Need to prove; The specific embodiment that only drives correction cylinder 23 vertical motions or horizontal motion with actuating device 24 in the preceding text has been introduced the correction process of above-mentioned band conveyor; In fact; Above-mentioned correction cylinder 23 is not limited in vertically or horizontal motion, can also realize correction through the motion of other directions, does not give unnecessary details one by one at this.
Other versions of above-mentioned band conveyor can also further be set.
In the another kind of specific embodiment, above-mentioned band conveyor can also comprise and detect whether sideslip of belt 22, and sends the detection part 25 that deviation correcting signal makes actuating device 24 actions, and detection part 25 is located at the both sides of head roll 21.
Adopt this version, when belt 22 was positioned at head roll 21 middle part normal operation, above-mentioned two detection parts 25 are detected, and self was consistent to the distance on belt 22 surfaces, and this moment, detection part 25 did not send actuation signal; When sideslip takes place in belt 22; Be that above-mentioned two detection parts 25 can detect that self is inconsistent to the distance on belt 22 surface; Detection part 25 just can send actuation signal to actuating device 24; Make actuating device 24 drive correction cylinder 23, thereby realize the effect of correction to suitable direction motion.
Can find out by above-mentioned working process; Adopt detection part 25 can find timely and accurately in early days that belt 22 has the trend of sideslip; Thereby feed back to actuating device 24 action of rectifying a deviation immediately; Make that belt 22 sideslips can be adjusted in time and correct, this has strengthened the accuracy and the promptness of belt 22 corrections greatly.
In the concrete scheme, above-mentioned detection part 25 can be specially sensor, and it has higher sensitivity and accuracy; Certainly, above-mentioned detection part 25 can also be detector switch.
Other specific constructive form of above-mentioned band conveyor can also further be set.
In the another kind of specific embodiment, the lower floor that above-mentioned correction cylinder 23 can be located at belt 22 is with 222 below, and the lower floor of belt 22 with 222 be coated on correction cylinder 23 the bottom, like this, the Assembly &Disassembly of convenient correction cylinder 23 and actuating device 24.Certainly, as shown in Figure 6, Fig. 6 is the front view of the another kind of specific embodiment of band conveyor that the utility model provides; Epipelagic zone 221 and lower floor that above-mentioned correction cylinder 23 also can be located at belt 22 are with between 222; And the lower floor of belt 22 with 222 be coated on the correction cylinder 23 the upper end; Like this; Can realize the correction of 23 pairs of belts 22 of cylinder of rectifying a deviation equally, and have the advantage of saving the space, be that this version makes the installation of actuating device 24 that inconvenience arranged slightly.The user can select according to actual needs voluntarily.
Further in the scheme, when the belt of above-mentioned band conveyor 22 was longer, above-mentioned band conveyor can also comprise at least two parallel rolls 26, and parallel roll 26 laterally arranges with head roll 21, and correction cylinder 23 is located between two parallel rolls 26.
Like this, in the material conveying process of band conveyor, because parallel roll 26 laterally arranges with head roll 21, parallel roll 26 can play certain supporting role in the correction process, further strengthens the working stability of band conveyor.
The utility model also provides a kind of mixing plant, comprises material-transporting system; Material-transporting system adopts aforesaid band conveyor.
Because above-mentioned band conveyor has above-mentioned technique effect, therefore comprise that the mixing plant of this band conveyor also should have identical technique effect, repeats no more at this.
