Description

Technical Field

[0001] The invention belongs to the technical field of biological sample processing, and in particular relates to a method and a device for weighing fish tissue samples. Background Art

[0002] At present, when weighing fish tissue samples, ordinary electronic balances are often used in combination with simple holding containers for weighing. There are many types of existing electronic balances. Among them, in the existing public document, CN220288757U-electronic balance, a balance body is publicly provided, and a barrier for blocking strong acid or strong alkali liquid from splashing onto the display screen surface is provided between the weighing platform of the balance body and the display screen surface. And in the existing public document, CN220829276U-adjustable level electronic balance, an electronic balance body is publicly provided, the bottom end of the electronic balance body is provided with a telescopic support leg with adjustable length, the front end of the electronic balance body is provided with a horizontal bubble, the telescopic support legs are all movably installed on the bottom end of the electronic balance body through a position adjustment component, the position adjustment component is used to adjust the position of the telescopic support leg and the center of the electronic balance body, the position adjustment component includes a slide groove, a slider and a linear drive member that drives the slider to slide along the length direction of the slide groove, and the top of the telescopic support leg is fixedly connected to the bottom end of the slider.

[0003] Although the electronic balances in the above-mentioned existing documents can be used to weigh fish tissue samples, the existing electronic balances, when used to weigh fish tissue samples, mostly rely on manual placement of weighing cups for weighing, which is prone to placement position deviation, affecting the accuracy of weighing, and it is necessary to place the weighing cup on the weighing plate and take it out from the weighing plate many times, which is inefficient. In addition, the existing electronic balances have relatively single functions and cannot well meet the needs of various experimental weighing scenarios such as weighing the same or different fish tissue samples at one time. Usually, the existing electronic balances often only have basic weighing functions, and when not in use, the existing electronic balances need to place the weighing cups on an external storage rack similar to a test tube rack for storage. In addition, when sampling different fish tissue samples, the samples that are easily stuck on the tweezers are inconvenient to clean, resulting in mutual contamination between different samples, affecting the reliability of subsequent weighing and analysis results. To this end, we provide a method and device for weighing fish tissue samples to solve the above problems. Summary of the invention

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0050] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The present invention is a weighing device for fish tissue samples, comprising an electronic balance 100, a shield 200, a placing rack 300, a cup holder 400 and a weighing cup 500. The shield 200 is placed on the top of the electronic balance 100, and the placing rack 300 is inserted inside the shield 200. The placing rack 300 comprises a frame body 310, a motor 320 and a top seat 330. The motor 320 is fixed to the bottom surface of the top plate of the frame body 310, and the output shaft of the motor 320 is connected to the top seat 330. A group of annularly distributed cup holders 400 are fixed at the bottom of the placing rack 300. The cup holder 400 comprises a lateral moving component 410, a longitudinal hydraulic Rod 420 and cup holder 430, one side of the lateral moving component 410 is connected to the longitudinal hydraulic rod 420, the bottom of the longitudinal hydraulic rod 420 is connected to the cup holder 430, and the weighing cup 500 is inserted in the cup holder 430; the lateral moving component 410 includes a No. 1 connecting seat 411, a lateral hydraulic rod 412 and a No. 2 connecting seat 413, the No. 1 connecting seat 411 is fixed to the bottom of the top plate of the top seat 330 by screws, the lateral hydraulic rod 412 is inserted inside the No. 1 connecting seat 411 and locked by bolts, and a weighing cup 500 is placed on each cup holder 400, and a take-up plate 510 is placed inside the weighing cup 500.

[0051] Specifically, a frame 110 is fixed to the edge of the top surface of the electronic balance 100, and a weighing pan 120 is installed in the middle position of the top surface of the electronic balance 100; the protective cover 200 includes a cover body 210 and a door panel 220, the front and back of the cover body 210 are both glass plates, and the two side surfaces of the cover body 210 are slidably connected to the door panels 220.

