Description

Technical Field

[0001] This invention relates to the field of soil environmental monitoring technology, and specifically to an in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments. Background Technology

[0002] To protect the environment and promote sustainable development, soil monitoring devices are typically installed in important agricultural areas. Soil environmental monitoring is an important measure to understand the status of soil environmental quality and aims to prevent and control soil pollution hazards. It involves the dynamic analysis and measurement of the degree and development trend of soil pollution, including current status surveys of soil environmental quality, surveys of regional soil environmental background values, investigations of soil pollution incidents, and dynamic observation of polluted soil. Areas for improvement in the use of soil environmental monitoring devices include: When using the soil environmental monitoring device, under normal circumstances, rotating the turntable drives the second bevel gear to rotate, which in turn drives the first bevel gear in the housing to rotate, which in turn drives the transmission shaft to rotate. This causes the disc to rotate inside the column, and the sliding block on the disc moves through the groove. The sliding block then drives the soil monitoring sensor to slide on the cross rail, allowing the monitoring needle on one side of the soil monitoring sensor to extend through the through hole and monitor the soil, thus improving the practicality of the device. However, when using the soil environmental monitoring device, there is only a sampling hole on the drill bit, and no soil collection component. It can only collect soil from the lower part of the device, which means that it cannot collect a large number of samples. The staff needs to collect and process the soil repeatedly. Moreover, soil is prone to falling during the collection process. Furthermore, the drill bit is prone to shaking during the collection process, making it difficult to collect samples stably and affecting the monitoring effect of the soil. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention is achieved through the following technical solution: an in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments, comprising a drilling device, a mounting plate, a controller, a display screen, a handle, and telescopic rods. The drilling device is inserted into the middle of the lower end of the mounting plate, and two telescopic rods are inserted into both sides of the lower end of the mounting plate. The two telescopic rods are symmetrically arranged on the left and right sides of the drilling device via the mounting plate. The upper end of the mounting plate is provided with a controller and a display screen, and the controller and display screen are electrically connected.

[0004] As a further optimization of the invention, the drilling device includes a sampling component, a docking rod, a clamping connector, and a connecting rod. The sampling component is fitted to the lower end of the connecting rod, and the end of the connecting rod away from the sampling component is inserted into the lower end of the docking rod. The top of the docking rod is fixedly connected to the clamping connector, and the clamping connector, docking rod, and connecting rod are sequentially connected and arranged on the same straight line.

[0005] As a further optimization of the invention, the sampling component includes a drill bit, a rotating component, a support rod, a collecting component, and a rotating cylinder. The drill bit is installed at the lower middle position of the rotating component, and the middle position of the rotating component is fitted with the rotating cylinder. The end of the rotating cylinder away from the rotating component is fixedly connected to the support rod, and the top of the support rod is vertically inserted into the lower middle position of the collecting component.

[0006] As a further optimization of the invention, the drilling device and four telescopic rods are installed parallel to each other at the bottom of the mounting plate. The operator moves the mounting plate to the corresponding position by pulling the handle, and places the sampling component on the drilling device against the position. The telescopic rods on both sides then provide support and leveling, allowing the sampling component to be vertically and stably placed into the corresponding position. The clamping joint, connecting rod, and connecting rod are connected in sequence to assist the sampling component in inserting into the soil. The drill bit on the sampling component and the rotating component cooperate to rotate and insert into the soil. Then, the collection component moves accordingly to collect and sample the soil.

[0007] As a further optimization of the invention, the telescopic rod is installed on the four sides of the mounting plate. The telescopic rod has a certain telescopic function and can be adjusted up and down in conjunction with one end of the drilling device, so that the drilling device can move down stably to collect samples.

[0008] As a further optimization of the invention, the top of the connector is fixedly inserted into the middle position of the bottom of the mounting plate, so that the docking rod and the connecting rod cooperate to vertically install the sampling component in the corresponding position, and the soil is sampled and collected through the sampling component.

[0009] As a further optimization of the invention, the top of the collecting component is connected to the connecting rod, so that the drill bit is perpendicular to the soil. The drill bit is mounted on the rotating component, and the rotating component is rotated and adjusted under the action of the rotating drum, thus drilling into the soil.

[0010] As a further optimization of the invention, the collection assembly includes a linkage plate, an extension rod, a retaining ring, a sampling tube, a retaining arc member, and a slide rail. There are four linkage plates, and all four linkage plates are slidably connected on the slide rails. The four slide rails are set on four corresponding extension rods, and a sampling tube is inserted into each of the four extension rods. The sampling tube is engaged with the retaining arc member, and half of the retaining arc member is fixedly connected to the extension rod, while the other half is fixedly connected to the linkage plate. The four extension rods are equidistantly and annularly inserted into the retaining ring.

