[0001] The utility model belongs to the field of koji sampling, in particular to a sampling device for detecting microorganisms in Daqu for brewing. Background Art

[0002] Daqu is a saccharifying agent and fermenting agent for brewing, mostly a kind of crude enzyme preparation in the shape of bricks. Its microbial flora includes molds, yeasts and bacteria, and there is a certain amount of actinomycetes. It has been applied in traditional brewing industries such as liquor-making, vinegar-making and soy sauce-making for thousands of years. Among them, Daqu is mainly used for solid-state fermentation of baijiu. Daqu provides microorganisms and related enzymes for the fermentation of fermented grains, and is also a carrier of the flavor and its precursor substances of baijiu. The diversity and richness of its "bacteria, enzymes, and flavors" determine the style of baijiu; the quality of Daqu directly affects the yield and quality of Daqu liquor. The quality evaluation of the koji block usually includes sensory evaluation and physical and chemical detection, etc. The maturely cultured koji block is relatively hard and not easy to break, and its water content is usually below 14%. The physical and chemical detection of Daqu mainly includes aspects such as the water content, saccharifying power, esterifying power, and fermenting power of the koji block. During the sampling process of Daqu, employees need to use tools such as hammers to break and smash the koji blocks, then classify and select them for sampling and detection. The existing sampling method will greatly damage the overall structure of the koji block and cause material waste. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sampling device for detecting microorganisms in Daqu for brewing, which can reduce the damage to the koji block during the sampling process and avoid excessive material waste of the koji block.

[0004] The sampling device for detecting microorganisms in Daqu for brewing includes a bottom plate arranged horizontally. A number of supporting feet for supporting it are arranged on the bottom plate. Two vertically fixed supporting rods arranged at intervals and aligned are fixed on the bottom plate. A moving plate is horizontally arranged above the bottom plate. Two through holes for the independent penetration of the two supporting rods are respectively opened on the moving plate. A clamping component for clamping the koji block is arranged on the moving plate. A moving component for driving the moving plate to move up and down is arranged between the bottom plate and the moving plate. An installation box is horizontally arranged above the moving plate. A sampling tube vertically and independently penetrates through the installation box. A number of cutting teeth are arranged at the bottom of the sampling tube. A driving component for driving the sampling tube to rotate is arranged between the installation box and the sampling tube. A supporting component for supporting the installation box and adjusting its left and right movement is arranged between the two supporting rods and the installation box.

[0005] Further, the clamping component includes two baffle plates. The two baffle plates are vertically fixed symmetrically at intervals on the top of the moving plate. A threaded hole is opened on one of the baffle plates. A bolt in threaded fit with it is inserted into the threaded hole. A push plate for squeezing the koji block is fixed at one end of the bolt facing the other baffle plate.

[0006] Furthermore, the push plate and the unbolted baffle are provided with anti-slip textures to increase friction with the large curved block.

[0007] Furthermore, the movable component includes a threaded rod, and a threaded hole is provided on the base plate that is open from top to bottom and threadedly engaged with the threaded rod. The threaded rod is inserted into the threaded hole, the upper end of the threaded rod rests on the movable plate, and a handle is fixed to the lower end of the threaded rod.

[0008] Furthermore, the support assembly includes two guide rods, with mounting plates horizontally fixed to the top of the two guide rods. The two ends of the two guide rods are respectively fixed to the two mounting plates. The two guide rods are aligned with a front-to-back gap. Movable sleeves are independently fitted on the two guide rods. All movable sleeves are fixed to the mounting box, and a screw for locking is fitted on one of the movable sleeves.

[0009] Furthermore, the drive assembly includes two meshing bevel gears, a motor is mounted on the mounting box, the output end of the motor passes through the box wall and is located inside the mounting box, one bevel gear is fitted onto the output end of the motor, and the other bevel gear is fitted onto the sampling tube.

[0010] Furthermore, the sampling tube is fitted with two positioning rings that respectively fit into the inner top and inner bottom of the mounting box.

