DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] Please refer to the picture 1The embodiment of the utility model provides a portable oak barrel stirring device, which is used to extend into the oak barrel to stir the wine brewed in the oak barrel. The portable oak barrel stirring device includes a handheld frame 1, a drive motor 2, a stirring shaft 3 and a protective cover 4. The drive motor 2 is arranged on the handheld frame 1, and the stirring shaft 3 is vertically arranged at the lower end of the handheld frame 1 and is connected to the output shaft of the drive motor 2. A stirring blade 5 for stirring the wine is arranged at the lower end of the stirring shaft 3. The protective cover 4 is sleeved on the stirring shaft 3 and is close to one end of the handheld frame 1, and is relatively free to rotate with the stirring shaft 3. When stirring the wine in the oak barrel, after opening the inspection port at the upper end of the oak barrel, the end of the stirring shaft 3 provided with the stirring blade 5 is inserted from the upper end of the oak barrel. The inspection port of the oak barrel is extended into the oak barrel, and the protective sleeve 4 is blocked at the inspection port of the oak barrel. The protective sleeve 4 is made of rubber or silicone material, matched with the inspection port of the oak barrel, and is in airtight contact with the outer wall of the stirring shaft 3. The wine will not overflow from between the stirring shaft 3 and the protective sleeve 4. The driving motor 2 is an electric motor, powered by an external power supply or a mobile power supply, to drive the stirring shaft 3 to drive the stirring blade 5 to rotate and stir in the oak barrel. During the stirring process, the protective sleeve 4 is always blocked at the inspection port of the oak barrel, and the inspection port of the oak barrel is sealed, which can prevent the wine from overflowing from the inspection port, thereby avoiding the loss of the wine and the pollution of the outside of the oak barrel caused by the overflow of the wine. In addition, during the stirring process, the contact between the external air and the wine can be reduced, thereby slowing down the oxidation rate of the wine.

[0024] Specifically, the protective sleeve 4 is an inverted cone structure, the diameter of the end of the protective sleeve 4 facing the stirring blade 5 is smaller than the inspection port of the oak barrel, and the diameter of the other end of the protective sleeve 4 is larger than the inspection port of the oak barrel. When stirring, the stirring blade 5 is inserted into the inspection port of the oak barrel, and the handheld frame 1 is pressed by hand so that the end of the protective sleeve 4 facing the stirring blade 5 can be inserted into the inspection port of the oak barrel. After the inspection port is blocked, the driving motor 2 is turned on to drive the stirring shaft 3 for stirring. The protective sleeve 4 is made of rubber or silicone material, has a certain elasticity, and plays a protective role on the inspection port of the oak barrel. When the stirring shaft 3 is shaken left and right in the oak barrel for stirring, the protective sleeve 4 can also play a good airtightness and prevent the wine from overflowing from the inspection port. In addition, the protective sleeve 4 also has a shock-absorbing effect to prevent the vibration force of the stirring shaft 3 during operation from acting on the oak barrel.

[0025] Please continue to refer to the picture 1Furthermore, a buffer spring 6 is sandwiched between the handheld frame 1 and the protective cover 4. The buffer spring 6 is a compression spring, which is sleeved on the stirring shaft 3. One end of the buffer spring 6 is fixedly connected to the lower end of the handheld frame 1, and the other end is fixedly connected to the protective cover 4. The protective cover 4 can slide freely along the stirring shaft 3. During the stirring process, the buffer spring 6 can play a buffering role, so that the handheld frame 1 can adaptively move up and down, and form a downward force on the protective cover 4, pressing the protective cover 4 tightly against the inspection port of the oak barrel, and avoiding hard contact between the handheld frame 1 and the oak barrel.

[0026] Furthermore, the handheld frame 1 is made of a stainless steel box body that is sealed on all sides, the drive motor 2 is arranged in the sealed box body, and a through hole is opened at the lower end of the box body for the stirring shaft 3 to penetrate, the stirring shaft 3 penetrates into the box body along the through hole and is connected with the output shaft of the drive motor 2, and a sealing sleeve 7 is arranged on the through hole, the sealing sleeve 7 is sealed on the stirring shaft 3, and is sealed with the lower end of the box body, and the sealing sleeve 7 and the stirring shaft 3 can rotate relative to each other, and the drive motor 2 and the connection with the stirring shaft 3 are sealed by the sealed box body and the sealing sleeve 7, which can prevent dust or other foreign matter generated at the connection between the drive motor 2 and the stirring shaft 3 from falling into the oak barrel and causing pollution to the wine.

[0027] Please continue to refer to the picture 1 For the convenience of operation, a first handle 8 is fixedly provided on one side of the handheld frame 1, and a second handle 9 is fixedly provided on the top of the handheld frame 1. When in use, the worker holds the first handle 8 and the second handle 9 with both hands to perform stirring operations. During the stirring process, the worker can push and pull the second handle 9 to tilt the handheld frame 1 to both sides of the oak barrel to change the stirring direction of the stirring shaft 3. The second handle 9 is mainly provided to facilitate the worker to apply force and adjust the stirring direction, so as to improve the stirring efficiency.

