Description

Technical Field

[0001] The invention relates to the field of construction waste recycling, and in particular to a construction waste combined extrusion harmless treatment system and method. Background Art

[0002] In the prior art, construction waste is usually handled by loading the waste into a transport vehicle through an excavator, and then the transport vehicle is used to transport the waste to the construction site where road paving is required. Short-distance transportation is more reasonable, but long-distance transportation, such as transporting construction waste generated by urban construction to remote areas for paving roads such as mountainous areas and the northwest region, or transporting it from inland areas to coastal areas for land reclamation, requires long-distance transportation. In this way, if only the excavator is used to pile the debris in the transport vehicle, the space utilization rate of the transport vehicle will be low, which is not conducive to long-distance transportation and leads to increased costs. Traditional equipment rarely uses the method of squeezing construction waste into blocks, and then coating the surface of the construction waste blocks with a layer of special glue to enhance the adhesion of the construction waste and facilitate stacking and transportation.

[0003] The main reason is that the compressed garbage blocks are extremely easy to loosen during transportation, and the gluing process is very difficult. There are two main gluing methods in existing devices, static gluing and dynamic gluing.

[0004] Static gluing, as the name suggests, does not move the construction waste block, and people or equipment apply glue to the exposed surfaces of the construction waste block. The result is that the bottom surface of the construction waste block cannot be glued together, which will inevitably lead to a process of waiting for the first few surfaces to dry before coating the bottom surface, which is extremely inefficient.

[0005] Dynamic gluing, as the name implies, means gluing the construction waste block during its movement. This method can overcome the problem of the bottom surface being difficult to synchronize with static gluing. However, since the construction waste block itself is easy to loosen, in order to avoid the loosening caused by inertia, the waste block can only do simple linear motion, which will make it difficult to glue the surface behind the movement direction during the movement. It will also lead to extremely low gluing efficiency.

[0006] Based on this, the present invention designs a construction waste combined extrusion harmless treatment system and method to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a construction waste combined extrusion harmless treatment system and method thereof, so as to solve the problems of the prior art shortcomings mentioned in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution;

[0009] The harmless treatment system for construction waste combined extrusion comprises a support device, a first conveyor belt, a second conveyor belt and a gantry, wherein the first conveyor belt and the second conveyor belt are both arranged in the support device, and there is a gap between the first conveyor belt and the second conveyor belt, and the characteristic is that the gantry is installed on the support device of the second conveyor belt near one end of the first conveyor belt, a first transmission shaft is rotatably connected inside the gantry, a roller shaft is fixedly connected outside the first transmission shaft, a first rotating arm is rotatably connected above the gantry, an upper pull rod is slidably connected to the first rotating arm, and the first rotating arm and the upper pull rod are also connected by a spring; one end of the second rotating arm is arranged below the gantry, the other end of the second rotating arm is connected to a lower pull rod, and the second rotating arm and the lower pull rod are also connected by a spring, and in addition, torsion springs are arranged between the first rotating arm, the second rotating arm and the gantry;

[0010] A second limit plate and a first limit plate fixedly connected to the gantry are symmetrically arranged on the outer sides of the upper pull rod and the lower pull rod respectively; a first limit groove and a second limit groove are respectively opened in the first limit plate and the second limit plate; the first limit groove is composed of a first process groove, a first stretching groove and a first return groove, wherein the center of the first process groove overlaps with the center of the rotation trajectory of the second rotating arm; the second limit groove is composed of a second process groove, a second stretching groove and a second return groove, wherein the center of the second process groove overlaps with the center of the rotation trajectory of the first rotating arm; the upper pull rod is slidably connected in the second limit groove through a first sliding column fixedly connected thereto; the lower pull rod is slidably connected in the first limit groove through a second sliding column fixedly connected thereto; rollers are rotatably connected between the two upper pull rods and the two lower pull rods.

[0011] When the present invention is used: first, the compressed building waste blocks are transported to the second conveyor belt, and then the second conveyor belt drives the building waste blocks to move and pass through the gantry; when the building waste blocks pass through the gantry, first, the building waste blocks will contact the two rollers on the sides of the gantry, and the rollers will roll under the drive of the building waste blocks, so as to apply glue to the two sides of the building waste blocks; the building waste blocks move further, and the side close to the first conveyor belt will contact the rollers between the lower pull rods, and the building waste blocks push the rollers to drive the rollers to rotate around the rotating connection point between the second rotating arm and the gantry, so that the rollers between the lower pull rods rotate synchronously with the second rotating arm, and at the same time, the building waste blocks facing the first conveyor belt are pressed against the rollers. The oriented surface is coated with glue; since the lower pull rod is connected to the second rotating arm by a spring, and the lower pull rod is slidably connected to the first limit groove on the first limit plate through the second sliding column fixedly connected thereto, during the downward rotation of the lower pull rod, the second sliding column slides along the first process groove, and finally passes the reversing wedge block of the first process groove and enters the first stretching groove. Since the center of the first process groove coincides with point P, the distance between the first sliding column and point P remains unchanged during the downward rotation of the lower pull rod, so the lower pull rod will not be stretched during the downward rotation; when the second sliding column moves to the end of the first process groove, that is, the connection between the first process groove and the first stretching groove, the roller shaft between the lower pull rod and the construction When the lower surface of the construction waste block is separated from the roller shaft between the lower pull rods, the first rotating arm will be reset under the action of the torsion spring, and the first rotating arm will drive the lower pull rod to rotate in the opposite direction. Since the second sliding column fixedly connected to the lower pull rod is located in the first stretching groove at this time, when the first rotating arm drives the lower pull rod to reset, the second sliding column will slide along the first stretching groove, thereby driving the lower pull rod to stretch, thereby compensating for the displacement of the construction waste block toward the first conveyor belt, and also compensating for the horizontal distance difference between the lower pull rod and the construction waste block when rotating around point P; in addition, in the process of the second sliding column moving along the first stretching groove, the lower pull rod is moving away from the first rotating column. The speed of the arm direction movement will gradually increase with the movement of the second slide column in the first stretching groove, that is, it will gradually become faster with the extension speed of the lower pull rod, thereby compensating for the displacement of the lateral distance between the lower pull rod and the building waste block when it rotates around point P; thereby, the side of the building waste block away from the first conveyor belt can be coated with glue; then the second slide column moves into the first return groove, and the roller shaft between the lower pull rod is completely separated from the clamped garbage block. At this time, the second slide column moves to the end of the first stretching groove, that is, the connection between the first stretching groove and the first return groove; then the lower pull rod will be reset under the action of the spring, that is, the lower pull rod is reset by moving along the first return groove toward the direction of the first rotating arm through the second slide column fixedly connected to it;

