摘   要

     混凝土噴射機是利用壓縮空氣將混凝土沿管道連續輸送，并噴射到施工面上去的機械。分干式噴射機和濕式噴射機兩類，前者由氣力輸送干拌合料，在噴嘴處與壓力水混合后噴出；后者由氣力或混凝土泵輸送混凝土混合物經噴嘴噴出。廣泛用于地下工程、井巷、隧道、涵洞等的襯砌施工
螺旋式混凝土噴射機由螺旋喂料器將料斗卸下的干拌合料均勻地推送至吹送室，罐內裝攪拌好的混凝土。然后由螺旋喂料器空心軸和吹送管引入的壓縮空氣將干拌合料沿輸送管吹送至噴嘴。
螺旋式濕噴機特點：
(1) 結構螺旋式噴射機由傳動機構、料斗、機體、行走裝置、輸送軟管和噴槍組成。
(2) 優點螺旋式噴射機具有體積小、重量輕、結構簡單、上料點低、操作方便、出料均勻等優點。
(3) 缺點螺旋式噴射機粉塵濃度大、螺旋葉片磨損快, 需經常更換易損件。
本論文首先概括性地介紹了混凝土噴射機的發展歷史、工作原理，并分析了現有機型的優缺點，接著確定本次設計的機型。其次結合任務書的參數設計三級圓柱直齒減速器、輸料管、旋轉體等一些主要的部件，對部分要求比較高的零件進行強度校核。

關鍵詞：噴射機； 錨噴支護； 減速器。

ABSTRACT

Shotcrete Machine is the use of compressed air jet will be along the pipeline for transportation of concrete and blasting to the surface to the construction machinery. The dry and wet jet two types of jet aircraft, conveying gas from the former dry mixing materials, in the nozzle and pressure mixture of water emitted from the latter by the gas or to transport concrete pump nozzle emitted by the concrete mixture. Widely used in underground engineering, Roadway, tunnels, culverts, such as the lining construction.
   Jets from the spiral concrete spiral feed-hopper to discharge dry evenly mixing materials sent to the push Chuisong room, the tank with a good mixing of concrete. Feeding then spiral-Chuisong hollow shaft and the introduction of the compressed air will dry mixing materials along the pipeline blown sent to the nozzle.
   Spiral wet spraying machine features:
(1) spiral structure of the jet drive, hopper, body, walking devices, transmission of the hose and spray gun. (2) advantages of spiral jet with small size, light weight, simple structure, the low point on the material, easy to operate, the advantages of a uniform material. (3) shortcomings spiral jet dust concentration, spiral leaves and wear quickly, often need to replace wearing parts.
   This paper first general introduction to the history of the development of concrete Jets, principle and analysis of the advantages and disadvantages of the current models, and then determine the design of this model. This was followed by the combined task of the design parameters of three cylindrical straight teeth reducer, the loser of the material, such as rotation of some of the majorcomponents of some parts of the relatively high demand for strength checking.
