Abstract
The utility model relates to a stubble shredding device, which can be used for shredding the stubble of crop in ridges. Because the stubble shredding device comprises the rear edge of forwards moving of a knife roller, a gathering rake which can block off the stubble, and a cutting knife which is fixed to the gathering rake and can shred the stubble by matching with the knife of the knife roller; the knife roller of the utility model has a secondary stubble shredding ability, and can prevent the occurrence of stubble leaving; therefore, the utility model has a high stubble shredding efficiency.
Description
A kind of " broken stubble device " of using by the stubble cleaner of the broken field of tractor-drawn ridge crops stubble.
Known prior art is several the stubble in straight knife and the tulwar high speed rotating impact grinding ridge with on the rotor that is equipped with on the stubble cleaner driving shaft.Because rotor moves in rotation, can only smash stubble the preceding.In addition, the interval of distribution cutter can produce the space, and the stubble situation all can take place behind the cutter blunt to leak, so the effect of the broken stubble of this technology is relatively poor.
At the deficiencies in the prior art, task of the present invention is that a kind of broken stubble of design is effective, and the efficient height is simple in structure, the broken stubble device of reliable in function.
Broken stubble device of the present invention, be on the driving shaft that is fixed on by frame support, during rotating, moves rotor straight by being equipped with on the hub, tulwar, stubble in the broken ridge, being connected in frame is provided with and follows at rotor reach trailing edge place, the cutter that the rake that can block Lou stubble is arranged and fix it on rotor interacts, the dull and stereotyped cutting knife composition that leaks the stubble fragmentation.
Rake is to be fixed in frame and coaxial the putting of driving shaft by being enclosed within, and an end has adjusts the swing arm of blade with two slotted holes in rotor outer rim gap.The rake beam be welded with the steel bar rake teeth of gap length unanimity and have with swing arm on two slotted holes with bolt closing, be used for tilling depth and change the circular arc slotted hole of adjustment angle and the connecting ear of circular hole.Be connected in good grounds tilling depth variation between swing arm and frame, but the control rake teeth lifts or the lifting buffer gear of down position and elastic buffer displacement is formed.
The lifting buffer gear is by being fixed in the cross bore piece of adorning on the frame bearing pin and penetrating in another hole of cross bore piece, be lined with in the sleeve pipe of elastic component, limit the position by two nuts, the screw rod composition that the other end connects with the bearing pin that is fixed on the rake.
Broken stubble device of the present invention owing to be provided with rake at the reach trailing edge place of rotor and fix cutting knife on it, after stubble being hugged block, is broken under the interaction of the tulwar that goes back to and the cutting knife of fixing.This technology is compared with prior art, and rotor has broken batch of ability twice.So, the crushing efficiency height of this device stubble, effective, simple in structure, dependable performance.
Broken stubble device has following accompanying drawing:
Fig. 1 is the structural representation sketch of broken stubble device.
Fig. 1 is the embodiment of this broken stubble device, is loaded on by the rotor on the driving shaft of rack support (1) and is enclosed within driving shaft coaxially, is fixed in putting of frame, and an end has the swing arm (7) of two slotted holes.Corresponding with row spacing, the rake beam (10) that closes dull and stereotyped cutter (9) is welded with the steel bar rake teeth (11) of gap length unanimity and has with swing arm (7) two slotted holes by bolt by bolt closing, be used for tilling depth and change the circular arc slotted hole of adjustment angle and the connecting ear (8) of circular hole.Be connected between swing arm (7) and frame, one is the cross bore piece (4) that bearing pin (2) is gone up dress; The other end is with the screw rod (3) that is set with in bearing pin (2) and another hole that penetrates cross bore piece (4) that swing arm (7) is connected in elastic component (6) cover (5), with two positions of nut adjustment cover (5) on screw rod (3), realize the position of lifting and descending of control rake teeth (11), guarantee that tilling depth is in the appropriate location when changing.
Claims (3)
1, a kind of be used for " broken stubble device " of using by the stubble cleaner of the broken field crops of tractor-drawn stubble, be loaded on the driving shaft by rack support, move in the rotation, be fixed on the rotor that is used for broken ridge stubble that constitutes on the hub by straight, tulwar, the invention is characterized in, be connected on the frame, follow at rotor reach trailing edge place, be provided with the rake that can block Lou stubble and fix on it, interact, will leak the broken dull and stereotyped cutting knife of stubble with the cutter of rotor.
2, according to the broken stubble device of claim 1, the invention is characterized in, building rake is to be loaded on putting on the frame by being enclosed within driving shaft is coaxial, one end has the swing arm of two slotted holes adjusting cutting knife and rotor outer rim gap, the rake beam is welded with the rake teeth of spacing length unanimity, close with the bolt handle with having with swing arm two slotted holes, be used for tilling depth and change the circular arc slotted hole of adjustment angle and the connecting ear of circular hole, be connected in good grounds tilling depth variation between swing arm and frame, but the control rake teeth lifts or the lifting buffer gear of down position and elastic buffer displacement is formed.
3, according to the broken stubble device of claim 2, the invention is characterized in, the lifting buffer gear is by the cross bore piece of installing on the bearing pin that is fixed in frame and penetrates in another hole of cross bore piece, be lined with in the sleeve pipe of elastic component, limit the position by two nuts, the other end is formed with the screw rod that the bearing pin that is fixed in the swing arm connects.
