Abstract

The application belongs to the technical field of landscaping, and particularly relates to a water-saving sprinkling machine for landscaping engineering, which comprises a cylinder, a cover plate fixedly connected to the top of the cylinder, a mounting frame fixedly installed on the cover plate, a motor fixedly installed on the mounting frame, a mixing mechanism arranged in the cylinder, a sprinkling mechanism arranged on the cover plate, a protection assembly and a pressurizing assembly arranged on the sprinkling mechanism.

Description

Technical Field

[0001] This invention relates to the field of landscaping technology, specifically to a water-saving sprinkler irrigation machine for landscaping projects. Background Technology

[0002] In landscaping projects (such as urban park greening, residential landscape maintenance, and municipal road greening management), sprinkler irrigation is a core element in ensuring the survival and growth of plants—lawns need regular watering to maintain root vitality, and trees need moist soil to promote nutrient absorption.

[0003] Currently, traditional sprinkler irrigation machines have the following problems when in use: After the traditional sprinkler irrigation machine finishes, the types of impurities in the green environment are complex and continuously generated. For example, in autumn, a large number of fallen leaves in parks break off and are carried into the sprinkler nozzle by the airflow. In the garden green environment, impurities such as fallen leaves, mud, sand, and weeds can easily enter the nozzle. These impurities will gradually adhere to the inner wall of the nozzle, initially causing the cross-sectional area of ​​the nozzle to shrink, resulting in problems such as "uneven water flow and shortened range". The nozzle and pipeline of traditional sprinkler irrigation machines are mostly integrated or threaded connection. When cleaning the blockage, it is necessary to carry tools such as wrenches and screwdrivers manually, which is time-consuming and labor-intensive. In view of this, a water-saving sprinkler irrigation machine for garden greening projects is proposed. Summary of the Invention

[0004] The main objective of this invention is to provide a water-saving sprinkler irrigation machine for landscaping projects, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a water-saving sprinkler irrigation machine for landscaping projects, comprising a cylinder, a cover plate fixedly connected to the top of the cylinder, a mounting frame fixedly installed on the cover plate, a motor fixedly installed on the mounting frame, a mixing mechanism disposed within the cylinder, a sprinkler irrigation mechanism disposed on the cover plate, and a protective component and a pressurizing component disposed on the sprinkler irrigation mechanism, the protective component comprising: A guide block, wherein a guide groove is provided on the outer wall of the guide block, and a round rod is slidably connected in the guide groove; A straight rod, wherein a round rod passes through and is fixedly connected to the round rod, a protective plate is fixedly connected to one end of the straight rod, and a counterweight is fixedly connected to the other end of the straight rod; and a collar, which is sleeved on the straight rod.

[0006] Preferably, the sprinkler mechanism includes a base, which is fixedly mounted on a cover plate. A sleeve rod is rotatably connected to the upper side of the base, and a support rod is slidably connected to the sleeve rod. A clamping bolt is threaded onto the outer wall of the sleeve rod. A U-shaped frame is fixedly connected to the top of the support rod, and a spray gun is rotatably connected to the inner surface of the U-shaped frame. When the spray gun is not in use, the straight rod rotates under the action of the counterweight, so that the protective plate can be tightly attached to the nozzle of the spray gun, thereby protecting the nozzle and preventing external impurities from entering the nozzle when the device is not in use. When the spray gun is in use, the spray gun sprays water, causing the protective plate to rotate downward. When it rotates upward again under the action of the counterweight, it can disperse the water sprayed by the spray gun. Furthermore, during the process of the water flow squeezing the protective plate, the protective plate drives the straight rod to move. The round rod slides in the guide groove, so that the protective plate can also move downward when it moves away from the spray gun, which facilitates the subsequent rotation of the straight rod by the water flow squeezing the protective plate.

[0007] Preferably, an adjustment assembly is provided on the outer wall of the U-shaped frame. The adjustment assembly includes a fixing block, which is fixedly connected to the outer wall of the U-shaped frame. The fixing block is threadedly connected to a screw, and a support ball is fixedly connected to the top of the screw. By rotating the screw, the support ball can be moved up and down, thereby adjusting the support angle of the spray gun.