[0011] Furthermore, the outer wall of the sampling tube is provided with several chip discharge grooves for discharging cutting debris.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Place the large curved block on top of the moving plate and clamp it in place using the clamping assembly. Adjust the position of the mounting box left and right using the support assembly to align the sampling tube with the designated position on the large curved block. This allows the sampling tube to collect samples from different locations on the large curved block. Use the drive assembly to rotate the sampling tube, and then use the moving assembly to move the moving plate upwards, causing the large curved block to move upwards until the top of the large curved block is in contact with all the cutting teeth on the bottom of the sampling tube. As the sampling tube rotates, it uses its cutting teeth to rotate and cut the large curved block. The part of the large curved block that comes into contact with the cutting teeth will be cut into small fragments, which will not cause too much damage to the overall structure of the large curved block. This will avoid excessive material waste, reduce waste generation, and save time and labor costs in subsequent processing. The uncut part of the large curved block located in the middle of all the cutting teeth is the sample block, which will be inside the sampling tube. The moving plate continues to move upward, so that the sampling tube cuts through the large curved block. The sample block will be stuck inside the sampling tube. Then, it will be pushed out from the inside of the sampling tube by a stick, thus obtaining the required large curved block sample. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0020] Example 1

[0021] The microbial detection and sampling device for brewing koji described in this embodiment, such as... Figure 1 , Figure 3 and Figure 4 As shown, a base plate 12 is horizontally arranged, and a number of legs are provided on the base plate 12 for supporting it. In this embodiment, there are four legs, which are fixed to the left and right edges of the front and rear side walls of the base plate 12 respectively. The unfixed ends of all legs are tilted downward so that the unfixed ends of the legs contact the ground and support the base plate 12, so that there is a gap between the base plate 12 and the ground.

[0022] Two support rods 1 are vertically fixed on the base plate 12 and are spaced apart. The two support rods 1 are distributed on the left and right sides at intervals.

[0023] A movable plate 11 is horizontally arranged above the base plate 12, and the movable plate 11 is parallel and aligned with the base plate 12.

[0024] The movable plate 11 has two through holes for the two support rods 1 to pass through independently. When the movable plate 11 moves up and down, the two support rods 1 can guide the direction of movement of the movable plate 11 and prevent the movable plate 11 from being displaced or rotated during movement. A large curved block is placed on the top of the movable plate 11. When the movable plate 11 moves, it can drive the large curved block on it to move up and down. All the support rods 1 have size scales. When the movable plate 11 moves, the distance moved by the movable plate 11 can be confirmed by checking the position of the movable plate 11 aligned with the size scales.

[0025] To elaborate further, such as Figure 1 , Figure 3 and Figure 4 As shown, this embodiment preferably includes two baffles 10, which are vertically fixed to the top of the movable plate 11 in a symmetrical arrangement with left and right intervals. One baffle 10 has a threaded hole, and a bolt 15 with a threaded engagement is inserted into the threaded hole. A push plate 14 for pressing the large curved block is fixed to the end of the bolt 15 facing the other baffle 10. When the large curved block is placed on the top of the movable plate 11 and located between the two baffles 10, the bolt 15 is rotated to push the push plate 14 towards the large curved block. The push plate 14 pushes the large curved block against the movable plate 11. The baffle 10 in the direction of movement fits together, so that the push plate 14 and the baffle 10 that fits against the large curved block can clamp and fix the large curved block, preventing the large curved block from shifting during sampling; the whole solution constitutes a clamping assembly for clamping the large curved block; of course, the clamping assembly can also use an electric push rod, which is installed on the top of the moving plate 11. An extrusion plate is fixed on the output end of the electric push rod, and a stop block for blocking the large curved block is vertically fixed on the moving plate 11. In use, the large curved block is placed between the extrusion plate and the stop block, and the large curved block is clamped and fixed by the extrusion plate and the stop block.

[0026] The push plate 14 and the baffle 10 without bolts 15 are provided with anti-slip textures to increase the friction with the large curved block. When the push plate 14 and the baffle 10 without bolts 15 clamp and fix the large curved block, the anti-slip textures can increase the friction between the push plate 14 and the baffle 10 and the large curved block respectively, preventing the large curved block from slipping during sampling.

