[0039] The present application provides a wine drawing device for oak barrels, which is used to draw wine liquid in an oak barrel.

[0040] Among them, according to the wine volume, flavor and other needs of wine making, the oak barrels used have multiple specifications, and the multiple specifications of the oak barrels have differences in at least one of, for example, capacity, height, barrel wall thickness, etc.

[0041] The specific embodiments of the wine drawing device for oak barrels of the present application will be described in detail below with reference to the accompanying drawings.

[0042] Figure 1A structure diagram of a wine extracting device for oak barrels in the present example.

[0043] Reference Figure 1 The wine extracting device for oak barrels includes a fixing frame 1, a wine extracting pipe 2, and a lifting frame 3. The fixing frame 1 is internally formed with a wine extracting space for placing the oak barrel. The wine extracting pipe 2 is arranged on the fixing frame 1 and at least partially located in the wine extracting space. The wine extracting pipe 2 is used for inserting into the oak barrel from the barrel mouth and for the communication between the inside and outside of the oak barrel. The lifting frame 3 is arranged on the fixing frame 1 in a lifting manner and located in the wine extracting space. The lifting frame 3 is connected with the wine extracting pipe 2 and can drive the wine extracting pipe 2 to lift relative to the fixing frame 1 to adjust the height position of the wine extracting pipe 2.

[0044] In the present application, the lifting frame 3 arranged on the fixing frame 1 in a lifting manner is used to drive the wine extracting pipe 2 to lift to adjust the height position of the wine extracting pipe 2, so as to adjust the distance between the bottom pipe mouth of the wine extracting pipe 2 and the bottom wall in the oak barrel, and then facilitate the extraction of the wine in the oak barrel as much as possible, greatly reduce the residual wine level in the oak barrel, reduce the residual wine amount of a single barrel, and thus reduce the cost loss. Moreover, the height-adjustable design of the wine extracting pipe 2 also facilitates the adaptation to the wine extracting operation of the oak barrels with various capacities, heights, and barrel wall thicknesses, and improves the versatility of the wine extracting device for oak barrels. Meanwhile, the above design can also play an auxiliary role in the operation process of inserting or pulling out the liquid pipe section in or from the oak barrel, which can save manpower to a certain extent.

[0045] In the present embodiment, the fixing frame 1 is arranged on a support surface. The support surface can be the ground or the top surface of any other structure.

[0046] Exemplarily, the fixing frame 1 includes a top frame 11 and two side frames 12. Specifically, the two side frames 12 are vertically arranged on the support surface with a spacing, and the top frame 11 is fixed between the two side frames 12. The two side frames 12 and the top frame 11 enclose a wine extracting space with an internal hollow and two through ends, which is used for accommodating the oak barrel placed on the support surface.

[0047] Exemplarily, the top frame 11 includes two side beams and two end beams. The two side beams and the two end beams are connected in a head-to-tail manner to form a square frame. The top frame 11 can also include a plurality of connecting beams connected between the two side beams or the two end beams with a spacing. Optionally, a plurality of reinforcing beams can be connected between the adjacent two connecting beams to strengthen the structural strength of the top frame 11.

[0048] Each side frame 12 is fixed to the bottom of a side beam or the outer side. The side frame 12 can include two vertical columns vertically erected on the support surface and fixed to the lengthwise ends of the side beams, respectively. The side frame 12 can further include a plurality of intermediate beams vertically fixed between the two vertical columns to enhance the structural strength of the side frame 12.

[0049] The top frame 11 and the side frame 12 can also be other square frame structures, and the specific arrangement can be determined according to the needs, which is not limited herein.

[0050] The wine tapping pipe 2 is arranged on the fixing frame 1 and at least partially located in the tapping space for tapping the oak barrel from the barrel opening and for the communication between the inside and outside of the oak barrel. Specifically, one end of the wine tapping pipe 2 is located outside the fixing frame 1 for communication with the outside, such as a storage barrel, and the other end extends upward to the top frame 11 of the fixing frame 1 and extends along the top of the top frame 11, and then passes through the top frame 11 of the fixing frame 1 and extends downward into the tapping space for tapping the oak barrel from the barrel opening.

