Description

Technical Field

[0001] The invention relates to the technical field of brine product detection and sampling, and in particular to a brine sampling device for hygienic and safe detection of brine product processing. Background Art

[0002] Brine, also known as marinade, is used to make various types of marinated dishes. It is a liquid substance made from various edible spices. In the process of industrialized marinated products processing and production, it is necessary to regularly take random samples of the brine used to make marinated products and test its moisture content, acid value and peroxide value, heavy metal content and microbial indicators to ensure that it meets national food hygiene standards and meets the health needs of consumers.

[0003] In the existing brine sampling process, a sampling tube is manually held and placed into a brine storage container to collect brine, which is then poured into the sample storage container of the sampling box. Since it is difficult to manually control the brine collection capacity accurately during the sampling process, the sampling tube obtains less brine or is too full. As a result, in the process of filling the sample storage container with brine, if the capacity of a single collection is not enough, multiple collections are required, which increases repeated operation steps and delays the working time. If the capacity of a single collection is large, on the one hand, the brine in the sampling tube is easy to spill onto the ground during the transfer process and when pouring it into the sample storage container, increasing the subsequent cleaning of the scene. On the other hand, after the sample storage container is full, the remaining brine in the sampling tube needs to be poured back into the brine storage container again, adding unnecessary work steps, which results in the brine sampling work being not clean, neat, convenient and efficient enough. Summary of the invention

[0004] In view of the problem that it is difficult to accurately control the extraction capacity during the brine sampling process in the prior art, a brine sampling device for hygienic and safe testing of brine product processing is proposed.

[0005] The purpose is to reduce the volume of the cylinder by deforming the rubber sheet upwards, and to return the rubber sheet to its original position after the cylinder is filled with brine, so that a certain amount of brine is stored in the cylinder.

[0006] The technical solution of the present invention is a brine sampling device for hygienic and safe detection of brine product processing, comprising a base, and also comprising a plurality of rotating brackets installed on the base, wherein the plurality of rotating brackets are arranged in a ring-shaped manner with equal spacing, and a sampling mechanism is connected to one end of the rotating bracket, and an operating rod that can move vertically is provided on the base, and the operating rod is used to drive the rotating bracket to rotate; the sampling mechanism comprises a sampling barrel movably connected to the rotating bracket, and a capacity regulating component arranged in the sampling barrel, wherein the sampling barrel comprises a barrel body, a barrel cover, and a valve plate, and the barrel body is threadedly connected to the barrel cover , a plurality of through holes are provided on the cylinder cover, the valve plate is in abutment with the cylinder cover, the capacity regulating component includes a rubber sheet connected and fixed to the cylinder body, the rubber sheet is in a funnel-shaped structure, and the rubber sheet is connected to the valve plate; the rotating bracket includes a connecting rod movably connected to the cylinder cover, two extension rods are fixedly connected to the connecting rod, one end of the extension rod is hinged with a rotating rod, the two rotating rods are arranged in a parallelogram structure, one end of the rotating rod is hinged with the base, and one of the rotating rods is fixedly connected with a pull rope, and the pull rope is used to drive the valve plate and the rubber sheet to move.

[0007] By adopting the above technical scheme, when the operating rod moves upward, it can drive one of the rotating brackets to rotate, and the two rotating rods rotate synchronously, so that the sampling tube follows the rotating bracket to rotate to a position lower than the base. At the same time, the pull rope drives the valve plate to rise, and drives the rubber sheet to move upward, so that the tip of the rubber sheet is set upward. At this time, the internal volume of the cylinder is reduced, and the sampling tube is immersed in the brine storage container to allow the brine to enter the cylinder through the through hole. After the cylinder is full, when the rotating bracket rotates in the opposite direction to drive the sampling tube to rise, the valve plate descends and fits with the cylinder cover, and at the same time, the rubber sheet moves downward, so that the tip of the rubber sheet is set downward. At this time, the internal volume of the cylinder increases, and the brine level is lower than the cylinder port, which can avoid brine overflow and enable the cylinder to quickly obtain a quantitative amount of brine.

