Description

Technical Field

[0001] The invention relates to the technical field of pest control, in particular to a device for applying lime water to branches and trunks for forestry pest control. Background Art

[0002] Lime water has certain bactericidal and insecticidal effects. It can kill some overwintering fungi, bacteria and pests parasitic on tree trunks, reduce the occurrence of diseases and insect pests, and pests generally do not like white and clean places. After applying lime water, pests in the soil dare not climb up the tree along the trunk. Therefore, in forestry, including some municipal projects such as street trees, there are operations of applying lime water to tree trunks. When applying lime water to tree trunks, it is generally done by manual brushing. Through the cooperation of multiple people, a large number of trees can be quickly painted. The conventional method is to manually use a brush to brush the lime water onto the tree. Nowadays, most people use manual backpack sprayers to carry lime water, and then use a nozzle to spray the tree trunk to improve the painting efficiency. However, when using a nozzle to spray lime water, in order to avoid polluting the surrounding environment, the spray range of the nozzle will not exceed the width of the tree trunk. When spraying, the staff needs to go around the tree trunk and spray the tree trunk in turn. The process is relatively complicated and cumbersome. When a large number of trees need to be sprayed, it is inconvenient for personnel to perform brushing operations. In addition, conventional nozzle spraying operations can easily cause excess lime water to flow along the tree trunk, resulting in a large amount of lime water near the bottom of the trunk and uneven distribution on the trunk.

The pedal and the slide cylinder can be reset by the elastic force of the elastic rope, so that the arc shell is reset. When the other pedal is stepped on, the pedal drives the slide cylinder upward through the traction rope, so that one end of a pull rope is close to the rectangular hole and one end of the other pull rope is away from the rectangular hole, so that the pull rope drives the arc shell to reverse more than half a circle, so that the arc shell can reciprocate around the tree trunk. The structure is simple and convenient for users to use; 4. When the arc shell reciprocates around the tree trunk, multiple moving plates on any smearing mechanism are all in contact with the tree trunk, and multiple moving plates are all in contact with the tree trunk along the curve of the tree trunk, so that the moving plates rely on their own card slots to pull the rubber card strips and soft strips along the tree trunk. When the arc shell reciprocates, the soft strip can rely on the bristles to smear the lime water ejected by the injection mechanism, so that the lime water is more evenly distributed on the tree trunk.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 8 In an embodiment of the present invention, a device for applying lime water to branches and trunks for preventing and controlling forest pests and diseases comprises: The base frame 100, the driving mechanism 200, the spraying mechanism 300 for reciprocatingly spraying lime water on the tree trunk, and the applying mechanism 400 for evenly applying the lime water on the tree trunk, the bottom ends of the bottom surface of the base frame 100 are fixedly connected with road wheels, the bottom end of the driving mechanism 200 is fixedly connected to the top surface of the base frame 100, the spraying mechanism 300 is fixedly connected to one side of the driving mechanism 200, the spraying mechanism 300 includes an arc plate 310, and one side of the arc plate 310 is fixedly connected to one side of the driving mechanism 200, and arc guide rails 330 are arranged at both ends of the top and bottom of the inner side wall of the arc plate 310, and Arc-shaped convex strips are provided at both ends of the top and bottom of the inner wall of the arc plate 310, and the two arc-shaped convex strips are respectively rotatably clamped in the adjacent arc-shaped guide rails 330, and an arc-shaped shell 320 is fixedly connected between the two arc-shaped guide rails 330, and a plurality of nozzles 321 are fixedly connected to the top of the inner wall of the arc-shaped shell 320, and the interiors of the plurality of nozzles 321 are connected to the interior of the arc-shaped shell 320, and a connecting tube 322 is fixedly connected to the bottom end of the outer wall of the arc-shaped shell 320, and the interior of the connecting tube 322 is connected to the interior of the arc-shaped shell 320, and two coating mechanisms 400 are respectively located at both ends of the inner arc surface of the arc-shaped shell 320.

