Abstract
One kind is sowed meter and sows car, is related to highway maintenance field.Wherein sowing meter includes metal shell, the rotating shaft being placed in metal shell, and be sheathed in rotating shaft and with the rubber ring body of rotating shaft synchronous axial system, ash inlet and ash hole are offered on metal shell, the external side of rubber ring is provided with axial projections, and the rubber chamber that material is sowed for accommodating is surrounded between the adjacent projection of each two；By controlling the rotating speed of rubber ring body, the material of sowing entered by ash inlet is delivered to ash hole by rubber chamber.Compared with prior art, the rotating speed by controlling rubber ring body of the invention, expects that being transported to ash hole in the case where rubber chamber drives is sowed by sowing for ash inlet entrance, because the volume for wanting to exchange is default, therefore can easily control the amount of sowing of unit interval.
Description
Technical field
The present invention relates to highway maintenance field, sow meter more particularly, to one kind and sow car.
Background technology
The powder such as cement, lime, flyash it is uniform sow be highway build and maintenance process in essential stream
Sowing for the molecules such as journey, Nacl, snow-melting agent is winter fast melt most effective means icy on road, mesh
The powder such as cement during preceding highway is built sows major part still by being accomplished manually, but artificial spreading cement, lime
Extremely inefficient and spreading amount is extremely uneven and influences construction environment.
The A of Chinese patent CN 103147418 disclose a kind of backpack Snow Agent and sow car.Including vehicle frame, install
In the wheel of vehicle frame both sides；Vehicle frame is provided with aggregate bin, and aggregate bin bottom opening lower section is provided with sheds disk, and wheel is passed
Moving axis is driven with the axostylus axostyle for shedding disk by driving member and coordinated.However, it sheds disk rotating speed and to sow width complete
Limited by vehicle wheel rotational speed, disk rotating speed is shed under same speed for certain value, it is impossible to which density, and this are sowed in regulation
Kind of mechanism sows that precision is relatively low and sowing disk and filter screen needs periodic cleaning to safeguard.
In addition small part also is paved by water dispenser truck spreader, road deicing mainly sows Nacl and snow removing by snow sweeper
Agent is completed, but the sowing apparatus in current cement truck spreader and snow sweeper mainly sow bottom of chamber portion by regulation
Openings of sizes changes the amount of sowing, and the amount of sowing to powder ash does not carry out accurate measurement and control, and this mechanism is not
The amount of sowing of powder or molecule can accurately be controlled.When powder gray density changes or occurs jolting, necessarily affect
The amount of sowing of powder ash, causes to sow uneven.
