Problems solved by technology

[0002] Existing excavator rock arms are mostly box-type like traditional excavator arms, and the production hours are long. If mass production is not possible, the production cost will be greatly increased, and the weight of the small arm is difficult to meet the needs of more working conditions. The filler cannot lift the small arm to the weight required for work, and most of the existing rock arms of excavators use traditional scarifiers, which have shallow excavation depth, complex structure, short service life, easy failure, and high maintenance costs; The oil cylinder seems to make the ripper flexible, but actually it only plays a supporting role

Embodiment 1

[0014] Embodiment 1: as figure 1 As shown, this embodiment provides a new type of integrated small arm rock-breaking tool, including a large arm 1, a small arm 2, a gear seat 3, and a middle arm oil cylinder 4. The large arm 1 and the small arm 2 are hinged, and the middle arm The cylinder end of the arm cylinder 4 is hinged with the boom 1, the other end of the middle arm cylinder 4 is hinged with the forearm 2, and the hinge point of the middle arm cylinder 4 with the forearm 2 is higher than that of the boom 1 and the forearm. 2 articulated hinge points, the lower part of the forearm 2 is crescent-shaped, the tooth seat 3 is set at the lower end of the forearm 2, the stick cylinder is omitted, and the combination structure of the forearm and ripper is adopted, so that the forearm It becomes an integral excavation body, without the obstruction of various structural parts of traditional rippers, so that the digging depth is deeper and the maintenance cost is greatly reduced. ...

Abstract

The invention discloses a new type integrated small arm rock breaking tool, which includes a large arm, a small arm, a tooth seat and a middle arm oil cylinder. The structure makes the forearm an integral excavating body without the obstruction of various structural parts of traditional rippers, so that the digging depth is deeper and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a novel integrated small-arm rock-breaking tool. Background technique [0002] Existing excavator rock arms are mostly box-type like traditional excavator arms, and the production hours are long. If mass production is not possible, the production cost will be greatly increased, and the weight of the small arm is difficult to meet the needs of more working conditions. The filler cannot lift the small arm to the weight required for work, and most of the existing rock arms of excavators use traditional scarifiers, which have shallow excavation depth, complex structure, short service life, easy failure, and high maintenance costs; The oil cylinder seems to make the ripper flexible, but actually it only plays a supporting role. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of in...
