Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and more specifically, to a soil organic matter testing device. Background Technology

[0002] The main purpose of soil organic matter testing devices is multi-element detection. Soil organic matter measuring instruments have the ability to simultaneously detect multiple trace elements, including but not limited to potassium, nitrogen, phosphorus, iron, zinc, copper, and manganese, as well as other heavy metal elements. This multi-functionality helps agricultural producers and researchers to fully understand the content of various important elements in the soil.

[0003] In existing technologies, when organic matter detection devices test soil, the device probe needs to be inserted into a designated location in the soil. However, after the probe is inserted, soil remains at other depths, making it difficult to achieve high-precision detection at the designated depth and resulting in poor detection accuracy. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a soil organic matter detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil organic matter testing device, comprising a testing needle rod, two semi-inserted shells, and two connecting sliders, wherein the two semi-inserted shells are respectively fixed to both sides of the testing needle rod, and the two connecting sliders are respectively fixed to the top of the two semi-inserted shells, characterized in that: the inner wall of the connecting slider is provided with a deep extension component; the deep extension component includes a screw rod disposed on the inner wall of the connecting slider, both connecting sliders are threadedly connected to the screw rod, a sleeve frame is slidably connected to the outer wall of the connecting slider, and a reduction motor for driving the screw rod to rotate is fixedly installed on one side of the sleeve frame; a linkage block is welded to one side of the sleeve frame, and a telescopic rod is fixedly connected to one side of the linkage block, and the telescopic end of the telescopic rod is connected to the top of the linkage block.

[0006] Preferably, the output end of the geared motor is coaxially connected to one end of the screw, and the threads on both sides of the screw are opposite and symmetrically arranged, so that the tight closing and separation of the semi-insertion shell can be achieved through the arrangement of the screw.

[0007] Preferably, a sleeve connector is fixedly connected to the outer wall of the telescopic rod, and the telescopic end of the telescopic rod passes through the sleeve connector. A connecting wire is fixedly connected to one side of the sleeve connector, and a soil quality tester is fixedly installed at the top of the connecting wire. A button is installed on one side of the soil quality tester for testing the soil and controlling the telescopic rod and the reduction motor.

[0008] Preferably, a probe is fixedly connected to the bottom end of the detection needle rod, and the cross-sectional area of ​​the top end of the probe is larger than the cross-sectional area of ​​its bottom end, so that the probe can be inserted into the bottom position of the inner wall of the hole shape, and the organic quality test of the soil can be performed.

[0009] This invention achieves the separation and closure of the semi-insertion shell through the setting of the screw, avoiding the semi-insertion shell from being impacted and separating on its own during the insertion into the soil. The screw carries two linkage blocks upward through the telescopic rod, exposing the probe.

[0010] Preferably, each of the two semi-insertion shells has a support column welded to its outer side, and a guide impact assembly is installed at the top of the outer wall of the support column; the guide impact assembly includes a guide post fixedly disposed at the top of the outer wall of the support column; a gripping collar is slidably connected to the outer wall of the guide post, a rubber ring is bonded to the bottom end of the gripping collar, and a counterweight ring is welded to the top of the gripping collar; a limit block is welded to the top of the guide post, the limit block is used to limit the gripping collar, the inner wall of the rubber ring is slidably connected to the outer wall of the guide post, and the cross-sectional shape of the counterweight ring and the rubber ring is both circular. The guide impact assembly facilitates the insertion of the semi-insertion shell into the ground.

[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] As attached Figure 1-4 The soil organic matter testing device shown has a penetration extension component. The penetration extension component allows the uncontaminated probe 13 to be inserted into the bottom of the inner wall of the aperture, thus enabling organic matter testing of the soil and improving the accuracy of the test. The specific structure of the penetration extension component is as follows.

