Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a mining openable bucket. Background Technology

[0002] In mining operations such as ore extraction and transportation, the bucket, as a core loading component, directly impacts the overall construction progress due to its operational efficiency. Traditional mining buckets are mostly one-piece enclosed structures, relying on the overall tilting of the bucket to discharge material during unloading. This structure has several limitations in practical applications:

[0003] Firstly, for moist, sticky materials (such as clay, sludge, and mixed ores), the material easily adheres to the inner wall of the bucket due to gravity and adsorption, especially in the depths and corners of the bucket, forming stubborn residues. When the material is compacted, the bonding force between the residue and the inner wall is significantly enhanced, making it difficult to completely remove it using conventional tilting unloading methods.

[0004] Secondly, residual material continuously occupies the effective cavity space of the bucket, resulting in a decrease in the amount loaded each time and frequent manual cleaning, which not only increases labor intensity but also seriously affects the continuity of operations. For example, when continuously loading wet ore, the amount of residue inside the bucket can accumulate to 15%-30% of the total volume, significantly reducing loading efficiency.

[0005] In addition, traditional bucket unloading requires a wide range of posture adjustments through the coordination of the boom and stick. In narrow alleys, silos and other spaces, it is difficult to achieve precise unloading, which can easily cause material spillage or unloading position deviation, increasing the workload of subsequent cleanup.

[0006] To address the aforementioned issues, this invention presents an openable bucket that, through the synergistic effect of its split structure and material cleaning components, specifically solves the problem of residue from damp, compacted materials, while simultaneously optimizing unloading flexibility. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a mine-use openable bucket.

[0008] This utility model proposes a mine bucket that can be opened and closed, comprising:

[0009] The front bucket body, located on the material inlet side of the bucket, is a through-type structure that forms the inlet part when shoveling material;

[0010] The rear bucket body, located deep within the bucket, is a bucket-shaped structure with a cavity, forming the material receiving section;

[0011] The tops of the front bucket and the rear bucket are hinged by a pin, allowing the front bucket to rotate relative to the rear bucket around the pin.

[0012] The telescopic cylinder is connected at both ends to the side walls of the front bucket and the rear bucket, respectively.

[0013] The material cleaning assembly includes a vertically moving shovel and a drive mechanism. The shovel is located on the inner wall of the rear bucket, and the drive mechanism is mounted on the rear bucket and is connected to the shovel for driving the shovel to move up and down.

[0014] When the telescopic cylinder is in the retracted state, the front bucket and the rear bucket are closed, forming a complete bucket structure for loading materials; when the telescopic cylinder is in the extended state, the front bucket rotates around the pivot, creating an opening at the hinge between the front and rear buckets for unloading materials.

[0015] Preferably, the drive mechanism includes a lifting cylinder, a fixing frame, and a connecting rod. The lifting cylinder is installed on the outer back side of the rear bucket body, the fixing frame is connected to the top of the cylinder, one end of the connecting rod is connected to the bottom of the fixing frame, and the other end passes through the top side wall of the rear bucket body and is connected to the shovel plate.

[0016] Preferably, one end of the telescopic cylinder is rotatably connected to the side wall of the front bucket, and the other end is rotatably connected to the side wall of the rear bucket.

[0017] Preferably, multiple sets of shovel claws are installed on the front side of the portion of the bucket body that contacts the ground.

[0018] Preferably, the shovel claws are made of high-strength wear-resistant steel, and the distance between adjacent shovel claws is 100-200mm.

[0019] Preferably, a connecting frame is provided on the back of the rear bucket body. The connecting frame is hinged to the boom and stick of the loader via a hinge shaft to realize the assembly of the bucket and the loader and control the lifting and lowering of the bucket.

[0020] Preferably, a sealing gasket is provided at the contact point between the edge of the front bucket and the edge of the rear bucket.

[0021] Preferably, the inner wall of the cavity of the rear bucket is provided with a wear-resistant coating, the thickness of which is 3-5mm.

[0022] The present invention proposes a mining bucket with an openable design. Through the hinged opening and closing design of the front bucket body and the rear bucket body, combined with the active scraping action of the cleaning component, the problem of residual wet and compacted materials is solved. The opening and closing structure fully exposes the depth of the bucket, and the cleaning shovel can move vertically and quickly along the inner wall to thoroughly remove the attached materials and avoid the residue occupying the cavity.

