Description

Technical Field

[0001] The present invention relates to the technical field of fruit and vegetable planting production, and particularly to an automatic crop vine-lowering and vine-thinning system. Background Art

[0002] In the production of fruit and vegetables in solar greenhouse facilities, vine-lowering, vine-thinning, and vine-winding operations are indispensable links. For indeterminate growth type high-vine climbing crops such as cucumbers, tomatoes, and peppers, during the growth process, the continuously growing stem vines need to be lowered, coiled, or lifted with supports. During the full-fruit period of fruit and vegetables, the leaves grow vigorously, and the distance between adjacent rows of vines will become smaller, affecting the lighting and ventilation of the leaves. In order to improve the yield and quality, and improve the uniformity of lighting and air circulation, it is also necessary to thin the vines between adjacent rows. At present, vine-lowering, vine-winding, and vine-thinning operations are mainly manual, and the simplest vine-lowering device is the most widely used, which seriously restricts the production efficiency of current facility fruit and vegetables in China. In actual vine-lowering operations, planting personnel need to perform operations one by one, resulting in low labor operation efficiency and high labor intensity, and increasing labor costs invisibly. Summary of the Invention

[0039] As Figure 1 shown, the crop automatic vine-lowering and vine-thinning system provided by the embodiment of the present invention includes a vine-lowering device 1 and a vine-thinning device 2. The vine-lowering device 1 includes multiple pairs of vine-supporting shafts 11, a vine-lowering device 12, and a first driving assembly 13. The vine-lowering device 12 is disposed on the vine-supporting shaft 11, and the first driving assembly 13 is used to drive the vine-supporting shaft 11 to rotate so as to drive the vine-lowering device 12 to rotate and lower the vines. The vine-thinning device 2 includes a guiding assembly 21 and a second driving assembly 22. The end of the vine-supporting shaft 11 is disposed on the guiding assembly 21, and the guiding assembly 21 is disposed horizontally and perpendicular to the axial direction of the vine-supporting shaft 11. The second driving assembly 22 is used to drive the two vine-supporting shafts 11 in each pair of vine-supporting shafts 11 to move relatively or away from each other along the guiding assembly 21.

[0040] In the crop automatic vine-lowering and vine-thinning system of the embodiment of the present invention, at the beginning of the production operation, the first driving assembly 13 is first turned on to drive the vine-supporting shaft 11 to rotate. The vines are connected to the vine-lowering device 12. During the rotation of the vine-supporting shaft 11, the vine-lowering device 12 is driven to rotate, so that the position of the vines drops, and the overall vine-lowering operation is realized. After the vine-lowering operation is completed, the second driving assembly 22 is turned on. The second driving assembly 22 drives the vine-supporting shaft 11 to move along the guiding assembly 21. In the present invention, the vine-supporting shafts 11 are arranged in pairs on the same horizontal plane. The two vine-supporting shafts 11 in each pair of vine-supporting shafts 11 approach or move away from each other under the drive of the second driving assembly 22, so that the vines connected to the vine-lowering devices 12 on the two vine-supporting shafts 11 approach or move away from each other, and the overall vine-thinning action is realized. Thus, the crop automatic vine-lowering and vine-thinning system of the present invention can simultaneously complete the production operations of automatic vine-lowering and vine-thinning for multiple rows and the whole greenhouse fruit and vegetable vines, increase the distance between adjacent two rows of vines, improve the uniformity of lighting and the air circulation, and further improve the yield and quality, while saving labor costs.

[0041] Among them, as Figure 2 、 Figure 3 and Figure 4As shown in the figure, the first driving assembly 13 includes a first driver 131, a first transmission shaft 132, a belt 133, and a pulley 134. The pulley 134 is disposed at the end of the vine hanging shaft 11 and is coaxially connected to the vine hanging shaft 11. The first driver 131 is used to drive the first transmission shaft 132 to rotate. The first transmission shaft 132 is connected to the pulley 134 through the belt 133 to drive the pulley 134 to rotate. In this embodiment, a first transmission wheel 34 corresponding to the pulley 134 is provided on the first transmission shaft 132. The first transmission wheel 34 is coaxially arranged with the first transmission shaft 132. The first transmission wheel 34 is connected to its corresponding pulley 134 through the belt 133 to form a transmission chain. The first driver 131 drives the first transmission shaft 132 to rotate, and the first transmission wheel 34 rotates accordingly to drive the pulley 134 to rotate. The pulley 134 is disposed at the end of the vine hanging shaft 11, so the rotation of the vine hanging shaft 11 is realized.

