Description

Technical Field

[0001] The present invention relates to a sunken barrel self - replenishing grease electric greasing assembly adapted to a standard grease barrel. Background Art

[0002] In the field of construction machinery, since the working components of construction machinery are in direct contact with materials, if a centralized lubrication system is arranged, the lubrication pipelines and distributors of the centralized lubrication system are often easily damaged by being knocked and collided by materials, affecting the overall operation of the lubrication system. Therefore, the working components of construction machinery (actuators, such as the lubrication at the connecting rod corresponding to the bucket of an excavator) generally adopt manual lubrication methods, and in order to facilitate operation, an electric grease gun is often used.

[0003] However, the volume of the electric hand - held grease gun is very limited. For medium - sized, large - sized, and extra - large construction machinery, one shot of grease is far from enough, and it is necessary to replenish grease into the grease storage cylinder multiple times. The existing method generally adopts a piston structure, similar to the structure of a medical syringe. The hand - held pull rod is used to pull the piston to suck the lubricating grease from the standard grease barrel. Since the lubricating grease is a semi - fluid and has extremely poor fluidity, this process is very laborious and time - consuming. Moreover, due to the harsh on - site environment and improper operation of personnel, sundries often fall into the grease barrel during the manual grease replenishment process, contaminating the lubricating grease inside and affecting the lubricating performance of the lubricating grease. Summary of the Invention

[0004] The purpose of the present invention is to provide a sunken barrel self - replenishing grease electric greasing assembly adapted to a standard grease barrel, which can be directly adapted to the standard grease barrel, sink into the grease barrel through a follow - up power suction cup and form a sealed structure with the barrel wall, and then use the forward rotation of the electric grease gun to drive the follow - up power suction cup to suck the lubricating grease from the grease barrel and supplement it into the grease storage cylinder of the electric grease gun, achieving the effect of rapid self - replenishing grease, significantly improving the grease replenishing efficiency, making the grease replenishing process easier and more labor - saving, and the follow - up power suction cup has a protective effect on the lubricating grease in the grease barrel, preventing dust, sundries, rainwater, etc. from falling into the grease barrel to contaminate the lubricating grease.

[0005] The technical solution of the sunken barrel self - replenishing grease electric greasing assembly adapted to a standard grease barrel of the present invention is as follows: The sunken barrel self - replenishing grease electric greasing assembly adapted to a standard grease barrel includes:

[0006] The follow-up power suction cup is used to sink into a standard grease barrel and suck lubricating grease therefrom. The follow-up power suction cup fits with the grease liquid level of the standard grease barrel and descends as the liquid level drops. It includes a disc body, a sealing rubber ring, a central grease suction pipe, a grease suction auger, and a worm and worm gear mechanism. The sealing rubber ring is arranged on the outer periphery of the disc body. The outer periphery of the sealing rubber ring has an elastic deformation part for sealing and sliding cooperation with the barrel wall of the grease barrel. The top of the central grease suction pipe has a cover. The central grease suction pipe is arranged at the center of the disc body. The lower end opening of the central grease suction pipe communicates with the part below the disc body to form a grease inlet. One side of the upper part of the central grease suction pipe has a grease outlet, and a first quick plug-in joint is connected to the grease outlet. A grease suction auger is rotationally assembled in the central grease suction pipe. The grease suction auger includes a central rotating shaft and spiral conveying blades spirally arranged thereon. The outer diameter of the spiral conveying blades is the same as the inner diameter of the central grease suction pipe. The upper end of the central rotating shaft extends outwards after passing through the cover. The upper end of the central rotating shaft is rotationally and sealingly matched with the cover. The worm and worm gear mechanism includes a worm and a worm gear in transmission cooperation. The worm gear is rotatably installed at the upper end of the central rotating shaft. One end of the worm has a first transmission quick plug-in joint.

