Description

Technical Field

[0001] This invention relates to the field of liquor technology, and in particular to a liquor sampling component for liquor tanks. Background Technology

[0002] After production, unpackaged baijiu needs to be stored in tanks. These tanks are generally sealed to slow down the evaporation of the baijiu and prevent it from deteriorating due to exposure to air. Before the baijiu is packaged, samples need to be taken from the tanks to determine if it has spoiled.

[0003] The invention patent CN 112213156 B discloses a baijiu (Chinese liquor) sampling component for baijiu tanks, relating to the field of baijiu. It includes a tank body and a cap, with a perforation at the top of the cap; a sampling column with an inner cavity, the side surface of which has an opening, the edge of which is fixed to the inner wall of the tank body; several partitions fixed within the inner cavity, dividing it into opposing sampling chambers, each with an inner hole on its inner wall; an adjusting rod slidably connected to the outer surface of the sampling column, the top of which extends through the perforation to the outside of the cap; the adjusting rod has an outer hole corresponding to the inner hole; when the inner hole is aligned with the corresponding outer hole, baijiu from the tank enters the sampling chamber; when the inner hole and the corresponding outer hole are misaligned, the sampling chamber is isolated from the environment inside the tank; the outer side of the tank body has an outlet corresponding to the sampling chamber and a matching sealing plug. This device ensures that the cap is not opened during sampling, guaranteeing the tank remains sealed during the sampling period.

[0004] After practical research by those skilled in the art, the above-mentioned device still has some drawbacks. The most obvious one is that when sampling the wine, air inside the sampling chamber can enter the tank through the inner and outer holes, resulting in excessive air inside the tank and easy contamination of the wine. In addition, because the wine inside the tank is not uniform, the above-mentioned device needs to sample wine at different heights separately in order to ensure the sampling effect. This is inconvenient to operate and requires repeated testing of the sampled wine multiple times, which increases the difficulty of testing.

[0005] Therefore, it is necessary to invent a liquor sampling component for liquor tanks to solve the above problems. Summary of the Invention

The lifting piston is slidably installed inside the sampling cylinder. Two piston rods and two first springs are provided. The two piston rods are slidably installed through the top two sides of the sampling cylinder and are fixedly connected to the lifting piston. The two first springs are respectively sleeved on the outside of the two piston rods. The annular sleeve is slidably sleeved on the outside of the reciprocating screw and fixedly connected to the two piston rods. The annular rotating plate is rotatably sleeved on the outside of the annular sleeve through a bearing.

[0012] Preferably, the venting and liquid discharge mechanism includes a first limiting ring, a discharge plate, a T-shaped rod, a fixed support rod, a receiving groove, a first sliding groove, a second spring, a one-way discharge pipe, and a telescopic discharge pipe.

[0013] Preferably, the first limiting ring is fixedly disposed at the bottom of the inner side of the sampling cylinder, the drain plate is slidably disposed inside the sampling cylinder and located at the top of the first limiting ring, the T-shaped rod is located inside the drain plate, multiple fixed support rods are provided, the multiple fixed support rods are evenly fixedly disposed outside the T-shaped rod and are all fixedly connected to the inner wall of the drain plate, the receiving groove is opened inside the reciprocating screw, the first sliding groove is opened through the front of the reciprocating screw, the T-shaped rod is slidably disposed inside the first sliding groove, the second spring is located inside the receiving groove, one end of the second spring is attached to the top of the T-shaped rod and the other end is attached to the inner wall of the receiving groove, the one-way drain pipe is fixedly disposed at the center of the bottom of the drain plate, and one-way valves are provided on both the one-way drain pipe and the one-way inlet pipe, the telescopic outlet pipe is fixedly nested at the bottom of the tank and connected to the one-way drain pipe through a rotary joint.

[0014] Preferably, the wine mixing mechanism includes a screw, a driven gear, a second slide groove, a sliding column, a sliding sleeve, a mixing rod, a third spring, and a second limiting ring.

