Description

Technical Field

[0001] This invention relates to the field of stacker-reclaimer technology, and particularly to a bucket wheel retaining device for a bucket wheel stacker-reclaimer. Background Technology

[0002] A bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards for continuous conveying and reclaiming of materials. It consists of a belt conveyor arm that can tilt and swing horizontally, a bucket wheel at its front end, a frame, and a running mechanism. The belt can run in both directions. When reclaiming materials, the bucket wheel picks up the materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveyor arm. The boom-type bucket wheel stacker-reclaimer consists of a bucket wheel device, a slewing mechanism, a belt conveyor, a tail car, and a tilting and running mechanism.

[0003] The bucket wheel device is the working mechanism for material handling, including the bucket wheel and its drive unit. When the bucket wheel device is handling material from the pile, it is often compressed by the material at the top. This not only causes the load on the top material to affect the overall operation of the machine, but also makes it impossible to guide and divert the material at the top for material handling. This is not conducive to the continuous advancement of the bucket wheel device in deep digging, and requires constant adjustment of the pitch angle of the bucket wheel device, which greatly reduces the material handling efficiency and increases the difficulty of operation.

[0004] Therefore, it is necessary to design a bucket wheel retaining device for a bucket wheel stacker-reclaimer to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a bucket wheel retaining device for a bucket wheel stacker-reclaimer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bucket wheel blocking device for a bucket wheel stacker-reclaimer, comprising a blocking device body for blocking material from the bucket wheel of the stacker-reclaimer, the blocking device body including a material guiding frame, and a first material guide frame and a second material guide frame respectively fixedly installed on both sides of the material guiding frame, while the bucket wheel device body is movably installed inside the material guiding frame, and the bucket wheel device body including a bucket wheel body, a baffle fixedly installed on one end face of the bucket wheel body, and a transmission mechanism provided on the end face of the bucket wheel body away from the baffle.

At the same time, a tapered rod is fixedly installed at the bottom of the support disc. A closing plate is fixedly installed on one end face of the material diversion baffle, and the closing plate and the cantilever belt conveyor frame are fixedly connected by fixing bolts. The material diversion baffle is arranged in an arch shape.

[0008] As a preferred embodiment of the present invention, the inner bottom ends of the first material guide frame and the second material guide frame are fixedly connected to the material diversion baffle by a support connecting rod, and a triangular reinforcing bracket is fixedly installed between the support connecting rod and the support disc. At the same time, the first material guide frame and the second material guide frame are both arranged in an acute triangle, and the first material guide frame and the second material guide frame are symmetrically distributed on both sides of the material diversion baffle.

[0009] As a preferred embodiment of the present invention, the bucket wheel body includes a wheel body, with buckets distributed in a ring around the outer surface of the wheel body, and a fan-shaped inclined groove is provided on one end face of the wheel body.

[0010] As a preferred embodiment of the present invention, a number of sets of equidistant fixed sleeve cleats are fixedly installed on the outer surface of the wheel body, and shovel teeth are fixedly installed at the opening of the bucket. A limiting fixed sleeve is fitted on the outer surface of the bucket near the opening. At the same time, the limiting fixed sleeve and the fixed sleeve cleats are fixedly connected by screws. Meanwhile, a discharge plate is fixedly installed inside the fan-shaped inclined chute.

[0011] As a preferred embodiment of the present invention, the baffle is mainly composed of an arc-shaped baffle body and a horizontal baffle body, and the arc-shaped baffle body and the horizontal baffle body are integrally formed. A bucket wheel mounting ring is fixedly installed on the outer surface of the arc-shaped baffle body, and a belt conveyor frame mounting ring is fixedly installed at the bottom of the horizontal baffle body.

[0012] In a preferred embodiment of the present invention, the bucket wheel mounting ring and the wheel body, the belt conveyor frame mounting ring and the cantilever belt conveyor frame are all fixedly connected by bolts.

[0013] As a preferred embodiment of the present invention, the transmission mechanism is mainly composed of a drive motor and a bucket wheel shaft, and the drive motor and the bucket wheel shaft are fixedly connected by a coupling, while the bucket wheel shaft and the wheel body are fixedly connected by bolts.

[0014] As a preferred embodiment of the present invention, a bearing seat is fitted on the end of the bucket wheel shaft near the wheel body by bolts, and the bearing seat and the wheel body are fixedly connected by bolts.

