Description

Technical Field

[0001] The present invention relates to the field of crop monitoring equipment, and in particular to a monitoring system for the underground growth status of intercropping of cereals and beans. Background Art

[0002] Grain-bean intercropping involves planting both grasses and legumes on the same plot of land. This approach leverages the deep rooting ability of grasses to increase soil organic matter content and retain moisture. Legumes also utilize rhizobia to absorb nitrogen from the air, reducing nitrogen loss from the soil. With the continuous advancement of agricultural technology, intercropping has become increasingly widespread in agricultural production. Grain-bean intercropping is a common intercropping practice that fully utilizes land resources and improves crop yield and quality.

[0003] At present, monitoring the underground growth status of crops in intercropped grass and beans usually requires regular use of excavation equipment to dig out crop samples for testing, and then observing the growth status of their root systems; then using humidity, temperature, nutrient and other probes to regularly monitor the root soil conditions; the above operations together form a complete monitoring system.

[0004] Current monitoring systems for underground growth status of grass-bean intercropping typically require digging up the target plant twice. However, due to the different spacing between adjacent crops, it is impossible to accurately dig out both plants simultaneously using existing digging equipment, resulting in low work efficiency.

DETAILED DESCRIPTION

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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 making creative efforts are within the scope of protection of the present invention.

[0084] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0085] like Figure 1 、 Figure 2 、 Figure 3 and Figure 12 As shown, the monitoring system for the underground growth status of intercropping of wheat and beans comprises: a cart 12, the bottom of which is mounted with a roller 121, and a push rod 122 is also mounted on the cart 12. When in use, the cart 12 is pushed by holding the push rod 122 to move the entire device. The system also comprises: a mounting base 13, a first gear 14, a second gear 15, a second motor 16, a rotating base 17, a counterweight 18, a stand 21, a lifting base 22, and a second oil cylinder 23. The mounting base 13 is mounted on the upper surface of the cart 12, and the mounting base 13 is a hollow structure. The first gear 14 is rotatably mounted in the mounting base 13, and the second gear 15 is rotatably mounted in the mounting base 13. The second gear 15 is meshed with the first gear 14, and the diameter of the second gear 15 is larger than the diameter of the first gear 14. When the first gear 14 rotates, it can drive the second gear 15 to rotate synchronously, thereby increasing torque, reducing rotation speed, and improving stability. The second motor 16 is mounted on the cart 12. The output end of the second motor 16 extends into the mounting base 13 and is connected to the first gear 14. Turning on the second motor 16 can drive the first gear 14 to rotate. The rotating base 17 is mounted on the mounting base 13 and is connected to the second gear 15. The rotation of the second gear 15 can drive the rotating base 17 to rotate synchronously. The counterweight 18 is mounted on the side of the rotating base 17 away from the outer shell 2. The counterweight 18 is used to balance the weight at both ends of the rotating base 17 to prevent the entire device from tipping over. The vertical frame 21 is mounted on the cart 12 and is located on the side away from the counterweight 18. The lifting base 22 is slidably mounted on the vertical frame 21. The second oil cylinder 23 is mounted on the vertical frame 21, and the output end of the second oil cylinder 23 is connected to the lifting base 22. Turning on the second oil cylinder 23 can drive the lifting base 22 to move along the axial direction of the vertical frame 21.

