[0035] The outer side of the upper end of the transmission rod 10 is in a spherical shape, the top of the movable body 11 is provided with a hole corresponding to the spherical shape of the upper end of the transmission rod 10, and the movable body 11 is connected to the outer side of the upper end of the transmission rod 10 through the hole in the top in a circumferential direction. The movable body 11 is in a conical structure, and the movable body 11 is internally provided with a cavity. The lower end of the transmission rod 10 is connected to a top block 101, and the end of the top block 101 away from the transmission rod 10 is in contact with 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, the movable body 11 is moved and rotated by the contact of the top block 101 with the inner wall of the cavity of the movable body 11, and the movable body 11 moves and tilts in a circumferential direction on the spherical structure of the transmission rod 10. The inner side wall below the feeding sleeve 7 is also in a conical structure and corresponds to the structure of the movable body 11. A plurality of oil pressure cavities 214 are provided on the conical surface of the top of the movable body 11 in a circumferential direction at equal angles, and the oil pressure cavities 214 are respectively connected to oil nozzles. A wall breaking block 215 is movably arranged in the oil pressure cavities 214. The wall breaking block 215 is extruded by the interaction with the inner side wall below the feeding sleeve 7, and is used for extruding and crushing the construction waste.

[0036] The adjusting assembly 21 comprises an oil pressure cavity 211, an electric push rod 212 and a plug 213. The oil pressure cavity 211 is arranged on the inner side below the fixed seat 13, and the electric push rod 212 is arranged on the inner bottom of the oil pressure cavity 211. The top of the electric push rod 212 is connected to the plug 213, and the plug 213 is movably connected to the inner wall of the oil pressure cavity 211. The plug 213 and the oil pressure cavity 211 are filled with oil. The upper end of the plug 213 is provided with a pressure sensor, and the oil pressure cavity 211 is connected to a plurality of oil nozzles. The oil nozzles on the oil pressure cavity 211 are connected to the oil nozzles on the oil pressure cavity 214 through a hose in a one-to-one correspondence.

[0037] When the stone with a large size and high hardness in the construction concrete solid waste is extruded, the pressure on the wall breaking block 215 at the extruded stone is greater than the pressure on the wall breaking block 215 at the extruded concrete waste in the solid waste. The pressure is transmitted from the wall breaking block 215 in the oil pressure cavity 214 to the oil pressure cavity 211 through the oil. At this time, the pressure sensor on the plug 213 detects the change of the pressure value, and the adjusting system of the controller is opened to adjust the position of the plug 213 downward, so that the oil pressure cavity 211 and the oil pressure cavity 214 are adjusted to the pressure value corresponding to the crushing of the concrete. In this process, when the plug 213 moves downward, the wall breaking block 215 at the extruded stone moves inward in the oil pressure cavity 214, so that the space between the wall breaking block 215 corresponding to the large stone and the feeding sleeve 7 is increased, and then the stone falls from the space, and is crushed together with the concrete after the position of the movable body 11 changes, and falls into the screening mechanism below, so as to complete the stripping of the hard stone in the concrete.

[0038] A screening mechanism 2 is arranged below the crushing mechanism 2; the screening mechanism 2 comprises a material blocking cover 16, a fixed rod 17, a movable rod 18, a screening disc 19 and a mounting rod 20; the material blocking cover 16 is fixed at the bottom of the movable body 11, the material blocking cover 16 is connected with the fixed rod 17 below the outer side, the lower end of the fixed rod 17 is connected with the movable rod 18; the side wall of the screening disc 19 is provided with an opening, one end of the movable rod 18 is movably arranged in the opening on the screening disc 19, and the outer side of one end of the movable rod 18 is provided with two tabs, one of which is located on the inner side of the screening disc 19, and the other is located on the outer side of the screening disc 19, and the movable rod 18 is limited by the two tabs; the bottom of the screening disc 19 is symmetrically provided with a convex column on both sides, and the screening disc 19 is rotatably connected with the middle of the mounting rod 20 through the convex columns on both sides of the bottom, and the two ends of the mounting rod 20 are fixed on the mounting frame 4. A vibrator is arranged on one side of the screening disc 19, the screening disc 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 disc 19 is located above the conveying belt mechanism 3.

[0039] When the stripped stone and the crushed concrete fall into the screening disc 19, the vibrator on the screening disc 19 makes the screening disc 19 high-frequency shake, and the movable body 11 moving circumferentially and obliquely drives the material blocking cover 16 and the fixed rod 17 to move synchronously, the fixed rod 17 is movably connected with the screening disc 19 through the movable rod 18, so that when the movable rod 18 moves, the screening disc 19 swings up and down around the mounting rod 20, improving the screening effect of the crushed concrete and the stripped stone in the screening disc 19, and cooperating with the high-frequency vibration of the vibrator on the screening disc 19, so that the crushed concrete in the screening disc 19 gradually falls into the material stacking place 24 below through the screening holes of the screening disc 19, and the large pieces of concrete and stone on the screening disc 19 fall onto the conveying belt mechanism 3 feeding the crushing mechanism 2 below the left side for secondary crushing and stone stripping. The material stacking place 24 and the conveying belt mechanism 3 are independent mechanisms, and the material stacking place 24 is also provided with a conveying belt, and the conveying direction of the material stacking place 24 is opposite to the conveying direction of the conveying belt mechanism 3.

