A kind of shredding mechanism of the adjustable silage harvester of segment provided by the utility model, mainly includes：Forage
Pinch roll is to fixing roller 120, forage pinch roll to dancer 130, cutting roller 140, active drive sprocket, driven sprocket group, change
Fast tightener sprocket and speed change support sprocket wheel；Wherein, forage pinch roll fixes fixing roller central shaft 121 with cropper, forage folder
Tight roller connect fixing roller central shaft 121 with forage pinch roll by tensioning spring 520 dancer central shaft 131；By ensiling
Transmission designs between the forage feeding system and morcellating system of forage harvester make forage pinch roll pair into speed change gear
Fixing roller 120 and the rotating ratio of cutting roller 140 can change in a certain range, so as to make the segment of silage harvester long
Degree can be adjusted in a certain range, meet the requirement of different livestocks and various ensilages to staple fiber ppd；The utility model
Silage harvester power from forage pinch roll to being inputted, and drive operating system on fixing roller central shaft 121, operation
Remaining each equipment of system is from forage pinch roll to obtaining power on fixing roller central shaft 121.In addition to driving cutting roller 140
Transmission mechanism using the chain and sprocket driving device of variable-ratio except, operating system remaining transmission mechanism using fixed rotating speed than
Chain and sprocket driving device.
It drives in the transmission system of cutting roller 140 and contains the chain and sprocket driving device that rotating ratio can be adjusted step by step, which passes
Dynamic device by be installed on forage pinch roll on fixing roller central shaft 121 active drive sprocket 260, be installed on cutter roller center
Driven sprocket group on axis 141, is installed on position at the speed change support sprocket wheel 210 being installed on speed change support sprocket wheel central shaft 211
Speed change tightener sprocket 220 on adjustable speed change tightener sprocket central shaft and the driving chain for linking up above-mentioned drive sprocket
440 compositions；Wherein, driven sprocket group includes the first speed-changing chain 230, the second speed-changing chain 240 and third speed-changing chain 250 etc.
Speed-changing chain；Speed change tightener sprocket central shaft is according to the first speed-changing chain 230, the second speed-changing chain 240 and third speed-changing chain
250 different corresponding positions can be speed change tightener sprocket central shaft first position 221a, speed change tightener sprocket central shaft second
Position 221b and speed change tightener sprocket cental axial position 221c.
Chain guide groove 450 is open the center towards driving chain 440, and with the first speed-changing chain 230, the second speed varying chain
Wheel 240 or the 250 parallel installation of third speed-changing chain.Chain guide groove 450 can be under the action of selector gear, transverse shifting
Certain distance, and just with intending entering the change gear engaged in a plane；Under the guiding of chain guide groove 450, make
Driving chain 440 switches to the speed-changing chain for intending engagement from the current speed-changing chain for participating in transmission；Due to the switching of speed-changing chain
The variation of driving chain length needed for causing is by speed change tightener sprocket central shaft in speed change tightener sprocket central shaft first position
Between 221a, speed change tightener sprocket central shaft second position 221b and speed change tightener sprocket central shaft the third place 221c switch with
The relaxation caused by the variation of chain length or curtailment are made up, driving chain 440 is made to remain tensioning drive state.
Due to the transverse shifting of chain guide groove 450, change the speed-changing chain number of teeth that actual participation is driven, i.e., become in driven sprocket group
The number of teeth that the switching of fast sprocket wheel causes slave drive sprocket wheel to participate in transmission changes, and active drive sprocket 260 participates in the tooth of transmission
Number is constant, so the rotating ratio of chain drive also changes therewith, and the transformation of rotating ratio changes step by step by sequencing row are preset
The characteristics of.
According to above-mentioned transmission principle, when chain guide groove 450 reduces the speed-changing chain number of teeth into engagement, chain drive
Rotating ratio reduce, the rotating ratio of forage pinch roll fixing roller 120 and chaffcutter roller 140 reduces, the segment of silage harvester
Length reduces；When chain guide groove 450 increases the speed-changing chain number of teeth into engagement, chaindriven rotating ratio increase, grass
Expect that pinch roll fixing roller 120 and the rotating ratio of chaffcutter roller 140 increase, the staple fiber ppd of silage harvester increases.
Meet following relationship between staple fiber ppd and rotating ratio：In formula, l is the length of ensilage segment
Degree, ikIt is forage pinch roll to fixing roller and cutting roller rotating ratio, k=1,2 ..., r1Fixing roller for forage pinch roll centering
Radius, N be the cutting roller blade number of one week；Wherein,n1It is forage pinch roll to the rotating speed of fixing roller, n2
For the rotating speed of cutting roller, zDN-kFor the number of teeth of speed-changing chain, k=1,2 ... ..., zDRThe number of teeth for drive sprocket；Staple fiber ppd with
The formula of rotating ratio reflects ensilage staple fiber ppd l with forage pinch roll to fixing roller 120 and 140 rotating ratio i of cutting rollerk
The relationship of variation, forage pinch roll is to the radius r of fixing roller 1201It is received with the cutting roller blade number N of 140 1 weeks for ensilage
The structural parameters of machine operation system are obtained, once it is determined that get off to change in the process of running, but can be oriented to by chain
The transverse shifting of slot 450 changes the speed-changing chain for entering engagement, that is, changes the speed-changing chain number of teeth z for participating in transmissionDN-k, Jin Ergai
Become forage pinch roll to fixing roller 120 and 140 rotating ratio i of cutting rollerk, alloing its rotating ratio, step becomes in a certain range
Change, therefore the length of ensilage segment can also there are one the sequences selected.
