Description

Technical Field

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

[0002] With the acceleration of industrialization and the increasing demand for efficient material handling equipment in industries such as construction, mining, and ports, loaders, as a type of engineering machinery widely used in material handling, short-distance transportation, and light digging operations, are becoming increasingly important. Traditional manual handling methods can no longer meet the requirements of large-scale production and rapid logistics, while loaders, with their powerful engines, flexible operation, and efficient working capabilities, have become an indispensable piece of equipment in modern industrial production.

[0003] Currently, when most loaders are in use, the bucket body tends to stick to the inside of the bucket when loading materials with high moisture content and stickiness (such as soil). This adhesion reduces the capacity of each load, requiring more frequent loading and unloading operations, thus reducing overall work efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to address the shortcomings of existing technologies by proposing a loader bucket. When in use, the device drives the threaded rod to rotate via a first servo motor, which in turn moves the scraper inside the bucket body to automatically clean the soil inside the bucket body. This effectively prevents the reduction in loading capacity due to soil accumulation, significantly improving work efficiency. At the same time, it effectively avoids problems such as equipment overload and accelerated wear caused by soil accumulation, helping to maintain the long-term stable operation and good performance of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loader bucket, comprising a bucket body connected to the front end of a loader via a bucket arm, a connecting shell fixedly connected to the upper end of the bucket body, a first servo motor disposed on one side of the connecting shell, the output end of the first servo motor extending into the connecting shell and fixedly connected to a threaded rod, a slider threadedly sleeved on the outer side of the threaded rod, a scraper fixedly connected to the lower end of the slider, the scraper being located inside the bucket body; a second servo motor disposed on the front side wall of the bucket body, a drive gear sleeved on the outer side of the output end of the second servo motor, a driven gear meshing on one side of the drive gear, a connecting shaft passing through the center of the driven gear, and bucket teeth fixedly connected at even intervals to the outer side of the connecting shaft.

[0006] Through the above technical solution, when in use, the device uses a first servo motor to drive the threaded rod to rotate, which in turn moves the scraper inside the bucket body, automatically cleaning the soil inside the bucket body. This effectively avoids the reduction in loading capacity due to soil accumulation, significantly improving work efficiency. Simultaneously, it effectively avoids problems such as equipment overload and accelerated wear caused by soil accumulation, helping to maintain the long-term stable operation and good performance of the equipment. A second servo motor drives the connecting shaft to rotate, enabling the drive system to effectively transmit power, ensuring flexible adjustment of the bucket teeth, thereby improving working accuracy, reducing energy loss, and increasing overall machine efficiency.

[0007] Furthermore: the bottom of the connecting shell is open, and the lower end of the slider extends through the open to fix and connect the scraper; the outline shape of the scraper matches the inner cavity shape of the bucket body.

[0008] The above technical solution enables the scraper to remove residue from the inner wall of the bucket more thoroughly.

[0009] Furthermore, the end of the threaded rod furthest from the first servo motor is rotatably connected to the connecting shell.

[0010] By using the above technical solution, precise rotation control can be achieved by rotatably connecting the threaded rod to the connecting shell, ensuring the stable operation of the threaded rod under the drive of the servo motor, and increasing the flexibility and efficiency of operation.

[0011] Furthermore: a guide rod is fixedly connected across the bucket body inside the bucket body, and a guide groove is provided at the lower end of the scraper. The guide rod and the guide groove are slidably connected.

[0012] By using the above technical solution, a guide rod is installed inside the bucket body and slidably connected to the guide groove of the scraper. This can effectively ensure the smooth movement of the scraper during operation, prevent wear caused by unstable movement or deviation, improve the stability and durability of the bucket body and scraper system, and ensure working accuracy.

[0013] Furthermore: both ends of the slider are fixedly connected with corrugated plates, both ends of the bucket body are fixedly connected with storage boxes, and the other ends of the two corrugated plates are fixedly connected to the inner wall of the storage box on the nearest side.

[0014] The above technical solution uses a corrugated plate as a barrier to effectively prevent foreign objects such as mud and stones from entering the connecting shell and protect the threaded rod, while the storage box facilitates the storage of the corrugated plate when it is not in use.