[0040] The working principle of the building waste recycling device for facilitating layered treatment is provided in the embodiment.

[0041] Before the building concrete solid waste is crushed, the operator first starts the vibrator and the electric push rod two 212 on the screening disc 19 in the crushing mechanism 2 on the right side, after the electric push rod two 212 is started, the plug body 213 is moved upward, so that the oil in the oil pressure cavity one 211 flows into the oil pressure cavity two 214 through the hose, the broken wall block 215 moves to the maximum position with the increase of the oil pressure cavity two 214, at this time the electric push rod two 212 continues to move upward, the pressure sensor on the plug body 213 detects that the pressure in the oil pressure cavity one 211 and the oil pressure cavity two 214 gradually increases, and when the pressure is adjusted to the corresponding crushing pressure of the concrete, the electric push rod two 212 is turned off.

[0042] Then the controller is opened to start the electric push rod 6, and according to the size of the building concrete solid waste to be crushed, the position of the feeding sleeve 7 in the installation box 5 is adjusted by the electric push rod 6, so that the gap between the inner wall below the feeding sleeve 7 and the broken wall block 215 outside the movable body 11 is appropriate, and then the controller is opened to start the motor 12, which drives the transmission rod 10 and the sliding rod 9 to rotate synchronously, and through the concave-convex matching of the sliding rod 9 and the connecting rod 8, the connecting rod 8 and the feeding sleeve 7 are driven to rotate synchronously, and then the building concrete waste is uniformly fed into the feeding hopper cover 71 through the external waste conveying mechanism.

[0043] When the building concrete solid waste enters the feeding sleeve 7, with the rotation of the feeding sleeve 7, the building concrete solid waste gradually enters between the feeding sleeve 7 and the movable body 11, and when the transmission rod 10 rotates to drive the top block 101 to rotate, the movable body 11 is contacted by the rotating top block 101, so that the movable body 11 moves circumferentially on the spherical structure above the transmission rod 10; At this time, the gap between the broken wall block 215 at the upper end of the inclined movable body 11 and the feeding sleeve 7 is reduced, and the building concrete solid waste is crushed.

[0044] When encountering building concrete solid waste with larger size and higher hardness, the pressure on the broken wall block 215 at the extruded stone will be greater than that when crushing the concrete waste, and the broken wall block 215 in the oil pressure cavity two 214 transmits the pressure to the oil pressure cavity one 211 through the oil, at this time the pressure sensor on the plug body 213 detects the change of the pressure value, and the controller adjusts the system to open the electric push rod two 212 to quickly adjust the position of the plug body 213 downward, so that the oil pressure cavity one 211 and the oil pressure cavity two 214 are quickly adjusted to the pressure value corresponding to the crushing of the concrete; During this process, when the plug body 213 moves downward, the broken wall block 215 at the extruded stone moves to the inside of the oil pressure cavity two 214, so that the space at this place becomes larger, and the larger stone falls down at this place, and falls together with the crushed concrete onto the screening disc 19, completing the stripping of the harder stone in the concrete.

[0045] When the stripped stone and the crushed concrete fall into the screening disc 19, the vibrator on the screening disc 19 makes the screening disc 19 high-frequency shake, and the movable body 11 drives the blocking cover 16 and the fixed rod 17 to move synchronously, the fixed rod 17 is movably connected with the screening disc 19 through the movable rod 18, so that when the movable rod 18 moves, the movable rod 18 drives the screening disc 19 to swing up and down around the mounting rod 20, and cooperates with the high-frequency vibration of the vibrator on the screening disc 19, so that the crushed concrete in the screening disc 19 gradually falls into the lower material stacking place 24 through the screen hole of the screening disc 19, and the concrete which is not fully crushed and the stripped stone on the screening disc 19 fall into the conveyor belt mechanism 3 from the discharge port on the left side of the screening disc 19, and are sent into the crushing mechanism 2 on the left side through the conveyor belt mechanism 3, and the crushing parameters of the crushing mechanism 2 on the left side are adjusted to complete the secondary crushing.

[0046] The above is a further detailed description of the present application in combination with specific preferred embodiments, and it cannot be considered that the specific embodiments of the present application are limited to this. For ordinary skilled persons in the technical field to which the present application belongs, a number of simple deductions or substitutions can be made without departing from the present application, and all of them should be considered as belonging to the scope of patent protection determined by the submitted claims.
