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-mentioned 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, and the overlapping edge of the front hopper is pressed down, and the rear hopper is reset under the action of gravity, thereby changing the overlapping mode and avoiding interference between the overlapping edges when the hoppers move down, causing the hoppers to tip over. However, in the process of changing the overlapping mode, the overlapping edges will collide and rub against each other, and after long-term use, the overlapping edges will be damaged and deformed, affecting the service life. In addition, in the process of changing the overlapping mode, the rear hopper will be tilted, which will make it easier for the material in the hopper to spill, affecting the conveying effect.

[0006] In the above patent, after the hopper enters the vertical movement range, the hopper cannot be restricted. When the center distribution of the material in the hopper is uneven, or under the mechanical vibration of the elevator, the hopper is prone to tilt or tip over, causing the material in the hopper to spill and affect the conveying effect. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the present invention solves the technical problem of making the chain first tilt upward and then run downward according to its running direction, thereby avoiding contact between the overlapping edges in the process of tilting the hopper to change the overlapping mode of the overlapping edges, thereby avoiding the problem of friction between the overlapping edges affecting the service life, and by arranging supporting feet, the hopper is automatically tilted when it contacts the guide belt to change the position of the overlapping edge, and in the process of the hopper moving downward, the guide belt always supports the hopper and limits the rotation of the hopper to ensure the stability of the hopper moving downward process and avoid spilling of materials.

[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, wherein the upper end of the chain is first tilted upward according to its running direction, the chain is bent at the top and vertically downward, the overlapping edge and the support leg on the bucket located on the vertical part of the chain are against the surface of the guide component, a plurality of buckets are evenly distributed and hinged between the two chains, an overlapping edge is provided at the edge of the upper end of each bucket, two adjacent overlapping edges are overlapped with each other, and support legs are symmetrically distributed and fixedly connected on the inclined surfaces on both sides of each bucket, two side plates are provided on the two sides of the two chains away from each other, and a box covering the chain, the bucket and the guide component is fixedly connected between the two side plates.

[0009] By making the chain tilt upward first and then run downward according to its running direction, contact between overlapping edges can be avoided in the process of tilting the hopper to change the overlapping mode of overlapping edges, thereby avoiding the problem of collision and friction between overlapping edges affecting service life.

[0010] Furthermore, two pulleys are rotatably connected between the two side plates, a vertical guide belt is transmission-connected between the two pulleys, a rotating shaft portion of one of the pulleys extends out of the side plate and is transmission-connected to a first motor, a support plate is fixedly connected to the inner side of the guide belt between the two side plates, and the side surface of the support plate is tightly fitted with a side of the guide belt close to the chain and slides relative to it.

[0011] When the hopper contacts the guide belt, the overlapping edge and the supporting feet of the hopper edge rest against the surface of the guide belt and tilt automatically to change the position of the overlapping edge. During the downward movement of the hopper, the guide belt always supports the hopper and limits the rotation of the hopper to ensure the stability of the hopper's downward movement and avoid spilling of materials.

[0012] Furthermore, the inner side of each side plate is located at the top bending part of the chain and is rotatably connected to a transmission sprocket that is meshingly connected to the chain; the inner side of each side plate is located at the bottom bending part of the chain and is rotatably connected to a first guide wheel that is meshingly connected to the chain; the inner side of each side plate is located at the bending part of another chain close to the transmission sprocket and is rotatably connected to a second guide wheel that is meshingly connected to the chain; the outer side of each side plate is located at a corresponding position of the transmission sprocket and is fixedly connected to a second motor that is transmission-connected to the transmission sprocket.

[0013] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0014] By making the chain tilt upward first and then run downward according to its running direction, contact between overlapping edges can be avoided in the process of tilting the hopper to change the overlapping mode of overlapping edges, thereby avoiding the problem of collision and friction between overlapping edges affecting service life.

[0015] When the hopper contacts the guide belt, the overlapping edge and the supporting feet of the hopper edge rest against the surface of the guide belt and tilt automatically to change the position of the overlapping edge. During the downward movement of the hopper, the guide belt always supports the hopper and limits the rotation of the hopper to ensure the stability of the hopper's downward movement and avoid spilling of materials.

[0021] 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.

[0022] refer to Figure 1-5 A shaping mechanism for an elevator bucket includes a chain 14. The upper end of the chain 14 is first tilted upward according to its running direction. The chain 14 is bent at the top and vertically downward. The overlapping edge 16 and the support leg 17 on the bucket 15 located at the vertical part of the chain 14 are against the surface of the guide component. A plurality of buckets 15 are evenly distributed and hinged between the two chains 14. An overlapping edge 16 is provided at the upper edge of each bucket 15. Two adjacent overlapping edges 16 overlap each other. Support legs 17 are symmetrically distributed and fixedly connected on the inclined surfaces on both sides of each bucket 15. Two side plates 11 are provided on the two sides of the two chains 14 away from each other. A box body 10 covering the chain 14, the bucket 15 and the guide component is fixedly connected between the two side plates 11.

