[0001] The invention relates to the technical field of fumigation devices, and more specifically to a fumigation device for preventing and controlling plant diseases and insect pests in forestry. Background Art

[0002] Forestry trees are greatly harmed by pests and diseases during planting. Fumigation is usually used to prevent and control forestry pests and diseases. The toxic gases evaporated by fumigation agents reach a certain concentration in the air, enter the internal tissues through the respiratory system of pests, and cause poisoning, thus achieving the effect of preventing and controlling forestry pests and diseases.

[0003] The shortcomings of the existing technology: When preventing and controlling forest pests and diseases, the fumigation mist is diffused around the trees to kill the pests on the trees. However, most of the existing forest fumigation equipment finds it difficult to cover the trees with the mist when the trees are at a high height, and the mist diffusion is easily disturbed by the external wind, which makes the mist diffusion uneven, resulting in poor fumigation and pest control effect. For this reason, we propose a fumigation device for forest pest control. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical scheme of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The forestry pest control fumigation device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0031] like Figure 1-8 As shown, in one embodiment, a forestry pest control fumigation device is proposed, including a mounting platform 1, a support frame 101 is mounted on the upper end of the mounting platform 1, a fumigation generator 102 is arranged on the upper end of the support frame 101, a telescopic assembly 2 is mounted on the upper end of the mounting platform 1, a fumigation assembly 3 is arranged in the telescopic assembly 2, the fumigation assembly 3 includes a spray mechanism 31, a swing mechanism 32 and an isolation mechanism 33, the spray mechanism 31 includes a connecting arm 311, a connecting frame 312, an arc disk 313 and an aerosol nozzle 315, a pair of connecting arms 311 are rotatably connected in the telescopic assembly 2, the connecting frame 312 is mounted on the connecting arm 311, the arc disk 313 is mounted on the connecting frame 312, a plurality of movable grooves 314 are opened on the upper end surface of the arc disk 313, and the aerosol nozzle 315 is rotatably connected in the movable groove 314 through a rotating shaft;

[0032] The swing mechanism 32 includes a first gear 321, a rack 322, a connecting rod 324 and an electric push rod 323. The first gear 321 is installed on the rotating shaft. The rack 322 is slidably connected in the arc disk 313 and meshes with the first gear 321. The electric push rod 323 is installed on the arc disk 313. The output end of the electric push rod 323 is fixedly connected with the connecting rod 324. The lower ends of multiple racks 322 are fixedly connected to the connecting rod 324. The connecting rod 324 is slidably connected to the arc disk 313 through a guide rod 325. The isolation mechanism 33 is used to isolate external airflow.

[0033] In actual application, the embodiment of the present invention is controlled to rotate and unfold the connecting arm 311 so that the arc disk 313 is unfolded. At this time, there will be a large gap between the arc disks 313. Then, the telescopic component 2 is controlled to operate, and the connecting arm 311 and the arc disk 313 are controlled to move. At this time, the arc disk 313 will pass over the trees. Then, the connecting arm 311 is controlled to rotate again to drive the arc disk 313 to merge. At this time, the trees will be located at the center of the merged arc disk 313. Then, the vaporized medicine is sprayed out through the aerosol nozzle 315, and the vaporized medicine is used to fumigate the trees above. At the same time, when the aerosol nozzle 315 sprays the vaporized medicine, the electric push rod 323 is controlled to operate, and the electric push rod 323 is controlled to operate. The push rod 323 will drive the connecting rod 324 to move back and forth up and down, and then drive the multiple racks 322 to move back and forth up and down in the arc disk 313. The racks 322 will drive the first gear 321 to rotate through the meshing of the teeth, and then drive the multiple aerosol nozzles 315 to swing back and forth at the same time through the rotating shaft, so that the trajectory of the vaporized medicine sprayed by the aerosol nozzle 315 swings in an S-shaped curve, thereby increasing the area covered by the vaporized medicine on the trees. At the same time, when the vaporized medicine is sprayed, the isolation mechanism 33 is used to reduce the interference of the external airflow on the flow direction of the vaporized medicine, so that the vaporized medicine diffuses more evenly on the trees, which can have a better fumigation and insecticide effect on the trees.

[0034] like Figure 2 and 5 As shown, as a preferred embodiment of the present invention, a first three-way pipe 316 is installed at the output end of the fumigation generator 102, and the other two ends of the first three-way pipe 316 away from the fumigation generator 102 are installed with first corrugated hoses 317, and one end of the first corrugated hose 317 away from the first three-way pipe 316 is connected to a first connecting pipe 318, and multiple aerosol nozzles 315 are connected to the first connecting pipe 318 through the connecting hose, and the first connecting pipe 318 is fixedly connected to the arc disk 313 through the reinforcement frame.

[0035] In actual application, the embodiment of the present invention is to add medicine into the fumigation generator 102, and then operate the fumigation generator 102 to vaporize the medicine. The vaporized medicine is then transported through the first three-way pipe 316, the first corrugated hose 317, the first connecting pipe 318 and the connecting hose, and finally the vaporized medicine is sprayed out through the aerosol nozzle 315.

