Description

Technical Field

[0001] This utility model relates to the field of spray nozzle technology, specifically a spray nozzle for a spraying machine. Background Technology

[0002] The spray nozzle is the core component of a pesticide spraying system. Its function is to atomize the pesticide solution into droplets of appropriate size and distribute them evenly over the target area. The nozzle controls the atomization effect through special internal structures (such as vortex chambers and fan-shaped orifices), ensuring that the pesticide solution can fully cover the crop leaves (to control pests and diseases) while minimizing drift loss.

[0003] A sprayer nozzle disclosed in patent publication number CN211726219U includes a connector and threads. The devices are connected in position, and then the nozzle is connected to the sprayer. A filter is placed at the right end of the connector, nested inside the connector. The outer wall of the connector is threaded. The connector is screwed onto the sprayer along the threads. The sprayer is filled with pesticide solution, which is first filtered by the filter to remove larger particles, preventing them from clogging the upper or lower water outlet pipes. The upper water outlet pipe is straight, while the left end of the lower water outlet pipe is horizontally inclined upwards. The pesticide solution flows along both pipes and is sprayed from the outlet ends. The sprayed solution is blocked and dispersed by a baffle. Because the baffle is a long, arc-shaped baffle, the solution slides down the inner wall of the baffle, ensuring all the solution lands on the crops.

[0004] During the spraying process of the above-mentioned device, although the filter can filter out larger impurities in the liquid, the filtered particles are prone to clogging the filter holes. Once clogging occurs, the spraying range of the liquid will be reduced, which will greatly reduce the spraying effect. To address the above problems, a spray head for a sprayer is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a spray head for a pesticide sprayer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spray head for a pesticide sprayer includes a housing and a fixed housing slidably disposed within the housing. A rotating rod is rotatably disposed within the fixed housing, and a filter assembly for processing pesticide liquid is disposed on the rotating rod.

[0008] The filter assembly includes filter plates and fixed scrapers. Several sets of filter plates are fixedly connected to a rotating rod, and several sets of fixed scrapers are fixedly connected to the inner wall of a fixed housing. One side of the fixed scraper is slidably engaged with one side of the filter plate, and the outer wall of the filter plate is slidably engaged with the inner wall of the fixed housing. An adjusting component for rotating the rotating rod is provided inside the fixed housing.

[0009] A positioning component for fixing the housing is provided on one side of the outer shell.

[0010] In one alternative embodiment: the adjusting component includes a rotating blade, which is fixedly connected to a rotating rod and located inside a fixed housing; a positioning plate is rotatably connected to one side of the rotating rod and is fixedly connected inside the fixed housing.

[0011] In one alternative: the positioning component includes a locking block and a locking slot, two sets of the locking blocks are respectively fixedly connected to both sides of the fixed shell, and two sets of the locking slots are opened at the bottom of the shell, with the locking block engaging in the locking slot.

[0012] In one alternative: an arc-shaped scraper is fixedly connected to the end of the rotating rod away from the positioning plate, and the outer wall of the arc-shaped scraper slides in fit with the inner wall of the outer shell.

[0013] In one alternative: the inner wall of the outer casing has several sets of water outlet holes on the side near the arc-shaped scraper.

[0014] In one alternative: the inner wall of the housing is provided with a threaded area.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features an outer shell, a fixed shell, a rotating rod, and a filter assembly. The liquid medicine impacts the rotating blades through the three-layer filter plates, causing the rotating blades to drive the rotating rod to rotate. This, in turn, causes the filter plates to rotate within the fixed shell, allowing the fixed scraper to scrape the surface of the filter plates. This prevents impurities from clogging the filter holes on the filter plates, which would otherwise reduce the spraying range and decrease the spraying effect.

[0017] This invention uses a positioning component to allow the fixed shell to slide outward inside the outer shell, thereby disengaging the locking block from the slot and facilitating the cleaning and replacement of the filter plate. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] 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.

