[0005] The present application provides a feeding device for aviation hydraulic oil, which adopts the following technical solution:

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 3 The present application provides an embodiment: a feeding device for aviation hydraulic oil, comprising a tank body 1, a motor 2 is fixedly arranged on the top of the tank body 1, a rotating shaft of the motor 2 is inserted into the tank body 1 and a foldable stirring member 3 is fixedly arranged, and the foldable stirring member 3 is driven by the motor 2 to rotate to stir the hydraulic oil in the tank body 1, thereby accelerating the mixing speed of the additive and the hydraulic oil.

[0029] The outer wall of the foldable stirring member 3 is provided with an external thread 4, and the outer wall of the foldable stirring member 3 is threaded with a first piston plate 5. As the foldable stirring member 3 rotates, the first piston plate 5 moves downward, and as the first piston plate 5 moves downward, the hydraulic oil is discharged easily.

[0030] The foldable stirring member 3 includes a rod body 31, and the outer wall of the lower end of the rod body 31 is provided with a plurality of receiving grooves 32 along the circumference. Stirring rods 33 are hinged in the plurality of receiving grooves 32 through pins. Torsion springs 34 are fixedly arranged at both ends of the pins. The end of the torsion spring 34 away from the pin is fixedly connected to the inner wall of the receiving groove 32. The receiving groove 32 is convenient for storing the stirring rod 33, and the pin and the stirring rod 33 are driven to deflect upward by the torsion spring 34. When the rod body 31 rotates, it is convenient to drive the stirring rod 33 to rotate and stir the hydraulic oil and the additive. When the first piston plate 5 moves downward, it contacts the stirring rod 33, thereby causing the stirring rod 33 to deflect downward and be stored in the receiving groove 32, and at the same time causing the torsion spring 34 to twist and deform.

[0031] The first piston plate 5 is movably arranged in the tank body 1, and two first limiting grooves 16 are vertically opened on the inner wall of the tank body 1. Two first limiting blocks 51 are symmetrically arranged on the outer wall of the first piston plate 5. The two first limiting blocks 51 are respectively located in the two first limiting grooves 16. The first limiting grooves 16 cooperate with the first limiting blocks 51 to limit the first piston plate 5. When the foldable stirring member 3 rotates, the first piston plate 5 drives the first limiting blocks 51 to slide up and down along the inner wall of the first limiting groove 16, and at the same time, it is convenient to increase the stability of the first piston plate 5 when moving.

[0032] A resistance plate 52 corresponding to the receiving groove 32 is fixedly provided on the top of the first piston plate 5. When the first piston plate 5 moves downward, the resistance plate 52 resists against the stirring rod 33 and causes the stirring rod 33 to be received in the receiving groove 32. When the first piston plate 5 moves downward, it resists against the stirring rod 33, thereby causing the stirring rod 33 to deflect downward and be received in the receiving groove 32. At the same time, the resistance plate 52 resists against the stirring rod 33, reducing the possibility of the stirring rod 33 being reset and unfolded.

[0033] A feeding tank 6 is fixedly connected to the top of the tank body 1, and the feeding tank 6 is connected to the tank body 1 through a delivery pipe 7. The feeding tank 6 delivers additives to the inside of the tank body 1 through the delivery pipe 7, and the additives and hydraulic oil are quickly mixed by rotating the foldable stirring element 3.

[0034] An outer spiral groove rod 8 is vertically arranged inside the tank body 1, and a through hole 9 for the outer spiral groove rod 8 to pass through is opened on the top of the first piston plate 5. A semicircular block 10 is fixedly arranged on the inner wall of the through hole 9. The semicircular block 10 slides along the inner wall of the spiral groove on the outer spiral groove rod 8. When the first piston plate 5 moves, the semicircular block 10 is driven to move and slide along the inner wall of the spiral groove on the outer spiral groove rod 8, thereby prompting the outer spiral groove rod 8 to rotate.

[0035] The upper end of the outer spiral groove rod 8 is inserted into the feeding tank 6 and fixed with a screw 11. The outer wall of the screw 11 is movably sleeved with a second piston plate 12. The outer spiral groove rod 8 can easily drive the screw 11 to rotate, and as the screw 11 rotates, the second piston plate 12 can be controlled to move up and down.

[0036] Two second limiting grooves 62 are vertically formed on the inner wall of the feeding tank 6, and two second limiting blocks 121 are symmetrically arranged on the outer wall of the second piston plate 12. The two second limiting blocks 121 are respectively located in the two second limiting grooves 62. The first piston plate 5 is limited by the cooperation between the second limiting grooves 62 and the second limiting blocks 121. When the outer spiral groove rod 8 drives the screw 11 to rotate, the second piston plate 12 drives the second limiting blocks 121 to slide up and down along the inner wall of the second limiting groove 62, thereby increasing the stability of the second piston plate 12 when moving.

[0037] See the attached drawings in the specification Figure 1 and Figure 2 A feed pipe 13 is fixedly connected to the outer wall in the middle of the tank body 1, and a discharge pipe 14 is fixedly connected to the outer wall at the lower end of the tank body 1. One end of the delivery pipe 7 is fixedly connected to the outer wall at the upper end of the feeding tank 6, and the other end of the delivery pipe 7 is fixedly connected to the outer wall in the middle of the tank body 1. The hydraulic oil is conveniently delivered to the inside of the tank body 1 through the feed pipe 13, and the hydraulic oil is conveniently discharged through the discharge pipe 14. The additive is conveniently delivered to the tank body 1 and mixed with the hydraulic oil through the delivery pipe 7. The feed pipe 13 is connected to the hydraulic oil storage device, and the hydraulic oil is supplied to the tank body 1 through the feed pipe 13. The mixed hydraulic oil in the tank body 1 is conveniently discharged through the discharge pipe 14, and the discharge pipe 14 is connected to the liquid inlet end of the refueling equipment, thereby realizing the addition of hydraulic oil.

[0038] A hopper 61 is vertically fixed on the top of the feeding tank 6, and a control valve 15 is provided on the hopper 61, the feed pipe 13 and the discharge pipe 14. The hopper 61 is convenient for the operator to pour additives into the feeding tank 6, and the control valve 15 is convenient for controlling the opening and closing of the hopper 61, the feed pipe 13 and the discharge pipe 14.

[0039] Working principle: When the feeding device for aviation hydraulic oil is used, the motor 2 drives the foldable stirring member 3 to rotate to stir the hydraulic oil in the tank 1, and the foldable stirring member 3 rotates to cause the first piston plate 5 to move downward, so that the hydraulic oil can be discharged easily as the first piston plate 5 moves downward;

[0040] As the first piston plate 5 moves downward, the semicircular block 10 moves and slides along the inner wall of the spiral groove on the outer spiral groove rod 8, thereby prompting the outer spiral groove rod 8 to drive the screw 11 to rotate, and then prompting the second piston plate 12 to move upward and transport the additive in the feeding tank 6 to the inside of the tank body 1, and as the foldable stirring element 3 rotates, the additive and the hydraulic oil are quickly mixed.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