[0036] In one case of the embodiment of the present invention, since the aerosol spray head 315 and the connecting pipe are connected via a connecting hose, a certain activity space is provided for the aerosol spray head 315 to rotate, thereby avoiding motion interference.

[0037] like Figure 5 and 9 As shown, as another preferred embodiment of the present invention, the isolation mechanism 33 includes a plurality of air curtain nozzles 331 installed in the arc disk 313, the air curtain nozzles 331 are located outside the aerosol nozzles 315, and the air curtain nozzles 331 are inclined to the surroundings.

[0038] In actual application, when the atomizing mechanism is in operation, the gas is sprayed out through the air curtain nozzle 331, and a conical air curtain can be formed around the vaporized medicine to isolate the external airflow, thereby preventing the external airflow from interfering with the diffusion mode of the vaporized medicine, so that the vaporized medicine can evenly cover the trees, thereby achieving a good fumigation and insecticide effect. Fig.10 As shown, the dotted line is the trajectory of the air curtain airflow, and the arc line is the diffusion trajectory of the vaporized drug.

[0039] In one case of an embodiment of the present invention, since the air curtain nozzle 331 is inclined outward and does not come into direct contact with the vaporized medicine, it can guide the diffusion direction of the vaporized medicine while isolating it from external airflow interference. When the aerosol nozzle 315 swings, the vaporized medicine diffuses upward, thereby achieving the effect of allowing the vaporized medicine to spread from bottom to top to cover the trees for fumigation and insecticide.

[0040] like Figure 2 and 5 As shown, as another preferred embodiment of the present invention, an air pump 332 is installed on the upper end of the support frame 101, a second three-way pipe 333 is installed on the output end of the air pump 332, second corrugated hoses 334 are installed on the other two ends of the second three-way pipe 333 away from the air pump 332, one end of the second corrugated hose 334 away from the second three-way pipe 333 is connected to a second connecting pipe 335, and multiple air curtain nozzles 331 are connected to the second connecting pipe 335.

[0041] In actual application, by controlling the operation of the air pump 332, the air pump 332 will deliver gas through the second three-way pipe 333, the second corrugated hose 334 and the second connecting pipe 335, and then spray gas through the air curtain nozzle 331 to form an air curtain that isolates the external airflow.

[0042] like Figure 1 and 4 As shown, as another preferred embodiment of the present invention, the telescopic assembly 2 includes a multi-stage electric telescopic rod 201, a slide 202 and a mounting block 203. The multi-stage electric telescopic rod 201 and a pair of slides 202 are both mounted on the mounting platform 1. The mounting block 203 is slidably connected to the circumferential surface of the slide 202, and the output end of the multi-stage electric telescopic rod 201 is fixedly connected to the mounting block 203.

[0043] In actual application, the embodiment of the present invention can drive the mounting block 203 to slide on the slide seat 202 by controlling the operation of the multi-stage electric telescopic rod 201, thereby controlling the fumigation assembly 3 to be pushed out, and the trees can be surrounded by the arc-shaped plate 313 for subsequent fumigation operations. When not in use, the fumigation assembly 3 can be pulled back and stored to avoid collision damage to the fumigation assembly 3. At the same time, the equipment space can be reduced, making it easier to move the equipment.

[0044] like Figure 1 and 4 As shown, as another preferred embodiment of the present invention, an expansion mechanism 4 is installed in the mounting block 203, and the expansion mechanism 4 is connected to the fumigation assembly 3. The expansion mechanism 4 includes a drive shaft 402, a drive motor 401 and a second gear 403. The drive motor 401 is installed on the mounting block 203, and the drive shaft 402 is rotatably connected in the mounting block 203. The connecting arm 311 is fixedly connected to the drive shaft 402 and is slidably connected to the mounting block 203. The output end of the drive motor 401 is fixedly connected to one of the drive shafts 402, and the second gears 403 are installed on the circumferential surface of the drive shaft 402, and the second gears 403 are meshed with each other.

[0045] In actual application, the embodiment of the present invention is controlled to operate the driving motor 401, and the driving motor 401 will drive the driving shaft 402 to rotate. At this time, under the action of the second gear 403, the two driving shafts 402 can be rotated in opposite directions. When the driving shaft 402 drives the connecting arm 311 to rotate, the arc disk 313 can be controlled to expand and merge, and the size of the opening of the arc disk 313 is large, which is convenient for the entry and removal of trees. When the trees are located in the arc disk 313, the driving motor 401 is controlled to reverse, so that the arc disk 313 merges to surround the trees, and then the trees can be fumigated and insecticidal. Fig.11 , Fig.12 and Fig.13 The device is shown in working state and the arc-shaped disk 313 is in the unfolded and stored state.

[0046] like Figure 1 As shown, as another preferred embodiment of the present invention, a driving wheel set 5 is installed at the lower end of the mounting platform 1, and a control rod 501 is installed at the upper end of the mounting platform 1.

[0047] In actual application, the embodiment of the present invention can facilitate the movement of the device through the action of the driving wheel group 5 and the control rod 501, which is convenient for fumigating and killing insects in multiple forests.
