Description

TECHNICAL FIELD

[0001] The utility model relates to the field of public health pest control, especially relates to an environmental protection type four-harm control pesticide spraying device. BACKGROUND

[0002] In the field of public health pest control, pest control work in epidemic and disaster areas of insect-borne diseases is very important. For a long time, traditional backpack pesticide spraying equipment has been widely used in such work. However, with the in-depth development of control work and the continuous improvement of operation efficiency and quality requirements, the disadvantages of traditional backpack equipment have become increasingly prominent.

[0003] The backpack design requires the operator to carry the equipment for a long time, which not only greatly increases the physical consumption of the operator, causing him to feel tired in a short time, but also seriously limits the rapid movement of the equipment in a large area. When a large area of the epidemic or disaster area needs to be efficiently controlled, this design cannot meet the demand of rapid coverage, greatly reducing the efficiency of the control work.

[0004] The more prominent problem is that the water pipe is inconvenient to store. During operation, the water pipe is often dragged at will and easily entangled with obstacles in the surrounding environment. This frequent entanglement not only greatly shortens the service life of the water pipe, requiring frequent replacement and causing a lot of resource waste, but also the waste water pipe generated during replacement becomes a new environmental pollutant. Especially in the densely populated epidemic area of insect-borne diseases, the messy water pipe not only affects the operation efficiency, but also may cause safety hazards to the daily life of residents.

The design of the rotary device allows the inclination angle of the spray head 71 to be adjusted according to the actual use requirements to meet the requirements of different spraying angles in different scenes, and the right side of the drug tank 3 is provided with a winding assembly.

[0025] As shown in Figures 3-6 The winding assembly includes a housing 8, a shaft 9, a spiral spring 10, a ratchet 11, a metal spring piece 12, a pawl 13 and a lever 131, the right side of the drug tank 3 is connected with the housing 8, the shaft 9 is rotatably connected in the housing 8, the excess part of the water pipe 6 is tightly wound on the shaft 9, the shaft 9 is further connected with the spiral spring 10 between the housing 8, the rear end of the shaft 9 is connected with the ratchet 11, the middle part of the housing 8 is connected with the metal spring piece 12 through a connecting piece, the tail end of the metal spring piece 12 is connected with the pawl 13, the pawl 13 is rotatably connected with the connecting piece, and the pawl 13 is connected with the ratchet 11 to fix the position of the shaft 9, the upper end of the pawl 13 is connected with the lever 131, the lever 131 penetrates out of the top of the housing 8, which is convenient for the operator to operate.

[0026] When the pest control operation is carried out in the epidemic area and disaster area of insect-borne disease, first, the cover 31 on the top of the medicine storage tank 3 is removed, the pesticide required for controlling pests is added into the medicine storage tank 3, after the addition of the pesticide is completed, the cover 31 is reconnected to the liquid inlet of the medicine storage tank 3, the device is pushed to the designated control site, the operator holds the spray rod 7, the water pipe 6 is pulled out from the shell 8, the movement of the water pipe 6 drives the rotation of the rotating shaft 9, in this process, the vortex spring 10 is deformed, at the same time, the rotation of the rotating shaft 9 drives the rotation of the ratchet 11, due to the special design of the connection angle between the ratchet 11 and the pawl 13, the ratchet 11 can pass the pawl 13 when rotating, the metal spring 12 provides a reset force for the pawl 13, after the water pipe 6 is pulled out to the required length, the ratchet 11 is connected with the pawl 13, which ensures that the ratchet 11 cannot be reversed, so that the water pipe 6 maintains the current length, then the water pump 5 is started, the water pump 5 sucks the pesticide in the medicine storage tank 3, and sends it to the spray rod 7 through the water pipe 6, and finally sprays out in the form of mist from the spray head 71. The operator holds the spray rod 7, adjusts the inclination angle of the spray head 71 according to the actual distribution of pests, and carries out pest control operation, after the operation is completed, when the water pipe 6 needs to be stored, the operator lifts the lever 131 to one side, the lever 131 drives the pawl 13 to rotate, so that the pawl 13 is disconnected with the ratchet 11, at this time, the metal spring 12 is deformed. The vortex spring 10 rebounds and resets due to the previous deformation, drives the rotating shaft 9 and the ratchet 11 to reverse, the rotating shaft 9 rewinds the water pipe 6, stores the excess part of the water pipe 6 into the shell 8, after the storage is completed, the lever 131 is loosened, the metal spring 12 drives the pawl 13 and the lever 131 to reset by relying on the elastic force of itself, the pawl 13 is reconnected with the ratchet 11, which prevents the water pipe 6 from being accidentally released.

[0027] As Figure 2 shown, it also includes a motor 4 and a stirring paddle 41, the lower left side of the medicine storage tank 3 is installed with the motor 4 through bolts, the output shaft of the motor 4 penetrates the inside of the medicine storage tank 3 and is connected with the stirring paddle 41, when the pesticide is injected into the medicine storage tank 3, the motor 4 is started, the rotating movement of the output shaft of the motor 4 is directly transmitted to the stirring paddle 41, which drives the stirring paddle 41 to continuously rotate in the medicine storage tank 3, through the stirring action of the stirring paddle 41, the activity of the pesticide in the medicine storage tank 3 can be effectively guaranteed, which avoids the phenomenon that the pesticide is deposited due to long-term standing, which affects the control effect, after the pesticide spraying operation is completed, the motor 4 is turned off in time, so as to save energy and avoid the idle loss of the equipment.

[0028] As Figure 7The spraying rod 7 is provided with the lifting handle 15, which is convenient for an operator to hold and further accurately control the position and angle of the spraying rod 7, greatly facilitates the development of the pesticide spraying operation, and can be flexibly adjusted in the installation position on the spraying rod 7 according to the use habits of different operators and actual operation requirements. The right side wall of the moving frame 1 is symmetrically connected with the elastic buckles 14 upward and downward. The spraying rod 7 can be firmly clamped between the two buckles 14, so as to realize reliable limiting and fixing of the spraying rod 7. When the spraying rod 7 needs to be disassembled, the operator only needs to moderately pull the spraying rod 7 outward, and the spraying rod 7 can be quickly and conveniently taken down by using the elastic deformation of the buckle 14 itself. The operation is simple and efficient.

[0029] Finally, it should be explained that the above examples are only used to illustrate the technical solutions of the present application, but not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
