Abstract
Description
Technical Field
[0001] This utility model relates to the field of pit mud sampling devices, and in particular to a precise sampling device for strong-aroma pit mud. Background Technology
[0002] In the traditional strong-aroma baijiu brewing process, the quality of the cellar mud is crucial to the formation of the liquor's flavor. The microbial community and physicochemical properties of the cellar mud often exhibit vertical stratification and regional distribution characteristics. Therefore, it is necessary to accurately obtain cellar mud samples at specific depths and angles for analysis.
[0003] However, existing pit mud sampling devices generally suffer from problems such as inaccurate sampling depth control, inability to achieve precise stratification, and difficulty in controlling the sampling angle, resulting in insufficient sample representativeness. Conventional sampling tools mostly use simple tubular structures, rely on manual experience to judge the sampling depth, and lack precise scale markings and depth locking mechanisms, which can easily lead to sampling that is too deep or too shallow, affecting the accuracy of the test data.
[0004] To address the aforementioned issues, this patent proposes a cellar mud sampling device capable of precise sampling at a fixed depth and angle, and with stratified extraction capabilities, in order to meet the refined requirements of modern brewing processes for cellar mud analysis. Utility Model Content
[0005] The main purpose of this invention is to propose a precise sampling device for strong-aroma cellar mud, which aims to solve the problems of inaccurate sampling depth control, inability to achieve precise stratification, and controllable sampling angle of existing cellar mud sampling devices.
[0006] To address the aforementioned problems, this utility model proposes a precise sampling device for aromatic cellar mud, comprising a sampling cylinder, a cutting head connected to the lower end of the sampling cylinder, and an upper cover connected to the upper end of the sampling cylinder. A depth-adjusting slide rod extends vertically through the center of the upper cover, with its lower end extending into the sampling cylinder. A depth-controlling piston is connected to the lower end of the depth-adjusting slide rod, and this piston is slidably connected inside the sampling cylinder, with a rubber sealing ring between it and the sampling cylinder. A depth control depth is provided on the outer wall of the depth-adjusting slide rod. A depth-adjusting handle is connected to the upper end of the depth-adjusting slide rod, located outside the upper end of the upper cover. A depth-limiting bolt is threadedly connected to the center of the front end of the upper cover, with its rear end extending to the outer wall of the front end of the depth-adjusting slide rod and tightly fitting against the outer wall of the depth-adjusting slide rod.
[0007] Preferably, the sampling cylinder is fitted with a limiting slip ring on the outside and slidably connected inside the limiting slip ring, and the limiting slip ring is located between the cutting head and the upper cover. An angle adjustment bracket is connected to both the left and right ends of the limiting slip ring.
[0008] Preferably, the lower side of one end of each of the two angle-adjusting rotating frame principle limiting slip rings is rotatably connected to a connecting rotating seat via an angle-adjusting rotating shaft, and the two angle-adjusting rotating shafts extend in opposite directions to the outside of the two connecting rotating seats away from one end of the angle-adjusting rotating frame.
[0009] Preferably, the lower ends of the two connecting pivots are connected to a limiting angle base plate, and a cutting groove is provided at the center of the limiting angle base plate, and the cutting groove is located directly below the cutting head.
[0010] Preferably, each of the two angle-adjusting shafts is connected to a pointer dial at the end away from the angle-adjusting frame, and the pointer dial is attached to the outer wall of the connecting base at the end away from the angle-adjusting frame.
[0011] Preferably, an angle adjustment pointer is provided on the upper side of the pointer dial away from the connecting rotary seat, and an angle adjustment scale is provided on the upper side of the connecting rotary seat near the pointer dial. A limit bolt is threadedly connected at the center of the upper end of the connecting rotary seat.
[0012] Preferably, the lower end of the limiting bolt extends to the outer wall of the upper end of the angle adjusting shaft and fits tightly against the outer wall of the angle adjusting shaft. A sampling spring is provided between the upper cover and the limiting slip ring, and the sampling spring is sleeved on the outside of the sampling cylinder.
[0013] Beneficial effects:
[0014] 1. The sampling tube of this utility model is connected to a cutting head at the lower end and an upper cover with a depth adjustment slide rod at the upper end. A depth control piston is set at the lower end of the depth adjustment slide rod. The depth control piston is used to limit the cutting depth by sliding in the sampling tube.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a precise sampling device for strong-aroma cellar mud, including a sampling cylinder 1, a cutting head 2 connected to the lower end of the sampling cylinder 1, an upper cover 3 connected to the upper end of the sampling cylinder 1, a depth adjustment slide rod 4 penetrating vertically through the center of the upper cover 3, and the lower end of the depth adjustment slide rod 4 extending into the interior of the sampling cylinder 1, a depth control piston 5 connected to the lower end of the depth adjustment slide rod 4, the depth control piston 5 being slidably connected inside the sampling cylinder 1, and a rubber sealing ring provided between the piston 5 and the sampling cylinder 1, a depth control mark 6 being provided on the outer wall of the depth adjustment slide rod 4, and a depth adjustment handle 7 connected to the upper end of the depth adjustment slide rod 4, and the depth adjustment handle 7 being positioned... A depth limiting bolt 8 is threadedly connected to the center of the front end of the upper cover 3 on the outside of the upper cover 3. The rear end of the depth limiting bolt 8 extends to the outer wall of the front end of the depth adjusting slide bar 4 and fits tightly with the outer wall of the depth adjusting slide bar 4. During the sampling of the pit mud, the pit mud can be sampled at a fixed depth through the sampling tube 1. The sampling tube 1 cuts into the pit mud through the cutting head 2, and the depth of cutting is limited by the position of the depth controlling piston 5 inside the sampling tube 1, so that the pit mud enters the sampling tube 1 inside the depth controlling piston 5. The pit mud is then brought out by pulling out the sampling tube 1, thereby sampling the pit mud at a fixed depth.
