[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0031] As shown in Figures 1-2 The present application provides a mine bag dust collector ash unloading assembly, which comprises a dust removal device 1 for filtering gas containing dust. The lower end of the dust removal device 1 is fixedly installed with a support 12, which ensures the stability of the dust removal device 1. A feed inlet 11 is arranged on one side of the upper end of the dust removal device 1, which is used to introduce the gas containing dust into the dust removal device 1. The lower end of the dust removal device 1 is fixedly installed with a collection hopper 13, which is used to temporarily store the filtered dust.

[0032] At the same time, the lower end of the collection hopper 13 is connected with an ash unloading valve 14, which is used to discharge the collected dust in the collection hopper 13. The ash unloading valve 14 is a prior art and will not be described here.

[0033] In order to unload and clean the dust temporarily stored in the collection hopper 13, an ash unloading trolley 2 is arranged below the ash unloading valve 14. The ash unloading trolley 2 has rollers 21 for movement. The upper end of the ash unloading trolley 2 is fixedly installed with a feed hopper 22, which is consistent in size with the valve port of the ash unloading valve 14.

[0034] And, the lower valve port outside of the ash unloading valve 14 is fixedly installed with a fixed plate 141, both sides of the lower end of the fixed plate 141 are fixedly installed with a support plate 142, a vertical groove 143 is vertically arranged on the support plate 142, and a horizontal groove 144 is arranged on one side of the vertical groove 143 and penetrates through one side of the support plate 142;

[0035] Meanwhile, the ash unloading trolley 2 is provided with a clamping mechanism 3, the clamping mechanism 3 is used for clamping the ash unloading trolley 2 on the support plate 142, the clamping mechanism 3 has a rotating shaft 31 rotatably connected to both sides of the ash unloading trolley 2, the height of the rotating shaft 31 is consistent with the height of the horizontal groove 144, and a support plate 32 is fixedly installed on one side of the rotating shaft 31, in the present application, the support plate 32 is L-shaped and upwardly arranged, and a horizontal rod 33 is fixedly installed between the support plates 32, so that the horizontal rod 33 can drive the support plates 32 to move the position of the ash unloading trolley 2.

[0036] The support plate 32 is further fixedly installed with a fixed shaft 34, the fixed shaft 34 is arranged on one side of the rotating shaft 31, and the upper end of the feeding hopper 22 is fixedly installed with a rubber sheet 23.

[0037] Therefore, when it is necessary to unload and clean the dust temporarily stored in the collecting hopper 13, the operator pushes the ash unloading trolley 2 to the lower side of the ash unloading valve 14, and makes the rotating shaft 31 and the fixed shaft 34 enter the horizontal groove 144, until the rotating shaft 31 reaches the vertical groove 143, at this time, the operator presses the horizontal rod 33 downward, rotates the support plate 32 downward along the rotating shaft 31, and moves the fixed shaft 34 in the horizontal groove 144 to the vertical groove 143, until it reaches the vertical groove 143, because the support plate 32 rotates downward, the rotating shaft 31 slides upward along the vertical groove 143, so that the ash unloading trolley 2 as a whole moves upward, the feeding hopper 22 is attached to the ash unloading valve 14 (as shown in detail in Figure 4 ), and the rubber sheet 23 is pressed to ensure its connection and sealing, then the ash unloading valve 14 is opened, and the dust in the collecting hopper 13 enters the ash unloading trolley 2 under the action of gravity;

[0038] After the ash is unloaded, the horizontal rod 33 is rotated upward to rotate the support plate 32 upward, and the fixed shaft 34 moves outward along the horizontal groove 144, until the rotating shaft 31 falls to the bottom of the vertical groove 143, then the ash unloading trolley 2 can be pulled out.

[0039] In order to prevent the dust from entering the ash unloading trolley 2 and flying outward, as shown in Figure 3 , one side of the feeding hopper 22 is provided with a matching groove 24, and a baffle 25 is slidably connected in the matching groove 24, so that when the baffle 25 is located in the matching groove 24, the feeding hopper 22 is completely closed, and one side of the baffle 25 is provided with a handle 26.

[0040] Therefore, before the ash is unloaded, the operator pulls out the baffle 25 through the handle 26, and after the ash is unloaded, the ash unloading valve 14 is first closed, and then the baffle 25 is inserted into the matching groove 24, so as to prevent the dust in the ash unloading trolley 2 from floating outward, thereby preventing part of the dust from floating during the ash unloading process, avoiding secondary dust raising, improving the working environment, preventing the floating dust from overflowing to the operation area, and ensuring the operation safety.

[0041] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
