Description

Technical Field

[0001] The present invention relates to the technical field of soil fertilizer detection, and more specifically to a detection device for soil fertilizers. Background Art

[0002] Before planting crops, it is necessary to take samples of the soil in the determined fields for detection, so that the fertilizers and other elements contained in the current soil can be detected by the detection device. Thus, after planting, reasonable fertilization can be carried out mainly targeting the nutrients lacking in the soil, thereby improving the yield and quality of the crops. Therefore, the planting intensity of the crops can be indirectly improved through the detection device; In summary, the inventor found that the existing detection devices mainly have the following defects: Since the current detection devices usually transport the soil samples to relevant detection areas for placement and detection, there will be inconvenience during detection and it is impossible to perform real-time detection in the fields. Thus, during the transportation process, the water molecules of the soil samples will volatilize due to the influence of the spatial environment factors, and some microorganisms will be damaged due to the environmental changes. Therefore, the accuracy of soil fertilizer detection will be reduced. Summary of the Invention

Based on the new detector at the lower end of the intelligent host, the circuit board fixing groove and the independent power supply are positioned through insulators, and then the intelligent host is vertically installed and electrically connected. Subsequently, the inserted contact detector at the bottom uses the connecting sleeve at the bottom plate of the data transmission board to vertically fix and electrically connect with the sensor inside the sensor storage box. After splicing, it is directly inserted into the field to make full contact with the soil. At the same time, the sensor detects the components of the soil such as salt, humidity, pH value, and fertilizer, and finally feeds back to the display control panel. Therefore, it improves the detection accuracy and efficiency of the detection device for soil fertilizer, replacing the original situation where sampling and transportation are required for detection, resulting in a longer cycle.

[0019] 2. After further improvement of the lower layer of the bottom plate, based on the superimposed pressure plate, the perpendicularity of the connecting sleeve can be improved according to the three groups of limiting rings carried on the surface. Furthermore, the positioning blocks at the edge position the vibration module in parallel. So that after the sensor is inserted into the soil, the vibration module drives the loose soil to vibrate. At the same time, the double-axis driver of the edge pusher uses the drive shaft to drive the vertical block to slide down, and the pressure plate presses the soil, which can further improve the sufficient contact between the sensor and the soil, avoiding the loosening of the soil at the stress position after insertion, and thus can further improve the detection accuracy of soil fertilizer.

[0020] 3. After further improvement of the portable connection cover, the two limiting protection blocks at the lower end of the solid plate can be inserted into the edge of the loading groove of the intelligent host. Then, the bottom adsorption block fits against the inner bottom layer of the host to ensure the vertical accuracy when the lengthening bolt is locked. Finally, it is carried by the handle rod. Therefore, the detection device can achieve the effect of being easy to carry. At the same time, the four connecting blocks arranged inside the limiting protection blocks can penetrate and lock the corners of the sponge pad, so that the cooperation of the sponge pad can avoid scratching the edge of the display control panel and the sensor storage box after insertion, thereby improving the protection of the components.

During detection, the pressing plate 1655 provided at the lower layer of the bottom plate 165 can improve the connection verticality of the connection sleeve 164 through the three groups of limit rings 1653 carried on the surface. Then, the vibration module 1651 is horizontally positioned according to the positioning block 1652 at the edge, so that the vibration module 1651 can drive the soil position where the sensor is inserted to vibrate, ensuring that the edge soil can flow back to the lower position.
