[0002] Grain-bean intercropping refers to planting gramineous crops and legumes on the same plot of land at the same time, taking advantage of the deep rooting ability of gramineous crops to increase soil organic matter content and maintain soil moisture; and taking advantage of the fact that legumes can obtain nitrogen from the air through rhizobia to reduce nitrogen loss in the land. With the continuous development of agricultural technology, intercropping has been more and more widely used in agricultural production. Grain-bean intercropping is a common intercropping pattern, which can make full use of land resources and improve crop yield and quality.

[0003] At present, monitoring of the underground growth status of intercropped crops of 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 operation processes together form a complete monitoring system.

[0004] The current monitoring system for the underground growth status of intercropping of grass and beans usually requires digging up the target plants separately in two batches.

DETAILED DESCRIPTION

[0081] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0082] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0083] like Figure 1 , Figure 2 , Figure 3 and Fig.12 As shown, the monitoring system for the underground growth state of intercropping of wheat and beans comprises: a cart 12, a roller 121 is installed at the bottom of the cart 12, and a push rod 122 is also installed on the cart 12. When in use, the push rod 122 is held by hand to push the cart 12, so that the device can be moved as a whole. It also comprises: a mounting seat 13, a first gear 14, a second gear 15, a second motor 16, a rotating seat 17, a counterweight 18, a stand 21, a lifting seat 22 and a second oil cylinder 23. The mounting seat 13 is mounted on the upper surface of the cart 12, and the mounting seat 13 is a hollow structure. The first gear 14 is rotatably mounted in the mounting seat 13, and the second gear 15 is rotatably mounted in the mounting seat 13. The second gear 15 is meshed and connected with the first gear 14. 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, and at the same time, it can increase the torque, reduce the rotation speed, and improve the stability. The second motor 16 is mounted on the cart 12. The output end of the second motor 16 extends into the mounting seat 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 seat 17 is mounted on the mounting seat 13 and is connected to the second gear 15. The rotation of the second gear 15 can drive the rotating seat 17 to rotate synchronously. The counterweight 18 is mounted on the rotating seat 17 on the side away from the housing 2. The counterweight 18 is used to balance the weight at both ends of the rotating seat 17 to prevent the overall overturning of the equipment. The stand 21 is mounted on the cart 12, and is located on the side away from the counterweight 18. The lifting seat 22 is slidably mounted on the stand 21. The second oil cylinder 23 is mounted on the stand 21, and the output end of the second oil cylinder 23 is connected to the lifting seat 22. Turning on the second oil cylinder 23 can drive the lifting seat 22 to move along the axial direction of the stand 21.

[0084] like Figure 1 , Figure 2 and Figure 3 As shown, the monitoring system for the underground growth state of intercropping of wheat and beans also includes: a frame 1, a shell 2, a support rod 3, a mobile frame 4 and an excavation mechanism 5, and 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 stand 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 a square shape, and the middle part is open. The frame 1 is used to frame the crops to be excavated. The shell 2 is used as a boundary, and two crops to be excavated are respectively located in the space on both sides of the shell 2 on the inner side of the frame 1. The number of support rods 3 is two, and they are respectively symmetrically rotated and installed on the frame 1, and the support rods 3 pass through the shell 2. There are two mobile frames 4, which are respectively installed on the support rods 3, and the two mobile frames 4 are respectively located on both sides of the shell 2. In this embodiment, the two support rods 3 are provided with threads, and the two support rods 3 are symmetrical to each other, so that the threaded parts on the two support rods 3 correspond to each other, and the two mobile frames 4 are respectively threadedly connected with the threaded part of one of the support rods 3, and are slidably connected with the other support rod 3 without the threaded part. When one of the support rods 3 is controlled to rotate, one of the mobile frames 4 can be driven to move along the axial direction of the support rod 3, and the mobile frame 4 is kept stable by the limit of the other support rod 3. The digging mechanism 5 is installed on the mobile frame 4. The digging mechanism 5 is used to dig the selected crop plants.

[0085] When the above structure is in use, the cart 12 is pushed to move along the direction of the whole row of plants, 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 needs. Then the support rods 3 are rotated respectively, and the threaded connection between the support rods 3 and the mobile frame 4 is used to move the two mobile frames 4 along the axial direction of the support rods 3 respectively, so that the excavation mechanism 5 on the mobile 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, and the excavation mechanism 5 is started to dig out the crop plants and the soil near the root system.

