As shown in Figure 1, a hand-push small road deicing vehicle mainly includes a deicing device 1, a deicing roller lifting mechanism 2, a frame assembly 3, an engine and a transmission device 4, a deicing device Ice truck traveling device 5, crushed ice cleaning plate 6 and other components.

As shown in Figures 1 and 2, the core component of the de-icing device 1 is a wedge-shaped de-icing blade 1-1, and its material is selected as a low-alloy high-strength structural steel 16Mn with strong compressive resistance at low temperature and good welding properties. The front and rear angles are set to 40° and 28°, respectively. According to the length of the deicing roller and the requirements for deicing efficiency, the blade length of the wedge-shaped deicer is set to 42 mm. The wedge-shaped de-icer 1-1 is fixed on the de-icing roller 1-2 by welding. The axial arrangement and quantity of the wedge-shaped de-icer 1-1 on the de-icing roller 1-2 significantly affect the deicing. The deicing effect of the rollers; under the premise of a certain travel speed during the road ice removal operation, if the number of wedge-shaped deicers 1-1 in the axial arrangement is too large, the front row of wedge-shaped deicers 1-1 cannot penetrate into the ice layer. When the task of crushing ice is completed, the wedge-shaped deicers 1-1 in the rear row have also touched the ice surface, which affects the ice removal effect and causes energy waste; After a long period of time after the ice blade 1-1 breaks the ice, the rear wedge-shaped de-icer 1-1 removes the road ice layer and starts the de-icing operation, thus causing the road ice layer to be removed incompletely and reducing the de-icing effect; therefore, wedge-shaped de-icers are installed. 1-1 The number of rows on the de-icing roller 1-2 is 12, that is, the arc between the two rows of wedge-shaped de-icing blades 1-1 is 30°, and each row is welded on the de-icing roller 1-2. 7 A wedge-shaped deicer 1-1. The wedge-shaped deicer 1-1 is fixed on the deicing roller 1-2 by welding. If the fixed angle is too large, the risk of the wedge-shaped deicer 1-1 popping out when it contacts the ice surface will increase.