[0028] The position of the depth control piston 5 inside the sampling cylinder 1 can be adjusted by sliding the depth adjustment slide rod 4 up and down inside the upper cover 3. By pulling the depth adjustment handle 7 up and down, the depth adjustment slide rod 4 is pulled up and down, and the depth control piston 5 is moved up and down inside the sampling cylinder 1, thereby adjusting the position of the depth control piston 5 inside the sampling cylinder 1, and thus adjusting the depth of the cutting head 2 into the pit mud. The depth adjustment slide rod 4 can precisely adjust the position of the depth control piston 5 by the value exposed by the depth control depth 6 on the outer wall, and can be fixed by the depth limiting bolt 8. After the depth adjustment slide rod 4 is fixed to the upper cover 3 by the depth limiting bolt 8, the depth adjustment handle 7 is pressed down. The depth adjustment handle 7 drives the upper cover 3 to move downward through the upper cover 3, and the upper cover 3 drives the sampling cylinder 1 and the cutting head 2 to cut into the pit mud.
[0029] Preferably, a limiting slip ring 9 is sleeved on the outside of the sampling cylinder 1 and slidably connected inside the limiting slip ring 9. The limiting slip ring 9 is located between the cutting head 2 and the upper cover 3. Angle adjustment brackets 10 are connected to both ends of the limiting slip ring 9. The two angle adjustment brackets 10 are rotatably connected to connecting seats 11 through angle adjustment shafts on the lower side of one end of the limiting slip ring 9. The two angle adjustment shafts extend in opposite directions to the outside of the two connecting seats 11 away from the angle adjustment brackets 10. The lower ends of the two connecting seats 11 are connected to a limiting angle base plate 12. A cutting groove 13 is opened at the center of the limiting angle base plate 12, and the cutting groove 13 is located at the cutting head 2. Directly below the infeeder 2, during the process of inserting the infeeder 2 into the pit mud, the sampling cylinder 1 and the infeeder 2 can be restricted in their position relative to the two angle-adjusting rotating frames 10 by the limiting slip ring 9, and the angle between the two angle-adjusting rotating frames 10 and the limiting angle base plate 12 can be adjusted by rotating the two angle-adjusting rotating frames 10 between the two connecting rotating seats 11. At this time, the limiting angle base plate 12 is attached to the upper end of the pit mud, and the depth adjustment handle 7 is pressed down, so that the sampling cylinder 1 slides downward inside the limiting slip ring 9, and drives the infeeder 2 to pass through the cutting groove 13 and cut into the pit mud, thereby adjusting the sampling angle of the pit mud and ensuring the diversity of pit mud sampling.
[0030] Preferably, each of the two angle-adjusting shafts is connected to a pointer dial 14 at the end away from the angle-adjusting frame 10. The pointer dial 14 is attached to the outer wall of the connecting base 11 at the end away from the angle-adjusting frame 10. An angle-adjusting pointer 15 is provided on the upper side of the pointer dial 14 at the end away from the connecting base 11. An angle-adjusting scale 16 is provided on the upper side of the connecting base 11 at the end near the pointer dial 14. A limiting bolt 17 is threadedly connected to the center of the upper end of the connecting base 11. The lower end of the limiting bolt 17 extends to the outer wall of the upper end of the angle-adjusting shaft and fits tightly against the outer wall of the angle-adjusting shaft. A sampling spring 1 is provided between the upper cover 3 and the limiting slip ring 9. 8. The sampling spring 18 is sleeved on the outside of the sampling cylinder 1. During the adjustment of the sampling angle, the angle adjustment frame 10 drives the pointer dial 14 to rotate through the adjustment shaft, and drives the angle adjustment pointer 15 to rotate through the pointer dial 14. At this time, the angle adjustment pointer 15 can accurately adjust the angle between the angle adjustment frame 10 and the angle limiting base plate 12 by pointing to the value of the angle adjustment scale 16, so that the sampling angle of the pit mud can be accurately controlled, and the sampling angle can be fixed by the tight fit between the angle limiting bolt 17 and the angle adjustment shaft, so that the pit mud can be sampled at a specific angle, which is more representative.
[0031] In addition, after the sampling tube 1 and the cutting head 2 cut into the pit mud, the pressure on the depth adjustment handle 7 is released. The upper cover 3 moves upward under the action of the sampling spring 18, and pulls the sampling tube 1 and the cutting head 2 out of the pit mud to complete the sampling. When taking out the pit mud sample from the sampling tube 1, the pit mud at different depths needs to be analyzed in layers. At this time, the depth limiting bolt 8 is loosened so that the depth adjustment slide rod 4 can slide inside the upper cover 3. The depth adjustment slide rod 4 controls the layer thickness precisely by controlling the depth 6 to shrink to the value inside the upper cover 3, so as to ensure the accurate layering of the pit mud.
[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
