自由下落类碎石撒布车，其碎石料的下落和撒布主要依靠其自身的重力作用；在碎石料的撒布过程中，其下落和撒布过程受随机性因素的影响很显著，撒布过程的可控性差；同时，其对撒布精度的影响因素较多，影响关系较复杂、不确定性较大，进而导致碎石料的撒布精度难以有效控制。而且，对碎石料粒径的大小和一致性均要求高，否则易造成布料不均匀现象，施工作业质量也较差。正是由于以上这些原因，才导致碎石撒布时容易出现“麦垅状条纹”的情况，作业质量较差。
Free falling gravel spreader, the falling and distribution of gravel mainly depends on its own gravity; In the distribution process of crushed stone, its falling and distribution process are significantly affected by random factors, and the controllability of the distribution process is poor; At the same time, there are many factors affecting the distribution accuracy, the influence relationship is complex and uncertain, which makes it difficult to effectively control the distribution accuracy of crushed stone. Moreover, the size and consistency of gravel particle size are required to be high, otherwise it is easy to cause uneven distribution and poor construction quality. It is precisely for these reasons that "Wheat Ridge like stripes" are easy to appear during gravel distribution, and the operation quality is poor.
皮带输送式螺旋撒布车，其碎石料的输送和撒布都有具体的机构和驱动力，对撒布精度的影响因素较少，影响关系的确定性较好，其撒布过程和撒布精度的可控性好，可有效控制碎石料的撒布精度。而且，其最大撒布宽度没有限制，且对碎石料粒径的大小和一致性要求不高；施工作业质量好。也正是由于以上这些原因，才导致碎石撒布时常常出现碎石撒布均匀性好、施工作业质量较好的效果。
The belt conveying spiral spreader has specific mechanism and driving force for the transportation and distribution of crushed stone. It has few factors affecting the distribution accuracy, has good certainty of the influence relationship, and has good controllability of the distribution process and distribution accuracy, which can effectively control the distribution accuracy of crushed stone. Moreover, the maximum spreading width is not limited, and the requirements for the size and consistency of gravel particle size are not high; Good construction quality. It is precisely for these reasons that the effect of good gravel distribution uniformity and good construction quality often occurs during gravel distribution.
两类不同的碎石撒布车结构和工作特点及其对撒布精度的影响的分析与比较，可得出如下结论：
Based on the analysis and comparison of the structure and working characteristics of two different types of gravel spreaders and their influence on the spreading accuracy, the following conclusions can be drawn:
（1）将目前主流车型上使用的碎石撒布车归纳为自由下落类和机构驱动类等两类；
(1) The gravel spreader used in the current mainstream models is divided into two categories: free falling type and mechanism driven type;
（2）自由下落类碎石撒布车，其碎石料的下落和撒布主要依靠其自身的重力作用，在碎石料在撒布过程中，下落和撒布过程受随机性因素的影响很显著，对撒布精度的影响因素较多，影响关系较复杂、不确定性较大，碎石料的撒布精度难以有效控制。
(2) For free falling gravel spreader, the falling and distribution of gravel mainly depends on its own gravity. In the distribution process of gravel, the falling and distribution process are significantly affected by random factors. There are many factors affecting the distribution accuracy, complex influence relations and great uncertainty, and the distribution accuracy of gravel is difficult to be effectively controlled.
（3）皮带输送式螺旋撒布车，其碎石料的输送和撒布都有具体的机构和驱动力，对撒布精度的影响因素较少，影响关系的确定性较好，其撒布过程和撒布精度的可控性好，可有效控制碎石料的撒布精度。
(3) The belt conveying spiral spreader has specific mechanism and driving force for the transportation and distribution of crushed stone. It has few factors affecting the distribution accuracy, has good certainty of the influence relationship, and has good controllability of the distribution process and distribution accuracy, which can effectively control the distribution accuracy of crushed stone.
（4）机构驱动类碎石撒布车比自由下落类的可控性更好、碎石撒布精度更高。
(4) The mechanism driven gravel spreader has better controllability and higher gravel spreading accuracy than the free falling type.