[0051] The number of wine tapping pipes 2 can be multiple, and the arrangement of each wine tapping pipe 2 is the same, and the portions of each wine tapping pipe 2 located in the tapping space are distributed at intervals, so that the oak barrel tapping device can simultaneously tap multiple oak barrels.

[0052] Reference Figure 1 Each wine tapping pipe 2 includes an extension pipe section 21 and a liquid guiding pipe section 22, and the extension pipe section 21 is in communication with the liquid guiding pipe section 22.

[0053] The extension pipe section 21 is arranged on the fixing frame 1 and at least partially extends into the fixing frame 1, and the inlet of the extension pipe section 21 is located in the tapping space. Specifically, one end of the extension pipe section 21 is located outside the fixing frame 1 for communication with the outside, such as a storage barrel, and the other end extends upward to the top frame 11 of the fixing frame 1 and extends along the top of the top frame 11, and then passes through the top frame 11 of the fixing frame 1 and extends downward into the tapping space so that the inlet is located in the tapping space.

[0054] The extension pipe section 21 is movably connected to the fixing frame 1. For example, the top of the fixing frame 1 is provided with a sliding member, and the extension pipe section 21 is arranged in the sliding member and movably connected to the sliding member, which can assist the movement of the extension pipe section 21 relative to the fixing frame 1.

[0055] In the embodiment, the sliding member comprises a pipe holder and a sliding base. The pipe holder is sleeved on the extension pipe section 21 and can move relative to the extension pipe section 21. The sliding base is fixed on the top of the fixed frame 1, and the sliding base is provided with a sliding groove with an open top. The pipe holder is at least partially limited and accommodated in the sliding groove and is in sliding cooperation with the sliding base. The sliding direction of the pipe holder relative to the sliding base is consistent with the moving direction of the extension pipe section 21 relative to the pipe holder. The above design enables the pipe holder to move in the same direction in the sliding groove during the movement of the extension pipe section 21 relative to the pipe holder, so that the vibration caused by the movement of the extension pipe section 21 relative to the pipe holder can be absorbed, thereby avoiding the direct transmission of the vibration to the fixed frame 1 and affecting the stability of the fixed frame 1. That is, the embodiment realizes the shockproof fixing of the extension pipe section 21 through the cooperation of the pipe holder and the sliding base, and can ensure the structural stability of the fixed frame 1 while realizing the movement of the extension pipe section 21 relative to the fixed frame 1.

[0056] In the embodiment, the pipe holder is provided with a through hole for the extension pipe section 21 to pass through. The pipe holder is provided with an inner liner in the through hole in the circumferential direction. The inner liner is fixed on the pipe holder and is used to abut against the outer periphery of the extension pipe section 21, so that the extension pipe section 21 moves relative to the pipe holder only under the action of an external force. During the movement, sliding friction is generated through the contact between the pipe holder and the extension pipe section 21, so as to increase the resistance of the extension pipe section 21, avoid uncontrollable factors caused by the rapid movement of the extension pipe section 21 under the action of the external force and its own gravity, and further ensure the stability and controllability of the movement of the extension pipe section 21. Moreover, the above design can also abut and fix the extension pipe section 21 in a static state, so as to ensure that the extension pipe section 21 in a static state will not move relative to the pipe holder under its own gravity. Specifically, the number of the inner liners is multiple, and the multiple inner liners are fixed on the inner circumferential wall of the pipe holder in the circumferential direction. The inner liner is in a Z shape.

[0057] The material of the inner liner is plastic, and the surface is relatively rough, which makes the inner liner have a large friction with the extension pipe section 21, so as to increase the resistance of the extension pipe section 21 during the movement or in the static state, and improve the stability of the extension pipe section 21.