[0086] This structure can predetermine the position of the crop to be excavated through the frame 1, and then adjust the position of the movable frame 4 through the support rod 3, so that the two excavation mechanisms 5 can accurately excavate the crop at the same time, thereby improving efficiency.

[0087] like Fig.10 and Fig.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. In this embodiment, it is a regular hexagon, which 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 root system of the crop, 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. Turning on the first oil cylinder 54 can make each shovel plate 53 move along the inclined direction of the slide groove 52 respectively. 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 open.

[0088] When the above structure is in use, in the initial state, the shovel plates 53 are separated from each other, so that the internal space of the bracket 51 is 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, so that the crop passes through the middle space of the bracket 51 as a whole. Then, the first oil cylinders 54 are opened in turn to make the corresponding shovel plates 53 tilt downward along the slide groove 52 and insert into the soil. When the shovel plates 53 contact and close with each other, the crop and the soil near the root system of the crop are completely separated, and then the frame 1 rises to complete the excavation work.

[0089] The mechanism can completely excavate the soil of crops and crop roots and take complete samples by setting up multiple shovel plates 53 that can be closed into a regular pyramid space, which can meet the 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 to cause the entire equipment to tip over, while ensuring that each shovel plate 53 is stable to avoid mutual interference.

[0090] like Figure 1 and Figure 2As shown, the monitoring system for 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 mounted 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 soil temperature and humidity rapid measuring instrument probe and the Hanna HI98194 soil nutrient probe. Among them, the M272974 soil temperature and humidity rapid measuring instrument 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 adopts ion selective electrode ISE technology and can measure a variety of nutrient parameters in the soil, including ammonium nitrogen, nitrate nitrogen, potassium ions, etc.

[0091] When the above-mentioned equipment is in use, it is necessary to use the excavation mechanism 5 to excavate the crops, and then start the second cylinder 23 to make the frame 1 rise as a whole, and then start 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 tops of the two placement grooves 20 respectively by rotating the support rod 3, and start 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 detected by using a probe, and the state of the plant root system is directly observed. After the detection is completed, the crop plants can be reburied in the excavation pit to facilitate subsequent continuous monitoring work.

[0092] After the frame 1 has framed two crops, it is inconvenient for the staff to manually adjust the positions of the two moving frames 4, so 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 moving frames 4 to move. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the monitoring system for underground growth status of intercropping of grass and beans also includes a driving unit for driving the support rod 3 to rotate, and the driving unit is installed in the housing 2. The driving unit includes a control mechanism 6 and a linkage assembly.

[0093] The control mechanism 6 includes: a first rotating cylinder 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 cylinder 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 a whole and can be synchronously rotated and braked. There are a plurality of second ratchet teeth 66, which are equidistantly arranged on the second ratchet ring 65 along the circumferential direction. 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 a whole and can be synchronously rotated and braked. There are a plurality of first ratchet teeth 63, which are equidistantly arranged on the first ratchet ring 62 along the circumferential direction. The first rotating cylinder 61 is rotatably mounted in the outer shell 2. The first rotating cylinder 61 is located on the inner sides 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 installed 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 walls 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 walls 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, the second rotating cylinder 68 rotates clockwise, and the first ratchet ring 62 and the first bevel gear 64 can be rotated by utilizing the cooperation of the straight edge of the first clamping block 613 and the straight edge of the first ratchet 63. On the contrary, the second rotating cylinder 68 rotates counterclockwise, and the first clamping block 613 shrinks toward the first mounting seat 611 by utilizing the bevel edge of the first ratchet 63 and the limit of the first rotating cylinder 61, and the first ratchet ring 62 cannot be driven to rotate. The first spring 612 is installed between the first clamping block 613 and the first mounting seat 611. The first clamping block 613 is forced to move toward the first mounting seat 611 to compress the first spring 612. After the external force is removed, the first clamping block 613 can be reset by utilizing the 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, and 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. Fig. 9As shown, in this embodiment, the direction of the second ratchet 66 is opposite to that of the first ratchet 63, and the shape of the second block 616 is the same as that of the first block 613, but the inclined surface faces in the opposite direction. The second block 616 can drive the second ratchet ring 65 and the second bevel gear 67 to rotate counterclockwise as the second rotating cylinder 68 rotates, and its principle is the same as the principle of the first block 613 driving the first ratchet ring 62 to rotate. The first rotating cylinder 61 is provided with slots corresponding to the first block 613 and the second block 616. The protrusion 69 is installed on the second rotating cylinder 68, and the limit ring 610 is installed on the inner wall of the first rotating cylinder 61. The limit ring 610 is arranged in a C shape, and the protrusion 69 is located at the notch position of the C shape of the limit ring 610. The two cooperate with each other to limit the relative position change range of the second rotating cylinder 68 rotating in the first rotating cylinder 61. A first motor 7 is installed 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 uses a 68KTYZ model series motor, and its output end can be driven in both directions according to the control selection.

