In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] In the following, in conjunction with the accompanying drawings, a water-in-sand mixer provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0052] Embodiment 1:

[0053] like Figures 1 to 3 As shown, an embodiment of the present application provides a water-bagged sand mixer, including a driving motor 1, a rotating shaft 2, a feed port 3, a discharge port 4, support legs 5, and a mixing tank 6, characterized in that it also includes a mixing component 7, which is used to prevent the material in the mixing tank 6 from clumping during the mixing process; and a rolling component 8, which is used to reduce the size of the material entering the mixing tank 6.

[0054] Furthermore, the stirring assembly 7 includes a stirring shaft system 71 , which is disposed inside the stirring tank 6 ; and a stirring blade 72 , which is disposed on the stirring shaft system 71 .

[0055] Furthermore, the stirring shaft system 71 includes a fourth stirring shaft 714, the top end of which is connected to the stirring tank 6; a third stirring shaft 713, which is rotationally connected to the fourth stirring shaft 714; a second stirring shaft 712, which is rotationally connected to the third stirring shaft 713; and a first stirring shaft 711, which is rotationally connected to the second stirring shaft 712.

[0056] Furthermore, the stirring assembly 7 also includes a transmission gear set 73, which is used to change the rotation direction and rotation speed of the stirring shaft system 71.

[0057] Furthermore, the transmission gear set 73 includes an internal gear set 74 for changing the rotation direction of the second stirring shaft 712 and the third stirring shaft 713 ; and an external gear set 75 for changing the rotation direction of the first stirring shaft 711 and the fourth stirring shaft 714 .

[0058] Furthermore, the internal gear set 74 includes: a third gear 741, which is arranged at one end of the rotating shaft 2 away from the driving motor 1; a fourth gear 742, which is meshed and connected with the side surface of the third gear 741, and its lower surface is fixedly connected to the second stirring shaft 712; a fifth gear 743, which is meshed and connected with the side surface of the third gear 741, and its lower surface is fixedly connected to the third stirring shaft 713.

[0059] Furthermore, the external gear set 75 includes: a first gear 751, which is set on the side surface of the rotating shaft 2; a second gear 752, which is meshed and connected with the side surface of the first gear 751, and its lower surface is fixedly connected to the first stirring shaft 711; a sixth gear 753, which is meshed and connected with the side surface of the first gear 751, and its lower surface is fixedly connected to the fourth stirring shaft 714.

[0060] Furthermore, the stirring blade 72 has a spiral shape.

[0061] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the side surface of the rotating shaft 2 is fixedly connected with the first gear 751, and the rotating shaft 2 drives the first gear 751 to rotate. The surface side of the first gear 751 is meshedly connected with the second gear 752 and the sixth gear 753, and the second gear 752 is located at the lower side of the first gear 751, and the sixth gear 753 is located at the upper side of the first gear 751, so that the rotation of the first gear 751 will drive the second gear 752 and the sixth gear 753 to rotate in opposite directions, effectively increasing the mixing efficiency of the material. The radius and the number of gear teeth of the second gear 752 and the sixth gear 753 are the same, and are both smaller than the radius and the number of gear teeth of the first gear 751, which can increase the rotation speed of the second gear 752 and the sixth gear 753;

[0062] The end of the rotating shaft 2 away from the driving motor 1 is fixedly connected with the third gear 741, and the third gear 741 will rotate synchronously with the first gear 751. The surface side of the third gear 741 is meshed with the fourth gear 742 and the fifth gear 743, and the fourth gear 742 is located at the lower side of the third gear 741, and the fifth gear 743 is located at the upper side of the third gear 741, so that the rotation of the third gear 741 will drive the fourth gear 742 and the fifth gear 743 to rotate in opposite directions, and the fourth gear 742 and the second gear 752 have the same rotation direction. Due to the radius of the third gear 741 The number of teeth is half of that of the first gear 751, so the rotation speed of the fourth gear 742 and the fifth gear 743 is different from that of the second gear 752 and the sixth gear 753. The lower surfaces of the second gear 752 and the sixth gear 753 are fixedly connected to the first stirring shaft 711 and the fourth stirring shaft 714, respectively. The lower surfaces of the fourth gear 742 and the fifth gear 743 are fixedly connected to the second stirring shaft 712 and the third stirring shaft 713, respectively. Stirring blades 72 are provided on the stirring shaft system 71. Through different rotation speeds and rotation directions, the stirring effect of the material is increased to avoid internal material agglomeration.

[0063] Embodiment 2:

[0064] like Figures 1 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the crushing assembly 8 includes a supporting cross bar 81, which is arranged on the first stirring shaft 711; a crushing component 82, which is arranged on the supporting cross bar 81; and a screen 83, which is arranged on the stirring tank 7.

[0065] Furthermore, the rolling assembly 8 also includes: a fixing structure 84 , which is arranged at the connection between the first stirring shaft 711 and the supporting cross bar 81 .

[0066] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during the feeding stage, the material will reach the rolling assembly 8 through the feed port 3, and the qualified material will pass through the screen 83 and fall into the mixing tank 6, and the agglomerated material will be left on the top of the screen 83. The support cross bar 81 is vertically arranged on the first stirring shaft 711, and the fixed structure 84 connects the support cross bar 81 and the first stirring shaft 711 together by welding. A rolling component 82 is arranged on the outer surface of the support cross bar 81, and the rolling component 82 rolls and fits on the top of the screen 83. The rotation of the first stirring shaft 711 causes the support cross bar 81 to rotate at a uniform speed. Under the rotation of the support cross bar 81, the rolling component 82 rolls on the surface of the screen 83, and the agglomerated material on its surface is crushed and broken, so that the agglomerated material can pass through the screen 83 again and fall into the mixing tank 6.