[0008] Preferably, a horizontal plate is fixedly connected to the outer wall of the sleeve rod, and a straight groove is formed on the outer wall of the horizontal plate.

[0009] Preferably, a connecting rod is fixedly connected to the nozzle of the spray gun, and a pad is fixedly connected to the bottom end of the connecting rod. The outer shell of the spray gun and the collar are elastically connected by a tension spring. The use of the pad reduces the impact force when the straight rod contacts the pad during rotation, thereby reducing the impact between the protective plate and the nozzle of the spray gun. The use of the tension spring allows the collar to be pulled back to its original position when the spray gun is not in use, so that the round rod slides back to its original position in the guide groove, thereby ensuring that the protective plate can fit snugly against the nozzle of the spray gun.

[0010] Preferably, the pressurization assembly includes an air chamber, the outer wall of which has a one-way air inlet and a one-way exhaust pipe. The one-way exhaust pipe is connected to the spray gun. A piston rod is connected in the air chamber. The inner wall of the air chamber and the piston rod are elastically connected by a return spring. A crossbar is fixedly connected to the end of the piston rod. A hinge rod is rotatably connected to the end of the crossbar. A connector is hinged to the end of the hinge rod away from the crossbar. The connector is sleeved by a guide sleeve. The guide sleeve is fixedly connected to the outer shell of the spray gun.

[0011] Preferably, when the straight rod rotates and drives the counterweight to press the connecting piece upward, the hinge rod moves, driving the piston rod to compress the gas in the air chamber into the spray gun. In this way, the airflow can be compressed into the spray gun.

[0012] Preferably, the mixing mechanism includes a rotating shaft, which is fixed to the output shaft of a motor. A stirring rod is fixedly connected to the outer wall of the rotating shaft. A sealing sleeve is fitted around the outside of the rotating shaft and is fixedly connected to the bottom of a cover plate. A rotating assembly is provided on the rotating shaft. The output shaft of the motor drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate, thereby achieving the mixing of the powder and water.

[0013] Preferably, the rotating assembly includes a first transmission wheel, which is connected to a second transmission wheel via a transmission belt. The second transmission wheel is penetrated by a rotating rod and fixedly connected to the rotating rod. The rotating rod is rotatably connected to the cover plate. A disc is fixedly connected to the top of the rotating rod, and a small cylinder is fixedly connected to the top of the disc. The small cylinder is slidably connected in a straight groove. By rotating the shaft, the first transmission wheel rotates, which in turn drives the second transmission wheel to rotate, thus realizing the rotation of the rotating rod and the disc. This causes the small cylinder to rotate, and the small cylinder slides in the straight groove, causing the horizontal plate to swing back and forth, which in turn drives the sleeve rod to rotate back and forth with a small amplitude, thereby increasing the spraying range of the spray gun.

[0014] Preferably, the outer wall of the cylinder is provided with a water inlet and a water outlet, the water outlet is connected to the spray gun through a hose, and the top of the cover plate is provided with a feed inlet.

[0015] This invention provides a water-saving sprinkler irrigation machine for landscaping projects. It has the following beneficial effects: (1) When the water-saving sprinkler used in this landscaping project is idle, the counterweight of the protective component drives the straight rod to rotate by gravity, so that the protective plate is in close contact with the nozzle of the spray gun. This can block impurities such as fallen leaves and mud from entering the nozzle, avoiding the problem of uneven water flow and shortened range caused by impurities adhering to the nozzle. When spraying, the water flow squeezes the protective plate to rotate the straight rod, and the round rod slides along the guide groove of the guide block to ensure that the protective plate smoothly avoids the water flow. Moreover, when the counterweight drives the protective plate to reset, it can also disperse the water flow and improve the uniformity of spraying. There is no need for frequent manual disassembly and cleaning of the nozzle, reducing the use of tools such as wrenches and screwdrivers, and reducing maintenance time and labor costs.

