[0011] Preferably, one end of the extrusion crushing mechanism is connected to the swing shaft, and the other end of the extrusion crushing mechanism is connected to the tail connecting shaft. The tail connecting shaft is installed on the top of the equipment support frame, and the shaft of the tail connecting shaft passes through the side wall of the waste crushing chamber and is connected to the extrusion crushing mechanism. When the transmission gear reciprocates, it drives the swing shaft to reciprocate, which in turn drives the swing shaft to swing synchronously. When the swing shaft swings, it drives the extrusion and crushing mechanism to swing synchronously. When the extrusion and crushing mechanism reciprocates, it can extrude and hammer the construction waste.

[0012] Preferably, the extrusion crushing mechanism includes a limiting sleeve, one end of which is connected to a swing shaft, and the other end of which is connected to a tail connecting shaft.

[0015] A method for recycling construction waste, using the aforementioned construction waste recycling equipment.

[0016] Compared with the prior art, the present invention provides a construction waste recycling device and a method for recycling construction waste, which has the following beneficial effects: 1. In this type of construction waste recycling equipment, when the reverse and forward waste crushing blocks hammer the construction waste, the limiting sleeve continues to rotate when the reverse or forward waste crushing blocks come into contact with the metal material, while the reverse or forward waste crushing blocks cannot continue to move. When the limiting sleeve continues to rotate and the reverse or forward waste crushing blocks cannot move, the reverse and forward waste crushing blocks can slide closer to each other. Through the elastic structure between the reverse and forward waste crushing blocks, the squeezing force on the construction waste is increased when the reverse or forward waste crushing blocks come into contact with the metal material in the construction waste, thereby squeezing and crushing the construction waste and separating it from the metal material.

[0017] 2. This type of construction waste recycling equipment, when the power turntable rotates, can drive the transverse moving groove to reciprocate laterally along the outside of the moving limit slide groove through the external transmission connecting block. When the transverse moving groove moves laterally, it can drive the transverse transmission rack to move synchronously. The outside of the transverse transmission rack meshes with the transmission gear. When the transverse transmission rack moves, it can drive the transmission gear to rotate. The reciprocating lateral movement of the transverse transmission rack can also drive the transmission gear to oscillate back and forth. When the transmission gear oscillates back and forth, it can drive the oscillating shaft to oscillate synchronously. When the oscillating shaft oscillates, it can drive the extrusion and crushing mechanism to oscillate synchronously. When the extrusion and crushing mechanism oscillates, it can alternately drive the reverse waste crushing block and the forward waste crushing block to hammer the construction waste. By driving the extrusion and crushing mechanism to oscillate back and forth to hammer the construction waste through the crushing drive mechanism, it can prevent the reverse waste crushing block and the forward waste crushing block from jamming during the crushing and recycling of construction waste.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a construction waste recycling device and a method for recycling construction waste.

[0022] Example 1: Please see Figure 1 - Figure 12 A construction waste recycling device includes an equipment support frame 1 and a waste crushing chamber 2. The waste crushing chamber 2 is installed inside the equipment support frame 1. A crushing drive mechanism 6 is connected to the outside of the waste crushing chamber 2. A compression crushing mechanism 7 is connected inside the crushing drive mechanism 6. The compression crushing mechanism 7 is rotatably installed inside the waste crushing chamber 2 through the crushing drive mechanism 6. The crushing drive mechanism 6 includes a power turntable 64, a transverse transmission rack 68, and a transmission gear 69. When the power turntable 64 rotates, it can drive the transverse transmission rack 68 to reciprocate laterally. When the transverse transmission rack 68 moves laterally, it can drive the transmission gear 69 to swing back and forth. When the transmission gear 69 swings back and forth, it can drive the crushing mechanism 7 to swing synchronously. The extrusion crushing mechanism 7 includes a reverse waste crushing block 74 and a forward waste crushing block 79, which are slidably connected. When the extrusion crushing mechanism 7 swings, it can drive the reverse waste crushing block 74 and the forward waste crushing block 79 to extrude and hammer the construction waste inside the waste crushing chamber 2. The reverse waste crushing block 74 and the forward waste crushing block 79 are slidably connected. When the reverse waste crushing block 74 or the forward waste crushing block 79 comes into contact with the metal in the construction waste, the reverse waste crushing block 74 and the forward waste crushing block 79 can slide and contract against each other.

