Description

Technical Field

[0001] This utility model belongs to the field of soil testing technology, and more specifically, it relates to a rapid soil moisture detection sampler that prevents clogging. Background Technology

[0002] Soil refers to a loose layer of material on the Earth's surface, composed of minerals formed from the weathering of rocks, organic matter produced from the decomposition of plant and animal remains and microbial remains, soil organisms (solid phase), water (liquid phase), air (gaseous phase), humus, etc.

[0003] Soil is an essential condition for plant growth. Plants need a good soil environment to grow. Different plants or even the same plant at different growth stages have different requirements for the soil environment. By using a soil moisture sampler to detect changes in the moisture content of the soil, users can understand changes in the basic soil conditions in a timely manner, determine whether the plants are short of water, and thus ensure that the plants grow in a relatively ideal soil environment.

[0004] Common soil moisture sampling devices utilize a sampling tube, where external force is applied downwards to force a hollow tube into the soil, squeezing soil from different depths into the sampling tube for extraction. After soil sampling and testing, the soil in the sampling tube needs to be drained for subsequent sampling operations. However, if the soil at the sampling point is too viscous, some soil may become stuck inside the sampler, making subsequent sampling difficult, leading to significant errors in the sample and ultimately affecting the accuracy of the test results.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a rapid soil moisture detection sampler that is clogging-resistant, in order to achieve a more practical purpose. Utility Model Content

[0006] In view of the problems mentioned in the background art above, the present invention provides a rapid soil moisture detection sampler that prevents clogging, which can avoid the clogging of the sampling tube by wet soil during soil sampling.

[0007] The technical solution adopted by this utility model is as follows: a rapid soil moisture detection sampler for preventing clogging includes a sampling tube for collecting soil, a connecting seat fixedly installed on the sampling tube, a movable rod slidably disposed inside the sampling tube through the connecting seat, and a working plate fixedly installed at the bottom of the movable rod for loosening the soil. The diameter of the working plate is equal to the inner diameter of the sampling tube. A vent hole is opened through the working plate. A vent groove is opened on the connecting seat to connect the inside of the sampling tube with the outside. A cavity is opened in the working plate, and a movable component for blocking the vent hole is provided in the cavity.

[0008] The technical principle of this utility model is as follows: When taking soil samples, the sampling tube is gradually pressed into the soil, and the soil will be gradually squeezed into the sampling tube. At this time, the vent is opened, and the air in the sampling tube is discharged through the vent and the vent groove.

[0009] After the soil in the sampling tube is tested, the vent is covered by the movable component. The working plate is moved downward by the movable rod to loosen the soil blocking the sampling tube, so that the soil in the sampling tube can be discharged to ensure the smooth progress of subsequent sampling. The air between the working plate and the soil is discharged through the vent.

[0010] Furthermore, the movable rod has a central through hole that is coaxial with the movable rod and communicates with the interior of the cavity. The movable component includes a baffle disposed in the cavity and a rotating rod disposed in the central through hole for driving the baffle to rotate.

[0011] Furthermore, an installation cylinder with a spiral groove on its outer wall is fixedly installed on the connecting seat, and an internal thread that connects with the spiral groove is provided on the inner wall of the sampling cylinder.

[0012] Furthermore, a drill bit for breaking the soil is provided at the end of the sampling tube away from the connecting seat.

[0013] Furthermore, a limiting cylinder for limiting the movable rod is provided on the side of the connecting seat away from the sampling cylinder. A limiting groove is opened on the side wall of the limiting cylinder, and a handle that slides in the limiting groove is fixedly installed on the side wall of the movable rod.

[0014] Furthermore, a limiting groove for limiting the handle is provided at the end of the limiting cylinder away from the connecting seat.

[0015] The beneficial effects of this utility model are:

[0016] 1. The design of the sampling tube, movable rod, and working plate can loosen the soil blocking the sampling tube, ensuring the smooth progress of subsequent sampling.

[0017] 2. The baffle and rotating rod allow for the opening and closing of the ventilation holes, preventing soil from entering the upper part of the working board through the ventilation holes.

[0018] 3. With the setting of the limiting cylinder, when pressing the sampling cylinder, the handle is applied in the limiting groove, and the sampling cylinder is pressed into the soil through the limiting cylinder, which saves time and effort. Attached Figure Description

[0033] like Figures 1-3 As shown, a rapid soil moisture detection sampler for preventing clogging includes a sampling cylinder 1 for collecting soil, a connecting seat 2 fixedly installed on the sampling cylinder 1, a movable rod 3 slidably disposed inside the sampling cylinder 1 through the connecting seat 2, and a working plate 4 fixedly installed on the movable rod 3 for loosening the soil. The diameter of the working plate 4 is equal to the inner diameter of the sampling cylinder 1. A vent hole 401 is opened on the working plate 4, and a vent groove 201 is opened on the connecting seat 2 to connect the inside of the sampling cylinder 1 with the outside. A cavity 402 is opened inside the working plate 4, and a movable component for blocking the vent hole 401 is provided in the cavity.

