The working principle of the invention is as follows:
When the PVC irrigation pipe is used, the cushion blocks 2 are firstly placed below the PVC irrigation pipe at equal intervals, the lower end surfaces of the cushion blocks 2 are contacted with the ground, and the lower rubber pads 202 in the circular arc grooves 201 of the cushion blocks 2 are contacted with the PVC irrigation pipe.
Then a plurality of fixing frames 1 pass through the PVC irrigation pipe and then are matched with the corresponding cushion blocks 2, so that the two vertical sections 102 of the fixing frames 1 are ensured to be downwards inserted into the two inserting grooves 203 of the cushion blocks 2 and downwards inserted into the ground until the upper rubber pads 103 on the arc sections 101 of the fixing frames 1 are tightly contacted with the PVC irrigation pipe. At this time, the bolts 204 are screwed down, so that the tips of the bolts 204 are tightly pressed on the vertical section 102 of the fixing frame 1, thereby realizing the fixed connection of the cushion block 2 and the fixing frame 1, and further realizing the integral fixed connection of the PVC irrigation pipe and the device.
Then, the glue pump 3 starts to work, glue enters the fixing frame 1 through the glue injection pipe 302 and the glue injection port 301, and the inside of the two vertical sections 102 of the fixing frame 1 is filled with glue. Glue enters the inside of the three air bags 410 through the three connecting holes 411, and as the glue is injected, the air bags 410 are continuously inflated, and a downward pressure is applied to the connecting ring 409, so that the connecting ring 409 slides downward inside the sliding groove 408. When the link 409 slides downward, the upper end of the link 412 descends simultaneously, and the lower end of the link 412 moves outward, so that the deployment arm 403 rotates outward from the inside of the storage groove 401 to expand gradually. Because the upper section 4031 of the deployment arm 403 is in a "plowshare" configuration, the drag between the deployment arm 403 and the soil is reduced, ensuring that the deployment arm 403 deploys smoothly.
When the connection ring 409 moves downward to the position where the locking post 504 corresponds to the locking groove 505, the locking post 504 is locked with the locking groove 505 under the action of the elastic force of the spring 502, the connection ring 409 cannot continue to move downward to reach the limit position, the deployment arm 403 deploys to the maximum angle to be limited, and the airbag 410 cannot continue to expand, as shown in fig. 16 and 17.