[0023] Unloading can be achieved without tilting the entire bucket, enabling precise unloading even in confined spaces and reducing material spillage. Furthermore, the design of the claws and wear-resistant coating enhances loading capacity and equipment durability, significantly improving mining operation efficiency.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1-4 The shown is a mining bucket that can be opened and closed, including a front bucket body 1, a rear bucket body 2, a pin shaft, a telescopic cylinder 3, and a cleaning assembly.

[0032] The front bucket body 1 is located on the material inlet side of the bucket and has a through-type structure, forming the inlet part when shoveling material. Multiple sets of shovel claws 101 are installed on the front side of the part of the front bucket body 1 that contacts the ground. The shovel claws 101 are made of high-strength wear-resistant steel, and the distance between adjacent shovel claws 101 is 100-200mm to enhance the bucket's ability to insert into hard or lumpy materials.

[0033] The rear bucket body 2 is located deep within the bucket and is a bucket-shaped structure with a cavity, forming the material receiving part. The inner wall of the cavity of the rear bucket body 2 is coated with a wear-resistant coating, such as a tungsten carbide coating, with a thickness of 3-5mm, which can reduce the wear of wet materials on the inner wall and extend its service life.

[0034] The tops of the front bucket 1 and the rear bucket 2 are hinged by a pin, allowing the front bucket 1 to rotate relative to the rear bucket 2 around the pin. Rubber sealing gaskets are provided at the contact points between the edges of the front bucket 1 and the rear bucket 2, which achieve a seal when closed, preventing material from leaking out from the gaps during loading.

[0035] The telescopic cylinder 3 is connected to the side walls of the front bucket 1 and the rear bucket 2 at both ends. One end is rotatably connected to the side wall of the front bucket 1 through a trunnion, and the other end is also rotatably connected to the side wall of the rear bucket 2 through a trunnion, so as to ensure that the telescopic cylinder 3 can adapt to the angle change when the front bucket 1 is opened and closed.

[0036] The cleaning assembly includes a vertically moving shovel 204 and a drive mechanism. The shovel 204 is fitted against the inner wall of the rear bucket 2, with the gap between its edge and the inner wall controlled at 0.5-1mm to ensure effective scraping. The drive mechanism includes a lifting cylinder 201, a fixing frame 202, and a connecting rod 203. The lifting cylinder 201 is horizontally mounted on the outer back side of the rear bucket 2. The fixing frame 202 is rigidly connected to the piston rod end of the lifting cylinder 201. One end of the connecting rod 203 is welded to the bottom of the fixing frame 202, and the other end passes through the top side wall of the rear bucket 2 and is bolted to the shovel 204. When the lifting cylinder 201 extends or retracts, the fixing frame 202 drives the connecting rod 203 to move up and down, thereby driving the shovel 204 to slide vertically back and forth rapidly along the inner wall of the rear bucket 2.

[0037] A connecting frame is welded to the back of the rear bucket body 2. The connecting frame is hinged to the boom and stick of the loader through two sets of hinge shafts. The boom lifting and the stick extension and retraction are controlled by the hydraulic system of the loader to realize the lifting, lowering and working angle adjustment of the bucket.

[0038] In this embodiment, during operation:

[0039] Loading stage: The telescopic cylinder 3 is in the retracted state, and the front bucket 1 and the rear bucket 2 are tightly closed to form a complete cavity. The loader controls the bucket to descend to the ground, and the claws 101 of the front bucket 1 are inserted into the material. The material is lifted by the boom and enters the cavity of the rear bucket 2 through the front bucket 1. Wet or sticky materials are naturally compacted in the cavity.

[0040] Unloading stage: The telescopic cylinder 3 extends, pushing the front bucket 1 to rotate forward around the pivot axis, creating a discharge port with an opening of 30°-60° between the front and rear buckets 2. Simultaneously, the lifting cylinder 201 of the cleaning assembly is activated, extending the piston rod to move the fixed frame 202 upward. Through the connecting rod 203, the shovel plate 204 slides downward along the inner wall of the rear bucket 2 from the top, repeating several times to scrape off the attached residual material, which is then discharged through the discharge port. After unloading is completed, all cylinders reset, the front bucket 1 closes, and the next operating cycle begins.
