Abstract
The utility model relates to an autonomous recovery device for an overflowing liquid pesticide at a pesticide sprayer nozzle, which aims to solve the problems that the waste is caused because the overflowing liquid pesticide at the outlet of the traditional pesticide sprayer is not utilized, and moreover, the overflowing liquid pesticide is easy to generate environmental pollution and potential safety hazards also exist. The autonomous recovery device comprises a recovery cup (3) and a reflux pipe (4), wherein the recovery cup (3) is hermetically sheathed on the pesticide sprayer nozzle (1), and the upper edge of the recovery cup (3) is lower than that of the pesticide sprayer nozzle (1); the lower end of the side wall of the recovery cup (3) is provided with a diversion opening (3-1); one end of the reflux pipe (4) is hermetically connected with the diversion opening (3-1); and the other end of the reflux pipe (4) is hermetically connected with a pesticide sprayer pesticide chest (2). By adopting the autonomous recovery device, the utilization ratio of the pesticide and the using safety of the pesticide are effectively improved, and simultaneously, the environmental pollution is also reduced. The autonomous recovery device is suitable for various pesticide sprayers.
Description
Technical field
The utility model relates to the voluntary recall device of the excessive soup in a kind of spraying machine nozzle place, is specifically related to a kind of voluntary recall device that is used for the excessive soup in spraying machine nozzle place.
Background technology
Existing airborne wide range forest prevention and control of plant diseases, pest control spraying machine outlet all is simple thin cylinder shape structure, when spraying the medicine operation outlet of spraying machine with greater than the direction of 45 towards tree crown, the soup of atomizing sprays at a high speed from the spraying machine outlet and spills to tree crown, reaches the purpose of prevention and elimination of disease and pests.
The problem that the spraying machine outlet of above-mentioned form exists is: export the relative static pressure vanishing of moment that the higher atomizing soup of inner static pressure relatively sprays from outlet at spraying machine.Because the unexpected variation of static pressure and the thin-wall effect of outlet edge cause the soup air-flow diffusion of atomizing and produce local eddy currents at outlet edge relatively, and then cause the partly atomized soup to walk around the outer wall generation overflow of drug fluid that outlet edge flows to outlet.This part flows to the excessive soup of spraying machine outlet and does not obtain utilizing, and has caused waste, and in addition, excessive soup easily produces environmental pollution, also has potential safety hazard.
The utility model content
The purpose of this utility model is not obtain utilizing in order to solve the excessive soup of existing spraying machine outlet, caused waste, in addition, excessive soup easily produces environmental pollution, also there is the problem of potential safety hazard, and then a kind of voluntary recall device that is used for the excessive soup in spraying machine nozzle place is provided.
The technical solution of the utility model is: a kind of voluntary recall device that is used for the excessive soup in spraying machine nozzle place comprises recovery cup and return duct, reclaiming the cup sealing shroud is contained on the spraying machine nozzle, and the upper edge of reclaiming cup is lower than the upper edge of spraying machine nozzle, the lower end of reclaiming cup sidewall has flow-guiding mouth, one end and the flow-guiding mouth of return duct are tightly connected, and the other end of return duct and spraying machine medicine-chest are tightly connected.
The utility model compared with prior art has following effect: 1. spraying machine nozzle 1 excessive soup of the present utility model can be realized voluntary recall, effectively raises the security of utilization ratio of drug and drug use, has also reduced the pollution to environment simultaneously.2. the utility model is simple in structure, manufactures easily, and cost is low, is convenient to extensive use.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is the schematic diagram of the utility model voluntary recall process.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, a kind of voluntary recall device that is used for the excessive soup in spraying machine nozzle place of present embodiment comprises recovery cup 3 and return duct 4, reclaiming cup 3 sealing shrouds is contained on the spraying machine nozzle 1, and the upper edge of reclaiming cup 3 is lower than the upper edge of spraying machine nozzle 1, the lower end of reclaiming cup 3 sidewalls has flow-guiding mouth 3-1, one end and the flow-guiding mouth 3-1 of return duct 4 are tightly connected, and the other end of return duct 4 and spraying machine medicine-chest 2 are tightly connected.
Spraying machine nozzle 1 is arranged on the spraying machine medicine-chest 2.
The specific embodiment two: in conjunction with Fig. 1 present embodiment is described, the recovery cup 3 and the spraying machine nozzle 1 of present embodiment pass through welded seal.Good sealing effect so is set.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: in conjunction with Fig. 1 present embodiment is described, the distance H between the upper edge of the recovery cup 3 of present embodiment and the upper edge of spraying machine nozzle 1 is 5mm-20mm.So be provided with, since when spraying the medicine operation outlet of spraying machine with greater than the direction of 45 towards tree crown, make the excessive part soup of edge of spraying machine nozzle 1 can more drop in the recovery cup 3, not only effectively raise utilization rate to medicine, and, also reduced pollution to environment to the security of drug use.Other composition is identical with the specific embodiment one with annexation.
The course of work of present embodiment is: as depicted in figs. 1 and 2, soup air communication in the spraying machine medicine-chest 2 is crossed 1 ejection of spraying machine nozzle, trickle to reclaiming in the cup 3 at excessive part soup blowing medicine machine nozzle 1 outer wall of the edge of spraying machine nozzle 1, reclaim the soup that is recovered in the cup 3 and flow in the spraying machine medicine-chest 2, thereby realize excessive soup voluntary recall and utilization again through flow-guiding mouth 3-1, return duct 4.
Claims (3)
1. voluntary recall device that is used for the excessive soup in spraying machine nozzle place, it is characterized in that: described voluntary recall device comprises recovery cup (3) and a return duct (4), reclaiming cup (3) sealing shroud is contained on the spraying machine nozzle (1), and the upper edge of reclaiming cup (3) is lower than the upper edge of spraying machine nozzle (1), the lower end of reclaiming cup (3) sidewall has flow-guiding mouth (3-1), one end of return duct (4) and flow-guiding mouth (3-1) are tightly connected, and the other end of return duct (4) and spraying machine medicine-chest (2) are tightly connected.
