Description

Technical Field

[0001] The utility model relates to the technical field of liquor fermentation equipment, in particular to a convenient cellar mud sampling device. Background Art

[0002] There are currently twelve types of Chinese liquor flavors, some require cellar mud, and some do not, but cellar mud is indispensable for strong-flavor liquor, and the quality of the cellar mud directly determines the quality of the liquor; at the same time, cellar mud is a carrier and habitat for various beneficial microorganisms such as caproic acid bacteria, methanogens, butyric acid bacteria, and is also a breeding ground for them. The types and quantities of these beneficial microorganisms are a standard for measuring the quality of cellar mud, and are called "microbial gold" by the scientific and technological community.

[0003] At present, there is no direct sampling equipment for the sampling and analysis of the cellar mud samples of Luzhou-flavor liquor. The traditional sampling method is to shovel at the bottom or wall of the cellar with hard objects such as iron shovels. This sampling method not only cannot accurately intercept the cellar mud at a certain position, but also in the sampling process, the surface layer, middle layer and bottom layer of the sample cellar mud will contaminate each other, causing damage to the microorganisms in the bottom layer of the sample cellar mud, making the obtained cellar mud not very representative; at the same time, when using hard objects such as iron shovels for sampling, it is not possible to well locate the microorganisms and physical and chemical conditions of samples at different depths. Therefore, in order to solve the above technical problems, some manufacturers spontaneously designed cellar mud sampling devices.

[0004] For example, the utility model patent with the publication number CN209148340U discloses a cellar mud sampling device, including an internally connected T-shaped outer tube, a short horizontal tube section as a handle, and a long vertical tube section as a sampling section; a scale area arranged from the bottom to the top and along the axial direction is provided on the outer wall of the sampling section, and the end is a conical tip and open, which serves as an insertion end; one end of the connecting rod is connected to the horizontal handle, and the whole is a T-shaped structure, and the other end is connected to the center of the circular inner push piece; an opening is provided on the handle at the extended intersection of the sampling section, and the aperture of the opening is the same as the tube diameter of the sampling section; the outer dimensions of the circular inner push piece match the shape and dimensions of the cross section of the sampling section. Although the cellar mud sampling device has a simple structure and is convenient for sampling, the cellar mud needs to be pushed out of the sampling section through the circular inner push piece after sampling, and the surface layer, middle layer and bottom layer of the cellar mud are easily contaminated with each other during the process.

[0005] The utility model patent with publication number CN217845692U discloses a pit mud sampler, which includes a plurality of arc tiles that open and close together to form a cylinder, and a cutting edge is provided at the same end of the plurality of arc tiles; at the same time, two arc tiles are hinged and fixed on one side, and a locking mechanism for locking the two arc tiles is also provided on the cylinder. Although the pit mud sampler can achieve accurate sampling and prevent the pit mud surface layer, the pit mud middle layer, and the pit mud bottom layer from being contaminated with each other after sampling, after sampling the pit mud, the worker needs to manually unlock the locking mechanism and then manually open the two arc tiles, and the whole operation process is cumbersome.

[0006] Therefore, there is an urgent need for a pit mud sampler which is convenient for sampling and will not affect the analysis result. Utility Model Content

[0009] Furthermore, a fixing ring is installed on the driving rod, and the inner ends of the multiple connecting rods are hinged on the fixing ring.

[0010] Furthermore, a guide block is mounted on the driving rod and is slidably matched with the inner wall of the T-shaped rod.

[0013] Furthermore, a limiting end plate is fixed to the lower end of the driving rod to prevent the movable ring from falling off.

[0014] Furthermore, the T-shaped rod includes a sleeve vertically mounted on the top cover and a handle fixed on the upper end of the sleeve, and the gripping portion is parallel to the handle.

[0015] Furthermore, the handle and the gripping portion are both covered with a soft rubber layer.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations. It is to be understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figure 1 , Figure 2 As shown, the utility model provides a convenient cellar mud sampling device, comprising a sampling tube 1, a T-shaped rod 2, and a driving rod 3. The sampling tube 1 is used for sampling cellar mud, and one end of the sampling tube 1 for inserting into the cellar mud is open. The center line of the sampling tube 1, the center line of the T-shaped rod 2, and the center line of the driving rod 3 are all on the same straight line.

[0031] The sampling tube 1 includes a top cover 101 and a barrel 102. The diameter of the barrel 102 is equal to the diameter of the top cover 101, and the barrel 102 is formed by a plurality of arc-shaped tiles 102a that open and close in coordination with each other. Specifically, the cross-section of the arc-shaped tiles 102a is arc-shaped, and the plurality of arc-shaped tiles 102a are hinged to the top cover 101 by hinges, so that the plurality of arc-shaped tiles 102a can be flipped on the top cover 101. When the plurality of arc-shaped tiles 102a are closed together, the barrel 102 is formed. When the plurality of arc-shaped tiles 102a are flipped outward at the same time, the barrel 102 is in a flower shape.

