Description

Technical Field

[0001] The utility model relates to the field of corn planting, in particular to a device for detecting the acidity and alkalinity of corn planting soil. Background Art

[0002] If the soil pH is too high, it will affect the water absorption, germination and growth of seeds. Even if the seedlings can emerge, the seedlings have a certain limit to their tolerance to the soil environment. The seedlings often grow weak and thin, leading to death. Therefore, when choosing a field to plant corn, it is necessary to test the soil pH and select a plot with moderate pH. If the pH is too high, the field can be improved before planting corn. A Chinese patent discloses an environmental soil acidity and alkalinity detection device (authorization announcement number CN219978291 U). The patented technology removes impurities on the detection needle through the friction between the detection needle and the cleaning cotton, solving the problem of time-consuming wiping and cleaning the detection needle after the device is used or using disposable items to wipe it, resulting in waste of resources. However, when performing the detection work, the staff needs to hold the main unit with one hand and insert the detection needle into the soil with the other hand for detection. When the detection needle encounters a relatively hard soil, it is difficult to insert the detection needle into the soil with one hand. At the same time, after the detection needle is used, the worker needs to pass the detection needle through the fixed box for cleaning, which is not convenient and fast enough. Therefore, those skilled in the art provide a device for detecting the acidity and alkalinity of soil for planting corn seeds to solve the problems raised in the above-mentioned background technology.

[0018] Please refer to Figures 1 to 4 , in this embodiment, a device for detecting the acidity and alkalinity of corn planting soil is provided, including a mounting plate 1. The upper end of the mounting plate 1 is inlaid with a detection host 2. Gripping rods 3 are installed at the left and right ends of the mounting plate 1. A vertical rod 4 is installed at the lower end of the mounting plate 1. A sensor 5 is installed at the lower end of the vertical rod 4. Detection needles 6 are symmetrically installed at the lower end of the sensor 5. Lifting grooves 7 are installed at the left and right ends of the vertical rod 4. A fixing rod 8 is installed inside the lifting groove 7. A lifting block 9 is slidably connected to the outer surface of the fixing rod 8. A first spring 10 is sleeved on the outer surface of the fixing rod 8, and the first spring 10 is located above the lifting block 9. A support rod 11 is installed at the lower end of the lifting block 9. Two support rods 11 are installed at the lower end of the bottom plate 12. Two through holes 13 are opened inside the bottom plate 12, and the positions of the through holes 13 correspond to those of the detection needles 6. Fixing plates 14 and moving plates 15 are symmetrically arranged above the bottom plate 12. Semi-circular grooves 16 are symmetrically opened at the inner ends of the fixing plates 14 and the moving plates 15, and the positions of the semi-circular grooves 16 correspond to those of the detection needles 6. Hidden grooves 17 are opened on the inner walls of the semi-circular grooves 16. Circular ring cleaning blocks 18 are arranged inside the two hidden grooves 17. A first round rod 19 is installed on the side surface of the fixing plate 14. A first connecting plate 20 is installed at one end of the first round rod 19, and the first connecting plate 20 is fixedly connected to the two lifting blocks 9. A second round rod 21 is installed at one end of the moving plate 15. A groove rod 22 is arranged above the second round rod 21. A guide rod 23 is installed inside the groove rod 22. A slider 24 is slidably connected to the outer surface of the guide rod 23, and the slider 24 is fixedly connected to the second round rod 21. A second spring 25 is sleeved on the outer surface of the guide rod 23. A second connecting plate 26 is installed at one end of the groove rod 22, and the second connecting plate 26 is fixedly connected to the two lifting blocks 9.

[0019] The working principle of the present utility model is as follows: Push the second round rod 21 to move, driving the moving plate 15 to move away from the fixing plate 14. At the same time, the second round rod 21 drives the slider 24 to move and compress the second spring 25. Put the circular ring cleaning block 18 into the hidden groove 17, release the second round rod 21, and the moving plate 15 is pushed to reset by the second spring 25.

[0020] When detecting, press the bottom plate 12 on the land to be detected, hold the gripping rod 3 and push the mounting plate 1 to descend. The mounting plate 1 drives the sensor 5 and the detection needle 6 to descend through the vertical rod 4, so that the detection needle 6 passes through the circular ring cleaning block 18 and the through hole 13 and inserts into the land for acidity and alkalinity detection. At the same time, the vertical rod 4 descends and compresses the first spring 10. When the detection is completed, reset the mounting plate 1, and the vertical rod 4 is pushed to reset by the first spring 10.
