DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0033] Example 1

[0034] A spraying device for water emulsion pesticides, such as Figures 1-12 As shown, it includes a medicine storage box 1, a shoulder strap 2, a sprayer 3, an adding cover 4, a breaking mechanism 5 and a quantitative mechanism 6. Two shoulder straps 2 are connected to the front of the medicine storage box 1, the sprayer 3 is connected to the lower left part of the medicine storage box 1, the adding cover 4 is threadedly connected to the upper right part of the medicine storage box 1, and the upper left part of the medicine storage box 1 is provided with a breaking mechanism 5, through which the water emulsion pesticide bottle 55 can be automatically broken open so that the water emulsion can be poured into the medicine storage box 1. The lower left part of the medicine storage box 1 is provided with a quantitative mechanism 6, through which the water emulsion can be quantitatively poured, so that the pesticide can be proportioned according to people's needs.

[0035] like Figures 1-5 As shown, the breaking mechanism 5 includes a breaker 51, a sliding frame 52, a pressing frame 53 and a first spring 54. The breaker 51 is connected to the left part of the medicine storage box 1, and an oblique sharp knife is arranged in the front part of the breaker 51. When the water-emulsified pesticide bottle 55 moves down and contacts the oblique sharp knife of the breaker 51, the breaker 51 can automatically break the water-emulsified pesticide bottle 55. The upper rear part of the breaker 51 is slidably connected to the sliding frame 52 for placing the water-emulsified pesticide bottle 55, and the upper part of the sliding frame 52 is slidably connected to the pressing frame 53 that is squeezed and matched with the water-emulsified pesticide bottle 55. The water-emulsified pesticide bottle 55 is pressed downward by the pressing frame 53, and the lower part of the pressing frame 53 and the upper part of the water-emulsified pesticide bottle 55 are snap-fitted. The front lower part of the sliding frame 52 is provided with a straight groove that matches the oblique sharp knife, and the upper part of the pressing frame 53 and the top of the sliding frame 52 are connected with a first spring 54 wound on the pressing frame 53.

[0036] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown in the figure, the metering mechanism 6 includes a livestock medicine bin 61, a piston cylinder 62, a piston rod 63, a first one-way valve 64 and a second one-way valve 65. The lower part of the breaker 51 is connected to and communicates with the livestock medicine bin 61. The livestock medicine bin 61 is used for storing the emulsion. The lower side of the left rear part of the medicine storage box 1 is connected to and communicates with the piston cylinder 62 which is connected to the livestock medicine bin 61. The first one-way valve 64 is connected to the upper front part of the piston cylinder 62, and the second one-way valve 65 is connected to the front part of the piston cylinder 62. The piston rod 63 which slides inside the piston cylinder 62 passes through the medicine storage box 1. Moving the piston rod 63 backward will draw the emulsion in the livestock medicine bin 61 into the piston cylinder 62. A scale value is set at the top of the piston rod 63.

[0037] When people use the spraying device for emulsion pesticides to spray pesticides, they can first mix the pesticides. Move the pressing frame 53 upward first, and the first spring 54 is stretched. Then place the emulsion pesticide bottle 55 on the sliding frame 52. The upper part of the emulsion pesticide bottle 55 is stuck under the pressing frame 53. Then release the pressing frame 53. Under the action of the first spring 54, the pressing frame 53 can limit the emulsion pesticide bottles 55 at different heights. Then press the pressing frame 53, and the pressing frame 53 will drive the emulsion pesticide bottle 55 to move downward. The emulsion pesticide bottle 55 will drive the sliding frame 52 to move downward together. The downward movement of the sliding frame 52 will cause the inclined sharp knife to insert into the position of the straight slot. As the emulsion pesticide bottle 55 moves downward, the inclined sharp knife can automatically break open the emulsion pesticide bottle 55. In this way, the emulsion in the emulsion pesticide bottle 55 will flow downward into the livestock medicine bin 61 for collection. After the emulsion is poured out, the sliding frame 52 can be moved upward to drive the pressing frame 53 and the emulsion pesticide bottle 55 to move upward and reset. Then the emulsion pesticide bottle 55 can be taken out forward. Then, according to the requirement of the mixing ratio, move the piston rod 63 backward to extract the emulsion. Under the action of the first one-way valve 64, the emulsion in the livestock medicine bin 61 is drawn into the piston cylinder 62 unidirectionally. Under the action of the second one-way valve 65, the pesticide inside the medicine storage box 1 will not flow back into the piston cylinder 62. During the process of pulling the piston rod 63, people can know the amount of the extracted emulsion by checking the scale value on the piston rod 63, so as to facilitate the mixing of pesticides. After extracting the required amount of emulsion, stop pulling the piston rod 63. Then the piston rod 63 can be moved forward. At this time, the metered emulsifier will enter the medicine storage box 1 through the second one-way valve 65. In this way, it is convenient to quantitatively inject the emulsifier into the medicine storage box 1, so as to facilitate the mixing of pesticides. Then people can carry the backpack strap 2 and turn on the sprayer 3 to spray pesticides.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, as Figure 2 、 Figure 8 and Figure 9As shown in the figure, it further includes a spreading mechanism 7 for conveniently spreading the crack of the emulsion pesticide bottle 55 to accelerate the downward flow of the emulsion. The spreading mechanism 7 includes a guide sleeve 71, a rotating frame 72, a lifting frame 73 and a second spring 74. The front lower part of the breaker 51 is connected with the guide sleeve 71. The lifting frame 73 which is in extrusion fit with the bottom of the sliding frame 52 is slidably connected to the guide sleeve 71. A second spring 74 is connected between the front upper part of the lifting frame 73 and the top of the guide sleeve 71. The front lower part of the breaker 51 is rotatably connected with a rotating frame 72 for spreading the crack of the emulsion pesticide bottle 55. The inclined sharp knife is rotatably connected with the rotating frame 72. The front upper part of the lifting frame 73 is movably connected with the front part of the rotating frame 72. After the sliding frame 52 moves downward to contact the lifting frame 73, the lifting frame 73 drives the rotating frame 72 to rotate.

