Description

Technical Field

[0001] This utility model specifically relates to the field of refrigerator oil draining technology, and more specifically to a variable position multi-angle drilling device for improving the thoroughness of oil draining from waste refrigerators. Background Technology

[0002] In the recycling and processing of used refrigerators, residual lubricating oil in the refrigeration system is a key challenge restricting resource utilization. Traditional oil draining processes generally use fixed drilling equipment to drill a single vertical hole at a predetermined position on the bottom of the refrigerator, relying on gravity to drain the oil naturally.

[0003] Due to the complex internal structure of refrigerators, the evaporator coils are distributed in a circuitous manner and have multiple layers of anti-leakage grooves. Fixed-position drilling can easily lead to the following problems: the fixed drilling position prevents the oil from being fully drained. Especially for refrigerators with complex irregular-shaped water tanks, a large amount of waste oil often remains in the bottom recess. Existing drilling equipment lacks angle adjustment function, making it difficult to optimize the drilling angle for different cabinet structures. This results in low oil filtration efficiency of the refrigerator, which cannot meet actual needs. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the present invention, a variable-position multi-angle drilling device for improving the thoroughness of oil draining from waste refrigerators includes an operating platform 20, a rotating ring 33, a drilling mechanism 40, and a support mechanism 50 mounted on a housing 10. At least one frame 30 is mounted on the operating platform 20. The rotating ring 33 is connected to one end of the frame 30. A gear ring 331 is fixedly mounted on the outer side of the rotating ring 33. A drive gear 32 is rotatably mounted on the frame 30, meshing with the gear ring 331. When the drive gear 32 rotates, it controls the rotation of the rotating ring 33 through the gear ring 331. At least one drilling mechanism 40 is mounted on the rotating ring 33. The support mechanism 50 is used to fix the refrigerator to be drained. The drilling mechanism 40 is used to make holes in the refrigerator, allowing liquid in the refrigerator to drain through the holes. In this embodiment, the liquid includes water and oil in the refrigerator.

[0021] The drilling mechanism 40 includes a mounting frame 41, a sleeve 42, and a motor base 46. The mounting frame 41 is fixedly connected to the rotating ring 33. One side of the sleeve 42 is hinged to the mounting frame 41. A hydraulic rod 48 is also fixedly mounted on the mounting frame 41. The telescopic end of the hydraulic rod 48 is hinged to the other side of the sleeve 42. When the length of the telescopic end of the hydraulic rod 48 changes, the angle between the sleeve 42 and the mounting frame 41 changes. The motor base 46 is slidably mounted inside the sleeve 42. A threaded sleeve 45 is fixedly mounted on one side of the motor base 46, and a screw sleeve 45 is rotatably mounted on one side of the sleeve 42. A push screw 44 is threadedly connected to the sleeve 42. A drilling motor is installed inside the motor base 46, and a drill rod 47 is fixedly installed at the output end of the drilling motor. By controlling the rotation of the push screw 44, the sliding position of the motor base 46 inside the sleeve 42 is adjusted, thereby adjusting the drilling depth of the drill rod 47. Before drilling, the drilling angle can be adjusted by controlling the deflection of the sleeve 42 through the hydraulic rod 48, thus adjusting the drilling position of the drill rod 47. In addition, when the rotating ring 33 rotates, the drilling mechanism 40 rotates with the rotating ring 33, further changing the drilling position of the drill rod 47.

[0022] In this embodiment of the application, a rotary motor 43 is fixedly installed on the outer side of the sleeve 42, and the output end of the rotary motor 43 is fixedly connected to the push screw 44. The rotary motor 43 is used to drive the push screw 44 to rotate.

[0023] like Figures 1-4 As shown in this embodiment, the support mechanism 50 is concentrically arranged with the rotating ring 33. The support mechanism 50 includes a base 51 and a support platform 52. The base 51 is fixedly connected to the operating table 20. The base 51 has a ring structure and is provided with multiple arc-shaped grooves 551. The support platform 52 is rotatably connected to the operating table 20 through a universal joint coupling. At least one elastic connection mechanism 54 is provided between the support platform 52 and the base 51. When the support platform 52 is in a rotating state, the support platform 52 drives the elastic connection mechanism 54 to slide along the surface of the base 51. When the elastic connection mechanism 54 moves to the area of ​​the arc-shaped groove 551, the support platform 52 and the refrigerator on the support platform 52 tilt. When the support platform 52 continues to rotate, the refrigerator continues to shake, thereby promoting the drainage of liquid inside the refrigerator and preventing highly viscous oil from adhering to the inside of the refrigerator and being unable to drain.

[0024] Furthermore, in this embodiment, the elastic connection mechanism 54 includes an elastic connecting rod 541 and a sliding seat 542. One end of the elastic connecting rod 541 is fixedly connected to the support platform 52, and the other end of the elastic connecting rod 541 is movably connected to the sliding seat 542. The sliding seat 542 is slidably connected to the base 51, and the elastic connecting rod 541 can freely adjust its extension and retraction during the sliding of the sliding seat 542 along the base 51. To prevent the sliding seat 542 from detaching from the base 51, a magnetic connection can be used in actual use. For example, the sliding seat 542 can be made of magnets while the base 51 can be made of iron.

[0025] Furthermore, a rotary motor 55 is fixedly installed at the bottom of the operating table 20. The output end of the rotary motor 55 is connected to the universal joint coupling, and the rotary motor 55 drives the support table 52 to rotate through the universal joint coupling.

[0026] In addition, in this embodiment of the application, the support platform 52 is provided with a plurality of fixed ear seats 53. The fixed ear seats 43 are used to fix the refrigerator. Specifically, the refrigerator and the fixed ear seats 43 can be connected by bolts to prevent the refrigerator from moving around randomly during shaking and opening.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