[0021] In this embodiment, as shown in the appendix Figure 1-3 As shown, the extended assembly includes a screw 4 disposed on the inner wall of the sleeve slider 3. Both sleeve sliders 3 are threadedly connected to the screw 4. A sleeve frame 5 is slidably connected to the outer wall of the sleeve slider 3. A reduction motor 6 for driving the screw 4 to rotate is fixedly installed on one side of the sleeve frame 5. A linkage block 7 is welded to one side of the sleeve frame 5. A telescopic rod 8 is fixedly connected to one side of the linkage block 7, and the telescopic end of the telescopic rod is connected to the top of the linkage block. The output end of the reduction motor 6 is coaxially connected to one end of the screw 4. The two threads on the outer wall of the screw 4 are opposite and symmetrically arranged. This utility model realizes the separation and closure of the semi-insertion shell through the setting of the screw, avoiding the semi-insertion shell from being impacted and separating itself during the insertion into the soil. The telescopic rod causes the screw to carry the two linkage blocks upward, exposing the probe.

[0022] In this embodiment, when using the soil organic matter testing device, two half-insertion shells 2 are inserted downwards. After the half-insertion shells 2 are inserted to a specified depth in the soil, the reduction motor 6 is started. The reduction motor 6 drives the screw 4 to rotate. The screw 4 rotates inside the sleeve frame 5. The screw 4 drives the two sleeve sliders 3 to move away from each other under the action of the threads. In this way, the distance between the two sleeve sliders 3 increases. The two sleeve sliders 3 respectively carry the two half-insertion shells 2, and the distance between them increases. The two half-insertion shells 2 expand inside the soil to form a hole. Then, the telescopic rod 8 is started to move upwards. The telescopic rod 8 drives the linkage block 7 to move upwards. The linkage block 7 carries the sleeve frame 5 to move the screw 4 upwards.

[0023] The screw 4 carries two linkage blocks 7 upwards, and the two linkage blocks 7 carry two half-insertion shells 2 upwards, thus exposing the probe 13. During the insertion process, the probe 13 is protected by the two half-insertion shells 2 to prevent the probe 13 from contacting other soil and causing pollution. The downward moving detection needle rod 1 carries the probe 13 downwards, and the probe 13 is inserted into the bottom position of the inner wall of the hole, so that the organic quality of the soil can be tested.

[0024] In this embodiment, as shown in the appendix Figure 1-4 As shown, a connecting wire 14 is fixedly connected to one side of the socket 11, and a soil quality analyzer 15 is fixedly installed at the top of the connecting wire 14. A button 12 is embedded in one side of the soil quality analyzer 15 for soil testing and controlling the telescopic rod and the reduction motor. The socket 11 is connected to the connecting wire 14, and the detection needle rod 1 is connected to the socket 11. The detection needle rod 1 is connected to the probe 13 to realize the soil organic quality testing operation of the probe 13. The probe 13 is fixedly connected to the bottom end of the detection needle rod 1, and the cross-sectional area of ​​the top end of the probe 13 is larger than the cross-sectional area of ​​its bottom end. This allows the probe 13 to be inserted into the bottom position of the inner wall of the hole to perform the soil organic quality testing operation.

[0025] In this embodiment, as shown in the appendix Figure 4 As shown, each of the two semi-insertion shells 2 has a support column 16 welded to its outer side. A guide impact assembly is installed at the top of the outer wall of the support column 16. The guide impact assembly includes a guide column 17 fixedly installed at the top of the outer wall of the support column 16. A gripping collar 18 is slidably connected to the outer wall of the guide column 17. A rubber ring 19 is bonded to the bottom end of the gripping collar 18. A counterweight ring 20 is welded to the top of the gripping collar 18. A limiting block 10 is welded to the top of the guide column 17. The limiting block 10 is used to limit the gripping collar 18. The inner wall of the rubber ring 19 is slidably connected to the outer wall of the guide column 17. The cross-sectional shape of the counterweight ring 20 and the rubber ring 19 is circular.

[0026] In this embodiment, when the semi-inserted shell 2 is inserted into the soil, the hand holds the outer wall of the holding collar 18 and impacts the holding collar 18 from top to bottom. The holding collar 18 is vertically limited by the limiting block 10. At the same time, the holding collar 18 carries the counterweight ring 20 and moves downward. The holding collar 18 drives the rubber ring 19 to move downward. The rubber ring 19 and the holding collar 18 impact downward along the outer wall of the guide post 17. In this way, the support post 16 impacts downward and drives the semi-inserted shell 2 to move downward, and the semi-inserted shell 2 is inserted into the soil.
