Description

Technical Field

[0001] The utility model relates to the technical field of tree maintenance, in particular to a tree spraying device for garden maintenance. Background Art

[0002] When maintaining garden trees, lime water is usually applied to the top of the tree roots. The main functions of applying lime water are: 1. Sterilization, prevention of bacterial infection, and accelerated wound healing; 2. Insecticide and insect prevention: it can prevent pests in the soil from crawling up the tree trunk to harm the tree; 3. Prevent frost damage and sunburn: because lime is white, it can reflect 40%-70% of the sunlight, so the temperature difference between the day and night is not much, so it is not easy to crack; 4. Delay the budding and flowering period of fruit trees to prevent early spring frost damage. Most of the work of applying lime water to maintain garden trees needs to be done manually, and the efficiency of applying lime water to trees manually is low.

[0003] The patent document with application number CN202322621767.3 and titled "A spraying device for protecting trees in forestry planting" discloses a device that can automatically apply lime water to trees. When in use, the device is pushed in front of the tree that needs to be sprayed with paint through the handle and the moving wheel, so that the tree is between two sets of symmetrical paint brushing parts, and the spraying is performed by adjusting the distance between the two sets of paint brushing parts. At this time, the user turns on the brushing distance adjustment motor, and the brushing distance adjustment motor drives the brushing distance adjustment screw to rotate on the support block. Under the guidance of the adjustment guide groove, the two sets of brushing distance adjustment parts move and approach along the direction of the brushing distance adjustment screw and the brushing position adjustment component, thereby driving the two sets of paint brushing parts to approach, and finally wrapping and contacting the tree. Then the user turns on the two sets of pumping motors. After the pumping motors are started, the paint in the paint box is pumped out from the paint pumping telescopic tube, and finally sprayed on the paint brushing parts through the paint spraying head. After the paint is sprayed, the paint brushing parts contact the trees and drain the paint to the trees. At this time, the user turns on the painting height adjustment rod. After the painting height adjustment rod is raised and lowered, it slides on the trees with the paint brushing parts, so as to paint the trees. However, in the process of applying lime water to the trees, the trunk parts of the trees close to the ground need to be coated with lime water. In this solution, due to the limitation of the coating height adjustment rod, the device cannot apply lime water to the trunk parts of the trees close to the ground, and manual additional coating is required later.

[0004] The patent document with application number CN201921512772.8 and titled "A Tree Spraying Device for Landscaping" discloses a tree spraying device that can increase the effective spraying area and effectively improve the spraying and maintenance efficiency of a single tree. When in use, the water supply mechanism is installed on the top of the mobile base to continuously supply water to the spraying assembly, and the spraying assembly is continuously sprayed and maintained on the trees through the lifting bracket mechanism. Since the lifting bracket mechanism is fixed on the mobile base, the spraying assembly cannot be lowered below the mobile base. Therefore, the trunk of the tree close to the ground cannot be effectively coated with lime water. At the same time, the ground outside some garden trees is paved with retaining stones. When applying lime water, after the mobile base contacts the retaining stones, it is easy for the spraying assembly to fail to embrace the trunk of the tree, so the tree cannot be effectively coated with lime water.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0044] Example 1: Reference Figure 1-Figure 3 As shown, the tree spraying device for garden maintenance includes a hollow fixed rod 1 and a hollow movable rod 2, the fixed rod 1 and the movable rod 2 are both arc-shaped, and the fixed rod 1 and the movable rod 2 form a ring.

[0045] A plurality of spray heads 8 are fixedly connected to the inner side of the fixed rod 1 and the inner side of the movable rod 2. A handle 3 is fixed to one end of the fixed rod 1, and a handle sleeve is sleeved on the end of the handle 3 away from the fixed rod 1.

[0046] The movable rod 2 is rotatably connected to the handle 3, and the movable rod 2 and the handle 3 are connected through a telescopic rod 7. Specifically, an opening 5 is provided on the handle 3, one end of the ear plate 4 is rotatably connected in the opening 5 through a pin 6, the other end of the ear plate 4 is fixedly connected to the movable rod 2, a connecting plate is fixed on the ear plate 4 and the handle 3, one end of the telescopic rod 7 is rotatably connected to the connecting plate on the ear plate 4, and the other end of the telescopic rod 7 is rotatably connected to the connecting plate on the handle 3.

[0047] A joint 9 is fixed on the fixed rod 1, and the joint 9 is communicated with the inside of the fixed rod 1. The joint 9 is communicated with a liquid pump through a hose, and the liquid pump is communicated with a storage tank, and lime water is stored in the storage tank.

[0048] A through hole is formed at one end of the fixed rod 1 away from the handle 3, and a connecting pipe 14 is fixedly connected to one end of the movable rod 2 away from the handle 3. The connecting pipe 14 is sealed and inserted in the through hole. Specifically, a sealing ring is fixed in the through hole, and the connecting pipe 14 is sealed and inserted in the through hole through the sealing ring. The connecting pipe 14 is arc-shaped and concentric with the pin 6.

