Description

Technical Field

[0001] The utility model relates to the technical field of forestry tree maintenance, in particular to a white-coating device for preventing and controlling plant diseases and insect pests in forestry. Background Art

[0002] Whitewashing refers to brushing a layer of white liquid on trees. The functions of whitewashing include (1) sterilizing, preventing infection by pathogens, and accelerating wound healing. (2) killing insects and preventing insects, killing overwintering eggs and stem-boring insects in the bark. Since pests generally prefer black and dirty places and do not like white and clean places, when trees are painted with snow-white lime water, pests in the soil will not dare to climb up the trees to make trouble, and the bark can also be prevented from being bitten by animals. (3) Preventing frost damage and sunburn, and avoiding early spring frost damage. In winter, the temperature is very low at night; during the day, the temperature rises due to the sun's exposure, and the trees are dark brown, which is easy to absorb heat, and the temperature of the trees also rises quickly. This alternation of cold and heat makes the trees easy to freeze and crack. Especially large trees, which are thick, dark in color, and have poor tissue toughness, are more likely to crack. After being painted with lime water, because the lime is white, it can reflect 40%-70% of the sunlight, so the temperature difference between the day and night is not much, so the trees are not easy to crack. Delay the budding and flowering period of fruit trees and prevent frost damage in early spring. (4) It is convenient for pedestrians at night. When the trees are painted white, they will reflect light. Pedestrians at night can see the road more clearly, and it also plays a beautifying role, giving people a very neat feeling.

[0003] At present, traditional manual whitewashing has the following disadvantages: (1) Manual whitewashing is labor-intensive, and whitewashing workers have to bend over for a long time, which puts a great load on the human lumbar spine and is harmful to the workers' health. (2) The liquid required for whitewashing is easy to corrode the operator's hand skin. (3) The steps of manual whitewashing are complicated, time-consuming, and inefficient. (4) The paint cannot be applied deep into the grooves by manual whitewashing, leaving space for bacteria and insect eggs to survive.

[0004] Patent document with application number 201120048109.4 discloses a new type of tree whitening machine, which uses a brush mechanism. The brush can only brush the surface of the tree. If the bark is damaged, the brush cannot enter the inside of the bark and cannot kill the insect eggs inside the bark. The liquid is not evenly applied, the pest control effect is poor, and the tree maintenance effect is not good. Utility Model Content

A liquid inlet pipe 24 is installed at the liquid inlet of the delivery pump 23, and the liquid inlet pipe 24 is connected to the inside of the medicine barrel 2; a liquid outlet pipe 25 is installed at the liquid outlet of the delivery pump 23, and the liquid outlet pipe 25 is a rubber hose.

[0040] A base plate 3 is mounted on the upper surface of the bottom plate 1 . A lifting mechanism 31 is disposed on the base plate 3 . The lifting mechanism 31 includes a slideway 311 vertically opened on the base plate 3 .

[0041] A vertically arranged lifting screw 312 is provided in the slide 311, and the lifting screw 312 is rotatably connected to the slide 311. The top of the lifting screw 312 extends to the top of the slide 311 and is connected to a lifting motor 313. The top of the lifting screw 312 is connected to the output shaft of the lifting motor 313 through a coupling. The top and bottom of the lifting screw 312 are respectively connected to a bearing seat 314 embedded in the base plate 3, and the lifting screw 312 is rotatably connected to the bearing seat 314.

[0042] A slider 315 is installed in the slideway 311 and is sleeved on the outside of the lifting screw 312 and threadedly connected to the lifting screw 312 .

[0043] A guide mechanism 32 is also provided on the base plate 3 . The guide mechanism 32 includes a guide groove 321 vertically provided on the base plate 3 . The slideway 311 and the guide groove 321 are provided in parallel.

[0044] A vertically arranged guide rod 322 is installed in the guide groove 321 , and the top and bottom of the guide rod 322 are respectively connected to a fixing seat 324 embedded in the base plate 3 . A guide sleeve 323 is installed in the guide groove 321 and is sleeved on the outside of the guide rod 322 and slidably connected to the guide rod 322 .

[0045] In order to further improve the stability of the lifting plate 41 during lifting, the number of the guide mechanisms 32 in this embodiment is two, and the two guide mechanisms 32 are symmetrically arranged on both sides of the lifting mechanism 31 .

[0046] The lifting mechanism 31 and the guiding mechanism 32 are connected to the horizontal driving mechanism 4 via a slider 315 and a guiding sleeve 323 respectively.

[0047] The horizontal driving mechanism 4 includes a horizontally arranged lifting plate 41 , one end of the slider 315 extends to the outside of the slideway 311 and is connected to the lifting plate 41 , and one end of the guide sleeve 323 extends to the outside of the guide groove 321 and is connected to the lifting plate 41 .

