Description

Technical Field

[0001] This application relates to the field of lubrication pumps, and more particularly to an electric lubrication pump. Background Technology

[0002] As a lubrication device, the lubrication pump is mainly used to lubricate mechanical equipment periodically in order to reduce frictional resistance between mechanical equipment and slow down wear.

[0003] Chinese Patent CN209705685U discloses a lubrication pump, including an oil tank mechanism and an oil tank seat for mounting the oil tank mechanism. The oil tank seat is provided with an oil inlet and an oil outlet. The oil tank mechanism includes an encapsulation wall and a cavity defined by the encapsulation wall. One end of the encapsulation wall is connected to the oil tank seat. The encapsulation wall is provided with an outwardly extending exhaust pipe. An exhaust valve assembly is connected to the upper end of the exhaust pipe. The exhaust valve assembly includes an inner cavity and an exhaust port. A float ball is fitted with the inner cavity with clearance. A piston mechanism is provided in the cavity. The piston mechanism divides the cavity into an oil storage chamber and an air chamber. Both the oil inlet and the oil outlet are connected to the oil storage chamber.

[0004] Regarding the aforementioned technologies, when electric lubrication pumps process dry lubricating oil, the oil's viscous consistency and slow flow rate result in a small oil discharge volume, which affects the lubrication effect. Utility Model Content

[0005] In order to increase the oil discharge and improve the lubrication effect, this application provides an electric lubrication pump.

[0006] The electric lubrication pump provided in this application adopts the following technical solution:

[0007] An electric lubrication pump includes a base and an oil storage tank. The oil storage tank is connected to the base and is connected to a grease return pipe and a grease outlet pipe. A scraper is rotatably connected inside the oil storage tank, and a rotating component is connected to the scraper. The rotating component is used to drive the scraper to rotate and agitate the lubricating oil.

[0008] By adopting the above technical solution, when in use, the lubricating oil in the oil storage tank is discharged from the oil storage tank through the grease outlet pipe. The rotating part drives the scraper to rotate, which makes the scraper stir the lubricating oil, accelerates the rate at which the lubricating oil is discharged from the oil storage tank, increases the oil discharge volume of the oil storage tank, and improves the lubrication effect.

[0009] Optionally, the scraper rotates in the same direction as the oil storage tank radially. The rotating component is a first motor. The output shaft of the first motor is connected to one end of the scraper. An auxiliary plate is connected to one side of the scraper along its width direction. One end of the auxiliary plate is connected to the scraper, and the other end of the auxiliary plate is inclined away from the bottom of the oil storage tank.

[0010] By adopting the above technical solution, during use, the rotating component drives the scraper to rotate. When the scraper agitates the lubricating oil, the auxiliary plate comes into contact with the lubricating oil. Under the guidance of the auxiliary plate, the auxiliary plate pushes the lubricating oil closer to the bottom of the oil storage tank, thereby further accelerating the discharge of lubricating oil from the oil storage tank, increasing the oil discharge volume of the oil storage tank, and improving the lubrication effect.

[0011] Optionally, a liquid level detector is connected inside the oil storage tank. The liquid level detector is located near the bottom of the oil storage tank. The liquid level detector is electrically connected to a controller. The controller is electrically connected to an indicator light. The indicator light is connected to the base. The liquid level detector is used to detect the distance between the lubricating oil level in the oil storage tank and the liquid level detector and outputs the distance value. The controller is used to receive the distance value and calculate the liquid level value based on the distance value. When the controller receives the distance value, the controller controls the indicator light to light up.

[0012] By adopting the above technical solution, when the lubricating oil level in the oil storage tank drops below the level detector, the level detector detects the distance between the liquid surface and the level detector and outputs the distance value. The controller receives the distance value and obtains the liquid level value based on the distance value. When the controller receives the distance value, the controller controls the indicator light to light up, thereby prompting the operator to add lubricating oil in time.

[0013] Optionally, the oil storage tank has an opening at one end away from the base, and a mounting cover is connected to the top of the oil storage tank. The mounting cover is used to seal the top opening of the oil storage tank and is detachably connected to the oil storage tank.

[0014] By adopting the above technical solution, when cleaning the oil storage tank, the mounting cover is unlocked from the top of the oil storage tank by the locking device. After the mounting cover is unlocked, it is moved away from the top of the oil storage tank, thereby opening the top opening of the oil storage tank, which makes it easier for operators to clean the oil storage tank.

[0015] Optionally, a handle is attached to the top of the mounting cover.

[0016] By adopting the above technical solution, a handle is added to facilitate the operator in removing and taking the installation cover.