[0027] To elaborate further, such as Figure 1 , Figure 3 and Figure 4As shown, this embodiment preferably includes a threaded rod 16. A threaded hole is provided on the base plate 12, which is vertically connected and threadedly engaged with the threaded rod 16. The threaded rod 16 passes through the threaded hole, with its upper end resting on the moving plate 11. A handle 13 is fixed to the lower end of the threaded rod 16. By rotating the handle 13, the threaded rod 16 is driven to rotate, and the threaded rod 16 moves upward through the threaded engagement with the threaded hole, causing the threaded rod 16 to push the moving plate 11 upward. Conversely, when the handle 13 drives the threaded rod 16 to rotate in the opposite direction, the threaded rod 16 moves downward, and the moving plate 11 moves downward by its own weight and that of the large curved block. This solution constitutes a moving assembly for driving the moving plate 11 to move up and down. Alternatively, the moving assembly can also use an electric push rod, which is vertically positioned between the moving plate 11 and the base plate 12. The telescopic end of the electric push rod is fixed to the bottom of the moving plate 11, and the fixed end is fixed to the top of the base plate 12. The telescopic movement of the electric push rod drives the moving plate 11 to move up and down.

[0028] A mounting box 9 is horizontally arranged above the movable plate 11. The opening of the mounting box 9 faces upward, and the top is fixed with a box cover that seals the opening by screws.

[0029] A sampling tube 8 is vertically and independently passed through the mounting box 9. The top and bottom of the mounting box 9 have through holes aligned with the axis. The sampling tube 8 passes through the two through holes. The two ends of the sampling tube 8 are located outside the mounting box 9. There are gaps between all the through holes and the sampling tube 8, so that the sampling tube 8 can rotate.

[0030] Two positioning rings 7 are fitted on the sampling tube 8, which respectively fit the inner top and inner bottom of the mounting box 9. The two positioning rings 7 can limit the sampling tube 8, prevent the sampling tube 8 from moving up and down, and prevent the sampling tube 8 from falling out of the mounting box 9.

[0031] The bottom of the sampling tube 8 is equipped with several cutting teeth. The number of cutting teeth can be selected according to the actual use. All cutting teeth are evenly fixed at the bottom of the sampling tube 8 along the circumference. The moving plate 11 drives the large curved block to move upward and fit against the bottom of the sampling tube 8. When the sampling tube 8 rotates, it will drive all the cutting teeth to rotate and cut the large curved block. The part of the large curved block that is in contact with the cutting teeth will be cut into small fragments, which will not cause excessive damage to the overall structure of the large curved block. This can avoid excessive material waste, reduce waste generation, and save time and labor costs in subsequent processing. The uncut part located in the middle of all the cutting teeth... The large curvature block is a sample block, which will be stored inside the sampling tube 8. The moving plate 11 continues to move upward, so that the sampling tube 8 continues to advance towards the large curvature block until the large curvature block is penetrated. The sample block will be stuck inside the sampling tube 8 and can be pushed out from the inside of the sampling tube 8 with a stick, thereby obtaining the required large curvature block sample. When cutting the large curvature block through the cutting teeth on the sampling tube 8, the cutting speed of the cutting teeth can be adjusted by controlling the upward movement speed of the moving plate 11 to avoid excessive compression and friction between the internal material of the large curvature block and the cutting teeth, and to avoid the temperature rise at the cutting point. At the same time, an appropriate rotation speed is selected to ensure that the heat generated during the cutting process is within a controllable range.

[0032] The outer wall of the sampling tube 8 is provided with several chip discharge grooves for discharging cutting debris. Each chip discharge groove is connected to the groove between two adjacent cutting teeth. The debris cut by the cutting teeth can be discharged through the chip discharge grooves to the sampling hole, avoiding excessive debris accumulation that would affect the cutting effect, and also avoiding excessive debris accumulation in the sampling hole that would cause friction and heat generation.

[0033] To elaborate further, such as Figure 1 and Figure 4As shown, this embodiment preferably includes two meshing bevel gears 5. A motor 4 is mounted on the mounting box 9, with the output end of the motor 4 passing through the box wall and located inside the mounting box 9. One bevel gear 5 is fitted onto the output end of the motor 4, and the other bevel gear 5 is fitted onto the sampling tube 8. The motor 4 is mounted on the side wall of the mounting box 9 by screws. In use, the motor 4 is started, which drives the fixed bevel gear 5 to rotate. This bevel gear 5 drives the other bevel gear 5 to rotate, allowing the sampling tube 8 to rotate. The motor 4 is an existing product. When using a DC motor, it can be replaced with an automatic transformer, resistor, inductor, or other suitable components. The speed of the motor can be changed by using containers or other equipment. When using an AC motor, the speed can be changed by a frequency converter. These methods of changing the motor speed are common knowledge and will not be elaborated here. The speed of the sampling tube 8 is adjusted by adjusting the speed of the motor 4. The whole solution constitutes a drive assembly for driving the sampling tube 8 to rotate. Of course, the drive assembly can also be a crank. The crank has an L-shaped structure. The horizontal end of the crank is fixed to the side wall of the sampling tube 8, and the vertical end is facing upward. When in use, the user holds the vertical end of the crank and rotates it around the sampling tube 8, thereby driving the sampling tube 8 to rotate. The faster the user shakes the crank, the faster the sampling tube 8 rotates.