[0020] Specifically, the base frame 100 is moved by the road wheels on the base frame 100. In the initial state, the arc shell 320 is located between the two arc convex strips on the inner wall of the arc plate 310, and the centers of the arc shell 320, the arc plate 310 and the two arc guide rails 330 are all on the same central axis. By pushing the base frame 100 close to the tree trunk, the trunk part enters between the two ends of the arc shell 320, so that the trunk is close to the center of the arc shell 320, and then by connecting the connecting pipe 322 to the container storing lime water, and using a hand pump or other water pump to inject lime water into the interior of the arc shell 320 through the connecting pipe 322, and the lime water is sprayed out from multiple nozzles 321.

At the same time, the arc shell 320 can block the water flow that splashes back from the tree. Hand pumps or other water pumps are all existing technologies and will not be repeated here.

[0021] Embodiment 1

[0022] like Figure 3-5 As shown, in this embodiment, both ends of the bottom surface of the arc plate 310 are fixedly connected with a sleeve frame 340, and a U-shaped plate 341 is arranged above the two sleeve frames 340, one side of the two U-shaped plates 341 is respectively fixedly connected to the two ends of the arc plate 310, and an L-shaped rod 342 is arranged below the two U-shaped plates 341, and the long arms of the two L-shaped rods 342 are respectively slidably sleeved in the two sleeve frames 340, and two bayonet holes 331 are provided on the inner bottom surface of the arc guide rail 330 located below, and one end of the short arms of the two L-shaped rods 342 are fixedly connected with a clamping block 343, and the two clamping blocks 343 are respectively movably clamped in the two bayonet holes 331, and a plurality of return springs 344 are fixedly connected between the top surfaces of the two L-shaped rods 342 and the inner bottom surfaces of the adjacent U-shaped plates 341.

[0023] In this embodiment, when the base frame 100 is moved, the arc shell 320 and the arc plate 310 are tilted and lifted with the two road wheels as fulcrums to move, so that the two L-shaped rods 342 are separated from the ground. At this time, the blocks 343 on the two L-shaped rods 342 can be automatically inserted into the adjacent slots 331 due to the adjacent return springs 344, so that the relative positions of the arc plate 310 and the arc shell 320 are fixed. When spraying the tree trunk, the tilted arc shell 320 and the arc plate 310 can be lowered to make the two L-shaped rods 342 contact the ground, so that the two L-shaped rods 342 slide up to make the two blocks 343 separate from the adjacent slots 331, so that the arc shell 320 can be rotated back and forth.

[0024] like Figure 1-Figure 3 and Figure 6 As shown, in this embodiment, the driving mechanism 200 includes: The frame 210, the guide rod 220, the slide 230 for controlling the pull rope 240 and the two pull ropes 240 for pulling the arc shell 320 to rotate, one side of the frame 210 is fixedly connected to one side of the arc plate 310, the top of the frame 210 is fixedly connected with a handle, the guide rod 220 is fixedly connected between the top and bottom ends of the frame 210, the inner wall of the slide 230 is slidably sleeved with the outer wall of the guide rod 220, one end of the two pull ropes 240 is fixedly connected to the two ends of the arc shell 320, a rectangular hole is provided in the center of the inner wall of the arc plate 310, and the other ends of the two pull ropes 240 pass through the rectangular hole, the other ends of the two pull ropes 240 are fixedly connected to the two ends of the slide 230, and the other side of the frame 210 is fixedly connected with a connecting plate 250, and one side of the connecting plate 250 is provided with two movable grooves 251, wherein one movable groove 251 is provided. The movable groove 251 is located below the other movable groove 251, and pedals 252 are slidably connected inside the two movable grooves 251, wherein one end of one pedal 252 is fixedly connected to the outer wall of the slide cylinder 230, and the top of the other side of the connecting plate 250 is rotatably connected to a roller 253, and the top of the slide cylinder 230 is fixedly connected to a traction rope 231, and one end of the traction rope 231 passes around the roller 253 and is fixedly connected to one end of the other pedal 252, and a plurality of elastic ropes 232 are fixedly connected between the top of the slide cylinder 230 and the inner top surface of the frame 210, two limiting rollers 311 are rotatably connected between the top and bottom sides of the inner wall of the rectangular hole, and the two pull ropes 240 respectively pass around the two limiting rollers 311, and the two opposite inner walls of the frame 210 are rotatably connected to guide rollers 211, and the two pull ropes 240 respectively pass around the two guide rollers 211.

