Vibrating sieve device for combine harvester

Abstract

The invention discloses a vibrating sieve device of a combine harvester. The vibrating sieve device includes a support frame, a screening net, a vibrating device, a discharging device and a feeding hopper; the screening net is fixed through a metal frame on the surface, an annular groove is formed in the side face of the metal frame, and the screening net is fixed inside the metal frame through the groove; the vibrating device comprises a vibrating motor and a hydraulic rod, the vibrating motor is arranged at the bottom end of the metal frame, hinged bases are arranged at corners of the bottomend of the metal frame, and the metal frame is connected together with the hydraulic rod through the hinged bases in a hinged mode; the discharging device comprises a first discharging plate and a second discharging plate, the first discharging plate is connected with one end of a screening chamber, and the second discharging plate is connected with one end of a discharging chamber. According tothe vibrating sieve device of the combine harvester, quick screening of materials is achieved through dual vibration, the materials after screening can be quickly classified and discharged, meanwhilereplacement of the screening net is convenient, the screening effect is good, and the vibrating sieve device is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to a vibrating screen device of a combine harvester. Background technique [0002] Grain combine harvester, referred to as combine harvester, is a combined machine for harvesting crops. It was called Combine in the early 1950s. Harvesting machinery that directly obtains grain from the field. Before the combine harvester appeared, threshers and mechanical harvesters greatly improved agricultural productivity in the 19th century. This made it possible to harvest more grain with fewer workers than before. But an invention in the late 1800s took this efficiency even further. Combine harvesters combine harvesting and thresher in one unit, enabling farmers to harvest and thresh in a single operation. Thereby saving manpower and material resources and greatly reducing the burden on farmers; [0003] The application number is 201420654506.X, and the patent name is a combine harvester...

AI Technical Summary

Problems solved by technology

[0004] However, when the device is used for vibration screening, the replacement of the screen cannot be realized, and it is inconvenient to discharge the screened material.
