Abstract
A longitudinal axial-flow threshing device of a whole-feed combined harvester is characterized in that a feeding chamber connected with a threshing chamber into a whole is additionally arranged between the upper end of an intermediate conveying trough and the front end of a longitudinally placed threshing rotary drum, a transversely placed feeding rotary drum is installed inside the feeding chamber, the upper end of the intermediate conveying trough is linked with an inlet of the feeding chamber; the bottom surface of an outlet of the feeding chamber is connected with a concave sieve plate through a transitional plate; and an output end of a secondary re-threshing conveying device is connected to the front on the left side of the threshing chamber and positioned above the transitional plate. After the improvement, the longitudinal axial-flow threshing device effectively avoids the shortcoming that an inlet of the longitudinal axial-flow threshing chamber of the whole-feed combined harvester is easy to block because the feeding rotary drum is additionally arranged to greatly enhance feeding speed and throwing force for the threshing rotary drum. Simultaneously, as the output end of the secondary re-threshing conveying device is changed to be connected above the threshing rotary drum feeding transitional plate connected with the front end of the concave sieve plate from being connected above a traditional sorting sieve, material processing strength of the sorting sieve is greatly relieved, and accordingly the loss of sorted materials is decreased.
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 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 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; 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, 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 purpose of this utility model 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 utility model is: comprise the threshing chamber that is installed on all feeding-in combine chassis, from top to bottom be installed on the longitudinal threshing cylinder in the threshing chamber, concave grate, sorting screen, be installed in the threshing chamber anterior, be positioned at the fan of sorting screen bottom, be positioned 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 described, horizontal feeding cylinder is installed in the feeding chamber, middle delivery chute upper end is connected mutually with the feeding chamber import, feeding chamber outlet underrun rebound is connected with recessed sieve plate, and described 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, be positioned at the rebound top.
Longitudinal threshing cylinder in the described threshing chamber is the open type ratch cylinder that is provided with 3～6 rooted tooth bars.
Horizontal feeding cylinder in the described feeding chamber is open type ratch cylinder or open type vane drum.
The ratch of described 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 described open type ratch feeding cylinder or open type blade feeding cylinder are the α angle.
The beneficial effects of the utility model are: 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 the speed of threshing cylinder feeding greatly and shed dynamics, thus the disadvantage of having avoided all feeding-in combine longitudinally axial flow threshing chamber inlet to stop up easily 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.
