In the above process, the slurry for grouting is stored in the grouting tank 1, and in the grouting process for a long time, the slurry needs to be detected many times to confirm that the cement content in the slurry is within the standard range, then the user can take out part of the slurry from the plurality of sampling pipes 33 through the sampler 35, and then detect the taken part of the slurry in the detection table 34 to judge whether the cement content in the slurry is within the standard range.
When the cement content of the slurry in the detection table 34 is low, the electric push rod 24 is started, the movable end of the electric push rod 24 drives the circular plate 8 to move downwards for a certain distance along the vertical direction, then the circular plate 8 drives the second circular ring block 13 and the first circular ring block 12 to synchronously move downwards for a certain distance, as shown in fig. 1 and 7, until the second cam 32 on the side wall of the second circular ring block 13 and the feeding block 3003 are positioned at the left side of the same horizontal plane, at the moment, the second magnetic spring 3004 in the original electrified state is powered off, then the second magnetic spring 3004 stretches for a certain distance after being powered off, and the second magnetic spring 3004 drives the feeding block 3003 to slide leftwards in a sealing way for a certain distance, so that the second cam 32 and the feeding block 3003 are convenient to contact against each other.
The motor 3 is started, the motor 3 is a forward and reverse rotation motor, firstly, the output end of the motor 3 rotates clockwise, then the output end of the motor 3 drives the main shaft 5 to rotate clockwise synchronously, a plurality of stirring blades 22 fixedly connected with the bottom of the main shaft 5 stir slurry, but the outer ring part of the one-way bearing 19 does not drive the reciprocating screw tube 21 to rotate through a plurality of matching rods 20, at the moment, the main shaft 5 drives the circular plate 8 to rotate synchronously through the spline 14 fixedly connected with the side wall of the main shaft 5, the circular plate 8 drives the second circular ring block 13 and the first circular ring block 12 to rotate synchronously through the first connecting rod 9, the swinging rod 10 and the second connecting rod 11, then the second cam 32 fixedly connected with the side wall of the second circular ring block 13 rotates synchronously, and meanwhile, the first cam 31 rotates synchronously, then the second cam 32 pushes the feeding block 3003 intermittently, so that the feeding block 3003 slides in a reciprocating sealing manner in the feeding box 3002, when the feeding block 3003 slides in a reciprocating sealing manner in the feeding box 3002 once, the blanking hole 3005 formed in the inner wall of the feeding block 3003 and the blanking hole 3006 are in the direction of the feeding box 3006, and the cement slurry is in the feeding hole 3006 and the feeding hole 3006 is in the feeding box 3006 and the feeding hole is in the feeding hole 3001, and the cement feeding hole is in the feeding hole 3001 and the cement feeding hole is in the feeding hole 3001.
When the content of the water body detected by the taken-out part of the slurry in the detecting table 34 is low, the first cam 31 on the side wall of the first ring block 12 can be located at the right side of the same horizontal plane of the water adding block 2303 by controlling the travelling distance of the movable end of the electric push rod 24, at this time, the output end of the motor 3 is still rotated clockwise, the output end of the motor 3 drives the spindle 5 to rotate clockwise, the spindle 5 still drives the second cam 32 and the first cam 31 to rotate through a plurality of connecting rods and other structures, and the first cam 31 pushes the water adding block 2303, so that the water adding block 2303 slides back and forth in the water adding box 2302 in a sealing way, and the water body in the water adding box 2301 is quantitatively added into the grouting tank 1 each time and mixed with the slurry, so that the content of the water body in the slurry is improved.
In the above process, the first magnetic spring 2304 and the second magnetic spring 3004 are both in the energized state when the power is not needed, and the principle of the magnetic spring can be briefly summarized as that one or more magnetic springs are mounted on a structural material through threads, and the magnetic springs interact with currents in an external magnetic field to generate tensile forces with different magnitudes so as to control the tensile deformation and the motion state of the springs, namely, the phenomenon that the magnetic springs shrink after being energized, and then the first magnetic spring 2304 drives the water adding block 2303 to hermetically slide leftwards for a certain distance after being energized, and the second magnetic spring 3004 drives the material adding block 3003 to hermetically slide rightwards for a certain distance after being energized, so that interference of downward movement of the first cam 31 and the second cam 32 by the water adding block 2303 and the material adding block 3003 is avoided.
When the slurry in the grouting tank 1 gradually reduces to be replenished, the electromagnet 28 is electrified, the polarities of the electrified electromagnet 28 and the magnetic limiting column 27 are the same and are magnetic repulsive force, and then the magnetic limiting column 27 slides a distance in a direction away from the electromagnet 28 under the action of the magnetic repulsive force, so that the magnetic limiting column 27 is inserted into the annular groove 29 to limit the circular plate 8. Then, when the output end of the motor 3 rotates anticlockwise, at this time, the spindle 5 still drives the first annular block 12 and the second annular block 13 to rotate anticlockwise through structures such as the circular plate 8, the plurality of connecting rods and the circular shaft 6, then the first cam 31 and the second cam 32 also synchronously rotate anticlockwise, but at this time, the spindle 5 drives the plurality of matching rods 20 and the reciprocating screw tube 21 through the one-way bearing 19, as the nut 18 is in threaded connection with the side wall of the reciprocating screw tube 21, and the inner side walls of the nut 18 and the first annular block 12 are embedded and slide, then the nut 18 drives the first annular block 12 to move downwards in the vertical direction, the first annular block 12 drives the swinging rod 10 to rotate by a certain angle through the second connecting rod 11, and the swinging rod 10 drives the first connecting rod 9 to move, so that the second annular block 13 and the circular plate 8 are mutually far away from each other, when the nut 18 moves downwards in the axial direction of the reciprocating screw tube 21 to the end of stroke, the motor 3 stops rotating reversely, and the side wall 31 of the first annular block 12 and the second cam 2303 are located at the left side wall of the second cam 30032 of the second annular block 3.
Then, the output end of the motor 3 rotates clockwise, the first cam 31 and the second cam 32 rotate synchronously, so that the first cam 31 extrudes and pushes the water adding block 2303, and the second cam 32 extrudes and pushes the water adding block 3003, so that water and water can be added into the grouting tank 1 to form slurry, and the volume ratio of cement and water can be controlled by setting the diameters of the blanking hole 3005, the charging pipe 3006 and the discharging hole 3007 and the diameters of the water falling hole 2305, the water adding pipe 2306 and the water discharging hole 2307.
