一、前言以往,国内网上平养肉鸡和笼养蛋鸡舍采用的清粪机有两种型式,一是自走式(也叫行车式)清粪机,二是牵引式清粪机。两者相比,自走式清粪机结构较复杂,对土建要求高,造价也高,且使用可靠性和安全性都存在问题。牵引式清粪机具有结构简单,对土建要求较低,造价低等优点;但也存在牵引钢丝绳使用寿命短 I. Foreword In the past, there were two types of manure clearing machines used in domestic flat broilers and cage laying hens. One is self-propelled (also called driving style) manure cleaner and the other is towed manure cleaner. Compared with the two, self-propelled cleaning dung machine structure is more complex, demanding on the civil engineering, high cost, and the use of reliability and safety problems. Tractor-type manure cleaner has the advantages of simple structure, low requirements on civil engineering, low cost and the like; however, there is also a short service life of the traction wire rope