[0011] As a further optimization of the invention, the retaining ring is fixedly connected to the top of the support rod, and the retaining ring moves on the slide rail through the linkage plate to fit against the sampling tube, thereby stably restricting the sampling tube on the extension rod for use.

[0012] As a further optimization of the invention, the sampling tube is provided with a collection cavity, a tube body, and an opening and closing assembly. The collection cavity is located in the middle of the inside of the tube body, and the opening and closing assembly is installed at the lower end of the tube body. The opening and closing assembly is located at the lower end of the tube body and is movably connected.

[0013] As a further optimization of the invention, the cylinder is inserted through the end of the extension rod, and the position of the cylinder is limited by locking the extension rod with a retaining element, so that the cylinder is less likely to shift or slip out during the sampling process.

[0014] As a further optimization of the invention, the opening and closing assembly includes a sliding head, a chuck, an inlet, an adjusting rod, and a closing baffle. There are five sliding heads, which are set on four adjusting rods. The five adjusting rods are equidistantly arranged in a ring on the chuck, and an inlet is provided in the middle of the chuck. Five closing baffles are provided on the inlet, and the five closing baffles are slidably connected by the sliding heads to form a circular structure on the inlet.

[0015] As a further optimization of the invention, the sliding head drives the closed baffle to slide on the adjusting rod, so that the five closed baffles slide outward through the sliding head, making the inlet directly visible, which helps the cylinder to sample the soil. After the cylinder has finished sampling, the closed baffle slides inward through the sliding head, so that the inlet closes and opens accordingly, effectively blocking the soil collected inside the cylinder.

[0016] As a further optimization of the invention, the rotating assembly includes a rotating shaft, a housing, a rotating adjustment component, helical blades, and insert rods. There are six rotating shafts, and insert rods are inserted into each of the six shafts. The six insert rods are equidistantly arranged in a ring on the housing and are slidably connected. Multiple helical blades are installed on the outside of the housing at equal intervals. The housing is engaged with the rotating adjustment component at the middle position, and the housing rotates through the rotating adjustment component.

[0017] As a further optimization of the invention, multiple curved spiral blades are arranged in a ring at equal intervals on the outside of the shell. The shell rotates clockwise under the action of the rotating adjustment component, and the multiple spiral blades rotate under the drive of the shell to loosen and spread the soil, which helps the collection component to move down to collect the soil. Beneficial effects

[0018] This invention provides an in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments, which has the following beneficial effects: In this invention, during the downward movement of the drilling device, the telescopic rod retracts inward simultaneously, pressing the sampling component on the drilling device against the position of use. The top of the clamping connector is fixedly inserted into the middle position of the bottom of the mounting plate, so that the connecting rod and the connecting rod cooperate to vertically install the sampling component in the corresponding position. The telescopic rods on both sides then play a supporting and leveling role, allowing the sampling component to be vertically and stably placed in the corresponding position. The clamping connector, connecting rod, and connecting rod are connected in sequence to constrain the sampling component to the same straight line, thereby assisting the sampling component to be vertically inserted into the soil, and the soil is sampled and collected through the sampling component.

[0019] This invention involves mounting a drill bit on a rotating assembly, which rotates and adjusts under the action of a rotating drum to drill into the soil. During rotation, a pivoting adjustment component at the center of the rotating assembly is fixedly connected to the drill bit. Simultaneously, the housing is also driven. Multiple curved spiral blades are equidistantly arranged in a ring on the outside of the housing. The housing rotates clockwise under the action of the pivoting adjustment component, and the multiple spiral blades rotate under the drive of the housing to loosen and disperse the soil. This facilitates the downward movement of the collection component to collect the soil, effectively assisting the drill bit in drilling the soil and preventing the drill bit from shaking during the drilling process. This ensures stable collection and sampling, guaranteeing the monitoring effect of the soil.