[0008] Furthermore, the base includes two vertically arranged bottom plates 1, a handle is fixedly connected to the top of the upper bottom plate 1, a plurality of partitions are fixedly connected in a circular shape with equal intervals between the two bottom plates 1, and a bottom plate 2 is fixedly connected between the plurality of partitions; a protective cover is provided on the base.

[0009] By adopting the above technical solution, two adjacent partitions and a bottom plate are used in a space, and the sampling tube and the rotating bracket connected thereto are arranged in the space. When the rotating bracket is arranged vertically, the sampling tube is arranged between the two bottom plates. At this time, the protective cover can be inserted from the top of the base downward to provide safety protection for the base and its internal structure.

[0010] Furthermore, the cylinder cover is of a conical structure, and a connecting seat is fixedly connected to the cylinder cover, a sliding column is slidably connected in the connecting seat, and the sliding column is fixedly connected to the valve plate.

[0011] By adopting the above technical solution, the sliding column drives the valve plate to move synchronously when sliding up and down in the connecting seat. A sealing gasket is fixed on the side of the valve plate facing the cylinder cover. When the sealing gasket abuts against the cylinder cover, the through hole can be closed to prevent liquid from overflowing.

[0012] Furthermore, the rubber sheet is arranged in the lower part of the cylinder, the bottom of the rubber sheet is elastically connected to the cylinder through a spring, the rubber sheet is fixedly connected to a pull rod, the pull rod is slidably arranged in the cylinder, and one end of the pull rod is connected to the sliding column.

[0013] By adopting the above technical solution, the tip of the rubber sheet is set downward under the action of spring 1, at which time the cylinder and the rubber sheet cooperate to form the maximum volume. When the sliding column drives the pull rod to rise, the tip of the rubber sheet is set upward, at which time the cylinder and the rubber sheet cooperate to form the minimum volume.

[0014] Furthermore, connecting parts are provided at both ends of the sliding column, and the connecting parts include a T-shaped rod and a connecting block. The connecting block is provided with a T-shaped groove that is compatible with the T-shaped rod. The upper connecting block is slidably arranged in the connecting rod and is connected and fixed to the pull rope, and the lower connecting block is connected and fixed to the pull rod.

[0015] By adopting the above technical solution, one end of the T-shaped rod is inserted into the T-shaped groove and rotated at a certain angle, so that the one end of the T-shaped rod is connected to the connecting block. When the rotating rod rotates to the horizontal state, the connecting block connected to it is driven to rise by the pull rope, so that the sliding column rises. At this time, the valve plate rises, so that the through hole of the cylinder cover is in an open state. At the same time, the pull rod rises with the sliding column, so that the tip of the rubber sheet is set upward. At this time, the cylinder body and the rubber sheet cooperate to form a minimum volume.

[0016] Furthermore, the connecting rod is sleeve-engaged with the connecting seat, and a plurality of positioning blocks are fixedly connected to the lower end of the connecting rod, and an L-shaped groove matched with the positioning block is provided in the connecting seat.

[0017] By adopting the above technical solution, the positioning block slides down to the bottom along the vertical part of the L-shaped groove and rotates counterclockwise by a certain angle, so that the connecting seat and the connecting rod are stably connected, and quick disassembly is achieved, which facilitates the disassembly and cleaning of the sampling tube after use.

[0018] Furthermore, the operating rod includes a T-shaped rod 2 movably connected to the base plate 1, a pointer is fixedly connected to the upper end of the T-shaped rod 2, and an arc-shaped rack is fixedly connected to the lower end of the T-shaped rod 2, and the arc-shaped rack is in transmission cooperation with the rotating bracket.

[0019] By adopting the above technical solution, an indicator arrow is engraved on the top surface of the upper bottom plate 1 at the position corresponding to the sampling barrel, and the T-shaped rod 2 can rotate and slide up and down between the two bottom plates 1. When the T-shaped rod 2 is rotated so that the pointer points to one of the indicator arrows, the arc-shaped rack is arranged below the sampling barrel below the indicator arrow. When the T-shaped rod 2 is driven to rise vertically, the arc-shaped rack cooperates with the corresponding rotating bracket to drive the rotating bracket to rotate, so that the sampling barrel rotates downward and leaves the base.

