Problems solved by technology

The disadvantage of the existing technology is that the stick cylinder moves linearly, while the stick rotates. When the excavator completes the digging action of the stick, the required stroke of the stick cylinder is long. Due to the long stroke of the stick cylinder, the stick moves It takes a long time to affect the mining speed

Embodiment 1

[0014] Such as figure 1 As shown, the second shaft hole on the top of the bucket 2 is hinged to the front shaft hole of the excavator arm 1, and the power arm of the bucket is between the upper end of the bucket 2 and the hinge point. A stick oil cylinder 5 is provided for driving the stick 2 to rotate relative to the excavator arm 1, which is the prior art. There are rocker swing rod 3 and stick push rod 4. There are three working shaft holes on the rocker swing rod respectively. The three working shaft holes are arranged in a triangle shape. The first working shaft hole of rocker swing rod 3 passes through the The rocker bearing seat 6 at the front end of the swing arm 1 is hinged with the excavator power arm front, and the rocker bearing seat is located on the top surface, side or bottom surface of the excavator arm front end. In this embodiment, the hinge point is located on the top surface of the front part of the power arm of the excavator. The third working shaft hole...

Embodiment 2

[0017] The difference between the second embodiment and the first embodiment is that the swing arm of the rocker is arc-shaped, and the rest of the structure and working principle are the same as the first embodiment.

Abstract

The invention relates to a bucket rod rocker arm mechanism of an excavator. A second shaft hole of the upper portion of a bucket rod is hinged to a shaft hole of the front end of an excavator boom. The bucket rod rocker arm mechanism is provided with a bucket rod cylinder used for driving the bucket rod to rotate relative to the excavator boom. The bucket rod rocker arm mechanism is characterizedin that the bucket rod rocker arm mechanism is provided with a rocker arm swing rod, a bucket rod push rod and a rocker arm bearing block; the rocker arm swing rod is provided with three working shaftholes which are arranged in a triangular mode; the first working shaft hole of the rocker arm swing rod is hinged to a shaft hole of the rocker arm bearing block; the rocker arm bearing block is located at the front end of the excavator boom; the third working shaft hole of the rocker arm swing rod is hinged to a first shaft hole of the bucket rod push rod; a second shaft hole of the bucket rod push rod is hinged to a power arm of the bucket rod; a lug ring of a piston rod of the bucket rod cylinder is hinged to the second working shaft hole of the rocker arm swing rod; the bucket rod cylinder drives the bucket rod to rotate by driving the rocker arm swing rod and the bucket rod push rod. The bucket rod rocker arm mechanism can effectively shorten the stroke of the bucket rod cylinder andincrease excavation force and the excavation speed.

Description

technical field [0001] The invention relates to a stick rocker mechanism of an excavator. Background technique [0002] Excavators are indispensable construction machinery in modern society. With the development of society, people's technical requirements for excavators are getting higher and higher, especially the bucket excavation force of excavators is required to be larger and larger. In the prior art, the cylinder rod of the stick cylinder is directly hinged with the power arm of the stick, and the stick cylinder pushes the stick to rotate. The disadvantage of the existing technology is that the stick cylinder moves linearly, while the stick rotates. When the excavator completes the digging action of the stick, the required stroke of the stick cylinder is long. Due to the long stroke of the stick cylinder, the stick moves It takes a long time and affects the mining speed. Contents of the invention [0003] The object of the present invention is to provide a stick ro...
