一种草原修复喷播机器人的设计(含CAD零件装配图,PROE三维图)(论文说明书13000字,CAD图6张,PROE三维图)
摘要
我国在草原荒漠化治理上一直在努力，对于草原荒漠化的对抗手段从人工上升到了机械设备。但是由于近几年的温室效应与内陆干旱，对于新疆等内陆地带，干旱缺水仍然是该地区的心头之患。对于荒漠化的治理，需要很大的人力成本和经济成本，而且需要常年定时定期维护。所以，这就需要有一种新的方式来对荒漠化进行治理。
本文设计的是一种全新的治理方法，本文所设计的机械是一种将草籽混合土壤与营养液可以混合喷射在远处草坡上的机械，叫做喷播机。这种机械设备的种植效率极高，在混合液中不光可以增加土壤与水分，还可以增加其他营养剂或者保湿剂等材质。这样喷出覆盖土地表面的草籽可以快速发芽，而且可以大范围的覆盖地面。免去人工较慢且工作量大的手工劳动。
本文主要设计的是机械设备的几大部分。分别为提供动力的电机和输送泵的选型和计算，还有传动部分的齿轮和轴等机构的计算与校核。还有对设备外形的设计与优化。本文利用二维和三维软件，可以有效、合理的对机械结构进行布置与设计。使得设计成果更为贴近市场。

ABSTRACT
China has been making efforts in grassland desertification control, and the means of combating grassland desertification have increased from manual labor to mechanical equipment. However, due to the greenhouse effect and inland drought in recent years, drought and water scarcity remain a major concern for inland regions such as Xinjiang. The control of desertification requires significant human and economic costs, and requires regular maintenance throughout the year. So, this requires a new approach to combating desertification.
The design of this article is a brand new governance method. The machinery designed in this article is a machine that can mix grass seeds with soil and nutrient solution and spray them on distant grass slopes, called a sprayer. The planting efficiency of this kind of mechanical equipment is extremely high. In the mixed solution, not only can the soil and water be increased, but also other nutrients or humectant and other materials can be added. This way, spraying grass seeds that cover the surface of the land can quickly sprout and cover the ground on a large scale. Eliminating manual labor that is slow and requires a lot of effort.
This article mainly designs several major parts of mechanical equipment. The selection and calculation of the motor and delivery pump that provide power, as well as the calculation and verification of the gears and shafts in the transmission part. There is also the design and optimization of equipment appearance. This article utilizes two-dimensional and three-dimensional software to effectively and reasonably arrange and design mechanical structures. Make the design results closer to the market.
Keywords: Grass seed sprayer machinery