[0015] Preferably, the top end of the screw is rotatably nested at the bottom of the base via a bearing. The screw passes through the lifting pressure plate and is slidably connected to it. The driven gear is fixedly sleeved on the top outer side of the screw and meshes with the driving gear. The second sliding groove is opened through the front of the screw. Multiple sliding columns, sliding sleeves, mixing rods, and third springs are provided. Multiple sliding columns are evenly slidably disposed inside the second sliding groove. Multiple sliding sleeves are evenly sleeved on the outside of the screw and fixedly connected to multiple sliding columns respectively. Multiple mixing rods are evenly fixedly disposed on both sides of multiple sliding sleeves. Multiple mixing rods are evenly sleeved on the outside of the screw. Any one of the third springs is located between two adjacent sliding sleeves. Two second limiting rings are provided. The upper second limiting ring is slidably connected to the screw, and the lower second limiting ring is rotatably sleeved on the top and bottom outer sides of the screw via a bearing.

[0016] This invention also provides a sampling method for a liquor sampling component used in liquor tanks, specifically including the following steps:

[0017] S1. When the lifting pressure plate is in the starting position, start the drive motor. After the drive motor starts, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the driven gear to rotate through the drive gear. When the driven gear rotates, it drives multiple mixing rods to rotate through the screw, the second slide groove, the sliding column and the sliding sleeve, thereby mixing the wine inside the tank.

[0018] S2. When the reciprocating screw rotates, it drives the lifting pressure plate to continuously descend. When the lifting pressure plate descends, it presses down on the second limiting ring located above. When the second limiting ring descends, it presses down on the uppermost sliding sleeve. At this time, multiple third springs are gradually compressed, and multiple sliding sleeves drive multiple mixing rods to descend, thereby continuously mixing the wine.

[0019] S3. When the lifting pressure plate descends to the first threshold, the lifting pressure plate contacts the annular rotating plate. Then the lifting pressure plate drives the annular rotating plate to descend. The annular rotating plate drives the lifting piston to descend inside the sampling cylinder through the annular sleeve plate and the piston rod. At this time, the first spring is stretched, and the air inside the sampling cylinder is discharged through the drain plate, the one-way drain pipe and the telescopic drain pipe.

[0020] S4. When the lifting pressure plate descends to the second threshold, the lifting pressure plate descends to the lowest position of the reciprocating screw. At this time, as the reciprocating screw continues to rotate, the lifting pressure plate gradually rises and gradually releases the pressure on the annular rotating plate. At this time, under the pull of the first spring, the T-shaped rod gradually rises inside the sampling cylinder, and the wine inside the tank is sucked in by the sampling cylinder through the one-way liquid inlet pipe.

[0021] S5. As the lifting pressure plate continues to rise, when the lifting pressure plate reaches the third threshold distance, the lifting pressure plate contacts the top of the T-shaped rod and pushes it upward. Then, the T-shaped rod pulls the drain plate through the fixed support rod, thereby causing the drain plate to rise inside the sampling cylinder. At this time, the wine inside the sampling cylinder is pressurized and enters the telescopic outlet pipe through the one-way drain pipe, and is finally discharged and the sampling is completed.

[0022] S6. When the lifting plate rises to the highest position of the reciprocating screw, the lifting plate begins to descend as the reciprocating screw continues to rotate. When the lifting plate descends to the starting position, the drive motor is stopped, and the drain plate is reset by the T-shaped rod under the push of the second spring.

[0023] The technical effects and advantages of this invention are as follows:

[0024] This invention comprises a driving mechanism, an exhaust and liquid inlet mechanism, an exhaust and liquid outlet mechanism, and a wine mixing mechanism. The driving mechanism sequentially drives these three mechanisms. The wine mixing mechanism mixes the wine after being driven. The exhaust and liquid inlet mechanism first expels internal air and then draws in the wine. The exhaust and liquid outlet mechanism then discharges the wine from the exhaust and liquid inlet mechanism, thus completing the sampling process. Compared to similar devices in the prior art, this invention can mix the wine before sampling, avoiding the need for multiple samplings and increasing operational difficulty. Furthermore, it effectively prevents air from entering the tank and contaminating the wine during sampling. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This invention provides, for example Figure 1-5The present invention relates to a liquor sampling assembly for a liquor tank, comprising a tank body 1, a base 2 fixedly disposed at the bottom of the tank body 1, and a detachable lid 3 disposed at the top of the tank body 1. A driving mechanism 4 is provided on the top and inside of the tank body 1. An exhaust and liquid inlet mechanism 5 is provided at the bottom of the driving mechanism 4. An exhaust and liquid outlet mechanism 6 is provided at the bottom and inside of the exhaust and liquid inlet mechanism 5. A liquor mixing mechanism 7 is provided on both sides of the exhaust and liquid inlet mechanism 5.

