[0023] The present utility model will be further described below in conjunction with the accompanying drawings.
[0024] The bucket wheel reclaimer is a high - efficiency loading and unloading machine for continuous conveying that can both stack and reclaim materials in large dry bulk cargo yards. The existing bucket wheel reclaimer includes a bucket wheel mechanism, and a hopper for containing materials is arranged on the bucket wheel mechanism. However, during the operation of the bucket wheel reclaimer, materials are likely to remain at the bottom of the hopper of the bucket wheel mechanism. If the remaining materials accumulate for a long time, they will become caked, and manual cleaning at regular intervals is required, which affects maintenance and operation. At the same time, due to the frequent caking of materials at the bottom of the hopper, the rotation speed of the bucket wheel is uneven, and faults such as overload are likely to occur during operation.
[0025] The present utility model provides a hopper mechanism and a bucket wheel reclaimer of a bucket wheel reclaimer, which can effectively prevent the materials at the bottom of the hopper from caking, and avoid faults such as uneven rotation speed of the bucket wheel and overload caused by the caking of materials at the bottom of the hopper during operation.
[0026] Figure 1 It is a schematic view of the structure of the bucket wheel mechanism of the bucket wheel reclaimer in an embodiment of the present utility model; Figure 2 It is a schematic view of the structure of the hopper in an embodiment of the present utility model; Figure 3 It is a schematic view of the hopper from another perspective in an embodiment of the present utility model. As Figures 1 - 3As shown in the figure, an embodiment of the present application provides a bucket wheel mechanism 100 of a bucket wheel stacker-reclaimer. The bucket wheel mechanism 100 includes a hopper 10 and a bucket wheel body 20. The hopper 10 includes a receiving chamber for containing materials and a bottom plate 11 for forming the wall portion of the receiving chamber. The receiving chamber has an opening, and the opening includes a feed port K1 facing the first direction X and a discharge port K2 facing the second direction Y, and the first direction X and the second direction Y intersect. The hopper 10 is installed on the circumferential surface of the bucket wheel body 20, and the discharge port K2 is buckled on the outer wall of the bucket wheel body 20. Among them, a plurality of first through holes T1 are provided on the bottom plate 11.
[0027] It should be noted that the bottom plate 11 of the hopper 10 can be a folded plate bent radially toward the bucket wheel body 20 or an arc-shaped plate bent radially toward the bucket wheel body 20.
[0028] It should be noted that the shape of the first through hole T1 can be circular, diamond-shaped, oval, polygonal or other irregular shapes, etc., which are not limited here. Of course, the specific shape and size of the first through hole T1 can be set according to the materials that the hopper 10 needs to contain.
[0029] According to the bucket wheel mechanism 100 of the bucket wheel stacker-reclaimer provided by the embodiment of the present utility model, the hopper 10 installed on the outer wall of the bucket wheel body 20 shovels materials into the receiving chamber through the feed port K1, and the rotation of the bucket wheel body 20 causes the materials loaded into the hopper 10 to be output through the discharge port K2. Since a plurality of first through holes T1 are provided on the bottom plate 11, when the bucket wheel body 20 drives the hopper 10 to rotate and the materials are shoveled in through the feed port K1 and sent out through the discharge port K2, part of the materials close to the bottom plate 11 can leak out through the first through holes T1, effectively preventing the materials at the bottom of the hopper 10 from caking, and avoiding failures such as uneven bucket wheel speed and overload caused by the caking of materials at the bottom of the hopper 10 during the operation process.
[0030] As Figure 1 shown, in some embodiments, the distance from the feed port K1 along the radial direction of the bucket wheel body 20 to the outer wall of the bucket wheel body 20 is d1, and the distance from the end of the bottom plate 11 away from the feed port K1 along the radial direction of the bucket wheel body 20 to the outer wall of the bucket wheel body 20 is d2, where d1 is greater than d2, so that the cross-sectional area of the hopper 10 in the radial direction of the bucket wheel body 20 gradually increases from the end of the bottom plate 11 away from the feed port K1 to the end of the bottom plate 11 close to the feed port K1, making it easier for the hopper 10 to shovel materials through the feed port K1.
