DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortar filling machine for filling mortar into joints in masonry of concrete blocks or bricks.

[0002]

2. Description of the Related Art In masonry of concrete blocks, bricks, and the like, joints are filled with mortar exclusively using a joint trowel. However, filling mortar to joints requires skill,
A craftsman who is unfamiliar with the work has a problem that the work efficiency is low and a satisfactory finished state cannot be obtained.

[0003] Further, a mortar is packed in a conical bag made of synthetic resin, and the mortar is squeezed out from a hole at the tip of the bag to fill the joint portion with the mortar.
However, this method also has a drawback in that the filling amount of the mortar varies depending on the amount of squeezing during squeezing, and a good finish cannot be obtained.

To solve such a problem, a filling machine as described in Japanese Utility Model Publication No. 7-43350 is known. In this filling machine, a hose with a nozzle with a cock attached to the tip is detachably connected to the discharge port of the pressure pump. According to this filling machine, the mortar discharge amount is always controlled to a constant amount, It is said that there is an effect that the joint filling work can be performed even if it is not a person.

[0005]

However, the filling machine described in the above publication has a pump having a complicated structure, a driving device with a control operation panel, and a hopper mounted on a truck.
As a whole, it is a large-scale device, the cost of the device is high, and the transportation to the construction site and the movement of the work place are troublesome, so that it is difficult for a small-scale construction company to adopt it.

An object of the present invention is to reduce the size of a mortar filling machine, to obtain a mortar filling machine which is inexpensive and which can be easily transported to a construction site or moved to a work place.

[0007]

According to the mortar filling machine of the present invention, a shaft having fins attached to the outer periphery is connected to a rotating shaft of a hand-held electric rotating machine, and a mortar container including the shaft is electrically driven. The mortar container is provided with an opening for extruding mortar at a position of a tip end portion of the shaft body. Here, the electric rotating machine may be cordless by incorporating a battery therein.

The mortar in the container is pushed out from the opening by the rotation of the shaft having the fins attached thereto, so that even a non-expert can push a certain amount of mortar toward the joints, resulting in a clean finish. Mortar filling can be performed efficiently. In addition, since the entire mortar filling machine including the mortar container can be held by hand, not only can it be transported to the construction site, but also the work place can be easily moved, and if the battery is built in the electric rotating machine and it is cordless, In addition, the mortar filling operation can be performed even in a place where there is no power supply.

A vibrating member that vibrates in contact with the fins of the shaft can be attached inside the mortar container. If one end side of this vibration member is fixed to the container body and the other end side is in contact with the fin of the shaft, the vibration member vibrates by contacting the fin rotating with the shaft,
Vibrating the mortar in the container facilitates extruding the mortar from the opening.

[0010] The mortar extrusion opening may be formed so as to be directed in a direction parallel or orthogonal to the axial direction of the shaft body. For example, when constructing a fence by assembling blocks, hold the mortar filling machine horizontally so that the axial direction of the shaft of the mortar filling machine is parallel to the surface of the fence, and place the mortar on the top block. When filling
The opening for mortar extrusion may be directed downward in a direction perpendicular to the axial direction of the shaft body. In addition, when the mortar filling machine is horizontally held in a direction in which the axial direction of the shaft of the mortar filling machine is perpendicular to the surface of the fence and the mortar is filled on the uppermost block, the opening for mortar extrusion is: If the mortar filling machine is moved to the right or left in parallel with the surface of the fence, the mortar will be pushed out of the opening if the opening is directed to the left or right at right angles to the axial direction of the shaft. Is cleanly packed on the block. Also, when the mortar filling machine is vertically held in a direction in which the axial direction of the shaft body of the mortar filling machine is parallel to the surface of the fence and the mortar is filled on the uppermost block, the opening for mortar extrusion is: The opening may be directed to the left or right at right angles to the axial direction of the shaft body. By giving the direction of the mortar extrusion opening in this way, mortar suitable for the posture of the filling machine at the time of mortar filling can be extruded.

Here, when the mortar extruding opening of the mortar filling machine is brought into contact with the mortar filling portion such as a block, the mortar filling machine can be stably held. It is desirable to attach a buffer member to the opening for mortar extrusion. As the cushioning member, natural rubber, synthetic rubber, or the like can be used.
