[0026] refer to Figure 1-Figure 5 The present embodiment provides a pneumatic scraper, comprising: an air distribution pipe head 1, a nozzle 2, a flanged bearing seat 4, a pipeline 5, a hand-held handle 6, an air control hand-held handle 7, a spring 8, and a compressed air pipe 9;

[0027] The gas distribution pipe head 1 is provided with an air inlet channel and at least two air outlet channels respectively connected to the air inlet channels, and the nozzle 2 is installed on a side of the air outlet channel away from the air inlet channel;

[0028] One end of the air distribution pipe head 1 is fixedly connected to the side of the air inlet channel away from the air outlet channel through a flanged bearing seat 4; the other end of the pipeline 5 is installed with an air control hand handle 7, a spring 8 is connected between the air control hand handle 7 and a hand handle 6, the hand handle 6 is connected to a compressed air pipe 9, and an air outlet 61 is provided in the part where the hand handle 6 is inserted into the air control hand handle 7;

[0029] The hand-held handle 6 is moved from the first position to the second position along the direction of the hand 6 approaching the air control hand handle 7 by an external force; when the hand-held handle 6 is at the first position, the air outlet 61 is in contact with the inner wall of the air control hand handle 7, and the air outlet 61 is closed; when the hand-held handle 6 is at the second position, the air outlet 61 is released from contact with the inner wall of the air control hand handle, and the air outlet 61 is opened, and at this time the spring 8 is compressed to accumulate elastic restoring force.

[0030] In this embodiment, in order to realize that the air outlet 61 can be opened or closed when the hand-held handle 6 is located at different positions, the inner wall of the air control hand-held handle 7 is divided into a first part 71 and a second part 72, and the inner diameter of the second part 72 is larger than the first part 71; when the hand-held handle 6 is located at the first position, the air outlet 61 is located at a position corresponding to the first part 71; when the hand-held handle 6 is located at the second position, at least a part of the air outlet 61 moves to a position corresponding to the second part 72. Since the inner diameter of the first part 71 is relatively small, when the air outlet 61 is located in the area where the first part 71 is located, it will be closed by the inner wall of the first part 71, thereby realizing the closing of the air outlet 61.

[0031] In addition, in this embodiment, the diameter of the nozzle 2 gradually decreases from one side connected to the air outlet channel to the other side. There are two air outlet channels, and the angle between the two air outlet channels along the horizontal direction is 180°. The angle between the air outlet channels in the vertical direction is 120°.

[0032] In order to install the spring 8 , the portion of the hand-held handle 6 exposed outside the gas control hand-held handle 7 extends radially outward to form a circle of platform 62 , and one end of the spring 8 abuts against the platform 62 to form a fixed end.

[0033] In order to fix the flanged bearing seat 4, one end of the gas distribution pipe head 1 is fixedly connected to the flanged bearing seat 4 through the flange 3. In addition, one end of the gas distribution pipe head 1 is connected to the flange 3 by welding.

[0034] In this embodiment, the air distribution pipe head 1 is connected to the nozzle 2 by threads and a sealing gasket is installed inside to ensure the compressed air diversion and the nozzle 2 changes diameter to achieve gas pressurization. When installing the nozzle 2, the two nozzles 2 are staggered at 180°. When the compressed air is ejected, the symmetry of the air pressure reaction force enables the air distribution pipe head 1 to achieve dynamic balance, and the continuous torque is the driving force for its rotation. In this embodiment, the air distribution pipe is at an angle of 120°, and the compressed air beam and the inner cavity of the material pipe can be at an obtuse angle, so as to better realize the impact and fall of the powder. The air distribution pipe head 1 is welded to the flange, and then bolted to the flanged bearing seat 4), and a metal gasket is used in the middle to ensure its sealing. The flanged bearing seat 4 is welded to the pipeline 5 to achieve overall length control and meet the depth requirements.

[0035] The hand-held handle 6 cooperates with the air-controlling hand-held handle 7, and the spring 8 plays a role of limiting and resetting. When the spring 8 is reset to stretch the hand-held handle 6 to the maximum length, the two are fitted inside, and the airflow is blocked. When the worker holds and compresses the hand-held handle 6, the airflow blocking state is released.

[0036] The hand-held handle 6 is threadedly connected to the compressed air pipe 9, and an O-shaped rubber gasket is installed inside to ensure sealing.

[0037] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
