Description

Technical Field

[0001] This utility model relates to the field of harvester parts processing technology, specifically a header welding device. Background Technology

[0002] A combine harvester is an integrated machine for harvesting crops. It completes harvesting and threshing in one go, collects the grains into a storage bin, and then transports the grain to a transport vehicle via a conveyor belt. Manual harvesting is also possible, where the stalks of crops such as rice and wheat are laid out in the field and then picked up and threshed by grain harvesting machinery. Welding equipment is required during the processing of the combine harvester's header.

[0003] The prior art patent document CN117206682A discloses a handheld laser welding device, including a main unit and a welding torch for welding a weld formed close to the workpiece. The welding torch is connected to a gas pipe supplying shielding gas. The welding torch has a nozzle that provides a channel for the laser and shielding gas supplied by the main unit. The nozzle has a built-in flow guiding structure. Through the flow guiding structure, the shielding gas is guided in sections. The velocity difference between the high-pressure and low-pressure zones blocks welding slag between the weld point and the unwelded weld, and guides the welding slag flying towards the weld to both sides. Furthermore, a portion of the airflow in the high-pressure zone is swept along the weld towards the unwelded direction, and compressed at the weld location to generate an upward airflow, pushing the welding slag drifting towards the weld upwards and being blown away by the airflow along the weld direction, preventing the welding slag from falling onto the weld surface.

[0004] Although the device has many beneficial effects, it still has the following problems: It lacks mobility, requiring workers to move it during use, which undoubtedly increases their workload and wastes their time. Furthermore, it cannot effectively adjust the contact height between the device and the ground, causing it to shake when encountering uneven or potholed surfaces, hindering welding work. Therefore, we propose a cutting table welding device to solve these problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues mentioned above, such as the lack of mobility requiring manual handling for operation, which increases workload and wastes time, and the inability to effectively adjust the ground contact height, causing the equipment to shake and hinder welding work when encountering uneven or potholed surfaces, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a cutting table welding device. The device can be moved using the moving wheels, saving workers the time of manually carrying the equipment and improving their work efficiency. The damper facilitates the pressure relief plate, which in turn drives the sliding sleeve and shaft to begin pressure relief. This, in turn, causes the shaft to drive the moving wheels to begin pressure relief, while the sliding sleeve drives the sliding plate to begin pressure relief. The sliding plate then drives the spring to begin pressure relief, effectively mitigating the swaying force caused by bumpy roads during movement and improving the stability of the device.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a cutting table welding device, including:

[0035] Please see Figures 1-5 This embodiment of a cutting table welding device includes a fixed base 1 and a base 6. The top of the fixed base 1 is fixedly connected to a welding device 2 by a fixing bolt. The left side of the welding device 2 is fixedly connected to a welding head 3. The center of the top of the inner cavity of the base 6 is fixedly connected to a damper 13 by a locking bolt. The bottom of the damper 13 is fixedly connected to a pressure relief plate 12. The bottom of the pressure relief plate 12 is fixedly connected to a shaft 5. The bottom of the shaft 5 extends through the base 6 and is fixedly connected to a moving wheel 4. Both sides of the pressure relief plate 12 are fixedly connected to sliding sleeves 9. One side of the sliding sleeve 9 is fixedly connected to a sliding plate 10. The top of the sliding plate 10 is fixedly connected to a spring 8 by a welding bolt.

[0036] It is worth noting that, in order to improve the stability of the movement of the equipment, specifically, cylinders 18 are fixedly connected to both sides of the bottom of the inner cavity of the fixed base 1, and push plates 17 are fixedly connected to the top of the cylinders 18. Connecting rods 15 are fixedly connected to both the surface and the back of the push plates 17. The surface of the connecting rods 15 extends through to the outside of the fixed base 1 and is fixedly connected to a mounting plate 14. One side of the mounting plate 14 is fixedly connected to the back of the base 6. Through the cylinders 18, the push plates 17 can be pushed to move, thereby causing the push plates 17 to drive the connecting rods 15 to move. This enables the connecting rods 15 to drive the base 6 to move, which can effectively adjust the height of the fixed base 1 in contact with the ground, reduce the shaking force of the welding equipment 2, and improve the stability of the movement of the equipment.

[0037] Next, in order to facilitate the disassembly and assembly of the base 6, specifically, a first screw hole is provided on the back of the base 6, and a second screw hole is provided around the surface of the mounting plate 14. The inner cavities of the first screw hole and the second screw hole are threaded with mounting bolts 16. Through the cooperation of the mounting plate 14 with the first screw hole and the second screw hole, it is easy to disassemble and assemble the base 6.

[0038] Meanwhile, in order to improve the sliding process of the push plate 17, specifically, both sides of the inner cavity of the fixed base 1 are provided with sliding grooves, and both sides of the push plate 17 are slidably connected to the inner cavity of the sliding grooves. Through the sliding grooves, both sides of the push plate 17 can slide in the inner cavity of the sliding grooves, thereby improving the stability of the sliding of the push plate 17.

[0039] Furthermore, in order to improve the stability of the sliding sleeve 9, specifically, a sliding rod 11 is fitted inside the sliding sleeve 9. Both ends of the sliding rod 11 are fixedly connected to the inner wall of the base 6. Through the sliding rod 11, the sliding sleeve 9 can slide on its surface, thereby improving the stability of the sliding sleeve 9.

[0040] It is worth noting that, in order to improve the smoothness of the sliding of the skateboard 10, specifically, limit grooves are opened on both sides of the inner cavity of the base 6. One side of the skateboard 10 is slidably connected to the inner cavity of the limit groove. Through the limit groove, the side of the skateboard 10 can slide in its inner cavity, which improves the stability of the sliding of the skateboard 10.

[0041] Finally, in order to protect the welding equipment 2, specifically, a heat dissipation vent 7 is provided on the back of the welding equipment 2, and a dustproof net is provided on the surface of the heat dissipation vent 7. The dustproof net can play a role in blocking and preventing dust.

The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] The welding equipment 2 mentioned in the text can be found in the welding device in patent number CN117206682A.

[0045] Combination Figures 1-5 The specific usage process of the cutting table welding device of this embodiment is as follows:

[0046] 1. Based on actual usage, the user first holds the handle and pushes the device to move using the moving wheels 4. When the device encounters bumpy roads during movement, it is prone to shaking. The moving wheels 4 drive the shaft 5 to start easing pressure, which in turn drives the pressure relief plate 12 to start easing pressure. The pressure relief plate 12 then drives the sliding sleeve 9 and damper 13 to start easing pressure simultaneously. The sliding sleeve 9 drives the sliding plate 10 to start easing pressure, which in turn drives the spring 8 to start easing pressure. This effectively reduces the shaking force caused by bumpy roads during movement of the moving wheels 4, improving the stability of the device's movement.

[0047] 2: Secondly, in order to reduce the shaking force of welding equipment 2 and the contact height between the fixed base 1 and the ground, the user starts the cylinder 18 through the external controller. The cylinder 18 facilitates the movement of the push plate 17, which in turn drives the connecting rod 15 to move. The connecting rod 15 then drives the base 6 to move, which can effectively adjust the contact height between the fixed base 1 and the ground and reduce the shaking force of welding equipment 2.

[0048] 3: Finally, the user starts the welding equipment 2, then holds the welding head 3 and welds the harvester header.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