[0058] In the embodiment, the length of the extension pipe section 21 is greater than the straight-line distance from the external wine storage barrel to the liquid guide pipe section 22, so as to leave a margin for the movement of the extension pipe section 21.

[0059] In the embodiment, the extension pipe section 21 is a flexible hose. That is, the extension pipe section 21 has flexibility, which enables the extension direction of the extension pipe section 21 to be easily adjusted according to needs during installation or use. Moreover, the above design enables the extension pipe section 21 to play a compensation role between the liquid guide pipe section 22 and other external pipelines or external wine storage barrels, etc., to absorb and relieve the displacement caused by thermal expansion and cold contraction, reduce vibration and impact, and improve the safety and reliability of the oak barrel wine extraction equipment.

[0060] In the embodiment, the liquid leading pipe section 22 is located in the liquid extracting space, and the outlet of the liquid leading pipe section 22 is communicated with the inlet of the extending pipe section 21. The liquid leading pipe section 22 is used to be inserted into the oak barrel. Specifically, the liquid leading pipe section 22 is fixedly connected with the extending pipe section 21 through the clamp 9 pipe bundle.

[0061] Figure 2 The structure diagram of the liquid leading pipe section 22 in the embodiment is shown.

[0062] Referring to Figure 1 and Figure 2 In the embodiment, the liquid leading pipe section 22 extends along a straight line, so as to control the extending direction of the liquid leading pipe section 22, and the liquid leading pipe section 22 is inserted into the oak barrel along the vertical direction, so as to control the interval distance between the bottom of the liquid leading pipe section 22 and the bottom wall in the oak barrel.

[0063] Optionally, the bottom of the pipe wall of the liquid leading pipe section 22 is provided with the aperture 221, which makes the wine in the oak barrel enter into the liquid leading pipe section 22 through the aperture 221 even if the bottom of the liquid leading pipe section 22 closely abuts on the bottom wall in the oak barrel, so as to ensure the normal liquid leading function of the liquid leading pipe section 22.

[0064] Specifically, the bottom of the liquid leading pipe section 22 is provided with a plurality of apertures 221 along the circumference, which makes the wine outside the circumference of the liquid leading pipe section 22 enter into the liquid leading pipe section 22 through any aperture 221 on the liquid leading pipe section 22, and the above design can also balance the pressure of the liquid leading pipe section 22 during the liquid leading, which is helpful to improve the liquid leading efficiency of the liquid leading pipe section 22 and to keep the liquid leading pipe section 22 unblocked. The shape of the aperture 221 can be any shape such as square, triangle, sector, etc., and the specific setting is determined according to the needs, which is not limited herein.

[0065] In other embodiments, the bottom of the liquid leading pipe section 22 can also be designed as a bevel, so as to make the cross section of the bottom of the liquid leading pipe section 22 be inclined from bottom to top, and to ensure that the bottom of the liquid leading pipe section 22 cannot completely abut on the bottom wall in the oak barrel. The bottom of the liquid leading pipe section 22 can also be other structures, which can be designed according to the actual needs, which is not limited herein.

[0066] In the embodiment, the liquid leading pipe section 22 is made of steel material, so as to make the liquid leading pipe section 22 have greater hardness, so as to ensure that the liquid leading pipe section 22 is not easy to deform, and to keep the state of extending along a straight line. In addition, the liquid leading pipe made of steel material has better corrosion resistance and durability, etc. Exemplarily, the liquid leading pipe section 22 can be made of stainless steel material.

[0067] In the embodiment, the length of the liquid leading pipe section 22 can be designed according to the height of the oak barrel. Optionally, the length of the liquid leading pipe is greater than the oak barrel with the highest height, so as to make the liquid leading pipe section 22 can adapt to the wine extracting operation of the oak barrels with various heights, so as to improve the universality of the oak barrel wine extracting equipment.

[0068] The liquid inlet section 22 uses a DN40 (inner diameter 40mm) pipe.

