[0008]

However, in the conventional lid structure and method of conveyance shown in FIGS. 4 and 5, the contents overflowing from the gap between the ladle and the lid are directly exposed to the outside of the ladle. Since it would be scattered, it could be dangerous to surrounding equipment or forklifts, which was dangerous.

Since it is difficult to finely adjust the speed of transportation by forklift, a shock acts on the ladle when the speed is inevitably changed or braked due to traffic conditions, and the contents overflow from the gap between the lid and the ladle. Occasionally, there were environmental and safety problems.

As a countermeasure against the above-mentioned problem, if a shield wall for protecting the driver is attached to the forklift, an obstacle such as limiting the driver's view will occur when performing work other than carrying the ladle. So it was difficult to realize.

Further, in the prior art shown in FIGS. 6 (A) to 6 (D), it is necessary to secure a gap a for relative movement between the cover and the ladle. As in the prior art shown, there is a problem of overflow, and there is a problem that tilting of the ladle becomes difficult if the gap a cannot be maintained due to adhered matter.

Therefore, an object of the present invention is to collect the contents without scattering to the outside even if a shock acts on the ladle at the time of unavoidable speed change / braking of the forklift to cause the contents to overflow from the gap between the lid and the ladle. The purpose of the present invention is to provide a safe lid that does not damage peripheral equipment or the forklift driver.

[0013]

The present invention provides a ladle lid for a ladle that is carried by a forklift and is detachably arranged at the upper end of the ladle and has a fire resistant lining on the inner surface thereof. A shielding wall is disposed on a side portion of the pot lid located on the driver's seat side, and a hot water pool portion is provided inside the shielding wall and a portion of the pot lid end portion facing the shielding wall. The structure of the ladle lid for ladle carried by the forklift is summarized.

[0014]

[Operation] The contents that overflow from the gap between the ladle and the lid are safely collected by the basin. Further, without taking measures on the forklift side, the driver and the ladle are shut off by the shielding wall to prevent the driver's safety and damage to the vehicle.

[0015]

FIG. 1 shows an embodiment of the present invention. In FIG. 1, a lid 9 is composed of a lid structure 11 lined with a refractory material 10, a refractory shield wall 13 and legs 14.
It is formed so that it can stand on its own.

The positional relationship between the ladle and the ladle 2 is shown. A is the front and rear pool 1
The inner dimensions of 5-1 and 15-2 are shown. B shows the dimension between the front and rear ends of the gutters of the ladle 2, and A is made smaller than B. C indicates the inner dimension in the height direction between the puddle portions 15-1 and 15-12. D indicates the dimension in the height direction of the protruding portion of the gutter of the ladle 2, and C is manufactured to be the same as or slightly larger than D.

FIG. 3 (A) shows a state in which the lid 9 is moved in the direction of the arrow and the ladle 2 is positioned between the pair of legs 14. Next, the lid 9 is lowered and moved slightly in the direction of the arrow to obtain the state of FIG. Further, while lowering the lid 9, the lid 9 is slightly moved (returned) in the direction opposite to the arrow, and the state shown in FIG.

In FIG. 3 (C), the tips of the spouts at the front and rear of the ladle 2 project above the hot water pool portions 15-1 and 15-2, respectively, so that the contents overflowing from the ladle water pool portion 15
It falls into -1, 15-2 and is collected.

[0021]

[Effects of the Invention] With the configuration as described above, the contents overflowing from the gap between the lid and the ladle are collected in the front and rear hot water pools without going out to the environment and safety. The above problem does not occur. Since the forklift side is protected by the shielding wall, it can be transported safely. And so on.

Further, in this embodiment, since the legs are arranged and the pot is of a self-supporting type, it is easy to grip the pot with a forklift.
