DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , the utility model provides a technical solution: a waste concrete garbage fine crushing device, including a base 1 and two crushing mechanisms;

[0020] The front and rear ends of the upper surface of the base 1 are respectively vertically fixedly connected with a front bracket 3 and a rear bracket 2, and two crushing mechanisms are respectively arranged at the top ends of the front bracket 3 and the rear bracket 2;

[0021] The structures of the two crushing mechanisms are the same, one of which includes a crushing frame 4 fixedly connected to the top of the rear bracket 2, the top and bottom ends of the crushing frame 4 are respectively vertically penetrated with a feed port 5 and a discharge port 6, one side of the interior of the crushing frame 4 is fixedly connected to a fixed crushing seat 7, and the other side of the interior of the crushing frame 4 is laterally slidably connected to a sliding crushing seat 8, the outer surface of the crushing frame 4 located on one side of the sliding crushing seat 8 is fixedly connected to an extension frame 9, and the interior of the extension frame 9 is laterally rotatably connected to a crankshaft 11, the outer surfaces of multiple connecting rods of the crankshaft 11 are all rotatably connected to connecting rods 13, the other ends of the multiple connecting rods 13 are all rotatably connected to connecting seats 12, and the other ends of the multiple connecting seats 12 are fixedly connected to driving blocks 10, which can slidably penetrate the side surface of the crushing frame 4 and extend into the interior thereof, and the inner end of the driving block 10 is fixedly connected to the outer surface of the sliding crushing seat 8.

[0022] When the crushing mechanism is in operation, the crankshaft 11 will rotate, and the multiple connecting rods on the crankshaft 11 will drive the connecting rods 13 to move. One end of the multiple connecting rods 13 will perform circular motion under the action of the crankshaft 11, while the other end thereof is restricted by the connecting seat 12 and the driving block 10 and can only perform lateral motion. Therefore, the other end thereof will continue to perform lateral reciprocating motion, thereby driving the sliding crushing seat 8 fixedly connected thereto to perform lateral reciprocating motion back and forth. During the movement of the sliding crushing seat 8, the concrete blocks located between it and the fixed crushing seat 7 will be smashed into small pieces by the impact force, thereby achieving a crushing effect.

[0023] A plurality of reinforcing ribs 14 are fixedly connected between the outer surface of the extension frame 9 and the outer surface of the crushing frame 4 .

[0024] The plurality of reinforcing ribs 14 can improve the connection stability and connection strength between the extension frame 9 and the crushing frame 4, thereby improving the overall stability of the device.

[0025] A motor 18 is fixedly connected to the rear end surface of the extension frame 9 , and an output shaft of the motor 18 rotatably passes through the extension frame 9 and is fixedly connected to one end of the crankshaft 11 .

[0026] When the motor 18 is running, the rotation of its output shaft can drive the crankshaft 11 to rotate, thereby driving the crushing mechanism of the device to operate and provide power for the crushing mechanism of the device.

[0027] The height of the front bracket 3 is lower than that of the rear bracket 2 , and a plurality of guide bars 15 are fixedly connected between the bottom end of the rear crushing mechanism and the top end of the front crushing mechanism, and the plurality of guide bars 15 are evenly spaced along the width direction of the crushing frame 4 .

[0028] A plurality of guide bars 15 are fixedly connected at the bottom of the high crushing mechanism and the top of the low crushing mechanism. There is a certain interval between the plurality of guide bars 15. The small concrete blocks that meet the volume requirements can be screened out through the intervals, and those that do not meet the requirements will be guided into another crushing mechanism through the guide bars 15, so that they can be crushed for the second time, without the need for repeated manual operations, thereby improving the work efficiency of the entire crushing operation.

[0029] A guide plate 16 having the same inclination angle as the plurality of guide strips 15 is fixedly connected between the front bracket 3 and the rear bracket 2 .

[0030] The screened concrete blocks will pass through the gaps between the plurality of guide strips 15 and fall onto the guide plate 15 , and then continue to fall under the guidance of the guide plate 15 .

[0031] Baffles 17 are fixedly connected to both side surfaces of the guide plate 16 along the length direction thereof.

[0032] The baffles 17 on both sides can prevent the falling concrete fragments from splashing randomly and play a shielding role.

[0033] When the device is in operation, the device is provided with two crushing mechanisms, and one is high and the other is low. A plurality of guide bars 15 are fixedly connected to the bottom of the high crushing mechanism and the top of the low crushing mechanism. There is a certain interval between the plurality of guide bars 15. Small concrete blocks that meet the volume requirements can be screened out through the intervals, and those that do not meet the requirements will be guided into another crushing mechanism through the guide bars 15, so that they can be crushed for the second time, without the need for repeated manual operations, thereby improving the work efficiency of the entire crushing operation.
