Description

Technical Field

[0001] This utility model relates to the field of soil measurement technology, specifically a portable multi-parameter measuring instrument. Background Technology

[0002] Soil measurement is a process of assessing the physical and chemical properties and biological activity of soil through scientific methods. A multi-parameter soil measuring instrument is a high-tech device that integrates multiple detection technologies. It can quickly and accurately measure multiple key parameters in the soil, providing important support for agricultural production, environmental monitoring and other fields. It can simultaneously measure multiple indicators such as soil moisture, temperature, salinity, pH value, nitrogen, phosphorus and potassium nutrient content, as well as heavy metal content, to meet the detection needs of different scenarios.

[0003] Existing portable multi-parameter measuring instruments consist of a main body and a detection probe. The detection probe comprises multiple probes, which need to be inserted into the soil during measurement. However, the presence of stones in the soil can easily damage the probes, making it inconvenient to test the probes with a guide rod before insertion. Therefore, we propose a portable multi-parameter measuring instrument. Utility Model Content

[0004] The purpose of this invention is to provide a portable multi-parameter measuring instrument that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable multi-parameter measuring instrument, comprising a multi-parameter measuring instrument body, wherein the multi-parameter measuring instrument body is connected to a movable block via a wire, wherein a plurality of evenly distributed probes are fixedly connected to one side wall of the movable block, and a plurality of evenly distributed insert rods are connected to the other side wall of the movable block;

[0006] The movable block is mounted on a fixed frame. A sliding block is provided in the inner cavity of the fixed frame. A servo motor is fixedly mounted on one side wall of the sliding block. The drive shaft of the servo motor movably passes through the sliding block and is fixedly connected to the movable block. A strip-shaped hole is opened on one side wall of the fixed frame. A drive assembly is installed in the strip-shaped hole. The drive assembly is used to drive the sliding block to move.

[0007] By adopting the above technical solution, the device is first taken outdoors. During measurement, the servo motor drives the movable block to flip, so that the probe faces downward. Then, the drive component drives the sliding block to move, so that the probe is inserted into the soil to detect whether there are stones in the soil. If there are stones, the device is moved to continue detection. When there are no stones, the movable block is reset, and then the servo motor drives the movable block to flip again, so that the probe faces downward. Then, the movable block is moved again, so that the probe is inserted into the hole where the probe was inserted. This helps to avoid damage to the probe from impacts by stones.

[0008] In a preferred embodiment of this utility model, a fixing plate is fixedly connected to the tail end of the fixing frame, and the outer wall of the fixing plate is provided with a suitable through hole corresponding to the probe.

[0009] By adopting the above technical solution, when the probe and rod are inserted into the soil, they can penetrate through the hole, so that when the probe and rod are retracted, the soil on the probe and rod can be scraped off, thereby achieving cleaning.

[0010] In a preferred embodiment of this utility model, a lead screw motor is fixedly installed on the inner end face of the slotted hole, a lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor, the outer end of the lead screw is rotatably connected to the inner wall of the slotted hole, a suitable lead screw slider is fitted on the outer wall of the lead screw, and one side wall of the lead screw slider is fixedly connected to a sliding block.

[0011] By adopting the above technical solution, the lead screw motor can drive the lead screw to rotate, thereby driving the lead screw slider to move, which in turn drives the sliding block to move, and thus drives the probe and insertion rod to move.

[0012] In a preferred embodiment of this utility model, a connecting rod is connected to one end face of the fixing frame, and a handle is fixedly connected to the outer end of the connecting rod.

[0013] In a preferred embodiment of this utility model, one end of the connecting rod is fixedly connected to a second bolt post, and a second threaded hole is provided on the fixing frame, wherein the second bolt post and the second threaded hole engage.

[0014] In a preferred embodiment of this utility model, one end of the insertion rod is fixedly connected to a first bolt post, and the side wall of the movable block is provided with a first threaded hole corresponding to the first bolt post, and the first bolt post and the first threaded hole are threadedly engaged.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This application provides a portable multi-parameter measuring instrument that uses a servo motor to drive a movable block to rotate, so that the probe is inserted into the soil with the probe facing downwards to test for the presence of stones. When no stones are found, the instrument is flipped so that the probe faces downwards and can be inserted into the soil. This helps to avoid damage to the probe caused by the presence of stones.

[0017] When the probe and rod are inserted into the soil, they pass through the through hole, allowing the soil on the probe and rod to be scraped off when they retract, thus achieving automatic cleaning.

