Description

Technical Field

[0001] This utility model relates to a self-filling electric grease filling component adapted to a standard grease container. Background Technology

[0002] In the field of construction machinery, the working parts of construction machinery are in direct contact with materials. If a centralized lubrication system is installed, the lubrication pipelines and distributors of the centralized lubrication system are often easily damaged by the impact of the materials, which affects the overall operation of the lubrication system. Therefore, the working parts of construction machinery (actuators, such as the lubrication of the connecting rod corresponding to the bucket of an excavator) are generally lubricated manually. For ease of operation, electric grease guns are often used.

[0003] However, the capacity of electric handheld grease guns is very limited. For medium, large, and super-large construction machinery, one grease gun is far from enough, and grease needs to be replenished into the grease reservoir multiple times. The existing method generally uses a piston structure, similar to the structure of a medical syringe. The hand-held lever pulls the piston to draw grease from the standard grease container. Since grease is a semi-fluid, its flowability is extremely poor. This process is very laborious and time-consuming. Moreover, due to the harsh on-site environment and improper operation by personnel, impurities often fall into the grease container during manual grease replenishment, contaminating the grease and affecting its lubricating performance. Utility Model Content

[0004] The purpose of this invention is to provide a self-filling electric grease filling component that is compatible with standard grease containers. It can be directly adapted to standard grease containers. The follow-up power suction cup sinks into the grease container and forms a sealed structure with the container wall. Then, the electric grease gun rotates forward to drive the follow-up power suction cup to draw grease from the grease container and fill the grease reservoir of the electric grease gun. This achieves a rapid self-filling effect, significantly improves grease filling efficiency, and makes the grease filling process easier and less labor-intensive. In addition, the follow-up power suction cup has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

[0005] The technical solution of this utility model for a self-filling electric grease filling assembly for standard grease tanks is as follows: The self-filling electric grease filling assembly for standard grease tanks includes:

[0006] A follow-up power suction cup is used to sink into a standard grease container and extract grease. The follow-up power suction cup adheres to the grease surface of the container and descends with the grease level. It includes a container body, a sealing rubber ring, a central suction tube, a suction auger, and a worm gear mechanism. The sealing rubber ring is located on the outer periphery of the container and has an elastic deformable portion for a sliding seal against the container wall. The central suction tube has a cap at its top and is located at the center of the container body. The lower end of the central suction tube connects to the bottom of the container to form a grease inlet. The upper side of the central liposuction cannula has a liposuction outlet, and a first quick-connect cannula connector is connected to the liposuction outlet. A liposuction auger is rotatably assembled inside the central liposuction cannula. The liposuction auger includes a central rotating shaft and spiral conveying blades spirally arranged around it. The outer diameter of the spiral conveying blades is the same as the inner diameter of the central liposuction cannula. The upper end of the central rotating shaft passes through the cap and extends outward. The upper end of the central rotating shaft is rotatably sealed with the cap. The worm gear mechanism includes a worm wheel and a worm that are in a transmission engagement. The worm wheel is rotatably mounted on the upper end of the central rotating shaft. One end of the worm has a first transmission quick-connect cannula connector.

[0007] An electric grease gun includes a grease reservoir, a drive motor, a ratchet mechanism, and a grease dispensing plunger assembly. The grease reservoir has a grease inlet, and a second quick-connect fitting is connected to the inlet via a grease hose. The drive motor includes a motor output shaft, and the outer end of the motor output shaft is equipped with a second quick-connect fitting. The first and second quick-connect fittings can be quickly inserted and engaged to achieve mutual transmission. The ratchet mechanism is installed in the middle of the motor output shaft and includes an inner wheel, a pawl, and an outer wheel. The inner wheel is fixedly connected to the motor output shaft, and the pawl is rotatably mounted on the inner wheel. The outer wheel has an eccentrically positioned inner circular hole, and the inner circumference of the inner circular hole is... It has ratchet teeth and a pawl that engage with the ratchet teeth in a one-way transmission. When the motor output shaft reverses, the inner wheel drives the outer wheel to rotate through the pawl. The inner and outer wheels form an eccentric wheel mechanism. The grease discharge plunger pair is driven by the eccentric wheel mechanism to pressurize and pump the grease in the grease reservoir out. When the motor output shaft rotates forward, the first quick-connect fitting and the second quick-connect fitting are inserted and engaged. The pawl and ratchet teeth disengage, and the second quick-connect fitting of the motor output shaft can be inserted into the first quick-connect fitting of the worm gear to drive the worm gear to rotate. The grease suction auger rotates accordingly, transporting the grease along the central grease suction tube to the grease reservoir.

