Therefore, when operating the reflux pump, the auxiliary device 4 can effectively protect the pump housing and the coupler 3, ensure the normal operation of the pump, and improve the stability and reliability of the equipment. The surface of the mounting cylinder 43 is fixedly connected with an L block 45 The screw 46 is threadedly connected to the short arm of the L block 45. The screw 46 moves with the help of the thread in the short arm of the L block 45. The L block 45 can prevent the screw 46 from losing contact with the mounting cylinder 43 and causing loss. An anti-skid pad 47 is glued to one end of the screw 46. The anti-skid pad 47 abuts against the inner wall of the circular groove 41. The anti-skid pad 47 is made of rubber, so that the anti-skid pad 47 abuts against the inner wall of the circular groove 41. The anti-skid pad 47 can increase the friction between the screw 46 and the circular groove 41, effectively preventing the screw 46 from sliding or moving during use, improving the fixing effect of the screw 46, and ensuring its stability. A sealing pad 44 is glued to the surface of the mounting cylinder 43, and the screw 46 passes through the sealing pad 44. The sealing pad 44 is made of rubber. The sealing pad 44 can seal the joint between the mounting cylinder 43 and the pump housing 1 to prevent dust from entering the drum 42 from the joint, thereby improving the transmission efficiency of the coupler 3.
[0032] Reference Figure 4 and Figure 5As shown, specifically, the docking device 5 includes a bottom plate 51, the bottom plate 51 is fixedly connected to the support leg 2, a slide groove 52 is provided on the surface of the bottom plate 51, and a placement frame 53 is slidably connected to the inner wall of the slide groove 52, and the coupler 3 is located in the placement frame 53. By setting the docking device 5, the coupler 3 can be quickly and conveniently docked and installed, avoiding the situation that the output end of the coupler 3 and the roller 42 have a high degree of fit and are difficult to dock, which can reduce the labor intensity of workers, improve work efficiency, and ensure the installation quality and accuracy of the coupler 3. The lower surface of the bottom plate 51 A pointed cone 55 is fixedly connected, and two spikes 56 are fixedly connected to the surface of the pointed cone 55.

[0033] Working principle: when the coupler 3 is needed to drive the pump, first insert the installation cylinder 43 into the surface of the pump housing, the roller 42 will move with the installation cylinder 43, and then push the installation cylinder 43, the installation cylinder 43 will drive the sealing gasket 44 to press against the surface of the pump housing 1, and then rotate the installation cylinder 43 to align the screw 46 with the circular groove 41, and as the screw 46 is rotated, the screw 46 moves with the help of the thread in the short arm of the L block 45, and at the same time, with the help of the thread movement of the inner wall of the circular groove 41, the movement of the screw 46 will drive the anti-skid pad 47 to move until the anti-skid pad 47 presses against the inner wall of the circular groove 41, and the installation of the roller 42 is completed at this time. The anti-skid pad 47 can increase the friction between the screw 46 and the circular groove 41, effectively preventing the screw 46 from sliding or moving during use, thereby improving the screw 46 The fixing effect ensures its stability. The sealing gasket 44 can seal the joint between the mounting cylinder 43 and the pump housing 1 to prevent dust from entering the roller 42 from the joint, thereby improving the transmission efficiency of the coupler 3. The L block 45 can prevent the screw 46 from being lost due to loss of contact with the mounting cylinder 43. By setting the auxiliary device 4, the opening and closing of the pump housing 1 caused by the reverse thrust can be effectively limited, thereby reducing the collision and friction between the pump housing 1 and the coupler 3, which can not only reduce the wear of parts, improve the reliability of the equipment, and extend the service life of the equipment, but also effectively reduce the failure rate of the reflux pump. Therefore, when operating the reflux pump, the auxiliary device 4 can effectively protect the pump housing and the coupler 3, ensure the normal operation of the pump, and improve the stability and reliability of the equipment.
[0034] When the coupler 3 is used to drive the pump to run, it is necessary to use the docking device 5 to dock it. First, the coupler 3 is placed in the placement frame 53.

After the placement is completed, the placement frame 53 is pushed, and the placement frame 53 slides along the inner wall of the slide groove 52 opened on the surface of the bottom plate 51, thereby driving the coupler 3 to move in the direction close to the pump housing 1 until the output end of the coupler 3 is inserted into the drum. 42, the surface of the bottom plate 51 is provided with a pointed cone 55 and a spur 56, and the pointed cone 55 and the spur 56 will be inserted into the ground. The pointed cone 55 and the spur 56 can improve the stability of the pump housing 1 and avoid shaking when installing the coupler 3. By setting the docking device 5, the coupler 3 can be quickly and conveniently docked and installed, avoiding the situation that the output end of the coupler 3 is difficult to dock with the roller 42 due to a high degree of fit, which can reduce the labor intensity of workers, improve work efficiency, and ensure the installation quality and accuracy of the coupler 3.
