Figure 4 As shown, after completing a single material metering and conveying, the lifting drive assembly drives the pump cover assembly to rise and move away from the elastic hose 14, and the rotating drive assembly drives the rotating pipe pressing assembly to rotate back to the initial conveying position.
[0027] In this embodiment, by arranging the pump chamber, the rotating mechanism and the pump cover opening and closing mechanism on the mounting plate 2, a compact pipeline pump main structure is formed. Specifically, an elastic hose 14 is arranged inside the pump chamber, one end of the rotating tube pressing assembly is connected to the output end of the rotating drive assembly, and the other end is an inclined end and extends into the pump chamber to realize the extrusion of the elastic hose 14; one end of the pump cover assembly is hinged to the top of the pump chamber, and the other end is connected to the output end of the lifting drive assembly, so as to realize the flexible opening and closing of the pump cover assembly; when the pipeline pump is working, the lifting drive assembly drives the pump cover assembly to descend and cover the pump chamber and the top of the elastic hose 14, the rotating drive assembly drives the rotating tube pressing assembly to swing in a circle, and cooperates with the pump cover assembly to squeeze the elastic hose 14, that is, material conveying is realized; after completing the single material metering and conveying, the lifting drive assembly drives the pump cover assembly to rise and move away from the elastic hose 14, the elastic hose 14 is no longer subjected to the extrusion force, and the rotating drive assembly drives the rotating tube pressing assembly to rotate to the initial conveying position. The pipeline pump of this embodiment flips the pump cover assembly upward after each fluid filling, disengages the squeezing of the elastic hose 14, and at the same time, the rotating tube pressing assembly is reset to the initial position before filling through the rotating drive assembly. The initial position of the tube pressing assembly is the same during the next filling, that is, the rotating tube pressing assembly is reset to zero each time the filling is completed, which significantly improves the accuracy of repeated filling. At the same time, the elastic hose 14 can also periodically recover its elasticity, effectively extending the service life of the pump tube and reducing the operating cost of the pipeline pump.

The vertical end of the eccentric shaft 13 passes through the bearing seat 3 and is connected to the output shaft of the rotary motor 1. A bearing is provided between the eccentric shaft 13 and the bearing seat 3. The cone 10 is nested at the inclined end of the eccentric shaft 13 and is located below the elastic hose 14. Driven by the rotary motor 1, the eccentric shaft 13 drives the cone 10 to swing in a circular undulation and squeeze the bottom of the elastic hose 14. The pump cover assembly squeezes the elastic hose 14 to achieve material transportation.
[0031] In this embodiment, the bearing includes a tapered roller bearing 4 and a first deep groove ball bearing 5 which are arranged in sequence. A third hole elastic retaining ring 20 is provided at the connection between the bottom of the tapered roller bearing 4 and the eccentric shaft 13, and a first hole elastic retaining ring 6 is provided at the connection between the top of the first deep groove ball bearing 5 and the bearing seat 3.

Driven by the lifting motor 21, the guide assembly drives the pump cover 16 to flip and lift around the hinge assembly to open or close the top of the pump chamber, thereby achieving the pump cover 16 squeezing or releasing the elastic hose 14.
[0034] like Figure 3 As shown, in this embodiment, the hinge assembly includes: a lower support plate 8, an upper support plate 9 and a hinge 22. The lower support plate 8 and the upper support plate 9 are connected by the hinge 22, the lower support plate 8 is arranged on the side of the bushing 15, and the upper support plate 9 is arranged on the side of the pump cover 16.

One end of the guide column 18 is connected to the pump cover 16, and the other end of the guide column 18 is connected to the output end of the lifting motor 21. The guide sleeve 19 is arranged on the mounting plate 2 and nested in the outer periphery of the guide column 18.
[0036] Driven by the lifting motor 21, the pump cover 16 moves downward under the pulling force of the guide column 18, and re-compresses the elastic hose 14 with the cone 10 to perform the next filling action. While the elastic hose 14 recovers, the cone 10 rotates synchronously back to the initial position before the last filling, so that continuous filling can be achieved in the same phase.
[0037] like Figure 2 As shown, in this embodiment, a joint 17 is further provided on the pump chamber, and the joint 17 is connected to the elastic hose 14 to enable materials to enter and exit the pipeline pump.
[0038] In this embodiment, at the moment of each filling completion, the lifting motor 21 pushes the guide post 18 in the guide sleeve 19 upward, and the pump cover 16 is turned upward around the hinge 22 under the pushing action of the guide post 18 until it no longer squeezes the elastic hose 14 together with the cone 10. After the rotary motor 1 drives the eccentric shaft 13 and the cone 10 to rotate to the initial position before filling, the lifting motor 21 pulls the guide post 18 to move downward, and the guide post 18 pulls the pump cover 16 to rotate downward around the hinge 22, squeezing the elastic hose 14 together with the cone 10, and repeating a new filling operation. This reciprocating cycle realizes continuous filling in the same phase.
