Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil testing technology, and more specifically, to a sampling device for soil pH testing. Background Technology
[0002] Soil sampling devices are designed to detect the pH of soil at a fixed location by inserting the device into the soil and extracting the soil sample from the bottom. However, most existing soil sampling devices simply insert the device directly into the soil during sampling. If the sampling device is misaligned, it can easily result in the sampled soil layer not being the one that needs to be sampled, leading to overall data errors. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a sampling device for soil pH detection, which has the advantage of accurate soil sampling.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil pH testing, comprising a sleeve, a groove being provided inside the sleeve, a slider being slidably connected inside the groove, a fixing ring being fixedly installed on the outer side of the slider, a fixing block being fixedly installed on the outer side of the fixing ring, a connecting shaft being rotatably connected inside the fixing block, and a support rod being fixedly installed on the outer side of the connecting shaft.
[0005] As a preferred technical solution of this utility model, the fixed block has a second sliding groove inside, a second slider is slidably connected inside the second sliding groove, a first fixing plate is fixedly installed above the second slider, a level is fixedly installed on the inner side of the first fixing plate, and a second fixing plate is fixedly installed on the outer side of the first fixing plate.
[0006] As a preferred technical solution of this utility model, a sliding groove three is provided on the outer side of the sleeve, a sliding rod is slidably connected inside the sliding groove three, a support plate is fixedly installed above the sliding rod, a motor is fixedly installed above the support plate, a rotating shaft is fixedly installed at the output end of the motor, a spiral blade is fixedly installed on the outer side of the rotating shaft, and a soil-breaking cone is fixedly installed at the bottom of the rotating shaft.
[0007] As a preferred embodiment of this utility model, a scale is provided on the outer side of the sleeve, and two baffles are fixedly installed on the outer side of the sleeve, which are located on the left and right sides of the scale, respectively.
[0008] As a preferred embodiment of this utility model, the fixing ring is annular, there are multiple fixing blocks, and the multiple fixing blocks are respectively located on the outside of the fixing ring. There are four connecting shafts and four support rods, and the four connecting shafts and four support rods are all located on the outside of the sleeve. The bottom of the four support rods is conical.
[0009] As a preferred embodiment of this utility model, there are four sliding grooves and four sliding rods, and all four sliding grooves and four sliding rods are located on the outside of the support rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model has a level fixedly installed on the inner side of a fixed plate one and on the outer side of a fixed plate one. A fixed plate two is engaged inside the level. When the support rod is inserted into the surface of the soil to fix the sleeve by adjusting the angle through the rotation of the fixed block and the connecting shaft, the fixed plate one is installed above the fixed block through the sliding action of the slider two and the sliding groove two. The fixed plate one and the level are fixedly connected. After the support rod is inserted and the sleeve is fixed, the level can be used to check whether the device is perpendicular to the ground. This prevents the angle from shifting during soil extraction, which could cause errors in the extracted soil.
[0012] 2. This utility model features a motor fixedly installed above a support plate, a rotating shaft fixedly installed at the motor's output end, a spiral blade fixedly installed on the outside of the rotating shaft, and a soil-breaking cone fixedly installed at the bottom of the rotating shaft. When the motor is started, the rotating shaft rotates. Since the soil-breaking cone is fixedly connected to the rotating shaft, it contacts the ground, breaking up the soil and causing it to drill deeper into the ground. Simultaneously, the spiral blade transports the broken soil upwards. As the soil-breaking cone and spiral blade penetrate deeper, the support plate moves downwards through a sliding connection between a sliding rod and a sliding groove, allowing the soil-breaking cone to contact the soil to be tested. The spiral blade then removes the soil, achieving the sampling effect. Simultaneously, when soil is carried outwards, the soil at the bottom of the support plate is promptly cleared to prevent blockage. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5 As shown, this utility model provides a sampling device for soil pH testing, including a sleeve 1. A groove 2 is provided inside the sleeve 1. A slider 3 is slidably connected inside the groove 2. A fixing ring 4 is fixedly installed on the outside of the slider 3. A fixing block 5 is fixedly installed on the outside of the fixing ring 4. A connecting shaft 6 is rotatably connected inside the fixing block 5. A support rod 7 is fixedly installed on the outside of the connecting shaft 6.
[0021] When soil testing is required, the fixing ring 4 is first installed by sliding the slider 3 and the groove 2. Since the fixing ring 4 and the fixing block 5 are fixedly connected, and the connecting shaft 6 is located inside the fixing block 5 and is rotatably connected to the fixing block 5, the angle of the support rod 7 is adjusted by the rotatable connection between the fixing block 5 and the connecting shaft 6. Then the support rod 7 is inserted into the surface of the soil, thereby stabilizing the sleeve 1 and maintaining the overall stability.
[0022] The fixed block 5 has a groove 2 8 inside, and a slider 2 9 is slidably connected inside the groove 2 8. A fixed plate 10 is fixedly installed above the slider 2 9. A level 11 is fixedly installed on the inner side of the fixed plate 10, and a fixed plate 2 12 is fixedly installed on the outer side of the fixed plate 10.
