The bottom of the top plate is fixedly connected to a pull rod, the bottom of the pull rod is fixedly connected to a plug pad, the bottom of the shell is fixedly connected to a straw, the bottom of the straw is fixedly connected to a filter, the right side of the shell is provided with a delivery hole, and the left side of the sampling mechanism is plugged with a sample box. In the above patent, the sampling tube is a whole, and the entire sampling tube needs to be placed in the rice wine barrel when in use. When the length of the sampling tube is long, it is difficult to put it into the rice wine barrel. Summary of the invention

[0004] The invention provides a rice wine sampling device for rice wine brewing, so as to solve the technical problem that a long sampling tube is difficult to be put into a rice wine barrel.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] A rice wine sampling device for rice wine brewing, comprising a sampling tube and a mounting mechanism, wherein the sampling tubes are multiple, comprising an inner tube and an outer tube rotatably mounted outside the inner tube, wherein the outer wall of the inner tube is tightly fitted with the inner wall of the outer tube, a key bar is fixedly arranged at one end of the inner tube, and a key groove adapted to the key bar is arranged at the other end, and a liquid inlet hole 1 is arranged on the side wall of the inner tube; a receiving hole is arranged on the side wall of one end of the outer tube, and a clamping block adapted to the receiving hole is connected to the other end through an elastic member, and a liquid inlet hole 2 is arranged on the side wall of the outer tube corresponding to the liquid inlet hole 1; the mounting mechanism comprises a mounting frame, a clamping lifting assembly and a top pressing assembly The mounting frame is provided with a through hole three for the sampling tube to pass vertically, the clamping and lifting assembly includes at least four clamping plates, and the multiple clamping plates are evenly distributed in a circle around the three axes of the through hole, each clamping plate is connected with a horizontal driving mechanism one for driving the clamping plate to approach or move away from the three axes of the through hole and a longitudinal driving mechanism for driving the clamping plate to move up and down, the pressing assembly includes a pressing rod and a horizontal driving mechanism two for driving the pressing rod to reciprocate radially along the three axes of the through hole, the pressing rod corresponds to the accommodating hole, and the horizontal driving mechanism two is used to drive the card block to disengage from the accommodating hole.

[0007] The beneficial effects are as follows: there are multiple sampling tubes, and the sampling tubes are fixedly connected up and down through the cooperation of the accommodating hole and the clamping block, so that the sampling tube can be easily put into the rice wine barrel. When the sampling is completed, the sampling tube moves to a specific position under the drive of the clamping drive mechanism, and the push rod pushes the clamping block away from the accommodating hole. At this time, the sampling tube can be easily removed, and the use is simple; the adjacent inner tubes are key-connected, and the inner tube at the top can be rotated so that all the liquid inlet holes 1 and all the liquid inlet holes 2 are opposite to each other, so that the liquid in the rice wine barrel can enter the inner tube. After the sampling is completed, the inner tube is rotated in the opposite direction, and the liquid inlet hole 1 is closed by the outer tube, so that the rice wine liquids at different positions are prevented from mixing in the inner tube, so as to ensure that the detection of the sampling results can accurately reflect the fermentation conditions of rice wines with different heights.

[0008] Furthermore, one end of the inner tube is fixedly assembled with a vertical rod 2 which is coaxial with the inner tube, a torsion spring is mounted on the vertical rod 2, and two ends of the torsion spring are respectively fixed on the vertical rod 2 and the inner wall of the outer tube, a protrusion 1 is fixed on the vertical rod 2, and the inner wall of the outer tube is provided with a protrusion 2 and a protrusion 3, protrusion 1 is located between the two protrusions 2 and 3, and the torsion spring has elastic potential energy that causes protrusion 1 to always be in pressing contact with protrusion 2, when protrusion 1 is in contact with protrusion 2, there is a gap between liquid inlet hole 1 and liquid inlet hole 2, and when protrusion 1 is in contact with protrusion 3, liquid inlet hole 1 is opposite to liquid inlet hole 2.

[0009] The beneficial effects are: the setting of protrusion one, protrusion two and protrusion three facilitates the user to locate the position of the inner tube relative to the outer tube, thereby helping the user to accurately grasp the positions of liquid inlet hole one and liquid inlet hole two; the setting of the torsion spring can fix the position of the inner tube when not subject to external force, making it convenient for the key strip to be installed in the key slot.

[0010] Furthermore, the inner wall of the outer tube has a slide groove extending up and down and connected to the accommodating hole, the slide groove is located above the accommodating hole, and the inner wall of the outer tube between two adjacent slide grooves has a horizontally arranged flange. When the card block is located outside the slide groove, the bottom end surface of the card block contacts the top surface of the flange. When the card block is located in the slide groove, the card block moves downward into the accommodating hole, and the key bar enters the key groove.