[0017] Optionally, the output shaft of the first motor is connected to a connecting rod, and one end of the scraper along its length is detachably connected to the top of the connecting rod by bolts.

[0018] By adopting the above technical solution, lubricating oil is easily stuck to the surface of the scraper after long-term use. When the oil storage tank stores different types of oil, the surface of the scraper needs to be cleaned. The scraper is detachably connected to the connecting rod by bolts, which facilitates cleaning or replacement of the scraper.

[0019] Optionally, a movable rod is connected to one end of the scraper near the opening of the oil storage tank. The length direction of the movable rod is consistent with the length direction of the oil storage tank. A connecting groove is provided at one end of the movable rod near the scraper. The length direction of the connecting groove is consistent with the length direction of the movable rod. The mounting cover is slidably connected to the oil storage tank along its length direction. An mounting rod is connected to the output shaft of the first motor. The length direction of the mounting rod is consistent with the length direction of the oil storage tank. The mounting rod passes through and is slidably connected to the scraper along its length direction. The mounting rod is also slidably connected to the connecting groove along its length direction. In use, the top of the movable rod contacts the inner wall of the mounting cover.

[0020] By adopting the above technical solution, when disassembling the scraper, the mounting cover is removed from one end of the oil storage tank, and the moving rod is moved along the length of the moving rod, so that the mounting rod is connected to the connecting groove and the scraper along its length, and the mounting rod is moved away from the scraper and the moving rod. The moving rod moves along its length, so that the scraper moves with the scraper, and the scraper and the moving rod are moved away from the oil storage tank, thereby facilitating the cleaning and replacement of the scraper.

[0021] Optionally, the scraper has a connection port that communicates with a connection groove. The mounting rod passes through and slides within the connection port along its length. A first limiting groove is formed on the inner wall of the connection port, with the length direction of the first limiting groove aligned with the length direction of the mounting rod. A second limiting groove is formed on the inner wall of the connection groove, with the length direction of the second limiting groove aligned with the length direction of the mounting rod. The first limiting groove and the second limiting groove communicate with each other. A limiting block is connected to the periphery of the mounting rod, with the length direction of the limiting block aligned with the length direction of the mounting rod. The limiting block slides within the first limiting groove and the second limiting groove along its length.

[0022] By adopting the above technical solution, when in use, the limiting block is embedded in the first limiting groove and the second limiting groove, so that the scraper and the moving rod rotate stably in a predetermined direction.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During use, the lubricating oil in the oil storage tank is discharged from the oil storage tank through the grease outlet pipe. The rotating part drives the scraper to rotate, which makes the scraper stir the lubricating oil, speeding up the rate at which the lubricating oil is discharged from the oil storage tank and increasing the amount of oil discharged from the oil storage tank.

[0025] 2. During use, the rotating part drives the scraper to rotate. When the scraper agitates the lubricating oil, the auxiliary plate comes into contact with the lubricating oil. Under the guidance of the auxiliary plate, the auxiliary plate pushes the lubricating oil closer to the bottom of the oil storage tank, thereby further accelerating the discharge of lubricating oil from the oil storage tank, increasing the discharge volume of the oil storage tank, and improving the lubrication effect.

[0026] 3. After prolonged use, lubricating oil may adhere to the surface of the scraper. When the oil storage tank stores different types of oil, the surface of the scraper needs to be cleaned. The scraper is detachably connected to the connecting rod by bolts, which facilitates cleaning or replacement of the scraper. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses an electric lubrication pump. (Refer to...) Figure 1 and Figure 2 An electric lubrication pump includes a base 100 and an oil reservoir 200 connected to the base 100. The oil reservoir 200 is connected to the top of the base 100 and is vertically arranged. The oil reservoir 200 is connected to a grease return pipe 210 and a grease outlet pipe 220.

[0039] Reference Figure 1 and Figure 3 A scraper 300 is rotatably connected inside the oil storage tank 200. The axis of rotation of the scraper 300 is collinear with the central axis of the oil storage tank 200, and the length direction of the scraper 300 is consistent with the radial direction of the oil storage tank 200. The scraper 300 is located near the bottom of the oil storage tank 200, and a gap is provided between the bottom of the scraper 300 and the inner wall of the bottom of the oil storage tank 200. A rotating component is connected to the bottom of the scraper 300 and the base 100, which drives the scraper 300 to rotate. In use, the rotating component drives the scraper 300 to rotate, and the scraper 300 agitates the lubricating oil, thereby accelerating the flow rate of the lubricating oil, speeding up the discharge of lubricating oil from the oil storage tank 200, increasing the discharge volume, and improving the lubrication effect.

