[0002] With the development of the urbanization process, the construction industry has developed vigorously. At the same time, the amount of construction waste generated is also increasing day by day. Construction waste mainly includes materials such as waste concrete, bricks and tiles, wood, metal and plastic. Among these waste materials, materials with higher utilization rates and values such as wood, metal and plastic are easier to be processed because of the mature recycling industrial chain. However, construction waste such as concrete needs to be pulverized by a corresponding construction waste recycling device and then recycled.

Detailed implementation manners

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings, but the protection scope is not limited by this.

[0017] See Figures 1 to 12, this embodiment provides a construction waste recycling device that facilitates hierarchical processing, including a machine body 1 and a crushing mechanism 2. Crushing mechanisms 2 are arranged on both the left and right sides of the machine body 1. A conveyor belt mechanism 3 is arranged inside the machine body 1. The crushing mechanism 2 above the right side is connected to the crushing mechanism 2 below the left side through the conveyor belt mechanism 3; the construction concrete solid waste crushed by the crushing mechanism 2 above the right side is sent to the crushing mechanism 2 below the left side through the conveyor belt mechanism 3 for secondary crushing.

[0018] The crushing mechanism 2 includes a mounting frame 4, a mounting box 5, a feed sleeve 7, a transmission rod 10, a movable body 11, a motor 12, a fixed seat 13 and an adjustment assembly 21; the bottom of the mounting frame 4 is fixedly installed on the machine body 1, and an opening is provided at the top of the mounting frame 4, and a mounting box 5 is fixed in the opening; the feed sleeve 7 is movably arranged inside the mounting box 5; electric push rods 6 are symmetrically arranged outside the mounting box 5, and the output end of the electric push rod 6 is connected to a horizontal rod 22, and a ball 23 is rotatably arranged at the front end of the rod 22; the electric push rod 6 abuts against the bottom edge of the outer wall of the feed sleeve 7 through the ball 23 at the front end of the rod 22; the electric push rod 6 is used for adjusting the vertical position of the feed sleeve 7. By moving the output end of the electric push rod 6 up and down, the rod 22 can be driven to move up and down, so as to lift or lower the height of the feed sleeve 7 relative to the mounting box 5 through the abutment between the ball 23 and the bottom edge of the outer wall of the feed sleeve 7. A feed hopper cover 71 is installed at the top of the feed sleeve 7, and the construction concrete solid waste can smoothly enter the feed sleeve 7 through the feed hopper cover 71.

[0019] A fixed frame 15 is installed outside the fixed seat 13, and the fixed frame 15 is installed inside the lower part of the mounting box 5; an adjustment assembly 21 is arranged inside the lower part of the fixed seat 13, and the motor 12 is fixedly connected inside the upper part of the fixed seat 13; the output end of the motor 12 is fixedly connected to the lower end of the transmission rod 10, and the top of the transmission rod 10 is fixedly connected to a sliding rod 9, and grooves are symmetrically opened on the outside of the sliding rod 9; connecting rods 8 are symmetrically fixed on the upper part of the inner side of the feed sleeve 7, and bumps are arranged at the adjacent ends of the two connecting rods 8. The bumps of the connecting rods 8 are in concave-convex fit with the grooves on the corresponding sliding rods 9 for synchronous rotation; and the connecting rods 8 are slidably sleeved outside the sliding rods 9 along the vertical direction; when the motor 12 drives the transmission rod 10 to rotate horizontally, the transmission rod 10 drives the sliding rod 9 to rotate horizontally. Due to the concave-convex fit between the bumps of the connecting rods 8 and the grooves on the corresponding sliding rods 9, the sliding rod 9 drives the connecting rods 8 and the feed sleeve 7 to rotate horizontally.

[0020] The outer side of the upper end of the transmission rod 10 has a spherical outer shape structure. The top of the movable body 11 is provided with an opening, and the opening corresponds to the spherical outer shape structure at the upper end of the transmission rod 10. The movable body 11 is circumferentially and movably connected to the outer side of the upper end of the transmission rod 10 through the opening at the top; the movable body 11 has a conical structure, and a cavity is provided inside the movable body 11. A top block 101 is connected to the outer side of the lower section of the transmission rod 10, and one end of the top block 101 away from the transmission rod 10 abuts against the inner side wall of the cavity of the movable body 11; when the transmission rod 10 rotates and synchronously drives the top block 101 to rotate, it abuts against a place on the inner wall of the cavity of the movable body 11, so that the movable body 11 rotates and moves along with the abutment of the top block 101, and the movable body 11 circumferentially moves and tilts on the spherical outer shape structure of the transmission rod 10; the shape of the inner side wall of the lower part of the feeding sleeve 7 is also a conical structure, corresponding to the structure of the movable body 11. A plurality of second hydraulic cavities 214 are circumferentially and equally angled on the conical surface at the top of the movable body 11, and a plurality of second hydraulic cavities 214 are respectively connected with oil nozzles; a breaking block 215 is hermetically and slidably arranged in the second hydraulic cavity 214. Through the mutual action and extrusion between the breaking block 215 and the inner side wall of the lower part of the feeding sleeve 7, it is used to extrude and crush construction waste.

