Embodiment Construction

[0021] Rock soil excavation device 1 comprises frame 2 and chain 3, and chain 3 is made up of chain piece 4 and pin shaft 5; Chain piece 4 comprises two kinds of structures of common chain piece 4-1 and the chain piece 4-2 that contains digging knife 6, The length of the chain piece 4-1 and the chain piece 4-2 is equal to or slightly less than twice the chain pitch, so that the granularity of rock and soil entering through the chain piece 4-1 and the chain piece 4-2 can be controlled within the design value.

[0022] The chain pieces 4 in the width direction of the chain 3 are densely distributed.

[0023] The chain pieces 4 densely distributed in the width direction are composed of several chain pieces 4-1 and several chain pieces 4-2.

[0024] The chain pieces 4 - 2 are arranged at intervals along the length direction of the chain 3 .

[0025] The chain 3 includes several standard segments, and on the horizontal projection of each standard segment, the knives 6 on the chain...

Abstract

The invention provides a chain for a rock-soil excavating device. The chain is characterized in that the rock-soil excavating device 1 comprises a rack 2 and a chain 3; the chain 3 consists of chain sheets 4 and pin shafts 5; each chain sheet 4 comprises two structures, namely, a common chain sheet part 4-1 and a chain sheet part 4-2 containing an excavating cutter 6; the length of each chain sheet part 4-1 and the length of each chain sheet part 4-2 are slightly smaller than twice the chain pitch, so that the granularity of rock-soil entering through the chain sheet parts 4-1 and the chain sheet parts 4-2 can be controlled within a design value; and the chain sheets 4 of the chain 3 in the width direction are closely distributed. The chain has the advantages that 1) the chain sheets and the pin shafts can be provided with the cutters for excavating the rock-soil, so that the efficiency is improved; 2) the chain can be bent specially; and 3) the granularity of the rock-soil entering the chain can be controlled within the design value, and embedded rock does not affect the driving of a driving chain wheel and the engagement of the chain, so that power transmission when the cutters of the chain excavate the rock-soil is facilitated.

Description

technical field [0001] The invention relates to a chain used for a rock and earth excavating device, which belongs to the technical field of engineering equipment. Background technique [0002] In the chain of existing rock and soil excavation equipment, rocks are easily embedded in the chain links, so that when the drive sprocket drives the chain cutter for rock and soil excavation, the drive sprocket and the chain cannot be meshed, or serious wear and tear will occur after meshing, which will affect the quality of the equipment. Normal use. Contents of the invention [0003] What the present invention proposes is the chain of rock and soil excavating device, and its purpose aims at overcoming the defective existing in the prior art, and its main advantage can be equipped with the cutting tool of digging rock and soil on chain plate and pin shaft, and chain can be bent in space, enters chain The particle size of the rock and soil in the joint can be controlled within t...