[0023] During operation, the construction waste to be crushed and recycled is first placed into the waste crushing chamber 2. Then, the crushing drive mechanism 6 is activated. When the power turntable 64 inside the crushing drive mechanism 6 rotates, it drives the transverse transmission rack 68 to reciprocate. When the transverse transmission rack 68 reciprocates, it drives the transmission gear 69 to swing back and forth. When the transmission gear 69 swings, it drives the extrusion crushing mechanism 7 to swing synchronously. When the extrusion crushing mechanism 7 swings, it drives the reverse waste crushing block 74 and the forward waste crushing block 79 to hammer the waste inside the waste crushing chamber 2. When the crushing drive mechanism 6 drives the extrusion crushing mechanism 7 to rotate clockwise, it drives the forward waste crushing block 79 to hammer and crush the construction waste. When rotated counterclockwise, the reverse waste crushing block 74 can hammer and squeeze the construction waste. When the reverse waste crushing block 74 and the forward waste crushing block 79 encounter metal materials during the crushing and squeezing process, they can slide against each other. This sliding between the reverse waste crushing block 74 and the forward waste crushing block 79 can prevent the metal materials in the construction waste from damaging the reverse waste crushing block 74 or the forward waste crushing block 79. Furthermore, while the reverse waste crushing block 74 and the forward waste crushing block 79 are sliding, the crushing mechanism 7 continues to rotate, which can gradually increase the squeezing force of the reverse waste crushing block 74 and the forward waste crushing block 79 on the construction waste, thereby causing the construction waste to be broken into pieces.

[0024] Example 2: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 Waste discharge outlet 3 is provided at the bottom of the waste crushing bin 2, and a top cover plate 4 is rotatably installed on the top of the waste crushing bin 2. A cover plate telescopic rod 5 is connected to the outside of the top cover plate 4, and a waste baffle 8 is installed inside the waste crushing bin 2. The other end of the cover plate telescopic rod 5 is connected to the equipment support frame 1. The cover plate telescopic rod 5 can drive the top cover plate 4 to rotate on the top of the waste crushing chamber 2 to close the top of the waste crushing chamber 2. The outside of the waste block 8 is in contact with the outside of the extrusion crushing mechanism 7.

[0025] The crushing drive mechanism 6 also includes a power transmission base 61, which is fixedly installed on the top of the equipment support frame 1. A drive motor 62 is connected to the outside of the power transmission base 61, and a power shaft 63 is rotatably installed inside the power transmission base 61. The other end of the power shaft 63 is connected to a power turntable 64, and a transmission connecting block 65 is installed on the outside of the power turntable 64. A moving limit slide groove 66 is installed on the inner side wall of the waste crushing chamber 2, and a transverse moving groove 67 is slidably installed on the top of the moving limit slide groove 66. A transverse transmission rack 68 is connected to the outside of the transverse moving groove 67. A swing transmission chamber 611 is installed on the inner side wall of the waste crushing chamber 2, and a swing shaft 610 is rotatably installed inside the swing transmission chamber 611. One end of the swing shaft 610 is connected to a transmission gear 69, and the other end of the swing shaft 610 is connected to the extrusion crushing mechanism 7. A tail connecting shaft 612 is connected to the outside of the extrusion crushing mechanism 7.

[0026] One end of the power shaft 63 is connected to the drive end of the drive motor 62 through the inside of the power transmission seat 61, and the other end of the power shaft 63 passes through the side wall of the waste crushing chamber 2 and is connected to the power turntable 64. The drive motor 62 can drive the power shaft 63 to rotate through the power transmission base 61, and when the power shaft 63 rotates, it can drive the power turntable 64 to rotate synchronously.

[0027] The outside of the power turntable 64 is connected to the transverse moving groove 67 through the transmission connecting block 65. The outside of the transverse transmission rack 68 meshes with the outside of the transmission gear 69. The transverse transmission rack 68 is slidably mounted on the top of the moving limit slide groove 66 through the transverse moving groove 67. When the power turntable 64 rotates, it can drive the transverse moving groove 67 to move laterally back and forth along the top of the moving limit slide groove 66 through the transmission connection of the transmission connecting block 65 and the transverse moving groove 67. When the transverse moving groove 67 moves, it can drive the transverse transmission rack 68 to move synchronously. When the transverse transmission rack 68 moves laterally back and forth, it can drive the transmission gear 69 to swing cyclically. When the transmission gear 69 rotates, it can drive the swing shaft 610 to rotate synchronously.

