The blade 11 is arranged between the two wheel plates 12, and the two sides of the blade 11 are respectively connected to the two wheel plates 12.

The limiting assembly and the blade 11 may be connected by abutment, welding or integral molding.

[0067] The impeller provided in this embodiment can adjust the projection trajectory of the shot material through the cooperation of the angle-adjustable blades 11 and the limit assembly, thereby adjusting the projection range of the shot material. Compared with the prior art, it is more practical.

[0068] In this embodiment, a plurality of blades 11 are provided, and all blades 11 are sequentially spaced along the circumference of the rotation center of the wheel plate 12. Accordingly, each blade 11 is provided with a corresponding limiting component, and the limiting component is used to limit the corresponding blade 11. Each blade 11 may correspond to a set of limiting components, and in this case, the limiting components are provided on one of the wheel plates 12. Preferably, in order to ensure the stability of the blade 11, each blade 11 corresponds to two sets of limiting components, and the two sets of limiting components are provided on two wheel plates 12 respectively.

[0069] In the impeller provided in the embodiment of the utility model, the blade 11 can adjust the angle of the blade 11 by rotating on the wheel plate 12, or the angle of the blade 11 can be adjusted by sliding on the wheel plate 12.

[0070] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, it also includes a rotating shaft 13 ; the rotating shaft 13 is arranged on the blade 11 , and the blade 11 is rotatably arranged between the two wheel plates 12 through the rotating shaft 13 .

[0071] In this embodiment, a rotating shaft 13 is provided on the blade 11, and the two ends of the rotating shaft 13 are respectively connected to the two wheel plates 12, wherein the blade 11 and the rotating shaft 13 can be fixedly arranged, and the wheel plate 12 is provided with a corresponding shaft hole, and the rotating shaft 13 is rotatably connected to the corresponding shaft hole; or, a through hole is provided on the blade 11, and the rotating shaft 13 is inserted into the through hole, the blade 11 is rotatably connected to the rotating shaft 13, and the two ends of the rotating shaft 13 are fixedly connected to the wheel plate 12 by welding, riveting, clamping or plugging.

[0072] The blade 11 is rotated on the wheel plate 12 by setting the rotating shaft 13 on the blade 11. When in use, the angle of the blade 11 can be adjusted by rotating the blade 11. The structure is simple and the adjustment is convenient. When the blade 11 rotates to a preset position, the blade 11 can be fixed by a limit assembly.

[0073] Optionally, the impeller and the limit assembly provided in the embodiments of the utility model have multiple implementation modes.

[0074] In a first embodiment of the limiter assembly, Figures 1 to 4 As shown, the limiting assembly includes a first limiting member 21, a first groove 41 arranged on the wheel plate 12, and a plurality of fixing structures arranged on the wheel plate 12; one end of the first limiting member 21 is slidably arranged in the first groove 41, and the other end extends out of the first groove 41 and is used to abut against the surface of the blade 11; along the extension direction of the first groove 41, all the fixing structures are arranged in sequence at intervals, and the fixing structures are used to fix the first limiting member 21 in the first groove 41.

[0075] In this embodiment, the above-mentioned limiting assembly includes a first limiting member 21, a first groove 41 provided on the wheel plate 12, and a fixing structure provided on the wheel plate 12. Preferably, the first groove 41 is an arc groove, and its center coincides with the rotation center of the wheel plate 12. One end of the first limiting member 21 is slidably installed in the first groove 41, and the other end extends out of the first groove 41 and abuts against the surface of the blade 11. Multiple fixing structures are provided, and all the fixing structures are provided along the extension direction of the first groove 41. When the impeller rotates, the blade 11 will be tightly abutted against the first limiting member 21 under the action of inertia. Therefore, it should be noted that the rotation direction of the impeller must correspond to the first limiting member 21, that is, when the impeller rotates counterclockwise, the first limiting member 21 and the corresponding blade 11 are arranged in sequence along the counterclockwise direction, and when the impeller rotates clockwise, the first limiting member 21 and the corresponding blade 11 are arranged in sequence along the clockwise direction. When in use, the first limit member 21 is slid in the first groove 41, and then fixed by the fixing structure after sliding to the preset position. At this time, when the impeller rotates, the inclination angle of the blade 11 will change, and accordingly, the projection range of the blade 11 will change.

