Abstract
The utility model discloses an axial flow type sheller device of a cereal combine harvester. Barriers which protrude from the screen surface and arranged in a circle are installed on a cambered concave screen deck of the device. The back part of the discharging port is not provided with any glass discharging wheels. The barriers can prevent cereal from doing helical motion on the screen deck when the cereal is threshed, and can compel the cereal to do circle motion only, which prolongs the disengaging time of the cereal. The stalk of the cereal can be discharged out of the machine by the centrifugal motion created by self rotation when the stalk arrives at a discharging port. The sheller device has the advantages that the utility model can enhance the separation rate of the cereal and decrease the power consumption of threshing. The block of the discharging port is difficult to occur.

The shortcoming of this sheller unit is: (1) is in threshing course, the first half of its threshing cylinder and arc concave grate has been finished the threshing of cereal and separating of most of grain, and the latter half of separation of just finishing remaining fraction grain, but consume and first half power much at one, therefore the separative efficiency of this sheller unit is lower, and the power that is consumed is higher; When (2) grain stalk arrives the outlet place, because the traction action of screw of self and discharge cane, the part cane just is not discharged from from outlet through the abundant separation of arc concave grate end, has reduced the availability of concave grate, has increased the percent of loss of grain; (3) grass-removing wheel need consume certain power, and easily stops up because of outlet takes place for it.
Purpose of the present invention is exactly at above-mentioned shortcoming, provides a kind of and can improve arc concave grate separative efficiency, reduces the threshing power consumption and is difficult for taking place the novel grain combine axial-flow type sheller unit that outlet stops up.
For achieving the above object, the present invention takes to install on the arc notch board compass screen surface of sheller unit and protrudes from compass screen surface and arrange the barrier with certain intensity that circularizes, this barrier can play obstruction cereal when threshing for the helical movement on arc notch board compass screen surface, and force it to make circular motion, prolong its disengaging time on the notch board compass screen surface; In addition, grass-removing wheel no longer is set at the rear of outlet, utilize grain stalk centrifugal motion that rotation on the cylinder produces from outlet directly with its discharge machine outside.
Above-mentioned barrier adopts 1 ring or encircles the dividing plate effect more better.Dividing plate preferably be arranged to drum shaft to vertical, it is for the helical movement so both to have hindered cereal effectively, and the resistance that cylinder rotation is produced is also minimum.The cornerite of dividing plate can also can be equal to or greater than the cornerite of concave grate, but be advisable with close less than the cornerite of concave grate.
Along with the raising of arc concave grate separative efficiency, just can correspondingly shorten the length of concave grate, reduce the threshing power consumption from another point of view.Generally can take to shorten the concave grate of threshing cylinder end, and adorn a ring dividing plate at the terminal surface of concave grate, this divider upright is lower than the distance of compass screen surface to roller tube highly slightly in compass screen surface, and cornerite equates with the cornerite of concave grate.Adopt the sheller unit of this structure, outlet preferably is opened in the back lower place of threshing cylinder.
The advantage of grain combine axial-flow type sheller unit of the present invention is: the separation rate that (1) has improved grain, reduced percent of loss; (2) reduced the threshing power consumption; (3) being difficult for taking place outlet stops up.
Below in conjunction with accompanying drawing embodiments of the invention 1 and example 2 are described in further detail.
