Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a liquid milk sampler. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to sampling devices is also constantly improving. Milk is an important beverage in daily life, and its quality is directly related to people's health. In the dairy industry, it is usually necessary to use sampling devices to sample and test liquid milk.

[0003] The current samplers are inconvenient for quickly stirring the milk before sampling liquid milk, and they cannot quickly seal the test tube containing the sample. Without stirring, sediment is likely to accumulate at the bottom of the milk in the storage container, resulting in uneven distribution of milk components. Direct sampling yields low-precision samples, which can reduce the accuracy of subsequent tests and is not conducive to sampling liquid milk. The samplers have poor sampling performance. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the samplers currently used are inconvenient to quickly stir the milk before sampling liquid milk, and cannot quickly seal the test tube containing the sample. Without stirring, sediment is likely to accumulate at the bottom of the milk in the storage container, the milk components are unevenly distributed, the sample obtained by direct sampling has low precision, and it is easy to reduce the accuracy of subsequent tests. Therefore, a liquid milk sampler is proposed.

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

[0006] A liquid milk sampler includes a support platform and a storage tank. A first reciprocating screw is rotatably connected to the support platform. A slider is threaded onto the first reciprocating screw. A bending rod is rotatably connected to the slider. A hydraulic cylinder is fixedly connected to the lower end of the bending rod. A fixing block is fixedly connected to the driving end of the hydraulic cylinder. A suction cylinder is fixedly connected to the bottom of the fixing block. A suction assembly is provided inside the suction cylinder. Multiple stirring rods are fixedly connected to one side of the suction cylinder.

[0007] A rotating box is rotatably connected to the support platform. Multiple test tubes arranged in a circular array are snapped into the rotating box. A sliding assembly is provided on the support platform. The sliding assembly includes a sealing plate that is slidably installed on the support platform. A circular hole is provided on the sealing plate.

[0008] Preferably, the suction assembly includes a piston slidably mounted inside the suction cylinder, and an electric push rod is fixedly disposed inside the fixing block, with the drive end of the electric push rod fixedly connected to the upper surface of the piston.

[0009] Preferably, a second reciprocating lead screw is rotatably connected to the support platform, and the sealing plate and the second reciprocating lead screw are threadedly connected.

[0010] Preferably, a rotating wheel is threaded onto the second reciprocating screw, and the rotating wheel is provided with anti-slip texture.

[0011] Preferably, the support platform is provided with a sliding groove, and the slider and the sliding groove are slidably connected.

[0012] Preferably, a first motor is mounted on the slider, and the drive end of the first motor is fixedly connected to the bending rod. A second motor and a third motor are mounted on the support platform, and the drive ends of the second motor and the third motor are fixedly connected to the first reciprocating lead screw and the rotating box, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During the rotation of the suction cylinder and multiple stirring rods, the milk to be tested inside the storage tank can be thoroughly stirred, preventing sediment from forming at the bottom of the storage tank. The electric push rod drives the piston downward, pushing the milk to be tested out of the suction cylinder. The milk to be tested passes through the round hole and falls into the test tube directly below the round hole. Then, the third motor drives the rotating box to rotate at a certain angle, and the test tube containing the sample milk will be offset from the round hole, with the upper end of the test tube in close contact with the rubber surface of the sealing plate. This can quickly seal the test tube containing the sample, preventing impurities from falling into the test tube, effectively improving the accuracy of the sample obtained, and thus improving the accuracy of subsequent testing. The sampler has a good sampling effect. 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] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-5 A liquid milk sampler includes a support platform 1 and a storage tank 11. A first reciprocating screw 5 is rotatably connected to the support platform 1. A slider 4 is threaded onto the first reciprocating screw 5. A bending rod 3 is rotatably connected to the slider 4. A hydraulic cylinder 2 is fixedly connected to the lower end of the bending rod 3. A fixing block 9 is fixedly connected to the driving end of the hydraulic cylinder 2. A suction cylinder 10 is fixedly connected to the bottom of the fixing block 9. A suction assembly is provided inside the suction cylinder 10. Multiple stirring rods 12 are fixedly connected to one side of the suction cylinder 10. A rotating box 8 is rotatably connected to the support platform 1. Multiple test tubes 15 arranged in a ring array are clamped inside the rotating box 8. A sliding assembly is provided on the support platform 1. The sliding assembly includes a sealing plate 7 slidably mounted on the support platform 1. A circular hole is opened on the sealing plate 7.

