Description

Technical Field

[0001] The invention belongs to the field of waste recycling, in particular to an energy-saving building material waste crushing and recycling processing device. Background Art

[0002] Energy-saving building material waste crushing and recycling equipment is an important tool for processing construction waste and waste and realizing resource recycling. It uses a rotating knife roller to crush and cut the waste, and reduces its volume by breaking the waste so that it can be better recycled.

[0003] The prior art also proposes some solutions. For example, a patent application with authorization announcement number CN215389569U discloses a construction waste crushing device, which includes: a box body, a feed inlet, a crushing roller, a first gear, and a first motor. The application screens the waste so that the waste can be discharged separately, thereby reducing the problem of waste blockage.

[0004] However, during the long-term waste crushing process of the above-mentioned waste crushing device, due to the friction, extrusion and other effects of the waste, some fine waste particles or fragments may adhere to the knife gaps between the crushing blades on the knife roller. If these attached waste materials are not cleaned up in time, they will gradually accumulate to form a thick attachment layer. When the thickness of the waste attachment layer gradually increases, the movement space of the blade will be restricted, resulting in the blade being unable to fully contact the input waste, which directly affects the crushing effect of the blade, making the waste crushing degree uneven, and even failing to achieve the expected crushing effect.

[0016] Preferably, the size of the protrusion matches the size of the groove, and the protrusion can be inserted into the groove.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The energy-saving building material waste crushing and recycling processing equipment described in the present invention acts on the knife gaps of the crushing roller through the blade of the scraper head. The blade of the scraper head contacts the side wall of the knife gap of the crushing roller. After the waste is mixed in the knife gap of the crushing roller, when the crushing roller rotates and passes the position of the scraper head, the scraper head can scrape the waste attached to the knife gap of the crushing roller, thereby preventing the waste from being attached between the knife gaps, causing the crushing blade outside the crushing roller to be unable to effectively contact with the energy-saving building material waste, thereby affecting the crushing effect of the energy-saving building material waste. The problem occurs that when the scraper head contacts thicker waste, the waste will push the scraper head to shrink it, and the scraper head drives the retraction plate and the retraction column to move backward. The retraction plate will squeeze spring 1 to shrink it, and at the same time, the elastic force of spring 1 is used to push the retraction plate so that the scraper head is always in contact with the waste or the side wall of the crushing roller. When the scraper head cannot scrape the waste off the blade gap, the scraper head moves away from the waste and shrinks backward, avoiding the scraper head getting stuck on the waste and causing obstruction, affecting the rotation of the crushing roller or causing the scraper head to collapse.

[0019] 2. The energy-saving building material waste crushing and recycling processing equipment described in the present invention pushes the scraper head through thicker waste to move the retraction plate and the retraction column, and cooperates with the linkage component to drive gear one to rotate. The outer part of gear one has teeth at / , and no teeth at / . Therefore, when the toothed part of gear one meshes with the reciprocating rod, gear one drives the reciprocating rod to move into the injection box, and the piston moves under the thrust of the reciprocating rod, and pulls spring two to extend it, and the piston discharges the air in the injection box from the one-way valve one. When the toothless part of gear one does not mesh with the reciprocating rod, spring two uses its own elastic force to pull the piston to move in the opposite direction, and the piston draws the lubricating oil stored in the oil storage tank into the injection box through the one-way valve two, and waits for the next time when the toothed part of gear one meshes with the reciprocating rod When the reciprocating rod is pushed by the combination to drive the piston to move, the piston injects the pumped lubricating oil into the liquid spraying nozzle through the one-way valve 1, and the liquid spraying nozzle sprays the lubricating oil to the outside of the passing waste material, so as to reduce the adhesion of the waste material, and use the lubrication component to spray the lubricating oil on the waste material at a thicker position, and reduce the adhesion tightness of the waste material by lubrication, so that the scraper head can scrape the waste material better, thereby improving the scraping effect of the waste material. When the thicker waste material is scraped off, the retraction column moves in the opposite direction under the elastic force of the spring 1, and cooperates with the linkage component to still drive the gear 1 to rotate. At this time, when the toothed part of the gear 1 meshes with the reciprocating rod, the reciprocating rod is pulled outward, and the piston moves with the reciprocating rod. Although the lubricating oil in the oil storage tank can be sucked through the one-way valve 2, However, there is still a certain amount of air in the injection box. Even if gear 1 is not engaged with the reciprocating rod, when the piston is pushed to inject lubricating oil by the elastic force of spring 2, only a small amount of lubricating oil can be discharged through the one-way valve 1 and sprayed out by the liquid spray nozzle. The lubricating oil is directly sprayed onto the side wall of the crushing roller. Cooperating with the scraping of the scraper head, it can lubricate the surface of the crushing roller to reduce the adhesion of the waste to the knife gap of the crushing roller and improve the scraping effect of the scraper head. A warning component is installed on the crushing and recycling equipment to electrically connect the switch to the warning component. When the waste cannot be scraped off by the scraper head, if the waste gradually accumulates and becomes thicker, it will push the scraper head to continuously retract. The movement of the scraper head will drive the retraction plate to move with it. When the scraper head is completely retracted to the retraction The cam is in the retraction box and does not extend out from the inner wall of the crushing box. At this time, the fixed cavities on both sides of the retraction plate are directly opposite to the grooves on both sides of the retraction box, and the protrusion loses the pressure effect of the side wall of the retraction box. The spring three pushes the protrusion into the groove, and the protrusion presses the switch in the groove to turn it on. The switch is turned on and the warning component is started to warn the staff that the waste here cannot be effectively removed, and the staff performs the removal operation manually. When the waste here is processed, the retraction plate is pushed by the elastic force of the spring one, and the retraction plate drives the scraper head to reset to the state of contact with the side wall of the crushing roller knife gap again. At the same time, the protrusion moves out of the groove and retracts into the fixed cavity and squeezes the spring three to contract. The switch loses the effect of the protrusion and closes, so that the warning component stops the warning operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9As shown, an energy-saving building material waste crushing and recycling processing equipment according to an embodiment of the present invention includes a crushing box 1, a driving component 2 installed on one side of the crushing box 1, a crushing roller 3 installed inside the crushing box 1, and a feeding hopper 4 fixed on the top of the crushing box 1, a scraper component 5 is arranged on the front and back of the crushing box 1, a lubrication component 6 is arranged on the top of the scraper component 5, a linkage component 7 is arranged between the scraper component 5 and the lubrication component 6, and a touch component 8 is arranged inside the scraper component 5.