[0086] like Figure 1 、 Figure 2 and Figure 3 As shown, the monitoring system for the underground growth status of intercropping of wheat and beans also includes: a frame 1, a shell 2, support rods 3, a movable frame 4 and an excavation mechanism 5. The shell 2 is installed in the middle of the frame 1. The shell 2 is connected to the lifting seat 22. When the lifting seat 22 moves up and down along the axis of the vertical frame 21, the shell 2 and the frame 1 can move up and down together. In this embodiment, the frame 1 is a rectangular frame with an open center. The frame 1 is used to select the crops to be excavated. The shell 2 is used as a boundary. The two crops to be excavated are respectively located in the space inside the frame 1 on both sides of the shell 2. There are two support rods 3, which are symmetrically mounted on the frame 1 and pass through the shell 2. There are two movable frames 4, each mounted on the support rods 3. The two movable frames 4 are respectively located on both sides of the shell 2. In this embodiment, the two support rods 3 are provided with threads. The two support rods 3 are symmetrical with each other, ensuring that the threaded portions on the two support rods 3 correspond to the two movable frames 4. The two movable frames 4 are respectively threadedly connected to the threaded portion of one of the support rods 3 and are slidably connected to the non-threaded portion of the other support rod 3. When one of the support rods 3 is controlled to rotate, it can drive one of the mobile frames 4 to move along the axial direction of the support rod 3, while the other support rod 3 is used to limit the mobile frame 4 to maintain stability. The digging mechanism 5 is installed on the mobile frame 4. The digging mechanism 5 is used to dig the selected crop plants.

[0087] When the above structure is in use, the cart 12 is pushed to move along the direction of the plant row, so that the frame 1 selects two adjacent crops, so that the two plants are located on both sides of the shell 2. Due to the intercropping method of cereals and beans, the two adjacent crops are different, which meets the monitoring requirements. Then, the support rods 3 are rotated respectively, and the threaded connection between the support rods 3 and the movable frame 4 is used to move the two movable frames 4 along the axial direction of the support rods 3, so that the excavation mechanism 5 on the movable frame 4 is aligned with the crop plants. The second oil cylinder 23 is turned on to drive the lifting seat 22 to descend along the column 21, so that the frame 1 is in contact with the ground. The excavation mechanism 5 is started to dig out the crop plants and the soil near the roots.

[0088] This structure can pre-determine the position of the crops to be excavated through the frame 1, and then adjust the position of the movable frame 4 through the action of the support rod 3, so that the two excavating mechanisms 5 can accurately excavate the crops at the same time, thereby improving efficiency.

[0089] like Figure 10 and Figure 11As shown, the excavation mechanism 5 includes: a bracket 51, a chute 52, a shovel plate 53 and a first oil cylinder 54. The bracket 51 is installed in the mobile frame 4. The bracket 51 is set as a regular polygon, which is a regular hexagon in this embodiment. It has six equal sides and six equal internal angles and has good stability. There are six chutes 52, which are respectively opened on the six sides of the bracket 51. The shovel plate 53 is slidably installed in the chute 52. The chute 52 and the shovel plate 53 are both inclined at 60 degrees, and each shovel plate 53 is set as an inverted triangle with a specific angle and shape to ensure that the six shovel plates 53 fit together to enclose a regular pyramid space, thereby ensuring that when digging crops, the space can fully support a crop and the soil near the crop roots, which is convenient for regular monitoring and detection work. The first oil cylinder 54 is installed on the bracket 51, and the output end of the first oil cylinder 54 is connected to the shovel plate 53. When the first oil cylinder 54 is turned on, each shovel plate 53 can move along the inclined direction of the slide 52. When the shovel plate 53 moves obliquely upward, each shovel plate 53 separates from each other, so that the middle space of the bracket 51 is opened.

[0090] When the above structure is in use, the shovel plates 53 are initially separated from each other, leaving the internal space of the bracket 51 open. When the bracket 51 is aligned with the crop to be excavated as the movable plate 4 moves, the second oil cylinder 23 is opened to lower the frame 1 as a whole, allowing the crop to pass through the middle space of the bracket 51 as a whole. Subsequently, the first oil cylinders 54 are opened in turn to allow the corresponding shovel plates 53 to be inserted into the soil along the chute 52 at an angle downward. When the shovel plates 53 contact and close with each other, the crop and the soil near the crop roots are completely separated, and then the frame 1 rises to complete the excavation work.

[0091] The mechanism is capable of completely excavating the soil of crops and crop roots and taking complete samples by setting up multiple shovel plates 53 that can be closed into a regular pyramid space, which can meet the needs of monitoring and detection work; the sharp part of the shovel plate 53 set in an inverted triangle shape can be quickly and smoothly inserted into the soil to improve the excavation efficiency; in addition, by starting the first oil cylinder 54 in sequence, each shovel plate 53 can be inserted into the soil in sequence, avoiding the joint force of each shovel plate 53 causing the entire equipment to overturn, while ensuring the stability of each shovel plate 53 to avoid mutual interference.