[0012] Similarly, the upper pull rod above will also perform similar movements with the lower pull rod, thereby completing the gluing of the surface of the construction waste block close to the first conveyor belt, the surface away from the first conveyor belt and the upper surface of the construction waste block; it should be noted that, in the initial state, there is a lateral distance between the rollers on the upper pull rod and the lower pull rod, so this lateral distance can ensure that there is a certain time difference when the upper pull rod and the lower pull rod are working, thereby avoiding interference between the upper pull rod 8 and the lower pull rod when they make a return motion in the corresponding second return groove and the first return groove.

[0013] In addition, since the upper pull rod is longer than the lower pull rod, and the upper pull rod and the lower pull rod are initially staggered, the lower pull rod is closer to the gantry frame than the upper pull rod, and the rotation of the lower pull rod will not interfere with the upper pull rod, so the lower pull rod will first be pushed by the construction waste block to rotate and reset relative to the upper pull rod; and through the characteristics of the upper pull rod and the lower pull rod being staggered and rotating separately, the surface of the construction waste block close to the first conveyor belt and the surface away from the conveyor belt can be completely covered, ensuring that no glue is missed;

[0014] After the construction waste blocks are completely coated with glue, they will move to the next process along the first conveyor belt.

[0015] As a further solution of the present invention, a second scraper plate is fixedly connected to the support device through a connecting column below, and the second scraper plate is provided with an inclination angle from the gear to the second conveyor belt. A first scraper plate is fixedly connected to the gantry through a supporting plate fixedly connected thereto above, and the first scraper plate is also provided with a certain inclination angle; a third scraper plate is fixedly connected to the grooves opened in both sides of the gantry; during operation: since there is still a large amount of dust that is easy to fall off on the surface of the extruded construction waste blocks, when the roller is coating the construction waste blocks with glue, it is inevitable that the dust on the construction waste blocks will be contaminated on the roller, which may cause the circumference of the roller to be covered with dust and unable to continue to coat the construction waste blocks with glue. If the roller is replaced in the middle, the processing line needs to be suspended, which will also reduce the efficiency of the system in coating the construction waste blocks with glue. Therefore, it is hoped that the roller can remove the contaminated dust during the process of coating the construction waste blocks with glue, so as to ensure that during the movement of the construction waste blocks, the system can efficiently coat the six sides of the construction waste with glue; the rotating device The two rollers arranged in the gantry will drive the two rollers to rotate counterclockwise and clockwise respectively through friction when the building waste blocks pass by. Since the third scraper plate is fixedly connected in the gantry, the dust on the two rollers in the gantry will be scraped off by the third scraper plate; similarly, after the rollers between the upper pull rods are pushed upward by the building waste blocks, the rollers between the upper pull rods will be tangent to the first scraper plate. Since the rollers are driven to rotate by the friction generated between the building waste blocks and the rollers, the first scraper plate will scrape off the dust on the rollers between the upper pull rods; similarly, the second scraper fixedly connected to the supporting device through the connecting column can also clean the dust on the rollers between the lower pull rods; thereby ensuring that the contact surface of the rollers with the building waste blocks is always kept clean, thereby ensuring that the building waste blocks will not be missed from coating, and also ensuring that the system can ensure efficient and complete coating of the six surfaces of the building waste blocks during the movement of the building waste blocks without stopping the machine to replace the rollers, thereby improving the working efficiency of the system.

