Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushing equipment, and more specifically to a concrete recycling and crushing device. Background Art
[0002] Concrete recycling crushing device is a kind of mechanical equipment specially used to process waste concrete so that it can be reused. Jaw crusher is a common crushing equipment, which mainly realizes the crushing of materials through the relative movement of the moving jaw plate and the fixed jaw plate.
[0003] Concrete is made of cement, sand, gravel, water and admixtures mixed in proportion. Because cement is a powdery substance, and there is fine powder on the surface of sand and gravel aggregates and fine debris produced by mutual friction, a large amount of dust will be generated when the crusher breaks concrete blocks. In addition, the air flow disturbance in the crushing chamber makes it easy for dust to escape, causing dust to fill the workplace. If exposed to this environment for a long time, dust particles enter the respiratory tract with breathing and are easily deposited in multiple parts of the body, causing rhinitis, pharyngitis and other diseases. Long-term inhalation of cement dust containing free silica may also cause pneumoconiosis, which is a great health hazard to operators at the crusher operation site. Utility Model Content

[0025] In this embodiment, a charged plate 81 that can rotate inside the feed port 3 is provided. When the bristles 13 rotate at high speed, static electricity can be generated on the surface of the charged plate 81. When the conveyor belt 8 drives the charged plate 81 to rotate inside the feed port 3, the dust inside the feed port 3 can be adsorbed on the surface of the charged plate 81, which can effectively curb the diffusion of dust in the air, greatly reduce the dust concentration in the working area, create a relatively clean and comfortable operating environment, and reduce the health risks of operators suffering from respiratory diseases.
[0026] Specifically, the discharge assembly 14 includes a fixed seat 141 fixedly connected to the inner wall of the discharge port 51, the fixed seat 141 is rotatably connected to a fixed shaft 142 inside, the outer surface of the fixed shaft 142 is rotatably connected to a rotating rod 143, the surface of the rotating rod 143 is fixedly connected to an elastic band 144, the end of the elastic band 144 away from the rotating rod 143 is fixedly connected to the surface of the fixed seat 141, the top of the surface of the rotating rod 143 is fixedly connected to another fixed shaft 142, the outer surface of the fixed shaft 142 is rotatably connected to a rotating wheel 145, the rotating wheel 145 can contact the charged plate 81 on the conveyor belt 8, and the bottom of the fixed seat 141 is fixedly connected to a wire 146.
[0027] In this embodiment, by providing the discharge assembly 14 , the dust adsorbed on the surface of the charged plate 81 can be accurately dropped from the inside of the discharge port 51 into the input end of the jaw crusher body 1 .
[0028] Specifically, the outer surface of the fixed shaft 142 is fixedly sleeved with a limit ring 1421 and a conductive spring sheet 1422 , the inside of the rotating rod 143 and the rotating wheel 145 is provided with a rotating groove matching the limit ring 1421 , and the surface of the conductive spring sheet 1422 abuts against the inside of the rotating rod 143 and the rotating wheel 145 .
[0029] In this embodiment, by providing the conductive spring piece 1422, the conductivity between the fixed shaft 142 and the rotating rod 143 and the rotating wheel 145 can be enhanced, so that static electricity can be released smoothly, and the adsorbed dust can fall more accurately, thereby enhancing practicality.
[0030] Specifically, the end of the wire 146 is connected to the ground.
[0031] Under normal conditions, the elasticity of the elastic band 144 causes the rotating rod 143 to rotate counterclockwise, and the surface of the rotating wheel 145 abuts against the surface of the charged plate 81 .
[0032] In this embodiment, by providing the elastic band 144 , the rotating wheel 145 can be pressed against the surface of the charged plate 81 .
[0033] Specifically, the fixing seat 141, the fixing shaft 142, the rotating rod 143 and the rotating wheel 145 are all made of aluminum alloy with good electrical conductivity. The charged plate 81 is a flexible rubber plate made of nitrile rubber, and the bristles 13 are made of nylon.
[0034] In this embodiment, due to the materials of the charged plate 81 and the bristles 13, static electricity can be quickly attached to the surface of the charged plate 81 when the two rub against each other.
[0035] Specifically, the interiors of the discharge port 5 and the feed port 51 are both connected to the input end of the jaw crusher body 1 , and the surface of the bristles 13 abuts against the surface of the charged plate 81 .
[0036] In this embodiment, since the surface of the bristles 13 abuts against the surface of the charged plate 81 , the friction between the bristles 13 and the charged plate 81 can be increased.
[0037] The working principle and use process of the utility model are as follows: when in use, a concrete block is placed inside the feed port 3, and then falls to the output end of the jaw crusher body 1 through the discharge port 5 for crushing. When crushing, dust will be lifted up and enter the feed port 3. By starting the motor 9, the motor 9 drives the drum 10 and the brush 13 to rotate at high speed through the pulley 11 and the V-belt 12. The friction between the rotation of the brush 13 and the charged plate 81 causes the surface of the charged plate 81 to be charged with static electricity. At the same time, the motor 9 drives the roller 7 to rotate through the pulley 11 and the V-belt 12. The roller 7 drives the charged plate 81 to rotate at the feed port through the transmission belt 8. When the inside of the feed port 3 rotates, the dust inside the feed port 3 can be adsorbed on the surface of the charged plate 81. When the charged plate 81 rotates to the inside of the discharge port 51, the static electricity on the charged plate 81 is finally led to the ground through the wire 146 through the contact between the impeller 145 and the charged plate 81. At this time, the surface of the charged plate 81 has no static electricity, and the dust adsorbed on the surface falls into the input end of the jaw crusher body 1 through the discharge port 51, which can effectively curb the diffusion of dust in the air, greatly reduce the dust concentration in the working area, create a relatively clean and comfortable operating environment, and reduce the health risks of operators suffering from respiratory diseases.