[0034] like Figure 3 As shown, the drive mechanism 4 includes a drive motor 41, a reciprocating lead screw 42, a drive gear 43, and a lifting pressure plate 44. The drive motor 41 is fixedly mounted on the top of the tank body 1. The reciprocating lead screw 42 is located inside the tank body 1 and is connected to the drive motor 41 in a transmission manner. The drive gear 43 is fixedly sleeved on the top outer side of the reciprocating lead screw 42. The lifting pressure plate 44 is sleeved on the outer side of the reciprocating lead screw 42 and is connected to the reciprocating lead screw 42 in a transmission manner through a reciprocating thread.

[0035] By setting the above structure, the drive motor 41 can drive the reciprocating screw 42, the reciprocating screw 42 drives the drive gear 43 to rotate continuously, the drive gear 43 drives the two wine mixing mechanisms 7, and at the same time, when the reciprocating screw 42 rotates, it drives the lifting pressure plate 44 to rise and fall.

[0036] like Figure 4 As shown, the exhaust and liquid inlet mechanism 5 includes a sampling cylinder 51, a one-way liquid inlet pipe 52, a lifting piston 53, a piston rod 54, a first spring 55, an annular sleeve plate 56, and an annular rotating plate 57. The sampling cylinder 51 is fixedly sleeved on the bottom outer side of the reciprocating screw 42. Multiple one-way liquid inlet pipes 52 are provided, uniformly and fixedly extending through the bottom outer side of the sampling cylinder 51. The lifting piston 53 is slidably disposed inside the sampling cylinder 51. Two piston rods 54 and two first springs 55 are provided, slidably extending through the top two sides of the sampling cylinder 51 and fixedly connected to the lifting piston 53. Two first springs 55 are respectively sleeved on the outside of the two piston rods 54. The annular sleeve plate 56 is slidably sleeved on the outside of the reciprocating screw 42 and fixedly connected to the two piston rods 54. The annular rotating plate 57 is rotatably sleeved on the outside of the annular sleeve plate 56 via bearings.

[0037] By setting up the above structure, when the annular rotating plate 57 is pressed down, the annular sleeve plate 56 and the piston rod 54 drive the lifting piston 53 to descend, thereby venting the air inside the sampling cylinder 51. When the lifting piston 53 is reset under the action of the first spring 55, the wine inside the tank 1 can be drawn through the one-way liquid inlet pipe 52, and the wine enters the sampling cylinder 51 through the one-way liquid inlet pipe 52.

[0038] like Figure 3 and Figure 4 As shown, the exhaust and liquid discharge mechanism 6 includes a first limiting ring 61, a drain plate 62, a T-shaped rod 63, a fixed support rod 64, a receiving groove 65, a first sliding groove 66, a second spring 67, a one-way drain pipe 68, and a telescopic drain pipe 69. The first limiting ring 61 is fixedly disposed at the bottom inner side of the sampling cylinder 51. The drain plate 62 is slidably disposed inside the sampling cylinder 51 and located at the top of the first limiting ring 61. The T-shaped rod 63 is located inside the drain plate 62. Multiple fixed support rods 64 are evenly fixedly disposed outside the T-shaped rod 63 and are all fixedly connected to the inner wall of the drain plate 62. The receiving groove 65 is opened inside the reciprocating screw 42, the first sliding groove 66 is opened through the front of the reciprocating screw 42, the T-shaped rod 63 is slidably disposed inside the first sliding groove 66, the second spring 67 is located inside the receiving groove 65, one end of the second spring 67 is attached to the top of the T-shaped rod 63 and the other end is attached to the inner wall of the receiving groove 65, the one-way drain pipe 68 is fixedly disposed at the bottom center of the drain plate 62, and one-way valves are provided on both the one-way drain pipe 68 and the one-way inlet pipe 52, and the telescopic outlet pipe 69 is fixedly nested at the bottom of the tank body 1 and is connected to the one-way drain pipe 68 through a rotary joint.

