Description

Technical Field

[0001] This utility model relates to the field of soil fertilization technology, and in particular to a vehicle-mounted soil water and fertilizer delivery probe. Background Technology

[0002] Crops are the various plants cultivated in agriculture. They include two main categories: food crops and cash crops (oilseed crops, vegetable crops, flowers, grasses, and trees). The saying "Food is the first necessity of the people" expresses the relationship between humans and food; a balanced diet is essential for human health. The growth of crops relies on scientific and technological production techniques, as well as modern industrial machinery that assists agricultural production. Fertilizers are frequently applied during crop cultivation. To ensure normal crop growth and rapid nutrient absorption, vehicle-mounted water and fertilizer spraying devices are used to apply nutrient fertilizers.

[0003] In current technologies, soil sensor probes are typically installed on fertilizer delivery vehicles to ensure fertilization accuracy when spraying water and fertilizer onto soil. However, these probes lack protection and are easily damaged by contact with hard objects when inserted into the soil, resulting in low safety and reduced lifespan. Therefore, it is necessary to provide a vehicle-mounted soil water and fertilizer delivery probe to solve the aforementioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in order to ensure the accuracy of fertilization when spraying water and fertilizer on soil, the fertilizer vehicle is usually equipped with a soil sensor probe structure. However, the structure lacks protection and is easily damaged when it is inserted into the soil due to contact with hard objects, resulting in low safety and affecting service life. In view of the above-mentioned defects of the prior art, a vehicle-mounted soil water and fertilizer delivery probe is provided, including a rotating arm, an outer protective cone plate fixedly installed at the bottom of the mounting housing, and a V-shaped plate fixedly installed at the bottom of the inner cavity of the outer protective cone plate. This invention features an outer protective cone plate on the probe of a soil nitrogen, phosphorus, and potassium sensor, which enhances the protection of the probe. The outer protective cone plate also has a V-shaped plate inside. Furthermore, by activating a third motor, an extension arm connected to its output shaft rotates the outer protective cone plate, preventing soil from adhering to the inside of the outer protective cone plate and affecting subsequent soil testing results. This ensures accurate fertilization and solves the technical problem in existing technologies where soil sensor probes are typically installed on fertilization vehicles to ensure fertilization accuracy. However, these probes lack protection and are easily damaged when inserted into the soil due to contact with hard objects, resulting in low safety and reduced service life.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a vehicle-mounted soil water and fertilizer delivery probe, comprising a rotating arm, a connecting groove at one end of the rotating arm, a connecting rod inserted into the connecting groove, a third motor embedded at one end of the connecting rod, an extension arm fixedly connected to the output shaft of the third motor, a bracket fixedly mounted on the upper surface of the extension arm, a hydraulic telescopic rod fixedly mounted inside the bracket, a mounting housing fixedly connected to the output end of the hydraulic telescopic rod, a soil nitrogen, phosphorus, and potassium sensor fixedly mounted inside the mounting housing, and an outer protective cone plate fixedly mounted at the bottom of the mounting housing, with a V-shaped plate fixedly mounted at the bottom of the inner cavity of the outer protective cone plate.

[0006] In a further configuration, the outer protective cone plate is located outside the soil nitrogen, phosphorus, and potassium sensor, which includes a probe disposed at the bottom.

[0007] Further, the upper surface of the rotating arm is provided with a slide rail and two fixed seats. A second motor is fixedly installed on the front surface of the fixed seat. The output shaft of the second motor passes through the fixed seat and is fixedly connected to a lead screw. A movable block that passes through the slide rail is screwed to the outside of the lead screw. The bottom of the movable block is fixedly connected to the connecting rod.

[0008] Furthermore, one end of the lead screw is rotatably connected to the fixed base, and the movable block is slidably connected to the slide rail.

[0009] Furthermore, a fixing plate is provided above the rotating arm, and four fixing holes are evenly opened on the upper surface of the fixing plate. A first motor is fixedly installed on the upper surface of the fixing plate, and the output shaft of the first motor passes through the fixing plate and is rotatably connected to the rotating arm.

[0010] Furthermore, a processor is fixedly mounted on the upper surface of the fixing plate, and the processor is electrically connected to the soil nitrogen, phosphorus and potassium sensor.

[0011] Compared with related technologies, the vehicle-mounted soil water and fertilizer delivery probe provided by this utility model has the following beneficial effects:

[0012] This utility model provides a vehicle-mounted soil water and fertilizer delivery probe. An outer protective cone plate is provided outside the probe of the soil nitrogen, phosphorus, and potassium sensor to improve the protection of the probe. A V-shaped plate is provided inside the outer protective cone plate. By starting a third motor, the extension arm connected to its output shaft is driven to rotate the outer protective cone plate, thereby preventing soil from adhering to the inside of the outer protective cone plate and affecting the results of soil re-detection, ensuring the accuracy of fertilization. This solves the technical problem in the prior art that when spraying water and fertilizer on the soil, in order to ensure the accuracy of fertilization, soil sensor probes are usually equipped on fertilizer vehicles. However, their structures lack protection and are easily damaged when inserted into the soil due to contact with hard objects, resulting in low safety and affecting service life.

