在北京十二国农机展览会上,法国尼古拉斯公司展出了一种碎石机,引起了人们的兴趣.这种碎石机为拖拉机配套,可以在田间直接把大石块粉碎成细小石块.它是土石山区平整土地、改良土壤的一种良好机型. 长期以来,乱石限制了可耕地的扩大,并造成了农作物的歉收.在耕作和收割时,由于田间存在乱石,常使犁铧折断、刀片打坏.在播种、施肥、洒药时,使种子、肥料、农药分布不均匀,影响作物的生长.为了清除田间石块,有些国家采用捡石机,把田间的石块收集起来,推到田间以外的地方,这种方法生产效率低,而且占用土地.采用碎石机,可以直接在田间碎石,有利于机械化工作,不减少土层厚度,不占用土地,不影响作物的生长. 碎石机不仅用于农田碎石,而且也可用于修筑公路中的碎石铺路.在更换不同型式的锤片后,还可用来清除灌木丛和打碎树枝,为开荒造田和拖拉机行驶 At the 12th Agricultural Machinery Exhibition in Beijing, France, Nicholas company exhibited a crusher, aroused people’s interest.This crusher for tractors, can be directly in the field to crush the boulders into small stones It is a good model for flattening and improving soils in mountainous and mountainous areas, which have for a long time limited the expansion of arable land and resulted in the crop failure. In the field of cultivation and harvesting, In the sowing, fertilizing, sprinkling medicine, the seeds, fertilizers, pesticides unevenly distributed, affecting the growth of crops.In order to clear the field of stone, some countries use stone picker, the collection of stone in the field Up and pushed to the field outside the field, this method is inefficient and occupies the land.Using the stone crusher, can directly gravel in the field, is conducive to mechanization, does not reduce the thickness of the soil, does not occupy the land, does not affect the crops The crusher is used not only for agricultural gravel but also for building gravel roads in the highways that can also be used to clear out bushes and break up branches after changing the type of hammer, Travel