[0024] Please see Figures 1-3 In this embodiment, a spray head for a sprayer includes a housing 101 and a fixed housing 102 slidably disposed within the housing 101. A rotating rod 103 is rotatably disposed within the fixed housing 102, and a filter assembly for processing the pesticide solution is disposed on the rotating rod 103.

[0025] The filtration assembly includes filter plates 106 and fixed scrapers 107. Several sets of filter plates 106 are fixedly connected to a rotating rod 103, and several sets of fixed scrapers 107 are fixedly connected to the inner wall of a fixed housing 102. One side of the fixed scraper 107 is slidably engaged with one side of the filter plate 106, and the outer wall of the filter plate 106 is slidably engaged with the inner wall of the fixed housing 102. An adjusting component is provided inside the fixed housing 102 for rotating the rotating rod 103. The adjusting component adjusts the rotating rod 103 to rotate, thereby driving the filter plate 106 to rotate inside the fixed housing 102, so that the fixed scrapers 107 scrape the surface of the filter plate 106, avoiding impurities from clogging the filter holes on the filter plate 106, which would reduce the spraying range of the liquid and decrease the spraying effect.

[0026] A positioning component for fixing the fixed shell 102 is provided on one side of the outer shell 101.

[0027] The adjusting component includes a rotating blade 105, which is fixedly connected to a rotating rod 103. The rotating blade 105 is located inside a fixed housing 102. A positioning plate 108 is rotatably connected to one side of the rotating rod 103. The positioning plate 108 is fixedly connected inside the fixed housing 102. The liquid medicine impacts the rotating blade 105, causing the rotating blade 105 to drive the rotating rod 103 to rotate, which facilitates driving the rotating rod 103 to rotate.

[0028] The positioning component includes a locking block 109 and a locking slot 110. Two sets of locking blocks 109 are fixedly connected to both sides of the fixed shell 102, and two sets of locking slots 110 are opened at the bottom of the outer shell 101. The locking block 109 is engaged in the locking slot 110. The fixed shell 102 slides outward inside the outer shell 101 and drives the locking block 109 to disengage from the locking slot 110, which facilitates the cleaning and replacement of the filter plate 106. At the same time, it can position the fixed shell 102 to prevent the fixed shell 102 from shaking inside the outer shell 101.

[0029] An arc-shaped scraper 104 is fixedly connected to one end of the rotating rod 103 away from the positioning plate 108. The outer wall of the arc-shaped scraper 104 slides in cooperation with the inner wall of the outer shell 101. Several sets of water outlet holes 111 are opened on the side of the inner wall of the outer shell 101 near the arc-shaped scraper 104. By setting several sets of water outlet holes 111, it is convenient for the medicine to be sprayed out. The rotating rod 103 drives the arc-shaped scraper 104 to rotate, which can prevent the water outlet holes 111 from being blocked.

[0030] The inner wall of the outer casing 101 is provided with a threaded area, which facilitates the connection of the outer casing 101 to an existing spraying rod.

[0031] The working principle of this utility model is as follows: In use, firstly, one end of the existing spraying rod is inserted into the outer casing 101 and rotated to connect with the inner wall of the outer casing 101. The spraying equipment delivers the pesticide solution into the outer casing 101. The pesticide solution impacts the rotating blades 105 through the three-layer filter plates 106, causing the rotating blades 105 to drive the rotating rod 103 to rotate, thereby causing the filter plates 106 to rotate within the fixed casing 102. This causes the fixed scraper 107 to scrape the surface of the filter plates 106, preventing impurities from clogging the filter holes on the filter plates 106. In case of blockage, which reduces the spraying range and decreases the spraying effect, the rotating rod 103 simultaneously drives the arc-shaped scraper 104 to scrape the inner wall of the outer casing 101 near the water outlet 111 to prevent the water outlet 111 from becoming blocked. During cleaning, the outer casing 101 can be rotated to remove it from the spraying rod, and the positioning plate 108 can be pulled outward, so that the fixing shell 102 slides outward inside the outer casing 101 and drives the locking block 109 to disengage from the locking groove 110, making it easier to clean and replace the filter plate 106.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
