Description

Technical Field

[0001] The invention relates to the technical field of deep soil physical detection, and in particular to a soil detection device used for measuring deep soil components. Background Art

[0002] Soil is the basis of agricultural production and one of the important resources for human survival. However, with the increase in population and industrialization, a large amount of soil pollution has occurred. In order to rationally plan and use the land, agricultural planting, detect soil pollution and protect the environment, it is necessary to test the soil. In order to better detect, deep soil testing is usually carried out. Traditional deep soil testing equipment usually uses a motor to drive the drill bit to drill downwards, and after reaching the appropriate position, the soil is tested by a soil testing rod. A Chinese patent discloses a soil detection device for deep soil detection (authorization announcement number CN117517622B). The patent technology discloses a soil detection device for deep soil detection, including: a support trolley, a fixing mechanism, a soil collection mechanism, a soil detection mechanism and a cleaning mechanism. A support top plate is fixedly installed on the support trolley, and the support top plate is provided with multiple fixing mechanisms arranged on the top of the support top plate, so that the support trolley is fixed on the soil, the soil collection mechanism is arranged on the support top plate, and is used to collect and detect the soil. The soil detection mechanism is arranged on the support top plate, and is used to detect deep soil. The cleaning mechanism is arranged on the support top plate, and is used to clean the soil collection mechanism. Through the above technical scheme, the problem that most soil detection equipment in the prior art cannot detect and collect soil at the same time, resulting in the inability to accurately obtain soil detection data, is solved. This patented technology solves the problem that most of the deep soil detection equipment in the prior art drills the probe into the soil and then uses the soil detection probe to perform a one-time detection of the soil, which may result in inaccurate detection. It is necessary to collect the soil and then test the data multiple times before the final soil detection result can be determined. Most of the soil detection equipment in the prior art cannot detect and collect soil at the same time, resulting in the inability to accurately obtain soil detection data.

[0003] However, in the prior art, different soil compositions require different depths for deep soil sampling, ranging from 0 to 5 m for shallow soil to 5 to 15 m for deep soil. It is necessary to solve the problem that the prior art is conducive to sampling and testing soil at different depths, and that the depth of the sampling soil can be adjusted according to the different compositions of the soil depth.

[0004] Therefore, those skilled in the art provide a soil testing device for measuring deep soil components to solve the problems raised in the above background technology. Summary of the invention

[0037] Technical effects and advantages of the present invention:

[0038] In the deep drilling and sampling preparation of the present invention, the deep soil drilling component works, the servo motor three is started, and the spur gear is driven to rotate, and then the drilling bit is driven to rotate into the ground through the outer gear ring. As the drilling bit rotates, the servo motor one is started to rotate the vertical screw, and the lifting frame box drives the deep soil detection structure, the soil depth extension component and the deep soil drilling component to descend, and the drilling bit continues to drill holes along the adjustment hole, so that the deep soil drilling component and the soil depth extension component penetrate into the ground. The deep sampling has strong applicability.

The servo motor, the drilling motor and other multiple motors work together to realize the automation of a series of operations such as drilling, sampling and transmission, reduce manpower input, improve work efficiency, and the sampling process is continuous. When sampling soil, the deep soil drilling component and the soil depth extension component perform soil transmission in a continuously descending state, thereby ensuring continuous sampling of soils at different depths and obtaining more comprehensive and accurate soil samples.

[0040] In the present invention, soil sampling is performed by starting the second servo motor to drive the active rod to rotate, and the driven rod 1 in the soil depth extension component is rotated through the transmission square rod. The driven rod 1 is connected with the driven rod 2 in the deep soil drilling component through the docking square rod, so that the active rod, the driven rod 1 and the driven rod 2 are rotated at the same time. The rotating active rod, the driven rod 1 and the driven rod 2 drive the sampling spiral 1, the sampling spiral 2 and the sampling spiral 3 to rotate at the same time, so as to transfer the soil to the discharge trough.

[0041] Soil transmission and detection: the soil in the discharge trough is transmitted through the conveying pipe, and the brushless motor is started to drive the conveying auger to rotate, and the soil is transmitted to the soil detection machine for automatic soil identification, moisture, temperature, salinity, pH and other multi-parameter detection. Multi-parameter detection can automatically identify the soil and simultaneously detect multiple parameters such as soil moisture, temperature, salinity and pH, providing rich data support for soil analysis.

