The baffle plate 6 is located at the upper end of the ash outlet 5, and the lower end of the ash outlet 5 is exposed for ash output. At this time, the slider 7 is located at the upper end of the outer frame 17, that is, the lever 21 is located at point C in the groove 20, and then the device is started , the lead screw 3 actively rotates to drive the ash hopper 2 to rise. During the rising process of the ash hopper 2, the ash in the ash hopper 2 is wiped on the wall from the ash outlet 5 under the action of the pump. At the same time, the nut 13 and the wire The lever 3 meshes and rotates synchronously, drives the input shaft 12 of the gearbox 9 to rotate, the output shaft 10 drives the push plate 11 to rotate slowly, pushes the wedge-shaped block 8 to move slowly, pushes the slider 7 to move upward in the outer frame 17, and the lever 21 is in the groove. Move from point C to point D within 20, when moving to point D, push plate 11 just pushes wedge-shaped block 8 to the limit position, push plate 11 will not affect the movement of wedge-shaped block 8, spring 18 will slide block 7 to Push down, so that the wedge-shaped block 8 returns to the original position, the lever 21 moves from point D to point A, and the baffle plate 6 moves to the lower end of the ash outlet 5, exposing the upper end position for ash output, according to the height of the wall. Adjust the transmission ratio of the gearbox 9 so that in one plastering process, the position of the slider 7 is only changed once, so that in one plastering process, the ash output position is at the bottom when it is at the bottom, and the ash output position is at the bottom when it reaches the top. The ash position is located at the top, so that the ground position and the ceiling position can also be plastered. During the position change of the slider 7, due to the existence of the gearbox 9, the output shaft 10 rotates slowly, and the push plate 11 pushes the wedge block 8 to move. The speed of the slider 7 is relatively slow, and the speed of the position switching of the slider 7 is relatively slow, that is, the position change of the ash outlet 5 blocked by the baffle 6 is in a slow process, and during this process, the baffle 6 will move to the position of the ash outlet 5. The middle part, so that the upper and lower parts of the ash outlet 5 are exposed, so that the ash will be discharged from the upper and lower parts of the ash outlet 5 at the same time, so that when the position of the baffle plate 6 is switched, there will be no ash output from the lower part of the ash outlet 5. Immediately switch to the upper part to avoid the dislocation of the plaster on the wall, so that one plaster can be plastered from the ground to the ceiling.

In order to realize the conversion of the position of the baffle plate 6, a control mechanism is provided on the connecting plate 4, and the control mechanism includes a slide block 7, an outer frame 17, a wedge block 8, a gearbox 9, a push plate 11, a nut 13, and the nut 13 and the lead screw 3 meshing provides power for the control mechanism, the gearbox 9 converts the power received by the nut 13, and outputs the required power to the push plate 11, the push plate 11 pushes the wedge block 8 to move, and the wedge-shaped surface of the wedge block 8 pushes the slider 7 slides in the outer frame 17, thereby realizing the change of the position of the baffle plate 6 at the ash outlet 5.

In order to ensure the stability of the position of the slider 7 in the outer frame 17, a groove 20 is opened on the slider 7, and the groove 20 is divided into four sections: AB section, BC section, CD section and DA section. The driving rod 21 in the groove 20, after the driving rod 21 is fixed in the groove 20, the position of the slider 7 is fixed in the outer frame 17, because the top of the slider 7 is provided with a spring 18 connected with the outer frame 17, the groove Points A and C on 20 are the rest positions of the lever 21.

In order to ensure that the lever 21 can move in one direction along the direction of point A→point B→point C→point D, point A, point B, point C and point D are all provided with non-return steps 22, so that the lever 21 moves from After point A arrives at point B, the non-return step 22 makes the lever 21 move only to point C and cannot reversely return to point A. Similarly, when the lever 21 receives an upward thrust at point C, it will move toward point D. Moving instead of point B, the lever 21 can only move to point A when it is at point D, and it can only move to point B when it is at point A, so that it can ensure that the slider 7 will inevitably produce a relatively large position during a position change process. The large displacement realizes the transformation from point A to point C, that is, the position of the baffle plate 6 at the ash outlet 5 can be changed from being located at the upper end to being located at the lower end, so that when the ash hopper 2 reaches the top, the ash on the ash outlet 5 The position is changed, instead of returning to the state of ash coming out of the lower end, thus ensuring the integrity of the plastering.

In order to facilitate the change of the position of the baffle plate 6, a chute 16 is provided in the ash hopper 2 on both sides of the ash outlet 5, and the height of the chute 16 is higher than that of the ash outlet 5, and the baffle plate 6 is in the chute 16. Sliding, because the baffle 6 is fixedly connected to the slider 7, and the slider 7 needs to pass through the point B in the process from point A to point C, and the displacement of the slider 7 between point A and point B is greater than that of point A To the displacement between point C, so the upper and lower ends of the chute 16 should have a buffer position for the movement of the baffle plate 6, so as to prevent the baffle plate 6 from being unable to switch positions.

In order to facilitate the up and down movement of the ash bucket 2, a plurality of sliding rods 14 are arranged on the bottom plate 1, and a sleeve is provided on the ash bucket 2. When the ash bucket 2 moves up and down under the action of the lead screw 3, the sliding rods 14 and the sleeve The cooperation provides a stable sliding track for the ash hopper 2, so that the distance between the ash hopper 2 and the wall remains stable, thereby ensuring the thickness of the plastering layer.

There is a one-way transmission between the nut 13 and the input shaft 12 of the gearbox 9. The nut 13 is engaged with the lead screw 3 and rotates all the time. During the process, the nut 13 cannot drive the input shaft 12 to rotate, and the position of the baffle plate 6 at the ash outlet 5 is manually adjusted, and the slide block 7 is pushed to change the position of the driving rod 21 in the groove 20, thereby changing the position of the baffle plate 6.

Compared with the prior art, the present invention has the following beneficial effects: 1) In one plastering process, the entire plastering from the ground to the ceiling is realized without leaving any blanks, and there is no need for post-filling plastering, which reduces the workload , can shorten a certain construction time; 2) In the process of switching the ash outlet position, the position of the baffle plate 6 is switched slowly, so that the ash outlet position is not a jumpy switch, so that the wall surface in the switching process section Plastering can still be achieved, without the need for post-filling, avoiding other adverse effects while achieving plastering on the floor and ceiling; 3) Switching of the ash outlet position does not affect the relationship between the ash hopper 2 and the ash outlet 5 and the wall The distance and angle between the surfaces keeps the thickness of the plastering layer stable, avoiding the occurrence of changes in the thickness of the plastering layer affecting the flatness of the wall and requiring later renovations.