[0092] like Figure 1 and Figure 2As shown, the monitoring system for the underground growth status of intercropping of wheat and beans also includes: a mounting plate 19 and a placement groove 20. There are two mounting plates 19, which are respectively installed on the cart 12. The mounting plates 19 are located outside the rotation radius of the rotating seat 17 to avoid interference. The placement slot 20 is installed on the mounting plate 19; the internal space of the placement slot 20 is set in the shape of a regular hexagonal pyramid and is adapted to the space enclosed by the six shovel plates 53. The inner wall of the placement slot 20 is installed with the M272974 model soil temperature and humidity rapid tester probe and the Hanna HI98194 model soil nutrient probe. Among them, the M272974 model soil temperature and humidity rapid tester probe is a common equipment in this field, with a size of 20mm*50mm, a measurement accuracy of ±0.2℃ temperature, ±3% humidity, a temperature resolution of 0.1℃, and a humidity resolution of 0.1%. The probe can be used to measure the temperature and humidity of the soil placed in the placement slot 20, and then obtain relevant data; the Hanna HI98194 soil nutrient probe is also a common equipment in this field. It uses ion selective electrode ISE technology and can measure a variety of nutrient parameters in the soil, including ammonium nitrogen, nitrate nitrogen, potassium ions, etc.

[0093] When the above-mentioned equipment is in use, it is necessary to use the excavation mechanism 5 to dig the crops, and then start the second cylinder 23 to make the frame 1 rise as a whole, and then turn on the second motor 16 to drive the first gear 14 to rotate, and then make the second gear 15 drive the rotating seat 17 to rotate, so that the frame 1 is rotated as a whole to the side of the mounting plate 19, and adjust the two excavation mechanisms 5 to align with the top of the two placement grooves 20 respectively by rotating the support rod 3, and turn on the second cylinder 23 to make the excavation mechanism 5 fall into the placement groove 20, and then each first cylinder 54 drives each shovel plate 53 to separate from each other, and the crops and soil are placed in the placement groove 20, and the soil is tested with a probe, and the status of the plant root system is directly observed. After the detection is completed, the crop plants can be re-buried in the excavation pit for subsequent continuous monitoring.

[0094] After the frame 1 has framed two crops, it is inconvenient for the staff to manually adjust the positions of the two mobile racks 4. Therefore, the following solution is proposed to drive the two support rods 3 to rotate independently, so that the rotation of the support rods 3 can drive the mobile rack 4 to move. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the monitoring system for underground growth status of intercropping of grass and beans further comprises a driving unit for driving the support rod 3 to rotate, and the driving unit is installed in the housing 2. The driving unit comprises a control mechanism 6 and a linkage assembly.

