Description

Technical Field

[0001] The utility model relates to the technical field of spray nozzles, in particular to a novel spray nozzle with an elbow. Background Art

[0002] In the entire cycle of grape planting, spraying pesticides is an indispensable link. By spraying pesticides on grape plants, the goals of protecting flowers and fruits, preventing diseases and pests can be achieved, so as to ensure the grape yield and quality of the season.

[0003] The nozzles commonly used for vineyard spraying on the market are mostly similar in structure. They are generally straight nozzles, which are directly installed on the spray pipe of the sprayer. The spray direction is single, and can only be used to spray the leaves of grapes, which has little impact on the pests under the leaves. Spraying on both sides requires two operations, which has low spraying efficiency and increases the consumption of pesticides. It does not have the function of synchronous spraying up and down. Secondly, grape spraying generally requires the liquid to be atomized and sprayed. The holes of the spray nozzle itself are small. Once there are foreign particles in the water agent during the spraying process, it is easy to cause the fog outlet of the nozzle to be blocked, affecting the normal spraying efficiency. It does not have the function of filtering the water agent to prevent clogging. In addition, the nozzles currently on the market are either straight nozzles or curved nozzles, with relatively fixed angles, and cannot be adjusted according to the actual specifications of the plants to be sprayed, and do not have the function of facilitating the adjustment of the nozzle angle.

[0004] Now, a new type of nozzle with an elbow is proposed to solve the above problems. Utility Model Content

[0016] By providing a water distribution pipe, a first elbow pipe, a first nozzle mounting seat, a lower nozzle, a first atomizing spray eye, a second elbow pipe, a second nozzle mounting seat, an upper nozzle and a second atomizing spray eye, when in use, the water pipe interface and the medicine outlet pipe of the sprayer are connected, the sprayer pumps the liquid medicine into the water distribution pipe through the water pipe interface, and the liquid medicine enters the water distribution pipe through the filter tube and the water outlet pipe, and the liquid medicine passes through the first elbow pipe and the second elbow pipe and enters the lower nozzle and the upper nozzle respectively, and sprays fine and dense liquid medicine through the first atomizing spray eye and the second atomizing spray eye. The medicine mist, the inner diameter of the first elbow pipe is large, the specification of the lower nozzle installed on the first nozzle mounting seat is also large, the amount of liquid sprayed by the five groups of first atomizing spray eyes is large and the degree of atomization is high, so the back of the leaves can be sprayed with medicine, the inner diameter of the second elbow pipe is small, the specification of the upper nozzle installed on the second nozzle mounting seat is also small, the amount of liquid sprayed by the three groups of second atomizing spray eyes is small and the degree of atomization is also low, so the leaves can be sprayed with medicine, and the grape leaves and the back of the leaves can be sprayed with liquid at one time, realizing the function of synchronous spraying up and down;

The stainless steel filter screen in the filter barrel can intercept floating objects and particulate matter in the water body to prevent them from clogging the atomizing spray eye. The positioning ring can limit the position of the stainless steel filter screen. Subsequently, the internal thread sealing cap can be unscrewed along the connecting thread port, and the stainless steel filter screen can be taken out for cleaning, thereby realizing the function of filtering water agent to prevent clogging;

The reserved groove 24 reserves space for the up and down swinging of the second connecting tube 20, and the connecting hose 25 can transport liquid medicine while ensuring the angle adjustment capability.

[0033] Working principle: When the utility model is in use, first, the water pipe interface 17 is connected to the medicine outlet pipe of the sprayer, and the sprayer pumps the liquid medicine along the water pipe interface 17, enters the water distribution pipe 2 through the filter tube 11 and the water outlet pipe 1, and the liquid medicine passes through the first elbow pipe 3 and the second elbow pipe 7 respectively. Enter the lower nozzle 5 and the upper nozzle 9, and spray fine medicine mist through the first atomizing spray eye 6 and the second atomizing spray eye 10. The inner diameter of the first elbow pipe 3 is large, and the specification of the lower nozzle 5 installed on the first nozzle mounting seat 4 is also large. The amount of liquid medicine sprayed by the five groups of the first atomizing spray eyes 6 is large and the degree of atomization is high, so the back of the leaves can be sprayed with medicine.

Before entering the water outlet pipe 1, it must first pass through the filter tube 11. The stainless steel filter 14 in the filter tube 11 can intercept floating objects and particulate matter in the water body to prevent them from clogging the atomizing spray eye. The positioning ring 15 can limit the position of the stainless steel filter 14. Subsequently, the internal thread sealing cap 12 can be unscrewed along the connecting threaded port 13 to remove the stainless steel filter 14 for cleaning. The water pipe interface 17 is connected to the medicine outlet pipe of the sprayer, and the external hexagonal pipe sleeve 16 is connected to the internal thread sealing cover 12 on one side of the filter tube 11. The installation angle of the nozzle can be controlled according to the actual shape of the grape plant. First, loosen the adjusting nut 22, and the distance between the damping gasket 21 and the front end of the second connecting pipe 20 increases and the friction force is weakened. At this time, the second connecting pipe 20 can swing up and down with the external threaded connecting rods 19 at both ends of the first connecting pipe 18 as fulcrums to adjust the angle. After adjusting to the appropriate angle, tighten the adjusting nut 22 again. The adjusting nut 22 pushes the damping gasket 21 to press against the second connecting pipe 20. The relative position between the first connecting pipe 18 and the second connecting pipe 20 is fixed, and the angle is also fixed. The reserved groove 24 reserves space for the up and down swinging of the second connecting pipe 20, and the connecting hose 25 can transport the medicine solution while ensuring the angle adjustment capability.
