Description

Technical Field

[0001] The utility model relates to the field of shot blasting machines, in particular to a shot blasting machine blade which is convenient for quick disassembly and assembly. Background Technique

[0002] A shot blasting machine is a casting equipment that uses high-speed projectiles thrown by a shot blasting device to clean or strengthen the surface of castings, and it can perform operations such as knocking out sand, removing cores, and cleaning on castings. Among them, the blade of the shot blasting machine, as one of the main components in the shot blasting machine, is in long-term contact with high-speed projectiles. The existing blades usually need to be installed by bolts passing through the blades and docking with the impeller, and the disassembly and assembly are relatively troublesome. The Chinese utility model patent with the application number 202323103936.0 discloses a shot blasting machine blade that is convenient for positioning and installation. By fixing the blade body through a fixing mechanism, it is not necessary to use a drill to rotate the bolts, and it is also not necessary for the staff to worry about the random movement of the blade body during installation, thus completing the installation of the shot blasting machine blade, saving time and effort, and thus playing a role in facilitating positioning and installation. The splashing raw materials are blocked by a baffle plate, and the falling sand during grinding is quickly discharged through a guiding cavity, thereby preventing the falling sand and flying dust from splashing into the interior of the shot blasting machine impeller and then contacting the core power components such as the motor and causing damage to them, thus playing a role in facilitating protection when the shot blasting machine blade is in use.

[0003] The above-mentioned shot blasting machine blade can play a role in facilitating quick positioning and installation. However, it is found that it has defects during use: its positioning structure is relatively complex, and once a failure occurs, the repair is relatively difficult. Moreover, the blade is an integral structure as a whole. Sometimes, only a little damage occurs at the end of the blade, and the entire blade needs to be replaced, which is relatively wasteful of materials. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a shot blasting machine blade that is convenient for quick disassembly and assembly. This shot blasting machine blade can solve the problems put forward in the background technique, such as the relatively complex positioning structure, once a failure occurs, the repair is relatively difficult, and the blade is an integral structure as a whole. Sometimes, only a little damage occurs at the end of the blade, and the entire blade needs to be replaced, which is relatively wasteful of materials.

[0005] To achieve the above object, the utility model provides the following technical solution: A shot blasting machine blade that is convenient for quick disassembly and assembly, including a blade body with guiding cavities provided on both the left and right sides.

[0007] As a preferred technical solution, the first splicing structure includes a clamping block fixed to the inner end face of the blade support body, and a first clamping groove matched with the clamping block is embedded in the outer end face of the blade support body.

[0008] As a preferred technical solution, the clamping block is of a vertical structure, and its cross-section is an inverted T-shaped structure. The first clamping groove is a vertical strip-shaped structure with a side opening and an upper opening, and its cross-section is an inverted T-shaped structure.

[0009] As a preferred technical solution, the second splicing structure includes a clamping block at the inner end of the blade support body, and a second clamping groove matched with the clamping block is embedded in the impeller fixing seat. The second clamping groove has the same structure as the first clamping groove.

[0010] As a preferred technical solution, a first screw for fixing the clamping block is screwed inward on the outer surface of the blade support body on one side of the first clamping groove.

[0011] As a preferred technical solution, a second screw for fixing the clamping block is screwed upward on the bottom surface of the impeller fixing seat below the second clamping groove.

[0012] As a preferred technical solution, protective strips are adhesively bonded at intervals on the left and right sides and the upper and lower sides of the blade body respectively, and the protective strips penetrate through the blade body inside and outside.
