Abstract
Description
Technical Field
[0001] This utility model relates to the field of reconstructed soil technology, specifically a reconstructed soil moisture measuring device. Background Technology
[0002] In mining areas, land is severely damaged by mining activities. Soil reconstruction can rebuild a suitable soil environment, providing a basis for vegetation growth and restoring the land's productivity. This allows previously abandoned land to be reused for agriculture, forestry, or other land uses.
[0003] However, existing technologies still have the following problems:
[0004] First, most existing reconstructed soil moisture measuring devices are not well adapted to different soil types. Most traditional devices use direct insertion measuring components, which are difficult to insert smoothly when faced with reconstructed soil that is hard, compacted, or contains large impurities. For example, reconstructed soil after mining often contains a large number of rock fragments and compacted soil clods. Forced insertion can easily damage the measuring components, such as bending or breaking the probe and cracking the sensor housing, making it impossible to obtain accurate measurement data and severely limiting the application of the device in complex soil environments.
[0005] Secondly, existing soil moisture measuring devices are usually inconvenient to install and maintain. They are mostly integrated designs with tightly connected components and lack convenient disassembly structures. When the measuring components malfunction, such as sensor aging, circuit damage, or when maintenance operations such as cleaning or calibration are required, the disassembly process is extremely cumbersome and often requires the use of various professional tools, consuming a lot of time and manpower.
[0006] To address the aforementioned problems, the inventors proposed a reconstructed soil moisture measuring device. Utility Model Content
[0007] In order to solve the problems of poor adaptability and poor maintainability of reconstructed soil moisture measuring devices, the purpose of this utility model is to provide a reconstructed soil moisture measuring device.
[0008] To solve the above technical problems, the present invention adopts the following technical solution: a reconstructed soil moisture measuring device, comprising a base plate, an adjustment frame and a support on the upper surface of the base plate, and a measuring component inside the support. The lower surface of the adjustment frame is fixedly connected to the base plate. A lead screw is rotatably mounted inside the adjustment frame. A servo motor is fixedly mounted on the upper surface of the adjustment frame, and the output end of the servo motor passes through the adjustment frame and is fixedly connected to the lead screw. A lifting block is threaded onto the outer surface of the lead screw. A sleeve block is fixedly mounted on both sides of the lifting block. A lifting frame is detachably connected to one side of the sleeve block. A vertical plate is bolted to the outer side of the sleeve block, and the vertical plate is fixedly connected to the lifting frame. A DC motor is mounted on the upper surface of the lifting frame. The output end of the DC motor passes through the lifting frame and is fixedly mounted with a threaded column. A conical drill bit is fixedly mounted at the lower end of the threaded column. A circular groove for use with the threaded column and the conical drill bit is opened on the upper surface of the base plate.
[0009] Preferably, an electric push rod is fixedly provided on the upper surface of the bracket, and the output end of the electric push rod passes through the bracket and is fixedly connected to the measuring component. A through groove for use with the measuring component is provided on the upper surface of the base plate. The bracket and the base plate are detachably connected. Slots are symmetrically provided on both sides of the through groove. A retaining plate is symmetrically fixed on the lower surface of the bracket and is engaged in the corresponding slot. Mounting blocks are symmetrically fixed on both sides of the base plate and are connected to the base plate by bolts.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. In the case of reconstructed soils that are hard and difficult to insert the measuring components directly, this utility model first creates conditions for the subsequent insertion of the measuring components by drilling holes with a threaded column and a conical drill bit, which broadens the applicability of the device under different soil conditions and enables accurate measurement of moisture in more complex soil environments.
[0012] 2. The bracket and base plate in this utility model are detachably connected by a card plate and a card slot, and the mounting block is bolted to the base plate. This facilitates the disassembly, assembly and maintenance of the measuring equipment when needed, reduces maintenance costs and improves the service life of the device. Attached Figure Description

[0018] 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.
