Description

Technical Field

[0001] The present invention relates to the technical field of scraper conveyors, and more specifically, to a scraper conveyor based on an intelligent gate device and an intelligent gate device. Background Art

[0002] A scraper conveyor is a conveying device that moves materials along a trough by means of a scraper chain moving in a closed trough. Scraper conveyors are widely used in industries such as coal mines, chemical mines, metal mines, and power plants, mainly for conveying materials.

[0003] A scraper conveyor has multiple discharge openings. When conveying materials, it is necessary to perform discharging operations at each discharge opening. In existing scraper conveyors, there is often no dedicated gate device at the discharge opening, resulting in difficulty in controlling and adjusting the discharge volume of the discharge opening and being unable to meet actual requirements. Although some scraper conveyors are provided with gate devices at the discharge opening, when the gate plate is closed, a groove portion (as shown in Figure 21 ) will be formed between the gate plate and the bottom plate of the bin. During scraper conveying, some materials will accumulate in the groove portion, and these materials will remain stationary in the groove portion for a long time. If the gate plate is in a closed state for a long time, this part of the materials will mildew and deteriorate, thus causing damage to the entire conveying device. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provides a scraper conveyor based on an intelligent gate device and an intelligent gate device.

[0005] To achieve the above object, the present invention provides the following technical solution: A scraper conveyor based on a gate device includes a bin, a scraper chain, and a driving device.

The gate device includes two cross beams and two gate units. Hinge seats are installed at both ends of the cross beam, and the cross beam has a first strip-shaped through groove; the gate unit includes two hydraulic telescopic rods and an opening and closing plate. Side convex blocks are fixedly connected to both sides of the opening and closing plate. One end of the hydraulic telescopic rod is hinged to the hinge seat, and the other end is hinged to the side convex block.

[0006] Further, the driving device is used to drive the scraper chain.

[0007] Further, the cross beam has an installation groove.

[0008] Further, the two cross beams are parallel to each other.

[0009] Further, the side convex block passes through the first strip-shaped through groove.

A fourth spring 6.9 is connected between one end of the second limiting block 6.8 and the second side groove 10.1. When there is no external force, the second limiting block 6.8 abuts against one end of the second side groove 10.1 and one end of the second insertion plate 10 is flush with the surface of the second limiting seat 6.2 close to the end seat 7; a strip-shaped convex part 4.6 is fixed in the receiving groove. The opening and closing plate 4 has an air inlet hole and an inner cavity communicated with the air inlet hole. Both sides of the strip-shaped convex part 4.6 are provided with air outlet holes 4.7 communicated with the inner cavity. Both sides of the receiving groove are provided with material discharging through grooves 4.8 communicated with the receiving groove. A fan unit 11 is installed at the air inlet hole.

[0102] The air outlet holes 4.7 on each side of the strip-shaped convex part 4.6 are arranged in a row at equal intervals; the tension springs 8.2 at the end plate 8.1 are divided into two rows, and the horizontal insertion plate 8 is located between the two rows of tension springs 8.2. The shutter unit can be in a first state, a second state, and a third state. In the first state, the end of the opening and closing plate 4 is flush with the inner side surface of the side plate 1.1, the upper surface of the first lifting plate 5.1 is abutted by the lower surface of the horizontal insertion plate 8, and the upper surface of the second lifting plate 6.1 is abutted by the bottom end of the side plate 1.1; in the second state, the upper surface of the first lifting plate 5.1 is abutted by the lower surface of the horizontal insertion plate 8, the upper surface of the second lifting plate 6.1 is flush with the upper surface of the bottom plate 1.2, and the end of the second insertion plate 10 abuts against the inner side of the side plate 1.1; in the third state, the end of the opening and closing plate abuts against the end of the corresponding opening and closing plate, the upper surfaces of the first lifting plate 5.1, the second lifting plate 6.1, and the bottom plate 1.2 are flush, and the end of the first insertion plate 9 abuts against the inner side of the side plate 1.1.

[0103] Working principle: For the scraper conveyor of the present application, a shutter device is installed at each blanking port, and the opening degree of the shutter device can be controlled by a hydraulic telescopic rod, so as to control the amount of material discharged from each blanking port. And for the most important working positions, that is, the gate is fully opened, the gate is opened halfway, and the gate is fully closed, these working states can work better.

[0104] As Figure 1 shown, at this time the gate is fully opened, the first lifting plate is pressed by the horizontal insertion plate, and the second lifting plate is pressed by the lower surface of the side plate of the bin. And at this time, the fan unit can be turned on, so that during the working process, small materials falling into the inner cavity of the opening and closing plate (since the positions of the first insertion plate and the second insertion plate are moving during work, it is inevitable that small materials will fall into the cavity) will be blown away by the air flow and fall through the blanking through groove. By extending the hydraulic telescopic rod, the opening and closing plate can close the blanking port. As Figure 4 shown, the gate is opened halfway. At this time, the first lifting plate is pressed by the horizontal insertion plate and the lower surface of the side plate, and at this time, since the second lifting plate is not pressed, it will rise, so that the second lifting plate is flush with the upper surface of the bin bottom plate (the rise of the second lifting plate will be restricted by the second limit seat slider, the second limit plate slider, the second limit seat chute, and the second limit plate chute, and the maximum rise height of the second lifting plate is just flush with the upper surface of the bin bottom plate). At this time, since the second lifting plate is flush with the upper surface of the bin bottom plate, and at this time, due to the shielding of the second insertion plate, the bin bottom plate and the second lifting plate form a flat material transportation surface, and the transportation effect is better (a small depression will be formed at the second insertion plate corresponding to the second chamfer. Since the area is small, the influence is small). When it is necessary to completely close the blanking port, as Figure 7As shown, both the first lifting plate and the second lifting plate are flush with the upper surface of the bin floor. Thus, the bin floor, the first lifting plate, and the second lifting plate form a flush material conveying surface (the upward movement of the first lifting plate is restricted by the first limit seat slider, the first limit plate slider, the first limit seat chute, and the first limit plate chute, and the maximum upward height of the first lifting plate is flush with the upper surface of the bin floor) (a small depression will be formed at the first insertion plate corresponding to the first chamfer and the second insertion plate corresponding to the second chamfer. Since the area is small, the impact is small). When the gate unit is opened from the closed state, as the hydraulic telescopic rod shortens, the first insertion plate will be squeezed by the side plate and retract into the first slot. And because the bottom end of the side plate will abut against the first chamfer, the first lifting plate will be pressed down by the side plate and move downward. And from Figure 4 the state where the gate plate is half open to Figure 1 the state where the gate plate is fully open, the second insertion plate will be squeezed by the side plate and retract into the second slot. And because the bottom end of the side plate will abut against the second chamfer, the second lifting plate will be pressed down by the side plate and move downward.