[0034] The length of the movable rod 3 is greater than the height of the sampling cylinder 1. The sampling cylinder 1 and the working plate 4 are made of 304 stainless steel. 304 stainless steel has a high chromium content, a smooth surface, and strong corrosion resistance, making it suitable for scenarios involving long-term contact with soil and effectively preventing rust or chemical contamination. The movable rod 3 is a hollow rod, with a thickness ranging from 1mm to 2mm. To ensure sufficient strength and reduce the weight of the movable rod 3, a thickness of 1.5mm is preferred.

[0035] The working plate 4 is welded to the movable rod 3, or the working plate 4 and the movable rod 3 can be integrally formed. The movable rod 3 slides through the connecting seat 2. During soil sampling, the sampling tube 1 is gradually pressed into the soil. The soil is gradually squeezed into the sampling tube 1. At this time, the vent 401 opens, and the air in the sampling tube 1 is discharged through the vent 401 and the vent groove 201 until the sampling is completed. To prevent soil from entering the upper part of the working plate 4 through the vent 401, the diameter of the vent 401 is less than 1 cm. When it is necessary to remove the sampling tube 1 from the soil, lift the movable rod upward. Under the action of the movable rod 3 and the working plate 4, the sampling tube 1 can be removed from the soil. The operation is simple.

[0036] After sampling, the probe of the soil moisture detection device can be inserted into the sampling tube 1 to detect the soil moisture in the sampling tube 1. The setting of the sampling tube 1 can reduce the loss of soil moisture and improve the accuracy of the detection data.

[0037] After the soil testing in sampling cylinder 1 is completed, the vent 401 is covered by the movable component. The movable rod 3 moves the working plate 4 downward, loosening the soil blocking the sampling cylinder 1 and allowing it to be discharged, ensuring smooth subsequent sampling. The diameter of the working plate 4 is equal to the inner diameter of the sampling cylinder 1. When discharging soil, the working plate 4 can scrape off the soil on the inner wall of the sampling cylinder 1, further improving the anti-clogging effect of the device. It can also reduce the mixing of different soil samples and improve the accuracy of the test results.

[0038] Furthermore, the movable rod 3 has a central through hole 301 that is coaxially arranged with the movable rod 3 and communicates with the interior of the cavity 402. The movable component includes a baffle 9 disposed in the cavity 402 and a rotating rod 10 disposed in the central through hole 301 for driving the baffle 9 to rotate.

[0039] The baffle 9 consists of a central circular plate 901 coaxially arranged with the rotating rod 10 and several shielding plates 902 with an area larger than the vent holes 401. The central circular plate 901 and the shielding plates 902 are connected by a connecting plate 903. The central circular plate 901 is horizontally rotatably arranged in the cavity 402. The number of shielding plates 902 is equal to the number of vent holes 401, which is 6 in this case.

[0040] The horizontal rotation of the rotating rod 10 drives the central circular plate 901 to rotate synchronously, thereby moving the shield 902 and opening and closing the vent 401. When soil sampling is required, the vent 401 is opened to ensure smooth airflow and facilitate subsequent sampling. When soil needs to be discharged, the rotation of the rotating rod 10 causes the shield 902 to align with the vent 401, making the bottom of the working plate 4 nearly flat and preventing soil from entering the upper part of the working plate 4 through the vent 401.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, a mounting cylinder 5 with a spiral groove on its outer wall is fixedly installed on the connecting seat 2, and an internal thread that connects with the spiral groove is provided on the inner wall of the sampling cylinder 1.

[0042] When soil samples need to be transported, the above-mentioned design allows for easy detachment of the sampling tube 1 from the connecting seat 2, thereby reducing the overall size of the device and making it easier to carry.

[0043] The diameter of the ventilation hole 401 is no more than 1 cm, which ensures ventilation while reducing soil entry. The extension rod 201 can remove soil that enters the ventilation hole 401, ensuring the normal use of the device.

[0044] Furthermore, such as Figure 3 As shown, a drill bit 6 for breaking the soil is provided at the end of the sampling tube 1 away from the connecting seat 2.

[0045] By setting the drill bit 6, soil resistance can be reduced, sampling speed can be increased, and it is easier for the sampling tube 1 to enter the soil.

[0046] Furthermore, such as Figure 3 As shown, a limiting cylinder 7 for limiting the movable rod 3 is provided on the side of the connecting seat 2 away from the sampling cylinder 1. A limiting groove 701 is opened on the side wall of the limiting cylinder 7, and a handle 8 that slides in the limiting groove 701 is fixedly installed on the side wall of the movable rod 3.

[0047] When it is necessary to press the sampling tube 1 into the soil, lift the movable rod 3 upward until the handle 8 leaves the limiting groove 701, rotate the movable rod 3 horizontally so that the handle 8 abuts against the upper end face of the limiting tube 7. Under the action of the handle 8 and the limiting tube 7, the sampling tube 1 is pressed into the soil. The operation is time-saving and labor-saving, and improves sampling efficiency.

[0048] When it is necessary to remove the sampling tube 1 from the soil, lift the handle 8 upwards, and the sampling tube 1 can be removed from the soil under the action of the movable rod 3 and the working plate 4.

[0049] Furthermore, such as Figure 3 As shown, the end of the limiting cylinder 7 away from the connecting seat 2 has a limiting groove 702 for limiting the handle 8.

[0050] By setting the limiting groove 702, it is possible to prevent the handle 8 from sliding between the limiting cylinder 7 when the sampling cylinder 1 is pressed down, thereby ensuring the safe use of this device.

It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
