Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spraying machine for spraying construction materials such as rock wool onto steel frames, walls, etc.

The spraying material used in conventional spraying work is made by pre-mixing the main fibrous material, such as rock wool, bulk cotton, glass wool, etc., with an additive material for coagulation, adhesion, etc., such as cement. Therefore, there was no need to manufacture the spraying material at the work site or adjust the mixing ratio of its composition.

However, if the spray material is manufactured at a predetermined mixing ratio in this way, it is difficult to obtain the optimal spray material at the spraying site, and it is also possible to change the spray material depending on changes in the spraying location. There is a disadvantage of not being able to do it.

The present invention aims to provide a spraying machine that can eliminate the above-mentioned disadvantages.

The spraying machine of the present invention will be explained below with reference to the attached drawings. In Fig. 1, 1 is a moving frame, 2 is a feeding mechanism, 3 is an addition section, and 4 is a
5 is a water pump, 5 is a compressor, 6 is a motor as a driving means, 7 is a blowing device such as a fan-type blow, roots blow, or compressor provided in the sending section 21 of the sending mechanism 2, and 8 is a discharge hose for sending the material to be sprayed. 9 is an injection nozzle provided at the tip of the hose 8, 10 is a water supply hose that supplies water from the water pump 4 to the nozzle 9, 11 is an air supply hose that supplies air from the compressor 5 to the nozzle 9, and 12 is a spray main. The material is made of a fibrous material or mixed with other materials, and is supplied from the supply port 22 of the feeding mechanism 2.

The adding section 3 is between the sending section 21 of the sending mechanism 2 and the nozzle 9, and adds powdery additive material 13 to the spray main material 12 sent out from the sending mechanism 2, as described below. It is composed like this.

The spray damage material 12 may be a fibrous material alone, a commonly used spray material, or a mixed material excluding only a specific material such as cement.

The additive material 13 may be any material that supplements, improves, or changes the composition of the main spray material 12, and may be selected from cement, vermiculite, barite, special fibers, etc. depending on the purpose.

The feeding mechanism 2 may be a fixed-quantity feeding mechanism that is conventionally known in this type of spraying machine, such as the mechanism described in Patent Publication No. 30342 of 1972, and in the embodiment, as shown in FIG. A metering feed mechanism in which 23, 24, and 25 are arranged side by side is used.

The addition unit 3 is configured to be able to adjust the feed amount to a desired value and to feed the additive material 13 in a fixed amount, and may be configured in the same manner as the feed mechanism 2, or may be configured as shown in FIG. A valve mechanism as shown may also be used.

This addition part 3 is designed to be fixedly attached to the mechanism 2 as usual, but depending on the case, it may be constructed so that it can be attached to and detached from the feed mechanism 2. In this way, one addition part can be attached to a plurality of feed mechanisms 2. There is an advantage that 3 can be shared.

Since the addition section 3 is normally configured to add the additive material 13 to the delivery section 21 of the delivery mechanism 2 as shown in FIG. 1, it does not require its own blower.
For example, as shown in Fig. 2A, the additive material 1 is placed in the middle of the discharge hose 8.
3, it is desirable to provide a small blower 3a.

Further, the addition section 3 may add the additive material 13 to the main material 12 to be sprayed in the delivery section 21 of the feeding mechanism 2 or the discharge hose 8, and therefore may be placed before the blower 7 as shown in FIG. Alternatively, it may be placed after the blower 7 as shown in FIG. 2, but if a mixing means 3b is provided separately from the blower 7 as shown in FIG. 2B, the additive material 13 can be sufficiently sprayed into the main material 12. It can be mixed into.

Since the spraying machine of the present invention is as described above, the feeding mechanism 2
A desired amount of additive material 13 is mixed with the main material 12 to be sprayed from the additive section 3 and sprayed from the nozzle 9. At the same time, as a spray water supply means, the water sent from the water supply hose 10 is atomized with the compressed air of the air supply hose 11. It is possible to supply water to the discharged material by spraying it.

Therefore, by using the spraying machine of the present invention, it is possible to adjust and change the component ratio of the spraying material at the spraying site and during the spraying operation, or to create a spraying material by adding new components to the main spraying material. There is.
