影响碎石撒布车精度的原因

来源:https://www.sddhfjx.com/ 日期:2022-01-10
撒布车零部件的制造与装配精度的影响
Influence of manufacturing and assembly accuracy of Spreader Parts
1、零部件制造与装配精度较低,会影响碎石撒布精度。由于碎石撒布车的料斗、布料滚筒、布料板等多用薄钢板经切割、折弯等工序后再焊接而制成的,焊接变形较大,制造与装配精度较低。当布料滚筒的圆度或圆柱度误差过大时,会导致抛撒碎石料的撒布量不均匀;当焊接料门限位块的位置误差过大时,会造成每个料门开度不一致,致使碎石撒布量不均匀;当布料滚筒的轴线与下料口下沿安装不平行,也会使得沿轴线方向的碎石料堆积量不等,当布料滚筒转动时带下的碎石流量也会有差异,致使碎石撒布量不均匀,而影响碎石撒布精度。
1. The manufacturing and assembly accuracy of parts is low, which will affect the gravel distribution accuracy. Because the hopper, distribution drum and distribution plate of the gravel spreader are mostly made of thin steel plate after cutting, bending and other processes, the welding deformation is large and the manufacturing and assembly accuracy is low. When the roundness or cylindricity error of the distribution drum is too large, it will lead to uneven distribution of crushed stones; When the position error of welding material threshold block is too large, the opening of each material door will be inconsistent, resulting in uneven distribution of gravel; When the axis of the distribution drum is not parallel to the lower edge of the blanking opening, the gravel accumulation along the axis will be different. When the distribution drum rotates, the gravel flow under the belt will also be different, resulting in uneven gravel distribution and affecting the gravel distribution accuracy.

2、碎石流过的撒布车表面的光滑性,也会影响碎石撒布精度。当料斗底板表面不光滑,会使碎石流动的随机性增大、撒布量会产生波动性的变化,也可能造成碎石撒布不均匀。
2. The smoothness of the surface of the spreader through which the gravel flows will also affect the gravel distribution accuracy. When the surface of the hopper bottom plate is not smooth, the randomness of gravel flow will increase, the distribution amount will fluctuate, and the uneven distribution of gravel may also be caused.

3、导料槽表面要求应无隆起的焊缝、无凸台、无凹槽等,并且所有拼接处及折弯处应做光滑处理。否则,易阻滞碎石的流动,碎石流动不畅,就会影响撒布精度。
3. The surface of the guide chute shall be free of raised welds, bosses, grooves, etc., and all splices and bends shall be smooth. Otherwise, it is easy to block the flow of gravel, and the poor flow of gravel will affect the distribution accuracy.
碎石料的物性、粒径,及在路面上的弹跳状况的影响
The influence of physical properties, particle size and bouncing condition of crushed stone on the pavement
碎石料的物性差异大、粒径不均匀时,使得每个料门下落的碎石量不同;同时,碎石落地后会弹起,形成碎石飞溅,导致碎石撒布均匀性变差;等等,都会影响撒布精度,但其影响远没有前面诸因素的影响显著。
When the physical properties of crushed stone vary greatly and the particle size is uneven, the amount of crushed stone falling from each material gate is different; At the same time, the gravel will bounce up after falling to the ground, forming gravel splash, resulting in poor gravel distribution uniformity; And so on, will affect the distribution accuracy, but its influence is far less significant than that of the previous factors.
