The present invention relates to a multi-purpose grease barrel pump with an easily adjustable discharge amount as a grease residue prevention-type pump inside a grease container, which has an (on / off) controllable pump flow rate, a function of spraying grease, a function of injecting very small amounts of grease periodically or continuously, and a function of pumping conventional large amounts of grease.

Description

A grease barrel pump with variable spray and grease discharge as a grease residual prevention pump.

[0001] The present invention relates to a multipurpose grease barrel pump that is a grease residual amount prevention type pump inside a grease barrel and is easy to control the discharge amount, and more specifically, to a multipurpose grease barrel pump that is 1) based on a grease residual amount prevention type, 2) has a branch and shock prevention structure, 3) has a pump flow rate control (on / off), 4) has a grease spray function, and 5) has a very small amount of grease discharge function and a large amount of grease discharge function.

[0002]

[0003] Typically, a barrel pump with a full-feeder exchange system replaces the grease container when it cannot discharge all the grease remaining in the container, or refills the grease according to the lower level alarm of the grease level gauge.

[0004] In this case, a significant amount of grease remains in the grease can, making it difficult to dispose of the remaining grease when replacing the can. If care is not taken, foreign substances may be inserted into the grease, making it unusable, and this may cause environmental pollution.

[0005] Therefore, in the case of a pump with a grease barrel exchange method, if the grease inside the barrel is completely used up and the grease barrel is replaced, lubrication can always be provided with new grease, so the grease specifications at the time of manufacture can be maintained and supplied.

[0006] In this regard, the applicant of the present invention has published in Korean Patent Publication No. 10-2023-0067147 (published on May 16, 2023) a “composite function grease level follower type electric grease barrel pump and its piping structure”, which comprises: a follower plate floating on the upper surface of grease contained in a grease barrel; a driving unit coupled to the follower plate; a pumping unit formed on the follower plate and discharging grease; and an agitator installed under the follower plate and pushing grease into a grease suction port; wherein the pumping unit comprises: first and second pumping spaces formed adjacent to the driving unit; first and second grease suction ports extending from the lower surface of the follower plate to the first and second pumping spaces; first and second check valves coupled to the first and second pumping spaces; And it relates to a multi-function grease level follower type electric grease barrel pump, characterized in that it comprises first and second pump elements coupled to the driving unit and reciprocating within the first and second pumping spaces, and a grease recovery port is formed in at least one of the first and second pumping spaces.

[0007] however,

[0008] 1) The above conventional "composite function grease level follower type electric grease barrel pump and its piping structure" has difficulty in sucking up all the grease remaining at the bottom of the grease barrel, so a new type of grease barrel pump was developed through improvement of this.

[0009] 2) The above conventional "composite function grease level follower type electric grease barrel pump and its piping structure and control function

[0010] (1) It only has a grease pump injection function, but it cannot widely apply a small amount of grease to a large area of ​​the wetted surface (boom) required for special equipment such as cranes.

[0011] (2) Due to the nature of the equipment, such as the hydraulic breaker, there was no function to continuously and periodically inject very small amounts of grease.

[0048]

[0049] Hereinafter, with reference to the attached drawings, a grease barrel pump with variable spray and grease discharge volume as a grease residual prevention pump according to the present invention will be described in detail.

This is a cross-sectional view of a follower plate of a barrel pump, and FIG. 8 is an example of use of a grease barrel pump with variable spray and grease discharge amount as a grease residual prevention pump according to an embodiment of the present invention.

[0051]

[0052] A grease barrel pump with variable spray and grease discharge amount as a grease residual prevention pump according to the present invention, as illustrated in FIG. 8, includes: a main plate (100) mounted on the upper part of a grease container (GC); a main cylinder (200) extending downwardly in communication from the main plate (100); a follower plate (300) that moves up and down on the outer periphery of the main cylinder (200); and a power unit (400) formed on the upper part of the main plate (100) and transmitting power into the main cylinder (200). Meanwhile, the pump according to the present invention may further include a protective cover (600), a support (700), a holder (800), and a grease container protection case (900).

[0053]

[0054] The above main plate (100) is configured to be mounted on the upper portion of the grease container (GC) and can be fixed or released from the upper outer periphery of the grease container (GC). As illustrated in FIGS. 1 and 2, the main plate (100) can be largely composed of a main plate-cover portion (110) and a main plate-grease container protection cover (120) extending downward from the outer periphery of the main plate-cover portion (110).