[0028] One end of the extrusion crushing mechanism 7 is connected to the swing shaft 610, and the other end of the extrusion crushing mechanism 7 is connected to the tail connecting shaft 612. The tail connecting shaft 612 is installed on the top of the equipment support frame 1, and the shaft of the tail connecting shaft 612 passes through the side wall of the waste crushing chamber 2 and is connected to the extrusion crushing mechanism 7. When the transmission gear 69 reciprocates, it drives the swing shaft 610 to reciprocate, which in turn drives the swing shaft 610 to swing synchronously. When the swing shaft 610 swings, it drives the extrusion and crushing mechanism 7 to swing synchronously. When the extrusion and crushing mechanism 7 reciprocates, it can extrude and crush the construction waste.

[0029] When crushing and recycling construction waste, the cover plate telescopic rod 5 can drive the top cover plate 4 to rotate on top of the waste crushing chamber 2 to cover the top of the waste crushing chamber 2, preventing the construction waste debris from flying out when the crushing mechanism 7 crushes and hammers the construction waste. When recycling construction waste, the drive motor 62 can drive the power shaft 63 to rotate through the power transmission seat 61. When the power shaft 63 rotates, it can drive the power turntable 64 to rotate synchronously. When the power turntable 64 rotates, it can drive the transverse moving groove 67 to reciprocate laterally along the outside of the moving limit slide groove 66 through the external transmission connecting block 65. When the transverse moving groove 67 moves laterally, it can drive the transverse transmission rack 68 to move synchronously. The outside of the transverse transmission rack 68 meshes with the transmission gear 69. When the transverse transmission rack 68 moves, it can drive the transmission gear 69 to rotate. The reciprocating lateral movement of the transverse transmission rack 68 can also drive the transmission gear 69 to reciprocate. The ring oscillation mechanism 69 drives the oscillating shaft 610 to oscillate synchronously when the transmission gear 69 oscillates. When the oscillating shaft 610 oscillates, it drives the extrusion crushing mechanism 7 to oscillate synchronously. When the extrusion crushing mechanism 7 oscillates, it alternately drives the reverse waste crushing block 74 and the forward waste crushing block 79 to hammer the construction waste. The waste baffle 8 at the bottom of the extrusion crushing mechanism 7 can limit the position of the construction waste, preventing it from falling into the dead angle of the reverse waste crushing block 74 and the forward waste crushing block 79. It can also discharge the construction waste through the inclined structure. After being hammered by the reverse waste crushing block 74 and the forward waste crushing block 79, the smaller construction waste is discharged from the inside of the waste crushing chamber 2 through the waste discharge outlet 3. The extrusion crushing mechanism 7 is driven by the crushing drive mechanism 6 to oscillate back and forth to hammer the construction waste, which can prevent the reverse waste crushing block 74 and the forward waste crushing block 79 from getting stuck when crushing and recycling the construction waste.

[0030] Example 3: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The extrusion crushing mechanism 7 includes a limiting sleeve 71. One end of the limiting sleeve 71 is connected to the swing shaft 610, and the other end of the limiting sleeve 71 is connected to the tail connecting shaft 612. An internal connecting shaft 72 is installed inside the limiting sleeve 71. An external rotating ring 73 is rotatably installed outside the internal connecting shaft 72. A reverse waste crushing block 74 is connected to the outside of the external rotating ring 73. A reverse crushing block baffle 75 is provided outside the reverse waste crushing block 74. A sliding connecting baffle 76 is provided outside the reverse waste crushing block 74. A connecting spring 77 is installed inside the reverse waste crushing block 74. An internal rotating ring 78 is installed outside the internal connecting shaft 72. A forward waste crushing block 79 is connected to the outside of the internal rotating ring 78. A forward crushing block baffle 710 is provided outside the forward waste crushing block 79.

