Multi-degree-of-freedom follow-up sealing material receiving device under limited height

Abstract

The invention discloses a multi-degree-of-freedom follow-up sealing material receiving device under a limited height. The device mainly comprises a spherical crown-shaped blanking cover, a material receiving tank which is through up and down, and a sealing device between the spherical crown-shaped blanking cover and a tank body, and the like. The spherical crown-shaped blanking cover is hermetically connected with a transition chute at the upper part through a flange; the material receiving tank is fixed on a horizontal rotating shaft at the top of an arm support through a flange and a bolt; the material receiving tank, the arm support and the chute synchronously rotate and swing around the rotating shaft; and the space between the fixed spherical crown-shaped blanking cover and the material receiving tank which synchronously rotates and swings around the rotating shaft is sealed by an elastic sealing device. The chute of the arm support connected with the lower end of a material receiving device can be allowed to slightly swing within a limited height along with a ship body and can rotate along with a rotary table, and sealing between the material receiving device and an upper port is guaranteed all the time when the material receiving device swings and rotates.

Description

technical field [0001] The invention relates to the field of shipping machinery, in particular to a multi-degree-of-freedom follow-up sealing material receiving device at a limited height. Background technique [0002] At present, when loading a ship, it is necessary to transfer the bulk materials from the rear to the cabin through the ship loader. In order to make the material loading and unloading uniform, the ship loader is generally installed on the shore-based track to distribute the material evenly in the longitudinal direction. It is completed by the ship moving left and right and the belt conveyor on the arm of the ship loader rotating on the turntable. [0003] However, the ship floats on the water and is affected by the wind and waves, and the hull is easy to tilt and swing. However, the boom of the existing ship loader cannot swing slightly with the tilt of the hull, resulting in uneven loading, and the cabin space or overflow cannot be maximized. Contents of th...

[0003] However, the ship floats on the water and is affected by the wind and waves, and the hull is easy to tilt and swing. However, the boom of the existing ship loader cannot swing slightly with the tilt of the hull, resulting in uneven loading, and cannot maximize the use of cabin space or overflow.
