Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of mine backhoe loader digging mechanism.
In order to realize foregoing invention purpose, the technical scheme that this utility model employing is as described below:
A kind of mine backhoe loader digging mechanism, including large arm, big arm cylinder, forearm, oil cylinder of small arm, bucket, bucket cylinder and big arm seat, one end with big arm seat respectively, one end of described large arm and big arm cylinder is flexibly connected, the other end of big arm cylinder is movably connected with large arm, described forearm one end is movably connected with bucket, the forearm other end is movably connected with the other end of large arm, oil cylinder of small arm one end is movably connected in large arm, the oil cylinder of small arm other end is movably connected with the forearm other end, described bucket cylinder one end is movably connected with forearm, the bucket cylinder other end is flexibly connected with bucket.
Preferably, it is movably hinged by chain frame between forearm one end and bucket.
Preferably, described chain frame includes chain frame A and chain frame B, and chain frame A is hinged with one end of chain frame B, and the other end of chain frame A is movably connected with bucket, and the other end of chain frame B is articulated with forearm one end, and the other end of described bucket cylinder is hinged with one end of chain frame A, chain frame B respectively.
Preferably; hinged by linking arm between forearm one end and bucket; described linking arm includes bracing frame, rotating shaft, fixed arm, lever arm and hydraulic cylinder; one end of bracing frame is hinged with forearm one end; connect at the bracing frame other end and have two fixed arms; and be arranged in parallel about two fixed arms; respectively by rotating shaft pivot joint one lever arm on two fixed arms; offer installation notch on the side of lever arm free end, the upper surface of lever arm free end offers the through hole running through described installation notch；Two lever arms are respectively connected with hydraulic cylinder.
Preferably, being arranged with sealing shroud on the outer surface of rotating shaft, sealing shroud, between lever arm and fixed arm, is respectively equipped with end cover at the both ends of rotating shaft.
Owing to using technique scheme, this utility model has a following superiority:
1, this utility model makes bucket obtain in space stretching, extension working range by increasing chain frame between forearm and bucket, improves the motility in bucket stretching process and stability, and certainly, the setting of chain frame also improves use safety.
2, after this utility model and bucket being installed, due between lever arm and fixed arm for pivot joint, therefore bucket can be driven to move in the horizontal direction by hydraulic cylinder, carry out taking off and be taken as industry, improve working range and work quality；By arranging sealing shroud and end cover in rotating shaft, effectively organize lubrication butter fat liquid stream to go out so that it is the most wear-resisting, substantially prolongs service life, decrease the incidence rate of security incident.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in further detail by embodiment.
Embodiment one, as shown in Figure 1, a kind of mine backhoe loader digging mechanism, including large arm 7, big arm cylinder 8, forearm 5, oil cylinder of small arm 6, bucket 1, bucket cylinder 4 and big arm seat 9, one end with big arm seat 9 respectively, one end of described large arm 7 and big arm cylinder 8 is flexibly connected, the other end of big arm cylinder 8 is movably connected with large arm 7, it is movably hinged by chain frame between forearm 5 one end and bucket 1, described chain frame includes chain frame A2 and chain frame B3, chain frame A2 is hinged with one end of chain frame B3, the other end of chain frame A2 is movably connected with bucket 1, the other end of chain frame B3 is articulated with forearm 5 one end, the other end of described bucket cylinder 4 respectively with chain frame A2, one end of chain frame B3 is hinged；Forearm 5 other end is movably connected with the other end of large arm 7; oil cylinder of small arm 6 one end is movably connected in large arm 7; oil cylinder of small arm 6 other end is movably connected with forearm 5 other end, and described bucket cylinder 4 one end is movably connected with forearm 5, and bucket cylinder 4 other end is flexibly connected with bucket 1.
In this embodiment, by arranging chain frame between bucket and forearm so that bucket stretches working range and obtains in space, improve the motility in bucket stretching process and stability, during it addition, junction point between bucket and chain frame is impaired, the setting of chain frame also improves use safety.
Embodiment two, such as Fig. 2, shown in 3, it is in place of the different structure of this embodiment and embodiment one: hinged by linking arm between forearm 5 one end and bucket 1, described linking arm includes bracing frame 10, rotating shaft 12, fixed arm 11, lever arm 13 and hydraulic cylinder, one end of bracing frame 10 is hinged with forearm 5 one end, connect at bracing frame 10 other end and have two fixed arms 11, and two fixed arms about 11 be arranged in parallel, respectively by rotating shaft 12 pivot joint one lever arm 13 on two fixed arms 11, the side of lever arm free end offers installation notch 15, the upper surface of lever arm free end offers the through hole 14 running through described installation notch；Two lever arms 13 are respectively connected with hydraulic cylinder.
