する部分２ａを有する。As shown in FIG. 3, a plurality of sets of four force idle rollers 10 for guiding the upper belt 2 of the belt conveyor 5 are attached to the frame 6 provided in the belt conveyor support lug 21. When the upper belt 2 passes through the area surrounded by these rollers 10, the upper belt 2 is bent into a pipe shape and the soil 1 is
An earth and sand transport space 9 is formed which can hold the earth and sand. At this time, both end portions of the upper belt 2 have portions 2a that overlap with each other.
また、ベルトコンベア５の下側ベルト３は、図示しない

に屈曲されるにしたがって、土砂１は速やかに土砂搬送
スペース９に抱持される。Since the earth lifting device of the dredger of the present invention is configured as described above, when the bucket 24a reaches the upper position, the soil 1 excavated by the packet wheel 24 is transferred from the bucket 24a to the upper belt of the belt conveyor 5. It falls on the 2nd end. The upper belt 2 is connected to the drive pulley 4
Since the upper belt 2 is bent into a pipe shape by the guide roller jO, the earth and sand 1 is quickly held in the earth and sand transport space 9.
また、ひれ７が土砂搬送スペース９内に残留する水によ
る土砂１の逆流を防止するため、土砂１は、上側ベルト
２との間においてすべることなく、船体２０上へ揚土搬
送される。In addition, since the fins 7 prevent backflow of the earth and sand 1 due to water remaining in the earth and sand transport space 9, the earth and sand 1 is lifted and conveyed onto the hull 20 without slipping between it and the upper belt 2.
さらに、土砂搬送スペース９内の土砂１は、パイプ状に
屈曲した上側ベルト２の両側端部が相互に重合する部分
２ａを有しているため、周囲の海水からシールされる。Further, the earth and sand 1 in the earth and sand transport space 9 is sealed from surrounding seawater because the pipe-shaped upper belt 2 has portions 2a where both ends thereof overlap with each other.
このように、ベルトコンベア５により土砂１を揚土搬送
できるため、大馬力の浚渫ポンプあるいはパケットコン
ベアを支持する大型のラダーを必要とせず、船体２０を
小型・軽量化できる。In this way, since the earth and sand 1 can be lifted up and transported by the belt conveyor 5, there is no need for a large-horsepower dredging pump or a large ladder to support a packet conveyor, and the hull 20 can be made smaller and lighter.
また、ひれ７により、土砂１と共に搬送される水の逆流

２０．Ｊニへ確実に揚土搬送される。In addition, the fins 7 do not allow the backflow of the water conveyed with the earth and sand 1, and prevent the earth and sand 1 from flowing back, so the volumetric efficiency of the earth and sand 1 in the earth and sand transport space 9 is increased, and the hull
The earth and sand 1 can be made smaller and lighter, and even if the earth and sand 1 are tilted steeply, the earth and sand 1 will be carried over to the hull 20. The soil will be reliably transported to J.
さらに、浚渫部付近の土砂搬送スペース９の入口におい
て土砂１か逆流することかなく、バケントホイール２４
からの土砂１の受は渡しか円滑に行なわれる。Furthermore, the bagent wheel 24 can prevent the earth and sand 1 from flowing backward at the entrance of the earth and sand transport space 9 near the dredging part.
The receiving of earth and sand 1 from the river is carried out smoothly.
一方、土砂搬送スペース９内における土砂１は周囲の海
水からシールされるので、土砂１が土砂搬送スペース９
から逃げることかなく、搬送効率を著しく高めることが
できるのである。On the other hand, since the earth and sand 1 in the earth and sand transport space 9 is sealed from the surrounding seawater, the earth and sand 1 are transported to the earth and sand transport space 9.
This makes it possible to significantly improve conveyance efficiency without escaping.

き、小さな動力で揚土移送が行なえるのである。As described in detail above, the dredger's soil lifting device of the present invention is provided with a soil transport section that transports earth and sand from the dredging section to the hull and lifts the soil, and the soil transport section or the belt conveyor and the same belt convey the soil from the dredging section to the hull. The conveyor is composed of a plurality of guides that guide and bend the upper belt part of the conveyor into a pipe shape, and the earth and sand can be held and conveyed inside the pipe-shaped upper belt part. With an extremely simple configuration in which a transport space is formed, it is possible to transport the soil using a belt conveyor, so the dredger can be made smaller and lighter, and the soil can be transported with less power.

とができ、海洋汚染の防止に寄与しうる利点もある。In addition, the sealing properties between the earth and sand and the surrounding seawater are good, and the earth and sand do not escape from the earth and sand transport space formed by the upper belt, which is shaped like I#. It also has the advantage of being able to prevent the scattering of earth and sand, contributing to the prevention of marine pollution.
