摘　　要：为了解决蛋鸡舍笼网上沉积的粉尘、粪污、羽毛杂物而引发鸡群体性呼吸道疾病,以及传统人工清理方法较难完全清除笼网上沉积的粉尘、粪污、羽毛杂物的问题,试验设计了一种蛋鸡笼网清扫装置,该装置主要由终端清扫装置、伸缩装置、升降装置和行进装置组成;对简化后的球形刷模型进行有限元分析和单因素试验,求得清扫力大且不伤害笼网镀层下的直流电机转速范围;通过单因素试验确定清扫装置行进速度范围,以行进速度、刷毛长度、直流电机转速为试验因素,以粉尘、粪污、羽毛清扫效率为评价指标,进行三因素三水平正交试验,分析出蛋鸡笼网清扫装置的最佳工作参数。结果表明:直流电机转速和装置行进速度对粉尘、粪污、羽毛清扫效率有极显著影响(P<0.01),刷毛长度只对羽毛清扫效率有极显著影响(P<0.01),该装置最佳工作参数为直流电机转速600 r/min、行进速度0.4 m/s、刷毛长度4 cm,装置对粉尘、粪污、羽毛的清扫效率分别为94.67%、89.98%、98.00%。说明该蛋鸡笼网清扫装置可有效地清扫鸡笼网上附着的杂物。In order to solve the problem that dust,manure,feathers and other debris deposited on the cage net of laying hens always cause the spread of collective respiratory diseases and other diseases,and the traditional manual cleaning method is difficult to completely remove,a chicken cage cleaning device was designed.The device is mainly composed of terminal cleaning device,telescopic device,lifting device and traveling device.The simplified model of the sweeping brush was subjected to finite element analysis and single factor test.The range of motor speed was obtained under the condition that the cleaning force was large and the coating of cage mesh was not damaged.The traveling speed range was determined by single factor test.Then,a three-factor and three-level orthogonal test was conducted with travel speed,brush length and DC motor speed as test factors,dust,fecal contamination and feather cleaning rates as evaluation indicators,in order to analyze the optimal working parameters of the chicken cage net cleaning device.The results showed that the motor speed and travel speed had significant influence on the cleaning effect of dust,feces and feathers(P<0.01),while the bristle length only had significant influence on the cleaning effect(P<0.01).The best working parameters of the device were DC motor speed of 600 r/min,device travel speed of 0.4 m/s and brush hair length of 4 cm.At this time,the cleaning rate of device for dust,faces,and feather was 94.67%,89.98%,and 98.00%,respectively.The device can effectively clean the debris attached to the chicken cage net.
