For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0059] The embodiments of the present invention are described in detail below.

[0060] Example

[0061] See also Figure 1 to Figure 9 The present embodiment provides a device for protecting fruit trees from rain and preventing fruit cracking, comprising a bracket 1, a conical cap 2, an arc-shaped rod 3, a support arm 4, a support frame 5, a rainproof film 6 and a driving mechanism.

[0062] The support 1 is Y-shaped and can be fixed near a fruit tree (sweet cherry).

[0063] The conical cap 2 is connected to the top of the bracket 1. The conical cap 2 is in the shape of a polygonal pyramid or a cone.

[0064] One end of the arc rod 3 is connected to the outer wall of the conical cap 2, and the other end extends upward along an arc track. A plurality of (such as two or four) arc rods 3 are distributed at intervals along the circumference of the conical cap 2, and each arc rod 3 is concentric.

[0065] A sliding ring 41 is provided on the sliding sleeve of the arc-shaped rod 3 , and one end of the support arm 4 is slidably connected to the arc-shaped rod 3 through the sliding ring 41 .

[0066] The support frame 5 is quadrilateral. A plurality of support frames 5 are fixed on the support arm 4 at intervals. The angle α between the support frame 5 and the support arm 4 is an acute angle, and the support frame 5 is tilted relative to the support arm 4; the support frames 5 are parallel to each other. The support arm 4 can be connected to the middle or end of one side of the support frame 5.

[0067] The rainproof film 6 is made of transparent material and is arranged on the inner side of the support frame 5. The projections of any two adjacent rainproof films 6 on the same arm 4 on the ground partially overlap. The tension of the rainproof film 6 is adjustable.

[0068] The driving mechanism is used to make the slip ring 41 slide along the arc rod 3 so that the support arm 4 is in the first working position or the second working position, and the second working position is located above the first working position; wherein, the first working position is used for rain protection (suitable for rainy season), and the second working position is a commonly used position and does not have a rain protection function.

[0069] like Figure 1As shown, when the support arm 4 is in the first working position, the support arm 4 droops, and a first flow channel 61 obliquely upward is formed between the rainproof membranes 6 on each support frame 5. In this way, on the one hand, it can ensure that rainwater does not directly fall on the fruit or near the roots of the fruit trees during the rainy season (heavy rainfall) to avoid fruit cracking; on the other hand, it can not only reduce the windward area of ​​the rainproof membrane 6 to reduce the impact of strong winds on the stability of the entire device (or in other words, the entire device has strong wind resistance), but also form an upward airflow near the fruit trees (when there is wind), speeding up the evaporation of rainwater near the bottom of the fruit trees after the rain (although rainproof measures are taken above the fruit trees, when the rain is heavy, the nearby rainwater will still flow to the vicinity of the roots of the fruit trees). Figure 2 As shown, when the arm 4 is in the second working position, the arm 4 rises, and a second flow passage 62 obliquely downward is formed between the rainproof films 6 on each support frame 5. In this way, on the one hand, the windward area of ​​the rainproof film 6 can be reduced, and the influence of strong wind on the stability of the entire device can be reduced (or the wind resistance of the entire device is strong); on the other hand, the rising arm 4 expands the coverage area of ​​the rainproof film 6 (the projection of the rainproof film 6 on the ground is increased), and the rainwater collected nearby can be gathered near the fruit trees when it rains lightly during occasional droughts, thereby improving the drought resistance of the fruit trees. In addition, the adjustable tension of the rainproof film 6 has the following advantages: when the arm 4 is in the second working position, on the one hand, in the case of low wind, by reducing the tension of the rainproof film 6, the rainproof film 6 can be vibrated and sounded, which has the effect of driving away birds; on the other hand, in the case of strong wind, by increasing the tension of the rainproof film 6, the vibration of the rainproof film 6 can be weakened, thereby avoiding resonance of the entire device and affecting the stability of the entire device.

[0070] From the foregoing content, it can be seen that when the support arm 4 is in the first working position or the second working position, the fruit tree shelter from rain and fruit cracking prevention device can play a corresponding role while ensuring that the fruit trees can receive sunlight normally; after installation, the fruit tree shelter from rain and fruit cracking prevention device does not need to be disassembled, only the position of the support arm 4 needs to be adjusted, which is very convenient to use.

[0071] A limit block 31 is provided on the arc rod 3. When the support arm 4 is in the first working position, the limit block 31 contacts the slip ring 41 to prevent the slip ring 41 from moving further downward.

[0072] In order to improve the stability of the arc-shaped rod 3 , an extension column 21 is connected to the top of the conical cap 2 , and the extension column 21 is connected to the arc-shaped rod 3 via a reinforcing rod 22 .

[0073] The driving mechanism includes a driving motor 71, a winding wheel 72 and a winding rope 73 (by Figure 1 (denoted by double-dotted lines).

