れる防塵式伸縮シユートの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is installed at the tip of the boom of a bulk cargo loading machine such as a loader or stacker, and is capable of handling bulk materials without scattering dust around them when the bulk materials are stowed in a ship hold or storage yard. This invention relates to improvements to dust-proof telescopic chutes used for stowage.

ず、積付能率が非常に悪いという欠点があつた。 The conventional dust-proof telescopic chute 4' of this type has the first,
As shown in Figures 2 and 3, there is a telescopic chute 5', a cylindrical hood 8' provided on a lower chute constituting the telescopic chute so as to surround the lower end of the lower chute, and a cylindrical hood 8' that covers the telescopic chute. It consists of a bellows whose upper end is connected to the wind pipe 7' extending from the dust collector 6' on the traveling machine body 2', and whose lower end is connected to the hood 8', and is suitable for stacking bulk materials. At the same time, the dust generated when the bulk materials are put in is collected by suction into the dust collector 6' through the hood 8' → bellows 9' → wind pipe 7', and a predetermined amount of bulk materials is stacked while preventing dust from scattering. When the pile is reached, the chute 5' and hood 8' are sequentially pulled up to form a pile, and when the pile reaches a predetermined height, the loading of bulk materials is stopped and the lower ends of the chute 5' and hood 8' are pulled up from the top of the pile. At the same time, the machine body 2' is moved to the next stowage position, and then the chute and hood are placed on the floor again, and the loading of bulk materials is resumed, stowing at a fixed point for each pile. In this conventional device, when changing the loading point, the hood must be pulled up above the top of the pile in advance, otherwise the conical pile will become an obstacle and the truck will not be able to move. If bulk materials are being thrown in when the hood is pulled up, a large amount of dust will leak out from the bottom of the hood and be scattered around. For this reason, when changing the loading point, loading of bulk materials must be interrupted, resulting in a drawback that loading efficiency is extremely poor.

A double hood with a chevron-shaped cutout with the lower ends facing in the same direction as the horizontal movement direction of the telescopic chute is attached to the lower end of the lowest chute to prevent dust leakage under continuous dropping of bulk materials. The present invention aims to provide a dust-proof telescopic chute that allows continuous stacking by sequentially changing the stacking point in the horizontal direction.

で粉塵の漏出は起らない。 Since the present invention is constructed in this way, the loading of bulk materials into the ship's hold can be carried out continuously while changing the loading point sequentially in the traveling direction without leaking dust. That is, bulk goods delivered from the ground conveyor to the loader via the tripper are stowed in the ship's hold via the boom conveyor 11 -> the chute 10 -> the telescopic chute 5. Dust generated by dropping bulk materials is captured by the inner hood 23, and dust that has penetrated the accumulated bulk materials and leaked out of the inner hood 23 is captured by the outer hood 24, and is captured by the communication hole 25 of the inner hood 23.
It passes through the inner hood and joins with the dust trapped in the inner hood to form a bellows 9.
→It passes through the wind pipe 7 and is collected by the dust collector 6. When loose materials are thrown into the hood 8 at an angle of repose or higher, the excess loose materials push open the flexible hoods 26 and 27 at the lower end of the inner (outer) hood and flow out into the surroundings. When the pile height in the hood exceeds a predetermined amount, the level detectors 30 and 31 attached to the hood wall are activated by the pile, and this signal causes the loader to continuously drop bulk materials until the level detector becomes inactive. The main body 2 is driven and the loading point is changed to the horizontal direction (travel direction). When changing the stacking point, the lower ends of the hood are both cut into a mountain shape facing in the same direction as the horizontal movement direction of the telescopic chute, so the running resistance from the stack is extremely small and the hood can be easily run. Due to the slight overlap between the slope of the pile of bulk materials and the lower end of the hood and the flexible hoods 26 and 27 installed vertically at the lower end of the hood, there is no gap between the two and the inside of the hood 8 is in a negative pressure state, so that no dust is generated. No leakage will occur.
尚、積付点が走行方向に変更される際、バラ物
落下点を境にして前方側における積山量が後方側
積山量より少ないのでバラ物落下点前方側におい
て積付けられたバラ物を貫通して内フード23の
外に粉塵が吹出ることがある。 In addition, when the loading point is changed to the traveling direction, the amount of piled items on the front side of the bulk material drop point is smaller than the amount of piled material on the rear side, so the load will pass through the bulk items stacked on the front side of the bulk material drop point. As a result, dust may blow out of the inner hood 23.
しかし、この粉塵は外フード24にて捕捉され
吸引捕集されるので粉塵漏出は生じない。 However, since this dust is captured by the outer hood 24 and collected by suction, no dust leakage occurs.
バラ物連続投下状態のもとでシツプローダの走
行によつて船艙の端から他端に向けて積付点を順
次変え乍らバラ物を積付けてゆき、船艙の他端に

位置までウインチ操作でフード8と下部シユート
21とを引上げ、続いてシツプローダを反転走行
させてバラ物を積付けてゆく。以後同操作を繰返
して行なう。 Under continuous dumping of bulk materials, the loading point is sequentially changed from one end of the hold to the other as the loader runs, and the level is detected when the loader reaches the other end of the hold. The hood 8 and lower chute 21 are pulled up by a winch operation to a position where the containers 30 and 31 are inactive, and then the loader is reversed to stack loose items. Repeat the same operation thereafter.
以上の操作の結果、船艙内には連続したバラ物
山が積付けでき、又、バラ物投入は連続して行な
えるので時間当りの積付能力は従来装置に比べ著
るしく向上できる。 As a result of the above operations, a continuous pile of bulk materials can be stowed in the ship's hold, and the loading of bulk materials can be performed continuously, so that the stowage capacity per hour can be significantly improved compared to conventional systems.
尚、船艙に対し積付けを開始した頭初フード内
にバラ物積山ができるまでのわずかの間粉塵漏出
を生じるが、漏出時間が極めて短かいのでほとん
ど問題にならない。 Incidentally, dust leakage occurs for a short time until a pile of loose materials is formed in the hood at the beginning of loading into the hold, but since the leakage time is extremely short, it is hardly a problem.

積付能率が発揮できる大なる効果がある。 As described above, according to the bulk material loading machine equipped with the dust-proof telescopic chute of the present invention, bulk materials can be continuously stowed in a ship hold or storage yard while changing the loading points one after another without leaking dust. Since this can be done, the loading capacity per hour can be greatly improved, which has the great effect of achieving extremely high loading efficiency.