[0025] During specific implementation, the two pull ropes 240 are easier to move through the limiting rollers 311 and the guide rollers 211. When moving the base frame 100, the user can hold the handle to drive the base frame 100 to move and tilt the curved plate 310. After the base frame 100 moves to a suitable place, the curved plate 310 can be straightened to make the two L-shaped rods 342 contact the ground, so that the block 343 is separated from the adjacent clamping hole 331. In the initial state, the slide 230 is suspended at the center of the frame 210 by the elastic rope 232, and then the user can step on the two pedals 252 in turn to make one pedal 252 drive the slide 230 to move downward first, so that the two ends of the slide 230 pull one end of the pull rope 240 away from the rectangular hole and the other end of the pull rope 240 close to the rectangular hole. Thereby, the arc shell 320 rotates more than half a circle, and then one pedal 252 is released, and then the slide 230 is pulled back to the center of the frame 210 by the elastic rope 232 due to its own recovery characteristics, and then another pedal 252 is stepped on, so that the other pedal 252 pulls the slide 230 upward through the traction rope 231, so that the two ends of the slide 230 pull a pull rope 240 with one end close to the rectangular hole and the other pull rope 240 away from the rectangular hole, so that the arc shell 320 is reversed more than half a circle, and then the pedal 252 is released, so that the slide 230 is suspended at the center of the frame 210 by the elastic rope 232 due to its own weight, so that the user can control the rotation angle of the arc shell 320 by stepping on the pedal 252, which is convenient for the user to use, and the structure is simple and easy to use.

[0026] like Figure 2 and Figure 7-8 As shown, in this embodiment, the smearing mechanism 400 includes: There are multiple movable plates 410, soft strips 420, sliders 430 and rails 440. The multiple movable plates 410 are arranged vertically in sequence. One side of the multiple movable plates 410 is provided with a slot 411, and the other side is fixedly connected with multiple rebound springs 412. One end of any rebound spring 412 is fixedly connected to the inner wall of the arc shell 320. The outer wall of the soft strip 420 is fixedly connected with a rubber clip 421, and the bottom end of the rubber clip 421 is fixedly sleeved inside the bottom slot 411. The rubber clip 421 is slidably connected to the inside of other slots 411 except the bottom slot 411. Bristles are fixedly adhered to the outer wall of the soft strip 420. The slider 430 is fixedly connected to the top of the soft strip 420. The bottom end of the rail 440 is fixedly connected to the top surface of the arc guide rail 330 located above, and one end of the slider 430 is slidably connected to the inside of the rail 440.

[0027] In a specific implementation, the soft strip 420 can be made of plastic or rubber, and its outer wall is attached with bristles. When the base frame 100 moves to make the trunk part enter between the two arms of the arc shell 320, the multiple movable plates 410 cause the soft strip 420 to collide with the trunk due to the adjacent rebound springs 412, and the multiple movable plates 410 are attached to the trunk along the curve of the trunk, so that the multiple movable plates 410 pull the soft strip 420 to always be attached to the trunk along the curve of the trunk, and then as the arc shell 320 rotates back and forth, the bristles on the soft strip 420 brush the trunk, and the lime water flowing along the trunk is brushed on the trunk, so that the lime water is more evenly applied to the trunk.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, a pressure spring 441 is provided to facilitate the resetting of the soft strip 420 .

[0030] like Figure 7 As shown, in this embodiment, a pressure spring 441 is fixedly connected between the inner bottom surface of the rail 440 and the slider 430 .

[0031] In a specific implementation, when multiple movable plates 410 are all attached to the tree trunk along the trunk curve due to adjacent rebound springs 412, the movable plates 410 can pull the soft strip 420 to be attached to the tree trunk along the trunk curve. When the movable plates 410 are separated from the trunk, the slider 430 at the top of the soft strip 420 can be driven to reset by the pressure spring 441, thereby facilitating the reset of the soft strip 420.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
