Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil sample storage and transfer device. Background Technology

[0002] Soil sampling is a fundamental task in fields such as earth science, agriculture, and environmental monitoring. By analyzing samples, we can understand the physical and chemical properties of the soil, pollution status, etc., and provide data support for agricultural production and environmental governance. However, samples need to be transported from collection to laboratory analysis. If they come into direct contact with the outside world, they are easily affected by changes in temperature and humidity, pollution, etc., which can lead to water evaporation and changes in composition, affecting the accuracy of the test. Therefore, transfer boxes are needed to isolate the samples. To maintain the original state of the samples, low-temperature preservation is required. Considering the cost, ice packs are often placed in the boxes to create a low-temperature environment.

[0003] However, the following problems were found during use: uneven temperature occurred between the upper and lower layers inside the box, with the lower layer near the ice pack being colder and the upper layer being hotter, resulting in inconsistent temperature distribution of sample storage bottles in different locations and affecting the sample preservation effect.

[0028] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 - Figure 6 A soil sample storage and transfer device includes a box 1 and a sample storage bottle 21. It should be noted that the box 1 is a box 1 with a lid structure, which can be closed after the soil sample is put in to maintain a seal. The main body of the box 1 and the lid are locked together by a lock. The sample storage bottle 21 is used to put in the soil sample. A drawer 22 is provided on the box 1 near the bottom. The drawer 22 is also provided with a latch to the box 1, which can lock the drawer 22 to the box 1 during transportation. It is used to put ice packs. A baffle mechanism is provided on the top of the drawer 22.

[0030] The turbulence-disrupting mechanism includes a rotating shaft 2 rotatably connected to the side wall of the housing 1, and a plurality of turbulence-disrupting plates 3 are provided on the rotating shaft 2, located directly above the drawer 22;

[0031] Furthermore, the end of the rotating shaft 2 is also provided with a power unit for driving the rotating shaft 2 to rotate.

[0032] Specifically, ice packs are placed inside drawer 22, and drawer 22 is placed inside box 1. Then, the power unit drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the baffle 3 to rotate above the ice pack. Thus, when the temperature of the upper and lower layers inside box 1 is uneven, the rotation of the baffle 3 can be used to equalize the air temperature inside box 1 from time to time, thereby ensuring that the soil samples inside sample storage bottle 21 are kept at the same preservation temperature.

[0033] Furthermore, the power unit includes a mounting bracket 4 disposed on the inner side wall of the housing 1, and a drive gear 6 is rotatably connected to the mounting bracket 4;

[0034] Furthermore, a spring 5 is provided inside the mounting frame 4, with one end of the spring 5 mounted on the mounting frame 4 and the other end of the spring 5 connected to a connecting block 7 mounted on the drive gear 6.

[0035] The end of the drive gear 6 is provided with a knob 8, which is used to drive the drive gear 6 to rotate in the opposite direction, thereby storing power through the spring 5;

[0036] The rotating shaft 2 is provided with a driven gear 9, which meshes with the driving gear 6. It should be noted that the radius of the driving gear 6 is larger than that of the driven gear 9, which can increase the rotational speed and the number of rotations of the rotating shaft 2 within the elastic potential energy of the spring 5.

[0037] Specifically, raising the rotary knob 8 causes the drive gear 6 to rotate, which in turn causes the spring 5 to store power. Then, releasing the knob 8 causes the drive gear 6 to rotate under the action of the spring 5. The drive gear 6 then drives the driven gear 9 to rotate, thereby achieving the rotation of the spoiler 3.

[0038] Furthermore, the inner wall of the housing 1 is provided with several mounting slots 10. A first connecting frame 11 and a second connecting frame 12 are inserted into the inside of the mounting slots 10. Several central support frames 15 are fixedly connected together on the first connecting frame 11. Each central support frame 15 is provided with a sliding shaft 16. Each sliding shaft 16 is slidably connected with a front support frame 18. A front baffle 19 is provided on the side wall of the front support frame 18 away from the central support frame 15.

[0039] Furthermore, the second connecting frame 12 is provided with several rear support frames 13 that are fixedly connected together side by side. The side wall of the rear support frame 13 away from the middle support frame 15 is provided with a rear baffle 14 that works in conjunction with the front baffle 19. The number and size of the rear support frame 13, the middle support frame 15 and the front support frame 18 are the same. It should be noted that the rear support frame 13, the middle support frame 15 and the front support frame 18 are preferably made of plastic, which has low manufacturing cost and is easier to replace.

[0040] Furthermore, each of the sliding shafts 16 is provided with a limiting strip 17, and the limiting strip 17 is arranged through the corresponding front support frame 18, which can prevent the front support frame 18 from rotating on the sliding shaft 16.

[0041] Furthermore, a spring 20 is sleeved on the outer side of the sliding shaft 16, and one end of the spring 20 is connected to the front support frame 18 and the other end is connected to the middle support frame 15. Through the tension of the spring 20, the sample storage bottle 21 placed on the rear support frame 13, the middle support frame 15 and the front support frame 18 is restricted between the rear baffle 14 and the front baffle 19.

[0042] Specifically, firstly, the first connecting frame 11 and the second connecting frame 12 are inserted parallel to each other into the corresponding mounting slots 10. Then, the sample storage bottle 21 containing the soil sample is placed on the rear support frame 13 and the middle support frame 15. Before this, the front support frame 18 can be pulled by hand to move it away from the middle support frame 15. Then, the front support frame 18 is released and the sample storage bottle 21 is restricted between the rear baffle 14 and the front baffle 19 under the action of the spring 20. The fixing structure of the front support frame 18, the middle support frame 15 and the rear support frame 13 in conjunction with the spring 20 replaces the traditional sponge fixing method, which greatly reduces the contact area with the sample storage bottle 21, reduces heat accumulation, reduces the risk of moisture loss due to excessive temperature, and better preserves the original characteristics of the sample.

[0043] Furthermore, the bottom surface of the drawer 22 is a sloping structure, and a guide groove 25 is provided on the bottom surface of the drawer 22, located at the bottom of the slope. Because the ice in the ice pack will melt within a certain period of time, condensation will also be generated on the outer wall of the ice pack. Therefore, by setting the sloping structure, the water that melts on the ice pack can be collected along the slope towards the bottom of the slope, and then flow out from the inside of the drawer 22 through the guide groove 25. Moreover, under the action of the turbulence mechanism, the cold air can be better wrapped around the sample storage bottle 21, improving the preservation effect.

[0044] Furthermore, the drawer 22 is provided with a water outlet that is connected to the guide groove 25, and a rubber stopper 24 is provided inside the water outlet. The function of the rubber stopper 24 is to first control the melted water inside the drawer 22, and then pull the rubber stopper 24 out of the water outlet at an appropriate position to allow the melted water to drain out of the drawer 22.

[0045] Furthermore, the bottom of the drawer 22 is provided with a slide groove 23, and the inner bottom surface of the box body 1 is provided with a slide rail that matches the slide groove 23, which can limit the direction of the drawer 22 sliding and prevent the drawer 22 from getting stuck due to tilting during insertion into the box body 1.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
