Furthermore, an operating handle is arranged on the oil delivery pipe.

Furthermore, operating handle includes first operating handle and second operating handle, the axis of first operating handle and the axis of second operating handle all with the axis of defeated oil pipe is perpendicular, the axis of first operating handle is parallel with the axis of second operating handle.

Further, the inlet of the oil delivery pipe is connected with a high-pressure ball valve, and the high-pressure ball valve is connected with a hose.

Further, the oil outlet pipe and the oil delivery pipe are welded and fixed.

The beneficial effects of the utility model reside in that:

1. the utility model has the advantages that the utility model can be used without manually rolling grease or using bamboo chips, and only the flat pipe in duckbill shape at the front end of the device is inserted between the steel wire brushes, and the grease pump is adopted to pump the grease, so that the grease filling mode is more uniform, full and compact than manual filling, and full filling from inside to outside can be realized;

2. the utility model adopts the oil pump to be matched with the oil delivery pipe and the oil outlet pipe to fill oil to the shield tail brush, has high automation degree, and avoids the environmental pollution problem caused by manual oil filling in the prior art;

3. the utility model discloses need not manual group's shield tail grease, and then can effectively practice thrift the consumption of shield grease.

Furthermore, the utility model relates to a principle is reliable, and simple structure has very extensive application prospect.

In the figure, 1 is an oil outlet pipe, 1.1 is a flat pipe, 1.2 is a circular pipe, 2 is an oil delivery pipe, 3 is a first operating handle, 4 is a second operating handle, and 5 is a high-pressure ball valve.

Detailed Description

In order to make the technical solutions in the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

The utility model provides a device is gone into to shield tail grease pump, is including the defeated oil pipe 2 that is used for carrying shield tail grease, oil pipe 1 is installed to the one end of defeated oil pipe 2, defeated oil pipe 2's the other end passes through the hose and is connected with the grease pump. When the device works, shield tail oil is added into the grease pump, the grease pump is started, and the shield tail oil is conveyed into the oil outlet pipe 1 through the oil conveying pipe 2 by the grease pump. The first operating handle 4 and the second operating handle 5 are manually held, and shield tail oil is coated on a proper position of a shield tail brush under the condition that the grease pump continuously supplies the shield tail oil.

The oil outlet pipe 1 is a hollow structure, and in order to realize tight connection with the oil outlet pipe 1, one end of the oil outlet pipe 1 is a circular pipe 1.2 and is fixedly connected with the oil delivery pipe 2, in the utility model, the circular pipe 1.2 is fixed with the oil delivery pipe 2 by welding; in order to be able to scribble the grease evenly on the shield tail brush, the utility model discloses well middle part and the other end of going out oil pipe 1 are the flat pipe 1.1 that is duckbilled, and the width of flat pipe 1.1 is crescent from the middle part to the tip, and the maximum width should slightly be less than or equal to the width of shield tail brush, like this when scribbling the shield tail brush, can once fill full.
