The invention relates to an environment-friendly road surface ice and snow melt coating material, a preparation method thereof and a using method thereof. Serious consequences such as traffic jam and the like can be caused by snow accumulation in winter; and at present, a snow removal method comprises passive snow removal and active snow removal, wherein in the passive snow removal, the operating efficiency of manual snow removal is low, mechanical snow removal is incomplete relatively in clearing, and for the spreading of a snow melt agent, substances with the snow melt effect are mixed simply only, so the spreading is non-uniform, and the snow melt agent dispersed to peripheral air has the major influence on environment; and the active snow removal is high in cost, and has a certain damage to structures of road surfaces, so the service life of roads is shortened. In the environment-friendly road surface ice and snow melt coating material, after being loaded on a carrier material, the snow melt substances are mixed with emulsified asphalt, water-soluble epoxy resin and a curing agent and sprayed on the road surfaces to form an ice and snow melt coating, so that the roads have the function of melting snow actively. By the environment-friendly road surface ice and snow melt coating material, an ice point of water is reduced to between -5 and -20 DEG C so as to clear the ice and snow of the roads, and the coating material has the sustained-release function, is high in coating adhesivity and wear-resisting effect, low in cost and convenient to maintain, and can prolong the life of the road surfaces effectively.

A snowthrower has a rotatable chute that directs the snow stream in different directions depending on the rotational position of the chute. A slidable hand grip is mounted on one of the handle tubes of the snowthrower. The hand grip can be slid down the handle tube by the operator to rotate the chute in a first direction. The hand grip can be slid up the handle tube by the operator to rotate the chute in a second opposite direction. The hand grip includes a rounded knob that the operator can grip with one hand. A latch is provided to lock the hand grip in an adjusted position on the handle tube.

A U-shaped handle is physically attached to the back of a deflector atop a snow directing chute on a snowthrower. The deflector pivots atop the chute to adjust the trajectory of a stream of snow being thrown by the snowthrower. The handle is gripped and moved up and down to effect a pivotal adjustment of the deflector. A pivotal latch is carried on the handle which latch protrudes into the open interior hand grip space of the handle. The latch is spring biased so that a detent on the latch engages with a toothed rack with the interengagement between the detent and the rack holding the deflector in an adjusted position. When the operator grips the handle and squeezes the fingers of the gripping hand closed, the latch is pivoted to remove the detent from the rack and thereby permit pivotal adjustment of the deflector.

A snowplow wing attached to the end of a snowplow blade may be manually adjusted into position to increase the operative width of the snowplowing surface, and otherwise capture or direct the flow of snow being plowed.

A snow removal or ground-surface cleaning apparatus that is pushed or pulled by a prime mover. The apparatus has a drum array that includes rows of triple-stepped blade-like fingers distributed evenly around a drum array. These fingers are stiffly flexible and can cleanly and efficiently pick up snow and debris from uneven ground surfaces.
