Technical Field

[0001] The utility model relates to the technical field of conveyor belt deviation correction, in particular to an automatic deviation correction device for a sand and stone conveyor belt. Background Art

[0002] When the sand and gravel conveyor belt is transporting sand and gravel, in order to avoid the deviation of the conveyor belt during operation, it is necessary to set an automatic correction device on the conveying device. The automatic correction device is mainly composed of three sets of rollers. The middle roller is horizontal, and the rollers on both sides are inclined to form an inverted prism shape to realize automatic correction of the conveyor belt.

[0003] In the traditional automatic deviation-correcting device for sand and gravel conveyor belts, the inclination angles of the rollers on both sides are usually fixed. Therefore, when the conveyor belt passes through the device, the lifting height on both sides is also fixed. It is impossible to freely control the height of both sides of the conveyor belt according to transmission needs, which is inconvenient to use. In view of this, we propose an automatic deviation-correcting device for sand and gravel conveyor belts. Utility Model Content

[0009] Preferably, the second cylinder body is horizontally fixedly arranged on the adjustment structure, and the second cylinder piston end is fixedly connected to the corresponding side of the mounting plate.

[0010] Preferably, the matching roller and the side roller are arranged in parallel, and the matching roller and the opposite sides of the side baffle are close to each other.

[0011] Preferably, the adjustment structure includes a first cylinder and a side plate, the bottom of the side plate is movably connected to the top of the base through the first cylinder, one side of the side plate is rotatably connected to the opposite end of the side roller through a bearing, and one end of the articulated seat is rotatably connected to the opposite end of the side roller through a bearing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model installs the side rollers through an articulated seat and an adjusting structure. Therefore, during the use of the device, the side rollers can be driven by the adjusting structure to rotate vertically around the articulated seat as needed, so that the angles of the side rollers can be freely adjusted. Therefore, the two groups of side rollers cooperate with the horizontal rollers to form an inverted pyramid shape with different opening degrees. When the sand and gravel conveyor belt passes through this inverted pyramid, the heights of both sides of the sand and gravel conveyor belt will change accordingly with the different inclination angles of the two groups of side rollers, which can better meet the needs of use. Therefore, the utility model has the advantage of being able to freely adjust the heights of both sides of the sand and gravel conveyor belt as needed while satisfying the automatic deviation correction of the sand and gravel conveyor belt.

[0015] 2. The utility model is provided with a second cylinder and a limiting structure on the adjusting structure. When the two groups of side rollers cooperate with the horizontal roller to form an inverted prism shape and the sand and gravel conveyor belt passes through the inside of the inverted prism for automatic deviation correction, the second cylinder can drive the limiting structure to move along the side rollers, so that the side baffles of the limiting structure are in contact with the side edges of the sand and gravel conveyor belt, and then the cooperating rollers in the limiting structure are controlled to descend, and then the cooperating rollers cooperate with the side rollers to clamp the side edges of the sand and gravel conveyor belt. Therefore, the side baffles, cooperating rollers and side rollers are combined to form a concave clamping groove, which stably clamps and limits the side edges of the sand and gravel conveyor belt, and cooperates with the inverted prism to achieve a better and more stable effect of automatically correcting the sand and gravel conveyor belt.

At this time, the two groups of side rollers 3 cooperate with the horizontal roller 7 to form an inverted prism shape, and then the sand and gravel conveyor belt passes through the inside of the inverted prism. The inverted prism can realize automatic deviation correction of the sand and gravel conveyor belt, and during the use of the device, the inclination angle of the side roller 3 can be freely adjusted by adjusting the structure 4. As the inclination angles of the two groups of side rollers 3 are different, when the sand and gravel conveyor belt passes through the inverted prism, the heights of both sides of the sand and gravel conveyor belt will also change accordingly, so as to better meet the use needs;

[0024] Specifically, the adjustment structure 4 includes a first cylinder 401 and a side plate 402. The bottom of the side plate 402 is movably connected to the top of the base 1 through the first cylinder 401. One side of the side plate 402 is rotatably connected to the opposite end of the side roller 3 through a bearing. One end of the hinged seat 201 is rotatably connected to the opposite end of the side roller 3 through a bearing. By controlling the extension and retraction of the first cylinder 401, the side plate 402 on the top of the first cylinder 401 will drive the side roller 3 to rotate vertically around the hinged seat 201.