[0055] The main plate (100) may be formed integrally with the main plate-cover portion (110) and the main plate-grease container protection cover (120). The main plate-grease container protection cover (120) extends downward from the edge of the main plate-cover portion (110) by a certain section, and the main plate-grease container protection cover (120) extending downward by a certain section can be brought into close contact with the grease container at different heights. A fastening portion (122) may be formed on the main plate-grease container protection cover (120).

[0056] Meanwhile, the main plate (100) may be formed in two stages with the main plate-grease tank protection cover (120) in a stepped manner, and a grease tank pressurizing portion (120A) may be formed on the upper side, and a grease tank protection case pressurizing portion (120B) may be formed on the lower side. At this time, the grease tank pressurizing portion (120A) may pressurize the grease tank (GC), and the grease tank protection case pressurizing portion (120B) may strongly pressurize the grease tank protection case (900).

[0057]

[0058] The above main cylinder (200) is configured to extend downwardly from the main plate (100). At this time, the main cylinder (200), as illustrated in FIGS. 3 to 5, may include a body check (210) coupled to an end of the main cylinder (200) and an inlet piston (220) reciprocating within the body check (210). In addition, the main cylinder (200) may be fixed to the main plate (100) via a main cylinder tube holder (240) formed at the upper portion.

[0059] The above body check (210) is preferably coupled to the lower end of the main cylinder (200). The body check (210) is preferably inserted and coupled into the inside of the main cylinder (200) and extends upwards by a certain section. The body check (210) may be composed of two bodies, a first body check (210A) and a second body check (210B), but may also be configured as an integral body. The inside of the body check (210) is provided with a configuration in which the inlet piston (220) can move up and down reciprocally.

[0060] The body check (210) may have a body check cone-shaped inner wall (212). At this time, the space surrounded by the body check cone-shaped inner wall (212) may be referred to as a body check cone-shaped space (212S). The body check cone-shaped space (212S) preferably has a cone shape. The body check cone-shaped space (212S) is connected to a through space in the body check (210), and through this, the grease compressed in the body check cone-shaped space (212S) can be transferred upward. The body check (210) has a lower section inner circumference having a wider diameter than the outer circumference of the inlet piston (220), so that, at the initial stage of grease introduction, the grease is transferred upward through the space between the lower inner circumference of the body check (210) and the outer circumference of the inlet piston (220). At this time, a flow check (200f) that functions as a check valve may be formed between the lower inner circumference of the body check (210) and the outer circumference of the inlet piston (220). Meanwhile, a hole is formed at a certain height of the inlet piston (220), so that grease is transferred into the inlet piston (220), and the inner circumference of the upper section of the body check (210) is then brought into contact with the outer circumference of the inlet piston (220).

[0061] The above inlet piston (220) is coupled to a cam (440) and reciprocates up and down, and is configured to be inserted into a through space of a body check (210) and reciprocate within the body check (210). The inlet piston (220) penetrates the body check (210) up and down, and extends to the lower outer side of the body check (210) and is exposed. The inlet piston (220) may be composed of two bodies, a first inlet piston (220A) and a second inlet piston (220B), but may also be composed integrally.

[0062] A conical input valve (222) is formed at the end of the inlet piston (220). The conical input valve (222) has a shape corresponding to the body check conical space (212S), but is preferably a cone that is relatively smaller than the body check conical space (212S). The conical input valve (222) may be composed of a lower cylindrical body portion and an upper frusto-conical body portion extending upward from the cylindrical body portion, and the diameter of the lower surface of the frusto-conical body portion may be relatively smaller than the diameter of the cylindrical body portion. Through this, when the inlet piston (220) moves up and down with respect to the body check (210), the body check conical inner wall (212) and the conical input valve (222) can maintain a certain distance.

[0063] Meanwhile, four main cylinder-grease suction ports (230) may be formed on the lower outer periphery of the main cylinder (200). In addition, a main cylinder-filter (231) may be formed to surround the outer periphery where the main cylinder-grease suction ports (230) are formed. The main cylinder-grease suction port (230) is configured to allow grease to flow into the inside of the main cylinder (200), and the main cylinder-filter (231) is configured to prevent foreign substances from flowing into the main cylinder-grease suction port (230). The main cylinder-grease suction port (230) is formed to penetrate laterally, so that grease collected in a cone shape in the follower plate-protrusion space (320S) can be easily suctioned.

