(1)撒布方法比較。

(1) Comparison of spreading methods.

人工撒布需滿布滿撒全幅撒布；機械撒布為電腦智能控制，且撒布寬度可在0.5m~4m范圍內任意調節。

Manual spreading requires full coverage and full width spreading; Mechanical spreading is controlled by computer intelligence, and the spreading width can be adjusted freely within the range of 0.5m~4m.

(2)撒布均勻程度比較。

(2) The uniformity of spreading is relatively high.

人工撒布為人工鐵鍬撒布，撒布不均勻的情況時有發生；機械撒布為電腦精確控制，其撒布量不會因為車速快慢而改變，撒布車輸料螺旋與撥料輥均可控制轉速，輸料與計量準確性高，且撥料輥在撒布水泥落地前再進行“散打”，可保證撒布效果更均勻。

Manual distribution refers to manual shovel distribution, and uneven distribution occurs occasionally; Mechanical spreading is precisely controlled by a computer, and its spreading amount will not change due to the speed of the vehicle. The feeding screw and feeding roller of the spreading vehicle can both control the speed, and the feeding and measuring accuracy is high. In addition, the feeding roller performs a "sanda" before spreading the cement to the ground, ensuring a more uniform spreading effect.

(3)撒布材料損耗情況比較。

(3) Comparison of material loss during spreading.

人工撒布時水泥實際控制劑量要較理論摻加量增加1%，而用設備撒布時摻量增加0.5%即可。

When manually spreading, the actual controlled dosage of cement should be increased by 1% compared to the theoretical dosage, while when using equipment for spreading, the dosage can be increased by 0.5%.

(4)撒布時間比較。

(4) The spreading time is relatively long.

人工撒布水泥需人工提前打方格網且水泥需要人工裝卸、擺放、拆包及撒布，費時費力；機械撒布為機械化作業，整個工作過程可由駕駛司機一人操作，機械化程度高，省時省力。

Manual spreading of cement requires pre grid laying and manual loading, unloading, placement, unpacking, and spreading, which is time-consuming and labor-intensive; Mechanical spreading is a mechanized operation, and the entire process can be operated by the driver alone, with a high degree of mechanization and saving time and effort.

(5)環境保護比較。

(5) Comparison of environmental protection.

人工撒布受天氣及人力影響大，易出現揚塵，污染環境；機械撒布配備有抑塵罩，且配有脈沖式除塵系統，在撒布過程中可避免揚塵，環境污染小。

Artificial spreading is greatly affected by weather and manpower, and is prone to dust and environmental pollution; Mechanical spreading is equipped with a dust suppression hood and a pulse type dust removal system, which can avoid dust during the spreading process and minimize environmental pollution.
