Description

Screening device

Technical Field

The utility model relates to a screening plant of material specifically says a scraper bowl that can sieve the material.

Background

In the prior art, mine materials or gravel and earth and stone materials are generally shoveled by using equipment such as an excavator and are stacked or loaded on a transport vehicle or other transport equipment in an indexing manner and transported to other places. Due to the complex components of the materials, especially the significant difference of the particle sizes of the materials, the materials can only be operated in a mixed state, which brings huge workload for the processing operation of the materials.

In order to solve the above problems, the chinese patent document discloses "a rotary screening bucket for sorting dregs" (CN208146370U), which specifically discloses the following technical contents: "rotary screening fill, including base 1, base 1 is equipped with support frame 2 and drive mounting bracket 3 along the length direction interval, support frame 2 and drive mounting bracket 3 and base integrated into one piece's overall structure. A plurality of crushing rake teeth 4 are arranged on the base 1 far away from one side of the driving installation frame 3 along the length direction of the base 1, and the crushing rake teeth 4 are arranged at intervals along the width direction of the base 1. The base 1 between the crushing rake teeth 4 and the support frame 2 is arranged in an inclined manner, and the inclined angle is 0-35 degrees; a reinforcing arm 13 is provided between the base 1 and the support frame 2. ", and" a rotary driving mechanism 5 is provided on the driving mounting frame 3, a roller frame 6 is provided between the supporting frame 2 and the rotary driving mechanism 5, and the roller frame 6 is connected with a driving part of the rotary driving mechanism 5.
