Description
Technical field
The utility model relates to grain threshing machinery, relates in particular to a kind of screen device.
Background technology
Screen device is the most important parts that are used in the grain header, it has the effect that the rice bar with rice separates with paddy, generally be provided with rotating threshing broach in the centre of screen device, it is rotating from the outlet that enters the mouth to drive rice, but the cross section of existing screen device is semicircle, top cover and screen device by the screen device top form the enclosure space that a cross section is a circle, adopt this structure rice only below screen device on just can reach the effect that the rice bar separates with paddy, so often cause from the rice bar that comes out and also have residual paddy, cause the waste of paddy, and the efficient of thrashing is low.
The utility model content
The purpose of this utility model is to improve the deficiencies in the prior art and provides a kind of simple in structure, and is easy to use, the efficient of thrashing height, screen device with low cost.
The purpose of this utility model is achieved by adopting following technical proposals:
A kind of screen device, comprise rack-mounted cylinder frame and intraskeletal grass guide board is installed, one side of described skeleton is provided with import, opposite side is provided with outlet, described skeleton is wrapped with screen cloth, and described screen cloth comprises upper screen cloth and lower screen cloth, and described upper screen cloth and described lower screen cloth both sides are connected to form an integral body, the upside of described upper screen cloth is equipped with the top cover that guiding paddy falls, and the two ends of described top cover are installed on the skeleton.
In the utility model, the cross section of described top cover is semicircle.
In the utility model, the inboard position near outlet of described skeleton is equipped with blade.
In the utility model, the inboard midline position of described top cover is provided with the guide plate that cross section is a del.
Adopt such scheme, the utility model comprises upper screen cloth and lower screen cloth, on, lower screen cloth forms a full circle, rice is in the process of rotation like this, no matter up or the below can reach the effect of threshing, and above upper screen cloth, be provided with the top cover that play the guiding role, top cover will guide to from the paddy that upper screen cloth comes out on the vibratory sieve of below, midline position at top cover is provided with the guide plate that cross section is a del, so just prevent that paddy from just beating the midline position at top cover, cause the phenomenon that straight up and down falls into again in the screen cloth, adopt the screen device of aforesaid way, can residual paddy from the rice bar that comes out, high efficiency can not cause the waste of grain, is provided with blade in addition on the skeleton in the exit of screen device, make that the rice bar is broken in the exit, form broken grass, the grass of being up to like this can be directly used in the farmland, need not to handle again, save manpower like this, improved efficient.
