Description

Technical Field

[0001] This invention relates to the field of vineyard management technology, specifically to a shading and cold protection device suitable for vineyards in the Northwest China production area, and its construction and usage method. Background Technology

[0002] Grapes are an important fruit tree in my country, with a wide distribution. In summer, intense sunlight and excessively high temperatures cause a large amount of pollen to fall off, resulting in significant flower and fruit drop, reducing both the quantity and quality of grape production. In winter, cold temperatures can cause frost and freezing damage to grapevines. Mild damage may lead to delayed or uneven budding the following year, while severe damage can result in the death of the entire vine, causing significant losses. Furthermore, late spring frosts can easily cause buds, flowers, and even fruit to freeze, damaging the vines, reducing yield, and resulting in substantial economic losses for the orchard.

[0003] Traditionally, in summer, vineyards are typically shaded with black plastic netting, covering all the grapevines to prevent strong sunlight from reaching them and thus avoiding the negative effects of high temperatures. In winter, methods such as burying the vines in soil for frost protection, laying mulch, and wrapping the vines with protective materials are commonly used. However, these shading and frost protection measures are labor-intensive, time-consuming, and costly. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a shading and cold protection device for vineyards in Northwest China, along with its construction and usage method, which solves the problems of complex processes and arduous manual labor involved in shading and cold protection for grapes.

[0019] A method for constructing and using a shading and frost protection device suitable for vineyards in Northwest China includes the following steps:

[0020] First year:

[0021] Install telescopic columns and swing arms:

[0022] During the grape seedling stage, telescopic pillars are first installed at the front and rear ends of the vineyard, and a swing drive arm and a swing driven arm are installed above the telescopic pillars, which are connected by long rod one and long rod two.

[0023] Connect the spiral through hole one of rod one to the upper spiral through hole one of rod two using screw one, so that the telescopic column is in its shortest state.

[0024] Shading operation:

[0025] In summer, shading material is laid on top of the device. Turning the handle causes rod three to swing up and down. Through the connection of long rod one, rod five swings to a horizontal position to provide shade for the seedlings.

[0026] When the seedlings need light, continue to turn the crank handle to make rods three and five swing upwards to increase light exposure.

[0027] Cold weather protection measures:

[0028] In winter, the material on top of the device is replaced with frost-proof material. By turning the crank, rods three and five are swung to the downward position, so that the frost-proof material covers the grapevines and forms a wrap.

[0029] The second year and thereafter:

[0030] Extension device:

[0031] Multiple columns are installed between the telescopic columns at the front and rear ends of the vineyard, and a swing driven arm is installed above them;

[0032] A retractable structure is installed above the entire device, and the laid shading or cold-proof material is connected to the sliding head;

[0033] Adjust height:

[0034] Connect the spiral through hole one of rod one to the lower spiral through hole one of rod two using screw one, so that the telescopic column is in its longest state to accommodate taller grapevines;

[0035] Shading and cold protection measures:

[0036] As in the first year, shading is achieved in the summer by swinging levers three and five with a crank, and in the winter by adjusting the arm lengths of the swing drive arm and the swing driven arm to better cover the grapevines.

[0037] Automatic retraction operation:

[0038] When no shade or cold protection is needed, the motor drives the pulley to rotate counterclockwise, which in turn drives the rope to rotate around the pulley, pushing the connecting rod and sliding head to move along the sliding rod and gather the laid material.

[0039] When shading or cold protection is needed, the motor rotates pulley four clockwise, and the rope drives the connecting rod and sliding head to move, so as to lay the material flat.

[0040] This invention provides a shading and cold protection device suitable for vineyards in Northwest China, along with its construction and usage method. It offers the following beneficial effects:

[0041] 1. The device designed in this invention has both shading and cold protection functions, and can achieve dual use in different seasons. In summer, the device can be used to lay shading materials to effectively reduce the damage of direct sunlight to grapes and prevent grape pollen from falling off and premature fruit drop caused by excessively high temperatures. In winter, the device can be quickly replaced with cold protection materials to wrap the grapevines and prevent low-temperature freezing damage. Compared with traditional shading sheds or manual covering of cold protection materials, this device greatly simplifies the operation process, reduces cumbersome steps, and improves the efficiency of vineyard management.

[0042] 2. This invention is equipped with a shrinking structure, which realizes the automatic shrinking and unfolding of shading and cold protection materials through a combination of motor-driven pulleys and ropes. The automated design avoids the tedious process of manually laying and taking back the materials in the traditional method, which greatly reduces the time and labor costs required for operation. Users only need to control the laying and taking back of the materials through the motor, without frequent manual intervention, which simplifies the workload of daily management of vineyards.

