell by bolt threads, and a suction filter is fixedly installed at one end of the telescopic hose.

[0015] Through the above technical solution, the suction filter uses a telescopic hose to suction the crushing chamber, and the collected dust is transported through a pipeline to a dust recovery device for centralized processing and reuse.

[0016] The present invention is further configured such that: the crushing mechanism includes a mounting shell fixed to one side of the crushing shell, a mounting motor is fixedly mounted on the inner wall of the mounting shell, and the output shaft of the mounting motor is fixedly connected to a drive gear through a coupling.

[0017] The above technical solution involves installing a motor to drive the drive gear to rotate, and installing a housing for isolation and protection.

[0018] The present invention is further configured such that: a first crushing roller is fixedly installed at one end of the driving gear and extends through and into the interior of the crushing housing; a second crushing roller is rotatably installed inside the crushing housing; a driven gear is fixedly installed at one end of the second crushing roller; and the outer surface of the driving gear meshes with the outer surface of the driven gear.

[0019] Through the above technical solution, the driving gear drives the first crushing roller to rotate, and the driving gear drives the second crushing roller to rotate in the opposite direction through the driven gear.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, by incorporating a dust removal mechanism, creates a relatively enclosed space within the suction housing, isolating the crushing process from the external environment. Simultaneously, the suction filter creates a negative pressure environment within the enclosed crushing chamber, transporting the collected dust through pipelines to a dust recovery device for centralized processing and reuse, thereby reducing dust leakage and minimizing the impact on the environment and the health of operators.

[0022] 2. This utility model, by incorporating a crushing mechanism, can crush concrete blocks, enabling rapid processing of large quantities of concrete waste. This meets the timeliness requirements for concrete processing in engineering construction, provides uniform crushing results, facilitates subsequent screening and reuse of particle sizes, and improves the recycling rate of concrete waste.

[0029] Please see Figures 1-4A concrete crushing device includes a crushing shell 1, a suction shell 2 rotatably mounted on the top of the crushing shell 1, a feeding hopper 3 fixedly mounted on one side of the crushing shell 1, a dust removal mechanism 4 for reducing dust leakage on the outside of the crushing shell 1, the dust removal mechanism 4 including a rubber pad support frame 401 fixed to one side of the crushing shell 1, an electric telescopic rod 402 rotatably mounted between the crushing shell 1 and the suction shell 2, a feeding baffle 403 fixedly mounted inside the feeding hopper 3, a metal rotating plate 404 rotatably mounted on the bottom end of the feeding baffle 403, a splash guard 405 fitted into the top of the suction shell 2, a suction hopper shell 406 fixedly bolted to the top of the suction shell 2, a telescopic hose 407 fixedly bolted to the top of the suction hopper shell 406, and a suction filter 408 fixedly mounted on one end of each telescopic hose 407. Concrete blocks enter the suction shell 2 through the feeding hopper 3. The concrete is then crushed and discharged inside the crushing shell 1, facilitating subsequent screening and reuse. The electric telescopic rod 402 controls the suction shell 2 to fold ninety degrees over the crushing shell 1. A rubber pad support frame 401 limits and supports the folded suction shell 2, facilitating maintenance and repair of the interior of the crushing shell 1. A feed baffle 403 prevents concrete blocks from falling onto the suction shell 2. A metal rotating plate 404 seals the opening of the suction shell 2, allowing concrete blocks to fall into the crushing shell 1 while preventing dust from escaping from the opening. A splash guard 405 prevents splashing during concrete block crushing. A suction filter 408 draws suction from the crushing chamber via a telescopic hose 407. A suction bucket 406 draws suction from the interior of the suction shell 2, creating a negative pressure environment within the crushing chamber. The collected dust is then transported through pipelines to a dust recovery device for centralized processing and reuse.

[0030] like Figure 4 As shown, a crushing mechanism 5 capable of rapidly processing large quantities of concrete waste is provided on one side of the crushing housing 1. The crushing mechanism 5 includes a mounting shell 501 fixed to one side of the crushing housing 1. A mounting motor 502 is fixedly mounted on the inner wall of the mounting shell 501. The output shaft of the mounting motor 502 is fixedly connected to a drive gear 503 via a coupling. A first crushing roller 504 penetrating and extending into the interior of the crushing housing 1 is fixedly mounted at one end of the drive gear 503. A second crushing roller 505 is rotatably mounted inside the crushing housing 1. A driven gear 506 is fixedly mounted at one end of the second crushing roller 505. The outer surface of the drive gear 503 meshes with the outer surface of the driven gear 506. The mounting motor 502 drives the drive gear 503 to rotate.

The drive gear 503 drives the second crushing roller 505 to rotate in the opposite direction via the driven gear 506, so that the first crushing roller 504 and the second crushing roller 505 crush the concrete blocks.

[0031] In use, concrete blocks enter the suction housing 2 through the feed hopper 3. The feed baffle 403 prevents concrete blocks from falling onto the suction housing 2. The metal rotating plate 404 seals the opening of the suction housing 2, facilitating the entry of concrete blocks into the crushing housing 1 while preventing dust from escaping from the opening.

The suction filter 408 uses a telescopic hose 407 to suction the inside of the crushing chamber. The suction bucket shell 406 suctions the inside of the suction shell 2, creating a negative pressure environment inside the crushing chamber. The collected dust is transported through pipelines to the dust recovery device for centralized processing and reuse. When maintaining and repairing the inside of the crushing shell 1, the extension and retraction of the electric telescopic rod 402 controls the suction shell 2 to fold ninety degrees through the crushing shell 1. The rubber pad support frame 401 limits and supports the folded suction shell 2, thereby enabling maintenance and repair of the inside of the crushing shell 1.
