Description

Technical Field

[0001] This utility model relates to the field of soil environmental monitoring, specifically a soil moisture testing and comparison device. Background Technology

[0002] Agricultural Internet of Things (IoT), which uses various instruments to display data in real time or participate in automatic control as parameters, can provide a scientific basis for precise greenhouse regulation, achieving the goals of increasing yield, improving quality, regulating growth cycles, and enhancing economic benefits. Soil moisture is measured using a soil moisture meter, which measures the dielectric constant of the soil to directly and stably reflect the true moisture content of various soil types. Soil moisture is a crucial factor affecting crop growth, the soil ecological environment, and water resource management. Accurate measurement of soil moisture is of great significance for agricultural irrigation, geological exploration, and environmental monitoring. Currently, various soil moisture detection instruments exist on the market, but most of these instruments can only measure soil moisture at a single location or depth, and cannot simultaneously compare and analyze soil moisture at different depths or locations. This, to some extent, limits the comprehensive understanding and research of soil moisture variation patterns. Utility Model Content

[0003] The purpose of this invention is to provide a soil moisture testing and comparison device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soil moisture testing and comparison device, comprising a mounting platform, a detection component, and an adjustment component;

[0005] Among them: multiple hinge supports are installed around the bottom of the mounting platform, and support legs are hinged to the surface of the hinge supports;

[0006] The detection assembly includes a mounting sleeve fixedly installed in the middle of the mounting platform. A hollow column is slidably provided inside the mounting sleeve. A mounting ring is installed at the bottom of the hollow column. Humidity detection probes are installed on both sides of the mounting ring. A transmission line is connected to the top of the humidity detection probes. A mounting box is installed on the top of the mounting platform. A sealed box is installed on the top of the mounting box. A reading display is installed inside the sealed box.

[0007] The adjustment assembly includes a lead screw rotatably mounted inside a mounting sleeve, the lead screw passing through a hollow column, a slider fixedly mounted on the top of the hollow column, strip-shaped limiting grooves extending through both sides of the surface of the mounting sleeve, limiting blocks fixedly mounted on both sides of the slider, the limiting blocks slidingly passing through the strip-shaped limiting grooves, and a rocker arm rotatably mounted on the surface of the mounting box, the rocker arm being drivenly connected to the top end of the lead screw.

[0008] As a preferred embodiment of this utility model: a transmission rod is fixedly installed on the surface of the rocker arm, one end of the transmission rod extends into the interior of the mounting box and is fixedly installed with a worm gear, and a worm wheel is fixedly installed at the top of the lead screw, and the worm wheel is meshed with the worm gear.

[0009] As a preferred embodiment of this utility model: the surface of the mounting sleeve is engraved with scale lines on one side of the strip-shaped limiting groove, and the limiting block corresponds to the scale lines.

[0010] As a preferred embodiment of this utility model, the transmission rod is threaded with a locking nut.

[0011] As a preferred embodiment of this utility model: each of the support legs is fixedly equipped with a connecting buckle, and one of the connecting buckles is equipped with a Velcro strap on its surface.

[0012] As a preferred embodiment of this utility model: a wire buckle is installed on the surface of the hollow column, and the transmission line is engaged inside the wire buckle.

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

[0014] (1) A lead screw is rotatably installed inside the mounting sleeve. When the rocker arm drives the worm gear to rotate through the transmission rod, the worm gear drives the worm wheel at the top of the lead screw to rotate, so that the lead screw rotates inside the mounting sleeve. The rotation of the lead screw drives the slider on the surface to rotate. Since the slider is equipped with limit blocks on both sides and the limit blocks slide through the strip-shaped limit groove opened on the surface of the mounting sleeve, the slider on the surface slides up and down along the strip-shaped limit groove when the lead screw rotates. The sliding up and down of the slider drives the humidity detection probe installed at the bottom of the hollow column to insert into the soil, thereby adjusting the depth of the humidity detection probe inserted into the soil. It can detect soil at different depths and compare and analyze the soil humidity through the multiple sets of data obtained.

[0015] (2) A hollow column is slidably installed inside the mounting sleeve through the provided detection components. A mounting ring is installed at the bottom of the hollow column. Humidity detection probes are installed on both sides of the mounting ring. The hollow column drives the humidity detection probes to insert into the soil at the detection depth to detect the soil moisture. The detection data is transmitted to the reading display through the transmission line for the sampling personnel to observe and record. A sealed box is installed on the top of the mounting box. The reading display is installed inside the sealed box to protect it and prevent damage caused by bumps during transport. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1 - Figure 4 A soil moisture testing and comparison device includes: a mounting platform 1, a detection component 4, and an adjustment component 5; a plurality of hinge supports 2 are mounted around the bottom end of the mounting platform 1, and support legs 3 are hingedly mounted on the surface of the hinge supports 2.

[0026] Please see Figure 1 , Figure 3 The detection component 4 includes a mounting sleeve 41 fixedly installed in the middle of the mounting platform 1. A hollow column 42 is slidably provided inside the mounting sleeve 41. A mounting ring 43 is installed at the bottom of the hollow column 42. Humidity detection probes 44 are installed on both sides of the mounting ring 43. A transmission line 45 is connected to the top of the humidity detection probes 44. A mounting box 46 is installed on the top of the mounting platform 1. A sealing box 47 is installed on the top of the mounting box 46. A reading display 48 is installed inside the sealing box 47.