[0052] Furthermore, a circular groove 201 is provided at the center of the top panel of the cover body 210, and column holes 202 are provided at the four corners of the top panel of the cover body 210. The bottom surface of the cover body 210 is a frame plate; a second touch screen 311 is fixed on the top surface of the top panel of the frame body 310, and a group of annularly distributed slide grooves 331 are provided on the bottom surface of the top seat 330. Each column of the frame body 310 is respectively inserted into each column hole 202, and the top panel of the frame body 310 is placed on the top surface of the circular groove 201; the second connection An L-shaped seat plate 4131 is fixed on the side plate of the seat 413, and a slider 4132 is fixed on the top of the L-shaped seat plate 4131. The size of the slider 4132 matches the size of the slide groove 331, and the slider 4132 is slidably connected in the corresponding slide groove 331; the longitudinal hydraulic rod 420 is inserted into the interior of the second connecting seat 413 and locked by bolts, and a connecting plate 431 is fixed on the top surface of the cup seat 430, and the output shaft of the longitudinal hydraulic rod 420 is connected to the connecting plate 431.

[0053] The operation process of this embodiment is as follows: when in use, when the motor 320 is started, its output shaft drives the top seat 330 to rotate, and through the rotation of the motor 320, the cup holder 400 and the weighing cup 500 fixed below the top seat 330 are rotated, so that the weighing cups 500 at different positions are switched in front of the operator, which can assist in loading or unloading. When multiple weighing cups 500 need to be operated, there is no need to manually move too much to find the corresponding weighing cup 500, thereby improving the operation efficiency;

[0054] If the same fish tissue samples need to be weighed at one time, the placement rack 300 is pulled out and placed on the operating table, and then a weighing cup 500 is taken out and placed on the weighing plate 120 for "peeling", and then the fish tissue samples are clamped with tweezers 520 and placed in each weighing cup 500, and then the columns of the placement rack 300 are aligned with the column holes 202 and inserted, so that the columns of the placement rack 300 are supported on the top surface of the electronic balance 100;

[0055] Then, the transverse hydraulic rod 412 and the longitudinal hydraulic rod 420 of the first cup holder 400 are activated through the second touch screen 311. The second connecting seat 413 is driven to move inward as a whole through the action of the transverse hydraulic rod 412 until the longitudinal center axis of the cup holder 430 in the cup holder 400 coincides with the longitudinal center axis of the weighing pan 120. Then, the cup holder 430 of the cup holder 400 is driven to move downward as a whole through the action of the longitudinal hydraulic rod 420, so that the weighing cup 500 on the cup holder 400 is placed in the center of the weighing pan 120. At the center, the cup holder 430 of the cup rack 400 is still driven to move downward by the action of the longitudinal hydraulic rod 420, so that the cup holder 430 does not contact the top edge of the weighing pan 120, that is, the cup holder 430 does not contact the weighing pan 120, to prevent affecting the weighing result. When the cup holder 430 moves down to the preset position, the longitudinal hydraulic rod 420 stops immediately. At this time, the weighing pan 120 on the electronic balance 100 weighs the weight of the weighing cup 500. After the data value on the display screen of the electronic balance 100 is stable, the first weighing operation is completed.

[0056] After the weighing is completed, the transverse hydraulic rod 412 and the longitudinal hydraulic rod 420 of the first cup holder 400 are activated again through the second touch screen 311. The cup holder 430 of the cup holder 400 is driven to move upward to the original position as a whole through the action of the longitudinal hydraulic rod 420. Then, the second connecting seat 413 is driven to move outward to the original position as a whole through the action of the transverse hydraulic rod 412.

[0057] Then, the horizontal hydraulic rod 412 and the longitudinal hydraulic rod 420 of the second cup holder 400 are activated through the second touch screen 311 to complete the second weighing operation, and the weighing operation of the weighing cup 500 in each cup holder 400 is completed in a clockwise manner.

[0058] After the weighing of the weighing cup 500 on the first cup holder 400 is completed, the weighing cup 500 on the second cup holder 400 is replaced for weighing, and the operator can record the first weighing result, thus completing a recording operation;

[0059] In addition, the placement rack 300 can be pulled out separately for storing the weighing cups 500. When not in use, each weighing cup 500 can be placed on the placement rack 300, and then the placement rack 300 is inserted into the protective cover 200 for storage, thereby achieving the purpose of storage and dust prevention.