[0016] (2) The water-saving sprinkler used in this landscaping project uses a pressurizing component. During the sprinkler process, the straight rod rotates and drives the counterweight to squeeze the connecting parts of the pressurizing component, causing the connecting parts to rise along the guide sleeve. This pushes the hinge rod to move the cross rod and piston rod. The piston rod squeezes the gas in the air chamber. The gas enters the spray gun through the one-way exhaust pipe and mixes with the water to form a gas-water mixture, which increases the water jet pressure and range. At the same time, the air chamber is automatically replenished with air through the one-way air inlet. The reset spring assists the piston rod to reset, achieving continuous pressurization. The pressurized water has a wider coverage area and stronger penetration, which can reduce the number of repeated sprinkler irrigations and achieve water-saving effect.

[0017] (3) The water-saving sprinkler irrigation machine used in this landscaping project can be adjusted in multiple dimensions to adapt to different scenarios. Loosening the clamping bolts on the sleeve rod allows the support rod to slide up and down to adjust the height of the spray gun. Rotating the screw on the U-shaped frame allows the bottom of the spray gun to be lifted by the support ball, changing the spray angle of the spray gun. In addition, when the motor drives the rotating shaft of the mixing mechanism to rotate, the first transmission wheel drives the second transmission wheel and the rotating rod to rotate through the transmission belt. The disc and the small cylinder at the top of the rotating rod rotate synchronously. The small cylinder slides in the straight groove of the horizontal plate, driving the sleeve rod to drive the spray gun to swing back and forth in small amplitudes. The combination of multi-angle adjustment and automatic swing greatly reduces the spray dead angle and improves the coverage efficiency of the green area. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9 This invention proposes a water-saving sprinkler irrigation machine for landscaping projects, including a cylinder 1. The outer wall of the cylinder 1 is provided with an inlet 101 and an outlet 102. A cover plate 2 is fixedly connected to the top of the cylinder 1. A feed inlet 21 is provided on the top of the cover plate 2. The feed inlet 21 is used to add pesticide powder. When it is not necessary to add pesticide powder, the feed inlet 21 can be closed. A mounting frame 3 is fixedly installed on the cover plate 2. A motor 4 is fixedly installed on the mounting frame 3. A mixing mechanism 5 is provided in the cylinder 1. A sprinkler irrigation mechanism 6 is provided on the cover plate 2. A protective component 7 and a pressurizing component 8 are provided on the sprinkler irrigation mechanism 6.

[0024] In an embodiment of the present invention, the sprinkler mechanism 6 includes a base 61, which is fixedly mounted on a cover plate 2. A sleeve rod 62 is rotatably connected to the upper side of the base 61, and a support rod 63 is slidably connected in the sleeve rod 62. A clamping bolt 64 is threadedly connected to the outer wall of the sleeve rod 62. A U-shaped frame 65 is fixedly connected to the top of the support rod 63, and a spray gun 66 is rotatably connected to the inner surface of the U-shaped frame 65. The water outlet 102 is connected to the spray gun 66 through a hose 103. A pump body is provided at the water outlet 102. By rotating the clamping bolt 64, the clamping bolt 64 is moved away from the support rod 63, thereby releasing the limiting fixation of the support rod 63. After adjusting the height of the U-shaped frame 65 by pulling the support rod 63, the clamping bolt 64 is tightened. The operation is convenient. At the same time, the pump body can deliver the water flow from the water outlet 102 to the spray gun 66, so that the water flow is sprayed out to irrigate the garden plants.

[0025] Furthermore, an adjustment component 67 is provided on the outer wall of the U-shaped frame 65. The adjustment component 67 includes a fixing block 671, which is fixedly connected to the outer wall of the U-shaped frame 65. The fixing block 671 is threadedly connected to a screw 672, and a support ball 673 is fixedly connected to the top of the screw 672. By rotating the screw 672, the support ball 673 can be driven to rise and fall, thereby adjusting the support angle of the spray gun 66 and changing the spraying range of the spray gun 66.

