The left center of the collection bin 10 is fixedly connected with a discharge pipe 16, and a one-way valve 17 is installed in the discharge pipe 16, and the one-way valve 17 faces the left end. The left end outer wall of the discharge pipe 16 is provided with a thread, and the left end outer wall of the discharge pipe 16 is sleeved with the right end of the foam nozzle 18, and the left end of the discharge pipe 16 and the right end of the foam nozzle 18 are threadedly matched. Connection, the left side wall of the foam nozzle 18 is fixedly connected to the threaded tube 23, the right end of the discharge nozzle 19 is sleeved with the threaded tube 23, the right end of the discharge nozzle 19 is threadedly connected to the threaded tube 23, the discharge nozzle 19 is a tapered tube, and the inner diameter of the right end of the discharge nozzle 19 is larger than that of the left end. A handle 21 is fixedly connected between the top right end of the mounting frame 1 and the top of the flange 22, and the two ends of the handle 21 are respectively fixedly connected to the top of the flange 22 and the top right end of the mounting frame 1, and the handle 21 is L-shaped.
[0019] The bottom of the outer wall and the bottom of the collecting bin 10 are both fixedly connected with an air intake valve 13 , and the end of the air intake valve 13 is connected to a thread plug 25 .
[0020] A pressure gauge 20 is provided on the outer wall of the discharge pipe 16. The bottom of each leg 2 is threadedly connected to an adjusting bolt 27, which is inserted into the bottom of each leg 2. The solenoid valve 8 controls the action of the cylinder 6 and controls the reciprocating motion of the piston rod of the cylinder 6. An electromagnetic switch 26 is provided on the upper part of the cylinder 6, and the electromagnetic switch 26 controls the stroke of the piston rod of the cylinder 6.
[0021] The air inlet valve 13 is a one-way valve. After the foam spray head 18 is screwed off from the discharge pipe 16, the nut 24 is tightened with the threaded pipe 23, and the thread plug 25 is tightened with the air inlet valve 13, so that the grouting pump can be used like this.
[0022] The outer wall of the discharge pipe 16 is fixedly connected with a pressure gauge 20 , which can monitor the pressure in the discharge pipe 16 in real time.
[0023] Put the stirred mud into a container and insert a pipe into the mud, connect the other end of the pipe to the feed pipe 14 of the foam generator, connect the air pump to the cylinder 6 and the solenoid valve 8, and make sure that the battery 3 is charged and well connected. The user holds the mounting frame 1, the legs 2 or the handle 21 to stabilize the whole device, presses the switch 4, and starts the cylinder 6 and the solenoid valve 8;
[0024] When the piston rod of the cylinder 6 contracts to the right, the middle of the bladder 12 moves to the right, and negative pressure is formed in the bladder 12, so that the mud is sucked into the aggregate bin 10 through the feed pipe 14 (due to the existence of the one-way valve 15, the mud can only flow into the aggregate bin 10 in one direction), and at the same time, the external air enters the bladder 12 through the intake valve 13, so that the air and cement can be mixed. The intake valve 13 can only allow air to enter the inside of the bladder 12, and the air inside the bladder 12 cannot be discharged from the intake valve 13; the one-way valve 15 can only allow mud to enter the inside of the bladder 12. The solenoid valve 8, the battery 3 and the switch 4 are electrically connected, and the switch 4 controls the operation of the solenoid valve 8. The foam nozzle 18 is a foamer. The foam nozzle 18 is a prior art device.
[0025] This patent has two functions, the first is a device for foaming cement, and the second is a grouting pump.
[0026] When the piston rod of the cylinder 6 is pushed to the left, the middle of the bladder 12 moves to the left, and a positive pressure is formed in the bladder 12. Under the action of the pressure, the mud in the collection bin 10 is squeezed into the foam nozzle 18 through the discharge pipe 16 (the one-way valve 17 ensures the one-way outflow of the mud); the mud is mixed with air in the foam nozzle 18 to form foamed mud, and flows out through the discharge nozzle 19. The one-way valve 17 can only allow the mud to be discharged from the inside of the bladder 12, thus forming a foaming cement device. The air intake valve 13 will inhale a certain amount of air, so that the air can form foam with the cement slurry and pass through the foam nozzle 18 to effectively form foamed cement.
[0027] When the foam nozzle 18 is separated from the discharge pipe 16, the discharge pipe 16 is tightened with the nut 24, and the end of the inlet valve 13 is tightened with the plug 25, so that the cement slurry can enter from the feed pipe 14 and be discharged from the discharge pipe 16 through the operation of the cylinder 6, so that it can be used as a grouting pump. For larger gaps, a grouting pump can be used to fill them, and for smaller gaps, a device for forming foamed cement can be used to fill them.
[0028] When the two legs 2 are combined and brought close together, the user can work by hand. When the two legs 2 are separated and placed on the ground, the user can work on the ground. The length of the legs 2 can be adjusted by adjusting the length of the bolts 27 .
[0029] The present utility model only protects the mechanical part, and the related functions realized by the software control part are not within the protection scope of the present utility model.
