Technical Field
[0001] This utility model relates to the field of industrial technology, specifically to a multi-axis, multi-functional rotary piston pump. Background Technology
[0002] Piston pumps, also known as electric reciprocating pumps, are structurally divided into single-cylinder and multi-cylinder types, characterized by their high head. They are suitable for conveying oil emulsions and other liquids without solid particles at room temperature. Applications include water injection, oil injection, and oil extraction in oil fields and coal seams; power pumps for hydraulic presses; hydraulic sand removal; and conveying ammonia in fertilizer plants. Therefore, this project proposes a multi-shaft, multi-functional rotary piston pump.
[0003] Existing piston pumps have complex and time-consuming operation processes, which affect the efficiency of continuous operation and have poor flexibility. Therefore, this project proposes a multi-axis, multi-functional rotary piston pump. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-axis, multi-functional rotary piston pump, which solves the problems of the complex and time-consuming working process of existing piston pumps, which affects the efficiency of continuous operation and has poor flexibility. Therefore, this invention provides a multi-axis, multi-functional rotary piston pump.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-axis, multi-functional rotary piston pump, including a mounting frame, a piston pump body mounted on the top of the mounting frame, a motor mounted on the rear side of the top of the mounting frame, a rotating shaft provided at the output end of the motor, a rotating shaft installed inside the piston pump body, and the rotating shaft and a rotating disk forming a fixed structure.
[0006] Preferably, an inlet and an outlet are respectively provided on the left and right sides of the outer side of the piston pump body, an installation ring is fixedly connected inside the piston pump body, an installation ring is fitted to the outer side of the transmission shaft, and the rotating disk and the transmission shaft constitute a transmission structure.
[0007] Preferably, a fixed rod is connected through the inside of the drive shaft, and a telescopic rod is slidably connected to the outside of the fixed rod. The movable disc and the telescopic rod form a fixed structure, and the movable disc and the fixed rod form a movable structure through the telescopic rod.
[0008] Preferably, a fixing ring is installed inside the piston pump body, and several material storage slots are opened inside the fixing ring. The movable disc forms a sliding structure with the material storage slots through a telescopic rod.
[0009] Preferably, the fixed ring forms a transmission structure with the piston pump body through the movable disc, and the movable disc is arranged in several groups around the fixed ring.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model is equipped with a rotating shaft. When the motor is started, the rotating shaft drives the rotating disk to rotate, which in turn pushes the transmission shaft to slide within the inner diameter of the mounting ring. This causes the movable disk to rotate as well. When the worker pours the material into each storage tank through the inlet, the corresponding movable disks fix the material under the action of rotation. Then, as the movable disk drives the fixing ring to rotate, when it rotates to the corresponding position of the outlet, the material is poured out from the storage tank, thus fulfilling the purpose of material transportation. The working process is simple and clear, and it is easy for the worker to observe.
[0012] 2. This utility model features a telescopic rod. When workers pour materials into the storage tank through the inlet, the telescopic rod retracts due to gravity, causing the movable disc to slide and retract inside the storage tank, thus storing the materials. When the rod rotates to the outlet position, the materials flow out due to inertia, and the telescopic rod extends the movable disc, pushing the materials inside the storage tank, facilitating unloading and improving work efficiency.

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.
[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0019] Example 1
[0020] Please see Figure 1-3 This utility model provides a technical solution: a multi-axis multi-functional rotary piston pump, including a mounting frame 1, characterized in that: a piston pump body 2 is mounted on the top of the mounting frame 1, a motor 3 is mounted on the rear side of the top of the mounting frame 1, a rotating shaft 6 is provided at the output end of the motor 3, the rotating shaft 6 is installed inside the piston pump body 2, the rotating shaft 6 and the rotating disk 7 form a fixed structure, and the rotating shaft 6 drives the rotating disk 7 to rotate under the action of the motor 3.
[0021] Example 2
[0022] Similar to Embodiment 1, except that the piston pump body 2 has an inlet 4 and an outlet 5 on its outer left and right sides respectively, and an installation ring 14 is fixedly connected inside the piston pump body 2. The drive shaft 8 is fitted with the installation ring 14 on its outer side. The rotating disk 7 and the drive shaft 8 form a transmission structure, which pushes the drive shaft 8 to slide within the inner diameter of the installation ring 14.
[0023] Example 3
[0024] Similar to Embodiment 2, except that a fixed rod 9 is connected through the inside of the drive shaft 8, and a telescopic rod 10 is slidably connected to the outside of the fixed rod 9. The movable disc 11 and the telescopic rod 10 form a fixed structure, and the movable disc 11 and the fixed rod 9 form a movable structure through the telescopic rod 10. When the worker pours the material into each storage tank 13 through the feed port 4, the telescopic rod 10 is contracted by gravity, and the movable disc 11 slides and contracts inside the storage tank 13.
[0025] Example 4
[0026] Similar to Embodiment 1, except that a fixed ring 12 is installed inside the piston pump body 2, and several storage tanks 13 are opened inside the fixed ring 12. The movable disc 11 forms a sliding structure with the storage tanks 13 through the telescopic rod 10. Thus, the telescopic rod 10 drives the movable disc 11 to extend, which pushes the material inside the storage tanks 13, and at the same time, it also stores the material.
[0027] Example 5
[0028] Similar to Embodiment 4, except that the fixed ring 12 forms a transmission structure with the piston pump body 2 through the movable disc 11. The movable disc 11 is provided with several sets of fixed rings 12, so that the fixed ring 12 rotates with the movable disc 11 through the storage tank 13.
[0029] Working Principle: For this type of multi-shaft, multi-functional rotary piston pump, when the operator needs to transport materials, the motor 3 is started first. The rotating shaft 6, driven by the motor 3, rotates the rotating disc 7, pushing the transmission shaft 8 to slide within the mounting ring 14. This causes the movable disc 11 to rotate. When the operator pours materials into the storage tanks 13 through the inlet 4, the telescopic rod 10 retracts due to gravity, and the movable disc 11 slides and retracts inside the storage tank 13, thus storing the materials. During rotation, the corresponding movable discs 11 store the materials. When the pump rotates to the corresponding position at the outlet 5, the materials flow out from the outlet 5 due to inertia. The telescopic rod 10 then extends the movable disc 11, pushing the materials inside the storage tank 13, facilitating unloading and improving work efficiency. This fulfills the purpose of material transport, and the working process is simple and easy for operators to understand.