[0033] During the long-term waste crushing process, due to the friction and extrusion of the waste, some small waste particles or fragments may adhere to the knife gaps between the crushing blades on the knife roller. If these attached wastes are not cleaned in time, they will gradually accumulate and form a thick attachment layer. When the thickness of the waste attachment layer gradually increases, the movement space of the blade will be restricted, resulting in the blade being unable to fully contact the input waste, which directly affects the crushing effect of the blade, making the waste crushing degree uneven, and even failing to achieve the expected crushing effect;

[0034] A waste box is installed below the crushing box 1, and the driving assembly 2 is started to drive the crushing roller 3 to rotate, and the energy-saving building material waste is put into the feed hopper 4. The energy-saving building material waste is crushed when passing through the rotating crushing roller 3, and the crushed energy-saving building material waste is discharged from the bottom of the crushing box 1 into the waste box, so that the energy-saving building material waste can be recycled;

[0035] The scraper assembly 5 acts between the knife gaps of the crushing roller 3. When the crushing roller 3 rotates, the scraper assembly 5 scrapes away the waste mixed in the knife gaps of the crushing roller 3. By scraping away the waste mixed in the knife gaps, it prevents the waste from adhering to the knife gaps, causing the crushing blades outside the crushing roller 3 to be unable to effectively contact the energy-saving building material waste, thereby affecting the crushing effect of the energy-saving building material waste.

[0036] When the waste material between the knife gaps is thick and cannot be effectively scraped off, the linkage component 7 drives the lubricating component 6, and the lubricating component 6 is used to spray lubricating oil on the waste material at the thicker position, thereby reducing the adhesion of the waste material by lubrication, so that the scraping component 5 can scrape the waste material better, thereby improving the scraping effect of the waste material;

[0037] The touch component 8 is electrically connected to the warning component. When the waste cannot be scraped off, the waste gradually accumulates and becomes thicker, which will push the scraper component 5 to retract. When the scraper component 5 is fully retracted, the warning component is activated in conjunction with the touch component 8 to warn the staff that the waste here cannot be effectively removed and the staff needs to perform manual intervention to remove the waste.

[0038] like Figures 1 to 6As shown, the scraper assembly 5 includes a retraction box 51 fixed to the front and back of the crushing box 1, a retraction plate 54 is arranged inside the retraction box 51, a scraper head 52 is fixed to one end of the retraction plate 54 facing the side wall of the crushing box 1, the scraper head 52 extends from the outer wall of the crushing box 1 to the inner wall of the crushing box 1 and contacts the side wall of the crushing roller 3, a retraction column 53 is fixed to the other end of the retraction plate 54, a spring 55 is arranged outside the retraction column 53, one end of the spring 55 is fixedly connected to the retraction plate 54, and the other end of the spring 55 is fixedly connected to the inner wall of the retraction box 51.

