[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-4 As shown, a concrete block crusher for construction includes a crusher body 1, a feed port 2 is installed on the top of the crusher body 1, a protective mechanism 3 is installed inside the feed port 2, a fixing mechanism 4 is installed at the front of the feed port 2, the protective mechanism 3 includes a fixing block 5, the fixing block 5 is fixedly installed at the top of the feed port 2 near the rear end, a baffle 6 is movably installed inside the feed port 2, a rotating rod 7 is installed at the rear of the baffle 6 and through the inner walls on both sides of the feed port 2, transmission disks 8 are fixedly installed on both sides of the feed port 2 near the top, and springs 9 are installed on the outer periphery of the rotating rod 7 near both ends and inside the two transmission disks 8.
[0023] In this embodiment, the feed port 2 is located at the top of the crusher body 1 and is inclined, and the baffle 6 is located inside the feed port 2 and is matched with each other. The concrete blocks enter the crusher body 1 through the feed port 2 for crushing, and the baffle 6 can reduce the diffusion of dust outward.
[0024] In this embodiment, the baffle 6 is movably rotatably arranged inside the feed port 2 via a rotating rod 7, and the top of the baffle 6 is in contact with the bottom of the fixed block 5 at the rear end. The rotation of the baffle 6 facilitates the addition of concrete blocks and the closing of the feed port 2.
[0025] In this embodiment, the rotating rod 7 passes through the interior of the transmission disk 8 and is movably rotatable. The two ends of the spring 9 are respectively fixedly mounted on the outer periphery of the rotating rod 7 and the inner wall of the transmission disk 8. The rotating rod 7 is rotated with the baffle 6 to be parallel to the feed port 2 under the force of the spring 9, so as to facilitate the automatic closing of the feed port 2 after feeding.
[0026] In this embodiment, the fixing mechanism 4 includes a fixing tube 10, which is fixedly installed at the front part of the feed port 2. A screw 11 is movably installed inside the fixing tube 10, and sliders 12 are movably installed on the outer periphery of the screw 11 at both ends. A knob 13 is fixedly installed at one end of the screw 11. Positioning grooves 14 are provided on both sides of the feed port 2 near the top. Blocks 15 are installed on the inner sides of the two sliders 12 and in the positioning grooves 14. By rotating the knob 13, the slider 12 drives the block 15 to slide into the positioning groove 14 and is located at the bottom of the baffle 6, which is convenient for locking the baffle 6 and preventing external debris from entering after use.
[0027] In this embodiment, the thread directions at both ends of the outer periphery of the screw rod 11 are arranged in opposite directions, and the slider 12 is threadedly connected to the screw rod 11. The two sliders 12 slide oppositely or toward each other through the threads of the screw rod 11 to adjust the locking state of the baffle 6.
[0028] In this embodiment, the two positioning grooves 14 are arranged parallel to the bottom of the baffle 6, and the clamping block 15 passes through the positioning grooves 14 and is arranged to match each other. The clamping block 15 slides through the positioning grooves 14 to the bottom of the baffle 6 to fix the baffle 6 and reduce the entry of external debris.
[0029] It should be noted that the utility model is a concrete block crusher for construction. When in use, first add the concrete block from the feed port 2 to the inside of the crusher body 1, and crush the concrete block by the pressure roller. When adding material, the concrete block contacts the baffle 6, and the baffle 6 rotates and opens under the action of gravity. When the concrete block completely enters the inside of the crusher body 1, the rotating rod 7 drives the baffle 6 to rotate under the force of the spring 9, so that the baffle 6 rotates to its original position, and the feed port 2 is closed, thereby reducing the outward diffusion of dust and the splashing of particles. When the use is over, the screw 11 is rotated by rotating the knob 13, and the two sliders 12 slide inwardly under the action of the screw 11 thread, so that the block 15 passes through the positioning groove 14 and is located at the bottom of the baffle 6, so that the baffle 6 is fixed, thereby preventing external debris from falling in.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
