Embodiment
Fig. 1～Fig. 5 combines to have provided a kind of crude stalk chopper that can regulate feeding height automatically, comprises chopper assembly, charging spout 3, intake mechanism 4, gets rid of and throw device 1, gear 11, motor 6, belt transmission case 5 and frame 7.
The chopper assembly comprises the chopper housing 2 that is arranged on the frame 7, is respectively equipped with the import of chopper housing 2 and the outlet of chopper housing 2 on the chopper housing 2, and the throwing device 1 that gets rid of that is positioned at chopper housing 2 tops is connected with the outlet of chopper housing 2.Belt transmission case 5 is positioned at the left side of chopper housing 2, and the motor 6 that is positioned at chopper housing 2 belows links to each other with line shaft 51 through belt transmission case 5, and motor 6 is fixedly installed on the frame 7.The right side of chopper housing 2 is provided with tandem intake mechanism 4 and gear 11.Charging spout 3 is connected with the inlet of intake mechanism 4, and the outlet of intake mechanism 4 is connected with the import of chopper housing 2.
Import department at chopper housing 2 is provided with ledger-plate 10, and ledger-plate 10 is fixedly linked with frame 7.In chopper housing 2, be provided with movable knife rack 8, of Fig. 3, movable knife rack 8 comprises 3 supports 81 that become 120 ° each other, and the center of movable knife rack 8 and line shaft 51 are fixedly linked.The hammer leaf 14 of 1 L type is set respectively on each support 81; Hammer leaf 14 is realized being fixedly linked through bolt and support 81; 3 hammer leaves 14 form one and get rid of the throwing wheel, can the material after the chopping be thrown device 1 through chopper housing 2 with getting rid of successively, thereby throw away outside the whole shredding mechanism.A knife section 9 also is set respectively on the hammer leaf 14 of each L type, and knife section 9 is realized being fixedly linked through bolt and hammer leaf 14; Respective bolt holes on the hammer leaf 14 is U-bolt hole (being the bolt hole that fixes with support 81), can adjust hammer leaf 14 and the position of knife section 9 with respect to support 81 like this, guarantees that promptly it is adjustable that certain clearance and this gap are arranged between knife section 9 and the ledger-plate 10.Knife section 9 is a straight knife, the thick 8mm of blade.3 knife sections 9 that rotate together along with movable knife rack 8 match with ledger-plate 10, thereby form a cutter sweep, and ledger-plate 10 plays a supportive role when cutting.Therefore, the agricultural crop straw that gets in the chopper housing 2 from intake mechanism 4 is sheared by this cutter sweep.
The axle center overlaid of the center of circle of arc chute 41 and jackshaft 49 is O shown in Figure 5.One end of last feeding roller rocker shaft bed 43 links to each other with jackshaft 49, and the other end slides up and down along arc chute 41, and feeding roller 42 slides up and down thereby drive upward.
Gear 11 comprises the speed change roller gear group 13 and speed cone gear train 12 that transmission links to each other, and speed change roller gear group 13 links to each other with line shaft 51, and speed cone gear train 12 links to each other with the roll shaft that feeds roller 45 down.Speed change roller gear group 13 has acknowledgment copy to match with speed cone gear train 12, to adjust different speed ratios, makes down the rotating speed adjustable of feeding roller 45 whole, thereby the adjustable length of chopping material, is suitable for the chopping of multi-purpose agricultural crop straw.
The roll shaft of last feeding roller 42 is along with the vary in diameter of feeding material; Feeding roller rocker shaft bed 43 and regulating spring 44 are the center of circle (being the axle center of jackshaft 49) with O in the dependence, and R60mm is radius (being the radius of arc chute 41); In arc chute 41, slide up and down; Thereby can regulate stem stalk feeding height automatically, on feed roller 42 and down the centre-to-centre spacing of feeding roller 45 is adjustable between 75～144mm, be suitable for the different material feeding and also clamp.In Fig. 5, what the top M of arc chute 41 was corresponding is maximum (144mm) state of centre-to-centre spacing, and what the bottom N of arc chute 41 was corresponding is minimum (75mm) state of centre-to-centre spacing.
The operation principle of the crude stalk chopper that can regulate feeding height automatically of the present invention with the contents are as follows:
When motor 6 startings, power is passed to movable arbor 51 by belt transmission case 5, rotates thereby drive movable knife rack 8, and the knife section 9 of rotation matches with ledger-plate 10 and forms a cutter sweep.Above-mentioned power is passed to down the roll shaft of feeding roller 45 after speed change roller gear group 13 and speed cone gear train 12 slow down; The power that roll shaft obtained that feeds roller 45 down passes to the roll shaft of feeding roller 42 more successively through chain wheel set 47, jackshaft 49 and roller gear group 48, thereby makes feeding roller 42 and feed roller 45 down with fast reverse rotation.
The stem stalk is from charging spout 3 feeding, and with the compacting of stem stalk and be rolled into the import of chopper housing 2 automatically from intake mechanism housing 46, the knife section 9 that the stem stalk is rotated (under the supporting role of ledger-plate 10) shreds under the effect of last feeding roller 42 and feeding roller 45 down.3 hammer leaf 14 formed getting rid of are thrown wheel, and the material after will shredding is automatically thrown device 1 through chopper housing 2 with getting rid of successively, throws away outside the whole shredding mechanism.
Through the test, the chopping material granularity for less than 10.0mm account for 85%, meet the compression forming requirement.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
