[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0015] As Figure 1 and Figure 2 shown, a barrel-type lubricating pump includes an electric lubricating pump and a protective barrel 10; the electric lubricating pump includes a motor 1, an oil storage cavity 2 and an oil suction pump assembly; a drain port 8 and an oil cavity installation port 9 are provided at the bottom of the motor 1; the oil storage cavity 2 is connected to the motor 1 through the external thread of the oil cavity installation port 9; the protective barrel 10 is provided with an upper cover 3 at the top; the oil storage cavity 2 is located at the center position of the top of the upper cover 3, and the oil storage cavity 2 is connected to the upper cover 3 through a thread; a grease barrel 7 is provided inside the protective barrel 10; the oil suction pump assembly includes a vertical oil delivery pipe 5; the top of the oil delivery pipe 5 is connected to the oil storage cavity 2 through a thread, and the bottom of the oil delivery pipe 5 extends downward through the upper cover 3 at the top of the protective barrel 10 and into the bottom of the grease barrel 7; the grease barrel 7 is located inside the protective barrel 10 and is provided with an upper cover 3 at the top, which can protect the grease barrel from being knocked and the grease in the barrel from being polluted; among them, the grease barrel 7 is a finished product barreled lubricating grease sold in the market, including but not limited to barreled lubricating greases of specifications such as 15 kg and 18 kg.
[0016] A coupling 11 is provided at the top of the oil delivery pipe 5, and the coupling 11 is connected to the rotating shaft of the motor 1; the bottom of the oil suction pump assembly is a plunger pump body, a spatial cam is provided at the rear side of the pump body, the surface of the spatial cam is a wheel rotation groove, and a bolt is provided in the groove; the bolt is connected to the plunger in the pump body. When the coupling controls the spatial cam to rotate, the bolt moves in the groove to control the reciprocating movement of the plunger, so that the grease in the grease bucket is sucked into the pump body.
[0017] A compression spring 4 is provided outside the oil delivery pipe 5; a pressure oil disc 6 is installed at the bottom of the compression spring 4, and a silica gel scraping ring is provided on the outer ring of the pressure oil disc 6; the silica gel scraping ring can prevent grease from sticking to the inner wall of the oil bucket during consumption, and at the same time prevent cavitation caused by poor grease flow, resulting in excessive residual grease.
