Description

Technical Field

[0001] The present invention relates to the technical field of agricultural environment detection, and particularly to an agricultural facility environment detection device. Background Art

[0002] In modern agriculture, environmental monitoring technology plays a crucial role in increasing crop yields and optimizing resource management. Environmental factors within agricultural facilities, including temperature, humidity, light intensity, and soil moisture, have a significant impact on the growth and health of crops. In particular, soil moisture is a key factor affecting a plant's absorption of water and nutrients.

[0003] Chinese Patent (Publication No.: CN117347593B), this solution specifically includes a moisture sensor for detecting moisture in the air and a soil moisture detection component for detecting moisture in the soil. Both the moisture sensor and the soil moisture detection component are electrically connected to a controller; the soil moisture detection component includes four arc-shaped outer shells arranged in an annular array, and a probe driving component is installed inside each arc-shaped outer shell; when in use, first fix the soil moisture detection component to a stable frame through a fixing cylinder, and insert the soil moisture detection component into the soil. The moisture detection probe inside the soil moisture detection component can detect the moisture in the soil, and the moisture sensor can detect the moisture in the air and transmit the detection information to the controller. The controller transmits the measured data to a computer terminal for the staff to analyze the detection data.

[0004] The above patent detects moisture by inserting a probe into the soil. In an agricultural greenhouse, due to differences in light intensity, the planting positions of crops, and changes in ventilation conditions, there are significant differences in soil moisture in different areas of the greenhouse. Therefore, when effectively detecting the soil in the greenhouse, multiple measurement points need to be selected to avoid the data limitations of a single measurement position. However, existing detection devices are difficult to continuously detect different soil measurement points in the greenhouse, resulting in difficulty in improving the detection efficiency.

[0005] At the same time, during multiple consecutive detections, the movement of the device may cause rolling damage to the stems and leaves of crops. For greenhouses growing different crops, the row spacing of their planting is different, and thus existing detection devices are difficult to be applicable in greenhouses growing different plants. Therefore, an agricultural facility environment detection device is proposed. Summary of the Invention

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] See also Figures 1 to 11 The present invention provides a technical solution: an agricultural facility environment detection device, including a frame and a humidity sensor for detecting soil, the humidity sensor including a probe 3 that penetrates into the soil, the frame consisting of a group of middle frames 1 and a group of side frames 2 respectively arranged on both horizontal sides thereof, the side frames 2 are provided with a plurality of groups of driving wheels 12 for driving the frame to move, the middle frame 1 is provided with an intermediate structure for driving the frame to move at a fixed distance and for the humidity sensor to detect soil humidity multiple times;

[0041] The middle frame 1 is provided with a transverse slide groove 4 for horizontally sliding connection of the side frame 2, the side frame 2 is threadedly connected with bolts, and the middle frame 1 is provided with a plurality of mounting holes 5 for use with the bolts;

[0042] The intermediate measurement structure includes a driving assembly arranged on the side frame 2 and used to drive multiple sets of driving wheels 12 to rotate. The driving wheels 12 rotate on the side frame 2 with a fixed axis. A central cylinder 13 is fixedly connected to the middle of the middle frame 1. The probe 3 is arranged directly below the central cylinder 13, and a soil extension assembly is arranged on the central cylinder 13 to drive the probe 3 to freely rise and fall in the vertical direction.

[0043] The central tube 13 is fixedly connected with an arc-shaped blocking seat 27 , and the arc-shaped blocking seat 27 is provided with a ring scraping component for cleaning the dirt attached to the probe 3 .

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, when the detection device is used, according to the planting spacing of crops in the greenhouse, the spacing between the side frames 2 and the middle frame 1 is adjusted, thereby changing the horizontal spacing between the two sets of side frames 2 and the driving wheels 12 arranged thereon, so that the driving wheels 12 are located in adjacent or inter-adjacent row channel positions (such as Figure 11 As shown), this is to prevent the driving wheels 12 arranged on the frame from crushing the crops when the frame moves.

[0045] Among them, the side frames 2 slide horizontally on the middle frame 1 through the transverse sliding groove 4, and the middle frame 1 is provided with multiple groups of mounting holes 5 for bolting the side frames 2, and then when adjusting the spacing between the driving wheels 12 on the two groups of side frames 2, the side frames 2 are driven to slide on the middle frame 1, and after determining the spacing between the two groups of side frames 2, the bolts are screwed into the corresponding mounting holes 5, so that the side frames 2 are fixed on the middle frame 1 to ensure the stability of the frame when moving.

