Description

Technical Field

[0001] This utility model relates to the field of vine support, and in particular to an adaptive support device for the growth of tomato vines. Background Technology

[0002] In the tomato cultivation industry, supporting tomato vines is a key agronomic operation. As tomato plants grow, the vines extend and thicken, requiring effective support devices to guide their growth direction, ensure ventilation and light penetration, and thus improve fruit yield and quality.

[0003] Currently, the traditional method of supporting tomato vines mainly uses fixed supports. While fixed supports provide some support, their structure is fixed and lacks flexibility. They cannot adapt to changes in the height, curvature, and thickness of the vines. During the vine growth process, rigid fixed supports can easily cause mechanical damage to the vines, affecting the normal growth of the plant. At the same time, fixed support methods may lead to poor ventilation and light penetration in certain areas, increasing the risk of pests and diseases.

[0004] Therefore, proposing a support device that can automatically adjust to changes in tomato vine growth is of great practical significance for improving the automation level of tomato cultivation, reducing labor intensity, and ensuring healthy plant growth. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adaptive support device for tomato vine growth, which aims to improve the problem that the existing technology has a fixed structure, lacks flexibility, and cannot adaptively adjust to changes in the height, curvature, and thickness of the vine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive support device for tomato vine growth, comprising two columns, a ground insertion rod fixed at the bottom of the columns, an inner cylinder block movably passing through the inner cavity of the columns, a support crossbar fixedly connected between the two inner cylinder blocks, a hydraulic rod installed in the inner cavity of the columns, a movable block fixed at the output end of the hydraulic rod, and a pressure sensor installed on the top surface of the movable block;

[0007] The surface of the support crossbar is movably connected to multiple support fixing components. The surface of the support fixing components is provided with contact adaptive components for supporting and fixing the tomato vines. The contact adaptive components include an airbag and a micro air pump, with the micro air pump connected to the airbag.

[0008] As a further description of the above technical solution:

[0009] The top of the column is open, and the inner cylinder block can move upward out of the inner cavity of the column;

[0010] As a further description of the above technical solution:

[0011] A through hole is provided on one side of the surface of the column, and the support crossbar is connected to the inner cylinder block inside the column through the through hole to limit the support crossbar when the height is adjusted.

[0012] As a further description of the above technical solution:

[0013] The inner cylinder block is located inside the column and at the top of the pressure sensor. The inner cylinder block applies pressure to the pressure sensor by bearing its own weight.

[0014] As a further description of the above technical solution:

[0015] The support fixing component includes a movable seat and a support rotating frame. The movable seat is movably connected to the surface of the support crossbar, and the support rotating frame is rotatably connected to the front side of the movable seat.

[0016] As a further description of the above technical solution:

[0017] The surface of the movable seat is provided with a slot for one end of the rotating frame to be inserted;

[0018] As a further description of the above technical solution:

[0019] The airbag is installed on the front side of the movable seat to accommodate tomato vines of different thicknesses and provide gentle support.

[0020] As a further description of the above technical solution:

[0021] The air pump is installed at the bottom of the movable seat and can adjust the air pressure inside the airbag to change the contact pressure between the airbag and the vine.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, as the tomato vines continue to grow and their height gradually increases, the weight of the vines and the pressure on the support crossbar also increase. The pressure sensor can keenly detect this pressure change and quickly feed the pressure signal back to the control system. The hydraulic rod works to push the movable block upward, which in turn drives the inner cylinder block and the support crossbar to rise. The support crossbar can always be kept at a suitable height, providing effective support for the tomato vines at different growth stages, ensuring that the vines can grow in the correct direction and avoid falling over due to lack of support, thereby improving the yield and quality of tomatoes.

[0024] 2. In this utility model, the airbag is installed on the front side of the movable seat, which can adapt to tomato vines of different thicknesses. When the vine comes into contact with the airbag, the airbag can deform according to the thickness of the vine, providing a gentle support force and avoiding damage to the vine. At the same time, the miniature air pump installed at the bottom of the movable seat can adjust the air pressure in the airbag. According to the different clamping force requirements of the tomato vine during its growth, the contact pressure between the airbag and the vine is changed, realizing adaptive adjustment of the clamping force and providing a more suitable growth environment for the tomato vine.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4This utility model provides an embodiment of an adaptive support device for tomato vine growth, comprising two columns 1, with a ground-inserting rod 2 fixed to the bottom of each column 1. An inner cylinder block 3 movably passes through the inner cavity of each column 1, and a support crossbar 4 is fixedly connected between the two inner cylinder blocks 3. A hydraulic rod 6 is installed inside the inner cavity of each column 1, and a movable block 7 is fixed to the output end of the hydraulic rod 6. A pressure sensor 8 is installed on the top surface of the movable block 7. Multiple support fixing parts 9 are movably connected to the surface of the support crossbar 4. Contact adaptive parts 10 are provided on the surface of the support fixing parts 9 for supporting and fixing the tomato vines. The contact adaptive parts 10 include an airbag 101 and a miniature air pump 102, with the miniature air pump 102 connected to the airbag 101. The ground-inserting rod 2 firmly inserts the device into the soil, increasing the contact area and friction between the device and the ground, allowing the column 1 to be more firmly rooted in the soil, enhancing the device's wind resistance and stability. The inner cylinder block 3 can move up and down within the column 1; this mobility allows the height of the support crossbar 4 to be adjusted according to the soil conditions. The system adjusts the height of the tomato vines according to their growth. As the vines grow taller, the inner cylinder block 3 moves upward, raising the support crossbar 4 to provide the appropriate support height for the vines and meet the support needs at different growth stages. When the pressure on the support crossbar 4 increases due to the vine growth, the movable block 7 moves upward under the action of the hydraulic rod 6, which in turn raises the inner cylinder block 3 and the support crossbar 4, achieving automatic height adjustment. This automatic adjustment mechanism reduces the workload of frequent manual adjustments and improves planting efficiency. The inner cylinder block 3 applies pressure to the pressure sensor 8 through its own weight. The pressure sensor 8 can sense the pressure changes transmitted by the inner cylinder block 3 in real time and convert the pressure signal into an electrical signal to feed back to the control system. The control system judges the growth status of the tomato vines based on the pressure signal, thereby controlling the operation of the hydraulic rod 6 to achieve precise adjustment of the height of the support crossbar 4. This intelligent sensing and adjustment mechanism ensures that the device can respond promptly to changes in the growth of the tomato vines and provide the most suitable support height for the vines.