[0034] To elaborate further, such as Figure 1 , Figure 2 and Figure 4 As shown, this embodiment preferably includes two guide rods 3. The tops of the two support rods 1 are horizontally fixed with mounting plates 2. The two ends of the two guide rods 3 are respectively fixed to the two mounting plates 2. The two guide rods 3 are aligned with a front-to-back gap. Movable sleeves 6 are independently fitted onto each of the two guide rods 3. All movable sleeves 6 are fixed to the top of the mounting box 9. The mounting box 9 is supported by the two guide rods 3. One of the movable sleeves 6 has a threaded hole with internal and external connections. A screw with a threaded fit is inserted into the threaded hole, with one end of the screw pressing against the inner guide rod 3. In use, pushing the mounting box 9 causes the two movable sleeves 6 to move along the corresponding guide rods 3, thus moving left and right. Adjust the position of the mounting box 9 so that the sampling tube 8 can move left and right to align with different positions on the large curved block, thereby collecting samples from different positions on the large curved block. When the sampling tube 8 is aligned with the designated position on the large curved block, rotate the screw so that one end of the screw abuts against the corresponding guide rod 3, thereby locking the moved mounting box 9. This scheme constitutes a support assembly for supporting and adjusting the left and right movement of the mounting box 9. Of course, the support assembly can also be a horizontal plate, with both ends of the horizontal plate fixed to two support rods 1. A sliding groove is provided at the bottom of the horizontal plate, and a slider that can move left and right along the groove is engaged in the sliding groove. The mounting box 9 is fixed to the slider, and a screw for locking the slider after movement is installed on the slider.

[0035] In actual use, the large curved block is placed on top of the moving plate 11, between the two baffles 10. The position of the large curved block on the moving plate 11 is adjusted. By rotating the bolt 15, the bolt 15 pushes the push plate 14 towards the large curved block. The push plate 14 pushes the large curved block to fit against the baffle 10 on the right side, so that the push plate 14 and the baffle 10 on the right side clamp and fix the large curved block. Then, the mounting box 9 is pushed, causing the mounting box 9 to move the two moving sleeves 6 along the corresponding guide rods 3. The position of the mounting box 9 is adjusted left and right to align the sampling tube 8 with the predetermined position on the large curved block. Then, the screw is turned so that one end of the screw presses against the corresponding guide rod 3 to lock the mounting box 9 and lock the position of the sampling tube 8. Then, the motor 4 is started, which drives the bevel gear 5 fixed to it to rotate. This bevel gear 5 drives another bevel gear 5 to rotate, so that the sampling tube 8 can rotate. Then, the handle 13 is turned to drive the threaded rod 16 to rotate. The threaded rod 16 moves upward through the threaded engagement with the threaded hole. The movement causes the threaded rod 16 to push the moving plate 11 upward, which in turn moves the large curved block on it upward and makes it fit against the bottom of the sampling tube 8. When the sampling tube 8 rotates, it will cause all the cutting teeth to rotate and cut the large curved block. The part of the large curved block that is in contact with the cutting teeth will be cut into small fragments, which will not cause too much damage to the overall structure of the large curved block. This will avoid excessive material waste, reduce waste generation, and save time and labor costs in subsequent processing. The uncut part of the large curved block located in the middle of all the cutting teeth is the sample block, which will be stored in the sampling tube 8. The moving plate 11 continues to move upward, causing the sampling tube 8 to continue to cut towards the large curved block until it penetrates the large curved block. The sample block will then be stuck in the sampling tube 8. Then, the handle 13 is rotated in the opposite direction, causing the moving plate 11 to move the large curved block downward, allowing the sampling tube 8 to be pulled out from the sampling hole on the large curved block. Then, the sample block is pushed out from the inside of the sampling tube 8 by a stick, thus obtaining the required large curved block sample.
