Description

Technical Field

[0001] The invention belongs to the technical field of elevators, and in particular relates to a shaping mechanism for an elevator hopper. Background Art

[0002] A material elevator is a mechanical equipment used for vertical transportation of bulk materials. It drives the hopper to circulate through a chain to continuously transfer and transport the materials. It is widely used in feed mills, flour mills, mines, port terminals and other scenes. In the prior art, when ordinary Z-shaped elevators lift and transport materials, they all suspend multiple hoppers through conveyor chains to transport materials. In actual use, in order to prevent materials from falling through the gaps between the hoppers during transportation, a circle of overlapping edges is specially designed at the top edge of the hopper to prevent material from spilling by overlapping the front and rear hopper overlapping edges. However, when the hopper overlaps and moves downward through the sprocket, since the front hopper overlapping edge overlaps the rear hopper overlapping edge, when it moves from a high position to a low position, the front hopper overlapping edge presses the rear hopper overlapping edge, causing the hopper to tilt and overlap vertically in an overturned state, which will cause the hopper to flip and collide during the downward process, thereby causing all the materials to spill.

[0003] The Chinese patent with the authorization announcement number CN208412966U discloses a downward bucket shaping mechanism at the upper part of a rotary bucket elevator, which includes a corner box, two sprockets on the upper part of the corner box rotate clockwise, which drives two chains to move from top to bottom, and a conveying bucket is mounted on the chain, and an adjustment cover or a protruding adjustment device is fixed at both the front and rear ends of the conveying bucket; a blocking block is fixed on the front and rear side walls of the corner box respectively, and a fixing bracket and a blocking block are fixed on the front and rear side walls of the corner box, and the blocking block is fixed on the conveying bucket Adjustment cover or protruding adjustment device The blocking block is used to frictionally block the adjustment covers or the tops of the raised adjustment devices on both sides of the conveying hopper passing by, forcing the conveying hopper to deflect at an angle during the movement, changing the overlapping position between the overlapping edges of adjacent conveying hoppers, changing the overlapping edge of the front conveying hopper to press the overlapping edge of the rear conveying hopper, so that the overlapping edge of the rear conveying hopper presses the overlapping edge of the front conveying hopper. In this way, the front conveying hopper will not have any resistance when it goes down, and will not interfere with the adjacent conveying hopper, so as to avoid the conveying hopper of the Z-shaped bucket elevator from tilting or running in a vertical overlapping state when the conveying hopper passes through the sprocket to go down.

[0004] However, the above patent still has the following disadvantages:

[0005] When changing the overlapping mode between the hoppers, the above patent forcibly presses the front hopper to tilt it, and then the overlapping edge of the front hopper presses the overlapping edge of the rear hopper to tilt the rear hopper until the two overlapping edges are separated, the overlapping edge of the front hopper is pressed down, and the rear hopper is reset under the action of gravity. However, the above patent must make the hopper actively tilted to achieve the change of the overlapping mode to avoid the overlapping edges interfering with each other when the hopper moves down, causing the hopper to tip over. In this way, the material in the hopper is easy to spill when the hopper is tilted, and the above patent is difficult to truly guarantee the stability of transportation. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention solves the following technical problems:

[0007] During the process of the hopper conveying materials, the hoppers are connected as a whole through the buckling between the first lap joint and the second lap joint, thereby improving the carrying effect, and the gap between the hoppers is covered by the buckling of the first lap joint and the second lap joint to prevent the material in the hopper from spilling out of the gap. When the hopper enters the downward conveying range, the mutual friction between the friction wheel and the friction plate drives the second lap joint and the first lap joint to rotate to change the overlapping mode, so that when the hopper moves downward and the overlapping part of the front hopper and the rear hopper is separated, the first lap joint and the second lap joint can be easily separated to avoid the problem of tipping caused by mutual interference between the hoppers, and in the process of changing the overlapping mode and moving the hopper downward, the hopper does not tilt to prevent the material in the hopper from spilling.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shaping mechanism for an elevator bucket, comprising a chain, a plurality of buckets are evenly distributed and hinged between two chains, a mounting plate is fixedly connected at both sides of the opening of each hopper, the outer sides of the two mounting plates on each hopper are rotatably connected with a first lap joint and a second lap joint respectively, the adjacent first lap joints and second lap joints can be interlocked, each of the first lap joints and the second lap joints are provided with arc-shaped slide grooves at both ends, a connector fixedly connected to the corresponding end of the mounting plate is slidably connected in each slide groove, and a corner box covering the chain and the bucket is provided on the outer sides of the two chains.