[0046] Meanwhile, driven by the displacement component, a plurality of groups of drive wheels 12 can be driven to rotate in the vertical direction, and then the middle frame 1 can be driven to move along the planting rows of crops through the side frames 2. Moreover, driven by the displacement component, although the horizontal distance between the two side frames 2 changes according to the planting distance of the crops during actual use, the displacement component can adapt to the change in the distance between the side frames 2, that is, the displacement component can always drive a plurality of groups of drive wheels 12 to rotate synchronously.

[0047] Meanwhile, the displacement component operates intermittently. When the displacement component stops operating, the positions of the middle frame 1 and the side frames 2 remain unchanged. At this time, driven by the soil extending component, the probe 3 can move freely in the vertical direction. Then, when the probe 3 moves downward, it can penetrate into the soil to a certain depth, and then detect the humidity of the soil. And the humidity sensor can transmit the detection data to the terminal. And when the probe 3 moves upward, driven by the ring scraping component, the soil attached to the probe 3 can be removed, so that during continuous detection, it can be ensured that the probe 3 is in a clean state before each detection, thereby avoiding the influence of the soil residue of the previous detection on the subsequent detection, and then ensuring the accuracy of the soil detection data at different positions in the greenhouse, so as to facilitate differential irrigation of the crop planting positions with different water content rates to ensure the consistency of crop growth.

[0048] It should be noted that when planting crops in the greenhouse, the light intensity in different areas of the greenhouse may vary due to location. The evaporation amount of the soil in the direct sunlight area is relatively large, while the evaporation amount in the area with insufficient light is relatively small. Moreover, the uneven air flow in the greenhouse will also affect the soil moisture distribution. The air flow in the area near the ventilation opening is relatively fast, and the evaporation amount is larger, while the air in the area far from the ventilation opening is relatively stagnant, with a higher humidity and a slower evaporation rate of the soil moisture. Among them, the different soil humidities in the greenhouse will affect the nutrient absorption efficiency of the roots, and it is difficult to ensure the consistency of crop growth. Therefore, through continuous detection of different positions in the greenhouse and ensuring the cleanliness of the probe 3 before each single detection, the accuracy of the detection results is guaranteed, thereby improving the detection efficiency.

[0049] In a relatively preferred embodiment, the displacement component includes a hollow spline cylinder 6 that rotates on the middle frame 1 with a fixed axis. A set of spline rods 7 are respectively provided at both ends of the hollow spline cylinder 6. The spline rods 7 rotate on the side frames 2 with a fixed axis, and a spline groove for the horizontal sliding connection of the spline rods 7 is provided on the hollow spline cylinder 6;

[0050] A vertical shaft 10 rotates on the side frame 2 with a fixed axis. A set of vertical bevel gears 9 are coaxially fixed at both ends of the vertical shaft 10. The two sets of vertical bevel gears 9 are respectively meshed with an upper bevel gear 8 and a lower bevel gear 11. The upper bevel gear 8 is coaxially fixed with the spline rod 7, and the lower bevel gear 11 is coaxially fixed with the drive wheel 12.

[0051] As Figure 1 , Figure 2 , Figure 4 and Figure 10 shown, when the hollow spline tube 6 rotates freely in the vertical direction, it can drive the spline rod 7 slidably arranged thereon to rotate synchronously. Among them, when the horizontal distance between the two sets of side position frames 2 changes, the spline rod 7 slides on the hollow spline tube 6. However, the hollow spline tube 6 can still drive the spline rod 7 to rotate synchronously through the spline grooves formed thereon.

[0052] At the same time, a vertical shaft 10 is rotatably fixed on the side position frame 2, and vertical bevel gears 9 are coaxially fixed at both ends of the vertical shaft 10. The spline rod 7 drives the vertical shaft 10 to rotate through the upper bevel gear 8 fixedly arranged thereon. Then, the lower bevel gear 11 and the driving wheel 12 coaxially arranged with the lower bevel gear 11 are driven to rotate through the vertical bevel gear 9 arranged at the bottom of the vertical shaft 10. Then, when the hollow spline tube 6 rotates, a plurality of groups of driving wheels 12 can be synchronously driven to rotate in the vertical direction to drive the middle position frame 1 and the side position frames 2 to move along the row channel. And, in the actual use process, crops pass through below the middle position frame 1. Therefore, when the vehicle frame moves, it will not cause bending damage to the stems and leaves of the crops.

