[0027] 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.

[0028] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0029] Embodiment 1: In order to solve the problem that the contact time between the object and the bristles in the prior art is relatively short, it is difficult to clean the dust on the surface of the casting only by using the bristles, so the following technical solution is disclosed, see Figure 1-Figure 4 As shown, the separation mechanism is arranged on the bracket 1, and the separation mechanism is operated through the transmission mechanism, thereby fully separating the steel sand adhered to the casting.

[0030] The transmission mechanism includes a chain assembly 4, which is installed on the front side of the lower conveying roller 3 and the upper conveying roller 5, and a conveyor belt 11 is installed between the upper conveying roller 5 on the far right and the lower conveying roller 3 on the far left, and an upper bevel gear assembly 10 and a lower bevel gear assembly 13 are installed on the front sides of the upper and lower shafts of the conveyor belt 11, respectively, and a middle bevel gear assembly 16 is installed between the front side of the leftmost lower conveying roller 3 and the bracket 1; an electric telescopic rod 7 is installed on the mounting frame, and a connecting rod 9 is installed on the output end of the electric telescopic rod 7, and a brush assembly 8 is rotatably connected to the connecting rod 9.

[0031] The separation mechanism includes a fixed column 14 and a fixed rod 15 inserted into the fixed column 14, the fixed column 14 is installed on the shafts of the lower bevel gear assembly 13 and the middle bevel gear assembly 16, and the fixed rod 15 is a prismatic structure, and the fixed rod 15 is installed on the shafts of the middle bevel gear assembly 16 and the upper bevel gear assembly 10; a cam 12 is fixedly passed through the rear side of the lower bevel gear assembly 13, a fixed plate 17 is installed below the mounting frame, and the shortest vertical distance from the fixed plate 17 to the shaft of the lower bevel gear assembly 13 is less than the longest distance from the shaft of the cam 12 to the outside.

[0032] The motor on the rear side of the bracket 1 drives the upper chain assembly 4 to run, and the rotation of the chain assembly 4 causes the multiple upper conveying rollers 5 to rotate synchronously, and the conveyor belt 11 causes the lower bevel gear assembly 13 to rotate, and the lower bevel gear assembly 13 causes the lower fixed column 14 to rotate, and the rotation of the lower fixed column 14 drives the lower fixed rod 15 to rotate synchronously, and the rotation of the lower fixed rod 15 drives the middle bevel gear assembly 16 to rotate synchronously, and the rotation of the middle bevel gear assembly 16 causes the upper fixed column 14 to rotate synchronously, and the rotation of the upper fixed column 14 drives the upper fixed rod 15 to rotate synchronously, thereby causing the chain assembly 4 to rotate, and the rotation of the chain assembly 4 causes the lower conveying roller 3 to rotate synchronously, and the lower bevel gear assembly 13 The rotation causes the cam 12 to rotate synchronously. When the cam 12 rotates to contact with the fixed plate 17, the cam 12 pushes the fixed plate 17, thereby causing the fixed plate 17 to move upward. During the upward movement of the fixed plate 17, the lower conveying roller 3, the middle bevel gear assembly 16, the lower fixed rod 15 and the upper fixed column 14 are driven to move upward synchronously. When the cam 12 rotates to no longer contact with the fixed plate 17, the fixed plate 17, the mounting frame and the lower conveying roller 3 move downward due to their own weight, thereby causing the lower conveying roller 3 to vibrate up and down. The steel sand adhered to the surface of the workpiece is dropped by the vibration, and the bristle assembly 8 can brush the surface of the workpiece, thereby making the surface of the workpiece better and cleaner.

[0033] Embodiment 2: This embodiment can reduce the force between the workpiece and the lower conveying roller 3. A shock-absorbing shot blasting machine includes a shot blasting chamber 2, which is installed on a bracket 1, and a shot blaster 18 is installed inside the shot blasting chamber 2; an upper conveying roller 5 is rotatably connected to the bracket 1 through a shaft; a mounting frame runs through the bracket 1, and the mounting frame is rotatably connected to the lower conveying roller 3 through a shaft; a sponge 19 is wrapped around the outer side of the lower conveying roller 3 and the upper conveying roller 5. The sponge 19 is set to reduce the force between the casting and the lower conveying roller 3 and the upper conveying roller 5, thereby achieving a shock-absorbing effect; dust pads 20 are fixed on both sides of the shot blasting chamber 2. The dust pads 20 are made of rubber and cover the inlet and outlet of the shot blasting chamber 2. .

[0034] The casting is placed on the upper conveying roller 5, and the upper conveying roller 5 moves the workpiece to the right. The dust and debris generated during the use of the shot blasting machine are reduced to overflow outside the casing through the dustproof pad 20, which is conducive to maintaining a good working environment and reducing the damage of dust to workers' health. The casting enters the shot blasting chamber 2, and the steel sand is from the loading barrel 6 to the shot blasting machine 18. The shot blasting machine 18 sprays the steel sand at high speed to the surface of the casting, thereby grinding the casting. When the casting moves to the rightmost side of the upper conveying roller 5, the casting falls downward onto the lower conveying roller 3. The casting moves to the rightmost side through the lower conveying roller 3, and the steel sand falls to the bottom of the interior of the shot blasting chamber 2 through the gap between adjacent lower conveying rollers 3.
