Description

Technical Field

[0001] The utility model relates to the technical field of steel belt surface treatment, in particular to a steel belt shot blasting machine. Background Art

[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean the castings. Almost all steel castings, gray castings, malleable castings, ductile iron castings, etc. need to be shot blasted. This is not only to remove the oxide scale and sticky sand on the surface of the castings, but also an indispensable preparatory process before the quality inspection of the castings. According to modern metal strength theory, increasing the dislocation density inside the metal is the main direction to improve the strength of the metal. Practice has proved that shot blasting is an effective process for increasing the dislocation structure of the metal.

[0003] The shot blasting machines on the market generally accumulate the shot in a silo. After the equipment is started, the shot enters the sandblasting component through a pipe and is thrown down at high speed to impact the surface of the material object to achieve surface treatment of the material. When there are more shot accumulated in the silo or the feeding speed is faster, the shot will block the pipe, and some of the shot will accumulate at the bottom. If it is not used for a long time, impurities will be generated and it cannot be used normally, which reduces the efficiency of shot blasting and affects the normal operation of the shot blasting machine.

[0004] Therefore, the utility model provides a steel belt shot blasting machine to meet the demand. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a steel belt shot blasting machine which, by setting a two-stage stirring component, can not only stir the materials accumulated in the silo to prevent the clogging thereof, but also can make corresponding adjustments according to the feeding speed and the feeding amount, thereby making the conveying of the shot materials in the whole shot blasting process more flexible and more targeted.

[0038] In this embodiment, if Figure 5 to Figure 6 As shown, the secondary stirring assembly includes a push rod base 6 fixedly connected to one side of the storage tank 5, the top of the push rod base 6 is fixedly connected to an electric push rod 7, the end of the electric push rod 7 close to the storage tank 5 is fixedly connected to a conical plate 11, both sides of the conical plate 11 are fixedly connected to fixed blocks 12, both sides of the conical plate 11 are slidably connected to limit plates 13 that are adapted to the shape of the fixed blocks 12, one side of the limit plate 13 is fixedly connected to a first fixed plate 14, and one side of the first fixed plate 14 is fixedly connected to a secondary stirring plate 15. The secondary stirring assembly is mainly used for the situation where there are too many pills in the storage tank 5 or the feeding speed is too fast, so as to ensure that the pills are not It will accumulate at the entrance of the conveying pipe 4. The fixed blocks 12 on both sides of the conical plate 11 are adapted to the shape of the slide groove in the middle of the two groups of limit plates 13. Therefore, the conical plate 11 can slide from left to right in the limit plate 13 under the action of the electric push rod 7. Since the conical plate 11 is adapted to the overall shape of the limit plate 13, during the pushing process, the two groups of limit plates 13 will move to both sides respectively. Similarly, the first fixed plate 14 and the second fixed rod 17 connected thereto also move to both sides. The staff can adjust the length of the electric push rod 7 according to the feeding speed and quantity of the shot material, thereby adjusting the position of the first fixed plate 14 and the second fixed rod 17.