[0020] This invention uses a linkage plate to move the retaining arc member on the slide to fit together with the sampling tube. Each linkage plate is equipped with two retaining arc members, one half of which is fixedly connected to the extension rod, and the other half is fixedly connected to the linkage plate. When the sampling tube is vertically inserted into the extension rod, the retaining arc member fixed on the extension rod above the corresponding position will fit and connect with one side of the sampling tube, and the retaining arc member on the other side will be moved down by the linkage plate to fit and connect with the other side of the sampling tube. This can stably restrict the sampling tube to the extension rod for use, ensuring that the soil can be sampled stably. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0029] Please see Figures 1-3 ,and Figure 7 , This invention provides an in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments. An in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments includes a drilling device 1, a mounting plate 2, a controller 3, a display screen 4, a handle 5, and telescopic rods 6. The drilling device 1 is inserted into the middle of the lower end of the mounting plate 2, and two telescopic rods 6 are inserted into both sides of the lower end of the mounting plate 2. The two telescopic rods 6 are symmetrically arranged on the left and right sides of the drilling device 1 through the mounting plate 2. The upper end of the mounting plate 2 is equipped with a controller 3 and a display screen 4, and the controller 3 and the display screen 4 are electrically connected.

[0030] The drilling device 1 is provided with a sampling component 11, a docking rod 12, a clamping connector 13, and a connecting rod 14. The sampling component 11 is fitted to the lower end of the connecting rod 14, and the end of the connecting rod 14 away from the sampling component 11 is inserted into the lower end of the docking rod 12. The top of the docking rod 12 is fixedly connected to the clamping connector 13, and the clamping connector 13, the docking rod 12, and the connecting rod 14 are sequentially connected and arranged on the same straight line.

[0031] The sampling component 11 includes a drill bit 111, a rotating component 112, a support rod 113, a collection component 114, and a rotating drum 115. The drill bit 111 is installed at the lower middle position of the rotating component 112, and the middle position of the rotating component 112 is fitted with the rotating drum 115. The end of the rotating drum 115 away from the rotating component 112 is fixedly connected to the support rod 113. The top of the support rod 113 is vertically inserted into the bottom middle position of the collection component 114.

[0032] The drilling device 1 and four telescopic rods 6 are installed parallel to each other at the bottom of the mounting plate 2. The operator moves the mounting plate 2 to the corresponding position using the handle 5, and places the sampling component 11 on the drilling device 1 against the position. The telescopic rods 6 on both sides then provide support and leveling, allowing the sampling component 11 to be vertically and stably placed into the corresponding position. The clamping connector 13, the connecting rod 12, and the connecting rod 14 are connected in sequence to assist the sampling component 11 in inserting into the soil. The drill bit 111 on the sampling component 11 and the rotating component 112 cooperate to rotate and insert into the soil. Then, the collection component 114 moves to collect and sample the soil.

[0033] The telescopic rod 6 is installed on the four sides of the mounting plate 2. The telescopic rod 6 has a certain telescopic function and can be adjusted up and down in conjunction with one end of the drilling device 1, so that the drilling device 1 can move down stably to take samples.

[0034] The top of the connector 13 is fixedly inserted into the middle position of the bottom of the mounting plate 2, so that the connecting rod 12 and the connecting rod 14 cooperate to vertically install the sampling component 11 in the corresponding position, and the soil is sampled and collected through the sampling component 11.

[0035] The top of the collecting component 114 is connected to the connecting rod 14, so that the drill bit 111 is perpendicular to the soil. The drill bit 111 is mounted on the rotating component 112, and the rotating component 112 is rotated and adjusted under the action of the rotating drum 115, and then drills into the soil.

[0036] The rotating assembly 112 includes a rotating shaft 1121, a housing 1122, a rotating adjustment component 1123, spiral blades 1124, and insert rods 1125. There are six rotating shafts 1121, and insert rods 1125 are inserted into each of the six rotating shafts 1121. The six insert rods 1125 are equidistantly arranged in a ring on the housing 1122 and are slidably connected. Multiple spiral blades 1124 are installed on the outside of the housing 1122 at equal intervals. The housing 1122 is engaged with the rotating adjustment component 1123 at the middle position, and the housing 1122 rotates through the rotating adjustment component 1123.

[0037] Multiple curved spiral blades 1124 are equidistantly arranged in a ring on the outside of the housing 1122. The housing 1122 rotates clockwise under the action of the rotating adjustment component 1123. The multiple spiral blades 1124 rotate under the drive of the housing 1122 to loosen and separate the soil, which helps the collection component 114 to move down to collect the soil.

