Description

Lift bucket with movable door and elevator adopting lift bucket

Technical Field

The utility model relates to a lifting machine technical field, concretely relates to take lift bucket of dodge gate and adopt lifting machine of this lift bucket.

Background

The lifter is a key part of the concrete mixing plant and is used for lifting aggregate such as sand and stone to a certain height from a low position along a track and putting the aggregate into the mixing main machine. The material storage hopper (lifting hopper) of the lifting machine has two structural forms, one is a tipping bucket unloading form, the other is a bottom opening door form, and the two structural forms are all adopted and are driven to lift by a motor, namely the lifting hopper is driven by a structure of driving a hoisting roller by the motor to lift and feed materials or descend and receive materials.

The dog-house (discharge opening) size of present lift-bucket is fixed, and its advantage is simple structure, and its weak point is that the dog-house can not adjust the activity, causes the lift-bucket to unload for a long time when meetting the grit material that water content is slightly bigger and mud content is slightly high easily, and the unloading is slow, and it is serious to be stained with the material in the fill, can't play broken hunch effect, leads to the emergence of the circumstances such as unloading even, causes equipment trouble, has seriously influenced holistic production efficiency. In the prior art, in order to solve the problem that materials are bonded on an elevator bucket in the operation process of the elevator, a commonly adopted method is to modify the structure of the elevator bucket, such as increasing the feeding angle or increasing the size of a feeding port; increasing the angle of the charge causes an increase in the lift stroke, resulting in lengthening of the track and thus a reduction in production efficiency. Moreover, the effect of improving the arch breaking effect is still not achieved, and the effect of eliminating the blocking fault is limited.

Chinese patent publication No. CN203697261U discloses an elevator bucket, which comprises a bucket body having an outlet, and a scraping unit for scraping material toward the outlet of the bucket body when discharging, wherein the scraping unit is disposed in the bucket body. This technical scheme strikes off the propelling movement through scraping the material unit to the material, can solve discharge opening putty problem to a certain extent, but the arrangement structure is complicated, and trouble such as jamming also can appear in the scraping unit that increases newly.

SUMMERY OF THE UTILITY MODEL