[0016] As a further solution of the present invention, a mounting frame is fixedly connected to the supporting device of the first conveyor belt near one end of the second conveyor belt, and a plurality of gears are rotatably connected to the mounting frame through a rotating shaft, and the plurality of gears are meshed with each other; in addition, identical fans are fixedly connected to the rotating shafts above the gears, and the number of gears is an even number. The rotating shafts above the two outermost gears are also connected to the first transmission shaft through belts; the two first rotating shafts rotatably connected in the gantry are connected by elastic ropes; during operation: since the lower surface of the construction waste block is coated with glue by the roller, if the glue on the lower surface of the construction waste block cannot dry quickly, then when the construction waste block enters the first conveyor belt, the glue on the lower surface of the construction waste block will be smeared on the first conveyor belt, causing the construction waste block to stick to the first conveyor belt, so it is hoped that the contact surface of the construction waste block with the first conveyor belt can dry quickly; when the construction waste block passes through the gantry, it will pass through the two inner sides of the gantry and the construction waste block. The friction between the rollers drives the two rollers to rotate clockwise and counterclockwise respectively, and the two rollers will also stretch the elastic rope; since the first transmission shaft is connected to the rotating shaft on the fan by a belt, the rotation of the first rotating shaft will drive the fan to rotate. Since the fans are driven by mutually meshing gears, the rotation directions of adjacent fans are different. When the building waste block has not completely passed through the gantry, the fans at 1, 3, 5...2n-1 blow air; thereby blowing air to the lower surface of the building waste block to make it dry quickly; since the building waste block cannot completely pass through the fan when it completely passes through the gantry, when the building waste block completely passes through the gantry, the two rollers in the gantry lose the restriction of the building waste block, and the stretched elastic rope will pull the first transmission shafts on both sides to rotate in the opposite direction, and at this time, the fans at 2, 4, 6...2n blow air; thereby ensuring that the lower surface of the building waste block can be completely dried, effectively preventing the building waste block from sticking to the first conveyor belt.

[0017] As a further solution of the present invention, a shovel plate is elastically and slidably connected under the second scraper plate, and a sliding rod that penetrates the plug plate is slidably connected inside the second scraper plate, and the sliding rod is hinged to a hinge point of the hinge frame, and the hinge frame is a parallelogram frame composed of four mutually hinged rods, and the hinge point of the hinge frame close to the gear side is rotatably connected to the mounting frame; except for the two outermost gears connected to the belt, two pressure shafts are fixedly and symmetrically arranged on the lower surfaces of the remaining gears; hinge frames are arranged between the remaining gears; when working: when the second scraper plate scrapes the dust on the roller shaft between the lower pull rods, the dust contaminated with glue will adhere to the second scraper plate, and long-term accumulation will cause the working efficiency of the second scraper plate to decrease, and eventually the second scraper plate may completely lose its working ability, so it is hoped that the glue-dust mixture attached to the second scraper plate can be cleaned up; while the rotation of the gear drives the fan to dry the building waste block, the pressure shaft under the gear will also rotate synchronously with the gear, because the rotation directions of adjacent meshing gears are opposite; and except for the two outermost gears The gears are fixedly connected with the pressure shaft, and articulated frames are arranged between the other adjacent gears, so the rotation of the other adjacent gears will drive the pressure shaft to squeeze the two articulated rods of the articulated frame. Since the intersection point of the articulated frame close to one side of the gear is rotatably connected to the mounting frame, when the pressure shaft squeezes the two articulated rods of the articulated frame, it will drive the articulated point on the articulated frame away from the mounting frame to move. Since the intersection point of the articulated frame away from the mounting frame is hinged with the sliding rod, the articulated frame will drive the sliding rod to slide in the second scraper plate under the extrusion of the pressure shaft, and because the sliding rod is slidably connected to the shovel plate elastically slidably connected to the second scraper plate, the movement of the sliding rod will drive the shovel plate to slide synchronously; when the pressure shaft is separated from the articulated frame, since the shovel plate is elastically slidably connected to the bottom surface of the second scraper plate, the articulated frame will also reset with the shovel plate; in the process of the gear continuously driving the pressure shaft to rotate, the shovel plate is driven to reciprocate, and the lower surface of the second scraper plate is cleaned of dust and glue mixture, so that the second scraper plate can always be kept clean, and the dust on the roller shaft can be effectively cleaned.

[0018] As a further solution of the present invention, a flywheel is rotatably connected above the first transmission shaft, an incompletely rough surface is provided on the periphery of the flywheel, a sliding frame elastically slidably connected to the gantry is arranged on the periphery of the flywheel, the inner surface of the inner side of the sliding frame is a rough surface, the sliding frame is slidably connected to a scraper frame, and a cleaning plate is fixedly connected to the scraper frame; in addition, a third limiting groove is provided on the support plate, the third limiting groove includes a third process groove and a third return groove, and the scraper frame is slidably arranged in the third limiting groove through a third sliding column fixedly connected thereto; during operation: when the first scraper plate scrapes off the dust on the roller shaft between the upper pull rods, the dust contaminated with glue will adhere to the first scraper plate, and long-term accumulation will cause the working efficiency of the first scraper plate to decrease, and eventually may cause the first scraper plate to completely lose its working ability, so it is hoped that the glue-dust mixture attached to the first scraper plate can be cleaned up: when the construction waste block enters the gantry, the first transmission shafts on both sides will rotate under the drive of the construction waste block, the rotation of the first transmission shaft will drive the flywheel to rotate synchronously, the rotation of the flywheel will drive the sliding frame to move in the direction away from the first transmission shaft, and the sliding frame will The third sliding column is moved to the right end of the third process slot, and the cleaning plate is just in contact with the first scraper plate, and the rough surface of the flywheel is separated from the rough surface of the sliding column. Since the sliding column is elastically slidably connected to the gantry, the sliding column can slide along the third process slot when the sliding column moves in the direction away from the first transmission shaft. The frame will elastically reset after losing the restriction of the flywheel, pulling the scraper frame to move in the opposite direction. The reverse movement of the scraper frame will drive the cleaning plate to move synchronously. Since the sliding column moves into the third return groove at this time, it will move along the third return groove during the reverse movement of the scraper frame until it returns to its initial position. In addition, the flywheel does not rotate when the first transmission shaft reverses. The reciprocating motion driven by the flywheel can remove the dust and glue mixture on the first scraper plate, thereby enabling the first scraper plate to always remain clean and effectively remove dust on the roller shaft.

