EXAMPLES Examples of the present invention will be described below. FIG. 1 shows an embodiment of the present invention configured as one unit.

The first arm, designated by reference numeral 1 in the drawing, has its base end rotatably and horizontally rotatably via a bearing member 4 on a support shaft 3 fixed to the top of the waste oil tank 2. It is pivotally supported.

The first arm 1 is for pressing and holding a waste oil receiver 11 which will be described later on an oil discharge port b of an oil pan a, and the base end of the first arm 1 is provided with the arm 1 of the arm 1. A counterweight 5 having a sufficient mass for turning the first arm 1 upward is integrally formed against the load of members such as the second arm 7 attached to the tip, the waste oil receiver 11, and the oil recovery pipe 17. It is fixed to.

On the other hand, the above-mentioned second arm 7 is
An arm member for applying the waste oil receiver 11 attached to the tip end through the universal joint 8 to the oil discharge port b of the oil pan a. The arm 7 has a friction that can maintain a given posture. It is pivotally supported up and down with a fulcrum pin 9 at the tip of the first arm 1 with force, and the arm 7 itself is configured to be extendable and contractible with several sleeve members 7a and 7b slidably inserted therein. Has been done.

On the other hand, the waste oil receiver 11 rotatably attached to the tip of the second arm 7 is formed in a cup shape so as to be closely held on the lower surface c of the oil pan a. At the bottom of the rod, a knob 12 is provided at the lower end and a box spanner 13 is provided at the upper end so that the plug d can be removed from the outside while the waste oil receiver 11 is in close contact with the lower surface c of the oil pan a. The plug removing unit 14 is rotatably attached by a coil spring 15 while being biased in such a direction that the box spanner 13 is always separated from the plug.

One end of a waste oil recovery hose 17 extending from the waste oil tank 2 is connected to the bottom of the waste oil receiver 11,
By operating the suction pump 20 provided in the waste oil tank 2, the engine oil flowing out from the oil discharge port b is collected in the waste oil tank 2, and the waste oil receiver 1
A stopper 18 is attached to the drain oil recovery hose 17 in the vicinity of 1.
The branch hose 19 provided with the oil pan a is branched, and the tip of the branch hose 19 is inserted into the oil drain port b of the oil pan a.
The engine oil remaining inside is suctioned and removed. Reference numeral 6 in the figure indicates an auxiliary counter weight.

In the embodiment constructed as described above, in order to drain the engine oil from the automobile that has moved to one side of the draining device, the drain port b of the oil pan a is first sealed. Loosen the plug with a spanner.

Then, the second arm 7 is expanded around the fulcrum pin 9 from the folded state shown by the chain double-dashed line in FIG. 2 (a), and this arm 7 is further extended to the tip. The waste oil receiver 11 held in the above is applied to the oil drain port b of the oil pan a.

As a result, the first arm 1 receiving the upward rotational biasing force of the counterweight 5 transfers the waste oil receiver 11 to the oil discharge port b of the oil pan a from below via the second arm 2. Because it pushes up and holds it, next,
The suction pump 20 is operated to firmly adsorb the waste oil receiver 11 to the oil discharge port b, and the plug removal 14 is pushed against the coil spring 15 to engage the box spring 13 at the upper end with the plug.

When the plug remover 14 is rotated to remove the plug from the oil discharge port b, the engine oil inside the waste oil receiver 11 is absorbed by its own weight and the suction force of the suction pump 20.
It rapidly flows down into the waste oil tank 7 through the exhaust oil recovery hose 17.

When all the engine oil is drained in this way, this state is detected by a change in the rotation sound of the suction pump 20. Therefore, in such a state, the suction pump 20 is stopped and the plug is The plug held by pressing the detacher 14 is joined to the oil drain port b, and then the waste oil receiver 11 is removed from the oil pan a to complete a series of withdrawing operations. FIG. 2B shows the operation of extracting engine oil under a jacked-up state. Even in this state, the upward biasing force of the first arm 1 causes the waste oil receiver 11 to move the waste oil receiver 11 into the oil pan a. It is understood that it is held securely on the lower surface c of the.

By the way, the oil drain port b provided in the oil pan (a) is not always provided on a flat bottom surface, but in the case of a small automobile or the like, it is provided at a portion slightly offset from the bottom portion. There is a case.

In such a case, as shown in FIG. 3A, if the angle of the waste oil receiver 11 is changed so that the waste oil receiver 11 is aligned with the surface of the oil drain port b at the universal joint 8, the joint can be prepared. Similarly, the waste oil receiver 11 can be properly brought into close contact with the surface of the oil drain port b.

When the engine oil has been drained in this state, the waste oil receiver 11 is temporarily displaced near the oil discharge port b and joined, as shown in FIG. Insert the tip of the hose 19 into the oil drain port b to stop the stopper 18.
Open up.

As a result, the engine oil remaining at the bottom of the oil pan a is completely sucked by the suction action of the suction pump 20, and finally the waste oil receiver 1
1 is again moved to the oil drainage port b, and the oil drainage port b is sealed by the plug by the above-mentioned operation, and the extracting operation is completed.

In the above embodiment, the first arm 1
Although the counterweights 5 and 6 are used as means for applying an upward biasing force to the above, the counterweights may be configured to utilize the torsion of the coil spring, and the subrod may be linked to the first arm 1 in a link shape. It is also possible to provide a side-by-side configuration to apply an upward biasing force to the first arm 1 by means of a tension spring built in this sub rod. In such a case, the device can be made lighter in weight. it can.

Further, if an electromagnet is provided at the rim of the waste oil receiver 11 and the electromagnet is energized when joined to the oil pan a, the waste oil receiver 11 can be joined to the oil pan a more reliably. Can be done.

[0023]

As described above, according to the present invention, the second arm is joined to the first arm biased by the upward biasing means with a frictional force, and the tip of the second arm is further joined. Since the waste oil receiver is attached via the universal joint, simply by joining this waste oil receiver to the oil discharge port of the oil pan, the waste oil receiver can be held closely regardless of the metal that constitutes the oil pan. However, by removing the plug in this state, the oil in the engine can be easily collected without soiling clothes and the like, and this kind of work can be efficiently performed by the simple device.
