Description

Technical Field

[0001] The present invention relates to the technical field of centralized lubrication, and in particular to a grease stirring device for a centralized lubrication pump. Background Art

[0002] Centralized lubrication systems are commonly used to provide continuous grease lubrication for buses, trucks, construction machinery, and industrial production machinery. Grease is stored in a fuel tank and then enters the pump housing through a distribution plate. A gear pump or plunger pump, in conjunction with a distributor, delivers the grease to designated lubrication points in a timed and quantitative manner. Due to its viscosity, grease cannot be automatically transferred from the distribution plate to the pump. A device is required to continuously push the grease from the tank into the pump, thus necessitating the use of a stirring rod with an oil-pushing function. At present, the stirring rod has the following main problems: 1. The stirring rod does not stick to the wall of the oil tank to scrape the oil, but only plays the role of stirring the oil; 2. The stirring rod does not have the oil pressing function, but only plays the role of stirring the oil; 3. Even if the stirring rod is in contact with the wall of the oil tank and has a certain oil scraping action, because it is a straight rod, some of the oil moves upward when pushing the oil and stays on the wall of the oil tank, resulting in incomplete oil scraping; 4. If the stirring rod is too straight and too thin, it will directly pass through the oil and the oil will not fall, or the stirring rod is too thick, making the cross-section too large, resulting in excessive stirring resistance, consuming total power, and reducing the output power of the oil pump. Summary of the Invention

[0003] In order to solve the existing problems, the present invention provides a grease stirring device for a centralized lubrication pump. The stirring mechanism of this patent integrates oil scraping, stirring and oil pushing, and has the advantages of good adhesion to the oil tank wall, thorough oil scraping, low resistance and good stirring effect.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a grease stirring device for a centralized lubrication pump, the lubrication pump includes an oil tank and an oil pump body, the oil tank is arranged above the oil pump body, the stirring device is arranged in the oil tank, an oil distribution plate is provided at the bottom of the oil tank, the oil tank and the oil pump body are connected through the oil distribution plate, the stirring device is arranged above the oil distribution plate, the stirring device includes a driving motor and a stirring mechanism, the driving motor is arranged below the oil distribution plate, the stirring mechanism is connected to the motor shaft of the driving motor, and the stirring mechanism includes an oil pressure plate I, an oil pressure plate II and an oil scraper for scraping grease off the inner wall of the oil tank.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the scope of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "horizontal", "longitudinal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] A grease stirring device for a centralized lubrication pump, the lubrication pump includes an oil tank 2 and an oil pump body 5, the oil tank 2 is arranged above the oil pump body 5, the stirring device is arranged in the oil tank 2, an oil distribution plate 3 is arranged at the bottom of the oil tank 2, the oil tank 2 and the oil pump body 5 are connected through the oil distribution plate 3, the oil distribution plate 3 is provided with a plurality of oil distribution holes, the oil tank 2 and the oil pump body 5 are connected through the oil distribution holes, the stirring device is arranged above the oil distribution plate 3, the stirring device includes a drive motor 4 and a stirring mechanism 1, the drive motor 4 is arranged below the oil distribution plate 3, the stirring mechanism 1 and the motor of the drive motor 4 The invention provides a stirring mechanism for scraping, stirring and pushing oil for the grease tank. The oil pressure plate I12 plays the role of stirring, the oil pressure plate II122 plays the role of pushing oil, and the oil scraper 11 plays the role of scraping oil from the inner wall of the tank. The motor shaft of the drive motor 4 is set at the center of the oil distribution plate 3. When the drive motor is driven, the oil pressure plate I12 rotates in the tank with the center of the oil distribution plate 3 as the center. The length of the oil pressure plate I12 is less than the radius of the tank, and the length of the oil scraper 11 is also less than the height of the tank. Ensure that the stirring mechanism 1 is located inside the tank.

[0022] The stirring mechanism 1 includes an oil pressure plate I12, an oil pressure plate II122 and an oil scraper 11 for scraping grease off the inner wall of the oil tank 2; the oil pressure plate I12, the oil pressure plate II122 and the oil scraper 11 are made of non-metallic materials, and a mounting hole 121 is opened on the oil pressure plate I12. The oil pressure plate I12 is mounted on the motor shaft of the drive motor 4 through the mounting hole 121, and the oil pressure plate rotates synchronously with the motor shaft.

[0023] The oil pressure plate II 122 is tilted and arranged on one side of the oil pressure plate I 12 along the length direction of the oil pressure plate I 12. The angle between the oil pressure plate II 122 and the oil pressure plate I 12 is 90-170 degrees.

[0024] By setting the oil pressing plate II 122, the oil scraping is more thorough, and no grease is pushed above the oil pressing plate I 12, thus saving grease; the angle between the oil pressing plate II 122 and the oil pressing plate I 12 can be adjusted according to the viscosity of the grease;

[0025] The oil scraper 11 is vertically positioned above the oil pressure plate II 122 and welded to the oil pressure plate II 122. It is a vertically curved plate, with a greater width at its base than at its top. The oil scraper 11 forms a natural transition from bottom to top, and its top is formed by an eagle beak structure 14, which has an acute angle. Oil baffles 141 are located on either side of the eagle beak structure 14. Together, these two oil baffles 141 and the eagle beak structure 14 form an oil guide groove 13 for draining grease. The length of the oil baffles 141 can be adjusted based on the motor power. The side of the oil scraper rod facing the direction of the drive motor is chamfered to reduce motion resistance.

[0026] Specific operation process: The stirring device is installed in the oil tank 2, and the oil pressure plate I12 is fixed to the motor shaft of the driving motor through a locking nut. The oil pressure plate I12 can be driven to rotate by the driving motor. The oil pressure plate II122 presses the grease into the oil distribution plate 3 when rotating. The oil tank 2 is connected to the oil pump body 5 by bolts.

[0027] The oil pressure plate I12 rotates clockwise, and the oil pressure plate II122 presses the grease into the oil distribution plate 3. At the same time, the oil scraper plate 11 scrapes the oil on the inner wall of the oil tank 2 while moving, and the hanging oil falls on the oil distribution plate 3.

[0028] Because the top of the oil scraper 11 has an oil guide groove 13, grease will not accumulate on the top of the oil scraper 11, but will fall directly onto the oil pressure plate 3. Under the action of the eagle beak structure 14 of the oil scraper 11, the scraped grease will no longer be pressed upward, but will instead enter the guide groove 13 downward. At the same time, due to the provision of the oil guide groove 13 structure, the grease on the oil scraper 11 will not accumulate. During the oil scraping process, the grease will form a spiral strip, which will fall onto the oil distribution plate 3 behind the oil pressure plate II 122, making it easier for the oil pressure plate to press the oil into the oil distribution plate 3 during the next rotation, and then push the grease into the oil pump body 5.

[0029] In addition to the above embodiments, the device of the present invention may also have other forms. It should be pointed out that any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the present invention.
