Abstract

The utility model relates to a combined harvester concave plate a vertical beam. An upper end and a lower end of the vertical beam, which are symmetrically arranged, are respectively welded with an arc-shaped cross beam to form a framework. Supporting beams, which are arranged in a horizontal-vertical crossed manner, are disposed in the framework. The framework is provided with an arc-shaped sieve plate, in which are orderly arranged ellipse-shaped or circle-shaped sieve holes. The combined harvester concave plate provided in the utility model has advantages of simple structure, reasonable design, easy costs, no broken grain particles by threshing, and abilities of preventing the economic losses caused by the broken grain particles by using the traditional concave plate threshing, and improving the efficacy.

Description

The combine notch board

Technical field

The utility model relates to a kind of combine notch board.

Background technology

At present, traditional notch board mainly is made up of horizontal reinforcement, waling and iron wire etc.Its threshing hole is by being vertical edge with the waling, being that horizontal edge interweaves and forms with the iron wire that passes waling that when its main weak point was work, the broken phenomenon of grain grain was more serious, has both reduced operating efficiency, has caused the certain economic loss again.

Summary of the invention

The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, is prone to the combine notch board of processing.

In order to achieve the above object; The technical scheme that the utility model adopts is: comprise vertical beam; The vertical beam upper/lower terminal position of symmetry is welded with the arcuation crossbeam respectively and forms framework; In framework, be provided with the brace summer that intersects anyhow, framework is provided with the arcuation sieve plate, on sieve plate, is provided with the ellipticity or the round sieve of proper alignment.

The utility model has the advantages that:

Simple in structure, reasonable in design, be prone to processing, with low cost, during threshing, the grain grain is not broken, has eliminated the economic loss of bringing owing to the broken grain of traditional notch board threshing, and has improved effect.

Description of drawings

Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment

Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.

Can know by Fig. 1-Fig. 2; The utility model comprises vertical beam 1, and the vertical beam 1 upper/lower terminal position of symmetry is welded with arcuation crossbeam 2 respectively and forms framework, in framework, is provided with the brace summer 3 that intersects anyhow; Framework is provided with arcuation sieve plate 5, on sieve plate 5, is provided with the ellipticity or the round sieve 6 of proper alignment.

Have connecting hole 4 at arcuation crossbeam 2 two-end parts.

The utility model is welded into the groined type framework with crossbeam and vertical beam; The iron plate that will have ellipticity or round sieve again is welded on the framework; The sieve plate of ellipticity or circular threshing sieve aperture is welded on the framework, and the threshing sieve aperture is the arcuation sieve plate that on iron plate, directly punches and form, because arcuation sieve plate and threshing sieve aperture are an integral body; So the sturdy and durable working life of processing with the iron plate of this band threshing sieve aperture of matrix plate is longer, solved the firm inadequately and variety of issue that causes of traditional matrix plate structure.The threshing sieve aperture intersects the sieve aperture of forming by two sections circular arcs and two parallel lines, and the mode that is uniformly distributed with arrangement is evenly distributed on the sieve plate.The utility model mainly is used for to crops threshings such as corn, soya beans, and during threshing, the grain grain is not broken, has eliminated the economic loss of bringing owing to the broken grain of traditional notch board threshing, and has improved effect.