[0039] By setting up the above structure, when the T-shaped rod 63 rises, the fixed support rod 64 drives the drain plate 62 to rise inside the sampling cylinder 51. At this time, the drain plate 62 squeezes the wine inside the sampling cylinder 51, so that the wine passes through the drain plate 62 and enters the one-way drain pipe 68, and is finally discharged through the telescopic outlet pipe 69. Subsequently, the second spring 67 can push the T-shaped rod 63, so that the T-shaped rod 63 pushes the drain plate 62 through the fixed support rod 64, so that the drain plate 62 is reset.

[0040] like Figure 3 and Figure 5As shown, the wine mixing mechanism 7 includes a screw 71, a driven gear 72, a second sliding groove 73, a sliding column 74, a sliding sleeve 75, a mixing rod 76, a third spring 77, and a second limiting ring 78. The top end of the screw 71 is rotatably nested at the bottom of the base 2 via a bearing. The screw 71 passes through and is slidably connected to the lifting pressure plate 44. The driven gear 72 is fixedly sleeved on the top outer side of the screw 71 and meshes with the driving gear 43. The second sliding groove 73 is formed through the front of the screw 71. Multiple sliding columns 74, sliding sleeves 75, mixing rods 76, and third springs 77 are provided. The sliding column 74 is uniformly slidably disposed inside the second sliding groove 73. The multiple sliding sleeves 75 are uniformly sleeved on the outside of the screw 71 and are respectively fixedly connected to the multiple sliding columns 74. The multiple mixing rods 76 are uniformly fixedly disposed on both sides of the multiple sliding sleeves 75. The multiple mixing rods 76 are uniformly sleeved on the outside of the screw 71. Any one of the third springs 77 is located between two adjacent sliding sleeves 75. There are two second limiting rings 78. The upper second limiting ring 78 is slidably connected to the screw 71. The lower second limiting ring 78 is rotatably sleeved on the top and bottom of the outside of the screw 71 through a bearing.

[0041] By setting the above structure, when the driven gear 72 rotates, the screw 71 drives multiple mixing rods 76 to rotate through the second sliding groove 73, the sliding column 74 and the sliding sleeve 75, thereby mixing the wine. At the same time, when the uppermost second limiting ring 78 is pressed down, the second limiting ring 78 presses down on the uppermost sliding sleeve 75. At this time, multiple third springs 77 are compressed and shortened. Subsequently, multiple sliding sleeves 75 drive multiple mixing rods 76 to descend, thereby adjusting the mixing position and enhancing the mixing effect.

[0042] Example 2

[0043] This invention also provides a sampling method for a liquor sampling component used in liquor tanks, specifically including the following steps:

[0044] S1. When the lifting pressure plate 44 is in the starting position, the drive motor 41 is started. After the drive motor 41 starts, it drives the reciprocating screw 42 to rotate. When the reciprocating screw 42 rotates, it drives the driven gear 72 to rotate through the driving gear 43. When the driven gear 72 rotates, it drives multiple mixing rods 76 to rotate through the screw 71, the second slide groove 73, the sliding column 74 and the sliding sleeve 75, thereby mixing the wine inside the tank 1.

[0045] S2. When the reciprocating screw 42 rotates, it drives the lifting pressure plate 44 to continuously descend. When the lifting pressure plate 44 descends, it presses down on the second limiting ring 78 located above. When the second limiting ring 78 descends, it presses down on the uppermost sliding sleeve 75. At this time, multiple third springs 77 are gradually compressed, and multiple sliding sleeves 75 respectively drive multiple mixing rods 76 to descend, thereby continuously mixing the wine.

[0046] S3. When the lifting pressure plate 44 descends to the first threshold, the lifting pressure plate 44 contacts the annular rotating plate 57. Then the lifting pressure plate 44 drives the annular rotating plate 57 to descend. The annular rotating plate 57 drives the lifting piston 53 to descend inside the sampling cylinder 51 through the annular sleeve plate 56 and the piston rod 54. At this time, the first spring 55 is stretched, and the air inside the sampling cylinder 51 is discharged through the drain plate 62, the one-way drain pipe 68 and the telescopic drain pipe 69.

