Description
技术领域technical field
本实用新型涉及车辆冲洗设备技术领域,具体为一种市政施工用洗轮机。The utility model relates to the technical field of vehicle washing equipment, in particular to a wheel washing machine for municipal construction.
背景技术Background technique
洗轮机是一种专门用来清洁车辆轮胎和轮毂的设备,可以自动完成整个清洗过程,它主要由高压水枪、刷子、喷嘴、水泵等组成,能够有效地去除车辆表面的污垢、泥沙和油渍,现有的市政施工用洗轮机不便于对车轮上冲洗下来的砂子进行清理,在对砂子进行处理时一般是将砂子跟随污水一起排入市政管道,导致市政管道很容易被砂子堵塞,因此需要研制出一种便于对砂子进行清理的结构,进而能够避免砂子将市政管道堵塞,提升市政施工用洗轮机对砂子的清理效果。Wheel washing machine is a kind of equipment specially used to clean vehicle tires and wheel hubs. It can automatically complete the entire cleaning process. It is mainly composed of high-pressure water guns, brushes, nozzles, water pumps, etc., which can effectively remove dirt, sand and oil stains on the surface of vehicles. , the existing municipal construction wheel washing machine is inconvenient to clean the sand washed off the wheels. When the sand is processed, the sand is generally discharged into the municipal pipeline along with the sewage, causing the municipal pipeline to be easily blocked by sand. Therefore, it is necessary to A structure that is convenient for cleaning sand has been developed, which can prevent sand from clogging municipal pipelines and improve the sand cleaning effect of the municipal construction wheel washer.
现有的市政施工用洗轮机存在的缺陷是:The defective that existing municipal construction wheel washing machine exists is:
专利文件CN212579812U公开了一种市政施工用洗轮机,保护的权项“其结构包括两侧固定挡板、透水板、底座、水源接口、挡水区域调节装置,通过接通水源,操作冲洗槽喷洗装置,开始洗轮机对施工车辆的冲洗工作,通过使用人员根据施工车辆的车型大小,转动挡水区域调节装置,使得螺杆在螺杆活动槽内部卡合活动而横向移动,使得连接块横向移动,与连接块相连接的横向挡片被拉伸出来,转动横杆随着连接块移动,活动连接杆在底座边缘的滑槽里滑动,带动折叠连接杆展开,使得活动挡板展开,从而对部分区域边缘起到挡水作用,由使用人员自行调节遮挡面积,在水从透水板下方的冲洗槽网上喷的时候,将不必要冲洗的区域的水直接挡住,避免除了对施工车辆冲洗外的水资源的浪费”。Patent document CN212579812U discloses a washing machine for municipal construction. The protection claim "its structure includes fixed baffles on both sides, a permeable plate, a base, a water source interface, and a water retaining area adjustment device. By connecting the water source, the washing tank is operated to spray water. The washing device starts the washing work of the construction vehicle by the wheel washing machine. According to the size of the construction vehicle, the user rotates the water-retaining area adjustment device to make the screw engage and move laterally in the screw movable groove, so that the connecting block moves laterally. The transverse baffle connected to the connecting block is stretched out, the rotating bar moves with the connecting block, the movable connecting rod slides in the chute on the edge of the base, and the folding connecting rod is driven to expand, so that the movable baffle is unfolded, thereby The edge of the area plays the role of water blocking, and the user can adjust the blocking area by himself. When the water is sprayed from the flushing tank net under the permeable plate, the water in the unnecessary flushing area will be blocked directly, so as to avoid the water except for flushing the construction vehicles. waste of resources".
然而上述公开文献的市政施工用洗轮机主要考虑通过活动挡板来降低冲洗车辆时水资源的浪费的问题,没有考虑到市政施工用洗轮机不便于对车轮上冲洗下来的砂子进行清理,在对砂子进行处理时一般是将砂子跟随污水一起排入市政管道,导致市政管道很容易被砂子堵塞的问题。However, the municipal construction wheel washing machine of the above-mentioned published documents mainly considers the problem of reducing the waste of water resources when washing the vehicle through the movable baffle, and does not consider that the municipal construction wheel washing machine is not convenient for cleaning the sand washed off the wheels. When the sand is processed, the sand is generally discharged into the municipal pipeline along with the sewage, which leads to the problem that the municipal pipeline is easily blocked by the sand.
因此,有必要研究出一种便于对砂子进行清理的结构,进而能够避免砂子将市政管道堵塞,提升市政施工用洗轮机对砂子的清理效果。Therefore, it is necessary to develop a structure that is convenient for cleaning the sand, so as to prevent the sand from clogging the municipal pipeline and improve the sand cleaning effect of the municipal construction wheel washer.