[0042] In this embodiment, the first driver 131 adopts a first reduction motor. The first reduction motor is connected to the first transmission shaft 132 through a first coupling 31. The first reduction motor and the first motor base 35 are fixed by bolts. The first transmission shaft 132 is fixedly connected to the first support base 33 through a first bearing block 32. The first motor base 35 and the first support base 33 are fixed to the rear wall of the solar greenhouse. The first reduction motor adopts frequency conversion control to drive the first transmission shaft 132 to rotate at a uniform speed of 3-5 revolutions per minute. The vine hanging shaft 11 is driven by the pulley 134 and the belt 133 to achieve uniform linkage, so that the vine dropping device 12 rotates at a uniform speed for the overall vine dropping operation. In other embodiments, the first driver 131 can also drive other types of transmission mechanisms to drive the vine hanging shaft 11 to rotate, such as a chain-gear mechanism, etc., which is not limited by this embodiment.

[0043] Among them, such as Figure 5As shown in the figure, the vine-lowering device 12 includes a driving gear 121, a driven gear 122, a vine-lowering wire wheel 123 and two clamping plates 124. The driving gear 121 is arranged on the vine-suspending shaft 11 and is detachably connected to the vine-suspending shaft 11 coaxially. The driven gear 122 meshes with the driving gear 121, and the driven gear 122 is fixedly connected to the vine-lowering wire wheel 123 coaxially. The two clamping plates 124 are arranged oppositely and connected, and both the driving gear 121 and the driven gear 122 are arranged between the two clamping plates 124. In this embodiment, the driving gear 121 and the driven gear 122 are engaged and matched to form a gear pair. The driving gear 121 and the driven gear 122 of each vine-lowering device 12 maintain meshing transmission between the two clamping plates 124. The vine-suspending shaft 11 passes through the central shaft hole of the driving gear 121. When the vine-suspending shaft 11 is driven to rotate by the first driving assembly 13, it can drive the driving gear 121 to rotate. The driven gear 122 meshes and rotates with the driving gear 121. The vine-lowering wire wheel 123 is coaxially connected to the driven gear 122. The driven gear 122 drives the vine-lowering wire wheel 123 to rotate. The stem vine is wound on the wire rope of the vine-lowering wire wheel 123. During the rotation of the vine-lowering wire wheel 123, the wire rope gradually moves down and extends, thereby realizing vine lowering. Thus, a vine-lowering and thinning system based on manual vine winding is formed. Based on manual-assisted vine winding, the production operation problems of simultaneous automatic vine lowering and thinning for multiple rows and the entire greenhouse are solved.

[0044] In this embodiment, the two clamping plates 124 are fixed by bolts 41. The driving gear 121 is connected to the clamping plate 124 through a first shaft sleeve 42, and the driven gear 122 is connected to the clamping plate 124 through a second shaft sleeve 43. The axis direction of the driving gear 121 passes through the vine-suspending shaft 11 and is fixed by a first set screw 44. A transmission rod 46 is arranged in the axis direction of the driven gear 122 and is fixed by a second set screw 45. The hexagonal rod section on the transmission rod 46 is detachably connected to the hexagonal shaft hole in the middle of the vine-lowering wire wheel 123. After the vine thinning operation is completed, the vine-lowering wire wheel 123 on a vine-suspending shaft 11 can be removed from the transmission rod 46 manually, and then exchanged with the vine-lowering wire wheel 123 on the other vine-suspending shaft 11 paired with this vine-suspending shaft 11. The vine-lowering wire wheel 123 on the other vine-suspending shaft 11 performs the same operation to realize the vine winding operation. In this embodiment, a plurality of vine-lowering devices 12 are evenly arranged on a vine-suspending shaft 11, and the vine-lowering devices 12 on the paired vine-suspending shafts 11 are arranged correspondingly, which is convenient for vine winding operation.

[0045] Among them, as Figure 6 、 Figure 7 and Figure 4As shown in the figure, the guiding assembly 21 includes a hanging vine shaft support base 211 and a support rod 212. The support rod 212 is arranged horizontally and perpendicular to the axial direction of the hanging vine shaft 11. The hanging vine shaft support base 211 is arranged along the axial direction of the support rod 212 and connected to the support rod 212. A guiding hole 213 extending along the axial direction of the support rod 212 is provided on the hanging vine shaft support base 211, and the end of the hanging vine shaft 11 passes through the guiding hole 213. In this embodiment, the support rod 212 is arranged perpendicular to the hanging vine shaft 11 above the hanging vine shaft 11, and a hanging vine shaft support base 211 corresponding to each hanging vine shaft 11 is fixed on the support rod 212. The end of the hanging vine shaft 11 passes through the guiding hole 213 formed on the hanging vine shaft support base 211, so as to realize the support of the hanging vine shaft 11 by the hanging vine shaft support base 211. The second driving assembly 22 drives the hanging vine shaft 11 to move along the guiding hole 213, so as to realize the movement of the hanging vine shaft 11 in the horizontal direction, increase the distance between the vines on the two paired hanging vine shafts 11, improve the uniformity of lighting and the air circulation, and thus improve the yield and quality.