[0011] The beneficial effect is that when the card block and the slide groove do not correspond, the key bar and the key groove do not correspond to each other, and the card block cannot move down due to the obstruction of the flange. At this time, there is a gap between the top surface of the key bar and the bottom surface of the inner tube in the vertical direction; when the card block is located in the slide groove, the key bar and the key groove correspond up and down. At this time, the card block is moved down, and the key bar is engaged in the key groove. The setting of the flange makes it convenient for the user to adjust the position of the card block, ensuring that the key bar can be smoothly inserted into the key groove.

[0012] Furthermore, an annular color ribbon 2 is provided on the outer circumferential surface of the outer tube, and the color ribbon 2 includes color block 2 and color block 1 located between the color block 2, and the color block 2 corresponds to the accommodating hole up and down. A positioning component is also provided on the mounting mechanism, and the positioning component includes a color sensor and a motor 1 driving the clamping and lifting mechanism to rotate around the three axes of the through hole. The color sensor and the motor 1 are both fixedly assembled on the mounting frame. When the color sensor detects color block 1, the clamping and lifting mechanism stops running. When the motor 1 drives the clamping and lifting mechanism to rotate until the color sensor detects color block 2, the clamping and lifting mechanism continues to work.

[0013] The beneficial effect is that the arrangement of the second color ribbon and the positioning assembly can locate the circumferential position of the outer tube, ensure that the accommodating hole corresponds to the push rod, and facilitate the separation of the sampling tubes.

[0014] Furthermore, a worm wheel 1 is rotatably assembled in the mounting frame, a clamping and lifting mechanism is assembled on the worm wheel 1, the worm wheel 1 engages with a worm gear 1, the worm gear 1 is connected to an output shaft of a motor 1, and the motor 1 is used to drive the worm wheel 1 to rotate around the three axes of the through hole.

[0015] The beneficial effect is that when two sampling tubes are connected, friction is generated between the block and the inner wall of the outer tube. Due to the self-locking properties of worm gear one and worm gear two, the rotation of worm gear one is effectively prevented, thereby ensuring the stability of the device during use.

[0016] Furthermore, the horizontal driving mechanism 2 includes a vertical rod 3, a worm gear 2 and a motor 2. The worm gear 2 is rotatably assembled in the mounting frame, the vertical rod 3 is fixed on the top pressure rod, and the worm gear 2 has a long hole for the vertical rod 3 to pass through. The worm gear 2 engages with the worm gear 2, and the output shaft of the motor 2 is connected to the worm gear 2. The motor 2 is used to drive the worm gear 2 to rotate around the axis of the through hole 3, and the worm gear 2 drives the vertical rod 3 to reciprocate radially along the through hole 3.

[0017] The beneficial effect is that all the ejector rods can be driven to move synchronously through the rotation of the worm gear 2, the structure is simple, and the assembly is convenient.

[0018] Furthermore, the mounting frame is fixedly connected to a placement frame with an opening at the top, a porous plate is fixedly arranged in the placement frame, and the porous plate is provided with a plurality of through holes for vertically placing the sampling tubes.

[0019] Furthermore, a clamping mechanism is provided between the mounting frame and the placement frame, the clamping mechanism includes a vertical plate and a screw threadedly assembled on the vertical plate, the screw extends horizontally, and the screw is rotatably assembled between the mounting frame and the placement frame. The rotation of the screw is used to drive the vertical plate to approach or move away from the mounting frame.

[0020] The beneficial effects are: multiple sampling tubes can be stored in the placement rack, and the device is easy to move; the barrel wall of the rice wine barrel can be clamped between the vertical plate and the mounting rack, and the barrel wall of the rice wine barrel can also be clamped between the vertical plate and the placement rack, which is convenient for users to measure the fermentation conditions of rice wine at the same depth in different positions.

