Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically, to an adjustable capacity loader bucket. Background Technology

[0002] As the core working device of construction machinery, the loader bucket is a rigid load-bearing container specifically designed for efficient loading and short-distance transfer of loose materials. In actual operation, the bucket is driven by a hydraulic system to complete a series of continuous actions such as inserting into the material pile, loading materials, lifting and transporting, and unloading materials. Its structural strength, geometry, and wear resistance directly affect the working efficiency and service life of the loader.

[0003] Traditional loader buckets mostly have a fixed capacity. In confined spaces, the bucket's excessive width can restrict operation, while in open areas, insufficient capacity necessitates frequent loading and unloading, resulting in low efficiency. Furthermore, while some existing buckets offer hydraulic cylinder-based width adjustment, they lack a reliable self-locking mechanism, leading to displacement deviations after prolonged use. Therefore, we propose an adjustable-capacity loader bucket to address these issues. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background section, most traditional buckets have a fixed capacity. When operating in narrow spaces, the bucket's excessive width can restrict operation, while in open spaces, insufficient capacity necessitates frequent loading and unloading, resulting in low efficiency. Furthermore, although some existing buckets have a solution for adjusting the bucket width using hydraulic cylinders, they lack a reliable self-locking mechanism, which can easily lead to displacement deviations after long-term use.

[0021] To solve this technical problem, this utility model provides an adjustable capacity loader bucket, which is used in working scenarios where the capacity of the loading bucket needs to be adjusted.

[0022] For details, please refer to Figures 1-5 Adjustable capacity loader buckets specifically include: A first bucket 1 and two second buckets 2 are symmetrically arranged on both sides of the first bucket 1. An adjustment component 3 for adjusting the distance between the two second buckets 2 is installed on the upper end of the first bucket 1. A fixing component 4 for limiting the position of the two second buckets 2 is installed on the upper end of the first bucket 1.

[0023] The adjustable capacity loader bucket provided by this utility model allows for the adjustment of the distance between the two second bucket bodies 2 through the adjustment component 3, enabling the bucket to adapt to narrow or wide construction environments. Furthermore, the self-locking characteristic of the adjustment component 3 ensures that the position remains stable after adjustment, preventing accidental displacement of the second bucket bodies 2 due to vibration or external force, thus ensuring the reliability and safety of the loading capacity adjustment. Subsequently, the fixing component 4 further limits the position of the second bucket bodies 2, effectively preventing the second bucket bodies 2 from loosening or shifting during operation, further enhancing the overall structural stability.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1, please refer to Figures 1-4 An adjustable-capacity loader bucket includes a first bucket body 1 and two second bucket bodies 2, which are symmetrically arranged on both sides of the first bucket body 1. An adjusting assembly 3 for adjusting the distance between the two second bucket bodies 2 is installed on the upper end of the first bucket body 1. A fixing assembly 4 for limiting the movement of the two second bucket bodies 2 is also installed on the upper end of the first bucket body 1. When the distance between the two second bucket bodies 2 needs to be adjusted, a motor 303 drives a worm gear 306 to rotate. The worm gear 306 meshes with a worm wheel 305, causing a rotating rod 304 to rotate. A spur gear 307 at the lower end of the rotating rod 304 engages with two racks 3... 09 meshes, rack 309 is fixed on support frame 308, and support frame 308 is connected to the second bucket body 2. When motor 303 starts, spur gear 307 simultaneously pushes racks 309 on both sides to move in opposite directions, so that the two second bucket bodies 2 move towards the center or expand outward in sync, thereby adjusting the bucket width. In narrow spaces, it shrinks to the conventional size, and in open spaces, it expands to increase capacity, so that the bucket can adapt to narrow or wide construction environments. The entire adjustment process is automatically locked after adjustment by the self-locking characteristics of worm 306 and worm wheel 305 to prevent accidental displacement caused by vibration or external force.