[0064] Meanwhile, as shown in FIGS. 4 and 5, the grease pumping operation structure within the main cylinder (200) is such that, first, pure grease is filtered by the main cylinder-filter (231) and moves into the internal space of the main cylinder (200) through the main cylinder-grease inlet (230). At this time, as the inlet piston (220) moves upward by the cam (440), the input valve (222) coupled to the lower portion of the inlet piston (220) also moves upward. Then, when the input valve (222) moves upward by a certain section, it is introduced into the body check cone-shaped space (212S), and the grease is compressed between the input valve (222) and the body check cone-shaped inner wall (212). At this time, the compressed grease is transported along the internal space of the body check (210) by the compressing force. At this time, the grease is initially transferred to the space between the inner periphery of the body check (210) and the outer periphery of the inlet piston (220). When the grease is transferred to a certain height, it flows into the inner periphery of the inlet piston (220) through a hole formed in the inlet piston (220), and is then transferred upward along the inner periphery of the inlet piston (220). Meanwhile, a check valve or the like may be installed inside the inlet piston (220) to prevent backflow.

[0065] In summary, the pump according to the present invention has a main cylinder (200) having a structure that compresses a certain amount of grease regardless of the piston stroke distance, thereby always compressing the grease discharge amount in proportion to the compression distance of the piston, thereby preventing any residual grease from remaining inside the piston, and by installing a main cylinder-filter (231) on the side of the main cylinder-grease suction port (230), it fundamentally prevents the inhalation of foreign substances and ensures that only pure grease is inhaled. In addition, the pump according to the present invention has a structure that can improve the grease suction power and discharge pressure through each conical configuration in the main cylinder (200).

[0066]

[0067] The above follower plate (300) is configured to move up and down on the outer periphery of the main cylinder (200). As illustrated in FIGS. 6 and 7, the follower plate (300) includes a follower plate-flat portion (310) and a follower plate-protrusion portion (320) that protrudes upward in a vertical shape from the center of the follower plate-flat portion (310).

[0068] A follower plate seal (311) may be formed on the outer periphery of the follower plate (300). Preferably, the follower plate seal (311) is formed on the outer edge of the follower plate-plane portion (310). Preferably, the follower plate seal (311) is formed of a soft rubber plate material. The follower plate seal (311) is in contact with the inner periphery of the grease container (GC) when the pump according to the present invention is coupled to the grease container (GC), and is a seal that constantly blocks the inflow of air between the upper section and the lower section of the follower plate (300). Through this, it has a structure in which air pockets cannot be generated in the grease inside the grease container.

[0069] A follower plate-weight (312) is formed on the upper portion of the follower plate (300), so as to pressurize the follower plate (300) with a constant weight. It is preferable that the follower plate-weight (312) be formed in a ring shape so as to uniformly apply weight to the entire surface of the follower plate (300).

[0070] The follower plate (300) may be provided with a follower plate-air vent (313). The follower plate-air vent (313) may have a structure capable of immediately removing air when an air pocket is generated. At this time, if the grease is not discharged due to an air pocket remaining inside the grease, the air pocket can be simply removed instantly through the follower plate-air vent (313). In addition, the follower plate-air vent (313) enables the follower plate (300) to be easily replaced when exchanging the follower plate (300) from one grease container (GC) to another grease container (GC).

[0071] A follower plate-protrusion space (320S) is formed within the above follower plate-protrusion space (320S). The follower plate-protrusion space (320S) is formed at the center of the follower plate (300). The pump according to the present invention collects grease in a cone shape through the space, and sucks the grease laterally through the main cylinder-grease suction port (230) formed at the lower outer periphery of the main cylinder (200), thereby allowing the grease to be sucked in completely from the center of the grease container (GC).

[0072] A follower seal (330) is coupled to the follower plate-protrusion (320). The follower seal (330) is configured to be coupled to the outer periphery of the main cylinder (200), and is preferably formed in a ring shape. At this time, it is appropriate to have an inner periphery of the follower seal (330) with a size corresponding to the outer periphery of the main cylinder (200), so that the follower seal (330) can move up and down while in close contact with the main cylinder (200). Meanwhile, the follower seal (330) may be coupled by protruding further upward than the follower plate-protrusion (320).

