In order to simulate this natural environment and promote the reproduction of the golden apple snail, people often design attachment tubes for golden apple snails to lay eggs. The attachment tube simulates the scene of golden apple snails laying eggs in the natural environment.

[0038] The welding assembly 3 includes a second welding gun 31 mounted on the outer wall of the rear side of the welding device body 1, a connecting rod 32 connected to the outer wall of the second welding gun 31 at one end, and a third welding gun 33 connected to the other end of the connecting rod 32 and symmetrically arranged with the second welding gun 31;

[0039] The first welding gun 2, the second welding gun 31 and the connecting rod 32 are configured with the same specifications. The first welding gun 2, the second welding gun 31 and the connecting rod 32 all include a fixed seat, a rotating shaft, a rotating arm and a welding head.

[0040] The rotating assembly 6 includes a bottom plate 61 mounted on the outer wall of the welding device body 1, a motor drive shaft 62 placed in the bottom plate 61, a main gear 63 connected to the output end of the motor drive shaft 62, a first mounting seat 64 connected to the outer wall of the main gear 63, a movable rod 65 connected to the first mounting seat 64, a second mounting seat 68 mounted on the outer wall of the bottom plate 61, a fixed rod 67 connected to the second mounting seat 68, and a universal joint 66 placed at the connection between the movable rod 65 and the fixed rod 67;

[0041] When it is necessary to weld two groups of pipes 8 relative to or vertically, the motor drive shaft 62 can be started by an external switch, so that the motor drive shaft 62 drives the main gear 63 to rotate, and the rotation of the main gear 63 drives the first mounting seat 64 connected thereto to rotate synchronously, and the first mounting seat 64 drives the movable rod 65 to rotate with the fixed rod 67 through the universal joint 66, that is, the movable rod 65 and the fixed rod 67 are connected through the universal joint 66, allowing the mounting plate 4 to rotate within the range of 0 to 90 degrees, and the mechanical limiter is integrated between the movable rod 65 and the universal joint 66 to ensure that the mounting plate 4 does not exceed the set angle limit, the first mounting seat 64 and the movable rod 65 drive the mounting plate 4 connected thereto to rotate, and the second mounting seat 68 and the fixed rod 67 drive the mounting plate 4 connected thereto to remain stationary, and the two groups of mounting plates 4 are rotated and adjusted to a vertical and straight parallel state according to needs, that is, the pipes 8 on the two groups of mounting plates 4 are driven to form a vertical and straight intersecting state;

[0042] It is worth noting that the input end of the motor drive shaft 62 is electrically connected to the output end of the external switch, the motor drive shaft 62 is placed in the bottom plate 61, and the outer end passes through the outer wall of the bottom plate 61 to be connected to the main gear 63, wherein the main gear 63 and the transmission assembly 7 are meshed with each other. Specifically, by electrically connecting the input end of the motor drive shaft 62 to the output end of the external switch, the start and stop of the motor can be controlled by the external switch, thereby realizing the driving of the transmission assembly 7. When the external switch is closed, current flows to the motor, driving the motor to start, so that the motor drive shaft 62 rotates, and then drives the main gear 63 to rotate. The motor drive shaft 62 is placed in the bottom plate 61, passes through the outer wall of the bottom plate 61 to be connected to the main gear 63, and the main gear 63 and the transmission assembly 7 are meshed with each other, so that the rotation of the motor can be transmitted to the transmission assembly through the main gear, thereby realizing the operation of the transmission assembly;

[0043] A group of mounting plates 4 are connected to the top of the first mounting seat 64 and the movable rod 65, and another group of mounting plates 4 are connected to the top of the second mounting seat 68 and the fixed rod 67, wherein the movable rod 65, the universal joint 66 and the fixed rod 67 are correspondingly provided with four groups. Specifically, by the combination of the movable rod 65, the universal joint 66 and the fixed rod 67, the flexible adjustment and positioning of the welding device can be realized. The universal joint 66 can adjust the movable rod 65 in the horizontal and vertical directions. The four groups are provided to ensure that the welding device has a stable support during operation and is not prone to shaking or tilting, thereby ensuring the stability and safety of the welding process;

[0044] The transmission assembly 7 includes a first driven wheel 71 and a second driven wheel 72 which are rotatably connected to the outer wall of the bottom plate 61 and meshed with the main gear 63, a third driven wheel 73 which meshes with the two driven wheels 72 and is rotatably connected to the outer wall of the bottom plate 61, a pulley 74 connected to the outer wall of the top end of the first driven wheel 71 and the third driven wheel 73, a belt 75 which is wound around the outer wall of the pulley 74 at one end, a rotating column 76 which is wound around the other end of the belt 75, a first bevel gear 77 connected to the outer wall of the top end of the rotating column 76, and a second bevel gear 78 connected to the first welding gun 2 and the welding assembly 3. The first driven wheel 71 and the second driven wheel 72 are connected to the main gear 63 through gear meshing and are connected to the outer wall of the bottom plate 61. The third driven wheel 73 meshes with the second driven wheel 72 and is rotatably connected to the outer wall of the bottom plate 61. Its size is equal to that of the first driven wheel 71 and the second driven wheel 72.