[0028] Furthermore, such as Figures 2-3 As shown, the adjustment component 3 includes guide grooves 301, and there are two sets of guide grooves 301. The guide grooves 301 are arranged in pairs, and the two sets of guide grooves 301 are respectively opened on the side walls of the two second buckets 2. The inner wall of the first bucket 1 is fixedly connected to two sets of symmetrically arranged guide blocks 302. The guide blocks 302 are arranged in pairs, and the two sets of guide blocks 302 are slidably connected in the two sets of guide grooves 301. When the second bucket 2 moves, the guide blocks 302 slide in the guide grooves 301 to form a double-track guide, ensuring that the second bucket 2 moves smoothly along a straight line and avoiding deviation or jamming.

[0029] Furthermore, such as Figure 4 As shown, a motor 303 is fixedly installed on the upper end of the first bucket body 1. A rotating rod 304 is rotatably sleeved at the middle of the upper end of the first bucket body 1. A worm gear 305 is fixedly connected to the upper end of the rotating rod 304. A worm 306 is fixedly connected to the output end of the motor 303. The worm 306 and the worm gear 305 mesh with each other. The motor 303 drives the worm 306 to rotate, thereby driving the worm gear 305 to move, thus realizing the adjustment of the bucket capacity. Utilizing the self-locking characteristics of the worm gear 305 and worm 306, the position can be automatically locked after the adjustment is completed, effectively preventing the risk of displacement caused by vibration or external force. At the same time, it provides stable and high-load transmission performance, significantly enhancing the reliability and safety of bucket operation.

[0030] Furthermore, such as Figure 4 As shown, a spur gear 307 is fixedly connected to the lower end of the rotating rod 304, and a support frame 308 is fixedly connected to the upper end of each of the two second buckets 2. The two support frames 308 are arranged in a centrally symmetrical manner. A rack 309 is fixedly connected to one side wall of each support frame 308 near the spur gear 307. The two racks 309 are arranged in a centrally symmetrical manner and are located on both sides of the spur gear 307. Both racks 309 mesh with the spur gear 307. Through the meshing transmission of the spur gear 307 and the two symmetrical racks 309, the synchronous reverse movement of the two second buckets 2 is realized. The centrally symmetrical double rack 309 drive structure ensures the accuracy and synchronicity of the adjustment of the distance between the second buckets 2. At the same time, the meshing transmission of the spur gear 307 and the rack 309 has the characteristics of high rigidity and low backlash, which can withstand the impact load during loading operations.

[0031] Example 2 further optimizes the adjustable capacity loader bucket provided in Example 1, specifically, as follows: Figure 1 , Figure 2 and Figure 5 As shown, the fixing component 4 includes a slot 401 and an electric push rod 402. There are two sets of slots 401, which are symmetrically arranged. The two sets of slots 401 are respectively opened on one side of the upper end of the two second buckets 2. There are two electric push rods 402, which are symmetrically arranged. The two electric push rods 402 are fixedly connected to the upper end face of the first bucket 1. The output ends of the two electric push rods 402 penetrate the first bucket 1, and the output ends of the two electric push rods 402 are fixedly connected to a locking block 403. The two locking blocks 403 respectively cooperate with the two sets of slots 401. When the adjustment component 3 completes the spacing adjustment, the electric push rod 402 pushes the locking block 403 at the output end to move downward. The locking block 403 is locked into the slot 401 of the second bucket 2. This locking structure provides rigid limit to prevent the second bucket 2 from loosening or shifting due to material impact during loading operations, which significantly improves the structural stability.

[0032] Furthermore, such as Figure 5 As shown, an infrared transmitter 404 is fixedly installed on the lower end face of both locking blocks 403, and an infrared receiver 405 is fixedly installed on the bottom of the inner wall of each slot 401. Through the coordinated work of the infrared transmitter 404 and the infrared receiver 405, the docking status of the locking block 403 and the slot 401 can be monitored in real time. The non-contact infrared sensing technology can accurately detect whether the locking position is in place, avoiding the problems of easy wear or poor contact of traditional mechanical limit switches. At the same time, the reliability of the fixing component 4 is ensured through photoelectric signal feedback, which significantly improves the safety and automation level after the bucket is adjusted.

