Description

Technical Field

[0001] This utility model relates to the field of rice wine testing technology, and in particular to a sampling device for rice wine testing. Background Technology

[0002] In the process of large-scale production of rice wine, a comprehensive and meticulous testing process is essential to ensure that each batch of rice wine meets the established quality standards. From the selection of raw materials and the control of brewing technology to the analysis of the physicochemical indicators and flavor substances of the finished wine, strict testing of rice wine is required in many aspects.

[0003] Existing sampling methods mostly use sampling tubes. When sampling, one end of the sampling tube needs to be inserted into the rice wine. However, before sampling, one end of the existing sampling tube is exposed. During the sampling process, dust, bacteria and other contaminants may be introduced into the rice wine, thus contaminating the rice wine and affecting its quality. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: when taking samples, one end of the sampling tube needs to be inserted into the rice wine. However, before sampling, one end of the existing sampling tube is exposed. During the sampling process, dust, bacteria and other contaminants may be introduced into the rice wine, thereby contaminating the rice wine and affecting its quality. Therefore, this invention proposes a sampling device for rice wine testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampling device for testing rice wine includes a fixed cover plate, a movable hole in the middle of the fixed cover plate, a sampling tube vertically and slidably installed in the movable hole, and a piston rod sealed and slidably installed in the sampling tube.

[0007] The lower surface of the fixed cover plate is symmetrically fixed with slide rails via fixed blocks. Two sets of elastic sliding components symmetrically slide on the two slide rails, and both sealing covers are semi-circular with sealed lower ends. The lower end of the sampling tube is positioned between the two sealing covers. Guide plates are obliquely fixed on opposite sides of the two sealing covers, and the two guide plates are arranged in an inverted V-shape. The fixed cover plate is equipped with a transmission component for simultaneously moving the two sealing covers away from each other.

[0008] Preferably, the elastic sliding assembly includes two sliders fixedly mounted on the upper end of the sealing cover and two return springs respectively sleeved on two slide rails. The two sliders are respectively horizontally slidably sleeved on the two slide rails, and the two ends of the return springs are respectively fixedly connected to the fixed block and the slider.

[0009] Preferably, the upper surface of the fixed cover plate is symmetrically provided with circular holes, and the transmission assembly includes two top rods that are vertically slidably installed in the two circular holes and a U-shaped frame fixedly installed on the upper end of the two top rods. The two top rods are respectively located directly above the two guide plates.

[0010] Preferably, the lower ends of both top rods are provided with spherical grooves, and ball bearings are rolled and embedded in the spherical grooves.

[0011] Preferably, a rotating shaft is rotatably mounted on the fixed cover plate, and a stop block is fixedly mounted on the upper end of the rotating shaft.

[0012] Preferably, a first positioning ring and a second positioning ring are fixedly sleeved on the sampling tube, and the fixed cover plate is located between the first positioning ring and the second positioning ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Under the action of the elastic sliding component, the two sealing covers tend to move closer to each other. Before the sampling tube is used, the two sealing covers are in contact with each other, and the lower end of the sampling tube can be covered inside the sealing cover. During sampling, one end of the sampling tube is exposed between the two sealing covers. This can prevent dust, bacteria and other contaminants from being brought into the rice wine, avoid contamination of the rice wine, and ensure the quality of the rice wine.

[0015] 2. The two sealing covers can be moved away from each other by the cooperation of the U-shaped frame and the top rod, making operation more convenient and improving sampling efficiency. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A sampling device for testing rice wine includes a fixed cover plate 1, a movable hole is provided in the middle part of the fixed cover plate 1, a sampling tube 2 is vertically slidably installed in the movable hole, and a piston rod 3 is sealed and slidably installed in the sampling tube 2.

[0023] A slide rail 4 is horizontally and symmetrically fixed on the lower surface of the fixed cover plate 1 by a fixing block. A sealing cover 5 is symmetrically slidably installed on the two slide rails 4 by two sets of elastic sliding components. Both sealing covers 5 are semi-circular and the lower ends of both sealing covers 5 are sealed. The lower end of the sampling tube 2 is covered between the two sealing covers 5. Guide plates 6 are inclined and fixed on the opposite sides of the two sealing covers 5. The two guide plates 6 are arranged in an inverted V-shape. The fixed cover plate 1 is provided with a transmission component for simultaneously driving the two sealing covers 5 away from each other.

[0024] The upper ends of both sealing covers 5 are in sliding contact with the lower surface of the fixed cover plate 1. When the two sealing covers 5 are in contact, a sealed space is formed between them. Before the sampling device is used, the two sealing covers 5 are in contact with each other under the action of the elastic sliding component. At this time, the lower end of the sampling tube 2 is located between the two sealing covers 5, sealing the lower end of the sampling tube 2 in the sealed space, which can prevent the lower end of the sampling tube 2 from adsorbing dust, bacteria and other contaminants.

