Description

Technical Field

[0002] Shotcrete machine is a kind of mechanical equipment widely used in construction, mining, tunnel and other engineering fields. The following is a detailed introduction to it: Shotcrete machine uses mechanical force to mix, transport and spray concrete or other building materials (such as mortar, etc.).

[0003] A spraying pipe is put on the discharge port of the spraying machine, and the tail end of the spraying pipe is a nozzle. Since the traditional spraying machine body is far away from the nozzle, the spraying range of the mortar sprayed by the nozzle is affected by the limitation of the motor power and cannot be sprayed very far. Since it cannot spray far, it is difficult to carry out efficient spraying operations in deep areas in large tunnel construction, which extends the construction period and increases manpower and time costs. In addition, for the exterior wall spraying projects of some high-rise buildings, it is difficult to cover higher positions and a complex auxiliary spraying platform needs to be built, which is not only inconvenient to operate but also poses a safety hazard. In order to solve the above problems, we proposed this remote spraying spraying machine. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a spraying machine capable of remote spraying includes a spraying machine body 1, a discharge pipe 2, a nozzle 3 and a mobile base 4. The lower end of the nozzle 3 is connected to a connecting pipe 8, and the mobile base 4 is provided with a pressurizing mechanism for increasing the pressure in the discharge pipe 2. The pressurizing mechanism includes an air compressor 5 arranged on the side wall of the mobile base 4. The air outlet end of the air compressor 5 is connected to an air outlet pipe 6. A flow regulating valve 12 is provided on the side wall of the air outlet pipe 6. The connecting pipe 8 is connected to the air outlet pipe 6 through a connecting mechanism.

[0023] The connecting mechanism includes a mounting tube 9 fixedly connected to the side wall of the connecting pipe 8. The mounting tube 9 is internally threaded with a connecting sleeve 10. The connecting sleeve 10 is fixedly connected to the air outlet pipe 6. A sealing ring is provided on the connecting sleeve 10, which is not shown in the figure.

[0024] In the utility model, a mounting frame 15 is provided on the side wall of the movable base 4, a threaded rod 21 is provided on the top of the mounting frame 15, a lifting plate 20 is provided on the threaded rod 21, a rotating rod 7 is provided on the side wall of the lifting plate 20, a rotating piece 14 is fixedly connected to the side wall of the rotating rod 7, a connecting piece 13 is provided on the side wall of the nozzle 3, two screws are provided on the side walls of the connecting piece 13 and the rotating piece 14, and two nuts are provided on the side walls of the screws, so that the nozzle 3 does not need to be manually supported, thereby improving the practicality of the device.

[0025] In the present invention, a first motor 16 is provided at the lower end of the mounting frame 15 , and the output shaft of the first motor 16 is fixedly connected to the lower end of the threaded rod 21 , so that the height of the lifting plate 20 does not need to be adjusted manually, thereby improving the degree of automation of the device.

[0026] In the present utility model, a second motor 18 and a reducer 19 are provided on the side wall of the lifting plate 20, and the rotating rod 7 is fixedly connected to the output shaft of the reducer 19, so that the nozzle 3 can swing up and down in a small range, thereby improving the uniformity of the mortar spraying. Two connecting plates 17 are fixedly connected to the side wall of the mounting frame 15.

[0027] In the utility model, a safety valve 11 is provided on the side wall of the air outlet pipe 6. If the shotcrete machine is started or stopped at the moment, a sudden change in pressure or flow may occur.

A pull rod is fixedly connected to the side wall of the mobile base 4.

[0028] It should be noted that the present invention is a spraying machine capable of remote spraying. The user pulls the discharge pipe 2, aligns the nozzle 3 with the area to be sprayed, and starts the spraying machine body 1 and the air compressor 5. The air compressor 5 injects compressed gas into the nozzle 3 through the air outlet pipe 7 and the connecting pipe 8, which can pressurize the mortar to be sprayed for the last time, so that the mortar is sprayed from the nozzle 3 at a higher speed and energy under the action of high pressure, thereby increasing the spraying distance. A compressed gas inlet is set near the nozzle 3, which can most directly provide additional pressure for the mortar, so that it can obtain greater kinetic energy at the moment of spraying, and the spraying effect is obvious, which is more direct and effective in increasing the spraying distance.
