Description

Technical Field

[0001] This utility model relates to the field of bucket technology, and in particular to a bucket for an underground loader. Background Technology

[0002] Underground loaders are key equipment in underground engineering construction such as mines and tunnels, mainly used for loading, transporting, and unloading materials. The bucket, as its direct working component, directly affects the equipment's working efficiency and safety. The bucket is usually mounted at the front of the loader via a hinged mechanism. During operation, the equipment's propulsive force scoops materials into the bucket, which is then lifted and transported to the designated location for unloading.

[0003] However, in actual operations, especially on uneven or steep underground surfaces, loaders are prone to bumps and vibrations during material transport. This often causes some loose material, such as gravel and slag, to spill from the bucket. This spillage not only requires secondary handling and reduces operational efficiency but also pollutes the underground environment and may even pose a threat to equipment and personnel safety. Utility Model Content

[0004] This utility model provides a bucket for an underground loader, which can effectively prevent material spillage during transportation, and becomes an important technical guarantee for improving the working efficiency and safety of underground loaders.

[0005] The technical solution adopted by this utility model is as follows: a bucket for an underground shovel loader, comprising a bucket body, a fixed plate fixedly connected to one side of the bucket body, a motor fixedly installed on one side of the fixed plate, the output shaft of the motor passing through the fixed plate and fixedly connected to a first transmission wheel, a rotating shaft rotatably connected to the top of the bucket body, a second transmission wheel fixedly connected to one end of the rotating shaft, the first transmission wheel and the second transmission wheel being connected by a transmission belt, a plurality of fixed claws fixedly sleeved on the rotating shaft, side teeth on both sides of the bucket body, and a plurality of bucket teeth at the bottom of the bucket body.

[0006] As a further improvement of this utility model, the top of the bucket body is provided with a bearing seat that is connected to the loader.

[0007] As a further improvement of this utility model, both ends of the rotating shaft are rotatably connected to the bucket body through bearings.

[0008] As a further improvement of this utility model, the fixing claw has an arc-shaped structure and is used to fix the material inside the bucket body. The number of fixing claws is 4-6 and they are evenly distributed on the rotating shaft.

[0009] As a further improvement of this utility model, the bucket teeth are fixedly connected to the bottom end of the bucket body by bolts, and the bucket teeth are made of high-strength wear-resistant alloy steel with a pointed cone-shaped front end.

[0010] As a further improvement of this utility model, the bottom of the bucket body is provided with several anti-wear blocks.

[0011] The beneficial effects of this utility model are as follows: By setting a rotating shaft driven by a motor and rotated through a transmission wheel and belt at the top of the bucket body, along with multiple arc-shaped fixing claws fixed thereon, the fixing claws can rotate to the front of the bucket opening after the bucket has finished loading, forming an active barrier that effectively restrains and fixes the material inside the bucket. This fundamentally solves the problem of material spillage caused by bumps and vibrations during transportation in complex underground road conditions using traditional buckets, thereby significantly improving operating efficiency, maintaining environmental cleanliness, and enhancing safety. Simultaneously, the side teeth and replaceable high-strength bucket teeth of this utility model enhance digging capacity, while the bottom anti-wear blocks improve wear resistance. The overall structure is reasonable and reliable, highly practical, and also reduces long-term maintenance costs. Attached Figure Description

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0018] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 The bucket shown is for an underground shovel loader and includes a bucket body 1. A fixed plate 2 is fixedly connected to one side of the bucket body 1. A motor 3 is fixedly installed on one side of the fixed plate 2. The output shaft of the motor 3 passes through the fixed plate 2 and is fixedly connected to a first transmission wheel 4. A rotating shaft 5 is rotatably connected to the top of the bucket body 1. A second transmission wheel 6 is fixedly connected to one end of the rotating shaft 5. The first transmission wheel 4 and the second transmission wheel 6 are connected by a transmission belt 7. Multiple fixed claws 8 are fixedly sleeved on the rotating shaft 5. Side teeth 9 are provided on both sides of the bucket body 1. Multiple bucket teeth 10 are provided at the bottom of the bucket body 1.

[0021] like Figure 1-4 As shown, the top of the bucket body 1 in this utility model is provided with a bearing seat 11 that is connected to the loader. The bearing seat 11 is used to realize the hinge connection between the bucket body 1 and the lifting mechanism of the loader, so that the bucket body 1 can be driven by the hydraulic system of the loader to complete lifting, turning and other operations. The bearing seat 11 and the bucket body 1 are fixedly connected by welding to ensure the connection strength to withstand the load during operation.

