Abstract
A vertical axial flow thresher of a full-feeding combine harvester reducing the sorting loss comprises a threshing chamber which is installed at the bottom plate of the full-feeding combine harvester, a longitudinal threshing cylinder, a concave screen plate and a sorting screen, a fan which is installed at the front part of the inside of the threshing chamber and is positioned at the bottom part of the sorting screen, an inferior material cabin which is positioned at the rear part of the threshing chamber and the bottom part of the sorting screen, and a secondary re-threshing conveying device, wherein the longitudinal threshing cylinder, the concave screen and the sorting screen are installed in the threshing chamber from up and down, and the output end of the secondary re-threshing conveying device is connected with the front part of the left side of the threshing chamber, and is positioned on the feeding transition plate of the threshing cylinder which is connected with the front end of the concave screen plate. According to the utility model, the output end of the secondary re-threshing conveying device is connected onto the feeding transition plate of the threshing cylinder which is connected with the front end of the concave screen plate instead of being connected onto the traditional sorting screen, and the thresher has the same rotation direction as that of the longitudinal threshing cylinder, i.e. the thresher rotates from the left side instead of the right side, thus not only greatly relieving the material processing strength of the sorting screen, reducing the loss of sorting materials, but also preventing the hidden trouble of blocking an output port.
Description
Technical field
The utility model relates to a kind of sheller unit of all feeding-in combine.
Background technology
The sheller unit of existing all feeding-in combine, its structure generally has threshing chamber, threshing cylinder from top to bottom is installed in the threshing chamber, concave grate, sorting screen, the threshing chamber space of sorting screen bottom is a cleaning room, the cleaning room leading section is equipped with fan, major ingredient storehouse and back time feed bin before the space of cleaning room is made of V shaped slab respectively, under the preceding major ingredient storehouse conveying screw feeder that is connected to the grain header silo is installed, under time feed bin of back secondary levels is installed and carries screw feeder, secondary levels carries the port of export of screw feeder to be connected with the secondary re-threshing roller, and the radial side of secondary re-threshing roller is connected with the secondary elevator and carries screw feeder.Secondary levels conveying screw feeder and secondary re-threshing roller and secondary elevator conveying screw feeder constitute incorporate secondary and take off conveying plant again, its secondary elevator carries the port of export of screw feeder to be connected to the threshing chamber right side and facing to the space between concave grate and the sorting screen, thereby the cereal that drops in time feed bin of back is cleaned through sorting screen once more.The sheller unit of said structure is divided into transverse axis streaming and longitudinal axis streaming according to the arrangement direction of its threshing cylinder, what be that the threshing cylinder level is horizontally placed in the threshing chamber, its axis becomes 90 degree with the grain header direction of advance is the transverse axis streaming, is longitudinal axis streaming and the threshing cylinder level vertically places in the threshing chamber, its axis parallels with the grain header direction of advance.Longitudinal axis streaming sheller unit is the comparatively novel sheller unit of present all feeding-in combine configuration, and its major advantage is the center of gravity connection and reasonable arrangement, and rotating speed is lower because threshing cylinder is long, thereby the threshing percentage of damage is low and the cereal entrainment loss is few.And the major defect that exists is that the more traditional transverse-axis-flow sheller unit of grain cleaning loss is big, reason is because the vertical threshing chamber of putting threshing roller structure of level is narrower than the threshing chamber width of the horizontal threshing roller structure of level, and threshing chamber length is substantially the same because of the restriction of installation site, thereby the sorting screen area of longitudinal axis streaming sheller unit is littler than the sorting screen area of transverse axis streaming sheller unit, when cleaning inventory one regularly, its cleaning loss also with regard to corresponding than transverse axis streaming sheller unit height.
Summary of the invention
The purpose of this utility model provides a kind of longitudinal axial flow threshing device of whole-feed combine harvester that reduces cleaning loss.
Technical solution of the present utility model is: comprise the threshing chamber that is installed on all feeding-in combine chassis, from top to bottom be installed on longitudinal threshing cylinder, concave grate, sorting screen in the threshing chamber, be installed on fan anterior in the threshing chamber, that be positioned at the sorting screen bottom, inferior feed bin and the secondary that are positioned at threshing chamber rear portion, sorting screen bottom take off conveying plant again, and secondary take off again the output of conveying plant be connected in the threshing chamber left side anterior, be positioned at above the threshing cylinder feeding rebound that is connected with recessed sieve plate front end.
Longitudinal threshing cylinder in the described threshing chamber is the open type ratch cylinder that is provided with 3～6 rooted tooth bars.
The beneficial effects of the utility model are: since the output that secondary is taken off conveying plant again from traditional sorting screen top reconfiguration above the threshing cylinder feeding rebound that is connected with recessed sieve plate front end, and change the left side into by the right side for consistent with longitudinal threshing cylinder direction of rotation, the material that has not only alleviated sorting screen is greatly handled intensity, thereby reduced the loss of cleaning material, the hidden danger of also having avoided delivery outlet to stop up.