[0069] In this embodiment, a sight glass 23 is provided between the inlet pipe section 22 and the extension pipe section 21. The inlet pipe section 22 is located above the oak barrel, allowing the operator to observe the wine extraction process through the sight glass 23. Specifically, the sight glass 23 is made of transparent material and forms a cylindrical structure with open ends, so that the sight glass 23 can connect the inlet pipe section 22 and the extension pipe section 21 and allow the wine to flow.

[0070] Optionally, a filter screen 4 is provided inside the liquid inlet pipe section 22. The filter screen 4 is used to filter sawdust in the wine to ensure that the sawdust in the oak barrel can be reused multiple times.

[0071] The filter screen 4 is located above the opening 221 to ensure that the wine entering the extension pipe section 21 from the liquid inlet pipe section 22 is all wine that has been filtered by the filter screen 4 to remove the sawdust, while ensuring that the wine entering the outside is free of sawdust.

[0072] Specifically, filter screen 4 uses a 4-mesh filter screen.

[0073] In this embodiment, a one-way control valve 5 is provided on the liquid inlet pipe section 22 so that the wine in the liquid inlet pipe section 22 can only flow from bottom to top to avoid backflow of the wine. This prevents the wine from flowing out from the bottom of the liquid inlet pipe section 22 during the transfer of oak barrels, thus avoiding waste of the wine.

[0074] Specifically, the one-way control valve 5 is located at the lower part of the liquid inlet pipe section 22. This results in a smaller gap between the one-way control valve 5 and the bottom of the liquid inlet pipe section 22, meaning the section of the liquid inlet pipe section 22 below the one-way control valve 5 is shorter. This makes the capacity of the liquid inlet pipe section 22 below the one-way control valve 5 extremely small. Before stopping the liquid inlet and pulling out the liquid inlet pipe section 22, the backflow of the liquid is extremely small or even negligible, thus ensuring that the liquid in the oak barrel can be completely extracted, greatly reducing the amount of residual liquid in the oak barrel. Furthermore, the above design also allows the liquid in the section of the liquid inlet pipe section 22 below the one-way control valve 5 to completely flow back before the liquid inlet pipe section 22 is completely pulled out of the oak barrel. This ensures that the liquid inlet pipe section 22 will not leak after it is completely pulled out, thus achieving the goal of not wasting liquid during the extraction of liquid from the oak barrel.

[0075] Furthermore, the one-way control valve 5 is located above the filter screen 4 to ensure that the wine passing through the one-way control valve 5 is all wine that has been filtered out of sawdust by the filter screen 4, so as to prevent sawdust from being unable to pass through the one-way control valve 5 in the reverse direction and accumulating and clogging inside the liquid inlet pipe section 22, thus ensuring the unobstructed flow of the liquid inlet pipe section 22 and ensuring that the wine input to the outside is free of sawdust.

[0076] Reference Figure 1 The lifting frame 3 is arranged on the fixed frame 1 in a liftable manner, and is located in the liquid pumping space. The lifting frame 3 is connected with the wine pumping pipe 2, and can drive the wine pumping pipe 2 to lift relative to the fixed frame 1, so as to adjust the height position of the wine pumping pipe 2, and adjust the distance between the bottom of the wine pumping pipe 2 and the bottom wall of the oak barrel, so as to facilitate the wine in the oak barrel to be pumped out as much as possible, so as to reduce the residual wine level in the oak barrel, reduce the residual wine amount of a single barrel, and reduce the cost loss. In addition, the height-adjustable design of the wine pumping pipe 2 also facilitates the adaptation to the wine pumping operation of oak barrels with various capacities, heights and barrel wall thicknesses, and improves the universality of the oak barrel wine pumping equipment. At the same time, the above design can also play an auxiliary role in the operation process of inserting or pulling out the liquid pipe section in or from the oak barrel, which can save manpower to a certain extent.

