Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a soil detection device and a soil detection method thereof. Background Art

[0002] By testing the content of major elements such as nitrogen, phosphorus, potassium, and trace elements such as iron, manganese, and zinc in the soil, we can understand the soil nutrient supply status, help farmers develop precise fertilization plans, avoid waste and environmental pollution caused by blind fertilization, and at the same time improve fertilizer utilization, promote crop growth, increase yield and improve quality.

[0003] Existing detection devices basically include rotatable or plug-in sampling tubes, which are screwed or inserted into the soil for sampling, and then the samples are poured out for detection. In this way, when the samples are poured out, the samples are mixed together, and the soil cannot be layered for detection and analysis. If layered detection is to be performed, multiple samplings at different depths are required, resulting in low detection efficiency.

[0004] For example, in the prior art, Publication No.: KR20190095762A, provides a soil sampling device for collecting soil samples of a cut slope, which includes: a column portion formed by interconnecting a plurality of single columns; a clamping portion formed on the front side of the column portion; and a plurality of sampling portions coupled to the rear side of the column portion and formed to be spaced apart in the longitudinal direction of the column portion. The sampling portion includes an L-structure coupling portion coupled to the column portion and a sampling box coupled to the coupling portion. The sampling box has a box-like structure with an open rear surface and an open upper surface to collect soil sampled in the sampling box, which is used to sample soil inserted into the cut slope from the side of the cut slope, and is not applicable to vertical ground sampling.

[0005] Prior art, publication number: CN116642727B, discloses a stratified sampling device for soil detection, including a supporting mechanism, a shell, a sampling mechanism, a detection mechanism, and a controller. The supporting mechanism is hinged to the shell, the sampling mechanism is tightly connected to the shell, the sampling mechanism is located inside the shell, the detection mechanism is installed on the top of the outside of the shell, the controller is tightly connected to the shell, the detection mechanism is electrically connected to the controller, a guide rail and a working room are arranged in the shell, the sampling mechanism includes an electric cylinder, a bracket, a sliding plate, a sampling tube, an exhaust fan, and an exhaust pipe. The electric cylinder is tightly connected to the shell, the electric cylinder is located in the working room, the output end of the electric cylinder is drivingly connected to the bracket, the sliding plate is tightly connected to the bracket, the sliding plate is slidably connected to the guide rail, the sliding plate is tightly connected to the sampling tube, the exhaust fan is tightly connected to the shell, the exhaust port of the exhaust fan is connected to the exhaust pipe, the sampling tube is connected to the exhaust pipe, and the sampling tube is connected to the exhaust pipe.

[0006] The main technical problem solved is the problem of device fixing. The main working principle is as follows: first, the sampling device is placed at the location where sampling is required, the stabilizer buffers the impact force, and then the fixing rod is inserted into the soil for fixing. Then the driving motor is started to drive the turntable to rotate, thereby driving the rotating sheet to cut into the soil to ensure stability. The controller analyzes the resistance between the detection rods to determine the inclination angle of the sampling device, and controls the electric push rod to extend and retract, and automatically level the sampling device. After the sampling device is fixed in place, the electric cylinder pushes the bracket to move downward, and the sliding plate is driven to move downward along the guide rail through the bracket, thereby driving the sampling tube fixed to the sliding plate to move downward and insert into the soil to a specified depth. Then the exhaust fan is started, and the air in the sampling tube is extracted through the exhaust pipe, so that the air pressure in the air guide pipe is reduced to generate negative pressure. The solenoid valve is opened, the cylinder body and the air guide pipe are connected, and the soil is sucked into the cylinder body to realize sampling, and the friction force of the soil on the friction plate drives the baffle plate to rotate, so as to realize automatic control of the suction force. After the sampling is completed, the exhaust fan is turned off, the electric cylinder pulls the sampling tube out of the soil, and the soil sucked into the cylinder body is taken out for detection.

[0007] However, the problem is that the soil sample is sucked by vacuuming to form a negative pressure. Due to the open opening, the soil sample cannot smoothly enter the sampler. After the sampling is completed, each layer of soil sample needs to be taken out separately for testing, and the calibration efficiency is also relatively low.

[0008] Therefore, it is necessary to propose a new technical solution to solve the above technical problems and improve the efficiency of soil stratification detection. Summary of the invention

[0019] By adopting the above technical solution: before sampling, the sampling blade is attached to the sampling tube under the action of the torsion shaft. When the drilling is completed, the passive component is driven by the coordination mechanism, and the passive component drives the sampling blade to unfold and expand outward. The driving motor is started again to keep the drilling depth unchanged. The sampling blade can guide the soil samples between the two rotary slices and scraped from the hole wall into the soil sample temporary storage cavity.

[0020] Optionally, the coordination mechanism includes a lifting component slidably arranged inside the sampling tube, a positioning component arranged outside the sampling tube to position the lifting component, a triggering component arranged on the lifting component and cooperating with the driven component, and a pushing component arranged on the lifting component to push the soil sample out of the soil sample temporary storage cavity.

[0026] By sampling the soil using the above method, samples at different depths of the soil can be separately sampled and temporarily stored in one sampling process. There is no need to perform multiple sampling processes at different depths. The soil can be sampled and tested in layers, which improves the efficiency of soil testing and can determine the element content at different depths of the soil layer.

[0027] The working principle and beneficial effects of the present invention are: 1. The support frame in the present invention is used to support the entire device. By setting an elastic mechanism, the power mechanism and the sampling mechanism can be moved downward as a whole under the action of pressing, which is convenient for deep sampling of the soil. By setting a layered sampling and setting out mechanism, layered sampling, temporary storage and setting out can be achieved under the adjustment of the coordination mechanism. The detection box can be used to synchronously detect the element content of soil at different depths of multi-layered soil samples, thereby improving the detection efficiency.

[0028] 2. In the present invention, the supporting legs are used to support the ground, the connecting beams ensure the stability of the entire supporting frame, the detection box is fixed on the connecting beams and is located on the side of the sampling mechanism, and does not hinder the up and down movement of the sampling mechanism.

Due to the existence of the sliding inclined surface, the trigger rod gradually pushes the driven block outward, thereby pushing the sampling blade to expand. When the lifting round rod moves up to the position of the spring block, after sliding over the inclined surface, the spring block returns to its original position and can engage the lifting round rod to form a positioning position. The sampling tube is rotated again, and the sampling blade samples the soil between the rotary slices, and the soil sample enters the soil sample temporary storage cavity for temporary storage to complete the sampling. Then, the spring block is pushed away, and the lifting round rod is pressed in the opposite direction. Under the action of the torsion shaft, the sampling blade gradually returns to its original position to close the soil sample temporary storage cavity. Then, under the action of the elastic mechanism, the sampling tube returns to its original position, and the above operation is performed again to open the sampling blade, and the square rod is pushed downward. Pushing the elastic plate can push the soil sample out of the soil sample temporary storage cavity to the detection plate for detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Before sampling, the sampling blade 620 is attached to the sampling tube 510 under the action of the torsion shaft 610. When the drilling is completed, the coordination mechanism 700 drives the driven component, and the driven component drives the sampling blade 620 to unfold and expand outward. The driving motor is started again to keep the drilling depth unchanged.
