Parallel link mechanisms 7 and 1 are attached to the housing 9 and the diaphragm 13.
2, a hydraulic cylinder 14 connected via 2; an opening / closing device 17 for opening and closing a lower end opening of the housing 10; and a hydraulic cylinder 18 for driving and controlling the opening / closing device 17. It should be noted that the numbers added to the above-mentioned configurations are for comparison with the drawings in order to facilitate understanding of the present invention, and the configurations of the present invention are not limited thereby.

[0005]

In the present invention, during the mortar leveling work, the mortar leveling mechanism 6 is lowered to bring the vibration plate 13 into contact with the piecing surface, as shown in FIG. While moving 2 to the right in the figure, press the hydraulic cylinder 1
The size of the opening of the opening / closing device 17 is adjusted by 8, the mortar is sprinkled out, and the vibrating plate 13 rubs in and smoothes the mortar.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of a mortar leveling device of the present invention, FIG. 1 (A) is a side view showing a state during movement, and FIG. 1 (B) shows a state during leveling. Side view, Figure 2
1 is a front view of FIG. 1, FIG. 3 is a partial side view showing a state of mortar supply, and FIG. 4 is a cross-sectional view taken along the line YY of FIG.

In the figure, the mortar leveling device 1 is
The traveling carriage 2, the caterpillar 3 provided under the traveling carriage 2, the driver's seat 4 and the operation lever 5 provided on one side of the traveling carriage 2, and the mortar spreading mechanism 6 provided on the other side of the traveling carriage 2. It consists of

The mortar leveling mechanism 6 is a frame 8 attached to the traveling carriage 2 via a parallel link mechanism 7.
A hopper 9 fixed to the upper part of the frame 8, a housing 10 fixed to the lower part of the frame 8, three pipes 11 connecting the hopper 9 and the housing 10, and a parallel link mechanism to the lower part of the frame 8. A vibrating plate 13 attached via 12 and a vibrating machine 1 for vibrating the vibrating plate 13.
3a.

The parallel link mechanism 7 is operated by a hydraulic cylinder 14, and by the action of the two parallel link mechanisms 7 and 12, the hopper 9 and the vibrating plate 13 can be moved up and down while maintaining the horizontal state, and as a result, as shown in FIG. As shown in FIG. 1 (A), the mortar leveling mechanism 6 is in a raised state during movement, and as shown in FIG. 1 (B), the mortar leveling mechanism 6 is moved.
Is lowered, and the vibration plate 13 can be switched to the state in which the diaphragm 13 is grounded.

As shown in FIG. 4, an opening / closing valve 15 is disposed inside the hopper 9, and the opening / closing valve 15 is drive-controlled by a hydraulic cylinder 16 to pipe the mortar filled in the hopper 9. 11 through housing 10
It is possible to supply to.

The lower end of the housing 10 is open,
An opening / closing device 17 for opening and closing this opening is provided. The opening / closing device 17 is drive-controlled by a hydraulic cylinder 18, and has a state in which the opening of the housing 10 is closed as shown in FIG. 3 (A) and a size of the opening of the housing 10 as shown in FIG. 3 (B). It is possible to adjust and switch to a state where the mortar is sprinkled.

The spreading and leveling work of the present invention having the above structure will be described. During the mortar leveling operation, mortar is supplied from the mixer to the hopper 9, and the mortar leveling mechanism 6 is lowered to ground the vibrating plate 13 on the joint surface, as shown in FIG. 1 (B). Next, while moving the traveling carriage 2 to the right in the figure, the size of the opening of the opening / closing device 17 is adjusted by the hydraulic cylinder 18, and the mortar is sprinkled out.
The vibrating plate 13 rubs in and smoothes the mortar. When the mortar leveling at the corresponding place is completed and the mortar is moved to the next position, the openings of the hopper 10 and the opening / closing device 17 are closed, and the mortar leveling mechanism 6 is raised as shown in FIG. 1 (A). Let me move.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above embodiment, the hopper 9 is filled with mortar, but a hose may be connected to the pipe 11 and the mortar may be directly supplied by a pump.

[0014]

As is apparent from the above description, according to the present invention, a traveling carriage, a housing and a vibration plate arranged to be movable up and down on the traveling carriage, and a parallel link mechanism for the housing and the vibration board are provided. Since it is configured to include a hydraulic cylinder connected through the opening / closing unit, an opening / closing device for opening / closing the lower end opening of the housing, and a hydraulic cylinder for driving / controlling the opening / closing device, labor saving of mortar spreading work is reduced. And work efficiency can be improved.
