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.

[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 shortcomings of the prior art, the present invention solves the technical problem that, during the process of the hopper conveying materials, the hoppers are connected as a whole through the buckling between the lap joint and the lap block, thereby improving the carrying effect and shielding the gap between the hoppers to prevent materials from spilling from the gap between the hoppers. When the hopper enters the downward conveying range, the lap block flips to form a gap, so that the rod head of the lap joint can pass smoothly, thereby effectively avoiding mutual interference between the hoppers and causing the hopper to tip over. When the lap block is separated from the lap joint, the sliding connection between the slide bar guide rail and the slide bar is utilized to automatically drive the lap block to flip while keeping the hopper in a stable state, thereby preventing the hopper from tilting and causing material to spill.

[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 connecting rods evenly distributed and hinged between two of the chains, a bucket fixedly connected between every two opposite connecting rods, a lap joint with a plurality of rod heads fixedly connected to one side of the opening edge of each of the hoppers, a group of lap blocks that can be snapped with the rod heads of the corresponding lap joints are rotatably connected to the side of each of the hoppers away from the lap joint, each of the lap blocks is provided with grooves matching the shape of the lap joint rod heads at both ends, and the ends of two adjacent lap blocks in each group of lap blocks overlap each other when snapped together, and a corner box covering the chain and the bucket is provided on the outside of the chain.

[0009] During the process of the hopper conveying materials, the hoppers are connected as a whole through the buckling between the lap joints and the lap blocks, thereby improving the carrying effect and covering the gaps between the hoppers to prevent materials from spilling from the gaps between the hoppers.

[0010] Moreover, when the hopper enters the downward conveying range, the overlap block flips to form a gap, so that the rod head of the overlap joint can pass smoothly, which effectively avoids the problem of interference between the hoppers and causing the hopper to tip over.

[0011] Furthermore, a rocker arm is fixedly connected to the bottom of each overlapping block, a slide groove is opened at the bottom end of each rocker arm, a group of guide plates are fixedly connected to the side of each hopper close to the overlapping block, a slide rod is slidably connected between each group of guide plates, a plurality of sliding pins are evenly distributed on each slide rod, each sliding pin is slidably connected to the corresponding slide groove, and a slide rod guide rail is fixedly connected to the side of the corner box body close to the end of the slide rod extending out of the guide plate, and the slide rod guide rail can be slidably connected to the end of the slide rod extending out of the guide plate.

[0012] When the overlap block is separated from the overlap joint, the sliding connection between the slide bar guide rail and the slide bar is utilized to automatically drive the overlap block to flip while keeping the hopper in a stable state at all times, thereby preventing the hopper from tilting and causing the material to spill.

[0013] Furthermore, the corner box is symmetrically distributed and fixedly connected to two chain guides on both sides of the chain bending part, each of the chain guides is slidably connected to the chain bending part, and two motors are fixedly connected to the two sides of the two chain guides away from each other, and the output end of each motor is transmission-connected to a sprocket that is meshing and transmission-connected to the corresponding chain.

[0014] By setting the chain guide rail, the radius of the bending area of ​​the chain is made larger, so that the process of the hopper changing from horizontal movement to vertical movement is smoother, and the process of separation of the overlap joint and the overlap block is smoother, thereby improving the conveying effect of the elevator.

[0015] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0016] The hoppers are connected as a whole by the buckling between the lap joints and the lap blocks, thereby improving the carrying effect and shielding the gaps between the hoppers to prevent materials from spilling from the gaps between the hoppers.

[0017] When the hopper enters the downward conveying range, the overlap block flips to form a gap, so that the rod head of the overlap joint can pass smoothly, which effectively avoids the interference between hoppers and causes the hopper to tip over.

[0018] When the overlap block is separated from the overlap joint, the sliding connection between the slide bar guide rail and the slide bar is utilized to automatically drive the overlap block to flip while keeping the hopper in a stable state at all times, thereby preventing the hopper from tilting and causing the material to spill.

[0019] By setting the chain guide rail, the radius of the bending area of ​​the chain is made larger, so that the process of the hopper changing from horizontal movement to vertical movement is smoother, and the process of separation of the overlap joint and the overlap block is smoother, thereby improving the conveying effect of the elevator.

[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 bucket includes a chain 25, a plurality of connecting rods 29 evenly distributed and hinged between two chains 25, a bucket 30 is fixedly connected between every two opposite connecting rods 29, a lap joint 31 with a plurality of rod heads is fixedly connected to one side of the opening edge of each hopper 30, a group of lap blocks 32 that can be buckled with the rod heads of the corresponding lap joints 31 are rotatably connected to the side of each hopper 30 away from the lap joint 31, each lap block 32 has grooves at both ends that match the shape of the rod heads of the lap joint 31, and the ends of two adjacent lap blocks 32 of each group of lap blocks 32 overlap each other when buckled, and a corner box 24 covering the chain 25 and the hopper 30 is provided on the outside of the chain 25.

