Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 There is shown a cutting insert 100 provided according to the invention, comprising a circular box-type insert face 1 , six spokes 2 and a central knife 3 . The spokes 2 are arranged on the front of the cutterhead panel 1, and the six spokes 2 are uniformly arranged radially from the center of the cutterhead panel 1 to the edge, thereby dividing the cutterhead panel 1 into six regions with equal areas. There are several pairs of cutting knives 4 symmetrically arranged in a figure-eight shape on both sides of each spoke 2, and a leading knife 5 is arranged between a part of the paired cutting knives 4, so that the cutting disc 100 can cut the soil whether it is forward or reverse. . The center knife 3 is fixed at the center of the cutterhead panel 1 by bolts, and is higher than the surface of the cutterhead panel 1, so that the center...

Abstract

The invention relates to a cutting blade disc of a muddy water balance push bench. The cutting blade disc comprises a circular box-type blade disc panel arranged at the front end of a cutting housing of the push bench, six spokes arranged at the front end of the blade disc panel, and a center knife arranged in the central position of the blade disc panel; the spokes are radially and uniformly arranged from the center of the blade disc panel to the edge, and divide the blade disc panel into six regions with equal areas; a plurality of pairs of splayed cutting blades are symmetrically arranged on the two sides of each spoke, and antecedence knifes are arranged among a part of paired cutting blades; two openable circular soil inlets are symmetrically formed in two of the six regions of the blade disc panel by using the center knife as a symmetric centre; rectangular openings are formed in the four other regions of the blade disc panel respectively, a plurality of pairs of scrapers are symmetrically and linearly arranged on the two sides of each rectangular opening, and narrow soil inlets are formed between every two scrapers. The cutting blade disc is suitable for both pure sand soil layers and complex soil layers, and can be widely used in various muddy water balance push benches.

Description

technical field [0001] The invention relates to a component of a pipe jacking machine, in particular to a cutting cutterhead of a mud-water balanced pipe jacking machine which is applicable to pure sandy soil layers and complex soil layers. Background technique [0002] With the development of social economy and the improvement of infrastructure, especially the acceleration of urbanization, the transmission pipeline projects of liquid and gaseous media passing through roads, rivers and buildings inside and outside cities are increasing day by day, and trenchless technology has been widely used. As a kind of non-excavation technology, the mud-water balanced pipe jacking machine has the advantages of adapting to wide soil layers, stable excavation surface, and small ground subsidence. Comprehensive pipeline, etc.) engineering, so it has been widely used. [0003] As the key component of the mud-water balance pipe jacking machine, the cutting cutter head directly affects the p...