[0008] The beneficial effects of this solution are as follows: During normal operation, the electric grease gun reverses the motor via a switch, causing the motor output shaft to reverse, which in turn drives the inner wheel to reverse. The pawl on the inner wheel meshes with the ratchet on the outer wheel, driving the outer wheel to reverse. The outer wheel, as part of the eccentric wheel mechanism, can drive the grease plunger to extract the grease from the grease reservoir and pump it out under high pressure to lubricate the lubrication points. When the grease reservoir needs replenishment, open the lid of the standard grease container, insert the follower-up power suction cup into the container until it contacts the grease, then connect the second quick-connect fitting of the electric grease gun to the first quick-connect fitting of the follower-up power suction cup, and align the second transmission quick-connect fitting of the electric grease gun with the first transmission quick-connect fitting of the follower-up power suction cup. Then, control the motor to rotate forward via the switch of the electric grease gun. At this time, due to the single structure of the ratchet and pawl... When the inner wheel engages with the outer wheel, the two disengage, meaning the inner wheel cannot transmit power to the outer wheel. The inner wheel spins freely with the motor output shaft, but the motor output shaft, through the transmission between the second and first transmission quick-connect joints, can drive the worm gear to rotate, which in turn drives the worm wheel and the central shaft to rotate, and the spiral conveying blades to rotate. Utilizing the conveying mechanism formed by the spiral conveying blades and the central suction tube, the grease in the grease tank is conveyed upwards. The grease sequentially passes through the grease inlet and outlet of the central suction tube, the first quick-connect joint, the second quick-connect joint, and the grease replenishment hose before entering the grease reservoir of the electric grease gun for rapid grease replenishment. As the grease in the standard grease tank is gradually sucked away, the liquid level gradually drops. Under the vacuum suction between the liquid level and the follow-up power suction cup, the follow-up power suction cup also descends with the drop in liquid level, ensuring that grease can be sucked up at all times. As can be seen from the above working process, this application can be directly adapted to a standard grease container. The follow-up power suction cup sinks into the grease container and forms a sealed structure with the container wall. Then, the electric grease gun rotates forward to drive the follow-up power suction cup to draw grease from the grease container and replenish it into the grease reservoir of the electric grease gun, achieving a rapid self-greasing effect. The grease replenishment efficiency is significantly improved, and the grease replenishment process is easier and less labor-intensive. In addition, the follow-up power suction cup has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

[0009] Furthermore, a scraping roller is provided at one end of the central shaft extending below the disc body. The scraping roller rotates with the central shaft to squeeze the grease toward the grease inlet of the central suction tube. The scraping roller ensures that the liposuction auger can easily draw up the grease, preventing the liposuction auger from running dry.

[0010] Furthermore, the scraping wheel includes three scraping blades, each blade being an arc-shaped structure bent in the direction of rotation. This structure of the scraping blades generates a centripetal driving force on the grease, causing it to move towards the grease inlet of the central suction tube.

[0011] Furthermore, the scraping blade is made of steel plate with a thickness of not less than 2mm.

[0012] Furthermore, the lower end of the spiral conveying blade extends from the lower opening of the central grease suction tube to guide the grease smoothly into the central grease suction tube.

[0013] Furthermore, the central rotating shaft is provided with two support bearings, each bearing including an inner ring, an outer ring, and a roller assembly. The inner ring is fitted onto and fixed on the central rotating shaft, while the outer ring is fixed to the inner wall of the central liposuction tube by at least three evenly distributed support rods.

[0014] Furthermore, the structure of the first transmission quick connector includes a cross-shaped boss and a positioning frustum spaced apart from the cross-shaped boss, and the structure of the second transmission quick connector includes a matching cross-shaped groove.

[0015] Furthermore, the outer diameter of the disc is not greater than the minimum inner diameter of the standard grease container, and the outer diameter of the sealing rubber ring is not less than the minimum inner diameter of the standard grease container.

[0016] Furthermore, the drive motor is a speed-regulating motor, and the forward and reverse rotation speeds of the drive motor can be adjusted separately via a switch to control the oil replenishment speed and oil output speed.

[0017] Furthermore, a fixed bracket is fixed to the outside of the central liposuction cannula, and the two ends of the worm gear are respectively rotatably assembled on the fixed bracket through bearings.

[0018] Furthermore, the electric grease gun includes a removable rechargeable battery.

[0019] Furthermore, the grease reservoir is equipped with a spring and a piston, and the grease filling port is located at the end away from the spring.

[0020] Furthermore, it includes a carrying case with a placement space inside that is adapted to the shape of the electric grease gun and the follow-up power suction cup.