[0076] like Figure 2 and Figure 4 As shown in FIG. 1 , it is a comparison diagram of the change of the ejection range when the blade 11 is in two different positions in this embodiment. Figure 2 and Figure 4 In the case of a rotary vane, the impeller rotates counterclockwise.

[0077] Preferably, in this embodiment, the above-mentioned first grooves 41 are provided on both wheel plates 12, and each first groove 41 corresponds to a plurality of fixed structures. That is, two sets of position limiting components are provided corresponding to each blade 11, and the number of fixed structures in each set of position limiting components is the same in all the position limiting components, so that the projection range of each blade 11 can be the same.

[0078] Furthermore, in this embodiment, when each wheel plate 12 is provided with a first groove 41 , two first grooves 41 may share one first limiting member 21 , or each first groove 41 may be provided with a corresponding first limiting member 21 .

[0079] In the impeller provided in this embodiment, preferably, the fixing structure is a fixing hole, and the first limiting member 21 is a rod-shaped structure.

[0080] In this embodiment, the fixing structure is preferably a fixing hole, and the first limiting member 21 is a rod-shaped structure. The first limiting member 21 is connected to the fixing structure by plugging, and the structure is simple. More preferably, the fixing hole is an internal threaded hole, and the end of the first limiting member 21 is provided with a corresponding threaded structure, so that the first limiting member 21 and the fixing structure can be more secure.

[0081] When in use, the position of the first limiter 21 can be adjusted by simply separating the first limiter 21 from the fixed structure. After the adjustment is completed, the first limiter 21 can be connected to the new fixed structure. If the length of the first limiter 21 exceeds the width between the two wheel plates 12, the two wheel plates 12 can be removed from the connecting shaft first, and then the position of the first limiter 21 can be adjusted.

[0082] In the second embodiment of the limit assembly, Figure 5 and Figure 6As shown, the limiting assembly includes a second limiting member 22, a first elastic member and a second groove 42 arranged on the wheel plate 12; one end of the second limiting member 22 is connected to the side of the blade 11, and the other end extends into the second groove 42, and can slide in the second groove 42 along the extension direction of the second groove 42; the first elastic member is arranged in the second groove 42, one end of the first elastic member is connected to the inner wall of the second groove 42, and the other end is connected to the second limiting member 22; when the impeller rotates, the second limiting member 22 slides in the second groove 42 under the action of the blade 11, and the first elastic member can fix the second limiting member 22 in the second groove 42.

[0083] In this embodiment, the above-mentioned limiting assembly includes a second limiting member 22, a first elastic member and a second groove 42 provided on the wheel plate 12. Preferably, the second groove 42 is an arc groove, and its center coincides with the rotation center of the wheel plate 12. One end of the second limiting member 22 is slidably installed in the second groove 42, and part of the second limiting member 22 is located outside the second groove 42. Its function is the same as that of the first limiting member 21, and both are used to abut against the surface of the blade 11. Therefore, the structure of the second limiting member 22 can refer to the first limiting member 21, and can be a rod-shaped structure or a block-shaped structure. The two ends of the first elastic member are respectively connected to the inner wall of the second groove 42 and the second limiting member 22. When the impeller rotates, the blade 11 will counteract the second stopper 22 under the action of its own inertia force, centrifugal force and the shot material, and make the second stopper 22 slide in the second groove 42. At this time, the first elastic member applies a reaction force to the second stopper 22. When the force of the blade 11 on the second stopper 22 and the force of the first elastic member on the second stopper 22 reach a balance, the second stopper 22 will not continue to slide in the second groove 42, so that the first elastic member can fix the second stopper 22. That is, in this embodiment, the angle of the blade 11 is related to the rotation speed of the impeller and the discharge amount of the shot material. By changing the rotation speed of the impeller and the discharge amount of the shot material, the angle of the blade 11 can be adjusted, and the adjustment is more convenient.

