DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0033] See also Figure 1-7 The present invention provides a technical solution: a high-speed common rail vane pump, comprising an oil pump 1, an end cover 2 is provided on the top of the oil pump 1, the top of the oil pump 1 is in contact with the bottom of the end cover 2, a vane pump assembly 3 is rotatably connected inside the oil pump 1, and a cleaning mechanism 4 is provided on one side of the outside of the oil pump 1;
[0034] The cleaning mechanism 4 comprises:
[0035] A sealing shell 401 is fixedly connected to one side of the outside of the oil pump 1. A baffle 402 is fixedly connected to the bottom of the inner cavity of the sealing shell 401. A filter screen 403 is embedded inside the baffle 402. A rotating rod 404 is rotatably connected between the two side walls of the inner cavity of the filter screen 403. Three rotating plates 405 are fixedly connected to the outside of the rotating rod 404, so that the rotating plate 405 can drive the rotating rod 404 to rotate when it is rotated under force;
[0036] A blocking net 406 is embedded in one of the rotating plates 405, and a plate body 407 is fixedly connected to one side of the rotating rod 404. Cover bodies 408 are fixedly connected to both sides of the top of the plate body 407, and springs 409 are fixedly connected to the inside of the two cover bodies 408. Slide blocks 410 are fixedly connected to one end of the two springs 409, and connecting rods 411 are fixedly connected to one side of the two sliders 410. A roller assembly 412 is rotatably connected between the two connecting rods 411, and a cleaning fiber 413 is fixedly connected to the outside of the roller assembly 412, so that the roller assembly 412 can drive the spring 409 to deform when subjected to force.
[0037] When the oil pump 1 needs to be used for oil delivery, the worker first needs to connect the sealing housing 401 to the oil delivery device, and then connect the output end outside the oil pump 1 to the input device. When the oil starts to be input into the sealing housing 401, the oil will enter the inside of the baffle 402, and then pass through the inside of the filter 403, so that the impurities and debris in the oil are filtered out, so as to avoid the impurities and debris stuck inside the vane pump assembly 3 and cause malfunctions;
[0038] In the above working process, the oil will adhere impurities and debris to the outer surface of the filter 403 through the force of circulation. Since the oil in the baffle 402 is constantly circulating, the rotating plate 405 will be driven by the force of circulation to rotate clockwise. When the rotating plate 405 rotates, it will synchronously drive the rotating rod 404 to rotate. At this time, the plate body 407 rotates synchronously. When the cleaning fiber 413 contacts the roller assembly 412 and the filter 403, the roller assembly 412 and the cleaning fiber 413 will clean the surface of the filter 403. At the same time, the roller assembly 412 and the cleaning fiber 413 will move relative to the filter screen 403. During this process, the roller assembly 412 will rotate, so as to wipe the outer surface of the filter screen 403. Since the roller assembly 412 will be squeezed by the contact with the filter screen 403 during the rotation, the connecting rod 411 will synchronously drive the slider 410 to compress the spring 409, so as to achieve the omni-directional cleaning of the filter screen 403 and avoid the occurrence of blocking.
[0039] In the above working process, the roller assembly 412 will make relative motion with the scraper rod 414 during the rotation process, so that the cleaning fiber 413 can be cleaned after cleaning the filter screen 403, preventing the situation in which too much dirt adheres to the surface and causes poor cleaning effect;
[0040] During the above working process, since the dirt is doubly cleaned, temporary chaos will appear inside the oil. In order to prevent the dirt from spreading inside the sealed shell 401, the rotating plate 405 will synchronously drive the rotating rod 404 to rotate during the rotation process. The rotating rod 404 will synchronously drive the blocking net 406 to rotate at this time. Then, the rotation of the blocking net 406 can be used to collect the dirt that has spread inside the sealed shell 401, and completely leave the upper oil level of the oil and protrude from the oil surface, thereby avoiding clogging inside the filter net 403 and the spread of dirt.
[0041] See also Figure 6-9 The present invention provides a technical solution: a high-speed common rail vane pump, a scraper rod 414 is fixedly connected between the plates 407, a movable door 6 is rotatably connected to the top of the sealed housing 401, guide rods 415 are fixedly connected to both sides of the top of the plate 407, and the cross sections of the two guide rods 415 are both set to be arc-shaped, and a collecting mechanism 5 is provided inside the sealed housing 401. The collecting mechanism 5 includes a mounting plate 501, which is fixedly installed on a side wall of the inner cavity of the sealed housing 401, and a pipe body 502 is fixedly connected inside the mounting plate 501;
[0042] A sliding rod 503 is slidably connected to the inside of the tube body 502, and the shapes of the tube body 502 and the sliding rod 503 are both L-shaped. A collecting shell 504 is provided on the outside of the sliding rod 503, and the inner wall of the collecting shell 504 is in contact with the outer surface of the sliding rod 503. An end plate 505 is fixedly connected to one side of the collecting shell 504, and the end plate 505 is in an upward state. A collecting net 506 is embedded in the bottom of the collecting shell 504, and circular grooves are provided on both side walls of the inner cavity of the collecting shell 504, and a scraper 507 is slidably connected between the two circular grooves.
[0043] When the rotating plate 405 drives the blocking net 406 to rotate and contacts the end plate 505, the dirt adhering to the surface of the blocking net 406 will be scraped off to the inside of the collecting shell 504 and then stay inside the collecting net 506, thereby completing the collection of the dirt. In addition, because the rotating plate 405 drives the collecting shell 504 to rotate upward through its own curved surface, the collecting shell 504 will simultaneously drive the sliding rod 503 to slide into the inside of the tube body 502 during the upward movement. When the rotating plate 405 completely slides over the bottom of the collecting shell 504, the collecting shell 504 falls and resets. Then the end plate 505 contacts the guide rod 415 and drives the collecting shell 504 and the sliding rod 503 to slide into the inside of the tube body 502 again, thereby preventing the plate body 407 from being stuck due to its straight surface shape, thereby ensuring the use effect of the equipment.
[0044] When the above work is completed, the dirt will be caught by the collecting net 506, and then the staff will open the movable door 6, and then separate the collecting shell 504 from the sliding rod 503 and take the collecting shell 504 to the outside of the sealed shell 401, and then the staff will rotate the collecting shell 504 with the end plate 505 facing downward. At this time, the scraper 507 will start to rotate and slide due to its own weight, so as to achieve the effect of scraping and cleaning the dirt on the surface of the collecting net 506.
[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
