Abstract

The invention relates to a variable discharge component of a snow-melting agent sprayer, which belongs to the field of snow removing implements and mainly achieves uniform distribution of a snow-melting agent by changing spray quantity with vehicle speed of the sprayer and regulating and controlling the spray quantity when the snow thicknesses of a road section are different. The snow-melting agent sprayer has the main technical solution and the structure that: the sprayer comprises a storage bin, a belt conveyor, a discharging hopper and a rotary spray tray and is characterized in that a lower mouth of the discharging hopper is provided with a vane wheel rotary discharger controlled by a binary variable for the spray tray to discharge; the discharger comprises an end cover, a cylinder casing, an upper charging port, a lower discharging port and a vane wheel which is horizontally loaded with a trough in the casing; a rotary soft shaft and friction wheels with proportional vehicle speed, torque and rotary speed are used for driving to discharge at real-time vehicle speed; the upper charging port is provided with a radial gate which moves according to snow thicknesses; the radial gate is used for changing the volume of the trough; and the moving stroke of the radial gate can be controlled by a push-pull soft shaft in a cab. The snow-melting agent sprayer has simple structure, low cost, reliable control, no special technical requirement for operators, easy maintenance and arbitrary working speed, and can save the utilization quantity of the snow-melting agent.

Description

The Snow Agent spreader of binary variable regulation and control blowing

Technical field

The invention belongs to the snow removing tool field, particularly Snow Agent spreader parts.

Technical background

Present widely used various Snow Agent spreaders, only with flashboard regulation and control drain hole area, can not smart amount control spreading amount, more can not regulate and control spreading amount to adapt to highway section regional area accumulated snow difference in thickness, and the intersection problem that repeats to shed, existing publication 200810155102.5 intelligent pre-wetting snow-removing cars; Patent 200610047566.5 snow removing vehicle intelligent spreading control systems all are the problems that changes the control spreading amount with the speed of a motor vehicle, are characterized in that the observing and controlling device is various, the cost height.

Goal of the invention

The purpose of this invention is to provide and a kind ofly can change the spreader that binary variable regulation and control blowing device is arranged of shedding Snow Agent quantity with speed of a motor vehicle speed.

Summary of the invention

This Snow Agent spreader has been introduced the trough volume of binary variable regulation and control blowing device and the notion of dispensing speed, and designed adjustable blowing device, be installed in the feed leakage bucket end opening, on rotation is dumped, be used for by the real-time speed of a motor vehicle and and snow thickness continuous will hide with bin stock, Snow Agent in the feed leakage bucket that conveyer links, deliver to and shed dish and go up rotation and throw the road surface.The structure of its blowing device and principle are formed, be installed in the blade wheel that axle in the cylinder case is level and be connected the feed leakage bucket end opening together with the case overall fixed, what dock with it is the charging aperture of blowing device, what the bottom was corresponding successively is, have hopper rotary vane wheel, drain hole down, horizontally rotate shed dish and CD-ROM drive motor, have at the charging aperture place along the blade wheel shaft to be used to regulate and control blade wheel hopper volume to the arc flashboard of telescopic moving, promptly material-dividing groove quantity what.But can be manually also the machine control realize straight-line displacement control at driver's cabin.The blade wheel shaft that is stamped level at blowing device one side stretches out, and connects rotary flexible shaft with all kinds of motors of ratio speed of a motor vehicle torque and connects, and realizes that the blade wheel is that hopper changes hopper speed by speed of a motor vehicle speed; Can also take turns spouse's male part tooth bar filling hopper plug-in mounting wheel with blade does not have side board side plug-in mounting vertically to the long hopper of blade wheel space, changes blade and takes turns each hopper volume, realizes the stepless regulating of hopper volume.Wherein the rectilinear path regulation and control of the arc flashboard of blowing device or spouse's assembly tooth bar filling hopper plug-in mounting wheel can both realize with following mechanism, small-sized hydraulic cylinder electro-hydraulic servo mechanism, push-and-pull flexible axle assembly, lead screw pair, rack-and-pinion synchronous motor, servomotor and straight motor of straight line and sensor feedback control etc.The rotation of blowing device blade wheel shaft, available have the hydraulic oil or the pump of fixed proportion relation to make execution unit by motor with the chassis speed of a motor vehicle, with stepper motor, servomotor, by the sensor signal driving of the speed of a motor vehicle.With the dc speed-regulating motor system drive of following the boat speed of a motor vehicle; The simplest available rotary flexible shaft and ratio speed of a motor vehicle torque wheel are got torque rotary speed on the road surface or in the tire friction, also can drive the rotation of blowing device blade wheel shaft with gear or noncontact electromagnetic torque at parts such as power transmission shaft or wheel hubs.

But case antifriction metal (AFM), plastics, the rubber material of blowing device blade wheel, also can be made into the low-surface-energy hydrophobic property in the hopper and prevent that the ditch angle from sticking clout, the blade edge of blade wheel can be avoided the big pellet of card along making elasticity, sheds dish and makes hydrophobic property and can spray the snow melt liquid Snow Agent pellet of prewetting herein.The blowing device can be made the revolution feeding machine with miniature corrugated sidewall troughed belt, also can being connected on Lou, trailing flank, the conveyer of material mouth also can be the revolution drag chains, back and forth pushing away discharge mechanism, the continuous feed of the lifting section of dumping, can be that spool thin skin band pulls feeding, air bag slope feed.It also can be the chassis railway carriage that bin stock is hidden.

The good effect of invention

This Snow Agent spreader adopts modularized design, and simple in structure, cost is low, and control is reliable, easy care easy to operate, and the operation quality velocity efficiency all has positive role, can save the use amount of Snow Agent.