[0026] In an embodiment of the present invention, the protective component 7 includes a guide block 71, a straight rod 74, and a collar 77. A guide groove 72 is formed on the outer wall of the guide block 71, and a round rod 73 is slidably connected in the guide groove 72. The straight rod 74 is penetrated by the round rod 73 and fixedly connected to it. A protective plate 75 is fixedly connected to one end of the straight rod 74, and a counterweight 76 is fixedly connected to the other end. The collar 77 is sleeved on the straight rod 74. The outer shell of the spray gun 66 is elastically connected to the collar 77 via a tension spring. When the spray gun 66 is in use, it sprays water, allowing the protective plate 75 to move and rotate. When the protective plate 75 rotates upward again under the action of the counterweight 76, it disperses the water sprayed by the spray gun 66, improving the uniformity of spraying. Furthermore, during the process of the water flow squeezing the protective plate 75, the protective plate 75 drives the straight rod 74... The rod 74 moves, and the round rod 73 slides in the guide groove 72, allowing the protective plate 75 to move downwards while moving away from the spray gun 66. This facilitates the subsequent rotation of the straight rod 74 by the pressure of the water flow on the protective plate 75. When the spray gun 66 is not in use, the tension spring can pull the collar 77 to return to its original position, allowing the round rod 73 to slide back to its original position in the guide groove 72. At the same time, under the action of the counterweight 76, the straight rod 74 rotates, allowing the protective plate 75 to fit tightly against the nozzle of the spray gun 66, thus protecting the nozzle and preventing impurities such as fallen leaves and mud from entering the nozzle. This avoids the problem of uneven water flow and shortened range caused by impurities adhering to the nozzle. It also eliminates the need for frequent manual disassembly and cleaning of the nozzle, reducing the use of tools such as wrenches and screwdrivers, and lowering maintenance time and labor costs.

[0027] Furthermore, a connecting rod 661 is fixedly connected to the lower part of the nozzle of the spray gun 66, and a pad 662 is fixedly connected to the bottom end of the connecting rod 661. When the straight rod 74 contacts the pad 662, the impact force is reduced, thereby reducing the impact between the protective plate 75 and the nozzle of the spray gun 66.

[0028] In an embodiment of the present invention, the pressurizing assembly 8 includes an air chamber 81. A one-way air inlet 82 and a one-way exhaust pipe 83 are provided on the outer wall of the air chamber 81. The one-way exhaust pipe 83 is connected to the spray gun 66. A piston rod 84 is connected within the air chamber 81. The inner wall of the air chamber 81 and the piston rod 84 are elastically connected by a return spring. A crossbar 85 is fixedly connected to the end of the piston rod 84. A hinge rod 86 is rotatably connected to the end of the crossbar 85. A connector 87 is hinged to the end of the hinge rod 86 away from the crossbar 85. The connector 87 is sleeved by a guide sleeve 88, which is fixedly connected to the spray gun 66. On the outer casing, during the irrigation process, the straight rod 74 rotates, causing the counterweight 76 to press the connecting piece 87 upward. The hinge rod 86 moves, causing the piston rod 84 to compress the gas in the air chamber 81 into the spray gun 66. The gas enters the spray gun 66 through the one-way exhaust pipe 83, mixes with the water flow to form an air-water mixture, and increases the water flow spray pressure and range. At the same time, after the return spring assists the piston rod 84 to return to its original position, the air chamber 81 automatically replenishes air through the one-way air inlet 82 to achieve continuous pressurization. The pressurized water flow has a wider coverage area and stronger penetration, which can reduce the number of repeated irrigations and achieve water-saving effect.

