[0017] (III) Beneficial effects

[0018] The device for making bricks from construction waste and automatically separating iron products and impurities has the following beneficial effects:

[0019] 1. The automatic brick-making device for separating iron products and impurities from construction waste is first poured into the heating frame from the upper part of the separation box, and then the heating plate in the heating frame is started to heat the construction waste. After heating for a period of time, the driving motor can be started to drive the turntable and the installation column to rotate. When the installation column rotates one circle, it will slide in the sliding frame and move the sliding frame and the L-shaped rod to push the heating frame to move up and down. When the heating frame slides up and down, the small gear on the front end face of the inner wall support shaft will first mesh with the rack on the right side wall of the rack frame, thereby driving the support shaft to rotate and the transmission belt to move. When the belt is driven horizontally, it will pull the crushing rod to move horizontally through the installation rod, and as the heating frame continues to move upward, the small gear will mesh with the rack on the left side of the rack frame to drive the crushing rod to move horizontally. When the dynamic support shaft is reversed, the transmission belt can move to the left, so that it pulls the crushing rod to slide and reset. When the heating frame moves up and down, it can drive the crushing rod to slide left and right to crush the construction waste, and the steel bars in the building concrete can be broken and separated. The heating of the heating frame will also cause the concrete cement blocks in the construction waste to lose internal moisture and reduce the strength of the concrete, making it easier to be broken. In addition, the heating frame can be moved up and down to make the internal construction waste roll over, so that it can fully contact the magnetic rod when it shakes upward, so as to make the crushed steel bars more easily adsorbed on the outer wall of the magnetic rod, avoiding the phenomenon that the concrete and steel bars in the construction waste are tied together and difficult to be separated.

[0020] 2. The automatic brick-making device for separating iron products and impurities from building waste bricks has the following advantages: when the heating frame moves up and down, the guide rod on the left side thereof will also slide up and down accordingly; when the guide rod moves upward, it will push the triangular plate on the left side to slide to the left and compress the spring telescopic long rod; when the triangular plate slides to the left, it will drive the slide plate and the sliding shaft to slide to the left synchronously; when the sliding shaft moves to the left, it will squeeze the groove wall of the two-way spiral groove column to rotate; when the two-way spiral groove column rotates, it will drive the fan blades to rotate and generate wind force; the building waste moved upward and lifted can be blown; the plastic and sound insulation cotton contained in the building waste can be blown into the unloading frame; and when the guide rod moves downward, it will no longer resist the triangular plate; at this time, the spring telescopic long rod will reset to push the sliding shaft to continuously squeeze the two-way spiral groove column to rotate, and then it can continuously drive the fan blades to rotate and blow away the plastic waste, thereby achieving the effect of separating iron products and plastic waste at the same time, avoiding the trouble of subsequent secondary screening of building waste, saving the cost of separating building waste bricks, and accelerating the work efficiency of subsequent brick making;

[0021] 3. The automatic iron product impurity separation brick making device for building waste brick making, when it is necessary to clean the building waste inside the heating frame and the unloading frame, the spring telescopic pull rod can be stepped on downward to pull the connecting rod to rotate, and when the connecting rod moves downward, the upper end thereof will be pulled to slide the plug plate forward, and because the sliding rod on the left side wall of the plug plate is located on the rear end face of the bottom plate, the bottom plate can be pulled out together with the plug plate sliding forward, and the building waste on the inner wall of the heating frame and the unloading frame can be dropped out together, which not only saves the trouble of the staff to open the receiving materials step by step, but also speeds up the unloading speed, and facilitates the subsequent continuous separation of building waste;

[0022] 4. The automatic iron product impurity separation brick making device for construction waste brick making, and the construction waste will fall on the upper part of the conveyor belt mechanism after unloading. By placing the collection bag inside the brick making box first, the plastic waste that falls first is collected, and the construction waste that is subsequently conveyed can directly enter the brick making box for the next step of brick making operation, so there is no need for manual movement, which improves the convenience of using the entire automatic iron product impurity separation brick making device;

