A kind of maize harvesting machine fruit cluster knot screen of angle adjustable
The present invention relates to the maize harvesting machine fruit of a kind of harvest equipment of standing crop Semen Maydiss, especially a kind of angle adjustable
Fringe knot screen.
With the development of science and technology, maize harvesting machine has been widely applied to the harvest corn operation in large area plot
In.When being harvested to Semen Maydiss using maize harvesting machine, its harvesting to roller by drop-down for corn stalk, pluck shedding fringe, part is broken
Leaf, disconnected straw are fallen into defeated fringe device together with fruit ear and are transported in peeling machine, cause in fruit ear mixed with substantial amounts of broken leaf with disconnected
Straw, it has impact on peeling efficiency.In order to the impurity such as broken leaf, disconnected straw are separated removal by fruit ear, at present, generally in defeated fringe
A wind removing machine is fixed in the end of device, is blown out by blasting action by the wind removing machine.But, the casing of wind removing machine is fixed
In defeated fringe device end, its wind direction angle is fixed, and the harvest time difference of Semen Maydiss cause its blade, straw dry and wet degree not
Same, there are problems that broken leaf is removed with disconnected straw halfway.
Content of the invention
There is broken leaf in order to overcome the wind direction angle of prior art wind removing machine to fix halfway with the removal of disconnected straw
Deficiency, the present invention provide a kind of jade of reasonable in design, simple structure, wind direction adjustable angle, Impurity removal thoroughly angle adjustable
