Description

The automatic clamping thresher of three rollers

Technical field

The utility model belongs to agriculture crops thresher machine.

Background technology

At present, crops thresher machine on the agricultural generally all is made up of frame, roller tube, cover plate, notch board, sorting screen, blower fan, transmission mechanism, but drawback such as the ubiquity selection by winnowing is unclean, and it is many to have impurity, and grain threshing clean rate and threshing performance are low.

The utility model content

The purpose of this utility model is to provide a kind of three rollers automatic clamping thresher, has the characteristics of clean rate, threshing performance, high efficiency, and stable working, safe and reliable.

The utility model thresher is by frame, last lower cylinder assembly, multiple threshing roller tube assembly, cover plate, the notch board assembly, blower fan, the feeding platform, automatic clamping conveying mechanism, the Lysimachia sikokiana plate, the sorting screen assembly, worm reducer and running part are formed, upper cylinder and lower cylinder assembly are installed on the frame, the roller tube is provided with the bow tooth, the coaxial main air blower that is provided with of lower cylinder tail end, terminal frame below does not fixedly mount worm reducer, cover plate is buckled on the roller tube, and be fixedly mounted on the frame, last lower cylinder one end is provided with the feeding platform, the other end is provided with the Lysimachia sikokiana plate, the notch board assembly is located by connecting on below the frame by regulating bolt, the sorting screen assembly is set below the notch board; Automatically the clamping conveying mechanism is made up of major and minor two clamping bands, and the expansive force spring assembly is set respectively on the clamping band, and main folder is held band and is installed on the frame by dialling standing grain gear wheel and sprocket bearing, drives sub-folder by friction and holds band; The frame left side is equipped with multiple threshing roller tube assembly, and coaxial being provided with of multiple threshing roller tube tail end taken off blower fan again, the horizontal installation of main air blower, and fan outlet is relative with multiple threshing roller tube charging aperture.

The utility model advantage is:

1, owing to adopted three roller tube threshings, cereal is combed simultaneously through upper and lower roller tube bow tooth beaten, increase comb and beat density, take off again through the 3rd roller again, thereby improved grain threshing performance, clean rate;

2, worm reducer is other hangs on the frame, replaces thresher gearbox in the past, makes horizontal fan outlet relative with multiple thresher charging aperture, is convenient to cereal and enters from air outlet and take off a roller threshing selection by winnowing once more again.

Embodiment

As shown in the figure; thresher is by frame 21; upper cylinder 11; lower cylinder 7; cover plate 22; notch board assembly 16; main air blower 18; multiple threshing blower fan 3; multiple threshing roller tube 4; feeding platform 9; automatic clamping conveying mechanism 10; Lysimachia sikokiana plate 14; worm reducer 13; sorting screen assembly 6 and running part are formed; install the lower cylinder assembly on the frame; cover plate is buckled on the roller tube; on the roller tube bow tooth is set; roller tube one end is provided with feeding platform 9; below the roller tube other end straw outlet is set; the lower cylinder tail end is coaxial horizontally to be provided with main air blower 18, and is provided with horizontal air outlet, and notch board assembly 16 is bolted on the frame 21 by adjusting; sorting screen assembly 6 is set below the notch board, drives by eccentric wheel 5.Automatically clamping conveying mechanism 10 is made up of major and minor two clamping bands, is respectively equipped with expansive force spring assembly 12 on two clamping bands, and main folder is held band and is installed on the frame by dialling standing grain gear wheel 8 and sprocket bearing, drives sub-folder by friction and holds tape running; The frame left side is equipped with multiple threshing roller tube assembly, and roller tube below is provided with takes off sieve nest 23 again, and multiple threshing roller tube tail end is provided with and takes off blower fan 3 again.

During operation, can adopt 18 horsepower diesels or 13 kilowatt motors is power, drive power input belt wheel 2, also can adopt tractor and drag farm work, the axle that can output power when adopting tractor to drag is connected on the spline power input shaft 1 by Hooks coupling universal coupling, drive lower cylinder spindle pulley 25, drive main sieve eccentric mechanism 5 respectively, make main sieve reciprocating, and, making the lower cylinder reverse rotation by communtation deceleration device 15 drive upper cylinder shaft pulleys 24, belt pulley 26 drives worm screw belt pulleys 27 behind the lower cylinder axle, worm screw drives worm gear, worm gear drives transmits clamping belt leather belt wheel 19, and then drives transmission clamping band chain wheel 20, drives and transmits the rotational automatic clamping cereal of clamping band, belt pulley also drives multiple threshing roller tube 4 simultaneously behind the lower cylinder axle, drives multiple threshing sieve nest by eccentric mechanism 17 simultaneously and moves back and forth.Worm reducer transmission speed ratio is that lower cylinder and grip belts transmission speed ratio are 20: 1.

When thresher is worked, cereal is placed on the feeding platform, send into automatic clamping conveying mechanism by dialling standing grain gear wheel 8, by the automatic clamping feeding of clamping band, under the effect of upper and lower roller tube bow tooth, grain separates with straw, and the whole straw that purifies after the cereal is discharged by Lysimachia sikokiana plate 14, and manual banding is used for sideline production production; Grain and the assorted leaf of smashing, by the notch board main sorting screen assembly that falls, not purifying foreign material sends into through the main air blower air outlet and takes off a roller tube assembly again and take off again, after taking off again, weeds are taken off roller tube centrifugal force again and are thrown away on the notch board, and weeds are taken off blower fan 23 again and blow out from straw outlet under the notch board, and the grain of rice is back to after taking off sorting screen again on the main sorting screen assembly, together enter discharging opening with the grain of rice of taking off for the first time, finish threshing course.
