[0002] Grapes are an important fruit tree in my country, with a wide distribution range. In summer, the strong sunlight and high temperature will cause a large amount of grape pollen to fall, resulting in a large number of grape flowers and fruits falling, reducing the quantity and quality of grape production. In winter, the temperature is cold, and grapes may suffer from frost and frost damage. In mild cases, the germination of the next year is delayed or uneven, and in severe cases, the whole plant dies and causes losses. When the late spring cold comes, grapes are prone to frozen buds, frozen flowers, and even frozen fruits, causing damage to the tree, reduced yield, and significant economic losses to the orchard.

[0003] In the traditional method, in summer, a sunshade or awning is usually built for the vineyard, and a black plastic shade net is added to cover all the grape plants to prevent strong light from shining on the grape plants and avoid the impact of high temperature on the grapes.

[0019] A method for constructing and using a vineyard sunshade and cold protection device suitable for the northwest production area, comprising the following steps:

[0020] First Year:

[0021] Setting up the telescopic column and swing arm:

[0022] In the grape seedling stage, firstly, telescopic columns are respectively set at the front and rear ends of the vineyard, and a swing driving arm and a swing driven arm are installed above the telescopic columns, and connected by long sticks 1 and 2;

[0023] Use screw 1 to connect the spiral through hole 1 of rod 1 with the upper spiral through hole 1 of rod 2, so that the telescopic column is in the shortest state;

[0024] Sunshade operation:

[0025] In summer, sunshade material is laid on the top of the device, and the crank is turned to drive the rod three to swing up and down. Through the connection of the long stick one, the rod five swings to a horizontal position to achieve sunshade for the seedlings.

[0026] When the seedlings need light, continue to turn the handle to swing the third and fifth rods upward to increase light.

[0027] Cold protection operation:

[0028] In winter, the material on the top of the device is replaced with anti-cold material, and the handle is turned to swing the rods three and five to a downward position so that the anti-cold material covers the grapevine to form a package;

[0029] Second year and thereafter:

[0030] Extension device:

[0031] A plurality of upright posts are arranged between the telescopic upright posts at the front and rear ends of the vineyard, and swing follower arms are installed above the upright posts;

[0032] Set up a retractable structure above the entire installation and connect the laid shading or cold-proofing material to the sliding head;

[0033] Adjust the height:

[0034] Use screw 1 to connect the spiral through hole 1 of rod 1 with the lower spiral through hole 1 of rod 2, so that the telescopic column is in the longest state to accommodate taller grapevines;

[0035] Sunshade and cold protection operation:

[0036] Same as the first year, in summer, the three and five levers are swung by the crank control to provide shade, and in winter, the length of the swing driving arm and the swing follower arm are adjusted to better cover the vines;

[0037] Automatic shrink operation:

[0038] When shading or cold protection is not needed, the motor is used to drive the pulley to rotate counterclockwise, driving the rope to rotate around the pulley, pushing the connecting rod and the sliding head to move along the sliding rod to collect the laid materials;

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

[0040] The present invention provides a vineyard sunshade and cold protection device suitable for the northwest production area and a construction and use method thereof. It has the following beneficial effects:

[0041] 1. The device designed by the present invention has the functions of sunshade and cold protection, and can achieve dual purposes in different seasons. In summer, the device can lay sunshade materials to effectively reduce the damage to grapes caused by direct sunlight and avoid the drop of grape pollen and early shedding of fruits caused by excessively high temperatures. In winter, the device can be quickly replaced with cold-proof materials to wrap the grape vines to prevent low temperature damage. Compared with traditional sunshades or artificial covering methods with cold-proof materials, this device greatly simplifies the operating process, reduces cumbersome steps, and improves the efficiency of vineyard management.

[0042] 2. The present invention is equipped with a retractable structure, which realizes the automatic retraction and expansion of sunshade and cold-proof materials through the combination of motor-driven pulleys and ropes. The automated design avoids the tedious process of manually laying and folding materials step by step in the traditional method, greatly reducing the time and labor costs required for operation. Users only need to control the laying and folding of materials through the motor, without frequent manual intervention, simplifying the workload of daily vineyard management.

[0043] 3. The telescopic column of the present invention is suitable for various vineyard layouts by changing the length of the first and second connecting rods through the spiral through holes and screws. This function makes the device highly universal and can be adjusted according to different grapevine growth stages and planting patterns to ensure effective use in different growth cycles.

DETAILED DESCRIPTION

[0061] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the scope of the present invention.

[0062] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a sunshade and cold-proof device for vineyards in the northwest production area, comprising:

[0063] Two telescopic columns 1, with a plurality of columns 2 arranged linearly between the two telescopic columns 1;

[0064] The two telescopic columns 1 each include a rod 6 and a screw 11, a rod 7 slides inside the rod 6, a group of spiral through holes 8 are penetrated at the upper end of the rod 6, a group of upper spiral through holes 9 and lower spiral through holes 10 are penetrated at the upper and lower ends of the rod 27, and the screw 11 penetrates the spiral through holes 8 and is connected to any group of upper spiral through holes 9 or lower spiral through holes 10 on the rod 27.

