Description

Technical Field

[0001] This invention relates to the field of soil testing technology, specifically to a soil testing system and testing method. Background Technology

[0002] With societal development, the chemical industry has advanced, and land is frequently subjected to various forms of pollution, including chemical fertilizers and metallic waste. The degree of pollution is such that soil itself struggles to self-purify, and this contaminated soil, washed into rivers by rainwater, easily leads to eutrophication. Therefore, soil testing is urgently needed. Technicians can develop different remedial plans to improve soil pollution based on the results of testing. Existing soil testing equipment uses simple sampling tools to collect samples, followed by analysis by instruments. However, most contaminated soil is corrosive, and direct contact with the soil can easily cause skin damage to testing personnel.

[0003] Existing testing devices typically use a single auger for soil sampling. This structure is relatively simple, and the amount of soil obtained cannot be guaranteed, resulting in large clumps of soil. This leads to low sampling efficiency and reduced testing accuracy. Furthermore, the inability to control the synchronization of sampling and testing in subsequent sampling and testing processes disrupts the normal operation of these processes, affecting overall testing efficiency. In view of this problem, there is a need in the market for a soil testing device that can improve soil pulverization and enable orderly sampling and testing. Summary of the Invention

[0013] This invention also proposes a soil testing method, as follows:

[0014] S1: Move the device to the location where it needs to be tested, turn on the control switch of the first rotating motor, the first rotating motor drives the lead screw to rotate through the first belt, and the lead screw drives the protective shell to move downward;

[0015] S2: Turn on the control switches of the second and third rotating motors. The second rotating motor controls the rotation of the second roller through the connecting belt, and the third rotating motor controls the rotation of the first roller. By rotating the first and second rollers at different angles, the soil is further crushed. The crushed soil enters the protective shell through the second roller. Then, the first rotating motor is controlled to rotate in the opposite direction. The protective shell moves upward through the lead screw, and the soil is poured into the surface of the first incomplete gear through the outlet of the protective shell.

[0016] S3: The first rotating motor controls the drive rod to rotate via the second belt. The drive rod drives the first incomplete gear to rotate. The soil on the first incomplete gear falls into the collection box below through the second discharge port under the action of the push plate. The connecting shaft is intermittently rotated under the action of the lever on the mating shaft. When the detection block squeezes the collection box, the detector detects the soil.

[0017] S4: As the protective shell descends, the L-shaped rod controls the piston rod to move downwards. The piston rod moves inside the cylinder, and the water-blocking plate rotates downwards around the rotating rod. Water flows into the cylinder through the outlet. When the protective shell rises, the piston rod moves upwards, and the cylinder compresses the air inside. The air pressure forces the water out, and the water-blocking plate blocks the outlet under pressure. Water is then sprayed out from the end of the spray pipe, spraying the rising rotating roller.

[0018] Preferably, when the notch of the first incomplete gear in step 3 rotates to the notch of the second incomplete gear, the second incomplete gear stops rotating, and the lever continues to drive the rotation of the second incomplete gear through the mating shaft.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention uses a crushing and collecting component to crush and sample soil. The rotation of the first and second rotating rollers is achieved by the rotation of the second and third rotating motors, which improves the crushing effect of the soil and prevents the formation of large clumps of soil.

[0021] 2. This invention uses a detection component to further collect and test the sampled soil. The rotation of the drive rod is controlled by a second belt, and the intermittent rotation of the second incomplete gear is controlled by a lever and a mating shaft, thereby achieving orderly detection of the soil and effectively improving the accuracy of the detection.

[0022] 3. The present invention cleans the crushing and collecting component by spraying the component. When the crushing and collecting component rises, the piston rod is controlled by the L-shaped rod to move in the cylinder. The air pressure in the cylinder sprays the water in the water tank onto the first rotating roller, thereby cleaning the first rotating roller and preventing the mud clumps on the rotating roller from affecting the sampling effect.

[0047] A soil testing method comprising the following steps:

[0048] S1: Move the device to the location where it needs to be tested, turn on the control switch of the first rotating motor 107, the first rotating motor 107 drives the lead screw 111 to rotate through the first belt 103, and the lead screw 111 drives the protective shell 114 to move downward.

[0049] S2: Turn on the control switches of the second rotating motor 118 and the third rotating motor 120. The second rotating motor 118 controls the rotation of the second rotating roller 122 through the connecting belt 116, and the third rotating motor 120 controls the rotation of the first rotating roller 113. The soil is further crushed by rotating the first rotating roller 113 and the second rotating roller 122 at different angles. The crushed soil enters the protective shell 114 through the second rotating roller 122. Then, the first rotating motor 107 is controlled to rotate in the opposite direction. The protective shell 114 moves upward through the lead screw 111, and the soil is poured into the surface of the first incomplete gear 203 through the outlet of the protective shell 114.

