Description

Technical Field

[0001] This application relates to the technical field of agricultural irrigation, and more specifically, to a spraying device for agricultural irrigation. Background Art

[0002] Agricultural irrigation mainly refers to the irrigation operations carried out in agricultural cultivation areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. Crops need to be irrigated with water regularly during the growth process to effectively help the crops grow better. With the continuous improvement of agricultural equipment, manual labor has basically been replaced by mechanization, thus greatly reducing the labor intensity of farmers. However, although there are a variety of existing spraying devices for agricultural irrigation, most of the spraying devices can only be used for spraying crops, with low practicability. Secondly, since most spraying devices draw water from canals or rivers around the farmland, the water contains more debris and impurities. Although the existing spraying devices have a filtering structure, the filtering structure of the spraying device is too simple and the filtering effect is poor, resulting in the blockage of pipelines or the nozzles of the spraying device after long-term use, affecting the spraying effect.

[0003] The prior art document with the publication number of CN 116649184 A provides a spraying device for agricultural irrigation. One end of the pumping hose of the device is placed in a canal or river, and the water in the canal or river is pumped by the first pump body. Under the action of the first pump body, the pumped water is filtered through a filter box, and the filtered water enters the spraying pipeline and the spray water pipe, and is sprayed out through the uniformly distributed nozzles installed on the surface of the spray water pipe to spray the crops that need to be irrigated, completing the spraying irrigation of the crops.

[0004] Although the above prior art solution can achieve relevant beneficial effects through the structure of the prior art, there are still the following defects: during the irrigation process of the device, different crops have different water requirements and irrigation methods. For example, shallow-rooted crops (such as vegetables, nurseries, flowers) may require a smaller amount of sprayed water and a higher degree of atomization to promote root absorption and reduce surface runoff; while deep-rooted crops (such as fruit trees, corn) may require a larger amount of sprayed water and a longer spraying range to ensure that the roots receive sufficient water supply. However, the number of nozzles of the device cannot be adjusted, and thus the number of nozzles discharging water cannot be adjusted when irrigating different crops.

[0005] In view of this, we propose a spraying device for agricultural irrigation. Utility Model Content

The first through hole corresponds to each nozzle, and all the nozzles can discharge water at this time. During adjustment, by rotating the inner sleeve and making the second through hole correspond to the nozzle, at this time, the first through hole and the third through hole are blocked by the inner wall of the spray water pipe. At this time, a plurality of nozzles are blocked at an interval of one, and the nozzles separated by one nozzle discharge water. Rotate the inner sleeve again and make the third through hole correspond to the nozzle. At this time, the first through hole and the second through hole are blocked by the inner wall of the spray water pipe. At this time, a plurality of nozzles are blocked at an interval of two, and then the nozzles after being separated by two nozzles discharge water. Finally, fix the inner sleeve on the spray water pipe, and finally realize the quick adjustment of the water output quantity of the nozzle according to the water demand of different crops.

[0011] As an optional solution of the technical solution of this application document, a filter cover is fixedly installed between the two inner sleeves, and the filter cover is placed at the spraying pipeline.

[0014] By adopting the above technical solution, the inner sleeve is rotated inside the water spray pipe by turning the screw rod, and then the butterfly nut is rotated to be pressed and fixed on the water spray pipe, so that the inner sleeve can be fixed on the water spray pipe.

[0015] As an alternative solution of the technical solution of this application document, three identification stickers are annularly distributed at one end of the inner sleeve close to the screw rod, a viewing window corresponding to the identification stickers is opened at the end of the water spray pipe, and the viewing window is parallel to the spray head.

Detailed implementation manners

[0029] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0030] A spraying device for agricultural irrigation includes a spraying pipeline 1, a water spraying pipe 2 vertically and penetratingly connected to the spraying pipeline 1, and a plurality of nozzles 3 evenly distributed on the water spraying pipe 2. Two groups of inner sleeves 4 are rotatably arranged inside the water spraying pipe 2. One end of the two groups of inner sleeves 4 close to the spraying pipeline 1 is an open structure. An opening communicating with the spraying pipeline 1 is reserved at the adjacent ends of the two groups of inner sleeves 4. The inner sleeve 4 and the water spraying pipe 2 are detachable. A plurality of first through holes 41, a plurality of second through holes 42, and a plurality of third through holes 43 corresponding to the nozzles 3 are axially distributed on the inner sleeve 4. The first through holes 41, the second through holes 42, and the third through holes 43 are annularly distributed. The number of the first through holes 41 is the same as the number of the nozzles 3. A plurality of the second through holes 42 are arranged at an interval of one nozzle 3, and a plurality of the third through holes 43 are arranged at an interval of two nozzles 3.

