Description

真空吸尘车独立式强力吸嘴 技术领域
本发明涉及路面清洁车技术领域，特别是涉及一种真空吸尘车独立式强力吸嘴。
背景技术
吸尘车(或扫路车)是常用的环卫设备，其可以清洁路面，广泛应用于公路、公园、市政等路面清扫。现有的吸尘车一般是先利用扫地机构将垃圾聚集在一起，然后利用真空负压将垃圾抽吸至车载垃圾箱中。
其存在如下缺陷：1、清洁区域小，其清洁区域受限于扫地机构覆盖的区域，由于扫地机构一般比较小，导致其清洁区域小，只能清洁车轮两侧的路面；2、工作效率低，由于其需要先扫地聚拢垃圾，因此车速较低，一般低于10km/h，无法快速清洁路面；3、清洁不干净，由于路面不是光滑，而是有无数微小的缝隙，灰尘落在缝隙中无法扫起，导致清洁不干净，尤其是干式扫地车(不洒水)扫地时容易将灰尘扬起，对较大的垃圾，如小石头、运输车撒漏的垃圾等难以清理干净。
发明内容
本发明的目的在于针对现有技术的不足，而提供一种真空吸尘车独立式强力吸嘴，其结构科学，可以横向布置在吸尘车上，将路面的各种垃圾用强力负压吸起，清洁速度快，清洁效果好。

优选的，所述吸气管向吸尘车车尾倾斜。
优选的，所述吸气管向汽车中线方向倾斜。
优选的，所述吸嘴主体的前后两侧设置有与地面接触的支撑轮，所述支撑轮的的底端与所述吸尘口之间留有间隙。
优选的，所述负压吸腔从前向后宽度逐渐减小。
优选的，所述负压吸腔从下向上横截面积逐渐减小。
优选的，所述平铲的前端设置有向下倾斜的导板。
本发明的有益效果是：一种真空吸尘车独立式强力吸嘴，其包括吸嘴主体，所述吸嘴主体包括沿吸尘车左右方向并列布置的若干个吸嘴单元，所述吸嘴单元包括负压吸腔，所述负压吸腔的底部设置有平铲，所述负压吸腔的前侧设置有向下收口的前挡板，所述前挡板的底部与所述平铲的前端之间设置有吸尘口，所述负压吸腔的顶部设置有向上延伸的吸气管，相邻的所述吸嘴单元之间通过隔板隔离，本发明结构科学，可以横向布置在吸尘车上，将路面的各种垃圾吸起，各个吸嘴单元独立，其下方的吸力非常强劲，可以快速清洁路面，不仅清洁的区域宽，而且可以将灰尘、石头等都吸起，清洁效果好。

具体实施方式
下面结合附图和具体实施例对本发明作进一步详细的说明，并不是把本发明的实施 范围限制于此。
如图1-图4所示，本实施例的真空吸尘车独立式强力吸嘴，包括吸嘴主体，所述吸嘴主体包括沿吸尘车左右方向并列布置的若干个吸嘴单元1，所述吸嘴单元1包括负压吸腔2，所述负压吸腔2的底部设置有平铲21，所述负压吸腔2的前侧设置有向下收口的前挡板22，所述前挡板22的底部与所述平铲21的前端之间设置有吸尘口23，所述负压吸腔2的顶部设置有向上延伸的吸气管3，相邻的所述吸嘴单元1之间通过隔板4隔离。本发明结构科学，其利用平铲21、前挡板22、隔板4等围成负压吸腔2，负压吸腔2仅在吸气管3、吸尘口23两处开口，当使用风机抽吸时，在吸尘口23形成强力的负压，可以将各种垃圾吸起，送入车载垃圾箱内。该并列布置的吸嘴单元1将需要清洁的整个路面分成一个个较小的区域，抽吸时仅对该区域进行抽吸，使得吸力集中，吸力较强，并且可以根据车宽、车道宽度合理布置吸嘴单元1，使得在清洁区域内不留死角。该方案的平铲21并不解除地面，但是其与地面距离较近，大致平行于地面，容易将包括石头在内的路面垃圾吸起至平铲21上，然后通过吸气管3进入车载垃圾箱。
进一步的，所述吸嘴单元1为6～15个，所述吸嘴主体总长度等于或大于吸尘车的宽度，使得吸尘车整个行驶范围内都可以进行清洁，清洁区域大。尤其是吸嘴主体的两端可以伸出车身外，加大了清洁区域，位于吸尘车侧面车身处的所述吸嘴单元1与内侧相邻的所述吸嘴单元1通过铰链连接，所述吸嘴主体设置有驱动吸尘车侧面车身外的所述吸嘴单元1向上转动的拉杆(图中没有画出)，不使用时可以将车身外的吸嘴单元1收起，避免碰撞。
进一步的，所述吸气管3向吸尘车车尾倾斜，由于吸尘口23在前侧，吸尘车行驶时，垃圾相对吸尘车向后运动，将吸气管3向车尾方向倾斜，可以顺应其运动方向，更容易收集垃圾。
进一步的，所述吸气管3向汽车中线方向倾斜，由于吸嘴主体长度长度可以大于车身宽度，将吸气管3向汽车中线方向倾斜，便于将与吸气管3对接的装置隐藏在车身宽度之内。
进一步的，所述吸嘴主体的前后两侧设置有与地面接触的支撑轮5，所述支撑轮5的的底端与所述吸尘口23之间留有间隙，该支撑轮5可以抬高吸嘴主体，使得可以从上 方吸取垃圾，还可以避免吸嘴主体撞击地面。尤其是路面不平时，其可以对吸嘴主体起到保护作用。
进一步的，所述负压吸腔2从前向后宽度逐渐减小，所述负压吸腔2从下向上横截面积逐渐减小，通过这两点可以逐渐收缩负压吸腔2，使得垃圾更容易通过吸气管3吸走，避免堵塞在负压吸腔2内。
进一步的，所述平铲21的前端设置有向下倾斜的导板211，可以更好的收集垃圾。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