[0025] Furthermore, the bottom end of the first cylinder 401 is hingedly connected to the top of the base 1 , and the piston end of the first cylinder 401 is hingedly connected to the bottom of the side plate 402 .

[0026] In a specific embodiment, the regulating structure 4 is arranged with a limiting structure 6 through the second cylinder 5 on the top of one side of the side roller 3, the limiting structure 6 includes a mounting plate 601, a side baffle 602, a third cylinder 603, a mounting block 604 and a matching roller 605, the mounting plate 601 is horizontally arranged, and the side baffle 602 is vertically arranged on one side of the bottom of the mounting plate 601, the mounting block 604 is arranged on the side of the bottom of the mounting plate 601 facing away from the side baffle 602 through the third cylinder 603, and the matching roller 605 is rotatably installed on the mounting block 604 on the side of the side baffle 602 through the bearing, when the two groups of side rollers 3 cooperate with each other in the water The flat roller 7 forms an inverted prism shape. When the sand and gravel conveyor belt passes through the inside of the inverted prism for automatic deviation correction, the second cylinder 5 can drive the limiting structure 6 to move along the side roller 3, so that the side baffle 602 contacts the side of the sand and gravel conveyor belt, and then control the third cylinder 603 to drive the matching roller 605 to descend, and then the matching roller 605 cooperates with the side roller 3 to clamp the side of the sand and gravel conveyor belt. Therefore, the side baffle 602, the matching roller 605 and the side roller 3 are combined to form a concave clamping groove, which stably clamps and limits the side of the sand and gravel conveyor belt, and together with the inverted prism, the effect of automatically correcting the sand and gravel conveyor belt is better and more stable.

[0027] Specifically, the cylinder body of the second cylinder 5 is horizontally fixedly arranged on the adjustment structure 4 , and the piston end of the second cylinder 5 is fixedly connected to the corresponding side of the mounting plate 601 .

[0028] Furthermore, the bottom of the side baffle 602 is an arc-shaped opening, which fits the surface of the side roller 3. The arc-shaped opening facilitates the side baffle 602 to fit closely with the side roller 3 to limit the side of the sand and gravel conveyor belt.

[0031] Working principle: When the gravel conveyor belt is automatically corrected, first, the base 1 is installed on the gravel conveyor frame, and then, with the cooperation of the hinge seat 201, the side roller 3 can be driven to rotate vertically around the hinge seat 201 through the adjustment structure 4, so as to adjust the inclination angle of the side roller 3. At this time, the two groups of side rollers 3 cooperate with the horizontal roller 7 to form an inverted prism shape, and then the gravel conveyor belt passes through the inside of the inverted prism, and the inverted prism can realize the automatic correction of the gravel conveyor belt;

[0032] Secondly, during the use of the device, the inclination angle of the side roller 3 can be freely adjusted by adjusting the structure 4. As the inclination angles of the two sets of side rollers 3 are different, when the sand and gravel conveyor belt passes through the inverted prism, the heights of both sides of the sand and gravel conveyor belt will also change accordingly, thereby being able to better meet the use needs;

[0033] Finally, when the sand and gravel conveyor belt passes through the inside of the inverted prism for automatic deviation correction, the second cylinder 5 can drive the limiting structure 6 to move along the side roller 3, so that the side baffle 602 contacts the side of the sand and gravel conveyor belt, and then control the third cylinder 603 to drive the matching roller 605 to descend, and then the matching roller 605 cooperates with the side roller 3 to clamp the side of the sand and gravel conveyor belt. Therefore, the side baffle 602, the matching roller 605 and the side roller 3 are combined to form a concave clamping groove, which stably clamps and limits the side of the sand and gravel conveyor belt, and together with the inverted prism, the effect of automatically correcting the sand and gravel conveyor belt is better and more stable.