[0023] 5. The automatic brick-making device for separating iron products and impurities from construction waste bricks will pull the rope at the rear to move left when the triangular plate moves left and right repeatedly and drive the installation shaft to rotate. When the installation shaft rotates, it will drive the spiral strip to rotate and the clockwork spring on the outer wall to contract. When the spiral strip rotates, its spiral trajectory will drive the valve stem in the middle to rotate and open the valve in the water pipe, so that water mist can be sprayed while shaking the construction waste upward, and the rope is no longer pulled when the triangular plate is reset to the right, and the clockwork spring will reset and rebound to drive the installation shaft to reverse again, so that the spiral strip can re-move the valve stem to reset and close the valve, thereby achieving the effect of intermittent spraying and dust reduction, which can effectively suppress the phenomenon of dust being raised while crushing and separating iron products, and combined with intermittent spraying and dust reduction, it can reduce the waste of water resources.

[0051] Embodiment 4

[0052] See also Figure 2 and Figure 7 and Figure 8The intermittent spraying dust reduction mechanism 8 includes a water tank 81, a water pump is arranged in the water tank 81, the water outlet of the water pump is connected to a water pipe 82, the front end face of the water pipe 82 is connected to a spray pipe 83, the spray pipe 83 is fixedly connected to the inner cavity wall of the separation box 1, the rear end face of the separation box 1 is rotatably connected to a mounting shaft 84, the outer wall of the mounting shaft 84 is fixedly connected to a spiral strip 85, a valve stem 86 is arranged on the outer wall of the water pipe 82, a spring 87 is wound around the outer wall of the mounting shaft 84, the end of the spring 87 away from the mounting shaft 84 is fixedly connected to the rear end face of the separation box 1, a rope 88 is wound around the outer wall of the mounting shaft 84, the end of the rope 88 away from the mounting shaft 84 is fixedly connected to the rear end face of the triangular plate 65.

[0053] When the triangle plate 65 moves left and right repeatedly, the rope 88 at the rear will be pulled to the left and the installation shaft 84 will be driven to rotate. When the installation shaft 84 rotates, the spiral strip 85 will be driven to rotate and the spring spring 87 on the outer wall will contract. When the spiral strip 85 rotates, its spiral trajectory will drive the valve rod 86 located in the middle to rotate and open the valve in the water pipe 82, so that water mist can be sprayed while shaking the construction waste upward, and when the triangle plate 65 is reset to the right, the rope 88 is no longer pulled. At this time, the spring spring 87 resets and rebounds, which will drive the installation shaft 84 to reverse again, so that the spiral strip 85 can re-move the valve rod 86 to reset and close the valve, thereby achieving the effect of intermittent spraying and dust reduction, which can effectively suppress the phenomenon of dust being raised while crushing and separating iron products, and combined with intermittent spraying and dust reduction, it can reduce the waste of water resources.

[0054] The following is the entire working process of the above 1 to 4 embodiments:

[0055] First, pour the construction waste from the upper part of the separation box 1 into the heating frame 41, and then start the heating plate in the heating frame 41 to heat the construction waste. After heating for a period of time, the driving motor 411 can be started to drive the turntable 412 and the mounting column 413 to rotate. When the mounting column 413 rotates one circle, it will slide in the sliding frame 414 and move the sliding frame 414 and the L-shaped rod 415 to push the heating frame 41 to move up and down. When the heating frame 41 slides up and down, the small gear 47 on the front end face of the inner wall support shaft 44 will first engage the rack on the right side wall of the rack frame 48, thereby driving the support shaft 44 to rotate and the transmission belt 45 to move. When the belt 45 is transmitted horizontally, it will pull the crushing rod 43 to move horizontally through the mounting rod 46, and as the heating frame 41 continues to move upward, the small gear 47 will engage the rack on the left side of the rack frame 48 and thereby drive the support shaft 44 to reverse, so that the transmission belt 45 can move to the left, so that it can pull the crushing rod 43 to slide and reset, and the crushing rod 43 can be driven left and right while the heating frame 41 moves up and down. The construction waste can be crushed by sliding, and the steel bars in the construction concrete can be broken and separated. The heating of the heating frame 41 can also make the concrete cement blocks in the construction waste lose internal moisture and reduce the strength of the concrete, so that it is easier to be crushed. In addition, the heating frame 41 can be moved up and down to make the internal construction waste roll over, so that it can fully contact the magnetic rod 410 when shaking upward, so that the crushed steel bars are more easily adsorbed on the outer wall of the magnetic rod 410, avoiding the phenomenon that the concrete and steel bars in the construction waste are tied together and difficult to be separated.

