Description

Technical Field

[0001] The present invention relates to the technical field of agricultural environment monitoring, and particularly to a smart agricultural environment monitoring device. Background Technique

[0002] Agricultural environment monitoring is a process of intermittently or continuously monitoring and measuring certain representative values of agricultural environment quality with the pollutants in the agricultural environment and their harm to agricultural organisms as the core. The representative values of agricultural environment quality include the concentration of pollutants, energy, pollution intensity, their changes, and the impacts on the environment, etc. Agricultural environment monitoring is divided into routine monitoring, special-purpose monitoring, and research monitoring.

[0003] Since the pesticides used in agriculture are excessive nowadays, the degree of soil pollution by pesticide residues in some agricultural areas has been increasing year by year. Therefore, special-purpose monitoring is required. Conventional monitoring methods require manual sampling and testing of soil specimens at the same monitoring location regularly. However, due to the damage to the soil structure caused by humans, it is easy to cause errors in detection.

[0004] In view of the special-purpose monitoring link, how to improve the positioning and accurate and low-error monitoring of pesticide residue pollution of polluted agricultural soil is the technical difficulty to be solved by the present invention. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] To this end, the technical solution adopted by the present invention is as follows: An intelligent agricultural environment monitoring device, comprising a load-bearing mechanism, a testing mechanism and a fixed-point sampling mechanism. The load-bearing mechanism includes a meteorological instrument column, a main clamp installed in the outer annular groove of the meteorological instrument column, a sub-clamp located at the outer end of the main clamp, a core rod movably installed between the main clamp and the sub-clamp, two tension springs respectively connected to the inner cavities of the main clamp and the sub-clamp, and a driving runner installed inside the sub-clamp. The testing mechanism includes a protective component located outside the meteorological instrument column, a beam-positioning end tube installed inside the driving runner, a slider installed inside the protective component, a sealing door inserted on the protective component, two backing plates respectively connected to the protective component and the meteorological instrument column, two guide rods connected to the two backing plates, a cross tube movably installed on the two guide rods, and a main spring located inside the cross tube. The protective component includes a housing, an air duct installed in the horizontal hole on the outer wall of the housing, a photovoltaic panel connected to the top of the air duct, a positioning member installed inside the air duct, and a motor located inside the air duct and clamped in the middle of the positioning member. The fixed-point sampling mechanism includes a sleeve installed at the bottom of the housing, a core tube inserted inside the sleeve, a lead screw movably installed at the top of the core tube, a nut threadedly connected to the lead screw, a traction component movably installed on the sleeve, a collar installed at the bottom of the sleeve, four vane plates movably connected to the collar, and a plurality of auxiliary springs connected between the collar and the vane plates. The traction component includes a loop buckle movably installed in the annular hole at the top of the sleeve, an elastic telescopic rod connected to the outer wall of the loop buckle, and a plurality of cables connected to the loop buckle.

[0007] In a preferred example of the present invention, it can be further configured that: the driving runner is composed of a vertical pipe, a rocker and a gear disc, and an eccentric turntable is provided at the top end of the rocker.

[0008] By adopting the above technical solution, by rotating the grip rod on the eccentric turntable, at this time the rocker will drive the gear disc to rotate, and the nut meshing with the outside of the gear disc can drive the lead screw to rotate up or down, so as to realize the stable lifting and lowering of the sample soil stored in the inner cavity of the core tube.

[0009] In a preferred example of the present invention, it can be further configured that: a cover is inserted at the top of the beam-positioning end tube, and an inwardly concave annular hole groove is provided at the bottom end of the beam-positioning end tube. A vertical tube is provided at the top of the housing, and an annular hole adapted to the bottom end of the beam-positioning end tube is provided at the top of the vertical tube. Three sliding grooves are provided on the outer wall of the spherical end at the bottom of the housing.

[0010] By adopting the above technical solution, by opening an elliptical cavity inside the housing, when the core tube is lifted into the inner cavity of the housing, the monitoring personnel can detect the soil at different depths from the horizontal holes outside the core tube, and the air inside the housing cavity will circulate with the outside. At this time, the soil sampled and monitored at a fixed point can be kept in a constant state with the external environment to ensure accurate monitoring of the agricultural residues penetrating into the soil.

[0011] In a preferred embodiment of the present invention, it can be further configured that: a cavity is provided inside the horizontal pipe, which is clamped to the top studs of the two guide rods, and two nuts are respectively connected to both ends of the horizontal pipe.