[0021] The adjusting assembly 21 includes a first hydraulic cavity 211, a second electric push rod 212 and a plug body 213; the first hydraulic cavity 211 is opened on the inner side of the lower part of the fixed seat 13, and the second electric push rod 212 is arranged at the inner bottom of the first hydraulic cavity 211; the top of the second electric push rod 212 is connected with the plug body 213, and the plug body 213 is hermetically and slidably connected with the inner wall of the first hydraulic cavity 211, and hydraulic fluid is poured between the plug body 213 and the inner wall of the first hydraulic cavity 211; a pressure sensor is arranged at the upper end of the plug body 213, the first hydraulic cavity 211 is connected with a plurality of oil nozzles, and the oil nozzles on the first hydraulic cavity 211 are connected with the oil nozzles on the second hydraulic cavity 214 one by one through hoses.

[0022] When the stones with larger size and higher hardness in the construction concrete solid waste are extruded, the pressure received by the breaking block 215 at the extrusion place of the stones will be greater than the pressure of extruding the concrete waste in the solid waste. The breaking block 215 transmits the pressure into the first hydraulic cavity 211 through the hydraulic fluid in the second hydraulic cavity 214. At this time, the pressure sensor on the plug body 213 detects the change of the pressure value, and the regulating system of the controller turns on the second electric push rod 212 to adjust the position of the plug body 213 downward, so that the first hydraulic cavity 211 and the second hydraulic cavity 214 are adjusted to the pressure value corresponding to the concrete crushing. In this process, when the plug body 213 moves downward, the breaking block 215 at the extrusion place of the stones moves inward in the second hydraulic cavity 214, so that the space between the breaking block 215 corresponding to the larger stones and the feeding sleeve 7 increases, and then the stones fall from this place, and together with the crushed concrete, they fall into the lower screening mechanism after the circumferential inclination position of the movable body 11 changes, completing the peeling of the harder stones in the concrete.

[0023] A screening mechanism is arranged below the crushing mechanism 2; the screening mechanism includes a material baffle 16, a fixed rod 17, a movable rod 18, a screening plate 19 and a mounting rod 20; the material baffle 16 is fixed to the bottom of the movable body 11, a fixed rod 17 is connected to the lower part outside the material baffle 16, and the lower end of the fixed rod 17 is connected to a movable rod 18; the side wall of the screening plate 19 is provided with an opening, one end of the movable rod 18 movably passes through the opening on the screening plate 19, and two convex pieces are arranged on the outside of one end of the movable rod 18, one of the convex pieces is located inside the screening plate 19, and the other convex piece is located outside the screening plate 19, and the movable rod 18 is limited by the two convex pieces; convex columns are symmetrically arranged on both sides of the bottom of the screening plate 19, and the screening plate 19 is rotatably connected to the middle of the mounting rod 20 through the convex columns on both sides of the bottom, and both ends of the mounting rod 20 are fixed to the mounting frame 4. A vibrator is installed on one side of the screening plate 19, and the screening plate 19 below the crushing mechanism 2 on the right side is designed to be inclined to the left, and the discharge port of the screening plate 19 is located above the conveyor belt mechanism 3.

[0024] When the peeled stones and crushed concrete fall into the screening plate 19, the vibrator on the screening plate 19 causes the screening plate 19 to vibrate at a high frequency. At the same time, the circumferentially inclined moving movable body 11 drives the material baffle 16 and the fixed rod 17 to move synchronously. The fixed rod 17 is movably connected to the screening plate 19 through the movable rod 18, so that when the movable rod 18 moves, it drives the screening plate 19 to swing up and down around the mounting rod 20, improving the screening effect of the crushed concrete and peeled stones in the screening plate 19. With the high-frequency vibration of the vibrator on the screening plate 19, the crushed concrete in the screening plate 19 gradually falls through the sieve holes of the screening plate 19 into the stockpiling area 24 below, while the unbroken large pieces of concrete and stones on the screening plate 19 fall onto the conveyor belt mechanism 3 that feeds the crushing mechanism 2 on the lower left side for secondary crushing and stone peeling. The stockpiling area 24 and the conveyor belt mechanism 3 are independent mechanisms, and a conveyor belt is also arranged on the stockpiling area 24, and the conveying direction of the stockpiling area 24 is opposite to the conveying direction of the conveyor belt mechanism 3.

