[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a recycled concrete waste crushing device, when crushing concrete waste, starts the drive motor 14. The output end of the drive motor 14 drives the drive wheel 15 to rotate. The drive wheel 15 drives the driven wheel 17 to rotate through the connecting belt 16. The driven wheel 17 drives the rotating wheel 18 to drive the flywheel 20 to rotate. The rotating wheel 18 drives the breaker hammer 19 to rotate around the rotating wheel 18 and swing in the mounting groove opened in the rotating wheel 18. Then, the worker puts the concrete waste into the upper box 4 through the feed pipe 21. The concrete waste enters the upper box 4 between the crushed stone plate 13 and the rotating wheel 18 and the breaker hammer 19. The rotating wheel 18 drives the breaker hammer 19 to hit the large pieces of concrete waste onto the crushed stone plate 13 and crush them until the concrete waste is crushed to the point that it can pass through the gap between the rotating wheel 18 and the main body of the crushing device 1 and be discharged into the main body of the crushing device 1 through the screen plate 12, thus completing the crushing and recycling of concrete waste.

[0022] After the concrete waste is crushed, the drive motor 14 is turned off. Twisting the movable plate 11 drives the connecting shaft 10 and the recessed block 9, which in turn drives the locking screw 8 to rotate on the mounting column 7 via threads. The locking screw 8 reverses, causing the recessed block 9 to move away from the mounting column 7. The limiting plate 6 is no longer locked in the limiting groove opened in the main body 1 of the crushing device by the mounting column 7 and the locking screw 8. Then, the movable plate 11 is pulled to slide on the top of the upper housing 4 until the connecting shaft 10 slides to one side of the oblong hole opened in the movable plate 11. Then, the movable plate 11 is pulled to rotate on the recessed block 9 with the connecting shaft 10 as the axis until it is perpendicular to the recessed block 9, pushing the movable plate 11... 1. Pushing the concave block 9 drives the locking screw 8 to push the mounting column 7 to push the limiting plate 6 away from the mounting hole opened in the upper box 4. The upper box 4 is no longer locked to the crushing device body 1 by the movable plate 11 in conjunction with the connecting shaft 10, the concave block 9 and the locking screw 8. Pulling the feed pipe 21 drives one side of the upper box 4 to lift upward. The upper box 4 drives the fixing rod 3 to slide upward in the groove opened in the fixing block 2. Then lift the other side of the upper box 4 and rotate it on the fixing block 2 with the fixing rod 3 installed on the upper box 4 as the axis to open it. Thus, the upper box 4 is lifted and opened on the crushing device body 1, which makes it convenient for the staff to clean the inside of the crushing device body 1.

[0023] Example 2, as Figures 2-4 As shown, a recycled concrete waste crushing device allows for convenient cleaning of the interior of the crushing device body 1 and easy maintenance of the crushing stone plate 13 after the upper housing 4 is opened, ensuring the crushing effect of the device on concrete waste. After cleaning and maintenance of the interior of the crushing device body 1, the upper housing 4 is pulled to rotate the fixing rod 3 on the fixing block 2, closing the upper housing 4, which then covers the crushing device body 1 again. Then, the limiting plate 6 is pushed, driving the mounting column 7 to drive the locking screw 8. The locking screw 8 drives the concave block 9 to drive the connecting shaft 10, pushing the movable plate 11, which is perpendicular to the concave block 9, through the mounting hole in the upper housing 4 again. The limiting plate 6 then enters the crushing device body 1. Inside the limiting groove, push the movable plate 11 flat on one side of the top of the upper box 4, then push the movable plate 11 to slide on one side of the top of the upper box 4. At this time, the connecting shaft 10 slides to the side of the waist-shaped hole opened in the movable plate 11. The connecting shaft 10 is located in the middle section of the movable plate 11. Then, turn the movable plate 11 to drive the connecting shaft 10 and the concave block 9, and drive the locking screw 8 to drive the mounting column 7 through the thread to drive the limiting plate 6. Thus, the movable plate 11, together with the connecting shaft 10, the concave block 9 and the locking screw 8, locks the mounting column 7 to drive the limiting plate 6. The limiting plate 6 abuts against the top of the inner wall of the limiting groove opened in the main body of the crushing device 1, thus the upper box 4 and the main body of the crushing device 1 are tightly fitted and fixed.

[0024] It should be noted that the utility model is a kind of recycled concrete waste crushing device, when using, by screwing movable plate 11 drive connecting shaft 10 and recessed block 9 drive locking screw 8 move on mounting column 7 by thread, to lock or release upper box 4 and crushing device main body 1, when movable plate 11 loosens, by pushing movable plate 11 slide on upper box 4 after rotating vertically on recessed block 9 on connecting shaft 10, the mounting hole opened in upper box 4 is separated, then lift upper box 4 drive fixed rod 3 rise in the sliding slot of fixed block 2 and open, upper box 4 does not have to completely separate from crushing device main body 1, subsequent closing is convenient, using fixed block 2 and fixed rod 3 as connection compared with traditional hinged connection in upper box 4 and crushing device main body 1 closed not under stress, reduce the wear and tear of connecting place, prolong service life, and by locking assembly 5 can quickly lock or close upper box 4 and crushing device main body 1, it is convenient to clean and overhaul the inside of crushing device main body 1.

[0025] The basic principles and main features of the utility model and the advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