[0038] The working principle of the above technical solution is explained below: In use, the drilling device 1 and four telescopic rods 6 are installed parallel to each other at the bottom of the mounting plate 2. The operator moves the mounting plate 2 to the corresponding position using the handle 5. The four telescopic rods 6 are installed on the four sides of the mounting plate 2. The telescopic rods 6 have a certain telescopic function, allowing for vertical adjustment of one end of the drilling device 1, enabling the drilling device 1 to move stably downwards for sampling. Then, the controller 3 and the display screen 4 work together to simultaneously control the drilling device 1 and the four telescopic rods 6. During the downward movement of the drilling device 1, the telescopic rods 6 simultaneously retract inwards, pressing the sampling component 11 on the drilling device 1 against the position of use. The top of the snap-fit ​​connector 13 is fixedly inserted into the middle of the bottom of the mounting plate 2, allowing the connecting rod 12 and the connecting rod 14 to vertically install the sampling component 11 in the corresponding position. The telescopic rods 6 on both sides provide support and leveling, allowing the sampling component 11 to be vertically and stably placed in the corresponding position. The snap-fit ​​connector 13, connecting rod 12, and connecting rod 14 are connected in sequence to constrain the sampling component 11 to the same straight line, thereby assisting the sampling component 11 to be vertically inserted into the soil. The sampling component 11 is used to collect soil samples. The top of the collection component 114 is connected to the connecting rod 14, so that the drill bit 111 is perpendicular to the soil. The drill bit 111 is installed... The rotating assembly 112, under the action of the rotating drum 115, rotates and adjusts to drill into the soil. During the rotation of the rotating assembly 112, the rotating adjustment component 1123 at its middle position is fixedly connected to the drill bit 111, and the upper end of the rotating adjustment component 1123 is engaged with the rotating drum 115 for rotational adjustment. This allows the rotating adjustment component 1123 to drive the drill bit 111 to rotate and drill the soil under the action of the rotating drum 115. At the same time, the housing 1122 is also driven. Multiple curved spiral blades 1124 are equidistantly arranged in a ring on the outside of the housing 1122. The housing 1122 is driven by the rotating adjustment component 1123. Under the action of the mechanism, the spiral blades 1124 rotate clockwise and rotate under the drive of the housing 1122 to loosen and separate the soil. After the housing 1122 rotates to a certain position, the rotating shaft 1121 drives the insertion rod 1125 to slide smoothly outside the rotating adjustment part 1123, thereby sliding outward from the housing 1122 and inserting into the soil. This effectively assists in limiting the housing 1122, helps the collection component 114 to move down to collect the soil, and effectively assists the drill bit 111 to drill the soil, avoiding the shaking phenomenon of the drill bit 111 during the drilling process. This allows for stable collection and sampling, ensuring the monitoring effect of the soil. Example

[0039] Please see Figures 4-6 , This invention provides an in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments. The collection assembly 114 includes a linkage plate 1141, an extension rod 1142, a retaining ring 1143, a sampling tube 1144, a retaining arc member 1145, and a slide rail 1146. There are four linkage plates 1141, and all four linkage plates 1141 are slidably connected on the slide rail 1146. The four slide rails 1146 are set on four corresponding extension rods 1142, and a sampling tube 1144 is inserted into each of the four extension rods 1142. The sampling tube 1144 is engaged with the retaining arc member 1145, and half of the retaining arc member 1145 is fixedly connected to the extension rod 1142, while the other half is fixedly connected to the linkage plate 1141. The four extension rods 1142 are equidistantly and annularly inserted into the retaining ring 1143.

[0040] The retaining ring 1143 is fixedly connected to the top of the support rod 113. The retaining ring 1145 is driven by the linkage plate 1141 to move on the slide rail 1146 to fit against the sampling tube 1144, thereby stably restricting the sampling tube 1144 on the extension rod 1142 for use.

[0041] The sampling tube 1144 is provided with a collection chamber 1441, a tube body 1442, and an opening and closing assembly 1443. The collection chamber 1441 is located in the middle of the tube body 1442, and the opening and closing assembly 1443 is installed at the lower end of the tube body 1442. The opening and closing assembly 1443 is located at the lower end of the tube body 1442 and is movably connected.

[0042] The cylinder 1442 is inserted through the end of the extension rod 1142. The position of the cylinder 1442 is limited by locking the extension rod 1142 with the arc-locking member 1145, so that the cylinder 1442 is not easy to shift or slip out during the sampling process.

[0043] The opening and closing assembly 1443 includes a sliding head 4431, a chuck 4432, an inlet 4433, an adjusting rod 4434, and a closing baffle 4435. There are five sliding heads 4431, which are located on four adjusting rods 4434. The five adjusting rods 4434 are equidistantly arranged in a ring on the chuck 4432, and the inlet 4433 is located in the middle of the chuck 4432. Five closing baffles 4435 are provided on the inlet 4433, and the five closing baffles 4435 are slidably connected by the sliding heads 4431 to form a circular structure on the inlet 4433.

