[0040] In some embodiments, the first sealing mechanism comprises sealing plates a 9 and b 10 arranged opposite to each other, and the second sealing mechanism comprises soft curtains a 6 arranged opposite to each other, and the soft curtains a 6 are connected with the cover 1.

[0041] In some embodiments, the sealing plate b 10 comprises a soft curtain b 11 or a metal roller shutter 5 arranged at the bottom, and the soft curtain b 11 or the metal roller shutter 5 is connected with the sealing plate b 10. Due to the limitation of the arrangement of other operation facilities on the site, the sealing plate b 10 adopts a semi-sealing mode to avoid interference with the arrangement of other operation facilities on the site. Therefore, the soft curtain a 6 and / or the metal roller shutter 5 are also used to seal the lower half part, so that the sealing effect is realized and the above problems are avoided.

[0042] In the application, the soft curtains a 6 and b 11 are made of high-temperature-resistant cloth material, as shown in Figures 14-16 The soft curtain b 11 is in the shape of a strip, the upper end of the soft curtain b 11 is embedded in the cover 1, and the lower end of the soft curtain b 11 is flush with the bottom of the sealing plates a 9 and b 10.

[0043] In some embodiments, the second sealing mechanism further comprises a metal roller shutter 5 arranged outside the soft curtain a 6.

[0044] The present application adopts a design method of flexible double-layer segmentation in combination, which fills the process path of the collector which cannot be fully closed due to the limitation of the site during the operation process. The metal roller shutter 5 is rolled up when the collector is running, and the soft curtain a6 can be moved to the working position with the mobile collector and is not affected by the obstacles. When the non-mobile working machine 14 is working at the end of the collector, the part is naturally blocked by the soft curtain a6, and the metal roller shutter 5 can be adjusted to the appropriate height position, and the non-working end metal roller shutter 5 can be adjusted to the ground level position to close the collector. At this time, the collector is not damaged due to the swing of the mechanical hook 16 driven by the mechanical arm 15 of the non-mobile working machine 14, and the integrated operation design mode of working, collecting and closing can be effectively achieved. The metal roller shutter 5 adopts a micro-magnetic high-temperature-resistant stainless steel single plate, and the two sides are designed to be extended and overlapped. In addition, the micro-magnetic effect makes the closure more airtight, and the dust and waste are not easy to invade and are easy to clean.

[0046] The roller shutter power element 24 adopts an electric positioning function, is fixed to the outside of the soft curtain a6, and adjusts the up-down use position of the metal roller shutter 5 at any time according to the equipment condition of the non-mobile working machine 14 and the use demand, so that the soft curtain a6 can run at any time with the mobile collector, thereby achieving good running and effective closing. The roller shutter power element 24 adopted by the present application is a motor with an electromagnetic brake. When the motor is started, the brake is released. When the motor is closed, the brake plate is closed, so that the metal roller shutter 5 can be opened and rolled up at will to control the height position.
