Embodiment
When maize straw passes through to decide, when moving pick device, because it is fixed, adjustable gaps between the moving pick device, when the maize straw load increases, move pick-up roller 16 in the moving pick-up roller device and decide to decide in the pick-up roller device extruding that pick-up roller 14 is subjected to maize straw, have separated trend, deciding pick-up roller 14 is installed on and decides on the pick-up roller device, be fixed on the moving device shell 1 of liter and decide the pick-up roller device, moving on can not occurrence positions, and moving pick-up roller 16 is installed on the moving pick-up roller device, moving pick-up roller setting position is variable, but specifically shift gears is because 8 rotations of moving pick-up roller device moving axle, its position of rotation has two extreme positions, one is when not loading, by the decision of the height of sleeve 20 and packing ring 21 both sums in Fig. 2, another is when limit load, when spring 23 is in limit compression position, freely change between these two positions is that power and the spring 23 that is subjected to move on the pick-up roller 16 in the moving pick-up roller device of maize straw extruding is subjected to force compresses, deformation takes place in spring 23, length changes, when the elastic force of power on the moving pick-up roller 16 and spring 23 generation deformation generations equates, the decision of spring 23 present positions.
Moving pick-up roller 16 is loaded on the moving axis 8, forms parts by moving axis bearing 9 and moving axis bearing block 7, and two ends are individually fixed on left moving axis spiral arm 4, the right moving axis spiral arm 17.On the left and right two moving axis spiral arms 4,17 swivel bearing 19 is housed; Left and right two braces 5 are installed on respectively on the left and right moving axis spiral arm 4,17, also are provided with sleeve 20, packing ring 21, bolt 6, spring 23, adjusting nut 24 on the left and right brace 5, hangers 22, and hangers 22 is installed on the elevator channel 1.Packing ring 21 is used for spacing, thickness and quantity by increase and decrease packing ring 21 are regulated spacing, spring 23 is in compressive state, the pressure size of coming regulating spring 23 by the position of adjusting adjusting nut 24, adjust the size that left and right two moving axis spiral arms 4,17 rotate up the required power that overcomes thereby reach, and during 4,17 rotations of left and right moving axis spiral arm, drive moving axis 8 and moving pick-up roller 16 to rotate, make pick-up roller 16 and the gap of deciding between 14 liang of rollers of pick-up roller changes.During work, because the amount of passing through to move pick-up roller 16 and decide the maize straw between the pick-up roller 14 is changing, so the gap between two rollers is changing at any time with the amount by stalk, by adjusting, the variable quantity in this gap is generally within 20mm, because stopping up can not appear when live load is very big in the variation in gap yet.
Before the use, should adjust the thickness and the quantity of packing ring 21, the distance between moving axis 8 and the dead axle 10 is controlled at about 85mm, adjust adjusting nut 24 and make spring 23 when the compression limit position, moving axis 8 and dead axle 10 spacings are about 105mm.