[0043] 3. The telescopic column of this invention, through the spiral through hole and screw connection between rod one and rod two, can be adapted to various vineyard layouts. This function makes the device highly versatile and can be adjusted according to different grapevine growth stages and planting patterns to ensure effective use in different growth cycles.

[0061] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. This is based on the scope of the present invention.

[0062] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a shading and cold protection device suitable for vineyards in the Northwest China production area, comprising:

[0063] Two telescopic columns 1, and multiple columns 2 arranged linearly between the two telescopic columns 1;

[0064] Both telescopic columns 1 include rod 1 6 and screw 11. Rod 2 7 slides inside rod 1 6. A set of spiral through holes 1 8 is provided at the upper end of rod 1 6. A set of upper spiral through holes 1 9 and lower spiral through holes 10 are provided at both the upper and lower ends of rod 2 7. Screw 11 passes through spiral through holes 1 8 and connects to either the set of upper spiral through holes 1 9 or lower spiral through holes 10 on rod 2 7.

[0065] Specifically, the length of the telescopic support column 1 is changed by adjusting the relative sliding between rod 2 (7) and rod 1 (6) to adapt to different vine heights or row spacing requirements. By screwing in screw 11, the screw 11 can pass through the spiral through-hole 8 of rod 1 (6) and connect to the upper spiral through-hole 9 or lower spiral through-hole 10 of rod 2 (7), thereby locking the position of rod 2 (7) and fixing the telescopic support column 1 to the required height. The height of the telescopic support column 1 can be adjusted according to the growth height of the vines, ensuring uniform coverage of shading and cold protection materials throughout the vineyard, improving the adaptability and practicality of the device. Multiple columns 2 are used to support and connect the entire shading and cold protection device's frame structure.

[0066] Please see the appendix Figure 4 - Appendix Figure 8 The swing drive arm 3 is set on top of any telescopic column 1 and is used to drive the sunshade or cold protection material to swing up and down.

[0067] The swing drive arm 3 includes a third rod 14, a fourth rod 15, a large clamping plate 12, and a small clamping plate 13. The upper end of the third rod 14 has a set of spiral through holes 18, and the lower end has two sets of smooth through holes, namely an upper smooth through hole 19 and a lower smooth through hole 20. The fourth rod 15 slides inside the third rod 14. The upper and lower ends of the fourth rod 15 are respectively provided with an upper spiral through hole 21 and a lower spiral through hole 22, and the upper spiral through hole 21 and the lower spiral through hole 22 are connected. Multiple spiral through holes are provided between the two 22s. A set of smooth through holes 23 is provided at the upper end of the four rods 15. A screw 24 is inserted into any set of threaded through holes between the three rods 14 and the four rods 15. An upper protruding cylindrical structure 25 is provided at the upper end of the large clamping plate 12, and a ratchet structure 16 is provided at the lower end of the large clamping plate 12. The upper protruding cylindrical structure 25 passes through the upper smooth through hole 19 of the three rods 14 and is connected to the small clamping plate 13. A rocker handle 17 is rotated at the bottom end of the three rods 14.

[0068] The crank handle 17 includes a protruding cylindrical structure 27, which is installed at one end of the crank handle 17. The other end of the crank handle 17 is equipped with a handle 28 and a protruding cylindrical structure 29. The protruding cylindrical structure 27 passes through a lower smooth through hole 20 and is connected to the rod 14.

[0069] The large clamp plate 12 on the same side is connected by a crossbar, and the bottom of the crossbar is installed at the top of the second bar 7.

[0070] The ratchet structure 16 includes a ratchet 26 and a pawl 30. The ratchet 26 is disposed inside the ratchet structure 16. A connecting cylinder 31 is provided on the ratchet 26. The connecting cylinder 31 is not concentric with the ratchet 26. The connecting cylinder 31 is connected to the protruding cylindrical structure 29. The upper smooth through hole 19 is connected to the large clamping plate 12 through a rotating shaft. The tip of the pawl 30 contacts the outer tooth tip of the ratchet 26.

[0071] Specifically, by adjusting screw 24 between rod 3 (14) and rod 4 (15), the length of the swing arm can be changed to adapt to different shading or cold protection needs. The screw can pass through either the spiral through-hole 2 (18) of rod 3 (14) or any spiral through-hole of rod 4 (15), allowing the length to be adjusted according to the actual conditions of the vineyard to ensure that the shading material can cover the entire area.

[0072] When the angle of the shading or cold-proof material needs to be adjusted, the operator can manually turn the crank handle 17. The rotation of the crank handle 17, through the connection between the protruding cylindrical structure and the smooth through hole, drives the rod 14 to swing up and down, thereby controlling the direction and angle of the material's movement. The crank handle 17 ensures unidirectional movement through the ratchet structure 16, preventing the swing arm from rebounding and enhancing operational safety.

