[0002] Submerged arc welding machines are welding machines that use an electric arc to burn under a layer of flux for welding. Although existing submerged arc welding machines can control the amount of flux discharged according to needs, this is generally achieved by adjusting the size of the conveying space in the conveying pipe. However, since the flux is a solid particle, it is prone to blockage when the conveying space is reduced, which can lead to interruption or uneven delivery of flux, resulting in discontinuity and affecting the welding effect. Therefore, there is an urgent need for a welding machine that can discharge flux in a quantitative manner. Utility Model Content

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a submerged arc welding vehicle 1, a feed box 2, a flux storage tank 18, and a quantitative control valve 19. The feed box 2 is fixedly installed on the submerged arc welding vehicle 1. The flux storage tank 18 is located on the right side of the feed box 2 on the submerged arc welding vehicle 1. A quantitative control valve 19 is installed on the conveying pipe between the flux storage tank 18 and the feed box 2. A fixed frame 12 is fixedly installed on the submerged arc welding vehicle 1. A collection hopper 13 is provided at the lower end of the fixed frame 12. During the movement operation of the submerged arc welding vehicle 1, the collection hopper 13 can clean and collect excess flux. A connecting frame 14 is fixedly installed on the upper part of the collection hopper 13. The connecting frame 14 is movably sleeved on the fixed frame 12. Locking screws 15 are threadedly inserted into the front and rear side walls of the connecting frame 14, with one end of the locking screw 15 movably inserted into a groove on the side wall of the connecting frame 14. Through the cooperation of the locking screw 15 and the connecting frame 14, the collection hopper 13 can be easily installed and removed from the fixed frame 12, facilitating the removal of excess flux collected in the collection hopper 13. Positioning strips 16 are fixedly installed on the front and rear inner side walls of the connecting frame 14, located above and below the locking screws 15. The positioning strips 16 are movably positioned in the strip-shaped grooves on the side walls of the connecting frame 14. The positioning strips 16 not only provide auxiliary positioning for the connecting frame 14 on the fixed frame 12 but also improve the installation stability of the connecting frame 14.
[0025] It also includes:
[0026] The control discharge cylinder 3 is fixedly installed at the discharge port below the fixed material box 2. The front side of the control discharge cylinder 3 is provided with a discharge pipe 4, which is fixedly installed on the submerged arc welding vehicle 1. The opening of the side wall of the control discharge cylinder 3 is provided with an observation window 17, through which the operator can observe the specific discharge situation inside the control discharge cylinder 3. The bottom of the control discharge cylinder 3 is set with an inclined structure, which can provide discharge guidance for the flux inside the control discharge cylinder 3 and avoid flux residue in the control discharge cylinder 3.
[0027] The internal threaded cylinder 5 is fixedly installed at the lower part of the control discharge cylinder 3. A threaded rod 6 is inserted through the internal threaded cylinder 5 by the threaded rotation. The lower end of the threaded rod 6 passes through the internal threaded cylinder 5 and is fixedly fitted with an adjusting handle 7. A support rod 8 is fixedly installed at the upper end of the threaded rod 6 and is movably inserted through the control discharge cylinder 3.
[0028] The material stop block 9 is rotatably mounted on the upper end of the support rod 8 via a bearing. The material stop block 9 has a frustum-shaped structure. The fixed material box 2 is provided with an anti-blocking mechanism 10 connected to the material stop block 9. The fixed material guide plate 11 is movably sleeved on the material stop block 9 and is fixedly mounted in the control discharge cylinder 3.
[0029] The anti-clogging mechanism 10 includes:
[0030] A geared motor 10-2 is fixedly installed on the upper part of the fixed material box 2. A rotating rod 10-3 is rotatably installed in the fixed material box 2 via bearings. The output shaft of the geared motor 10-2 is fixedly connected to the upper end of the rotating rod 10-3. Several crossbars 10-4 are fixedly installed on the annular side wall of the rotating rod 10-3. The crossbars 10-4 can rotate with the rotating rod 10-3 in the fixed material box 2 to disperse the flux in the fixed material box 2 and prevent the flux from clumping and causing blockage.
[0031] The drive bar 10-1 consists of several bars, which are distributed with equal rounded corners on the annular sidewall of the rotating rod 10-3. The lower ends of both the drive bar 10-1 and the rotating rod 10-3 are movably inserted into the slots opened on the stop block 9. The rotating rod 10-3 can drive the stop block 9 to rotate through the drive bar 10-1, thus preventing flux from causing blockage in the adjustable gap between the stop block 9 and the fixed guide plate 11.
[0032] When using this invention, the flux in the flux storage tank 18 is transported to the fixed material tank 2 through the conveying pipe. The quantitative control valve 19 controls the amount of flux stored in the fixed material tank 2 for each welding operation. During operation, the submerged arc welding vehicle 1 moves at a constant speed and performs welding. The flux in the fixed material tank 2 falls into the controlled discharge cylinder 3 through the gap between the baffle block 9 and the fixed guide plate 11. The flux in the controlled discharge cylinder 3 then falls through the discharge pipe 4 to the desired welding position. During this process, the reduction motor 10-2 can be activated, driving the rotating rod 10-3. Rotating slowly, the rotating rod 10-3 drives the crossbar 10-4 to rotate within the fixed material box 2, preventing flux clumps from forming in the fixed material box 2. At the same time, the rotating rod 10-3 can also drive the baffle block 9 to rotate via the drive bar 10-1, preventing flux from clogging the gap between the baffle block 9 and the fixed guide plate 11. When it is necessary to change the flux output, the adjusting handle 7 can be rotated, which drives the threaded rod 6 to rotate, thereby adjusting the height of the support rod 8 and the baffle block 9, thus changing the size of the gap between the baffle block 9 and the fixed guide plate 11, and realizing the flux output control of the submerged arc welding vehicle 1 in the working state.
[0033] Compared with the prior art, the beneficial effects of this utility model are:
[0034] 1. By cooperating with the internal threaded cylinder 5, threaded rod 6, adjusting handle 7 and support rod 8, the size of the discharge gap between the baffle block 9 and the fixed guide plate 11 can be adjusted, thereby adjusting the amount of flux discharged.
[0035] 2. With the cooperation of the anti-blocking mechanism 10, the geared motor 10-2 can drive the rotating rod 10-3 to rotate, which can not only make the crossbar 10-4 stir the flux to avoid the flux from clumping, but also make the drive bar 10-1 drive the baffle block 9 to rotate, so as to prevent the flux from getting stuck in the discharge gap between the baffle block 9 and the fixed guide plate 11 and causing blockage.
[0036] 3. During the mobile operation of the submerged arc welding vehicle 1, the collection bucket 13 can clean and collect excess flux;
[0037] 4. By cooperating with the locking screw 15 and the connecting frame 14, the collection hopper 13 can be easily disassembled and assembled on the fixed frame 12, so as to remove the excess flux collected in the collection hopper 13.
[0038] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
