DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-7 As shown, a reaction stirring device comprises a shell 1, the top of the shell 1 is fixedly connected to the bottom of the motor 2, the top of the shell 1 is provided with an adjusting mechanism 3, the adjusting mechanism 3 comprises a fixed block 4, the top of the fixed block 4 is slidably connected to the lifting block 5, the inner side of the lifting block 5 is rotatably connected to the upper gear 6, the bottom of the shell 1 is fixedly connected to the discharge port 7, the bottom of the upper gear 6 is fixedly connected to the rotating shaft 8, the bottom of the rotating shaft 8 is fixedly connected to the stirring rod 9, the top and bottom of the fixed block 4 are both rotatably connected to a worm 12, one end of the worm 12 is meshedly connected to the top of a worm wheel 13, the rear part of the worm wheel 13 is fixedly connected to a driving wheel 14, the outer side of the driving wheel 14 is rotatably connected to the inner wall of the fixed block 4, one side of the driving wheel 14 is meshedly connected to a driven wheel 15, the outer side of the driven wheel 15 is rotatably connected to the inside of the fixed block 4, and one side of the fixed block 4 is fixedly connected to two oil tanks 16.

[0025] In this embodiment, the bottom of the fixed block 4 is also slidably connected to the lifting block 5, the inner side of the lifting block 5 is rotatably connected to the lower gear 17, the bottom of the lower gear 17 is fixedly connected to the sleeve 10, and the bottom of the sleeve 10 is fixedly connected to the impeller 11.

[0026] The motor 2 can drive the lower gear 17 and the shaft sleeve 10 to rotate, thereby driving the impeller 11 to rotate and stirring the raw materials in the housing 1.

[0027] In this embodiment, a circular hole is opened on the top of the sleeve 10 and passes through to the bottom, and the diameter of the circular hole matches the diameter of the rotating shaft 8 .

[0028] The bottom of the rotating shaft 8 passes through the shaft sleeve 10 and is connected to the stirring rod 9, thereby driving the stirring rod 9 to rotate.

[0029] In this embodiment, a bevel gear-shaped protrusion is provided at the rear of the motor 2, and a circular hole is opened at the front of the fixing block 4 and penetrates to the rear.

[0030] The motor 2 meshes with the upper gear 6 and the lower gear 17 through the bevel gear-shaped protrusion, and drives the upper gear 6 and the lower gear 17 to rotate in different directions.

[0031] In this embodiment, two circular holes and one T-shaped hole are formed on the top and bottom of the fixing block 4 , and two cylindrical protrusions and one piston-shaped protrusion are formed on the bottom of the lifting block 5 .

[0032] The two cylindrical protrusions and one piston-shaped protrusion of the lifting block 5 can slide in the hole of the fixed block 4 and restrict the movement of the lifting block 5.

[0033] In this embodiment, two cavities are formed inside the fixing block 4 , and the shapes of the cavities match the worm 12 and the worm wheel 13 .

[0034] The cavity of the fixed block 4 can accommodate the movement of the worm 12 and the worm wheel 13 inside, and the worm 12 and the worm wheel 13 can only rotate in the original position. The oil tank 16 is filled with hydraulic oil. When the worm wheel 13 drives the driving wheel 14 and the driven wheel 15 to rotate, the hydraulic oil can be extracted from the T-shaped hole of the fixed block 4, or the hydraulic oil can be squeezed into the T-shaped hole, thereby controlling the rise or fall of the lifting block 5.

[0035] In this embodiment, the tops of the two lifting blocks 5 are both provided with through circular holes. The diameter of the circular hole of the lifting block 5 above the fixed block 4 matches the diameter of the rotating shaft 8 , and the diameter of the circular hole of the lifting block 5 below the fixed block 4 matches the diameter of the sleeve 10 .

[0036] The two lifting blocks 5 can respectively constrain the upper gear 6 and the lower gear 17 so that the upper gear 6 and the lower gear 17 can only move in a specific manner.

[0037] It should be noted that the utility model is a reaction stirring device, which has different stirring modes when in use, and can realize the function of simply and quickly switching between different stirring modes. The specific implementation method is to rotate the worm 12 on the top of the fixed block 4, so that the worm 12 drives the connected worm wheel 13 to rotate. When the worm wheel 13 rotates, it will drive the driving wheel 14 to rotate together. When the driving wheel 14 rotates, it drives the driven wheel 15 connected thereto to rotate;

[0038] When the driving wheel 14 and the driven wheel 15 mesh with each other and rotate, the hydraulic oil in the oil tank 16 is pumped out, and the hydraulic oil enters the T-shaped hole at the top of the fixed block 4. After the hydraulic oil enters the T-shaped hole, the pressure in the hole will increase, thereby pushing the top lifting block 5 to rise. When the lifting block 5 rises, it drives the upper gear 6 to move synchronously. The upper gear 6 drives the rotating shaft 8 and the stirring rod 9 to move together. After the upper gear 6 moves up a certain distance, it will release the meshing with the bevel gear-shaped protrusion of the motor 2, so that the stirring rod 9 loses the power to rotate;

[0039] Rotate the worm 12 in the opposite direction, the driving wheel 14 and the driven wheel 15 will pump out the hydraulic oil in the T hole on the top of the fixed block 4, so that the lifting block 5 on the top will drop, and drive the upper gear 6 to drop together. When the upper gear 6 drops a certain distance, it will mesh with the bevel gear-shaped protrusion of the motor 2. When the motor 2 rotates, it will drive the upper gear 6 and the rotating shaft 8 to rotate together, and the rotating shaft 8 will drive the stirring rod 9 to rotate, thereby stirring the raw materials;

[0040] By rotating the worm 12 at the bottom of the fixed block 4 in different directions, the lifting block 5 at the bottom of the fixed block 4 can be controlled to rise and fall. When the bottom lifting block 5 moves, it will drive the lower gear 17 to move together. When the lower gear 17 moves, it will drive the shaft sleeve 10 to move. The shaft sleeve 10 drives the impeller 11 to move synchronously. When the lower gear 17 moves down a certain distance, it will release the meshing with the bevel gear-shaped protrusion of the motor 2, so that the impeller 11 loses the power to rotate. By moving the lifting block 5 upward, the lower gear 17 is meshed with the bevel gear-shaped protrusion of the motor 2. When the motor 2 rotates, it will drive the lower gear 17 to rotate. The lower gear 17 drives the shaft sleeve 10 to rotate, and the shaft sleeve 10 drives the impeller 11 to rotate, thereby stirring the raw materials;

[0041] When only the upper gear 6 is meshed with the motor 2, the motor 2 will only drive the stirring rod 9 to rotate; when only the lower gear 17 is meshed with the motor 2, the motor 2 will only drive the impeller 11 to rotate; when both the upper gear 6 and the lower gear 17 are meshed with the motor 2, the motor 2 will drive the impeller 11 and the stirring rod 9 to rotate at the same time, and the impeller 11 and the stirring rod 9 will rotate in opposite directions;

[0042] By setting the adjustment mechanism 3, the reaction stirring device has a variety of stirring modes, so that it can adapt to different usage requirements, increase the applicability of the device, and can quickly switch between different stirring modes without the need to disassemble and replace parts, thereby improving work efficiency.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
