A grain screening funnel

Abstract

The invention discloses a grain screening funnel and relates to the technical field of grain processing equipment. The grain screening funnel comprises a funnel body, and a first discharging pipe is arranged at the bottom of the funnel body. A base plate is arranged inside the funnel body. First rotating shafts, second rotating shafts and third rotating shafts are symmetrically arranged above thebase plate in sequence. The first rotating shafts, the second rotating shafts and the third rotating shafts are all symmetrically provided with a plurality of stirring blades. Two screening plates aresymmetrically arranged inside the funnel body. The bottom ends of the two screening plates are both fixedly connected to the base plate. The screening plates are sequentially provided with first screening holes, second screening holes and third screening holes. Frist material slipping plates and second material slipping plates are obliquely arranged between the outer sides of the screening platesand the inner side of the funnel body. The bottom of each first material slipping plate is provided with a second discharging pipe. The bottom of each second material slipping plate is provided witha third discharging pipe. Due to the facts that the screening plates and the material slipping plates are arranged and the screening plates are provided with the multiple sets of the screening holes,production efficiency is improved and the grain screening funnel is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of grain processing equipment, in particular to a grain screening funnel. Background technique [0002] During the busy season, farmers generally need to screen the grain after harvesting it. The traditional screening method is mostly manual screening using a sieve. This screening method not only has low work efficiency, but also greatly increases the labor intensity of the operator. [0003] At present, the grain delivery funnel of the grain processing device on the market only plays the role of transporting grain, and other auxiliary devices need to be added for grain screening. However, adding these auxiliary devices not only increases the cost of equipment and use, but also takes up a lot of space, which brings many troubles to customers. Therefore, it is necessary to develop a kind of grain screening funnel to improve production efficiency and reduce use cost. Contents of the invention [0004] The ...
