[0025] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the extrusion assembly includes a mounting seat 20 installed at one end of the top of the bent pipe 2, one side of the mounting seat 20 is overlapped with a lap seat 21, one side of the lap seat 21 is fixedly connected to the outer wall of the discharge pipe 1, and an inner end of the lap seat 21 is slidably connected to a movable rod 22, and a torsion ring 23 is installed at one end of the movable rod 22. A reset groove is opened inside the lap seat 21 on the outer side of the movable rod 22, and a reset plate 24 is slidably connected to the inner side of the reset groove. The reset plate 24 is rotatably connected to the movable rod 22, and a first spring 25 is installed between the two ends of one side of the reset plate 24 and the inner wall of the reset groove. Further, when assembling the bent pipe 2 and the discharge pipe 1, it can be placed on the top of the bent pipe 2 first, so that the lap seat 21 is overlapped on the top surface of the mounting seat 20, and then the torsion ring 23 is buckled and pressed to drive the movable rod 22 to move downward, and the reset plate 24 simultaneously moves and stretches the two sets of first springs 25, and the positioning block 26 enters the inner side of the mounting groove and engages with the positioning groove on the movable disk 32 to complete the preliminary docking combination.

[0026] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, a positioning block 26 is installed at the other end of the reset plate 24, and a clamping block 27 is installed on the outer wall of the movable rod 22 between the reset plate 24 and the positioning block 26. A recovery groove is opened at one end of the movable rod 22 inside the lap seat 21, and the end of the recovery groove is fitted to the outer wall of the mounting seat 20. Further, the movable rod 22 is continued to be pressed down, so that the positioning block 26 cooperates with the positioning groove to press the movable disk 32 and the extrusion plate 31, so that the clamping block 27 is completely moved from the inside of the docking groove to the inside of the rotating groove 28, and then the torsion ring 23 is twisted to drive the movable rod 22 to rotate, and the clamping block 27 rotates to the horizontal direction in the rotating groove 28.

[0027] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the locking assembly includes a docking groove opened at the top of the mounting seat 20, the docking groove and the block 27 are slidably connected, the block 27 and the docking groove are slidably connected, a rotating groove 28 is opened inside the mounting seat 20 on one side of the docking groove, an extension groove 29 is opened inside the mounting seat 20 on the other side of the rotating groove 28, and a spring-pressing groove is opened inside the mounting seat 20 on the other side of the extension groove 29, and second springs 30 are installed on both sides of the inner wall of the spring-pressing groove. Further, until the block 27 is aligned with the horizontal slot 33, the torsion ring 23 is loosened back, and the two groups of first springs 25 drive the reset plate 24 to retract, and the two groups of second springs 30 drive the extrusion plate 31 and the movable disk 32 to rebound, driving the block 27 to move accordingly, so that the block 27 is pressed against the inner side of the slot 33, thereby completing the locking of the elbow 2 and the discharge pipe 1.

[0028] In this embodiment, if Figure 6 , Figure 7 and Figure 8As shown, an extrusion plate 31 is installed at the other end of the second spring 30, and a movable disk 32 is rotatably connected inside the extrusion plate 31. A positioning groove that is engaged with the positioning block 26 is opened on one side of the movable disk 32. A clamping groove 33 is opened at both ends of the top of the inner wall of the rotating groove 28 inside the mounting seat 20, and the clamping groove 33 is engaged with the clamping block 27. Furthermore, when the valve seat 4 and the ball valve 5 are inspected and repaired by separating the elbow 2 and the discharge pipe 1, it is only necessary to buckle the torsion ring 23 and drive the movable rod 22 downward again. When the clamping block 27 is separated from the inner side of the clamping groove 33, the torsion ring 23 is twisted to drive the clamping block 27 to rotate to the longitudinal direction again. After aligning with the port of the docking groove, the torsion ring 23 is sent upward to allow the clamping block 27 and the positioning block 26 to retract to the inside of the recovery groove. At this time, the two sides of the discharge pipe 1 can be held to separate it from the lap seat 21 and the top of the elbow 2 to complete the separation operation.

[0029] The implementation principle of a mortar pump valve clearing device according to the embodiment of the present application is as follows: hold the rotating wheel 11 and press downward to cooperate with the linkage plate 9 and the sliding rod to drive the push rod 6 to retract a certain distance, and at the same time drive the pressure block 16 and the mounting plate 14 to move downward, so that the pressure block 16 is separated from the pressure groove, and the rotating wheel 11 is rotated to cooperate with the two sets of sprocket wheels 10 and the chain, so that the rotating plate 15 drives the pressure block 16 to rotate to a position horizontally located between the two sets of fixed plates 19, and then release the rotating wheel 11. At this time, the connecting spring 17 loses its restriction and immediately drives the pressure block 16 to rebound, forcing the push rod 6 to push upward along the through hole 13, lifting the ball valve 5 to ensure the circulation effect, and the rotating wheel can be held again when not in use. 11 is pushed downward to allow the linkage plate 9 to move along the track of the slide bar to prevent the installation cover 8 from deflecting when pressed down, and the pressing block 16 on the push rod 6 and the installation plate 14 are pulled downward again, so that the pressing block 16 slides downward between the two sets of fixed plates 19, and the rotating wheel 11 is twisted again to use the two sets of sprockets 10 and chains to make the pressing block 16 rotate to the longitudinal direction again and snap into the inner side of the pressing groove again, so as to achieve the effect of retracting the push rod 6 to the inner side of the protective cover 12. When assembling the elbow 2 and the discharge pipe 1, it can be placed on the top of the elbow 2 first, so that the lap seat 21 overlaps the top surface of the installation seat 20, and then the torsion ring 23 is buckled to press and drive the movable rod 22 The movable rod 22 moves downward, and the reset plate 24 moves and stretches the two sets of first springs 25 at the same time. The positioning block 26 enters the inner side of the installation groove and engages with the positioning groove on the movable disk 32 to complete the preliminary docking combination. The movable rod 22 is continued to be pressed down, and the positioning block 26 cooperates with the positioning groove to press the movable disk 32 and the extrusion plate 31, so that the clamping block 27 moves completely from the inner side of the docking groove to the inner side of the rotating groove 28. Then, the torsion ring 23 is twisted to drive the movable rod 22 to rotate. The clamping block 27 rotates to the horizontal direction in the rotating groove 28 until the clamping block 27 is aligned with the horizontal clamping groove 33. Then, the torsion ring 23 is loosened back, and the two sets of first springs 25 drive the reset plate 24 to retract. The two sets of second springs 30 drive the extrusion plate 31 to move the movable rod 22 to the inner side of the rotating groove 28. The plate 31 and the movable disk 32 rebound, driving the block 27 to move accordingly, so that the block 27 is pressed against the inner side of the groove 33, completing the locking connection between the elbow 2 and the discharge pipe 1. When the elbow 2 and the discharge pipe 1 are separated for inspection of the valve seat 4 and the ball valve 5, it is only necessary to buckle the torsion ring 23 and drive the movable rod 22 downward again. When the block 27 is separated from the inner side of the groove 33, the torsion ring 23 is twisted to drive the block 27 to rotate longitudinally again. After aligning with the port of the docking groove, the torsion ring 23 is sent upward to allow the block 27 and the positioning block 26 to retract to the inner side of the recovery groove. At this time, the two sides of the discharge pipe 1 can be held to separate it from the lap seat 21 and the top of the elbow 2 to complete the separation operation.
