DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] Please refer to Figures 1-4 The present application provides a technical solution: a dust removal device for powder loading, comprising an equipment frame 1, a dust suction cover 3, and a universal hose 4 connected to the dust suction cover 3. The inner side of the equipment frame 1 is slidingly connected with a cross frame 5. A telescopic connecting piece is arranged between the cross frame 5 and the dust suction cover 3. Two sliding arms 16 are slidingly embedded in the cross frame 5. A rotary arm 8 is rotatably connected in the cross frame 5. A transmission mechanism is arranged in the cross frame 5. When the rotary arm 8 rotates, the two sliding arms 16 move synchronously under the action of the transmission mechanism. The outer side of the cross frame 5 is provided with a clamping structure to limit the random rotation of the rotary arm 8.
[0024] Directly contact with the dust source for collecting dust. The universal hose 4 is connected to the dust suction cover 3, which can transport the collected dust to the industrial dust collector arranged outside the equipment frame 1. The universal hose 4 provides flexible connection, allowing the dust suction cover 3 to move within a certain range without restriction, facilitating alignment and following the dust source.
[0025] By adjusting the height position of the cross frame 5 relative to the equipment frame 1, the dust suction cover 3 adjusts the height synchronously with the cross frame 5 under the action of the telescopic connecting piece. The telescopic connecting piece is arranged between the cross frame 5 and the dust suction cover 3, allowing the dust suction cover 3 to adjust the distance from the dust source as needed.
[0026] After adjusting the height position of the cross frame 5, rotate the rotary arm 8 to make the two sliding arms 16 move synchronously in the opposite direction under the action of the transmission member until the end of the sliding arm 16 tightly abuts the inner wall of the equipment frame 1, completing the fixation of the vertical height of the cross frame 5, thereby ensuring that the cross frame 5 can be fixed at the vertical height when the dust suction cover 3 is removing the dust generated by loading, ensuring the stability of the dust suction cover 3 when removing dust.
[0027] Specifically, as Figures 2-4As shown, the telescopic connecting piece comprises a slide rod 7 rotatably connected inside the cross frame 5, and a slide sleeve 6 slidably sleeved outside the slide rod 7, and fixed with the dust cover 3.
[0028] The slide rod 7 is rotatably connected inside the cross frame 5, and the slide sleeve 6 is slidably sleeved outside the slide rod 7 and fixed with the dust cover 3. This design enables the dust cover 3 to be flexibly moved in the horizontal direction after adjusting the vertical height of the cross frame 5, and to adjust the distance from the dust source.
[0029] Specifically, as shown in Figure 4 The end of the slide arm 16 outside the cross frame 5 is fixed with an abutting plate 18, and the side wall of the equipment frame 1 is formed with a rubber pad 2 abutting the abutting plate 18.
[0030] The outer wall of the abutting plate 18 is formed with teeth, which are used to improve the erection stability of the cross frame 5 by being pressed and engaged with the rubber pad 2 after the slide arm 16 is extended out of the cross frame 5.
[0031] Specifically, as shown in Figure 2 and Figure 4 The transmission mechanism comprises a rotating shaft 14 rotatably connected in the cross frame 5 and coaxially fixed with the rotating arm 8, the side wall of the rotating shaft 14 is formed with a protrusion 15, and the slide arm 16 is slidably sleeved outside the rotating shaft 14, and the inner wall of the slide arm 16 is formed with a slide rail 17 slidably matched with the protrusion 15.
[0032] When the rotating shaft 14 rotates with the rotating arm 8, the protrusion 15 fixed on the rotating arm 8 will slide along the slide rail 17, and the slide arm 16 will be driven to slide along the cross frame 5 through the compression transmission of the side wall of the protrusion 15 to the inner wall of the slide rail 17.
[0033] The clamping structure comprises a sliding block 11 slidably connected in the rotating arm 8, the side wall of the sliding block 11 is fixed with a supporting rod 13, the rotating arm 8 is formed with a sliding groove 801 slidably matched with the supporting rod 13, and the outer end of the cross frame 5 is fixed with a limiting block 9, and the limiting block 9 is formed with a notch slidably matched with the supporting rod 13.
[0034] After adjusting the vertical height of the cross frame 5, the rotating arm 8 is rotated to align the supporting rod 13 fixed with the sliding block 11 with the notch of the limiting block 9, and when the sliding block 11 slides towards the rotating arm 8, the supporting rod 13 will be embedded in the notch of the limiting block 9, thereby limiting the arbitrary rotation of the rotating arm 8 and keeping the two slide arms 16 in a stable extended state.
[0035] The magnetic attraction block 10 is fixed in the rotary arm 8 and is matched with the sliding block 11, and the handle 12 is rotatably connected to the sliding block 11. Through the handle 12, the user can conveniently operate. When the rotary arm 8 is in the vertical state, the user can adjust the height of the horizontal frame 5 by pulling the handle 12. When the rotary arm 8 is in the horizontal state, the sliding block 11 will be attracted to the rotary arm 8 by the magnetic attraction of the magnetic attraction block 10, so that the supporting rod 13 fixed on the side wall of the sliding block 11 is embedded in the notch of the limiting block 9. The sliding block 11 is made of iron-containing metal material.
[0036] The above description of the embodiments enables those skilled in the art to make or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