[0077] The lifting frame 3 can be any square frame structure, which is not limited here.

[0078] In the embodiment, the fixed frame 1 is provided with a driving member 6, the output shaft 61 of the driving member 6 is connected and fixed with the lifting frame 3, and the driving member 6 is used to drive the lifting frame 3 to lift, so that the automatic lifting of the lifting frame 3 can be realized, and manpower can be saved. Specifically, the driving member 6 is arranged on the top frame 11 in a state that the output shaft 61 faces downward, and the output shaft 61 of the driving member 6 is located in the liquid pumping space and is connected and fixed with the top of the lifting frame 3.

[0079] The driving member 6 is a pneumatic cylinder. Since the wine is a flammable and explosive substance, when the vapor of the wine is mixed with air, it is easy to cause fire and explosion in a certain concentration range when encountering fire or high temperature. Therefore, compared with the driving member 6 using electricity as power, the pneumatic cylinder using air pressure as power can avoid some tiny sparks in the process of using electricity to cause fire and explosion, so as to achieve the explosion-proof purpose of the area where the oak barrel wine pumping equipment is located, and ensure the safety of the wine pumping operation process.

[0080] Specifically, the extension pipe section 21 is fixedly connected with the lifting frame 3, so that the liquid guiding pipe section 22 is completely positioned below the lifting frame 3, thereby preventing the lifting frame 3 from interfering with the oak barrel, ensuring the depth of the liquid guiding pipe section 22 into the barrel, and enabling the liquid guiding pipe section 22 to approach the height of the barrel, so that the wine in barrels of various specifications can be drawn as much as possible, greatly reducing the residual wine in the barrel. For example, a fixing ring is fixed to the outer side of the lifting frame 3, the fixing ring is provided with a fixing hole, the extension pipe section 21 is arranged in the fixing hole and is clamped and fixed with the fixing ring, so as to prevent the extension pipe section 21 from sliding relative to the fixing ring under the action of its own gravity, and to ensure the stability of the wine drawing pipe 2. The axis of the fixing hole extends vertically, so as to facilitate the vertical extension of the liquid guiding pipe section 22. The extension pipe sections 21 of a plurality of wine drawing pipes 2 are fixed on the lifting frame 3 at intervals in the circumferential direction.

[0081] In the embodiment, the oak barrel wine drawing device comprises a detector 81 arranged on the output shaft 61 of the driving member 6, which is used to detect the height position information of the lifting frame 3, so that the operator can know the height position of the lifting frame 3, and thus know the height position of the liquid guiding pipe section 22 and the depth of the barrel.

[0082] The oak barrel wine drawing device can further comprise a first limit switch 82 and a second limit switch 83 arranged at intervals in the vertical direction. The first limit switch 82 is located above the second limit switch 83, and the first limit switch 82 and the second limit switch 83 are correspondingly arranged on the outer side of the output shaft 61 of the driving member 6, and the projections of the first limit switch 82 and the second limit switch 83 in the horizontal direction fall on the output shaft 61 in the fully extended state. The first limit switch 82 is used to detect the first high position information of the detector 81, and the second limit switch 83 is used to detect the first low position information of the detector 81. The first limit switch 82 and the second limit switch 83 are in communication connection with the driving member 6, and are respectively used to turn off the driving member 6.

[0083] Specifically, when the output shaft 61 of the driving member 6 moves upward to the height at which the detector 81 reaches the first limit switch 82 under the action of the driving member 6, the first limit switch 82 controls the driving member 6 to be turned off, so as to limit the output shaft 61 from continuing to move upward, so as to position the height position of the lifting frame 3 and the liquid guiding pipe section 22. Alternatively, when the output shaft 61 of the driving member 6 moves downward to the height at which the detector 81 reaches the second limit switch 83, the second limit switch 83 controls the driving member 6 to be turned off, so as to limit the output shaft 61 from continuing to move downward.

