DETAILED DESCRIPTION
[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0019] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.
[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0021] Figures 1-4 Shown is a schematic diagram of the entire structure of a dust collector dust removal device of the utility model, please refer to Figures 1-4 , a dust collector unloading device in this embodiment includes a fan main cabin 100, one end of the fan main cabin 100 is provided with a fan drive unit, namely a drive motor 110, the upper end of the fan main cabin 100 is connected to a feed hopper 200, and the lower end of the fan main cabin 100 is connected to a discharge box 300, and the inner side of the discharge box 300 is provided with staggered dust-blocking inclined plates 310 from top to bottom, and a spiral push rod 320 is laterally provided at the lower end of the inner side of the discharge box 300, and a discharge port 3001 is provided on one side of the bottom of the discharge box 300 and is located below the end of the spiral push rod 320, and a rotating drive component 400 is also provided on the outer side of the discharge box 300, which is linked with the drive motor 110 and drives the spiral push rod 320 to rotate. A main shaft 120 is rotatably installed in the center of the main cabin 100 of the fan, and one end of the main shaft is connected to the output shaft of the drive motor 110. A plurality of blades 130 are fixed on the outer side of the main shaft 120 and are located inside the main cabin 100 of the fan. When in use, the drive motor 110 can drive the plurality of blades 130 to rotate rapidly through the main shaft 120, thereby generating a rotary push airflow, and sucking the dust in the dust collector into the discharge box 300 through the feed hopper 200. This is a commonly used technical means in this field and will not be elaborated in detail.
[0022] The inner bottom of the discharge box 300 also has an arc-shaped material guide channel 3002 that matches the spiral push rod 320, and the bottom of one end of the arc-shaped material guide channel 3002 is vertically connected to the discharge port 3001. Through the provision of the arc-shaped material guide channel 3002, the spiral push rod 320 can more efficiently push out the dust accumulated at the bottom of the discharge box 300, and there are also slopes on both sides of the upper part of the arc-shaped material guide channel 3002 connected to the side walls of the discharge box 300, so that the dust can naturally flow into the arc-shaped material guide channel 3002.
[0023] The rotary drive assembly 400 includes a reduction gear 410 connected to the end of the screw push rod 320 at one end, a driven pulley 420 located at the other end of the reduction gear 410, a driving pulley 430 fixed to the outside of the output shaft of the drive motor 110, and a belt 440 sleeved and connected to the driving pulley 430 and the driven pulley 420. When in use, when the drive motor 110 drives the main shaft 120 and the blade 130 to rotate, it can also drive the driven pulley 420 to rotate through the driving pulley 430 and the belt 440, and reduce the speed of the output shaft of the reduction gear 410 under the speed adjustment of the reduction gear 410, thereby reducing the rotation speed of the screw push rod 320, so that the screw push rod 320 can push the dust to the discharge port 3001 at a uniform and slow speed. It is simple and reasonable. When in use, the drive motor 110 can be directly started to operate as a whole.
[0024] Furthermore, an auxiliary cover 330 is fixed on the inside of the discharge box 300 and located directly above the discharge port 3001. The auxiliary cover 330 can effectively reduce the impact of the airflow blowing from above on the discharge port 3001, so that dust can be discharged stably without being disturbed by the wind.
[0025] Furthermore, a mounting plate 500 is fixed to the outside of the fan main cabin 100 and is used to install the drive motor 110. The drive motor 110 can be positioned and installed through the mounted mounting plate 500. Of course, in actual use, a protective cover can also be provided. The protective cover is fixedly connected to the mounting plate 500, and the belt 440 and the reduction gear box 410 are covered therein to play a role of external protection.
[0026] In summary, the dust collector unloading device of this embodiment can, when in use, be sucked into the fan main cabin 100 and the discharge box 300 in sequence through the feed hopper 200. At the same time, the dust blocking inclined plates 310 staggered from top to bottom on the inside of the discharge box 300 can block the downward dust airflow layer by layer, and continuously reduce the flow rate and impact force of the wind, while also preventing dust backflow. When dust is deposited at the bottom of the discharge box 300, the starting drive motor 110 can drive the screw push rod 320 to rotate and run synchronously through the rotating drive assembly 400, and push the dust out to the outside of the discharge port 3001 at a uniform and slow speed through the screw push rod 320, effectively reducing the problem of excessive dust dispersion and secondary pollution in the unloading process.
[0027] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