[0065] Specifically, by adjusting the relative sliding between the rod 27 and the rod 16, the length of the telescopic column 1 can be changed to adapt to different grapevine heights or row spacing requirements, and by screwing in the screw 11, the screw 11 can be passed through the spiral through hole 18 of the rod 16 and connected with the upper spiral through hole 19 or the lower spiral through hole 10 of the rod 27, thereby locking the position of the rod 27, so that the telescopic column 1 reaches the required height and is fixed. The height of the telescopic column 1 can be adjusted according to the growth height of the grapevine, ensuring that the sunshade and cold-proof materials are evenly covered throughout the vineyard, improving the adaptability and practicality of the device. Multiple columns 2 are used to support and connect the skeleton structure of the entire sunshade and cold-proof device.

[0066] Please see attached Figure 4 -Attached Figure 8 , a swing driving arm 3, which is arranged on the top of any telescopic column 1, and is used to drive the sunshade or cold-proof material to swing up and down;

[0067] The swing drive arm 3 includes a rod 3 14, a rod 4 15, a large splint 12 and a small splint 13. The upper end of the rod 3 14 has a group of spiral through holes 2 18, and the lower end has two groups of smooth through holes, which are upper smooth through holes 19 and lower smooth through holes 20. The rod 4 15 slides in the rod 3 14. The upper and lower ends of the rod 4 15 are respectively provided with a group of upper spiral through holes 21 and lower spiral through holes 22, and the upper spiral through holes 21 and the lower spiral through holes 22 are respectively provided with a group of upper spiral through holes 21 and the lower spiral through holes 22. A plurality of spiral through holes are arranged between the second and second rods 22, a group of smooth through holes 1 23 are opened at the upper end of the fourth rod 15, and screws 24 are penetrated in any group of threaded through holes between the third rod 14 and the fourth rod 15, an upper protruding cylindrical structure 25 is arranged at the upper end of the large clamping plate 12, and a ratchet structure 16 is arranged at the lower end thereof, the upper protruding cylindrical structure 25 passes through the upper smooth through hole 19 of the third rod 14 and is connected to the small clamping plate 13, and a crank handle 17 is arranged at the bottom end of the third rod 14;

[0068] The crank 17 includes a protruding cylindrical structure 1 27, which is installed at one end of the crank 17. A handle 28 and a protruding cylindrical structure 2 29 are installed at the other end of the crank 17. The protruding cylindrical structure 1 27 passes through the lower smooth through hole 1 20 and is connected to the rod 3 14.

[0069] The large splint 12 on the same side is connected by a cross bar, and the bottom of the cross bar is installed on the top of the rod 2 7.

[0070] The ratchet structure 16 includes a ratchet 26 and a pawl 30. The ratchet 26 is arranged in the ratchet structure 16. A connecting cylinder 31 is arranged 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 splint 12 through a rotating shaft. The pointed part of the pawl 30 contacts the outer tooth tip of the ratchet 26.

[0071] Specifically, the length of the swing arm can be changed to meet different sunshade or cold protection requirements by adjusting the screw 24 between the rod 3 14 and the rod 4 15. The screw 24 can be inserted through the spiral through hole 2 18 of the rod 3 14 and any spiral through hole of the rod 4 15 to adjust the length according to the actual situation of the vineyard to ensure that the sunshade material can cover the entire area.

[0072] When the angle of the sunshade or cold-proof material needs to be adjusted, the operator can manually rotate the crank 17. The rotation of the crank 17 drives the rod 3 14 to swing up and down through the connection between the protruding cylindrical structure and the smooth through hole, thereby controlling the moving direction and angle of the material. The crank 17 ensures unidirectional movement through the ratchet structure 16 to prevent the swing arm from rebounding, thereby enhancing the safety of operation.

[0073] The ratchet 26 and the pawl 30 cooperate to make the swing arm only move in one direction when shaking, and will not slide in the opposite direction due to the weight of the material or the 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 attached Fig. 9 -Attached Fig.10 , multiple groups of swing driven arms 4, each of which is installed on the ground through a column 2 and another telescopic column 1, and is connected to the swing driving arm 3 through a long stick 58, and swings synchronously with the movement of the driving arm to help coordinate the forward and backward swing of the device, so that the coverage of the sunshade or cold-proof material is more uniform;

[0075] The multiple groups of swing follower arms 4 each include two rods 5 34, and each of the two rods 5 34 is respectively arranged on both sides of the top of the column 2 or another telescopic column 1, and an upper smooth through hole 2 36 and a lower smooth through hole 2 37 are sequentially penetrated at the lower end of each rod 5 34, and a rod 6 35 is slidably arranged in each rod 5 34, and a smooth through hole 4 38 is penetrated at the top of the rod 6 35, the lower smooth through holes 1 20 on both sides and multiple lower smooth through holes 2 37 on the same side are connected by a long stick 1 58, and the smooth through holes 1 23 on both sides and multiple smooth through holes 4 38 on the same side are connected by a long stick 2 59.

