[0002] Agronomy refers to the traditional discipline in the field of agricultural science, with the primary responsibility of solving the problems of "food and clothing" for mankind. With the continuous acceleration of the innovation speed of agricultural science and technology, agronomy is showing vigorous vitality while maintaining its traditional characteristics. During the process of planting and researching plants, relevant workers often use agronomic plant protection devices to prevent plants from being pecked by birds outdoors.

[0003] According to a publicly announced agronomic plant protection device (publication number: CN216164770U), in the above application, the electric push rod in the middle of the bottom surface of the U-shaped fixing frame drives the cooperation between the spiral curve groove in the middle of the circumferential outer wall of the driving column, the guide post on the upper side of the right part of the inner wall of the guide sleeve circumference, and the limiting sleeve on the lower side of the circumferential outer wall of the driving column, so that the model can rotate while moving up and down and is always in an active state.

[0004] However, during the actual use of the above equipment, the rotation of the fan constantly knocks on the shell to drive away the birds. However, the single driving sound for a long time is easy for the birds to get used to, resulting in a weakened driving effect and allowing the birds to damage the plants; in view of this, we have proposed an adjustable agronomic plant protection device.

[0015] 1. For this adjustable agricultural plant protection device, by providing a protection mechanism, the fan rod is fixedly installed on the surface of the fixed rod. The fan rod rotates under the action of wind force to drive the fixed rod to rotate. Then, the knocking rod on the fixed rod drives the knocking ball to continuously knock the housing, making a sound to drive away birds. At the same time, the contact ball on the knocking rod continuously contacts different types of limiting balls on the protective ring, making the knocking rod move more stably. Under the action of the moving block and the stretching spring, the knocking rod makes a reciprocating motion on the surface of the limiting rod, changing the vertical position of the knocking rod, making different sounds to better drive away birds and better protect plants.

[0016] 2. The adjustable agricultural plant protection device is provided with a speed reduction mechanism.

[0024] In an embodiment of the present utility model, the fixed rod 301 is movably connected to the upper surface of the support plate 7. A moving groove 302 is formed in the arc surface of the fixed rod 301. A limiting rod 303 is fixedly installed on the inner wall of the moving groove 302. A stretching spring 304 is fixedly connected to the inner wall of the moving groove 302. One end of the stretching spring 304 far from the inner wall of the moving groove 302 is fixedly connected to a moving block 305. A knocking rod 306 is fixedly connected to the surface of the moving block 305. A contact ball 307 is fixedly installed on the arc surface of the knocking rod 306. A knocking ball 308 is fixedly installed at the end of the knocking rod 306. A protective ring 309 is fixedly installed on the upper surface of the support plate 7. A limiting ball 310 is fixedly installed on the surface of the protective ring 309.

[0025] In addition, the speed reduction mechanism 4 includes a speed reduction groove 401. The speed reduction groove 401 is formed in the surface of the fixed rod 301. An activity groove 403 is formed in the inner wall of the protective ring 309. A telescopic spring 404 is fixedly connected to the inner wall of the activity groove 403. One end of the telescopic spring 404 far from the inner wall of the activity groove 403 is fixedly installed with a speed reduction ball 402. The opening radian of the speed reduction groove 401 is adapted to the radian of the speed reduction ball 402. The number of the speed reduction grooves 401 is set to be several. The several speed reduction grooves 401 are arranged in a circumferential array on the surface of the fixed rod 301 to slow down the rotation of the fixed rod 301 to a certain extent and protect the whole device.

[0026] In an embodiment of the present utility model, the number of the limiting balls 310 is set to be three groups. The three groups of limiting balls 310 are fixedly installed on the surface of the protective ring 309 in a circumferential array. At the same time, each group of limiting balls 310 includes three spheres with different diameters, so that the contact ball 307 contacts the limiting balls 310 of different sizes to drive the knocking rod 306 to move up and down, and the positions of knocking on the shell 9 are different, and the sounds emitted are different. The cross-sectional shape of the moving block 305 is adapted to the cross-sectional shape of the moving groove 302. The moving grooves 302 are arranged in a mirror image on the surface of the fixed rod 301. The diameter of the speed reduction ball 402 is adapted to the diameter of the activity groove 403. The number of the activity grooves 403 is set to be multiple groups. Each group of activity grooves 403 has three. The multiple groups of activity grooves 403 are arranged in a circumferential array on the inner wall of the protective ring 309. The multiple groups of speed reduction balls 402 slow down the rotation of the fixed rod 301 stably, prevent the rotation speed of the fixed rod 301 from being too fast due to excessive wind force. At the same time, the inner diameter of the inner wall of the protective ring 309 is adapted to the diameter of the fixed rod 301. The protective ring 309 is sleeved on the surface of the fixed rod 301 and has a certain supporting effect on the fixed rod 301.

[0027] In the present utility model, during use, the fan rod 10 is fixedly installed on the surface of the fixed rod 301. The fan rod 10 rotates under the action of wind force, driving the fixed rod 301 to rotate. Furthermore, the knocking rod 306 on the fixed rod 301 drives the knocking ball 308 to continuously knock on the housing 9, emitting sounds to drive away birds. At the same time, the contact ball 307 on the knocking rod 306 continuously contacts different types of limiting balls 310 on the protection ring 309, making the movement of the knocking rod 306 more stable. Under the action of the moving block 305 and the stretching spring 304, the knocking rod 306 performs reciprocating motion on the surface of the limiting rod 303, changing the vertical position of the knocking rod 306, emitting different sounds to better drive away birds and better protect plants.

[0028] Furthermore, during the rotation of the fan, the speed reduction groove 401 on the fixed rod 301 continuously contacts the speed reduction ball 402 on the protection ring 309. The speed reduction ball 402 continuously performs reciprocating movement inside the movable groove 403 under the action of the telescopic spring 404, having a speed reduction effect on the rotation of the fixed rod 301, preventing the knocking rod 306 from rotating too fast in case of strong wind, damaging the mechanism, extending the service life of the device, better driving away birds and thus protecting plants. Place the base 1 on the ground and fix it with the ground nail 2. Adjust the length of the adjusting rod 5 and fix it through the fixing hole on the fixing block 6 fixed on the adjusting rod 5, and adjust the height of the support plate 7 to protect plants at different heights.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
