Description
Technical Field
[0001] This utility model relates to the field of spray nozzle technology, specifically to a pesticide spray nozzle used on grapes. Background Technology
[0002] In the process of grape cultivation, in order to ensure the healthy growth of grapes, it is necessary to spray pesticides on grape plants regularly to prevent and control pests and diseases. At present, hydraulic sprayers are widely used in grape spraying operations, and the matching nozzles are mostly fan-shaped nozzles. However, this traditional spraying method has certain technical limitations: the branches, leaves, and fruits of grapevines are distributed in a variety of layers, with some areas close to the nozzle and others far away. If only fan-shaped nozzles are used, it is difficult to meet both needs at the same time. On the one hand, sufficient water mist impact force is needed to deliver the pesticide to the branches, leaves, and fruits far from the nozzle to ensure that the fruit surface is evenly covered with pesticide. On the other hand, for fruits close to the nozzle, the bloom (which has an important impact on fruit quality) on the fruit surface is easily washed away by the high-pressure spray from the fan-shaped nozzle, resulting in the formation of "glass bead fruit" and affecting the appearance and quality of the grapes. In addition, the spray range and droplet characteristics of a single nozzle are fixed, making it difficult to adapt to the spraying needs of different parts of the grapevine, and it is easy to miss spraying dead spots, which affects the control effect of pesticides. Therefore, there is an urgent need for a spray nozzle design that can take into account the spraying needs at different distances, protect the fruit bloom, and reduce missed spraying. Utility Model Content
[0003] The purpose of this invention is to provide a pesticide spray nozzle for use on grapes, in order to solve the problem mentioned in the background art that a single nozzle is difficult to adapt to the spraying needs of different parts of the grape plant.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pesticide spray nozzle for use on grapes, comprising a spray curved rod and a fan-shaped nozzle. The outer surfaces of both ends of the spray curved rod are fixedly installed with mounting grooves, and the mounting grooves face the same direction. An extension rod is fixedly installed on the outer surface of the spray curved rod, and the extension rod faces the same direction as the mounting grooves. The extension rod is located between the mounting grooves, and a fan-shaped nozzle is rotatably installed above the mounting grooves. A hollow conical nozzle is threaded onto the outer surface of the extension rod.
[0005] Preferably, the hollow cone nozzle is higher than the height of the fan-shaped nozzle.
[0006] Using the above technical solution, the hollow cone nozzle is 6 cm higher than the fan-shaped nozzle. Through the height difference between the hollow cone nozzle and the fan-shaped nozzle, the impact force generated by the liquid sprayed by the fan-shaped nozzle allows the hollow cone nozzle to spray a finer mist that can travel further, thus improving the distance and quality of the mist spraying.
[0007] Preferably, a sealing gasket is inserted into the mounting groove, a spherical head is fixedly installed on the outer surface of the fan-shaped nozzle near the mounting groove, and the outer surface of the spherical head has a groove, and the outer surface of the spherical head fits against the outer surface of the sealing gasket. A threaded clamping mechanism is provided between the fan-shaped nozzle and the mounting groove.
[0008] By employing the above technical solution, the angle of the fan-shaped nozzle can be adjusted through the use of sealing gaskets and spherical heads. Furthermore, the grooves on the outer surface of the spherical head allow water to enter the fan-shaped nozzle even after rotation. This allows the angle of the fan-shaped nozzle to be adjusted freely, better adapting to the spraying needs of different parts of the grapevines. For example, adjusting the angle for inner branches and leaves or outer fruits can further reduce missed spraying areas and allow the pesticide to more accurately cover the target area.
[0009] Preferably, the threaded clamping mechanism includes: a top pressure ring, which is sleeved on the outer surface of the fan-shaped nozzle, and a spiral cap is engaged with the outer surface of the spherical head, with the spiral cap being threadedly connected to the mounting groove, and the outer surface of the top pressure ring being in contact with the outer surfaces of the spherical head and the spiral cap respectively.
