Technical Field

[0001] The present invention relates to the technical field, and in particular to a soil quality monitoring device for uncultivated wasteland and a use method thereof. Background Art

[0002] Wasteland refers to all land that can be developed and constructed but has not yet been developed and constructed, mainly including wasteland suitable for agriculture, forestry and animal husbandry, etc. It also refers to land suitable for cultivation but has not yet been cultivated and land that has been cultivated but has been abandoned and stopped cultivation for a short time. The former is virgin wasteland and the latter is cultivated wasteland. Both are important reserve land resources in agricultural land. Some wasteland does not meet the cultivation requirements before cultivation. It is necessary to maintain the wasteland so that the nutrient content of the soil meets the standards before cultivation. Therefore, it is necessary to monitor the quality of the soil regularly.

The crushed soil passes through the filter (503) and enters the sample cup (404) under the action of the material collecting cover (405); Step 3: After the soil enters the sample cup (404), the second electric push rod (401) extends to send the sample cup (404) into the detection slot of the detector (305) to detect the soil. After sampling at one location, the sampling assembly (6) is slightly turned up and the second motor (201) is operated to rotate the first gear (202) along the ring gear (204) to adjust the position of the sampling assembly (6) so that the sampling assembly (6) can sample soil in different directions. Step 4: After the test is completed, the sample cup (404) moves upward, and the baffle (304) is inserted into the material tube (302) under the push of the No. 1 electric push rod (306), blocking the lower end of the material tube (302). Then the No. 3 motor (402) is operated to drive the sample cup (404) to flip over, pouring out the soil inside it, so that the soil is discharged from the material tube (302) through the groove (303). Then the solenoid valve (507) is opened. At this time, the material tube (302) is in a tilted state, so that the soil above the filter (503) is discharged from the material tube (302) for the next soil test.
