Technical Field

The utility model relates to an excavator technical field, more specifically say and relate to an excavator ripper of free conversion of front shovel backhoe.

Background

The device has the functions of crushing and loosening. The excavator scarifier is also called a bucket hook, and the bulldozer scarifier is also called a tail hook, is generally single-tooth and also has two or three teeth, and has strong digging cutting force. The upper part of the integrally cast scarification tooth is provided with an ear hole which is respectively hinged with the bucket rod and the bucket cylinder, the front end of the tooth tip is provided with a tooth cap formed by hard alloy surfacing, and when a piston rod of the hydraulic cylinder extends out, the tooth tip is pushed to be forcibly inserted into and turn over soil. Used for excavating cracked rock, breaking frozen soil and excavating asphalt pavement. The device is suitable for crushing and splitting hard soil, secondary hard stone and weathered stone so as to facilitate excavation and loading operations by using an excavator bucket.

Excavator rippers are generally divided into two modes of operation, face and backhoe, as are the rock arms derived therefrom. Because of the particularity of the rock arm work, the backhoe rock arm excavator can adapt to most working conditions, so the rock arm excavator used in the market usually mainly uses the backhoe. When the backhoe rock arm excavator meets the working condition more suitable for a face shovel, only the backhoe can be constructed, and the construction efficiency is low or even the backhoe rock arm excavator cannot be constructed according to different working conditions; conversely, the same is true when the face rock arm excavator encounters conditions more suited to backhoes.

At present, partial excavators capable of freely converting forward shovels and back shovels exist in the market, and if the national intellectual property office is 7/30/2014, a utility model patent with the publication number of CN203741895U and the name of 'a forward and reverse dual-purpose excavator' is disclosed, and the utility model patent comprises a base, a movable arm oil cylinder, a movable arm, a bucket rod oil cylinder, a bucket rod, a bucket oil cylinder, a chain rod, a bucket auxiliary oil cylinder, a forward bucket tooth, a reverse bucket tooth and a bucket; the bucket comprises a base, a movable arm, a bucket rod oil cylinder, a bucket auxiliary oil cylinder and a bucket rod, wherein the movable arm is arranged on the base and controls swing rotation of the movable arm through stretching of a movable arm oil cylinder for connecting the base and the movable arm, the end part of the movable arm is hinged to the bucket rod, one end of the bucket rod oil cylinder is connected to the movable arm, the other end of the bucket rod oil cylinder is connected with the bucket rod and controls swing rotation of the bucket rod through stretching of the bucket rod oil cylinder, the end part of the bucket rod is hinged to a bucket, one end of the bucket oil cylinder is connected to the bucket rod, the other end of the bucket oil cylinder is hinged to one end of the bucket auxiliary oil cylinder and one end of a chain rod connected to the bucket rod. The utility model discloses possess the function of tradition just, back shovel excavator.

Although an excavator capable of being used for both front and back sides is available in the market at present, the excavator in the market at present is only suitable for the operations of excavation, pushing and filling, loading and unloading, hoisting and the like of materials such as earthwork and is not suitable for the crushing action on rocks. And the existing reversible excavator has more complex structure and higher cost.