[0073] In summary, the pump according to the present invention installs the follower plate (300) that blocks the grease contact surface and air inflow inside the grease container, and installs a weight (312) having a certain weight or more on the upper part of the follower plate (300) so that the size of the air pocket remaining inside the grease does not increase beyond a certain level when the pump according to the present invention sucks up grease, and continuously pushes the lower part. Meanwhile, a follower plate seal (311) is formed with a very thin and soft rubber plate on the end edge of the follower plate (300). The pump according to the present invention continuously blocks air inflow by specially manufacturing and installing the follower plate seal (311) that constantly blocks air inflow regardless of the difference in the circumference size of the upper and lower parts of the grease container (GC). The pump according to the present invention performs a sealing function regardless of the difference in the inner diameter of the upper and lower parts of the grease container based on the follower plate (300) through the follower plate seal (311).

[0074]

[0075] The above power unit (400) is formed on the upper portion of the main plate (100) and is configured to transmit power into the main cylinder (200). The above power unit (400) includes a power unit fixing member (410), a motor (420), a gear member (430), and a cam (440).

[0076] The above power unit fixing member (410) is configured to fix the power unit (400) to the main plate (100). The motor (420) receives power from an external source to generate power, and can transmit it to the gear unit (430). The gear unit (430) transmits the power received from the motor (420) to the cam (440).

[0077] The cam (440) above converts the rotational force received from the motor (420) into an up-and-down reciprocating motion and transmits it into the main cylinder (200). More specifically, the cam (440) is coupled with the inlet piston (220) and allows the inlet piston (220) to move up and down.

[0078]

[0079] Meanwhile, the pump according to the present invention may further include a distribution control unit (500) formed on the upper portion of the main plate (100) to distribute grease discharged from the main cylinder (200) and control the equipment.

[0080] A grease barrel pump with variable spray and grease discharge volume as a grease residual prevention pump according to the present invention may further include a distribution control unit (500) having two discharge ports with different discharge volumes. In this case, the two discharge ports may be a high-flow discharge port (540) and a low-flow discharge port (550) or a grease spray discharge port.

[0081] The above distribution control unit (500) includes a distribution unit (510). A distributor (511) may be coupled to the distribution unit (510). When the pump is operated above a preset pressure, the distribution control unit (500) may allow grease inside the pipe of the distribution control unit (500) to be recovered into the follower plate (300). The distribution unit (510) may be connected to a component such as a lever (560) or a switch (551) in a wired or wireless manner. The distribution unit (510) may also control the discharge amount transferred to the high-flow discharge port (540) and the low-flow discharge port (550).

[0082] A flow path (520) may be formed on the upper portion of the distribution unit (510). A flow meter (521) is installed in the flow path (520) of the distribution control unit (500), so that when a flow rate exceeds or falls below a certain amount, the user can control the grease flow through the distribution control unit (500). While a typical flow meter only calculates the flow rate (volume metering), the flow meter (521) according to the present invention can check the (total discharge amount) / (number of operations or operating time) set in the distribution control unit (500). Here, the discharge amount set is the flow rate that should be discharged from the entire pump. When a control function is set in the flow meter (521) to cause a flow rate exceeding or falling below the (discharge amount) / (number of operations or operating time) set in the distribution control unit (500), the controller of the grease injection system is immediately brought to an emergency stop, so that the entire system can be protected. At this time, by preemptively maintaining the above distribution points or lubrication points, it is possible to prevent major equipment accidents, minimize grease loss due to pipe damage, and maintain an appropriate lubrication state at all times.

[0083] A three-way valve (530) is connected to the upper portion of the above-mentioned flow path (520). A high-flow discharge port (540) and a low-flow discharge port (550) are connected to the three-way valve (530), so that different amounts of grease can be transferred to different locations. In addition, a grease discharge function can be selected.

[0084] Meanwhile, a switch (551) may be formed in the low-flow discharge port (550). In addition, a switch button (552) may be formed in the switch (551). The switch is an LM s / w and has a function of controlling the discharge amount between the high-flow discharge port (540) and the low-flow discharge port (550). Accordingly, the switch may be connected to a specific application of an external device, and may control the discharge amount of grease discharged through the high-flow discharge port (540) and the low-flow discharge port (550) with a value preset in the application. In addition, a grease spray function may be selected.

