Abstract
The invention discloses a longitudinal axial flow threshing device of a whole-feed combine harvester. A charging chamber connected with a threshing chamber into a whole is added between the upper end of a middle conveying trough and the front end of a longitudinal threshing cylinder; the feeding chamber is internally provided with a transverse charging cylinder; the upper end of the middle conveying trough is connected with the inlet of the charging chamber; the bottom surface of the outlet of the charging chamber is connected with a concave sieve plate by a transition plate; the output end of a secondary re-threshing transporter is connected to the front part of the left side of the threshing chamber and is connected above the transition plate. Because of adding the charging cylinder, the improved threshing device of the invention greatly strengthens feed speed and throwing strength to the threshing cylinder charging so as to effectively avoid the detect that the longitudinal axial flow threshing chamber of the whole-feed combine harvester has large possibility of blocking; meanwhile, the output end of the secondary re-threshing transporter is connected above the charging transition plate of the threshing cylinder connected with the front end of the concave sieve plate instead of being above the traditional sorting screen, thus greatly lightening the material processing strength of the sorting screen, and reducing material sorting loss.
Description
Technical field
The present invention 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, and threshing cylinder, concave grate, sorting screen from top to bottom are installed in the threshing chamber, and 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 were equipped with the conveying screw feeder that is connected to the grain header silo before the space of cleaning room was made up of V shaped slab respectively under the preceding major ingredient storehouse, under time feed bin of back secondary levels were installed and carried 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 is carried the port of export of screw feeder to be connected to the threshing chamber right side and is faced toward 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 and grain header direction of advance parallel.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 few with the cereal entrainment loss.And one of shortcoming 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 narrow width of the threshing chamber of threshing roller structure than the horizontal threshing roller structure of level of putting 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, and when cleaning inventory one regularly, its cleaning loss is also just corresponding high than transverse axis streaming sheller unit; Two of the shortcoming that exists is that crop feeding direction becomes 90 degree with the direction of rotation of threshing cylinder; Smoothness not as the horizontal structure of level; Adding the interior conveying cylinder linear velocity of middle delivery chute that is articulated in before the threshing chamber, promptly to shed power inadequately not enough, and deficiency is so that threshing cylinder fully grasps straw, for remedying this defective; The existing vertical feeding Duan Jun that puts threshing cylinder is designed to taper and band screw feeder blade; But effect is still not ideal enough, promptly when the harvesting long-stalked crop particularly lodges, during the special circumstances of the ill crop of stem stalk, the threshing cylinder feeding mouth still can take place stop up.
Summary of the invention
The object of the invention provides the superior more reliable longitudinal axial flow threshing device of whole-feed combine harvester of a kind of performance.
Technical solution of the present invention 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 anterior in the threshing chamber, as to be positioned at sorting screen bottom fan; At the threshing chamber rear portion, the cleaning room time feed bin and the secondary of sorting screen bottom take off conveying plant and the middle delivery chute between the ceding of Taiwan and longitudinal threshing cylinder again; Be provided with the feeding chamber that links into an integrated entity with threshing chamber between delivery chute upper end and the longitudinal threshing cylinder front end in the middle of said; Horizontal feeding cylinder is installed in the feeding chamber; Delivery chute upper end, centre is connected with the feeding chamber import mutually, and feeding chamber outlet underrun rebound is connected with concave grate, and said secondary takes off the secondary elevator of conveying plant again and carries the screw feeder output to be connected in front portion, threshing chamber left side, is positioned at the rebound top.
Longitudinal threshing cylinder in the said threshing chamber is the open type ratch cylinder that is provided with 3～6 rooted tooth bars.
Horizontal feeding cylinder in the said feeding chamber is open type ratch cylinder or open type vane drum.
The ratch of said open type ratch feeding cylinder is 3～6, or the blade of open type blade feeding cylinder is 2～4.
Blade and its centre of the drum's axis of the ratch of said open type ratch feeding cylinder or open type blade feeding cylinder are the α angle.
The invention has the beneficial effects as follows: since the secondary elevator that secondary is taken off conveying plant again carry the screw feeder output from traditional sorting screen top reconfiguration above the threshing cylinder feeding rebound that is connected with the concave grate 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; Set up the horizontal feeding cylinder of high speed rotating in the threshing chamber import, strengthened greatly to the speed of threshing cylinder feeding with shed dynamics, thereby avoided the disadvantage of all feeding-in combine longitudinally axial flow threshing chamber inlet easy blocking effectively; Simultaneously, the ratch of feeding cylinder or blade and cylinder axis design certain included angle have been corrected because of being partial to the uneven problem of the material conveying that causes on ceding of Taiwan right side in middle delivery chute installation site.
