[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1-7, the present utility model provides a technical solution: an improved fuel tank with an automatically replaceable filter. A suction pipe 1.1 is sleeved in the middle of one side wall of the fuel tank body 1. The filter 4 is threadedly sleeved at the inner end of the suction pipe 1.1. A metal mesh 5 is provided on one side of the middle part of the inner cavity of the fuel tank body 1 close to the suction pipe 1.1. When the suction pipe 1.1 sucks the oil liquid, it is filtered by the filter 4, so that the impurities in the oil liquid are retained in the filter 4; the metal mesh 5 blocks air bubbles from entering the suction pipe 1.1, which is convenient for the precise control of the system and improves the stability of the system.

[0029] A through hole 1.2 is opened in the front wall of the fuel tank body 1 at a position directly opposite to the filter 4; the pushing and disassembling assembly 3 includes a support column 3.1 provided on the front side of the fuel tank body 1, a third telescopic cylinder 3.2 longitudinally provided at the top of the support column 3.1 and directly opposite to the through hole 1.2, a cylindrical shell 3.3 fixed to the outer edge of the through hole 1.2 at the rear end, a cylindrical telescopic member 3.4 slidably sleeved in the cylindrical shell 3.3 and fixed to the rear end of the piston rod of the third telescopic cylinder 3.2, and clamping members 3.5 and clamping and rotating members 3.6 provided in pairs at the rear end of the cylindrical telescopic member. A perforation 3.3.1 is provided on the side wall of the cylindrical shell 3.3 close to the front end; the storage and delivery assembly 2 includes a plurality of storage cylinders 2.5 that can perform circular motion in a vertical plane and are used to store the filter 4, and a pushing mechanism that pushes the filter 4 in the storage cylinder 2.5 to between the clamping member 3.5 and the clamping and rotating member 3.6 through the perforation 3.3.1.

[0030] In summary, when the filter 4 needs to be replaced, the third telescopic cylinder 3.2 pushes the cylindrical telescopic member 3.4 to slide backward relative to the cylindrical shell 3.3, so that the clamping member 3.5 and the clamping and rotating member 3.6 correspond to the filter 4. The clamping member 3.5 and the clamping and rotating member 3.6 cooperate to screw and remove the filter 4 from the suction pipe 1.1. Subsequently, the fourth telescopic cylinder 3.3 pulls the cylindrical telescopic member 3.4 back, so that the filter 4 is aligned with the perforation 3.3.1.

[0031] The pushing mechanism in the storage and delivery assembly 2 pushes the filter 4 in the storage cylinder 2.5 towards the perforation 3.3.1, so that the removed filter 4 is pushed off by the new filter 4. At this time, the new filter 4 is clamped between the clamping member 3.5 and the clamping and rotating member 3.6. The third telescopic cylinder 3.2 pushes the cylindrical telescopic member 3.4 again, so that the new filter 4 is aligned with the nozzle of the suction pipe 1.1. Subsequently, the clamping member 3.5 and the clamping and rotating member 3.6 cooperate to screw and install the new filter 4 into the nozzle of the suction pipe 1.1 to complete the replacement operation of the filter 4.

[0032] The storage and delivery assembly 2 comprises a bracket 2.1 arranged at the front side of the middle of the oil tank body 1, a turntable 2.2 arranged at the top of the bracket 2.1, a connecting rod 2.3 fixed to the outer peripheral wall of the turntable 2.2 in the radial direction, a telescopic cylinder 1 2.4 arranged at the outer side of the end of the connecting rod 2.3 in the transverse direction, a storage cylinder 2.5 arranged at the inner side of the end of the connecting rod 2.3 in the transverse direction and fixed to the piston rod of the telescopic cylinder 1 2.4, and a telescopic cylinder 2.6 arranged in the inner cavity of the storage cylinder 2.5. A power device for driving the turntable 2.2 to rotate is arranged at the top of the bracket 2.1. That is, new filters 4 are placed in multiple storage cylinders 2.5 respectively, and the power device drives the turntable 2.2 to rotate, so that the filter 4 in the storage cylinder 2.5 rotating to the highest end is directly opposite to the perforation 3.3.1; the telescopic cylinder 1 2.4 first pushes the storage cylinder 2.5 to the position close to the perforation 3.3.1, and then the telescopic cylinder 2.6 pushes the filter 4 in the storage cylinder 2.5 into the perforation 3.3.1.