[0028] During the process of the hopper conveying materials, the hoppers are connected as a whole through the buckling between the lap joint 31 and the lap block 32, thereby improving the carrying effect and shielding the gap between the hoppers to prevent materials from spilling from the gap between the hoppers.

[0029] Furthermore, when the hopper enters the downward conveying range, the overlap block 32 is turned over to form a gap, so that the rod head of the overlap joint 31 can pass smoothly, which effectively avoids the problem of interference between hoppers and causing the hopper to tip over.

[0030] refer to Figure 4-6 A rocker arm 33 is fixedly connected to the bottom of each overlapping block 32, and a slide groove 52 is opened at the bottom end of each rocker arm 33. A group of guide plates 34 are fixedly connected to the side of each hopper 30 close to the overlapping block 32, and a slide rod 35 is slidably connected between each group of guide plates 34. A plurality of sliding pins 53 are evenly distributed on each slide rod 35, and each sliding pin 53 is slidably connected to the corresponding slide groove 52. A slide rod guide rail 36 is fixedly connected to the side of the corner box body 24 close to the end of the slide rod 35 extending out of the guide plate 34, and the slide rod guide rail 36 can be slidably connected to the end of the slide rod 35 extending out of the guide plate 34.

[0031] When the overlap block 32 is separated from the overlap joint 31, the sliding connection between the slide bar guide rail 36 and the slide bar 35 is utilized to automatically drive the overlap block 32 to flip while keeping the hopper in a stable state at all times, thereby preventing the hopper from tilting and causing the material to spill.

[0032] refer to Figure 1-4 The corner box 24 is symmetrically distributed and fixedly connected to two chain guides 26 on both sides of the bent part of the chain 25. Each chain guide 26 is slidably connected to the bent part of the chain 25. Two motors 28 are fixedly connected to the two sides of the two chain guides 26 away from each other. The output end of each motor 28 is transmission-connected to a sprocket 27 that meshes and transmission-connected with the corresponding chain 25.

[0033] In this embodiment, initially, the patent is installed at the corresponding position of the elevator, and the motor 28 is connected to the power supply. When working, the motor 28 is started, so that the motor 28 drives the chain 25 to operate, thereby driving each hopper 30 to operate to transport the material.

[0034] When the hopper 30 is conveying materials horizontally, all the rocker arms 33 are in a vertical state, and the multiple overlap blocks 32 of the front hopper overlap each other, and cover and buckle the rod head of the rear overlap joint 31, so that the hoppers are tightly combined, greatly improving the carrying capacity of the hoppers, and the gap between the two hoppers is covered by the overlap block 32 to prevent materials from spilling from the gap between the hoppers.

[0035] When the hopper needs to change from horizontal conveying to vertical conveying, the slide bar 35 on the front hopper first slides into the slide bar guide rail 36, and as the chain 25 continues to drive the hopper 30 to move, the end of the slide bar 35 contacts and slides with the inclined surface of the slide bar guide rail 36, thereby pushing the slide bar 35 to the other end. At this time, due to the sliding connection between the sliding pin 53 and the slide groove 52, the multiple rocker arms 33 on the front hopper 30 tilt and drive the overlapping block 32 to flip, and disengage from the overlapping joint 31 on the rear hopper 30, and form a vertical gap between the overlapping blocks 32 and the overlapping blocks 32.

[0036] The chain 25 continues to drive the hopper 30 to move, so that the hopper 30 gradually enters the bending area of ​​the chain 25, and the hopper 30 begins to gradually move downward, and a height difference gradually occurs between the front hopper 30 and the rear hopper 30, and the rod head part of the rear lap joint 31 will gradually detach from the gap formed between the lap blocks 32, thereby changing the lap mode between the hoppers and avoiding the problem of dumping caused by interference between the hoppers.

[0037] As the hopper 30 gradually moves downward, the slide bar 35 is always in the slide bar guide rail 36, and the slide bar guide rail 36 has the same trajectory shape as the chain 25. The slide bar 35 automatically drives the overlap block 32 to flip while keeping the hopper in a stable state to prevent the hopper from tilting and causing material to spill.

[0038] By providing the chain guide rail 26, the radius of the bending area of ​​the chain 25 is made larger, so that the process of the hopper changing from horizontal movement to vertical movement is smoother, and the process of separation of the overlap joint 31 and the overlap block 32 is smoother, thereby improving the conveying effect of the elevator.
