Description

Technical Field

[0001] This utility model relates to the field of garden equipment technology, specifically a cooling nozzle for autumn foliage trees. Background Technology

[0002] Autumn-colored foliage trees refer to tree species whose leaves are green during the growing season, but change to a variety of colors such as red, orange, yellow, and purple in autumn or after frost. Major species include sweetgum, tallow tree, and ginkgo. Autumn temperature fluctuations are one of the main environmental factors affecting the color change of the leaves of autumn-colored foliage trees. Therefore, measures such as artificial cooling can be used to induce the color change of these trees earlier in autumn, thereby extending the period of leaf color viewing and enhancing their ornamental value.

[0003] In the prior art, utility model patent with announcement number CN215957553U provides a cooling nozzle for garden engineering, including a base, a fixed column fixedly connected to the top of the base, a cavity opened inside the fixed column, an electric push rod fixedly connected to the bottom inner wall of the cavity, the output end of the electric push rod fixedly connected to the bottom end of the moving column, and a rotating block rotatably connected to the top end of the moving column.

[0004] The cooling sprinkler used in this landscaping project involves many components in its reciprocating mechanism. The lack of limiting mechanisms on the fixed and moving columns makes them prone to rotation, which may affect the operation of the reciprocating mechanism. The electric push rod is located inside the fixed column, affecting the lifting height of the equipment. Therefore, we propose a cooling sprinkler for autumn foliage trees to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling nozzle for autumn foliage trees to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling nozzle for autumn foliage trees includes a nozzle and a telescopic rod. The nozzle is fixedly mounted on top of a reciprocating mechanism, which drives the nozzle to oscillate repeatedly. The reciprocating mechanism includes a rotating rod at the bottom of the nozzle. A torsion spring is provided on the rotating rod to push it to rotate and return to its original position. A rack is provided on the rotating rod above the torsion spring. The rack intermittently meshes with a gear to transmit the oscillation of the rotating rod. The gear is connected to a motor for driving the gear to rotate. A mounting base for supporting the repeated oscillation of the rotating rod is rotatably connected to the bottom of the rotating rod. A telescopic rod for pushing the mounting base to rise and fall is fixedly connected to the bottom of the mounting base. A limiting mechanism is provided on the telescopic rod.

[0008] Preferably, the limiting mechanism is used to restrict the rotation of the mounting base on the telescopic rod.

[0009] Preferably, the limiting mechanism includes a limiting rod fixedly connected to the bottom of the mounting base, the bottom of which moves through the fixing block to limit the rotation of the mounting base.

[0010] Preferably, the top of the mounting base is provided with a groove, and the bottom of the rotating rod is rotatably inserted into the groove of the mounting base.

[0011] Preferably, the free end of the torsion spring is connected to the mounting base, and the rack is disposed on the side wall of the rotating rod.

[0012] Preferably, the rack is an arc-shaped rack.

[0013] Preferably, the gear is an incomplete gear, and the motor is mounted on a mounting base.

[0014] Preferably, the electric motor is a servo motor.

[0015] Preferably, the limiting rod is located on the outside of the telescopic rod, and the fixing block is located on the top side wall of the outer cylinder of the telescopic rod.

[0016] Preferably, the length of the limiting rod is less than or equal to the minimum length of the telescopic rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Start the motor. The motor drives the gear to rotate. The gear intermittently meshes with the rack. When the gear meshes with the rack, it drives the rotating rod to rotate on the mounting base. At the same time, the torsion spring is twisted and subjected to force. When the toothless area of ​​the gear turns to the rack, the gear and rack stop transmitting power. The torsion spring returns to its original state and pushes the rotating rod to rotate back to its original position. The rotating rod swings repeatedly, and the nozzle follows the swing of the rotating rod to spray water. This allows for stable driving of the nozzle to swing repeatedly, reducing the number of parts involved in the repetitive mechanism.