[0046] In this embodiment, the hanging vine shaft support base 211 is fixed on the support rod 212 by a U-shaped clamp 7. A first fixing bracket 51 is further arranged on the support rod 212 and connected to the greenhouse framework through the first fixing bracket 51.

[0047] Among them, as Figure 1 and Figure 2As shown in the figure, the second driving assembly 22 includes a second driver 221, a second transmission shaft 222, and a transmission rope 223. A vine hanging shaft sleeve 214 is provided at the contact position of the vine hanging shaft 11 and the vine hanging shaft support seat 211. The second driver 221 is used to drive the second transmission shaft 222 to rotate. The second transmission shaft 222 is connected to the vine hanging shaft sleeve 214 through the transmission rope 223. The vine hanging shaft sleeves 214 corresponding to the two vine hanging shafts 11 in each pair of vine hanging shafts 11 are respectively connected to two rope segments with opposite moving directions on the transmission rope 223. In this embodiment, a vine hanging shaft sleeve 214 is provided at the end of the vine hanging shaft 11. The vine hanging shaft support seat 211 contacts the vine hanging shaft sleeve 214. The vine hanging shaft sleeve 214 does not rotate with the vine hanging shaft 11, but moves along the guide hole 213 following the vine hanging shaft 11. When the second driver 221 drives the second transmission shaft 222 to rotate right, the second transmission shaft 222 is connected to the transmission rope 223, thereby driving the transmission rope 223 to perform a right-rotating closed-loop rotary motion, that is, the upper rope segment of the transmission rope 223 moves from left to right, and the lower rope segment of the transmission rope 223 moves from right to left. The upper rope segment of the transmission rope 223 is connected to the vine hanging shaft sleeve 214 of the vine hanging shaft 11 that moves from the left end to the right end of its corresponding guide hole 213 in each pair of vine hanging shafts 11. The lower rope segment of the transmission rope 223 is connected to the vine hanging shaft sleeve 214 of the vine hanging shaft 11 that moves from the right end to the left end of its corresponding guide hole 213 in each pair of vine hanging shafts 11. When the second driver 221 drives the second transmission shaft 222 to rotate left, this realizes that the transmission rope 223 drives the two vine hanging shafts 11 of the paired vine hanging shafts 11 to approach or move away from each other, completing the operation of thinning vines.

[0048] In this embodiment, the second driver 221 uses a second reduction motor. The second reduction motor is connected to the second transmission shaft 222 through a second coupling 61. The second reduction motor and the second motor seat 65 are fixed by bolts. The second transmission shaft 222 is fixedly connected to the second support seat 63 through a second bearing seat 62. The second motor seat 65 and the second support seat 63 are fixed to the side wall of the solar greenhouse. The second reduction motor adopts frequency conversion control, driving the second transmission shaft 222 to rotate at a uniform speed of 3 - 5 revolutions per minute. The transmission rope 223 drives the vine hanging shaft sleeve 214 to move, realizing the movement of the vine hanging shaft 11 to complete the overall operation of thinning vines. In this embodiment, the transmission rope 223 uses a steel wire rope. In other embodiments, the second driver 221 can also drive other types of transmission mechanisms to drive the vine hanging shaft 11 to move, and the transmission rope 223 can also use other types, which are not limited by this embodiment.

[0049] Among them, as Figure 4 and Figure 6As shown, the transmission rope 223 is connected to the hanging vine shaft bushing 214 through the wire pressing clip 215. In this embodiment, the wire pressing clip 215 is fixed on the hanging vine shaft bushing 214. According to the thinning vine moving direction of the hanging vine shaft 11, it is respectively connected and fixed to the upper rope segment or the lower rope segment of the transmission rope 223, so that the transmission rope 223 drives the hanging vine shaft bushing 214 fixed thereto to move during the rotary transmission process. The fixing method of the wire pressing clip 215 is convenient for disassembly and replacement of parts. In other embodiments, the transmission rope 223 can also be fixed to the hanging vine shaft bushing 214 in other ways, such as welding, gluing, by screwing and winding, etc.

