DETAILED DESCRIPTION

[0031] Example:

[0032] like Figure 1-Figure 7As shown, an embodiment of the utility model provides a double-shaft multi-tooth rake stirring mixer, comprising a mixing box 1, supporting legs 2 are fixedly arranged at the four corners of the bottom of the mixing box 1, an upper cover 3 is rotatably arranged on the inner side of the upper surface of the mixing box 1 through a hinge, a feed port 4 is opened in the center of the upper surface of the upper cover 3, a motor 5 is fixedly arranged on the right side surface of the mixing box 1, a first transmission shaft 6 is fixedly arranged on the output end of the motor 5, a driving gear 7 is fixedly arranged on the left end of the first transmission shaft 6, a driven gear 8 is meshed on the driving gear 7, a second transmission shaft 9 is fixedly arranged on the driven gear 8, and the first transmission shaft 6 and the second transmission shaft 9 are both rotatably arranged on the mixing box 1 through bearings, a plurality of rake agitators are fixedly arranged on the outer sides of the first transmission shaft 6 and the second transmission shaft 9, and a discharge valve pipe 11 is penetrated through the bottom of the mixing box 1.

[0033] By providing a motor 5, a first transmission shaft 6, a driving gear 7, a driven gear 8, and a second transmission shaft 9, when mixing materials, the motor 5 drives the first transmission shaft 6 to rotate, the first transmission shaft 6 drives the driving gear 7 to rotate, the driving gear 7 drives the driven gear 8 and the second transmission shaft 9 to rotate, so that multiple rake agitators on the first transmission shaft 6 and the second transmission shaft 9 rotate, achieving the effect of mixing materials, a single motor can drive two transmission shafts to rotate, and more energy saving;

[0034] The first transmission shaft 6 drives the second transmission shaft 9 to rotate by meshing with the driven gear 8 through the driving gear 7, so that the rotation directions of the first transmission shaft 6 and the second transmission shaft 9 are opposite, ensuring that the rake agitator on the first transmission shaft 6 and the rake agitator on the second transmission shaft 9 drive the materials to move in opposite directions. When the motor 5 rotates clockwise, it drives the first transmission shaft 6 and the rake agitator on the first transmission shaft 6 to rotate clockwise, and drives the driven gear 8 to rotate counterclockwise through the driving gear 7, so that the second transmission shaft 9 and the rake agitator on the second transmission shaft 9 rotate counterclockwise, and the first transmission shaft 6 and the second transmission shaft 6 rotate counterclockwise. The rake agitator on the driving shaft 9 moves the materials on both sides of the mixing box 1 toward the center to ensure that the materials are in the center of the mixing box 1. Conversely, when the motor 5 rotates counterclockwise, the rake agitator on the first transmission shaft 6 rotates counterclockwise, and the rake agitator on the second transmission shaft 9 rotates clockwise. The rake agitators on the first transmission shaft 6 and the second transmission shaft 9 move the materials on both sides of the mixing box 1 toward both sides of the mixing box 1 to ensure that the materials are on both sides inside the mixing box 1, preventing the materials in the mixing box 1 from moving to one side of the mixing box 1 during mixing, thereby ensuring the stability of the mixing box 1 during mixing and ensuring the uniformity of the mixing.

[0035] By providing an upper cover 3, the upper cover 3 is rotatably arranged above the mixing box 1 through a hinge, so that the upper part can be opened conveniently, and the materials stuck on the rake stirrer can be cleaned conveniently, thereby ensuring the mixing effect.

[0036] In this embodiment, the motor 5 is a forward and reverse rotating motor, and the motor 5 is electrically connected to an external power source through electric wires, so that the motor 5 can drive the first transmission shaft 6 to rotate clockwise or counterclockwise.

[0037] In this embodiment, the rake agitators on the first transmission shaft 6 and the second transmission shaft 9 are staggered, which increases the mixing efficiency and ensures the mixing effect.

[0038] In this embodiment, the rake agitator includes a fixed sleeve 10, a connecting rod 1001 and a rake body 1002. The fixed sleeve 10 is fixedly welded to the first transmission shaft 6 and the second transmission shaft 9. The connecting rod 1001 is fixedly arranged on both the inner and outer sides of the fixed sleeve 10. The end of the connecting rod 1001 is detachably connected to the rake body 1002.

The rake body 1002 includes an embedding plate 1005, a positioning column 1006, a mounting groove 1007 and a spring 1008. The embedding plate 1005 is fixedly set at the center of the end of the rake body 1002, and the mounting groove 1007 is opened on the upper surface of the embedding plate 1005. The positioning column 1006 is fixedly set at the inner bottom of the mounting groove 1007 through a spring 1008.

[0040] In this embodiment, the embedded plate 1005 matches the embedded groove 1003 , the positioning column 1006 matches the positioning hole 1004 , and when the embedded plate 1005 is completely embedded in the embedded groove 1003 , the positioning column 1006 is embedded in the positioning hole 1004 .

[0041] In this embodiment, when the spring 1008 is in a naturally extended state, the upper part of the positioning column 1006 extends out of the installation slot 1007, and the distance that the positioning column 1006 extends out of the installation slot 1007 is equal to the depth of the positioning hole 1004, so that the positioning column 1006 can fill the positioning hole 1004 when embedded in the positioning hole 1004, thereby preventing materials from being embedded in the positioning hole 1004.

[0042] In this embodiment, when the spring 1008 is in the maximum compression state, the positioning column 1006 is completely embedded in the installation groove 1007, so that the positioning column 1006 can contact and position the embedded plate 1005 easily.

[0043] The rake body 1002 of the rake type agitator is detachably connected to the connecting rod 1001, so that when the rake body 1002 of the rake type agitator is damaged, it is convenient to take out the rake body 1002 for repair or replacement. When taking out the rake body, the positioning column 1006 is pressed downward so that the positioning column 1006 is completely embedded in the installation groove 1007, and the rake body 1002 is pulled away from the connecting rod 1001, and the embedding plate 1005 on the rake body 1002 is removed from the embedding groove 1007. 3, the rake body 1002 can be taken out from the connecting rod 1001, which is convenient for repair or replacement of the rake body 1002. When installing the rake body, the positioning column 1006 is pressed into the installation groove 1007, and the embedded plate 1005 is inserted into the embedded groove 1003.

[0044] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