[0019] 2. Drive the telescopic rod to extend and retract, and the telescopic rod pushes the mounting base to rise and fall. Through the reciprocating mechanism, the nozzle follows the rise and fall. When the mounting base rises, it pulls the limit rod to slide on the fixed block. Through the limit rod and the fixed block, the rotation of the mounting base on the telescopic rod is restricted, so as to effectively support the mounting base and avoid affecting the lifting height of the equipment.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 A cooling nozzle for autumn foliage trees includes a nozzle 1 and a telescopic rod 4. The nozzle 1 is fixedly mounted on the top of a reciprocating mechanism 2, which drives the nozzle 1 to swing repeatedly. The reciprocating mechanism 2 includes a rotating rod 21 at the bottom of the nozzle 1. A torsion spring 22 is provided on the rotating rod 21 to push the rotating rod 21 to rotate and return to its original position. A rack 23 is provided on the rotating rod 21 above the torsion spring 22. The rack 23 intermittently meshes with a gear 24 to transmit the swing of the rotating rod 21. The gear 24 is connected to a motor 25 for driving the gear 24 to rotate. A mounting base 3 for supporting the repeated swing of the rotating rod 21 is rotatably connected to the bottom of the rotating rod 21. The top of the mounting base 3 is provided with a groove. The bottom of the rotating rod 21 is rotatably inserted into the groove of the mounting base 3. The free end of the torsion spring 22 is connected to the mounting base 3. The rack 23 can be an arc rack or a ring rack. The rack 23 is provided on the side wall of the rotating rod 21. The gear 24 is an incomplete gear. The motor 25 is a servo motor and is mounted on the mounting base 3.

[0026] The motor 25 is started, which drives the gear 24 to rotate. The gear 24 intermittently meshes with the rack 23. When the gear 24 meshes with the rack 23, it drives the rotating rod 21 to rotate on the mounting base 3. At the same time, the torsion spring 22 is twisted and subjected to force. When the toothless area of ​​the gear 24 turns to the rack 3, the gear 24 and the rack 3 stop transmitting power. The torsion spring 22 then returns to its original state, pushing the rotating rod 21 to rotate and return to its original position. The rotating rod 21 swings repeatedly, and the nozzle 1 follows the swing of the rotating rod 21 to spray water. This allows for stable driving of the nozzle 1 to swing repeatedly, reducing the number of parts involved in the repetitive mechanism 2.

[0027] The bottom of the mounting base 3 is fixedly connected to a telescopic rod 4 for pushing the mounting base 3 up and down. The bottom of the telescopic rod 4 is set on the ground or base. The telescopic rod 4 is equipped with a limiting mechanism 5, which is used to limit the rotation of the mounting base 3 on the telescopic rod 4. The limiting mechanism 5 includes a limiting rod 51 fixedly connected to the bottom of the mounting base 3. The bottom of the limiting rod 51 moves through a fixing block 52 to limit the rotation of the mounting base 3. The length of the limiting rod 51 is less than or equal to the minimum length of the telescopic rod 4. The limiting rod 51 is on the outside of the telescopic rod 4. The fixing block 52 is set on the top side wall of the outer cylinder of the telescopic rod 4. The telescopic rod 4 can be an electric or hydraulic telescopic rod, etc.

[0028] The telescopic rod 4 extends and retracts, and the telescopic rod 4 pushes the mounting base 3 to rise and fall. The nozzle 1 follows the repetitive mechanism 2 to rise and fall. When the mounting base 3 rises, it pulls the limit rod 51 to slide on the fixed block 52. Through the limit rod 51 and the fixed block 52, the mounting base 3 is restricted from rotating on the telescopic rod 4, so that the mounting base 3 can be effectively supported and the lifting height of the equipment can be avoided.

[0029] Working principle: The starting motor 25 drives the gear 24 to rotate. The gear 24 intermittently meshes with the rack 23. When the gear 24 meshes with the rack 23, it drives the rotating rod 21 to rotate on the mounting base 3. At the same time, the torsion spring 22 is twisted and subjected to force. When the toothless area of ​​the gear 24 turns to the rack 3, the gear 24 and rack 3 stop transmitting power, and the torsion spring 22 returns to its original state, pushing the rotating rod 21 to rotate back to its original position. The rotating rod 21 swings repeatedly, and the nozzle 1 follows the swing of the rotating rod 21 to spray water. This allows for stable driving of the nozzle 1 to swing repeatedly, reducing the number of parts involved in the repetitive mechanism 2. The telescopic rod 4 is driven to extend and retract, and the telescopic rod 4 pushes the mounting base 3 to rise and fall. Through the repetitive mechanism 2, the nozzle 1 follows the rise and fall. When the mounting base 3 rises, it pulls the limiting rod 51 to slide on the fixed block 52. Through the limiting rod 51 and the fixed block 52, the rotation of the mounting base 3 on the telescopic rod 4 is restricted, which can effectively support the mounting base 3 and avoid affecting the lifting height of the equipment.

[0030] The nozzle 1, the incomplete gear, and the telescopic rod 4 are all existing technologies and will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
