The shot blasting nozzle of the shot blasting machine is located inside the box body, and the bottom of the box body is connected to the feed port of the shot blasting device. A suspension rack is provided on the upper side wall of the box body, and hooks for hanging metal parts are provided on the suspension rack. The shot blasting nozzle sprays abrasive grains. After the abrasive grains contact the workpiece, they fall to the bottom of the box body.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] The following combines the attached Figures 1-3A further detailed description of the present application is provided.
[0033] An embodiment of the present application discloses a shot blasting machine for metal processing. Referring to Figure 1 and Figure 2 , the shot blasting machine for metal processing includes a box body 1 and a shot blasting device 2. The shot blasting device 2 is provided with a shot blasting nozzle 21. The shot blasting nozzle 21 is located inside the box body 1. A screen 3 is arranged inside the box body 1. The screen 3 is inclined. And a vibration assembly 4 for driving the screen 3 to vibrate is arranged on the box body 1. An outlet hole 11 is opened on the box body 1 near the lower side of the screen 3. The feed inlet of the shot blasting device 2 is communicated with the outlet hole 11. The shot pellets ejected from the shot blasting nozzle 21 fall onto the screen 3. The shot pellets can slide along the inclined direction of the screen 3 towards the outlet hole 11. The broken shot pellets can fall from the mesh holes of the screen 3. The operator starts the vibration assembly 4 to drive the screen 3 to vibrate, which can accelerate the falling of the broken shot pellets on the screen 3, reduce the stagnation of the shot pellets rolling on the screen 3, improve the separation effect of the broken shot pellets, enable the relatively intact shot pellets to fall into the outlet hole 11, the shot blasting device 2 can recycle the relatively intact shot pellets, ensure the impact force of the shot pellets on the metal workpiece, and improve the problem that it is easy to reduce the shot blasting efficiency of the metal workpiece.
[0034] A bracket 5 is suspended on the upper side wall of the box body 1. Hooks are arranged on the bracket 5. With the help of the bracket 5, the metal workpiece can be suspended.
[0035] One side of the screen 3 close to the outlet hole 11 is the lower side of the screen 3. And the lower side of the screen 3 is located inside the outlet hole 11. When the shot blasting slides on the screen 3, it can ensure that the shot pellets on the screen 3 enter the shot blasting device 2 through the outlet hole 11, reducing the spillage of the shot pellets.
[0036] Referring to Figure 1 and Figure 2 , the lower side of the screen 3 is hinged to the inner side wall of the outlet hole 11. The hinge axis of the screen 3 is horizontal. The vibration assembly 4 is used to control the lifting of the side of the screen 3 away from the outlet hole 11. The operator controls the side of the screen 3 away from the outlet hole 11 to reciprocally lift and lower, so that the screen 3 rotates along its hinge axis, and the reciprocating vibration of the screen 3 can be realized.
[0037] Referring to Figure 2 and Figure 3 , a mounting plate 6 is fixedly installed on the side of the screen 3 away from the outlet hole 11. Mounting holes 61 are opened on the mounting plate 6. The vibration assembly 4 includes a driving rod 41 and a driving member 42 for driving the driving rod 41 to lift and lower. The driving rod 41 is located inside the mounting hole 61. When the driving rod 41 lifts and lowers, it can make the mounting plate 6 drive the screen 3 to lift and lower, thus realizing the reciprocating lifting of the higher side of the screen 3.
[0038] The mounting holes 61 are waist-shaped holes, and the length direction of the mounting holes 61 is parallel to the screen mesh 3. The driving member 42 is a turntable rotatably mounted inside the box body 1, and the rotation axis of the turntable is parallel to the hinge axis of the screen mesh 3. The driving rod 41 is fixedly connected to the turntable, the axis of the driving rod 41 is parallel to the axis of the turntable, and the driving rod 41 is not coaxial with the turntable. When the turntable rotates unidirectionally, it can drive the driving rod 41 to reciprocate up and down.
[0039] Refer to Figure 2 and Figure 3 The vibration assembly 4 further includes a motor. The motor is mounted outside the box body 1, and the output shaft of the motor is fixedly connected to the turntable coaxially. When the operator starts the motor, it can drive the turntable to rotate, thereby realizing the automatic vibration of the screen mesh 3.
[0040] A bearing 411 is provided on the driving rod 41. The bearing 411 is located within the waist-shaped hole, and the diameter of the bearing 411 is smaller than the width of the mounting hole 61. When the driving rod 41 moves up and down, the driving rod 41 drives the bearing 411 to reciprocate along the length of the mounting hole 61, and the bearing 411 rotates. The bearing 411 reduces the frictional loss between the driving rod 41 and the inner side wall of the waist-shaped hole.
[0041] A garbage box 7 for containing the broken abrasive grains is mounted at the bottom of the box body 1, and a mounting opening 12 for the garbage box 7 to enter and exit is provided on the side wall of the box body 1. By means of the garbage box 7, the broken abrasive grains are picked up, which is convenient for the operator to centrally process the broken abrasive grains.
[0042] To facilitate the operator to push and pull the garbage box 7, rollers 71 are provided on the bottom side of the garbage box 7. When the operator pushes and pulls the garbage box 7, the rollers 71 rotate, which is convenient for the operator to load or take out the garbage box 7.
[0043] To increase the rolling distance of the abrasive grains on the screen mesh 3, a diversion plate 8 is provided on the upper side of the screen mesh 3. The diversion plate 8 is fixedly connected to the inner side of the box body 1, and the diversion plate 8 is inclined. The inclination direction of the diversion plate 8 is opposite to the inclination direction of the screen mesh 3. After the broken abrasive grains fall onto the diversion plate 8, they will slide along the diversion plate 8 and fall onto a higher area of the screen mesh 3, ensuring the moving distance of the abrasive grains on the screen mesh 3 and ensuring the screening effect of the screen mesh 3 on the abrasive grain debris in the abrasive grains.
[0044] Refer to Figure 2 and Figure 3 An elastic cloth 9 is connected between the higher side of the screen mesh 3 and the inner side wall of the box body 1. After the abrasive grains fall from the diversion plate 8, the elastic cloth 9 can ensure that the abrasive grains fall onto the screen mesh 3. The elastic cloth 9 has elasticity and can contract along with the vibration of the screen mesh 3.
[0045] The implementation principle of the shot blasting machine for metal processing in the embodiments of the present application is as follows: The abrasive grains ejected from the shot blasting nozzle 21 fall onto the screen 3. The abrasive grains can slide along the inclined direction of the screen 3 towards the discharge hole 11. The broken abrasive grains can fall through the mesh holes of the screen 3. The operator starts the vibration assembly 4 to drive the screen 3 to vibrate, which can accelerate the falling of the broken abrasive grains on the screen 3, reduce the stagnation of the rolling of the abrasive grains on the screen 3, improve the separation effect of the broken abrasive grains, enable the relatively intact abrasive grains to fall into the discharge hole 11, and the shot blasting machine 2 can recycle the relatively intact abrasive grains, ensuring the impact force of the abrasive grains on the metal workpiece and improving the problem that it is easy to reduce the shot blasting efficiency of the metal workpiece.
