Abstract

The utility model provides an apparatus for cutting stalk into pieces, which is matched with an axial flow drum-type combine harvester. The utility model comprises a guide 1 with a guide plate 3 inside, a cutting body 2 with a group of fixed knives 5 on one end, a throwing device 6 on the other end, and a middle part provided with a movable knife rollers 7. The knife roller 7 is provided with multiple groups of movable knives 12. The device can cut stalks and sow on land behind the harvesting land while the harvester removes grasses. After compaction, organic humic substances of soil can be effectively improved; the soil structure can be improved and land capability can be increased. The utility model has the advantages of simple structure, reasonableness, easy fabrication, reliable performance, less pollution, convenient generalization and use, etc.

Description

Apparatus for cutting stalk into pieces

The utility model relates to a kind of shredding mechanism, particularly relates to a kind of and the matching used shredding mechanism of axial flow cylinder-type (being middle-size and small-size) combine.

The Ministry of Agriculture of country also promotes cane in China as new agricultural technology in the field.Yet domestic Apparatus for cutting stalk into pieces can only be with large-scale to cut the streaming combine supporting, and its structure mainly is that several hammer leaves of flexibly connecting on the live roll by (3000-5000 rev/min) rotation at a high speed remove to impact cane and realize the chopping target.This matching requirements combining tail fairing supporting with it must have certain rigidity, and extremely tight to the requirement for dynamic balance of live roll, and this will bring certain difficulty to manufacturing.In recent years along with the adjustment of rural economic structure, a middle-size and small-size axial-flow combine harvester market occupancy volume and day huge increasing, the proportion that machine is received area is also quite big, but does not still have the Apparatus for cutting stalk into pieces supporting with it so far.The cane of this part machine receipts have to large tracts of land burn for this reason.Not only wasted valuable resource, and the smog that burning produces certainly will cause environmental pollution, also will bring unnecessary influence simultaneously to fields such as aviations.

The purpose of this utility model is to provide a kind of special and supporting use of middle-size and small-size axial-flow combine harvester, require live roll rotating speed (below 3000 rev/mins) lower, the moderate relatively cane mincing and returning to the field of but realizing smoothly of requirement for dynamic balance is effectively avoided the Apparatus for cutting stalk into pieces of environmental pollution.

Scheme of the present utility model is as described below: this utility model comprises guide plate, moving knife roller, belt gear, bearing, knife rest, moving, stationary knife, minor axis and bolt, be provided with one group of stationary knife by guide way and one one end of establishing guide plate in one, the other end is provided with to be thrown the device that looses, central authorities and combines realization for the chopping bodies that are provided with many group moving knife on moving knife roller and the moving knife roller.Moving knife on its moving knife roller is symmetrical arranged for radially 180 ° of symmetries or 180 ° of intersections, and by vertical knife rest and minor axis it is flexibly connected.

The utility model is owing to taked the combination of guide way and chopping body and can regulate stationary knife and shed the device structure, this utility model can continuously also be broadcasted sowing the cane chopping on harvested soil in results, Lysimachia sikokiana equably with combine is supporting, plough anti-back cane is embedded in the soil tightly, effectively increase organic humus of soil, improve soil structure and increase soil fertility.Moreover, this utility model also has simple and reasonable, make easy to use, advantage such as reliable working performance reduces environmental pollution, and is easy to utilize.

Below in conjunction with accompanying drawing scheme of the present utility model is described in further details:

Fig. 1 is the overall structure schematic diagram of Apparatus for cutting stalk into pieces;

Fig. 2, Fig. 3 are the rotor and the moving knife structural representations of Apparatus for cutting stalk into pieces.

By Fig. 1-Apparatus for cutting stalk into pieces shown in Figure 3 is to be made of with chopping body 2 two parts (bolt is connected) guide way 1.Lean on top inclination fixed guide plate 3 in the guide way 1.And chopping body 2 one ends are provided with stationary knife 5 fixing on tool fixing frame 4 and this knife rest 4, and stationary knife 5 has an inclination downwards with knife rest 4.The other end is connected and fixed sheds device 6, sheds device 6 and is adjustable structure with stationary knife 5.Spread the chopping of throwing fabric width and adapting to different canes such as doing, wet in order to adjustment.The central authorities of chopping body 2 are provided with its axially parallel with tool fixing frame 4 moving knife roller 7, and moving knife roller 7 two ends are with bearing 8, and transmission mechanism 9 drives formed such as the belt pulley that connects on the engine spindle by axial-flow combine harvester, belt.The surface of moving knife roller 7 (as Fig. 2) radially 180 ° be arranged with four groups of vertical movable knife racks 10, on each movable knife rack 10 through bolt be minor axis 11 to connect two moving knife be double blade (this blade can be selected the double-sided blade flail knife), this moving knife 12 is interlaced with stationary knife 5.For guaranteeing the income of harvesting quality and reaper operator, must earlier the side shield of combine axial-flow type drum be removed during work.When cane is dished out to guide way 1 from the grass outlet of grain header axial-flow type drum, certainly will be subjected to stopping of guide way 3, cane is cushioned in guide way 1 and move to the chopping mouth place of chopping body 2 along the direction of guide plate 3, high speed (2706 rev/mins) rotation along with moving knife roller 7, cane is quickened, when moving to stationary knife 5 cutting edges that tilt to moving knife 12 examples, just carry out sliding cutting, realize the cane chopping.The wind-force that cane chopped leans on inertia own and moving knife roller 7 to give is thrown equably along the amplitude of shedding device 6 adjustment and is dispersed on the harvested soil.
