Detailed Description

As shown in fig. 1 to 11, a knapsack formula pesticide sprinkler that can independently proportion, including box 1 and the baldric 15 of establishing in box 1 rear end, be equipped with in the box 1 and separate disconnected piece 5, be equipped with the medicine chamber 2 that is located the disconnected piece 5 top in the box 1, the water cavity 3, be equipped with the hybrid chamber 4 that is located the disconnected piece 5 below in the box 1, the front end that separates disconnected piece 5 is equipped with the spout, the spout internal slipping is furnished with first rack 6, be connected with first spring between first rack 6 and the spout, the left and right sides of separating the upper end of piece 5 is provided with the swivelling chute symmetrically, play feed cylinder 8, two swivelling chutes set up respectively in medicine chamber 2, the water cavity 3, play feed cylinder 8 and swivelling chute, hybrid chamber 4 intercommunication, be equipped with in the swivelling chute with box 1, first rack 6 matched with adjusts dosing mechanism 7.

The quantitative adjusting mechanism 7 comprises a lower disc 71 and an upper disc 72, wherein the lower disc 71 and the upper disc 72 are rotatably arranged in the rotary groove, the outer ring of the lower disc 71 is provided with a gear ring meshed with the first rack 6, one sides of the lower disc 71 and the upper disc 72, which are far away from the first rack 6, are respectively provided with a first through hole and a second through hole, a second spring is connected between the lower disc 71 and the upper disc 72, the lower end of the first through hole is provided with a sleeve 73, and the upper end of the lower disc 71 is provided with a barrel groove which is coaxial with the second through hole and can accommodate the sleeve 73 to slide up and down. The disc rotates under the above-mentioned setting can be taken through first rack, and lower disc takes the disc to rotate together, and first through-hole and play feed cylinder intercommunication, the quantitative material in sleeve, the first through-hole falls into the mixing chamber along a feed cylinder after that.

The quantitative adjusting mechanism 7 further comprises a fixing plate 76 arranged at the upper end of the rotary groove, a pressing plate 74 is arranged above the upper disc 72 in a fitting manner, a sliding rod 75 penetrating through the fixing plate 76 is arranged at the upper end of the pressing plate 74, a third spring connecting the pressing plate 74 and the fixing plate 76 is sleeved outside the sliding rod 75, an ejector rod 77 ejecting to the middle of the upper disc 75 vertically penetrates through the box body 1, threads are arranged at the upper end of the ejector rod 77, and nuts are screwed on the threads. The ejector rod can be moved up and down by rotating the nut, the upper disc is moved up and down by the ejector rod under the action of the second spring, so that the capacity in the sleeve and the first through hole is changed, and the pressing plate can be always attached to the upper end face of the upper disc under the action of the third spring, so that the quantitative quantity adjusting effect is achieved.

When the lower disc 71 and the upper disc 72 rotate at a certain angle, the second through hole is not communicated with the discharging barrel 8 and the first through hole is completely covered by the pressing plate 74. When preventing first through-hole, second through-hole, play feed cylinder intercommunication, first through-hole also communicates with medicine chamber, water cavity, leads to the material streamer in medicine chamber, the water cavity.

When the lower disc 71 and the upper disc 72 rotate for half a turn, the second through hole is communicated with the discharging barrel 8.

The lower extreme of sleeve 8 that is located the right side is equipped with horizontal bar 9, is equipped with (mixing) shaft 10 on horizontal bar 9 with rotating, and the lower extreme circumference equipartition of (mixing) shaft 10 has stirring vane 11, and the upper end key joint of (mixing) shaft 10 has gear 14, and the front end of first rack 6 is equipped with pressing piece 12, and the rear end of pressing piece 12 is equipped with the second rack 13 that is located first rack 6 below and meshes with gear 14. As long as press down once the pressing piece, quantitative pesticide, water fall into the mixing chamber, make the second rack lapse simultaneously, the second rack is with gear revolve, the gear area has the (mixing) shaft to rotate, the (mixing) shaft area has stirring vane to rotate, first rack antedisplacement under the effect of first spring after that, first rack passes through the pressing piece area second rack antedisplacement, the second rack passes through the gear area and the (mixing) shaft reversal to mix the stirring with pesticide and water evenly.

The working principle is as follows: the outlet below the mixing cavity is connected with a spray gun, pesticide and water are respectively injected into the pesticide cavity and the water cavity through an injection port, then the ejector rod is required to move up and down through a rotating nut, the ejector rod enables the upper disc to move up and down under the action of a second spring, so that the capacity in the sleeve and the first through hole is changed, the pressing plate can be always attached to the upper end surface of the upper disc under the action of a third spring, the effect of adjusting the amount of pesticide and water mixed each time is achieved, before spraying is required, the pressing piece is pressed, the pressing piece drives the first rack to move back, the first rack drives the lower disc to rotate, the lower disc drives the upper disc to rotate together, then the first through hole is communicated with the discharge cylinder, the sleeve, the quantitative pesticide in the first through hole and the water fall into the mixing cavity along the discharge cylinder, meanwhile, the pressing piece drives the second rack to move back, the second rack rotates along with the gear, and, stirring shaft area stirring vane rotates, first rack antedisplacement under the effect of first spring after that, first rack area down the disc reversal reset, lower disc area goes up the disc reversal and resets, first rack passes through pressing piece area second rack antedisplacement, the second rack passes through gear area and has the (mixing) shaft reversal, thereby mix the stirring with pesticide and water, the liquid medicine of misce bene passes through the spray gun blowout after that, accomplish and mix now, and have the effect of adjusting quantitative volume.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