[0044] The sliding head 4431 drives the closing baffle 4435 to slide on the adjusting rod 4434, so that the five closing baffles 4435 slide outward through the sliding head 4431, so that the inlet 4433 is directly exposed, which helps the cylinder 1442 to sample the soil. After the cylinder 1442 has finished sampling, the closing baffles 4435 slide inward through the sliding head 4431, so that the inlet 4433 closes and opens accordingly, effectively blocking the soil collected inside the cylinder 1442.

[0045] The working principle of the above technical solution is explained below: In use, the retaining ring 1143 on the collecting assembly 114 is fixedly connected to the top of the support rod 113 and the bottom of the connecting rod 14. Four extension rods 1142 are connected to the retaining ring 1143. Each of the four extension rods 1142 is equipped with a linkage plate 1141. The linkage plate 1141 drives the retaining arc member 1145 to move on the slide rail 1146 to fit against the sampling cylinder 1144. Each linkage plate 1141 has two retaining arc members 1145, half of which is fixedly connected to the extension rod 114. 2. The other half is fixedly connected to the linkage plate 1141. The sampling tube 1144 is vertically inserted into the extension rod 1142. Above the corresponding position, the retaining arc piece 1145 fixed on the extension rod 1142 will fit and connect with one side of the sampling tube 1144. The retaining arc piece 1145 on the other side will be driven down by the linkage plate 1141 and fit and connect with the other side of the sampling tube 1144. This can stably restrict the sampling tube 1144 to the extension rod 1142 for use. The tube body 1442 is inserted through the end of the extension rod 1142, and the retaining arc piece... 1145 engages with extension rod 1142 to limit the position of cylinder 1442, preventing cylinder 1442 from shifting or slipping out during sampling. When cylinder 1442 moves downwards to sample the soil, the opening / closing assembly 1443 can be adjusted accordingly. The sliding head 4431 on the opening / closing assembly 1443 drives the closing baffles 4435 to slide on the adjusting rod 4434, causing the five closing baffles 4435 to slide outwards via the sliding head 4431, directly exposing the inlet 4433, which helps the cylinder 1442 to... Soil sampling is performed. Conversely, after sampling is completed, the closed baffle 4435 slides inward through the sliding head 4431, causing the inlet 4433 to close and open accordingly. This effectively blocks the soil collected inside the cylinder 1442, preventing soil from falling out during the collection process and ensuring stable soil sampling. Furthermore, under the action of the linkage plate 1141, the four cylinders 1442 can simultaneously collect and monitor soil from four angles, thereby improving soil sampling efficiency.

The retaining ring (1145) is driven by the linkage plate (1141) to move on the slide (1146) to fit against the sampling tube (1144), thereby stably restricting the sampling tube (1144) on the extension rod (1142) for use.

6. An in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments according to claim 5, characterized in that: The sampling tube (1144) is provided with a collection chamber (1441), a tube body (1442), and an opening and closing assembly (1443). The collection chamber (1441) is located in the middle of the tube body (1442), and the opening and closing assembly (1443) is installed at the lower end of the tube body (1442). The opening and closing assembly (1443) is located at the lower end of the tube body (1442) and is movably connected. The cylinder (1442) is inserted through the end of the extension rod (1142). The position of the cylinder (1442) is limited by locking the extension rod (1142) with the arc-locking component (1145), so that the cylinder (1442) is not easy to shift or slip out during the sampling process.

7. An in-situ soil environmental monitoring device for evaluating the efficacy of microbial amendments according to claim 6, characterized in that: The opening and closing assembly (1443) is provided with a sliding head (4431), a chuck (4432), an inlet (4433), an adjusting rod (4434), and a closing baffle (4435). There are five sliding heads (4431), and the five sliding heads are set on four adjusting rods (4434). The five adjusting rods (4434) are equidistantly arranged in a ring on the chuck (4432), and the inlet (4433) is provided in the middle of the chuck (4432). The inlet (4433) is provided with five closing baffles (4435), and the five closing baffles (4435) are slidably connected by the sliding heads (4431) to form a circular structure on the inlet (4433). The sliding head (4431) drives the closed baffle (4435) to slide on the adjusting rod (4434), so that the five closed baffles (4435) slide outward through the sliding head (4431), so that the inlet (4433) is directly exposed, which helps the cylinder (1442) to sample the soil. After the cylinder (1442) has finished sampling, the closed baffle (4435) slides inward through the sliding head (4431), so that the inlet (4433) closes and opens accordingly, effectively blocking the soil collected inside the cylinder (1442).

8.