[0020] Furthermore, the rotating rod away from the operating rod side is hinged to the lower bottom plate, and a spring 2 is elastically connected between the rotating rod and the bottom plate 2. The rotating rod close to the operating rod side is hinged to the bottom plate 2, and a gear is fixedly connected to the lower end of the rotating rod, and the gear is meshed with the arc-shaped rack for transmission.

[0021] By adopting the above technical scheme, the gear axis coincides with the rotation axis of the lower end of the rotating rod. When the T-shaped rod two rises vertically, the arc-shaped rack engages with the corresponding gear, thereby driving the rotating rod to rotate. Since the two rotating rods are arranged in a parallelogram and the lower end of the rotating rod is hinged to the base, the connecting rod and the sampling barrel itself can be driven to make a semicircular movement as a whole while maintaining a vertical state, thereby driving the sampling barrel to rotate to a position lower than the base. By holding the handle, the sampling barrel can be inserted into the brine for brine sampling. During the process of the rotating rod rotating to the horizontal state, the spring two is stretched and stored. When the T-shaped rod two descends, the spring two contracts and drives the rotating rod to rotate in the opposite direction and reset.

[0022] Furthermore, a liquid collecting assembly is provided at the bottom of the cylinder, and the liquid collecting assembly includes a liquid collecting cup with a concave structure, and a plurality of rubber pads are fixedly connected to the upper part of the liquid collecting cup in a ring-shaped manner with equal intervals, and the rubber pads are abutted against the cylinder, and the top of the rubber pads is in a triangular structure, and an anti-overflow ring is fixedly connected to the lower part of the liquid collecting cup, and the liquid collecting cup is provided with a plurality of reflux holes at the anti-overflow ring.

[0023] By adopting the above technical scheme, the diameter of the circular cavity formed by multiple rubber pads is smaller than the diameter of the cylinder. The diameter of the circular cavity can be increased by the deformation of the rubber pads, so that the liquid collecting cup can be engaged with the bottom of the cylinder. After the sampling cylinder leaves the brine storage container, a small amount of brine will adhere to its outer surface. The brine flows downward along the surface of the cylinder and can flow into the groove of the liquid collecting cup through the gap between two adjacent rubber pads. At the same time, the bottom of the liquid collecting cup is conically arranged, so that the brine at the bottom flows along the inclined surface to the anti-overflow ring and flows into the groove of the liquid collecting cup through the reflux hole.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the rotating bracket drives the sampling tube to move downward, the pull rope drives the valve plate to leave the tube cover and drives the tip of the rubber sheet to move upward, thereby reducing the internal volume of the tube. When the tube is filled with brine and the rotating bracket rotates in the opposite direction, the valve plate abuts against the tube cover and the tip of the rubber sheet is set downward, thereby increasing the internal volume of the tube. At this time, the brine level is lower than the port of the tube, thereby achieving rapid acquisition of quantitative brine while avoiding brine overflow, making brine sampling simple and efficient.

[0026] 2. The brine adhered to the surface of the cylinder can flow into the collecting cup under the guidance of the rubber pad. At the same time, the brine adhered to the bottom of the collecting cup can flow along the inclined surface to the anti-overflow ring and flow into the collecting cup through the reflux hole. When the sampling cylinder leaves the brine storage container, the brine on the outer surface is collected by the collecting cup to prevent the brine from dripping.

[0027] 3. The rotation and lifting of the operating lever can control the independent movement of each sampling tube, so as to realize the classified storage of different brines. At the same time, the quick-release design of the connecting rod and the connecting seat can be used to quickly remove the sampling tube, which is convenient for taking out the brine and cleaning the sampling tube.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] Example 1, reference Figure 1-Figure 10 , which is the first embodiment of the present invention, provides a brine sampling device for hygienic and safe detection of brine products processing, including a base 1, and also including a plurality of rotating brackets 4 installed on the base 1, the plurality of rotating brackets 4 are arranged in a ring with equal intervals, one end of the rotating bracket 4 is connected to a sampling mechanism, and a vertically movable operating rod 6 is provided on the base 1, and the operating rod 6 is used to drive the rotating bracket 4 to rotate; the sampling mechanism includes a sampling barrel 2 movably connected to the rotating bracket 4, and a capacity regulating component 3 arranged in the sampling barrel 2, the sampling barrel 2 includes a barrel body 201, a barrel cover 202, and a valve plate 203, the barrel body 201 is threadedly connected to the barrel cover 202, and the barrel cover 202 is provided with a plurality of Through hole, the valve plate 203 is abutted with the cylinder cover 202, the capacity regulating component 3 includes a rubber sheet 301 connected and fixed to the cylinder body 201, the rubber sheet 301 is a funnel-shaped structure, and the rubber sheet 301 is connected to the valve plate 203; the rotating bracket 4 includes a connecting rod 401 movably connected to the cylinder cover 202, two extension rods 402 are fixedly connected to the connecting rod 401, one end of the extension rod 402 is hinged with a rotating rod 403, the two rotating rods 403 are arranged in a parallelogram structure, one end of the rotating rod 403 is hinged with the base 1, and one of the rotating rods 403 is fixedly connected with a pull rope 404, the pull rope 404 is used to drive the valve plate 203 and the rubber sheet 301 to move.

