Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery component repair welding connection, in particular to a multi-angle welding machine for agricultural machinery component repair with strong applicability. Background Art

[0002] Traditional Chinese medicine cultivation refers to the scientific and standardized cultivation and management of medicinal plants under the guidance of traditional Chinese medical theory. This process not only adheres to natural growth patterns but also integrates agricultural techniques with the essence of Traditional Chinese Medicine (TCM). Its goal is to cultivate high-quality, highly effective Chinese herbal medicines, thereby ensuring the sustainable utilization of TCM resources and the healthy development of the TCM industry. The cultivation process involves trenching and sowing, which currently requires the coordination of multiple agricultural tools, resulting in low efficiency.

[0003] Publication number CN119769225A is a slotting and sowing device for Chinese medicinal herb planting, which includes a tractor, a welded base, a coupler, a slotting and sowing device, and a soil filling device. The welded base is welded to the back of the tractor, and two couplers are respectively welded to the front of the welded base and the tail end of the slotting and sowing device. Two traction rod locking pins are connected together, and the soil filling device is plugged into the front end of the tractor. The present invention designs the device structure according to the steps of Chinese medicinal herb planting, changes the previous mode of multiple agricultural implements working together, combines slotting and sowing, backfilling and other processes together, improves the efficiency of Chinese medicinal herb planting, and reduces production costs.

[0004] In the above technical solution, corresponding welding bases, brackets and other components are provided to facilitate welding of the coupler, which facilitates the subsequent installation of corresponding agricultural machinery components. For example, when using large agricultural machinery for land preparation operations, the land preparation equipment can be connected to the agricultural machinery through welding through the bracket to ensure the firmness of the connection. However, in actual operation, the welding between the above components needs to be carried out in the production and professional maintenance workshops through the cooperation of multiple components, such as using clamping and lifting equipment, positioning equipment, and then manual or automatic welding equipment for welding operations.

[0005] When agricultural machinery is operating in the fields, if the bracket breaks, the agricultural machinery and the broken bracket need to be transported to the maintenance workshop and welded and fixed with corresponding equipment. Or it is not convenient for farmers to connect and fix new agricultural machinery or brackets by themselves after purchasing them, so improvements are needed. Summary of the Invention

At the same time, the automation components used in this application are all installed with corresponding supporting components and control components on the movable base 14 to ensure that the device is easy for the staff to operate.

[0030] In this embodiment, a moving mechanism is installed on the upper end of the movable base 14, and a supporting positioning mechanism is provided on the moving mechanism. The position of the supporting positioning mechanism can be adjusted through the moving mechanism, and the position height of the bracket component and the distance between the bracket component and the agricultural machinery can be controlled, so as to facilitate the preliminary positioning of the bracket component and the agricultural machinery and facilitate subsequent welding operations.

After the position of the positionable rail moving frame 12 is adjusted, the brake stop component can be fixed to the rail member 13 or the movable base 14 to prevent the positionable rail moving frame 12 from shaking, thereby ensuring the stability of the bracket component. The positionable rail moving frame 12 is connected to the support positioning mechanism, and the general position of the bracket component can be adjusted by the positionable rail moving frame 12, and the corresponding abutment can be completed later by the support positioning mechanism.