[0023] After the support rod 7 is inserted into the surface of the soil and fixed by the rotation of the fixing block 5 and the connecting shaft 6, the sleeve 1 is fixed by the sliding action of the fixing plate 10 above the fixing block 5 through the sliding action of the slider 2 9 and the sliding groove 2 8. The fixing plate 10 is fixedly connected to the level 11. After the support rod 7 is inserted and the sleeve 1 is fixed, the level 11 can be used to check whether the device is perpendicular to the ground. This prevents the angle from shifting during soil extraction, which could cause errors in the extracted soil.
[0024] Among them, the outer side of the sleeve 1 is provided with a sliding groove 13, the sliding groove 13 is slidably connected with a sliding rod 14, a support plate 15 is fixedly installed above the sliding rod 14, a motor 16 is fixedly installed above the support plate 15, a rotating shaft 17 is fixedly installed at the output end of the motor 16, a spiral blade 18 is fixedly installed on the outer side of the rotating shaft 17, and a soil-breaking cone 19 is fixedly installed at the bottom of the rotating shaft 17.
[0025] The starter motor 16 drives the rotating shaft 17 to rotate. Since the soil-breaking cone 19 is fixedly connected to the rotating shaft 17, the soil-breaking cone 19 contacts the ground and breaks up the soil, causing the soil-breaking cone 19 to drill into the ground. At the same time, the spiral blade 18 will transport the broken soil upward. As the soil-breaking cone 19 and the spiral blade 18 go deeper downward, the support plate 15 will move downward through the sliding connection between the slide rod 14 and the slide groove 13, so that the soil-breaking cone 19 contacts the soil to be tested, and then the spiral blade 18 will take out the soil to achieve the sampling effect. At the same time, when the soil is carried out, the soil at the bottom of the support plate 15 should be cleaned in time to prevent blockage.
[0026] The sleeve 1 has a scale 20 on its outer side and a baffle 21 fixedly installed on its outer side. There are two baffles 21, which are located on the left and right sides of the scale 20, respectively.
[0027] The baffle 21 is a rectangular plate, and its main function is to block the outside of the scale 20. When sampling the soil, the support plate 15 will move downward through the outside of the sliding rod 14 and the sliding groove 13. At this time, the distance that the sliding rod 14 moves downward will be observed through the scale 20, so as to facilitate the observation of the required sampling depth and improve the sampling accuracy.
[0028] Among them, the fixing ring 4 is annular, there are multiple fixing blocks 5, and the multiple fixing blocks 5 are located on the outside of the fixing ring 4. There are four connecting shafts 6 and four support rods 7, and the four connecting shafts 6 and four support rods 7 are located on the outside of the sleeve 1. The bottom of the four support rods 7 is conical.
[0029] The main function of the four support rods 7 is to evenly fix the outer side of the sleeve 1 to the ground, so that the sleeve 1 remains perpendicular to the ground and maintains overall stability.
[0030] There are four slide grooves 13 and four slide rods 14, and all four slide grooves 13 and four slide rods 14 are located on the outside of the support rod 7.
[0031] The four slide rods 14 are slidably connected to the four slide grooves 13 respectively, so that when the motor 16 drives the rotating shaft 17 to rotate and move downward, it can support the plate 15 to move downward stably, giving it a certain degree of stability.
[0032] Working principle and usage process of this utility model:
[0033] First, the fixing ring 4 is installed by sliding the slider 3 and the groove 2. At this time, since the fixing ring 4 and the fixing block 5 are fixedly connected, and the connecting shaft 6 is located inside the fixing block 5 and is rotatably connected to the fixing block 5, the angle of the support rod 7 is adjusted by the rotatable connection between the fixing block 5 and the connecting shaft 6. Then, the support rod 7 is inserted into the surface of the soil, thereby stabilizing the sleeve 1 and maintaining the overall stability.
[0034] Secondly, a motor 16 is fixedly installed above the support plate 15, and a rotating shaft 17 is fixedly installed at the output end of the motor 16. A spiral blade 18 is fixedly installed on the outside of the rotating shaft 17, and a soil-breaking cone 19 is fixedly installed at the bottom of the rotating shaft 17. When the motor 16 is started, the rotating shaft 17 is driven to rotate. At this time, since the soil-breaking cone 19 and the rotating shaft 17 are fixedly connected, the soil-breaking cone 19 contacts the ground and breaks the soil, causing the soil-breaking cone 19 to drill into the ground. At the same time, the spiral blade 18 will transport the broken soil upward. As the soil-breaking cone 19 and the spiral blade 18 go deeper downward, the support plate 15 will move downward through the sliding connection between the slide rod 14 and the slide groove 13, so that the soil-breaking cone 19 contacts the soil to be tested, and then the spiral blade 18 removes the soil, achieving the sampling effect.
[0035] Secondly, a level 11 is fixedly installed on the inner side of the fixed plate 10 and on the outer side of the fixed plate 10. A second fixed plate 12 is engaged inside the level 11. After the support rod 7 is inserted into the surface of the soil to fix the sleeve 1 by adjusting the angle through the rotation of the fixed block 5 and the connecting shaft 6, the fixed plate 10 is installed above the fixed block 5 through the sliding action of the second slider 9 and the second groove 8. The fixed plate 10 and the level 11 are fixedly connected. After the support rod 7 is inserted and the sleeve 1 is fixed, the level 11 can be used to check whether the device is perpendicular to the ground.
[0036] Finally, when the soil is carried outward, clean the soil at the bottom of the support plate 15 in time to prevent blockage.
