本发明的核心是提供一种混凝土搅拌站， 该混凝土搅拌站不仅能够生 产混凝土， 而且还能够比较方便地生产较高质量的湿砂浆。
为了使本领域的技术人员更好地理解本发明的技术方案， 下面结合附 图和具体实施例对本发明作进一步的详细说明。
请参考图 2,图 2为本发明一种实施例中混凝土搅拌站的结构示意图。 在一种实施例中， 如图 2所示， 本发明所提供的混凝土搅拌站包括配 料站 1 , 且配料站 1设有骨料仓 11 ; 在此现有技术的基础上， 所述混凝土 搅拌站进一步设有与骨料仓 11配合的砂料薛分输送系统 2。
当生产混凝土时， 砂料筛分输送系统 2不工作， 采用装载机给配料站 1的骨料仓 11上料， 然后再根据前文背景技术所述的工作过程完成混凝土 的搅拌。
当生产湿砂浆时， 砂料筛分输送系统 2工作， 将湿砂浆所需要的粗砂 或者细砂进行薛分并输送进配料站 1相应的骨料仓 11中，此后的工作过程 与混凝土制造过程基本相同， 在此不再赘述。
在本发明中， 由于砂料筛分输送系统 2会对砂料进行筛分， 因而能够 保证湿砂浆的质量， 并且生产效率得到了提高。 由此可知， 本发明所提供 的混凝土搅拌站不仅能够生产混凝土， 而且还可以比较方便地生产较高质 量的湿砂浆。
请参考图 3 , 图 3为图 2中混凝土搅拌站的砂料筛分系统的结构示意 图。
需要说明的是，上述实施例对于砂料筛分输送系统 2的结构不作限制， 因而任意一种结构的装置， 只要能够实现对砂料的筛分和输送， 均在本发 明的保护范围之内。在此，可以设计砂料薛分输送系统 2的一种具体结构。
如图 3所示， 砂料筛分输送系统 2包括皮带机 21、 筛分机 22和分料 装置 23 , 薛分机 22设于皮带机 21的进料端， 分料装置 23设于皮带机 21 的出料端； 分料装置 23与骨料仓 11配合。
筛分机 22对砂料进行过滤和分级， 筛分出需要的砂料； 然后筛分出的 砂料落到皮带机 21的进料端， 皮带机 21运动， 将砂料运至出料端， 然后 进入分料装置 23中； 分料装置 23工作， 将砂料分入相应的骨料仓 11中， 比如， 如果砂料是粗砂， 分料装置 23便将粗砂分入骨料仓 11中的粗砂仓 中，如果砂料是细砂， 分料装置 23便将细砂分入骨料仓 11中的细砂仓中。
在该技术方案中， 砂料筛分输送系统 2包括筛分机 22, 因而能够保证 湿砂浆具有较高的质量； 此外， 砂料筛分输送系统 2还包括皮带机 21 , 因 而输送效率高， 从而保证了湿砂浆具有较高的生产效率； 最后， 该砂料筛 分输送系统 2还包括分料装置 23 ,从而使得生产不同的湿砂浆的转换过程 比较筒便。
请参考图 4、 图 5、 图 6和图 7, 图 4为图 3中砂料筛分系统的分料装 置的结构示意图； 图 5为图 4中分料装置的工作状态示意图； 图 6为图 5 中粗砂导料槽导通、 细砂导料槽关闭时的分料装置的工作状态示意图； 图 7为图 5中细砂导料槽导通、 粗砂导料槽关闭时的分料装置的工作状态示 意图。
在上述技术方案中， 可以对分料装置 23的结构作出具体设置。
具体地， 如图 4和图 5所示， 分料装置 23包括位于皮带机 21出料端 下方的进料斗 231 , 并且如图 5所示， 进料斗 231设有粗砂导料槽 232和 细砂导料槽 233。 同时， 与分料装置 23配合的骨料仓 11的数目为两个， 分别为粗砂仓和细砂仓。 在此基础上， 粗砂导料槽 232与所述粗砂仓可选 择地连通或者中断， 细砂导料槽 233与所述细砂仓可选择地连通或中断。