[0031] In some embodiments, the second plate member 112 is a rigid plate or a flexible plate. In this embodiment, when the second plate member 112 is a rigid plate, it can be a metal plate, a plastic plate or a plate formed by welding rigid metal strips. When the second plate member 112 is a flexible plate, it can be made of metal chains, nylon ropes, etc.
[0032] In some other alternative embodiments, a plurality of first openings corresponding to the discharge ports K2 of the hopper 10 body are circumferentially provided on the outer wall of the bucket wheel body 20, and the materials entering the accommodation chamber from the feed port K1 of the hopper 10 are output from the discharge port K2 and the first openings corresponding to the discharge port K2.
[0033] As Figures 2 - 3 shown, in some embodiments, the bottom plate 11 includes a folded plate that is radially bent toward the bucket wheel body 20, and the folded plate includes a first plate member 111, a second plate member 112, and a third plate member 113. Among them, a plurality of first through holes T1 are provided in the first plate member 111 and / or the second plate member 112.
[0034] It should be noted that one end of the third plate member 113 is the end for defining the feed port K1. During the process of stacking and reclaiming materials by the bucket wheel mechanism 100 of the bucket wheel stacker-reclaimer, the third plate member 113 is mainly used to mix materials from the feed port K1 into the accommodation chamber. During the shoveling process, there is a lot of friction between the third plate member 113 and the materials, which is easy to wear. Therefore, it is necessary to ensure the thickness, stiffness, and bearing strength of the third plate member 113. Therefore, in this embodiment, the first through holes T1 are provided in at least one of the first plate member 111 and the second plate member 112, the first plate member 111, and the second plate member 112.
[0035] In this embodiment, a plurality of first through holes T1 are provided in at least one of the first plate member 111 and the second plate member 112, the first plate member 111, and the second plate member 112. When the materials shoveled into the accommodation chamber of the hopper 10 are output from the discharge port K2, some of the materials located at the bottom of the accommodation chamber can leak out through the first through holes T1 provided in the first plate member 111 and / or the second plate member 112, avoiding the materials at the bottom of the hopper 10 from caking on the bottom plate 11 of the accommodation chamber of the hopper 10.
[0036] As Figures 2 - 3 shown, in some embodiments, the first plate member 111, the second plate member 112, and the third plate member 113 are of an integral structure, and the integral structure improves the overall stiffness and bearing capacity of the bottom plate 11. In some other alternative embodiments, it may also be that only the first plate member 111 and the second plate member 112 are of an integral structure or the second plate member 112 and the third plate member 113 are of an integral structure, so that during the manufacturing process of the bottom plate 11, only the first plate member 111 and the second plate member 112 or the second plate member 112 and the third plate member 113 need to be bent relative to each other for convenient processing and manufacturing. At the same time, the integral structure improves the connection strength between the second plate member 112 and the third plate member 113.
[0037] In some embodiments, there is a first included angle between the first plate member 111 and the second plate member 112, and a second included angle between the second plate member 112 and the third plate member 113. The value range of the first included angle is 80° - 100° and / or the value range of the second included angle is 145° - 165°.
[0038] In this embodiment, the included angle between the first plate member 111 and the second plate member 112 ranges from 80° to 100°, and preferably, the included angle between the first plate member 111 and the second plate member 112 is 85°.
[0039] In some alternative embodiments, the included angle between the second plate member 112 and the third plate member 113 ranges from 145° to 165°, and preferably it is 155°.
[0040] As Figure 2 shown, in some embodiments, a plurality of first through holes T1 are equally spaced in the second direction Y and the third direction Z to facilitate the processing and manufacturing of the first through holes T1.