[0010] By adopting the above technical solution, the tightening of the screw cap and the cooperation of the top pressure ring allow the top pressure ring to move and press the spherical head when the screw cap is tightened with the mounting groove, thereby fixing the angle and position of the fan-shaped nozzle and preventing the fan-shaped nozzle from moving arbitrarily due to the pressure of the sprayed medicine during use.
[0011] Preferably, a nut is rotatably installed at one end of the spray rod, and a filter shell is threaded onto the outer surface of the nut. The other end of the filter shell is threadedly connected to the spray rod. The filter shell is a circular shell made of transparent material. A third sealing ring is provided between the nut and the filter shell, and the two ends of the third sealing ring are respectively engaged with the outer surfaces of the spray rod and the filter shell. A second sealing ring is provided between the filter shell and the spray rod, and the outer surface of the second sealing ring is tightly fitted to the outer surfaces of the filter shell and the spray rod.
[0012] By adopting the above technical solution, the connection between the spray boom, filter shell and spray boom is sealed by the use of the third sealing ring and the second sealing ring, which reduces the chance of pesticide leakage during spraying. The condition of the internal filter element can be observed through the filter shell, and it is easy to know when to replace the filter element and replace the filter element without affecting the spraying effect of the spray head.
[0013] Preferably, a first sealing ring is inserted into the interior of the filter housing, and the outer surface of the first sealing ring is in contact with the outer surface of the filter housing. A retaining ring is inserted into the interior of the filter housing, and the outer surface of the retaining ring is in contact with the outer surface of the first sealing ring. A filter element is inserted into the outer surface of the retaining ring, and the outer surface of the filter element is not in contact with the outer surface of the filter housing.
[0014] By employing the above technical solution, the use of the first sealing ring allows the filter element, retaining ring, and extrusion cone to be inserted into the filter housing. Through the engagement of the extrusion cone with the spray bar and the mutual tightening of the filter housing and the spray bar, the retaining ring and the first sealing ring can fit tightly together. This allows the filter element, retaining ring, and extrusion cone to be mutually squeezed and locked by simply tightening the filter housing and the spray bar, improving the sealing performance between the filter element, retaining ring, and extrusion cone while reducing the probability of unfiltered liquid being discharged from the spray bar. Furthermore, the filter element can be easily disassembled and replaced when its filtration effect is poor.
[0015] Preferably, a compression cone is inserted and installed on the outer surface of the end of the filter element away from the retaining ring, and the compression cone is made of conical partitions spliced together. The outer surface of the compression cone is not in contact with the outer surface of the filter shell. Water permeable holes are evenly opened on the outer surface of the end of the filter shell away from the spray bar. The outer surface of the compression cone is inserted into the outer surface of the spray bar.
[0016] By adopting the above technical solution, the liquid medicine entering through the spray bar can flow along the extrusion cone and into the interior of the filter shell. After being filtered by the filter element, the filter area of the liquid medicine can be expanded by the arrangement of the filter element and the filter shell, thereby improving the efficiency of filtering impurities in the liquid medicine. The filtered liquid medicine can also flow through the water permeable holes into the spray bend bar and be sprayed outwards. This ensures that the liquid medicine is not mixed with impurities, which would affect the quality of the liquid medicine sprayed by the hollow cone nozzle and the fan nozzle, thus improving the spraying effect.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the pesticide spray nozzle used on the grapes: 1. Through the arc design of the spray boom, and the use of hollow cone nozzles and fan-shaped nozzles installed on the outer surface of the spray boom, the pesticide sprayed by the fan-shaped nozzles can carry the pesticide mist sprayed by the hollow cone nozzles, so that the grape spraying operation can have both the impact force of water mist and the performance of fine droplets. Secondly, through the setting of the extension rod, a height difference can be formed between the hollow cone nozzles and the fan-shaped nozzles, so that the impact force of the pesticide sprayed by the fan-shaped nozzles can carry the finer pesticide mist sprayed by the hollow cone nozzles to travel further, thereby improving the spraying distance and spraying quality, and ensuring the spraying needs of different parts of the grape vines. 