一种双蜗轮单蜗杆传动联体筒式立轴搅拌机Double worm wheel single worm drive conjoined barrel type vertical shaft mixer 技术领域Technical field

本发明属于工程机械领域，特别涉及一种双蜗轮单蜗杆传动联体筒式立轴搅拌机。The invention belongs to the field of engineering machinery, and in particular relates to a double worm gear single worm drive conjoined barrel type vertical shaft mixer.

背景技术Background technique

混凝土搅拌机在工程机械领域应用广泛，其主要是一种搅拌设备，把事先按要求比例配比好的各种集料按照一定顺序加入搅拌桶内，加入水泥、水搅拌一定时间，搅拌成符合施工规范要求的混合料。搅拌设备在混凝土的生产过程中扮演着至关重要的作用，以此，搅拌设备的质量严重影响着混凝土的生产质量和生产效率。The concrete mixer is widely used in the field of construction machinery. It is mainly a kind of mixing equipment. The various aggregates that are pre-proportioned according to the required ratio are added to the mixing tank in a certain order. Cement and water are added for a certain period of time, and the mixture is mixed to meet the construction. Mixtures required by the specification. Mixing equipment plays a vital role in the production process of concrete. In this way, the quality of mixing equipment seriously affects the production quality and production efficiency of concrete.

现在普遍使用的混凝土搅拌机多为卧轴形式，轴端密封的问题一直无法有效地解决，当搅拌粘性大的混合料时卸料口存在粘结堵塞无法正常卸料的问题。而现有的立式混凝土搅拌机机型多为单立轴，搅拌效率低、搅拌时间长，仅适用于混凝土预制件的生产。常见的双立轴机型传动装置结构复杂、占用空间大、传动效果不稳定，卸料也比较费力，搅拌臂的连接结构无法满足搅拌大体积混合料的刚度要求。At present, most commonly used concrete mixers are in the form of horizontal shafts, and the problem of shaft end seals has not been effectively solved. When mixing viscous mixtures, there is a problem that the discharge port is stuck and blocked and cannot be discharged normally. The existing vertical concrete mixer models are mostly single vertical shafts, which have low mixing efficiency and long mixing time, and are only suitable for the production of precast concrete parts. The transmission device of the common double-vertical shaft type has a complicated structure, a large space occupation, an unstable transmission effect, and a relatively laborious unloading process. The connection structure of the mixing arm cannot meet the rigidity requirements of mixing large-volume mixed materials.