[0041] In some embodiments, the bottom plate 11 includes an arc-shaped plate that is radially bent towards the bucket wheel body 20.
[0042] In this embodiment, the bottom plate 11 includes an arc-shaped plate that is radially bent. The curvature of the arc-shaped plate is smaller than the curvature of the outer wall of the bucket wheel body 20, so that it is easier for the hopper 10 to shovel materials into the feeding port K1. At the same time, the shoveled materials can be more evenly distributed, rather than concentrated in a local area of the bottom plate 11, avoiding the situation where the materials are not completely discharged due to local material concentration on the bottom plate 11 and the materials are stuck on the bottom plate 11.
[0043] As Figure 2 shown, in some embodiments, a plurality of first through holes T1 are provided on the second plate member 112, and the plurality of first through holes T1 are equally spaced along the first direction X and the third direction Z. Symmetrically arranged chutes are provided on two opposite sides of the second plate member 112, and the chutes are arranged on the side of the second plate member 112 away from the accommodating chamber. The hopper 10 further includes an adjusting plate that is slidably arranged in the chutes. The adjusting plate is provided with second through holes corresponding one by one to those on the second plate member 112, and the adjusting plate can make the first through holes T1 and the second through holes misaligned.
[0044] In this embodiment, the adjusting plate is stacked and slidably arranged with the second plate member 112 through the chutes provided on the second plate member 112. By sliding the adjusting plate on the side of the second plate member 112 away from the accommodating chamber, the first through holes T1 on the second plate member 112 can be misaligned with the second through holes on the adjusting plate, thereby changing the discharge amount of the first through holes T1, so that the hopper 10 can flexibly set the discharge amount of the first through holes T1 according to the materials to be filled.
[0045] In some embodiments, the adjustment plate is provided with a strip hole arranged along the length direction of the slide groove, and a connecting shaft is provided on the side of the second plate 112 facing away from the accommodating chamber. The connecting shaft is slidably matched with the strip hole, and the adjustment plate slides along the direction of the slide groove to one end of the strip hole, the first through hole T1 is aligned with the second through hole, and the adjustment plate slides along the length direction of the slide groove to the other end of the strip hole, and the adjustment plate blocks the first through hole T1.
[0046] It should be noted that the adjustment plate is provided with a strip hole arranged along the length direction of the slide slot. It can be understood that the length direction of the strip hole is consistent with the length direction of the slide slot.
[0047] In this embodiment, the connecting shaft provided on the side of the second plate 112 away from the accommodating chamber cooperates with the strip hole provided on the adjustment plate, so that the adjustment plate is limited by the strip hole when sliding relative to the second plate 112 through the slide groove. When the adjustment plate slides until the connecting shaft abuts against both ends of the strip hole along its own length direction, the second through hole provided on the corresponding adjustment plate and the first through hole T1 of the second plate 112 are aligned and the first through hole T1 provided on the adjustment plate and the first through hole T1 on the second plate 112 are completely misaligned, and the adjustment plate blocks the first through hole T1 of the second plate 112.
[0048] like Figures 2 - 3 As shown, in some embodiments, the hopper 10 further includes a side plate 12 for forming a containing cavity, and one end of the side plate 12 is an arc-shaped end for defining a discharge port K2.
[0049] In this embodiment, one of the ends of the side plate 12 is an arc-shaped end portion for defining the discharge port K2, and the arc-shaped end portion is connected to the outer wall of the bucket wheel body 20. The curvature of the arc-shaped end portion is the same as the curvature of the outer wall of the bucket wheel body 20, making the assembly of the hopper 10 and the bucket wheel body 20 more convenient.
[0050] The present invention also provides a bucket wheel stacker and reclaimer, including a bucket wheel mechanism 100 of the bucket wheel stacker and reclaimer of any of the aforementioned implementation modes of the present application, and having all the beneficial effects of the bucket wheel mechanism 100 in any of the aforementioned implementation modes, which will not be described one by one here.
[0051] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
