自由下落類碎石撒布車，其碎石料的下落和撒布主要依靠其自身的重力作用；在碎石料的撒布過程中，其下落和撒布過程受隨機(jī)性因素的影響很顯著，撒布過程的可控性差；同時(shí)，其對撒布精度的影響因素較多，影響關(guān)系較復(fù)雜、不確定性較大，進(jìn)而導(dǎo)致碎石料的撒布精度難以有效控制。而且，對碎石料粒徑的大小和一致性均要求高，否則易造成布料不均勻現(xiàn)象，施工作業(yè)質(zhì)量也較差。正是由于以上這些原因，才導(dǎo)致碎石撒布時(shí)容易出現(xiàn)“麥垅狀條紋”的情況，作業(yè)質(zhì)量較差。
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.
皮帶輸送式螺旋撒布車，其碎石料的輸送和撒布都有具體的機(jī)構(gòu)和驅(qū)動力，對撒布精度的影響因素較少，影響關(guān)系的確定性較好，其撒布過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，其最大撒布寬度沒有限制，且對碎石料粒徑的大小和一致性要求不高；施工作業(yè)質(zhì)量好。也正是由于以上這些原因，才導(dǎo)致碎石撒布時(shí)常常出現(xiàn)碎石撒布均勻性好、施工作業(yè)質(zhì)量較好的效果。
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.
兩類不同的碎石撒布車結(jié)構(gòu)和工作特點(diǎn)及其對撒布精度的影響的分析與比較，可得出如下結(jié)論：
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）將目前主流車型上使用的碎石撒布車歸納為自由下落類和機(jī)構(gòu)驅(qū)動類等兩類；
(1) The gravel spreader used in the current mainstream models is divided into two categories: free falling type and mechanism driven type;
（2）自由下落類碎石撒布車，其碎石料的下落和撒布主要依靠其自身的重力作用，在碎石料在撒布過程中，下落和撒布過程受隨機(jī)性因素的影響很顯著，對撒布精度的影響因素較多，影響關(guān)系較復(fù)雜、不確定性較大，碎石料的撒布精度難以有效控制。
(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）皮帶輸送式螺旋撒布車，其碎石料的輸送和撒布都有具體的機(jī)構(gòu)和驅(qū)動力，對撒布精度的影響因素較少，影響關(guān)系的確定性較好，其撒布過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）機(jī)構(gòu)驅(qū)動類碎石撒布車比自由下落類的可控性更好、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.