2. By using the sealing gasket and the ball head, and tightening the screw cap and the mounting groove, the top pressure ring can move together with the tightening of the screw cap. This allows the top pressure ring to press the ball head and form a clamping state with the sealing gasket, so that the spray angle of the fan-shaped nozzle can be adjusted to better adapt to the spraying needs of different parts of the grape, further reduce the dead spots of missed spraying, and allow the liquid to cover the target area more accurately. 3. By assembling the filter element, retaining ring, and extrusion cone, and inserting them into the filter housing, the retaining ring can fit against the outer surface of the first sealing ring. Then, by tightening the filter housing and the spray bar, the spray bar can move with the tightening and push the extrusion cone, allowing the filter element, retaining ring, and extrusion cone to squeeze against each other and ensure a tight connection. Subsequently, the medicine will enter the interior of the filter housing through the spray bar and be filtered by the filter element to remove impurities in the medicine. After filtration, the medicine can flow into the interior of the spray bar through the water permeable holes, so that large particles of impurities in the medicine can be filtered out and will not enter the interior of the hollow cone nozzle and fan nozzle to cause blockage, thus ensuring the spray effect of the hollow cone nozzle and fan nozzle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-6 This utility model provides a technical solution: a pesticide spray nozzle for use on grapes, including a spray curved rod 1 and a fan-shaped nozzle 7. The outer surfaces of both ends of the spray curved rod 1 are fixedly installed with mounting grooves 4, and the mounting grooves 4 are oriented in the same direction. An extension rod 2 is fixedly installed on the outer surface of the spray curved rod 1, and the extension rod 2 is oriented in the same direction as the mounting grooves 4. The extension rod 2 is located between the mounting grooves 4, and the fan-shaped nozzle 7 is rotatably installed above the mounting grooves 4. A hollow conical nozzle 3 is threadedly installed on the outer surface of the extension rod 2, and the hollow conical nozzle 3 is higher than the height of the fan-shaped nozzle 7.
[0022] Firstly, during use, the liquid pesticide is fed into the interior of the spray boom 1 through the spray bar 15 and sprayed outward from the hollow cone nozzle 3 and the fan-shaped nozzle 7. At the same time, the extension of the extension rod 2 can create a distance between the hollow cone nozzle 3 and the fan-shaped nozzle 7, allowing the fan-shaped nozzle 7 to spray finer particles from the hollow cone nozzle 3 with a stronger impact force. This allows the pesticide mist to be carried and blown to the grape branches and leaves at a greater distance, so that the surface of the grape branches, leaves and fruits at different distances can be evenly covered with the pesticide, and the dead corners of the spray are reduced to protect the fruit powder on the surface of the fruit, thereby improving the spraying distance and spraying quality of the pesticide mist from the spray nozzle.
[0023] A sealing gasket 5 is inserted into the mounting groove 4. A spherical head 8 is fixedly installed on the outer surface of one end of the fan-shaped nozzle 7 near the mounting groove 4. The outer surface of the spherical head 8 has a groove and is in contact with the outer surface of the sealing gasket 5. A threaded clamping mechanism is provided between the fan-shaped nozzle 7 and the mounting groove 4. The threaded clamping mechanism includes a top pressure ring 6, which is sleeved on the outer surface of the fan-shaped nozzle 7. A spiral cap 9 is fitted onto the outer surface of the spherical head 8 and is threadedly connected to the mounting groove 4. The outer surface of the top pressure ring 6 is in contact with the outer surfaces of the spherical head 8 and the spiral cap 9, respectively.
[0024] Secondly, when dealing with different grape varieties, the fan-shaped nozzle 7 can be rotated, allowing the spherical head 8 to rotate between the sealing gasket 5 and the top pressure ring 6. By tightening the screw cap 9 and the mounting groove 4, the sealing gasket 5 and the top pressure ring 6 can press against each other and press against the spherical head 8. This allows the angle and position of the fan-shaped nozzle 7 to be fixed and sealed. This can better adapt to the spraying needs of different parts of the grape according to the growth pattern of the grape branches and leaves, the different locations of branches, leaves and fruits, further reducing blind spots and allowing the liquid to cover the target area more accurately, greatly improving the practicality of the spray nozzle.
