[0002] Shot blasting machine is a kind of equipment used for surface treatment of steel wire. It throws steel shot or other abrasives through the high-speed rotating shot blasting wheel. The steel shot or other abrasives collide with the steel wire during the movement to achieve the purpose of cleaning and strengthening the surface of the steel wire. The impeller of the shot blasting machine is usually composed of multiple blades, which are installed on a central axis to form a fan-like structure.

[0003] However, when the impeller of the shot blasting machine is in use, as mentioned in the authorization publication number CN 218254645 U "A Shot Blaster", the blades are easily damaged by the impact of steel shots or other abrasives.

[0008] Furthermore, each of the accommodating holes is an arc-shaped hole, and the multiple accommodating holes are located on the same circular ring. The circular ring where the multiple accommodating holes are located is coaxial with the wheel body, and the limiting rod is an arc-shaped rod body whose inner and outer end surfaces slide in contact with the accommodating holes; the limiting hole is a rectangular hole, and the cross-section of the limiting rod is a rectangle corresponding to the rectangular hole.

[0009] Furthermore, the wheel body is provided with a through hole for each blade to pass through, and a plurality of through holes are arrayed along the center of the wheel body. Both ends of the blade outside each through hole are connected to baffles, and the two baffles on the same blade are parallel, and there is a spacing between both ends of the baffle and the connected blade.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model drives the limit rod to limit and fix the corresponding blade by rotating the bolt. When any blade needs to be replaced, the bolt corresponding to the damaged blade is removed. Under the restoring force of the spring, the limit rod no longer limits the corresponding blade, the damaged blade is released from limit, the blade is removed, and a new blade is inserted into the through hole. The limit rod is driven by the bolt to limit the new blade. After the utility model rotates the bolt, the blade can be limited or released. The installation and disassembly of the blade are convenient, time is saved, and efficiency is improved.

[0014] The head of the bolt of the utility model is located in the head of the countersunk threaded hole.

The limiting rod 7 is circumferentially slidably arranged in the corresponding accommodating hole 2. One end of the limiting rod 7 extends into the limiting hole 6 of the blade 3 corresponding to the accommodating hole 2. The other end of the limiting rod 7 is connected to the side of the accommodating hole 2 via a spring 9. The outer end surface of each limiting rod 7 is recessed with an inclined groove 10. The depth of the inclined groove 10 is greater near one end of the spring 9 than the other end. The bottom surface of the inclined groove 10 is the side surface opposite to the outer end opening of the inclined groove 10. The wheel body 1 opposite to the bottom surface of the inclined groove 10 is threadedly connected with a bolt 8, and the end of the bolt 8 contacts the bottom surface of the inclined groove 10.

[0023] The center of the wheel body 1 is fixedly provided with a central shaft 11, and circular plates 12 are fixedly mounted on the central shafts on both sides of the wheel body 1. The openings at both ends of each receiving hole 2 are blocked by the circular plates 12 on the same side to prevent foreign matter from entering the receiving hole.

[0024] Each of the accommodating holes 2 is an arc-shaped hole, and multiple accommodating holes 2 are located on the same circular ring. The circular ring where the multiple accommodating holes 2 are located is coaxial with the wheel body 1. The limiting rod 7 is an arc-shaped rod body whose inner and outer end surfaces slide in contact with the accommodating holes 2; the limiting hole 6 is a rectangular hole, and the cross-section of the limiting rod 7 is a rectangle corresponding to the rectangular hole.

[0025] The wheel body 1 is provided with a through hole 5 for each blade to pass through, the through hole 5 is a rectangular hole, the blade 3 is a rectangular plate whose side contacts the through hole 5, and multiple through holes 5 are arrayed along the center of the wheel body 1. Both ends of the blade 3 outside each through hole 5 are connected to a baffle 13, the baffle 13 is a rectangular plate, the two baffles 13 on the same blade 3 are parallel, and there is a spacing between the two ends of the baffle 13 and the connected blade 3.

[0026] The end of the bolt 8 on each limiting member passes through the circumferential surface of the wheel body 1 and the outer end surface of the receiving hole 2 in sequence. The wheel body 1 is provided with a countersunk threaded hole 14 corresponding to the bolt 8; the head of the bolt 8 is provided with a slot 15.

[0027] The rod diameter of the bolt 8 matches the width of the inclined groove 10. When the head of the bolt 8 is located in the head of the corresponding countersunk threaded hole 14, the end of the bolt 8 contacts the bottom surface of the corresponding inclined groove 10 close to one end of the spring 9. The spring 9 is in a stretched state, and the other end of the limiting rod 7 where the inclined groove 10 is located extends into the limiting hole 6 on the corresponding blade 3.

[0028] When the spring 9 is in a natural state, the limiting rod 7 connected to the spring 9 is separated from the limiting hole 6 on the corresponding blade 3 .

[0029] During installation, use the end of a flat-blade screwdriver to extend into the flat-blade slot and unscrew the bolt 8 on each limiting piece. At this time, the bottom surface of the inclined slot 10 on each limiting rod 7 is no longer pressed by the end of the corresponding bolt 8, and the spring 9 is in a natural state; after the blade 3 is inserted into a through hole 5, the limiting hole 6 on the blade 3 is located in the corresponding accommodating hole 2, and the countersunk threaded hole 14 on the limiting piece corresponding to the blade 3 is used to thread the bolt 8. The end of the bolt 8 extends into the corresponding inclined slot and first contacts the bottom end of the inclined slot 10 with a shallow depth. During the process of screwing the bolt 8 in, the end of the bolt 8 The bottom surface of the inclined groove 10 is pressed against the top, so that the limiting rod 7 where the inclined groove 10 is located moves toward the limiting hole 6 of the corresponding blade 3. After the head of the bolt 8 is completely located in the head of the countersunk threaded hole 14, one end of the limiting rod 7 extends into the limiting hole 6. At this time, the spring 9 is in a stretched state, and the blade 3 is fixed by limiting. Repeat the above process to limit and fix each blade 3. Moreover, when in use, the head of the bolt 8 is located in the head of the countersunk threaded hole 14. When the utility model throws steel shots, the steel shots are not easy to drive the bolt 8 to rotate, thereby keeping the limiting rod 7 fixed to the corresponding blade 3.

[0030] When any blade 3 is damaged and needs to be replaced, remove the bolt 8 corresponding to the damaged blade 3. Under the restoring force of the spring 9, one end of the limiting rod 7 disengages from the limiting hole 6 of the corresponding blade 3, and the blade 3 is no longer limited. The damaged blade 3 can be pulled out of the perforation 5, and the above installation process is repeated to limit and fix the new blade 3.
