[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a PC material premixing device, including a housing 1. A discharge valve is provided at the bottom of the housing 1. By opening the discharge valve, the PC material that has been mixed inside the housing 1 is discharged from the bottom of the housing 1. A telescopic hose 2 is fixedly connected to the side wall of the top of the housing 1. The telescopic hose 2 is prior art. When the feeding box 3 moves with the connecting frame 44, the telescopic hose 2 will automatically extend and retract. The end of the telescopic hose 2 away from the housing 1 is fixedly connected to the feeding box 3. A feed inlet 6 is provided at the top of the outer wall of the housing 1. A stirring shaft 7 is rotatably connected to the inner side wall of the housing 1. By providing the stirring shaft 7, multiple PC raw materials can be mixed when they enter the interior of the housing 1. A collection component 5 is provided at the bottom of the outer wall of the feeding box 3. A shaking mechanism 4 is provided at the top of the housing 1.

[0033] Reference Figure 2 and Figure 3 The shaking mechanism 4 includes a motor 41, the output shaft of which is fixedly connected to a half gear 42. The half gear 42 is fixedly connected to the rotation center shaft of the stirring shaft 7. When the motor 41 drives the half gear 42 to rotate, it also drives the stirring shaft 7 to rotate synchronously, thereby mixing the PC raw materials entering the shell 1. A bracket is provided on the outer side wall of the feed inlet 6. The motor 41 is fixedly connected to the bracket on the surface of the feed inlet 6, and the half gear 42 is rotatably connected to the outer wall of the shell 1. At the top, a rack 43 meshes with the outer wall of the half gear 42. A connecting frame 44 is fixedly connected to the end of the rack 43 away from the half gear 42. The tooth blocks on the surface of the half gear 42 mesh with the rack 43, and the number of teeth on the rack 43 is only one-third of its outer arc surface. At the same time, through the rotation of the half gear 42, the tooth blocks mesh with the upper rack 43, thereby causing the rack 43 to pull the corresponding connecting frame 44 to move outward. When it rotates to the lower side, it will mesh with the lower rack 43 to make the corresponding connecting frame 44 move outward.

[0034] Reference Figure 3 The connecting frame 44 is elastically connected to the inner wall of the top of the housing 1 via a return spring 45. One end of the return spring 45 is fixedly connected to the outer wall of the bottom of the connecting frame 44, and the other end of the return spring 45 is fixedly connected to the inner wall of the top of the housing 1. The function of the return spring 45 is to reset the connecting frame 44 after the rack 43 is disengaged from the half gear 42, so that the rack 43 returns to its initial position and waits for the next engagement movement. This process is repeated so that the PC material inside the feeding box 3 can fully enter the interior of the housing 1, thereby preventing it from being blocked at the telescopic hose 2. The inner wall of the bottom of the connecting frame 44 is slidably connected to a guide rod 46. The connecting frame 44 is slidably connected to the inner wall of the top of the housing 1, and the guide rod 46 is fixedly connected to the inner wall of the top of the housing 1.

[0035] ReferenceFigure 1 and Figure 4 The collection component 5 includes a collection box 51. A lever 53 is elastically connected to the inner wall of the collection box 51 via a limiting spring 52. One end of the limiting spring 52 is fixedly connected to the outer wall of the lever 53, and the other end is fixedly connected to the inner side wall of the collection box 51. The limiting spring 52 automatically resets the lever 53 after it has been moved. The lever 53 is slidably connected to the inner side wall of the collection box 51. An insert 55 passes through and is slidably connected to the inner wall of the collection box 51. A hinge rod 54 is hinged to the inner wall of the lever 53. The insert 55 is hinged to the end of the hinge rod 54 away from the lever 53. When the lever 53 moves, it pulls the insert 55 downwards along the inner wall of the collection box 51 via the hinge rod 54, thereby disengaging it. The feeding box 3 has a through hole at the bottom, which allows the collection box 51 to be disassembled as a whole. The top of the feeding box 3 has a sliding groove, and the outer wall of the top of the collection box 51 contacts the inner wall of the sliding groove. The bottom of the outer wall of the feeding box 3 has a through hole, and the outer wall of the top of the insert block 55 is inserted into the inner wall of the through hole. The insertion of the two allows the collection box 51 to be fixed at the bottom of the feeding box 3, so as to collect the impurities of the PC material filtered by the filter plate 8. The inner side wall of the feeding box 3 is fixedly connected to the filter plate 8. By setting the filter plate 8, the dust and small stones in the PC material can be filtered by the filter plate 8, so as to prevent them from entering the interior of the housing 1 together, which would cause the quality of the mixed PC material to deteriorate.

[0036] Working principle: When PC material enters from the feeding box 3, impurities such as dust and small stones are filtered by the filter plate 8. The filtered impurities fall into the collection box 51. When the collection box 51 needs to be cleaned, the lever 53 is moved. The lever 53 moves against the elastic force of the limit spring 52 and pulls the insert 55 downward on the inner wall of the collection box 51 through the hinge rod 54, so that the insert 55 disengages from the through hole at the bottom of the feeding box 3. At this time, the collection box 51 can be disassembled as a whole for cleaning. After cleaning, the top of the collection box 51 is aligned with the top slide groove of the feeding box 3 and inserted. Then the lever 53 is released. Under the action of the limit spring 52, the lever 53 automatically resets and drives the insert 55 to move upward. The outer wall of the top of the insert 55 is inserted into the through hole at the bottom of the feeding box 3, fixing the collection box 51 at the bottom of the feeding box 3, and continuing to collect the impurities filtered by the filter plate 8.

[0037] Meanwhile, when the feeding efficiency of the feeding box 3 is low, after the motor 41 starts, it drives the half gear 42 to rotate. Since the half gear 42 is fixed to the rotation center axis of the stirring shaft 7, the stirring shaft 7 will rotate synchronously with the half gear 42 to mix the PC raw materials entering the shell 1. During the rotation of the half gear 42, its surface teeth mesh with the rack 43. Because the number of teeth of the rack 43 is only one-third of its outer arc surface, when the half gear 42 rotates, the teeth mesh with the upper rack 43, causing the rack 43 to pull the corresponding... The connecting frame 44 moves outward; when it rotates to the lower side, it will engage the lower rack 43, causing the corresponding connecting frame 44 to move outward again. When the tooth block of the half gear 42 disengages from the rack 43, the return spring 45 takes effect, driving the connecting frame 44 to reset, so that the rack 43 returns to the initial position to wait for the next engagement. The connecting frame 44 is connected to the feeding box 3. This reciprocating motion causes the feeding box 3 to shake, thereby preventing the PC material from getting blocked at the telescopic hose 2 and ensuring that the PC material can fully enter the interior of the housing 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