[0025] A nut 17 is rotatably mounted on one end of the spray boom 1, and a filter shell 10 is threaded onto the outer surface of the nut 17. The other end of the filter shell 10 is threadedly connected to the spray boom 15. The filter shell 10 is a circular shell made of transparent material. A third sealing ring 18 is provided between the nut 17 and the filter shell 10, and the two ends of the third sealing ring 18 are respectively engaged with the outer surfaces of the spray boom 1 and the filter shell 10. A second sealing ring 16 is provided between the filter shell 10 and the spray boom 15, and the outer surface of the second sealing ring 16 is tightly fitted to the outer surfaces of the filter shell 10 and the spray boom 15. A first sealing ring 11 is inserted into the inside of the filter shell 10, and the outer surface of the first sealing ring 11 is... The surface is in contact with the outer surface of the filter housing 10. A retaining ring 13 is inserted into the inside of the filter housing 10, and the outer surface of the retaining ring 13 is inserted into the outer surface of the first sealing ring 11. A filter element 12 is inserted into the outer surface of the retaining ring 13, and the outer surface of the filter element 12 is not in contact with the outer surface of the filter housing 10. A compression cone 14 is inserted into the outer surface of the end of the filter element 12 away from the retaining ring 13. The compression cone 14 is made of conical partitions spliced together, and the outer surface of the compression cone 14 is not in contact with the outer surface of the filter housing 10. Water permeable holes 19 are evenly opened on the outer surface of the end of the filter housing 10 away from the spray bar 15. The outer surface of the compression cone 14 is inserted into the outer surface of the spray bar 15.
[0026] Furthermore, by using the nut 17 and the third sealing ring 18, the spray rod 1 and the filter shell 10 can be connected and fixed. Then, the filter element 12, the retaining ring 13, and the extrusion cone 14 can be assembled and snapped together. Subsequently, the filter element 12, the retaining ring 13, and the extrusion cone 14 can be placed into the interior of the filter shell 10. Through the contact and engagement of the first sealing ring 11 and the retaining ring 13, and the tightening of the filter shell 10 and the spray rod 15, and the use of the second sealing ring 16, the spray rod 15 can move as it is tightened, pushing the extrusion cone 14. This allows the filter element 12, the retaining ring 13, and the extrusion cone 14 to squeeze each other and form a seal, so that the medicine passing through the spray rod 15 can be filtered through the filter element 12 and discharged from the water permeable hole 19. This improves the filtration efficiency of the filter element 12 and reduces the probability of clogging caused by impurities in the medicine entering the hollow cone nozzle 3 and the fan-shaped nozzle 7, thus ensuring the spray quality of the hollow cone nozzle 3 and the fan-shaped nozzle 7.
[0027] Working principle: The medicine enters the interior of the filter housing 10 through the spray bar 15 and flows along the inner wall of the filter housing 10, allowing the medicine to pass through the filter element 12 and be discharged through the water permeable hole 19. This allows the medicine to pass through the filter element 12 to remove impurities and enter the interior of the spray bar 1. This prevents the medicine from being blocked and causing poor spraying effect when sprayed from the hollow conical nozzle 3 and the fan-shaped nozzle 7. Furthermore, the angle and position of the fan-shaped nozzle 7 can be adjusted through the coordinated use of the sealing gasket 5, the top pressure ring 6, the ball head 8, and the spiral cap 9. The extension rod 2 creates a distance difference between the hollow cone nozzle 3 and the fan-shaped nozzle 7, allowing the fan-shaped nozzle 7 to spray a finer mist from the hollow cone nozzle 3 with a stronger impact force, reaching further grape branches and leaves. This ensures that the pesticide solution is evenly applied to the surface of the grape branches, leaves, and fruits at different distances, greatly reducing missed areas at the four corners and protecting the bloom on the fruit surface. This prevents the bloom from being washed away by the high spray pressure, thus avoiding the formation of glass beads on the fruit and ensuring the quality of the grapes after the pesticide is applied.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