[0039] The blade of the scraper head 52 acts between the blade gaps of the crushing roller 3. The blade of the scraper head 52 contacts the side wall of the blade gap of the crushing roller 3. After the scraps are mixed in the blade gap of the crushing roller 3, when the crushing roller 3 rotates and passes the position of the scraper head 52, the scraper head 52 can scrape the waste attached to the blade gap of the crushing roller 3, so as to prevent the waste from being attached between the blade gaps, resulting in the crushing blade outside the crushing roller 3 being unable to effectively contact the energy-saving building material waste, thereby affecting the crushing effect of the energy-saving building material waste.

[0040] When the scraper head 52 contacts thicker waste, the waste will push the scraper head 52 to shrink it, and the scraper head 52 drives the retraction plate 54 and the retraction column 53 to move backward. The retraction plate 54 will squeeze the spring 55 to shrink it, and at the same time, the elastic force of the spring 55 is used to push the retraction plate 54 so that the scraper head 52 is always in contact with the waste or the side wall of the crushing roller 3. When the scraper head 52 cannot scrape the waste off the knife gap, the scraper head 52 moves away from the waste and shrinks backward, avoiding the scraper head 52 getting stuck on the waste and causing obstruction, affecting the rotation of the crushing roller 3 or causing the scraper head 52 to collapse.

[0041] like Figures 1 to 6As shown, the lubrication assembly 6 includes a pumping box 62 fixed on the top of the retraction box 51, an oil storage tank 61 is arranged above the pumping box 62, a one-way valve 1 63 is installed at one end of the pumping box 62 facing the side wall of the crushing box 1, a liquid spraying nozzle 64 is installed on the one-way valve 1 63, the liquid spraying nozzle 64 extends from the outer wall of the crushing box 1 to the inside thereof and is located above the scraper head 52, a one-way valve 2 67 is installed on the top of the pumping box 62, the top of the one-way valve 2 67 is connected to the inside of the oil storage tank 61, the one-way valve 1 63 can only discharge the lubricating liquid in the pumping box 62, and the one-way valve 2 67 can only It is enough to supply the lubricating liquid in the oil storage tank 61 to enter the pumping box 62. The lubrication assembly 6 also includes a piston 68 arranged inside the pumping box 62. A reciprocating rod 66 is arranged at the other end of the pumping box 62. One end of the reciprocating rod 66 extends from the outside of the pumping box 62 to the inside thereof and is fixedly connected to the piston 68. A spring 2 69 is fixed to one end of the piston 68 facing the reciprocating rod 66. A gear 1 65 is arranged on one side of the reciprocating rod 66. The gear 1 65 is installed at the end of the pumping box 62. One end of the spring 2 69 is fixedly connected to the inner wall of the pumping box 62. The spring 2 69 is wound around the outside of the reciprocating rod 66.

[0042] When the waste material between the knife gaps is thick and cannot be effectively scraped off, the thicker waste material pushes the scraper head 52 to move the retracting plate 54 and the retracting column 53, and cooperates with the linkage assembly 7 to drive the gear 1 65 to rotate. The outer 3 / 4 of the gear 1 65 has teeth, and the 1 / 4 has no teeth. Therefore, when the toothed part of the gear 1 65 is engaged with the reciprocating rod 66, the gear 1 65 drives the reciprocating rod 66 to move into the injection box 62, and the piston 68 is moved by the thrust of the reciprocating rod 66, and the spring 2 69 is pulled to extend it. The piston 68 discharges the air in the injection box 62 from the one-way valve 1 63. When the toothless part of the gear 1 65 is not engaged with the reciprocating rod 66, the spring 2 69 uses its own elastic force The action pulls the piston 68 to move in the opposite direction, and the piston 68 draws the lubricating oil stored in the oil storage tank 61 into the pumping box 62 through the one-way valve 2 67. When the toothed part of the gear 1 65 meshes with the reciprocating rod 66 next time, the reciprocating rod 66 drives the piston 68 to move, and the piston 68 injects the drawn lubricating oil into the liquid spraying nozzle 64 through the one-way valve 1 63. The liquid spraying nozzle 64 sprays the lubricating oil to the outside of the passing waste material, so as to reduce the adhesion of the waste material. The lubricating component 6 is used to spray the lubricating oil on the waste material at a thicker position, and the adhesion of the waste material is reduced by lubrication, so that the scraper head 52 can better scrape the waste material, thereby improving the scraping effect of the waste material.