[0132] According to the above embodiments, the working principle of the present invention is:

[0133] Before soil sampling, the deep soil detection mobile frame 1 is moved to the ground where sampling is required, and then the deep soil detection mobile frame 1 can be positioned on the ground through four soil detection positioning structures 4, and the servo motor four 405 is started. After the servo motor four 405 is started, it drives the screw rod 404 to rotate, so that the screw rod 404 spirally transmits the screw plate frame 406, so that the screw plate frame 406 drives the drilling cone rod 408 at the bottom of the servo drilling motor 407 to descend, until it is started, and the servo motor four 405 and the drilling motor 407 rotate at the same time, the rotation of the drilling motor 407 drives the drilling cone rod 408 to rotate on the ground, and descend into the ground, and the deep soil detection mobile frame 1 is positioned on the ground through the drilling cone rod 408;

[0134] The soil depth extension component 22 and the deep soil drilling component 23 in the deep soil sampling structure 2 are both modularly configured, and multiple soil depth extension components 22 can be assembled with each other to increase the applicability of deep soil sampling;

[0135] The deep soil drilling assembly 23 starts the servo motor 3 2312, and after the servo motor 3 2312 is started, it drives the spur gear 2311 to rotate, and the spur gear 2311 engages with the outer gear ring 2310, and the rotating outer gear ring 2310 drives the drilling bit 2302 fixed at the bottom of the limit plate 2307 to rotate, and the rotating drilling bit 2302 rotates into the ground;

[0136] When the earth-boring drill bit 2302 rotates, the servo motor 204 is started, and the servo motor 204 drives the vertical screw 203 to rotate, so that the lifting frame box 201 passes through the screw adjustment block 202 and diffracts the vertical screw 203 inside the vertical slot 5 to move downward, so that the lifting frame box 201 can simultaneously descend the soil depth extension component 22 and the deep soil earth-boring component 23 assembled at the bottom of the deep soil detection structure 21, and the descending earth-boring drill bit 2302 descends along the adjustment hole 10, and continuously rotates to open a hole in the ground, so that the deep soil earth-boring component 23 and the soil depth extension component 22 penetrate into the ground;

[0137] When the length of the soil depth extension component 22 is extended, one soil depth extension component 22 is disassembled from the deep soil detection structure 21. During disassembly, the assembly bolt 206 is removed from the docking groove 1 2203 and the docking groove 2 2304 by an external tool, and the servo motor 1 204 is reset and rotated to make the deep soil detection structure 21 rise and reset, and the docking plate 2 2209 at the bottom end of the other soil depth extension component 22 is inserted into the docking groove 1 2203 of the soil depth extension component 22, and after being locked and assembled with the assembly bolt 206, the docking plate 1 2102 of the deep soil detection structure 21 is driven by the servo motor 1 204 to descend to the docking groove 1 2203 of the other soil depth extension component 22, and after being locked and assembled with the assembly bolt 206, the deep soil sampling can be completed in an adjustable manner;

[0138] The soil depth extension components 22 are electrically connected to each other via the docking wire three 2211, and the soil depth extension components 22 and the deep soil drilling components 23 are electrically connected via the docking wire three 2211 and the docking wire four 2315, and the soil depth extension components 22 and the deep soil detection structure 21 are electrically connected via the docking wire three 2211 and the docking wire two 2117;

[0139] When sampling soil at a certain depth, the servo motor 2107 is started, and the servo motor 2107 drives the active rod 2104 to rotate, so that the active rod 2104 drives the driven rod 1 2206 in the soil depth extension assembly 22 to rotate through the transmission square rod 2105, and the driven rod 1 2206 and the driven rod 2 2314 are connected through the docking square rod 2210. When the active rod 2104 rotates, it can drive the driven rod 1 2206 and the driven rod 2 2314 to rotate at the same time;

[0140] The rotating active rod 2104, driven rod 1 2206, driven rod 2 2314 can simultaneously rotate the sampling spiral 1 2106, sampling spiral 2 2208, and sampling spiral 3 2306 to transfer the soil to the discharge trough 2108;

[0141] During the soil sampling step, the deep soil drilling assembly 23 and the soil depth extension assembly 22 are in a continuous descending state to carry out soil transmission for sampling;

[0142] The soil in the discharge trough 2108 is transferred to the conveying pipe 2115 connected to the sampling ring 2114, and the brushless motor 2120 is started. After the brushless motor 2120 is started, the conveying auger 2119 is driven to rotate inside the conveying pipe 2115, and the sampled soil inside the conveying pipe 2115 can be transferred to the soil detection machine 2124 connected to the telescopic tube 2123, so as to automatically identify the soil and synchronously detect multiple parameters of the soil, such as moisture, temperature, salinity and pH.

[0143] After the deep soil detection, the cylinder 2111 can be started to move the flushing ring 2110 in the adjustment frame 2109 to the position of the discharge trough 2108, and the high-pressure water pump 2121 can be started. The high-pressure water pump 2121 will discharge the water source in the water tank 2122 into the water supply ring 2112 through the water supply pipe 2113, and discharge the water source through the discharge trough 2108 into the sampling hole 1 2202 and the sampling hole 2 2303 connected to the bottom of the sampling inner tube 2103, so as to perform high-pressure flushing and cleaning of the sampled residual soil.
