Description

Technical Field

[0001] This utility model relates to the field of crop vine dropping technology, and in particular to a driving device for crop vine dropping 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] In view of the above-mentioned defects, the purpose of this utility model is to provide a driving device for crop vine dropping devices, which can be reused, shortens the time required for vine dropping, improves the efficiency of vine dropping, 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 driving device for a crop vine-dropping system, 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 mounted on each side adjustment plate; a main hanging shaft and a drive shaft rotatably connected between the fixed plates, with a plurality of hanging ropes connected to the main hanging shaft, and an annular belt below the main hanging shaft that cooperates with the guide support wheels, the annular belt having hanging rope hooks that cooperate with the hanging ropes; and a main forward shaft sleeve, a secondary forward shaft sleeve, and a reverse shaft sleeve rotatably mounted on the drive shaft. The bushing has an adjusting member connected to the main positive bushing. Two driven members are slidably provided on each of the fixed plates. An adjusting link is rotatably provided between adjacent adjusting members and driven members. A driven link is rotatably provided between adjacent driven members and the side adjusting plate. A tensioning member is connected to the secondary positive bushing. A tensioning support wheel is provided on the tensioning member. A locking slider is provided on the reverse bushing. A lifting member is slidably provided below the fixed plate. A rack is provided on the lifting member. A locking gear is provided on the main positive bushing. A locking link is rotatably provided between the lifting member and the locking slider.

[0006] According to the driving device for the crop vine dropping device of this utility model, both the main positive shaft sleeve and the secondary positive shaft sleeve are provided with positive ratchet wheels, the reverse shaft sleeve is provided with a reverse ratchet wheel, and the drive shaft is rotatably provided with positive pawls and reverse pawls.

[0007] According to the driving device for the crop vine dropping device of this utility model, each tensioning member is fixedly provided with a horizontal extension plate, and each extension plate is slidably provided with a tensioning slider below it. The bottom end of the tensioning slider is rotatably connected to a tensioning support wheel.

[0008] According to the driving device for the crop vine dropping device of this utility model, a spring is provided between the adjacent tensioning member and the tensioning slider, and the spring is always in a compressed state.

[0009] According to the driving device for the crop vine dropping device of this utility model, the main shaft of the hanging rope is provided with a plurality of hanging rope rings, and the hanging rope is connected to the hanging rope rings.

[0011] The purpose of this invention is to provide a ring belt tensioning adjustment device for crop vine training devices, which has the following advantages:

[0012] 1. This utility model solves the shortcomings of traditional manual vine lowering, which requires repeated vine lowering and re-hanging. When the hanging rope is tied to the vine, when it is necessary to lower the vine height multiple times, there is no need to repeatedly separate and connect the hanging rope to the vine. Simply rotate the main shaft of the hanging rope to lower the hanging rope to reduce the vine height, thereby improving the efficiency of vine lowering and avoiding the disadvantage of traditional vine lowering methods that are prone to damaging the vine.

[0013] 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.

[0014] 3. The vine-dropping device in this utility model can be reused after installation. After the vine-dropping is completed, the hanging rope can be wound up through the main hanging shaft of the hanging rope. There is no need to remove the hanging rope separately. When the next crop needs to be hung and dropped, the rope can be released directly. This effectively reduces the manual labor intensity during vine-dropping operations and effectively improves the efficiency of vine-dropping. The design is scientific and reasonable and highly practical. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. 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 driving device for a crop vine-dropping device.

[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 their connection point with 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 8 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 8. A drive component is mounted on one of the fixed plates 1. A belt is provided between the output shaft of the drive component and the drive shaft 8. The drive component can drive the drive shaft 8 to reciprocate.

[0024] A main forward sleeve 9 is rotatably sleeved on the drive shaft 8. A positive ratchet is provided on one side wall of the main forward sleeve 9. The positive ratchet, the main forward sleeve 9 and the drive shaft 8 are concentric. A positive pawl that can rotate in one direction is rotatably connected to the drive shaft 8. When the drive shaft 8 rotates forward, the positive ratchet and the positive pawl cooperate, so that the drive shaft 8 can drive the main forward sleeve 9 to rotate forward. The main forward sleeve 9 cooperates with the adjusting member 11 (the cooperation method is the same as that of the reciprocating screw, that is, the surface of the main forward sleeve 9 is provided with a reciprocating groove that cooperates with the adjusting member 11, so that when the main forward sleeve 9 rotates in one direction, the adjusting member 11 can reciprocate along the main forward sleeve 9).

