Description

Technical Field

[0001] The utility model relates to the technical field of pest control tools, in particular to a pesticide applicator for forest pest control. Background Art

[0002] Forests are one of Earth's most important natural resources and perform crucial ecological functions. However, due to excessive logging and inappropriate management, forest pests and diseases are becoming increasingly prominent. These diseases and pests severely damage the growth and reproduction of trees, disrupting the balance of the entire ecosystem. Preventing these pests and diseases is of vital importance to forest resources.

[0003] There are three common methods for applying pesticides to forest pests and diseases: trunk injection, spray application, and thermal fog. Spray application is currently the most widely used method due to its wide range of applications, ease of use, and high efficiency. Spray application primarily uses a sprayer to atomize the pesticide and then spray it onto the plant surface.

[0004] Conventional sprayers come in two types: electric and manual. Due to site limitations, batteries cannot be recharged quickly, and portability is key, so manual equipment is often used. In forests, access to water is not as convenient as in cities, often requiring access from mountain streams. Traditional sprayers require additional equipment and cannot be used autonomously, making them inconvenient to use. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A pesticide application device for preventing and controlling forest pests and diseases, comprising:

[0032] The liquid storage barrel 1 includes a barrel body 11, which is used to store liquid medicine. A booster component 2 is provided on one side of the top of the barrel body 11, and a water drawing component 3 is connected to the head of the booster component 2.

[0033] The barrel body 11 is made of plastic and is integrally formed. A shoulder strap 13 is mounted on the back of the barrel body 11 for the operator to carry the liquid storage barrel 1 on his back.

[0034] A barrel cover 12 is threadedly connected to one side of the top of the barrel body 11. The barrel cover 12 can be removed to carry out normal water collection and medicine mixing.

[0035] The bottom side of the barrel body 11 is connected to a nozzle 15 through a liquid outlet pipe 14 , and a switch 16 is provided between the nozzle 15 and the liquid outlet pipe 14 .

[0036] The switch 16 is a well-known ball valve, which can control the opening and closing of the nozzle 15 and the liquid outlet pipe 14 .

[0037] The boosting assembly 2 includes a piston assembly and a driving assembly. The driving assembly is used to drive the piston assembly to work. The piston assembly is inserted from the top of the barrel body 11.

[0038] The piston assembly includes an air cylinder 21, which is threadedly connected to the barrel body 11. A piston 22 is slidably installed in the air cylinder 21. A one-way piston seal 23 is provided on the side of the piston 22. The outer side of the one-way piston seal 23 is in contact with the inner wall of the air cylinder 21. The bottom of the air cylinder 21 is inserted into the barrel body 11 and is threadedly connected to a first one-way valve 26.

[0039] The outlet of the first one-way valve 26 faces the interior of the barrel 11 .

[0040] When the piston 22 moves upward, the air or water above the piston 22 can enter the bottom of the piston 22 through the gap between the one-way piston seal 23 and the air cylinder 21. When the piston 22 moves downward, the air or water below the piston 22 can enter the barrel body 11 through the first one-way valve 26.

[0041] The piston rod of the piston 22 passes through the top of the gas cylinder 21 upward.

[0042] The driving assembly includes a pressing handle 25, which is rotatably mounted on the bottom of the barrel body 11 and bent toward the back of the barrel body 11. A connecting rod 24 is rotatably mounted on the middle of the pressing handle 25, and the head of the connecting rod 24 is rotatably connected to the piston rod of the piston 22.

[0043] The pressing handle 25 is formed by bending a metal tube and is L-shaped as a whole. When the pressing handle 25 is rotated upward, the piston 22 can be driven to slide upward through the connecting rod 24. When the pressing handle 25 is rotated downward, the piston 22 can be driven to slide downward through the connecting rod 24.

[0044] The water drawing assembly 3 is rotatably mounted on the top side of the piston assembly. The water drawing assembly 3 includes a second one-way valve 31 , the outlet of the second one-way valve 31 is threadedly connected to the air cylinder 21 , and the inlet of the second one-way valve 31 is connected to a hard pipe 33 through a movable elbow 32 .

