Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a device for protecting agricultural plants from wind and sand. Background Technology

[0002] Crop farming is a major component of agriculture, a social production sector that utilizes the life functions of plants to obtain food, non-staple foods, feed, and industrial raw materials through artificial cultivation.

[0003] In the northwest region, crops are often grown in greenhouses to protect them from sandstorms. However, greenhouse cultivation affects the amount of sunlight the plants receive, and because the northwest region receives little rainfall, greenhouse cultivation cannot make full use of rainwater during rainy weather. Utility Model Content

[0004] The present invention addresses the problem of providing an agricultural plant protection and sand-proof device. It solves the technical problem that when crops are grown in the Northwest region, greenhouse cultivation is often used to resist the impact of sandstorms. Greenhouse cultivation affects the light exposure of the plants, and at the same time, due to the low rainfall in the Northwest region, greenhouse cultivation cannot make full use of rainwater during rainy weather.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An agricultural plant protection and windbreak device comprises two parallel bases, a first base and a second base. Inner arc-shaped frames are installed on the inner sides of the first and second bases, and outer arc-shaped frames are installed on the outer top surfaces of the first and second bases. Shaft seats are installed at the center of both ends of the first and second bases. A rotating shaft is rotatably mounted between the two shaft seats, and rotating arms are installed at both ends of the rotating shaft. A connecting rod is installed between the two rotating arms, and the inner and outer arc-shaped frames of the connecting rod slide against each other. An inner cavity is formed within the first base, and a rotating shaft is rotatably mounted within the inner cavity. A windbreak and sand-proof membrane is wound around the rotating shaft and connected to the connecting rod.

[0007] Preferably, a first motor is mounted on the outer side of one of the bearing seats, and the output end of the first motor is connected to the rotating shaft.

[0008] Preferably, a second motor is mounted on the outside of the first base, and the second motor is connected to the shaft.

[0009] Preferably, both the first base and the second base are provided with adjustment grooves, and the bottom sides of both ends of the outer arc frame are provided with sliding seats, which are located in the adjustment grooves.

[0010] Preferably, the adjusting groove is equipped with a threaded rod and several guide rods, the threaded rod is threadedly connected to the slide block, and the slide block is slidably connected to the guide rods.

[0011] Preferably, a third motor is installed at the top center of both the first base and the second base, and the output end of the third motor is connected to the threaded rod.

[0012] Preferably, the components include a first base, a second base, an inner arc frame, an outer arc frame, a bearing seat, a rotating shaft, a rotating arm, a connecting rod, an inner cavity, a rotating shaft, a windproof sand membrane, a first motor, a second motor, an adjusting groove, a third motor, a threaded rod, and a slide.

[0013] The beneficial effects of this utility model are as follows: the first motor drives the connecting rod to move between the inner arc frame and the outer arc frame, which makes it easy to pull the windproof sand membrane wound on the shaft out of the inner cavity and lay it on the outside of the inner arc frame. The moving outer arc frame clamps the windproof sand membrane between the inner arc frame and the outer arc frame, thereby achieving a reinforced connection of the windproof sand membrane, which helps to resist the impact of wind and sand on the plant. At the same time, in non-wind and sand weather, it ensures that the plant can grow in the open air. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-3An agricultural plant protection and windbreak device comprises two parallel first bases 1 and second bases 2. An inner arc-shaped frame 3 is installed inside the first bases 1 and second bases 2, and an outer arc-shaped frame 4 is installed on the top outer side of the first bases 1 and second bases 2. A bearing 5 is installed at the center of both ends of the first bases 1 and second bases 2. A rotating shaft 6 is rotatably mounted between two bearing seats 5. Rotating arms 7 are mounted at both ends of the rotating shaft 6. A connecting rod 8 is mounted between the two rotating arms 7. The connecting rod 8 slides between the inner arc frame 3 and the outer arc frame 4. A first motor 12 is mounted on the outside of one of the bearing seats 5. The output end of the first motor 12 is connected to the rotating shaft 6. The first motor 12 drives the connecting rod 8 to move between the inner arc frame 3 and the outer arc frame 4, which facilitates the pulling out of the inner cavity 9 of the windproof sand membrane 11 wound on the winding shaft 10 and laying it on the outside of the inner arc frame 3. An inner cavity 9 is opened in the first base 1. The winding shaft 10 is rotatably mounted in the inner cavity 9. The windproof sand membrane 11 is wound on the winding shaft 10 and connected to the connecting rod 8. A second motor 13 is mounted on the outside of the first base 1 and connected to the winding shaft 10. The second motor 13 drives the winding shaft 10 to rotate, winding the windproof sand membrane 11 onto the winding shaft 10 and storing it in the inner cavity 9.

[0022] Both the first base 1 and the second base 2 have adjustment grooves 14. The bottom sides of both ends of the outer arc frame 4 are provided with slides 17, and the slides 17 are located in the adjustment grooves 14. The adjustment grooves 14 are equipped with threaded rods 16 and several guide rods. The threaded rods 16 are threadedly connected to the slides 17, and the slides 17 are slidably connected to the guide rods. The top middle of the first base 1 and the second base 2 are both equipped with third motors 15, and the output end of the third motors 15 is connected to the threaded rods 16. The operation of the third motors 15 drives the threaded rods 16 to rotate, which in turn drives the threaded slides 17 to rise and fall along the guide rods. When the outer arc frame 4 moves down, it is convenient to clamp the windproof sand membrane 11 between the inner arc frame 3 and the outer arc frame 4. When the outer arc frame 4 moves up, it is convenient to perform subsequent winding operations on the windproof sand membrane 11.

[0023] Working principle: In windy and sandy weather, the first motor 12 drives the rotating shaft 6 to rotate, thereby rotating the rotating arm 7 and the connecting rod 8. The connecting rod 8, located on the first base 1, is rotated to the second base 2. During the rotation, the windproof sand membrane 11, which is wound on the shaft 10, is pulled out from the inner cavity 9 and laid on the outside of the inner arc frame 3. The third motor 15 drives the threaded rod 16 to rotate, thereby driving the threaded sliding block 17 to move down along the guide rod. At this time, the outer arc frame 4 moves down, clamping the windproof sand membrane 11 between the inner arc frame 3 and the outer arc frame 4. When the wind and sand subside, the outer arc frame 4 moves up, the first motor 12 rotates the connecting rod 8 to its original position, and at the same time, the second motor 13 drives the shaft 10 to rotate, winding the windproof sand membrane 11 onto the shaft 10 and storing it in the inner cavity 9.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
