A landscaping maintenance device

Abstract

This utility model discloses a landscaping maintenance device, relating to the field of landscaping. The device includes a base plate, a liquid storage tank mounted on top of the base plate, two support frames fixed to one side of the top of the base plate, and a hollow shaft mounted between the two support frames via bearings. A housing is fixed to one side of each support frame, and two baffles are mounted on the outer wall of the hollow shaft. This utility model, through the configuration of a bidirectional lead screw, a movable plate, a friction disc, a friction pad, and a housing, allows workers to precisely control the rotation of the hollow shaft using a braking structure composed of the bidirectional lead screw, movable plate, friction disc, and friction pad. This enables flexible adjustment of the spray pipe release length, preventing the spray pipe from tangling and knotting, thus improving work efficiency. Simultaneously, after the spray pipe is wound up, the friction disc and friction pad clamp the baffles, preventing the baffles from rotating arbitrarily and causing the wound spray pipe to loosen or slip off, thereby improving the stability of the hollow shaft after winding the spray pipe.

Description

Technical Field

[0001] This utility model relates to the field of landscaping and greening, specifically a landscaping maintenance device. Background Technology

[0002] Currently, the construction of gardens generally involves the transplanting and planting of flowers, trees and shrubs. In order to ensure the growth and survival of these plants, garden managers generally need to maintain the plants regularly. The most common methods are watering and spraying pesticides to maintain the vitality of the plants and prevent the occurrence of diseases and pests.

[0003] Existing landscaping maintenance spraying systems are equipped with spraying mechanisms for watering or spraying pesticides. These mechanisms typically consist of a pump, a mixing tank, and a winding mechanism (for the spray hose). During watering, the spray hose needs to be released from the winding mechanism and pulled to the appropriate length before spraying. After spraying, the hose needs to be wound up again to prevent it from being piled up haphazardly. However, during operation, if the worker has already pulled the hose to the required maintenance length, because the winding shaft has no brake, the hose will rotate clockwise under its own weight (such as the weight of the drooping section) or external forces (such as wind or slight pulling), causing the hollow shaft to rotate. This results in the hose continuously being released and lengthening, exceeding the intended maintenance range (for example, originally planned for shrubs within a 10-meter radius). When spraying pesticides, the spray nozzle may extend to 15 meters on its own, requiring workers to repeatedly adjust the nozzle, thus reducing work efficiency. Additionally, the reel is prone to spinning freely, causing the nozzle to loosen after winding due to shaft instability. This prevents it from tightly adhering to the reel and makes it prone to slipping off the shaft during subsequent uses. The loosened nozzle may accumulate on the outside of the baffle or above the base plate, potentially becoming entangled with other components (such as the pusher or casters). Furthermore, the loosened nozzle may snag on the caster axle, making it difficult to release the nozzle during subsequent uses and requiring time to untangle, severely impacting maintenance efficiency. Forced pulling may even damage the nozzle (such as tearing the pipe wall or detaching the joint), further reducing the stability of the rewound nozzle. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a garden greening maintenance device to solve the technical problem that the winding shaft is difficult to fix, which causes the winding shaft to rotate freely and thus affects its stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a garden greening maintenance device, comprising a base plate, a liquid storage tank installed on the top of the base plate, two support frames fixed on one side of the top of the base plate, and a hollow shaft installed between the two support frames via bearings, and a box fixed on one side of the support frames, two baffles installed on the outer wall of the hollow shaft, a bidirectional lead screw connected to the inside of the box via bearings, and two movable plates threaded to the outer wall of the bidirectional lead screw, with a friction disc fixed on the top of the movable plate, friction pads installed on the outer surface of one friction disc and the back of the other friction disc, and baffles installed on the outer surface and back of the movable plate.

[0006] By adopting the above technical solution, the friction disc is used in conjunction with the friction pad to clamp the baffle, thereby braking or fixing the rotation of the baffle and the hollow shaft, and controlling the release length of the spray pipe.

[0007] Furthermore, the outer wall of the hollow shaft is wound with a spray pipe, and the inlet end of the spray pipe is connected to the hollow shaft.

