In the utility model, by the forage pinch roll of silage harvester to being designed to float type, lead between roller pair
Tensioning spring 430 is crossed to connect；One in two rollers of forage pinch roll pair is fixing roller, and the position of central shaft is fixed on blueness
It stores on forage harvester；Another roll shaft is dancer, and central shaft can be with unit relative to the central shaft distance of fixing roller
The amount of forage is fed in time and is changed, elastic force and clamped forage of the central shaft distance between forage pinch roll pair by spring
Tension between balance determine.
Specifically, the characteristic of the present embodiment is mainly reflected in the forage pinch roll pair of silage harvester apparatus for work
Transmission device between fixing roller 120 and cutting roller 140 is stepless speed change device, and the rotating ratio between two rollers can be in certain model
Enclose interior consecutive variations.
Stepless speed change device in the present embodiment is pitch circle adjustable tape transmission device, belt driver by driving pulley,
Driven pulley and transmission belt 540 are formed.Wherein driving pulley is formed by fixing cone pulley 510 and movable cone pulley 520, and driving pulley can
Mantle wheel 520 can move under the action of initiative taper wheel acting device 530 along axis, so as to change the work of driving pulley half
Diameter.When initiative taper wheel acting device 530 make the movable cone pulley 520 of driving pulley to driving pulley fix cone pulley 510 close to when, actively
The radius of clean-up increase of belt wheel；When initiative taper wheel acting device 530 makes the movable cone pulley 520 of driving pulley to driving pulley fixed cone
Wheel 510 far from when, the radius of clean-up of driving pulley reduces.Driven pulley is formed by fixing cone pulley 550 and movable cone pulley 560, from
The movable cone pulley 560 of movable belt pulley can move under the action of driven cone pulley acting device 570 along axis, so as to change driven pulley
The radius of clean-up.It is leaned on when driven cone pulley acting device 570 makes the movable cone pulley 560 of driven pulley fix cone pulley 550 to driven pulley
When near, the radius of clean-up increase of driven pulley；When driven cone pulley acting device 570 makes the movable cone pulley 560 of driven pulley to driven
Belt wheel fix cone pulley 550 far from when, the radius of clean-up of driven pulley reduces.
The constraint of fixed length limitation of the also driven band 540 of change of driving pulley and the driven pulley radius of clean-up, i.e., actively
During the radius of clean-up increase of belt wheel, the radius of clean-up of driven pulley necessarily reduces or the radius of clean-up of driven pulley increases, main
The radius of clean-up of movable belt pulley necessarily reduces, and the constraint of fixed length of the driven band 540 of its increase and decrease amount.When the work half of driving pulley
Diameter increases, and when the radius of clean-up of driven pulley reduces, forage pinch roll becomes smaller to fixing roller 120 and the rotating ratio of cutting roller 140,
The staple fiber ppd of ensilage reduces；When the radius of clean-up of driving pulley reduces, and the radius of clean-up of driven pulley increases, forage
Pinch roll becomes larger to fixing roller 120 and the rotating ratio of cutting roller 140, and the staple fiber ppd of ensilage increases.
As shown in Figure 1, a kind of shredding mechanism of staple fiber ppd stepless adjustable silage harvester of the utility model
The course of work it is as follows：
When wish silage harvester staple fiber ppd become in short-term, need reduce forage pinch roll to fixing roller 120 with
The rotating ratio of cutting roller 140, i.e. requirement increase the rotating speed of cutting roller 140 or reduce rotating speed of the forage pinch roll to fixing roller 120,
By increasing the radius of clean-up of driving pulley, while reduce the radius of clean-up of driven pulley, that is, control the movable cone pulley of driving pulley
The acting device 530 on 520 sides moves toward one another two cone pulley generations, while controls the start on movable 560 side of cone pulley of driven pulley
Device 570 makes two cone pulleys generate mutually from movement, the amount of movement of initiative taper wheel acting device 530 and driven cone pulley acting device 570
The stringent limitation of driven 540 constraint of fixed length of band meets the control requirement that ensilage staple fiber ppd shortens.
When the staple fiber ppd for wishing silage harvester is elongated, need increase forage pinch roll to fixing roller 120 with
The rotating ratio of cutting roller 140, i.e. requirement reduce the rotating speed of cutting roller 140 or increase rotating speed of the forage pinch roll to fixing roller 120,
By reducing the radius of clean-up of driving pulley, while increase the radius of clean-up of driven pulley, that is, control the movable cone pulley of driving pulley
The acting device 530 on 520 sides makes two cone pulleys generate mutually from movement, while controls the start on movable 560 side of cone pulley of driven pulley
Device 570 moves toward one another the generation of two cone pulleys, the amount of movement of initiative taper wheel acting device 530 and driven cone pulley acting device 570
The stringent limitation of driven 540 constraint of fixed length of band meets the increased control requirement of ensilage staple fiber ppd.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modification is easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details and legend shown and described herein are not limited to novel.
