[0047] The soil taking unit is slidably installed inside the pesticide spraying unit.

[0048] The soil taking unit is slidably installed on the support frame 1, and a plurality of soil taking cavities are arranged on the soil taking unit.

[0049] The soil taking unit comprises a material receiving disc 30 arranged along a vertical axis, the material receiving disc 30 is upwardly open, and a plurality of baffles 31 are fixed on the material receiving disc 30 along a radial direction of the material receiving disc 30.

[0054] A spraying barrel 15 is arranged outside the extrusion cylinder 16.

[0058] A medicine storage cylinder 32 is fixedly arranged on the support frame 1. The medicine storage cylinder 32 is connected to the medicine spraying unit through a hose 33.

[0059] The medicine storage cylinder 32 is connected to the medicine storage chamber through the hose 33. When the pressure in the medicine storage chamber decreases, the liquid medicine in the medicine storage cylinder 32 is sucked into the medicine storage chamber through the hose 33.

[0060] A plurality of first sliding blocks 17 are fixedly arranged on the extrusion cylinder 16 along the vertical direction. The first sliding blocks 17 are fixedly connected to the driving unit.

[0061] A plurality of second guide grooves 24 corresponding to the first sliding blocks 17 are circumferentially arranged on the bottom of the spraying barrel 15. The lower ends of the first sliding blocks 17 are slidably connected to the corresponding second guide grooves 24.

[0062] The soil sampling unit comprises a sampling barrel 21 coaxial with the extrusion cylinder 16 and spaced apart from the extrusion cylinder 16. The sampling barrel 21 is slidably connected to the extrusion cylinder 16.

[0063] The clamping unit is arranged in multiple groups in an up-down manner, each group of clamping units comprises multiple slide rods 23 corresponding to the first slide blocks 17, the slide rods 23 are arranged along the radial direction of the sampling barrel 21, the slide rods 23 are in sliding connection with the sampling barrel 21, the inner and outer ends of the slide rods 23 are located on the inner and outer sides of the sampling barrel 21 respectively, one end of each slide rod 23 located inside the sampling barrel 21 is fixedly installed with an arc-shaped block 22, springs are installed between the arc-shaped block 22 and the side wall of the sampling barrel 21, one end of the spring is fixed on the arc-shaped block 22, and the other end of the spring is fixedly installed on the sampling barrel 21.

[0064] The bottom of the spraying barrel 15 and the cutting knife 27 are both provided with a vertical avoiding hole 25, the diameter of the avoiding hole 25 is greater than the diameter of the sampling barrel 21, and the bottom of the spraying barrel 15 and the cutting knife 27 are both provided with multiple avoiding grooves 26 corresponding to the first slide blocks 17, and the avoiding grooves 26 are communicated with the avoiding hole 25.

[0065] The driving unit comprises a support shaft 6, and a fixed block 2 is fixedly installed on the support shaft 6.

[0066] A sliding block 4 is in sliding connection with the support shaft 6, the sliding block 4 is located below the support shaft 6, the support frame 1 is provided with a vertical sliding groove, a guide rod 5 is fixedly installed on the sliding block 4, and the tail end of the guide rod 5 is slidingly arranged in the sliding groove.

[0067] A first spring 7 is sleeved on the support shaft 6 between the fixed block 2 and the sliding block 4, the upper end of the first spring 7 is fixed to the bottom of the fixed block 2, and the lower end of the first spring 7 is fixed to the upper portion of the sliding block 4.

[0068] A bidirectional electric telescopic rod 12 is fixedly installed on the support frame 1, both telescopic ends of the bidirectional electric telescopic rod 12 are vertically arranged, a vertical second vertical rod 14 is rotatably installed on the lower telescopic end of the bidirectional electric telescopic rod 12, and the lower end of the second vertical rod 14 is fixedly connected with the sampling barrel 21.

[0069] A rotating handle (not shown in the figure) can be arranged on the second vertical rod 14.