[0040] Refer to 4 and Figure 5 The base 100 has an oil storage cavity 110, which is connected to the oil storage tank 200. The bottom of the oil storage tank 200 has an oil drain port 260, which connects the oil storage tank 200 and the oil storage cavity 110. The base 100 also has a flow channel 120, one end of which is connected to the oil storage cavity 110, and the other end of which is connected to a grease outlet pipe 220. The grease outlet pipe 220 is connected to the base 100.

[0041] Reference Figure 1 The oil storage tank 200 has an opening at the top, and a mounting cover 230 is connected to the top of the oil storage tank 200. The mounting cover 230 covers the opening at the top of the oil storage tank 200 and is used to seal the opening. One end of the mounting cover 230 is rotatably connected to the oil storage tank 200, and the other end of the mounting cover 230 is detachably connected to the oil storage tank 200. A handle 231 is connected to the top of the mounting cover 230.

[0042] Reference Figure 1 and Figure 3A support block 240 is connected to the inner wall of the oil storage tank 200. The length of the support block 240 is aligned with the vertical direction, and the width of the support block 240 is aligned with the radial direction of the oil storage tank 200. The support block 240 is located near the bottom of the oil storage tank 200, and a liquid level detector is connected to the bottom of the support block 240. The liquid level detector is a photoelectric sensor 250. The photoelectric sensor 250 is electrically connected to a controller, and the controller is electrically connected to an indicator light 130, which is connected to the base 100. The photoelectric sensor 250 is used to detect the distance between the lubricating oil level in the oil storage tank 200 and the photoelectric sensor 250 and outputs the distance value. The controller is used to receive the distance value and calculate the liquid level value based on the distance value. When the controller receives the distance value, the controller controls the indicator light 130 to light up. The photoelectric sensor 250 is an IPF photoelectric sensor KN340107, and the controller is a PLC.

[0043] When the photoelectric sensor 250 detects the distance between the lubricating oil level and the photoelectric sensor 250 and outputs the distance value, the controller receives the distance value and controls the indicator light 130 to light up, thereby prompting the operator to add lubricating oil to the oil storage tank 200 in a timely manner.

[0044] Reference Figure 3 and Figure 4 The rotating component is a first motor 140, which is connected to the base 100. A connecting rod 141 is connected to the top of the output shaft of the first motor 140. The length of the connecting rod 141 is aligned with the vertical direction. The connecting rod 141 passes vertically through the inner wall of the bottom of the oil storage tank 200. The central axis of the output shaft of the first motor 140 is collinear with the central axis of the connecting rod 141, and the central axis of the connecting rod 141 is also collinear with the central axis of the oil storage tank 200. A scraper 300 is detachably connected to the connecting rod 141 by bolts. The bolts pass vertically through the scraper 300 and are threaded onto the connecting rod 141.

[0045] Reference Figure 1 and Figure 5 An auxiliary plate 310 is connected to one side of the scraper 300 along its width direction. The length direction of the auxiliary plate 310 is the same as that of the scraper 300. One end of the auxiliary plate 310 is connected to the scraper 300 along its width direction, and the other end of the auxiliary plate 310 is inclined away from the bottom of the oil storage tank 200. The scraper 300 is detachably connected to the connecting rod 141 for easy cleaning and replacement. With the addition of the auxiliary plate 310, when the scraper 300 rotates, the auxiliary plate 310 rotates with the scraper 300. Guided by the auxiliary plate 310, the auxiliary plate 310 pushes the lubricating oil closer to the bottom of the oil storage tank 200, thereby increasing the oil discharge volume.

[0046] The implementation principle of this application embodiment is as follows: In use, the first motor 140 drives the scraper 300 to rotate. The rotation of the scraper 300 causes the scraper 300 to stir the lubricating oil, thereby accelerating the flow rate of the lubricating oil. When the scraper 300 rotates, the auxiliary plate 310 rotates with the scraper 300. The auxiliary plate 310 pushes the lubricating oil closer to the bottom of the oil storage tank 200, thereby further accelerating the speed at which the lubricating oil is discharged from the oil storage tank 200, further increasing the oil discharge volume, and improving the lubrication effect.

In use, the cylinder 232 is fitted onto the top of the moving rod 320.

The moving rod 320 is moved vertically. When the moving rod 320 moves vertically and away from the oil storage tank 200, the scraper 300 moves with the moving rod 320, so that the scraper 300 is away from the oil storage tank 200, thereby facilitating the cleaning and replacement of the scraper 300.
