Description

Technical Field

[0001] The present invention relates to the technical field of forest pest control, and particularly to a ground powder spraying device for pest control. Background Art

[0002] With the continuous expansion of human activities, the problem of forest pests and diseases has become increasingly prominent, posing a serious threat to the forest ecosystem. In order to protect forest resources and ensure the health and stability of the forest system, the biological control of forest pests and diseases is particularly important. The bark beetle is a forest pest that mainly damages Pinus kesiya var. langbianensis. The spread speed of this insect is extremely fast, it has strong concealment, and it is difficult to control. To effectively protect the safety of forest resources in Yunnan Province and promptly and effectively carry out the drug control work on pests such as bark beetles, during the peak period of the bark beetle's transition from twigs to trunks and its flying, adult insects are killed to reduce the population density and minimize the disaster losses, so as to save the damaged forest stands to the greatest extent.

[0003] Since the bark beetle belongs to boring pests, using only drones for high-altitude control cannot effectively kill the bark beetles during the flying period. Especially for the parts from below the tree crown to the ground, the control liquid of the drone cannot effectively penetrate into the tree trunk and the ground. Through research and experiments, it is shown that the method of combining high-altitude control by drones and ground control by humans for bark beetle control has a better effect than using only drones for control, and can effectively improve the killing rate of bark beetles. Most traditional ground powder spraying devices are manually sprayed by workers carrying medicine boxes, which consumes a large amount of physical strength and labor. Most spraying devices also lack stirring measures, resulting in the medicine not being fully mixed, and the traditional spraying devices have a low spraying force for the medicine and a limited working range. Therefore, a ground powder spraying device for pest control is developed. Summary of the Invention

Detailed implementation manners

[0026] As Figures 1-4 shown, a ground powder spraying device for pest control includes a base 1. At the four corner positions of the base 1, wheel frames 2 are respectively fixedly installed. At the lower ends of the wheel frames 2, running wheels 3 are rotatably installed. In addition, a driving motor for driving the rotation of each running wheel is provided at the bottom of the base.

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

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

[0029] In addition, a horizontal stirring shaft 9 is rotatably installed in the middle of the interior of the medicine storage box 4, and a stirring motor 10 for driving the rotation of the stirring shaft 9 is installed outside the medicine storage box 4. A plurality of stirring blades 11 are fixedly installed on the stirring shaft 9 at equal intervals.

[0030] A horizontal pressurizing cylinder 12 is fixedly installed on the turnover box 5. A material transfer hopper 13 communicating with the inside thereof is installed at the part of the pressurizing cylinder 12 located inside the turnover box 5. And a turnover mechanism for transferring the powder medicine from its bottom to the material transfer hopper 13 is arranged inside the turnover box 5.

[0031] Specifically: The turnover mechanism includes two groups of symmetrically arranged driving wheels 14 rotatably installed at the upper and lower ends of the inner side wall of the turnover box 5 and a turnover motor 15 fixedly installed outside the turnover box 5 for driving the synchronous rotation of the four driving wheels. The turnover motor 15 is installed at the lower end of the side 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 driving wheel 14 closest to it. The central axes of the two driving wheels 14 located in the upper part of the turnover box 5 are connected by a transmission shaft 16. A transmission belt 17 adapted to them is commonly installed on the two driving wheels 14 on the same side. A plurality of L-shaped material transporting hoppers 18 with a uniform cross-section are fixedly arranged at equal intervals on the outer sides of the two transmission belts 17.

[0032] A rotating pipe 19 is rotatably installed in the middle of the pressurizing cylinder 12. A rotating pipe motor 20 for driving the rotation of the rotating pipe 19 is fixedly installed outside the medicine storage box 4. An air compressor 21 is fixedly installed outside the turnover box 5. The output end of the air compressor 21 is communicated with one end of an air supply pipe 22. The other end of the air supply pipe 22 is connected to one end of the rotating pipe 19 close to the medicine storage box 4 through a rotary joint 23;

[0033] In this embodiment, a driving gear 24 is installed on the driving shaft of the rotating pipe motor 20. A driven gear 25 meshing with the driving gear 24 is fixedly sleeved on the part of the rotating pipe 19 located between the pressurizing cylinder 12 and the rotary joint 23.

[0034] A spiral blade 26 is fixedly sleeved on the outer peripheral wall of the pressurizing cylinder 12. A plurality of air outlet holes 27 are uniformly opened at one end of the pressurizing cylinder 12 away from the rotary joint 23. One end of the pressurizing cylinder 12 away from the medicine storage box 4 is of a conical cylinder structure and is communicated with one end of a medicine spraying pipe 28. The other end of the medicine spraying pipe 28 is communicated with a spray head 29.

[0035] As a further improvement of the present invention, a swinging mechanism for driving the spray head 29 to swing reciprocally is arranged 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 installed on the upper part of the base 1. The vertical part of the mounting frame 30 is fixedly connected to the base 1. At the bottom of the free end of the horizontal part of the mounting frame 30, a swing motor 31 is fixedly installed. The drive shaft of the swing motor 31 is fixedly connected to one end of a connecting rod 32. At the upper part of the other end of the horizontal part of the mounting frame 30, a vertical mounting shaft 33 is fixedly installed. 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 at the other end of the swing rod 34. The main body of the spray head 29 is fixedly installed on the fixing ring 36.

[0037] In addition, the medicine spraying pipe 28 is specifically arranged as a telescopic corrugated pipe to meet the movement range of the spray head 29.

[0038] When the present invention works, the wettable powder for placing bark beetles is put into the medicine storage box. 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 thereof 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 material transfer hopper and moves together with the material transfer hopper above the upper two transmission wheels. When the material transfer hopper turns downward, the powder medicine falls into the lower pressure increasing cylinder under the action of gravity, thereby completing the automatic transfer of the medicine.

[0039] Under the action of the rotating pipe motor, the spiral blades outside the rotating pipe rotate together with the rotating pipe. The rotating spiral blades convey the medicine forward to the conical opening end of the pressure increasing cylinder. During the conveying process, the rotating spiral blades also increase the pressure of the medicine. And the high-pressure air provided by the air compressor enters the rotating pipe through the air supply pipe and is ejected from the air outlet holes at the end of the rotating pipe. The high-pressure air is mixed with the powder medicine and enters the medicine spraying pipe together and is ejected from the spray head, thereby effectively increasing the spraying pressure of the powder.

[0040] In addition, the present invention drives the connecting rod to rotate through the swing motor. Under the action of the connecting sleeve, the swing rod drives the spray head to swing reciprocally, 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 do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
