Abstract
The utility model relates to an autodumper, which utilizes exhaust heat of an engine to heat a carriage floor, and belongs to the control valve which controls the exhaust flow direction of the exhaust pipe of the engine, in particular to a three-way rotary valve of the exhaust pipe for heating the carriage floor. The three-way rotary valve consists of a valve core and a valve body. The valve body is a cylindrical barrel with the sealed bottom and the open upper part. A connecting flange is arranged on the open upper part. Three ports are arranged on the wall of the barrel. The valve core is a disc-shaped upper cover which is vertically connected with an arc surface shaped valve block plate on the bottom surface. The arc surface of the valve block plate is matched with the inner wall of the barrel and size of the valve block plate is appropriate to block a port on the barrel. Screw holes arranged uniformly on the periphery of the disc-shaped upper cover correspond to the screw holes on the connecting flange of the barrel. In the utility model, the carriage floor can be heated by using exhaust gas of the engine so that moist and water containing bulk cargo can be dumped conveniently by the autodumper in the cold region in winter, thereby reducing the labor intensity of workers, improving the transportation efficiency and reducing the transportation cost.
Description
Technical field
The utility model relates to the dump truck that utilizes engine exhaust heat vehicle cabin floor, belong to control engine exhaust pipe blast air to control valve, especially for the outlet pipe Three-way rotary valve of platform floor heating.
Background technique
Cold area in the winter time, dump truck is moist in transportation, when containing the bulk goods of moisture, and platform floor and bulk goods can freeze adhesion phenomenon, cause bulk goods in the compartment to be difficult to dump and maybe can't dump totally.Often need manually to clear up, reduced conveying efficiency, increased cost of transportation.
The model utility content
The purpose of this utility model is to provide a kind of outlet pipe Three-way rotary valve that is used for the platform floor heating, can utilize engine exhaust vehicle cabin base plate, make dump truck in the winter time cold area dump humidity easily, contain the bulk goods of moisture, reduce working strength of workers, improve conveying efficiency, reduce cost of transportation.
The purpose of this utility model is achieved in that a kind of outlet pipe Three-way rotary valve that is used for the platform floor heating, constitute by spool and valve body, the structure of valve body is its open topped of cylindrical tube of bottom lock, on at an upper portion thereof uncovered adpting flange is being set, three ports are being set on barrel wall, the structure of spool is discoidal loam cake, vertical affixed the valve closure plate of arc surface shape on its bottom surface, the arc surface of valve closure plate matches with cylinder inboard wall, the size of valve closure plate is advisable with a port that can keep off on the tight cylindrical shell, and is corresponding with the screw on the cylindrical shell adpting flange at the screw of the uniform setting of discoidal loam cake periphery.
During use, on three ports of the utility model valve body interface is being set respectively, an interface of three interfaces connects the dump truck engine exhaust pipe, and another interface connects muffler assembly, and the 3rd interface is communicated with the intake duct of platform floor.Below 0 ℃ the time, need the platform floor heating Celsius, unload the connecting bolt of lower cylinder body adpting flange, rotational valve core, make the valve closure plate close connecting passage with muffler assembly, this moment, engine exhaust pipe was communicated with the gas-entered passageway of platform floor, with connecting bolt spool loam cake and cylindrical shell was fixed.More than 0 ℃ the time, shed holding down bolt Celsius, the valve closure plate of spool rotated, make the valve closure plate close the gas-entered passageway of platform floor, this moment engine exhaust pipe and muffler assembly channel connection, the exhaust of motor is discharged by muffler assembly.Because Celsius below 0 ℃ the time, the utility model has been realized the exhaust gas heat vehicle cabin base plate by motor, in the winter time the cold area dump truck in the roping humidity, contain the bulk goods of moisture, the phenomenon that platform floor and bulk goods freeze adhesion can not take place, can come down in torrents easily humidity, contain the bulk goods of moisture, reduce working strength of workers, improve conveying efficiency, reduce cost of transportation.