[0084] The wine extracting device for oak barrels can further comprise a third limit switch 84 and a fourth limit switch 85 vertically spaced apart on the output shaft 61 of the driving member 6, the third limit switch 84 is located above the fourth limit switch 85, and the third limit switch 84 and the fourth limit switch 85 are located between the first limit switch 82 and the second limit switch 83. Moreover, the third limit switch 84 and the fourth limit switch 85 are correspondingly arranged on the outer side of the output shaft 61 of the driving member 6, and the projections of the third limit switch 84 and the fourth limit switch 85 in the horizontal direction fall on the output shaft 61 in the fully extended state. The third limit switch 84 is used to detect the second high position information of the detector 81, and the fourth limit switch 85 is used to detect the second low position information of the detector 81. The third limit switch 84 and the fourth limit switch 85 are both in communication connection with the driving member 6 and are respectively used to turn off the driving member 6.

[0085] Specifically, when the output shaft 61 of the driving member 6 moves upward to the height at which the detector 81 reaches the third limit switch 84 under the action of the driving member 6, the third limit switch 84 controls the driving member 6 to be turned off to limit the continuous upward movement of the output shaft 61, so as to position the height position of the lifting frame 3 and the liquid guide pipe section 22. Alternatively, when the output shaft 61 of the driving member 6 moves downward to the height at which the detector 81 reaches the fourth limit switch 85, the fourth limit switch 85 controls the driving member 6 to be turned off to limit the continuous downward movement of the output shaft 61.

[0086] Among them, the first limit switch 82 and the second limit switch 83 constitute a first switch group to adapt to the wine extracting operation of one specification of oak barrels, and the third limit switch 84 and the fourth limit switch 85 constitute a second switch group to adapt to the wine extracting operation of another specification of oak barrels. In actual application, one of the first switch group and the second switch group is in an open state, and the other is in a closed state, so as to avoid the interference between the first limit switch 82 and the third limit switch 84 or the second limit switch 83 and the fourth limit switch 85, which can cause the liquid guide pipe section 22 to fail to be lowered to the position, thereby affecting the depth of the liquid guide pipe section 22 into the barrel, or fail to be raised to the position, thereby causing the bottom of the liquid guide pipe section 22 to be unable to be located above the oak barrel, or the liquid guide pipe section 22 has been lowered to the position where the bottom thereof is attached to the bottom wall in the oak barrel, and the driving member 6 is still in the open state and continues to drive the liquid guide pipe section 22 to be lowered to punch and damage the oak barrel. Based on this, the above design can better adapt to the wine extracting operation of different specifications of oak barrels.

[0087] Exemplarily, for the oak barrels of two specifications of 200L and 250L, the oak barrel of 200L has a smaller barrel wall thickness and a lower height. When the wine drawing operation of the oak barrel of 200L is performed, the second switch group is opened, and the first switch group is in the closed state, so that the third limit switch 84 controls the upper limit of the movement of the output shaft 61 of the driving member 6, and the bottom of the liquid guide pipe section 22 is located above the oak barrel, facilitating the insertion of the liquid guide pipe section 22 from the barrel opening of the oak barrel or the complete pulling out of the liquid guide pipe section 22 from the oak barrel; so that the fourth limit switch 85 controls the lower limit of the movement of the output shaft 61 of the driving member 6, and the bottom of the liquid guide pipe section 22 can be lowered to approach or adhere to the bottom wall in the oak barrel, so as to draw out the wine in the oak barrel as much as possible, while avoiding the damage of the oak barrel caused by the continuous downward movement of the liquid guide pipe section 22. Similarly, when the wine drawing operation of the oak barrel of 250L is performed, the first switch group is opened, and the second switch group is in the closed state, so that the first switch controls the upper limit of the movement of the output shaft 61 of the driving member 6, and the second switch controls the lower limit of the movement of the output shaft 61 of the driving member 6, so as to have the same effect as described above.

