Description

Technical Field

[0001] The present application relates to the technical field of grape planting, and in particular to a fixing and tensioning device for grape vine plastic-skinned steel wire and a grape climbing frame having the same. Background Art

[0002] Grape cultivation relies on a grape trellis consisting of columns and plastic-coated steel wire. The steel wire inside the plastic-coated steel wire provides physical support for the grape vines, preventing branches from sagging or breaking due to gravity, wind or rain. The plastic sheathing on the outside of the plastic-coated steel wire can also, to a certain extent, prevent high temperatures caused by sunlight and burns to the grape vines. The existing technology of fixing the steel wire to the column is highly dependent on manual labor, usually by wrapping the end of the steel wire around the column and then spirally wrapping the end of the steel wire around the wire itself to complete the fixation. The above solution has the following problems: 1. The operation process is extremely labor-intensive, and when different steel wires are wound and fixed, some have more turns and some have fewer turns. The tension of the steel wires is also different, making it difficult to ensure consistency in the operation. 2. The steel wire and the grape vines sway in the wind, causing constant friction between the steel wire and the corners of the pillars, resulting in wear and even breakage, causing the entire row of grape vines to fall.

[0003] Therefore, it is necessary to design a fixing and tensioning device that can quickly fix the steel wire and the column and can continuously tighten it to improve the efficiency, stability and consistency of steel wire installation. Summary of the Invention

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0029] A fixing and tensioning device for grape vine plastic-skin steel wire, used for tensioning a steel wire 9 between a pair of support columns 8, comprising a track housing 1, a stopper 2, and a driving device 3; The track housing 1 is arranged along the front-to-back direction; The limiter 2 is sleeved on the steel wire 9, and the limiter 2 allows the steel wire 9 to move forward in one direction.

The limiting housing 21 includes a rectangular base 211, an action lower chamber 212 arranged below the rectangular base 211 in the front-to-back direction, a spring core shaft 213 arranged in the middle of the rear end of the action lower chamber 212, and a spring baffle 214 arranged at the front end of the spring core shaft 213. A hinged column 215 is respectively provided on the left and right sides of the action lower chamber 212. A clamping upper chamber 216 is provided above the front end of the action lower chamber 212. A threading through hole 217 is provided at the rear of the clamping upper chamber 216. A driven slot 218 that cooperates with the active pin 33 is also provided in the left-right direction in front of the lower end face of the rectangular base 211. The slide assembly 22 includes a slide collar 221 slidably mounted on the spring core shaft 213. The slide collar 221 is provided with a clamping arm side opening 222 on the left and right sides, respectively. A slide shaft 223 is provided in each clamping arm side opening 222. A return compression spring 224 is also provided on the spring core shaft 213 between the slide collar 221 and the spring baffle 214. The limiting clamping arms 23 are provided with two, and a pair of limiting clamping arms 23 are arranged in mirror symmetry. The limiting clamping arms 23 include a hinged ring 231 rotatably provided on the hinged column 215, a limiting rear arm 232 provided behind the hinged ring 231, a clamping arm side opening 233 provided on the rear end side of the limiting rear arm 232, a clamping arm rotating shaft 234 provided in the clamping arm side opening 233, a limiting front arm 235 provided in front of the hinged ring 231, and a clamping terminal 236 provided above the limiting front arm 235 and inserted into the clamping upper cavity 216. The limiting rear arm 232 gradually tilts toward the spring core shaft 213 from front to back, and the limiting front arm 235 gradually tilts toward the spring core shaft 213 from back to front. The transmission connecting rod 24 corresponds to the limit clamp arm 23 one by one, the rear end of the transmission connecting rod 24 is hinged to the corresponding clamp arm shaft 234, and the front end of the transmission connecting rod 24 is hinged to the corresponding slide shaft 223. The driving device 3 includes a driving disc 31 rotatably disposed in the driving groove 14 , a hexagonal shaft 32 disposed below the driving disc 31 and passing through the through hole 15 , and a driving pin 33 disposed on the upper end surface of the driving disc 31 .

[0031] This case also discloses a grape climbing frame, comprising a supporting column 8 and a steel wire 9; The support posts 8 are arranged on the ground of the vineyard, with a support post 8 being provided at each end of the ridge of the vineyard; The steel wire 9 is connected to the rope holes of the two support columns 8 to fix and support the grape vines; The end of the steel wire 9 is fixedly connected to the support column 8 through the aforementioned fixing and tensioning device.

[0032] Furthermore, support columns 8 are provided between the two ends of the grape circular ridge in the length direction.

[0033] See the instructions attached Figure 1 It can be seen that: The ends of the steel wire 9 described in this embodiment are passed through the corresponding rope holes of the support column 8. Then, the fixing and tensioning device described in this embodiment is clamped at the end of the wire 9 to quickly secure the wire 9. For some large-span grape planting circles, the length of the steel wire 9 is very long. The fixing and tensioning device provided in this embodiment is used to secure and tension the steel wire 9 in such working conditions.

[0034] It should be noted that the rope threading hole on the support column 8 can be provided with a wear-resistant washer or a wear-resistant cylinder to greatly reduce the wear between the steel wire 9 and the support column 8.

[0035] First, in the case of a fixed tensioning device, the limiter 2 allows the steel wire 9 to pass through the threading hole 217 in one direction, while the steel wire 9 is clamped by the limit clamp arm 23 when moving backward: See the instructions attached Figure 7 、 8 , 12, 13, we can know: The steel wire 9 passes through the threading hole 217 from back to front, and then the wire clamping terminals 236 and the limiting front arms 235 of the pair of limiting clamping arms 23 are pushed outward, and the limiting rear arms 232 move inward and push the slide assembly 2 forward through the transmission connecting rod 24; When the steel wire 9 moves backward, a pair of clamping terminals 236 deflect inwardly to clamp the steel wire 9.

[0036] The pair of limiters 2 provided in this case can both achieve a clamping effect on the steel wire 9. Even if one limiter 2 is damaged, the other one can also ensure that the steel wire 9 will not fall out backwards.

[0037] Then, the fixed tensioning device described in this case also has the function of tensioning the steel wire 9: Insert the hexagonal wrench into the hexagonal shaft 32 and then drive the driving device 3 to rotate; The active pin 33 acts on the driven slot 218 of the rear stopper 2, thereby driving the stopper 2 to move back and forth along the track housing 1; See the instructions attached Figure 2 、 4 It is known; s1. The stopper 2 at the rear moves forward relative to the track housing 1, driving the wire 9 to move forward. At this time, the wire 9 continues to move forward through the stopper 2 at the front; s2. The stopper 2 at the rear relative to the track housing 1 moves backwards from the wire 9, and the wire 9 remains in position due to the effect of the stopper 2 at the front; By looping the above steps s1 and s2 , the steel wire 9 can be intermittently moved forward relative to the track housing 1 , and the steel wire 9 can be gradually tightened.

[0038] It should be noted that when the front stopper 2 fails, the rear stopper 2 is pulled backward by the wire 9. At this time, the cooperation between the driven slot 218 of the rear stopper 2 and the active pin 33 will restrain the stopper 2 and prevent it from falling out of the track housing 1. Furthermore, at least one rear anti-falloff rod 17 is provided at the rear of the upper end surface of the bottom plate 11 of the track housing 1 to stop the stopper 2, further ensuring that the rear stopper 2 will not fall out of the track housing 1.

[0039] It should be noted that an opening inclined surface 237 is provided on the inner side of the front end of the wire clamping terminal 236. When the steel wire 9 moves forward, it acts on the opening inclined surface 237 to push the limiting clamping arm 23 outward.