[0012] By adopting the above technical solution, the distance between the two guide rods is controlled by controlling the two nuts. When it is necessary to monitor the soil near the ground where the weather station is located, the distance between the test mechanism and the weather station column can be adjusted to perform fixed-point detection on the soil near the weather station.

[0013] In a preferred embodiment of the present invention, it can be further configured that: vertical grooves distributed in a cross shape are provided on the outer wall of the sleeve, and vertical holes are provided on the inner wall of the sleeve. Uniformly distributed holes are provided on the outside of the core pipe, and slideways adapted to the inner end pads of the sliders are provided on both sides of the outside of the core pipe.

[0014] By adopting the above technical solution, after the spliced sleeve and core pipe are inserted into the fixed-point soil, the soil located in the inner cavity of the core pipe can be communicated with the external soil through the horizontal holes on its outside and the vertical grooves on the outer wall of the sleeve. At this time, the sample soil can maintain the same penetration state as the external soil.

[0015] In a preferred embodiment of the present invention, it can be further configured that: a sliding buckle is provided in the middle of the inner wall of the leaf plate, and two concave holes are provided on both sides of the top stud of the leaf plate.

[0016] By adopting the above technical solution, the sliding buckle is connected to the ring buckle by a cable. At this time, the sliding buckle movably installed in the inner wall groove of the leaf plate can be sealed against the bottom of the sleeve under the traction of the cable. At this time, the soil sealed in the inner cavity of the core pipe can ensure that the sample soil does not become loose and fall during regular monitoring.

[0017] By adopting the above technical solution, the beneficial effects obtained by the present invention are as follows: 1. By providing a sleeve in the present invention, a core pipe capable of positioning and storing the sampled soil is inserted inside the sleeve, a screw rod that can be spirally lifted is movably installed at the top of the core pipe, and a ferrule is installed at the bottom of the screw rod. Multiple cables passing through the vertical holes in the inner wall of the sleeve are used to connect multiple leaf plates movably installed at the bottom of the ferrule. After the sleeve and the core pipe penetrate downward towards the soil at the sampling position, by lifting the entire lifting and traction assembly, at this time, the four leaf plates can seal the soil in the inner cavity of the core pipe at intervals. At this time, the soil on the outer wall of the sleeve will be communicated with the soil in the inner cavity of the core pipe to ensure the stable transfer of the penetration of agricultural residues in the soil in the inner cavity of the core pipe, so as to effectively ensure that the device can facilitate the monitoring personnel to perform regular and accurate detection on the sample soil at the same position, thereby reducing the problem of errors in the detection data caused by different detection locations.

[0018] 2. The present invention installs a shell on the top of the casing that can lift the sample soil sealed at a fixed point, installs an air duct in the horizontal hole of the outer wall of the casing, and arranges a motor on the inner side of the air duct that can circulate the air in the inner cavity of the casing with the outside air. The nut movably installed between the casing and the bundle end tube cooperates with the spiral transmission of the screw rod. When the control driving wheel is rotated, the nut movably installed between the bundle end tube and the casing can control the free lifting and lowering of the screw rod and the core tube along the inner cavity of the casing, so as to facilitate the lifting and lowering of the sample soil sealed in the inner cavity of the core tube at a stable point, so as to avoid the sample soil from falling during the lifting process.

[0028] By rotating the grip rod on the eccentric turntable, at this time the rocker will drive the gear disc to rotate, and the nut 340 meshing with the outside of the gear disc can drive the lead screw 330 to rotate and lift or lower, so as to realize the stable lifting and lowering of the sample soil stored in the inner cavity of the core tube 320.

[0029] Embodiment Three: As shown in combination with Figures 5-7 shown, on the basis of Embodiment One, a cover is inserted at the top of the beam-positioning end tube 220, and an inwardly concave annular hole groove is provided at the bottom end of the beam-positioning end tube 220. A vertical tube is provided at the top of the housing 211, and an annular hole adapted to the bottom end of the beam-positioning end tube 220 is provided at the top of the vertical tube.

The horizontal tube 260 is internally provided with a cavity for clamping the top end heads of the two guide rods 250, and two nuts are respectively connected to both ends of the horizontal tube 260.

