摘要: 随着城市建设规模的不断扩大和人们生活水平的不断提高，生活垃圾的运输与处理已成为人们不可忽视的卫生问题。高效的垃圾压缩运输是一种很好的解决方式，后压缩式垃圾车便是其中的一种常见结构形式。
本次设计课题来源于江苏悦达专用车有限公司，主要根据总体结构设计的要求对垃圾车车厢和排出机构液压系统进行了设计。车厢是垃圾车的重要部件之一，主要起装载、运输垃圾之用。运输过程中，不良机构容易造成二次污染。根据设计要求，确定了厢体形状和主要尺寸参数，重点考虑它的密封性；排出机构主要是用来排卸垃圾以及在垃圾装载时提供一定的背压力，使压缩后的垃圾密度均匀；在设计过程中，首先计算液压缸的外部载荷，然后根据结果计算出液压缸的主要参数，进而一步步确定液压系统中其他元件的参数。
通过设计，新型后压缩式垃圾车降低了工人劳动强度，有效地解决了垃圾运输过程中飘、洒、漏等问题，提高了运输效率，降低了运输成本，达到了环保需求，满足了设计要求。

The design of body in the garbage truck of rear loader compactor ——- YD5120SYZ
Abstract: With the continued expansion of the scale of urban construction and people’s living conditions continue to improve, it can’t be neglected that transporting and dealing with the living garbage become health problems. Efficient transport of compressed garbage is a good solution, which the garbage truck of rear loader compactor is a common structural form.
This design topic is from Jiangsu Yueda Special Vehicles Co.,Ltd. According to the total design requirements, it is mainly aims at the garbage truck compartment and vehicle discharge mechanism design. The compartment is one of the important parts mainly for the loading, transportation trash. In the transport process, bad structure is easy to result in secondary pollution. According to the design requirements, the compartment’s shape and the main size are designed. However main focus into its undergo. The discharge mechanism is mainly used to provide the certain backpressure which compresses the garbage density evenly. In the design process, the hydraulic tank external load is first calculated. Then the main hydraulic tank parameters are calculated. Thus the following parameters are defined.
Through the design, the new style garbage truck of rear loader compactor greatly reduces the labor intensity of the workers, effectively solve many problems, such as floating, spilling and leaking in the course of garbage transportation, which improves transport efficiency and reduces the cost of transportation. Thus the design can meet the environmental requirements and the design requirements.
