Description

Technical Field

[0001] This utility model relates to the field of bucket wheel machine technology, specifically to a novel reclaiming bucket wheel 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, capable of both stacking and reclaiming materials. It consists of a belt conveyor arm that can tilt and swing horizontally, along with bucket wheels at its front end, a frame, and a running mechanism. The belt can run in both directions. During reclaiming, materials are picked up by the bucket wheels and conveyed out via the conveyor arm; during stacking, goods transported by the main conveyor are thrown into the yard via the conveyor arm. The bucket wheel is the core component of the stacker-reclaimer, primarily used for material stacking and reclaiming operations. The bucket wheel consists of multiple buckets evenly distributed on a hub, which is driven by a drive unit to rotate, thereby achieving material digging and unloading. However, existing bucket wheels still have the following inconveniences in use:

[0003] 1. The buckets on existing bucket wheels generally lack protective devices. After prolonged use, the contact surface between the bucket and the material is prone to wear, resulting in a reduced service life of the bucket.

[0004] 2. When the bucket on the existing bucket wheel encounters sticky materials, it is easy for material to accumulate. However, due to the problem of the bucket structure, the cleaning work is inconvenient and the efficiency of cleaning up the accumulated material is low. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of bucket wheel for a bucket wheel stacker-reclaimer. An outer protective plate is provided on the contact surface between the bucket and the material to reduce the wear of the bucket, and an inner protective plate is added inside the bucket to facilitate disassembly and cleaning.

[0006] The technical solution adopted in this utility model is a novel bucket wheel for a bucket wheel stacker-reclaimer, including a bucket body. A base plate is fixed at the bottom corner inside the bucket body. The base plate is fixedly connected to an inner protective plate by fastening bolts. Handles are fixed on the inner sidewalls of both the upper and lower ends of the inner protective plate. The outer side of the bucket body is fixedly connected to an I-shaped arc plate by fixing screws and fixing nuts. A guide plate is connected to the front end of the I-shaped arc plate. Rotating wheels are provided in the recessed grooves on both sides of the I-shaped arc plate. A fixed shaft is inserted into the middle of the rotating wheel. One end of a side support rod is connected to the outer end of the fixed shaft. The other end of the side support rod is fixed to an outer protective plate. An outer plate is fixedly connected to the outer side of the side support rod. Side connecting plates are fixed on both sides of the bottom end of the outer plate. Scrapers are fixed at both the upper and lower ends of the other side of the side connecting plate. A fixed plate is connected to the bottom end of the outer protective plate by a spring and a telescopic rod. The fixed plate is fixed to the bottom end of the I-shaped arc plate. An arc plate is connected to the top end of the outer protective plate. Bucket teeth are fixed on the arc plate.

[0007] The I-shaped arc plate is provided with screw holes, and above the screw holes is a screw cap hole. The screw holes are threaded to connect and fix screws, and the screw cap hole contains a cap on the top of the screw.

[0008] The outer side wall of the bucket body is provided with the same screw holes, and the screws are also threaded into them.

[0009] The base plate is provided with bolt holes, and the bolt holes are threaded to connect fastening bolts.

[0010] The inner protective plate has the same bolt holes at the bottom, and fastening bolts are also threaded into them. A limiting groove is provided on one side of the back of the inner protective plate, and the bottom of the fixing nut and fixing screw are inserted into the limiting groove.

[0011] The side connecting plate extends into the recessed grooves on both sides of the I-shaped arc plate, and its height is the same as the height of the recessed grooves. There are also scrapers in the recessed grooves on both sides of the I-shaped arc plate, and the curvature of the scrapers is the same as the curvature of the I-shaped arc plate.

[0012] The bottom end of the rebound spring is fixed to the telescopic rod, and the telescopic end of the telescopic rod passes through it.

[0013] The beneficial effects of this utility model are as follows: In this utility model, an I-shaped arc plate is fixed on the outer side wall of the bucket body, and an outer protective plate is provided above the I-shaped arc plate. The outer protective plate can slide on the I-shaped arc plate under the combined action of the side support rod, the fixed shaft, and the rotating wheel. When the bucket body is in operation, the outer protective plate will come into contact with the material, which solves the problem that the bucket body is prone to wear due to long-term frictional contact with the material.

[0014] In this utility model, a bottom plate is fixed inside the bucket body. The bottom plate is fixed to the inner protective plate by fastening bolts. When there is a lot of material accumulated on the inner protective plate, the inner protective plate can be removed simply by tightening the fastening bolts, which facilitates the cleaning of the material accumulated on the inner protective plate and improves the efficiency of material cleaning.

[0015] In this invention, a rebound spring and a telescopic rod are provided at the bottom of the outer protective plate. When the outer protective plate slides downward, the rebound spring and the telescopic rod can provide a certain shock absorption and rebound force for the outer protective plate, which can extend the service life of the outer protective plate and facilitate the automatic reset of the outer protective plate.

[0016] In this invention, scrapers are provided in the recessed grooves on both sides of the I-shaped arc plate, which can remove the material in the recessed grooves on both sides of the I-shaped arc plate, making it easier for the rotating wheel to rotate. Attached Figure Description
