Description

Technical Field

[0001] This invention relates to the field of crop growth monitoring technology, and in particular to a crop growth monitoring device. Background Technology

[0002] Crop growth monitoring technology provides agricultural users with information for assessing crop relationships and making decisions. Current crop growth information collection technologies can be broadly categorized into field surveys, sensor technology, and remote sensing. Traditional field surveys rely on manual observation. Sensor technology involves developing contact sensors adapted to specific crops or crops with similar growth characteristics. Remote sensing technology uses various bands of the electromagnetic spectrum, including visible light, infrared, and microwaves, to capture characteristic information of target crops in a non-contact manner. However, these methods have drawbacks: manual observation is labor-intensive, and measurements are subject to human error each time. Contact sensor technology requires electronic components, which are costly, and damaged electronic data is difficult to recover. Remote sensing technology is also costly and typically used for estimating crop conditions in a given area, making it unsuitable for detailed growth monitoring of individual crops. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a crop growth monitoring device to solve the problems of high manual monitoring intensity, large error, and high sensor detection cost in existing crop growth monitoring methods. The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a crop growth monitoring device, comprising a monitoring wrapping tube for wrapping crop stems, the monitoring wrapping tube comprising two symmetrically arranged semi-circular ring tubes, the two semi-circular ring tubes being detachably connected by a locking member, the semi-circular ring tube having a medium storage cavity for containing liquid medium, the semi-circular ring tube comprising an outer side wall, an inner side wall, an upper side wall and a lower side wall, the outer side wall being made of a rigid material, the inner side wall, the upper side wall and the lower side wall being made of a flexible material, the upper side wall being provided with a medium filling tube and a medium discharge tube, both of the medium filling tube and the medium discharge tube being connected to the medium storage cavity, the medium filling tube being provided with a sealing cap, and a plurality of flexible plates being spaced apart between the inner side wall and the outer side wall, the upper end of the flexible plates not contacting the upper side wall; It also includes a volume measuring tube with graduation lines. One end of the volume measuring tube has an opening, and the other end is connected to the medium discharge tube through a medium conveying tube. A rubber piston is installed inside the medium conveying tube, and a medium check valve is installed inside the medium conveying tube. The medium check valve is used to control the flow direction of the medium in the medium conveying tube so that it can only flow from the medium conveying tube to the volume measuring tube.

[0004] As a preferred embodiment, the semicircular annular tube is provided with connecting parts on both sides, and the two opposite connecting parts are connected by a locking member.

[0005] As a preferred embodiment, the locking component includes a locking bolt, and the connecting part is provided with a mounting hole that mates with the locking bolt.

[0006] As a preferred embodiment, the two connecting parts are provided with grooves on opposite sides, and the two opposite grooves are provided with first magnets, which are magnetically connected.

[0007] As a preferred embodiment, the medium filling tube is threadedly connected to the sealing cap.

[0008] As a preferred embodiment, the medium conveying pipe is U-shaped and includes a horizontal section. The two ends of the horizontal section are respectively vertically connected to a first vertical section and a second vertical section. The second vertical section has a groove that mates with a one-way valve for the medium. The first vertical section is threadedly engaged with a medium discharge pipe. The outer side of the medium discharge pipe has a first external thread. The first vertical section has a first internal thread that mates with the first external thread. The upper end of the volume measuring pipe has a medium inlet pipe that communicates with its interior. The second vertical section is threadedly engaged with the medium inlet pipe. The outer side of the medium inlet pipe has a second external thread. The second vertical section has a second internal thread that mates with the second external thread.

[0009] As a preferred embodiment, the outer wall is made of a transparent rigid material, the volume measuring tube is made of a transparent material, and the flexible plate is made of a flexible material.

[0010] As a preferred embodiment, the one-way medium valve includes a retaining ring and a one-way medium flow pipe passing through the retaining ring. The retaining ring engages with a retaining groove. The one-way medium flow pipe is made of a flexible material. A medium channel for liquid medium flow is provided in the middle of the one-way medium flow pipe. Two second magnets are arranged opposite each other in the vertical direction on the inner side of the medium channel. The two second magnets can attract each other to close the medium channel. A one-way medium flow port is provided at the end of the one-way medium flow pipe away from the retaining ring. Two third magnets are arranged opposite each other in the vertical direction on the inner side of the one-way medium flow port. The two third magnets can attract each other to close the one-way medium flow port. A counterflow medium sealing inlet is provided at the end of the one-way medium flow pipe away from the retaining ring and on the upper and lower sides of the one-way medium flow port.

[0011] As a preferred embodiment, the cross-section of the unidirectional medium flow pipe is rectangular.

