DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] 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; 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; 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. 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 .

[0021] like Figure 1 , Figure 2 , Figure 3 and Fig.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 Fig.11 As shown), this is to prevent the driving wheels 12 arranged on the frame from crushing the crops when the frame moves.

[0022] 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.

[0023] At the same time, driven by the driving assembly, multiple sets of driving wheels 12 can be driven to rotate in the vertical direction, and then the middle frame 1 is driven to move along the planting row of crops through the side frames 2. Moreover, driven by the driving assembly, although the horizontal spacing between the two sets of side frames 2 changes according to the planting spacing of crops during actual use, the driving assembly can adapt to the spacing changes of the side frames 2, that is, the driving assembly can always drive multiple sets of driving wheels 12 to rotate synchronously.

[0024] At the same time, the driving component is intermittently running. When the driving component stops running, the positions of the middle frame 1 and the side frame 2 remain unchanged. At this time, driven by the soil extension component, the probe 3 can move freely in the vertical direction, and then when the probe 3 moves downward, it can penetrate into the soil to a certain depth, and then detect the moisture 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 scraping component, the soil attached to the probe 3 can be cleared, so that in the continuous detection process, the probe 3 can be ensured to be in a clean state before each detection, thereby avoiding the influence of soil residues from the previous detection on subsequent detections, thereby ensuring the accuracy of soil detection data at different positions of the greenhouse, so as to facilitate differentiated irrigation of crop planting positions with different moisture contents, so as to ensure the consistency of crop growth.

[0025] It should be noted that when planting crops in a greenhouse, the light intensity in different areas of the greenhouse may vary depending on the location. The soil evaporation in the area with direct sunlight is large, while the evaporation in the area with insufficient light is relatively small. In addition, uneven air flow in the greenhouse will also affect the soil moisture distribution. The air flow in the area close to the vents is faster and the evaporation is greater, while the air in the area far from the vents is relatively stagnant, the humidity is higher, and the soil moisture evaporates slowly. Among them, the different soil humidity in the greenhouse will affect the nutrient absorption efficiency of the roots, and it is difficult to ensure the consistency of crop growth. Therefore, by continuously detecting different positions in the greenhouse and ensuring the cleanliness of the probe 3 before a single detection, the accuracy of the detection results is guaranteed, thereby improving the detection efficiency.

[0026] In one of the more preferred embodiments, the driving assembly comprises a hollow spline cylinder 6 which is fixedly rotated on the middle frame 1, a group of spline rods 7 are respectively provided at both ends of the hollow spline cylinder 6, the spline rods 7 are fixedly rotated on the side frame 2, and a spline groove for horizontal sliding connection of the spline rods 7 is opened on the hollow spline cylinder 6; A vertical shaft 10 is fixedly rotated on the side frame 2, and a group of vertical bevel gears 9 are coaxially fixed at both ends of the vertical shaft 10. The two groups of vertical bevel gears 9 are respectively meshed and connected with an upper bevel gear 8 and a lower bevel gear 11. The upper bevel gear 8 is coaxially fixed to the spline rod 7, and the lower bevel gear 11 is coaxially fixed to the driving wheel 12.

[0027] like Figure 1 , Figure 2 , Figure 4 and Fig.10 As shown, when the hollow spline cylinder 6 rotates freely in the vertical direction, it can drive the spline rod 7 slidingly arranged thereon to rotate synchronously, wherein, when the horizontal spacing between the two sets of side frames 2 changes, the spline rod 7 slides on the hollow spline cylinder 6, but the hollow spline cylinder 6 can still drive the spline rod 7 to rotate synchronously through the spline groove opened thereon.

[0028] At the same time, a vertical shaft 10 is fixedly rotated on the side 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 fixed thereon, and then drives the lower bevel gear 11 and the driving wheel 12 coaxially arranged with the lower bevel gear 11 to rotate through the vertical bevel gear 9 arranged at the bottom of the vertical shaft 10. When the hollow spline cylinder 6 rotates, it can synchronously drive multiple groups of driving wheels 12 to rotate in the vertical direction, so as to drive the middle frame 1 and the side frame 2 to move along the inter-row channel. In addition, in actual use, crops pass from under the middle frame 1, so when the frame moves, the stems and leaves of the crops will not be bent or damaged.

[0029] Based on the embodiment of the driving assembly, the soil extension assembly includes an axial column 19 coaxially arranged with the central cylinder 13, the axial column 19 is free to move in the vertical direction and freely rotate at the end of the vertical stroke, an inner groove column 24 is fixedly connected to the axial column 19, and a connecting plate 25 is fixedly rotated at one end of the inner groove column 24 away from the axial column 19; One end of the connecting plate 25 away from the inner groove column 24 is fixedly connected to the probe 3 .

[0030] like Figure 1 , Figure 5 and Figure 8 As shown, when the axial column 19 moves freely in the vertical direction, it can drive the inner groove column 24, the connecting plate 25 and the probe 3 arranged below to rise and fall synchronously. 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 that position.