[0070] When soil sampling and spraying are required, the second vertical rod 14 is rotated, causing the slide bar 23 to pivot away from the escape groove 26. This allows the bidirectional electric telescopic rod 12 to push the sampling bucket 21 downward via the second vertical rod 14, and the escape groove 26 can drive the spray bucket 15 downward, allowing the first slide block 17 to penetrate the soil. It is important to note that the arc of the first slide block 17 is greater than the rotation angle of the slide bar 23. Even after the slide bar 23 pivots away from the escape groove 26, the first slide block 17 remains in contact with the slide bar 23.

[0071] When the spraying is completed and the soil is taken, the second vertical rod 14 is rotated in the opposite direction again, so that the sliding rod 23 corresponds to the avoidance groove 26, and the bidirectional electric telescopic rod 12 extends to drive the sampling barrel 21 to move downward, and the sliding rod 23 in the sampling barrel 21 gradually disengages from the avoidance groove 26, and then moves outward, loosening the sample soil, so that the sample soil in the sliding rod 23 leaves the sliding rod 23 one by one.

[0072] The extrusion unit includes a connecting block 8 , which is fixedly mounted on the lower end of the slider 4 .

[0073] A support plate 11 is fixedly mounted on the support frame 1. The support plate 11 is provided with a plurality of first guide grooves 10 extending radially along the support plate 11. A mounting seat is slidably mounted on each of the first guide grooves 10. A connecting rod 9 is hingedly mounted on each of the mounting seats. The upper end of the connecting rod 9 is hingedly connected to the connecting block 8. A vertical telescopic rod 13 is fixedly mounted on the lower end of each of the mounting seats. The lower end of the telescopic rod 13 is fixedly mounted on the first sliding block 17.

[0074] The lower end of the support frame 1 can be installed with walking wheels (not shown in the figure) to facilitate the movement of the device.

[0075] Before using the device, the medicine storage cylinder 32 is filled with medicine liquid.

[0076] The sampling barrel 21 is located within the spray barrel 15. The lower telescopic end of the bidirectional electric telescopic rod 12 is retracted, while the upper telescopic end is extended but not at its longest position. The upper telescopic end of the bidirectional electric telescopic rod 12 is extended to the middle position of its displacement, and the first spring 7 is compressed. At this time, the first sliding block 17 is at the middle position of its displacement, the diameter of the extrusion cylinder 16 is at an intermediate size, and the medicine storage chamber is filled with liquid medicine. The sliding rod 23 is at its outermost position of its displacement, but the outer end of the sliding rod 23 does not contact the first sliding block 17.

[0077] The first electric telescopic rod 28 is in a retracted state, and the second electric telescopic rod 29 is in a retracted state. The receiving tray 30 is in a state away from the spray barrel 15.

[0078] At the same time, the sliding rod 23 and the avoidance groove 26 are in a staggered state.

[0079] To use the device, it is moved to an experimental field. The lower end of the bidirectional electric telescopic rod 12 is activated, pushing the sampling bucket 21 downward via the second vertical rod 14. At this point, the slide bar 23 is offset from the escape groove 26. Therefore, when the bidirectional electric telescopic rod 12 pushes the sampling bucket 21 downward via the second vertical rod 14, the escape groove 26 can drive the spraying bucket 15 downward, allowing the first sliding block 17 to penetrate the soil.

[0080] When the first sliding block 17 is inserted into the soil, the soil at the slide bar 23 will move upward along the slide bar 23 and enter the slide bar 23. An elastic protective sleeve can be installed at the spring installed on the arc block 22 so that the arc block 22 can move smoothly in the soil.

[0081] When the lower telescopic rod of the bidirectional electric telescopic rod 12 reaches its lowest point, the telescopic rod above it is activated, causing it to retract. This contraction of the bidirectional electric telescopic rod 12 drives the connecting block 8 downward. As the connecting block 8 moves downward, it pushes the telescopic rod 13, via the connecting rod 9, along the first guide groove 10, away from the axis of the support shaft 6. The telescopic rod 13 then drives the first sliding block 17 outward along the second guide groove 24.