[0009] During the process of the hopper operating to transport materials, the hoppers are connected as a whole through the buckling between the first lap joint and the second lap joint, thereby improving the transportation effect. The gap between the hoppers is covered by the buckling of the first lap joint and the second lap joint to prevent the material in the hopper from spilling out of the gap.

[0010] Furthermore, the corner box is fixedly connected to two friction plates on both sides of the two chains, and each of the two ends of the first lap joint is fixedly connected to a friction wheel, each of the friction wheels can contact the friction plate, the surface of each friction wheel and friction plate is rough, and the two ends of each friction plate are bent and tilted upward.

[0011] When the hopper enters the downward conveying range, the friction wheel is rotated by the mutual friction between the friction wheel and the friction plate, thereby driving the second lap joint and the first lap joint to rotate to change the lap joint mode, so that when the hopper moves downward and the lap joint between the front hopper and the rear hopper is separated, the first lap joint and the second lap joint can be easily separated, avoiding the problem of tipping caused by mutual interference between the hoppers.

[0012] Furthermore, a trapezoidal ridge is provided at the rotation axis center portion of each of the first lap joints, a groove corresponding to the ridge on the first lap joint is provided at the rotation axis center portion of each of the second lap joints, and a plurality of magnets are evenly distributed and fixedly provided in the ridge of each of the first lap joints and the groove of the second lap joints.

[0013] By providing ridges and grooves, the first lap joint and the second lap joint are made more secure and stable when fastened together, and by providing magnets, when the ridges enter the grooves for fastening, the magnetic attraction between the magnets is used to guide the fastening process, thereby ensuring accurate fastening, and after fastening, the magnetic attraction between the magnets is used to ensure that the shape of the first lap joint and the second lap joint after fastening is a complete cylinder, thereby ensuring smooth rotation of the first lap joint and the second lap joint.

[0014] Furthermore, a limited end is arranged at the edge of each of the first lap joint and the second lap joint, and a plurality of balls are evenly distributed on one side of each of the mounting plates close to the first lap joint and the second lap joint.

[0015] By setting the limit end, the rotation range of the first lap joint and the second lap joint can be limited, and by setting the ball, the friction between the first lap joint and the second lap joint and the mounting plate can be reduced to avoid the problem of excessive friction and inability to rotate.

[0016] Furthermore, each of the chain's bends is meshingly connected to a sprocket, and two motors are fixedly connected to the corresponding positions of the two sprockets on both sides of the corner box, and the power output end of each motor passes through the corner box and is connected to the sprocket transmission.

[0017] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0018] By buckling the first lap joint and the second lap joint, the hoppers are connected as a whole, thereby improving the carrying effect. The gaps between the hoppers are covered by buckling the first lap joint and the second lap joint, thereby preventing materials in the hoppers from spilling out of the gaps.

[0019] The friction wheel is rotated by the mutual friction between the friction wheel and the friction plate, thereby driving the second lap joint and the first lap joint to rotate to change the overlapping mode, so that when the hopper moves downward and the overlapping parts of the front hopper and the rear hopper are separated, the first lap joint and the second lap joint can be easily separated, avoiding the problem of tipping caused by interference between the hoppers.

