Technical Field

Background

In geotechnical engineering, there is often a process of transporting materials from one platform device to another platform device, for example, when a shield machine excavates a tunnel, due to the longer length of the shield machine, the excavated soil and stones need to be transported to the rear of the shield machine by using a conveyer belt, and due to the fact that a large amount of soil and stones exist in the tunnel, the soil and stones are mixed together, and most of existing transporting devices transport the soil and stones together.

In another embodiment, the openings of the v-shaped mesh 303 are directed to the right. Under the effect of buffering inclined plate 302 inclined plane, when earth and stone slide from the left end of buffering inclined plate 302 to the right end, the stone is intercepted by v-shaped grid 303, and under the effect of v-shaped grid 303, the stone moves to the front and back both ends of v-shaped grid 303, and the middle part of v-shaped grid 303 is blocked less by the stone, still can pass through earth, prevents that the grid hole on the v-shaped grid 303 from being blocked completely, appears earth and passes through less problem.

Soil falls to the bottom of the muck truck 200 first, stones fall into the muck truck 200 again, and when stones fall into the muck truck 200, the stones are directly contacted with the soil, so that the stones are prevented from being directly contacted with the bottom of the muck truck 200, and the impact of the stones on the bottom of the muck truck 200 is reduced. And the stones are released after reaching a certain amount, so that the stones are prevented from sliding down when the buffer effect is not achieved, and the stones are prevented from causing large impact on the muck truck 200.

When the muck truck 200 is transported to the rock and soil, the buffer inclined plate 302 is inclined due to the buffer mechanism 300, as shown in fig. 9, stones which directly slide from the buffer inclined plate 302 do not come to the rear side of the muck truck 200, and only a part of stones roll to the rear side of the muck truck 200, so the muck truck 200 is not filled up, and the drop of soil and stones caused by vibration of the muck truck 200 during transportation is prevented.