[0074] The driving motor 71 is installed in the conical cap 2 , and the conical cap 2 plays a protective role for the driving motor 71 .

[0075] The winding wheel 72 is drivingly connected to the output shaft of the driving motor 71 .

[0076] One end of the take-up rope 73 is fixed to the take-up wheel 72 , and the other end is connected to the slip ring 41 . A wire passage 211 is provided on the upper portion of the extension column 21 , and the take-up rope 73 passes through the wire passage 211 .

[0077] When the driving motor 71 rotates forward, the winding wheel 72 drives the slip ring 41 to move upward through the winding rope 73, so that the support arm 4 is in the second working position; when the driving motor 71 rotates reversely, the winding wheel 72 drives the slip ring 41 to move upward through the winding rope 73, and under the action of the deadweight of the support arm 4 and other components, the support arm 4 drives the slip ring 41 to move, and the support arm 4 can move to the first working position.

[0078] In order to facilitate the adjustment of the tension of the rainproof film 6, a sliding rod 51 is slidably connected in the support frame 5. One end of the rainproof film 6 is connected to one side of the support frame 5, and the other end is connected to the sliding rod 51. The tension of the rainproof film 6 can be adjusted by sliding the sliding rod 51.

[0079] This embodiment also includes a tension rope 81 (by Figure 1 The number of slide bars 51 matches the number of support frames 5. If there are multiple support frames 5 on the same arm 4, there will be multiple slide bars 51. A through hole 52 is opened on one side of each support frame 5. After the tension rope 81 passes through the through hole 52 and penetrates one side of each support frame 5, it is connected to the middle part of each slide bar 51, so that each slide bar 51 is connected in series in sequence. Figure 1 As shown ( Figure 1 The middle arrow is used to indicate the moving direction of the slide bar 51 when the rainproof film 6 is tensioned). By pulling the upper end of the tensioning rope 81, each slide bar 51 can be moved synchronously, thereby adjusting the tension of the rainproof film 6.

[0080] Furthermore, in order to facilitate pulling the upper end of the tension rope 81 , the present embodiment further includes a pneumatic member 82 , a transmission shaft 83 , a roller 84 and a movable block 85 .

[0081] The pneumatic member 82 is rotatably connected to the top of the extension column 21 via a transmission shaft 83 .

[0082] The transmission shaft 83 is coaxially arranged with the extension column 21 .

[0083] The roller 84 is mounted on the lower end of the transmission shaft 83 .

[0084] A slide groove 86 is provided in the extension column 21, and the movable block 85 is slidably fitted in the slide groove 86; the roller 84 is in rolling contact with the movable block 85; the upper end of the tensioning rope 81 passes through the side wall of the extension column 21 and is connected to the movable block 85, and the extension line of the upper end of the tensioning rope 81 passes through the center of the arc rod 3.

[0085] Since the roller 84 and the movable block 85 are in rolling contact, there is rolling friction resistance between the two. The wind can drive the pneumatic member 82 to drive the roller 84 to rotate. In the process of the pneumatic member 82 driven by the wind to drive the roller 84 to rotate, the rotation speed of the pneumatic member 82 is relatively low at the beginning, and the roller 84 cannot overcome the rolling friction resistance between it and the movable block 85. The movable block 85 will move with the roller 84 to initially tighten the rainproof film 6; then the pneumatic member 82 rotates at a faster speed, so that the roller 84 overcomes the rolling friction resistance between it and the movable block 85. Under the influence of the rolling friction resistance, the movable block 85 has a tendency to drive the tension rope 81 to continue to move, and transmits a relatively stable traction force to the slide bar 51 through the tension rope 81, so that the tension of the rainproof film 6 remains stable. It can be understood that as the wind continues to increase, the rolling friction resistance will not increase all the time, and the rolling friction resistance is a value that tends to be stable. In this way, it can avoid the rainproof film 6 from being torn due to excessive traction of the tension rope 81.

[0086] In addition, since the extension line of the upper end of the tension rope 81 passes through the center of the arc rod 3, the traction force of the tension rope 81 on the slide bar 51 will not change much when the position of the support arm 4 is adjusted, which is conducive to maintaining the current tension of the rainproof film 6. It can be understood that in order to ensure the stability of the traction force of the tension rope 81 on the slide bar 51 during the process of adjusting the position of the support arm 4, a strip hole for avoiding the tension rope 81 should be opened on the side wall of the extension column 21.

[0087] Furthermore, an elastic member 87 is provided in the slide groove 86, and the elastic member 87 is used to increase the rolling friction resistance between the roller 84 and the movable block 85, so that when the wind force is small, the wind force is insufficient to drive the pneumatic member 82 to drive the roller 84 to rotate, and the tensioning rope 81 is not triggered. At this time, the rainproof film 6 is in a relatively relaxed state and can vibrate and make sounds to drive away birds.

[0088] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