[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] refer to Figure 1-6 A shaping mechanism for an elevator hopper includes a chain 40, with multiple hoppers 41 evenly distributed and hinged between two chains 40, and a mounting plate 42 fixedly connected to both sides of the opening of each hopper 41. The outer sides of the two mounting plates 42 on each hopper 41 are rotatably connected with a first lap joint 44 and a second lap joint 45 respectively, and the adjacent first lap joints 44 and second lap joints 45 can be interlocked, and arc-shaped slide grooves 48 are provided at both ends of each first lap joint 44 and the second lap joint 45, and a connector 43 fixedly connected to the end of the corresponding mounting plate 42 is slidably connected in each slide groove 48, and a corner box 37 covering the chain 40 and the hopper 41 is provided on the outer sides of the two chains 40.

[0028] refer to Figure 5-6The corner box 37 is located on both sides of the two chains 40 and is fixedly connected to two friction plates 50. Both ends of each first lap joint 44 are fixedly connected to friction wheels 49. Each friction wheel 49 can contact the friction plate 50. The surface of each friction wheel 49 and the friction plate 50 is rough, and both ends of each friction plate 50 are bent and tilted upward.

[0029] refer to Figure 3-6 A trapezoidal ridge is provided at the rotation axis center portion of each first lap joint 44, a groove corresponding to the ridge on the first lap joint 44 is provided at the rotation axis center portion of each second lap joint 45, and a plurality of magnets 46 are evenly distributed and fixedly provided in the ridge of each first lap joint 44 and the groove of the second lap joint 45.

[0030] refer to Figure 1-3 A limited end 51 is provided at the edge of each first lap joint 44 and the second lap joint 45 , and a plurality of balls 47 are evenly distributed on one side of each mounting plate 42 close to the first lap joint 44 and the second lap joint 45 .

[0031] refer to Figure 1-6 The bend of each chain 40 is meshed and connected to a sprocket 39, and two motors 38 are fixedly connected at the corresponding positions of the two sprockets 39 on both sides of the corner box 37. The power output end of each motor 38 passes through the corner box 37 and is connected to the sprocket 39.

[0032] In this embodiment, initially, the patent is installed at the corresponding position of the elevator, and the motor 38 is connected to the power supply. When working, the motor 38 is started, so that the motor 38 drives the chain 40 to operate, thereby driving each hopper 41 to operate to transport the material.

[0033] During the horizontal operation of the hopper to transport materials, the first lap joint 44 of the front hopper is buckled with the second lap joint 45 of the rear hopper, and the first lap joint 44 of the front hopper is pressed on top of the second lap joint 45 of the rear hopper, so that the two hoppers are tightly combined, and the hoppers are connected as a whole, which improves the transportation effect, and the gap between the hoppers is covered by the buckling of the first lap joint 44 and the second lap joint 45 to prevent the material in the hopper from spilling from the gap.

[0034] When the hopper enters the downward conveying range, as the hopper 41 moves, the mutual friction between the friction wheel 49 and the friction plate 50 on the hopper causes the friction wheel 49 to rotate. Since the second lap joint 45 and the first lap joint 44 are buckled into a cylindrical shape at this time, the first lap joint 44 and the second lap joint 45 in the buckled state rotate about the axis of the cylinder, so that the second lap joint 45 is pressed on top of the first lap joint 44 to change the overlapping mode. Therefore, when the hopper moves downward and the overlapping part of the front hopper and the rear hopper is separated, the first lap joint 44 and the second lap joint 45 can be easily separated to avoid the problem of tipping caused by interference between the hoppers.

[0035] By providing ridges and grooves, the first lap joint 44 and the second lap joint 45 are made more secure and stable when fastened together. By providing magnets 46, when the ridges enter the grooves for fastening, the magnetic attraction between the magnets 46 is used to guide the fastening process to ensure accurate fastening. After fastening, the magnetic attraction between the magnets 46 is used to ensure that the first lap joint 44 and the second lap joint 45 are in a complete cylindrical shape after fastening, so as to ensure smooth rotation of the first lap joint 44 and the second lap joint 45.

[0036] By setting the limit end 51, the rotation range of the first lap joint 44 and the second lap joint 45 can be limited, and by setting the ball 47, the friction between the first lap joint 44 and the second lap joint 45 and the mounting plate 42 can be reduced to avoid the problem of excessive friction and inability to rotate.

[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