[0031] 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 terminal position of the vertical stroke, thereby driving the inner groove column 24 and the connecting plate 25 fixed thereon to rotate synchronously. The rotation process of the connecting plate 25 drives the annular scraper assembly 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 annular scraper assembly, thereby ensuring the detection accuracy of the probe 3.

[0032] 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; 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; 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.

[0033] 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. 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.

[0034] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 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.

[0035] 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.

[0036] Among them, the directional pin 18 is slidably connected to the axial column 19 through the spiral directional groove 20. In the initial state, the probe 3 is at the maximum height position, and the transverse protrusion 191 is at the junction of the upper annular groove 21 and the vertical connecting groove 23. When the directional pin 18 moves downward, the axial column 19 synchronously follows the directional pin 18 to move downward, thereby driving the transverse protrusion 191 to slide on the vertical connecting groove 23 until the transverse protrusion 191 corresponds to the position of the lower annular groove 22, and the probe 3 follows the axial column 19 to move downward synchronously, thereby allowing the probe 3 to be inserted into the soil to a certain depth.

[0037] Based on the soil extension assembly embodiment, the ring scraper assembly includes two groups of special-shaped rods 30 that move synchronously toward or away from each other in the horizontal direction, and the arc-shaped blocking seat 27 is provided with a groove body 1 for the special-shaped rods 30 to slide through in the horizontal direction; One end of the two groups of special-shaped rods 30 away from the arc-shaped blocking seat 27 is fixedly connected to an inner sharp corner scraper 31 , and the inner sharp corner scraper 31 is in sliding contact with the outer peripheral surface of the probe 3 .

[0038] A limit plate 26 is slidably sleeved on the inner groove column 24, and an inner cavity groove for horizontal sliding of the limit plate 26 is opened on the arc-shaped resistance seat 27, a limit pin 28 is fixedly connected to the side of the limit plate 26 by the special-shaped rod 30, and an eccentric groove 29 for sliding connection of the limit pin 28 is opened on the special-shaped rod 30.

[0039] The inner point scraper 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 point scraper 31 slides in contact with the outer peripheral surface of the probe 3.

[0040] like Figure 5-Figure 9 As shown, when the transverse protrusion 191 is at the junction of the lower annular groove 22 and the vertical connecting groove 23, as the directional pin 18 continues to move downward, the transverse protrusion 191 is already at the lowest position of the vertical connecting groove 23. At this time, the axial column 19 cannot move downward synchronously with the directional pin 18, and then when the directional pin 18 descends, the directional pin 18 slides on the spiral directional groove 20, thereby driving the axial column 19 to rotate and driving the inner groove column 24 to rotate synchronously, wherein a limiting plate 26 is provided on the sliding sleeve of the inner groove column 24, so that the limiting plate 26 can be driven to rotate synchronously through the rotation process of the axial column 19.

[0041] At the same time, when the limit plate 26 rotates with the descent of the directional pin 18, the horizontal position of the special-shaped rod 30 can be adjusted through the multiple groups of eccentric grooves 29 opened on the limit plate 26, thereby changing the horizontal position of the inner pointed corner scraper block 31 on the special-shaped rod 30, so as to drive the inner pointed corner scraper block 31 to contact the outer peripheral surface of the probe 3, so that the annular scraper assembly is in a working state.

[0042] At the same time, the positioning rod 16 drives the directional pin 18 to reciprocate in the vertical direction. When the directional pin 18 moves upward, the transverse protrusion 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 directional pin 18 until the transverse protrusion 191 moves to the top of the vertical connecting groove 23. Subsequently, as the directional pin 18 continues to rise, the directional pin 18 slides on the spiral directional groove 20, thereby driving the axial column 19 to rotate in the opposite direction, so as to drive the inner groove column 24 and the limit plate 26 to rotate synchronously, and change the distance between the two groups of special-shaped rods 30 and the inner sharp corner scraper block 31 through the eccentric groove 29, so as to make the inner sharp corner scraper block 31 away from the probe 3, thereby making the annular scraper assembly in a separated state.

[0043] It should be noted that when the probe 3 follows the axial column 19 to move upward, the annular scraper assembly is in a working state. At this time, the inner pointed corner scraper block 31 is in contact with the outer peripheral surface of the probe 3. When the probe 3 rises, it can move relative to the inner pointed corner scraper block 31, and then the soil attached to the probe 3 is scraped off by the inner pointed corner scraper block 31. When the probe 3 follows the axial column 19 to move downward, the annular scraper assembly is in a separated state, that is, the inner pointed corner scraper block 31 is not in contact with the surface of the probe 3. Therefore, when the probe 3 moves downward and penetrates into the soil, the inner pointed corner scraper block 31 will not provide resistance to the descent process of the probe 3, so as to ensure that the descent process of the probe 3 will not be affected by motion interference.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
