Embodiment Construction

[0012] A vibrating cleaning screen of the present invention comprises a cleaning screen frame 1, a shaking plate 2, a front shaft 3, an upper screen 4, a lower screen 5, an eccentric block 6, a driving shaft 7, a slide plate 8 and a tail screen 9. Shaking plate 2, upper sieve 4, lower sieve 5 and tail sieve 9 are installed on the cleaning screen frame 1, as shown in Figure 1. The shaking plate 2 is composed of three different corrugated plates. The corrugated plate 2c near the feeding entrance has a corrugated angle 10° larger than that of the middle 2b. The corrugated angle of the third plate 2a is 90°. When cleaning rice, the upper sieve 4 uses The upper woven sieve 4a, the structure of the rear scale sieve 4c, the lower sieve is the lower woven sieve 5a, and the tail sieve 9 is a scale sieve, as shown in Figure 2; when cleaning rapeseed, the upper sieve 4 adopts the upper punching sieve 4b, and the rear scale sieve 4c structure, the lower sieve is the lower punching sieve 5...

Abstract

A vibration-type screening sieve with high efficiency and productivity is composed of a sieve frame, a shaker board consisting of three corrugated boards with different corrugated angles, an upper sieve with longitudinally and segmentally combined structure, a middle sieve chosen from braided sieve and punched sieve, a lower sieve which is a scale sieve, a front axle, an active shaft, an eccentrical block and a slide plate.

Description

technical field [0001] The invention relates to a vibrating cleaning sieve for a harvesting machine, which is mainly used for cleaning and screening various crop extracts such as rice, wheat, rapeseed and soybean. Background technique [0002] At present, most harvesting machines adopt vibrating cleaning and screening structures, and the screen surfaces used mainly include scale screens, woven screens and punching screens. Fish scale sieve is currently the most used type of sieve surface in the cleaning system of combine harvesters. The separation ability is not strong. The braided sieve is mainly used for the cleaning of rice, the patent number is CN2643632, the structure is simple, the manufacture is convenient, the price is cheap, and the pushing effect on the prolapsed matter on the sieve surface is relatively weak. The perforated sieve is mainly used for seed screening. The patent number is CN2493013. It has a simple structure. The diameter of the sieve hole can be se...