[0073] The ratchet 26 and pawl 30 work together to ensure that the swing arm can only move in one direction when rocking, preventing it from sliding in the opposite direction due to material weight or wind. The user can adjust the locking and unlocking of the swing arm through the ratchet structure 16 to achieve more precise control.

[0074] Please see the appendix Figure 9 - Appendix Figure 10 Multiple sets of swing driven arms 4, each set is installed on the ground through a column 2 and another telescopic column 1, and each set is connected to the swing drive arm 3 through a long rod 58. They swing synchronously with the movement of the drive arm to help coordinate the back and forth swing of the device and make the coverage of the sunshade or cold protection material more even.

[0075] Each of the multiple swing driven arms 4 includes two rods 34. Each of the two rods 34 is respectively set on the top of the column 2 or another telescopic column 1. Each rod 34 has an upper smooth through hole 36 and a lower smooth through hole 37 passing through its lower end. Each rod 34 has a sliding rod 35 inside it. The top of the rod 35 has a smooth through hole 38. The lower smooth through holes 20 on both sides and multiple lower smooth through holes 37 on the same side are connected by a long rod 58. The smooth through holes 23 on both sides and multiple smooth through holes 38 on the same side are connected by a long rod 59.

[0076] A protruding cylindrical structure 39 is provided inside the smooth through hole 2 36. One end of the protruding cylindrical structure 39 is connected to a large clamping plate 2 32, and the other end is connected to a small clamping plate 2 33. The two large clamping plates 2 32 are connected by a crossbar, which is installed at the top of the column 2.

[0077] Specifically, each set of swing driven arms 4 is fixed to the ground by the column 2, forming a stable support structure. The lower end of the fifth rod 34 of the swing driven arm 4 is provided with an upper smooth through hole 36 and a lower smooth through hole 37, and the sixth rod 35 is slidably installed in the fifth rod 34 for easy height adjustment. By adjusting the position of the fifth rod 34 and the sixth rod 35, the length and angle of the swing driven arm 4 can be controlled.

[0078] Long rod 58 connects the lower smooth through hole 20 of the swing drive arm 3 to the lower smooth through hole 37 of the swing driven arm 4, thereby enabling the swing drive arm 3 and the swing driven arm 4 to swing up and down synchronously. Through this connection, the sunshade or cold-proof material of the entire device can move simultaneously at the front and rear ends, achieving a coordinated and consistent coverage effect.

[0079] Meanwhile, the long rod 259 connects the smooth through hole 23 of the swing drive arm 3 with the smooth through hole 38 of the swing driven arm 4, further ensuring the synchronous movement of the two, so that the sunshade or cold protection material maintains a consistent height and angle when covering.

[0080] Large clamping plate 2 32 and small clamping plate 2 33 are connected by protruding cylindrical structure 3 39 and connected to the top of column 2 by crossbar, further enhancing the overall stability of the swing driven arm 4. This design makes the swing driven arm 4 move more smoothly and effectively reduces swaying or uneven swinging caused by external factors.

[0081] Please see the appendix Figure 11 - Appendix Figure 15 The retractable structure 5 is equipped with multiple swing arms above the boom 4 for automatically retracting or expanding the sunshade or cold-proof material.

[0082] The retractable structure includes a sliding rod 40, a pulley 45, and a rope 49. The bottom of the pulley 45 is mounted on a crossbar connected above the opposite side of a set of swinging driven booms 4. A second pulley 46 and a third pulley 47 are mounted on a crossbar connected above the opposite side of another set of swinging driven booms 4. The second pulley 46 and the third pulley 47 are symmetrically placed. A pulley housing 60 is provided on the outside of the telescopic column 1 on the same side. A fourth pulley 48 is provided inside the pulley housing 60. The rope 49 passes over the first pulley 45 and the second pulley 46. Pulley 3 47 and pulley 48, sliding rod 40 is set above multiple sets of swing driven arms 4, multiple hollow cylinders 2 52 slide sequentially on the outer wall of sliding rod 40, one of the hollow cylinders 2 52 is connected to the outer wall of connecting component 42, connecting component 42 includes hollow cylinder 1 50, the middle part of hollow cylinder 1 50 is fixed to the outer wall of rope 49, hollow cylinder 1 50 and hollow cylinder 2 52 are connected by connecting rod 51, and the bottom of multiple hollow cylinders 2 52 are connected by connecting component.