[0019] As a further solution of the present invention, the method used by the system is as follows:

[0020] Step 1: Compress the construction waste into blocks and transport them to the second conveyor belt;

[0021] Step 2: Apply glue to the six sides of the construction waste block using a roller;

[0022] Step 3: Air-dry the lower surface of the construction waste block to prevent it from sticking to the first conveyor belt;

[0023] Step 4: The construction waste blocks move to the next process along the first conveyor belt.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention can apply glue to the two side surfaces of the construction waste block by means of two rollers arranged in the gantry; the upper pull rod and the lower pull rod are staggered and rotated respectively, so that the upper pull rod and the lower pull rod move along the second limit groove and the first limit groove respectively, so that the upper pull rod and the lower pull rod can compensate for the distance between the roller and the construction waste block when applying glue to the construction waste block, so that the surface of the construction waste block close to the first conveyor belt and the surface away from the conveyor belt during the movement can be completely covered, so that the construction waste block can be completely (that is, the six surfaces can be stably and reliably coated with glue) in a simple transmission state (which can ensure that the construction waste block will not become loose due to transportation), thereby ensuring that the construction waste block can be stably transported.

[0026] The present invention can clean the dust on each roller shaft by means of the third scraper plate, the first scraper plate and the second scraper plate fixedly connected to the gantry; thereby ensuring that the contact surface of the roller shaft with the construction waste block is always kept clean, thereby ensuring that the construction waste block will not be missed from coating, and also ensuring that the system can ensure efficient and complete coating of glue on the six surfaces of the construction waste block during the movement of the construction waste block without stopping the machine to replace the roller shaft, thereby improving the working efficiency of the system.

[0027] The present invention can drive the first transmission shaft to rotate through the construction waste blocks, and then drive the gears to rotate through the belt, so as to drive the fan to rotate, and air-dry the bottom surface of the construction waste blocks. At the same time, after the construction waste blocks have completely passed through the gantry, the force stored in the elastic rope can be used to drive the fan to rotate to air-dry the construction waste blocks that are about to pass through the fan, thereby ensuring that the lower surface of the construction waste blocks can be completely dried, and effectively preventing the construction waste blocks from sticking to the first conveyor belt.

DETAILED DESCRIPTION

[0047] 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.

[0048] See also Figure 1-16 , the present invention provides a technical solution:

[0049] A garbage joint extrusion harmless treatment system comprises: a support device 1, a first conveyor belt 2, a second conveyor belt 2-1 and a gantry 3, wherein the first conveyor belt 2 and the second conveyor belt 2-1 are both arranged in the support device 1, and there is a gap between the first conveyor belt 2 and the second conveyor belt 2-1, and the characteristic is that the gantry 3 is installed on the support device 1 near one end of the second conveyor belt 2-1, a first transmission shaft 11 is rotatably connected inside the gantry 3, a roller shaft 10 is fixedly connected outside the first transmission shaft 11, a first rotating arm 8-2 is rotatably connected above the gantry 3, an upper pull rod 8 is slidably connected to the first rotating arm 8-2, and the first rotating arm 8-2 is also connected to the upper pull rod 8 through a spring 29; one end of a second rotating arm 9-2 is rotatably connected below the gantry 3, the other end of the second rotating arm 9-2 is connected to a lower pull rod 9, and the second rotating arm 9-2 is also connected to the lower pull rod 9 through a spring 29, and in addition, torsion springs are arranged between the first rotating arm 8-2, the second rotating arm 9-2 and the gantry 3;

[0050] The upper pull rod 8 and the lower pull rod 9 are symmetrically provided with a second limit plate 6 and a first limit plate 4 fixedly connected to the gantry 3 on the outside; the first limit plate 4 and the second limit plate 6 are respectively provided with a first limit groove 5 and a second limit groove 7; the first limit groove 5 is composed of a first process groove 5-1, a first stretching groove 5-2 and a first return groove 5-3, wherein the center of the first process groove 5-1 overlaps with the center of the rotation track of the second rotating arm 9-2; the second limit groove 7 is composed of a second process groove 7-1, a second stretching groove 7-3 and a second return groove 7-2, wherein the center of the second process groove 7-1 overlaps with the center of the rotation track of the first rotating arm 8-2; the upper pull rod 8 is slidably connected to the second limit groove 7 through the first sliding column 8-1 fixedly connected thereto; the lower pull rod 9 is slidably connected to the first limit groove 5 through the second sliding column fixedly connected thereto; roller shafts 10 are rotatably connected between the two upper pull rods 8 and the two lower pull rods 9. .

