Description

Technical Field

[0001] The utility model relates to the technical field of cultivation racks, in particular to a cultivation rack. Background Art

[0002] Grape cultivation racks are an indispensable and important facility in grape cultivation. As vine-like fruit trees, grapes cannot stand on their own and need to rely on racks to grow and bear fruit normally. The choice of cultivation racks not only affects the yield and quality of grapes, but also affects the efficiency of management operations such as shaping, pruning, fertilization and irrigation. Traditional trellises and trellises are the two main types of cultivation racks. The trellises are widely used in grape cultivation at home and abroad because of their advantages such as good lighting, easy management, suitable for dense planting and mechanized operation. The trellises provide a larger space, which is conducive to the extension and fruiting of grape branches and vines, and are suitable for use under specific climate and terrain conditions. With the advancement of agricultural technology, the types and designs of grape cultivation racks are also constantly innovating and optimizing to better meet the needs of grape growth and improve planting efficiency.

[0003] For example, a Chinese utility model patent (CN212184451U) discloses a grape cultivation rack, which solves the following problems: In the prior art, fruit farmers erect cement poles in the orchard and tie iron pipes between the cement poles. Under the above method, the construction period is long, the construction labor intensity is high, and it is not easy to manage.

[0004] The device includes: vertical rods, the lower part of which extends into the soil, and the vertical rods are arranged in two parallel rows, and the vertical rods in each row are arranged at equal intervals; connecting rods, the vertical rods form a rectangle, and connecting rods are arranged between adjacent vertical rods on the sides of the rectangle; connecting ropes are arranged between the upper parts of adjacent vertical rods on the sides of the rectangle and between the upper parts of two diagonally arranged vertical rods. The grape cultivation rack provided by the utility model adopts a threaded connection method between the various parts of the entire cultivation rack, which is convenient to install compared with the traditional steel wire binding and fixing method. During the growth process, the grapes will grow towards the area between the two rows of vertical rods, thereby realizing the concentration of the fruiting position and facilitating management.

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: the disassembly and assembly process of the device is cumbersome and inconvenient, so when seasonal disassembly and assembly is carried out or the structure of the cultivation rack needs to be adjusted, a lot of manpower and time will be consumed, resulting in low work efficiency and adverse effects on the growth and yield of grapes. In addition, the device has no structure to support the anti-hail net, and thus cannot effectively resist the attack of hail. Hail will directly impact grape fruits and leaves, causing mechanical damage, and in severe cases even causing fruit rupture and leaf breakage, affecting the yield and quality of grapes. For this reason, we designed a cultivation rack to provide another technical solution to the above technical problems. Utility Model Content

[0047] The utility model adopts the design of the supporting structure to enable the device to retract the anti-hail net, thereby reducing or avoiding the direct impact of hail on grapes, thereby protecting the grape fruits and leaves from damage, which is particularly important for areas that are often hit by hail disasters. The design of the clamping structure of the device makes the installation and disassembly of the steel wire very convenient and reliable. The tight clamping can ensure that it can remain stable under various weather and load conditions, effectively supporting the weight of the grape vines and fruits, and preventing collapse or damage due to structural instability.

[0048] The use process of the cultivation rack provided by the utility model is as follows: the user installs the clamping structure according to the required height, first rotates the handle 17, and then drives the second screw rod 16 and the first screw rod 14 to rotate. Since the threads of the first screw rod 14 and the second screw rod 16 are rotated in opposite directions, the rotation of the first screw rod 14 and the second screw rod 16 drives the two sliding blocks 18 to slide on the outside of the sliding rod 13, and drives the two clamping claws 19 to clamp the U-shaped bracket 1. After the clamping structure is installed, the user passes the wire through the inner side of the plurality of clamping blocks 20, so that The user pulls the handle 29, and then pulls the connecting rod 26 and the first limit block 25, so that the first limit block 25 is disengaged from the meshing connection with the limit wheel 24. The user rotates the handle 32, thereby driving the worm 33 to rotate. One side of the worm 33 is meshed and connected with a worm wheel 34, so that the rotation of the worm 33 drives the worm wheel 34 to rotate, and then drives the rotating column 22 and the cam 23 to rotate, so that the multiple cams 23 can tightly clamp the wire. In the tightly clamped state, the wire is not easy to loosen or fall off, reducing the inconvenience caused by frequent maintenance and replacement. The second bevel gear 6 is meshed with the second bevel gear 6, so that the rotation of the first bevel gear 5 drives the second bevel gear 6 to rotate. Since the bottom of the second bevel gear 6 is fixed with a rotating rod 7, the rotation of the second bevel gear 6 drives the rotating rod 7 to rotate, and then drives the gear 8 to rotate. The two sides of the gear 8 are meshed with racks 9, so that the rotation of the gear 8 drives the two racks 9 to move, and drives the two support rods 10 to move away from each other, thereby supporting the hail net. The main function of the hail net is to keep hail out of the net, reduce or avoid the direct impact of hail on grapes, thereby protecting grape fruits and leaves from damage. This is particularly important for areas that are often affected by hail disasters. In addition to hail, the hail net can also resist the influence of severe weather such as frost, rain and snow on grapes to a certain extent, creating a relatively stable environment for grape growth. In summary, the utility model can enhance structural stability, improve durability, optimize growth conditions, and facilitate management and maintenance, and these benefits together provide a strong guarantee for the high-yield, high-quality and efficient cultivation of grapes.
