DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Figure 1-5 As shown: it includes a top cover 1 of a suspended shot blasting machine, a notch 11 is provided on the top surface of the top cover 1, a hook 2 is installed inside the notch 11, a sealing device 3 is provided on the top surface of the top cover 1, the sealing device 3 includes a U-shaped plate 31 fixedly installed on the top surface of the top cover 1, the U-shaped plate 31 is located directly above the notch 11, a first slide groove 32 is penetrated on the rear side of the sealing device 3, and a second slide groove 33 is penetrated on the left and right sides of the sealing device 3, a first baffle 34 and a second baffle 38 are respectively slidably mounted inside the first slide groove 32 and the second slide groove 33, and a first clearance groove 35 and a second clearance groove 39 are respectively penetrated at the ends of the first baffle 34 and the second baffle 38 that contact the hook 2, the width of the first baffle 34 and the second baffle 38 are the same as the width of the U-shaped plate 31, and the first clearance groove 35 and the second baffle 38 are respectively penetrated. The groove 35 is semicircular, and the second clearance groove 39 is a quarter circle. The first clearance groove 35 and the second clearance groove 39 are both fitted with the arc surface of the hook 2. By clamping the hook 2 inside the first clearance groove 35 and the second clearance groove 39, the purpose of making the hook 2 completely fit with the first clearance groove 35 and the second clearance groove 39 is achieved, avoiding the situation where there is a gap between the hook 2 and the first baffle plate 34 and the second baffle plate 38. Then, the notch 11 is sealed by the first baffle plate 34 and the second baffle plate 38 to avoid the steel shot inside the hanging shot blasting machine from splashing out through the notch 11. This solves the problem that after the hook is inserted between the rubber plates in the existing device, the rubber plate cannot be completely fitted with the surface of the hook, and the steel shot may still splash out from the gap between the rubber plate and the hook;

[0025] Example 2: Figure 1-4As shown: a limiting plate 36 is fixedly installed on one end of the first baffle 34 away from the hook 2, one end of the first spring 37 is fixedly installed on the side wall of the limiting plate 36, and the other end of the first spring 37 is fixedly installed on the side wall of the U-shaped plate 31; a limiting plate 310 is fixedly installed on the side of the second baffle 38 away from the hook 2, one end of the second spring 311 is fixedly installed on the side wall of the limiting plate 310, and the other end of the second spring 311 is fixedly installed on the side wall of the U-shaped plate 31; a guide plate 312 is fixedly installed on one end of the second baffle 38 away from the second make way groove 39, and the guide plate 312 is integrally formed with the second baffle 38, and the limiting plate 36 and the first spring 37 are fixedly installed on the side wall of the U-shaped plate 31. The setting of the spring 37 can limit the first baffle 34, and the second baffle 38 can be limited by the limiting plate 310 and the second spring 311. When the hook 2 moves inside the slot 11, the guide plate 312 can guide the hook 2 to move the hook 2 toward the inside of the slot 11, and then push the second baffle 38 to both sides. When the hook 2 is clamped in the second yielding groove 39, the second baffles 38 on both sides are fitted together under the action of the elastic force of the second spring 311, thereby avoiding the first baffle 34 and the second baffle 38 from moving randomly and improving the sealing effect of the first baffle 34 and the second baffle 38.

[0026] Working principle and use process of the utility model: When the top sealing device of the hanging shot blasting machine is used, the hook 2 is moved toward the inside of the slot 11, and the guide plate 312 and the second baffle 38 are pushed toward both sides by the hook 2. At this time, the second spring 311 is compressed. When the hook 2 moves to the inside of the second make way groove 39 and the first make way groove 35, the compressed second spring 311 resets the second baffles 38 on both sides, and then the second baffles 38 on both sides fit together. At this time, the hook 2 is located inside the first make way groove 35 and the second make way groove 39. The slot 11 can be sealed by the second baffle 38 and the first baffle 34 to prevent the steel shots inside the hanging shot blasting machine from splashing out through the slot 11.
