Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction nozzle for sucking and collecting waste oil such as lubricating oil and grease or various wastes such as dust and mud.

[0002]

2. Description of the Related Art Conventionally, various suction nozzles for collecting waste have been used according to the characteristics of various kinds of waste. However, for highly viscous waste such as grease, it is impossible to aspirate because the inside of the suction nozzle and the hose connected to this suction nozzle are blocked by the waste, and it is still impossible. Currently, no suitable suction nozzle is provided. For this reason, highly viscous waste can be collected by scraping it with a finger or a spatula.
It is common to wipe it off with something like a waste cloth.

Further, since waste such as engine oil and transmission gear oil is discharged from the bottom of the oil pan, transmission, etc., it is made to fall out and is once collected in some container such as a saucer or can each time. Is common.

[0004] In addition, for dust-like waste such as iron rust, dust, and mud scattered on the floor surface, it is effective to sweep it with a brush and suck it. Therefore, a brush should be attached to the tip of the suction nozzle. Various shapes provided are used.
However, since these are equipped with brushes along the periphery of the opening at the tip of the suction nozzle, there is certainly an effect of brushing, but when pressed along the floor surface etc., the air between the inside and outside of the brush is However, there is a problem that the suction power of the core is reduced by interrupting the flow of.

The above-mentioned waste collection work is an indispensable work in various factories and work sites, and efficient execution of this work is an unavoidable condition for improving the overall work efficiency. Therefore, it has been urgently desired to devise and improve the current situation.

The present invention has been made by paying attention to the conventional technique and the current situation as described above, and includes a suction nozzle capable of sucking and collecting highly viscous waste and a bottom portion of an oil pan, a transmission, or the like. It is intended to provide a suction nozzle that can directly suck and collect waste that is discharged, and a suction nozzle that can suck and collect waste such as dust without reducing the suction power. is there.

[0007]

In order to solve the above-mentioned problems, a suction nozzle according to the present invention connects a suction / collection device to a connection port at a rear end and sucks waste from a suction port at a front end. In such a pipe-shaped suction nozzle, an air inlet pipe for sucking air into the suction nozzle is provided at the suction port portion. Further, the suction port portion is provided with a plurality of small holes, and at least one hose of the plurality of hoses provided in each of these small holes has a shorter length than the other hose and is also used as an air introduction tube. It is what Alternatively, the suction port has a cup-like shape and is provided with a perforated plate therein, and a substantially L-shaped air introduction tube having a front end protruding from the side wall of the cup-shaped suction port and a rear end disposed behind the perforated plate is provided. It is a thing.

Further, in the pipe-shaped suction nozzle for connecting the suction recovery device to the connection opening portion at the rear end and sucking the waste from the suction opening portion at the front end, the suction opening portion is positioned substantially in the center of the periphery thereof. The brush is installed.

[0009]

In the suction nozzle for recovering waste according to the present invention, which is provided with the air introduction pipe, while sucking the waste from the suction port, only the air is always sucked from the air introduction pipe provided in the suction port. Aspirate inside. As a result, highly viscous waste such as grease is sucked into the suction nozzle from the suction port, and the sucked waste is divided into bubbles or shreds by the flow of air sucked from the air introduction pipe. be able to. Furthermore, since there is always a flow of air inside the suction nozzle and inside the hose connected to this suction nozzle, the flow of air does not have to block this waste that has become foamy or chopped halfway. It can be collected by flowing into a collection container using the momentum of.

This suction port is provided with a plurality of small holes, each of these small holes is provided with a plurality of hoses, and at least one of these hoses has a shorter length than the other and also serves as an air introducing pipe. In this case, the suction and recovery work can be efficiently performed even for a complicatedly complicated portion.

Further, the suction port has a cup-like shape and is provided with a perforated plate therein, and the front end is projected to the side wall of the cup-shaped suction port part and the rear end is arranged behind the perforated plate. When the pipe is provided, the waste can be directly sucked and collected while the suction nozzle is arranged below the bottom of the oil pan or the transmission.

Further, in a suction nozzle for a suction / collection device in which a brush is installed at a substantially central position within the periphery of the suction port, a gap can be provided between the brush and the periphery of the suction port. Since air can be sucked through the gap without any obstruction, it is possible to efficiently suck and collect dust and the like without reducing the suction force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a suction nozzle 1 for collecting waste according to the present invention, in which a suction port 3 of a pipe-shaped suction nozzle main body 2 is inclined and a plate 4 is provided at a front end thereof.
The plate 4 has five small-diameter short tubes 5a and 5b attached thereto. The small diameter short pipes 5a and 5b are the suction nozzle main body 2
To connect the inside and outside of the hose with a long hose 6a or a short hose 6 in each of them.
b is provided. 4 small diameter short pipes 5a excluding the uppermost part
Each of the small holes 7a for sucking waste is provided with a long hose 6a. The remaining small diameter short tube 5
The small hole 7b of b also serves as an air introduction pipe, and is provided with a hose 6b having a short size. A suction port V is connected to the connection port 8 at the rear end of the suction nozzle body 2.

With such a structure, highly viscous waste such as grease is collected from the hose 6a and the small diameter short pipe 5a.
While being sucked into the suction nozzle main body 2 from the inside, the sucked waste can be divided into bubbles or chopped pieces by the flow of air sucked from the hose 6b and the small diameter short pipe 5b. Furthermore, since a flow of air can be constantly generated inside the suction nozzle main body 2 and inside the hose or the like connected to the suction nozzle main body 2, this waste in the form of foam or shreds is blocked on the way. It can be collected by pulling it into a collection container without causing it.