[0051] When the present invention is used: first, the compressed building waste blocks are transported to the second conveyor belt 2-1, and then the second conveyor belt 2-1 drives the building waste blocks to move and pass through the gantry 3; when the building waste blocks pass through the gantry 3, first, the building waste blocks will contact the two rollers 10 on the side of the gantry 3, and the rollers 10 will roll under the drive of the building waste blocks, so as to apply glue to the two sides of the building waste blocks; the building waste blocks move further, and the side close to the first conveyor belt 2 will contact the rollers 10 between the lower pull rods 9 ( Figure 1 , 3 As shown in FIG. 1 ), the construction waste block pushes the roller shaft 10 to drive the roller shaft 10 to rotate around the second rotating arm 9-2 and the gantry 3 ( Figure 4The roller shaft 10 between the lower pull rod 9 rotates synchronously with the second rotating arm 9-2, and the surface of the building waste block facing the first conveyor belt 2 is coated with glue; since the lower pull rod 9 is connected to the second rotating arm 9-2 by a spring 29 ( Figure 5 As shown), the lower pull rod 9 is slidably connected to the first limiting groove 5 on the first limiting plate 4 through the second sliding column 9-1 fixedly connected thereto ( Figure 4 As shown in the figure, during the downward rotation of the lower pull rod 9, the second slide column 9-1 slides along the first process groove 5-1, and finally passes over the reversing wedge T of the first process groove 5-1 and enters the first stretching groove 5-2. Since the center of the first process groove 5-1 coincides with point P, the distance between the first slide column and point P remains unchanged during the downward rotation of the lower pull rod 9, so the lower pull rod 9 will not be stretched during the downward rotation; when the second slide column 9-1 moves to the end of the first process groove 5-1, that is, the connection between the first process groove 5-1 and the first stretching groove 5-2, the roller shaft 10 between the lower pull rod 9 contacts the bottom surface of the building waste block and applies glue to the bottom surface of the building waste block. When the lower surface of the construction waste block is separated from the roller shaft 10 between the lower pull rods 9, the first rotating arm 8-2 will be reset under the action of the torsion spring, and the first rotating arm 8-2 will drive the lower pull rod 9 to rotate in the opposite direction. Since the second sliding column 9-1 fixedly connected to the lower pull rod 9 is located in the first stretching groove 5-2 at this time, when the first rotating arm 8-2 drives the lower pull rod 9 to reset, the second sliding column 9-1 will slide along the first stretching groove 5-2, thereby driving the lower pull rod 9 to stretch, thereby compensating for the displacement of the construction waste block moving toward the first conveyor belt 2 , and at the same time compensates for the lateral distance difference between the lower pull rod 9 and the building waste block when it rotates around point P; in addition, in the process of the second slide column 9-1 moving along the first stretching groove 5-2, the speed of the lower pull rod 9 moving away from the first rotating arm 8-2 will gradually increase with the movement of the second slide column 9-1 in the first stretching groove 5-2, that is, as the elongation speed of the lower pull rod 9 gradually increases, thereby compensating for the displacement of the lateral distance between the lower pull rod 9 and the building waste block when it rotates around point P; thereby being able to remotely control the building waste block The first conveyor belt 2 is coated with glue; then the second slide post 9-1 moves into the first return groove 5-3, and the roller shaft 10 between the lower pull rod 9 is completely separated from the clamped garbage block. At this time, the second slide post 9-1 moves to the end of the first stretching groove 5-2, that is, the connection between the first stretching groove 5-2 and the first return groove 5-3; then the lower pull rod 9 will be reset under the action of the spring 29, that is, the lower pull rod 9 is reset by moving along the first return groove 5-3 toward the direction of the first rotating arm 8-2 through the second slide post 9-1 fixedly connected thereto.

[0052] Similarly, the upper pull rod 8 above will also perform similar movements with the lower pull rod 9, so as to complete the glue coating of the surface of the construction waste block close to the first conveyor belt 2, the surface away from the first conveyor belt 2 and the upper surface of the construction waste block; it should be noted that (such as Figure 4 As shown), in the initial state, there is a lateral distance between the roller shafts 10 on the upper pull rod 8 and the lower pull rod 9, so this lateral distance can ensure that there is a certain time difference when the upper pull rod 8 and the lower pull rod 9 work, thereby avoiding interference between the upper pull rod 8 and the lower pull rod 9 when they make return motion in the corresponding second return groove 7-3 and the first return groove 5-3.

[0053] In addition, since the upper rod 8 is longer than the lower rod 9, and the upper rod 8 and the lower rod 9 are initially staggered, the lower rod 9 is closer to the gantry 3 than the upper rod 8 ( Figure 4 As shown in the figure, the rotation of the lower pull rod 9 will not interfere with the upper pull rod 8, so the lower pull rod 9 will be pushed and rotated by the construction waste block relative to the upper pull rod 8 first, and then reset; and the upper pull rod 8 and the lower pull rod 9 are staggered and rotated separately, so that the surface of the construction waste block close to the first conveyor belt 2 and the surface away from the conveyor belt can be completely covered (when the two rollers 10 located on a vertical line apply glue to the surface parallel to the rollers 10 by rotating around a point, a gap will be generated between the two rollers 10 on the coated surface, and the entire surface cannot be completely coated, while the staggered distribution will completely cover the coated surface), ensuring that no glue is missed;

[0054] After the construction waste blocks are completely coated with glue, they will move to the next process along the first conveyor belt 2.