[0007] The electric grease gun includes a grease storage cylinder, a driving motor, a ratchet mechanism, and a grease outlet plunger pair. The grease storage cylinder has a grease replenishing port, and a second quick plug-in joint is connected to the grease replenishing port through a grease replenishing hose. The driving motor includes a motor output shaft, and a second transmission quick plug-in joint is arranged at the outer end of the motor output shaft. The first and second transmission quick plug-in joints can be quickly plugged and matched to achieve mutual transmission. The ratchet mechanism is installed in the middle of the motor output shaft. The ratchet mechanism includes an inner wheel, a ratchet pawl, and an outer wheel. The inner wheel is fixedly connected to the motor output shaft. The ratchet pawl is rotationally assembled on the inner wheel. The outer wheel has an eccentric inner circular hole, and ratchet teeth are arranged on the inner peripheral surface of the inner circular hole. The ratchet pawl is in one-way transmission cooperation with the ratchet teeth. When the motor output shaft rotates reversely, the inner wheel drives the outer wheel to rotate through the ratchet pawl. The inner wheel and the outer wheel form an eccentric wheel mechanism. The grease outlet plunger pair is driven by the eccentric wheel mechanism to pressurize and pump the lubricating grease in the grease storage cylinder out. When the motor output shaft rotates forward, the first quick plug-in joint and the second quick plug-in joint are plugged and matched, the ratchet pawl and the ratchet teeth are disengaged from meshing, and the second transmission quick plug-in joint of the motor output shaft can be inserted into the first transmission quick plug-in joint of the worm to drive the worm to rotate, and the grease suction auger rotates accordingly to convey the lubricating grease along the central grease suction pipe into the grease storage cylinder.

[0008] The beneficial effects of this solution are as follows: During normal operation, the electric grease gun controls the reverse rotation of the motor through a switch. The output shaft of the motor rotates in reverse, driving the inner wheel to rotate in reverse. The ratchet on the inner wheel meshes with the ratchet teeth on the outer wheel for transmission, driving the outer wheel to rotate in reverse. The outer wheel, as part of the eccentric wheel mechanism, can drive the grease outlet plunger pair to act, pumping out the grease in the grease storage cylinder and pumping it out under high pressure to lubricate the lubrication points. When the grease storage cylinder needs to be refilled, open the lid of the standard grease bucket, place the follower power suction cup from the bucket mouth into the bucket until it contacts the grease, then connect the second quick plug connector of the electric grease gun to the first quick plug connector of the follower power suction cup, and dock the second transmission quick plug connector of the electric grease gun with the first transmission quick plug connector of the follower power suction cup. Then, control the motor to rotate forward through the switch of the electric grease gun. At this time, due to the one-way meshing structure of the ratchet teeth and the ratchet, the two are disengaged at this time, that is, the inner wheel cannot transmit power to the outer wheel, and the inner wheel idles with the output shaft of the motor. However, the output shaft of the motor can drive the worm to rotate through the transmission of the second transmission quick plug connector and the first transmission quick plug connector, drive the turbine and the central rotating shaft to rotate, drive the spiral conveying blade to rotate, and use the conveying mechanism formed by the spiral conveying blade and the central grease suction pipe to convey the grease in the grease bucket upward. The grease sequentially passes through the grease inlet, grease outlet, first quick plug connector, second quick plug connector, refilling hose, etc. of the central grease suction pipe and enters the grease storage cylinder of the electric grease gun for rapid refilling. As the grease in the standard grease bucket is gradually sucked away, the liquid level will gradually drop. Under the vacuum suction force between the liquid level and the follower power suction cup, the follower power suction cup also drops with the drop of the liquid level to ensure that grease can be sucked at all times. From the above working process, it can be seen that this application can be directly adapted to the standard grease bucket. The follower power suction cup sinks into the grease bucket and forms a sealed structure with the bucket wall. Then, the electric grease gun rotates forward to drive the follower power suction cup to suck the grease from the grease bucket and supplement it into the grease storage cylinder of the electric grease gun, achieving the effect of rapid self-refilling. The refilling efficiency is significantly improved, the refilling process is more labor-saving and easier, and the follower power suction cup has a protective effect on the grease in the grease bucket, preventing dust, debris, rainwater, etc. from falling into the grease bucket to contaminate the grease.

