Description

Technical Field

[0001] This utility model belongs to the field of bucket technology, specifically an adjustable angle bucket device. Background Technology

[0002] Buckets are core components widely used in engineering operations. They are typically mounted on excavators, loaders, and other engineering machinery and are mainly used for digging, loading, transporting, and leveling soil, sand, gravel, and other materials. Their structural and functional design directly affects the equipment's operational adaptability and overall efficiency.

[0003] In existing technologies, the angle of traditional buckets is mostly fixed, making it difficult to flexibly adjust the tilt state according to the needs of actual operation scenarios. In actual construction, when facing different working conditions such as slope trimming, lateral unloading of materials, and operation in narrow spaces, fixed-angle buckets often require operators to frequently adjust the position of the equipment body to complete the operation. This not only makes the operation process cumbersome but also easily leads to insufficient operation accuracy and increases labor intensity. At the same time, fixed-angle buckets are less adaptable to complex working environments, failing to fully utilize the operational potential of engineering equipment, limiting the improvement of overall operation efficiency, and making it difficult to meet diverse construction needs. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an adjustable angle bucket device, which has the advantages of convenient and stable adjustment of the bucket's operating angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable angle bucket device, including a mounting frame, a reinforcing frame connected to the surface of the mounting frame, a transmission arm connected to the surface of the reinforcing frame, a protective box rotatably connected to the surface of the transmission arm, a protective component and an angle adjustment component respectively provided on the protective box, a fixed seat connected to the inner side of the protective box, a drive source connected to the surface of the fixed seat, and two adapter seats connected to the surface of the protective box; The surface of the protective component is electrically connected to the power output end of the drive source to provide a protective force for the angle adjustment component; The surface of the angle adjustment component is poweredly connected to the power output end of the protective component to provide an angle adjustment force to the angle adjustment component.

[0006] Preferably, the protective component includes a torque reducer, which is disposed on the power output end of the drive source, and the output end of the torque reducer is connected to a torque limiter.

[0007] Preferably, the angle adjustment assembly includes a transmission worm gear, a support rod, and a reinforcing rod. The transmission worm gear is disposed on the output end of the torque limiter. The support rod is rotatably disposed on the inner side of the bottom end of the protective box. A transmission worm wheel is connected to the top end of the support rod. A transmission rod is connected to the top end of the transmission worm wheel. One end of the transmission rod is connected to the bucket body. The reinforcing rod is rotatably disposed on the inner wall of the front of the protective box.

[0008] Preferably, the transmission worm gear is meshed with the transmission worm.

[0009] Preferably, one end of the reinforcing rod is connected to one end of the transmission worm gear.

[0010] Preferably, a sealing ring is attached to the surface of the transmission rod, and the sealing ring is made of nitrile rubber.

[0011] Preferably, the surfaces of both adapter seats are rotatably connected to the surface of the mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a torque reducer to easily amplify the output torque of the drive source. Only a small power source is needed to drive the bucket body to complete the angle adjustment under heavy load conditions, avoiding the cost and space occupation of a high-power power source. At the same time, the torque limiter can automatically slip to cut off the power transmission when the bucket body encounters overload scenarios such as jamming, which helps to protect the transmission worm and transmission worm wheel, improve their service life and the stability of construction operations.

[0013] 2. This utility model uses a simple and quick transmission mechanism that drives the worm gear to rotate the bucket body for angle adjustment. It is suitable for operation scenarios with high requirements for angle accuracy, such as slope trimming and unloading in narrow spaces. Furthermore, the self-locking characteristics of the transmission worm gear and worm wheel, combined with the overload protection of the torque limiter, not only keep the bucket body angle stable and locked, but also help avoid the risk of damage caused by overload, making it suitable for complex and harsh engineering operation environments.

