Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a knapsack sprayer. Referring to fig. 1 and 2, including box 1, fixedly connected with connecting pipe 2 on the vertical lateral wall of box 1, connecting pipe 2 and box 1 intercommunication. One end of the connecting pipe 2, which is far away from the box body 1, is provided with a storage part 4 for storing pesticide, and a blocking part 3 for preventing pesticide from flowing into the connecting pipe 2 is arranged between the connecting pipe 2 and the storage part 4. Different kinds of pesticides can be placed in the box body 1 and the storage piece 4, so that different kinds of pesticides can be sprayed in sequence.

Referring to fig. 2 and 3, the storage member 4 includes three storage tanks 41 stacked on each other in the vertical direction, each storage tank 41 is cylindrical, and the storage tank 41 at the lowermost end is detachably connected to the blocking member 3. The lower extreme of storage tank 41 is feed end 411, and the upper end of storage tank 41 is discharge end 412, and the feed end 411 of storage tank 41 is seted up and is supplied the male opening of discharge end 412, and discharge gate 4121 has been seted up to the discharge end 412 terminal surface of storage tank 41, and the sealing ring 4122 that the discharge end 412 terminal surface fixedly connected with of storage tank 41 was made by the silica gel material, and sealing ring 4122 encircles in discharge gate 4121. The circumferential outer side wall of the feed end 411 of a storage tank 41 is in threaded connection with the circumferential inner side wall of the discharge end 412 of an adjacent storage tank 41. Fixedly connected with division board 5 in the storage tank 41, division board 5 falls into two cavities with the storage tank 41 inner chamber, has seted up a plurality of discharge opening 51 along circumference interval on the division board 5. The inner wall of the storage tank 41 and the partition plate 5 form a cavity for storing pesticides, the pesticides are poured into the storage tank 41 through the opening, then the storage tanks 41 are sequentially stacked, meanwhile, the adjacent storage tanks 41 are in threaded connection, so that the sealing ring 4122 on the discharge end 412 of the storage tank 41 above is tightly attached to the partition plate 5 in the storage tank 41 below, the discharge port 4121 can be sealed by the partition plate 5, and different types of pesticides can be stored in each storage tank 41 in advance.

Referring to fig. 2 and 3, the feed end 411 of the uppermost storage tank 41 is provided with a sealing cap 6 for closing the feed end 411, and the sealing cap 6 is threadedly coupled to the inner side wall of the discharge end 412. After the pesticide is poured into the discharge tank, the sealing cover 6 is screwed into the uppermost storage tank 41, so that the storage tank 41 is sealed, and the pesticide is prevented from leaking out as much as possible

Referring to fig. 2 and 3, the barrier 3 includes a barrier plate 31, a support spring 32, a support ring 7, a sealing plate 33 for closing the discharge hole 4121, and a fixing ring 34. The blocking plate 31 is fixedly connected to the end of the connecting pipe 2 far away from the box body 1, and the blocking plate 31 is communicated with the opening of the connecting pipe 2. Support ring 7 fixed connection is in the one side that baffling plate 31 deviates from connecting pipe 2, and support ring 7 has seted up the groove 71 of stepping down along circumference in the one side that baffling plate 31 deviates from, and supporting spring 32's one end fixed connection is on the diapire of groove 71 of stepping down. The sealing plate 33 is fixedly connected to one end of the supporting spring 32 far away from the supporting ring 7, and the sealing plate 33 and the supporting spring 32 are arranged coaxially. Fixed ring 34 is fixedly connected to one side of baffle plate 31 departing from connecting pipe 2, and discharge end 412 of storage tank 41 is in threaded connection with the circumferential inner side wall of fixed ring 34.

After the discharge end 412 of the storage tank 41 is screwed into the fixing ring 34, the sealing plate 33 tightly abuts against the sealing ring 4122 under the action of the supporting spring 32, so that the pesticide is limited to flow out of the discharge hole 4121; when the pesticide needs to be poured into the box body 1, the storage tank 41 is rotated to move upwards, so that the sealing plate 33 cannot seal the discharge hole 4121 any more, and the pesticide flows out of the discharge hole 4121, flows into the connecting pipe 2 and finally flows into the box body 1; after the pesticide in the lowermost storage tank 41 is consumed, the storage tank 41 adjacent to the lowermost storage tank 41 is rotated, and the partition plate 5 no longer seals the discharge hole 4121, so that the pesticide in the next storage tank 41 enters the connecting pipe 2 through the lowermost storage tank 41, and so on until the pesticide in the uppermost storage tank 41 is sprayed.

Referring to fig. 2, a plurality of filter holes 72 are circumferentially spaced on the circumferential outer side wall of the support ring 7. The pesticide can enter the connecting pipe 2 through the filtering holes 72 on the support ring 7, thereby reducing the entry of impurities into the connecting pipe 2.

Referring to fig. 2 and 3, a fixing rod 8 is hinged to the outer side wall of each storage tank 41, and a fixing block 9 is fixedly connected to the outer side wall of each storage tank 41. The fixed slot 91 that supplies dead lever 8 card to go into is seted up along vertical direction to the lateral wall of fixed block 9, and equal fixedly connected with is hemispherical fixture block 92 on two inside walls in opposite directions of fixed slot 91, and fixture block 92 is made by the silica gel material. After the fixing rod 8 is snapped into the fixing groove 91, the two latching blocks 92 can restrict the fixing rod 8 from being separated from the fixing groove 91. The fixing rod 8 on the storage tank 41 is clamped into the fixing groove 91 on the adjacent storage tank 41 above, so that the storage tank 41 at the uppermost end can drive all the storage tanks 41 to rotate together, and further the storage tank 41 at the lowermost end and the barrier 3 rotate; when the adjacent material storage tanks 41 need to rotate relatively, the fixing rods 8 on the lower material storage tank 41 are taken out from the fixing blocks 9 on the upper material storage tank 41, so that the two material storage tanks 41 can rotate relatively.

The implementation principle of the knapsack sprayer in the embodiment of the application is as follows: when spraying insecticide, put into a pesticide in box 1 earlier, pack into each storage tank 41 respectively with other kinds of pesticides after that, after the pesticide in box 1 consumed up, rotate storage tank 41, the pesticide in the storage tank 41 can flow into in the box 1 through connecting pipe 2 to be convenient for the vegetable grower continues to spray different pesticides, and labour saving and time saving effectively reduces the circumstances emergence that the pesticide mixes.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
