[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Example 1
[0022] See also Figs. 1 to 4 The hopper 2 is provided with a guide plate 5 and a movable plate 6, and the guide plate 5 is provided with a guide plate 6. The guide plate 5 is provided with a guide plate 6 and a movable plate 6. The guide plate 5 and the guide block 3 are provided with support balls. The number of support balls is greater than 100. The setting of the support balls can ensure that the bottom surface of the guide plate 5 is parallel to the ground, and the top surface of the guide plate 5 and the movable plate 6 can complete the guidance of the position of the gravel.
[0023] The sand box 2 is supported above with a feed port 4, and the bottom end of the sand box 2 is provided with a feed port connected to the inner cavity of the gun body 1 near the front end. The setting of the feed port 4 can feed materials into the inner cavity of the sand box 2, and the setting of the feed port can continuously spray sand and gravel outward.
[0024] The inner side of the guide plate 5 and the bottom surface of the movable plate 6 are respectively fixedly connected with support plates 8, and a support spring 10 is connected between the two support plates 8. A limit block 9 is fixedly installed behind the front support plate 8. The cooperation of the guide plate 5 and the movable plate 6 can ensure the fit between the rear side of the guide block 3 and the rear side of the sand box 2, thereby separating the space between the gravel and the support balls.
[0025] The bottom surface of the movable plate 6 fits into the top surface of the guide plate 5, and the top surfaces of the movable plate 6 and the guide plate 5 are inclined with the back higher and the front lower. The rear side of the movable plate 6 fits into the inner wall of the sand box 2. The inclined setting of the guide plate 5 and the movable plate 6 can continuously guide the sand and gravel to the guide block 3, thereby completing the unloading.
[0026] The guide block 3 is located outside the feed port, the outer height of the guide block 3 is greater than the inner height, and the height of the front end of the guide plate 5 and the outer side of the guide block 3 are located in the same horizontal plane.
[0027] The limit block 9 extends forward to the front end of the front support plate 8, and the bottom surface of the guide plate 5 and the bottom surface of the sand box 2 are parallel to the limit block 9. The setting of the limit block 9, the support plate 8 and the support spring 10 can limit the range of movement of the movable plate 6, so that the movable plate 6 will fit into the top surface of the guide plate 5 during the movement process.
[0028] In summary, the pneumatic sand blasting gun, in use, first fills the sand box 2 with sand through the upper part of the sand box 2 to the inner cavity of the sand box 2, then the sand is accumulated on the upper surface of the flow guide block 3 and the flow guide plate 5 and the movable plate 6, and the sand is guided to the flow guide block 3 under the slope of the flow guide plate 5 and the movable plate 6, in the sand blasting process, the sand is continuously guided downward under the guidance of the flow guide block 3, then the sand is continuously sprayed out through the gun body 1, in the sand blasting process, the amount of sand in the gun body 1 is gradually reduced, when the gun body 1 is tilted backward, the support balls at the bottom of the flow guide block 3 and the flow guide plate 5 are also accumulated backward, thereby pushing the flow guide plate 5 to rotate around the axis of the support shaft 7, in the rotation process of the flow guide plate 5, the flow guide plate 5 is supported outwardly by the support plate 8 and the support spring 10 to move the movable plate 6, thereby the outer side of the movable plate 6 is attached to the rear of the sand box 2, so that the top surface of the flow guide plate 5 is always in an inclined state.
