Description

Technical Field

[0001] This invention relates to the field of loader technology, and more particularly to a quick-change bucket loader. Background Technology

[0002] A loader is a widely used earthmoving machine in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is primarily used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. With different auxiliary attachments, it can also be used for bulldozing, lifting, and loading and unloading other materials such as timber. In road construction, especially on high-grade highways, loaders are used for filling and excavating roadbeds, and for collecting and loading asphalt mixtures and cement concrete materials. They can also be used for pushing and transporting soil, leveling ground, and towing other machinery. Due to its advantages such as high operating speed, high efficiency, good maneuverability, and easy operation, the loader has become one of the main types of machinery used in earthmoving construction projects.

[0003] Loaders primarily use buckets for loading operations. A bucket consists of components such as a tooth base plate, bottom plate, side plates, wall plates, lug plates, back plate, bucket lug plates, bucket lug sleeves, bucket teeth, tooth base, guard plates, or bucket corners.

[0004] Currently, during the loading operation of loaders, the teeth in the bucket are the most severely damaged or worn parts. However, replacing the existing teeth is quite troublesome, mostly requiring external hammering of the pins to make the teeth removable and install, which brings trouble to the operation and reduces the efficiency of the operation. Secondly, when the loader is transporting, the lack of a shielding structure on the bucket causes dust pollution when the bucket is being unloaded, thus affecting the working environment. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-change bucket loader. This loader utilizes a cover plate to prevent dust from being generated during transport and can also perform dust suppression during unloading, further reducing dust dispersion. Furthermore, it allows for quick disassembly and assembly of the tooth tips to facilitate replacement when the tips wear out.

With the cooperation of the second worm wheel and the worm, the baffle can be pulled to open the atomizing nozzle for dust suppression.

[0024] 4. By unscrewing the sealing cover, the locking block can be disengaged from the slot, thus releasing the restriction of the plug rod and allowing the plug plate to be pulled out of the plug slot, achieving the purpose of tooth tip disassembly. Conversely, installation can be performed. Attached Figure Description

[0041] Working principle:

[0042] During loading, the drive motor 12 is first turned on. The output shaft of the drive motor 12 rotates, which drives the rotating rod 10 to rotate. The rotating rod 10 rotates, which drives the worm gear 21 to rotate. The worm gear 21 rotates, which drives the first worm wheel 8 to rotate. The first worm wheel 8 rotates, which drives the rotating shaft 14 to rotate. The rotating shaft 14 rotates, which drives the rotating seat 7 to rotate, thereby opening the cover plate 6. At this time, the bucket body 1 can be loaded. After loading is completed, the output shaft of the drive motor 12 reverses, thereby realizing the flipping of the cover plate 6 and achieving the purpose of closing the bucket body 1 to prevent sand and gravel dust from scattering. The same applies during unloading.

[0043] During unloading, the rotation of the worm gear 21 drives the second worm wheel 20 to rotate, which in turn rotates the winding reel 19. The winding reel 19 can wind up the pull rope 15, which can pull the baffle 23 to move. The movement of the baffle 23 can open the atomizing nozzle 25, and the dust-suppressing water is injected into the flow chamber 24 through the water injection pipe 5 and the connecting hole 27. Finally, it is sprayed out through the atomizing nozzle 25 to achieve the purpose of atomizing dust suppression and prevent dust from scattering and affecting the working environment. Conversely, when the cover plate 6 flips, the baffle 23 can be attracted and reset under the action of the first magnetic plate 26, and the atomizing nozzle 25 is blocked again to prevent dust from entering the atomizing nozzle 25.

[0044] When disassembling and replacing the tooth tip 3, the sealing cover 4 is unscrewed, and the push rod 31 is pulled to the left and reset under the action of the spring 33. The push rod 31 is separated from the locking block 35, and the locking block 35 is magnetically attracted by the second magnetic plate 38, thus sliding out of the locking groove 36, so that the insertion rod 30 can be moved and pulled out of the through hole, so that the insertion plate 29 can be pulled out of the insertion groove 28, thus achieving the purpose of disassembling the tooth tip 3. Conversely, the tooth tip 3 can be fixedly installed with the tooth seat 2.

[0045] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
