[0022] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0023] Embodiment 1

[0024] like Figure 1 As shown, a lifting stirring mechanism provided by an embodiment of the utility model comprises a stirring driving shaft 1, a stirring driven shaft 2 and a lifting unit, wherein the stirring driven shaft is connected to a stirring rod, and the stirring rod is a prior art, so it will not be described in detail here;

[0025] The stirring drive shaft is connected to the driving unit, which may be a servo motor. In order to achieve that the stirring driven shaft can maintain a transmission connection with the stirring drive shaft during the movement along its own height direction, the stirring drive shaft of this embodiment has a transmission part 3, the cross section of which is a polygon. In this embodiment, a hexagon is used as an example, and a slot matching the transmission part is provided on the stirring driven shaft.

[0026] The lifting unit is used to drive the stirring driven shaft to move up and down, and includes a screw rod 4, a slider 5 and a frame 6. The slider is mounted on the screw rod. A rotating sleeve 7 is sleeved on the stirring driven shaft. The rotating sleeve is connected to the slider 5 through a connecting rod. When the screw rod rotates, the stirring driven shaft will be driven to move up and down without affecting the rotation of the stirring driven shaft.

[0027] In order to better combine the lifting unit and the stirring mechanism, the screw drive shaft and the stirring drive shaft of this embodiment are connected through a transmission component, and the transmission component of this embodiment is a belt transmission structure.

[0028] Embodiment 2

[0029] like Figure 2 As shown, this embodiment provides a lifting stirring mechanism, including a stirring driving shaft 1, a stirring driven shaft 2 and a lifting unit, wherein the stirring driven shaft is connected to a stirring rod, and the stirring rod is a prior art, so it will not be described in detail here;

[0030] The stirring drive shaft is connected to the driving unit, which may be a servo motor. In order to achieve that the stirring driven shaft can maintain a transmission connection with the stirring drive shaft during the movement along its own height direction, the stirring drive shaft of this embodiment has a transmission part 3, the cross section of which is a polygon, and a slot matching the transmission part is provided on the stirring driven shaft;

[0031] The lifting unit is used to drive the stirring driven shaft to move up and down, and includes a screw rod 4, a slider 5 and a frame 6. The slider is mounted on the screw rod. A rotating sleeve 7 is sleeved on the stirring driven shaft. The rotating sleeve is connected to the slider through a connecting rod. When the screw rod rotates, the stirring driven shaft will be driven to move up and down without affecting the rotation of the stirring driven shaft.

[0032] In order to better combine the lifting unit and the stirring mechanism, the screw drive shaft and the stirring drive shaft of this embodiment are connected by a transmission assembly, and the transmission assembly of this embodiment is a first gear 9 and a second gear 10 respectively installed on the stirring drive shaft and the screw drive shaft; the first gear is fixedly arranged on the stirring drive shaft;

[0033] In order to allow the stirring rod (not shown) to stir at a certain height, the transmission assembly of this embodiment can temporarily disconnect the transmission between the stirring drive shaft and the screw drive shaft. Specifically:

[0034] A keyway is provided on the screw drive shaft, and a key matching the keyway is installed on the inner ring of the second gear, so that the second gear and the screw drive shaft rotate synchronously. The screw drive shaft is also sleeved with a spring 11, which is connected to the screw drive shaft;

[0035] When the stirring rod needs to stay at a certain height, the second gear can be separated from the first gear by inserting a fork 8 into the lower side of the second gear and pulling the fork upwards. When it is necessary to return to the stirring and lifting mode at the same time, release the fork, and the second gear will move downward under its own gravity and the action of the spring to engage with the first gear. It should be noted that when the second gear is engaged with the first gear, the spring is separated from the second gear to avoid friction between the two.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit and basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numerals in the claims should not be regarded as limiting the claims involved.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
