Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 - Figure 5 , the present invention provides a technical solution, which specifically includes the following embodiments:

[0027] Embodiment 1:

[0028] A welded assembly of a shot blasting machine housing includes a shot blasting machine housing 1. The shot blasting machine housing 1 is provided with a box door 11, and the box door 11 is flush with the ground. A collection bin 7 is installed at the bottom of the box door 11. The collection bin 7 can be installed below the ground, and a screw conveyor is arranged inside it for conveying the falling shot material. The collection bin 7 is communicated with the elevator 4, and the elevator 4 is communicated with the separator 5. The elevator 4 conveys the shot material to the separator 5 for shot material recovery. The shot blasting machine housing 1 is also fixed to the dust collector 6, and the dust collector 6 filters the smoke and dust during the shot blasting process. A shot blasting device 8 is also installed on the shot blasting machine housing 1, which is used for throwing the shot material.

[0029] A hoisting component 2 is installed at the top of the shot blasting machine housing 1. The hoisting component 2 includes a hook 21 and a support component 20. The hook 21 enters the shot blasting machine housing 1 along the long slot 22. The long slot 22 is opened at the top of the shot blasting machine housing 1 and is aligned with the center of the top of the box door 11. It is used for the hook 21 to carry the workpiece into the interior of the shot blasting machine housing 1, put down the workpiece and then return for shot blasting. When shot blasting, dust will be generated. The long slot 22 is blocked or opened by the automatic sealing mechanism 3 to prevent the dust from overflowing and spreading. The support component 20 supports the smooth movement of the hook 21. The automatic sealing mechanism 3 is fixed on the surface of the long slot 22. The automatic sealing mechanism 3 includes a motor 30. The motor 30 is fixedly connected to the top of the shot blasting machine housing 1. The output shaft of the motor 30 is fixedly connected to a lead screw 32. The helix angle of the lead screw 32 is relatively large, which is 40 degrees. The lead screw 32 is threadedly connected to a nut 33. The nut 33 is fixedly connected to a baffle 34. The baffle 34 is arranged above the long slot 22. The lead screw 32 is connected to a support rod 35 by bearings. The support rod 35 is fixedly connected to a support frame 31. The support frame 31 is fixedly connected to the shot blasting machine housing 1.

[0030] In the utility model, the motor 30 drives the lead screw 32 to rotate through the automatic sealing mechanism 3, drives the nut 33 to move along the lead screw 32, so that the baffle 34 can move. When the hook 21 hoists the workpiece into the shot blasting machine housing 1, the baffle 34 moves away from the long slot 22, and the long slot 22 is in an open state. When the hook 21 leaves the shot blasting machine housing 1, the baffle 34 blocks the long slot 22 and seals the long slot 22, isolating the dust and debris generated during shot blasting in the shot blasting machine housing 1 and preventing them from leaking out, thereby improving the environmental protection effect and ensuring the health of the staff.

[0031] The support component 20 includes a guide rail 29. The middle of the guide rail 29 is fixedly connected to an n-shaped frame 23. The n-shaped frame 23 is fixedly connected to the shot blasting machine housing 1. First reinforcing rods 24 and second reinforcing rods 26 are fixed on both sides of the n-shaped frame 23. The first reinforcing rods 24 and the second reinforcing rods 26 are respectively fixedly connected to a cross bar 25. The cross bar 25 is fixedly connected to the guide rail 29. An electric hoist 28 is installed on the guide rail 29. The hook 21 is installed on the electric hoist 28;

[0032] A third reinforcing rod 27 is also fixed on the guide rail 29. The third reinforcing rod 27 is fixedly connected to the shot blasting machine housing 1. The reinforcing support structures composed of two groups of the first reinforcing rods 24, the second reinforcing rods 26 and the cross bar 25 are symmetrically arranged with respect to the n-shaped frame 23.

[0033] The present invention fixes the guide rail 29 stably on the shot blasting machine housing 1 by arranging the support assembly 20. The first reinforcing rod 24 and the second reinforcing rod 26 can provide stronger support for the guide rail 29, making it not easy to bend. Thus, the length of the guide rail 29 that can be set is increased, and the hoisting range of the hoisted workpiece is expanded.

[0034] As a further explanation of this embodiment, two first rubber sheets 301 are fixed on the baffle 34. The first rubber sheets 301 are respectively arranged on the front and rear sides of the long strip hole 22. One end of a second rubber sheet 302 and a third rubber sheet 303 is fixed to the bottom surface of the baffle 34. The other ends of the second rubber sheet 302 and the third rubber sheet 303 are respectively located on both sides of the long strip hole 22 in the length direction.

[0035] The first rubber sheet 301 is arranged on the baffle 34 to block the joint gaps between the front and rear ends of the long strip hole 22 and the baffle 22. The second rubber sheet 302 and the third rubber sheet 303 are arranged to cover the gaps between the baffle 34 and the left and right sides of the long strip hole 22, enhancing the sealing performance. Among them, the first rubber sheet 301, the second rubber sheet 302, and the third rubber sheet 303 naturally sag and fit with the baffle 34 by their own weights, and the lengths of the first rubber sheet 301, the second rubber sheet 302, and the third rubber sheet 303 are greater than the distances from them to the baffle 34.