[0008] By adopting the above technical solution, the hollow shaft serves as both the winding carrier for the spray pipe and the liquid delivery channel. One end is connected to the delivery pipe via a rotary joint, and the other end is connected to the liquid inlet of the spray pipe, thus achieving stable delivery of liquid from the delivery pipe to the spray pipe.

[0009] Furthermore, a limiting rod is installed inside the housing, and the limiting rod passes through two movable plates.

[0010] By adopting the above technical solution, the limiting rod passes through the two movable plates, restricting the movable plates to only move in a straight line along the axis of the limiting rod, preventing the movable plates from rotating with the bidirectional lead screw, and ensuring that the two friction discs always move in parallel.

[0011] Furthermore, a top cover is installed on the top of the storage tank via a flange, and a motor is installed on the top of the top cover, with the output end of the motor connected to a stirring rack.

[0012] By adopting the above technical solution, the stirring rack rotates under the drive of the motor to stir the liquid in the storage tank, so that the liquid is fully mixed and the concentration of the sprayed liquid is uniform.

[0013] Furthermore, a liquid pump is installed on one side of the top of the base plate, and the inlet end of the liquid pump is connected to a liquid pumping pipe extending into the inside of the storage tank.

[0014] By adopting the above technical solution, the maintenance liquid in the storage tank is extracted by a pump to provide pressure for liquid delivery, ensuring that the liquid can smoothly pass through the delivery pipe and hollow shaft into the spray pipe.

[0015] Furthermore, the outlet end of the pump is connected to a delivery pipe, and a rotary joint is installed between the delivery pipe and the hollow shaft.

[0016] By adopting the above technical solution, the rotary joint is installed between the infusion tube and the hollow shaft, which can realize the relative rotation between the two, while ensuring sealing performance, preventing liquid leakage, and ensuring that the liquid can be continuously and stably delivered to the spray tube while the hollow shaft is rotating.

[0017] Furthermore, a battery is installed on the other side of the top of the base plate, and casters are installed around the bottom of the base plate.

[0018] By adopting the above technical solution, the battery provides power support for electrical components such as motors, liquid pumps, and controllers, ensuring that the device can operate normally without an external power source.

[0019] Furthermore, a pusher is fixed to the other side of the top of the base plate, and the outer wall of the pusher is fitted with two anti-slip sleeves made of rubber material.

[0020] By adopting the above technical solution, the pusher frame is designed to facilitate the movement of the pushing device within the garden green area. The anti-slip sleeve is made of rubber material, which increases the friction between the hand and the pusher frame, preventing the staff from slipping their hands during the pushing process. At the same time, the rubber material has a certain degree of elasticity, which improves the comfort of holding.

[0021] Furthermore, a controller is installed on the top of the pusher, and the battery is electrically connected to the controller, the motor and the liquid pump respectively.

[0022] By adopting the above technical solution, staff can control the start and stop of the motor and its speed (adjusting the stirring speed), and the start and stop of the liquid pump and its power (adjusting the spraying pressure) through the controller, thereby achieving precise control of the maintenance operation.

[0023] Furthermore, one end of the bidirectional lead screw extends to the outside of the housing and is equipped with a rotating handle, and a cover plate is bolted to one side of the housing.

[0024] By adopting the above technical solution, the operator can drive the bidirectional lead screw to rotate by rotating the handle, which facilitates quick adjustment of the position of the friction disc.

