Belt type conveying and discharging device for shield tunneling machine

Abstract

The invention discloses a belt type conveying and discharging device for a shield tunneling machine. The belt type conveying and discharging device comprises an upper conveying belt for conveying muck, a carrier roller set for supporting and adjusting the upper conveying belt, a discharging scraper for scraping off the muck on the upper conveying belt and a lower conveying belt for continuously conveying the muck; the lower conveying belt is arranged below the front side of the upper conveying belt; the carrier roller set is arranged on the inner side of the upper conveying belt and attached to the upper conveying belt, and a driving roller rotates to drive the upper conveying belt to move forwards in the direction of the lower conveying belt; and the transversely-inclined discharging scraper is arranged on the upper end face of the upper conveying belt where the lower conveying belt and the upper conveying belt are staggered, and muck conveyed on the upper conveying belt falls onto the lower conveying belt in the inclined direction of the discharging scraper. According to the belt type conveying and discharging device, the transversely-inclined discharging scraper is arranged, themuck on the upper conveying belt is pushed to the lower conveying belt in a centralized mode, conveying blockage of the upper conveying belt and the lower conveying belt cannot be caused, and the problem that under the condition that the space in the shield tunneling machine is limited, the muck transferring and discharging angle is insufficient is solved.

Description

technical field [0001] The invention relates to the technical field of shield machine conveying, in particular to a belt conveying and unloading device for a shield machine. Background technique [0002] Tunnel shield construction is a key project in many infrastructure fields such as transportation, hydropower and communication pipelines. In the construction of tunnel engineering, the harsh construction environment, narrow working space, and many restrictions on the installation conditions of construction equipment make it difficult to improve the efficiency of tunnel construction. These have become the main constraints for rapid construction. [0003] At present, the shield belt conveyor is generally arranged in the middle of the top of the shield machine. One of the conventional supporting slag discharge equipment is a slag truck, and the other is a continuous belt conveyor. The slag truck is connected to the outlet of the hopper installed on the head of the shield belt ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a belt conveying and unloading device for shield machines. This belt conveying and unloading device solves the problem of insufficient reloading and unloading angles of muck in the case of limited space in the shield machine. Satisfies the discharge angle of muck and reduces the risk of material blockage
