[0002] Sweet cherries have an oval shape, bright red color, and thick flesh, and are excellent varieties among cherries. Different planting times of sweet cherries have different requirements for water. During the harvest season, if it rains, excessive water will cause the sweet cherries to crack. At this time, a rain shelter device is needed to cover the sweet cherries to reduce fruit cracking.

[0003] The document with the publication number CN118661584A discloses a device for preventing sweet cherry fruit cracking, which includes a plurality of "n"-shaped support frames arranged in sequence from front to back and from left to right. A folding rain shelter is installed at the upper end of the support frame, and a power component for driving the folding rain shelter to open and close is provided on the support frame. The folding rain shelter includes several mounting frames, connecting rods, rainproof cloth, extension frames, first folding strips, and second folding strips. The mounting frames are arranged at the upper end of the support frame from front to back, and the lower end of the mounting frame is slidably connected to the support frame. The power component drives the connecting rod to slide back and forth. There are two extension frames, which are respectively installed on the front mounting frame and the rear mounting frame. The rainproof cloth covers the mounting frames and the extension frames. In this invention, the folding rain shelter is arranged in the air through the "n"-shaped support frame, and is used for rain shelter and hail protection after being unfolded. The contact between the support frame and the ground is less, reducing the occupation of space, facilitating the use of automated machinery for labor, and reducing the use of manpower and material resources. However, in the actual application process, common rain shelter devices are mostly directly inserted into the ground, and the support lacks effective support, with poor wind resistance and stability on rainy days, and is easily blown down by the wind on rainy days, affecting the actual rain shelter effect. Therefore, certain improvements are needed. Summary of the Invention

[0027] 1. In the present invention, by providing a stabilizing component, the limiting relationship between the limiting rack and the limiting gear is released, enabling the rotating pipe to rotate freely. The rotating pipe drives the supporting spines to rotate through the sliding groove, mounting bracket, rotating box, and moving lead screw, causing the angle of the supporting spines to change and the supporting spines to rotate out of the through groove. Subsequently, the staff drives the supporting spines to move to one side and penetrate into the ground through the rotating shaft, rotating shaft, rotating rod, sleeve, first bevel gear, second bevel gear, moving lead screw, and fixed slide rod, changing the moving stroke of the supporting spines and causing the supporting spines to be obliquely inserted into the ground in an inclined manner. This improves the connection tightness between the device and the ground, provides an oblique support for the moving frame and the base plate, enhances the stability of the device, improves the device's resistance to wind and rain and anti-tipping ability, extends the service life of the device, and thus reduces the impact of rain on cherries.

[0028] 2. In the present invention, by providing an unfolding and folding component, the adjusting lead screw moves through the lead screw seat, moving frame, and support. At the same time, the moving frame drives multiple moving frames to expand equidistantly to one side through the linkage effect between the third connecting rod and multiple second connecting rods, thereby causing the multiple moving frames and the support to move and the rain shelter film to unfold to a suitable position. This can meet the rain shelter requirements of cherry trees with different planting quantities, making the rain shelter film applicable to different application scenarios and improving the overall applicability of the device.

[0029] 3. In the present invention, by providing a wind resistance component, the small fan discharges air flow through the connecting pipe and the air outlet. The ejected air flow blows the rain shelter film from the inside, causing the rain shelter film to fully expand and fill, thereby enhancing the relative impact resistance of the rain shelter film, reducing the influence of rainy-day wind on the rain shelter film, preventing the rain shelter film from being blown away, and improving the overall rain shelter ability of the device.