Detailed Implementation

[0016] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides an adjustable angle bucket device, including a mounting frame 1, a reinforcing frame 4 connected to the surface of the mounting frame 1, a transmission arm 5 connected to the surface of the reinforcing frame 4, and a protective box 6 rotatably connected to the surface of the transmission arm 5 to provide protection for the drive source 8. The protective box 6 is respectively provided with a protective component 2 and an angle adjustment component 3. A fixed seat 7 is connected to the inner side of the protective box 6, and the drive source 8 is connected to the surface of the fixed seat 7. Two adapter seats 9 are connected to the surface of the protective box 6. The double adapter seats 9 facilitate the equalization of the force on the protective box 6 and improve the stability of the connection between the protective box 6 and the mounting frame 1. The surface of the protective component 2 is poweredly connected to the power output end of the drive source 8 to provide a protective force for the angle adjustment component 3; The surface of the angle adjustment component 3 is poweredly connected to the power output end of the protective component 2 to provide the angle adjustment force to the angle adjustment component 3.

[0018] Specifically, the protective component 2 includes a torque reducer 21, which is connected to the drive source 8 to amplify the output torque of the drive source 8, so that the small drive source 8 can drive the angle adjustment action under heavy load conditions. The torque reducer 21 is set on the power output end of the drive source 8, and the output end of the torque reducer 21 is connected to a torque limiter 22. The torque limiter 22 is connected in series with the torque reducer 21 to automatically cut off the power when the angle adjustment is overloaded, so as to avoid damage to the torque reducer 21, the transmission worm 31 and the transmission worm wheel 33, etc.

[0019] Furthermore, the angle adjustment assembly 3 includes a transmission worm gear 31, a support rod 32, and a reinforcing rod 36. The transmission worm gear 31 is located on the output end of the torque limiter 22. The support rod 32 is rotatably located on the inner side of the bottom end of the protective box 6. The top end of the support rod 32 is connected to a transmission worm wheel 33, which converts the rotation of the transmission worm wheel 33 into an angle adjustment force for the bucket body 35. The top end of the transmission worm wheel 33 is connected to a transmission rod 34, one end of which is connected to the bucket body 35. The reinforcing rod 36 is rotatably located on the inner wall of the front of the protective box 6.

[0020] Furthermore, the transmission worm gear 33 is meshed with the transmission worm 31. Through the self-locking characteristics of the transmission worm gear 33 and the transmission worm 31, the stability of the angle of the bucket body 35 after adjustment is improved.

[0021] It is worth noting that one end of the reinforcing rod 36 is connected to one end of the transmission worm 31, which facilitates stable support for the transmission worm 31 and prevents the transmission worm 31 from bending and deforming due to force.

[0022] It is worth noting that a sealing ring is connected to the surface of the transmission rod 34. The sealing ring is made of nitrile rubber, which has excellent oil resistance and wear resistance, making it more suitable for the harsh environment of engineering operations and extending the service life of the sealing ring and the transmission rod 34.

[0023] It is worth mentioning that the surfaces of both adapters 9 are rotatably connected to the surface of the mounting bracket 1, which facilitates the equalization of the rotational force on the protective box 6.

[0024] The torque reducer 21, torque limiter 22, transmission worm 31, and transmission worm wheel 33 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: First, the drive arm 5 drives the protective box 6 and the bucket body 35 to tilt along the horizontal axis. Then, when it is necessary to drive the bucket body 35 to tilt along the vertical axis, the drive source 8 is controlled to operate. The driving force of the drive source 8 is amplified by the torque reducer 21 and then transmitted to the transmission worm 31 through the torque limiter 22. At this time, the rotation of the transmission worm 31 drives the meshing transmission worm wheel 33 to rotate. The transmission worm wheel 33 then drives the bucket body 35 to complete the left and right angle deflection adjustment through the transmission rod 34. The operation is simple, and the drive source 8 can be turned off after the bucket body 35 is adjusted to the target angle. The self-locking characteristics of the transmission worm 31 and the transmission worm wheel 33 can keep the bucket body 35 stably maintaining the adjusted angle and avoid deviation.
