In conjunction with the driving mechanism, the filter bucket net can be shaken and rotated in the vertical direction, thereby increasing the filtering and cleaning effect, and thus increasing the filtering effect.

[0011] Axial flow fan blades are fixedly installed inside the filter bucket net;

[0012] The middle part of the axial flow fan blade is rotatably connected with a connecting block via a one-way rotating shaft;

[0013] The connecting block is connected with a driving mechanism which is driven to rotate the filter net by the impact of the lubricating oil.

[0014] Preferably, the driving mechanism comprises a support block, a spring, a spiral sheet and a cannula, the cannula is fixedly mounted on the inner bottom of the filter cartridge, the top end of the cannula is closed, and a rectangular opening for the spiral sheet to pass through is provided at the closed end, the spiral sheet is fixedly connected to the connecting block, the support block is located below the connecting block, and a through opening for the spiral sheet to pass through is provided in the middle of the support block, the spring is movably sleeved on the outer periphery of the spiral sheet, one end of the spring is fixedly connected to the connecting block, and the other end of the spring is fixedly connected to the cannula.

[0018] The above technical solution of the utility model has the following beneficial technical effects:

[0019] Lubricating oil is added from the liquid inlet hopper, and the lubricating oil scatters and hits the baffle. The baffle is impacted by the lubricating oil, which acts on the spring. The spring is compressed, so that the filter net can shake in the vertical direction, and the filter net moves downward, so that the spiral strips continuously pass through the rectangular opening of the insertion tube and extend into the interior of the insertion tube. Due to the spiral setting of the spiral strips, the position of the insertion tube remains unchanged, and the spiral strips rotate to drive the filter net to rotate and perform rotary filtration. The lubricating oil is filtered through the filter net and acts on the axial flow fan blades to drive the filter net, which plays a role of rotary filtration. Due to the setting of the shape of the filter net, the waste chips located at the mesh can be thrown out under the action of centrifugal force to increase the filtering effect.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] like Figure 1-3 As shown, a rolling lubricating oil filtering structure proposed by the utility model comprises a filter cartridge 1, the filter cartridge 1 is upwardly opened, and a blocking cover 2 is detachably connected to the opening;

[0026] The plugging cover 2 can be detachably connected to the filter cartridge 1 by means of bolts or a snap lock;

[0027] The sealing cover 2 is provided with a liquid inlet;

[0028] A filter net 3 is slidably sleeved inside the filter cylinder 1, and a baffle 4 is fixedly installed at the top of the filter net 3 corresponding to the opening;

[0029] Axial flow blades 5 are fixedly installed inside the filter bucket net 3;

[0030] The middle part of the axial flow blade 5 is rotatably connected to a connecting block 7 via a one-way rotating shaft 6;

[0031] The connecting block 7 is connected with a driving mechanism 8 which is driven by the lubricating oil to impact the filter bucket net 3 and drive the filter bucket net 3 to rotate.

[0032] In an optional embodiment, the driving mechanism 8 includes a support block 81, a spring 82, a spiral strip 83 and a cannula 84. The cannula 84 is fixedly installed at the bottom of the filter cartridge 1. The top of the cannula 84 is closed, and a rectangular opening is provided at the closed end for the spiral strip 83 to spirally pass through. The spiral strip 83 is fixedly connected to the connecting block 7. The support block 81 is located below the connecting block 7, and a through opening is provided in the middle of the support block 81 for the spiral strip 83 to pass through. The spring 82 is movably sleeved on the outer periphery of the spiral strip 83. One end of the spring 82 is fixedly connected to the connecting block 7, and the other end of the spring 82 is fixedly connected to the cannula 84.

[0033] It should be noted that the rotation of the spiral blade rod 83 drives the axial flow blade 5 to turn in the same direction as the direction in which the lubricating fluid acts on the axial flow blade 5 to rotate.

[0034] In an optional embodiment, a drainage port is provided at the bottom of the outer circumference of the insertion tube 84 .

[0035] It should be noted that the lubricating oil entering the interior of the insert tube 84 from the top end can be discharged, and the lubricating oil entering the interior of the insert tube 84 increases the smoothness of the spiral strip 83 entering the interior of the insert tube 84.

[0036] In an optional embodiment, a ball 85 is rotatably sleeved on the top of the support block 81 and is rollingly connected to the bottom of the connection block 7 .

[0039] It should be noted that the discharge end of the liquid inlet hopper 9 faces the baffle 4 .

[0040] In the utility model, lubricating oil is added to the liquid inlet hopper 9, and the lubricating oil scatters and hits the baffle 4. The baffle 4 is impacted by the lubricating oil, which acts on the spring 82. The spring 82 is compressed, so that the filter bucket net 3 can shake in the vertical direction, and the filter bucket net 3 moves downward, so that the spiral strips 83 continuously pass through the rectangular opening of the insertion tube 84 and extend into the interior of the insertion tube 84. Due to the spiral setting of the spiral strips 83, the position of the insertion tube 84 remains unchanged, and the spiral strips 83 rotate to drive the filter bucket net 3 to rotate and perform rotary filtration. The lubricating oil is filtered through the filter bucket net 3 and acts on the axial flow fan blades 5, which can also drive the filter bucket net 3, and plays a role of rotary filtration. Due to the setting of the shape of the filter bucket net 3, the waste chips located at the mesh can be thrown out under the action of centrifugal force to increase the filtering effect.
