Description
Technical Field
[0001] This application relates to the field of earthwork engineering, and more specifically, to a welding device for excavator buckets used in earthwork construction machinery. Background Technology
[0002] Earthwork engineering is one of the major engineering processes in building construction, encompassing all aspects of earthwork (excavation, filling, transportation, drainage, and dewatering). In civil engineering, earthwork includes: site leveling, roadbed excavation, civil defense excavation, ground filling, roadbed construction, and foundation pit backfilling. A reasonable construction plan should be arranged, avoiding scheduling during the rainy season as much as possible. Furthermore, to reduce earthwork construction costs, the principle of minimizing or eliminating the occupation of farmland and arable land, and facilitating land reclamation, should be followed. A reasonable allocation plan for earthwork should be developed and coordinated in a comprehensive manner.
[0003] Patent document CN212599802U discloses a welding device for excavator buckets, including a base. Foot feet are fixedly connected to the left and right sides of the base bottom. Telescopic rods are fixedly connected to the center of the base top near the left and right sides. A base plate is fixedly connected to the top of the telescopic rods. Positioning rods are fixedly connected to the left and right sides of the base top. A threaded rod is movably connected to the side of the positioning rod furthest from the center of the base. A placement plate is fixedly connected to the side of the threaded rod closest to the center of the base. Connecting rods are fixedly connected to the left and right sides of the base top. A rotating rod is movably connected to the side of the connecting rod furthest from the center of the base. A welding torch is fixedly connected to the side of the rotating rod closest to the center of the base. Fans are fixedly connected to the left and right sides of the base top.

It is necessary to remove the fixation and then adjust it, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1
[0023] See Figures 1-4 This embodiment provides a welding device for excavator buckets used in earthmoving construction machinery, including a fixed plate 1 for supporting and fixing the overall structure. A support leg 2 is fixedly connected to the bottom of the fixed plate 1, and a rotating clamping device is fixedly connected to the upper end of the fixed plate 1. The rotating clamping device includes two mounting plates 31, which are fixedly connected to the upper end of the fixed plate 1. A motor A32 is fixedly connected to the upper end of the fixed plate 1. A transmission rod 33 is fixedly connected to the output end of the motor A32. The transmission rod 33 movably passes through the mounting plate 31. A drive wheel 34 is fixedly sleeved on the outer wall of the transmission rod 33. A transmission belt 35 is wound around the outer wall of the drive wheel 34. A driven wheel 36 is drivenly connected to the inner side of the upper end of the transmission belt 35. A rotating shaft 37 is fixedly connected to the middle of the driven wheel 36. One end of the rotating shaft 37 passes through the mounting plate 31 through a bearing. A connecting plate 38 is fixedly connected to the end of the rotating shaft 37 away from the driven wheel 36. A cylinder 39 is fixedly connected to the lower end of the connecting plate 38, and a clamping plate 310 is fixedly connected to the other end of the cylinder 39. A welding device is provided at the upper end of the fixed plate 1. The welding device includes a vertical plate 51, which is fixedly connected to the upper end of the fixed plate 1. A welding box 52 is fixedly connected to the outer wall of the vertical plate 51. A welding rod 53 is fixedly connected to one end of the welding box 52, and a welding head 54 is fixedly connected to the other end of the welding rod 53 for actual welding operations.
[0024] In practical use, the above-mentioned equipment is first placed on the upper end of the placement plate 45. Then, the cylinder 39 is started to drive the clamping plate 310 closer to the center, thereby fixing the excavator bucket. When the direction needs to be adjusted, the motor A32 is started to drive the transmission rod 33 to rotate, which in turn drives the drive wheel 34 to rotate. Under the transmission action of the transmission belt 35, the driven wheel 36 can be driven to rotate, which in turn drives the rotating shaft 37 to rotate. The connecting plate 38 will then rotate, thereby driving the excavator bucket to rotate through the cylinder 39 and the clamping plate 310. In addition, the excavator bucket can be moved left and right by the cooperation of two cylinders 39. Example 2
[0025] See Figures 1-4 Based on Embodiment 1, a receiving device is provided at the upper end of the fixed plate 1. The receiving device includes a C-shaped plate 41, which is fixedly connected to the upper end of the fixed plate 1. A motor B42 is fixedly connected to the upper end of the C-shaped plate 41. A threaded rod A43 is fixedly connected to the output end of the motor B42. A threaded sleeve rod A44 is threadedly connected to the outer wall of the threaded rod A43. A placement plate 45 is fixedly connected to the top of the threaded sleeve rod A44. A threaded rod B46 is fixedly connected to the upper end of the C-shaped plate 41. A threaded sleeve rod B47 is threadedly connected to the outer wall of the threaded rod B46. A gear A48 is fixedly sleeved on the outer wall of the threaded rod A43, and a gear B49 is fixedly sleeved on the outer wall of the threaded rod B46. Gears A48 and B49 mesh. The top of the threaded sleeve rod B47 is fixedly connected to the bottom of the placement plate 45. The middle part of the C-shaped plate 41 is higher than the transmission rod 33.
[0026] In practical use, when the digging bucket on the upper end of the placement plate 45 needs to be rotated after it is fixed, the motor B42 is started to drive the threaded rod A43 to rotate. At the same time, the gear A48, which is fixedly connected to the outer wall of the threaded rod A43, will also rotate, which will drive the gear B49 to rotate, and then drive the threaded rod B46 to rotate. Since the threads of the threaded rods A43 and B46 are opposite in direction, the threaded sleeves A44 and B47, which are respectively threaded to their outer walls, will descend, which will drive the placement plate 45 to descend, thereby moving the placement plate 45 away from the digging bucket and providing a range of motion for rotation.
[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
