Soil blocking plate for channel tunneling machine

Abstract

The invention relates to a soil blocking plate for a channel tunneling machine. The soil blocking plate comprises a vehicle frame (1), wherein a transmission belt (2) is vertically connected to the lower part of the vehicle frame (1); first baffles (3) are respectively connected to two sides of the transmission belt (2); a shoveling plate (4) is hinged on the two first baffles (3) on the front side of the transmission belt (2); a position emptying groove (5) which is matched with the transmission belt (2) in a corresponding manner is formed in the shoveling plate (4); one second baffle (6) is respectively arranged at the position of each of two sides of the position emptying groove (5), of the shoveling plate (4); a push plate (7) is respectively hinged and fixed to the front end of each of the second blocking plates (6); an oil cylinder (8) hinged to the shoveling plate (4) is also respectively connected to the shoveling plate (4) on the outer side of each of the push plates (7). The soil blocking plate for the channel tunneling machine disclosed by the invention has the advantages that when soil is transported, the baffles are respectively arranged on two sides of the transporting path of the soil blocking plate, and the soil on the front side of the shoveling plate can be pushed to the middle of the shoveling plate by the push plates, so that in the soil transporting process, the soil cannot fell off to the outer sides of the tunneling machine.

Description

technical field [0001] The invention relates to a tunnel concealed excavation device, in particular to a soil retaining plate for a tunnel concealed excavator. Background technique [0002] A tunnel is a building built underground, underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing through large cities, it is called a tunnel. Those that pass underground are called urban tunnels. [0003] Tunnel excavation methods are divided into open-cut method and underground excavation method. The open-cut method is mostly used in shal...

Problems solved by technology

[0007] At present, when excavating tunnels, the excavated soil needs to be transported out through another transportation device, which requires a lot of manpower and material resources, which increases the cost. It is inconvenient to transport this part of the soil. Due to the limitation of the tunnel space, the operation is inconvenient. In order to solve the above shortcomings, the applicant has designed a tunnel excavator, and this application is applied to the tunnel excavator. mudguard