[0076] A protruding cylindrical structure 39 is provided in the upper 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 cross bar, and the cross bar is installed on the top of the column 2 .

[0077] Specifically, each set of swing driven arms 4 is fixed on the ground through the column 2 to form 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 2 36 and a lower smooth through hole 2 37, and the sixth rod 35 is slidably installed in the fifth rod 34 to facilitate height adjustment. By adjusting the positions of the fifth rod 34 and the sixth rod 35, the length and angle of the swing driven arm 4 can be controlled.

[0078] The long stick 1 58 connects the lower smooth through hole 1 20 of the swing driving arm 3 with the lower smooth through hole 2 37 of the swing driven arm 4, so that the swing driving arm 3 and the swing driven arm 4 can 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 to achieve a coordinated covering effect.

[0079] At the same time, the long stick 2 59 connects the smooth through hole 1 23 of the swing driving arm 3 with the smooth through hole 4 38 of the swing driven arm 4, further ensuring the synchronous movement of the two, so that the sunshade or cold-proof material maintains a consistent height and angle when covering.

[0080] The large clamping plate 2 32 and the small clamping plate 2 33 are connected by the protruding cylindrical structure 3 39, and are connected to the top of the column 2 by a cross bar, which further enhances the overall stability of the swing driven arm 4. This design makes the swing driven arm 4 more stable during movement, and effectively reduces the shaking or uneven swing caused by external factors.

[0081] Please see attached Fig.11 -Attached Fig.15 , a retractable structure 5, which is arranged above a plurality of swing driven arms 4, is used for automatically retracting or unfolding sunshade or cold-proof materials.

[0082] The contraction structure includes a sliding rod 40, a pulley 1 45 and a rope 49. The bottom of the pulley 1 45 is set on a cross bar connected to the upper side of a group of swing driven arms 4. A pulley 2 46 and a pulley 3 47 are installed on the cross bar connected to the upper side of the other group of swing driven arms 4. The pulley 2 46 and the pulley 3 47 are symmetrically placed. A pulley housing 60 is set outside the telescopic column 1 on the same side. A pulley 48 is set inside the pulley housing 60. The rope 49 passes around the pulley 1 45 and the pulley 2 46. , pulley three 47 and pulley four 48, the sliding rod 40 is arranged above the multiple groups of swing driven arms 4, and a plurality of hollow cylinders two 52 are slid in sequence on the outer wall of the sliding rod 40, and the outer wall of one of the hollow cylinders two 52 is connected with a connecting component 42, and the connecting component 42 includes a hollow cylinder one 50, and the middle part of the hollow cylinder one 50 is fixed on the outer wall of the rope 49, the hollow cylinder one 50 and the hollow cylinder two 52 are connected by a connecting rod 51, and the bottoms of the plurality of hollow cylinders two 52 are connected by a connecting assembly.

[0083] The connecting assembly includes a sliding head 41, a rod seven 43 and a rod eight 44. The top of the sliding head 41 is installed at the bottom of the hollow cylinder two 52, and a cylinder 53 is installed at the bottom of the sliding head 41. The outer walls of the cylinders 53 on both sides are respectively provided with rod seven 43 rotating through smooth through holes five 54 and rod eight 44 rotating through smooth through holes seven 56. The outer walls of the multiple cylinders 53 in the middle are respectively provided with a group of rods seven 43 and rod eight 44 rotating through smooth through holes five 54 and smooth through holes seven 56. Two adjacent rods eight 44 and rod seven 43 are connected by protruding cylindrical structures four 57 and smooth through holes six 55.

[0084] Specifically, a sliding rod 40 is installed on the top of the device, and a plurality of hollow cylinders 2 52 are sequentially slidably arranged on the outer wall thereof. These hollow cylinders 2 52 are connected to the rod 7 43 and the rod 8 44 through the sliding head 41, and the stability of the entire contraction structure 5 is maintained through these components. When the pulley drives the rope 49 to move, sliding occurs between the hollow cylinder 2 52 and the sliding rod 40, thereby driving the contraction and expansion of the sunshade or cold-proof material.

[0085] Pulley 1 45 is mounted on a crossbar of one set of swing driven arms 4, and pulley 2 46 and pulley 3 47 are symmetrically mounted on a crossbar of another set of swing driven arms 4, forming a support structure of the pulley system. Pulley 48 cooperates with the motor to drive the rope 49 to go around between the pulleys, thereby controlling the movement of the sunshade or cold-proof material. The rope 49 goes around each pulley and transmits the movement to the hollow cylinder and the sliding head 41 through the connecting rod 51, thereby realizing the automatic contraction or expansion of the sunshade material.

[0086] The top of the sliding head 41 is connected to the hollow cylinder, and the bottom is rotatably connected to the rod 7 43 and the rod 8 44 through the cylinder 53. The combination of multiple sliding heads 41 and the rod 7 43 and the rod 8 44 ensures that the material on the sliding rod 40 can move smoothly within the entire device. Adjacent sliding components are connected through protruding cylindrical structures and smooth through holes to ensure the coordinated movement of each part and avoid unevenness of the material when it is contracted or expanded.