[0012] The beneficial effects of this application are as follows: 1. This application sets up a monitoring wrapping tube for wrapping crop stems. The monitoring wrapping tube consists of two symmetrically arranged semi-circular ring tubes. The semi-circular ring tubes have a medium storage cavity for containing liquid medium. When the crop grows and squeezes the medium storage cavity, the liquid medium is discharged through the medium delivery tube to the volume measurement tube to indicate the change in crop growth volume. It adopts a purely mechanical structure, without the need for electronic components, thus avoiding data loss due to damage to electronic equipment.

[0013] 2. When the liquid medium of this application flows into the volume measuring tube, the rubber piston inside moves downward under the pressure of the liquid medium. The distance it moves can be read through the scale line, which is the crop growth volume measured by the device of this invention. An opening is provided at the bottom of the volume measuring tube to ensure that the lower part of the volume measuring tube will not generate pressure due to the downward movement of the rubber piston, thus ensuring the accuracy of the measurement.

[0014] 3. Medium one-way valve, used to control the flow direction of medium. It has a medium one-way flow pipe made of flexible material, so that the medium can only flow from the semi-circular pipe through the medium delivery pipe and then from the medium one-way flow port to the volume measuring pipe. It cannot flow in reverse, to avoid the liquid medium backflow phenomenon that may be caused by the pressure of the measuring pipe due to uncertain factors (such as animal impact, mud and rocks).

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Please see Figure 1-6This invention provides a crop growth monitoring device, including a monitoring wrapping tube 1 for wrapping crop stems. The monitoring wrapping tube 1 includes two symmetrically arranged semi-circular ring tubes 2, which are detachably connected by a locking member. Each semi-circular ring tube 2 has a medium storage cavity 21 for containing liquid medium. Each semi-circular ring tube 2 includes an outer side wall, an inner side wall 22, an upper side wall, and a lower side wall. The outer side wall is made of a rigid material, while the inner side wall 22, the upper side wall, and the lower side wall are all made of flexible materials. The upper side wall is provided with a medium filling tube 11 and a medium discharge tube 12. All are connected to the medium storage chamber 21. The medium filling tube 11 is equipped with a sealing cap 3. Multiple flexible plates 23 are spaced between the inner side wall 22 and the outer side wall. The upper end of the flexible plate 23 does not contact the upper side wall. It also includes a volume measuring tube 5. The volume measuring tube 5 is equipped with a scale line 6. One end of the volume measuring tube 5 is equipped with an opening 8. The other end is connected to the medium discharge tube 12 through the medium conveying tube 4. The medium conveying tube 4 is equipped with a rubber piston 7 and a medium one-way valve 13. The medium one-way valve 13 is used to control the flow direction of the medium in the medium conveying tube 4 so that it can only flow from the medium conveying tube 4 to the volume measuring tube 5.

[0024] The volume measuring tube 5 consists of two tubes. When the liquid medium flows into the volume measuring tube 5, the rubber piston 7 inside moves downward under the pressure of the liquid medium. The distance it moves can be read through the scale line 6, which is the crop growth volume measured by the device of the present invention. The lower part of the volume measuring tube 5 is provided with an opening to ensure that the lower part of the volume measuring tube will not generate pressure due to the downward movement of the rubber piston 7, thus ensuring the accuracy of the measurement.

[0025] The semicircular annular tube 2 has connecting parts on both sides, and the two opposite connecting parts are connected by a locking device. The semicircular annular tube 2 and the connecting parts are integrally formed, and the connecting parts are made of a rigid transparent material. The rigid transparent material can be glass. In this application, the flexible material can be made of rubber. The locking device includes a locking bolt 10, and the connecting part has a mounting hole 25 that mates with the locking bolt 10. The two opposite sides of the two connecting parts are respectively provided with grooves 24, and the two opposite grooves 24 are respectively provided with first magnets 9, and the two opposite first magnets 9 are magnetically connected. The medium filling tube 11 is threadedly connected to the sealing cap 3. The locking bolt 10 is also provided with a locking nut that mates with its thread.

[0026] In addition, the two semi-circular tubes 2 in this application are connected by locking bolts 10. This solution is suitable for crops with slower growth rates that can withstand the weight of the device of this invention. The second solution is to fix the connection by installing the first magnet 9 at the groove 24 of the connection part. This solution is suitable for crops with faster growth rates and avoids the bolt connection from interfering with crop growth.