A moving lead screw 718 is rotatably connected inside the rotating tube 703. One end of the outer surface of the moving lead screw 718 extends outside the rotating box 708 and is threadedly connected with a support spiked nail 709, which is used to cooperate with the rotation of the moving lead screw 718 to adjust its own moving stroke and penetrate into the ground for support. Inside the rotating tube 703, a rotating rod 713 is rotatably connected through a rotating shaft. A plurality of sleeves 715 distributed in a linear array are sleeved on the outer surface of the rotating rod 713. The outer surface of the sleeve 715 is rotatably connected with a mounting frame 719. Both sides of the mounting frame 719 are connected with the inner wall of the rotating box 708. A sliding groove 710 is opened at the bottom of the rotating tube 703. The mounting frame 719 is slidably connected in the sliding groove 710. The moving lead screw 718 is rotatably connected with the mounting frame 719. One end of the moving lead screw 718 is connected with a second bevel gear 716.

One end of the rotating shaft extends outside the rotating tube 703 and is connected with a rotating shaft 702. A limiting hole 712 is opened on the outer surface of the rotating shaft 702. A fixing ring 711 is connected to one side of the rotating tube 703. A limiting block is connected to the inner peripheral side of the fixing ring 711, and the limiting block is clamped with the limiting hole 712. The limiting block is a flexible plastic block. The inner wall of the sleeve 715 and the cross-sectional shape of the rotating rod 713 are both regular hexagons. Both sides of the bottom of the rotating box 708 are connected with fixed sliding rods 717. The two fixed sliding rods 717 are arranged symmetrically in a mirror image on both sides of the moving lead screw 718. Circular holes are opened on both sides of the top of the support spiked nail 709. The fixed sliding rods 717 are slidably connected in the circular holes.

[0047] The implementation method is specifically as follows: By setting the stabilizing component 7, by releasing the limiting relationship between the limiting rack 704 and the limiting gear 701, the rotating tube 703 can rotate freely. The rotating tube 703 drives the supporting spike 709 to rotate through the sliding groove 710, the mounting bracket 719, the rotating box 708 and the moving lead screw 718, so that the angle of the supporting spike 709 changes and the supporting spike 709 rotates out of the through groove 10. After that, the staff drives the supporting spike 709 to move to one side and penetrate into the ground through the rotating shaft 702, the rotating shaft, the rotating rod 713, the sleeve 715, the first bevel gear 714, the second bevel gear 716, the moving lead screw 718 and the fixed slide bar 717, so that the moving stroke of the supporting spike 709 changes, and the supporting spike 709 is obliquely inserted into the ground in an inclined manner, thereby improving the connection tightness between the device and the ground, providing an oblique support for the moving frame 9 and the base plate 2, improving the stability of the device, enhancing the wind and rain resistance and anti-tipping ability of the device, and prolonging the service life of the device.

[0048] The unfolding and folding component 8 includes a plurality of second connecting rods 802 arranged in a linear array. Two adjacent second connecting rods 802 are hinged to each other through a first pin shaft. One end of the second connecting rod 802 located on the outermost side is hinged to a third connecting rod 804. One side of the third connecting rod 804 and the plurality of second connecting rods 802 are all rotatably connected to one side of the moving frame 9. One end of the second connecting rod 802 far from the end of the third connecting rod 804 is hinged to a first connecting rod 801 through a second pin shaft. The other end of the first connecting rod 801 is hinged to a hinge seat 803. One side of the hinge seat 803 is connected to one side of the fixing plate 1. Sliders 809 are connected to both sides of the bottom of the moving frame 9. Sliding grooves 805 are formed at the top of the base plate 2. Limiting grooves 806 are formed on both sides of the inner wall of the sliding groove 805. The sliders 809 are slidably connected to the limiting grooves 806. An adjusting lead screw 808 is rotatably connected in the sliding groove 805. A lead screw seat 807 is threadedly connected to the outer surface of the adjusting lead screw 808. The top of the lead screw seat 807 is connected to the bottom of the outermost moving frame 9.

[0049] The implementation method is specifically as follows: By setting the unfolding and folding component 8, the adjusting lead screw 808 moves through the lead screw seat 807, the moving frame 9 and the bracket 5. At the same time, the moving frame 9 drives a plurality of moving frames 9 to unfold equidistantly to one side through the linkage effect between the third connecting rod 804 and the plurality of second connecting rods 802, so that the plurality of moving frames 9 and the bracket 5 move, and the rain shelter film 6 is unfolded to a suitable position, so as to meet the rain shelter requirements of cherry trees with different planting quantities, and the rain shelter film 6 can be applied to different application scenarios.

