Description

Technical Field

[0001] This utility model relates to the field of tea garden planting technology, specifically a frost-proof disturbance device for tea gardens. Background Technology

[0002] Tea gardens are agricultural areas where tea trees are planted and tea leaves are harvested. When planting tea seedlings, frost protection devices are needed to prevent low-temperature frost from damaging the tea trees.

[0003] A search revealed that the patent, CN213907757U, entitled "Utility Model of Intelligent Frost Protection Device for Mountain Apples," is installed around the orchard. Research and analysis revealed that although it meets the needs of intelligent orchard protection during use, and the system design is scientific and reasonable, effectively reducing frost losses, it also has the following drawbacks to some extent.

[0004] For example, if the device does not have a bottom ventilation function, it cannot pre-expel the cold air accumulated on the tea garden ground before the disturbance operation. After the device is started, it can only transport and mix the warm air at high altitude downwards, while the cold air remaining on the ground will continue to act on the tea plants, causing the sprouted buds and leaves to be damaged by intercellular freezing and protoplasmic dehydration, resulting in scorching or even large areas of withering. In order to solve the above technical problems, we have designed a tea garden anti-frost disturbance device. Utility Model Content

[0005] The purpose of this utility model is to provide a tea garden anti-frost disturbance device, which has the advantage of being able to pre-discharge the cold air accumulated on the tea garden ground before the disturbance operation, thus solving the problem that existing tea garden anti-frost disturbance devices cannot pre-discharge the cold air accumulated on the tea garden ground before the disturbance operation, resulting in the residual cold air on the ground continuing to act on the tea plants.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tea garden anti-frost disturbance device, comprising a rod body, the top of which is connected to a housing, a fan being fixedly connected through the front side of the housing, rectangular tubes being connected to the bottom sides, front side, and rear side of the rod body, and an exhaust hood being connected to the opposite end of each rectangular tube, a rotating cylinder being movably sleeved on the surface of the rod body via bearings, a rectangular plate being riveted to the right side of the rotating cylinder, and horizontal plates being riveted to the front and rear sides of the rectangular plate, a reduction motor being bolted to the right side of the front horizontal plate, the output end of the reduction motor passing through the front horizontal plate and being bolted to a rotating plate, a drive motor being bolted to the top of the rotating plate, the output end of the drive motor passing through the rotating plate and being bolted to a fan blade, a driven gear being fixedly sleeved on the top of the rotating cylinder surface, and a drive mechanism being riveted to the top of the right side of the rod body.

[0007] Preferably, the drive mechanism includes a fixed plate, the left side of which is riveted to the rod body, and a self-locking motor is bolted to the top of the fixed plate. The output end of the self-locking motor is bolted to a drive gear, and the left side of the drive gear meshes with a driven gear.

[0008] Preferably, a mounting plate is fixedly connected to the bottom of the rod, and a plurality of mounting holes are provided at the top edge of the mounting plate.

[0009] Preferably, a reinforcing plate is riveted to the right side of the rectangular plate, and the front and rear sides of the reinforcing plate are connected to the horizontal plate by bolts.

[0010] Preferably, a rotating rod is fixedly connected to the rear side of the rotating plate, and the rear end of the rotating rod passes through the rear horizontal plate and is connected to a brake disc by bolts. A brake adapted to the brake disc is connected to the rear side of the rear horizontal plate by bolts.

[0011] Preferably, the fan blades are located at the bottom of the horizontal plate, and the number of the exhaust hoods is four.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model has the advantage of bottom ventilation function through the cooperation of rod body, shell, fan, rectangular tube and air extraction hood.

[0016] Please see Figures 1-4 A frost-prevention and disturbance device for tea gardens includes a pole 1. The pole 1 has a hollow interior, serving as a cold air transport channel. Combined with a rectangular tube 4 and an extraction hood 5, it collects and conducts cold air upwards from the bottom, preventing cold air accumulation on the tea garden floor. A shell 2 is connected to the top of the pole 1, and a fan 3 is fixedly connected to the front of the shell 2. The fan 3 actively draws air from inside the shell 2, creating negative pressure within the pole 1 and rectangular tube 4. This draws the accumulated cold air from the tea garden floor through the extraction hood 5 and discharges it upwards to the atmosphere. Rectangular tubes 4 are connected to the bottom sides, front, and rear of the pole 1, with the opposite ends of each tube connected to the extraction hood 5. The ventilation system, consisting of rectangular tubes 4 and extraction hood 5, uses a funnel-shaped structure to further expand the cold air intake area and increase the amount of cold air collected per unit time. A rotating cylinder 6 is movably mounted on the surface of the pole 1 via bearings. This rotating cylinder 6, a rectangular plate, can rotate freely around the pole 1. 7 and subsequent components such as fan blade 12 provide rotational support. A rectangular plate 7 is riveted to the right side of the rotating cylinder 6. A horizontal plate 8 is riveted to both the front and rear sides of the rectangular plate 7. A geared motor 9 is bolted to the right side of the front horizontal plate 8. By setting the geared motor 9, the rotating plate 10 can be driven to rotate slowly and stably, and the tilt angle of the fan blade 12 can be precisely adjusted. The output end of the geared motor 9 passes through the front horizontal plate 8 and is bolted to the rotating plate 10. A drive motor 11 is bolted to the top of the rotating plate 10. By setting the drive motor 11, power can be provided for the high-speed rotation of the fan blade 12, which can drive the fan blade 12 to generate a stable and strong airflow, which delivers the warm air in the upper part of the tea garden downward to the surface of the tea seedlings and mixes with the residual cold air on the ground. The model of the drive motor 11 is a Y80M1-2 three-phase asynchronous motor. The output end of the drive motor 11 passes through the rotating plate 10 and is bolted to the fan blade 12. A driven gear 13 is fixedly sleeved on the top of the surface of the rotating cylinder 6. A drive mechanism 14 is riveted to the top of the right side of the rod 1.

