Abstract

The utility model discloses a threshing tumbling cylinder, which comprises a housing and a tumbling cylinder body installed in the housing. The tumbling cylinder body is fixed to a rotating shaft through end covers arranged at both ends thereof, ventilation inlets are also formed on the end covers in the radial direction of the end covers; an outwards extending blade is arranged on the radial side edge on the same side as each ventilation inlet; and an air outlet is formed on the tumbling cylinder body and an exhaust outlet is formed on one side of the housing. The threshing tumbling cylinder with the structure discharges sundries from the exhaust outlet. Compared with the discharge manner of the prior threshing tumbling cylinder that the sundries are squeezed into an auxiliary tumbling cylinder until the space between the tumbling cylinder body and the housing is filled with the sundries. The utility model has smaller required driving force, thereby saving energy. Besides, the combine harvester with the threshing tumbling cylinder eliminates the auxiliary tumbling cylinder, thereby realizing the simplification of the structure.

Description

A kind of threshing cylinder

Technical field

The utility model relates to agricultural harvesting machinery, is specifically related to the threshing cylinder of combine.

Background technology

At present, the barrel two ends of the threshing cylinder of combine are provided with the end cap of sealing, and barrel is connected in the rotating shaft by end cap, be connected with the threshing tooth on the outer weekly form of barrel, barrel is positioned at shell, and the barrel below is provided with considers sieve, and the below of considering sieve is provided with screw feeder.Cereal fringe head is delivered to by clamping chain and is considered between sieve and the barrel, grain disengaging fringe head drops to secondary worry sieve through considering sieve after hitting of threshing tooth bumped, rubbed, the filtration grain of considering sieve through secondary falls in the screw feeder and by screw feeder to be exported, and the fringe head that still has grain is considered that sieve then falls in the straight screw feeder and sent to consider between sieve and the barrel through oblique screw feeder through secondary and carries out the secondary threshing.Assorted surplus in the detach procedure discharged by the spiral impurities removal auxiliary cylinder that is connected barrel one side.The assorted surplus discharge of the threshing cylinder of last structure is undertaken by auxiliary cylinder, only assortedly just can be extruded into auxiliary cylinder, the bigger driving force of rotation need of barrel after surplus filling up between barrel and shell.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned defective, provides a kind of barrel driving force less threshing cylinder.

For solving the problems of the technologies described above, the utility model provides a kind of threshing cylinder of following structure, comprise shell, cased barrel, barrel is fixed in the rotating shaft by the end cap at its two ends, its design feature is: be periphery on the described end cap along the radially air inlet of trend of end cap, the radially side of each air inlet the same side is provided with overhanging blade, and barrel is provided with exhaust vent, and a side of shell is provided with exhaust outlet.

The threshing cylinder of said structure; air entered through air inlet under the effect of blade when barrel rotated, and blew out through exhaust vent, and the wind that blows out can make grain or grain ear separate at the exhaust outlet place; grain that proportion is bigger or grain ear are fallen and are considered on the sieve, and the lighter assorted surplus shell that is blown of proportion.The threshing cylinder of this structure realizes by exhaust outlet assorted surplus discharge, need wait until that with existing threshing cylinder filling up the discharge mode that assorted Yu Houcai is extruded into auxiliary cylinder between barrel and shell compares, and the required driving force of barrel is less, can save the energy.Moreover, use the combine of the threshing cylinder of said structure to save auxiliary cylinder, thereby can make the simple in structure of complete machine.

In order to regulate the assorted surplus velocity of discharge, the both sides of described exhaust outlet are hinged with current limiting plate.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Threshing cylinder as shown in drawings, comprise shell 1, be contained in the shell 1 and be fixed in barrel 2 in the rotating shaft 9 by end cap 3, be evenly equipped with threshing tooth 10 on the outer peripheral face of barrel 2, rotating shaft 9 is connected with the power set power of combine, the below of barrel 2 is provided with the screen 11 affixed with shell 1, the air inlet 4 that is periphery on the end cap 3 and radially moves towards along end cap 3, air inlet 4 is 14, the quantity of air inlet 4 can be decided according to instructions for use, each air inlet 4 is provided with overhanging blade 5 along the side of end cap 3 the same side radially, and air inlet 4 and blade 5 are formed by the disposable punching press of mould.Interval at threshing tooth 10 on the barrel 2 evenly is provided with exhaust vent 6, and a side of shell 1 is provided with exhaust outlet 7.The both sides of described exhaust outlet 7 respectively are hinged with current limiting plate 8, by regulating opening degree and the opening angle that hinge can change two current limiting plates 8.The hinge dragon 12 that is used to discharge grain is equipped with in the bottom of shell 1.

Claims