[0043] It should be noted that the piston 68 is in a process of continuous reciprocating movement inside the pumping box 62. The piston 68 first pushes out the air in the pumping box 62, and then extracts the lubricating oil stored in the oil storage tank 61 and sprays it out through the liquid spray nozzle 64. In addition, the lubricating oil needs to be added to the inside of the oil storage tank 61 in advance. After the thicker waste is scraped off, the retraction column 53 moves in the opposite direction under the elastic force of the spring 55, and the linkage assembly 7 still drives the gear 65 to rotate. At this time, when the toothed part of the gear 65 is engaged with the reciprocating rod 66, the reciprocating rod 66 is pulled outward, and the piston 68 follows. Although the reciprocating rod 66 can move and suck the lubricating oil in the oil storage tank 61 through the one-way valve 67, there is still a certain amount of air in the injection box 62. Even when the gear 65 is not engaged with the reciprocating rod 66, when the piston 68 is pushed by the elastic force of the spring 69 to inject the lubricating oil, only a small amount of lubricating oil can be discharged through the one-way valve 63 and sprayed out by the liquid spraying nozzle 64. The lubricating oil is directly sprayed onto the side wall of the crushing roller 3. Combined with the scraping of the scraper head 52, it can have a certain lubricating effect on the surface of the crushing roller 3, reduce the adhesion of waste materials to the knife gap of the crushing roller 3, and improve the scraping effect of the scraper head 52.

[0044] like Figures 1 to 6 As shown, the linkage assembly 7 includes a tooth plate 71 arranged on one side of the retraction column 53, the tooth plate 71 protrudes from the end of the retraction box 51 and a gear two 72 is arranged on one side thereof, the gear two 72 is installed on the end of the retraction box 51, and a gear three 73 is meshed with one side of the gear two 72, and the gear three 73 is located directly below the gear one 65 and is fixedly connected to the gear one 65.

[0045] When the thicker waste material pushes the scraper head 52 to move the retraction plate 54 and the retraction column 53, the retraction column 53 drives the tooth plate 71 to move, the tooth plate 71 drives the gear two 72 to rotate, the gear two 72 drives the gear three 73 to rotate, and the gear three 73 drives the gear one 65 to rotate. When the retraction column 53 moves backward under the thrust of the waste material, the gear one 65 rotates and drives the reciprocating rod 66 to move into the injection box 62. When the thicker waste material is scraped off, the retraction column 53 moves in the opposite direction under the elastic force of the spring one 55 and drives the tooth plate 71 to move. The tooth plate 71 drives the gear two 72 to rotate in the opposite direction, the gear two 72 drives the gear three 73 to rotate in the opposite direction, and the gear three 73 drives the gear one 65 to rotate in the opposite direction. At this time, the gear one 65 drives the reciprocating rod 66 to move outward.

[0046] like Figures 1 to 9 As shown, the touch assembly 8 includes a fixed cavity 81 opened on both sides of the retracting plate 54, a spring three 85 is fixed inside the fixed cavity 81, a protrusion 84 is fixed at one end of the spring three 85, grooves 82 are opened on both sides of the retracting box 51, a switch 83 is installed inside the groove 82, the size of the protrusion 84 matches the size of the groove 82, and the protrusion 84 can be stuck in the groove 82.

[0047] An alarm component is installed on the crushing and recycling equipment, and the switch 83 is electrically connected to the alarm component. When the scraper head 52 cannot scrape away the waste material, if the waste material gradually accumulates and becomes thicker, the scraper head 52 will be pushed to continuously retract. The movement of the scraper head 52 will drive the retraction plate 54 to move with it. When the scraper head 52 is completely retracted into the retraction box 51 and does not extend from the inner wall of the crushing box 1, at this time, the fixed cavities 81 on both sides of the retraction plate 54 are directly opposite to the grooves 82 on both sides of the retraction box 51, and the protrusion 84 loses the pressure effect of the side wall of the retraction box 51, and the spring 3 85 pushes the protrusion 84 into the groove 82 , the protrusion 84 presses the switch 83 in the groove 82 to turn it on, and the switch 83 is turned on to cooperate with the alarm component to start, so as to warn the staff that the waste here cannot be effectively removed, and the staff performs the removal operation by manual intervention. When the waste here is processed, the retraction plate 54 is pushed by the elastic force of the spring 1 55, and the retraction plate 54 drives the scraper head 52 to reset to the state of contact with the side wall of the knife gap of the crushing roller 3 again. At the same time, the protrusion 84 moves out of the groove 82 and retracts into the fixed cavity 81 and squeezes the spring 3 85 to shrink. The switch 83 loses the effect of the protrusion 84 and closes, so that the alarm component stops the alarm operation.