[0017] Please see Figure 1 and Figure 3The drive mechanism 14 includes a fixed plate 141. The left side of the fixed plate 141 is riveted to the rod 1. The top of the fixed plate 141 is connected to a self-locking motor 142 by bolts. By setting the self-locking motor 142, the drive gear 143 can be driven to rotate clockwise or counterclockwise to realize the rotation angle adjustment of the fan blade 12. The output end of the self-locking motor 142 is connected to the drive gear 143 by bolts. The left side of the drive gear 143 meshes with the driven gear 13.

[0018] Please see Figure 1 The bottom of the rod 1 is fixedly connected to the mounting plate 15. By setting the mounting plate 15, the device can be fixed to the cement base surface of the tea garden ground by expansion bolts. Several mounting holes are opened at the top edge of the mounting plate 15.

[0019] Please see Figure 1 and Figure 4 A reinforcing plate 16 is riveted to the right side of the rectangular plate 7. By setting the reinforcing plate 16, the strength and stability of the connection between the horizontal plate 8 and the rectangular plate 7 can be greatly improved. The front and rear sides of the reinforcing plate 16 are connected to the horizontal plate 8 by bolts.

[0020] Please see Figure 3 A rotating rod 17 is fixedly connected to the rear side of the rotating plate 10. The rear end of the rotating rod 17 passes through the rear horizontal plate 8 and is connected to a brake disc 18 by bolts. A brake 19 adapted to the brake disc 18 is connected to the rear side of the rear horizontal plate 8 by bolts. By setting the brake disc 18 and the brake 19, an electromagnetic braking method is adopted, which has a fast response speed. The braking and release can be precisely controlled by an external controller to achieve rapid fixation of the tilt angle of the fan blade 12.

[0021] Please see Figure 1 The fan blade 12 is located at the bottom of the horizontal plate 8, and there are four exhaust hoods 5.

[0022] In use, the device is installed in the tea garden via mounting plate 15. Then, an external controller and power supply are connected. During defrosting, the external controller operates the fan 3, which draws air from inside the casing 2. Cold air from the bottom of the tea garden enters the rod 1 through the extraction hood 5 and rectangular tube 4. Finally, the cold air from the bottom of the tea garden is discharged to the top of the tea garden by the fan 3. Subsequently, the external controller controls the drive motor 11 to operate. The output of the drive motor 11 drives the fan blades 12 to rotate at high speed. The fan blades 12 push the high-temperature air from the upper part of the tea garden to the surface of the tea seedlings. When the position of the fan blades 12 needs to be adjusted, [further adjustments can be made]. The peripheral controller controls the self-locking motor 142, the driving gear 143 drives the driven gear 13 to rotate, the driven gear 13 drives the rotating drum 6 and the rectangular plate 7 to rotate, and the rectangular plate 7 drives the fan blade 12 to rotate, thereby adjusting the position of the fan blade 12 and increasing its disturbance range. When it is necessary to adjust the tilt angle of the fan blade 12, the peripheral controller controls the brake 19 to release the limit on the brake disc 18, and then the peripheral controller controls the geared motor 9 to run. The output end of the geared motor 9 drives the rotating plate 10 and the drive motor 11 to rotate, thereby adjusting the tilt angle of the fan blade 12 and making its disturbance range farther.

[0023] In summary, this tea garden frost prevention disturbance device, through the cooperation of rod 1, shell 2, fan 3, rectangular tube 4 and air extraction hood 5, solves the problem that existing tea garden frost prevention disturbance devices cannot pre-expel the cold air accumulated on the tea garden ground before disturbance operations, resulting in the residual cold air on the ground continuing to act on the tea plants.
