Good quality Excavator Undercarriage Wear - Bucket Link Rod – Pingtai

Aiming at the problem that it is difficult to protect the connecting rod of the excavator working device by using the traditional centralized lubrication scheme,According to the characteristics of connecting rod structure, the improved scheme of connecting rod centralized lubrication is put forward, in which the oil channel is processed inside the connecting rod instead of the traditional centralized lubricating oil pipe.The manufacturing process of internal oil passage of connecting rod is also given.The improvement scheme of connecting rod centralized lubrication has been compared with manual lubrication and traditional centralized lubrication. The results show that the improved scheme of connecting rod centralized lubrication completely solves the protection problem of traditional centralized lubrication of tubing and distributor.No exposed tubing, centralized lubrication, the overall layout is simple and beautiful;After 1 year of use in the construction site, there is no damage of connecting rod centralized lubrication parts. The lubrication system runs well and the efficiency is greatly improved.The operator hopes that the enthusiasm of the installation of centralized lubrication on the excavator has been greatly improved.For the connecting rod which has the condition of processing the internal oil passage, the improved centralized lubrication scheme of connecting rod has better popularization value.

The excavator bucket is connected with four connecting bucket link rod, which are composed of the upper connecting bucket link rod, the lower connecting rod, the rear connecting rod and the side side of the bucket.The front end of the connecting rod is hinged on the upper side of the bucket, the front end of the connecting rod is hinged on the lower side of the bucket, and the rear end of the connecting rod is respectively connected with the rear end of the connecting rod and the lower connecting rod;The lower connecting rod is arranged in the middle of a telescopic oil cylinder, telescopic oil cylinder telescopic end is connected with the middle of the connecting rod and drive the connecting rod swing, the connecting rod comprises a forearm and hind arm, the forearm and the upper side of the bucket hinged, the hind arm and the rear connecting rod hinged;Forearm and hind arm integrated structure.The new type of excavator connecting rod produced by our company has the advantages of exquisite structure, simple and convenient installation, high accuracy of structure, light weight, low cost and easy processing and manufacturing.

In order to solve the problems of excavator bucket’s action response and excavating force during operation, the kinematics and mechanics models of three different types of connecting bucket link rod mechanisms were established, and the excavating characteristic parameters such as the motion trajectory, response speed and maximum excavating force of the corresponding bucket were studied.The research results show that the buckets controlled by different linkage mechanisms have different excavation characteristics and working efficiency, but their excavation characteristics are consistent with the soil cutting characteristics.