[0085] At this time, a lever (560) is formed in the three-way valve (530) so that the user can control the movement of the grease. The lever (560) is configured to change the grease discharge direction by rotating it. The lever (560) can also directly control the grease discharge direction, discharge amount, or spray function for the high-flow discharge port (540) and the low-flow discharge port (550) by adjusting the pipe within the three-way valve (530).

[0086] Meanwhile, a lever extension member (561) may be formed on the lever (560), and the lever extension member (561) moves away from or releases the switch button (552) of the switch (551) when the lever (560) is rotated, thereby allowing the switch button (552) of the switch (551) to be operated. The lever extension member (561) operates the switch button (552) of the switch (551), i.e., the LM s / w, according to the rotation angle, thereby allowing the mode of the controller to be changed simultaneously.

[0087] In a multi-function grease pump, a high-pressure electric directional control valve is usually used to change the direction or open / close the grease discharge port. However, the pump according to the present invention, through a configuration of a flow meter (521), a lever (560), a lever extension member (561), a switch (551), a switch button (552), etc., enables visual control more cheaply and reliably, and eliminates the need for re-inspection and reduces production costs. Therefore, by operating the lever (560), the grease discharge direction or discharge amount can be changed, and when a certain rotation angle is reached, the switch button (552) of the switch (551) can be operated to change the control mode of the grease injection controller.

[0088]

[0089] Meanwhile, the present invention may be provided with additional components as shown in FIGS. 8 to 10, in addition to the grease barrel pump with variable spray and grease discharge volume as the grease residual prevention pump.

[0090] First, the pump according to the present invention may include a protective cover (600) that covers the power unit (400) and the distribution control unit (500) from the outside. The protective cover (600) has a lever (560) exposed to the outside, and a high-flow discharge port (540) and a low-flow discharge port (550) exposed to the outside. Meanwhile, a portion of the distribution unit (510) is also exposed to the outside. Meanwhile, a controller (610) may be formed on one side of the protective cover (600), and a handle (620) may be formed on the upper side.

[0091] Meanwhile, the pump according to the present invention may include a support (700), a stand (800) extending upward from one side of the support (700), and a grease protection case (900) coupled to the upper portion of the support (700).

[0092] It is preferable that the above-mentioned support member (700) has a rectangular shape. At this time, a stand (800) extends upward from the support member (700), and the stand (800) may include two pillars and a crescent-shaped stand (810) formed on the upper portions of both pillars.

[0093] The above grease protection case (900) is mounted on the support (700). A grease protection case-fastening part (910) may be formed on the outer periphery of the grease protection case. At this time, a main plate-fastening part (124) may be formed on the outer periphery of the main plate (100), and the grease protection case-fastening part (910) formed on the grease protection case (900) and the main plate-fastening part (124) may be mutually coupled to be strongly fixed to each other.

[0094] When the pump according to the present invention is simply placed on top of a grease tank (GC), the bonding force is weak and sufficient pressure is not applied. Therefore, the grease tank (GC) is accommodated in a grease tank protection case (900), and the upper and lower portions of the grease tank protection case (900) and the main plate (100) are pressurized and fixed to prevent the grease tank (GC) from flowing. At this time, the grease tank pressurizing part (120A) pressurizes and fixes the grease tank, and the grease tank protection case pressurizing part (120B) pressurizes and fixes the grease tank protection case (900), so that each component can be individually fixed.

[0095] The above grease tank protection case (900) may be provided with a window having a structure that allows for visual identification of the grease level. In this case, if the grease tank (GC) accommodated in the grease tank protection case (900) is made of a transparent material, the level of the grease can be visually identified through the window of the grease tank protection case (900).

[0096]

[0097] The pump according to the present invention can be applied to both fixed and mobile pumps, and the discharge amount and pressure of the pump are always relative to other discharge ports, with a high discharge amount - low discharge pressure, and a low discharge amount - high discharge amount. It is applicable to all equipment having different lubricant injection amounts and injection cycles, and is economical.

