Description

Technical Field

[0001] The utility model relates to the technical field of rice seedling cultivation, and specifically discloses a rice drought-resistant seedling cultivation spraying device. Background Art

[0002] Rice dryland seedling cultivation technology is a technology for cultivating rice seedlings under waterless conditions. Through scientific soil management, temperature control and nutrient supply, it enables rice seedlings to thrive in arid environments. This technology breaks through the limitations of traditional rice seedling cultivation, has wide applicability and significant water-saving effects.

[0003] The amount of water required in the process of raising rice seedlings in arid conditions is large, and the existing water spray system not only has a high layout cost, but is also difficult to recycle, which easily causes the water spray system to be damaged during the subsequent transplanting of seedlings. At present, the industry also uses a single micro-spray belt connected to an external water pump to spray the seedlings, but due to the fixed layout of the pipeline, it cannot be adjusted according to the dry land environment, resulting in poor applicability. In addition, when the micro-spray belt is in a state of stopping spraying, the disappearance of the internal water pressure will cause the micro-spray belt to flatten. At this time, the soil sprayed in the soil is easy to flow back and cover the upper surface of the micro-spray belt, causing the spray holes on the micro-spray belt to be blocked, and the seedlings cannot be sprayed normally subsequently. Based on this, the present application proposes a rice seedling spray device that can effectively solve the above-mentioned technical problems. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 5 , and describes the application in detail with reference to embodiments. Example 1

[0024] Embodiment 1 discloses a rice seedling spraying device, Figure 1 The main body of the device includes a water pump 1, a water distribution belt 2, a four-way pipe 3 and a micro-spray belt 4. A plurality of four-way pipes 3 are arranged in a row in the same transverse furrow of the nursery field, and each four-way pipe 3 is aligned with each vertical furrow of the nursery field. Then, two adjacent four-way pipes 3 are connected by the water distribution belt 2, and the outermost four-way pipe 3 is connected to the water pump 1 by the water distribution belt 2.

[0025] A control valve 301 is provided at both vertical connection ends of the four-way pipe 3, and a micro-spray belt 4 is connected to the outer end of each control valve 301, so that the micro-spray belt 4 is arranged along the vertical furrow direction of the nursery field. The control valve 301 can not only control the flow rate of the corresponding micro-spray belt 4, but also directly cut off the spraying effect of the corresponding micro-spray belt 4. At the same time, multiple groups of spray holes 401 are evenly spaced along the upper surface of each micro-spray belt 4 in the length direction, and each group of spray holes 401 is designed to be five holes and inclined on the upper surface of the micro-spray belt 4, so that the water sprayed from the same group of spray holes 401 during the spraying process can take into account the seedlings on both sides. In addition, the aperture of the spray hole 401 is set between 0.8±0.2mm, on the one hand, the water pressure inside the micro-spray belt 4 is within an appropriate range, and the water flow sprayed from the spray hole 401 can be sprayed in strips, and on the other hand, it can avoid soil adhesion to the micro-spray belt 4 as much as possible to cause the spray hole 401 to be blocked. Example 2

[0026] Example 2 discloses a rice drought seedling raising spray device that is further optimized and improved based on the technical solution in Example 1. The similarities between the device and Example 1 are not described again.

[0027] The rice seedling spraying device of the second embodiment also includes a telescopic hanger 5 for hanging the micro-spraying belt 4. Figure 2 and attached Figure 3 The telescopic bracket 5 includes a multi-stage telescopic sleeve 501, both ends of the multi-stage telescopic sleeve 501 are fixedly connected with end seats 502, and then both ends of the lower surface of the end seat 502 are connected with vertical downward foot nails 503.

[0028] In addition, a plurality of hooks 504 are sleeved on the multi-stage telescopic sleeve 501, and the inclined upper end of each hook 504 is opened, so that the micro-spray belt 4 can be quickly hung between the plurality of hooks 504 or can be quickly removed from the hook 504 when recycled.

[0029] In this embodiment 2, the telescopic bracket 5 can adjust the length of the multi-stage telescopic sleeve 501 according to the length of the vertical ridge of the nursery field when in use; if the maximum length of the multi-stage telescopic sleeve 501 is also less than the length of the vertical ridge of the nursery field, multiple telescopic brackets 5 can be used to increase their applicable length by connecting end to end. The foot nails 503 on the end seat 502 are inserted into the ground of the nursery field to fix it, and then one end of the micro-spraying belt 4 is sealed and connected to the outer end of the control valve 301 on the four-way pipe 3, and then the micro-spraying belt 4 is unfolded along the vertical ridge of the nursery field and hung on multiple hooks 504. In addition, in order to prevent the hook 504 from affecting the water flow route sprayed from the micro-spraying belt 4, the hook 504 is set between two adjacent groups of spray holes 401 as much as possible, and the spray holes 401 are set upward.

[0030] In this embodiment 2, the micro-spray belt 4 is suspended by the telescopic bracket 5, which not only makes the irrigation range of the water sprayed from the micro-spray belt 4 larger, but also prevents the soil in the seedling field from flowing back into the ridge after the spraying is stopped and covering the upper surface of the micro-spray belt 4, thereby preventing the spray hole 401 from being blocked. Example 3

Example 4

[0033] Example 4 discloses a rice drought seedling raising spray device that is further improved and designed based on the technical solution in Example 2, and the similarities between it and Example 2 are not described again.

[0034] This embodiment 4 directly improves the connection method between the foot nail 503 and the end seat 502. For specific solutions, please refer to the attached Figure 5 A vertically downward threaded barrel 507 is welded on the lower surface of the end seat 502, and then a threaded groove 506 matching the threaded barrel 507 is opened on the upper half of the foot nail 503, or a screw matching the threaded barrel 507 is directly welded on the upper end of the foot nail 503, so that the distance between the bottom of the foot nail 503 and the end seat 502 can be adjusted by rotating the foot nail 503, thereby adjusting the height of the micro-spray belt 4 suspended on the hook 504, so that the spraying range of the micro-spray belt 4 can be flexibly adjusted to ensure full coverage of the spray.