[0023] By making the chain 14 tilt upward first and then run downward according to its running direction, contact between overlapping edges can be avoided in the process of tilting the hopper to change the overlapping mode of overlapping edges, thereby avoiding the problem of collision and friction between overlapping edges affecting service life.

[0024] refer to Figure 5 Two pulleys 21 are rotatably connected between the two side plates 11, and a vertical guide belt 23 is transmission-connected between the two pulleys 21. The rotating shaft portion of one pulley 21 extends out of the side plate 11 and is transmission-connected to the first motor 12. A support plate 22 is fixedly connected to the inner side of the guide belt 23 between the two side plates 11, and the side surface of the support plate 22 is tightly fitted with a side of the guide belt 23 close to the chain 14 and slides relative to each other.

[0025] When the hopper contacts the guide belt 23, the overlapping edge 16 and the support foot 17 of the hopper edge rest against the surface of the guide belt 23 and automatically tilt to change the position of the overlapping edge. During the downward movement of the hopper, the guide belt 23 always supports the hopper and limits the rotation of the hopper to ensure the stability of the hopper's downward movement and avoid spilling of materials.

[0026] refer to Figure 2 , 5The inner side of each side plate 11 is located at the top bending part of the chain 14 and is rotatably connected to a transmission sprocket 20 that is meshing and transmission connected to the chain 14. The inner side of each side plate 11 is located at the bottom bending part of the chain 14 and is rotatably connected to a first guide wheel 18 that is meshing and transmission connected to the chain 14. The inner side of each side plate 11 is located at the bending part of another chain 14 close to the transmission sprocket 20 and is rotatably connected to a second guide wheel 19 that is meshing and transmission connected to the chain 14. The outer side of each side plate 11 is located at a corresponding position of the transmission sprocket 20 and is fixedly connected to a second motor 13 that is transmission-connected to the transmission sprocket 20.

[0027] In this embodiment, initially, the operator installs the present invention at the corresponding position of the elevator, and connects the second motor 13 to the first motor 12. When working, the second motor 13 is started to drive the transmission sprocket 20 to rotate, thereby driving the chain 14 to operate and drive all the hoppers 15 to circulate to transport the materials. When the first motor 12 is started, the pulley 21 rotates to drive the guide belt 23 to operate.

[0028] When the hopper 15 moves horizontally to transport materials, the overlapping edges 16 between two adjacent hoppers 15 overlap each other, and the overlapping edge 16 of the front hopper is pressed on the overlapping edge 16 of the rear hopper, thereby covering the gap between the hoppers 15 and preventing the materials in the hoppers from spilling from the gap.

[0029] When the hopper needs to change the conveying direction and move downward, the hopper 15 first moves upward along the upward inclined trajectory of the chain 14, so that the overlapping edge 16 of the front hopper 15 is separated from the overlapping edge 16 of the rear hopper 15, and space is made to allow the front overlapping edge 16 to tilt. When the hopper 15 moves to the top of the chain 14, the overlapping edge 16 and the support foot 17 of the hopper 15 close to the side of the guide belt 23 are against the surface of the guide belt 23, which causes the hopper 15 to tilt, and then the overlapping edge 16 originally pressed on the top of the rear hopper 15 is tilted downward, and the overlapping edge 16 of the rear hopper is avoided.

[0030] When the front hopper 15 is tilted, no contact occurs between the two adjacent hoppers, thereby avoiding collision and friction between the overlapping edges 16, ensuring the service life of the overlapping edges 16

[0031] Then, the hopper 15 in contact with the guide belt 23 moves downward with the operation of the chain 14. After the front hopper 15 is tilted, the front overlapping edge 16 avoids the rear overlapping edge 16. During the downward movement of the front hopper 15, the two overlapping edges 16 that were originally overlapping each other do not contact each other and move up and down alternately, thereby avoiding the problem of interference between the two overlapping edges 16 causing the hopper 15 to dump and spill materials.

[0032] And because the guide belt 23 rotates together, the guide belt 23 always supports the hopper 15 during the downward movement of the hopper 15 to prevent the hopper 15 from shaking and tilting and causing material to spill. When the hopper 15 passes through the area of ​​the first guide wheel 18, it changes from vertical to horizontal operation again. At this time, the hopper 15 is separated from the support of the guide belt 23 and resumes its vertical rotation state under the action of gravity. Since the front hopper 15 becomes horizontal first, the overlapping edge 16 of the rear hopper 15 will be pressed above the overlapping edge 16 of the front hopper 15, and the cycle is repeated.

[0033] 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.
