Background

Soil fertilizer monitoring refers to determining soil quality, contained nutrients and variation trends thereof by measuring representative values of factors affecting soil fertility. In the process of monitoring soil fertilizer, relevant staff firstly use soil fertilizer nutrient sampling device to sample soil. Patent document No. CN213239546U discloses a soil fertilizer nutrient sampling device. The device passes through the moving mechanism on the base bottom and removes the device to appointed operation region, it is rotatory to drive the action wheel on the output shaft through starting the first motor on the mounting panel, thereby the action wheel drives the rotation of realizing first threaded rod from the driving wheel rotation through the connecting band, thereby the movable plate of installing when first threaded rod rotates follows the removal and promotes the diaphragm and remove and make the sample connection move to the sample region, thereby it takes a sample to insert the sample connection in soil to drive the second threaded rod through starting the second motor and rotate and make the loading board take place to remove. Although the device has more beneficial effects, the following problems still exist: the device drives the second threaded rod to rotate through the second motor and then drives the loading plate to move downwards so as to insert the sampling head into the soil. This load that causes the second motor is very big, can cause comparatively serious damage to the second motor, has seriously reduced the life of second motor, when taking a sample to the hard soil of tie, can directly damage the second motor even. This can greatly increase the cost of soil fertilizer monitoring, reduces the efficiency of soil fertilizer monitoring. In view of this, we propose a soil fertilizer nutrient sampling device.