[0047] S4. When the lifting pressure plate 44 descends to the second threshold, the lifting pressure plate 44 descends to the lowest position of the reciprocating screw. At this time, as the reciprocating screw 42 continues to rotate, the lifting pressure plate 44 gradually rises and gradually releases the pressure on the annular rotating plate 57. At this time, under the pull of the first spring 55, the T-shaped rod 63 gradually rises inside the sampling cylinder 51, and the wine inside the tank 1 is sucked in by the sampling cylinder 51 through the one-way liquid inlet pipe 52.

[0048] S5. As the lifting pressure plate 44 continues to rise, when the lifting pressure plate 44 reaches the third threshold distance, the lifting pressure plate 44 contacts the top of the T-shaped rod 63 and pushes it upward. Then, the T-shaped rod 63 pulls the drain plate 62 through the fixed support rod 64, thereby causing the drain plate 62 to rise inside the sampling cylinder 51. At this time, the wine inside the sampling cylinder 51 is pressurized and enters the telescopic liquid outlet pipe 69 through the one-way drain pipe 68, and is finally discharged and the sampling is completed.

[0049] S6. When the lifting plate 44 rises to the highest position of the reciprocating screw, the lifting plate 44 begins to descend as the reciprocating screw 42 continues to rotate. When the lifting plate 44 descends to the starting position, the drive motor 41 is stopped, and the drain plate 62 is reset by the T-shaped rod 63 under the push of the second spring 67.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

When the driven gear (72) rotates, it drives multiple mixing rods (76) to rotate through the screw (71), the second slide groove (73), the sliding column (74) and the sliding sleeve (75), thereby mixing the wine inside the tank (1). S2. When the reciprocating screw (42) rotates, it drives the lifting pressure plate (44) to continuously descend. When the lifting pressure plate (44) descends, it presses down on the second limiting ring (78) located above. When the second limiting ring (78) descends, it presses down on the uppermost sliding sleeve (75). At this time, multiple third springs (77) are gradually compressed, and multiple sliding sleeves (75) drive multiple mixing rods (76) to descend, thereby continuously mixing the wine. S3. When the lifting pressure plate (44) descends to the first threshold, the lifting pressure plate (44) contacts the annular rotating plate (57). Then the lifting pressure plate (44) drives the annular rotating plate (57) to descend. The annular rotating plate (57) drives the lifting piston (53) to descend inside the sampling cylinder (51) through the annular sleeve plate (56) and the piston rod (54). At this time, the first spring (55) is stretched, and the air inside the sampling cylinder (51) is discharged through the drain plate (62), the one-way drain pipe (68), and the telescopic drain pipe (69). S4. When the lifting pressure plate (44) descends to the second threshold, the lifting pressure plate (44) descends to the lowest position of the reciprocating screw. At this time, as the reciprocating screw (42) continues to rotate, the lifting pressure plate (44) gradually rises and gradually releases the pressure on the annular rotating plate (57). At this time, under the pull of the first spring (55), the T-shaped rod (63) gradually rises inside the sampling cylinder (51), and the wine inside the tank (1) is sucked in by the sampling cylinder (51) through the one-way liquid inlet pipe (52). S5. As the lifting pressure plate (44) continues to rise, when the lifting pressure plate (44) reaches the third threshold distance, the lifting pressure plate (44) contacts the top of the T-shaped rod (63) and pushes it upward. Then the T-shaped rod (63) pulls the drain plate (62) through the fixed support rod (64), thereby causing the drain plate (62) to rise inside the sampling cylinder (51). At this time, the wine inside the sampling cylinder (51) is pressurized and enters the telescopic outlet pipe (69) through the one-way drain pipe (68), and is finally discharged and the sampling is completed. S6. When the lifting plate (44) rises to the highest position of the reciprocating screw, the lifting plate (44) begins to descend as the reciprocating screw (42) continues to rotate. When the lifting plate (44) descends to the starting position, the drive motor (41) is stopped, and the drain plate (62) is reset by the T-shaped rod (63) under the push of the second spring (67).
