Description

Technical Field

[0001] This utility model relates to the field of delivery pumps, specifically a delivery pump with foreign object cutting effect. Background Technology

[0002] A transfer pump is a mechanical device used to transport liquids or slurries. It generates a pressure difference through a specific mechanism, transporting the liquid from a low-pressure area to a high-pressure area. Common transfer pumps include centrifugal pumps, plunger pumps, and screw pumps, each with a different working principle. For example, a centrifugal pump relies on a high-speed rotating impeller to generate centrifugal force, throwing the liquid out and gaining kinetic and pressure energy; a plunger pump changes the pump chamber volume through the reciprocating motion of the plunger, thereby achieving liquid suction and discharge. Current transfer pumps are not suitable for cutting foreign objects in the transported medium; therefore, a transfer pump with foreign object cutting capabilities is needed.

[0003] Existing transfer pumps are inconvenient to cut foreign objects in the transported medium during use. Larger foreign objects may block the pump inlet or internal channels, resulting in reduced flow or even complete interruption of transport, affecting production or project progress. They are also inconvenient to install pipelines quickly, affecting the efficiency of docking installation, and making it difficult to place the transfer pump stably. Therefore, there is an urgent need for a transfer pump with foreign object cutting effect. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a delivery pump with foreign object cutting effect, so as to solve the problems that existing delivery pumps are inconvenient to cut foreign objects in the conveying medium, inconvenient to quickly install pipelines, and inconvenient to stably place delivery pumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying pump with foreign object cutting effect, comprising a base, a conveying pump housing fixedly connected to the top of the base, a water outlet pipe fixedly connected to the top of the conveying pump housing, a sleeve fixedly connected to one side of the conveying pump housing, a first cutting blade installed on the inner wall of the sleeve, a drive motor fixedly connected to the top of the base, a rotating rod fixedly connected to the output shaft of the drive motor via a coupling, and a second cutting blade fixedly connected to the outer wall of the rotating rod.

[0006] A water inlet pipe is fixedly connected to one side of the sleeve. A limit rod is movably connected inside the water inlet pipe. A nut is installed on the outer wall of the limit rod. A connecting pipe is installed at one end of the water inlet pipe. An insert is fixedly connected to the outer wall of the connecting pipe.

[0007] The outer wall of the base is fixedly connected to a side plate, and the inside of the side plate is movably connected to a limit pin.

[0008] Preferably, the second cutting blade forms a rotating structure with the sleeve via a rotating rod, and the second cutting blade is arranged in a ring around the central axis of the rotating rod.

[0009] Preferably, the first cutting blades are arranged at equal intervals along the inner wall of the sleeve, and the first cutting blades and the second cutting blades are arranged parallel to each other.

[0010] Preferably, the limiting rod and the water inlet pipe form a rotating structure, and the limiting rod is T-shaped.

[0011] Preferably, the outer wall of the limiting rod is provided with threads, and the limiting rod is threadedly connected to the nut.

[0012] Preferably, the connecting pipe is engaged with the water inlet pipe, and the limiting rod is movably connected to the connecting pipe.

[0013] Preferably, the side plate has an open design, and the side plate and the limiting pin form a sliding structure.

With the cooperation of the first cutting blade and the second cutting blade, it can facilitate the cutting of foreign objects in the conveying medium and prevent foreign objects from clogging the conveying pump.

[0016] 2. This utility model, through the setting of an inlet pipe, a limiting rod, a nut, a connecting pipe, and a plug, allows the plug to be inserted into the inlet pipe by moving the connecting pipe. Pulling the limiting rod causes it to flip along the inlet pipe and lock into the groove at one end of the connecting pipe. Rotating the nut allows it to press against the connecting pipe, facilitating quick connection and installation of the inlet pipe and the connecting pipe, thus improving the efficiency of installation and use.

[0017] 3. This utility model, through the setting of a base, side plate and limiting nail, allows the base to be moved to the desired position, and the limiting nail to be moved and passed through the side plate, and the limiting nail to be hammered to insert into the soil, thereby improving the stability of the placement of the conveying pump.
