[0042] The first conveyor belt 17 can transmit the power of the driving wheel 5 to the driven wheel 16, and drive the reciprocating screw 18 to rotate, so that the second slider 19 pushes the welding slag into the first collecting box 2 by moving back and forth, and the bottom of the first collecting box 2 can be adaptively provided with rollers on the side wall of the workbench 1, so that it can move by rolling friction, which can effectively reduce friction damage and thus increase the service life of the device. The above-mentioned roller setting is an obvious conventional technical means for technical personnel in this field, and will not be described in detail here, and there are no corresponding drawings, but it does not affect the effective implementation of the technical solution of the present invention.

[0043] refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 The adjustable welding equipment for installing steel components of the out-of-stock equipment also includes a smoke treatment mechanism 21, which includes a cover body 22 and a rotating and telescopic component 23. Both sides of the bottom end of the cover body 22 are fixedly connected to the panel through columns, and a welding area connected to the welder 14 is formed between the cover body 22 and the panel.

[0044] The rotating and telescopic assembly 23 includes a first sleeve 24, and the first sleeve 24 and the driving wheel 5 are connected to each other through a second conveyor belt 25 arranged parallel to the first conveyor belt 17.

The outer wall of the second sleeve 26 penetrates the cover body 22 and extends to the first bevel gear 27 and the second bevel gear 28 in sequence, and the first bevel gear 27 and the second bevel gear 28 keep rotating in the same direction.

[0045] A welding slag collection mechanism 15 is provided. When welding is carried out on the steel components of the off-line equipment, welding slag is generated due to metal oxidation and falls into the notch in the workbench 1. In order to push it into the first collection box 2, the first motor 4 can transmit power to the reciprocating screw 18 through the first conveyor belt 17 after being started. With the help of the spiral transmission, the pushing plates 20 at both ends push the welding slag into the first collection box 2 at the same time. In addition, the top of the pushing plate 20 is triangular in shape, which can effectively prevent the welding slag from falling onto the pushing plate 20, thereby causing incomplete cleaning, thereby ensuring the safety of the working environment.

[0046] The outer wall of the first bevel gear 27 is meshed with a third bevel gear 30 fixed on the second screw shaft 29, and a third slider 31 is spirally driven on the second screw shaft 29. One end of the third slider 31 is connected to a fixing rod 33 through a cross beam 32, and the top of the fixing rod 33 is connected to equidistantly distributed top rods 34 through an inclined plate.

The smoke particles are filtered through the purification of the water body, and the impurity particles floating on the water body will be pushed to the third collection box 45 for collection under the action of the scraper 44. In order to prevent the filter holes 36 from being blocked during the long-term operation of the filter plate 35, the particles can be ejected by moving the push rod 34 up and down, and slide down into the second collection box 37 under the gravity of the particles themselves.

[0048] Specifically, one end of the filter plate 35 is connected to a second collecting box 37 near the side wall of the cover body 22, and the connection between the filter plate 35 and the cover body 22 is connected by locking and fixing with a positioning pin. The outer wall of the second bevel gear 28 is meshed with a fourth bevel gear 39 fixed on the first rotating shaft 38, and the first rotating shaft 38 and the second rotating shaft 40 are connected by a third conveyor belt 41. One end of the second rotating shaft 40 passes through the cover body 22 and is connected to the third rotating shaft 43 by a fourth conveyor belt 42.

[0049] A smoke and dust treatment mechanism 21 is provided, and the smoke and dust will enter the guide channel through the filter plate 35, and under the action of the fan 47, the smoke and dust will be transported to the water tank 49 to contact the water body, and the smoke and dust particles will be effectively purified and cleaned through the filtering effect of the filter plate 35 and the water body. At the same time, after the first motor 4 is started, it can be transmitted to the rotating telescopic component 23 through the second conveyor belt 25, so that the first bevel gear 27 and the second bevel gear 28 on the second sleeve 26 can be driven to rotate in the same direction. Under the action of mechanical transmission, the second screw shaft 29 can drive the top rod 34 on the crossbeam 32 to move up and down and Impurities in the filter holes 36 are removed, and the particles can slide into the second collection box 37 for collection under their own weight. The highly staggered filter plates 35 can effectively utilize space resources and purify the smoke particles to the greatest extent. During the rotation of the first rotating shaft 38, the third conveyor belt 41 can drive the second rotating shaft 40 and the fourth conveyor belt 42 on the third rotating shaft 43 to rotate in a circle, and remove the particles floating on the water tank 49 into the third collection box 45, which effectively protects the environment and prevents smoke gas from being directly discharged into the atmosphere, which is beneficial to environmental protection.

[0050] The third conveyor belt 41 and the fourth conveyor belt 42 are kept vertically arranged, the second rotating shaft 40 and the third rotating shaft 43 are arranged at the same height on the cover body 22, the fourth conveyor belt 42 is equipped with scrapers 44 that are equidistantly distributed, and the outside of the scraper 44 is provided with a third collecting box 45 placed on the cover body 22, a partition 46 is fixedly installed on the side wall of the cover body 22, a fan 47 is installed on the top of the partition 46, guide channels are formed at both ends of the fan 47, and one end of the guide channel is connected to the water tank 49 on the side wall of the cover body 22 through a U-shaped tube 48, rollers are installed around the bottom of the workbench 1, the first collecting box 2 is a pull-out movable arrangement, and a pushing handle is fixedly installed on the outer wall of the first collecting box 2.

[0051] The third conveyor belt 41 and the fourth conveyor belt 42 are kept vertically arranged, which can not only realize the reversal adjustment of the power, but also can be adaptively rotated and adjusted in accordance with the height of the water tank 49 itself. At the same time, the two conveyor belts are arranged in parallel, so that structural interference between the transmission parts can be prevented when the power is transmitted stably, thereby improving the working stability of the device. The design of the U-tube 48 allows the gas to pass smoothly when passing through, and when the liquid tries to be sucked back, due to the height difference of the liquid in the U-tube 48, a resistance will be formed to prevent the liquid from continuing to be sucked back into the reaction device.

[0052] A rotating and telescopic assembly 23 is provided to ensure that the cover body 22 can perform normal horizontal movement and can effectively transmit power to the smoke treatment mechanism 21. By providing a first sleeve 24 and a telescopic and movable second sleeve 26, in cooperation with the protrusion on the first sleeve 24, the second sleeve 26 can move freely and transmit the rotational power of the first sleeve 24 to the second sleeve 26, so that the entire transmission part can rotate normally, thereby improving the safety of the device.
