Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packet chain continuous unloader.

Conventionally, continuous unloaders have been known in the form of continuous unloaders, but those intended for general ocean-going ships in particular insert the excavation part through a narrow hatch opening.
It is required that the excavation part can reach every corner inside the hatch. An example of omniscience that satisfies this is shown in Figure @1'. In this example,
When collecting the burr, it is excavated and collected at the lowest horizontal part of the packet chain, as shown in FIG. 2(a).

Now, in Figure 2 (al), the cross-sectional area of the hatched part is A (m'') (hereinafter referred to as the sampling cross-sectional area), the traverse speed of the packet is V (m/k), and the specific gravity of the material to be handled is If ρ(t/+c''), the collection capacity Q is expressed by the following equation.

Q==60aA*VT*ρ(t/h) On the other hand, the amount of collected one packet is 1m')l Packet installation pitch P (m,), packet chain speed V, (m/m)
Then, Q=V・(60Va)・ρ/P(t/h) f21
Then, formula (3) is obtained from the formula (11, +21).

Vt/Vm=”/A・(V/P)
(31 That is, it can be seen that the ratio of each velocity VT to vl is inversely proportional to the sampling cross-sectional area A.

Further, this ratio indicates the slope of the trajectory of the packet cutting edge during excavation, and the smaller the slope, the less resistance during traversing, and the smaller the lateral movement force. On the other hand, as is clear from equation (1), if you want to increase the sampling capacity Q, it is necessary to increase the sampling cross-sectional area M or increase the traversal speed 7, but from the above point of view, the sampling cross-sectional area A It can be said that it is better to make it larger. However, in the case of the conventional type, in order to increase the sampling cross-sectional area, it is necessary to increase the width B of the horizontal portion, which increases the size of the excavated portion. On the other hand, small and medium-sized boats with narrow spaces have drawbacks such as poor maneuverability and difficulty in handling.

In addition, in the conventional method, when sampling is carried out continuously in a horizontal direction and turned back at the end of the hatch, it is necessary to move the excavation part by the sampling width B as shown in Figure N2 (at), and during this time sampling cannot be carried out. Therefore, there is also the disadvantage that as the sampling width B increases, the cargo handling efficiency decreases accordingly.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks, and to provide a highly efficient continuous unloader that has a small excavation section and can be used on relatively small ships despite its large capacity.

The cost advantage of the present invention is that by tilting the excavation section of the continuous unloader, the width of the excavation section can be reduced to obtain the same sampling cross-sectional area as the conventional type, and the sampling section can be made smaller in order to sample the hatch corners. It is configured to be supported by expansion and contraction 1ItlII, and the excavated part can be deformed protrudingly without changing the total length of the chain.

An embodiment of the present invention is shown below in FIGS. 2(b) and 3.

The explanation will be given again with reference to FIG. jff4 and FIG. 5.

FIG. 3 shows an overall view of a continuous unloader according to an embodiment of the present invention. At the bottom of the packet chain type elevator 1 supported from the unloader body, sprockets 2 and 3 are arranged vertically so that the packet chain 4 has an appropriate slope, and the two are connected by a connecting rod 5.
Try to maintain a constant distance. The sprocket 3 consists of a telescopic cylinder 7 which is rotatably attached to a part of the frame 1 of the packet chain elevator with a pin 6, and a telescopic cylinder 7 which is rotatably attached to a pin 8 provided in another frame. It is supported by two cylinders (cylinder 9). On the other hand, the sprocket 2 is supported by a telescoping cylinder lO which is rotatably attached with a pin 8.

Since this embodiment is configured as described above, Section 25A(b)
As shown in the figure, if the sampling width B is the same as that of the conventional type, it is possible to make the sampling cross section larger than that of the conventional type.) Therefore, as is clear from equation (1), Furthermore, for the same sampling capacity, this embodiment has the advantage that the traversing speed Vi of the excavation part can be reduced, and therefore less power is required for traversing.

In addition, if the same sampling capacity and traverse speed as the conventional type are used, it is possible to reduce the sampling width B, and the entire excavation section can be made smaller, making it possible to handle cargo even for smaller ships. There are some advantages.

The above has described the advantages of having a slope in the excavation part, but the conditions that allow extraction of the hatch corner, which is required as a function of a continuous unloader for general ships, are different from those previously described. As shown in Figure 1, there are hinge points ν, 13 installed so that the lower part of the excavation part forms a parallelogram, and 9 cylinders 13 installed on the diagonal of the parallelogram. By expanding and contracting, the excavated part can be deformed protrudingly without changing the total length of the packet chain.

In this embodiment, three cylinders 7.9.10 are connected to the packet chain 4 between pins 6 and 8 as shown in Figure J1!5.
By controlling the expansion and contraction so that the length L of
It is possible to deform the excavated portion in a protruding manner as shown in Figure 5. At this time, the rotation center 14 of sprockets 2 and 3. Since the distance between b remains unchanged, if the cylinder 7 is extended on its extension line, the cylinder lO can be shortened by that amount on the extension line. Therefore, the operation is simple.As mentioned above, according to the present invention, the two sprockets of the excavation part are supported by the telescopic drive device, and the excavation part is sloped.
The slope is used to control the expansion and contraction of the expansion and contraction drive device.
Since the length of the packet chain can be changed arbitrarily without changing the length of the packet chain, it can maintain the same capacity as the conventional model without losing its function as a continuous unloader, which allows the excavation part to protrude and collect material up to the hatch corners of the ship. Compared to things, (
It has become possible to narrow the width of the 111t Fjll Ml, making it possible to launch a 1lIII from a much smaller ship.
(2) Less excavation resistance] The packet chain drive device can be made smaller, the distance traveled at the turning point of +31 II cutting can be reduced, and cargo handling efficiency can be improved.