[0021] Furthermore, the outer circumferential surface of the outer wheel is provided with an annular groove, and one end of the plunger of the grease outlet plunger assembly slides in the annular groove through a hook structure. Attached Figure Description

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0036] Specific embodiments of the self-filling electric grease filling assembly for standard grease tanks of this utility model are as follows: Figure 1-9 As shown, the self-filling electric grease dispenser assembly for standard grease containers mainly includes a follow-up power suction cup 2, an electric grease gun 3, and a carrying case. The carrying case has placement positions that are compatible with the shape of the electric grease gun 3 and the follow-up power suction cup 2.

[0037] like Figure 1As shown, the follow-up power suction cup 2 is used to sink into a standard grease container and extract grease from it. It includes a disc body 21, a sealing rubber ring 22, a central grease suction tube 23, a grease suction auger 24, and a worm gear mechanism 25. The sealing rubber ring 22 is located on the outer periphery of the disc body 21, and its outer periphery has an elastic deformation portion for sealing and sliding with the wall of the grease container. The top of the central grease suction tube 23 has a cap 231. The central grease suction tube 23 is located at the center of the disc body 21, and its lower end opening communicates with the lower part of the disc body 21 to form a grease inlet 232. The upper side of the central grease suction tube 23 has a grease outlet 233. A first quick-connect connector 234 is connected to the central liposuction cannula 23, and a liposuction auger 24 is rotatably mounted inside it. The liposuction auger 24 includes a central rotating shaft 241 and spirally arranged spiral conveying blades 242. The outer diameter of the spiral conveying blades 242 is the same as the inner diameter of the central liposuction cannula 23. The upper end of the central rotating shaft 241 extends outward after passing through the cap 231, and the upper end of the central rotating shaft 241 is rotatably sealed with the cap 231. The worm gear mechanism 252 includes a worm gear 251 and a worm 252 that are in a transmission engagement. The worm gear 251 is rotatably mounted on the upper end of the central rotating shaft 241, and one end of the worm 252 has a first transmission quick-connect connector 2521. The lower end of the spiral conveying blades 242 extends out from the lower opening of the central liposuction cannula 23 to guide the grease smoothly into the central liposuction cannula 23. Figure 1 , 3 As shown, a scraping roller 26 is provided at one end of the central rotating shaft 241 extending below the disc body 21. The scraping roller 26 rotates with the central rotating shaft 241 to squeeze the grease towards the grease inlet 232 of the central suction tube 23. The scraping roller 26 ensures that the grease suction auger 24 can easily suction the grease, preventing the grease suction auger 24 from emptying. The scraping roller 26 includes three scraping blades 261, which are arc-shaped structures bent in the direction of rotation. This structure of the scraping blades 261 can generate a centripetal driving force on the grease, causing the grease to move towards the grease inlet 232 of the central suction tube 23. The scraping blades 261 are made of steel plate with a thickness of not less than 2mm. Figure 1 , 2 As shown, the central rotating shaft 241 is equipped with two support bearings 27. Each support bearing 27 includes an inner ring 271, an outer ring 272, and a roller assembly 273. The inner ring 271 is fitted onto and fixed to the central rotating shaft 241, and the outer ring 272 is fixed to the inner wall of the central liposuction tube 23 by at least three evenly distributed support rods 274. The outer diameter of the disc body 21 is not greater than the minimum inner diameter of a standard grease container, and the outer diameter of the sealing rubber ring 22 is not less than the minimum inner diameter of a standard grease container. A fixed bracket is fixed to the outside of the central liposuction tube 23, and both ends of the worm gear 252 are rotatably mounted on the fixed bracket via bearings.