[0015] Beneficial Effects: Addressing the issue of bucket wheel devices often being compressed by material at the top during material handling operations, this invention utilizes a material diversion baffle to create a safe space at the top of the material pile. This baffle supports the material at the top as the bucket wheel device advances within the pile, effectively blocking it. Simultaneously, the material at the top slides downwards under its own weight along the top surfaces of the first and second material guide frames, reaching the bottom of the bucket wheel device. The bucket wheel device can then handle this material until it has completely slid down. The material diversion baffle, first material guide frame, and second material guide frame provide a material-blocking mechanism, preventing the bucket wheel device from being compressed by material at the top during material handling, thus avoiding excessive load and impacting overall machine operation. Furthermore, the material at the top is diverted and guided for efficient material handling, facilitating deeper digging without requiring constant adjustments to the bucket wheel device's pitch angle, improving material handling efficiency, and reducing operational difficulty.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figure 1-6 This invention provides a technical solution, which is specifically for use in the material blocking function of a bucket wheel device, as follows:

[0028] An embodiment of a bucket wheel stacker-reclaimer includes a main body 1 for blocking material from the bucket wheel of the stacker-reclaimer. The main body 1 includes a material guide frame 2, and a first material guide frame 3 and a second material guide frame 4 are fixedly installed on both sides of the material guide frame 2. The main body 5 of the bucket wheel device is movably installed inside the material guide frame 2. The main body 5 of the bucket wheel device includes a bucket wheel body 6. A baffle 7 is fixedly installed on one end face of the bucket wheel body 6, and a transmission mechanism 8 is provided on the end face of the bucket wheel body 6 away from the baffle 7.

[0029] During operation, the drive motor 81 starts working, causing the bucket wheel shaft 82 and wheel body 61 to rotate continuously, which in turn causes the bucket 62 to continuously pick up material. Simultaneously, the material is discharged onto a conveyor belt via the unloading plate 631 inside the fan-shaped inclined chute 63, and then transported to the tail car by a cantilever belt conveyor. During the operation of the bucket wheel device body 5, the material guide baffle 2 creates a safe space above it and supports the material on top as the bucket wheel device body 5 continuously excavates within the material pile, achieving a material blocking effect. At the same time, the material on top slides downwards under its own gravity along the material guide baffle 2, and along the first material... The top surfaces of the guide frame 3 and the second material guide frame 4 continuously slide down to the bottom of the bucket wheel device body 5. At this point, the bucket wheel device body 5 can pick up material from it until the material on top has completely slid down. The material diversion baffle 2, the first material guide frame 3, and the second material guide frame 4 provide a material blocking device for the bucket wheel. On the one hand, this prevents the bucket wheel device body 5 from being compressed by the material on top during material pile excavation, which would cause a load that would affect the overall machine operation. On the other hand, it can guide and divert the material on top to achieve material picking, which is conducive to the continuous advancement of the bucket wheel device body 5 in deep digging. There is no need to constantly adjust the pitch angle of the bucket wheel device body 5, which improves the material picking efficiency and reduces the difficulty of operation.

[0030] In the above embodiments, the corresponding component positions are as follows:

[0031] The specific component locations and connection relationships of the material diversion baffle 2 are as follows.

[0032] Please refer to Figure 2The material diversion baffle 2 has load-bearing columns 21 fixedly installed at the four corners of its bottom, and a support disc 22 fixedly installed at the bottom of the load-bearing column 21. At the same time, a tapered insert rod 23 is fixedly installed at the bottom of the support disc 22. A closing plate 24 is fixedly installed on one end face of the material diversion baffle 2, and the closing plate 24 and the cantilever belt conveyor frame are fixedly connected by fixing bolts 25. The material diversion baffle 2 is arched, and the load-bearing columns 21 and the support disc 22 allow the material diversion baffle 2 to contact the ground and be supported by the ground, thereby greatly reducing the burden of the material diversion baffle 2 on the cantilever belt conveyor. The tapered insert rod 23 makes it easier to insert the load-bearing column 21.

[0033] The specific component locations and connection relationships of the first material guide frame 3 and the second material guide frame 4 are as follows.

[0034] Please refer to Figure 2 The bottom of the first material guide frame 3 and the second material guide frame 4 are fixedly connected to the material diversion baffle 2 by a support connecting rod 341. A triangular reinforcing bracket 342 is fixedly installed between the support connecting rod 341 and the support disc 22. The first material guide frame 3 and the second material guide frame 4 are both arranged in an acute triangle. At the same time, the first material guide frame 3 and the second material guide frame 4 are symmetrically distributed on both sides of the material diversion baffle 2. The structure of the support connecting rod 341 and the reinforcing bracket 342 makes the first material guide frame 3 and the second material guide frame 4 have strong stability, ensuring the stability and reliability of diversion.

