Specific embodiment 1

[0029] In order to solve the problem in the prior art that it is inconvenient to adjust the position and lift of the dust hood, it is difficult to make it as close to the material pile as possible, and smoke and dust are prone to overflow, the present embodiment adopts the following technical solutions, such as Figure 1 and Figure 4 First, the controller 8 embedded in the mounting plate 6 can be used to control the first slide rail 3 and the second slide rail 5 sequentially arranged on the receiving plate 1 to operate. Since the first slide rail 3 is slidably connected to the first slider 2 fixed on the receiving plate 1, and the second slide rail 5 is slidably connected to the second slider 4 fixed on the first slide rail 3, and the second slide rail 5 is arranged vertically and staggered with the first slide rail 3 arranged on its lower side, the receiving plate 1 can be easily moved left and right and forward and backward through the operation of the first slide rail 3 and the second slide rail 5, so as to achieve the purpose of adjusting the position of the dust collector hood so that it is located above the material pile;

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5Then, the controller 8 can be used to control the operation of the electric telescopic rod 15 fixedly installed on the lower middle side of the receiving plate 1, so that the electric telescopic rod 15 drives the connecting plate 16 fixedly connected thereto to descend. Since the connecting plate 16 is symmetrically provided with a limit sleeve 17 fixedly connected to the receiving plate 1 on the upper outer side, the inner side of the limit sleeve 17 is engaged with the movable rod 18 and cannot be disassembled. The inner middle side and the inner lower end of the movable rod 18 are respectively fixedly connected to the connecting plate 16 and the transfer plate 9. Therefore, through the operation of the electric telescopic rod 15, it is convenient to make the connecting plate 16 move along the movable rod. 18 Under the engagement limit of the limit sleeve 17, the transfer plate 9 is driven to descend. Since the support bar 10 is fixed symmetrically to the center of the outer lower part of the transfer plate 9, the inner side of the lower end of the support bar 10 is fixedly connected with the reinforcing rib 11, and the outer sides of the transfer plate 9, the support bar 10 and the reinforcing rib 11 are glued and fixedly connected with the non-woven fabric 12, it is convenient for the transfer plate 9 to drive the support bar 10, the reinforcing rib 11 and the non-woven fabric 12 to descend, so as to achieve the purpose of adjusting the height of the dust collector according to the material pile, making it as close to the material pile as possible, and effectively reducing the smoke and dust overflow during loading. Specific embodiment 2

[0032] In order to solve the problem in the prior art that it is inconvenient to control the closing of the electric butterfly valve 13 according to dust sensing, which is prone to secondary dust, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 3 During the use of the dust removal hood, the controller 8 can control the display 7 embedded in the mounting plate 6, the electric butterfly valve 13 fixedly installed on the transfer plate 9, and the dust sensor 19 embedded in the transfer plate 9 to work together, so that the dust sensor 19 can sense the dust below and the display 7 can display the data sensed by the dust sensor 19. When the dust sensor 19 senses that the dust is too high, the controller 8 controls the electric butterfly valve 13 to operate, so that the air duct 14 is connected to the transfer plate 9, so that the air duct 14 can suck and dust the dust-laden air. When the dust sensor 19 senses that the dust is at a normal value, the controller 8 controls the electric butterfly valve 13 to close, disconnect the air duct 14 from the transfer plate 9, and prevent the dust in the air duct 14 from falling, thereby reducing secondary dust.
