Embodiment Construction

[0008] The gear box 1 is connected to the arm 7 of the excavator; the outer side of the gear box 1 is fixed with a hydraulic motor 6, and a worm gear mechanism composed of a worm wheel 2 and a worm 5 is arranged inside the box, and the access end of the worm 5 is connected to the hydraulic On the power output end of the motor 6, the power output end of the worm gear 2 stretches out of the gear box body 1 through the connecting shaft 3 and is connected with the grab bucket 4. When the grab bucket 4 needs to be rotated, as long as the hydraulic motor 6 is started to rotate and the motion transmission between the worm gear and worm mechanism decelerates and the 90° intersection angle, the grab bucket 4 can rotate freely at any angle to meet the needs of the excavator's excavation environment.

Abstract

The invention relates to a rotary clamp excavator, in particular to a movement manner of a clamp bucket of the clamp excavator, belonging to the field of design and manufacturing of engineering machinery. The rotary clamp excavator comprises a gearbox, a hydraulic motor, a worm gear mechanism, a connecting shaft, a clamp bucket and an excavator arm, wherein the excavator arm is connected with the gearbox; the hydraulic motor is arranged outside the gearbox; the worm gear mechanism is arranged in the gearbox; an input end of the worm is connected with an output end of the hydraulic motor; and an output end of the worm is connected with the clamp bucket by the connecting shaft. The rotary clamp excavator uses the hydraulic motor to input power and uses the worm to drive the gear to rotate so as to drive the clamp bucket by the gear to rotate, thus, the free rotation function of the clamp bucket is increased. The rotary clamp excavator disclosed by the invention has notable advantages of simple structure, reasonable mechanism and flexible rotation of the clamp bucket, and is time- and labor-saving and energy-saving.

Description

technical field [0001] The invention relates to an excavator, in particular to a movement mode of an excavator grab, and belongs to the field of construction machinery manufacturing. Background technique [0002] Excavators widely used in construction projects currently have only one degree of freedom of movement between the grab bucket and the grab arm, that is, the degree of freedom for the grab bucket to rotate around the movable hinge axis between the grab bucket and the grab arm, so the grab bucket Can only move back and forth. Due to the single action of the grab, the excavating flexibility and operating space of the excavator are greatly limited. For example, when excavating the soil under or next to obstacles, the excavator can only move its position frequently so that the grab can It can satisfy the mining environment where it is located. Such an operation is labor-intensive, time-consuming and wastes energy and power. Sometimes it is impossible to carry out excav...