[0084] Preferably, in this embodiment, taking the counterclockwise rotation of the impeller as an example, the first elastic member, the second adjusting member and the blade 11 are arranged in sequence in the counterclockwise direction, and the arrangement directions of the above three structures are opposite in the clockwise direction.

When the first elastic member is a spring, the two ends of the first elastic member can be connected to the inner wall of the second groove 42 and the second stopper 22 by abutting or welding.

[0086] Optionally, in this embodiment, the first elastic member may also be a glue having a certain elasticity, such as rubber.

[0087] Preferably, in this embodiment, two groups of limit assemblies can be provided. When two groups of limit assemblies are provided, one group of limit assemblies is provided on each wheel plate 12. The two groups of limit assemblies can share the same second limit member 22, or the second limit member 22 can be provided separately.

[0088] As mentioned above, the blade 11 can also be adjusted in angle by sliding on the wheel plate 12. Specifically, Figure 7 and Figure 8 As shown, along the radial direction of the wheel plate 12, the third groove 43 and the fourth groove 44 are arranged at intervals on the wheel plate 12; the side of the blade 11 is provided with a sliding member 14 corresponding to the third groove 43 and the fourth groove 44, and the blade 11 is slidably installed in the third groove 43 and the fourth groove 44 through the sliding member 14 to change the angle of the blade 11; the limiting assembly includes a second elastic member; the third groove 43 and the fourth groove 44 are both provided with a second elastic member, when the impeller rotates, the blade 11 slides in the third groove 43 and the fourth groove 44, the second elastic member in the third groove 43 can fix the sliding member 14 in the third groove 43, and the second elastic member in the fourth groove 44 can fix the sliding member 14 in the fourth groove 44.

[0089] In this embodiment, the radial direction of the wheel plate 12, that is, diffuses outward from the rotation center of the wheel plate 12. Among them, along the radial direction of the wheel plate 12, the wheel plate 12 is provided with a third groove 43 and a fourth groove 44 at intervals, and the third groove 43 and the fourth groove 44 are used to install the blade 11, and each blade 11 is correspondingly provided with a third groove 43 and a fourth groove 44. Preferably, each blade 11 is correspondingly provided with two third grooves 43 and two fourth grooves 44, that is, the two wheel plates 12 are provided with a third groove 43 and a fourth groove 44. The third groove 43 and the fourth groove 44 are also arc grooves, and their centers coincide with the rotation center of the wheel plate 12, and the length of the fourth groove 44 is greater than the length of the third groove 43. The side of the blade 11 is provided with a sliding member 14, and the sliding member 14 can be a block structure, or a shaft structure, etc. The blade 11 is slidably connected with the corresponding third groove 43 and fourth groove 44 through the sliding member 14. The above content mentioned that the third groove 43 and the fourth groove 44 are preferably provided with two, and correspondingly, sliding members 14 are provided on both sides of the blade 11. The limiting assembly includes a second elastic member, and the third groove 43 and the fourth groove 44 are provided with a second elastic member, that is, the limiting assembly includes two second elastic members. The structure of the second elastic member can be set with reference to the first elastic member, and a spring or the like can be used. The blade 11 cooperates with the third groove 43 and the fourth groove 44 by sliding, so that the blade 11 has a larger adjustment angle. The limiting assembly can be provided in a group, and when each blade 11 corresponds to two third grooves 43 and two fourth grooves 44, the limiting assembly can be provided in one group or in two groups.

[0090] When in use, the blade 11 will slide in the third groove 43 and the fourth groove 44 under the action of its own inertia force, centrifugal force and other forces and the action of the shot material. At this time, the second elastic member applies a reaction force to the sliding member 14. When the force between the blade 11 and the second elastic member reaches a balance, the blade 11 will not continue to slide in the third groove 43 and the fourth groove 44, so that the second elastic member fixes the blade 11. That is, this embodiment is the same as the above embodiment, and the blade 11 is fixed by the elastic member, and the angle of the blade 11 can be adjusted in real time by changing the rotation speed of the impeller and the discharge amount of the shot material.