[0040] When the sliding frame 52 drives the emulsion pesticide bottle 55 to move downward, after the emulsion pesticide bottle 55 is broken by the inclined sharp knife, the rear part of the rotating frame 72 is inserted into the crack of the emulsion pesticide bottle 55 that is broken. When the sliding frame 52 moves downward, it will contact the lifting frame 73 and drive the lifting frame 73 to move downward. The second spring 74 is compressed. When the lifting frame 73 moves downward, it will rotate the rotating frame 72. The rotation of the rotating frame 72 will spread the crack of the emulsion pesticide bottle 55. In this way, the flow rate of the emulsion can be accelerated so as to pour the emulsion more quickly. After the sliding frame 52 drives the emulsion pesticide bottle 55 to move upward, the sliding frame 52 is separated from the lifting frame 73. Under the action of the second spring 74, the lifting frame 73 is driven to move upward and reset, driving the rotating frame 72 to reverse and reset.

[0041] As Figure 2 and Figure 10 shown in the figure, it further includes a mixing mechanism 8 for accelerating the mixing of the emulsion and other pesticides. The mixing mechanism 8 includes a support block 81, an impeller 82, a spatial cam 83 and a sliding rod 84. The front side of the bottom of the piston cylinder 62 is connected with the support block 81. The impeller 82 is rotatably connected to the middle of the support block 81. A spatial cam 83 is connected to the rear part of the impeller 82. The rear lower part of the piston rod 63 is connected with a sliding rod 84 that is in threaded fit with the spatial cam 83. The movement of the piston rod 63 drives the sliding rod 84 to move, and the spatial cam 83 drives the impeller 82 to rotate.

[0042] When the piston rod 63 is moved backward, it will drive the sliding rod 84 to move backward. The sliding rod 84 will drive the spatial cam 83 to rotate, and the spatial cam 83 will drive the impeller 82 to rotate. When the piston rod 63 is moved forward, it will also drive the sliding rod 84 to move forward and drive the impeller 82 to rotate at the same time. At this time, the emulsion just sprays out from the front part of the piston cylinder 62. The rotation of the impeller 82 can disperse the emulsion and mix it into the pesticide. In this way, it is convenient to mix the emulsion and other pesticides together.

[0043] As Figure 1 、 Figure 2 andFigure 11 As shown, it further includes a splash-proof mechanism 9 that can prevent the emulsion from splashing onto people's skin. The splash-proof mechanism 9 includes a telescopic tube 91, a support ring 92, and a rotating block 93. The upper left part of the medicine storage tank 1 is connected with a telescopic tube 91 that sleeves outside the sliding frame 52 and the emulsion pesticide bottle 55. The top of the telescopic tube 91 is connected with a support ring 92. The upper rear part of the support ring 92 is rotatably connected with a rotating block 93 that is clamped and matched with the upper rear part of the sliding frame 52. After the support ring 92 moves upward, the telescopic tube 91 is unfolded to block the emulsion pesticide bottle 55.

[0044] After the emulsion pesticide bottle 55 is placed well, the support ring 92 and the rotating block 93 are moved upward, the telescopic tube 91 is unfolded, the rotating block 93 is moved upward to the top of the sliding frame 52, and the rotating block 93 is rotated and clamped at the top position of the sliding frame 52. In this way, the telescopic tube 91 can block the emulsion pesticide bottle 55. In this way, whether the emulsion pesticide bottle 55 is cut for feeding or the emulsion pesticide bottle 55 is moved upward, the telescopic tube 91 can prevent the emulsion from splashing everywhere. When the emulsion pesticide bottle 55 needs to be taken out, the rotating block 93 is reversed and separated from the sliding frame 52, and then the support ring 92 and the rotating block 93 are moved downward to reset, and the telescopic tube 91 is retracted.

[0045] As Figure 1 、 Figure 2 and Figure 12 As shown, it further includes a locking mechanism 10. The locking mechanism 10 includes a support sleeve 101, a rotating buckle 102, and a torsion spring 103. The support sleeve 101 is connected to the upper front part of the breaker 51. The inside of the support sleeve 101 is rotatably connected with a rotating buckle 102 that is in extrusion fit with the sliding frame 52. The torsion spring 103 is connected between the lower part of the rotating buckle 102 and the bottom of the support sleeve 101.

[0046] Before moving the emulsion pesticide bottle 55 downward, the rotating buckle 102 can be rotated 90 degrees, the torsion spring 103 is twisted, and then the sliding frame 52 is moved downward to make the emulsion pesticide bottle 55 move downward for breaking. When the sliding frame 52 moves downward to the limit, the rotating buckle 102 is released. Under the action of the torsion spring 103, the rotating buckle 102 is driven to rotate and reset to lock the sliding frame 52. In this way, the emulsion in the emulsion pesticide bottle 55 can be stably poured. After pouring is completed, the rotating buckle 102 can be rotated 90 degrees again to release the sliding frame 52, so as to pull the sliding frame 52 upward to reset, and then the rotating buckle 102 is released. Under the action of the torsion spring 103, the rotating buckle 102 is driven to rotate and reset.

[0047] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