[0088] In other embodiments, the oak barrel wine drawing device can further include other at least one switch group to adapt to an oak barrel of a specification. That is, regarding the design of the switch group, it can be set according to the specification of the specific oak barrel, which is not limited herein.

[0089] In other embodiments, for the oak barrels of the same height, the same limit switch can be used to limit the upper limit of the height, and for the oak barrels of the same barrel wall thickness, the same limit switch can be used to limit the lower limit of the height, so as to reduce the use of limit switches, simplify the structure of the oak barrel wine drawing device, and save costs.

[0090] The oak barrel wine drawing device can further include a controller, which is in communication connection with the detector 81 and the driving member 6. The controller can control the opening and closing of the driving member 6 to adjust the height position of the lifting frame 3 according to the height position information, so as to facilitate the automation of the oak barrel wine drawing device and save labor.

[0091] The first limit switch 82, the second limit switch 83, the third limit switch 84 and the fourth limit switch 85 are proximity switches.

[0092] The controller can also be in communication connection with the first limit switch 82, the second limit switch 83, the third limit switch 84 and the fourth limit switch 85, and can control the opening and closing of the first limit switch 82 and the second limit switch 83, the third limit switch 84 and the fourth limit switch 85, respectively, so as to facilitate the automation of the oak barrel wine drawing device and save labor.

[0093] Exemplarily, the specification information of various oak barrels can be input in the controller, and the specification information of various oak barrels is associated with each switch group, so that each switch group can correspond to one specification of oak barrels. When the wine drawing operation of one specification of oak barrels is performed, the specification information of the oak barrels can be input on the controller, and then the controller can automatically control the opening and closing of the driving member 6, the opening and closing of each switch group, etc., so that the height of the liquid inlet pipe section 22 can be automatically adjusted, and the wine drawing operation of the oak barrels can be automatically realized, thereby improving the production efficiency.

[0094] The oak barrel wine drawing device can further include a limiting frame 7, which is arranged at the top of the fixed frame 1, and a containing space with an open bottom is formed on the limiting frame 7. The lifting frame 3 is contained in the containing space, and at this time, the limiting frame 7 plays a containing limiting role on the lifting frame 3 to limit the circumferential displacement of the lifting frame 3. In addition, the limiting frame 7 can also be used for the installation of the first limiting switch 82, the second limiting switch 83, the third limiting switch 84, and the fourth limiting switch 85, that is, the first limiting switch 82, the third limiting switch 84, the fourth limiting switch 85, and the second limiting switch 83 are arranged on the limiting frame 7 in sequence along the vertical direction.

[0095] In the embodiment, the outer periphery of the lifting frame 3 and the limiting frame 7 have a movable gap, so as to avoid the interference of the limiting frame 7 on the lifting and lowering of the lifting frame 3, and to ensure that the lifting frame 3 can normally and smoothly lift and lower under the driving of the driving member 6.

[0096] In other embodiments, the outer periphery of the lifting frame 3 and the limiting frame 7 are slidingly matched, so that the lifting frame 3 can lift and lower along the limiting frame 7, that is, the limiting frame 7 can guide the lifting and lowering of the lifting frame 3 while limiting the lifting frame 3, which can improve the stability of the lifting and lowering of the lifting frame 3.

[0097] Specifically, in the embodiment, the limiting frame 7 can be composed of four limiting beams 71, which are arranged in sequence along the circumferential direction of the square top frame 11 of the fixed frame 1, and each limiting beam 71 corresponds to the outside of one corner of the lifting frame 3, that is, each limiting beam 71 corresponds to one corner of the lifting frame 3, and the above design can realize the limiting of the lifting frame 3 through a simple structure, which is convenient to manufacture and has a good limiting effect. At this time, the first limiting switch 82, the third limiting switch 84, the fourth limiting switch 85, and the second limiting switch 83 are arranged in sequence along the vertical direction on one of the limiting beams 71.

[0098] The limiting beam 71 can be a square tube steel or a bent beam with an L-shaped cross section.

