Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, in particular to a concrete waste recycling device. Background Art

[0002] When construction is in progress at a construction site, a lot of concrete waste will be generated. After being processed by a recycling device, these concrete wastes can be recycled again, which can effectively reduce the waste of building materials.

[0003] After searching, it was found that patent announcement number CN118287210A discloses an impact crusher that is easy to maintain and is used for crushing and recycling concrete waste. The invention moves the moving plate close to the compression and extension component, squeezes and drives the T-frame to move into the slot through the compression and extension component, and the impact spring is gradually compressed, and the toothed plate 1 moves synchronously with the T-frame. When the T-frame contacts the pressure block, the T-frame squeezes the pressure block and drives the toothed plate 2 to move into the slot, and then the toothed plates 1 and 2 are quickly ejected, so that the toothed plates 1 and 2 can impact and crush the raw materials.

[0004] However, although the recycling device can achieve a good crushing effect on concrete waste in actual use, it still has many defects, such as:

[0005] 1. When the moving plate in the recycling device squeezes the lower pressing plate, it is easy to cause wear on the contact part between the moving plate and the lower pressing plate, which causes the staff to frequently shut down the recycling device for maintenance, resulting in a reduction in the recycling efficiency of the recycling device for raw materials;

[0006] 2. Although the toothed plates 1 and 2 in the recycling device can have a good impact crushing effect on the raw materials, the impact points of the toothed plates 1 and 2 on the raw materials are large, which results in poor recycling efficiency when the raw materials are crushed inside the recycling device;

[0007] 3. The recycling device is not equipped with a good dust cleaning structure. When the toothed plates 1 and 2 crush the raw materials for recycling, the dust generated by the crushing of the raw materials is easy to contact the impact spring and the tension spring. If the dust around the impact spring and the tension spring cannot be cleaned in time, it is easy to cause the impact spring and the tension spring to be damaged;

[0008] To this end, we propose a concrete waste recycling device. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-3 , 5-7, 10, the present invention provides a technical solution:

[0042] A concrete waste recycling device includes a shell structure 1 and a rotating shaft 8 rotatably connected to the inside of the shell structure 1, a rotating frame 4 is sleeved on the rotating shaft 8, and further includes:

[0043] The sliding plate 6 is arranged inside the housing structure 1, and the sliding plate 6 is sleeved with the rotating shaft 8. The sliding plate 6 is provided with a sliding mechanism 15. The rotating frame 4 is provided with mounting blocks 7 at equal intervals. The middle of the mounting block 7 is provided with a sliding cavity 74 and a mounting cavity 71. The sliding mechanism 15 includes a pushing magnetic block 55, and the pushing magnetic block 55 is arranged inside the sliding cavity 74.

[0044] A plurality of impact rods 9 are plugged into the mounting block 7, one end of the impact rod 9 passes through the mounting block 7 and is inserted into the interior of the mounting cavity 71, one end of the impact rod 9 inserted into the mounting cavity 71 is fixedly connected to a magnetic block end 92, an extrusion spring 91 is sleeved on the impact rod 9, the extrusion spring 91 is fixed between the mounting block 7 and the magnetic block end 92, and an ejection mechanism 14 is distributed inside the mounting cavity 71, the ejection mechanism 14 includes a moving magnetic block 99 distributed on one side of the magnetic block end 92, the moving magnetic block 99 has opposite magnetic poles to the magnetic block end 92 and the pushing magnetic block 55, when the pushing magnetic block 55 moves into the sliding cavity 74, the pushing magnetic block 55 drives the moving magnetic block 99 to move backward in the rotation direction, so that the moving magnetic block 99 drives the impact rod 9 to move into the interior of the mounting cavity 71 one by one through the magnetic block end 92, and then the extrusion spring 91 drives the impact rod 9 to impact the concrete waste through the magnetic block end 92 in turn;

[0045] It should be supplemented that the stimulation of the moving magnet 99 and the magnet end 92 repels each other. When the moving magnet 99 in the recovery device is close to the magnet end 92, the magnet end 92 can drive the impact rod 9 to shrink toward the inside of the installation cavity 71. At this time, the extrusion spring 91 accumulates force to work. When the moving magnet 99 is separated from the magnet end 92, the repulsive force generated by the extrusion spring 91 will drive the impact rod 9 to reset, so that the impact rod 9 can crush the concrete waste and realize the recycling of concrete waste.

[0046] Example 2: Please refer to Figure 1-6 , 9, 11, the present invention provides a technical solution:

[0047] A connecting tube 11 passes through the rotating frame 4, the upper end of the connecting tube 11 is clamped with the mounting block 7, and the lower end of the connecting tube 11 is clamped with the rotating shaft 8. The sliding mechanism 15 also includes a plug-in strip 51, and an air guide cavity 54 is provided at the lower end of the plug-in strip 51. The air guide cavity 54 is connected with the inner cavity of the rotating shaft 8 through the connecting tube 11, and the air of the rotating shaft 8 can be guided to the inside of the mounting cavity 71, so that the air inside the mounting cavity 71 is discharged through the gap between the impact rod 9 and the mounting block 7.