[0043] Specifically, when the operating rod 6 moves upward, it can drive one of the rotating brackets 4 to rotate, and the two rotating rods 403 rotate synchronously, so that the sampling tube 2 follows the rotating bracket 4 to rotate to a position lower than the base 1. At the same time, the pull rope 404 drives the valve plate 203 to rise, and drives the rubber sheet 301 to move upward, so that the tip of the rubber sheet 301 is set upward. At this time, the internal volume of the cylinder 201 is reduced, and the sampling tube 2 is immersed in the brine storage container so that the brine enters the cylinder 201 through the through hole. After the cylinder 201 is full, when the rotating bracket 4 rotates in the opposite direction to drive the sampling tube 2 to rise, the valve plate 203 descends and fits with the cylinder cover 202. At the same time, the rubber sheet 301 moves downward, so that the tip of the rubber sheet 301 is set downward. At this time, the internal volume of the cylinder 201 increases, and the brine level is lower than the port of the cylinder 201, which can avoid brine overflow and enable the cylinder 201 to quickly obtain a certain amount of brine.

[0044] Reference Figure 2-Figure 3 The base 1 includes two vertically arranged bottom plates 101, a handle is fixedly connected to the top of the upper bottom plate 101, a plurality of partitions 102 are fixedly connected to the two bottom plates 101 in a circular shape with equal intervals, and a bottom plate 2 103 is fixedly connected between the plurality of partitions 102; a protective cover 7 is provided on the base 1.

[0045] Specifically, two adjacent partitions 102 cooperate with the bottom plate 101 to form a space, and the sampling tube 2 and the rotating bracket 4 connected thereto are arranged in the space. When the rotating bracket 4 is vertically arranged, the sampling tube 2 is arranged between the two bottom plates 101. At this time, the protective cover 7 can be inserted from the top of the base 1 downward, so that the protective cover 7 provides safety protection for the base 1 and its internal structure.

[0046] When the rotating bracket 4 rotates, the sampling tube 2 as a whole makes a circular motion, and a clearance hole is opened on the lower bottom plate 101 at a position corresponding to the sampling tube 2 to facilitate the movement of the sampling tube 2.

[0047] Reference Figure 6 , Figure 8 The cylinder cover 202 has a conical structure, and a connecting seat 204 is fixedly connected to the cylinder cover 202 , a sliding column 205 is slidably connected in the connecting seat 204 , and the sliding column 205 is fixedly connected to the valve plate 203 .

[0048] Specifically, when the sliding column 205 slides up and down in the connecting seat 204, it drives the valve plate 203 to move synchronously. A sealing gasket is fixedly arranged on the side of the valve plate 203 facing the cylinder cover 202. When the sealing gasket abuts against the cylinder cover 202, the through hole can be closed to prevent liquid from overflowing.

[0049] Reference Figure 7The rubber sheet 301 is arranged at the lower part of the cylinder 201, and the bottom of the rubber sheet 301 is elastically connected to the cylinder 201 through a spring 302. The rubber sheet 301 is fixedly connected to a pull rod 303, and the pull rod 303 is slidably arranged in the cylinder 201, and one end of the pull rod 303 is connected to the sliding column 205.