[0033] Reference Figures 1-4The top of the column 1 is open, allowing the inner cylinder block 3 to move upwards out of the inner cavity of the column 1. A through hole 5 is provided on one side of the surface of the column 1, through which the supporting crossbar 4 is connected to the inner cylinder block 3 inside the column 1. This through hole 5 is used to limit the height of the supporting crossbar 4 during height adjustment. The inner cylinder block 3 is located in the inner cavity of the column 1 and is located on top of the pressure sensor 8. The inner cylinder block 3 applies pressure to the pressure sensor 8 by bearing its own weight. The open top of the column 1 allows the inner cylinder block 3 to be easily moved upwards out of the inner cavity of the column 1 when needed. During the assembly of the device, the operator can easily insert the inner cylinder block 3 into the inner cavity of the column 1 and connect it to the supporting crossbar 4. During the height adjustment of the supporting crossbar 4, the through hole 5 ensures that the supporting crossbar 4 can only move up and down in the vertical direction, preventing the supporting crossbar 4 from shifting or shaking during movement, thus improving the stability and reliability of the device.

[0034] Reference Figures 1-4 The support fixture 9 includes a movable seat 91 and a support rotating frame 92. The movable seat 91 is movably connected to the surface of the support crossbar 4, and the support rotating frame 92 is rotatably connected to the front side of the movable seat 91. The surface of the movable seat 91 has a slot 93 into which one end of the support rotating frame 92 can enter. An airbag 101 is installed on the front side of the movable seat 91 to adapt to tomato vines of different thicknesses and provide gentle support. An air pump 102 is installed at the bottom of the movable seat 91 and can adjust the air pressure inside the airbag 101 to change the contact pressure between the airbag 101 and the vine. The setting of multiple support fixtures 9 can be flexibly adjusted according to the growth number and distribution of tomato vines to ensure that each vine receives effective support. The movable seat 91 can move freely on the support crossbar 4, making it convenient for growers to adjust the position of the support fixtures 9 according to the position of the tomato vines, making the support more precise. When the support frame 92 is rotated to the appropriate position, one end can enter the slot 93, keeping the support frame 92 stable and preventing it from rotating arbitrarily due to external forces, thus ensuring the support effect on the tomato vines. When a thin tomato vine comes into contact with the airbag 101, the airbag 101 will deform and fit tightly against the surface of the vine, but will not apply excessive pressure to the vine, avoiding damage. For thick tomato vines, the airbag 101 can also adjust the degree of deformation according to the thickness of the vine, providing stable support. The gentle support force of the airbag 101 helps protect the tomato vines and promote their healthy growth. The micro air pump 102 can adjust the air pressure of the airbag 101 in a timely manner according to the actual situation, so that the airbag 101 always provides appropriate support force to the vines, meeting the needs of different growth stages of tomatoes. This dynamic adjustment mechanism improves the adaptability and intelligence level of the device and reduces the frequency of manual intervention.

[0035] Working principle: The ground stakes 2 at the bottom of the two uprights 1 are inserted into the soil of the tomato planting area to ensure that the uprights 1 are stable and upright, providing a stable support foundation for the entire device. Based on the initial height of the tomato seedlings, the initial height of the support crossbar 4 is set so that the support crossbar 4 is in a position suitable for the tomato seedlings to climb and support. As the tomato vines grow, their weight gradually increases, which will exert downward pressure on the support crossbar 4. This pressure is transmitted to the pressure sensor 8 on the top surface of the movable block 7 through the inner cylinder block 3. The pressure sensor 8 senses the pressure change in real time and transmits the pressure signal to the control system. If the control system determines that the height of the support crossbar 4 needs to be adjusted, it will send a command to the hydraulic rod 6. After receiving the command, the hydraulic rod 6 starts to work, and its output end extends upward, pushing the movable block 7 to move upward. Since the inner cylinder block 3 is located above the movable block 7 and is pushed by it, the inner cylinder block 3 will also move upward, thereby driving the support crossbar 4, which is fixedly connected to it, to rise. During the upward process of the support crossbar 4, the support crossbar 4 is limited and guided by the through hole 5 on one side of the surface of the uprights 1, ensuring that the support crossbar 4 can only rise smoothly in the vertical direction.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
