Description

Technical Field

[0001] The invention relates to the technical field of forestry pest control, in particular to a ground powder spraying device for controlling harmful organisms. Background Art

[0002] With the continuous expansion of human activities, forest pests and diseases have become increasingly prominent, posing a serious threat to forest ecosystems. In order to protect forest resources and ensure the health and stability of the forest system, biological control of forest pests and diseases is particularly important. The bark beetle is a forest pest that mainly harms Pinus magnoliae. The insect spreads very quickly, is highly concealed, and is difficult to control. In order to effectively protect the safety of forest resources in Yunnan Province, timely and effective drug control of bark beetles and other pests is carried out. At the peak period of bark beetles turning from tips to trunks and flying, the adult beetles are killed to reduce the insect population density and reduce disaster losses, so as to save the damaged forest stands to the maximum extent.

[0003] Since bark beetles are borers, high-altitude control by drones alone cannot effectively kill bark beetles in the flying stage, especially for parts below the crown to the ground, and the drone control liquid cannot effectively penetrate into the tree trunk and the ground. Through research and experiments, it is shown that the combination of high-altitude control by drones and manual ground control is more effective than single drone control, which can effectively improve the killing rate of bark beetles. Traditional ground powder spraying devices are mostly carried out by workers carrying a box of pesticides for manual spraying, which consumes a lot of physical energy and labor. Most spraying devices also lack stirring measures, resulting in the inability to fully mix the pesticides. In addition, the traditional spraying device has a low spraying force for the pesticides and a limited operating range. Therefore, a ground powder spraying device for pest control is developed.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 4 As shown, a ground powder spraying device for pest control includes a base 1, and wheel frames 2 are fixedly installed at the four corners of the base 1. A running wheel 3 is rotatably installed at the lower end of each wheel frame 2. In addition, a driving motor for driving each running wheel to rotate is arranged at the bottom of the base.

[0027] A medicine storage box 4 and a turnover box 5 are fixedly installed on the upper part of the base 1. The bottom plate of the medicine storage box 4 is tilted downward in the direction close to the turnover box 5, and a vibrator (not shown in the figure) is arranged below the bottom plate of the medicine storage box 4. A support plate 6 for supporting the medicine storage box 4 is vertically fixedly arranged on the upper part of the base 1. One end of the lower part of the medicine storage box 4 is connected to the lower end of the turnover box 5 through a downward tilted material transfer channel 7.

[0028] In this embodiment, the upper end of the medicine storage box 4 is an open structure, and two movable cover plates 8 are symmetrically hingedly installed, and a handle with a U-shaped cross-section is fixedly installed on the upper part of each movable cover plate 8.

[0029] In addition, a horizontal stirring shaft 9 is rotatably installed in the middle of the medicine storage box 4, and a stirring motor 10 for driving the stirring shaft 9 to rotate is installed outside the medicine storage box 4.

[0031] Specifically: the turnover mechanism includes two groups of transmission wheels 14 symmetrically rotatably mounted on the upper and lower ends of the inner side wall of the turnover box 5 and a turnover motor 15 fixedly mounted on the outer side of the turnover box 5 for driving the four transmission wheels to rotate synchronously. The turnover motor 15 is mounted on the lower end of the turnover box 5 away from the medicine storage box 4. The driving shaft of the turnover motor 15 is connected to the central axis of the transmission wheel 14 close to it, and the central axes of the two transmission wheels 14 located on the upper part of the turnover box 5 are connected through a transmission shaft 16. The two transmission wheels 14 located on the same side are commonly mounted with a transmission belt 17 adapted thereto, and a plurality of L-shaped cross-section transport hoppers 18 are uniformly and fixedly arranged on the outer sides of the two transmission belts 17.

[0032] A rotating tube 19 is rotatably mounted in the middle of the boost cylinder 12, and a rotating tube motor 20 for driving the rotating tube 19 to rotate is fixedly mounted on the outside of the medicine storage box 4. An air compressor 21 is fixedly mounted on the outside of the turnover box 5, and the output end of the air compressor 21 is connected to one end of an air supply pipe 22, and the other end of the air supply pipe 22 is connected to the end of the rotating tube 19 close to the medicine storage box 4 through a rotating joint 23;

[0033] In this embodiment, a driving gear 24 is installed on the driving shaft of the rotating tube motor 20 , and a driven gear 25 meshing with the driving gear 24 is fixedly sleeved on the portion of the rotating tube 19 between the boost cylinder 12 and the rotating joint 23 .

[0034] The outer peripheral wall of the boost cylinder 12 is fixedly sleeved with a spiral blade 26, and the end of the boost cylinder 12 away from the rotary joint 23 is evenly provided with a plurality of air outlet holes 27. The end of the boost cylinder 12 away from the medicine storage box 4 is a cone cylinder structure and is connected to one end of the medicine spraying pipe 28, and the other end of the medicine spraying pipe 28 is connected to the nozzle 29.

[0035] As a further improvement of the present invention, a swing mechanism for driving the spray head 29 to swing back and forth is disposed at one end of the base 1 away from the medicine storage box 4 .

[0036] In this embodiment, the swing mechanism includes a mounting frame 30 fixedly mounted on the upper part of the base 1, the vertical part of the mounting frame 30 is fixedly connected to the base 1, a swing motor 31 is fixedly mounted on the bottom of the free end of the horizontal part of the mounting frame 30, and the driving shaft of the swing motor 31 is fixedly connected to one end of a connecting rod 32. A vertical mounting shaft 33 is fixedly mounted on the upper part of the other end of the horizontal part of the mounting frame 30, the upper part of the mounting shaft 33 is rotatably connected to one end of a swing rod 34, a connecting sleeve 35 is slidably sleeved on the swing rod 34, the bottom of the connecting sleeve 35 is rotatably connected to the upper part of the other end of the connecting rod 32, a fixing ring 36 is fixedly arranged on the other end of the swing rod 34, and the main body of the nozzle 29 is fixedly mounted on the fixing ring 36.

[0038] When the present invention is working, the wettable powder for placing bark beetles is put into the medicine storage box, and the stirring shaft is driven to rotate by the stirring motor, so that the stirring blades stir and mix the powder medicine in the medicine storage box. Since the bottom plate of the medicine storage box is in an inclined state, the powder medicine at the bottom moves towards each other and enters the turnover box through the inclined material transfer channel. Under the action of the turnover motor, the powder medicine at the bottom of the turnover box is shoveled by the transfer hopper, and moves with the transfer hopper to the top of the two upper transmission wheels. When the transfer hopper flips downward, the powder medicine falls into the booster cylinder below under the action of gravity, thereby completing the automatic transportation of the medicine.

[0039] Under the action of the rotating tube motor, the spiral blades outside the rotating tube rotate with the rotating tube, and the rotating spiral blades convey the medicine forward to the conical opening end of the booster tube. During the conveying process, the rotating spiral blades also pressurize the medicine. The high-pressure air provided by the air compressor enters the rotating tube through the air supply pipe and is sprayed out from the air outlet at the end of the rotating tube. The high-pressure air mixed with the powder medicine enters the spraying tube and is sprayed out from the nozzle, thereby effectively increasing the spraying pressure of the powder.

[0040] In addition, the present invention drives the connecting rod to rotate by means of a swing motor, and under the action of the connecting sleeve, the swing rod drives the spray head to swing back and forth, thereby increasing the spraying range of the spray head.

[0041] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