[0025] A secondary positive bushing 19 is rotatably fitted on the drive shaft 8. One end of the secondary positive bushing 19 also has a positive ratchet. The positive ratchet, the secondary positive bushing 19, and the drive shaft 8 are concentric. A unidirectional rotatable positive pawl is rotatably connected to the drive shaft 8. The secondary positive bushing 19 cooperates with the tensioning element (its cooperation method is the same as that of the main positive bushing 9 and the adjusting element 11). A horizontal extension plate is fixedly connected to each tensioning element. A tensioning slider 20 is slidably connected to the bottom surface of each extension plate. A tensioning support wheel 21 is rotatably connected to the bottom surface of the tensioning slider 20. The tensioning support wheel 21 can cooperate with the annular belt 6. A spring is provided between each adjacent tensioning slider 20 and the tensioning element. The spring is always in a compressed state.

[0026] A reverse sleeve 15 is rotatably fitted onto the drive shaft 8. A reverse ratchet (opposite to the forward ratchet) is provided on one side wall of the reverse sleeve 15. A unidirectional rotatable reverse pawl is rotatably mounted on the drive shaft 8. When the drive shaft 8 reverses direction, the reverse ratchet engages with the reverse pawl, causing the reverse sleeve 15 to reverse direction along with the drive shaft 8 (during this process, the main forward sleeve 9 and the secondary forward sleeve 19 do not rotate). A locking slider 16 is fitted onto the reverse sleeve 15 (its engagement method is the same as that of the main forward sleeve 9). A lifting component 18 is slidably connected below the fixed plate 1 (and adjusting component 11). A rack is fixedly connected to the top surface of the lifting component 18. A locking gear 10 that can mesh with the rack is fixedly connected to the main positive bushing 9. When the locking gear 10 meshes with the rack, it can lock the main positive bushing 9. A locking link 17 is rotatably connected between the locking slider 16 and the lifting component 18. One end of the locking link 17 is rotatably connected to the locking slider 16, and the other end of the locking link 17 is rotatably connected to the lifting component 18.

[0027] See Figures 1-3 Preferably, both the drive mechanism and the drive components are rotary motors, which can provide sufficient power.

[0028] See Figures 1-3 Preferably, both the guide support wheel 5 and the tension support wheel 21 are provided with grooves that cooperate with the annular belt 6, which can reduce the risk of the annular belt 6 falling off.

[0029] See Figures 1-3Preferably, when the drive shaft 8 rotates forward, the adjusting member 11 located at the same end of the drive shaft 8 moves in the opposite direction to the tensioning member.

[0030] See Figures 1-3 Preferably, each of the fixed plates 1 is fixedly connected with a limiting rod that passes through the locking slider 16 and the tensioning slider 20. The limiting rod can prevent the locking slider 16 and the tensioning slider 20 from rotating.

[0031] In the implementation of this utility model: when it is necessary to adjust the width of the annular belt 6, the user starts the drive unit, which rotates forward. At this time, the positive ratchet engages with the positive pawl, while the negative ratchet does not engage with the negative pawl. The main positive bushing 9 and the secondary positive bushing 19 rotate forward, while the negative bushing 15 does not rotate. When the adjusting member 11 moves towards the fixed plate 1, under the action of the adjusting link 12, the two driven members 13 on the fixed plate 1 move away from each other. Under the action of the driven link 14, the side adjusting plates 2 at both ends of the fixed plate 1 rotate synchronously (i.e., the two side adjusting plates 2 at both ends of the fixed plate 1 rotate synchronously). The guide support wheels 5 move away from each other, increasing the usable width of the annular belt 6. At the same time, the tensioning member moves towards the fixed plate 1 to prevent the annular belt 6 from breaking. After adjustment, the drive member reverses. At this time, the positive ratchet does not engage with the positive pawl, and the negative ratchet engages with the negative pawl. The main positive bushing 9 and the secondary positive bushing 19 do not rotate, and the reverse bushing 15 reverses, causing the lifting member 18 to rise until the rack engages with the locking gear 10, thus locking the main positive bushing 9. (Before adjusting the usable width of the annular belt, the rack and locking gear 10 must be in a non-engaged state.)

[0032] This utility model provides a ring belt tensioning adjustment device for crop vine training devices, which has the following advantages:

[0033] 1. This utility model solves the shortcomings of traditional manual vine lowering, which requires repeated vine lowering and re-hanging. When the hanging rope is tied to the vine, when it is necessary to lower the vine height multiple times, there is no need to repeatedly separate and connect the hanging rope to the vine. Simply rotate the main shaft of the hanging rope to lower the hanging rope to reduce the vine height, thereby improving the efficiency of vine lowering and avoiding the disadvantage of traditional vine lowering methods that are prone to damaging the vine.

[0034] 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.

[0035] 3. The vine-dropping device in this utility model can be reused after installation. After the vine-dropping is completed, the hanging rope can be wound up through the main hanging shaft of the hanging rope. There is no need to remove the hanging rope separately. When the next crop needs to be hung and dropped, the rope can be released directly. This effectively reduces the manual labor intensity during vine-dropping operations and effectively improves the efficiency of vine-dropping. The design is scientific and reasonable and highly practical.

[0036] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