[0038] like Figure 6 , 9 As shown, the electric grease gun 3 includes a grease reservoir 31, a drive motor 32, a ratchet mechanism 33, and a grease dispensing plunger assembly 34. The grease reservoir 31 has a grease filling port 311, and a second quick-connect fitting is connected to the grease filling port 311 via a grease filling hose. The drive motor 32 includes a motor output shaft 321, and a second transmission quick-connect fitting 3211 is provided at the outer end of the motor output shaft 321. The first and second transmission quick-connect fittings 3211 can be quickly inserted and engaged to achieve mutual transmission. The ratchet mechanism 33 is installed in the middle of the motor output shaft 321. The ratchet mechanism 33 includes an inner wheel 331, a pawl 332, and an outer wheel 333. The inner wheel 331 is fixedly connected to the motor output shaft 321, and the pawl 332 is rotatably mounted on the inner wheel 331. The outer wheel 333 has an eccentrically set inner circular hole, and the inner circumferential surface of the inner circular hole is provided with... The ratchet 3331 and pawl 332 are engaged in a one-way transmission with the ratchet 3331. When the motor output shaft 321 reverses, the inner wheel 331 drives the outer wheel 333 to rotate through the pawl 332. The inner wheel 331 and the outer wheel 333 form an eccentric wheel mechanism. The grease discharge plunger pair 34 is driven by the eccentric wheel mechanism to pressurize and pump the grease in the grease reservoir 31 out. When the motor output shaft 321 rotates forward, the first quick-connect tube connector 234 is inserted into the second quick-connect tube connector, and the pawl 332 disengages from the ratchet 3331. The second transmission quick-connect tube connector 3211 of the motor output shaft 321 can be inserted into the first transmission quick-connect tube connector 2521 of the worm 252 to drive the worm 252 to rotate. The grease suction auger 24 rotates accordingly, transporting the grease along the central grease suction tube 23 into the grease reservoir 31. The drive motor 32 is a speed-regulating motor, and its forward and reverse rotation speeds can be adjusted via a switch to control the grease filling and dispensing speeds. The electric grease gun 3 includes a removable rechargeable battery 35. The grease reservoir 31 contains a spring 312 and a piston 313, and the grease filling port 311 is located at the end furthest from the spring 312. The outer circumferential surface of the outer wheel 333 has an annular groove 3332, and one end of the plunger of the grease dispensing plunger assembly 34 slides within the annular groove 3332 via a hook structure. Figure 5 , 7 As shown, the structure of the first transmission quick connector 2521 includes a cross-shaped boss 25211 and a positioning frustum 25212 spaced apart from the cross-shaped boss 25211. The structure of the second transmission quick connector head includes a matching cross-shaped groove 32111.

[0039] During normal operation, the electric grease gun 3 reverses the motor via a switch, causing the motor output shaft 321 to reverse, which in turn drives the inner wheel 331 to reverse. The pawl 332 on the inner wheel 331 meshes with the ratchet 3331 on the outer wheel 333, driving the outer wheel 333 to reverse. The outer wheel 333, as part of the eccentric wheel mechanism, can drive the grease plunger pair 34 to draw out the grease from the grease reservoir 31 and pump it out under high pressure to lubricate the lubrication points. When the grease reservoir 31 needs to be replenished, the lid of the standard grease container is opened, and the follow-up power suction... The disc 2 is inserted into the container from the opening until it contacts the grease. Then, the second quick-connect fitting of the electric grease gun 3 is connected to the first quick-connect fitting 234 of the follow-up power suction cup 2. The second transmission quick-connect fitting 3211 of the electric grease gun 3 is connected to the first transmission quick-connect fitting 2521 of the follow-up power suction cup 2. Then, the motor is controlled to rotate forward by the switch of the electric grease gun 3. At this time, since the ratchet 3331 and the pawl 332 have a one-way meshing structure, they disengage. That is, the inner wheel 331 cannot transmit power to the outer wheel 333. 1. The motor output shaft 321 rotates freely, but the motor output shaft 321, through the transmission between the second transmission quick connector 3211 and the first transmission quick connector 2521, can drive the worm gear 252 to rotate, which in turn drives the worm wheel 251 and the central rotating shaft 241 to rotate, thereby driving the spiral conveying blades 242 and the scraping wheel 26 to rotate. The scraping blades 261 of the scraping wheel 26 can generate a centripetal driving force on the grease, causing the grease to move towards the grease inlet 232 of the central grease suction tube 23 at the center. Then, the spiral conveying blades 242 and the central grease suction tube 23 are used to move the grease. The conveying mechanism formed by the tube 23 conveys the grease in the grease tank upwards. The grease passes sequentially through the grease inlet 232, grease outlet 233, first quick-connect tube connector 234, second quick-connect tube connector, and grease replenishment hose of the central grease suction tube 23 into the grease reservoir 31 of the electric grease gun 3 for rapid grease replenishment. As the grease in the standard grease tank is gradually sucked away, the liquid level will gradually drop. Under the vacuum suction between the liquid level and the follow-up power suction cup, the follow-up power suction cup also drops with the drop in liquid level, ensuring that grease can be sucked up at all times. As can be seen from the above working process, this application can be directly adapted to a standard grease container. The follow-up power suction cup 2 sinks into the grease container and forms a sealed structure with the container wall. Then, the electric grease gun 3 rotates forward to drive the follow-up power suction cup 2 to draw grease from the grease container and replenish it into the grease reservoir 31 of the electric grease gun 3. This achieves a rapid self-greasing effect, significantly improves grease replenishment efficiency, and makes the grease replenishment process easier and less labor-intensive. In addition, the follow-up power suction cup 2 has a protective effect on the grease in the grease container, preventing dust, debris, rainwater, etc. from falling into the grease container and contaminating the grease.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
