(1)撒布方法比较。

(1) Comparison of spreading methods.

人工撒布需满布满撒全幅撒布；机械撒布为电脑智能控制，且撒布宽度可在0.5m~4m范围内任意调节。

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)撒布均匀程度比较。

(2) The uniformity of spreading is relatively high.

人工撒布为人工铁锹撒布，撒布不均匀的情况时有发生；机械撒布为电脑精确控制，其撒布量不会因为车速快慢而改变，撒布车输料螺旋与拨料辊均可控制转速，输料与计量准确性高，且拨料辊在撒布水泥落地前再进行“散打”，可保证撒布效果更均匀。

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)撒布材料损耗情况比较。

(3) Comparison of material loss during spreading.

人工撒布时水泥实际控制剂量要较理论掺加量增加1%，而用设备撒布时掺量增加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)撒布时间比较。

(4) The spreading time is relatively long.

人工撒布水泥需人工提前打方格网且水泥需要人工装卸、摆放、拆包及撒布，费时费力；机械撒布为机械化作业，整个工作过程可由驾驶司机一人操作，机械化程度高，省时省力。

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)环境保护比较。

(5) Comparison of environmental protection.

人工撒布受天气及人力影响大，易出现扬尘，污染环境；机械撒布配备有抑尘罩，且配有脉冲式除尘系统，在撒布过程中可避免扬尘，环境污染小。

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.