[0033] A rectangular groove 3.4.1 is provided between the two side walls of the inner end of the cylindrical telescopic member 3.4 along its axial direction, a clamping member 3.5 is fixed to the rear end of the inner cavity of the rectangular groove 3.4.1, and a clamping rotating member 3.6 is provided at the front of the inner cavity of the rectangular groove 3.4.1. Among them, the clamping member 3.5 includes an arc-shaped member 3.5.1 fixed to the rear end of the inner cavity of the rectangular groove 3.4.1, and a roller shaft 1 3.5.2 is rotatably installed in a plurality of grooves arranged along the axial direction of the arc-shaped member 3.5.1. The clamping rotating member 3.6 includes a telescopic cylinder 4 3.6.1 whose piston cylinder is fixed to the front wall of the inner cavity of the rectangular groove 3.4.1, a support block 2.6.2 fixed to the rear end of the piston rod of the telescopic cylinder 4 3.6.1, and an arc-shaped block 3.6.3 fixed to the top and bottom ends of the support block 2.6.2. A roller shaft 2 3.6.4 is rotatably installed in a groove arranged along the axial direction in the middle part of the arc-shaped block 3.6.3, and a power mechanism for driving the roller shaft 2 3.6.4 to rotate is provided on the support block 2.6.2. A motor 3.6.5 is mounted laterally in the middle of the support block 2.6.2, a driving gear 3.6.6 is fixedly mounted on the power output shaft of the motor 3.6.5, and a driven gear 3.6.7 matching the driving gear 3.6.6 is fixedly mounted on the end of the center shaft of the roller shaft 2 3.6.4.

[0034] That is, when the piston rod of telescopic cylinder four 3.6.1 is extended, it can embrace and clamp the new filter 4 pushed in through the perforation 3.3.1, and the motor 3.6.5 drives the roller shaft two 3.6.4 to rotate through the gear meshing transmission action, and the roller shaft two 3.6.4 drives the filter 4 to rotate by providing friction through the resistance-enhancing layer arranged on the outer peripheral wall.

[0035] Among them, the transverse extension length of the arc-shaped member 3.5.1 is less than that of the arc-shaped block 3.6.3. When the filter 4 is removed from the oil suction pipe 1.1, when the telescopic cylinder four 3.2 pushes the cylindrical telescopic member 3.4 backward, the arc-shaped member 3.5.1 of the clamping member 3.5 passes over the end face of the filter 4. When the telescopic cylinder four 3.6.1 pushes the support block 3.6.2, the end of the roller two 3.6.4 on the arc-shaped block 3.6.3 will abut against the filter 4. The motor 3.6.5 drives the rotation of the roller two 3.6.4 through the gear meshing drive. The roller two 3.6.4 facilitates driving the rotation of the filter 4 through the frictional action, so that the filter 4 gradually disengages from the oil suction pipe 1.1 and enters the cylindrical space surrounded by the roller one 2.5.2 and the roller two 3.6.4 until the filter 4 is completely disengaged from the oil suction pipe 1.1.

[0036] In order to reduce the sizes of the driving gear 3.6.6 and the driven gear 3.6.7, a transition gear 3.6.8 that meshes with both the driving gear 3.6.6 and the driven gear 3.6.7 is rotatably installed at a position on the side wall of the arc-shaped block 3.6.3 between the driving gear 3.6.6 and the driven gear 3.6.7.

[0037] A flow sensor is installed at the oil suction port of the oil suction pipe 1.1. The flow sensor controls the actions of each power device, telescopic cylinder, and motor through the PLC control system. That is, when the flow sensor monitors that the oil volume at the outlet of the oil suction port of the oil suction pipe 1.1 begins to decrease significantly, when the threshold value is reached, the operation process of automatically replacing the filter 4 is started in a timely manner.
