Abstract
The utility model relates to a pin wheel type multi-duty thresher roller adopted in the harvester, belonging to the thresher roller, the roller has four steel pans and four gear racks which are all connected with the steel pans through the coupling, the gear racks are equally arrayed on the excircle of the steel pans; pin wheels are welded on the gear racks, and the pin wheels are respectively welded on the two corresponding gear racks with the number of 11 and 10, the arrays of the steel pans and the pin wheels are that the inlet side is dense and the outlet side is sparse. The utility model has the advantages as follows: 1. simple structure, convenient in operation and use, no need to replace the roller when cropping and threshing the rice and wheat, really realizing one roller, multiple uses; 2. saving the making supplies and the making cost, the feeding of the roller is over half less than the axial flow roller, one third less than the pin wheel roller, reducing the manufacturing burden; 3. improving the cropping and threshing rate, the average pure threshing rate is more than 99.5 percent, the cropping and threshing speed is increased by 10 percent, compared with the former roller, the enwinding rate is reduced by more than 60 percent; 4. extending the service time, the service time of the roller and the bearing are extended one to two times.
Description
Technical field
The utility model relates to a kind of combine sheller unit, and a kind of specifically 2 profile shaft streaming twin-roll combine needle teeth types are used thrasher drum more.
Background technology
The axial-flow type drum of original 2 profile shaft streaming twin-roll combines is made up of tube axle, steel plate, sieve plate device, sieve plate, tube axle one face down bonding is connected to some quantity steel plates, opposite side is welded with two octagonal sieve plate devices, is connected with 8 screw thread band irons on each angle of sieve plate device.This axial-flow type drum rotation speed is step speed change; take off though can receive various types of grain; but because design is not very reasonable on the structure; the cylinder of this structure generally can only be used for receipts and take off wheat; other cereal receipts are taken off poor effect, and especially the adaptability to damp grain is lower, the cereal straw easily takes place twine; need after the winding to shut down to clear up time-consuming consumption worker in 2-3 hour.Taking off for the ease of paddy rice is received, is that 2 type combines are equipped with a kind of drum with pins specially.Former axial-flow type drum need be unloaded when receiving rice and change this drum with pins.Drum with pins is made up of tube axle, steel disk, ratch, finger, is connected with 4 steel disks on the tube axle, and the equidistant arrangement of steel disk is welded with six roots of sensation ratch on each steel disk, is welded with the curved finger of 15-17 root on each ratch, curved finger equidistant arrangement on ratch.This drum with pins is oil consumption owing to the reason in the design causes that resistance is big, machine burden is big, and straw pulverizes seriously, easily block, and dismounting also extremely inconvenience when changing the outfit.Above-mentioned two kinds of cylinders can only receive that to take off effect better to a kind of crops, and adaptability is lower, and exists problems such as mechanical load is big, oil consumption is many, easy obstruction.
Summary of the invention
To be solved in the utility model is exactly that 2 profile shaft streaming twin-roll combines the axial-flow type cylinder, the needle teeth type cylinder that adopt at present all exist and receive that to take off crops single, problems such as mechanical load is big, oil consumption is many, easy obstruction.
Solve the technical scheme that its technical problem adopts: this cylinder has 4 steel disks, and 4 rooted tooth bars are arranged, and all is connected on the steel disk by coupling, and ratch equal portions on the cylindrical of steel disk are arranged; Be welded with the tooth pin on the ratch, the tooth pin is welded with 11 rooted tooth pins and 10 rooted tooth pins respectively on corresponding two rooted tooth bars, and it is close that the arrangement of steel disk and tooth pin is inlet side, and outlet side is dredged.
Described coupling has a groove on one side, groove diameter and ratch equal diameters, and the coupling another side has two holes, is the connecting hole of ratch and steel disk.
Beneficial effect: because it is close to have adopted the arrangement of steel disk and tooth pin to be inlet side, outlet side is dredged, arranging of tooth pin is 11 rooted tooth pins and 10 scheme on corresponding two rooted tooth bars, the utlity model has following advantage: 1, simple in structure, easy for operation, do not need to change cylinder when receipts are taken off paddy and wheat, really accomplish to use one more; 2, save making raw material and manufacturing expense, these cylinder materials lack over half than the axial-flow type cylinder, lack 1/3rd than the pin dental roller, greatly reduce manufacturing expense; 3, the rate of receiving, be temporarily released from one's regular work improves, and average filter effect reaches more than 99.5%, receives the speed of taking off and improves 10%, and the winding rate is twined probability than former cylinder and reduced more than 60%; 4, the life-span prolongs, and has prolonged 1-3 the service life of cylinder and bearing doubly.

Fig. 2 uses the thrasher drum end view for the utility model grain header with needle teeth type more.
Embodiment
Embodiment 1: this cylinder has 4 steel disks 4, and 4 rooted tooth bars 2 are arranged, and all is connected on the steel disk 4 by coupling 5, and ratch 2 equal portions on the cylindrical of steel disk 4 are arranged; Be welded with tooth pin 3 on the ratch 2, tooth pin 3 is welded with 11 rooted tooth pins and 10 rooted tooth pins respectively on corresponding two rooted tooth bars 2, and it is close that the arrangement of steel disk 4 and tooth pin 3 is import 1 side, exports 6 sides and dredges.
Described coupling 5 has a groove on one side, groove diameter and ratch 2 equal diameters, and coupling 5 another sides have two holes, are the connecting hole of ratch 2 with steel disk 4; There is the tube axis hole 7 of a connecting cylinder axle at described steel disk 4 centers.
Make the i.e. steel disk of tube axis hole 80mm, external diameter 320mm of internal diameter with the 8mm steel plate, steel disk is as the framework and the support of cylinder, along bore edges relative opening in the steel disk apart from 110mm, divide the perforating on steel disk of 6 equal portions, so that the connecting cylinder axle; Make a call to 4 groups of i.e. 8 eyes along steel disk outside fate 4 equal portions on steel disk, every group of pitch-row 50mm is in order to installing coupling.Be cut into long 120mm steel rod as the tooth pin with diameter 16mm round steel.Be cut into long 1450mm as ratch with diameter 33mm steel pipe.Make high 45mm, wide 80mm with thick 8mm steel plate, a broadside leaves diameter 33mm groove, makes a call to 2 holes in another broadside, and pitch-row is 50mm, is made into coupling.
During connection, ratch is put in the groove of coupling, and welded, 4 coupling distances are 370 * 400 * 535mm; Again with tooth pin vertical welding on ratch, tooth pin one side density is 130mm, opposite side is 145mm, the ratch of steel disk circumference correspondence welds 11 rooted tooth pins, in addition two root beads, 10 rooted tooth pins.Again steel disk and coupling are coupled together with bolt, axle is through the steel disk endoporus, fix with plate tooth flange.