[0045] The two sets of rotating columns 76 are respectively connected to the outer wall of the welding device body 1 on one side of the first welding gun 2 and the welding assembly 3 through bearings;

[0046] When the main gear 63 rotates, the first driven wheel 71 and the second driven wheel 72 meshing with each other will be driven to rotate synchronously in the same direction. The second driven wheel 72 will drive the meshing third driven wheel 73 to rotate. The rotation direction of the third driven wheel 73 is opposite to that of the first driven wheel 71 and the second driven wheel 72. The first driven wheel 71 and the third driven wheel 73 both drive the belt pulleys 74 connected thereto to rotate. The two sets of belt pulleys 74 rotate in opposite directions. The two sets of belt pulleys 74 drive the rotating column 76 connected thereto to rotate through the belt 75. The rotation of the rotating column 76 drives the first bevel gear 77 to rotate. The rotation of the first bevel gear 77 drives the second bevel gear 78 meshing therewith to rotate. If the main gear 63 rotates to drive the two sets of pipes 8 to be in a vertical state, then as shown in FIG. Figure 2As shown, the second bevel gear 78 connected to the first welding gun 2 rotates to drive the rotating arm and the welding head of the first welding gun 2 to rotate downward and close to the vertical intersection for welding, and the second bevel gear 78 connected to the second welding gun 31 rotates to drive the rotating arm and the welding head to rotate upward, and the second welding gun 31 drives the rotating arm and the welding head on the third welding gun 33 to rotate upward synchronously through the connecting rod 32, away from the position of the pipe 8. If the main gear 63 rotates to drive the two groups of pipes 8 to intersect in a straight line horizontally, the second bevel gear 78 connected to the second welding gun 31 rotates to drive the rotating arm and the welding head to rotate downward, so that the second welding gun 31 and the third welding gun 33 both rotate downward to weld the two groups of pipes 8 in a parallel straight line state. At this time, the second bevel gear 78 connected to the first welding gun 2 rotates The rotation of the main gear 63 drives the rotating arm and the welding head of the first welding gun 2 to rotate upward; specifically, if the main gear 63 rotates to drive the two groups of pipes 8 to be in a vertical state, the second bevel gear 78 connected to the first welding gun 2 rotates to drive the rotating arm and the welding head of the first welding gun 2 to rotate downward to near the vertical intersection for welding, and at this time, the second bevel gear 78 connected to the second welding gun 31 rotates to drive the rotating arm and the welding head to rotate upward synchronously; if the main gear 63 rotates to drive the two groups of pipes 8 to be in a straight horizontal intersection state, the second bevel gear 78 connected to the second welding gun 31 rotates to drive the rotating arm and the welding head to rotate downward to weld the two groups of pipes 8 in a parallel straight state, and at this time, the second bevel gear 78 connected to the first welding gun 2 rotates to drive the rotating arm and the welding head of the first welding gun 2 to rotate upward synchronously.

[0047] It is worth noting that the first driven wheel 71 and the second driven wheel 72 are symmetrically arranged on the front and rear outer walls of the bottom plate 61, the first driven wheel 71, the second driven wheel 72 and the third driven wheel 73 are set to be equal in size, the first driven wheel 71 and the second driven wheel 72 rotate in the same direction, and the first driven wheel 71 and the third driven wheel 73 rotate in opposite directions. Specifically, by symmetrically arranging the first driven wheel 71 and the second driven wheel 72 on the front and rear outer walls of the bottom plate 61 and setting them to be equal in size, it can be ensured that the rotating component remains balanced during rotation and unnecessary vibration is reduced. and shaking, thereby improving the stability of the welding device, the first driven wheel 71 and the second driven wheel 72 rotate in the same direction, which can ensure that the rotation direction of the rotating assembly is consistent with the rotation direction of the transmission assembly, thereby effectively driving the movement of the transmission assembly and realizing the normal operation of the welding device, the first driven wheel 71 and the third driven wheel 73 rotate in opposite directions to each other, which can ensure that the movement directions of the two ends of the transmission assembly are opposite, thereby realizing the bidirectional movement of the transmission assembly, which is very important for ensuring that the welding device can flexibly adapt to different welding conditions and realize the requirements of different welding angles and directions;

[0048] The second bevel gear 78 is fixed on the rotating shaft of the first welding gun 2 and the second welding gun 31 respectively. The second bevel gear 78 and the first bevel gear 77 are set to the same size. The two sets of first bevel gears 77 rotate in opposite directions. Specifically, when it is necessary to vertically weld two sets of pipes, the main gear 63 rotates the arm and welding head of the first welding gun 2 downward to near the vertical intersection for welding through the rotating assembly 6 and the transmission assembly 7. When it is necessary to horizontally intersect the two sets of pipes, the main gear 63 rotates the arm and welding head of the second welding gun 31 and the third welding gun 33 downward through the rotating assembly 6 and the transmission assembly 7, so that both sets of welding guns face the intersection, thereby realizing the welding of horizontally intersecting pipes.

[0049] In summary, the design of the rotating assembly 6 and the transmission assembly 7 needs to match the function and workflow of the welding device. The rotating assembly 6 is usually used to control the movement of the welding head, while the transmission assembly 7 is responsible for adjusting the angle or direction of the welding head. Their linkage needs to ensure that the welding device can be flexibly adjusted and positioned in different directions to meet the needs of different welding tasks. Although there are other possible linkage structures that can achieve similar functions, the selection of the linkage structure of the rotating assembly 6 and the transmission assembly 7 may be based on the consideration of factors such as its design simplicity, reliability and applicability. The advantages include:

[0050] Simplicity: This linkage structure is relatively simple, easy to design and implement, and reduces manufacturing and maintenance costs.

[0051] Stability: The linkage design of the rotating assembly 6 and the transmission assembly 7 has been fully considered and has good stability and reliability, and can meet the needs of long-term, high-intensity work.

[0052] Flexibility: This linkage structure can flexibly realize the movement and rotation of the welding head in the horizontal and vertical directions, which is suitable for a variety of different welding tasks and work scenarios.
