[0019] See also Figure 1-4 The utility model provides a barrel pump liquid supply device, comprising:

[0020] It includes a plate seat 5, and a motor 1 and a liquid pumping component 2 are respectively installed on the top and bottom of the plate seat 5, the output end of the motor 1 passes through the plate seat 5 and is connected with the liquid pumping component 2, and the motor 1 is used to provide liquid pumping power to the liquid pumping component 2; the liquid pumping component 2 is connected to a liquid outlet pipe 3 on one side close to the output end of the motor 1, and the liquid pumping component 2 includes a fixed cylinder 21 and a sliding cylinder 22, the fixed cylinder 21 is fixedly arranged at the bottom of the plate seat 5 and coaxially arranged on the outside of the output shaft of the motor 1, the sliding cylinder 22 is inserted on the lower inner side of the fixed cylinder 21, and the insertion length of the sliding cylinder 22 is adjustable, and the liquid pumping component 2 can be applied to oil drums of different depth specifications by adjusting the insertion length of the sliding cylinder 22, and a limiting component 4 is arranged at the bottom of the liquid pumping component 2 for limiting the position after the liquid pumping component 2 touches the bottom.

[0021] It needs to be explained that when in use, the liquid pumping component 2 is inserted into the liquid supply barrel, and the slide tube 22 of the liquid pumping component 2 is controlled to extend. When the limit component 4 touches the bottom, the length adjustment of the liquid pumping component 2 is stopped, so as to avoid the problem that the liquid pumping depth of the liquid pumping tube of the barrel pump in the barrel pump liquid supply device is fixed, and liquid supply barrels of different specifications cannot be pumped, resulting in poor versatility.

[0022] In this embodiment, the pumping assembly 2 also includes an electric telescopic rod 23 installed in the fixed cylinder 21, the sleeve end of the electric telescopic rod 23 is coaxially fixed to the lower end of the output shaft of the motor 1, and the sliding rod end of the electric telescopic rod 23 is fixed with a rotating shaft 24 through a coupling, and a spiral blade 25 is provided on the outer side of the lower part of the rotating shaft 24, and the outer diameter of the spiral blade 25 is adapted to the inner diameter of the sliding cylinder 22, and a stabilizing cylinder 26 is fixed in the fixed cylinder 21 and the sliding cylinder 22 respectively, and the rotating shaft 24 passes through the stabilizing cylinder 26, and the rotating shaft 24 and the stabilizing cylinder 26 are rotatably and slidably matched, and the stabilizing cylinder 26 is located above the spiral blade 25, and a limit stop ring is also provided on the shaft body of the rotating shaft 24, and the limit stop ring is located at the upper and lower end surfaces of the stabilizing cylinder 26 in the sliding cylinder 22, and an installation cavity 241 is opened at the lower end of the rotating shaft 24.

[0023] When this embodiment is implemented, the slide 22 is driven to rise and fall by the electric telescopic rod 23, and the pumping depth of the pumping assembly 2 is quickly changed to pump liquid from liquid supply barrels of different specifications. When pumping liquid, the motor 1 is started to drive the rotating shaft 24 and the spiral blade 25 to rotate quickly to extract the liquid in the liquid supply barrel. The rotating shaft 24 is limited by the stabilizing cylinder 26 to increase the stability of the rotating shaft 24 during rotation, reduce the swing of the rotating shaft 24, and reduce noise.

[0024] In this embodiment, a filter cover 27 is provided at the lower end of the slide cylinder 22 for filtering the extracted liquid to avoid clogging of the device.

[0025] In this embodiment, a reduced diameter section is provided on the outer side of the upper end of the slide 22, and an expanded diameter section is provided on the inner side of the lower end of the fixed cylinder 21. The expanded diameter section and the reduced diameter section are slidably inserted and matched, and the reduced diameter section and the expanded diameter section have the same length. A plurality of convex strips 221 are provided on the outer peripheral side of the reduced diameter section along the axial direction, and a plurality of slide grooves 211 are provided on the inner peripheral side of the expanded diameter section corresponding to the convex strips 221. When the reduced diameter section and the expanded diameter section are fully inserted, the inner diameters of the fixed cylinder 21 and the slide 22 are completely consistent. The slide 22 is rotationally limited by the provision of the convex strips 221 and the slide grooves 211 to prevent the slide 22 from rotating synchronously with the rotating shaft 24 and reduce the pumping efficiency.

[0026] In this embodiment, the stabilizing cylinder 26 includes: an outer cylinder 261 and an inner cylinder 262, the outer cylinder 261 is fixedly mounted on the inner wall of the fixed cylinder 21 or the sliding cylinder 22, the inner cylinder 262 is rotatably connected to the rotating shaft 24, a plurality of spiral connecting plates 263 are evenly distributed on the outer peripheral side of the inner cylinder 262, the spiral connecting plates 263 have the same spiral angle as that of the spiral blades 25, and a buffer sleeve 264 is glued to the inner side of the inner cylinder 262.

[0027] It needs to be explained that when the liquid is transported by the spiral blades 25, the liquid moves upward in a spiral shape. Through the setting of the spiral connecting plate 263, on the one hand, it participates in the construction of the stabilizing cylinder 26 to support the rotating shaft 24 for stabilization and noise reduction. On the other hand, it can reduce the kinetic energy loss during liquid transmission and improve the suction efficiency. Among them, the buffer sleeve 264 is made of corrosion-resistant and wear-resistant material.

[0028] In this embodiment, the limiting assembly 4 includes: a touch rod 41, a slider 42 is arranged at the upper end of the touch rod 41, the lower end of the touch rod 41 passes through the filter cover 27, the slider 42 is slidably arranged in the installation cavity 241, and a buffer spring 43 is arranged between the slider 42 and the bottom of the installation cavity 241.

[0029] In this embodiment, a pressure sensing unit is disposed on a side of the slider 42 close to the buffer spring 43 .

[0030] That is to say, when the touch rod 41 contacts the bottom of the liquid supply barrel, the buffer spring 43 is compressed. When the pressure sensing unit reaches the preset monitoring pressure threshold, a signal is sent to the control unit of the electric telescopic rod 23, so that the electric telescopic rod 23 stops extending, thereby avoiding the excessive length of the liquid pumping component 2 affecting its use.

[0031] During specific implementation, the pumping assembly is inserted into the liquid supply barrel, and the slide tube of the pumping assembly is controlled to extend. When the limit assembly touches the bottom, the length adjustment of the pumping assembly is stopped to avoid the problem that the pumping depth of the pumping tube of the barrel pump in the barrel pump liquid supply device is fixed, and liquid supply barrels of different specifications cannot be pumped, resulting in poor versatility.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
