Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is carried out below further detailed
It describes in detail bright.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention, it is not limited to this hair
Bright range.
Unless otherwise defined, all technical terms and scientific terms used herein are led with technology of the invention is belonged to
The normally understood meaning of the technical staff in domain is identical, and term as used herein in the specification of the present invention is intended merely to retouch
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of powder dispensing device with function of measuring, including controller, for connecting powder
Expect the dispenser frame 1 of truck spreader storage device, motor 4, drive sprocket 5, close switch are installed on the dispenser frame 1
6, driven sprocket 8 and several metering rotors 2；
The motor 4 has one, and motor 4 is connect with the drive sprocket 5, and the drive sprocket 5 connects with driven sprocket 8
It connects, driven sprocket 8 is connect with metering rotor 2；The revolving speed for being used to acquire metering rotor 2 close to switch 6, and signal will be acquired
Controller is fed back to, the controller closed loop adjusts the revolving speed of motor 4, and then realizes the rotational speed regulation to metering rotor 2；
The side of each metering rotor 2 is correspondingly provided with bin gate 7, and each bin gate 7 is individually connect with cylinder 3, is individually controlled by cylinder 3
Bin gate 7 opens and closes.
As the improvement of embodiment, the metering rotor 2 includes six, using six sections of isolating structures, is equipped with six material
Door 7, by cylinder 3, individually control opens and closes, it can be achieved that 400~2400mm dispenses the adjusting of width each bin gate 7.Different width are adapted to
Spend the demand that road surface dispenses operation.
As the further improvement of embodiment, six metering rotors 2 are integrated by assembly or welded connecting.By single
The whole driving of motor 4.The powder dispensing device that every section of more traditional rotor is operated alone, whole drive-type of the invention have knot
Structure is simple, good airproof performance, high reliability.Metering rotor revolving speed and chassis speed of operation auto-associating guarantee every square
Spreading amount does not change with speed and is changed.
As the improvement of embodiment, each metering rotor 2 uses encapsulated form, is integrally formed by encapsulation die, can be with
It is uniform that each hopper volume in border is effectively ensured.To guarantee each hopper to the accuracy of powder metering.It is encapsulated using entirety, together
When can guarantee 2 outer ring of metering rotor concentricity with higher, it is easier to guarantee between metering rotor 2 and dispenser frame 1
Gap it is uniform, and then realize powder sealing performance, guarantee powder will not by self weight from gap between the two flow out, cause
The error of powder spreading amount metering.
As the improvement of embodiment, rotor diameter and border hopper number ratio have between 20~30 in each metering rotor 2
Effect guarantees charging efficiency, measuring accuracy and the spreading uniformity of powder.Relative to fixed metering rotor outer diameter, rotor border
Hopper quantity number will have a direct impact on dispensing device maximum spreading amount and small spreading amount dispense uniformity.Border hopper number mistake
It when more, cannot adequately be filled when powder falls to dispenser above dispenser, the maximum of dispensing device is caused to dispense
Amount is restricted, and is extremely difficult to the requirement of construction party；When border hopper number is very few, powder falls to ground in two neighboring hopper
When time difference it is larger, vehicle advance during when will lead to small spreading amount, the powder of spreading presents apparent wavy, dispenses
Uniformity is poor.
As the improvement of embodiment, as shown in figure 4, in the metering rotor 2, it is left-handed between each adjacent two rubber covered roll 21
Angle is 4 °, guarantees certain installation angle, is conducive to reduce the resistance and improve the uniformity dispensed that metering rotor 2 rotates.
In use, as shown in figure 5, powder is filled above dispensing device to 2 top U-type groove of metering rotor by self weight
It is interior, after metering rotor 2 drives the powder in U-type groove to turn to below dispensing device, ground is dropped down by gravity.
Concrete operating principle is: the unlatching quantity of bin gate 7 is controlled by cylinder 3, so that controlling powder dispenses width；
Drive sprocket 5 is driven by motor 4, drive sprocket 5 connect by chain with driven sprocket 8 and transmit torque, band
Dynamic metering rotor 2 rotates, and by acquiring the revolving speed of metering rotor 2 close to switch 6 and feeding back to controller, and closed loop adjusts motor
4 revolving speeds control the stabilization of speed of metering rotor 2, and then guarantee constant spreading amount.
When speed variation, controller passes through the revolving speed for adjusting 4 revolving speed final adjustment metering rotor 2 of motor, to realize
The revolving speed of metering rotor 2 and the real-time matching of speed.And then guarantee that every square of spreading amount does not change with speed and changed.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