[0050] Specifically, the tip of the rubber sheet 301 is set downward under the action of the spring 1 302. At this time, the cylinder 201 and the rubber sheet 301 cooperate to form the maximum volume. When the sliding column 205 drives the pull rod 303 to rise, the tip of the rubber sheet 301 is set upward. At this time, the cylinder 201 and the rubber sheet 301 cooperate to form the minimum volume.

[0051] Reference Figure 8 , Fig. 9 Both ends of the sliding column 205 are provided with connecting parts 5, and the connecting parts 5 include a T-shaped rod 501 and a connecting block 502. The connecting block 502 is provided with a T-shaped slot 503 adapted to the T-shaped rod 501. The upper connecting block 502 is slidably arranged in the connecting rod 401 and is connected and fixed to the pull rope 404. The lower connecting block 502 is connected and fixed to the pull rod 303.

[0052] Specifically, after the end of the T-shaped rod 501 passes through the T-shaped slot 503 and rotates a certain angle, one end of the T-shaped rod 501 is connected to the connecting block 502. When the rotating rod 403 rotates to a horizontal state, the connecting block 502 connected to it is driven to rise through the pull rope 404, so that the sliding column 205 rises. At this time, the valve plate 203 rises, so that the through hole of the cylinder cover 202 is in an open state. At the same time, the pull rod 303 rises with the sliding column 205, so that the tip of the rubber sheet 301 is set upward. At this time, the cylinder body 201 and the rubber sheet 301 cooperate to form a minimum volume.

[0053] Among them, refer to Figure 5 , Figure 8 When the rotating rod 403 is in a vertical state, one end of the pull rope 404 passes through the connecting rod 401 and extends downward. The right part of the pull rope 404 forms a triangular structure with an extension rod 402 and the rotating rod 403. When the rotating rod 403 rotates to a horizontal state, the pull rope 404 moves to the right as a whole, driving the connecting block 502 connected thereto to rise.

[0054] Reference Figure 1 , Fig.10 The operating rod 6 includes a T-shaped rod 601 movably connected to the bottom plate 101, a pointer 602 is fixedly connected to the upper end of the T-shaped rod 601, and an arc-shaped rack 603 is fixedly connected to the lower end of the T-shaped rod 601, and the arc-shaped rack 603 is transmission-coordinated with the rotating bracket 4.

[0055] Specifically, an indicating arrow is engraved on the top surface of the upper bottom plate 101 at a position corresponding to the sampling tube 2, and the T-shaped rod 601 can rotate and slide up and down between the two bottom plates 101. When the T-shaped rod 601 is rotated so that the pointer 602 points to one of the indicating arrows, the arc-shaped rack 603 is arranged below the sampling tube 2 below the indicating arrow. When the T-shaped rod 601 is driven to rise vertically, the arc-shaped rack 603 cooperates with the corresponding rotating bracket 4 to drive the rotating bracket 4 to rotate, so that the sampling tube 2 rotates downward and leaves the base 1.

[0056] Reference Figure 4 , Figure 5 , Fig.10 The rotating rod 403 on the side away from the operating rod 6 is hinged to the lower bottom plate 101, and a spring 2 406 is elastically connected between the rotating rod 403 and the bottom plate 2 103. The rotating rod 403 on the side close to the operating rod 6 is hinged to the bottom plate 2 103, and a gear 407 is fixedly connected to the lower end of the rotating rod 403, and the gear 407 is meshed with the arc rack 603 for transmission.

[0057] Specifically, the axis of the gear 407 coincides with the axis of rotation of the lower end of the rotating rod 403. When the T-shaped rod 601 rises vertically, the arc-shaped rack 603 engages with the corresponding gear 407, thereby driving the rotating rod 403 to rotate. Since the two rotating rods 403 are arranged in a parallelogram and the lower end of the rotating rod 403 is hinged to the base 1, the connecting rod 401 and the sampling barrel 2 can be driven to make a semicircular movement as a whole while maintaining a vertical state, thereby driving the sampling barrel 2 to rotate to a position lower than the base 1. By holding the handle, the sampling barrel 2 can be placed in the brine for brine sampling. During the rotation of the rotating rod 403 to the horizontal state, the spring 406 is stretched and stored. When the T-shaped rod 601 descends, the spring 406 contracts and drives the rotating rod 403 to rotate in the opposite direction and reset.

