Abstract
The utility model provides an equidifferent powder spreading vehicle and is mainly used for solving the problems of screw feed conveyor damage and poor feed spreading density and uniformity are easily caused due to the fact that the construction efficiency is increased in a vehicle speed increasing manner in the prior art. The equidifferent powder spreading vehicle comprises a controller, a chassis and a feed bin which arranged on the chassis, wherein screw feed conveyors are arranged in the feed bin. According to the equidifferent powder spreading vehicle, the spreading density is unrelated to vehicle speed, a good powder spreading effect can be obtained as long as the vehicle speed is in a recommended range, and the construction efficiency can be increased to the maximum.
Description
Technical field
The utility model relates to the asphalt macadam dispensing apparatus, specifically is used for the feed of rubble spreading hopper, belongs to the road building equipment technical field.
Background technology
Be similar in the equipment of granular material of powder in equal difference formula powder truck spreader or spreading characteristic, the density of spreading material with and the uniformity of spreading be the construction leading indicator, simultaneously, the efficient of construction also is the factor that must take into account.
If come lifting construction efficient in the mode that improves the speed of a motor vehicle, will cause the conveying amount of screw input feeder also to increase thereupon, even exceed the efficient working range of screw input feeder, may cause screw input feeder to damage; Simultaneously, come lifting construction efficient in the mode that improves the speed of a motor vehicle, its required power may surpass the maximum power that automobile chassis can provide, and causes equipment to work, thereby causes the density of spreading material and the uniformity variation of spreading.
Simultaneously, need to control material jaw opening during conducting powder material spreading with the control load, the traditional control system of control material jaw opening size mainly contains following two kinds: a kind of is to adopt rocking bar-sawtooth bin gate detent mechanism, and another kind is the spiral screw rod detent mechanism.This two kinds of detent mechanism apertures precise control, to handle repeatable accuracy high, but each adjustment is carried out manual operation after all need shutting down, and can't satisfy the demand of automation control.
Summary of the invention
The utility model provides a kind of equal difference formula powder truck spreader, mainly having solved existing mode with the raising speed of a motor vehicle comes lifting construction efficient easily to cause screw input feeder to damage, can't automatically control load, the density of spreading material with and the poor problem of the uniformity of spreading.
Concrete technical solution of the present utility model is as follows:
This equal difference formula powder truck spreader comprises controller, chassis and is arranged on feed bin on the chassis, be provided with three and be arranged on conplane screw input feeder in the described feed bin, vertical distance between the screw input feeder is identical, and screw input feeder is welded and fixed and is arranged at bin bottom; Screw input feeder is provided with for the driving mechanism that drives screw input feeder away from feed bin discharge hole one end, and screw input feeder is provided with rear side bin-level sensor near feed bin discharge hole one end, also is provided with the spiral speed measuring device on the screw input feeder; Be provided with vehicle speed detector device on the described chassis; The output of the output of described vehicle speed detector device, rear side bin-level sensor, the output of spiral speed measuring device all are connected with the input of controller, and the output of controller is connected with driving mechanism; Described each screw input feeder is made of screw rod and the helical blade that is arranged on the screw rod, and the pitch between each helical blade increases progressively to material outlet moving direction equal difference along material.
Above-mentioned driving mechanism is hydraulic unit driver.
The utility model has the advantage of:
The spreading density of this equal difference formula powder truck spreader and the speed of a motor vehicle are irrelevant, as long as just can obtain good powder spreading effect in the vehicle speed range of suggestion, and can improve to greatest extent efficiency of construction; The utility model screw input feeder group can realize without dead angle storage, and the space of the feed bin rate that can maximize the use.
Description of drawings
Fig. 1 is equal difference formula powder truck spreader schematic diagram;
Fig. 2 is that screw input feeder is at feed bin inner structure schematic diagram;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in Figure 1:
This equal difference formula powder truck spreader comprises controller, chassis and is arranged on feed bin on the chassis, be provided with three and be arranged on conplane screw input feeder in the feed bin, vertical distance between the screw input feeder is identical, and screw input feeder is welded and fixed and is arranged at bin bottom; Screw input feeder is provided with for the driving mechanism that drives screw input feeder away from feed bin discharge hole one end, and driving mechanism is generally selected hydraulic unit driver.The quantity of screw input feeder and length are to determine according to the long L of feed bin and wide B, wherein the α angle is the angle of hypotenuse and horizontal plane, if in the situation that the space allows, the α angle can also equal 90 °, the α angle is not less than the angle of repose of material, avoid generally all being set to three in problems such as the stagnant material of spiral wall.Each screw input feeder is made of screw rod and the helical blade that is arranged on the screw rod, and the pitch between each helical blade increases progressively to material outlet moving direction equal difference along material.
Screw input feeder is provided with rear side bin-level sensor near feed bin discharge hole one end, what level sensor continued transmits the information of material level in the feed bin to controller, when the material level in the feed bin is lower than an amount, controller can promote the rotating speed of screw input feeder, and the rotating speed after this promotes can continue the rotating speed of t time second again and return to theoretical rotating speed after level-sensing device transmits the full signal of material; Also be provided with the spiral speed measuring device on the screw input feeder, the spiral speed measuring device is the device that detects the screw input feeder rotating speed, the spiral speed measuring device can pass to controller with the rotating speed of the screw input feeder that detects, controller can compare the rotating speed that transmits and the theoretical rotational speed that calculates, and carries out FEEDBACK CONTROL; Be provided with vehicle speed detector device on the chassis, vehicle speed detector device can be to utilize approach switch to detect the indirect speed of a motor vehicle that rotating speed of transmission shaft obtains, and also can be other the speed measuring device such as radar velocity measurement; The output of the output of vehicle speed detector device, rear side bin-level sensor, the output of spiral speed measuring device all are connected with the input of controller, and the output of controller is connected with driving mechanism.
During use, at first need the density of spreading material in the controller input, can make bulk density also can be mass density.Control the rotating speed of screw input feeder according to the current speed of a motor vehicle; If calculate that the rotating speed of spiral has exceeded the permission rotating speed of screw input feeder maximum then controller can be reported to the police, the prompting speed of a motor vehicle is too high; If calculate the rotating speed of gained screw input feeder from maximum permissible speed, controller can point out the speed of a motor vehicle excessively low, promotes the speed of a motor vehicle to obtain better execution conditions.
