Description

[Detailed description of the invention] "Industrial application field" This invention is suitable for asphalt pavement road construction.
This invention relates to an improvement in a repair leveling machine that is most suitable for use in leveling roads attached to both ends while forming them.

``Prior art'' As shown in Figure 4, this type of leveling machine that has been used in the past is simply a handle part B attached to a plate part A made of iron or wood. The leveling surface is flat or in the shape of a rake, and when asphalt paving work is done on roads, it is used to flatten areas that have collapsed or are uneven after being used by a finishing machine, or where it is too narrow to use heavy machinery. In some places, it is used for paving work while being coated with oil to prevent asphalt from adhering.

``Problem that the invention aims to solve'' This type of leveling machine generally applies oil to the plate part when leveling heated asphalt, but the oil quickly comes off. , Asphalt adheres to the leveling board, making it impossible to work. Therefore, the work is carried out by frequently applying oil and removing asphalt that has adhered to it.
This had the disadvantage of wasting time and reducing work efficiency. In addition, because conventional leveling boards are fixed, they cannot be replaced even if they wear out, the width is inappropriate, or you want to change the leveling method such as a rake shape. There was the inconvenience of having to prepare several leveling machines as spares. Furthermore, since leveling machines are often operated on roads with heavy traffic, with one-way traffic restricted, it is desirable that the operating handle be able to be extended and retracted if possible. The purpose of the present invention is to solve the above problems.

"Means for Solving the Problems" The pavement leveling machine according to the present invention consists of a leveling machine body and a leveling plate body that is detachably attached to the leveling machine body.

The main body of the leveling machine has a mounting groove frame having a core material fixed to the tip of a long operating handle in a T-shape, and an oil tank is provided, and the interior of the oil tank and the core material of the mounting groove frame are A mounting body is provided on the operating handle or the oil tank at a position slightly in front of the mounting groove frame.

Further, the leveling plate is made up of a plate-like body having a leveling surface on the lower side, and a mounting plate protruding from the center of one side thereof.

The leveling plate body is attached to and detached from the mounting groove frame portion of the leveling machine body through the mounting body and the mounting plate so that its upper end contacts the core material and the leveling surface of its lower end faces downward. It can be installed freely.

The oil contained in the oil tank permeates into the core material of the mounting groove frame and is gradually supplied to the surface of the plate-like body through this core material over a long period of time.

In the pavement leveling machine having the above configuration, as shown in FIG. Alternatively, as shown in Fig. 6, the operating handle and the oil tank may be formed separately, and a mounting groove frame attached to the tip of the operating handle may be used. An embodiment may be adopted in which the oil tank is connected to the oil tank for communication through a pipe. At this time, an oil supply adjustment mechanism may be provided at a suitable location in the oil tank or pipe so that the oil supply can be stopped or taken out as necessary.

Furthermore, it goes without saying that the operating handle of the pavement leveling machine according to the present invention may be configured to be extendable and retractable.