[0048] A slide groove 42 is provided on the lifting plate 41 , and a horizontally arranged bidirectional screw 43 is installed in the slide groove 42 . The bidirectional screw 43 is rotatably connected to the slide groove 42 , and one end of the bidirectional screw 43 passes through the lifting plate 41 and extends to the outside of the lifting plate 41 to connect to the driving motor 44 .

[0049] A support bearing seat 47 is installed at the middle position of the bidirectional screw 43 .

[0050] The driving motor 44 is a three-phase asynchronous AC motor with forward and reverse rotation functions.

[0051] The positive thread section and the negative thread section of the bidirectional screw 43 are respectively threadedly connected with threaded sleeves 45. Driven by the driving motor 44, the bidirectional screw 43 rotates, driving the two threaded sleeves 45 to move closer to or separate from each other.

[0052] The horizontal driving mechanism 4 is connected to the spraying mechanism 5 via a threaded sleeve 45 .

[0053] The spraying mechanism 5 includes two arc-shaped bearing plates 51 , and the threaded sleeve 45 is connected to the bearing plates 51 on the same side through a connecting rod 46 .

[0054] The two supporting plates 51 can form a hollow columnar structure, and the middle of the hollow columnar structure is a spraying space. The inner wall of the supporting plate 51 is equipped with nozzles 52 arranged in a rectangular array. A liquid distribution channel is opened in the supporting plate 51, and the nozzles 52 are connected to the liquid distribution channel.

[0055] A delivery port 53 communicating with the liquid distribution channel is formed on the outer wall of the carrier plate 51 . The delivery port 53 is connected to the liquid outlet pipe 25 on the delivery pump 23 .

[0056] The supporting plate 51 provides an installation basis for the arrangement of the liquid distributing channel and the nozzle 52 , supports the nozzle 52 , and also plays a blocking role to prevent the insect-proof paint sprayed from the nozzle 52 from splashing.

[0057] When spraying is required, the operator pours the insect-proof paint into the medicine barrel 2, and moves the device to the side of the tree that needs to be sprayed by the handrail 12.

[0058] like Figure 4 As shown, the initial state of the two supporting plates 51 is a separated state, and the edges of the two supporting plates 51 are not in contact. At this time, the two supporting plates 51 are located on both sides of the tree trunk, and the driving motor 44 is started. The driving motor 44 drives the bidirectional screw 43 to rotate forward, and the two threaded sleeves 45 approach each other. The two supporting plates 51 are driven by the corresponding threaded sleeves 45 to approach each other.

[0059] like Figure 2 As shown, two supporting plates 51 enclose a spraying space, and the trunk of the tree is located in the spraying space; then the delivery pump 23 is started, and the insect-proof paint is sprayed out from the nozzle 52 through the delivery pump 23, the liquid outlet pipe 25 and the liquid distribution channel to whiten the tree.

[0060] When the spraying height needs to be adjusted, the lifting motor 313 is started, and the lifting motor 313 drives the lifting screw 312 to rotate. At this time, the lifting plate 41 is lifted and lowered, and the spraying mechanism 5 is lifted and lowered accordingly to adjust the whitewashing position and evenly whitewash the trees.

[0061] like Figure 4As shown, when the spraying work is finished, the delivery pump 23 is turned off, the delivery of the insect-proof paint stops, the driving motor 44 drives the bidirectional screw 43 to rotate in the opposite direction, the two threaded sleeves 45 move away from each other, and the two supporting plates 51 move away from each other under the drive of the corresponding threaded sleeves 45. The two supporting plates 51 return to the initial positions on both sides of the tree, and the operator moves the device to another tree position that needs to be sprayed through the handrail 12, and repeats the above steps.

[0062] Example 2

[0063] like Figure 1 and Figure 3 As shown, a waterproof cloth 6 of the same size is connected below the bearing plate 51 , and the inner wall diameter of the columnar space surrounded by the two waterproof cloths 6 is not less than the inner wall diameter of the spraying space surrounded by the two bearing plates 51 .

[0064] A liquid collecting channel 61 is provided at the bottom of the inner wall of the waterproof cloth 6, and a recovery port 62 is opened at a position of the waterproof cloth 6 near the liquid collecting channel 61. The recovery port 62 penetrates the waterproof cloth 6 and is connected to a recovery pump 26 through a recovery pipe 27. The recovery pump 26 is connected to the medicine barrel 2, and the recovery pipe 27 is a rubber hose.

[0065] During the spraying operation, the insect-proof paint that is not sprayed onto the trunk of the tree falls back onto the relative supporting plate 51 or the inner wall of the waterproof cloth 6, and the insect-proof paint slides into the liquid collecting channel 61. The recovery pump 26 is started, and under the suction action of the recovery pump 26, the insect-proof paint in the liquid collecting channel 61 is recovered into the medicine barrel 2, thereby avoiding waste of liquid medicine and increasing the reuse rate.

