Three degrees of freedom vibrating screen drive mechanism

Abstract

The invention belongs to the field of agricultural machinery and discloses a driving mechanism for a three-degree-of-freedom vibration screen. A front angular swing arm, a limiting rod, an upper connection rod and a lower connection rod are sequentially hinged to a rocker on the left side, and the front angular swing arm is hinged to the three-degree-of-freedom vibration screen. A T-shaped swing arm and a lower connection rod are sequentially hinged to a rocker on the right side, and the T-shaped swing arm is hinged to the three-degree-of-freedom vibration screen, the upper connection rod and the limiting rod. Rear angular swing arms are hinged to the lower connection rods on the left and right sides respectively, and the rear angular swing arms on the left and right sides are hinged to the upper connection rods on the left and right sides respectively and hinged to the left and right sides of the three-degree-of-freedom vibration screen respectively. Ball cage assemblies are mounted between the left side of the three-degree-of-freedom vibration screen and the rear angular swing arm on the left side and between the right side of the three-degree-of-freedom vibration screen and the rear angular swing arm on the right side respectively. Left and right suspension rods are hinged to the left and right sides of the three-degree-of-freedom vibration screen respectively. The driving mechanism for the three-degree-of-freedom vibration screen has the advantages of simple, novel and reasonable structure, compact size, low manufacturing cost, high screening efficiency, high quality, reliability in use and wide application range.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a driving mechanism of a cleaning device on a harvesting and threshing machine tool. Background technique [0002] The vibrating screen on the traditional cleaning device can only complete the vibration in the vertical and vertical directions, and cannot realize the reciprocating swing of the vibrating screen as a whole. The grain distribution is uneven during the cleaning operation, and the effective use area of ​​the vibrating screen is small. The efficiency of cleaning and separation operation is low, and the separation quality is reduced. In order to solve the problems existing in the above-mentioned traditional technologies, a three-degree-of-freedom hybrid vibrating screen, or even a four-degree-of-freedom hybrid vibrating screen has been studied, but due to complex structure, high manufacturing cost, prone to failure, and large overall space occupation, etc. problem, promote...