The handle 61 is turned to drive the vertical plate 58 to move along the extension direction of the screw 59. The vertical plate 58 and the placement frame 52 or the vertical plate 58 and the mounting frame 27 clamp the device on the rice wine barrel. The steps for installing and removing the sampling tube 1 are as follows:

[0045] ① Such as Fig.11 As shown, the adjustment installation mechanism is in the initial state. At this time, the push rod 44 is installed in the through hole 5 46 and does not protrude from the through hole 5 46, the driving device 2 36 and the driving device 4 38 are shortened, the distance between the clamping plate 1 33 and the clamping plate 2 34 is increased, the protrusion 1 9 is in contact with the protrusion 2 17, the torsion spring 12 has elastic potential energy to make the protrusion 1 9 and the protrusion 2 17 press and contact, and there is a gap between the liquid inlet hole 1 4 and the liquid inlet hole 2 19; the sampling tube 1 with the conical block 26 at the bottom is installed in the vertical tube 1 28;

[0046] ② Move the sampling tube 1 downward. There is a gap between the outer peripheral surface of the sampling tube 1 and the inner concave surface of the clamping plate 1 33 and the clamping plate 2 34. Fig.12 As shown, when the color sensor senses the color ribbon 3 14, the driving device 2 36 is shortened, the inner concave surface of the clamping plate 1 33 is pressed against the outer peripheral surface of the sampling tube 1 to clamp and fix the sampling tube 1, and the driving device 1 35 is shortened to drive the sampling tube 1 to move downward;

[0047] ③ When the driving device 1 35 is shortened to the shortest, the driving device 4 38 is extended, the clamping plate 2 34 clamps the sampling tube 1, the driving device 2 36 is shortened, the clamping plate 1 33 is separated from the sampling tube 1, and then the driving device 1 35 is extended, the driving device 3 37 is shortened, and the sampling tube 1 continues to move downward; when the driving device 3 37 is shortened to the shortest, the driving device 1 35 is extended to the longest, the clamping plate 1 33 clamps the sampling tube 1, the clamping plate 2 34 releases the sampling tube 1, the driving device 1 35 is shortened, and the sampling tube 1 continues to move downward, and the driving device 1 35, the driving device 2 36, the driving device 3 37, and the driving device 4 38 are extended and shortened in turn, and the sampling tube 1 continues to move downward until the color sensor 40 detects the color ribbon 2;

[0048] ④ Such as Fig.13 As shown, refer to Fig.11 When the color sensor 40 detects the color block 15, the motor 1 41 starts, drives the worm gear 1 42 to rotate, and the worm gear 1 42 drives the clamping lifting assembly to rotate. When the color sensor 40 detects the color block 2 16, the motor 1 41 stops, and the through hole 5 46 is opposite to the receiving hole 20. The setting of the color ribbon 3 14 can make the speed of the color ribbon 2 moving down controllable, so as to avoid the situation that the sampling tube 1 moves down too fast and the color ribbon 2 cannot be detected.

[0049] ⑤ When the color sensor 40 detects the color block 2 16, the drive device 1 35, the drive device 2 36, the drive device 3 37, and the drive device 4 38 restart, driving the sampling tube 1 to continue to move downward until the color sensor 40 detects the color ribbon 13, and the drive device 1 35, the drive device 2 36, the drive device 3 37, and the drive device 4 38 stop running; the sampling tube 1 with the block 24 at the bottom is installed in the vertical tube 1 28, and the guide surface 25 presses against the inner surface of the mounting frame 27. At the top of the outer tube 3, when the block 24 moves downward, the elastic member 23 is deformed, and the block 24 enters the outer tube 3 located below. When the block 24 does not enter the chute 21, the flange 22 blocks the sampling tube 1 located above from continuing to move downward, and the sampling tube 1 located above is rotated until the block 24 enters the chute 21, and the sampling tube 1 located above can move downward. At this time, the key bar 6 is opposite to the key bar 6, and the sampling tube 1 is moved downward, the block 24 is engaged in the receiving hole 20, and the key bar 6 is engaged in the key groove 10;

[0050] ⑥ Start the driving device 1 35, the driving device 2 36, the driving device 3 37, and the driving device 4 38, and the two sampling tubes 1 move downward synchronously, and repeat steps ② to ⑤ until a suitable number of sampling tubes 1 are connected together and placed in the rice wine barrel;

[0051] ⑦ Use wire cutters, wrenches or other tools to clamp the key strip 6 and rotate it to drive all the inner tubes 2 to rotate until the protrusion 19 contacts the protrusion 3 18, and the key strip 6 cannot continue to rotate. At this time, the liquid inlet hole 14 and the liquid inlet hole 2 19 are opposite, and the rice wine liquid enters the inner tube 2 along the liquid inlet hole 14 and the liquid inlet hole 2 19. After a period of time, rotate the key strip 6 in the opposite direction until the protrusion 19 returns to the state in step ①, and the sampling is completed;

[0052] ⑧ After the sampling is completed, the driving device 1 35, the driving device 2 36, the driving device 3 37 and the driving device 4 38 are started, and the sampling tube 1 at the top is gradually moved upward by the alternating clamping of the clamping plate 1 33 and the clamping plate 2 34.
