[0022] As Figure 1 , Figure 2 and Figure 3The utility model provides a throw material impeller, the throw material impeller includes the front wheel cover 10 and rear wheel disc 20 who sets up in parallel and interval, a plurality of evenly spaced arrangement blade 30 in the circumference is arranged between the front wheel cover 10 with rear wheel disc 20, a plurality of through -hole 40 are arranged on the front wheel cover 10 and rear wheel disc 20 respectively, a plurality of through -hole 40 on the front wheel cover 10 and a plurality of through -hole 40 on the rear wheel disc 20 respectively for a plurality of both ends of blade 30 correspondingly pass through, and both ends of each blade 30 are welded and fixed with the side of the front wheel cover 10 and the rear wheel disc 20 respectively away from each other.

[0023] In combination Figure 1 And Figure 3 As shown in the utility model provides a throw material impeller, rear wheel disc 20 is provided with coaxial connection axle disc 60, the throw material impeller is connected with power system transmission through axle disc 60, rotates around its own axis after obtaining power and realizes throwing material through a plurality of blades 30.

[0024] In the technical scheme provided by the utility model, by setting through -hole 40 on the front wheel cover 10 and rear wheel disc 20 respectively for the both ends of blade 30 correspondingly pass through, and both ends of blade 30 are welded and fixed with the side of the front wheel cover 10 and the rear wheel disc 20 respectively away from each other, compared with the both ends of blade 30 in the prior art are only welded and fixed with the opposite surface of the front wheel cover 10 and the rear wheel disc 20, the throw material impeller provided by the utility model has higher structural strength, can effectively prevent the impact of material from causing blade 30 to open weld, even the problem of fracture.

[0025] Compared with the prior art, the throw material impeller provided by the utility model has the advantage of not being easily damaged, thereby reducing maintenance cost and ensuring the continuity of throwing material operation.

[0026] In some embodiments, both ends of each blade 30 are welded and fixed with the opposite side of the front wheel cover 10 and the rear wheel disc 20. By the above setting, the connection strength between blade 30 and the front wheel cover 10 and the rear wheel disc 20 can be further improved, preventing the impact of material from causing blade 30 to open weld, even the problem of fracture.

[0027] It should be noted that in the embodiments of the utility model, the length of the through -hole 40 can be set to be consistent with the width of the blade 30, so that the end of the blade 30 can be inserted into the through -hole 40 to meet the requirements of welding fixation, but in this case, the front wheel cover 10 and the rear wheel disc 20 may be affected by the length of the through -hole 40, and the end of the blade 30 inserted into the through -hole 40 also has the disadvantage of inconvenient welding operation.

[0028] In some embodiments of the utility model, the blade 30 includes blade body 31 and the convex part 32 set at both ends of blade body 31, the convex part 32 at both ends of blade body 31 corresponds with the through hole 40 on front wheel cover 10 and rear wheel disc 20 respectively, the convex part 32 at both ends of blade body 31 is set to be able to insert through hole 40 and is welded and fixed with the side of front wheel cover 10 and rear wheel disc 20 respectively that is away from each other, in this embodiment, the end of blade 30 is not inserted into through hole 40 entirely, so the through hole 40 on front wheel cover 10 and rear wheel disc 20 does not need to be set very long, thereby can ensure structural strength, and the both ends of blade body 31 can form stop cooperation after the convex part 32 inserts through hole 40, facilitate positioning, thereby facilitate welding operation.

[0029] In some embodiments, the thickness of the convex part 32 is consistent with the width of the through hole 40. By the above setting, it is ensured that the blade body 31 is not easy to be skewed after being inserted into the through hole 40 by the convex part 32, which is beneficial to guarantee the welding quality.

[0030] In some embodiments, each of the blades 30 is perpendicular to the plate surface of the front wheel cover 10 and the rear wheel disc 20.

[0031] The inventor of the present application has also found in practice that the blade 30 is connected to the front wheel cover 10 and the rear wheel disc 20 only by its two ends, and lacks support at the middle position, which can easily lead to instability of the blade 30 and increase the risk of opening welding of the blade 30 during the material throwing operation due to the long-time impact of the material. Therefore, in some embodiments, a reinforcing sheet 50 is arranged between adjacent two blades 30, and the two ends of the reinforcing sheet 50 are welded and fixed with the adjacent two blades 30 respectively. The inventor has found that by welding and fixing the reinforcing sheet 50 between the adjacent two blades 30, the connection strength of the blade 30 is further improved.

[0032] In some embodiments, a plurality of the reinforcing sheets 50 are arranged in the same plane. That is, the reinforcing sheets 50 between a plurality of adjacent two blades 30 in the circumferential direction are in the same plane, so that when the blade 30 bears the impact of the material, a part of support can be provided between the adjacent reinforcing sheets 50, further improving the strength of the blade 30 and preventing the opening welding problem caused by deformation.

[0033] In some embodiments, the reinforcing sheet 50 is an integral ring structure, and the outer side of the blade 30 is provided with a clamping groove 33 opening outward for clamping and welding of the reinforcing sheet 50. When assembling, the blade 30 is assembled on the integral ring structure of the reinforcing sheet 50 through the clamping groove 33 arranged thereon, and then welded and fixed.

[0034] The reinforcing sheet 50 mainly plays a role of reinforcing the rigidity of the blade 30, and the width of the reinforcing sheet 50 is not suitable to be set too large, so as to avoid affecting the material throwing effect of the blade 30. In some embodiments, the width of the reinforcing sheet 50 is smaller than the width of the blade 30. Further, the width of the reinforcing sheet 50 is 1 / 4-1 / 3 of the width of the blade 30; and further preferably 1 / 4.

[0035] The utility model also provides a kind of material throwing machine, and the material throwing machine has above-mentioned material throwing impeller.

[0036] It can be understood that, by the material throwing machine with the above-mentioned material throwing impeller, the rigidity of the blade 30 is obviously strengthened, the frequency of failure of the blade 30 is effectively reduced, the maintenance cost is reduced, the continuity of material throwing operation is ensured, and the production efficiency is indirectly improved.

[0037] The preferred embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to this. Within the technical concept range of the utility model, the technical scheme of the utility model can be subjected to various simple modifications, and in order to avoid unnecessary repetition, the utility model will not be described again for various possible combination modes. However, these simple modifications and combinations should also be regarded as the disclosed content of the utility model, and all belong to the protection range of the utility model.