[0029] In an embodiment of the present invention, the mixing mechanism 5 includes a rotating shaft 51, which is fixed to the output shaft of the motor 4. A stirring rod 52 is fixedly connected to the outer wall of the rotating shaft 51. A sealing sleeve 53 is fitted around the outside of the rotating shaft 51 and is fixedly connected to the cover plate 2. A rotating assembly 54 is provided on the rotating shaft 51. The rotating assembly 54 includes a first transmission wheel 541, which is connected to a second transmission wheel 543 via a transmission belt 542. The second transmission wheel 543 is penetrated by a rotating rod 544 and is fixedly connected to the rotating rod 544. The rotating rod 544 is rotatably connected to the cover plate 2. A disc 545 is fixedly connected to the top of the rotating rod 544, and a small cylinder 546 is fixedly connected to the top of the disc 545. The outer wall of the sleeve rod 62 is... A horizontal plate 68 is fixedly connected, and a straight groove 69 is opened on the outer wall of the horizontal plate 68. A small cylinder 546 is slidably connected in the straight groove 69. The output shaft of the motor 4 rotates, which drives the rotating shaft 51 to rotate, and then drives the stirring rod 52 to rotate, which facilitates the mixing of powder and water. At the same time, during the rotation of the rotating shaft 51, the first transmission wheel 541 drives the second transmission wheel 543 and the rotating rod 544 to rotate through the transmission belt 542. The disc 545 at the top of the rotating rod 544 rotates synchronously with the small cylinder 546. The small cylinder 546 slides in the straight groove 69 of the horizontal plate 68, and the drive sleeve 62 drives the spray gun 66 to swing back and forth in small amplitude. The combination of multi-angle adjustment and automatic swing greatly reduces the spray dead angle and improves the coverage efficiency of green areas.

[0030] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0031] In use, first, rotate the clamping bolt 64 to move it away from the support rod 63, thus releasing the limiting fixation of the support rod 63. Then, pull the support rod 63 to adjust the height of the U-shaped frame 65, and tighten the clamping bolt 64. Then, rotate the screw 672 to drive the support ball 673 to rise and fall, thereby adjusting the support angle of the spray gun 66. Then, start the pump body, which can deliver the water flow from the outlet 102 to the spray gun 66, so that the water flow can spray out to irrigate the garden plants. During this process, the spray gun 66 sprays water, which allows the protective plate 75 to move and rotate. As the water flow squeezes the protective plate 75, the protective plate 75 drives the straight rod 74 to move, and the round rod 73 slides in the guide groove 72, so that the protective plate 75 can also move downward when it moves away from the spray gun 66. When the protective plate 75 rotates upward again under the action of the counterweight 76, it can disperse the water flow sprayed by the spray gun 66 and improve the uniformity of spraying. Meanwhile, during the sprinkler irrigation process, the straight rod 74 rotates, causing the counterweight 76 to press the connecting piece 87 upward. The hinge rod 86 moves, causing the piston rod 84 to press the gas in the air chamber 81 into the spray gun 66. The gas enters the spray gun 66 through the one-way exhaust pipe 83 and mixes with the water to form an air-water mixture, which increases the water jet pressure and range. After the return spring assists the piston rod 84 to return to its original position, the air chamber 81 automatically replenishes air through the one-way air inlet 82 to achieve continuous pressurization. The pressurized water flow covers a wider range. At the same time, the motor 4 is started, and the output shaft of the motor 4 rotates, which drives the rotating shaft 51 to rotate, and then drives the stirring rod 52 to rotate, which facilitates the mixing of powder and water. Meanwhile, during the rotation of the rotating shaft 51, the first transmission wheel 541 drives the second transmission wheel 543 and the rotating rod 544 to rotate through the transmission belt 542. The disc 545 at the top of the rotating rod 544 and the small cylinder 546 rotate synchronously. The small cylinder 546 slides in the straight groove 69 of the horizontal plate 68, and the drive sleeve 62 drives the spray gun 66 to swing back and forth in a small amplitude, reducing spray dead angles and improving the coverage of green areas. Meanwhile, when the spray gun 66 is not in use, the tension spring can pull the collar 77 to reset, allowing the round rod 73 to slide back in the guide groove 72. At the same time, under the action of the counterweight 76, the straight rod 74 rotates, so that the protective plate 75 can be tightly attached to the nozzle of the spray gun 66, thus protecting the nozzle and preventing impurities such as fallen leaves and mud from entering the nozzle.
