Embodiment Construction

[0015] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 and figure 2 As shown, this embodiment provides a corrugated vibrating screen, including a screen frame 2, a corrugated plate 3 for layering materials, an upper woven screen 4 for separating grains and sundries from materials, a tail screen 5 and a lower screen. The sieve 6, the corrugated plate 3, the upper woven sieve 4, and the tail sieve 5 are sequentially arranged in the sieve frame 2 from front to back, and the upper woven sieve 4 and the lower sieve 6 are arranged in the sieve frame 2 in turn Inside, the upper woven screen 4 adopts a corrugated upper woven screen. The upper woven screen 4 adopts a square hole screen. The distance between adjacent corrugations of the upper woven screen 4 is 8-25 cm, preferably 12 cm. The screen frame 2 is connected with an eccentric drive mechanism 1 for reciprocating the sc...

Abstract

The invention provides a corrugated vibrating screen which comprises a screen frame, a corrugated plate for material layering, an upper woven screen for separating seeds and sundries in materials, a tail screen and a lower screen. The corrugated plate, upper woven screen and the tail screen are sequentially arranged in the screen frame from front to back, the upper woven screen and the lower screen are vertically and sequentially arranged in the screen frame, and the upper woven screen is a corrugated upper woven screen. The problem that the vibrating screen cannot well adapt to sorting of different varieties of crops is solved by adopting the corrugated upper woven screen, accordingly the cleanness of wheat harvested by a wheat and rice dual-purpose harvester is ensured whether the wheat or the rice is harvested or not, meanwhile screen-surface material accumulation caused by high backward motion is avoided during rice harvesting, a part of non-separated materials is extruded, accordingly seed loss is effectively reduced, and production is facilitated.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a corrugated vibrating screen. Background technique [0002] The vibrating screen is one of the most important components of the harvester cleaning part, and its function is to separate the grain grains in the material from short stems, broken stems and leaves and other sundries. The vibrating screen determines the performance of the harvester: the cleanliness of the grain and the harvest loss. The harvester harvests the crops through the header, and transports the crops to the drum through the conveying trough, and the stalks are separated from the grains under the action of the drums. The stalks are removed from the machine, and small sundries such as grains will enter the vibrating screen for separation again. . [0003] Most of the harvesters are dual-purpose harvesters for wheat and rice, and there are many varieties of crops, so the adaptability of the harvester is required to be ...