[0031] Refer to Figures 1-6By rotating the inner sleeve 4, water flows through the spray pipe 1 and enters the inner sleeve 4. When the first through hole 41 corresponds to the nozzle 3, the second through hole 42 and the third through hole 43 are blocked by the inner wall of the spray pipe 2. The first through hole 41 corresponds to each nozzle 3. At this time, all the nozzles 3 can discharge water. When adjusting, by rotating the inner sleeve 4 and making the second through hole 42 correspond to the nozzle 3, the first through hole 41 and the third through hole 43 are blocked by the inner wall of the spray pipe 2. The nozzles 3 are blocked one at a time, and the nozzles 3 separated by one nozzle 3 discharge water. When the inner sleeve 4 is rotated again and the third through hole 43 corresponds to the nozzle 3, the first through hole 41 and the second through hole 42 are blocked by the inner wall of the water spray pipe 2. At this time, the multiple nozzles 3 are blocked two at a time, and then the nozzles 3 separated by two nozzles 3 discharge water. Finally, the inner sleeve 4 is fixed on the water spray pipe 2, thereby realizing the rapid adjustment of the water output amount of the nozzle 3 according to the water demand of different crops.

[0032] A filter cover 5 is fixedly installed between the two inner sleeves 4 , and the filter cover 5 is placed on the spraying pipeline 1 .

[0033] Reference Figure 3 and Figure 5 The two inner sleeves 4 are fixedly connected by the filter cover 5, which can achieve the purpose of rotating the two inner sleeves 4 at the same time and ensure normal water flow.

[0034] A screw rod 44 is coaxially fixed to one end of the inner sleeve 4 away from the filter cover 5 . The screw rod 44 passes through the water spray pipe 2 . A butterfly nut 45 is threadedly connected to the screw rod 44 .

[0035] Reference Figure 2 , rotate the screw 44 to make the inner sleeve 4 rotate inside the water spray pipe 2, and then rotate the butterfly nut 45 to squeeze and fix it on the water spray pipe 2, so that the inner sleeve 4 can be fixed on the water spray pipe 2.

[0036] One end of the inner sleeve 4 close to the screw 44 is provided with three identification stickers 46 distributed in a ring shape, and the end of the water spray pipe 2 is provided with a viewing window 21 corresponding to the identification sticker 46 , and the viewing window 21 is parallel to the spray head 3 .

[0037] Reference Figure 2 and Figure 6 The three identification stickers 46 correspond to the three groups of through holes respectively, so that the operator can easily determine the positions of the through holes when rotating the inner sleeve 4. When the identification stickers 46 coincide with the viewing window 21, the through holes correspond to and are connected with the nozzle 3.

[0038] The three identification stickers 46 are respectively red, yellow and blue. The red identification sticker 46 corresponds to the first through hole 41 , the yellow identification sticker 46 corresponds to the second through hole 42 , and the blue identification sticker 46 corresponds to the third through hole 43 .

[0039] Through identification stickers 46 of three different colors, namely red, yellow, and blue, the first through-hole 41, the second through-hole 42, and the third through-hole 43 can be easily identified, facilitating the operation and observation of the number of through-holes of the corresponding nozzle 3.

[0040] Working principle: Loosen the wing nut 45, and then use a vise to clamp the screw rod 44 to assist the rotation of the screw rod 44, causing the inner sleeve 4 to rotate. When the second through-hole 42 corresponds to the nozzle 3, at this time, the first through-hole 41 and the third through-hole 43 are blocked by the inner wall of the water spray pipe 2. At this time, every other one of the multiple nozzles 3 is blocked, and the nozzles 3 separated by one nozzle 3 discharge water. Rotate the inner sleeve 4 again, and when the third through-hole 43 corresponds to the nozzle 3, at this time, the first through-hole 41 and the second through-hole 42 are blocked by the inner wall of the water spray pipe 2. At this time, every two of the multiple nozzles 3 are blocked, and then the nozzles 3 after being separated by two nozzles 3 discharge water. Finally, fix the inner sleeve 4 on the water spray pipe 2, and finally, the rapid adjustment of the water discharge quantity of the nozzle 3 according to the water demand of different crops is realized. Finally, rotate the wing nut 45 clockwise and press it on the water spray pipe 2 to complete the fixation.
