Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling tool for plant protection. Background Art

[0002] Agricultural soil sampling for plant protection is used to assess soil characteristics, nutrient levels, and the plant growth environment, thereby implementing appropriate plant protection strategies. The sampling depth is determined based on the depth of plant root distribution and nutrient distribution needs. Typically, both surface soil (0-15 cm) and deep soil (15-30 cm or deeper) need to be sampled, necessitating soil sampling tools.

[0003] After searching, the announcement number CN212539708U is a soil sampling tool for agricultural plant protection. The utility model discloses a soil sampling tool for agricultural plant protection, including a soil-breaking tube, a drill bit and a fixture. The outer surface of the soil-breaking tube is fixedly connected to a handle, the outer surface of the soil-breaking tube is provided with a scale, the outer surface of the soil-breaking tube is fixedly connected to a drill bit, the upper surface of the soil-breaking tube is provided with a first through hole, the upper surface of the fixture is provided with a second through hole, and the outer surface of the soil-breaking tube is movably connected to a fixture. The soil sampling tool for agricultural plant protection, by providing a drill bit and a drill bit, can easily penetrate deep into the soil when encountering hard soil or soil with bricks. The drill bit rotating into the soil is much more convenient than knocking into the soil with an ordinary sampler, saving the staff's time and physical strength. By providing a sampling tube and a bolt, after sampling, the soil sample can be removed from the sampler and then collected, without having to use a knocking tool to make the sample come out, thus preserving the integrity of the sample.

[0004] Based on the above patent, by setting a drill blade and a drill bit, it is relatively easy to penetrate deep into the soil when encountering hard soil or soil with bricks. However, when encountering a relatively hard soil surface, the user needs to apply downward force while rotating the handle, which has certain requirements for operation. In addition, the support legs of the device are easy to tilt when the user uses the device to sample relatively hard soil. In response to this technical problem, this application proposes a plant protection soil sampling tool. Utility Model Content

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment of a plant protection soil sampling tool, comprising a cavity 1, the top of the cavity 1 is fixedly connected with a screw 5, the outer wall of the screw 5 is sleeved with a screw sleeve 4, the outer wall of the screw sleeve 4 is fixedly connected with a tripod 9, the top of the screw 5 is fixedly connected with a gripping member 6, the top of the gripping member 6 is provided with a force-applying member 8, the bottom end of the cavity 1 is fixedly connected with a soil-breaking tooth 10, the top of the gripping member 6 is provided with a through hole, the top of the screw 5 is provided with a through slot, the through hole is connected to the through slot, the interior of the cavity 1 is provided with a cavity, and the cavity is connected to the through slot; the bottom end of the screw sleeve 4 is provided with a positioning member 2, the outer wall of the positioning member 2 is fixedly connected with a fixing rod 3, the end of the fixing rod 3 away from the positioning member 2 is fixedly connected to the outer wall of the tripod 9, the positioning member 2 is connected to the tripod 9 through the fixing rod 3, and the inner wall specifications of the positioning member 2 are the same as those of the outer wall of the cavity 1;

[0025] Specifically, when sampling of relatively hard soil is required, the user can place both feet on the fixed rod 3 respectively, so that when rotating the grip 6, the stability provided by the tripod legs 9 and the downward force applied by the user's own weight prevent the soil-breaking teeth 10 from tilting the device when applying downward force, making the device more stable. The device has a simple structure, is suitable for single-person use, is easy to carry, and is easy to clean.

[0026] Reference Figure 1 and Figure 4 The bottom end of the tripod leg 9 is fixedly connected to a protective pad 14, and the bottom end of the protective pad 14 is fixedly connected to a plurality of fixed teeth 13;

[0027] Specifically, when a sampling location is selected, the tripod 9 is placed at the sampling point, and the fixing teeth 13 penetrate into the soil to fix the device and mark the location.

[0028] Reference Figure 1 and Figure 3 The inner wall of the cavity 1 is slidably connected with a rubber ring 12, the inner wall of the rubber ring 12 is fixedly connected with a soil discharge piece 11, the top of the soil discharge piece 11 is fixedly connected with a soil discharge rod 7, the top of the soil discharge rod 7 is fixedly connected to the bottom end of the force member 8, and the outer wall of the soil discharge rod 7 passes through the interior of the through hole and the interior of the through groove in sequence;

[0029] Specifically, when the soil needs to be removed, the soil can be removed by applying a downward force to the force-applying member 8. Since a rubber ring 12 is provided on the outer periphery of the soil-discharging member 11, all the soil inside the cavity 1 can be pushed out of the cavity 1 without any residue, thus avoiding the mixing of different soils, improving the soil purity, and improving the detection accuracy.

[0030] Working principle: First, place the device at the sampling point, and the fixed teeth 13 will penetrate into the soil to fix the device and mark the position. When sampling, the user can step on the fixed rod 3 with both feet, hold the holding piece 6 with both hands and rotate it. At this time, the screw 5 is driven by the holding piece 6 to rotate. Due to the presence of the screw sleeve 4, the screw 5 rotates downward and drives the cavity 1 to move downward, and finally the soil-breaking teeth 10 rotate and move downward to drill holes in the soil for sampling. When the soil needs to be removed, the soil can be removed by applying a downward force to the force-applying piece 8. Since a rubber ring 12 is provided on the outer periphery of the soil-discharging piece 11, all the soil inside the cavity 1 can be pushed out of the cavity 1.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