[0048] The plug strip 51 can be inserted into the sliding cavity 74, the pushing magnetic block 55 is distributed on one side of the plug strip 51 close to the installation cavity 71, the two sides of the plug strip 51 close to the air guide cavity 54 are rotatably connected with the rotating arc plate 53, the inner wall of the installation cavity 71 close to the pushing magnetic block 55 is fixedly connected with the baffle member 75, the inner wall of the installation cavity 71 close to the installation cavity 71 is provided with a collecting cavity 72, and the inside of the collecting cavity 72 is fixedly connected with a sticky pad 73;

[0049] The rotating frame 4 is provided with an inserting hole 41, the connecting pipe 11 is arranged inside the inserting hole 41, and the sliding cavity 74 is rotatably connected with a rotating circular plate 12 located above the connecting pipe 11;

[0050] When the rotating frame 4 in the recovery device drives the mounting block 7 to rotate, the plug-in strip 51 can move inside the sliding cavity 74. When the plug-in strip 51 moves up, the cavity at the lower part of the sliding cavity 74 is in a negative pressure state. At this time, the rotating circular plate 12 will flip upward, and the air inside the rotating shaft 8 will pass through the connecting pipe 11 and enter the sliding cavity 74. When the plug-in strip 51 moves down, the cavity at the lower part of the sliding cavity 74 is in a high pressure state. At this time, the air inside the air guide cavity 54 will drive the rotating arc plate 53 to flip upward. At the same time, high-pressure air will enter the upper part of the mounting cavity 71 and the sliding cavity 74. The heaviest air will pass through the gap between the plug-in strip 51 and the sliding cavity 74 and the gap between the impact rod 9 and the mounting block 7, so as to realize the discharge of dust on the surface of the plug-in strip 51 and the impact rod 9.

[0051] Example 3: Please refer to Figure 1-12 , the present invention provides a technical solution:

[0052] The inner cavity of the mounting cavity 71 is provided with a sliding rod 96, one end of the sliding rod 96 is fixedly connected to a fixing seat 97, the other end of the sliding rod 96 is fixedly connected to a mounting plate 93, the fixing seat 97 and the mounting plate 93 are both fixedly connected to the mounting cavity 71, a sliding seat 98 is slidably connected to the sliding rod 96, a mounting frame 94 is fixedly connected to the sliding seat 98, and the mounting frame 94 is fixedly connected to a movable magnetic block 99.

[0053] A return spring 95 is sleeved on the sliding rod 96, one end of the return spring 95 is fixedly connected to the sliding seat 98, and the other end of the return spring 95 is fixedly connected to the fixed seat 97. A traction rope 910 passes through the fixed seat 97, one end of the traction rope 910 is fixedly connected to the sliding seat 98, and a fixing plate 911 passes through the traction rope 910, and the fixing plate 911 is fixedly connected to the inner wall of the installation cavity 71.

[0054] The bottom wall of the installation cavity 71 is fixedly connected to a storage shell 133, and the interior of the storage shell 133 is rotatably connected to a rotating rod 136, and the rotating rod 136 is fixedly connected to a winding rod 134, and the outer wall of the winding rod 134 is fixedly connected to the traction rope 910, and a coil spring 135 is fixedly connected between the rotating rod 136 and the storage shell 133.

[0055] One end of the wrapping rod 134 away from the rotating rod 136 is fixedly connected to the limit baffle 131 , the limit baffle 131 is fixedly connected to the rotating rod 13 , and a rotating magnet 132 penetrates the rotating rod 13 .

[0056] One end of the rotating shaft 8 is fixedly connected to a filter screen plate 10, which is distributed outside the shell structure 1. The other end of the rotating shaft 8 is fixedly connected to the output shaft of the external motor. The first impact plate 2 and the second impact plate 3 are fixedly connected to the inside of the shell structure 1 near the mounting block 7.

[0057] The sliding plate 6 is provided with a plug-in slot 63, and the sliding plate 6 is sleeved on the rotating shaft 8 through the plug-in slot 63. A mounting circular plate 61 is fixedly connected to one side of the sliding plate 6, and a track slot 62 is provided on the other side of the sliding plate 6. The track slot 62 is internally slidably connected to a limit rod 52, and the limit rod 52 is fixedly connected to a push plate 5, and the push plate 5 is fixedly connected to the plug-in strip 51;

[0058] When the output shaft of the external motor drives the rotating shaft 8 to rotate, the rotating shaft 8 can drive the mounting block 7 to rotate through the rotating frame 4. At this time, the pushing plate 5 can drive the limiting rod 52 to slide inside the track groove 62 on the sliding plate 6. It should be supplemented that the curved portion of the upper part of the track groove 62 is opposite to the first impact plate 2. When the limiting rod 52 slides inside the track groove 62, the pushing plate 5 can drive the plug-in strip 51 to slide up and down inside the sliding cavity 74. When the pushing magnetic block 55 approaches the rotating magnetic block 132, the rotating magnetic block 132 can drive the rotating rod 13 to rotate. At this time, the rotating rod 136 can drive the coil spring 135 When the coil spring 135 is in the reset state, the coil spring 135 can drive the rotating rod 13 on the winding rod 134 to rotate through the rotating rod 136, so as to realize the reset of the rotating magnetic block 132. At the same time, the winding rod 134 can reel in the traction rope 910, and the traction rope 910 can drive the sliding seat 98 on the mounting frame 94 to move on the sliding rod 96. At this time, the moving magnetic block 99 can be close to the magnetic block end 92, so as to realize the movement of the impact rods 9 on the mounting block 7 one by one. When the sliding seat 98 moves on the sliding rod 96, the reset spring 95 can store power to work, and the repulsive force generated by the reset spring 95 can drive the sliding seat 98 to reset.

[0059] When the impact rod 9 cooperates with the pushing plate 5 to impact the concrete waste, the concrete waste can collide with the first impact plate 2 and the second impact plate 3. At this time, the concrete waste can be crushed around the first impact plate 2 and the second impact plate 3. When the crushed concrete waste collides with the impact rod 9, the deformation generated by the extrusion spring 91 cooperates with the repulsive force generated by the moving magnetic block 99 to realize the downward movement of the impact rod 9. Subsequently, the repulsive force generated by the extrusion spring 91 can drive the impact rod 9 to quickly break the concrete waste, thereby realizing the recycling of concrete waste.
