Description

oil rig

The present invention relates to an oil pumping device.

Generally speaking, to replace the fuel of a vehicle, etc., an oil pumping device with a suction function is often used to suck out the waste oil and then inject new oil. The oil pumping device can be roughly divided into handheld and Floor type. Usually, after the oil storage barrel of the oil pumping device is filled with oil, the overall weight will become heavier. If you want to move the oil pumping device, you need to lift the entire oil pumping device off the ground, making it impossible to carry the oil pumping device stably. The oil body is caused to shake in the oil storage barrel to make it easier to carry or dump.

Therefore, it is necessary to provide a novel and progressive oil pumping device to solve the above-mentioned problems.

The main purpose of the present invention is to provide an oil pumping device which is easy to move.

In order to achieve the above object, the present invention provides an oil pumping device, comprising: a barrel; a bottom, which is arranged on the barrel; liquid is sucked into the barrel; and at least one wheel, each of which is arranged on the bottom; wherein the pumping mechanism includes a pump, and an outer diameter of the pump is smaller than an outer diameter of the barrel; Wherein, the bottom is a base, the bottom includes a first base and a second base, the barrel is assembled on the first base, the pump is located outside the barrel and is assembled on the second base, each of the wheels The barrel body is arranged on the second base; wherein, the barrel body and the drawing mechanism are separately arranged at intervals.