[0013] This utility model provides a vehicle-mounted soil water and fertilizer delivery probe. By starting a second motor, the lead screw connected to its output shaft is rotated, thereby controlling the movable block on the outside to move the soil nitrogen, phosphorus and potassium sensor connected through the connecting rod and extension arm. This allows the detection range to be expanded as needed, improving practicality. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0019] Example 1:

[0020] like Figure 1-3As shown, a vehicle-mounted soil water and fertilizer delivery probe of this utility model includes a rotating arm 4. One end of the rotating arm 4 is provided with a connecting groove 18. A connecting rod 19 is inserted into the connecting groove 18. A third motor 20 is embedded in one end of the connecting rod 19. The output shaft of the third motor 20 is fixedly connected to an extension arm 6. A bracket 7 is fixedly installed on the upper surface of the extension arm 6. A hydraulic telescopic rod 10 is fixedly installed inside the bracket 7. A mounting housing 8 is fixedly connected to the output end of the hydraulic telescopic rod 10. A soil nitrogen, phosphorus and potassium sensor 15 is fixedly installed inside the mounting housing 8. An outer protective cone plate 9 is fixedly installed at the bottom of the mounting housing 8. A V-shaped plate 17 is fixedly installed at the bottom of the inner cavity of the outer protective cone plate 9.

[0021] like Figure 1-2 As shown, the outer protective cone plate 9 is located outside the soil nitrogen, phosphorus and potassium sensor 15, which includes a probe 16 disposed at the bottom.

[0022] In practice, an outer protective cone plate 9 is provided outside the probe 16 of the soil nitrogen, phosphorus and potassium sensor 15 to improve the protection of the probe 16. A V-shaped plate 17 is provided inside the outer protective cone plate 9. By starting the third motor 20, the extension arm 6 connected to its output shaft is driven to rotate the outer protective cone plate 9, thereby preventing soil from adhering to the inside of the outer protective cone plate 9 and affecting the results of soil re-detection, ensuring the accuracy of fertilization. This solves the technical problem in the prior art that when spraying water and fertilizer on the soil, in order to ensure the accuracy of fertilization, a soil sensor probe structure is usually equipped on the fertilizer vehicle. However, its structure lacks protection and is easily damaged when it is inserted into the soil due to contact with hard objects, resulting in low safety and affecting the service life.

[0023] Example 2:

[0024] like Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution: the upper surface of the rotating arm 4 is respectively provided with a slide rail 21 and two fixed seats 11. A second motor 5 is fixedly installed on the front surface of the front fixed seat 11. The output shaft of the second motor 5 passes through the fixed seat 11 and is fixedly connected to a lead screw 12. A movable block 13 passing through the slide rail 21 is screwed to the outside of the lead screw 12. The bottom of the movable block 13 is fixedly connected to the connecting rod 19. One end of the lead screw 12 is rotatably connected to the fixed seat 11. The movable block 13 is slidably connected to the slide rail 21. A fixed plate 2 is provided above the rotating arm 4. Four fixed holes 3 are evenly opened on the upper surface of the fixed plate 2. A first motor 1 is fixedly installed on the upper surface of the fixed plate 2. The output shaft of the first motor 1 passes through the fixed plate 2 and is rotatably connected to the rotating arm 4. A processor 14 is fixedly installed on the upper surface of the fixed plate 2. The processor 14 is electrically connected to the soil nitrogen, phosphorus and potassium sensor 15.

[0025] In practice, by starting the second motor 5, the lead screw 12 connected to its output shaft is rotated, thereby controlling the movable block 13 on the outside to move the soil nitrogen, phosphorus and potassium sensor 15 connected to the connecting rod 19 and the extension arm 6. This allows the detection range to be expanded as needed, improving practicality.

[0026] This technical solution fixes the probe to the fertilizer applicator. During use, activating the hydraulic telescopic rod 10 moves the mounting housing 8 connected to its output end, causing the soil nitrogen, phosphorus, and potassium sensor 15 and the outer protective cone plate 9 to move downwards. This allows the outer protective cone plate 9 and the probe 16 to insert into the soil, detecting the nitrogen, phosphorus, and potassium content, thus achieving intelligent control of water and fertilizer application. Activating the first motor 1 rotates the rotating arm 4 connected to its output shaft, and the second motor 5 rotates the lead screw 12 connected to its output shaft, causing the outer movable block 13 to move the soil nitrogen, phosphorus, and potassium sensor 15, connected to the connecting rod 19 and the extension arm 6, thereby expanding the detection range as needed. Using the V-shaped plate 17 and activating the third motor 20, the extension arm 6 connected to its output shaft rotates the outer protective cone plate 9 and the soil nitrogen, phosphorus, and potassium sensor 15, causing the soil in the gap between the probe 16 and the outer protective cone plate 9 to fall out.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