在该技术方案中，当需要用粗砂搅拌湿砂浆时，筛分机 22筛分出粗砂， 并通过皮带机 21将粗砂输送至分料装置 23的进料斗 231内， 此时粗砂导 料槽 232与粗砂仓连通， 关闭细砂导料槽 233 , 从而将粗砂输送进粗砂仓 中， 进而完成湿砂浆的搅拌。 当需要用细砂搅拌湿砂浆时， 筛分机 22筛分 出细砂， 并通过皮带机 21将细砂输送至分料装置 23的进料斗 231内， 此 时细砂导料槽 233与细砂仓连通， 关闭粗砂导料槽 232, 从而将细砂输送 进细砂仓中， 进而完成湿砂浆的搅拌。 显然， 该种技术方案非常方便地实 现了将不同的砂料输送至不同的骨料仓 11中， 并且生产效率比较高。
请参考图 5 , 为了比较方便地实现粗砂导料槽 232和细砂导料槽 233 的连通或关闭， 粗砂导料槽 232内可以设有可开启或者关闭的粗砂开关门 234, 并同时在细砂导料槽 233内设有可开启或者关闭的细砂开关门 235。
如图 6所示， 当需要用粗砂搅拌湿砂浆时， 打开粗砂开关门 234, 关 闭细砂开关门 235 , 通过粗砂导料槽 232连通进料斗 231和粗砂仓， 从而 将粗砂输进粗砂仓中； 如图 7所示， 当需要用细砂搅拌湿砂浆时， 打开细 砂开关门 235 , 关闭粗砂开关门 234, 通过细砂导料槽 233连通进料斗 231 和细砂仓， 从而将细砂输进细砂仓中。
需要说明的是， 上述技术方案对于如何实现粗砂开关门 234和细砂开 关门 235的开启或者关闭， 并没有作出限制， 因而任意一种结构， 只要能 够实现两个开关门的开启或者关闭， 均应该在本发明的保护范围之内。
对此， 可以设计一种实现门开启或者关闭的具体结构。 比如， 如图 4 所示，粗砂开关门 234通过第一门轴可旋转连接于粗砂导料槽 232的槽壁， 且所述第一门轴连接有驱动其旋转的第一气缸；进一步地，细砂开关门 235 通过第二门轴可旋转连接于细砂导料槽 233的槽壁， 且所述第二门轴连接 有驱动其旋转的第二气缸。 通过气缸 236的伸缩， 带动门轴 237的旋转， 并随之带动与门轴 237连接的粗砂开关门 234或细砂开关门 235旋转， 进 而实现开关门的开启或者关闭。 显然， 这种设计非常方便的实现了开关门 的开启或者关闭， 并且结构比较筒单， 制造成本较低。
需要说明的是， 图 4中所示的气缸 236、 门轴 237和开关门分别可以 具体是指上文所述第一气缸、 第一门轴和粗砂开关门， 或者可以具体是指 上文所述的第二气缸、 第二门轴和细砂开关门。 如图 4所示， 在上述任一种技术方案中， 砂料筛分输送系统 2进一步 设有固定支架 24, 该固定支架 24用于支撑分料装置 23。 进一步地， 如图 4所示， 分料装置 23设有外壳 238, 固定支架 24与该外壳 238连接， 从而 实现对分料装置 23的支撑功能。
此外， 在上述任一种技术方案中， 如图 3所示， 砂料筛分输送系统 2 的筛分机 22的设有出料口 221 , 该出料口 221位于皮带机 21进料端的上 方， 以便从出料口 221出来的砂料落入皮带机 21上。
最后， 以上对本发明所提供的一种混凝土搅拌站进行了详细介绍。 本 的说明只是用于帮助理解本发明的方法及其核心思想。 应当指出， 对于本 技术领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以对 本发明进行若干改进和修饰， 这些改进和修饰也落入本发明权利要求的保 护范围内。