[0082] As the first sliding block 17 moves away from the axis of the support shaft 6, the diameter of the extrusion barrel 16 gradually increases due to its circumferential elasticity, and the extrusion barrel 16 expands outward. As the diameter of the extrusion barrel 16 increases, the volume of the medicine storage chamber gradually decreases, and the medicine liquid in the medicine storage chamber is squeezed out of the medicine outlet 19 and sprayed into the soil.

[0083] When the telescopic rod above the bidirectional electric telescopic rod 12 shortens to its shortest position, it extends, driving the connecting block 8 upward. Similarly, the upward movement of the connecting block 8 drives the first sliding block 17, via the connecting rod 9, toward the axis of the spray barrel 15. The diameter of the extrusion barrel 16 gradually decreases, the volume of the medicine storage chamber gradually increases, and the pressure gradually decreases. The liquid in the medicine storage barrel 32 is drawn into the medicine storage chamber via the hose 33.

[0084] When the telescopic rod above the bidirectional electric telescopic rod 12 extends to the middle position, it continues to extend, driving the first sliding block 17 to continue to move inward. The first sliding block 17 contacts the corresponding sliding rod 23, pushing the sliding rod 23 to move in the direction close to the axis of the sampling barrel 21. At the same time, the sliding rod 23 drives the arc blocks 22 to move in the direction close to each other. The arc blocks 22 will squeeze the soil between the arc blocks 22 and clamp the soil between the arc blocks 22 on the same layer.

[0085] After the above actions are completed, the telescopic rod below the bidirectional electric telescopic rod 12 is started to retract, and the bidirectional electric telescopic rod 12 drives the spray barrel 15 and the sampling barrel 21 to move upward as a whole, out of the soil and located at a certain height above the soil.

[0086] Subsequently, the second electric telescopic rod 29 is activated to extend, causing the receiving tray 30 to move downward. When the second electric telescopic rod 29 is extended downward to its maximum distance, the height of the receiving tray 30 from the support frame 1 is greater than the height of the lowest end of the soil-extracting unit from the support frame 1 when the soil-extracting unit is moved to the lowest position. Subsequently, the first electric telescopic rod 28 is extended, causing the soil-extracting unit to move directly below the soil-extracting unit.

[0087] The second vertical rod 14 is rotated so that the sliding rod 23 corresponds to the avoidance groove 26, and the bidirectional electric telescopic rod 12 is extended to drive the sampling barrel 21 to move downward. The sliding rod 23 in the sampling barrel 21 gradually disengages from the avoidance groove 26 and moves outward. The sample soil from deeper depth to shallower depth is loosened by the arc block 22 in turn, so that the sample soil in the arc block 22 leaves the arc block 22 in turn.

[0088] At the same time, the motor rotates, driving the different soil receiving cavities of the soil receiving unit to rotate in turn to the bottom of the soil sampling unit. Soil samples of different depths are discharged into different soil receiving cavities, which is convenient for subsequent inspection operations and can make subsequent inspection results more accurate.

[0089] After the above-mentioned action is completed, the motor stops rotating, the first electric telescopic rod 28 is activated to retract, and the first electric telescopic rod 28 is shortened so that the soil receiving unit is away from the soil taking unit. The second electric telescopic rod 29 is activated, and the second electric telescopic rod 29 drives the receiving tray 30 to move upward and reset.

[0090] The second vertical rod 14 is rotated in the opposite direction again, so that the sliding rod 23 is offset from the avoidance groove 26 .

[0091] Start the telescopic rod above the two-way electric telescopic rod 12 and shorten it to half of its displacement, that is, the initial state. It should be noted that a pressure valve is installed at the medicine outlet 19, and the above operation will not cause the medicine liquid in the medicine storage chamber to spray out.

[0092] Move the device and repeat the above operation to inject medicine and take samples at different positions.

[0093] After the entire test field has been injected with the drug, the soil can be turned over so that all the soil is evenly mixed with the injected soil.

[0094] Through the above steps, each time a spray repair treatment is carried out, soil samples can be collected from different locations throughout the test field after the previous spray treatment. Finally, the soil samples after multiple sprayings can be compared and analyzed, eliminating the problem of small sample sizes or inconsistent sampling locations that may affect the final test results.

[0095] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