[0060] Furthermore, in normal weighing, the shielding effect of the protective cover 200 and the placement rack 300 can prevent a large amount of dust particles in the air from entering the weighing pan 120 of the balance, which is not likely to affect the measurement accuracy of the balance, thereby improving the measurement accuracy. Example 2

[0061] See also Figure 5 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 On the basis of Example 1, a group of symmetrical slots 511 are opened in the center of the strap 510, a rubber scraper 512 is fixed to the edge of the bottom of each slot 511, and tweezers 520 are inserted into the slots 511 of the strap 510.

[0062] Specifically, a slot 501 is provided on one side of the top surface of the weighing cup 500, and the size of the slot 501 matches the size of the connecting plate 431, and the connecting plate 431 crosses the corresponding slot 501; a group of annularly distributed L-shaped slots 502 are provided on the inner wall of the weighing cup 500, and the mounting blocks at each end of the mounting plate 510 are respectively inserted into each L-shaped slot 502.

[0063] Furthermore, the tweezers 520 include a handle 521 and a metal plate 522 . Metal plates 522 are fixed to both ends of the bottom of the handle 521 . The size of the metal plate 522 matches the size of the slot 511 . The slot 511 at the center of the mounting plate 510 is arranged in one-to-one correspondence with the metal plate 522 of the tweezers 520 .

[0064] The operation process of this embodiment is as follows: if different fish tissue samples need to be weighed at one time, firstly, the placement rack 300 is pulled out and placed on the operating table, then a weighing cup 500 is taken out and placed on the weighing plate 120 for "peeling", then one type of fish tissue sample is clamped with tweezers 520 and placed in a corresponding number of weighing cups 500, and then another type of fish tissue sample is clamped with tweezers 520 and placed in a corresponding number of weighing cups 500;

[0065] After loading, insert the placement rack 300 into the placement rack 300, and then perform weighing operations on each weighing cup 500 in sequence according to the same operation as above;

[0066] It should be added that when sampling, after sampling of one fish tissue sample is completed and the last weighing cup 500 of the fish tissue sample is sampled, the upper part of the two metal plates 522 in the tweezers 520 is directly inserted horizontally into the slot 511, and then the tweezers 520 are pulled upwards. The fish tissue sample stuck to the lower part of the two metal plates 522 in the tweezers 520 can be scraped clean through the rubber scraper 512 at the bottom of the slot 511, and then the tweezers 520 are used to sample another fish tissue sample. Example 3

[0067] See also Figure 1 , Figure 3 and Figure 4 On the basis of Embodiment 1 and Embodiment 2, a heating component 221 is fixed to the inner side of the door panel 220 , and a touch screen No. 1 222 is fixed to the outer side of the door panel 220 .

[0068] Specifically, the heating assembly 221 includes a heating seat 2211 and a heating tube 2212 . The heating seat 2211 is fixed on the door panel 220 , and a group of evenly distributed heating tubes 2212 are fixed inside the heating seat 2211 .

[0069] The operation process of this embodiment is as follows: when it is necessary to heat the sample, the No. 1 touch screen 222 on the door panels 220 on both sides respectively activates the heating tubes 2212 in the heating components 221 on both sides, and the fish tissue sample is heated by the heating tubes 2212, and the heating can dry the fish tissue sample. Heating and drying the sample at a lower temperature such as 40-50°C can remove moisture from the sample. The dried sample is easier to store and transport, and the dried sample is also more convenient to operate when performing some analyses such as dry matter content determination, chemical analysis of certain components, etc., because the removal of moisture can reduce the interference of moisture on the analysis results;

[0070] In addition, before use, take out the entire protective cover 200, then pull out the placement rack 300, and then place each weighing cup 500 that needs to be used on a high-temperature resistant operating table, then cover the outside of each weighing cup 500 with the protective cover 200, and use a high-temperature resistant plate to cover the top of the protective cover 200, and use the No. 1 touch screen 222 on the door panels 220 on both sides to start each heating tube 2212 in the heating assembly 221 on both sides, and adjust the temperature to the highest. Through the action of the heating tube 2212, the internal space of the protective cover 200 is quickly placed in a high-temperature state, which can be used for disinfection and drying of the weighing cup 500.