[0019] Example: Figure 1-3As shown, this utility model provides a reconstructed soil moisture measuring device, including a base plate 1. Support legs 11 are symmetrically fixed to the lower surface of the base plate 1, and support rods 12 are symmetrically fixed to the upper surface of the base plate 1. A handle 13 is fixed to one upper end of each support rod 12. An adjustment frame 2 and a bracket 3 are provided on the upper surface of the base plate 1. A measuring component 31 (specifically a capacitive soil moisture sensor, manufacturer: Spectrum, USA, model: SMEC-300) is provided inside the bracket 3. The lower surface of the adjustment frame 2 is fixedly connected to the base plate 1. A lead screw 21 is rotatably mounted inside the adjustment frame 2. A servo motor 22 is fixedly mounted on the upper surface of the adjustment frame 2, and the output end of the servo motor 22 passes through the adjustment frame 2 and is fixedly connected to the lead screw 21. The servo motor 22 is an AC servo motor of model ECMA-C20604, and its output end is fixedly connected to the lead screw 21 via a coupling. A lifting block 23 is threaded onto the outer surface of the lead screw 21. Both sides of the device are fixedly provided with sleeve blocks 24. Slide bars 211 are symmetrically fixed inside the sleeve blocks 24 and are locked on one side surface of the adjustment frame 2. A lifting frame 25 is detachably connected to one side of the sleeve blocks 24. A vertical plate 212 is bolted to the outside of the sleeve blocks 24 and is fixedly connected to the lifting frame 25. Limiting posts 29 are symmetrically fixed on the upper surface of the base plate 1 and penetrate the lifting frame 25. The user holds the handle 13 and places the device stably in the reconstructed soil area to be measured by the support legs 11. The servo motor 22 is started and drives the lead screw 21 to rotate. Since the lifting block 23 is threadedly connected to the lead screw 21 and the slide bar 211 is locked on one side surface of the adjustment frame 2, the rotation of the lifting block 23 is restricted, so that the lifting block 23 can only move up and down along the axis of the lead screw 21. As the lifting block 23 descends, the sleeve blocks 24, the vertical plate 212 and the lifting frame 25 connected to it descend synchronously.
[0020] A DC motor 26 is provided on the upper surface of the lifting frame 25. A side guard plate 210 is fixedly provided on one side of the lifting frame 25, and the side guard plate 210 is fixedly connected to the DC motor 26. The output end of the DC motor 26 passes through the lifting frame 25 and is fixedly provided with a threaded post 27. A conical drill bit 28 is fixedly provided at the lower end of the threaded post 27. A circular groove is opened on the upper surface of the base plate 1 to cooperate with the threaded post 27 and the conical drill bit 28. When the lifting frame 25 descends to a certain position, the DC motor 26 is started. The output end of the DC motor 26 drives the threaded post 27 to rotate, which in turn causes the conical drill bit 28 at the lower end to rotate at high speed. Under the continuous descent of the lifting frame 25, the conical drill bit 28 passes through the circular groove and gradually drills into the soil to perform drilling operations. The side guard plate 210 plays a protective role to prevent soil from splashing during the drilling process.
[0021] An electric push rod 32 is fixedly mounted on the upper surface of the bracket 3. The bracket 3 is welded from aluminum alloy profiles with a thickness of 4mm and is shaped like a "door". The output end of the electric push rod 32 passes through the bracket 3 and is fixedly connected to the measuring component 31. A through groove 36 is opened on the upper surface of the base plate 1 to facilitate the passage of the measuring component 31. The bracket 3 and the base plate 1 are detachably connected. Slots 34 are symmetrically opened on both sides of the through groove 36. A retaining plate 35 is symmetrically fixed on the lower surface of the bracket 3, and the retaining plate 35 is engaged in the corresponding retaining groove 34. The two sides of the base plate 1 are symmetrically fixed. The device is equipped with a mounting block 33, which is connected to the base plate 1 by bolts. After drilling, the bracket 3 is engaged with the slots 34 on both sides of the through groove 36 via the clamping plate 35 and installed on the base plate 1. Hold the handle 13 to lift the device, aim at the drilled hole so that the measuring component 31 is directly above the hole. The electric push rod 32 on the bracket 3 pushes the measuring component 31 downward. The measuring component 31 passes through the through groove 36 and enters the drilled hole to measure soil moisture. The electric push rod 32 can precisely control the insertion depth of the measuring component 31 to meet different measurement needs.
[0022] Working principle: The user holds the handle 13 and places the device stably in the reconstructed soil area to be measured by the support leg 11. The servo motor 22 is started and drives the lead screw 21 to rotate. Since the lifting block 23 is threadedly connected to the lead screw 21 and the slide bar 211 is locked on one side of the adjustment frame 2, the rotation of the lifting block 23 is restricted, so that the lifting block 23 can only move up and down along the axis of the lead screw 21. As the lifting block 23 descends, the sleeve block 24, the vertical plate 212 and the lifting frame 25 connected to it descend synchronously.
[0023] When the lifting frame 25 descends to a certain position, the DC motor 26 is started. The output end of the DC motor 26 drives the threaded column 27 to rotate, which in turn causes the tapered drill bit 28 at the lower end to rotate at high speed. Under the continuous descent of the lifting frame 25, the tapered drill bit 28 passes through the circular groove and gradually drills into the soil to perform drilling operations. The side guard plate 210 plays a protective role to prevent soil from splashing during the drilling process.
[0024] After drilling, the bracket 3 is engaged with the slots 34 on both sides of the through groove 36 via the clamping plate 35 and installed on the base plate 1. Hold the handle 13 to lift the device, aim at the drilled hole so that the measuring component 31 is directly above the hole, and the electric push rod 32 on the bracket 3 pushes the measuring component 31 downward. The measuring component 31 passes through the through groove 36 and enters the drilled hole to measure soil moisture. The electric push rod 32 can precisely control the insertion depth of the measuring component 31 to meet different measurement needs.
[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