[0024] The suction assembly includes a piston 16 that is slidably installed inside the suction cylinder 10. An electric push rod is fixedly installed inside the fixing block 9. The drive end of the electric push rod is fixedly connected to the upper surface of the piston 16. The electric push rod drives the piston 16 to move upward. The piston 16 has good sealing when connected to the inner wall of the suction cylinder 10. When the piston 16 moves upward, part of the liquid milk to be tested in the storage tank 11 can be drawn into the suction cylinder 10.

[0025] A second reciprocating screw 13 is rotatably connected to the support platform 1. The sealing plate 7 is threadedly connected to the second reciprocating screw 13. A rotating wheel 14 is threadedly connected to the second reciprocating screw 13. The rotating wheel 14 is provided with anti-slip texture. When the rotating wheel 14 rotates, the second reciprocating screw 13 will rotate together. The sealing plate 7 will move upward along the second reciprocating screw 13 and slide vertically relative to the support platform 1. After the sealing plate 7 moves, there will be a large distance between it and the rotating box 8, which makes it convenient to take out the test tube 15 inside the rotating box 8.

[0026] The support platform 1 has a sliding groove 6, and the slider 4 is slidably connected to the sliding groove 6. The sliding groove 6 can limit the movement trajectory of the slider 4 and prevent the slider 4 from swinging. A first motor is installed on the slider 4, and the drive end of the first motor is fixedly connected to the bending rod 3. A second motor and a third motor are installed on the support platform 1. The drive ends of the second motor and the third motor are fixedly connected to the first reciprocating screw 5 and the rotating box 8, respectively. The second motor drives the first reciprocating screw 5 to rotate, and the slider 4 will move along the first reciprocating screw 5. The third motor drives the rotating box 8 to rotate at a certain angle, and the test tube 15 containing the sample milk will be offset from the round hole. The upper end of the test tube 15 is in close contact with the rubber surface of the sealing plate 7, which can quickly seal the test tube 15 containing the sample.

[0027] In this invention, in the initial state, the lower surface of the rubber material of the sealing plate 7 is simultaneously attached to the upper surface of multiple test tubes 15, and the sealing performance of the sealing plate 7 and the test tubes 15 is good. Then, the storage container 11 containing the liquid milk to be tested is placed on the support platform 1, and the hydraulic cylinder 2 drives the fixing block 9 to move down until the suction cylinder 10 and multiple stirring rods 12 are inserted into the liquid milk to be tested. Then, the first motor drives the bending rod 3 to rotate. During the rotation of the suction cylinder 10 and multiple stirring rods 12, the liquid milk to be tested inside the storage container 11 can be fully stirred to avoid sediment at the bottom of the storage container 11. Then, the electric push rod drives the piston 16 to move up. The sealing performance of the piston 16 when connected to the inner wall of the suction cylinder 10 is good. When the piston 16 moves up, part of the liquid milk to be tested in the storage container 11 can be drawn into the suction cylinder 10.

[0028] Then, hydraulic cylinder 2 drives fixed block 9 to move upward until suction cylinder 10 is moved above storage tank 11. Then, second motor drives first reciprocating screw 5 to rotate, and slider 4 moves along first reciprocating screw 5, thereby moving suction cylinder 10 above rotating box 8. At this time, suction cylinder 10 is directly above the round hole, and the distance between it and sealing plate 7 is very small. Then, electric push rod drives piston 16 to move downward, which pushes out the milk to be tested liquid inside suction cylinder 10. The milk to be tested liquid will pass through the round hole and fall into test tube 15 directly below the round hole. Then, third motor drives rotating box 8 to rotate a certain angle, and test tube 15 containing sample milk will be offset from the round hole, and the upper end of test tube 15 will be in close contact with the rubber surface of sealing plate 7. This can quickly seal test tube 15 containing sample, prevent impurities from falling into test tube 15, and effectively improve the accuracy of sample collection, so as to improve the accuracy of subsequent testing.