[0098] That is, the pump according to the present invention can be applied to concrete pump cars, cranes and cargo cranes, excavators and various equipment attached thereto (brakers and attachments, etc.), rock drill machines, and other special machinery equipment (construction and mining equipment, etc.) having different lubricant injection amounts and injection cycles. In addition, for equipment having square or cylindrical sliding booms with different sizes for each stage, such as cranes, it is difficult to apply grease because the sizes and areas of the sliding surfaces are each different, but if the pump according to the present invention is selected and used with a spray function, it is very economical.

[0099] The amount of grease discharge is automatically controlled by the controller by selecting the rotation speed of the driving unit (400).

[0100] If the main cylinder (200) connected to the grease pump main plate (100) acts as a stand during a grease tank replacement, a major problem may occur due to foreign matter attachment. Therefore, the crescent-shaped stand (810) on the back of the grease tank protection case (900) performs this function.

[0101] The pump according to the present invention 1) has two discharge ports, a high-flow discharge port (540) and a low-flow discharge port (550), 2) a grease tank pressurizing part (120A) and a grease tank protection case pressurizing part (120B) are formed vertically on the pump main plate (100) to pressurize the grease tank (GC) and the grease tank protection case (900), respectively, 3) has a main plate-fastening part (124) and a grease tank protection case-fastening part (910) that mutually fasten the pump main plate (100) and the grease tank protection case (900), 4) the pump controller can be attached to or separated from the pump main plate, 5) the grease tank protection case (900) and the main frame are not always integral with the pump, but can be applied in a separate combination as needed, and 6) the grease spray function is generally used with a spray gun and The nozzle must be attached.

[0102] The pump according to the present invention relates to a grease barrel pump having 1) a very small amount of grease injection function - a grease barrel pump dedicated to a breaker (small amount of grease discharge) 2) a centralized progressive grease injection system (slightly small amount of grease discharge) 3) a conventional grease discharge amount using a grease gun, such as a classic manual grease injector, a single-type automatic grease injector pump, or a double-pipe automatic grease injector (double-pipe, single-pipe, or gun-type) 4) a grease spray function dedicated to boom cranes and wire rope cranes (dedicated to boom cranes and rope cranes) 5) a large amount of grease discharge, such as a pump used when replenishing grease in a refillable grease barrel of an existing centralized system (widely applied at present) and a barrel-replaceable grease barrel pump. The above functions may be performed through the configuration of a controller (610) and a distribution control unit (500), etc.

[0103] According to the present invention, a grease barrel pump with variable spray and grease discharge volume as a grease residual prevention pump is characterized in that, when the function of the grease pump is selected by a pump controller signal or a manual lever for selecting the function of the equipment as a grease residual prevention pump, 1) a very small amount of grease is periodically or continuously injected into a breaker only when the breaker is operated. In addition, according to the present invention, a grease barrel pump with variable spray and grease discharge volume as a grease residual prevention pump is characterized in that, when the function of the grease pump is selected by a pump controller signal or a manual lever for selecting the function of the equipment as a grease residual prevention pump, 1) a very small amount of grease is periodically or continuously injected into a crane only when the breaker is operated.

[0104] As for the grease pump type, as seen above, a refill type system pump is usually used, but after using the grease, replenishing the grease to the central system refill type pump 1) takes a lot of time if you don't have a special grease injector, if you inject it with a manual gun or air grease pump, 2) if you use a large grease pump to reduce the time and cost of refilling grease, not only is the cost excessive, but there are very few grease pumps that meet the conditions, so it is almost impossible to use, 3) if you use a barrel exchange type pump, you can dramatically save time and cost by replacing the commercially available grease canister when all the grease is used up, and 4) since the grease injection method and injection amount vary depending on the type of equipment, it is impossible to solve the problem with a grease pump with a single simple function, 5) heavy equipment usually moves long and short distances and usually has one main function and a main function driving function, so it requires a different grease injection system, but there is no grease pump system with this structure on the market, 6) we are continuously developing a pump with a complex function structure and patenting it.

[0105] Accordingly, the present invention is to develop a multipurpose grease barrel pump which is composed of a main plate, a main cylinder, and a follower plate that moves up and down on the outer periphery of the main cylinder, and is a pump with a branch and shock-proof structure based on a grease residual prevention type, and which is capable of controlling the pump flow rate (on / off), and which has a grease spray function, a function for periodically or continuously injecting a very small amount of grease, and a function for discharging a large amount of grease as a conventional grease pump, and which is a grease residual prevention type pump inside a grease barrel, and which is easy to control the discharge amount.
