Description

Technical Field

[0001] The utility model relates to the field of auger spiral production, and more specifically, to a smoke and dust collection device based on auger spiral welding. Background Art

[0002] The auger screw is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Its working principle is that the rotating spiral blade pushes the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor casing to the material. During the production process of the auger screw, the spiral blade and the shaft need to be welded.

[0003] A large amount of welding smoke is generated during the welding of the auger spiral. These smoke contains a variety of harmful substances, such as metal oxides, harmful gases and tiny particles, so they need to be collected to ensure the health of the workers. At present, smoke adsorption devices are commonly used to adsorb and collect the smoke from the welding of the auger spiral. However, the position of the adsorption port of the traditional smoke adsorption device is fixed, and the diffusion of smoke is uncertain and random, and may drift in all directions. If the suction port is fixed, it is impossible to capture the smoke that deviates from the fixed position in a timely and effective manner, resulting in a large amount of smoke escaping and unable to be inhaled, resulting in poor collection effect.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a smoke collection device based on auger spiral welding. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a smoke collection device based on auger spiral welding.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smoke collection device based on auger spiral welding, comprising a smoke adsorption device and a base, a lifting device is installed on the top of the base, and the lifting platform is lifted and lowered by the lifting device, and a swing assembly is installed on the top of the lifting platform, and the welding smoke adsorption device is installed on the swinging part of the swing assembly to expand the adsorption range of the welding smoke adsorption device.

[0007] Preferably, the swing assembly includes a bearing fixed to the head of the lifting platform, a rotating rod is fixedly connected to the inner ring of the bearing, the head of the rotating rod is fixedly connected to a frame plate, the surface of the lifting platform located in front of the bearing is fixedly connected to a motor for driving the rotating plate to rotate, a square plate is welded to the head of the rotating plate, and a cylindrical block that can move inside the frame plate is installed on the surface of the square plate, the head of the rotating rod is fixedly connected to the swing platform, and the smoke adsorption device is installed on the top of the swing platform.

[0008] Preferably, the length of the rotating plate is adjustable, so that the swing amplitude of the welding fume adsorption device can be adjusted. The staff can make adjustments according to the actual fume generated by welding, which is more practical.

[0009] Preferably, the rotating plate includes an outer frame plate, the inner plate is slidably connected to the inner plate inside, a through hole is opened at the top of the outer frame plate, and a plurality of screw holes are arranged in a horizontal array on the front and rear sides of the top of the inner plate, and the square plate is welded to the end of the inner plate away from the outer frame plate.

[0010] Preferably, the lifting device is a hydraulic jack, which is easy to operate.

[0011] Preferably, the base is made of cast iron material to improve the stability of the base support and prevent the device from tipping over.

[0012] Preferably, universal wheels with locking function are installed around the bottom end of the base to facilitate the movement of the device.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model drives the lifting platform to move up and down through the lifting device, thereby driving the smoke adsorption device to move up and down, so as to adjust the height of the smoke adsorption device, so that the height of its dust suction port is flush with the welding height on the auger spiral body. When absorbing smoke, the smoke adsorption device can be driven to swing back and forth by the swing component to increase the adsorption range of its dust suction port, thereby improving the collection effect of smoke, so as to solve the problem that the dust suction port in the background technology is fixed, and the smoke that deviates from the fixed position cannot be captured in time and effectively, resulting in a large amount of smoke escaping and cannot be inhaled, thereby resulting in poor collection effect;

[0015] 2. The length of the rotating plate of the utility model can be adjusted to adjust the radius of the rotating area of ​​the cylindrical block, so that the swing amplitude of the welding fume adsorption device can be adjusted. The staff can make adjustments according to the actual fume generated by welding, which is more practical;

[0016] 3. The utility model is equipped with universal wheels with locking function under the base to facilitate the device to change position continuously. The base material is cast iron, which has high density and is heavier than general materials under the same volume, thereby stably supporting the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When in use, the lifting platform 4 is driven up and down by the lifting device 3, thereby driving the smoke adsorption device 1 to move up and down to adjust the height of the smoke adsorption device 1, so that the height of its dust suction port is flush with the welding height on the auger spiral. When absorbing smoke, the smoke adsorption device 1 can be driven to swing back and forth by the swing component 5 to increase the adsorption range of its dust suction port, thereby improving the collection effect of smoke. The lifting device 3 is preferably a hydraulic jack for easy control.