[0055] As a further solution of the present invention, a second scraper plate 18 ( Figure 3 , 6 As shown in FIG. 1 ), the second scraper plate 18 is provided with an inclination angle downward from the gear 16 to the second conveyor belt 2-1, and the first scraper plate 13 ( Fig.13 As shown in FIG. 1 ), the first scraper plate 13 is also provided with a certain inclination angle; the third scraper plate 27 ( Fig. 9 , 10As shown); during operation: since there is still a large amount of dust on the surface of the extruded construction waste blocks that is easy to fall off, when the roller 10 is coating the construction waste blocks with glue, it is inevitable that the dust on the construction waste blocks will be contaminated onto the roller 10, which may cause the circumference of the roller 10 to be covered with dust and unable to continue to coat the construction waste blocks with glue. Replacing the roller 10 in the middle requires suspending the processing line, which will also reduce the efficiency of the system in coating the construction waste blocks with glue. Therefore, it is hoped that the roller 10 can remove the contaminated dust during the process of coating the construction waste blocks with glue, so as to ensure that the system can efficiently coat the six surfaces of the construction waste with glue during the movement of the construction waste blocks; the two rollers 10 rotatably arranged in the gantry 3 will drive the two rollers 10 to rotate counterclockwise and clockwise respectively through friction when the construction waste blocks pass by. Since the gantry 3 is fixedly connected with a third scraper plate 27, The dust on the two rollers 10 in the gantry 3 will be scraped off by the third scraper plate 27; similarly, after the rollers 10 between the upper pull rods 8 are pushed upward by the construction waste blocks, the rollers 10 between the upper pull rods 8 will be tangent to the first scraper plate 13. Since the rollers 10 will be driven to rotate by the friction force generated between the construction waste blocks and the rollers 10, the first scraper plate 13 will scrape off the dust on the rollers 10 between the upper pull rods 8; similarly, the second scraper fixedly connected to the support device 1 through the connecting column 30 can also clean the dust on the rollers 10 between the lower pull rods 9; thereby ensuring that the contact surface of the rollers 10 with the construction waste blocks is always kept clean, thereby ensuring that the construction waste blocks will not be missed from coating, and also ensuring that the system can ensure efficient and complete coating of the six surfaces of the construction waste blocks during the movement of the construction waste blocks without stopping the machine to replace the rollers 10, thereby improving the working efficiency of the system.

[0056] As a further solution of the present invention, a mounting frame 15 is fixedly connected to the support device 1 at one end of the first conveyor belt 2 close to the second conveyor belt 2-1. Figure 3 As shown, the mounting frame 15 is rotatably connected to a plurality of gears 16 via a rotating shaft, and the plurality of gears 16 mesh with each other; in addition, identical fans 19 are fixedly connected to the rotating shafts above the gears 16, and the number of the gears 16 is an even number. The rotating shafts above the two outermost gears 16 are also connected to the first transmission shaft 11 via a belt 17; the two first rotating shafts rotatably connected to the gantry 3 are connected via an elastic rope 20 ( Figure 6 , 8As shown); during operation: since the glue on the lower surface of the construction waste block cannot dry quickly after the lower part of the construction waste block passes through the roller 10 for glue coating, when the construction waste block enters the first conveyor belt 2, the glue on the lower surface of the construction waste block will be smeared on the first conveyor belt 2, causing the construction waste block to adhere to the first conveyor belt 2, so it is hoped that the contact surface of the construction waste block with the first conveyor belt 2 can dry quickly; when the construction waste block passes through the gantry 3, the friction between the construction waste block and the two rollers 10 on the inner side of the gantry 3 will drive the two rollers 10 to rotate clockwise and counterclockwise respectively, and the two rollers 10 will also stretch the elastic rope 20; since the first transmission shaft 11 is connected to the rotating shaft on the fan 19 by the belt 17, the rotation of the first transmission shaft 11 will drive the fan 19 to rotate. Since the fans 19 are driven by the mutually meshing gears 16, the rotation directions of adjacent fans 19 are different. When the construction waste block has not completely passed through the gantry 3 (such as Figure 3 As shown in the figure, the fans 19 at 1, 3, 5...2n-1 blow air; thereby blowing air on the lower surface of the construction waste block to make it dry quickly; because the construction waste block cannot completely pass through the fan 19 when it completely passes through the gantry 3, when the construction waste block completely passes through the gantry 3, the two rollers 10 in the gantry 3 lose the restriction of the construction waste block, and the stretched elastic ropes 20 will pull the first transmission shafts 11 on both sides to rotate in the opposite direction. At this time, the fans 19 at 2, 4, 6...2n blow air; thereby ensuring that the lower surface of the construction waste block can be completely dried, effectively preventing the construction waste block from sticking to the first conveyor belt 2.