[0094] 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 installed in the housing 2, and the rotating rod 9 is rotatably installed on the mounting frame 8. The mounting frame 8 plays the role of supporting and fixing the rotating rod 9 to ensure the stability of the rotating rod 9 during the rotation process. There are two third bevel gears 10, which are respectively installed at both ends of the rotating rod 9. The fourth bevel gear 11 is installed on the support rod 3, and the fourth bevel gear 11 is meshed with one of the third bevel gears 10. In this embodiment, there are two groups of linkage assemblies, which are respectively installed on both sides of the control mechanism 6 in the housing 2. In the two groups of linkage assemblies, the third bevel gear 10 installed on the end of the rotating rod 9 away from the fourth bevel gear 11 is meshed and connected with the first bevel gear 64 and the second bevel gear 67 respectively. Thereby ensuring 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.

[0095] When the above structure is in use, the first motor 7 is turned on to drive the second rotating drum 68 to rotate clockwise, and the first clamping block 613 extends from the slot on the outer wall of the first rotating drum 61, cooperates with the first ratchet 63, drives the first bevel gear 64 to rotate clockwise, and then drives the third bevel gear 10 and the rotating rod 9 meshed therewith to rotate, and then rotates one of the supporting rods 3. In this process, the second clamping block 616 is retracted into the second mounting seat 614. When the output end of the motor 7 rotates in the reverse direction, the first clamping block 613 is limited by the first rotating drum 61 and retracted into the first rotating drum 61. At the same time, as the second rotating drum 68 rotates itself, the protrusion 69 rotates within the notch range of the limiting ring 610. When the second clamping block 616 corresponds to the slot on the first rotating drum 61, it is extended by the elastic force of the second spring 615, and cooperates with the second ratchet 66 to drive the second ratchet ring 65 and the second bevel gear 67 to rotate counterclockwise, and then drives the other supporting rod 3 to rotate.

[0096] By utilizing the above 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 according to needs. It has high flexibility and can align 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.

[0097] 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 field 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 retract using the inclined surface: when the first block 613 or the second block 616 retracts using the inclined surface, if the force generated by the retraction action is to drive the first rotating drum 61 to rotate, it is necessary to overcome the resistance provided by the damping shaft. When in use, this resistance is set to be greater than the force generated when the first block 613 or the second block 616 retracts 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, and avoiding driving the first rotating drum 61 to rotate during retraction.

[0098] In addition, the housing 2 is provided with a toggle groove 201, which corresponds to the position of the first bevel gear 64 and the second bevel gear 67, so that the first bevel gear 64 and the second bevel gear 67 are partially exposed. When the first clamping block 613 is matched with the first ratchet 63, and the second clamping block 616 is not matched with the second ratchet 66, the second bevel gear 67 can be rotated in the opposite direction by hand using a tool such as a wrench lever; similarly, when the first clamping block 613 is not matched with the first ratchet 63, and the second clamping block 616 is matched with the second ratchet 66, the first bevel gear 64 can be rotated in the opposite direction, so as to ensure that the two moving frames 4 and the two excavating mechanisms 5 return to the initial position when the excavation is finished, so as to facilitate the next use.

[0099] The first oil cylinder 54 and the second oil cylinder 23 mentioned in this embodiment are both existing equipment, which are hydraulic actuators that convert hydraulic energy into mechanical energy to achieve linear reciprocating motion, and use the movement of hydraulic oil to complete the extension and retraction of the piston rod. The oil tank and hydraulic oil pump that provide hydraulic oil for the first oil cylinder 54 and the second oil cylinder 23 in this embodiment are installed at the center of the rotating seat 17, ensuring stability while increasing the weight of the core position of the entire equipment, further increasing stability.

[0100] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
