Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a soil probe with an improved connection structure. Background Technology

[0002] Plant growth requires a favorable soil environment. Changes in soil temperature, moisture content, and pH play a crucial role in crop growth, and proper control of soil parameters can promote crop growth. Good temperature and humidity, along with suitable soil properties, ensure that plants grow in an ideal soil environment, leading to increased yields and income. Accurate monitoring of soil temperature, humidity, and properties allows for timely assessment of crop growth conditions and timely intervention to address unsuitable soil conditions, thereby improving the quality of agricultural production. Current technologies typically use soil testing probes inserted into the soil for detection.

[0003] However, existing soil probes typically use a bayonet-type connection structure. While this structure is simple and easy to operate, it has the following shortcomings in practical use:

[0004] Poor connection stability: Bayonet-type connections are prone to loosening, causing the probe to get stuck in the soil when testing, break when pulled out, and affecting measurement accuracy.

[0005] Insufficient sealing: After prolonged insertion and removal, the connection point is prone to loosening, allowing water and dust to enter, which affects the lifespan of the probe's internal wires.

[0006] Durability needs improvement: The needle body material is not strong enough, making it easy to bend and deform, which affects the service life of the probe.

[0007] Assembly efficiency is low: the conductive wires are easily broken during installation, resulting in a high rework rate.

[0008] There is a need for a new type of soil probe with an improved connection structure that can solve the problems mentioned above. Utility Model Content

[0009] This invention provides a soil probe with an improved connection structure. By technically modifying existing soil testing devices, it solves the problems of poor connection stability, insufficient sealing, and low durability of existing testing probes.

[0011] An improved connection structure for a soil probe includes a needle tip, a hollow connecting sleeve, a needle body, an intermediate connector, and a conductive wire. The soil probe is arranged from top to bottom with the needle body, the hollow connecting sleeve, and the needle tip. The needle tip is inserted into the soil and is detachably connected to the needle body, the hollow connecting sleeve, and the needle tip via the intermediate connector. The conductive wire passes through the needle body and the hollow connecting sleeve until it is electrically connected to the needle tip.

[0012] Preferably, the intermediate connector includes a first connector and a second connector, wherein the first connector is connected between the needle tip portion and the hollow connecting sleeve, and the second connector is connected between the hollow connecting sleeve and the needle body portion.

[0013] Preferably, the intermediate connector includes a connector body, an upper threaded post, and a lower threaded post. The upper and lower threaded posts are respectively fixed on the upper and lower sides of the connector body. The connector body, the upper threaded post, and the lower threaded post are provided with through holes at their centers. The upper and lower threaded posts are provided with external threads. The needle tip, the hollow connecting sleeve, and the needle body are threadedly connected to the intermediate connector.

[0014] Preferably, the connector body, the upper threaded post, and the lower threaded post are integrally formed.

[0015] Preferably, the connector body has annular sealing grooves on its upper and lower sides, and a silicone sealing ring is installed in the annular sealing groove.

[0016] Preferably, the upper and lower threaded posts are provided with longitudinal section cuts, which are used to allow conductive wires to pass through.

[0017] Preferably, the needle tip and the hollow connecting sleeve are made of a conductive and corrosion-resistant alloy material.

[0029] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0030] Please see Figure 1-3 As shown, this utility model provides a soil probe with an improved connection structure, including a needle part 1, a hollow connecting sleeve 2, a needle body part 3, an intermediate connector 4, and a conductive wire 5. The soil probe is arranged from top to bottom with the needle body part 3, the hollow connecting sleeve 2, and the needle part 1. The needle part 1 is inserted into the soil and the needle part 1, the hollow connecting sleeve 2, and the needle part 1 are detachably connected through the intermediate connector 4. The conductive wire 5 passes through the needle body part 3 and the hollow connecting sleeve 2 until it is electrically connected to the needle part 1.

[0031] Furthermore, in order to facilitate the assembly of the connecting needle body part 3 and the needle tip part 1, the intermediate connecting member 4 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is connected between the needle tip part 1 and the hollow connecting sleeve 2, and the second connecting member 42 is connected between the hollow connecting sleeve 2 and the needle body part 3.

[0032] Furthermore, to facilitate the detachable connection of the needle tip portion 1 and the needle body portion 3, and to ensure a more secure installation, the intermediate connector 4 includes a connector body 43, an upper threaded post 44, and a lower threaded post 45. The upper threaded post 44 and the lower threaded post 45 are respectively fixed on the upper and lower sides of the connector body 43, and a through hole is provided in the center of the connector body 43, the upper threaded post 44, and the lower threaded post 45. The upper threaded post 44 and the lower threaded post 45 are provided with external threads. The needle tip portion 1, the hollow connecting sleeve 2, and the needle body portion 3 are threadedly connected to the intermediate connector 4.

[0033] Furthermore, the connector body 43, the upper threaded post 44, and the lower threaded post 45 are integrally formed.

[0034] Furthermore, to achieve a better sealing effect, annular sealing grooves 431 are respectively provided on the upper and lower sides of the connector body 43, and silicone sealing rings 432 are installed in the annular sealing grooves 431. When the intermediate connector 4 is tightened with the needle part 1, the hollow connecting sleeve 2, or the needle body part 3, the silicone sealing rings 432 are compressed to form a tight sealing layer, effectively preventing water and dust from entering the probe, protecting the internal wires, and extending the probe's service life.

[0035] Furthermore, the upper threaded post 44 and the lower threaded post 45 are provided with longitudinal section cuts 46, which are used to allow the conductive wire 5 to pass through. These cuts allow the conductive wire 5 to pass smoothly through when the connector is tightened and to make electrical connection with the inner wall of the metal shell of the needle part 1, avoiding the wire from being squeezed or damaged.

[0036] Furthermore, the needle portion 1 and the hollow connecting sleeve 2 are made of a conductive and corrosion-resistant alloy material, such as aluminum, lead, or zinc alloy.

[0037] Furthermore, the needle body 3 is made of a high-strength, wear-resistant alloy. The needle body 3 can be made of aluminum alloy, copper, or zinc alloy, which improves the strength, durability, and wear resistance of the probe and prevents the probe from bending or deforming.

[0038] Furthermore, the outer side of the needle body 3 is also provided with scale markings to facilitate quick determination of the insertion depth during measurement.

[0039] When using, connect the needle part 1, hollow connecting sleeve 2, needle body part 3, and intermediate connecting piece 4 by thread and tighten.

[0040] Insert the probe into the soil to perform soil testing;

[0041] After use, pull the probe out of the soil and clean it thoroughly.

[0042] The needle part 1 can be designed as a replaceable structure, allowing for the selection of needles of different shapes and materials depending on different soil types or measurement needs.

[0043] This application provides a more stable connection. The threaded connection structure is more robust than the bayonet connection, effectively preventing the probe from loosening or shaking during use and improving measurement accuracy.

[0044] This application offers better sealing, with the hollow connecting sleeve 2 tightly threaded at the connection point, effectively preventing water and dust from entering the probe, protecting the internal wires, and extending the probe's service life.

[0045] This application offers greater durability. The needle body 3 is made of materials such as aluminum alloy, copper, and zinc alloy, which provides high strength, increases the product's wear resistance, prevents bending and deformation, and extends the probe's lifespan.

[0046] The needle tip 1 has better conductivity and corrosion resistance: The metal part of the needle tip 1 is made of aluminum, lead and zinc alloy to ensure the conductivity and corrosion resistance of the probe and adapt to various soil environments.

[0047] The installation is more efficient. During the installation process, you only need to manually connect the parts and then tighten them with a power drill. It is very simple and secure.