[0031] The limiting sleeve 71 has a slot on its outside. The bottoms of the reverse waste crushing block 74 and the forward waste crushing block 79 pass through the slot provided in the limiting sleeve 71 and are rotatably connected to the internal connecting shaft 72 through the outer rotating ring 73 and the inner rotating ring 78. When the swing shaft 610 drives the limit sleeve 71 to swing back and forth, it can drive the reverse waste crushing block 74 and the forward waste crushing block 79 to squeeze and hammer the construction waste inside the waste crushing chamber 2.

[0032] The reverse waste crushing block 74 and the forward waste crushing block 79 are slidably connected by a connecting spring 77. The forward waste crushing block 79 is slidably installed inside the sliding connecting baffle 76. The reverse crushing block baffle 75 on the reverse waste crushing block 74 is in contact with the inside of the limiting sleeve 71. The forward crushing block baffle 710 on the forward waste crushing block 79 is in contact with the inside of the limiting sleeve 71. The limiting sleeve 71 drives the reverse waste crushing block 74 and the forward waste crushing block 79 to squeeze and hammer the construction waste. When the waste comes into contact with metal, the elastic structure between the reverse waste crushing block 74 and the forward waste crushing block 79 can bring them closer to each other.

[0033] During operation, the swing shaft 610 drives the limiting sleeve 71 to reciprocate. When the limiting sleeve 71 reciprocates, it drives the reverse waste crushing block 74 and the forward waste crushing block 79 to hammer the construction waste. When the limiting sleeve 71 rotates clockwise, it drives the forward waste crushing block 79 to hammer and compress the construction waste. When the limiting sleeve 71 rotates counterclockwise, it drives the reverse waste crushing block 74 to hammer and compress the construction waste. During the hammering of the construction waste by the reverse waste crushing block 74 and the forward waste crushing block 79, either the reverse waste crushing block 74 or the forward waste crushing block 79 interacts with the metal... When materials come into contact, the limiting sleeve 71 continues to rotate while the reverse waste crushing block 74 or the forward waste crushing block 79 cannot move further. When the limiting sleeve 71 continues to rotate and the reverse waste crushing block 74 or the forward waste crushing block 79 cannot move, the reverse waste crushing block 74 and the forward waste crushing block 79 can slide closer to each other. When the reverse waste crushing block 74 or the forward waste crushing block 79 approach each other, the reverse waste crushing block 74 can rotate around the internal connecting shaft 72 via the outer rotating ring 73, while the forward waste crushing block 79 can rotate around the internal connecting shaft 72 via the inner rotating ring 78. When the waste crushing block 74 and the forward waste crushing block 79 approach each other, the connecting spring 77 is compressed, thereby increasing the squeezing force of the reverse waste crushing block 74 or the forward waste crushing block 79 on the construction waste. This increased squeezing force allows the construction waste to be crushed as a whole, preventing metal materials from getting stuck between the reverse waste crushing block 74 or the forward waste crushing block 79. Furthermore, when the reverse waste crushing block 74 and the forward waste crushing block 79 slide against each other, the sliding connecting baffle 76 prevents debris from getting stuck in the reverse waste crushing block. Between the waste crushing block 74 and the forward waste crushing block 79, and between the reverse crushing block baffle 75 and the forward crushing block baffle 710, the slots on the limiting sleeve 71 can be sealed when the reverse waste crushing block 74 or the forward waste crushing block 79 rotates, preventing the debris of construction waste from entering the interior of the limiting sleeve 71. The elastic structure between the reverse waste crushing block 74 and the forward waste crushing block 79 can increase the squeezing force on the construction waste when the reverse waste crushing block 74 or the forward waste crushing block 79 comes into contact with the metal material in the construction waste, thereby squeezing and crushing the construction waste and separating it from the metal material.

[0034] Example 4: A method for recycling construction waste, using a construction waste recycling device as described in Examples 1 to 3, includes the following steps: First, the construction waste that needs to be recycled is placed inside the waste crushing chamber 2, and the top of the waste crushing chamber 2 is sealed by the top cover plate 4; Then, the crushing drive mechanism 6 drives the extrusion crushing mechanism 7 to swing and hammer and crush the construction waste inside the waste crushing chamber 2. The reverse waste crushing block 74 and the forward waste crushing block 79 can slide against each other when they encounter metal materials while hammering construction waste, increasing the squeezing force on the construction waste. The shredded construction waste can be discharged from the waste discharge outlet 3.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
