Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, this utility model discloses a vertical anti-clogging mortar pump, including a motor 1 and a rotating shaft 2. The rotating shaft 2 is located at the center of the motor 1 and extends from one end of the motor 1. It also includes a linkage shaft 6 and an impeller 8. One end of the linkage shaft 6 is fixedly connected to the rotating shaft 2, and the other end of the linkage shaft 6 is fixedly connected to the impeller 8. A housing 3 is provided below the motor 1, and the housing 3 is fixedly connected to the outer shell of the motor 1. Four fixing blocks 31 are provided opposite to each other on the inner surface of the housing 3. The four fixing blocks 31 are respectively arranged at the upper and lower parts of the inner surface of the housing 3 along the axial direction of the linkage shaft 6. A through hole 76 is opened at the center of each fixing block 31 in the vertical direction. The retractable anti-clogging device 7 includes a connecting post 71 and a ring 73. The outer diameter of the connecting post 71 is smaller than the diameter of the through hole 76. The connecting post 71 passes through the through hole 76 and is fixedly connected to the ring 73. The inner wall of the through hole is smooth, and the connecting post can extend and retract within the through hole. The retractable anti-clogging device 7 also includes a spring 75 and at least four anti-clogging posts 74. In this embodiment, the number of anti-clogging posts 74 is eight. One end of the spring 75 is fixedly connected to the connecting post 71, and the other end is fixedly connected to the fixing block 31 located below. The anti-blocking posts 74 are evenly distributed on the lower surface of the ring 73. When the spring 75 is in the extended state, the elastic force of the spring 75 ensures that the ring 73 and the anti-blocking posts 74 connected to the telescopic rod 71 are freed from gravity and are in a relatively fixed position. The anti-blocking posts 74 are fixedly connected to the ring 73. The ring 73 has a ring hole 72 in the center. The diameter of the ring hole 72 is larger than the outer diameter of the linkage shaft 6. The linkage shaft extends downward through the ring hole to ensure that the 73 will not obstruct the linkage shaft 6 when it rotates.

[0021] As Figures 1-4 In the embodiment, one end of the linkage shaft 6 is fixedly connected with a rotating disc 5, the rotating disc 5 is arranged at one end close to the rotating shaft 2, two protrusions 51 are oppositely arranged at the edge of the lower surface of the rotating disc 5, the protrusions 51 are fixedly connected with the rotating disc 5, and the protrusions 51 are in the shape of wedges. The upper end of the connecting column 71 is matched with the wedge shape of the protrusions 51, so that the connecting column 71 can be closely matched with the protrusions 51. The lower end of the anti-blocking column 74 is in the shape of a taper. When the rotating disc 5 rotates with the linkage shaft 6, the protrusions 51 also rotate, and when the protrusions 51 are rotated to the position of the connecting column 71, the inclined surface of the wedge shape of the protrusions 51 is in contact with the inclined surface of the connecting column 71. When the rotating disc 5 continues to rotate, the protrusions 51 generate a vertical downward force on the connecting column 71, the connecting column 71 is pushed downward to tighten the spring 75, the ring 73 and the anti-blocking column 74 are pushed to move downward, and when the wedge shape of the protrusions 51 is out of contact with the connecting column 71, the connecting column 71 is no longer forced, so that the spring 75 rebounds, the connecting column 71 and the anti-blocking column 74 of the ring are moved upward, and the cycle is repeated.

[0022] As Figures 1-4 In the embodiment, the outer periphery of the impeller 8 is provided with the mixing device 4, the lower end of the shell 3 is designed as a hollow lattice 32, and the mixing device 4 is fixedly connected with the hollow lattice 32. The hollow lattice can prevent large slag blocks from entering the pump and causing large blockage. The side surface of the mixing device 4 is provided with a discharge port 42, the upper surface of the mixing device 4 is provided with a feeding hole 41, the diameter of the feeding hole 41 is much larger than the outer diameter of the anti-blocking column 74, and the feeding hole 41 corresponds to the position of the anti-blocking column 74, so that the anti-blocking column 74 can extend into the mixing device 4. When the mortar slag is blocked between the feeding hole 41 and the anti-blocking column 74, the anti-blocking device 7 moves, and then drives the anti-blocking column 74 to perform the up-down reciprocating ramming action. When the anti-blocking column 74 is lifted, the position of the blocked mortar slag can be changed. When the anti-blocking column 74 falls downward, the mortar slag is pushed to fall into the feeding hole 41, so as to prevent the mortar slag from blocking the feeding hole 41. The upper surface of the mixing device 4 is further provided with a movable hole 43, the diameter of the movable hole 43 is larger than the outer diameter of the linkage shaft 6, so that the movable hole 43 does not hinder the linkage shaft 6 when the linkage shaft 6 rotates.

[0023] The rotating disc rotates with the connecting shaft, drives the anti-blocking device to perform the up-down reciprocating movement, drives the anti-blocking column to perform the ramming action in the feeding hole, prevents the mortar slag from blocking the feeding hole, causes long-time shutdown for maintenance, and improves the operation efficiency of the vertical mortar pump.

[0024] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
