Spraying device for spraying anti-freezing agent

The spraying device comprises a bottom plate, a vertical plate is fixed to the upper end of the left side of the bottom plate, a connecting plate is arranged on the outer side of the vertical plate in a sliding mode, and a containing box is arranged at the upper end of the connecting plate. An air cylinder drives a connecting plate to move up and down, so that the connecting plate drives a sliding block to slide on the inner wall of a sliding groove, and it is guaranteed that the connecting plate drives a containing box to stably move up and down; an electric telescopic rod moves a right-angle block to a proper position, a water pump is started to introduce an anti-freezing agent into a water cavity, and then the anti-freezing agent is sprayed out through a liquid outlet spray head. 本实用新型公开了一种用于喷淋防冻剂的喷淋装置，包括底板，底板的左侧上端固定有立板，立板的外侧滑动设置有衔接板，衔接板的上端设置有盛放箱。气缸带动衔接板进行上下移动，使得衔接板带动滑块在滑槽内壁滑动，保证衔接板带动盛放箱进行稳定的上下移动；电动伸缩杆将直角块移动到合适的位置，打开水泵将防冻剂引入到水腔中，再通过出液喷头喷出。
