Abstract

The invention belongs to road building equipment, and provides a powder spreading car. The powder spreading car solves the problem that in the prior art, a square powder tank is prone to disturbing powder spiral conveying, a large amount of powder is prone to remaining and stacking on the bottom of the powder tank, and ramming of the powder tank is not uniform. The powder spreading car comprises acontrol system, a car body, a powder tank and a rear box body, wherein the powder tank and the rear box body are fixedly mounted on the car body, a spiral conveying opening is formed in the rear endof the powder tank, the powder tank communicates with the rear box body through the spiral conveying opening, the section of the powder tank is a round or polygon including at least six sides, a manhole is formed in the powder tank, a charging mechanism is arranged on the upper portion of the powder tank, at least one feeding spiral rod is arranged on the bottom of the powder tank, the tail end ofthe feeding spiral rod is located on the spiral conveying opening, a material door is arranged on the bottom of the rear box body, and an exhaust opening is formed in the upper portion of the rear box body; the power part of the car body provides a power source for the powder tank and the rear box body; and the control system controls a charging mechanism of the powder spreading car to carry outcharging, a feeding spiral rod to rotate and the material door to be opened and closed.

Description

technical field [0001] The invention belongs to the technical field of road construction equipment, in particular to a powder spreading vehicle. Background technique [0002] As a special equipment for roadbed powder spreading, the powder spreader is widely used in the spreading of various powder materials such as cement and lime in various roadbed constructions such as roads and railways. The powder tank is an important part of the powder spreading vehicle, which is used to transport powder to the rear box. [0003] In the existing powder spreading vehicles, single or multiple screw rods arranged on the same horizontal plane are generally used for feeding, and the material in the powder tank is conveyed by the rotation of the screw rod. With the rotation of the screw rod, the powder material It moves along the powder tank in the form of sliding, which is suitable for dry granular or powdery materials. However, it is easy to cause a large amount of residual powder to accum...