[0057] As a further solution of the present invention, a shovel plate 22 is elastically slidably connected below the second scraper plate 18, and a sliding rod 23 ( Figure 7 As shown, the sliding rod 23 is hinged to a hinge point of the hinge frame 24, and the hinge frame is a parallelogram frame composed of four mutually hinged rods ( Figure 6 , 8As shown in the figure, the hinged frame 24 is rotatably connected to the mounting frame 15 at the hinged point near the gear 16; except for the two outermost gears 16 connected to the belt 17, two pressing shafts 21 are fixedly and symmetrically arranged on the lower surface of the remaining gears 16; the hinged frame 24 is arranged between the remaining gears 16; when working: when the second scraper plate 18 scrapes the dust on the roller shaft 10 between the lower pull rods 9, the dust contaminated with glue will adhere to the second scraper plate 18, and the long-term accumulation will cause the working efficiency of the second scraper plate 18 to decrease, which may eventually lead to The second scraper 18 completely loses its working ability, so it is hoped that the glue dust mixture attached to the second scraper 18 can be cleaned up; the rotation of the gear 16 drives the fan 19 to air-dry the building waste block, and the pressure shaft 21 under the gear 16 will also rotate synchronously with the gear 16. Since the rotation directions of adjacent meshing gears 16 are opposite, and except for the two outermost gears 16, the pressure shaft 21 is fixedly connected, and the remaining adjacent gears 16 are provided with an articulated frame 24, so the rotation of the remaining adjacent gears 16 will drive the pressure shaft 2 The two hinged rods of the hinged frame 24 are squeezed by the pressing shaft 21. Since the intersection of the hinged frame 24 near the gear 16 is rotatably connected to the mounting frame 15, the pressing shaft 21 squeezes the two hinged rods of the hinged frame 24, which drives the hinged point of the hinged frame 24 away from the mounting frame 15 to move. Since the intersection of the hinged frame 24 away from the mounting frame 15 is hinged to the sliding rod 23, the hinged frame 24 drives the sliding rod 23 to slide in the second scraper plate 18 under the squeezing of the pressing shaft 21. Since the sliding rod 23 is elastically connected to the second scraper plate 18, the sliding rod 23 is elastically connected to the second scraper plate 18. The shovel plate 22 on the scraper plate 18, so the movement of the sliding rod 23 will drive the shovel plate 22 to slide synchronously; when the pressure shaft 21 is separated from the articulated frame 24, since the shovel plate 22 is elastically slidably connected to the bottom surface of the second scraper plate 18, the articulated frame 24 will also be reset together with the shovel plate 22; in the process of the gear 16 continuously driving the pressure shaft 21 to rotate, the shovel plate 22 is driven to reciprocate, and the dust and glue mixture are removed from the lower surface of the second scraper plate 18, so that the second scraper plate 18 can always be kept clean, and the dust on the roller 10 can be effectively removed.

[0058] As a further solution of the present invention, a flywheel 28 is rotatably connected to the upper portion of the first transmission shaft 11, and an incompletely rough surface ( Fig.14 As shown, the flywheel 28 is provided with a sliding frame 12 ( Fig.13 As shown, the inner surface of the inner side of the sliding frame 12 is a rough surface, the sliding frame 12 is slidably connected to the scraper frame 14, and the scraper frame 14 is fixedly connected to the cleaning plate 14-1; in addition, the support plate 25 is provided with a third limiting groove 26 ( Fig.12As shown in the figure, the third limiting groove 26 includes a third process groove 26-2 and a third return groove 26-1, and the scraper frame 14 is slidably arranged in the third limiting groove 26 through the third sliding column 25-1 fixedly connected thereto; during operation: when the first scraper plate 13 scrapes the dust on the roller shaft 10 between the upper pull rod 8, the dust contaminated with glue will adhere to the first scraper plate 13, and long-term accumulation will cause the working efficiency of the first scraper plate 13 to decrease, and eventually may cause the first scraper plate 13 to completely lose its working ability, so it is hoped that the glue-dust mixture attached to the first scraper plate 13 can be cleaned up: when the construction waste block enters the gantry 3, the first transmission shafts 11 on both sides will rotate under the drive of the construction waste block, and the rotation of the first transmission shaft 11 will drive the flywheel 28 to rotate synchronously, and the rotation of the flywheel 28 will drive the sliding frame 12 to move in the direction away from the first transmission shaft 11, and the sliding frame 12 will drive the scraper frame 14 slidably connected thereto to move synchronously; since the scraper frame 14 passes The third sliding post 25-1 is slidably connected to the third limiting groove 26 by the third sliding post 25-1 fixedly connected thereto, so the scraper frame 14 will slide along the third process groove 26-2 during the movement of the sliding frame 12 in the direction away from the first transmission shaft 11, thereby driving the scraper frame 14 to drive the cleaning plate 14-1 fixedly connected to the scraper frame 14 to move synchronously. When the third sliding post 25-1 moves to the rightmost end of the third process groove 26-2, the cleaning plate 14-1 just fits with the first scraper plate 13, and the rough surface of the flywheel 28 is separated from the rough surface of the sliding frame 12; since the sliding frame 12 is elastically slidably connected to the gantry 3, the sliding frame 12 will elastically reset after losing the restriction of the flywheel 28, pulling the scraper frame 14 to move in the opposite direction, and the reverse movement of the scraper frame 14 will drive the cleaning plate 14-1 to move synchronously. Since the sliding post moves into the third return groove 26-1 at this time, it will move along the third return groove 26-1 during the reverse movement of the scraper frame 14 until it returns to its initial position ( Fig.12 As shown), in addition, when the first transmission shaft 11 is reversed, the flywheel 28 does not rotate; driven by the flywheel 28, the reciprocating motion is achieved to remove the dust and glue mixture on the first scraper plate 13, so that the first scraper plate 13 can always be kept clean and the dust on the roller 10 can be effectively removed.

[0059] As a further solution of the present invention, the method used by the system is as follows:

[0060] Step 1: compress the construction waste into blocks and transport them to the second conveyor belt 2-1;

[0061] Step 2: Apply glue to the six sides of the construction waste block through the roller 10;

[0062] Step 3: Air-dry the lower surface of the construction waste block to prevent it from sticking to the first conveyor belt 2;

[0063] Step 4: The construction waste blocks move to the next process along the first conveyor belt 2.