[0025] When sampling rice wine, the fixed cover plate 1 is placed on top of the rice wine container. Then, the two sealing covers 5 are moved away from each other by the transmission component, so that the lower end of the sampling tube 2 is exposed inside the rice wine container. Then, the sampling tube 2 is moved downward and the lower end of the sampling tube 2 is inserted into the rice wine. The rice wine is sucked into the sampling tube 2 by the piston rod 3. In this process, dust, bacteria and other contaminants can be avoided from being brought into the rice wine, thus avoiding contamination and ensuring the quality of the rice wine.

[0026] The elastic sliding assembly includes two sliders 7 fixedly mounted on the upper end of the sealing cover 5 and two return springs 8 respectively sleeved on the two slide rails 4. The two sliders 7 are horizontally slidably sleeved on the two slide rails 4 respectively. The two ends of the return springs 8 are fixedly connected to the fixed block and the sliders 7 respectively. The two sliders 7 on the sealing cover 5 slide horizontally on the two slide rails 4 respectively. The return springs 8 are in a compressed state. Under the action of the elastic force of the return springs 8, the two sealing covers 5 tend to move closer to each other.

[0027] The upper surface of the fixed cover plate 1 is symmetrically provided with round holes. The transmission component includes two push rods 9 that are vertically slidably installed in the two round holes and a U-shaped frame 10 fixedly installed on the upper end of the two push rods 9. The two push rods 9 are located directly above the two guide plates 6. The lower end of the two push rods 9 is provided with a spherical groove, and a ball bearing 11 is rolled and embedded in the spherical groove.

[0028] The push rod 9 is located directly above the guide plate 6. When it is necessary to move the two sealing covers 5 away from each other, press the U-shaped frame 10. The U-shaped frame 10 will simultaneously move the two push rods 9 vertically downward. The ball bearings 11 at the lower end of the push rod 9 will contact the upper surface of the guide plate 6. Since the guide plate 6 is fixedly installed on the sealing cover 5 at an angle, under the action of the guide plate 6, the push rod 9 will move the sealing cover 5 away from the sampling tube 2, thereby moving the two sealing covers 5 away from each other. The contact between the ball bearings 11 and the guide plate 6 will reduce the friction between the push rod 9 and the guide plate 6.

[0029] A rotating shaft 12 is rotatably mounted on the fixed cover plate 1. A stop block 13 is fixedly mounted on the upper end of the rotating shaft 12. When the two sealing covers 5 are far apart, the rotating shaft 12 can be rotated to drive the stop block 13 to rotate. One end of the stop block 13 can be moved to the top of the loop frame 10, thereby restricting the loop frame 10 from moving upward.

[0030] After sampling, the lower end of the sampling tube 2 is removed from the rice wine and moved to the initial position. The rotating shaft 12 is rotated again to move the stop block 13 away from the top of the loop frame 10. At this time, under the action of the return spring 8, the two sealing covers 5 move closer to each other again, covering the lower end of the sampling tube 2 inside the two sealing covers 5. The sealing covers 5 can also prevent the rice wine in the sampling tube 2 from dripping onto the ground.

[0031] The sampling tube 2 is fixedly fitted with a first positioning ring 14 and a second positioning ring 15. The fixed cover plate 1 is located between the first positioning ring 14 and the second positioning ring 15. The sampling tube 2 can slide vertically on the fixed cover plate 1. The first positioning ring 14 and the second positioning ring 15 can prevent the sampling tube 2 from detaching from the fixed cover plate 1.

[0032] In this invention, the upper ends of the two sealing covers 5 are in sliding contact with the lower surface of the fixed cover plate 1. When the two sealing covers 5 are in contact, a sealed space is formed between them. Before the sampling device is used, the two sealing covers 5 are in contact with each other under the action of the elastic sliding component. At this time, the lower end of the sampling tube 2 is located between the two sealing covers 5, sealing the lower end of the sampling tube 2 in the sealed space, which can prevent the lower end of the sampling tube 2 from adsorbing dust, bacteria and other contaminants.

[0033] When sampling rice wine, the fixed cover plate 1 is placed on top of the rice wine container. Then, the two sealing covers 5 are moved away from each other by the transmission component, so that the lower end of the sampling tube 2 is exposed inside the rice wine container. Then, the sampling tube 2 is moved downward and the lower end of the sampling tube 2 is inserted into the rice wine for sampling. In this process, it is possible to avoid bringing dust, bacteria and other contaminants into the rice wine, avoid rice wine contamination, and ensure the quality of rice wine.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
