Description

Twin-roll threshing grass bruising machine

The utility model relates to a kind of twin-roll threshing grass bruising machine.

The two grow wheat threshers that generally use in the farming and pastoral area, Xinjiang at present.A kind of is spiketooth type list drum threshing machine.After the tangerine bar was hit threshing by nail tooth drum during this machine work, tangerine bar and grain were extruded simultaneously from the notch board eyelet and do not have unimpeded discharging opening, and threshing is clean but the time that material is treated in the cylinder storehouse is long, power consumption is many, the percentage of damage height, and productivity ratio is low, only has 150 kilograms/hour.

The single drum threshing machine of another kind of Xuzhou-1400 rasp bar formula, material is deviate from from two discharging openings respectively during work, and threshing is fast, and productivity ratio is at 600 kilograms/hour.Tangerine pole length after the separation is more than 30 centimetres, and it is more to carry grain secretly in the tangerine bar, generally also wants secondary just can purify for three times.More than two kinds of threshers can not solve threshing performance and deviate from the problem that wheat straw goes.

The purpose of this utility model is exactly the drawback that overcomes above two kinds of threshers, solves the exhausted shortage of farming and pastoral area, Xinjiang cattle and sheep winter-spring season forage grass, for a kind of twin-roll threshing grass bruising machine tool that thin short wheat straw is designed is laid in processing autumn and winter.

The utility model is made up of three parts sheller unit, cleaning plant, trash discharging apparatus.The installation of this three part is to be connected on the frame of threshing grass bruising machine by bolt and nut to finish realization.

The utility model is compared with above two kinds of types, its effect be can with little wheat stalk through the rubbing threshing of twin-roll and two concave grates with separate, efficient approximately can reach about 600 kilograms/hour, little wheat stalk after the separation becomes 1-3 centimetre thin short wheat straw after rubbing is pulverized, thereby has strengthened the palatability of cattle and sheep.

Now be described with reference to the accompanying drawings structure of the present utility model:

One, the structure of twin-roll threshing grass bruising machine:

The utility model complete machine housing is to adopt 1.5 millimeters thin plates to be riveted on 4 centimetres of angle steel frames of square frame shape 32,39.Collection granary 31 is unequal-sided tetragonal body volumes.Its material adopts 1.5 millimeters thin plates to make, and is fixed on frame 32 bottoms of cylinder and notch board below with bolt, nut.

(1) sheller unit: the threshing of (shown in figure one) wheat is made up of bar tooth spare 8, first power transmission shaft 9, the first bar dental roller 10, the first grizzly bar notch board 11, the first concave grate fixed pin shaft 12, charging aperture 13, spike-tooth spare 2, second nail tooth drum 3, second power transmission shaft, the second grizzly bar concave grate 5, the second concave grate fixed pin shaft 23, notch board central fixed shaft 7, electric machine support 14, first, second shaft transmission belt wheel 15, bearing, bearing block 16.

More than the position of two cylinders and two concave grates be in threshing machine top, being connected and fixed of drum member is to rely on bearing and bearing block to be fixed on the frame 32 with bolt and nut.The binding of two grizzly bar concave grates is to rely on the bolt and nut on the notch board fixed pin shaft to be fixed on the frame 32.Two 15 of drum pulleys are by key and key is horizontal is fixed on the power transmission shaft 49.

(2) cleaning plant: (shown in figure one) grain clean by winnowing machine 28, collection granary 31, hopper mouth 29, the roller 25 of winnowing, winnow be with 26, frame 32, winnowing machine discharging opening 24, roller bearing, bearing block 35,38 form.

The binding of cleaning plant is to rely on bearing, the bolt on the bearing block, the nut of three rollers to be fixed on 32 bottoms on the frame.

(3) trash discharging apparatus: the tangerine bar impurity impurities removal after (as shown in Figure 2) pulverizing is made up of impurities removal tube 18, bearing, bearing block 19, fan 20, fan pedestal 21, fan axle fastening bolt nut 22, airflow chamber 40, circular airflow chamber housing 41.

The connection of trash discharging apparatus: circle airflow chamber housing 41 is to be welded on the second nail tooth drum right side main casing, for the ease of its end cap 42 of dismounting, be to adopt screw to be fixed on the circular airflow chamber housing 41.Fan 20 is to rely on screw to be fixed on the fan pedestal 21.

Two, operation principle:

(1) threshing: the utility model has 13,33 2 grain wheat tangerines of two charging apertures outlet 18,24.Material enters from feeding mouth 13 during work.Because the first bar dental roller, 10 rotating speeds are low, make most of ripe grain through strike rubbing, the threshing of cylinder and notch board, separate.Fall into collection granary 31 through first order concave grate 11.The remaining difficult grain cane that comes off enters second nail tooth drum 3 together.The rotating speed of second nail tooth drum is higher, guarantees that all grain all take off to the greatest extent, and grain falls into after second group of grizzly bar concave grate 5 separates that the utilization of rotating speed difference of height changes belt between collection granary 31, the first cylinders 10 and the second tin roller 3, the wheel diameter size realizes.The working power of the utility model institute is generally at 11 kilowatts-13 kilowatts.

(2) cleaning of grain: separate through second level concave grate 3, tiny emersion object comprises: the short cane grain husk of grain shell.The work of cleaning of impurity is to rely on the hopper mouth 29 lower end belt winnowing machines 28 of second concave grate, 5 collection granaries 31 to finish.

(3) impurities removal of tangerine bar: the impurities removal of tangerine bar is to rely on 25 ° of-45 ° of dextrorotation guide plates and the spike-tooth 2 that are provided with on the top cover to finish by the lead angle that 5 ° of-7 ° of dextrorotation are arranged on second nail tooth drum.Remaining wheat straw of being crumpled connects top cover 6 spiral guide plates and spike-tooth and arranges lead angles by 5 °-7 ° progressively be pushed to cylinder gas and roll chamber 40 1 ends on cylinder after the grain threshing.The suction that the wheat straw foreign material produce through airflow chamber's 40 fans 20 sucks airflow chamber 40 and blows out impurities removal tube 18 through fan wind-force again.

Twin-roll threshing grass bruising machine is after connecting the running of external power supply rear motor during use, and motor driving wheel 17 is passed to first, second drum pulley 15 and winnowing machine belt 34 to power through the triangle taut band.After sheller unit, cleaning plant, trash discharging apparatus are run well, finish rubbing, the pulverizing of threshing, the tangerine bar of wheat, the impurities removal process of wheat straw.
