Description
Technical Field
[0001] This utility model relates to the field of buckets, specifically a loader bucket with an adjustable unloading angle. Background Technology
[0002] The loader bucket is an attachment installed on the front boom of the loader. It is the direct working device for the loader to perform core operations such as material loading, transportation, and unloading. Through the bucket support structure and linkage mechanism, it completes the excavation, lifting, and unloading of materials. It is used for loading bulk materials such as soil, sand, gravel, and coal in earthwork construction, and can also be used for light excavation of rocks and hard soil.
[0003] An investigation revealed a utility model patent (publication number: CN222862398U) disclosing a loader bucket. Its general description includes a bucket, detachably connected shovel teeth for digging bulk materials at the bucket opening, and a pushing device disposed within the bucket for facilitating the replacement of the shovel teeth. The bucket includes a bucket shell and bucket walls fixedly connected to both sides of the bucket shell. This application offers the advantages of facilitating the replacement of severely worn shovel teeth, reducing the probability of directly replacing the entire bucket, and lowering costs.
[0004] The above technical solution achieves quick replacement of shovel teeth through a detachable connection and built-in push device, reducing the probability of bucket replacement and lowering costs. However, when the bucket is unloading materials onto trucks, mixers, or other containers, a fixed bucket angle may cause materials to spill outside the container, increasing workload and reducing work efficiency.
[0005] Therefore, this utility model provides a loader bucket with an adjustable unloading angle to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects
[0016] An adjustable mechanism is installed. When the loader begins to perform the unloading action, the boom is raised and the bucket is tilted. An angle sensor monitors the actual angle of the bucket's rotation around the pivot. The control structure is fixed to the connecting lug plate via a connecting block. The connecting lug plate is fixed to the adjusting arm. The connecting rod pulls the adjusting arm, thereby controlling the angle sensor and the electro-hydraulic control valve to keep the bucket at the angle that best matches the target unloading position. This allows for quick and flexible adjustment of the optimal unloading angle, enhancing the loader's adaptability and versatility under different working conditions and improving work efficiency.
[0017] Power is transmitted through a mechanical linkage mechanism consisting of adjustable outriggers, linkage plates, and rotating shafts.

[0025] 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.
[0026] This utility model provides a loader bucket with an adjustable unloading angle, such as... Figure 1 and Figure 2 As shown, the device includes a bucket structure 1, which includes a bucket body 101 and a snap-fit plate 103. An adjustment mechanism 2 is snapped onto the outer wall of the snap-fit plate 103. The adjustment mechanism 2 includes a positioning plate 201. A rotating shaft 204 is installed inside the positioning plate 201. Linkage plates 202 are connected to both sides of the positioning plate 201. A connecting rod structure 3 is sleeved on the outside of the rotating shaft 204. The connecting rod structure 3 includes an adjusting arm 301, a connecting lug 302, and a mounting plate 303. A control structure 4 is provided inside the connecting lug 302. The control structure 4 includes an angle sensor 401. An electro-hydraulic control valve 402 is installed on the top of the angle sensor 401. A connecting block 403 is connected to the outer wall of the electro-hydraulic control valve 402. A connecting rod 404 is connected to the outer surface of the connecting block 403.
[0027] In the bucket structure 1, side plates 102 are movably installed on both sides of the bucket body 101. A snap-fit plate 103 is fixedly connected to the inner side of the side plate 102. Shovel teeth are uniformly fixed on the outside of the bucket body 101.
[0028] When in use, the device uses the snap-fit plate 103 as a key connecting part between the bucket and the adjustment mechanism 2 to transmit the force generated by the adjustment mechanism 2 and the linkage structure 3 to the bucket body 101, enabling it to flip. The side plate 102 enhances the structural strength of the bucket body 101 and prevents material from overflowing from both sides when loading materials. The shovel teeth are the parts that directly contact the ground or materials.
[0029] Furthermore, in order to improve the versatility of the device, such as Figure 3 , Figure 4 and Figure 5 As shown, the positioning plate 201 in the adjustment mechanism 2 has through holes on its outer surface. The through holes are divided into upper holes and lower holes. The positioning plate 201 has two sets of fixed clips attached to the top of the clip plate 103. The positioning plates 201 are connected by a rotating shaft 204. The two sides of the outer wall of the positioning plate 201 are movably installed with linkage plates 202. The linkage plates 202 are rotatably connected to the inside of the upper hole through the pin 203.
[0030] The adjusting arm 301 in the linkage structure 3 has two sets of adjustable arms 301 that are movably sleeved on the outer wall of the rotating shaft 204. A connecting ear plate 302 is fixedly installed on the outer surface of the adjusting arm 301. A mounting plate 303 is fixedly connected to one end of the adjusting arm 301. The connecting ear plate 302 and the linkage plate 202 are rotatably connected to the inner wall of the lower hole through the pin 203.
[0031] In the control structure 4, the angle sensor 401 is rotatably connected to the inside of the positioning plate 201. The top of the angle sensor 401 is electrically connected to the electro-hydraulic control valve 402. The electro-hydraulic control valve 402 extends upward to the inside of the connecting ear plate 302. A connecting block 403 is installed on the top of the electro-hydraulic control valve 402. The connecting block 403 is fixedly connected to the connecting ear plate 302 by bolts. A connecting rod 404 is fixedly provided at the center of the outer wall of the connecting block 403.
[0032] The electro-hydraulic control valve 402 in the control structure 4 is connected to the angle sensor 401. The angle sensor 401 detects the flipping angle of the bucket 101 in real time and feeds the signal back to the electro-hydraulic control valve 402. The electro-hydraulic control valve 402 rotates around the pin 203 by adjusting the support arm 301 and the linkage plate 202.
[0033] When in use, the rotating end of the angle sensor 401 is connected to the rotating shaft 204, and the fixed end is connected to the positioning plate 201. When the bucket 101 is tilted, the two parts inside the angle sensor 401 will rotate relative to each other. The electro-hydraulic control valve 402 is rigidly fixed to the connecting ear plate 302 through the connecting block 403 and bolts, so that the adjusting arm 301 moves together. The two sets of positioning plates 201 are fixed to the boom of the loader through the through holes on them with pins 203. The rotating shaft 204 is installed between the two sets of positioning plates 201. The linkage plate 202 is connected to the upper hole of the positioning plate 201 through the pin 203, which allows the linkage plate 202 to swing around the pin 203. When the electro-hydraulic control valve 402 pushes the adjusting arm 301 to rotate around the rotating shaft 204, the adjusting arm 301 pushes the mounting plate 303, thereby driving the bucket to tilt. The movement between the adjusting arm 301 and the linkage plate 202 is coordinated and jointly constrains the movement trajectory of the bucket.
[0034] Working principle: When it is necessary to change the unloading angle of the bucket, the hydraulic cylinder that pushes the connecting rod 404 is controlled by the electro-hydraulic control valve 402. The extension and retraction of the telescopic rod in the electro-hydraulic control valve 402 drives the adjusting arm 301 on the connecting ear plate 302 to move and rotate. This drives the adjusting arm 301 to rotate around the rotating shaft 204. Through the pin 203, the linkage plate 202 moves synchronously, realizing the rotation of the entire bucket body 101 relative to the positioning plate 201, which is usually fixed on the loading boom. This changes the bucket's tilt angle, i.e., the unloading angle, allowing for quick and flexible adjustment of the optimal unloading angle, enhancing the adaptability and versatility of the device, and improving work efficiency.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