[0033] It is worth noting that both the infrared transmitter 404 and the infrared receiver 405 are existing technologies. The infrared transmitter 404 is mainly composed of an infrared light-emitting diode, which generates an infrared light signal of a specific wavelength by exciting the semiconductor material with current. The infrared receiver 405 includes an infrared photodiode and integrated amplification, filtering and demodulation circuits, which are responsible for receiving the infrared beam and converting it into an electrical signal output. The two work together to accurately detect whether the locking position is in place, which will not be elaborated here.

[0034] Example 3 further optimizes the adjustable capacity loader bucket provided in Example 1, specifically, as follows: Figures 1-4 As shown, two guide components are installed on the upper part of the outer wall of the first bucket 1. The two guide components are symmetrically arranged. The guide components include a guide ring 5, which is fixedly connected to one side of the outer wall of the first bucket 1. A guide post 6 is fixedly connected to one side of the outer wall of the second bucket 2. The guide post 6 is slidably connected to the inner wall of the guide ring 5. The sliding cooperation between the guide ring 5 and the guide post 6 realizes the linear guiding movement of the second bucket 2 relative to the first bucket 1, ensuring that the movement trajectory during the extension and retraction of the bucket is accurate and stable, and effectively preventing off-center loading or jamming.

[0035] Furthermore, such as Figure 3 and Figure 4 As shown, a protective cover 7 is fixedly connected to the middle of the upper end of the first bucket body 1. The end of the worm gear 306 away from the motor 303 is fixedly connected to the inner wall of the protective cover 7. The output end of the motor 303 passes through the protective cover 7. The protective cover 7 protects the connection between the worm gear 306 and the motor 303, effectively isolating external gravel and foreign objects from entering the transmission, preventing abnormal wear or jamming of the worm wheel 305 and worm gear 306 transmission pair due to contamination. At the same time, the rigid fixing method of the protective cover 7 not only ensures the coaxiality accuracy of the output shaft of the motor 303, but also significantly improves the sealing performance and operational stability of the bucket adjustment assembly 3 under harsh working conditions.

[0036] Furthermore, such as Figure 2 As shown, the outer wall of the first bucket body 1 is fixedly connected with three connecting seats 8. The three connecting seats 8 adopt a three-point support structure design, forming a stable triangular force distribution, which effectively enhances the connection strength between the bucket and other components. At the same time, the layout of multiple connection points can not only disperse concentrated loads, but also provide the flexibility of multi-directional installation interfaces, ensuring that the bucket maintains structural stability when subjected to impact loads under complex working conditions, and significantly improving the reliability and service life of the overall equipment.

[0037] The adjustable capacity loader bucket provided by this utility model is used as follows: When it is necessary to adjust the distance between the two second buckets 2, the motor 303 drives the worm 306 to rotate. The worm 306 meshes with the worm wheel 305, which drives the rotating rod 304 to rotate. The spur gear 307 at the lower end of the rotating rod 304 meshes with the two racks 309. The racks 309 are fixed on the support frame 308, and the support frame 308 is connected to the second bucket 2. When the motor 303 starts, the spur gear 307 simultaneously pushes the racks 309 on both sides to move in opposite directions, so that the two second buckets 2 move towards the center or expand outward in sync, thereby adjusting the width of the bucket. In narrow spaces, it shrinks to the conventional size, and in open spaces, it expands to increase the capacity, so that the bucket can adapt to narrow or wide construction environments. The entire adjustment process is automatically locked after the adjustment is completed by the self-locking characteristics of the worm 306 and the worm wheel 305 to prevent accidental displacement caused by vibration or external force. After the adjustment component 3 completes the spacing adjustment, the electric push rod 402 pushes the output end of the locking block 403 downward. The locking block 403 is locked into the slot 401 of the second bucket 2. This locking structure provides rigid limit to prevent the second bucket 2 from loosening or shifting due to material impact during loading operations, and significantly improves the structural stability.