[0028] For ease of use, a battery 14 may be provided in the sealed box, and the battery 14 is electrically connected to the drive motor 2 through a wire to provide power for the drive motor 2. A speed regulating switch is provided on the first handle 8, and the speed regulating switch is electrically connected to the control end of the drive motor 2 through a wire, and the speed of the drive motor 2 is controlled by the speed regulating switch.

[0029] Please refer to the picture 2Furthermore, since oak barrels are generally stored in multiple layers on oak barrel racks, the height space between two layers of oak barrels is limited and the space is small. If the stirring shaft 3 is too long, it will not be able to be smoothly inserted into the oak barrel. If the stirring shaft 3 is too short, it cannot be inserted into the bottom of the barrel, which will affect the stirring effect. To address this problem, in a preferred embodiment, the device adopts a secondary shaft 10 at the lower end of the stirring shaft 3. The secondary shaft 10 is coaxially sleeved and connected with the stirring shaft 3. The stirring blade 5 is arranged at the lower end of the secondary shaft 10. The secondary shaft 10 can be freely extended and retracted along the stirring shaft 3, and can rotate synchronously with the stirring shaft 3 to increase or decrease the total length of the shaft, so as to facilitate the use of the stirring shaft 3 in a narrow space. Furthermore, a through groove 11 communicating with the inner cavity of the stirring shaft 3 is opened on the outer wall of the stirring shaft 3 along its length direction, and the sub-shaft 10 is sleeved on the outer wall of one end of the stirring shaft 3 and is provided with a pin 12 capable of passing through the through groove 11. When the sub-shaft 10 is freely extended and retracted along the stirring shaft 3, the pin 12 follows the sub-shaft 10 and moves freely along the through groove 11. The pin 12 is used to limit the sub-shaft 10 to prevent the sub-shaft 10 from being separated from the stirring shaft 3. Moreover, the pin 12 facilitates the contraction or extension of the sub-shaft 10. Specifically, when stirring an oak barrel with insufficient height space, the sub-shaft 10 can be manually retracted into the stirring shaft 3 to shorten the shaft length. After the stirring blade 5 is inserted into the oak barrel, the pin 12 is manually pushed toward the stirring blade 5 to extend the sub-shaft 10 out of the stirring shaft 3 to increase the shaft length. When the stirring is completed, the handheld frame 1 is lifted up to expose the pin 12 from the oak barrel, and then the pin 12 is manually pushed to move toward the handheld frame 1 to retract the secondary shaft 10 into the stirring shaft 3 again.

[0030] Please see Figure 3 and Figure 4In view of the technical problem that the height space between the two layers of oak barrels is limited and the space is narrow, which affects the insertion of the stirring shaft 3, in another preferred embodiment, the device adopts a sub-shaft 10 vertically arranged at the lower end of the stirring shaft 3, and the upper end of the sub-shaft 10 is connected to the stirring shaft 3 through a bendable elastic member 13, and the stirring blade 5 is arranged at the lower end of the sub-shaft 10, and the elastic member 13 is a rubber rod or a spring. When the sub-shaft 10 is squeezed by an external force, it can be bent to any side of the stirring shaft 3 through the elastic member 13 to reduce the total height of the shaft, so as to facilitate the stirring operation in a narrow space. Specifically, when performing the stirring operation, the sub-shaft 10 can be manually adjusted to be 60- 90° bending, the elastic member 13 is bent and deformed under the action of the bending of the secondary shaft 10. After the secondary shaft 10 with the stirring blade 5 is inserted into the oak barrel, the secondary shaft 10 is released, and the stirring shaft 3 is inserted into the oak barrel in turn. At this time, the elastic member 13 can be deformed and restored to a straight state without being affected by external forces, so that the secondary shaft 10 and the stirring shaft 3 are parallel again. When the stirring is completed, the handheld frame 1 is lifted up to expose the elastic member 13 out of the oak barrel, and the handheld frame 1 is tilted to one side and continuously pulled outward. The secondary shaft 10 is squeezed by the inspection port wall of the oak barrel to make the elastic member 13 bend adaptively. After manually grasping the secondary shaft 10, auxiliary bending is performed and it is taken out.

[0031] The stirring device can effectively stir oak barrels with narrow external space through the above two embodiments, and has high flexibility and strong practicality.

[0032] In the above embodiment, the stirring blade 5 is a flexible elastic blade made of stainless steel sheet, plastic or rubber and the like. The stirring blade 5 can bend adaptively when entering and exiting the inspection port of the oak barrel and is not blocked by the inspection port of the oak barrel, making the operation more convenient and quick.

[0033] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