[0015] Furthermore: the front end of the bucket body is fixedly connected with auxiliary teeth at even intervals, and multiple auxiliary teeth are alternately arranged with multiple bucket teeth, and the connecting shaft rotates through multiple auxiliary teeth at the same time.

[0016] By using the above technical solution, auxiliary teeth are set on the end face of the bucket body and arranged alternately with the bucket teeth, the grabbing ability and efficiency of the bucket can be improved, ensuring that the bucket can better adapt to materials of different materials during operation.

[0017] Furthermore, the end of the connecting shaft away from the second servo motor is rotatably connected to the bucket body.

[0018] By using the above technical solution, precise rotation control can be achieved by rotating the connecting shaft to the bucket body, ensuring stable operation of the connecting shaft under the drive of the servo motor, and increasing operational flexibility and efficiency.

[0019] Furthermore, a protective shell is fixedly connected to one side of the bucket body, and the protective shell covers the outside of the second servo motor, the drive gear, and the driven gear.

[0020] Through the above technical solutions, the protective shell can effectively protect the gear system from interference and damage from the external environment, prevent foreign objects from entering the gear system, reduce wear and failure, extend the service life of gear components, and improve the overall safety and reliability of the equipment.

[0021] This utility model has the following beneficial effects:

[0022] 1. The loader bucket proposed in this utility model, when in use, is driven by a first servo motor to rotate the threaded rod, which drives the scraper to move inside the bucket body, automatically cleaning the soil inside the bucket body. This effectively avoids the reduction in loading capacity caused by soil accumulation, significantly improving work efficiency. At the same time, it effectively avoids problems such as equipment overload and accelerated wear caused by soil accumulation, and helps to maintain the long-term stable operation and good performance of the equipment.

[0023] 2. The loader bucket proposed in this utility model, when in use, is driven by a second servo motor to rotate the connecting shaft, so that the angle of the bucket teeth at the front end of the bucket body can be adjusted, which enhances the adaptability of the loader to different materials and working environments. At the same time, it effectively reduces the resistance during digging and the direct contact area between the bucket teeth and the ground, improves the digging efficiency of the loader, reduces the wear of the bucket body and bucket teeth, and extends the service life of the equipment.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings of the specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of this utility model, and not all of them. Based on the specific embodiments of this utility model, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Reference Figures 1-4 This utility model provides a loader bucket, which is installed at the front end of the loader via a bucket arm 1. The bucket arm 1 is a conventional technology and is only shown in the figure for illustrative purposes and will not be described in detail. The loader bucket includes a bucket body 2, with one end of the bucket arm 1 connected to a drive mechanism and the other end connected to the bucket body 2, driving the bucket body 2 to lift and tilt.

[0032] The bucket includes a bucket body 2, with a connecting shell 3 fixedly connected to the top of the bucket body 2. A first servo motor 4 is mounted on one end face of the connecting shell 3. The output end of the first servo motor 4 extends into the interior of the connecting shell 3 and is fixedly connected to a threaded rod 5. The length of the threaded rod 5 is almost equal to the width of the bucket body 2. A slider 6 is threaded onto the outer side of the threaded rod 5. The bottom of the connecting shell 3 is open, and a scraper 7 is fixedly connected to the lower end of the slider 6 through the open. The outline of the scraper 7 matches the inner cavity shape of the bucket body 2, and it slides along the inner wall of the bucket body 2 to scrape under the drive of the slider 6. The end of the threaded rod 5 away from the first servo motor 4 is rotatably connected to the connecting shell 3. By rotatably connecting the threaded rod 5 to the connecting shell 3, precise rotation control can be achieved, ensuring stable movement of the threaded rod 5 under the drive of the servo motor, thereby improving the accuracy and response speed of the equipment and increasing the flexibility and efficiency of operation.

[0033] In operation, the device uses a first servo motor 4 to drive the threaded rod 5 to rotate, causing the slider 6 to slide on the threaded rod 5. The scraper 7, driven by the slider 6, slides along the inner wall of the bucket body 2 to scrape the soil. This automatically cleans the soil inside the bucket body 2, effectively preventing soil adhesion and reducing the loading capacity for subsequent loads, significantly improving work efficiency. Simultaneously, it effectively avoids equipment overload and accelerated wear caused by soil accumulation, helping to maintain long-term stable operation and good performance of the equipment.