[0066] A filter net 63 is provided at the port of the recovery port 62 located on the waterproof cloth 6 to prevent debris such as tree debris from entering the recovery port 62, prevent the recovery port 62 or the recovery pipe 27 from being blocked, and further avoid the problem of the recovery pump 26 being damaged due to empty pumping.

[0067] The waterproof cloth 6 is a flexible cloth. When the spraying mechanism 5 descends along with the lifting mechanism 31, the waterproof cloth 6 can be flexibly folded so that the bottom of the supporting plate 51 reaches a position close to the root of the tree trunk, ensuring that the lower nozzle 52 on the spraying mechanism 5 can spray the tree trunk near the root.

[0068] Example 3

[0069] like Figure 5-Figure 10 As shown, an auxiliary white spraying mechanism 7 is detachably installed above the spraying mechanism 5. The auxiliary white spraying mechanism 7 includes two arc-shaped receiving plates 71. A universal joint 72 is provided at the bottom of the receiving plate 71. The bottom of the universal joint 72 is detachably connected to the upper end surface of the bearing plate 51.

[0070] A support roller 73 and a plurality of nozzles 74 arranged in a rectangular array are provided on the inner side wall of the receiving plate 71. The support roller 73 is arranged on the receiving plate 71 through a support 731. The support roller 73 is rotatably connected to the support 731. A liquid channel is opened in the receiving plate 71. The liquid channel is connected to the liquid outlet pipe 25 through an auxiliary pipeline. A valve is provided on the auxiliary pipeline.

[0071] Elastic connecting parts 75 are respectively installed on the two side edges of each receiving plate 71 . The elastic connecting parts 75 are made of spandex fabric, and a waterproof layer is laid on the inner side wall of the elastic connecting parts 75 .

[0072] The elastic connection parts 75 of the two receiving plates 71 close to each other are detachably connected by means of buckles 76 or zippers.

[0073] The support 731 of the support roller 73 is provided with a support rod 732 on the end face close to the receiving plate 71. The support rod 732 is inserted into the receiving plate 71 and is slidably connected to the receiving plate 71. A retaining ring is provided at one end of the support rod 732 located in the receiving plate 71 to prevent the support rod 732 from being separated from the receiving plate 71 and to provide an axial guiding function for the support roller 73. A spring 733 is provided between the support 731 and the receiving plate 71 and is sleeved on the outside of the support rod 732 to adjust the distance between the support 731 and the receiving plate 71 to avoid squeezing the tree trunk and causing obstruction to the lifting and lowering movement.

[0074] The liquid channel can also be connected with a rubber branch tube, and the other end of the rubber branch tube is set near the support roller 73. A brush is set on the outside of the support roller 73. The insect-proof paint can reach the brush of the support roller 73 through the rubber branch tube. During the sliding of the support roller 73 and the branch 8, the brush whitewashes the outer wall of the branch 8.

[0075] like Figure 9-10 As shown, when it is necessary to spray the special-shaped tree trunk with branches 8, the receiving plate 71 is installed on the corresponding supporting plate 51. At this time, the two supporting plates 51 are located on both sides of the tree trunk, and the two receiving plates 71 correspond to the two branches 8 respectively. The two receiving plates 71 are located on both sides of the special-shaped tree trunk with branches 8. First, the two elastic connecting parts 75 close to each other are connected, and the position of the supporting roller 73 is adjusted so that the supporting roller 73 contacts the branch 8. Then, another group of two elastic connecting parts 75 close to each other are connected, and the valve on the auxiliary pipeline is opened. When the delivery pump 23 is started, the insect-proof paint will be delivered to the auxiliary pipeline, and then the special-shaped tree trunk will be whitewashed through the nozzle 74.

[0076] When the spraying mechanism 5 moves upward under the drive of the lifting mechanism 31, the auxiliary white-spraying mechanism 7 moves upward accordingly; as the outer contour of the tree branch 8 gradually becomes larger, the internal space of the auxiliary white-spraying mechanism 7 changes accordingly. Under the connecting action of the universal joint 72, the receiving plate 71 rotates outward relative to the supporting plate 51, and the internal space of the auxiliary white-spraying mechanism 7 becomes larger. Under the joint action of the supporting roller 73 and the elastic connecting part 75, the supporting roller 73 is always close to the outer contour of the tree branch 8, ensuring that the auxiliary white-spraying mechanism 7 can be lifted and lowered smoothly.

[0077] The auxiliary white-spraying mechanism 7 is used to white-paint the special-shaped tree trunks with branches 8, which effectively replaces the traditional manual method and solves the problem that the existing white-spraying device has a fixed white-painting space and cannot spray the special-shaped tree trunks at the branches 8.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