[0035] The specific locations of the components of the bucket wheel body 6 and their connection relationships are as follows.

[0036] Please refer to Figure 3 as well as Figure 4 The bucket wheel body 6 includes a wheel body 61, with buckets 62 arranged in a ring around the outer surface of the wheel body 61. A fan-shaped inclined chute 63 is provided on one end face of the wheel body 61. Several sets of equidistant fixed sleeve lugs 611 are fixedly installed on the outer surface of the wheel body 61. Shovel teeth 621 are fixedly installed at the opening of the bucket 62. A limiting fixed sleeve 622 is fitted on the outer surface of the bucket 62 near the opening. The limiting fixed sleeve 622 and the fixed sleeve lugs 611 are fixedly connected by screws 623. Meanwhile, a discharge plate 631 is fixedly installed inside the fan-shaped inclined chute 63. The structure of the fixed sleeve lugs 611, the limiting fixed sleeve 622, and the screws 623 can reinforce the bucket 62 and the wheel body 61, thereby greatly reducing the wear and tear on the bucket 62 during operation and extending its service life.

[0037] The specific component locations and connection relationships of baffle 7 are as follows.

[0038] Please refer to Figure 3 as well as Figure 5 The baffle 7 is mainly composed of an arc-shaped baffle body 71 and a horizontal baffle body 72, which are integrally formed. A bucket wheel mounting ring 711 is fixedly installed on the outer surface of the arc-shaped baffle body 71, and a belt conveyor frame mounting ring 721 is fixedly installed at the bottom of the horizontal baffle body 72. The bucket wheel mounting ring 711 and the wheel body 61, the belt conveyor frame mounting ring 721 and the cantilever belt conveyor frame are all fixedly connected by bolts. The baffle 7, which is composed of the arc-shaped baffle body 71 and the horizontal baffle body 72, conforms to the shape characteristics of the bucket wheel and the cantilever belt conveyor frame, which is beneficial for material blocking.

[0039] The specific component locations and connection relationships of the transmission mechanism 8 are as follows.

[0040] Please refer to Figure 3 as well as Figure 6 The transmission mechanism 8 is mainly composed of a drive motor 81 and a bucket wheel shaft 82. The drive motor 81 and the bucket wheel shaft 82 are fixedly connected by a coupling 83, and the bucket wheel shaft 82 and the wheel body 61 are fixedly connected by bolts. A motor base 811 is fixedly installed at the bottom of the drive motor 81, and the motor base 811 and the cantilever belt conveyor frame are fixedly connected by bolts. A bearing seat 821 is fitted on the end of the bucket wheel shaft 82 near the wheel body 61, and the bearing seat 821 and the wheel body 61 are fixedly connected by bolts. When the drive motor 81 starts working, the bucket wheel shaft 82 and the wheel body 61 rotate continuously, causing the bucket 62 to continuously pick up material. At the same time, the material is discharged onto the belt through the unloading plate 631 inside the fan-shaped inclined chute 63, and then transported to the tail car by the cantilever belt conveyor.

[0041] In summary, in this invention, the material diversion baffle 2 creates a safe space at the top of the bucket wheel device body 5. As the bucket wheel device body 5 continuously digs within the material pile, it supports the material at the top, achieving a material-blocking effect. Simultaneously, the material at the top slides downwards under its own gravity along the material diversion baffle 2 and continuously slides down the top surfaces of the first material guide frame 3 and the second material guide frame 4 until it reaches the bottom of the bucket wheel device body 5. At this point, the bucket wheel device body 5 can pick up the material until the material at the top has completely slid down. The material diversion baffle 2, the first material guide frame 3, and the second material guide frame 4 provide a material-blocking device for the bucket wheel. On the one hand, this prevents the bucket wheel device body 5 from being compressed by the material at the top during digging in the material pile, thus avoiding a heavy load that affects the overall machine operation. On the other hand, it allows for the digging of the material at the top, facilitating continuous advancement of the bucket wheel device body 5 through deep digging. This eliminates the need for constant adjustment of the bucket wheel device body 5's pitch angle, improving material-picking efficiency and reducing operational difficulty.