[0034] Furthermore, a guide rod 10 is fixedly connected across the lower end of the bucket body 2, and a guide groove 18 is provided at the lower end of the scraper 7. The guide rod 10 and the guide groove 18 are slidably connected. By setting the guide rod 10 inside the bucket body 2 and slidably connecting it with the guide groove 18 of the scraper 7, the smooth movement of the scraper 7 during operation can be effectively ensured, preventing wear caused by unstable movement or deviation, improving the stability and durability of the bucket body 2 and scraper 7 system, and ensuring working accuracy.

[0035] Furthermore, corrugated plates 8 are fixedly connected to both ends of the slider 6, and storage boxes 9 are fixed to the upper ends of both ends of the bucket body 2. One end of the corrugated plate 8 is connected to the slider 6, and the other end is connected to the inner wall of one side of the storage box 9. The corrugated plate 8 acts as a barrier, blocking the bottom opening of the connecting shell 3, which can effectively prevent foreign objects such as mud and stones from entering the interior of the connecting shell 3, interfering with the normal operation of the threaded rod 5, causing the threaded rod 5 to be damaged or jammed. The storage box 9 facilitates the storage of the corrugated plate 8 when it is not in use.

[0036] On the other hand, a second servo motor 13 is installed on the front side wall of the bucket body 2. A drive gear 14 is sleeved on the output end of the second servo motor 13. A driven gear 15 is meshed with one side of the drive gear 14. A connecting shaft 16 is fixedly inserted through the center of the driven gear 15. Bucket teeth 17 are evenly spaced and fixedly connected to the outside of the connecting shaft 16. Simultaneously, auxiliary teeth 12 are evenly spaced and fixedly connected to the front end of the bucket body 2. Multiple auxiliary teeth 12 and multiple bucket teeth 17 are alternately arranged. The connecting shaft 16 also passes through multiple auxiliary teeth 12, and the two are rotatably connected. By setting auxiliary teeth 12 and bucket teeth 17 at the end of the bucket body 2 and arranging them alternately, the bucket teeth 17 can rotate under the drive of the connecting shaft 16. Therefore, the gripping ability and efficiency of the bucket body 2 can be improved, ensuring that the bucket body 2 can better adapt to materials of different materials during operation. The end of the connecting shaft 16 away from the second servo motor 13 is rotatably connected to the bucket body 2. The rotatable connection between the connecting shaft 16 and the bucket body 2 enables the drive system to effectively transmit power, ensuring the precise operation and flexible adjustment of the bucket teeth 17, thereby improving working accuracy, reducing energy loss, and improving the overall efficiency of the machine.

[0037] Furthermore, a protective shell 11 is fixed on the side wall of the bucket body 2 to cover the motor and gears. The protective shell 11 can effectively protect the gear system from interference and damage from the external environment, prevent foreign objects from entering the drive system, reduce wear and failure, extend the service life of components, and improve the overall safety and reliability of the equipment.

[0038] The working principle of the loader bucket is as follows: During use, the first servo motor 4 drives the threaded rod 5 to rotate, allowing the scraper 7 to move along a specific trajectory of the guide rod 10 inside the bucket body 2. After the loader completes a digging or loading operation, the first servo motor 4 automatically starts, and the scraper 7 removes the soil from the inner wall of the bucket body 2. This automated process not only prevents soil accumulation inside the bucket body 2 but also ensures that each loading reaches the maximum capacity, avoiding a decrease in loading efficiency due to soil residue. In addition, the second servo motor 13 controls the angle adjustment of the bucket teeth 17 inside the bucket body 2. By precisely adjusting the angle of the bucket teeth 17, the loader can better adapt to different material characteristics and working environments. For example, when digging wet clay, the bucket teeth 17 can be adjusted to a more suitable angle for penetration, while when handling loose materials, it can be adjusted to an angle that reduces resistance. This flexibility not only improves digging efficiency but also reduces the direct contact area between the bucket teeth 17 and the ground, thereby reducing the wear rate and extending the service life of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, they can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