[0025] In summary, the present invention has the following main advantages: 1. This utility model, by setting up a bidirectional lead screw, a movable plate, a friction disc, a friction pad, and a housing, allows the operator to precisely control the rotation of the hollow shaft using the braking structure composed of the bidirectional lead screw, movable plate, friction disc, and friction pad. This enables flexible adjustment of the release length of the spray pipe, avoids tangling and knotting of the spray pipe, and improves work efficiency. At the same time, after the spray pipe is wound up, the friction disc and friction pad clamp the baffle plate to prevent the baffle plate from rotating arbitrarily, which could cause the wound spray pipe to loosen or slip off on its own, thereby improving the stability of the hollow shaft after winding the spray pipe. 2. This utility model sets a limiting rod that passes through two movable plates, restricting the movable plates to only move in a straight line along the axis of the limiting rod, preventing the movable plates from rotating with the bidirectional screw, and ensuring that the two friction discs always move in parallel. By setting a baffle, the baffle can block the through groove, preventing external impurities from entering the box through the through groove. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A type of garden greening maintenance device, such as Figures 1-6 As shown, the system includes a base plate 1, with a storage tank 2 mounted on top of the base plate 1. Two support frames 13 are fixed to one side of the top of the base plate 1, and a hollow shaft 15 is mounted between the two support frames 13 via bearings. A housing 17 is fixed to one side of the support frames 13. Two baffles 14 are mounted on the outer wall of the hollow shaft 15. A double-acting screw 19 is connected to the inside of the housing 17 via bearings, and two movable plates 21 are threadedly connected to the outer wall of the double-acting screw 19. A friction disc 22 is fixed to the top of the movable plate 21. Friction pads 23 are mounted on the outer surface of one friction disc 22 and the back of the other friction disc 22. The friction pads 23 are made of nitrile rubber. Both the outer surface and back of the housing 1 are equipped with baffles 25. The bottom of the baffles 25 fits against the top of the housing 17. The width of the baffles 25 is greater than the width of the through groove 24. The friction discs 22 are used in conjunction with the friction pads 23 to clamp the baffles 14, thereby braking or fixing the rotation of the baffles 14 and the hollow shaft 15, and controlling the release length of the spray pipe 26. The two friction discs 22 correspond to the two baffles 14 respectively. One end of the bidirectional screw 19 extends to the outside of the housing 17 and is equipped with a handle. A cover plate 18 is bolted to one side of the housing 17. The operator can drive the bidirectional screw 19 to rotate by rotating the handle, which facilitates quick adjustment of the position of the friction discs 22.

[0031] See Figures 1-5 The hollow shaft 15 has a spray pipe 26 wound around its outer wall, and the inlet end of the spray pipe 26 is connected to the hollow shaft 15. The hollow shaft 15 is both the winding carrier of the spray pipe 26 and the liquid delivery channel. One end is connected to the delivery pipe 12 through a rotary joint 16, and the other end is connected to the inlet end of the spray pipe 26, so as to realize the stable delivery of liquid from the delivery pipe 12 to the spray pipe 26. The outlet end of the spray pipe 26 is equipped with a nozzle. The top of the storage tank 2 is equipped with a top cover 3 through a flange. The top of the top cover 3 is equipped with a motor 4, and the output end of the motor 4 is connected to a stirring frame 5. The stirring frame 5 rotates under the drive of the motor 4 to stir the liquid in the storage tank 2, so that the liquid is fully mixed and the sprayed liquid has a uniform concentration. The top of the top cover 3 is connected to an inlet pipe 27, and the top end of the inlet pipe 27 is threaded with a sealing cap.

[0032] See Figures 1-4A liquid pump 11 is also installed on one side of the top of the base plate 1. The inlet end of the liquid pump 11 is connected to a liquid extraction pipe 10 extending into the inside of the storage tank 2. The liquid pump 11 extracts the maintenance liquid in the storage tank 2 to provide pressure for liquid delivery, ensuring that the liquid can smoothly pass through the delivery pipe 12 and the hollow shaft 15 into the spray pipe 26. The outlet end of the liquid pump 11 is connected to the delivery pipe 12, and a rotary joint 16 is installed between the delivery pipe 12 and the hollow shaft 15. The rotary joint 16 is installed between the delivery pipe 12 and the hollow shaft 15, which can realize the relative rotation between the two, while ensuring sealing performance to prevent liquid leakage and ensuring that the liquid can be continuously and stably delivered to the spray pipe 26 even when the hollow shaft 15 is rotating.

[0033] See Figures 1-4 A battery 7 is installed on the other side of the top of the base plate 1. Casters are installed around the bottom of the base plate 1. The battery 7 provides power to the electrical components such as the motor 4, the liquid pump 11, and the controller 8, ensuring that the device can work normally without an external power source. A push frame 6 is fixed on the other side of the top of the base plate 1. The push frame 6 facilitates the movement of the device in the garden green area. A controller 8 is installed on the top of the push frame 6. The battery 7 is electrically connected to the controller 8, the motor 4, and the liquid pump 11. The controller 8 is also electrically connected to the motor 4 and the liquid pump 11. The operator can control the start and stop of the motor 4 and its speed (adjusting the stirring speed) and the start and stop of the liquid pump 11 and its power (adjusting the spray pressure) through the controller 8 to achieve precise control of the maintenance operation.

