Technical Field

[0001] The utility model relates to the technical field of hydraulic oil tanks, in particular to a hydraulic oil storage tank. Background Art

[0002] Although the current hydraulic oil storage box is equipped with a filter, it lacks a clean collection structure for impurities on the filter. The conventionally installed clean collection structure usually requires an additional power source. Installing a power source device on the hydraulic oil tank will create certain safety hazards. Therefore, this solution provides a hydraulic oil storage box that uses the fluidity of the hydraulic oil as a power source to achieve clean collection of the filter. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present scheme provides a hydraulic oil storage box, which is achieved by the following specific technical means: it includes a hydraulic oil tank and a filter cylinder installed on the oil filling port of the hydraulic oil tank, the top of the filter cylinder is provided with an annular collecting chamber, and a funnel is inserted in the oil filling port, the capillary arranged at the bottom of the funnel is inserted into the filter cylinder, an elastic sealing assembly is arranged in the capillary, and a magnetic induction cleaning plate is provided on the outer sliding sleeve of the capillary, the outer edge of the magnetic induction cleaning plate slides against the inner wall of the filter cylinder, and the magnetic induction cleaning plate is magnetically connected to the elastic sealing assembly to achieve synchronous movement of the two.

[0004] Preferred technical solution one: the elastic sealing assembly includes a base slidably arranged in the capillary and a sealing ball arranged on the top of the base, a supporting spring is connected between the bottom wall of the base and the bottom wall of the filter cylinder, the sealing ball is used to seal the bottom opening of the funnel, and the diameter of the bottom opening of the funnel is smaller than the inner diameter of the capillary.

[0005] Preferred technical solution 2: A notch is provided on the side wall of the bottom end of the capillary tube.

[0006] Preferred technical solution three: the filter cylinder is composed of a mesh cylinder body and an annular seat detachably arranged at the top of the mesh cylinder body.

[0007] Preferred technical solution four: the top surface of the magnetic induction cleaning plate is an upward convex arc structure.

[0008] Preferred technical solution five: the bottom wall of the funnel piece is opposite to the bottom wall of the mesh cylinder, and a scraper is slidably provided on the bottom wall of the funnel piece. When the bottom end of the scraper moves closer to the magnetic induction cleaning plate, it contacts the top surface of the magnetic induction cleaning plate, and a reset spring is connected between the scraper and the funnel piece wall.

[0009] The above structure enables this solution to have the following beneficial effects:

[0010] 1. Use the fluidity of hydraulic oil during injection to push the plugging ball away from the funnel, and then use the magnetic induction principle to move the magnetic induction cleaning plate down to the bottom wall of the net cylinder. After the oil filling and filtration are completed, the plugging ball moves up to remove the impurities after each filtration. The whole process does not require any additional power equipment.

[0011] 2. The arc structure of the magnetic induction cleaning plate can be used in conjunction with the hanging plate to further improve the collection of impurities after cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 and Figure 7 The hydraulic oil storage box comprises a hydraulic oil tank 1 and a filter cylinder 2 installed on the oil filling port of the hydraulic oil tank 1. The top side wall of the filter cylinder 2 is provided with an annular collecting chamber 23, and a funnel piece 3 is inserted in the oil filling port. The funnel piece 3 is inserted into the filter cylinder 2 through a capillary tube 4 arranged at the bottom opening. The bottom end of the capillary tube 4 contacts the bottom wall of the mesh cylinder body 21. A notch 41 is provided on the bottom side wall of the capillary tube 4. An elastic plugging component 5 is arranged in the capillary tube 4. The elastic plugging component 5 comprises a base 51 slidably arranged in the capillary tube 4 and a sealing ball 53 arranged on the top of the base 51. A supporting spring 54 is connected between the bottom wall of the base 51 and the bottom wall of the filter cylinder 2. The sealing ball 53 is used to seal the bottom opening of the funnel piece 3. At the same time, the bottom opening diameter of the funnel piece 3 is smaller than the inner diameter of the capillary tube 4. At the same time, a magnetic induction cleaning plate 6 is provided on the outer sliding sleeve of the capillary tube 4, and the outer edge of the magnetic induction cleaning plate 6 fits the filter cylinder 2, the magnetic induction cleaning plate 6 is magnetically connected to the base 51 to achieve synchronous movement of the two. When hydraulic oil is injected into the filter cylinder 2 through the funnel piece 3, the hydraulic oil pushes the blocking ball 53 to move downward to release the blocking of the capillary 4. The blocking ball 53 drives the base 51 to compress the support spring 54 and move downward until the blocking ball 53 moves down to the height of the notch 41. At this time, the hydraulic oil flows out of the notch 41 and enters the filter cylinder 2 for filtration. At the same time, the magnetic induction cleaning plate 6 moves down to the bottom wall of the filter cylinder 2. After the oil injection is completed, the support spring 54 rebounds and moves again to the top of the capillary 4 to block the bottom of the funnel piece 3. At this time, the magnetic induction cleaning plate 6 moves upward to complete the cleaning of the inner wall of the filter cylinder 2, and pushes the cleaned impurities to the height of the annular collection chamber 23, and introduces the impurities into the annular collection chamber 23.

A reset spring 8 is connected between the scraper 7 and the wall of the funnel piece 3. In the initial state, the scraper 7 is in a state close to the capillary 4 under the action of the reset spring 8. The bottom end of the scraper 7 contacts the top surface of the magnetic induction cleaning plate 6 when the magnetic induction cleaning plate 6 moves up and approaches, and the bottom end of the scraper 7 slides against the magnetic induction cleaning plate 6 during the continuous upward movement of the magnetic induction cleaning plate 6, pushing the impurities on the magnetic induction cleaning plate 6 to the edge, thereby improving the collection effect.