[0056] When the heating frame 41 moves up and down, the guide rod 416 on the left side will also slide up and down accordingly. When the guide rod 416 moves upward, it will push the triangular plate 65 on the left side to slide to the left and compress the spring telescopic long rod 63. When the triangular plate 65 slides to the left, it will drive the slide plate 64 and the sliding shaft 66 to slide to the left synchronously. The sliding shaft 66 will squeeze the groove wall of the two-way spiral groove column 61 to rotate. When the two-way spiral groove column 61 rotates, it will drive the fan blade 62 to rotate and generate wind force, which can blow the construction waste moved upward and lifted, and can blow the plastic and sound insulation cotton contained in the construction waste into the unloading frame 5. When the guide rod 416 moves downward, it no longer resists the triangular plate 65. At this time, the spring telescopic long rod 63 resets and pushes the sliding shaft 66 to continue to squeeze the two-way spiral groove column 61 to rotate, and then can continue to drive the fan blade 62 to rotate to blow away the plastic waste, thereby achieving the effect of separating iron products and plastic waste at the same time, avoiding the trouble of secondary screening of construction waste in the subsequent process, saving the cost of separating construction waste bricks, and accelerating the subsequent brick making work efficiency;

[0057] When it is necessary to clean the construction waste inside the heating frame 41 and the blanking frame 5, the pressure plate 76 can be stepped on downward to press the spring telescopic pull rod 71 to contract and pull the connecting rod 73 to rotate. When the connecting rod 73 moves downward, the upper end thereof will be pulled to slide the plug plate 72 forward, and because the sliding rod 74 on the left side wall of the plug plate 72 is located at the rear end surface of the bottom plate 417, the bottom plate 417 can be pulled out together with the plug plate 72 sliding forward, so that the heating frame 41 and the construction waste on the inner wall of the blanking frame 5 can fall out together, which not only saves the trouble of the staff to open the receiving materials step by step, but also speeds up the unloading speed, and facilitates the subsequent continuous separation of construction waste.

[0058] After unloading, the construction waste will fall on the upper part of the conveyor belt mechanism 75. By placing the collection bag inside the brick making box 2, the plastic waste that falls first is collected, and the construction waste that is subsequently conveyed can directly enter the brick making box 2 for the next step of brick making operation, so there is no need for manual movement, which improves the convenience of using the entire automatic separation of iron impurities brick making device;

[0059] When the triangle plate 65 moves left and right repeatedly, the rope 88 at the rear will be pulled to the left and the installation shaft 84 will be driven to rotate. When the installation shaft 84 rotates, the spiral strip 85 will be driven to rotate and the spring spring 87 on the outer wall will contract. When the spiral strip 85 rotates, its spiral trajectory will drive the valve rod 86 located in the middle to rotate and open the valve in the water pipe 82, so that water mist can be sprayed while shaking the construction waste upward, and when the triangle plate 65 is reset to the right, the rope 88 is no longer pulled. At this time, the spring spring 87 resets and rebounds, which will drive the installation shaft 84 to reverse again, so that the spiral strip 85 can re-move the valve rod 86 to reset and close the valve, thereby achieving the effect of intermittent spraying and dust reduction, which can effectively suppress the phenomenon of dust being raised while crushing and separating iron products, and combined with intermittent spraying and dust reduction, it can reduce the waste of water resources.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