[0053] On the basis of the embodiment of the displacement driving assembly, the soil extending assembly includes an axial column 19 coaxially arranged with the central cylinder 13. The axial column 19 moves freely in the vertical direction and rotates freely at the end of the vertical stroke. An inner groove column 24 is fixedly connected to the axial column 19. One end of the inner groove column 24 away from the axial column 19 is rotatably fixed with an adapter plate 25;

[0054] A fixed connection is provided between one end of the adapter plate 25 away from the inner groove column 24 and the probe 3.

[0055] As Figure 1 , Figure 5 and Figure 8 shown, when the axial column 19 moves freely in the vertical direction, it can drive the inner groove column 24, the adapter plate 25 and the probe 3 arranged below to move up and down synchronously. Among them, when the probe 3 moves downward, it can penetrate into the soil to a certain depth, and then detect the humidity of the soil at this position.

[0056] At the same time, when the probe 3 penetrates into the soil, the axial column 19 can rotate freely in the horizontal direction at the end position of the vertical stroke, and then drive the inner groove column 24 and the adapter plate 25 fixedly arranged thereon to rotate synchronously. Through the rotation process of the adapter plate 25, the ring scraping assembly is driven to operate. When the axial column 19 drives the probe 3 to move upward, the soil attached to the probe 3 can be scraped off by the ring scraping assembly, so as to ensure the detection accuracy of the probe 3.

[0057] Furthermore, the soil extension assembly further comprises a positioning rod 16 that can freely move in the vertical direction, and a directional pin 18 is fixedly connected to one side of the positioning rod 16 facing the axial column 19, and a spiral directional groove 20 for the directional pin 18 to be slidably connected is provided on the axial column 19;

[0058] The bottom end of the axial column 19 includes an integrally formed transverse convex portion 191, and the central tube 13 is provided with an upper annular groove 21 and a lower annular groove 22 for the transverse convex portion 191 to slide horizontally;

[0059] The central tube 13 is also provided with a vertical connecting groove 23 for the lateral protrusion 191 to slide and connect in the vertical direction. Both ends of the vertical connecting groove 23 are respectively connected to the upper annular groove 21 and the lower annular groove 22.

[0060] The hollow spline cylinder 6 is provided with a driven gear 32, which is connected to the adjustment rod 14 in a transmission manner. The adjustment rod 14 rotates on the center frame 1 and rotates freely in the vertical direction.

[0061] The adjusting rod 14 is fixedly connected with an adjusting pin 15 , the positioning rod 16 is provided with a horizontal adjusting groove 17 for the adjusting pin 15 to slide horizontally, and the central tube 13 is provided with a rectangular through groove for the positioning rod 16 to slide through in a vertical direction.

[0062] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a driven gear 32 is fixedly provided on the hollow spline cylinder 6, and the driven gear 32 is transmission-connected to the adjusting rod 14, and the adjusting rod 14 and the driven gear 32 rotate alternately. In actual use, the meshing between the incomplete gear and the complete gear can drive the two to rotate alternately, wherein, when the adjusting rod 14 rotates in the vertical direction, it can drive its end portion arranged on the adjusting pin 15 to rotate synchronously, thereby changing the horizontal height of the adjusting pin 15.

[0063] At the same time, the positioning rod 16 is slidably connected to the center tube 13 through a rectangular through groove, and the adjustment pin 15 is slidably connected to the positioning rod 16 through a horizontal adjustment groove 17. Therefore, when the horizontal height of the adjustment pin 15 changes with the rotation of the positioning rod 14, the positioning rod 16 and the directional pin 18 fixed thereon can be driven to reciprocate in the vertical direction.

[0064] Among them, the orientation pin 18 is slidably connected to the axial column 19 through the spiral orientation groove 20. In the initial state, the probe 3 is at the maximum height position, and the horizontal convex part 191 is at the junction of the upper annular groove 21 and the vertical connecting groove 23. When the orientation pin 18 moves downward, the axial column 19 synchronously follows the orientation pin 18 downward, thereby driving the horizontal convex part 191 to slide on the vertical connecting groove 23 until the horizontal convex part 191 corresponds to the position of the lower annular groove 22. Moreover, the probe 3 synchronously moves downward with the axial column 19, thereby inserting the probe 3 into the soil to a certain depth.