[0032] An ear seat is installed on one end of the inner side surface of each arc-shaped tile 102a close to the top cover 101, and a swingable connecting rod 12 is installed on the ear seat. The other ends of multiple connecting rods 12 are hinged on the driving rod 3. When the driving rod 3 moves, the connecting rod 12 is driven to move. When the connecting rod 12 moves, it pulls or pushes the arc-shaped tile 102a, so that the arc-shaped tile 102a is flipped on the top cover 101, so that the multiple arc-shaped tiles 102a are closed together to form the cylinder 102, and the multiple arc-shaped tiles 102a are opened to form a flower shape with the top cover 101.

[0033] In order to facilitate driving the driving rod 3, one end of the driving rod 3 away from the connecting rod 12 passes through the top cover 101 and extends into the T-shaped rod 2, and a gripping portion 11 is installed on the end of the driving rod 3 extending into the T-shaped rod 2, so that the gripping portion 11 extends along the radius direction of the T-shaped rod 2 and passes through the T-shaped rod 2. Since the driving rod 3 drives the connecting rod 12 to push or pull the arc-shaped shoe 102a, the driving rod 3 reciprocates along its axial direction, so in order to ensure that the driving rod 3 will not be hindered by the cooperation between the gripping portion 11 and the T-shaped rod 2 during the movement, a long hole 201a for the gripping portion 11 to move up and down is also opened on the T-shaped rod 2, and the length of the long hole 201a is not less than the movement distance of the driving rod 3, and the width of the long hole 201a is adapted to the width of the gripping portion 11; at the same time, in order to ensure the reciprocating movement of the driving rod 3, the driving rod 3 passes through the top cover 101 and slides with the top cover 101.

[0034] As a further improvement of this embodiment, in order to facilitate the hinge connection between the connecting rod 12 and the driving rod 3, a fixing ring 4 is also installed on the driving rod 3, and the fixing ring can be directly welded to the driving rod 3. The fixing ring 4 is installed with an ear seat for hinged installation of the connecting rod 12. The number of the ear seats is equal to the number of the connecting rods 12, and each connecting rod 12 corresponds to an ear seat. By installing the fixing ring 4 on the driving rod 3, the installation of the ear seat is more convenient, thereby facilitating the hinge connection between the connecting rod 12 and the driving rod 3.

[0035] As a further improvement of this embodiment, a guide block 10 is further installed on the driving rod 3, and the outer wall of the guide block 10 is slidably matched with the inner wall of the T-shaped rod 2. The guide block 10 is matched with the inner wall of the T-shaped rod 2, so that the end of the driving rod 3 extending to the inside of the T-shaped rod 2 will not shake left and right, ensuring that the driving rod 3 always stays on the same straight line during the movement, thereby ensuring that the end of the driving rod 3 located in the sampling tube 1 is always located at the center of the sampling tube 1, so that the flipping degree of multiple arc tiles 102a is consistent when the driving rod 3 is in motion, so that the multiple arc tiles 102a form a complete cylinder 102 after being closed together, and avoid the existence of gaps between two adjacent arc tiles 102a after the multiple arc tiles 102a are closed together.

[0036] As a further improvement of the present embodiment, a telescopic spring 9 is also sleeved on the driving rod 3, one end of the telescopic spring 9 is pressed against the guide block 10, and the other end of the telescopic spring 9 is pressed against the top cover 101. On the one hand, when sampling the cellar mud, the present invention can not only drive the driving rod 3 upward through the gripping portion 11, but also push the driving rod 3 upward through the elastic force of the telescopic spring 9 itself, thereby ensuring that the multiple arc tiles 102a are closed together, so that during the cellar mud sampling process, the staff does not need to apply too much force to drive the driving rod 3, making the cellar mud sampling process easier; on the other hand, after the cellar mud sampling is completed, the telescopic spring 9 pushes the driving rod 3 upward through its own elastic force, thereby ensuring that the multiple arc tiles 102a are closed together, avoiding the multiple arc tiles 102a from flipping over at will when the present invention is stored, making the storage of the present invention more convenient.

[0037] As a further improvement of this embodiment, a top plate 7 is further provided in the sampling tube 1, and the diameter of the top plate 7 is adapted to the inner diameter of the cylinder 102 formed after the multiple arc-shaped tiles 102a are closed together, and the lower end of the driving rod 3 is also sleeved with a movable ring 5 that can slide up and down, and the movable ring 5 is located below the fixed ring 4. A plurality of connecting rods 6 are also connected between the movable ring 5 and the top plate 7, and the plurality of connecting rods 6 are evenly spaced along the circumferential direction of the movable ring 5. On the one hand, the top plate 7 can not only effectively prevent the cellar mud from acting on the connecting rod 12 during the cellar mud sampling process, but also push the top plate 7 upward during the sampling process when the depth of the cellar mud is large, thereby avoiding the top plate 7 from squeezing the cellar mud; on the other hand, the top plate 7 can effectively prevent the multiple arc-shaped tiles 102a from deforming the cylinder 102 due to transitional closure during the common closure process, thereby avoiding affecting the sampling of the cellar mud and ensuring that the sampled cellar mud is cylindrical.