[0050] Among them, as Figure 4 , Figure 5 and Figure 9 shown, the hanging vine shaft bushing 214 is connected to the clamping plate 124 through the tensioning member 216. In this embodiment, a plurality of vine dropping devices 12 are provided on one hanging vine shaft 11. A connecting portion connected to the tensioning member 216 is provided at the bottom of the clamping plate 124 of each vine dropping device 12. The tensioning member 216 successively connects in series the hanging vine shaft bushing 214 of the hanging vine shaft 11 and each connecting portion, so as to fix the position of the clamping plate 124 on the hanging vine shaft 11, and avoid that during the vine dropping process, the rotation of the hanging vine shaft 11 drives the clamping plate 124 of the vine dropping device 12 to rotate synchronously, affecting the stable rotation of the vine dropping wire wheel 123. In this embodiment, the tensioning member 216 adopts a pulling steel wire rope.

[0051] Among them, as Figure 6 and Figure 9As shown, the guide hole 213 is an arc-shaped hole, and the end of the arc-shaped hole where the two hanging vine shafts 11 in each pair of hanging vine shafts 11 are closest to each other is lower than the end where the two hanging vine shafts 11 are farthest from each other. In this embodiment, the guide hole 213 is an arc-shaped hole, and the two guide holes 213 of the hanging vine shafts 11 arranged in pairs are symmetrically arranged on their corresponding hanging vine shaft support seats 211. Since the first transmission wheel 34 on the first transmission shaft 132 is connected to the pulley 134 through the belt 133, the pulley 134 will move horizontally with the hanging vine shaft 11 during the horizontal movement of the hanging vine shaft 11 along the guide hole 213. Therefore, the pulley 134 will change from the original relationship of being directly opposite to the first transmission wheel 34 to being offset from the first transmission wheel 34 by a certain distance. The distance between the first transmission wheel 34 and the first transmission wheel 34 will become larger, causing the belt 133 to be subjected to tension. Therefore, in order to ensure the service life of the belt 133 and avoid repeated tension damage, the guide hole 213 is designed to be an arc, that is, the first transmission wheel 34 is taken as the center of the circle and the belt 133 is taken as the radius to draw an arc to form the guide hole 213, and the end of the guide hole 213 staggered from the first transmission wheel 34 is higher than the end of the guide hole 213 directly facing the first transmission wheel 34, so that the pulley 134 always keeps a distance from the first transmission wheel 34 during the horizontal movement of the hanging vine shaft 11. In other embodiments, the guide hole 213 can also be designed as a horizontal guide hole, and the first transmission wheel 34 located on the first transmission shaft 132 must have a certain mobility, that is, the first transmission wheel 34 is movably connected to the first transmission shaft 132.

[0052] Among them, Figure 6 , Figure 8 and Figure 10 As shown, the second drive assembly 22 also includes a third transmission shaft 224 and a fourth transmission shaft 225. The third transmission shaft 224 and the fourth transmission shaft 225 are both parallel to the hanging vine shaft 11 and are arranged at the same horizontal plane as the hanging vine shaft 11. The transmission rope 223 is sequentially passed around the second transmission shaft 222, the hanging vine shaft 11, the third transmission shaft 224 and the fourth transmission shaft 225 along its transmission direction. In this embodiment, the second transmission shaft 222, the third transmission shaft 224 and the fourth transmission shaft 225 are arranged at the same time in the transmission direction of the transmission rope 223, wherein the hanging vine shaft 11 is arranged between the third transmission shaft 224 and the fourth transmission shaft 225. In order to make full use of the space and reduce the floor space, the plane where the second transmission shaft 222 and the third transmission shaft 224 are located is perpendicular to the plane where the third transmission shaft 224 and the fourth transmission shaft 225 are located. The third transmission shaft 224 and the fourth transmission shaft 225 are both provided with a second transmission wheel 64. The transmission rope 223 is wound around the second transmission shaft 222, passes through the second transmission wheel 64 of the third transmission shaft 224, passes through the sling shaft support seat 211 of the sling shaft 11, then passes through the second transmission wheel 64 of the fourth transmission shaft 225, winds back, passes through the sling shaft support seat 211 of the sling shaft 11, and finally bypasses the second transmission wheel 64 of the third transmission shaft 224 to form a closed-loop transmission chain.

[0053] In this embodiment, the third transmission shaft 224 is fixed to the third support seat 66 through the U-shaped clamp 7, and the third support seat 66 is fixed to the side wall of the solar greenhouse. The fourth transmission shaft 225 is fixed to the second fixing bracket 52 through the U-shaped clamp 7, and the second fixing bracket 52 is further fixed to the greenhouse framework.