[0022] like Figure 1-4 As shown, in this utility model, both ends of the rotating shaft 5 are rotatably connected to the bucket body 1 through bearings. The inner ring of the bearing is interference-fitted with the rotating shaft 5, and the outer ring is transition-fitted with the mounting hole preset at the top of the bucket body 1. An end cover is provided on the outside of the bearing to prevent impurities such as underground dust from entering the bearing and affecting its rotational accuracy and service life.

[0023] like Figure 1-4As shown, in this invention, the fixing claw 8 has an arc-shaped structure, the curvature of which matches the curvature of the opening of the bucket body 1. When the fixing claw 8 rotates to the front of the opening of the bucket body 1 under the drive of the rotating shaft 5, the arc-shaped fixing claw 8 can better fit the surface of the material, thereby more effectively fixing the material inside the bucket body 1 and preventing it from moving out of the bucket opening due to bumps during transportation. The number of fixing claws 8 is preferably 5, and they are evenly distributed along the axial direction of the rotating shaft 5. This arrangement can make the material be subject to a more uniform constraint force in the width direction, avoiding local spillage due to insufficient fixing. The fixing claw 8 is made of high-strength manganese steel, which has good toughness and wear resistance, and its surface can also be quenched to improve hardness.

[0024] like Figure 1-4 As shown, in this utility model, the bucket teeth 10 are fixedly connected to the bottom end of the bucket body 1 by bolts. Multiple bolt holes are provided at the bottom end of the bucket body 1 corresponding to the positions of the bucket teeth 10. The tail of the bucket teeth 10 is fastened to the bucket body 1 by high-strength bolts. This detachable connection method facilitates individual replacement of the bucket teeth 10 after wear, reducing maintenance costs. The bucket teeth 10 are made of ZGMn13 high-strength wear-resistant alloy steel, which has excellent impact and wear resistance. The front end of the bucket teeth 10 is conical with a cone angle of 30°-45° to reduce resistance when inserting material during loading and improve loading efficiency. The number of bucket teeth 10 is determined according to the width of the bucket body 1, typically 5-7, and they are evenly arranged along the transverse direction of the bucket body 1.

[0025] like Figure 2 As shown, the bottom of the bucket body 1 of this utility model is provided with a number of anti-wear blocks 12. The anti-wear blocks 12 are spaced apart at the bottom of the bucket body 1. The anti-wear blocks 12 are welded to the bucket body 1. Their material is the same as that of the bucket teeth 10, which is ZGMn13 wear-resistant alloy steel. The anti-wear blocks 12 can effectively protect the bottom of the bucket body 1, prevent the bucket body 1 from directly contacting the ground or hard materials and causing wear, and extend the overall service life of the bucket body 1.

[0026] Working Principle: In practical implementation, when the loader needs to perform loading operations, the bucket body is first connected and fixed to the loader's lifting mechanism via the bearing seat. Before the operation begins, the motor is in its initial state. At this time, the fixed claws are in a non-working position at the top of the bucket body under the drive of the rotating shaft, and will not obstruct the material loading. The loader drives the bucket body to descend, using the bottom conical teeth to insert into the material pile. At the same time, the side teeth on both sides can assist in crushing and laterally gathering the material, improving loading efficiency. After loading is completed, the loader lifts the bucket body through the lifting mechanism. At this time, the operator can start the motor. The motor's output shaft drives the first transmission wheel to rotate, and the first transmission wheel drives the second transmission wheel to rotate through the transmission belt, thereby causing the rotating shaft to rotate accordingly. The fixed claws on the rotating shaft rotate with the shaft, gradually flipping down from the top of the bucket body to the front of the bucket body opening. Since the fixed claws are arc-shaped structures adapted to the curvature of the bucket opening, and there are 5 evenly distributed claws, they can closely fit the material surface, effectively intercepting and fixing the material inside the bucket body. During transportation, even when encountering uneven surfaces or slopes underground causing bumps and vibrations, the fixed claws firmly restrain the material, preventing it from spilling out of the bucket. Upon reaching the designated unloading point, the operator reverses the motor, causing the rotating shaft and fixed claws to rotate upwards to their initial position, releasing the material. The loader then controls the bucket body to tilt, smoothly unloading the material. Furthermore, the anti-wear blocks at the bottom of the bucket body rub against the ground during loading and transportation, protecting the bottom of the bucket body from excessive wear and extending its service life. The bucket teeth are bolted together, allowing for easy individual disassembly and replacement when wear occurs, reducing maintenance costs. Throughout the process, the bearings ensure smooth rotation of the rotating shaft, and the end covers effectively prevent dust from entering, ensuring stable operation of the transmission system.
