Description

Technical Field

[0001] This utility model relates to the field of crop vine training technology, and in particular to a ring belt tensioning adjustment device for crop vine training devices. Background Technology

[0002] When cultivating vine crops, such as cucumbers, loofahs, and cherry tomatoes in greenhouses, it's necessary to tie ropes around the vines to control their height. This rope control facilitates management. Because the entire growth cycle of these crops is long, the vine height needs to be adjusted multiple times during the trellising period. This requires repeatedly lowering the vines to facilitate manual tasks such as flower picking, thinning, and pruning. Traditionally, this involves manually removing the vines from the ropes multiple times, lowering them, and then re-trellising them – a labor-intensive and time-consuming process. Since the vines are generally long, repeated lowering can easily cause them to break, affecting yield. Furthermore, manual lowering requires manually removing and reinstalling the ropes, a physically demanding and inefficient process.

[0003] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a ring belt tensioning adjustment device for crop vine lowering devices. This device is reusable, shortens the time required for vine lowering, improves vine lowering efficiency, and can meet the needs of different crops, thus expanding the applicability of the device.

[0005] To achieve the above objectives, this utility model provides a ring belt tensioning adjustment device for crop vine lowering devices, comprising: a fixed plate installed on the top of a greenhouse, with side adjustment plates rotatably connected to both ends of the fixed plate, and guide support wheels rotatably provided on each side adjustment plate; a main hanging shaft and a drive shaft rotatably connected between the fixed plates, with several hanging ropes connected to the main hanging shaft, and a ring belt cooperating with the guide support wheels below the main hanging shaft, with hanging rope hooks cooperating with the hanging ropes on the ring belt; an adjusting component and a tensioning component threadedly connected to the drive shaft, with driven components slidably provided on the fixed plates on both sides of the drive shaft, with adjusting connecting rods rotatably provided between adjacent adjusting components and driven components, and driven connecting rods rotatably provided between adjacent driven components and side adjustment plates; and a tensioning support wheel cooperating with the ring belt below the tensioning component.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] See Figures 1-3 This utility model provides a ring belt tensioning adjustment device for crop vine training devices, comprising:

[0021] Fixed plate 1, two fixed plates 1 are arranged opposite each other and fixed (or detachable) installed on the top of the greenhouse. Side adjustment plates 2 are rotatably connected to both ends of the fixed plate 1. The side adjustment plates 2 can rotate with the connection point between them and the fixed plate 1 as the center. The bottom of the side adjustment plate 2 away from the fixed plate 1 is rotatably connected to a guide support wheel 5. An annular belt 6 is provided below the fixed plate 1. The annular belt 6 cooperates with four guide support wheels 5.

[0022] The main hanging shaft 3 of the hanging rope has two fixed plates 1 rotatably connected to its two ends. Several hanging rope rings 4 are fixedly connected to the surface of the main hanging shaft 3, and several hanging rope guide rings 7 are fixedly connected to the surface of the annular belt 6. Several hanging ropes are connected to the main hanging shaft 3. One end of the hanging rope is connected to the hanging rope ring 4, and the other end of the hanging rope passes through the hanging rope guide ring 7 and extends to the bottom of the greenhouse. The hanging ropes can be used to connect the vines of crops. The fixed plate 1 is equipped with a drive mechanism to control the rotation of the main hanging shaft 3 of the hanging rope. When the main hanging shaft 3 of the hanging rope rotates, the extension length of the hanging rope can be adjusted.

[0023] The drive shaft 9 is rotatably located below the main hanging shaft 3 of the suspension rope. Two fixed plates 1 are rotatably connected to both ends of the drive shaft 9. Two adjusting members 10 are threadedly connected to the drive shaft 9 located between the two fixed plates 1. When the drive shaft 9 rotates, the two adjusting members 10 move in opposite directions. A driven member 12 is slidably connected to the fixed plates 1 on both sides of the drive shaft 9. An adjusting rod 11 is rotatably connected between adjacent adjusting members 10 and driven members 12 (i.e., one end of the adjusting rod 11 is rotatably connected to the adjusting member 10, and the other end of the adjusting rod 11 is rotatably connected to the driven member 12). A driven rod 13 is rotatably connected between adjacent driven members 12 and the side adjusting plate 2 (i.e., one end of the driven rod 13 is rotatably connected to the driven member 12, and the other end of the driven rod 13 is rotatably connected to the side adjusting plate 2).

[0024] In addition, tensioning members 14 are threadedly connected to the drive shafts 9 on the opposite sides of the two fixed plates 1. The adjusting members 10 located at the same end of the drive shaft 9 move in the opposite direction to the tensioning members 14. Horizontal extension plates are fixedly connected to the tensioning members 14. Tensioning sliders 16 are slidably connected to the bottom surface of the extension plates. Tensioning support wheels 16 are rotatably connected to the bottom surface of the tensioning sliders 16. The tensioning support wheels 16 can cooperate with the annular belt 6. Springs are provided between adjacent tensioning sliders 16 and tensioning members 14. The springs are always in a compressed state.

[0025] The drive component 17 is fixedly mounted on one of the fixed plates 1, and a belt connects the output shaft of the drive component 17 to the drive shaft 9.

[0026] See Figures 1-3 Preferably, the fixing plate 1 at the connection between the side adjustment plate 2 and the fixing plate 1 is provided with fixing bolts 8, which can fix the side adjustment plate 2.

[0027] See Figures 1-3 Preferably, each of the fixed plates 1 is fixedly connected with a limiting rod that passes through the tensioner 14, which can prevent the tensioner 14 from rotating and ensure smooth operation of the device.

[0028] See Figures 1-3 Preferably, the drive unit 17 is a rotary motor that can provide sufficient power.

[0029] In the implementation of this utility model: the user connects one end of the hanging rope to the hanging rope ring 4, and the other end of the hanging rope passes through the hanging rope guide ring 7 and connects to the vine of the crop. When it is necessary to adjust the height of the vine, the drive mechanism drives the main hanging shaft 3 of the hanging rope to rotate, thereby adjusting the extension length of the hanging rope. When it is necessary to adjust the angle of the side adjustment plate 2, the fixing bolt 8 is removed first, and then the drive component 17 is started. The drive component 17 drives the drive shaft 9 to rotate. When the adjustment component 10 moves towards the fixed 1, under the action of the adjustment link 11, the two driven components 12 on the fixed plate 1 move away from each other. Under the action of the driven link 13, the two side adjustment plates 2 rotate away from the fixed plate 1 (that is, the guide support wheels 5 on the two side adjustment plates 2 move away from each other). At the same time, the tensioning component 14 moves towards the fixed plate 1 to ensure that the ring belt 6 is always in a taut state.

[0030] This utility model provides a ring belt tensioning adjustment device for crop vine training devices, which has the following advantages:

[0031] 1. This utility model solves the shortcomings of traditional manual vine lowering, which requires repeated vine lowering and re-hanging.

[0032] 2. This utility model, through the design of a rotatable side adjustment plate, can adjust and lock the spacing of the ring belt to meet the needs of different crop planting.

[0033] 3. The vine-dropping device in this utility model can be reused after installation.
