The utility model belongs to field of agricultural machinery; more particularly to a kind of corn kernel machine threshing cylinder; including front end axle and rear end axle; front end axle imports cone cylinder by flange connection; rear end axle connects impurities removal roller by flange; import the ratch connection by distribution between cone cylinder and impurities removal roller; ratch helically conical distribution; connected between ratch by spoke disk; the diameter of spoke disk increases successively from front to back; finger is distributed with ratch, finger length is shortened successively from front to back, and the end of finger is cased with rubber cap.The threshing cylinder body that the utility model ratch is formed is in cone, and the anterior big rear portion of cylinder-concave clearance is small, and body is larger before the adaptation non-threshing of corn ear, the smaller this special case different from other crops of body after threshing.The percentage of damage of seed can effectively be reduced.
Description
Technical field
The utility model is related to a kind of corn kernel machine threshing cylinder, belongs to field of agricultural machinery.
Background technology
From the point of view of efficiency and economy, convenience from corn mechanical harvest, direct harvesting corn seed is following corn machine
The developing direction of tool harvest.But corn kernel harvester is harvesting the problem of aspect of performance still has many at present.Wherein
One major problem is that corn ear threshing present in threshing course is net, seed damage, high percentage of impurity the problem of.Its
The workpiece being mainly concerned with is the threshing cylinder of corn kernel machine.
Utility model content
The technical problems to be solved in the utility model is：Offer one kind can solve corn kernel machine and be deposited in threshing course
Threshing is net, seed damage, the high problem of percentage of impurity corn kernel machine threshing cylinder.
Corn kernel machine threshing cylinder described in the utility model, including front end axle and rear end axle, front end axle pass through flange
Connection imports cone cylinder, and rear end axle connects impurities removal roller by flange, imports the ratch by distribution between cone cylinder and impurities removal roller
Connected between connection, ratch helically conical distribution, ratch by spoke disk, the diameter of spoke disk increases successively from front to back, ratch
On finger is distributed with, finger length is shortened successively from front to back, and the end of finger is cased with rubber cap.
It is bolted between described importing cone cylinder and ratch, between impurities removal roller and ratch.
Described ratch is bolted spoke disk.
Described finger includes curved finger and straight-tooth is followed closely, and curved finger is arranged on the first half of ratch, the bending side of curved finger
To the direction of rotation with curved finger on the contrary, straight-tooth nail is installed in the latter half of of ratch.
Described ratch selects the square steel of strip.
Described spoke disk is evenly arranged between importing cone cylinder and impurities removal roller.
Described finger is threaded with ratch junction, is connected between finger and ratch by nut.
Described ratch, finger and importing cone cylinder is in clockwise direction screw arrangement, the incoming side of rotating counterclockwise of front end axle
To.In face of front end axle, the rotation direction of the threshing cylinder of ratch composition is counterclockwise.
Operation principle and process：
Threshing cylinder is assemblied in sheller unit, is up and down cylindric concave grate.Threshing cylinder rotates during harvest operation,
Corn ear import cone cylinder helical blade effect under enter in sheller unit, and finger and concave grate impact and rub
The lower threshing of effect, seed is fallen by concave grate, and the debris such as corncob and bract after threshing is discharged to impurities removal roller backward
Sheller unit.
The beneficial effects of the utility model are：
1st, the threshing cylinder body of ratch formation is in cone, and the anterior big rear portion of cylinder-concave clearance is small, adapts to corn ear not
Body is larger before threshing, the smaller this special case different from other crops of body after threshing.Seed can effectively be reduced
Percentage of damage；
2nd, it is in bending positioned at the anterior finger of ratch, and is furnished with rubber cap at top, can also effectively reduces seed
Percentage of damage；
3rd, the anterior cone cylinder that imports effectively can import material in the threshing cylinder body of ratch composition；
4th, the overall ratch of threshing cylinder, the setting of finger, ratch and finger are distributed, can effectively improved in the shape of a spiral respectively
The balance of the efficiency of threshing, threshing performance and threshing cylinder.
Brief description of the drawings