[0045] The second one-way valve 31 is threadedly mounted on the top of the air cylinder 21 on a side away from the shoulder strap 13 .

[0046] The movable elbow 32 is threadedly connected to the second one-way valve 31, and the hard pipe 33 is threadedly connected to the movable elbow 32. The hard pipe 33 can rotate around the axis of the second one-way valve 31 through the movable elbow 32.

[0047] When the piston 22 moves downward, the space above the piston 22 is in a negative pressure state, and the negative pressure can be transmitted to the hard pipe 33 through the second one-way valve 31 and the movable elbow 32.

[0048] A hose 34 is provided in the hard tube 33 . One end of the hose 34 is threadedly connected to a filter head 37 . The other end of the hose 34 is threadedly connected to the inner side of the bottom opening of the hard tube 33 through a first threaded sleeve 35 .

[0049] The first threaded sleeve 35 is engaged with the hose 34. When the hose 34 is located in the hard tube 33, it can be fixed by the threaded connection between the first threaded sleeve 35 and the hard tube 33 to prevent the hose 34 from slipping out of the hard tube 33.

[0050] When the hose 34 is located in the hard tube 33, the negative pressure generated by the downward movement of the piston 22 can allow external air to enter the piston 22 from the hose 34. At this time, the filter head 37 is used to filter impurities in the air to prevent large objects such as insects from entering the air cylinder 21.

[0051] A second threaded sleeve 36 is welded below the first threaded sleeve 35 , and the second threaded sleeve 36 is used for threaded connection with the outer side of the bottom of the hard tube 33 .

[0052] When the hose 34 is positioned outside the rigid tube 33, it can be threadedly connected to the rigid tube 33 using the second threaded sleeve 36 to secure it. The negative pressure generated by the downward movement of the piston 22 allows external water to enter the rigid tube 33 through the hose 34 and ultimately into the air cylinder 21. Water can be drawn from any location by adjusting the position of the filter head 37, which is used to filter impurities from the water.

[0053] A buckle 38 is clamped at the middle portion of the outer side of the second threaded sleeve 36 , and the buckle 38 is fixedly connected to the barrel body 11 by screws.

[0054] When the hose 34 is located in the hard tube 33 , the buckle 38 can be used to engage the second threaded sleeve 36 to fix the hard tube 33 , thereby preventing the hard tube 33 from rotating and affecting the application of the medicine.

[0055] When the operator of this embodiment uses the device, he turns off the switch 16, places the barrel body 11 on the ground, unscrews the barrel cover 12, introduces the medicine into the barrel body 11, and then tightens the barrel cover 12.

[0056] The second threaded sleeve 36 is disengaged from the buckle 38 , and then the hard tube 33 is rotated to a horizontal state.

[0057] The second threaded sleeve 36 is rotated to drive the first threaded sleeve 35 to rotate, so that the first threaded sleeve 35 is separated from the hard tube 33, and the hose 34 is pulled out from the hard tube 33. Then the direction is reversed and the second threaded sleeve 36 is threadedly connected to the hard tube 33.

[0058] Insert the filter head 37 into the water.

[0059] The pressing handle 25 is driven to rotate up and down, and the piston 22 is driven to reciprocate in the cylinder 21 through the connecting rod 24 .

[0060] When the piston 22 moves downward, the space above the piston 22 is in a negative pressure state. The negative pressure generated by the downward movement of the piston 22 can allow external water to enter the hard tube 33 through the hose 34 and finally enter the air cylinder 21.

[0061] When the piston 22 moves upward, the air or water above the piston 22 can enter the bottom of the piston 22 through the gap between the one-way piston seal 23 and the air cylinder 21.

[0062] When the piston 22 moves downward again, the water below the piston 22 can be pressed into the barrel body 11 through the first one-way valve 26. The water drawing is completed.

[0063] After the water is pumped out, the connection between the second threaded sleeve 36 and the hard pipe 33 is released, and the hose 34 is inserted into the hard pipe 33. The first threaded sleeve 35 is then threadedly connected to the hard pipe 33 to secure the hose 34, preventing it from slipping out of the hard pipe 33. Finally, the second threaded sleeve 36 is engaged with the buckle 38 to secure the hard pipe 33.
