具体实施方式
下面结合附图所示的各实施方式对本发明进行详细说明，但应当说明的是，这些实施方式并非对本发明的限制，本领域普通技术人员根据这些实施方式所作的功能、方法、或者结构上的等效变换或替代，均属于本发明的保护范围之内。
参图1所示，本实施例提供了一种单立柱提升混合机，包括提升机构、滑块13及用于夹持混合容器16的回转叉架15，提升机构与滑块13连接，用于带动滑块13沿竖直方向滑动，回转叉架15与滑块13连接，用于在滑块13的带动下运动至预设位置；提升机构包括电动推杆5，电动推杆5内设 有螺杆副19，螺杆副19具有可自锁的螺纹，并可通过螺纹传动进行伸缩，螺杆副19的自由端连接有滑轮9，滑轮9套有提升带(提升带可以是链条10，也可以是其它提升带)，提升带的一端固定，另一端与滑块13连接。
本实施例提供的单立柱提升混合机，通过具有自锁功能的电动推杆进行提升，无需另设防坠装置，运行过程中不会对环境造成污染，且结构简单，提升方便，升程易于控制。
在本实施例中，立柱上设有由平行导轨18形成的滑槽，滑块13设有滚轮20，两组滚轮20设于滑槽中，并可在滑槽内滚动。通过滚轮及滑槽的设计，可以使滑块更加稳定地进行升降。
立柱2通过螺钉或焊接与底座1装配在一起，立柱2前侧是导轨部分，滑块13在导轨内能上下滑动，立柱2后侧是电动推杆安装部分，电动推杆5与铰轴支座3相连，支座3用螺钉安装在立柱2后侧的安装板上。
电动推杆5的动力侧与电机21(配有减速器)连接，另一端与滑轮9相连接，滑轮9是双滑轮结构；立柱2后侧装有链条连接板8，两条链条10对称分布在与电动推杆上5两滑轮上，一端通过连接件固定在链条连接板8上，另一端固定在滑块13上，滑块13与传动箱14螺钉固定连接，传动箱14内装有电机减速器，通过连接法兰与回转叉架15连接，回转叉架15上装有两叉杆，用来夹持混合容器16，11为顶部固定装置。
参图1及图2所示，回转叉架15使混合容器16与其对称轴线成一夹角30度。另外，该混合机配有电器控制台。工作时，叉杆位于基位，将混合容器16推入回转叉架15内，混合容器16的两叉管分别与回转叉架15的两叉杆套合，直到叉管壁内锥与叉杆外锥相接触。在两叉杆上加上带外锥的垫圈，并用锁紧螺母17锁紧混合容器16，开动控制台，控制电动推杆5上的电机按规定方向转动，通过减速器的变速，电动推杆5内的螺杆副19带动滑轮9上升的同时链条也带动滑块13上升，电动推杆5的行程为滑块行程的1/2，使夹持有混合容器16的回转叉架15上升到达混合位，限位开关7给PLC(控 制台)信号设备停止上升，启动混合程序，按程序设定的混合参数混合，达到混合时间，设备停止混合，并完成定位(使混合容器16的脚轮向下)，再次提升至设备的分料位，此时可用其它容器分装混合容器内的物料，亦可以不上升到分料位，直接下降到基位。随后，松开锁紧螺母17，取出垫圈，往外拉出混合容器16。
本实施例提供的单立柱提升混合机具有如下技术效果：
1、电动推杆通过螺纹传动，根据实际速度要求最佳提升速度在20-30m/s，电动推杆的速度约在12.5m/s，螺杆副采用具有自锁性能的Tr螺纹(梯形螺纹)，不需要另设防坠装置，具有全程防坠性能，可靠性高。
2、通过采用电动推杆进行提升，彻底解决了液压油的环境污染问题。
3、电动推杆的提升速度可按实际需求设定，可替代液压油泵用节流阀来调整速度的方案。
4、通过滑轮机构，使螺杆行程仅为滑块行程的一半，降低了设备的加工难度，有利于缩小产品的结构尺寸。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。