[0050] The wind-resistant component 4 includes two symmetrically arranged small wind turbines 401. The small wind turbines 401 are connected to one side of the movable frame 9. One side of the small wind turbine 401 is communicated with a connecting pipe 402. A hollow cavity is formed inside the support 5. The other end of the connecting pipe 402 far from the small wind turbine 401 is communicated with the hollow cavity. A plurality of air outlets 403 are provided on both sides of the support 5 for blowing the rainproof film 6 from the inside to make it fully inflated. The plurality of air outlets 403 are arranged in a semi-circular array, and the cross-sectional shape of the air outlet 403 is conical.

[0051] The specific implementation method is as follows: By setting the wind-resistant component 4, the small wind turbines 401 discharge air flow through the connecting pipe 402 and the air outlets 403. The ejected air flow will blow the rainproof film 6 from the inside and make the rainproof film 6 fully inflated, so as to enhance the relative impact resistance of the rainproof film 6, reduce the influence of the wind force in rainy days on the rainproof film 6, and prevent the rainproof film 6 from being blown away.

[0052] Working principle: During use, the staff installs the device in the cherry orchard through external equipment. During installation, the staff places the base plate 2 on the ground and makes the stabilizing spikes 3 penetrate into the ground to complete the preliminary installation of the device.

[0053] After that, the staff adjusts the actual extension distance of the device according to the actual situation. The staff rotates the handles on both sides, and the handles drive the adjustment lead screw 808 to rotate. The adjustment lead screw 808 drives the lead screw seat 807 to move in the chute 805. The lead screw seat 807 drives the movable frame 9 at the top to move. The two movable frames 9 drive the support 5 to move. During this process, the movable frame 9 drives the second link 802 to move through the third link 804, so that the second link 802 rotates around its own central position. The plurality of second links 802 drive the plurality of movable frames 9 to expand equidistantly to one side through the linkage effect between them.

[0054] After completing the adjustment of the length of the rain shelter film 6, the staff pulls up the sliding rod 707. The sliding rod 707 drives the limit rack 704 to move upward, causing the limit rack 704 to separate from the limit gear 701, and the limit of the limit gear 701 by the limit rack 704 is released. At this time, the staff rotates the rotating tube 703. The rotating tube 703 drives the sliding groove 710 to rotate. The sliding groove 710 drives the mounting bracket 719 to rotate. The mounting bracket 719 drives the rotating box 708 to rotate. The rotating box 708 cooperates with the moving lead screw 718 to drive the support spike 709 to rotate, causing the angle of the support spike 709 to change and the support spike 709 to rotate out of the through groove 10. Then, the staff releases the sliding rod 707. The sliding rod 707 makes a reset movement driven by the reset spring 705. The sliding rod 707 drives the limit rack 704 to move downward, and the limit rack 704 re-limits the limit gear 701 to prevent the rotating tube 703 from rotating. Then, the staff rotates the rotating shaft 702. The rotating shaft 702 drives the rotating rod 713 to rotate through the rotating shaft. The rotating rod 713 drives the sleeve 715 to rotate. The sleeve 715 drives the first bevel gear 714 to rotate. The first bevel gear 714 drives the second bevel gear 716 to rotate. The second bevel gear 716 drives the moving lead screw 718 to rotate. The moving lead screw 718 cooperates with the fixed sliding rod 717 to drive the support spike 709 to move to one side and penetrate into the ground, strengthening the connection effect with the ground.

[0055] In the face of rainy days, the small fan 401 starts. The small fan 401 conveys air into the connecting pipe 402, and makes the air form an air flow and discharge through the hollow cavity and the air outlet 403. The ejected air flow blows the rain shelter film 6 from the inside, and makes the rain shelter film 6 fully expand and fill, improving its wind resistance.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