[0034] Example 2: Based on the above embodiment 1, the following structure will be set to make it easier for staff to hold the pusher 6.

[0035] Specifically, the outer wall of the pusher 6 is fitted with two anti-slip sleeves 9 made of rubber. The anti-slip sleeves 9 are made of rubber to increase the friction between the hand and the pusher 6, preventing the operator's hand from slipping during the push. At the same time, the rubber material has a certain elasticity, which improves the comfort of holding.

[0036] Example 3: Based on the above embodiment 1, in order to improve the stability of the movable plate 21 when it moves, it is necessary to guide the movable plate 21, so the following structure will be set.

[0037] Specifically, a limiting rod 20 is installed inside the housing 17. The limiting rod 20 passes through the two movable plates 21 and restricts the movable plates 21 to move linearly along the axis of the limiting rod 20. This prevents the movable plates 21 from rotating with the bidirectional lead screw 19 and ensures that the two friction discs 22 always move in parallel.

[0038] The working principle of this utility model is as follows: First, the staff opens the sealing cap on the liquid inlet pipe 27, then pours clean water, pesticides, nutrient solution, etc. into the storage tank 2 in proportion, then closes the sealing cap, and then starts the motor 4 through the controller 8. The motor 4 drives the stirring rack 5 to rotate in the storage tank 2 to fully stir the liquid until the liquid is evenly mixed. After the stirring is completed, the motor 4 is turned off through the controller 8. Next, the worker holds the anti-slip sleeve 9 on the pusher 6 and pushes the device to move within the landscaping area via the universal wheels at the bottom. Depending on the location of the plants to be maintained, the device is moved to a suitable work location. Based on the required maintenance distance, the worker rotates the handle at the end of the bidirectional lead screw 19, driving it to rotate. Since the bidirectional lead screw 19 is threadedly connected to the movable plate 21, and the movable plate 21 can only move linearly under the guidance of the limit rod 20, the rotation of the bidirectional lead screw 19 causes the two movable plates 21 to move in opposite directions, separating the friction disc 22 from the baffle 14 and releasing the brakes on the baffle 14 and the hollow shaft 15. At this point, the worker can pull the free end of the spray pipe 26, causing the hollow shaft 15 to rotate and release the spray pipe 26, pulling it to the required length. After the length is determined, the handle is rotated in the opposite direction, causing the two movable plates 21 to move towards each other, driving the friction disc 22 and friction pad 23 to clamp the baffle 14. Friction force is used to fix the baffle 14, preventing the spray pipe 26 from releasing or retracting itself during use. The liquid pump 11 is started by the controller 8. The liquid pump 11 draws the well-mixed maintenance liquid from the storage tank 2 through the liquid pumping pipe 10 and delivers the liquid to the delivery pipe 12. The delivery pipe 12 is connected to the hollow shaft 15 through the rotary joint 16. After entering the hollow shaft 15, the liquid enters the spray pipe 26 through the connection end of the hollow shaft 15 and finally sprays out from the nozzle of the spray pipe 26 to perform maintenance operations such as watering, spraying pesticides, or fertilizing plants. During the spraying process, the power of the liquid pump 11 can be adjusted by the controller 8. Control the spray pressure and flow rate to adapt to the maintenance needs of different plants; after the maintenance work is completed, turn off the pump 11 through the controller 8; then rotate the handle to release the friction disc 22 from clamping the baffle 14, and wind the spray pipe back onto the hollow shaft 15 until the spray pipe 26 is completely retracted. Then rotate the handle in the opposite direction to make the friction disc 22 clamp the baffle 14, preventing the baffle 14 and the hollow shaft 15 from rotating at will, thus improving the stability of the hollow shaft 15 and the baffle 14. Finally, push the device to the designated storage location to complete the entire maintenance process.
