Description

Remote wet-type slurry spraying machine under coal mine

Technical Field

The utility model belongs to the technical field of patching machine, concretely relates to remote wet-type patching machine in pit in colliery.

Background

The traditional underground wet-type shotcrete machine is low in price at present, the guniting distance is basically between 30m and 70m, the guniting distance is very limited, equipment needs to be frequently moved, a guniting material stacking point needs to be moved, underground guniting operation is severely limited, and production efficiency is low. The guniting distance of the novel remote guniting machine is mostly more than one hundred meters, but the novel remote guniting machine is very expensive, the price is basically more than several times or even more than dozens of times of that of the traditional guniting machine, the later maintenance cost is high, and the novel remote guniting machine is not in line with the concept of cost saving and consumption reduction.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve traditional patching machine guniting distance in the pit short, problem that the efficiency of construction is low realizes the purpose of festival branch consumption reduction.

Further provides a long-distance wet-type guniting machine under a coal mine, which comprises a guniting machine, wherein an air inlet and a guniting pipe are arranged on the guniting machine, a tee joint is connected to the air inlet, and a booster is arranged at the tail end of the guniting pipe; the booster comprises a spray pipe parallel to the spraying direction and connected with a guniting pipe and a branch pipe obliquely arranged on the spray pipe, and the branch pipe is communicated with the air compressor through a third air pipe. The three-way is communicated with the air compressor through a first air pipe and a second air pipe.

The air is fed into two joints of the tee joint, and the air is discharged from one joint, so that the guniting distance is increased by increasing the air inlet amount; meanwhile, the tail end of the guniting pipe is continuously connected with a booster, and the guniting distance is increased by using a high-pressure wind boosting mode.

Further, the length of the guniting pipe is 30-70 m, and the booster is connected with the guniting pipe through a buckle.

Be different from prior art, the utility model discloses at least, include following beneficial effect:

1. colliery is remote wet-type patching machine in pit, be applicable to all whitewashing construction engineering in the pit, through installation remote whitewashing boost motor and increase patching machine intake, reach extension whitewashing distance, reduction equipment moves, reduces intensity of labour's purpose, saves the expense of purchasing remote patching machine to reach the final purpose of festival expenditure reduction in consumption.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Drawings

Fig. 1 is a schematic structural view of the remote wet-type slurry spraying machine in the coal mine.

In the figure: 1. the device comprises an air compressor, 2, a guniting machine, 201, a guniting pipe, 202, an air inlet, 3, a tee joint, 4, a booster, 401, a branch pipe, 5, a first air pipe, 6, a second air pipe, 7 and a third air pipe.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the long-distance wet shotcrete machine for the underground coal mine comprises a shotcrete machine 2, wherein an air inlet 202 and a shotcrete pipe 201 are arranged on the shotcrete machine 2, a tee joint 3 is connected to the air inlet 202, and a booster 4 is arranged at the tail end of the shotcrete pipe 201; the booster 4 comprises a spray pipe parallel to the spraying direction and connected with the guniting pipe 201 and a branch pipe 401 obliquely arranged on the spray pipe, and the branch pipe 401 is communicated with the air compressor 1 through a third air pipe 7. And the tee joint 3 is communicated with the air compressor 1 through a first air pipe 5 and a second air pipe 6.

The length of the guniting pipe 201 is 30-70 m, and the booster 4 is connected with the guniting pipe 201 through a buckle.

The patching machine is used for spouting the concrete in the pit and consolidate to the tunnel, and the air compressor machine is installed on ground, needs the air compressor machine to continuously supply air in the pit, so the patching machine that this application provided communicates with 3 tuber pipes of air compressor machine simultaneously, and the homoenergetic obtains sufficient wind-force.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application suitable for this invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details shown and described herein without departing from the general concept defined by the claims and their equivalents.