[0095] The control mechanism 6 includes a first rotating drum 61, a first ratchet ring 62, a first ratchet tooth 63, a first bevel gear 64, a second ratchet ring 65, a second ratchet tooth 66, a second bevel gear 67, a second rotating drum 68, a protrusion 69, a limiting ring 610, a first mounting seat 611, a first spring 612, a first clamping block 613, a second mounting seat 614, a second spring 615, and a second clamping block 616. The second bevel gear 67 is rotatably mounted in the housing 2, and the second ratchet ring 65 is mounted on the second bevel gear 67. The two form an integral unit, capable of synchronous rotation and braking. There are a plurality of second ratchet teeth 66, equidistantly arranged along the circumference of the second ratchet ring 65. The first bevel gear 64 is rotatably mounted on the second ratchet ring 65, and the first ratchet ring 62 is mounted on the first bevel gear 64. The two form an integral unit, capable of synchronous rotation and braking. There are a plurality of first ratchet teeth 63, equidistantly arranged along the circumference of the first ratchet ring 62. The first rotating cylinder 61 is rotatably mounted in the outer shell 2. The first rotating cylinder 61 is located on the inner side of the first ratchet ring 62, the first bevel gear 64, the second ratchet ring 65 and the second bevel gear 67, and the above structures are coaxially arranged. The second rotating cylinder 68 is rotatably mounted in the first rotating cylinder 61 and is coaxially arranged with the first rotating cylinder 61. The first mounting seat 611 is mounted in the second rotating cylinder 68, and the relative position relationship between the first mounting seat 611 and the second rotating cylinder 68 remains unchanged. The first clamping block 613 is slidably mounted in the first mounting seat 611, and one end of the first clamping block 613 extends out of the outer wall of the second rotating cylinder 68 and the first rotating cylinder 61. The portion of the first clamping block 613 extending out of the outer wall of the second rotating cylinder 68 and the first rotating cylinder 61 is a right-angled trapezoid. The position of the first clamping block 613 corresponds to that of the first ratchet ring 62, as shown in FIG. Figure 8 As shown, when the second rotating drum 68 rotates clockwise, the straight edge of the first clamping block 613 and the straight edge of the first ratchet 63 can cooperate to rotate the first ratchet ring 62 and the first bevel gear 64. Conversely, when the second rotating drum 68 rotates counterclockwise, the first clamping block 613 will retract toward the first mounting seat 611 due to the oblique edge of the first ratchet 63 and the position limit of the first rotating drum 61, and will not be able to drive the first ratchet ring 62 to rotate. The first spring 612 is installed between the first clamping block 613 and the first mounting seat 611. When the first clamping block 613 is forced to move toward the first mounting seat 611, the first spring 612 is compressed. After the external force is removed, the first clamping block 613 can be reset due to the position limit of the first spring 612. The second mounting seat 614 is installed in the second rotating cylinder 68, and the second clamping block 616 is slidably installed in the second mounting seat 614. One end of the second clamping block 616 extends out of the outer wall of the second rotating cylinder 68 and the first rotating cylinder 61. The position of the second clamping block 616 corresponds to the position of the second ratchet ring 65. The second spring 615 is installed between the second clamping block 616 and the second mounting seat 614. Figure 9As shown, in this embodiment, the direction of the second ratchet teeth 66 is opposite to that of the first ratchet teeth 63. The shape of the second block 616 is the same as that of the first block 613, but with the inclined surface facing in the opposite direction. The second block 616 can independently drive the second ratchet ring 65 and the second bevel gear 67 to rotate counterclockwise as the second rotating drum 68 rotates, operating on the same principle as the first block 613 drives the first ratchet ring 62 to rotate. The first rotating drum 61 is provided with slots corresponding to the first block 613 and the second block 616. A protrusion 69 is mounted on the second rotating drum 68, and a retaining ring 610 is mounted on the inner wall of the first rotating drum 61. The retaining ring 610 is arranged in a C-shape, with the protrusion 69 located at the notch in the C-shape of the retaining ring 610. The two interact to limit the relative position variation range of the second rotating drum 68 within the first rotating drum 61. A first motor 7 is mounted on the housing 2. The output end of the first motor 7 extends into the housing 2 and is connected to the second rotating drum 68. Turning on the first motor 7 can drive the second rotating drum 68 to rotate. In this embodiment, the first motor 7 is a 68KTYZ model series motor, and its output end can be driven in both directions according to the control selection.

[0096] The linkage assembly includes: a mounting frame 8, a rotating rod 9, a third bevel gear 10, and a fourth bevel gear 11. The mounting frame 8 is mounted in the housing 2, and the rotating rod 9 is rotatably mounted on the mounting frame 8. The mounting frame 8 supports and fixes the rotating rod 9, ensuring the stability of the rotating rod 9 during rotation. There are two third bevel gears 10, one mounted at each end of the rotating rod 9. The fourth bevel gear 11 is mounted on the support rod 3, and the fourth bevel gear 11 meshes with one of the third bevel gears 10. In this embodiment, there are two sets of linkage assemblies, one mounted on either side of the control mechanism 6 in the housing 2. In the two sets of linkage assemblies, the third bevel gear 10, mounted on the end of the rotating rod 9 away from the fourth bevel gear 11, meshes with the first bevel gear 64 and the second bevel gear 67, respectively. This ensures that when the first bevel gear 64 rotates, it can drive one of the support rods 3 to rotate, and when the second bevel gear 67 rotates, it can drive the other support rod 3 to rotate.