[0083] The connecting assembly includes a sliding head 41, a rod 7 43, and a rod 8 44. The top of the sliding head 41 is installed at the bottom of the hollow cylinder 2 52. A cylinder 53 is installed at the bottom of the sliding head 41. The outer walls of the two cylinders 53 on both sides are respectively connected to rod 7 43 through smooth through hole 5 54 and rod 8 44 through smooth through hole 7 56. The outer walls of the multiple cylinders 53 in the middle are respectively connected to a set of rod 7 43 and rod 8 44 through smooth through hole 5 54 and smooth through hole 7 56. Adjacent rods 8 44 and rod 7 43 are connected by a protruding cylindrical structure 4 57 and a smooth through hole 6 55.

[0084] Specifically, a sliding rod 40 is installed above the device, and multiple hollow cylinders 52 slide sequentially on its outer wall. These hollow cylinders 52 are connected to rods 43 and 44 via sliding heads 41, and these components maintain the stability of the entire retractable structure 5. When the pulley drives the rope 49 to move, sliding occurs between the hollow cylinders 52 and the sliding rod 40, thereby causing the sunshade or cold-proof material to retract and expand.

[0085] Pulley 1 45 is mounted on the crossbar of a set of swing driven arms 4, while pulleys 2 46 and 3 47 are symmetrically mounted on the crossbar of another set of swing driven arms 4, forming the support structure of the pulley system. Through the cooperation of pulley 48 and a motor, rope 49 is driven to wind between the pulleys, thereby controlling the movement of the shading or insulation material. Rope 49 winds around each pulley and transmits the motion to the hollow cylinder and sliding head 41 via connecting rod 51, achieving automatic retraction or expansion of the shading material.

[0086] The top of the sliding head 41 is connected to a hollow cylinder, and the bottom is rotatably connected to rods 7 43 and 8 44 via a cylinder 53. The combination of multiple sliding heads 41 and rods 7 43 and 8 44 ensures smooth movement of material on the sliding rod 40 throughout the entire device. Adjacent sliding components are connected by protruding cylindrical structures and smooth through holes, ensuring coordinated movement of each part and preventing uneven material contraction or expansion.

[0087] Please see the appendix Figure 16 A method for constructing and using a shading and frost protection device suitable for vineyards in Northwest China includes the following steps:

[0088] First year:

[0089] Set up telescopic column 1 and swing arm:

[0090] During the grape seedling stage, telescopic pillars 1 are first installed at the front and rear ends of the vineyard, and swing drive arm 3 and swing driven arm 4 are installed above the telescopic pillars 1, which are connected by long rod 1 58 and long rod 2 59.

[0091] Use screw 11 to connect the spiral through hole 8 of rod 16 to the upper spiral through hole 9 of rod 27, so that the telescopic column 1 is in its shortest state.

[0092] Shading operation:

[0093] In summer, shading material is laid on top of the device. Turning the crank 17 causes the rod 3 14 to swing up and down. Through the connection of the long rod 1 58, the rod 5 34 swings to a horizontal position to provide shade for the seedlings.

[0094] When the seedlings need light, continue to turn the crank 17 so that rods 14 and 34 swing upwards to increase light exposure.

[0095] Cold weather protection measures:

[0096] In winter, the material on top of the device is replaced with a cold-proof material. By turning the crank 17, the rods 14 and 34 are swung to the downward position, so that the cold-proof material covers the grapevines and forms a wrap.

[0097] The second year and thereafter:

[0098] Extension device:

[0099] Multiple columns 2 are set between the telescopic columns 1 at the front and rear ends of the vineyard, and a swing driven arm 4 is installed above them;

[0100] A retractable structure 5 is installed above the entire device, and the laid shading or cold-proof material is connected to the sliding head 41;

[0101] Adjust height:

[0102] Use screw 11 to connect the spiral through hole 8 of rod 16 to the lower spiral through hole 10 of rod 27, so that the telescopic column 1 is in its longest state to accommodate taller grapevines.

[0103] Shading and cold protection measures:

[0104] As in the first year, in summer, the shading is achieved by swinging lever 3 14 and lever 5 34 through crank 17, and in winter, the vines are better covered by adjusting the arm length of swing drive arm 3 and swing slave arm 4.

[0105] Automatic retraction operation:

[0106] When no shade or cold protection is needed, the motor drives pulley 48 to rotate counterclockwise, which drives rope 49 to rotate around the pulley, pushing connecting rod 51 and sliding head 41 to move along sliding rod 40 to gather the laid material.

[0107] When shading or cold protection is needed, the motor rotates pulley 48 clockwise, and rope 49 drives connecting rod 51 and sliding head 41 to move, so as to achieve the flat laying of materials.