[0025] The working principle of a construction waste recycling device that facilitates layered treatment proposed in this embodiment is as follows: Before the construction concrete solid waste is crushed, first, the operator turns on the vibrator and the second electric push rod 212 on the screening plate 19 in the crushing mechanism 2 on the right side. After the second electric push rod 212 is turned on, it drives the plug body 213 to move upward, so that the oil liquid in the first oil pressure cavity 211 flows into the second oil pressure cavity 214 through the hose. The breaking block 215 moves to the maximum position as the second oil pressure cavity 214 increases. At this time, the second electric push rod 212 continues to move upward, and the pressure sensor on the plug body 213 detects that the pressure in the first oil pressure cavity 211 and the second oil pressure cavity 214 gradually increases. When the pressure is adjusted to the appropriate crushing pressure for the concrete, the second electric push rod 212 is turned off.

[0026] Then, the controller turns on the electric push rod 6, and according to the size of the construction concrete solid waste to be crushed, the electric push rod 6 is used to adjust the position of the feed sleeve 7 in the installation box 5, so that a suitable gap is reached between the inner wall below the feed sleeve 7 and the broken wall block 215 outside the movable body 11, and then the controller turns on the motor 12, and the motor 12 drives the transmission rod 10 and the sliding rod 9 to rotate synchronously, and through the concave-convex fit between the sliding rod 9 and the connecting rod 8, the connecting rod 8 and the feed sleeve 7 are driven to rotate synchronously, and then the construction concrete waste is evenly fed into the feed hopper cover 71 through the external waste conveying mechanism.

[0027] When the construction concrete solid waste enters the feed sleeve 7, as the feed sleeve 7 rotates, the construction concrete solid waste gradually enters between the feed sleeve 7 and the movable body 11. When the transmission rod 10 rotates, it synchronously drives the top block 101 to rotate while contacting the movable body 11, so that the movable body 11 is contacted by the rotating top block 101, causing the movable body 11 to move circumferentially and tilt on the spherical shape structure above the transmission rod 10; at this time, the gap between the breaking block 215 at the upper end of the movable body 11 in the tilting direction and the feed sleeve 7 is reduced, thereby squeezing and crushing the construction concrete solid waste.

[0028] When encountering large and hard stones in the solid waste of construction concrete, the pressure exerted on the wall-breaking block 215 at the stone-extrusion site will be greater than the pressure when the concrete waste is crushed. The wall-breaking block 215 transmits the pressure to the oil-pressure chamber 1 211 through the oil in the oil-pressure chamber 214. At this time, the pressure sensor on the plug body 213 detects the pressure value change and turns on the electric push rod 212 through the adjustment system of the controller to quickly adjust the position of the plug body 213 downward, so that the oil-pressure chamber 1 211 and the oil-pressure chamber 2 214 are quickly adjusted to the pressure value corresponding to the concrete crushing; in this process, when the plug body 213 moves downward, the wall-breaking block 215 at the stone-extrusion site moves toward the inside of the oil-pressure chamber 214, making the space there larger, and the larger stones fall here and fall onto the screening plate 19 together with the crushed concrete, completing the stripping of the harder stones in the concrete.

[0029] After the stripped stones and crushed concrete fall into the screening tray 19, the vibrator on the screening tray 19 causes the screening tray 19 to vibrate at a high frequency. At the same time, the movable body 11 drives the material retaining cover 16 and the fixed rod 17 to move synchronously. The fixed rod 17 is movably connected to the screening tray 19 through the movable rod 18, so that when the movable rod 18 moves, it drives the screening tray 19 to swing up and down around the mounting rod 20. Combining with the high-frequency vibration of the vibrator on the screening tray 19, the crushed concrete in the screening tray 19 gradually falls through the screening holes of the screening tray 19 into the stacking area 24 below. At the same time, the insufficiently crushed concrete and the stripped stones on the screening tray 19 fall into the conveyor belt mechanism 3 from the discharge port on the left side of the screening tray 19 and are sent into the crushing mechanism 2 on the left side through the conveyor belt mechanism 3. The crushing parameters of the crushing mechanism 2 on the left side are adjusted to complete secondary crushing.

[0030] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are limited thereto. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the premise of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