[0064] Working principle: First, the compressed construction waste blocks are transported to the second conveyor belt 2-1, and then the second conveyor belt 2-1 drives the construction waste blocks to move and pass through the gantry 3; when the construction waste blocks pass through the gantry 3, the construction waste blocks first contact with the two rollers 10 in the gantry 3, and the rollers 10 roll under the drive of the construction waste blocks, thereby applying glue to the two sides of the construction waste blocks; the construction waste blocks move further, and the side close to the first conveyor belt 2 contacts with the rollers 10 between the lower pull rods 9 ( Figure 1 , 3 As shown in FIG. 1 ), the construction waste block pushes the roller shaft 10 to drive the roller shaft 10 to rotate around the second rotating arm 9-2 and the gantry 3 ( Figure 4 The roller shaft 10 between the lower pull rod 9 rotates synchronously with the second rotating arm 9-2, and the surface of the building waste block close to the first conveyor belt 2 is coated with glue; since the lower pull rod 9 is connected to the second rotating arm 9-2 by a spring 29 ( Figure 5 As shown), the lower pull rod 9 is slidably connected to the first limiting groove 5 on the first limiting plate 4 through the second sliding column 9-1 fixedly connected thereto ( Figure 4As shown in the figure, during the downward rotation of the lower pull rod 9, the second slide column 9-1 slides along the first process groove 5-1, and finally passes over the first process groove 5-1 and enters the first stretching groove 5-2. Since the center of the first process groove 5-1 coincides with point P, the distance between the first slide column and point P remains unchanged during the downward rotation of the lower pull rod 9, so the lower pull rod 9 will not be stretched during the downward rotation; when the second slide column 9-1 moves to the end of the first process groove 5-1, that is, the connection between the first process groove 5-1 and the first stretching groove 5-2, The roller shaft 10 between the lower pull rods 9 contacts the bottom surface of the construction waste block and applies glue to the bottom surface of the construction waste block. When the lower surface of the construction waste block is separated from the roller shaft 10 between the lower pull rods 9, the first rotating arm 8-2 will be reset under the action of the torsion spring, and the first rotating arm 8-2 will drive the lower pull rod 9 to rotate in the opposite direction. Since the second sliding column 9-1 fixedly connected to the lower pull rod 9 is located in the first stretching groove 5-2 at this time, when the first rotating arm 8-2 drives the lower pull rod 9 to reset, the second sliding column 9-1 will slide along the first stretching groove 5-2, thereby driving the lower pull rod 9 The second slide post 9-1 is stretched to compensate for the displacement of the construction waste block toward the first conveyor belt 2, and also compensates for the lateral distance difference between the pull-down rod 9 and the construction waste block when the pull-down rod 9 rotates around the point P; in addition, during the movement of the second slide post 9-1 along the first stretching groove 5-2, the speed of the pull-down rod 9 in the direction away from the first rotating arm 8-2 will gradually increase with the movement of the second slide post 9-1 in the first stretching groove 5-2, that is, the elongation speed of the pull-down rod 9 gradually increases, thereby compensating for the displacement of the lateral distance between the pull-down rod 9 and the construction waste block when the pull-down rod 9 rotates around the point P. ; Then, the side of the building waste block away from the first conveyor belt 2 can be coated with glue; then, the second slide column 9-1 moves into the first return groove 5-3, and the roller shaft 10 between the lower pull rod 9 is completely separated from the clamped waste block. At this time, the second slide column 9-1 moves to the end of the first stretching groove 5-2, that is, the connection between the first stretching groove 5-2 and the first return groove 5-3; then, the lower pull rod 9 will be reset under the action of the spring 29, that is, the lower pull rod 9 is reset by moving along the first return groove 5-3 toward the direction of the first rotating arm 8-2 through the second slide column 9-1 fixedly connected thereto;

[0065] Similarly, the upper pull rod 8 above will also perform similar movements with the lower pull rod 9, so as to complete the glue coating of the surface of the construction waste block close to the first conveyor belt 2, the surface away from the first conveyor belt 2 and the upper surface of the construction waste block; it should be noted that Figure 4 As shown, in the initial state, there is a lateral distance between the roller shafts 10 on the upper pull rod 8 and the lower pull rod 9, so this lateral distance can ensure that there is a certain time difference when the upper pull rod 8 and the lower pull rod 9 work, thereby avoiding interference between the upper pull rod 8 and the lower pull rod 9 when they make return motion in the corresponding second return groove 7-3 and the first return groove 5-3.

[0066] In addition, since the upper rod 8 is longer than the lower rod 9, and the upper rod 8 and the lower rod 9 are initially staggered, the lower rod 9 is closer to the gantry 3 than the upper rod 8 ( Figure 4 As shown in the figure, the rotation of the lower pull rod 9 will not interfere with the upper pull rod 8, so the lower pull rod 9 will be pushed and rotated by the construction waste block relative to the upper pull rod 8 first, and then reset; and the upper pull rod 8 and the lower pull rod 9 are staggered and rotated separately, so that the surface of the construction waste block close to the first conveyor belt 2 and the surface away from the conveyor belt can be completely covered (when the two rollers 10 located on a vertical line apply glue to the surface parallel to the rollers 10 by rotating around a point, a gap will be generated between the two rollers 10 on the coated surface, and the entire surface cannot be completely coated, while the staggered distribution will completely cover the coated surface), ensuring that no glue is missed;

[0067] After the construction waste blocks are completely coated with glue, they will move to the next process along the first conveyor belt 2.
