Description

Technical Field

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

[0002] Currently, when testing soil for nut planting, in order to ensure that the soil meets the conditions for nut planting, it is necessary to ensure the comprehensiveness and accuracy of the test. Therefore, it is usually necessary to test the moisture, pH value and nutrients of the soil. Among them, soil nutrients are tested by colorimetry, and the soil samples need to be dried and crushed before testing; moisture testing requires testing the original soil samples to avoid errors; pH value requires preparing a solution of the sample, and then measuring the pH value of the solution, thereby obtaining three test indicators to determine whether the soil is suitable for nut planting.

[0003] In the aforementioned prior art, the soil samples required for moisture, pH, and nutrient testing are all in different forms. Therefore, before testing, workers need to collect three initial soil samples and pre-treat them separately before placing them in the testing device for use. In addition, the placement, treatment, and removal of the soil samples all need to be repeated three times by the workers. It is impossible to complete the testing of the three indicators of moisture, pH, and nutrients with only one sample, which increases the work pressure and labor intensity of the workers and is not conducive to improving the efficiency of soil testing.

[0042] Among them, the moisture detection sensor 2, the pH sensor 3 and the nutrient detector 4 are arranged in sequence above the detection frame 1, the outer rotating disk 5 is rotatably connected to the detection frame 1 and is sleeved on the outside of the detection frame 1, the storage tank 6 is arranged above the outer rotating disk 5, the moisture detection lifting component 7, the pH detection transfer unit and the crushing unit are arranged in sequence above the detection frame 1, the output end of the moisture detection lifting component 7 is fixedly connected to the moisture detection sensor 2, the pH sensor 3 is arranged below the pH sensor 3 transfer unit, and the nutrient detector 4 is arranged below the crushing unit. The soil sample to be tested is placed in the storage tank 6. A staff member operates the operation panel 13 to start the outer rotating disk 5 to rotate outside the detection frame 1, and the storage tank 6 moves to the bottom of the moisture detection sensor 2. The moisture detection lifting component 7 is activated, driving the moisture detection sensor 2 to be inserted into the soil sample to perform moisture content detection, and the data is displayed on the operation panel 13. The storage tank 6 continues to move to the bottom of the pH detection transfer unit, and the soil sample is removed from the storage tank 6 and transferred to the pH sensor 3 for detection. The detection data is displayed on the operation panel 13. While the pH test is being performed, the idle storage tank 6 continues to move to the pulverization unit area. The pulverization unit dries and pulverizes the soil sample in the storage tank 6, and then discharges it to obtain soil powder. The staff member extracts the soil powder with an extractant, dissolves the soil powder, and obtains a nutrient-containing solution by collecting the supernatant. A color developer is added to the nutrient-containing solution, and the nutrients react with the color developer to produce a colored substance. The nutrient content is determined by colorimetry. In addition, the model of the nutrient detector 4 is TPY-8A.

[0043] Secondly, the transverse transfer component 8 is mounted above the detection frame 1, the lifting transfer component 9 is arranged at the output end of the transverse transfer component 8, and the output end of the lifting transfer component 9 is provided with two of the carrying mechanisms; the carrying warehouse 10 and the carrying rotation drive component 11 are both rotatably connected to the output end of the lifting transfer component 9, the carrying rotation drive component 11 is located on one side of the carrying warehouse 10, and the output end of the carrying rotation drive component 11 is rotatably connected to the carrying warehouse 10, and the supporting block 12 is fixedly connected to the output end of the lifting transfer component 9, and is located on the side of the carrying rotation drive component 11 away from the carrying warehouse 10. When conducting pH testing, the storage tank 6 is first moved to the bottom of the carrying mechanism. At this time, the transverse transfer component 8 is started so that the carrying mechanism is aligned with the storage tank 6, and then the lifting and transferring component 9 is started to drive the carrying mechanism into the storage tank 6, and then the soil sample is grabbed by the carrying mechanism and transferred to the subsequent rotating cylinder 22 for pH testing; in addition, the transverse transfer component 8 is an electric slide rail, and the lifting and transferring component 9 is a self-locking cylinder; when grabbing the soil sample, the carrying rotating component is started to drive the carrying bin 10 to rotate, and then the two carrying bins 10 rotate and merge to play a carrying role, and then the grabbed soil sample is transferred to the rotating cylinder 22 for upload. At this time, the carrying bin 10 is opened, and then the outside of the carrying bin 10 can continuously contact and collide with the abutment block 12, thereby generating vibration, so that all the soil samples inside the carrying bin 10 fall down, avoiding a large amount of adhesion; wherein, the carrying rotation drive component 11 is a self-locking electric push rod.

The pH detection unit can be used to monitor the pH value of the captured soil sample. The control module is arranged inside the operation panel 13, which can be connected to various devices. By operating the operation panel 13, the various devices of the detection device can be controlled and the soil test results can be displayed to facilitate operation by the staff. The turntable drive component 14 is a self-locking motor. When adjusting the storage tank 6, the turntable drive component 14 is started, driving the gear 15 to rotate, meshing with the rack, and then driving the outer rotating disk 5 to rotate, so that the storage tank 6 is moved and adjusted accordingly.

The fixed cylinder 17 supports the stirring mechanism. When the transported soil sample enters the stirring mechanism, the pressure sensor 18 detects the weight of the soil sample. Then, the water adding mechanism injects deionized water into the rotating cylinder 22 at a ratio of 1:2.5, which is the ratio of soil weight to deionized water volume, that is, 1 gram of soil is added to 2.5 milliliters of deionized water. The stirring mechanism is then started to stir and mix. After stirring, the mixture is allowed to stand for 30 minutes to produce a supernatant in the rotating cylinder 22. At this time, the pH detection lifting component 21 is started to drive the pH sensor 3 to immerse in the supernatant to perform pH value detection. After the detection is completed, the stirring mechanism mixes the internal supernatant and soil sample again to prevent soil sedimentation and blockage during discharge. The discharge mechanism is then started for discharge. At the same time, the tilting drive component 20 can also be started to tilt the fixed cylinder 17, thereby better discharging sewage.

The rotating drum 22 and the fixed drum 17 are respectively equipped with an infrared transmitter and an infrared receiver. When sewage needs to be discharged, the infrared light from the infrared transmitter needs to be received by the infrared receiver, indicating that the valve 25 and the drain pipe 26 are aligned. Then, the valve 25 is opened, and the sewage is smoothly discharged through the drain pipe 26 and then collected in the sewage tank 27.

[0048] Furthermore, the water tank 28 is disposed outside the fixed cylinder 17, and the pump body 29 is disposed inside the water tank 28.