[0009] Further, one end of the central rotating shaft extending below the disc body is provided with a grease scraping wheel. The grease scraping wheel rotates with the central rotating shaft to squeeze the grease towards the grease inlet of the central grease suction pipe. The setting of the grease scraping wheel ensures that the grease suction auger can easily suck the grease and prevents the grease suction auger from being emptied.

[0010] Further, the grease scraping wheel includes three grease scraping blades, and the grease scraping blades are arc-shaped structures bent towards the rotation direction. The grease scraping blades with this structure can form a centripetal driving force on the grease, causing the grease to move towards the grease inlet of the central grease suction pipe at the center.

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

[0012] Further, the lower end of the spiral conveying blade extends out from the lower end opening of the central grease suction pipe for guiding the lubricating grease to smoothly enter the central grease suction pipe.

[0013] Further, two support bearings are provided on the central rotating shaft. The support bearings include an inner ring, an outer ring and a roller assembly. The inner ring is sleeved and fixed on the central rotating shaft, and the outer ring is fixed on the inner wall of the central grease suction pipe through at least three uniformly distributed support rods respectively.

[0014] Further, the structure of the first drive quick-connect joint includes a cross-shaped boss and a positioning circular platform that is spaced around the cross-shaped boss. The structure of the second drive quick-connect head includes a matching cross-shaped groove.

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

[0016] Further, the drive motor is a speed-adjustable motor, and the forward rotation speed and reverse rotation speed of the drive motor can be respectively adjusted through a switch to control the grease replenishment speed and the grease discharge speed.

[0017] Further, a fixed bracket is fixed outside the central grease suction pipe, and both ends of the worm are rotatably assembled on the fixed bracket through bearings.

[0018] Further, the electric grease gun includes a detachable rechargeable battery.

[0019] Further, a spring and a piston are provided in the grease storage cylinder, and the grease replenishment port is arranged at one end far from the spring.

[0020] Further, it includes a portable packing box, and a placement position adapted to the outer shapes of the electric grease gun and the follow-up power suction cup is provided in the portable packing box.

[0021] Further, an annular groove is provided on the outer peripheral surface of the outer wheel, and one end of the plunger of the grease discharge plunger pair slides in the annular groove through a hooking structure. Description of the Drawings

[0035] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.

[0036] A specific embodiment of a submerged barrel self-compensating grease feeding electric grease feeding assembly adapted to a standard grease barrel of the present invention: As Figures 1-9 shown, the submerged barrel self-compensating grease feeding electric grease feeding assembly adapted to a standard grease barrel mainly includes a follow-up power suction cup 2, an electric grease gun 3 and a portable packing box. The portable packing box is provided with a placement position adapted to the outer shapes of the electric grease gun 3 and the follow-up power suction cup 2.