[0097] During operation, the first motor 7 is turned on to drive the second rotating drum 68 clockwise. The first clamping block 613 extends from the slot on the outer wall of the first rotating drum 61 and engages with the first ratchet 63, driving the first bevel gear 64 to rotate clockwise. This in turn drives the meshed third bevel gear 10 and the rotating rod 9 to rotate, thereby rotating one of the support rods 3. During this process, the second clamping block 616 retracts into the second mounting seat 614. When the output end of the motor 7 rotates in the reverse direction, the first clamping block 613, restrained by the first rotating drum 61, retracts into the first rotating drum 61. Simultaneously, as the second rotating drum 68 rotates, the protrusion 69 rotates within the notch of the retaining ring 610. When the second clamping block 616 aligns with the slot on the first rotating drum 61, it extends due to the elastic force of the second spring 615. This, in conjunction with the second ratchet 66, drives the second ratchet ring 65 and the second bevel gear 67 counterclockwise, thereby rotating the other support rod 3.

[0098] By utilizing the above-mentioned mechanism, the forward and reverse rotation of the output end of the motor 7 can be utilized to drive the two support rods 3 to rotate independently, and the positions of the movable frame 4 and the two digging mechanisms 5 can be adjusted separately according to needs. It has high flexibility and can align the two crop plants very conveniently. Through the cooperation of the limit ring 610 and the protrusion 69, the relative displacement of the second rotating drum 68 and the first rotating drum 61 can be limited to avoid excessive rotation and ensure accuracy.

[0099] It is worth noting that in this embodiment, the first rotating drum 61 is installed in the housing 2 through a damping shaft. The damping shaft is a common component widely used in the fields of mechanical connection and motion control. It increases the resistance of the first rotating drum 61 during its rotation. Through this resistance, it is ensured that the first block 613 and the second block 616 can be smoothly retracted when they are retracted using the inclined surface: when the first block 613 or the second block 616 is retracted using the inclined surface, the force generated by the retraction action needs to overcome the resistance provided by the damping shaft if it is to drive the first rotating drum 61 to rotate. When in use, this resistance is set to be greater than the force generated when the first block 613 or the second block 616 is retracted using the inclined surface, which can ensure that the retraction force is insufficient to cause the first rotating drum 61 to rotate, thereby ensuring that the first block 613 and the second block 616 can be smoothly retracted, avoiding driving the first rotating drum 61 to rotate during retraction.

[0100] In addition, the housing 2 is provided with a toggle slot 201, which corresponds to the position of the first bevel gear 64 and the second bevel gear 67, ensuring that the first bevel gear 64 and the second bevel gear 67 are partially exposed. When the first clamping block 613 engages with the first ratchet 63 and the second clamping block 616 does not engage with the second ratchet 66, the second bevel gear 67 can be rotated in the opposite direction using a tool such as a wrench or manually. Similarly, when the first clamping block 613 does not engage with the first ratchet 63 and the second clamping block 616 engages with the second ratchet 66, the first bevel gear 64 can be rotated in the opposite direction, thereby ensuring that the two moving frames 4 and the two excavating mechanisms 5 return to their initial positions when excavation is completed, facilitating their next use.

[0101] The first and second cylinders 54 and 23 mentioned in this embodiment are both existing components. They are hydraulic actuators that convert hydraulic energy into mechanical energy to achieve linear reciprocating motion. The piston rods extend and retract using the movement of hydraulic oil. The oil tank and hydraulic oil pump supplying the first and second cylinders 54 and 23 are mounted at the center of the swivel base 17, ensuring stability while also increasing the weight of the core of the device, further enhancing stability.

[0102] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