[0018] The fixed frame is connected to a connecting rod, so when using it, the staff can operate it by holding the handle, without having to bend over to insert the probe into the soil, which helps to reduce the labor intensity of the staff. Attached Figure Description

[0027] Please see Figure 1-3 The present invention provides a technical solution: a portable multi-parameter measuring instrument, including a multi-parameter measuring instrument body 1, a movable block 12 connected to the multi-parameter measuring instrument body 1 via a wire 11, a plurality of evenly distributed probes 13 fixedly connected to one side wall of the movable block 12, and a plurality of evenly distributed insertion rods 14 connected to the other side wall of the movable block 12.

[0028] The movable block 12 is mounted on the fixed frame 2. The inner cavity of the fixed frame 2 is provided with a sliding block 27. A servo motor 26 is fixedly mounted on one side wall of the sliding block 27. The drive shaft of the servo motor 26 passes through the sliding block 27 and is fixedly connected to the movable block 12. A strip-shaped hole is opened on one side wall of the fixed frame 2. A drive assembly is installed in the strip-shaped hole. The drive assembly is used to drive the sliding block 27 to move.

[0029] It should be noted that the measurement principle of the multi-parameter measuring instrument body 1 is based on multi-sensor fusion technology, which realizes the synchronous detection of key soil parameters through electrochemical, electromagnetic induction, thermosensitive and optical principles.

[0030] It should be understood that in actual use, the device is first taken outdoors. During measurement, the servo motor 26 drives the movable block 12 to flip, so that the probe 14 faces downward. Then, the drive component drives the sliding block 27 to move, so that the probe 14 is inserted into the soil to detect whether there are stones in the soil. If there are stones, the position is changed and the detection continues. When there are no stones, the movable block 12 is reset, and then the servo motor 26 drives the movable block 12 to flip again, so that the probe 13 faces downward. Then the movable block 12 is moved again, so that the probe 13 is inserted into the hole where the probe 14 was inserted. This helps to avoid the probe 13 being damaged by the impact of stones.

[0031] Furthermore, one end of the insertion rod 14 is fixedly connected to a first bolt post 15, and the side wall of the movable block 12 is provided with a first threaded hole corresponding to the first bolt post 15. The first bolt post 15 and the first threaded hole are threadedly engaged, which facilitates the disassembly of the insertion rod 14 and makes it easy to replace the insertion rod 14 after it is damaged.

[0032] like Figure 1 and 2 As shown; a fixing plate 24 is fixedly connected to the tail end of the fixing frame 2. The outer wall of the fixing plate 24 is provided with a suitable through hole 25 corresponding to the probe 13. When the probe 13 and the insertion rod 14 are inserted into the soil, they can pass through the through hole 25. Thus, when the probe 13 and the insertion rod 14 are retracted, the soil on the probe 13 and the insertion rod 14 can be scraped off, thereby achieving cleaning.

[0033] like Figure 1 and 2 As shown; a lead screw motor 21 is fixedly installed on the end face of the inner cavity of the strip hole, and a lead screw 22 is fixedly connected to the outer end of the drive shaft of the lead screw motor 21. The outer end of the lead screw 22 is rotatably connected to the inner wall of the strip hole. A suitable lead screw slider 23 is fitted on the outer wall of the lead screw 22. One side wall of the lead screw slider 23 is fixedly connected to the sliding block 27.

[0034] It should be understood that the lead screw motor 21 can drive the lead screw 22 to rotate, thereby driving the lead screw slider 23 to move, which in turn drives the slider block 27 to move, thereby driving the probe 13 and the insertion rod 14 to move.

[0035] like Figure 1 and 2 As shown; a connecting rod 3 is connected to one end of the fixed frame 2, and a handle 31 is fixedly connected to the outer end of the connecting rod 3.

[0036] It should be understood that the connecting rod 3 is connected to the fixed frame 2, so that when using it, the staff can operate it by holding the handle 31 without bending over to insert the probe 13 into the soil, which helps to reduce the labor intensity of the staff.

[0037] Furthermore, a second bolt post 32 is fixedly connected to one end of the connecting rod 3, and a second threaded hole is provided on the fixing frame 2. The second bolt post 32 and the second threaded hole engage, thereby making the connecting rod 3 detachable. This effectively reduces the size of the device when it is not in use, making it convenient to carry and store.

[0038] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the specific embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
