されていく工程を示している。 FIG. 1 shows an overall side view of an asphalt finisher, in which asphalt mixture 2 is supplied into a hopper 1 by a dump truck and is screeded by a bar conveyor device 3 and a screw conveyor device 5 installed behind a tractor 4. This shows a process in which the screeding device 6 spreads and supplies the material to the front of the device 6, and as it progresses to the left, the paving strip M having the required thickness is formed by the screeding device 6.

る。 Further, FIG. 2 shows an overall plan view, and the screed device 6 is composed of a main screed 7 and an auxiliary telescoping screed 8. There are mixer gates 9 on the left and right sides of the main screed 7, and gates 9 on the left and right sides of the auxiliary telescoping screed 8. Side plates 10 are attached to the left and right sides. The main screed 7 is fixed, but the auxiliary telescopic screed 8
has a structure that allows it to expand and contract arbitrarily in the left and right directions.

の表面欠陥を生成する要因となる。 FIG. 3 shows the auxiliary telescoping screed 8 when it is fully extended, and the amount of mix material supplied to the front side of the auxiliary telescoping screed 8 is limited by the mix material gate 9.
As shown in FIG. 2, the auxiliary telescopic screed 8 extends beyond the composite material gate 9, and the gap l2 portion formed between the outer end of the composite material gate 9 and the side plate 10 has a ground clearance shown in the cross section of FIG. h 2 is supplied, and the effective length l of the mixture gate 9 is equal to the ground height of the mixture gate h 1
(Figure 4). For this reason,
In the part l 1 with the composite material gate 9 and the part l 2 without,
The amount of mixed material supplied to the front part of the auxiliary telescopic screed 8 becomes uneven, and the large amount of mixed material supplied from the gap part l2 forms a cooled and solidified stagnation part Z in the front part of the auxiliary telescopic screed 8, The pavement M
This causes surface defects.

して逃がす必要があるが、合材の無駄になる。 Furthermore, when the auxiliary telescopic screed 8 is contracted, the accumulated material in the above-mentioned accumulation section Z gets caught between the main screed 7 and the side plate 10, significantly interfering with the operation. Alternatively, it is necessary to pull up the side plate 10 to release it, but this results in waste of composite material.

面を総て覆うものである。 Therefore, the purpose of this study is to provide a telescoping composite material gate for asphalt finishers that eliminates the above-mentioned drawbacks. This is a synchronized telescoping composite material gate, which is attached to the front surface of the auxiliary telescoping screed, and covers the entire front surface of the auxiliary telescoping screed.
本考案の実施例を以下図面に従つて詳細に説明

The telescoping gate 18 is provided with a mixture adjustment plate 11 that controls the amount of inflow mixture using an adjustment bolt 12. Further, the connecting pipe 13 is inserted into the guide pipe 17 welded to the composite material gate 18 and fixed with a pin 15. or,
The other end of the connecting pipe 13 is inserted into a square pipe 16 with a hole so that it can be slid up and down.

出することができる。 Next, to explain its function and effect, FIG. 7 shows the construction state of a finisher equipped with this telescoping gate. The telescoping gate 18 attached to the strike-off of the main screed 7 is connected to the auxiliary telescoping screed 8 via the connecting pipe 13 and the square pipe 16. Slide. In this way, the telescoping gate 18 covers the entire front surface of the auxiliary telescoping screed 8, so that the spread and supplied composite material 2 is spread all over the auxiliary telescoping screed 8 to the height of the ground height h 1 of the material amount adjustment plate 11. Since it is regulated and supplied uniformly, it is possible to form a layer with a constant density at all times. For this reason, the accumulated material G that has cooled and solidified is not generated. In this way, a smooth mixture flow is obtained on the lower surface of the auxiliary elastic screed 8, and a dense and elegant paving belt M can be produced.

前部に供給する合材量は、舗装帯Ｍの所要の厚さ
に合せて必要量に規制できる。即ち第７図のh1は
任意に変えられる。 Since the height of the mixed material amount adjustment plate 11 can be adjusted using the adjustment bolt 12, the amount of mixed material supplied to the front part of the auxiliary telescopic screed 8 can be regulated to the required amount according to the required thickness of the paving strip M. . That is, h 1 in FIG. 7 can be changed arbitrarily.

る。 When controlling the vertical adjustment H of the auxiliary telescopic screed 8, the square pipe 16 is fixed to the auxiliary telescopic screed 8, so it moves in sync with the amount of adjustment.
Since the connecting pipe 13 is structured to be able to slide along the hole in the square pipe 16, the auxiliary telescopic screed 8 can operate independently of the composite material adjustment plate 18.

帯を形成出来る。 In short, according to the present invention, a telescopic screed is provided to be able to expand and contract in the left and right direction, and a telescopic gate is provided to be movable in the same direction as to cover the front surface of the telescopic screed, and a height is adjusted at the bottom of the telescopic gate. By being equipped with an adjustment plate that can be installed to cover the front surface of the telescopic screed, the material gate expands and contracts in synchronization with the expansion and contraction movement of the telescopic screed, making it possible to adjust the amount of material attached to the telescoping gate. The amount of mixed material supplied by the plate can be adjusted arbitrarily. The telescoping gate and the square pipe are connected by a connecting pipe, so there is no difference in the level of the auxiliary telescoping screed (up and down).
When adjusting, the square pipe can be slid along the connecting pipe to adjust the amount of vertical adjustment. In this way, the asphalt mixture can be uniformly supplied to the front surface of the auxiliary screed part, the asphalt mixture can be accumulated in an appropriate amount between the mixture gate and the front surface of the auxiliary screed, and a dense and elegant pavement belt can be formed.