[0065] Based on the embodiment of the soil-pushing component, the ring scraping component includes two groups of special-shaped rods 30 that move synchronously towards or away from each other in the horizontal direction. The arc-shaped blocking seat 27 is provided with a groove body one through which the special-shaped rods 30 slide horizontally.

[0066] Both ends of the two groups of special-shaped rods 30 far away from the arc-shaped blocking seat 27 are fixedly connected with inner sharp-angle scraping blocks 31, and the inner sharp-angle scraping blocks 31 are in sliding contact with the outer peripheral surface of the probe 3.

[0067] A limiting disk 26 is slidably sleeved on the inner groove column 24, and the arc-shaped blocking seat 27 is provided with an inner cavity groove for the limiting disk 26 to slide horizontally. A limiting pin 28 is fixedly connected to the side of the special-shaped rod 30 facing the limiting disk 26, and an eccentric groove 29 for the limiting pin 28 to slide and connect is provided on the special-shaped rod 30.

[0068] The inner sharp-angle scraping block 31 does not contact the outer peripheral surface of the probe 3 when the probe 3 moves downward, and when the probe 3 moves upward, the inner sharp-angle scraping block 31 is in sliding contact with the outer peripheral surface of the probe 3.

[0069] As Figures 5 to 9 shown, when the horizontal convex part 191 is at the junction of the lower annular groove 22 and the vertical connecting groove 23, as the orientation pin 18 continues to move downward, the horizontal convex part 191 is already at the lowest position of the vertical connecting groove 23. At this time, the axial column 19 cannot follow the orientation pin 18 to move downward synchronously. Therefore, when the orientation pin 18 descends, the orientation pin 18 slides on the spiral orientation groove 20, thereby being able to drive the axial column 19 to rotate and drive the inner groove column 24 to rotate synchronously. Among them, a limiting disk 26 is slidably sleeved on the inner groove column 24, so that the limiting disk 26 can be driven to rotate synchronously through the rotation process of the axial column 19.

[0070] Meanwhile, when the limiting disk 26 rotates as the orientation pin 18 descends, the horizontal position of the special-shaped rod 30 can be adjusted through the multiple groups of eccentric grooves 29 provided on the limiting disk 26, thereby changing the horizontal position of the inner sharp-angle scraping block 31 on the special-shaped rod 30 to drive the inner sharp-angle scraping block 31 to contact the outer peripheral surface of the probe 3, so that the ring scraping component is in a working state.

[0071] Meanwhile, the positioning rod 16 drives the orientation pin 18 to reciprocate in the vertical direction. When the orientation pin 18 moves upward, at this time, the horizontal convex part 191 is at the junction of the vertical connecting groove 23 and the lower annular groove 22. Therefore, the axial column 19 can drive the inner groove column 24 and the probe 3 to move upward synchronously with the orientation pin 18 until the horizontal convex part 191 moves to the uppermost part of the vertical connecting groove 23. Subsequently, as the orientation pin 18 continues to rise, the orientation pin 18 slides on the spiral orientation groove 20, thereby driving the axial column 19 to rotate in the reverse direction to drive the inner groove column 24 and the limit disk 26 to rotate synchronously, and changing the distance between the two groups of special-shaped rods 30 and the inner sharp-angle scraping block 31 through the eccentric groove 29, so that the inner sharp-angle scraping block 31 moves away from the probe 3, and further makes the ring scraping assembly in a separated state.

[0072] It should be noted that when the probe 3 moves upward following the axial column 19, the ring scraping assembly is in a working state. At this time, the inner sharp-angle scraping block 31 contacts the outer peripheral surface of the probe 3. When the probe 3 rises, relative movement can occur between the probe 3 and the inner sharp-angle scraping block 31. Therefore, the soil attached to the probe 3 is scraped off by the inner sharp-angle scraping block 31. When the probe 3 moves downward following the axial column 19, the ring scraping assembly is in a separated state, that is, the inner sharp-angle scraping block 31 does not contact the surface of the probe 3. Therefore, when the probe 3 moves downward and penetrates into the soil, the inner sharp-angle scraping block 31 will not provide resistance to the descending process of the probe 3 to ensure that the descending process of the probe 3 is not interfered with by movement.
