本发明的工作原理及使用流程:本玉米淀粉加工时自动化投料设备在实际使用时,首先将本设备稳定安装在待工作区域,接着启动液压缸102,通过液压缸102伸缩端驱动储料箱201与底座1相对位移,对支撑外桶202倾斜角度进行调整,接着将待投放的玉米粒置入投料箱325内部,随后手动启动螺旋给料机326,并给绕组216通电;
在启动螺旋给料机326后,其会将投料箱325内部玉米粒送入送料斗227内部,接着玉米粒会经投料管211从进料口210滚入对应的分离腔204内部,只有进料口210与投料管211对齐的相应的分离腔204才会滚入玉米粒,进而在玉米粒的自重作用下,会使滚动内筒203两侧重力不平衡,滚动内筒203会发生偏转,进而在滚动内筒203转动过程中,进料口210会依次与投料管211对齐,玉米粒会依次滚入各个分离腔204内部;
而随着滚动内筒203转动,当装有玉米粒的分离腔204位移到与下料斗212正上方后,其内部玉米粒会在自重作用下,穿过选料筛网206,经下料斗212落入中部的支撑外桶202上的接料斗213内部,而其余位置的分离腔204内部的玉米粒,则会在隔板232的阻隔作用下滞留在分离腔204内部,而落入接料斗213内部的玉米粒则会在自重下落入对应的分离腔204内部,中部的滚动内筒203也会在玉米粒的重力作用下偏转,进而依次使上、中、下三个滚动内筒203均在玉米粒的重力作用下偏转,而由于各个分离腔204在位移到最顶部时被送入玉米粒,在位移到最底部时其内部玉米粒经下料斗212排出,因此可使滚动内筒203两侧始终保持在重力失衡状态,进而驱使三个滚动内筒203均保持在转动状态;
在上述过程中,随着三个滚动内筒203的转动玉米粒会被不停筛选,在离心力作用下,玉米粒和金属颗粒等相对质量大的颗粒均会与玉米粒中夹带的轻质杂质分离,轻质杂质会穿过筛分板209落入连接座302内部,而在玉米粒穿过选料筛网206从电极板214间间隙落入下料斗212内部时,夹带的诸如金属颗粒等质量大、导电率高的杂质,则会在与电极板214接触时瞬间就获得了同性电荷,因而被排斥,无法穿过电极板214间间隙,滞留在分离腔204内部,并随分离腔204偏转到滚动内筒203另一侧,此时失去玉米粒的夹带阻隔,随着滚动内筒203的偏转,在自重作用下,一部分逐步从连通槽207穿过环形筛网208经导流槽205进入连接座302内部,另一部分直接穿过筛分板209进入连接座302内部;
在上述过程中玉米粒最终会经最底部下料斗212落入储料箱201内部,根据实际情况,在储料箱201和滚动内筒203内部填入适量玉米粒后,手动关停螺旋给料机326,并记录此时螺旋给料机326的启动时长;
而落入储料箱201内部的玉米粒,在导料板228的导向作用下,会始终保持向集料槽229汇聚的趋势,进而使玉米粒向螺旋上料机219的入料口汇聚,而在滚动内筒203转动的同时,其会带动传动轮220同步转动,传动轮220则会通过从动锥齿轮224驱动转杆223转动,转杆223则会通过驱动轮225和联动带226驱动螺旋上料机219的驱动轴转动,进而使螺旋上料机219将储料箱201内部的玉米粒送入送料斗227内部,随后该部分玉米粒会依次进入各个分离腔204内部,对该部分玉米粒进行循环筛选;
而在上述过程中给绕组216通电后,在绕组216通电和铁芯215配合作用下,会产生强力磁场,进而会在磁力作用下,通过导向块217和强力磁铁218相配合,利用磁性斥力,辅助玉米粒的重力作用,驱动滚动内筒203转动,在使滚动内筒203转动更稳定的同时,有效抵消玉米粒循环筛选过程中的摩擦力,使滚动内筒203的转动进一步偏离平衡状态;
在上述玉米粒循环筛选过程中,驱动轮225转动的同时,会通过联动带226驱动联动轮305转动,进而会带动导流扇304在导气腔303内部转动,进而会形成定向气流,一方面可在玉米粒循环筛选过程中牵引杂质更稳定的经连接座302进入输送筒301内部,另一方面则可利用定向气流对滚动内筒203的转动进行辅助性调控;
在辅助性调控工作中,定向气流会进入排气盒306内部,当气流压力足以克服压簧311弹力时,气流会驱动封堵板309上升,解除对排气口308的封堵,气流会经排气口308排出,而在封堵板309上升过程中,封堵板309上升会通过压簧311带动施压板312上升,施压板312会通过调压螺纹筒313驱动承压板315上升,承压板315会拖动触压开关316上升;
在触压开关316中只有欠压休眠开关受到挤压时,则说明此时气流压力为设定值,表明导流扇304转速即滚动内筒203的转速为设定值,此时欠压休眠开关会控制马达322休眠,在欠压休眠开关未受到挤压时,表明滚动内筒203的转速低于设定值,此时欠压休眠开关会控制马达322正转,马达322会通过减速齿轮323驱动从动齿轮320反转,进而通过卡座321驱动可调变阻器319的调节旋钮反转,调小其阻值,使流经绕组216的电流加大,提高磁场强度,驱使滚动内筒203加速转动,在欠压休眠开关和过载开关均受到触压时,表明滚动内筒203的转速高于设定值,此时过载开关会驱动马达322反转,降低磁场强度,驱使滚动内筒203减速;
而在上述过程中,在杂质进入输送筒301后,杂质会在自重作用下,经导流板331导向后,落到阻流座332,阻流座332则会在其重力作用下下沉,杂质会从导流板331和阻流座332穿过,并顺着输送筒301落入废料箱339内部,而阻流座332下沉,则会带动其底部触控开关333同步下沉,最终触控开关333会与套筒334抵接,在对玉米粒的循环筛选过程中,当玉米粒中还有杂质时,杂质会源源不断的落到阻流座332上,进而会使触控开关333始终与套筒334抵接,而在玉米粒中无杂质时,失去杂质的抵压,阻流座332会在承重弹簧336弹力作用下复位重新与导流板331抵接,触控开关333会脱离套筒334,在触控开关333连续不受抵压三十秒后,触控开关333会给时间继电器327通电,排料时间继电器会控制螺旋送料机324进行排料,并在排料完成后通过加料时间继电器控制螺旋给料机326将投料箱325内部玉米粒送入送料斗227进行新一轮选料工作;
在上述过程中,通过转动调节筒307,可利用连接杆314驱动调压螺纹筒313同步转动,对调压螺纹筒313总长度进行调控,改变压簧311的原始压缩量,进而对气力压力标准值进行设定,可根据实际况控制滚动内筒203转速,通过转动驱动杆328可对触控开关333和套筒334间的间距进行调控,进而控制给排料工作的调控灵敏度,对除杂质量和效率进行协调,通过时间继电器327可根据初始加料时长对给排料时长进行调控,提高投料稳定性。