[0037] As Figure 1As shown in the figure, the follow-up power suction cup 2 is used to sink into a standard grease barrel and suck out the grease, including a disk body 21, a sealing rubber ring 22, a central grease suction pipe 23, a grease suction auger 24 and a worm and worm gear mechanism 25; the sealing rubber ring 22 is arranged on the outer periphery of the disk body 21, and the outer periphery of the sealing rubber ring 22 has an elastic deformation part for sealing and sliding cooperation with the barrel wall of the grease barrel. The top of the central grease suction pipe 23 has a cover 231. The central grease suction pipe 23 is arranged at the center of the disk body 21. The lower end opening of the central grease suction pipe 23 communicates with the part below the disk body 21 to form a grease inlet 232. One side of the upper part of the central grease suction pipe 23 has a grease outlet 233, and a first quick plug connector 234 is connected at the grease outlet 233. A grease suction auger 24 is rotationally assembled in the central grease suction pipe 23. The grease suction auger 24 includes a central rotating shaft 241 and spiral conveying blades 242 spirally arranged thereon. The outer diameter of the spiral conveying blades 242 is the same as the inner diameter of the central grease suction pipe 23. The upper end of the central rotating shaft 241 extends outward after passing through the cover 231, and the upper end of the central rotating shaft 241 is rotationally and sealingly matched with the cover 231. The worm and worm gear 252 mechanism includes a turbine 251 and a worm 252 in transmission cooperation. The turbine 251 is rotatably installed at the upper end of the central rotating shaft 241, and one end of the worm 252 has a first transmission quick plug connector 2521. The lower end of the spiral conveying blade 242 extends out of the lower end opening of the central grease suction pipe 23 for a certain distance to guide the grease to smoothly enter the central grease suction pipe 23. As Figure 1 , 3 As shown in the figure, a grease scraping wheel 26 is arranged at one end of the central rotating shaft 241 extending below the disk body 21. The grease scraping wheel 26 rotates with the central rotating shaft 241 to squeeze the grease towards the grease inlet 232 of the central grease suction pipe 23. The arrangement of the grease scraping wheel 26 ensures that the grease suction auger 24 can easily suck the grease and prevents the grease suction auger 24 from being emptied. The grease scraping wheel 26 includes three grease scraping blades 261, and the grease scraping blades 261 are arc-shaped structures bent towards the rotation direction. The grease scraping blades 261 with this structure can form a centripetal driving force on the grease, so that the grease moves towards the grease inlet 232 of the central grease suction pipe 23 at the center. The grease scraping blades 261 are made of a steel plate with a thickness of not less than 2 mm. As Figure 1 , 2 As shown in the figure, two support bearings 27 are arranged on the central rotating shaft 241. The support bearings 27 include an inner ring 271, an outer ring 272 and a roller assembly 273. The inner ring 271 is sleeved and fixed on the central rotating shaft 241, and the outer ring 272 is respectively fixed on the inner wall of the central grease suction pipe 23 through at least three uniformly distributed support rods 274. The outer diameter of the disk body 21 is not greater than the minimum barrel inner diameter of the standard grease barrel, and the outer diameter of the sealing rubber ring 22 is not less than the minimum barrel inner diameter of the standard grease barrel. A fixed bracket is fixed outside the central grease suction pipe 23, and both ends of the worm 252 are respectively rotationally assembled on the fixed bracket through bearings.

[0038] AsFigure 6 , 9 As shown in 9 , the electric grease gun 3 includes a grease storage cylinder 31, a drive motor 32, a ratchet mechanism 33, and a grease outlet plunger pair 34. The grease storage cylinder 31 has a grease replenishment port 311, and a second quick plug connector is connected to the grease replenishment port 311 through a grease replenishment hose. The drive motor 32 includes a motor output shaft 321, and a second drive quick plug connector 3211 is provided at the outer end of the motor output shaft 321. The first and second drive quick plug connectors 3211 can be quickly plugged and matched 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. The pawl 332 is rotatably assembled on the inner wheel 331. The outer wheel 333 has an eccentric inner circular hole, and ratchet teeth 3331 are provided on the inner peripheral surface of the inner circular hole. The pawl 332 is in one-way drive cooperation with the ratchet teeth 3331. When the motor output shaft 321 rotates reversely, 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 outlet plunger pair 34 is driven by the eccentric wheel mechanism to pressurize and pump out the grease in the grease storage cylinder 31. When the motor output shaft 321 rotates forward, the first quick plug connector 234 is plugged and matched with the second quick plug connector, the pawl 332 is disengaged from the ratchet teeth 3331, and the second drive quick plug connector 3211 of the motor output shaft 321 can be inserted into the first drive quick plug connector 2521 of the worm 252 to drive the worm 252 to rotate. The grease suction auger 24 rotates accordingly, and the grease is conveyed along the central grease suction pipe 23 into the grease storage cylinder 31. The drive motor 32 is a speed control motor, and the forward rotation speed and reverse rotation speed of the drive motor 32 can be respectively adjusted through a switch to control the grease replenishment speed and the grease outlet speed. The electric grease gun 3 includes a detachable rechargeable battery 35. A spring 312 and a piston 313 are provided in the grease storage cylinder 31, and the grease replenishment port 311 is provided at one end far from the spring 312. An annular groove 3332 is provided on the outer peripheral surface of the outer wheel 333, and one end of the plunger of the grease outlet plunger pair 34 slides in the annular groove 3332 through a hooking structure. As Figure 5 , 7 shown in 7 , the structure of the first drive quick plug connector 2521 includes a cross-shaped boss 25211 and a positioning circular platform 25212 that is spaced around the cross-shaped boss 25211. The structure of the second drive quick plug connector head includes a matching cross-shaped groove 32111.