[0099] In other embodiments, the limiting frame 7 can also be a square frame or other structures. The wine extracting device for oak barrels also comprises a suction pump in communication with the extracting pipe 2 for providing power to realize the wine extracting operation.

[0100] Specifically, the suction pump is a pneumatic diaphragm pump which uses compressed air as a power source so as to achieve the explosion-proof purpose of the area where the wine extracting device for oak barrels is located, thereby ensuring the safety of the wine extracting operation. At this time, the filter screen 4 can also prevent wood chips from entering the suction pump, thereby achieving the purpose of protecting the diaphragm of the suction pump.

[0101] The wine extracting device for oak barrels can also comprise a conveying mechanism arranged on the support surface, at least part of the conveying mechanism being located in the liquid extracting space, and both ends of the conveying mechanism in the length direction thereof extending out of the liquid extracting space, the conveying mechanism being used for conveying and supporting the oak barrel. The length direction of the conveying mechanism is consistent with the through direction of the fixing frame 1. For example, the conveying mechanism can be a roller type or a belt type conveyor, etc., that is, the linear movement of the oak barrel is driven by the rotation of the roller or the movement of the belt, etc., so as to realize the automatic conveying of the oak barrel, thereby further improving the automation of the wine extracting device for oak barrels and saving manual labor.

[0102] For example, after the conveying mechanism conveys the oak barrel to below the liquid guiding pipe section 22 from the outer side of the fixing frame 1, the conveying mechanism is paused to make the oak barrel temporarily stay, so as to perform the wine extracting operation. After the wine extracting operation is completed, the conveying mechanism is restarted to continue conveying the oak barrel to the other outer side of the fixing frame 1. In this process, the limiting frame 7 can also avoid the situation that the oak barrel is moved to drive the liquid guiding pipe section 22 to move, and the lifting frame 3 and the output shaft 61 of the driving member 6 have a tendency to move, that is, the limiting frame 7 can limit the lifting frame 3 to keep the lifting frame 3 in a state of being stationary relative to the limiting frame 7, so that the lifting frame 3 does not exert a pulling force on the output shaft 61 of the driving member 6, the output shaft 61 of the driving member 6 also keeps in a state of being vertically extended and stationary, and the output shaft 61 of the driving member 6 is ensured not to be deformed due to external force, thereby ensuring that the driving member 6 can be normally used.

[0103] From the above technical solutions, the wine extracting device for oak barrels has at least the following advantages and positive effects:

[0104] In the application, the lifting frame is arranged on the fixing frame to drive the wine pumping pipe to lift or lower, so as to adjust the height position of the wine pumping pipe, adjust the distance between the bottom pipe opening of the wine pumping pipe and the bottom wall in the oak barrel, and then facilitate the pumping of the wine in the oak barrel as much as possible, greatly reduce the residual wine level in the oak barrel, reduce the residual wine amount of a single barrel, and thus reduce the cost loss. Moreover, the height-adjustable design of the wine pumping pipe facilitates the adaptation of the wine pumping operation to various capacity, height and barrel wall thickness of the oak barrel, and improves the universality of the oak barrel wine pumping equipment. Meanwhile, the above design can assist the operation of inserting or pulling out the liquid pipe section in or from the oak barrel, which can save manpower to a certain extent.

[0105] Further, the mutual cooperation between the detector, the driving member, the first limit switch and the second limit switch, or the mutual cooperation between the detector, the driving member, the third limit switch and the fourth limit switch can realize the automation of the oak barrel wine pumping equipment, adapt to the wine pumping operation of different specifications of the oak barrel, and improve the universality of the oak barrel wine pumping equipment.

Since the present application can be embodied in many different forms without departing from the spirit or essential characteristics thereof, it should be understood that the above-described embodiments are not limited to any of the aforementioned details, but are to be construed broadly within the spirit and scope of the appended claims, and all changes and modifications that come within the meaning and range of equivalents are intended to be embraced by the claims.
