DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Reference Figures 1-3The utility model provides an embodiment: a kind of pneumatic dust conveying pipe bottom disturbance device, including pipeline 1 and splicing component, splicing component is arranged in the inside of pipeline 1, the bottom of pipeline 1 is fixedly connected with base 2, provides stable support for entire device. The bottom of base 2 is provided with sealing plate 3, when needing to maintain or replace component inside device, can open sealing plate 3 and operate. The top of pipeline 1 is fixedly connected with mounting box 4, and mounting box 4 provides installation space for inside rotating rod 5 etc. component. Two rotating rods 5 are rotatably connected in the inside of mounting box 4, and the rotation of rotating rod 5 is the key of the operation of entire device. The one end of left rotating rod 5 penetrates the inner wall of pipeline 1 and is fixedly connected with impeller 6, when the inside of pipeline 1 starts to send air from left side, powerful airflow can blow impeller 6 and rotate fast. The inside of pipeline 1 is provided with disturbance component, and disturbance component is used to sweep dust inside pipeline 1, to ensure that pipeline 1 is unobstructed. Disturbance component includes turntable 8, and the top of turntable 8 is fixedly connected in the one end of lower rotating rod 5. When left rotating rod 5 rotates, under the cooperation of two bevel gears 7, so that lower rotating rod 5 drives turntable 8 to rotate. The bottom of turntable 8 is fixedly connected with limiting frame 9, and the inner wall of pipeline 1 is fixedly connected with two movable columns 10, and the inner side of two movable columns 10 is slidably connected with sliding frame 11. Sliding frame 11 can stably slide along specific path under the joint action of limiting frame 9 and movable column 10. The outer side of sliding frame 11 is fixedly connected with two connecting rods 12, and the bottom of connecting rod 12 is provided with combination block 13, and the bottom of combination block 13 is fixedly connected with straight strip plate 14, and the bottom of straight strip plate 14 is fixedly connected with multiple arc-shaped brush plates 15. The outer side of movable column 10 is slidably connected with the inner side of sliding frame 11, to ensure the smoothness of sliding. The bottom of arc-shaped brush plate 15 is attached to the inner wall of pipeline 1, can effectively sweep dust in the inner wall of pipeline 1. The other end of two rotating rods 5 is fixedly connected with bevel gear 7, and two bevel gears 7 are engaged, realize the transmission of power.

[0025] Specifically, when the inside of the pipeline 1 is blown from the left side, a strong airflow rapidly flows in, at this time, the airflow can blow the impeller 6 to rotate. The rotation of the impeller 6 further drives the left rotating rod 5 to start rotating. Under the close and accurate cooperation of the two bevel gears 7, the lower rotating rod 5 obtains power and drives the rotating disc 8 to rotate. With the rotation of the rotating disc 8, the movable column 10 plays an important guiding role, which can drive the sliding frame 11 to slide smoothly and regularly along the inside path of the limiting frame 9. In this process, the movement of the sliding frame 11 will further drive the connecting rod 12 to move, and the connecting rod 12 will drive the combined block 13 to move. With the movement of the combined block 13, a plurality of arc-shaped brush plates 15 connected thereto begin to move back and forth. These arc-shaped brush plates 15 can closely fit the inner wall of the pipeline 1 during reciprocating movement, effectively sweeping the dust accumulated on the inner wall of the pipeline 1. At the same time, the wind entering the inside of the pipeline 1 continues to flow, which can blow away the dust swept by the arc-shaped brush plates 15, thereby keeping the pipeline 1 clean and ensuring the smooth operation of the pneumatic dust conveying.

[0026] Referring to Figures 2-4 The splicing assembly includes a plug rod 20 which is slidingly connected at the inner through hole of the connecting rod 12, and serves to connect the connecting rod 12 and the combined block 13. The inner wall of the combined block 13 is fixedly connected with a spring 16 which has elasticity and can be stretched and contracted within a certain range. One end of the spring 16 is fixedly connected with a clamping block 17, and the inside of the combined block 13 is provided with a ball 18, the outside of which is in contact with the outside of the plug rod 20, and the outside of the clamping block 17 is in contact with the outside of the plug rod 20, thereby ensuring the stable connection of the plug rod 20 inside the combined block 13. The outside of the connecting rod 12 is threadedly connected with a limiting column 19, the inside of the plug rod 20 is provided with a clamping groove 21, and the outside of the plug rod 20 is slidingly connected with the inner through hole of the combined block 13, one end of the limiting column 19 is clamped in the inside of the clamping groove 21, thereby further enhancing the stability of the connection.

[0027] Specifically, when the arc-shaped brush plates 15 need to be replaced due to wear, the sealing plate 3 can be opened, and then the limiting column 19 is rotated, and one end of the limiting column 19 is gradually pulled out from the inside of the clamping groove 21. Then, the plug rod 20 is carefully pulled out from the inside of the combined block 13 and the connecting rod 12. Through such an operation, the connection between the connecting rod 12 and the combined block 13 is released. At this time, the combined block 13 together with the plurality of arc-shaped brush plates 15 can be removed. This disassembly and replacement method is very convenient, without the need for complex tools or complicated operation procedures. Even in a relatively narrow space or in an emergency, the replacement of the arc-shaped brush plates 15 can be quickly completed, greatly improving the maintenance efficiency and the stability of the operation of the equipment.

[0028] Working principle: when the inside of pipeline 1 starts to send air from left side, can blow impeller 6 to rotate, and then drive left side rotating rod 5 to rotate, under the cooperation of two bevel gears 7, make the lower rotating rod 5 drive rotating disc 8 to rotate, so that movable column 10 can drive sliding frame 11 to slide along the inside path of limiting frame 9, and then make connecting rod 12 drive combination block 13 to move, so that multiple arc-shaped brush plates 15 move back and forth, sweep the dust on the inner wall of pipeline 1, and the wind entering the inside of pipeline 1 blows away the dust, in addition, can open sealing plate 3 to replace the worn arc-shaped brush plate 15, after rotating limiting column 19, pull out the one end of limiting column 19 from the inside of clamping groove 21, then pull out plug rod 20 from the inside of combination block 13 and connecting rod 12, so that the connection between connecting rod 12 and combination block 13 is lost, can take down combination block 13 together with multiple arc-shaped brush plates 15, this dismounting and replacing mode is more convenient.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