[0039] During normal operation, the electric grease gun 3 controls the motor to reverse through a switch. The output shaft 321 of the motor reverses, driving the inner wheel 331 to reverse. The ratchet 332 on the inner wheel 331 meshes with the ratchet teeth 3331 on the outer wheel 333 for transmission, driving the outer wheel 333 to reverse. The outer wheel 333, as part of the eccentric wheel mechanism, can drive the grease outlet plunger pair 34 to act, pumping out the grease in the grease storage cylinder 31 and pumping it out under high pressure to lubricate the lubrication points. When the grease storage cylinder 31 needs to be refilled with grease, open the lid of the standard grease barrel, place the follow-up power suction cup 2 into the barrel from the barrel mouth until it contacts the grease, then connect the second quick insertion joint of the electric grease gun 3 to the first quick insertion joint 234 of the follow-up power suction cup 2, and dock the second transmission quick insertion joint 3211 of the electric grease gun 3 with the first transmission quick insertion joint 2521 of the follow-up power suction cup 2. Then, control the motor of the electric grease gun 3 to rotate forward through the switch. At this time, due to the one-way meshing structure of the ratchet teeth 3331 and the ratchet 332, the two disengage from meshing at this time, that is, the inner wheel 331 cannot transmit power to the outer wheel 333, and the inner wheel 331 idles with the output shaft 321 of the motor. However, the output shaft 321 of the motor can drive the worm 252 to rotate through the transmission between the second transmission quick insertion joint 3211 and the first transmission quick insertion joint 2521, driving the turbine 251 and the central rotating shaft 241 to rotate, and further driving the spiral conveying blade 242 and the grease scraping wheel 26 to rotate. The grease scraping blade 261 of the grease scraping wheel 26 can form a centripetal driving force on the grease, causing the grease to move towards the grease inlet 232 of the central grease suction pipe 23 at the center. Then, using the conveying mechanism formed by the spiral conveying blade 242 and the central grease suction pipe 23, the grease in the grease barrel is conveyed upward. The grease successively passes through the grease inlet 232, grease outlet 233 of the central grease suction pipe 23, the first quick insertion joint 234, the second quick insertion joint, the grease replenishment hose, etc. and enters the grease storage cylinder 31 of the electric grease gun 3 for rapid grease replenishment. As the grease in the standard grease barrel is gradually sucked away, the liquid level will gradually drop. Under the vacuum suction force between the liquid level and the follow-up power suction cup, the follow-up power suction cup also drops with the drop of the liquid level to ensure that grease can be sucked at all times. From the above working process, it can be seen that this application can be directly adapted to the standard grease barrel. The follow-up power suction cup 2 sinks into the grease barrel and forms a sealed structure with the barrel wall. Then, the electric grease gun 3 rotates forward to drive the follow-up power suction cup 2 to suck the grease from the grease barrel and replenish it into the grease storage cylinder 31 of the electric grease gun 3, achieving the effect of rapid self-grease replenishment. The grease replenishment efficiency is significantly improved, the grease replenishment process is more labor-saving and easier, and the follow-up power suction cup 2 has a protective effect on the grease in the grease barrel, preventing dust, debris, rainwater, etc. from falling into the grease barrel to contaminate the grease.
