Abstract
The utility model relates to a novel excavating mechanism of a backhoe loader. According to the novel excavating mechanism of the backhoe loader, a joint arm (5) and a joint arm oil cylinder (6) are arranged between a small arm (3) and a big arm (7), and the joint arm (5) is hinged to the small arm (3), the big arm (7), a small arm oil cylinder (4) and the joint arm oil cylinder (6) through hinge pins. Through control over stretching and retracting of an excavating bucket oil cylinder (2), the small arm oil cylinder (4), the joint arm oil cylinder (6) and a big arm oil cylinder (8), the work position of an excavating bucket (1) can be changed, and the excavating bucket can work in higher, further and deeper positions. In this way, the excavation work range of the excavating bucket can be greatly widened without frequently moving the backhoe loader, the movement frequency of the backhoe loader is reduced, the work efficiency of the backhoe loader is improved, and the novel excavating mechanism is suitable for crawler type backhoe loaders, tyre type backhoe loaders and rail wheel type backhoe loaders.
Description
Technical field
The utility model relates to the excacation mechanism of mine backhoe loader, particularly a kind of excacation mechanism that can change mine backhoe loader working range.
Background technology
The excacation mechanism of tradition loader-digger is mainly comprised of large arm, forearm, bucket and oil cylinder etc., although this traditional loader-digger has the features such as digging efficiency is higher, operation is simple, applicability is stronger.But the working range of traditional loader-digger is less, same loader-digger cannot meet larger excavation depth, excavate height and excavate the requirements such as width, restricted the performance of loader-digger performance.Excacation identity distance from loader-digger away from or darker in the situation that, mobile loader-digger continually, could obtain more satisfactory operating position, therefore just increased non-excavating and taken off the working time of getting, reduce the operating efficiency of loader-digger.
Summary of the invention
The technical problem that the utility model solves is: the loader-digger excacation that a kind of working range is wide, operating efficiency is high, applicability is strong, simple in structure mechanism is provided.
The technical scheme of the utility model technical solution problem is: the excacation mechanism of described loader-digger comprises bucket 1, bucket cylinder 2, forearm 3, oil cylinder of small arm 4, joint arm 5, joint arm oil cylinder 6, large arm 7, big arm cylinder 8, large arm seat 9 parts such as grade, described bucket 1 is hinged by bearing pin with bucket cylinder 2A end and forearm 3C end respectively, described bucket cylinder 2B end is hinged by bearing pin with forearm 3, described oil cylinder of small arm 4E end is hinged by bearing pin with forearm 3, described joint arm 5 is held with forearm 3D respectively, oil cylinder of small arm 4F end, joint arm oil cylinder 6G end, large arm 7K end is hinged by bearing pin, described joint arm oil cylinder 6H end is hinged by bearing pin with large arm 7, described big arm cylinder 8 two ends are hinged by bearing pin with large arm 7 and large arm seat 9 respectively, described large arm 7L end is hinged by bearing pin with large arm seat 9.
The utility model is provided with joint arm 5 and joint arm oil cylinder 6 between forearm 3 and large arm 7, and described joint arm 5 is provided with four articulated position, hinged with forearm 3, large arm 7, oil cylinder of small arm 4, joint arm oil cylinder 6 respectively; The installation site of appropriate design oil cylinder of small arm 4, joint arm oil cylinder 6 and big arm cylinder 8, by the flexible mutual alignment that can control between forearm 3, joint arm 5, large arm 7 of each oil cylinder, thereby change the operating position of bucket, can make bucket in higher, farther, darker position work, significantly expanded the excacation scope of loader-digger, reduce loader-digger travel frequency, improved the operating efficiency of loader-digger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1-bucket, 2-bucket cylinder, 3-forearm, 4-oil cylinder of small arm, 5-joint arm, 6-joint arm oil cylinder, the large arm of 7-, 8-big arm cylinder, the large arm seat of 9-.
The specific embodiment
As shown in Figure 1, the excacation mechanism of described loader-digger comprises bucket 1, bucket cylinder 2, forearm 3, oil cylinder of small arm 4, joint arm 5, joint arm oil cylinder 6, large arm 7, big arm cylinder 8, large arm seat 9 parts such as grade, described bucket 1 is hinged by bearing pin with bucket cylinder 2A end and forearm 3C end respectively, described bucket cylinder 2B end is hinged by bearing pin with forearm 3, described oil cylinder of small arm 4E end is hinged by bearing pin with forearm 3, described joint arm 5 is held with forearm 3D respectively, oil cylinder of small arm 4F end, joint arm oil cylinder 6G end, large arm 7K end is hinged by bearing pin, described joint arm oil cylinder 6H end is hinged by bearing pin with large arm 7, described big arm cylinder 8 two ends are hinged by bearing pin with large arm 7 and large arm seat 9 respectively, described large arm 7L end is hinged by bearing pin with large arm seat 9.
Described joint arm 5 is arranged between forearm 3 and large arm 7, hinged with forearm 3, large arm 7, oil cylinder of small arm 4, joint arm oil cylinder 6 respectively; During work, by flexible drive bucket elevating movement Shang Xia 1 of bucket cylinder 2, flexible drive forearm 3 and bucket 1 by oil cylinder of small arm 4 move up and down around joint arm 5, telescopic band movable joint arm 5, forearm 3 and bucket 1 by joint arm oil cylinder 6 move up and down around large arm 7, and the large arm 7 of flexible drive, joint arm 5, forearm 3 and the bucket 1 by big arm cylinder 8 rotates around large arm seat 9.
Described oil cylinder of small arm 4 and joint arm oil cylinder 6 extend to the longest, and big arm cylinder 8 is contracted to the most in short-term, control bucket cylinder 2 and can make bucket 1 peak, and lift the elevation angle and can reach 90 °; Described joint arm oil cylinder 6 is contracted to the shortest, and big arm cylinder 8 extends to when the longest, controls bucket cylinder 2 and oil cylinder of small arm 4 and can make bucket 1 reach deepest point; Described big arm cylinder 8 extends to the longest, controls joint arm oil cylinder 6, bucket cylinder 2 and oil cylinder of small arm 4 and can make bucket 1 reach solstics; By controlling the flexible of each oil cylinder, can make bucket 1 in different operating positions, can make bucket 1 in higher, farther, darker position work, significantly expanded the excacation scope of loader-digger, reduced loader-digger travel frequency, improved the operating efficiency of loader-digger, be suitable for the loader-diggers such as crawler type, rubber-tyred or rail wheel type and use.
The present embodiment is joint arm oil cylinder 6, big arm cylinder 8 to be separately positioned on to below and the top of large arm 7, also joint arm oil cylinder 6, big arm cylinder 8 can be separately positioned on to the above and below of large arm 7.