[0038] As a further improvement of this embodiment, in order to prevent the movable ring 5 from falling off from the driving rod 3, a limiting end plate 8 is further fixed at the lower end of the driving rod 3, and the diameter of the limiting end plate 8 is larger than the inner diameter of the movable ring 5. Of course, in order to prevent the movable ring 5 from falling off, a stopper or other structure can also be directly fixed on the outer circumferential surface of the lower end of the driving rod 3.

[0039] As a further improvement of this embodiment, the T-shaped rod 2 includes a sleeve 201 and a handle 202, the sleeve 201 is the vertical section of the T-shaped rod 2, the handle 202 is the horizontal section of the T-shaped rod 2, the sleeve 201 is fixed on the top cover 101, the upper end of the driving rod 3 is located in the sleeve 201, and the outer wall of the guide block 10 and the inner wall of the sleeve 201 have a sliding clearance fit; the holding portion 11 is parallel to the handle 202, and the holding portion 11 is close to the handle 202, so that the handle 202 and the holding portion 11 can be held at the same time during the cellar mud sampling process, making sampling more convenient.

[0040] As a further improvement of the present embodiment, the handle 202 and the gripping portion 11 are both covered with a soft rubber layer, so that the handle 202 and the gripping portion 11 feel more comfortable, thereby avoiding abrasion of the palms of the staff during the pit mud sampling process.

[0041] In the utility model, one of the arc tiles 102a or multiple arc tiles 102a are also provided with scale lines, so that the depth of the cylinder 102 inserted into the cellar mud can be observed while sampling the cellar mud, thereby obtaining the thickness of the cellar mud, which is convenient for the subsequent analysis and detection of the sampled cellar mud.

[0042] As a further improvement of the present embodiment, a cutting edge is provided at one end of the arc-shaped tile 102a away from the top cover 101, and the cross section of the cutting edge is V-shaped, so that the arc-shaped tile 102a can be smoothly inserted into the pit mud.

[0043] When the utility model is in use, the staff holds the handle 202 and simultaneously grasps the gripping portion 11 to move closer to the handle 202, the gripping portion 11 drives the driving rod 3 to move upward, while the driving rod 3 moves upward, the telescopic spring 9 pushes the guide block 10 to move upward by its own elastic force, and the guide block 10 drives the driving rod 3 to move upward; while the driving rod 3 moves upward, it drives the connecting rod 12 to pull the arc-shaped tile 102a, so that a plurality of arc-shaped tiles 102a move toward the center at the same time, and when the plurality of arc-shaped tiles 102a move toward the center at the same time, they will be restricted by the top plate 7, so that the plurality of arc-shaped tiles 102a will not move toward the center after forming the cylinder 102 together; then, the cylinder 102 is inserted into the pit mud, the cutting edge on the arc-shaped tile 102a cuts off the pit mud, and as the cylinder 102 is inserted into the pit mud, the cylinder 102 is pushed upward. As the depth in the mud increases, a part of the cellar mud vertically enters the cylinder 102. When the cylinder 102 is inserted into the lower layer of the cellar mud, the cylinder 102 is taken out and the sampled cellar mud is retained in the cylinder 102. Finally, the cylinder 102 is placed vertically on the ground or on a workbench. The staff holds the handle 202 with one hand and pushes the gripping part 11 with the other hand to move the driving rod 3 downward. While the driving rod 3 moves downward, the guide block 10 pushes the telescopic spring 9 to be compressed. The lower end of the driving rod 3 pushes the multiple arc tiles 102a to flip outward at the same time through the connecting rod 12, so that the multiple arc tiles 102a are opened at the same time to form a flower shape with the top cover 101. The sampled cellar mud loses the embrace of the arc tiles 102a and remains on the workbench or on the ground. The sampling device is removed and the staff can sample the cellar mud.

[0044] In the present invention, the cross-section of the curved tile 102a can also be directly a straight line. In this case, multiple curved tiles 102a are spliced ​​to form a polygonal cylinder 102, and a cutting edge is set at the same end of the multiple curved tiles 102a. In this case, the cylinder 102 can also be inserted into the cellar mud to achieve sampling; at the same time, when the cross-section of the curved tile 102a in the present invention is a straight line and the multiple curved tiles 102a are spliced ​​to form a polygonal cylinder 102, the shape of the top plate 7 in the present invention should be consistent with the shape of the polygonal cylinder 102.