[0050] S3: The first rotating motor 107 controls the drive rod 201 to rotate through the second belt 222. The drive rod 201 drives the first incomplete gear 203 to rotate. The soil on the first incomplete gear 203 falls into the collection box 223 below through the second discharge port 220 under the action of the push plate 202. The connecting shaft 226 is intermittently rotated under the action of the lever 213 on the mating shaft 217. When the detection block 210 squeezes the collection box 223, the detector 228 detects the soil.

[0051] S4: As the protective shell 114 descends, the L-shaped rod 303 controls the piston rod 306 to move downward. The piston rod 306 moves inside the cylinder 307, and the water-blocking plate 308 rotates downward around the rotating rod 305. Water flows into the cylinder 307 through the outlet. When the protective shell 114 rises, the piston rod 306 moves upward, and the cylinder 307 compresses the air inside. The air pressure forces the water out. The water-blocking plate 308 blocks the outlet after being pressurized, and the water flows out from the port of the spray pipe 302 to spray the rising rotating roller.

[0052] When the notch of the first incomplete gear 203 in step 3 rotates to the notch of the second incomplete gear 218, the second incomplete gear 218 stops rotating, and the lever 213 continues to drive the rotation of the second incomplete gear 218 through the mating shaft 217.

[0053] Working principle: Move the device to the location where it needs to be tested, fix the device with fixing block 4, turn on the control switch of the first rotating motor 107, the output end of the first rotating motor 107 drives the first rotating wheel 104 to rotate, the first rotating wheel 104 drives the second rotating wheel 102 to rotate through the first belt 103, the second rotating wheel 102 drives the lead screw 111 to rotate, and the lead screw 111 drives the protective shell 114 connected to it to move downward.

[0054] When the protective shell 114 moves downward, the first telescopic rod 119 and the second telescopic rod 121 control the movement of the second rotating motor 118 and the third rotating motor 120 respectively. The control switches of the second rotating motor 118 and the third rotating motor 120 are turned on. The output end of the second rotating motor 118 drives the rotation of the first connecting roller 115. The first connecting roller 115 controls the rotation of the second connecting roller 124 through the connecting belt 116. The second connecting roller 124 drives the rotation of the second rotating roller 122. The third rotating motor 120 drives the rotation of the first rotating roller 113. The soil is crushed by rotating the first rotating roller 113 and the second rotating roller 122 at different angles. The crushed soil is transported to the inside of the protective shell 114 through the second rotating roller 122. The soil inside the protective shell 114 falls into the surface of the first incomplete gear 203 through the opening.

[0055] While the first rotating motor 107 is working, it drives the fourth rotating wheel 224 to rotate. The fourth rotating wheel 224 drives the third rotating wheel 221 to rotate via the second belt 222. The third rotating wheel 221 controls the drive rod 201 to rotate, which in turn controls the first incomplete gear 203 to rotate. The soil on top also rotates accordingly. The push plate 202 controls the soil to accumulate. When the first discharge port 219 and the second discharge port 220 coincide, the soil falls into the collection box 223 through the common outlet. The first incomplete gear 203 drives the second incomplete gear 218 to rotate, which in turn drives the connecting shaft 226 to rotate. The connecting shaft 226 drives the working sleeve 20 8. In operation, when the detection block 210 falls on the surface of the collection box 223, the first rack 216 moves downward under the influence of gravity, and the detector 228 detects the soil through the detection block 210. When the detection block 210 is perpendicular to the collection box 223, the first rack 216 moves upward under the action of force, completing the detection of the soil inside the collection box 223. When the notch of the first incomplete gear 203 rotates to the notch of the second incomplete gear 218, the second incomplete gear 218 stops rotating after losing the force. The second incomplete gear 218 is intermittently rotated by the action of the lever 213 on the mating shaft 217, thereby realizing the orderly detection of the soil.

[0056] When the protective shell 114 moves downward, the piston rod 306 moves inside the cylinder 307 controlled by the L-shaped rod 303. The water-blocking plate 308 rotates downward around the rotating rod 305, and the cylinder 307 absorbs water from the water tank 301. When the protective shell 114 rises, the piston rod 306 moves upward, and the water-blocking plate 308 is controlled to rotate by the fixing plate 304. The water in the cylinder 307 flows out through the water spray pipe 302, thereby cleaning the first rotating roller 113.