[0027] Specifically, the medium delivery pipe 4 is U-shaped and includes a horizontal section. The two ends of the horizontal section are vertically connected to a first vertical section and a second vertical section, respectively. The second vertical section has a groove 15 that mates with the medium check valve 13. The first vertical section is threadedly engaged with the medium discharge pipe 12. The outer side of the medium discharge pipe 12 has a first external thread, and the first vertical section has a first internal thread 16 that mates with the first external thread. The upper end of the volume measuring pipe 5 has a medium inlet pipe 14 communicating with its interior. The second vertical section is threadedly engaged with the medium inlet pipe 14. The outer side of the medium inlet pipe 14 has a second external thread, and the second vertical section has a second internal thread 17 that mates with the second external thread. The outer wall is made of a transparent rigid material, the volume measuring pipe 5 is made of a transparent material, and the flexible plate 23 is made of a flexible material. One end of the volume measuring pipe 5 is closed, and the other end has an opening 8. The medium inlet pipe 14 is located at the closed end. In this embodiment, the opening 8 is at the lower end of the volume measuring pipe 5.

[0028] Furthermore, the one-way valve 13 includes a retaining ring 18 and a one-way flow tube 19 passing through the retaining ring 18. The retaining ring 18 engages with a retaining groove 15. The one-way flow tube 19 is made of a flexible material and has a medium channel 31 for liquid medium flow in the middle. Two second magnets 26 are vertically aligned on the inner side of the medium channel 31 and can attract each other to close the medium channel 31. A one-way flow port 20 is provided at the end of the one-way flow tube 19 away from the retaining ring 18. Two magnets 26 are vertically aligned on the inner side of the one-way flow port 20. The third magnet 29, and the two third magnets 29 can attract each other to close the one-way flow port 20 of the medium. The one-way flow pipe 19 is located at the end away from the retaining ring 18 and on the upper and lower sides of the one-way flow port 20, respectively, with a counterflow medium sealing inlet 28. The one-way flow pipe 19 is inclined and has a counterflow channel 30 communicating with the counterflow medium sealing inlet 28. The angle between the counterflow channel 30 and the medium channel 31 is an acute angle. The one-way flow pipe 19 is provided with a counterflow medium sealing outlet 27 communicating with the counterflow channel 30. The two counterflow medium sealing outlets 27 are located on the upper and lower end faces of the one-way flow pipe 19. The cross-section of the one-way flow pipe 19 is rectangular.

[0029] After the monitoring package tube 1 is fixed to the crop stem, the medium is delivered into the medium storage cavity of the semi-circular ring tube 2 through the medium filling tube 11. This medium can be a gas or a light liquid. After the medium is full, the semi-circular ring tube 2 is sealed with a sealing cap 3. To ensure measurement accuracy, the medium delivery tube 4 is filled with liquid medium when the medium is full. The rubber piston 7 is brought into contact with the inner wall of the closed end of the volume measuring tube 5. Multiple flexible plates 23 divide the medium storage cavity 21 into multiple receiving cavities. The medium storage cavity 21 and the upper part of the flexible plates 23 do not contact each other within the monitoring package, forming a connecting space between the medium storage cavity 21 and the upper part of the flexible plates 23. This connecting space ensures that the receiving cavities are in a connected state. This structure, with both spacing and interconnection, ensures the stability of the medium within the medium storage cavity 21 of the device and also ensures that the medium can be completely filled and discharged through the connecting space, increasing portability.

[0030] The semi-circular annular tube 2 and the volume measuring tube 5 are connected via a media delivery tube 4. When the crop stem grows, it compresses the inner side of the semi-circular annular tube 2. Since the inner side of the semi-circular annular tube 2 and the flexible plate 23 are made of flexible material, the space of the media storage cavity 21 will decrease. The media will flow into the volume measuring tube 5 through the media delivery tube 4. When there is media input in the space between the upper part of the volume measuring tube 5 and the rubber piston 7, the rubber piston 7 will move downward. The distance it moves downward can be read through the scale line 6. The change in volume is calculated as the volume of crop stem growth. An opening 8 is provided at the lower part of the volume measuring tube 5 to ensure that the space below the rubber piston 7 of the volume measuring tube 5 will not generate pressure when compressed, ensuring the effectiveness of the space change of the upper part of the rubber piston 7 of the volume measuring tube 5. The outer side of the monitoring wrapping tube 1 is made of a rigid transparent material, which can ensure the stability of the overall structure of the invention and reduce interference with crop growth.

[0031] The groove 15 at the end of the second internal thread 17 is used to connect and fix the one-way valve 13, specifically by fixing it through the gap between the retaining ring 18 and the groove 15 and the second internal thread 17. When crop volume measurement is performed, the medium flow direction can only be from right to left. When the volume measuring tube 5 is squeezed, the medium flow will flow from the counterflow medium closed inlet 28 through the counterflow channel 30 and out of the counterflow medium closed outlet 27. The counterflow channel 30 is arranged obliquely, so that when the medium flows through its interior, it generates pressure on the one-way flow port 20 and the medium channel 31. The two second magnets 26 and the two third magnets 29 attract each other to ensure that the one-way flow port 20 and the medium channel 31 are in a closed state, effectively preventing liquid backflow.

[0032] It should be noted that the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