[0058] Among them, refer to Figure 5 In order to realize that the two rotating rods 403 are arranged in a parallelogram shape, the two extension rods 402 are vertically connected to the connecting rod 401, and the lengths of the two extension rods 402 are different. The longer extension rod 402 is hinged to the rotating rod 403 on the side close to the operating rod 6, and the shorter extension rod 402 is hinged to the rotating rod 403 on the side away from the operating rod 6.

[0059] Example 2, reference Figure 5 , Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the connecting rod 401 is sleeved and matched with the connecting seat 204, and a plurality of positioning blocks 405 are fixedly connected to the lower end of the connecting rod 401, and an L-shaped groove 206 adapted to the positioning block 405 is opened in the connecting seat 204.

[0060] Specifically, the positioning block 405 slides down to the bottom along the vertical portion of the L-shaped groove 206 and rotates counterclockwise by a certain angle, so that the connection seat 204 and the connecting rod 401 are stably connected and quickly disassembled, so that the sampling tube 2 can be disassembled and cleaned after use. The rest of the structure is the same as that of Example 1.

[0061] Example 3, reference Figure 4 , Fig.11 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a liquid collecting component 8 is arranged at the bottom of the cylinder 201, and the liquid collecting component 8 includes a liquid collecting cup 801 with a concave structure. A plurality of rubber pads 802 are fixedly connected to the upper part of the liquid collecting cup 801 in a ring-shaped manner and at equal intervals. The rubber pad 802 abuts against the cylinder 201, and the top of the rubber pad 802 is in a triangular structure. An anti-overflow ring 803 is fixedly connected to the lower part of the liquid collecting cup 801, and a plurality of reflux holes are opened in the liquid collecting cup 801 at the anti-overflow ring 803.

[0062] Specifically, the diameter of the circular cavity formed by the multiple rubber pads 802 is smaller than the diameter of the cylinder 201. The diameter of the circular cavity can be increased by the deformation of the rubber pads 802, so that the liquid collecting cup 801 can be engaged with the bottom of the cylinder 201. After the sampling tube 2 leaves the brine storage container, a small amount of brine will adhere to its outer surface. The brine flows downward along the surface of the cylinder 201 and can flow into the groove of the liquid collecting cup 801 through the gap between two adjacent rubber pads 802. At the same time, the bottom of the liquid collecting cup 801 is conical, so that the brine at the bottom flows along the inclined surface to the anti-overflow ring 803 and flows into the groove of the liquid collecting cup 801 through the reflux hole.

[0063] It is understandable that the gap between two adjacent rubber pads 802 and the size of the reflux hole are small to prevent the brine in the brine storage container from quickly passing through the gap and the reflux hole and entering the liquid collection cup 801 when the sampling tube 2 is immersed in the brine. The rest of the structure is the same as that of Example 2.

[0064] In summary, the working principle of the present invention is as follows: hold the handle and rotate the T-shaped rod 601 to make the pointer 602 point to one of the indicating arrows, then drive the T-shaped rod 601 to rise vertically, the arc-shaped rack 603 engages with the corresponding gear 407, drives the rotating rod 403 to rotate, and the two rotating rods 403 rotate synchronously to a horizontal state, driving the sampling tube 2 to rotate downward to a position lower than the base 1. During this process, the pull rope 404 drives the sliding column 205 to rise, and the valve plate 203 moves toward the top of the tube cover 202, so that the through hole of the tube cover 202 is in an open state, and at the same time, the pull rod 303 is pulled along As the slide column 205 rises, the tip of the rubber sheet 301 is set upward. At this time, the cylinder 201 and the rubber sheet 301 cooperate to form a minimum volume. After the sampling cylinder 2 is put into the brine, the brine enters the cylinder 201 through the through hole. After the cylinder 201 is full, the T-shaped rod 601 is lowered, and the spring 406 contracts to drive the rotating rod 403 to rotate in the opposite direction to reset the sampling cylinder 2 to the base 1. During this process, the spring 302 drives the tip of the rubber sheet 301 to move downward, so that the internal volume of the cylinder 201 increases. At the same time, the valve plate 203 descends to close the through hole, thereby completing the quantitative sampling of the brine.
