Embodiment 1
[0037] Such as Figure 1 to Figure 8 As shown, the figure schematically shows that the field cultivating depth measuring device includes a support component 1 , a rotating shaft assembly 2 , a rotating shaft mounting plate 21 , a connecting plate 3 and an angle sensing element 4 .
[0038] In the embodiment of the present application, the lower end of the support member 1 is in direct contact with the surface of the cultivated land.
[0039] It should be noted that the field cultivating depth measuring device of the present application is installed on the cultivator, and is separated from the cultivating shovel on the cultivator by a certain horizontal distance. The surface of the cultivating land is in contact. At this time, the supporting part 1 and the cultivating shovel will produce a certain height difference in the longitudinal direction. The height difference between the supporting part 1 and the cultivating shovel measured by the angle sensing element 4 is that is the...

The invention relates to the field of agricultural engineering technology, and discloses a field intertillage depth measuring device and a measuring method thereof. The device comprises the componentsof a supporting component; a rotating shaft assembly which comprises a rotating shaft mounting board, a bearing rotating shaft arranged at the upper end of the rotating shaft mounting board, and a supporting rotating shaft which is arranged at the lower end of the rotating shaft, wherein the upper end of the supporting component is arranged at the lower end of the rotating shaft mounting board through the supporting rotating shaft; a connecting board which is provided with a bearing assembly that sleeves the bearing rotating shaft; and an angle sensing component which comprises a sensing board arranged on the connecting board, and a magnet which is arranged in the sensing body. Through rotation of the supporting component, the rotating shaft mounting board is driven to perform synchronousrotation. Through rotation of the rotating shaft mounting board, rotation of the bearing rotating shaft is driven. Through rotation of the bearing rotating shaft, the magnet is driven to perform magnetic line cutting relative to the sensing body, thereby obtaining the rotation angle of the supporting component. The field intertillage depth measuring device has advantages of high measurement accuracy, direct and simple operation, and high convenience.
Description
technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to a field intertillage depth measuring device and a measuring method thereof. Background technique [0002] At present, most of the measurement of intertillage depth in my country still adopts the method of manual measurement, that is, the soil layer that has been operated by the tool is scraped to expose the bottom of the operation soil layer, and then the steel ruler is used for measurement. This method is not only labor-intensive, but also relies on The method of determining the bottom of the ditch by digging up the soil layer after the operation of the machine is highly subjective, and the measurement is not accurate enough, and only small-capacity samples can be sampled and measured. [0003] Ultrasonic sensors are currently used to measure cultivating depth, but this technology is easily affected by uneven ground, crop leaves, and stubble, which is difficult t...
