Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a material conveying device. Background Art

[0002] Mobile conveyors are divided into belt conveyors and bucket conveyors. Universal wheels are installed at the bottom of the conveyor, which can be moved at will according to the stacking position of the materials. Mobile belt conveyors are used in environments with small conveying inclination angles, and mobile bucket conveyors are used in environments with large conveying inclination angles. Mobile bucket conveyors have small buckets installed on the conveyor belt, so that materials will not fall back when the conveying inclination angle is large.

[0052] The upward movement mechanism is arranged above the roller 2 and is used to drive the roller 2 to leave the ground.

[0053] With this design, the transmission mechanism drives the hook 5 to move, and the hook 5 lifts the materials and transports the materials; when the roller 2 stops moving, the abutment mechanism increases the supporting force on the side plate 1, so as to prevent the conveying device from position shifting during operation and improve the stability of the device; the upward movement mechanism drives the roller 2 off the ground to prevent the roller 2 from moving when the device is working, thereby avoiding driving the device to move and ensuring the stability of the device.

[0054] In one embodiment, the abutment mechanism comprises:

[0055] Anti-slip plates 706 are slidably disposed on both sides of the roller 2 and are used to abut against the ground;

[0056] A slide bar 705 is provided at the upper end of the anti-slide plate 706;

[0057] The driving assembly is disposed on the supporting plate 6 and is used to drive the slide bar 705 to slide vertically.

[0058] With this design, the anti-slip plate 706 is fixedly connected to the slide bar 705 .

[0059] In one embodiment, the drive assembly comprises:

[0060] The screw rod 704 is passed through the slide bar 705 and is threadedly connected to the slide bar 705;

[0061] The second motor 702 is disposed at the upper end of the screw rod 704 and is used to drive the screw rod 704 to rotate;

[0062] The clearance groove 703 is provided on the support plate 6 and is used for the slide bar 705 to slide vertically;

[0063] The placement slot 701 is disposed above the clearance slot 703 and is used to place the second motor 702 .

[0064] In this design, the output shaft of the second motor 702 is fixedly connected to the screw rod 704 through a coupling; the second motor 702 is fixedly connected to the support plate 6; the screw rod 704 is rotatably connected to the support plate 6;

[0065] Start the second motor 702, and the second motor 702 drives the screw rod 704 to rotate, driving the slide bar 705 to move downward, thereby driving the anti-skid plate 706 to move downward and making the bottom end of the anti-skid plate 706 abut against the ground. The bottom end of the anti-skid plate 706 is flat, which is not easy to cause the device to slide, and has higher stability than the roller 2. The anti-skid plate 706 supports the roller 2 on both sides, so the anti-skid plate 706 has a stronger supporting force than the roller 2.

[0066] In one embodiment, the upward movement mechanism comprises:

[0067] The convex strip 709 is provided on one side of the anti-slide plate 706 close to the screw rod 704 and has inclined surfaces at both the upper and lower ends;

[0068] The movable bar 710 is slidably disposed on the bottom plate 707 and has two inclined surfaces matched with the convex bar 709 at one end close to the convex bar 709;

[0069] A first sliding groove 711 is provided on the bottom plate 707 and is used for the moving bar 710 to slide;

[0070] The power assembly is disposed on the moving bar 710 and is used to drive the roller 2 to slide vertically.

[0071] With this design, the convex strip 709 is fixedly connected to the anti-slip plate 706;

[0072] In one embodiment, the power assembly comprises:

[0073] A spring 712 is disposed in the first slide groove 711 and is disposed on an end of the moving strip 710 away from the protruding strip 709;

[0074] The connecting plate 708 is disposed on the upper end of the roller 2 and moves along with the roller 2;

[0075] A swing rod 713, one end of which is hinged to the moving bar 710, and the other end of which is hinged to the connecting plate 708;

[0076] The through slot 714 is disposed at the lower end of the first slide slot 711 and is used for the swing rod 713 to swing.

[0079] The bottom plate 707 is provided with a second sliding groove 716 for the movable column 715 to slide.

[0080] With this design, the moving column 715 is fixedly connected to the connecting plate 708; the original state of the convex strip 709 is: it abuts against the moving strip 710, and the compression spring 712 is deformed. At this time, the roller 2 is in contact with the ground and is easy to move. When the convex strip 709 moves downward with the anti-slip plate 706, when the anti-slip plate 706 contacts the ground, the convex strip 709 is no longer in contact with the moving strip 710, and the moving strip 710 slides in the direction of the convex strip 709. The convex strip 709 drives the rocker bar 713 to swing and under the guidance of the moving column 715, the connecting plate 708 moves upward, thereby driving the roller 2 to leave the ground, thereby reducing the possibility of position deviation of the device. It is worth noting that the through groove 714 limits the swing of the rocker arm 713, that is, limits the vertical displacement of the connecting plate 708, thereby ensuring that the roller 2 is not prone to shaking when it contacts the ground and rolls; it is also worth noting that the inclined surfaces at the upper and lower ends of the convex strip 709 cooperate with the two inclined surfaces at one end of the moving strip 710, which is conducive to the resetting of the moving strip 710 under the action of the convex strip 709.

[0081] In one embodiment, the bottom plate 707 is provided with a third sliding groove 717 for the anti-sliding plate 706 to slide;

[0082] The connecting plate 708 is provided with a fourth sliding groove 718 for the anti-sliding plate 706 to slide.

[0083] In one embodiment, the transmission mechanism comprises:

[0084] The transmission chain 303 is provided on one side of the side plate 1 and is used to drive the hook 5 to move;

[0085] The transmission wheels 301 are disposed at both ends of the transmission chain 303 and are used to drive the transmission chain 303 to transmit;

[0086] The transmission shaft 302 is disposed on the two transmission wheels 301 and is used to drive the transmission wheels 301 to rotate;

[0087] The first motor 304 is disposed on the side plate 1 and is used to drive one of the transmission wheels 301 to rotate.

[0088] In this design, a partition 4 connected to the hook 5 is fixedly connected to the transmission chain 303, and the partition 4 is fixedly connected to the hook 5; the first motor 304 is fixedly connected to the side plate 1, and the output shaft of the first motor 304 is fixedly connected to the transmission shaft 302 through a coupling; the transmission shaft 302 is fixedly connected to the transmission wheel 301; the transmission shaft 302 is rotatably connected to the side plate 1; the first motor 304 drives the transmission shaft 302 to rotate, driving the transmission wheel 301 to rotate, thereby driving the transmission chain 303 to transmit.

[0089] Working principle: during use, when the roller 2 stops moving, the abutment mechanism increases the supporting force on the side plate 1, so as to prevent the conveying device from being displaced during operation and improve the stability of the device; the upward movement mechanism drives the roller 2 off the ground to prevent the roller 2 from moving during operation, thereby preventing the device from being driven to move and ensuring the stability of the device; specifically, the moving column 715 is fixedly connected to the connecting plate 708; the original state of the convex strip 709 is: it abuts against the moving strip 710, and the compression spring 712 is deformed, at which time the roller 2 contacts the ground and is convenient to move; when the convex strip 709 moves downward with the anti-slip plate 706, when the anti-slip plate 706 contacts the ground, the convex strip 709 no longer abuts against the moving strip 710, and the moving strip 710 slides in the direction of the convex strip 709, and the convex strip 709 drives the swing rod 713 to swing and under the guidance of the moving column 715, the connecting plate 708 moves upward, thereby driving the roller 2 off the ground, reducing the possibility of position displacement of the device.