[0049] Start the liquid pump to transport lime water into the fixed rod 1 and the movable rod 2 through the joint 9.

[0050] A flap 16 is elastically rotatably connected to the end of the fixed rod 1 away from the handle 3, and a sealing gasket 17 is fixed to the flap 16. After the connecting pipe 14 passes through the through hole, the flap 16 is driven to rotate. After the connecting pipe 14 exits the through hole, the flap 16 rotates and blocks the through hole through the sealing gasket 17. Specifically, the flap 16 is rotatably connected to the fixed rod 1 through a rotating shaft, and a torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixedly connected to the flap 16, and the other end of the torsion spring is fixedly connected to the fixed rod 1.

[0051] When it is necessary to spray lime water on the trunk of the tree, the telescopic rod 7 is started to shorten the telescopic rod 7, and the movable rod 2 and the ear plate 4 rotate around the pin 6. After the movable rod 2 rotates, the connecting pipe 14 is screwed out of the through hole. Then the trunk of the tree can enter between the fixed rod 1 and the movable rod 2. The movable rod 2 is restored. After the movable rod 2 is restored, the fixed rod 1 and the movable rod 2 form a ring and the trunk of the tree is located between the fixed rod 1 and the movable rod 2. At this time, the fixed rod 1 and the movable rod 2 are connected through the connecting pipe 14 and the one-way valve 15.

[0052] Start the liquid pump, hold the handle 3 and move the device from top to bottom, and the lime water will be sprayed from the nozzle 8 and attached to the tree trunk. Multiple nozzles 8 spray lime water at the same time, which can improve the spraying efficiency of lime water.

[0053] The fixed rod 1 and the movable rod 2 can be close to the ground, so that the tree trunk part close to the ground can be sprayed with lime water, and the tree trunk can be completely sprayed.

[0054] After spraying is completed, the telescopic rod 7 is started to rotate the movable rod 2. When the connecting pipe 14 is withdrawn from the through hole, the flap 16 rotates, and the through hole can be blocked by the sealing gasket 17. After the flap 16 blocks the through hole, the lime water in the fixed rod 1 can be prevented from flowing out through the through hole, thereby avoiding the waste of lime water.

[0055] The device is separated from the trunk of the tree. After that, the liquid pump can be started again, and the nozzle 8 on the fixing rod 1 is directed downward, so that the lime water sprayed from the nozzle 8 on the fixing rod 1 adheres to the root part of the tree above the ground. The fixing rod 1 can work alone, and the device has a wide range of applications.

[0056] Embodiment 2: Based on Embodiment 1, refer to Figure 1 , Figure 2 and Figure 4 As shown, multiple elastic support components are installed inside the fixed rod 1 and the movable rod 2. The elastic support component includes a fixed sleeve 10, which is fixed in the ring formed by the movable rod 2 and the fixed rod 1. The axial direction of the fixed sleeve 10 is parallel to the radial direction of the ring. An inner rod 11 is slidably arranged in the fixed sleeve 10, and the inner rod 11 is connected to the fixed sleeve 10 through a spring 13. A universal wheel 12 is installed on one end of the inner rod 11 outside the fixed sleeve 10.

[0057] When the fixed rod 1 and the movable rod 2 move up and down outside the trunk of the tree, the universal wheel 12 can roll and contact with the trunk of the tree. The inner rod 11 is elastically slidably connected in the fixed sleeve 10, so that the universal wheel 12 can pass over the protruding part (such as the pruned fork branch or the diseased protrusion) on the trunk of the tree.

[0058] When the fixed rod 1 and the movable rod 2 move up and down on the outside of the tree trunk, the elastic support assembly can stabilize the fixed rod 1 and the movable rod 2, and can assist in controlling the distance between the nozzle 8 and the tree trunk, thereby ensuring the spraying effect of the lime water.

[0059] Due to the universal wheel 12 installed on the inner rod 11, the device can rotate in the circumferential direction of the tree trunk, thereby causing the inner rod 11 to be misaligned with the protruding portion on the tree trunk, ensuring that the device can move up and down smoothly.

[0060] Embodiment 3: Based on Embodiment 1, refer to Figure 2 and Figure 3 As shown, a one-way valve 15 is installed at the end of the connecting pipe 14 in the movable rod 2, and the one-way valve 15 only allows lime water to enter the movable rod 2 through the connecting pipe 14.

[0061] After the movable rod 2 rotates, the flap 16 rotates to block the through hole. Since the one-way valve 15 only allows lime water to enter the movable rod 2 through the connecting pipe 14, the one-way valve 15 can prevent the lime water in the movable rod 2 from being discharged through the connecting pipe 14, thereby avoiding waste of lime water.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
