Embodiment Construction

[0015] Such as figure 1 As shown, a bucket opening mechanism of a mining excavator bucket includes: a bucket hoist 1, a guide pulley 2 fixed on the boom 7 through a saddle 7-1, and a steel wire rope connected to the bucket hoist 1 3, and the fixed pulley 5 fixed on the side of the bucket 8, the side of the bucket 8, behind the fixed pulley 5, is equipped with a rocker lever 4, and the wire rope 3 goes around the fixed pulley 5 and the The long arm end of the rocker lever 4 is connected by a wedge sleeve 6, and the short arm end of the rocker lever 4 is connected with the bucket 9 by a wire rope.

[0016] Such as figure 2 , 3 As shown, the arm length ratio (ie lever ratio) of the long arm 4-1 and the short arm 4-2 of the rocker lever 4 is 2.5-3.

[0017] The rocking arm axle 4-3 of described rocking arm lever 4 is installed on the rocking arm frame 4-4, and rocking arm frame 4-4 is fixed on the side of bucket bar 8.

[0018] Such as Figure 4 As shown, the pulley shaft 5-...

Abstract

The invention provides a bucket-opening mechanism of a mining excavator bucket and relates to the bucket of the mining excavator. The bucket-opening mechanism is used for solving the problem of high failure rate of the bucket-opening winding motor of the existing bucket-opening mechanism of the excavator. The bucket-opening mechanism comprises a bucket-opening winding machine, a guiding pulley mounted on an erector arm and fixed through a saddle, a wire rope connected to the bucket-opening winding machine and a fixed pulley mounted on a side wall of a bucket rod, wherein a rocker lever is mounted on the side wall of the bucket rod and is located behind the fixed pulley; the wire rope is connected to the long arm end of the rocker lever through a wedge sleeve in the form of passing by the fixed pulley; and the short arm end of the rocker lever is connected to the bucket through the wire rope. The bucket-opening mechanism is used for a surface mining excavator and has the advantages of low failure rate of bucket-opening winding motor, low production cost of products, convenience in on-site replacement, labor-saving and time-saving operation, high efficiency, safe and reliable use, and the like.

Description

technical field [0001] The invention relates to a mining excavator, in particular to a bucket of the mining excavator. Background technique [0002] At present, the excavator bucket opening mechanism used in open-pit mines includes: bucket hoist, guide pulley fixed on the boom through the saddle, steel wire rope connected with the bucket hoist, and fixed pulley installed on the side of the stick. The wire rope passes through the guide pulley from the open bucket winch, and then goes around the fixed pulley to connect with the bucket. The fixed pulley fixed on the stick only plays a guiding role, so the load transmitted to the hoist motor is large, which is easy to burn out and has a high failure rate. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, provide a bucket opening mechanism of a mining excavator bucket, and solve the problem of high failure rate of the bucket opening winch motor of the exi...
