[0026] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0027] As Figure 1 shown, the utility model provides a kind of portable spray prevention and treatment device, comprising:
[0028] Swing arm 1, spray head 2 and medicine box.
[0029] Spray head 2 is rotatably installed on one end of swing arm 1 by first rotating shaft 4, and a driving assembly is arranged on swing arm 1, which is used to drive spray head 2 to swing about swing arm 1 to change the spraying range of spray head 2.
[0030] The other end of swing arm 1 is connected with medicine box, and a communication pipe 3 for connecting medicine box and spray head 2 is arranged on swing arm 1.
[0031] By rotatably installing between spray head 2 and swing arm 1, and using driving assembly to drive spray head 2 to rotate about swing arm 1, when user sprays pesticide, spray head 2 can be driven to reciprocate by driving assembly during walking and spraying, so as to expand the spraying range of spray head 2, and the user does not need to drive swing arm 1 to reciprocate, saving the physical strength of the user.
[0032] In order to realize the driving action of the above-mentioned driving assembly to spray head 2, in the embodiment, referring to Figure 2 and Figure 3 shown, the driving assembly includes a second rotating shaft 6 rotatably mounted on the swing arm 1, a first transmission wheel 5 and a second transmission wheel 7 are respectively mounted on the first rotating shaft 4 and the second rotating shaft 6, and a transmission belt 8 is commonly sleeved on the first transmission wheel 5 and the second transmission wheel 7.
[0033] During the pesticide spraying process by the spray head 2, the user drives the second rotating shaft 6 to alternately rotate in the forward direction and the reverse direction, the second rotating shaft 6 drives the first rotating shaft 4 to synchronously rotate in the forward direction and the reverse direction through the transmission of the first transmission wheel 5, the second transmission wheel 7 and the transmission belt 8, thereby expanding the spraying range of the spray head 2.
[0034] During the pesticide spraying process by the spray head 2, the user needs to alternately drive the second rotating shaft 6 to rotate in the forward direction and the reverse direction in order to expand the spraying range of the spray head 2, and the strength of the user driving the second rotating shaft 6 to rotate in the forward direction and the reverse direction cannot be accurately grasped, thereby possibly causing the spray head 2 to unevenly spray the pesticide on the left and right sides. In order to solve the above problem, the following scheme is proposed:
[0035] In the embodiment, as shown in Figure 2 , a third rotating shaft 9 is rotatably installed on the swing arm 1, a half gear 10 is installed on the third rotating shaft 9, a gear 11 is installed on the second rotating shaft 6, and the half gear 10 meshes with the gear 11.
[0036] A disc spring 12 is arranged between the second rotating shaft 6 and the swing arm 1.
[0037] The user drives the third rotating shaft 9 to unidirectionally rotate, when the half gear 10 meshes with the gear 11, the third rotating shaft 9 drives the second rotating shaft 6 to rotate through the transmission of the half gear 10 and the gear 11, thereby driving the spray head 2 to swing, and along with the rotation of the second rotating shaft 6, the disc spring 12 accumulates energy, when the toothless area of the half gear 10 approaches the gear 11, the half gear 10 is separated from the gear 11, under the elastic force of the disc spring 12, the second rotating shaft 6 reversely rotates, the spray head 2 reversely swings, and so on, the user only needs to unidirectionally drive the third rotating shaft 9 to rotate, which can drive the spray head 2 to periodically and reciprocally swing, and can ensure the uniformity of the pesticide spraying on the left and right sides of the spray head 2.
[0038] When different plants are planted, the spacing is large or small, therefore, when the plants are sprayed with pesticide, the spraying range of the spray head 2 on the left and right sides is not the same, in order to avoid the waste of pesticide, as shown in Figure 2 and Figure 4 , in the embodiment:
[0039] At least two third rotating shafts 9 are arranged on the swing arm 1, a half gear 10 is installed on each third rotating shaft 9, and the diameters of each half gear 10 are different, the different diameters of the half gears 10, i.e. the different lengths of the half gears 10 driving the gear 11 to rotate, thereby making the swing amplitude of the spray head 2 different, thereby the spraying range of the spray head 2 can be changed.
[0040] The third rotating shaft 9 and the swing arm 1 are provided with a spring 13. Under the elastic force of the spring 13, the half gear 10 on the third rotating shaft 9 is separated from the gear 11. When the corresponding half gear 10 is selected, the user presses the corresponding third rotating shaft 9, so that the half gear 10 on the corresponding third rotating shaft 9 is engaged with the gear 11. The third rotating shaft 9 which is not pressed is separated from the gear 11 under the elastic force of the spring 13.
[0041] In the embodiment, the motor is arranged on the swing arm 1, and the motor is used to drive the third rotating shaft 9 to rotate. The motor is matched with the power supply, and the motor is used to drive the third rotating shaft 9 to rotate, so that the physical strength of the user can be further saved.
[0042] In the embodiment, the control switch is arranged on the communicating pipe 3. The opening degree of the communicating pipe 3 is controlled by the control switch, so as to change the flow of the medium in the communicating pipe 3.
[0043] The above embodiments are only exemplary embodiments of the application, and are not used to limit the application. The protection scope of the application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the application within the spirit and protection scope of the application. The modification or equivalent replacement is also regarded as falling within the protection scope of the application.
