Abstract

The invention provides a bucket opening mechanism and a construction device, and relates to the technical field of electric shovel bucket opening. The bucket opening mechanism comprises a mechanical transmission system, wherein the mechanical transmission system comprises a motor, a steel wire rope, a first-stage lever, a second-stage lever, a bucket bolt, a bucket bottom plate and a bucket rod; the motor, the steel wire rope, the first-stage lever, the second-stage lever and the bucket bolt are sequentially connected; the first-stage lever is arranged on the bucket rod; the second-stage leveris arranged on the bucket bottom plate; and the second-stage lever is suitable for driving the bucket bolt to slide so as to open the bucket bottom plate when swinging. According to the technical scheme, the two-stage lever structure is arranged, so that the bucket opening strength is improved, and effective bucket opening is guaranteed; and meanwhile, the stress of the steel wire rope is effectively reduced through the second-stage lever, so that the service life of the steel wire rope can be prolonged.

Description

technical field [0001] The invention relates to the technical field of bucket opening of electric shovels, in particular to a bucket opening mechanism and construction equipment. Background technique [0002] The bucket opening system is an extremely important system in the operation device of the electric shovel. After the electric shovel completes the excavation operation, it needs to unload the materials in the bucket to the transport vehicle. At this time, it must pass through the bucket opening system. After the wire rope of the bucket-opening electric winch goes around the saddle and the guide pulley on the stick, it is connected to the labor-saving lever on the bottom plate of the bucket. It falls into the transport vehicle under the action of gravity to complete the unloading. After the unloading is completed, the bottom plate of the bucket is automatically closed under the action of gravity, and the bucket bolt is automatically locked. Therefore, the bucket opening...
