Description

Technical Field

[0001] This utility model relates to the field of forestry protection technology, specifically to a spraying device for protecting trees planted in forestry. Background Technology

[0002] In the process of planting trees, in order to ensure the healthy growth of trees, people often apply a protective layer to the bark in the face of unknown erosion in the natural environment. The coating forms a protective layer on the bark surface, which plays a certain role in protecting the trees, preventing sunburn, and preventing pests and diseases.

[0003] Currently, the nozzles on existing forestry tree planting and protection spraying devices can only spray one position. The entire device needs to be rotated to cover the surface around the tree with the sprayed liquid. This is time-consuming and laborious, and also results in inconsistent coverage of the sprayed liquid in different parts, making it difficult to guarantee the uniformity of spraying. Therefore, this utility model provides a forestry tree planting and protection spraying device. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-6 As shown, this embodiment proposes a spraying device for protecting trees in forestry planting, including a vehicle floor 1, with wheels 2 at the bottom of the vehicle floor 1, and a handle 3, a storage tank 4 and a support rod 5 fixedly installed on the top of the vehicle floor 1. A spraying component 100 is provided on one side of the support rod 5, and a lifting component 200 is provided on the support rod 5.

[0028] In detail, the storage tank 4 is equipped with a stirring mechanism. The storage tank 4 contains spraying liquid. The stirring mechanism includes a motor and a stirring rod. The stirring mechanism can uniformly stir the spraying liquid in the storage tank 4 to prevent the spraying liquid from settling and affecting the spraying effect.

[0029] The spraying assembly 100 includes a hydraulic pump 101, a crossbar 102, and clamping rods 103. The inlet of the hydraulic pump 101 is connected to the bottom of the storage tank 4, and the outlet of the hydraulic pump 101 is connected to a first spraying pipe 105. One end of the first spraying pipe 105 is connected to a telescopic hose 106, and one end of the telescopic hose 106 is connected to a second spraying pipe 107. One end of the second spraying pipe 107 is connected to a storage box 110. Clamping rods 103 are symmetrically arranged on one side of the crossbar 102. Limiting rings 104 are fixedly installed at one end of each clamping rod 103. The top of each limiting ring 104 has an arc-shaped groove 108, and arc-shaped teeth are fixedly installed on the sidewalls of each limiting ring 104. 109. A drive box 111 is fixedly installed at the bottom of the storage box 110. A drive motor 112 is fixedly installed inside the drive box 111. The output end of the drive motor 112 passes through the bearing to the bottom of the drive box 111 and a drive gear 113 is fixedly installed thereon. The drive gear 113 meshes with the arc-shaped gear 109. A locking block 114 is fixedly installed at the bottom of the drive box 111. The locking block 114 matches the arc-shaped slot 108 and is movably locked in the arc-shaped slot 108. A paint spray nozzle 115 is fixedly connected to one side of the storage box 110. A crossbar 102 is set on one side of the support vertical bar 5. A clamping mechanism 300 is set inside the crossbar 102.

[0030] In detail, the hydraulic pump 101 and the input end of the drive motor 112 are connected to the battery through an external cable. One end of the spraying pipe 105 is fixedly installed on one side of the support rod 5. The combined diameter of the two limit rings 104 is larger than the diameter of the tree, which makes it easy to clamp the tree in the two limit rings 104.

[0031] The clamping mechanism 300 includes a drive motor 301 fixedly installed on one side of the crossbar 102. The input end of the drive motor 301 is connected to a battery via an external cable. A bidirectional screw 303 is rotatably connected inside the crossbar 102. The output end of the drive motor 301 is fixedly installed on one end of the bidirectional screw 303. Sliding blocks 302 are threadedly connected to the outer surfaces of both ends of the bidirectional screw 303. One end of each sliding block 302 is fixedly installed on one end of a corresponding clamping rod 103. A through groove 304 is provided on one side of the crossbar 102 to facilitate the movement of the sliding blocks 302. The rear side of the crossbar 102 is in contact with the side wall of the supporting vertical rod 5. The sliding blocks 302 match the inner wall of the crossbar 102.

[0032] In detail, the clamping mechanism 300 can drive two limiting rings 104 to clamp the tree inside the limiting rings 104, so that the paint nozzle 115 can spray the tree evenly around the circumference along the merged limiting rings 104.

[0033] Preferably, the two limiting rings 104, the two arc-shaped grooves 108, and the two arc-shaped teeth 109 are arranged in a circular shape after closing.

[0034] Example 2

[0035] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a lifting assembly 200 including a second drive motor 201 fixedly installed on the top of the support vertical rod 5. The input end of the second drive motor 201 is connected to a battery through an external cable. A through groove 203 is opened on one side of the support vertical rod 5. A threaded rod 202 is rotatably connected in the through groove 203. The output end of the second drive motor 201 is fixedly installed on the top of the threaded rod 202. A sliding block 204 is threadedly connected to the outer surface of the threaded rod 202. One end of the sliding block 204 is fixedly installed on the rear side of the crossbar 102.

[0036] In detail, the spraying width and spraying height can be adjusted by the lifting component 200.

[0037] During operation, the operator first moves the device to the side of the tree requiring coating using wheels 2 and handles 3. Then, the drive motor 301 is started, driving the double-ended screw 303 to rotate. The double-ended screw 303 drives the two sliding blocks 302 to rotate relative to each other, thereby causing the limiting rings 104 at one end of the two crossbars 102 to move relative to each other, locking the tree in the two limiting rings 104 until the two limiting rings 104 are fully closed. Then, the drive motor 201 is started, driving the threaded rod 202 to rotate. The threaded rod 202 drives the sliding block 204 to move to the required height. Finally, the hydraulic pump 101 is started. The spray liquid, after being stirred in the storage tank 4, is drawn into the spray pipe 105, and then enters the storage box 110 through the telescopic hose 106 and the spray pipe 107. It is then sprayed out through the paint nozzle 115. At the same time, the drive motor 112 is started to drive the drive gear 113 to rotate. Because the drive gear 113 is meshed with the arc-shaped tooth 109, the storage box 110 on the top of the drive box 111 is driven to rotate circumferentially along the limiting ring 104. After the storage box 110 rotates clockwise once, it rotates counterclockwise once, which can effectively prevent the telescopic hose 106 from getting tangled with the tree.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