[0027] In practical use: A hollow column 42 is slidably installed inside the mounting sleeve 41. A mounting ring 43 is installed at the bottom of the hollow column 42. Humidity detection probes 44 are installed on both sides of the mounting ring 43. The hollow column 42 drives the humidity detection probes 44 to insert into the soil at the detection depth to detect the soil moisture. The detected data is transmitted to the reading display 48 through the transmission line 45 for the sampling personnel to observe and record. A sealed box 47 is installed on the top of the mounting box 46. The reading display 48 is installed inside the sealed box 47 for protection to prevent damage caused by bumps during transportation.

[0028] Please see Figure 1 , Figure 4 The adjusting assembly 5 includes a lead screw 51 rotatably installed inside the mounting sleeve 41, the lead screw 51 passing through the hollow column 42, a slider 52 fixedly installed on the top of the hollow column 42, a strip-shaped limiting groove 53 extending through both sides of the surface of the mounting sleeve 41, a limiting block 54 fixedly installed on both sides of the slider 52, the limiting block 54 slidingly passing through the strip-shaped limiting groove 53, a rocker arm 55 rotatably installed on the surface of the mounting box 46, the rocker arm 55 being drivenly connected to the top end of the lead screw 51, a transmission rod 56 fixedly installed on the surface of the rocker arm 55, one end of the transmission rod 56 extending into the interior of the mounting box 46 and fixedly installed with a worm gear 57, a worm wheel 58 fixedly installed on the top end of the lead screw 51, the worm wheel 58 meshing with the worm gear 57.

[0029] In practical use: A lead screw 51 is rotatably installed inside the mounting sleeve 41. When the rocker arm 55 drives the worm gear 57 to rotate via the transmission rod 56, the worm gear 57 drives the worm wheel 58 at the top of the lead screw 51 to rotate as well, thus causing the lead screw 51 to rotate inside the mounting sleeve 41. The rotation of the lead screw 51 drives the slider 52 on the surface to rotate as well. Since limit blocks 54 are installed on both sides of the slider 52 and the limit blocks 54 slide through the strip-shaped limit groove 53 opened on the surface of the mounting sleeve 41, the slider 52 on the surface slides and rises and falls along the strip-shaped limit groove 53 when the lead screw 51 rotates. The sliding and rising and falling of the slider 52 drives the humidity detection probe 44 installed at the bottom of the hollow column 42 to be inserted into the soil, thereby adjusting the insertion depth of the humidity detection probe 44 into the soil. This allows for detection of soil at different depths, and the soil moisture can be compared and analyzed by obtaining multiple sets of data.

[0030] Please see Figure 1 , Figure 4 The surface of the mounting sleeve 41 is engraved with a scale line 6 on one side of the strip-shaped limiting groove 53, and the limiting block 54 corresponds to the scale line 6.

[0031] In practical use: The scale line 6 engraved on the surface of the mounting sleeve 41 on one side of the strip-shaped limiting groove 53 is used to observe the descent depth of the limiting block 54. When the humidity detection probe 44 contacts the soil, observe the position of the limiting block 54 corresponding to the scale line 6. When the slider 52 continues to move down, it drives the humidity detection probe 44 to insert into the soil. After stopping the downward movement, observe the value corresponding to the limiting block 54 and the scale line 6 to obtain the depth of the soil detected by the humidity detection probe 44.

[0032] Please see Figure 2 , Figure 4 The transmission rod 56 has a locking nut 7 connected to its surface by threads.

[0033] In practical use: The surface of the transmission rod 56 is threaded with a locking nut 7. By tightening the locking nut 7, the transmission rod 56 is fixed, thereby preventing accidental activation of the rocker arm 55.

[0034] Please see Figure 2 Each of the support legs 3 has a connecting buckle 8 fixedly installed on its surface. One of the connecting buckles 8 has a Velcro strap 9 installed on its surface. One end of the Velcro strap 9 passes through the inside of the connecting buckle 8 and is then attached to itself.

[0035] In practical use: The surface of the support leg 3 is equipped with a connecting buckle 8, and one of the connecting buckles 8 is connected to a Velcro strap 9. When the device is not in use, the support leg 3 is retracted, and the Velcro strap 9 passes through the inside of the connecting buckle 8. Finally, one end of the Velcro strap 9 is glued to the surface, which serves to fix and tighten the support leg 3.

[0036] Please see Figure 1 , Figure 4 A wire clip 10 is installed on the surface of the hollow column 42, and the transmission line 45 is engaged inside the wire clip 10.

[0037] In practical use: the wire clips 10 connected to the surface of the hollow column 42 are used to fix the transmission line 45 and prevent the transmission line 45 from sliding against the inner wall of the mounting sleeve 41 and causing wear.

[0038] A lead screw 51 is rotatably installed inside the mounting sleeve 41. When the rocker arm 55 drives the worm gear 57 to rotate via the transmission rod 56, the worm gear 57 drives the worm wheel 58 at the top of the lead screw 51 to rotate as well, thus causing the lead screw 51 to rotate inside the mounting sleeve 41. The rotation of the lead screw 51 drives the slider 52 on the surface to rotate as well. Since limit blocks 54 are installed on both sides of the slider 52 and the limit blocks 54 slide through the strip-shaped limit groove 53 opened on the surface of the mounting sleeve 41, the slider 52 on the surface slides and rises and falls along the strip-shaped limit groove 53 when the lead screw 51 rotates. The sliding and rising and falling of the slider 52 drives the humidity detection probe 44 installed at the bottom of the hollow column 42 to insert into the soil, thereby adjusting the insertion depth of the humidity detection probe 44 into the soil. This allows for detection of soil at different depths, and the soil moisture can be compared and analyzed by obtaining multiple sets of data.