[0030] An oval cavity is opened inside the outer shell 211. After the core tube 320 is lifted into the inner cavity of the outer shell 211, the monitoring personnel can detect the soil at different depths through the horizontal holes outside the core tube 320. The air in the inner cavity of the outer shell 211 will circulate with the outside world, and the soil subjected to fixed-point sampling and monitoring can maintain a constant state with the external environment. At this time, it can be ensured that the agricultural residues infiltrated into the soil are accurately monitored. At the same time, by controlling two nuts, the distance between the two guide rods 250 is controlled to expand. When it is necessary to monitor the soil near the weather station, the distance between the test mechanism 200 and the weather station column 110 can be adjusted to perform fixed-point detection on the soil near the weather station.

[0031] Example 4: In combination Figures 8-12 As shown, on the basis of Example 1, vertical grooves distributed in a cross shape are opened on the outer wall of the sleeve 310, and vertical holes are opened on the inner wall of the sleeve 310. Uniformly distributed holes are opened on the outside of the core tube 320, and sliding grooves adapted to the inner end pads of the sliders 230 are opened on both sides of the outside of the core tube 320. A sliding buckle is opened in the middle of the inner wall of the vane 360, and two concave holes are opened on both sides of the top stud of the vane 360.

[0032] After the spliced sleeve 310 and core tube 320 are inserted into the fixed-point soil, the soil in the inner cavity of the core tube 320 can be communicated with the external soil through the horizontal holes outside it and the vertical grooves on the outer wall of the sleeve 310. At this time, the sample soil can maintain the same penetration state as the external soil. The sliding buckle is connected to the loop buckle 351 through the cable 353. The sliding buckle movably installed in the inner wall groove of the vane 360 can be sealed against the bottom of the sleeve 310 under the traction of the cable 353, so as to ensure that the soil sealed in the inner cavity of the core tube 320 can ensure that the sample soil does not loosen and fall during regular monitoring.

[0033] Working principle and usage process of the present invention: Firstly, a plurality of auxiliary springs 370 are used to connect four vane plates 360 to the bottom of the ferrule 380. At this time, the ends of the tops of the four vane plates 360 are movably installed in the rectangular slot holes on the inner wall of the bottom surface of the ferrule 380. Then, the bottom end of the cable 353 is used to connect the sliding buckle in the middle of the inner wall of the vane plate 360. At this time, the cable 353 penetrates through the vertical hole in the inner wall of the sleeve 310. At this time, the top end of the cable 353 is connected to the ring buckle 351. At this time, the three elastic telescopic rods 352 installed on the outer wall of the ring buckle 351 penetrate through the arc-shaped chute at the bottom of the housing 211. Then, the end of the bottom of the screw rod 330 is movably installed on the top of the core tube 320. At this time, the assembled core tube 320 penetrates through the inner cavity of the sleeve 310. At this time, the top of the assembled sleeve 310 is installed in the port at the bottom of the housing 211, and the nut 340 threaded on the top of the screw rod 330 is movably installed between the vertical tube at the top of the housing 211 and the bottom of the beam positioning end tube 220. The air duct 212 installed in the horizontal hole on the outer wall of the housing 211 cooperates with the two positioning members 214 to fix the motor 215. At this time, the turbine blades at the outer end of the motor 215 penetrate into the cavity of the air duct 212. At this time, the photovoltaic panel 213 is electrically connected to the motor 215. The assembled protection component 210 as a whole is connected by a backing plate 280, a combined guide rod 250 and a cross tube 260. At this time, the backing plate 280 installed at the bottom end of the other guide rod 250 is installed on the meteorological instrument column 110. At this time, the device can control the distance between the protection component 210 and the meteorological instrument column 110 by adjusting the nuts at both ends of the cross tube 260, and the main clamp 120 and the sub-clamp 150 are respectively connected by the core rod 130 and the two tension springs 140. At this time, the combined main clamp 120 and sub-clamp 150 connect the meteorological instrument column 110 and the beam positioning end tube 220. At this time, the drive runner 160 movably installed in the sub-clamp 150 through the riser can drive the nut 340 to rotate. At this time, the soil inserted into the inner cavity of the core tube 320 can be lifted upward. At the same time, the three traction components 350 are controlled to lift upward, and the four vane plates 360 pulled by the cable 353 can provide safety protection for the soil inserted into the inner cavity of the core tube 320. At this time, the soil inside the core tube 320 can facilitate the detection personnel to regularly monitor the degree of soil pollution in the area.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
