[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The crushing mechanism and the crushing auxiliary mechanism are set to crush the waste concrete blocks entering the crushing box at the same time.

At the same time, the second transmission belt drives the driven pulley to rotate, thereby driving the transmission sleeve to rotate, and the transmission sleeve cooperates with the adapter shaft to drive the second reciprocating screw to rotate on the top of the extrusion and pushing block. The second reciprocating screw drives the second connecting block to slide relative to the extrusion and pushing block in the second connecting hole through the thread, thereby driving the two push plates to reciprocate, and intermittently extending multiple crushing top cones from one side of the extrusion and pushing block to insert into the waste concrete block to assist in crushing.

[0022] 3. By setting the crushing top cone to slide back and forth on the surface of the squeezing and pushing block, when the squeezing and pushing block moves away from the stopper, the crushing top cone and the squeezing and pushing block perform relative displacement in the same direction until the tip of the crushing top cone is completely retracted into the circular hole opened in the squeezing and pushing block.

9. A method for using a concrete processing device mixed with waste concrete blocks, characterized in that: A concrete processing device for mixed waste concrete blocks as described in any one of claims 1 to 8 is used, The following steps are involved: S1: First, the servo motor (9) is started. The servo motor (9) drives the three-groove pulley (21) in the equipment box (18) to rotate through the first transmission belt (24). The three-groove pulley (21) drives the two first reciprocating screw rods (11) to rotate through the connecting shaft. The two first reciprocating screw rods (11) drive the two squeezing and pushing blocks (8) to slide continuously and reciprocatingly along the guide rod (10) toward the stopper (7). At the same time, S2 is executed; S2: The three-groove pulley (21) drives the connecting shaft to rotate and drives the driving bevel gear (22) to rotate at the same time. The driving bevel gear (22) drives the driven bevel gear (23) to rotate. The driven bevel gear (23) drives the main shaft (13) to rotate. The main shaft (13) drives the multiple electromagnet shafts (15) to rotate in the channel through which the steel bars pass. The three-groove pulley (21) drives the two driven pulleys (26) to rotate through the two second transmission belts (25). The driven pulley (26) drives the transfer shaft (30). The transfer shaft (30) drives the transmission sleeve (27) to rotate through the limiting convex rafter (3001). Even if the transmission sleeve (27) moves with the squeezing and pushing block (8), the rotational transmission can still be realized, thereby driving the second reciprocating screw (28) to rotate. Then, the second reciprocating screw (28) drives the crushing top cone (2902) in the crushing auxiliary mechanism (29) to extend from the circular hole and insert into the concrete block when the squeezing and pushing block (8) squeezes the concrete block, thereby reducing the crushing pressure of the squeezing and pushing block (8); S3: Then the microcontroller in the main shaft (13) is started to control the storage battery (14) to energize the electromagnet shaft (15) so that all the electromagnet shafts (15) generate magnetism, thereby adsorbing and crushing iron materials such as steel bars in the concrete; S4: Then, the waste concrete blocks are added from the two feeding funnels (4) into the crushing box (2), and three containers for collecting concrete particles are placed under the crushing box (2). The waste concrete blocks are quickly crushed by the continuously reciprocating squeezing and pushing blocks (8) and the crushing auxiliary mechanism (29), and the crushed concrete particles and steel bars fall on the surface of the filter plate (6). The small concrete particles directly pass through the filter plate (6) and are discharged from the bottom of the crushing box (2) and fall into the containers near the two sides. The large concrete particles and steel bars roll along the filter plate (6) toward the iron removal mechanism, and the steel bars are adsorbed by the magnetic electromagnet shaft (15). The large concrete particles fall to the bottom of the crushing box (2) and into the container in the middle.
