[0002] At present, with the continuous progress and development of science and technology, mechanization and intelligentization are gradually popularized in various industries. In the field of agricultural planting, there are corresponding many devices. In the field of agricultural planting, there are many classifications. Greenhouse planting is one of them. In the process of planting crops in the greenhouse, especially in the development of intelligentization at present, relatively intelligent planting is realized. The device for fertilizing and irrigating crops is included.

[0003] The relatively common intelligent fertilizing and irrigating technology is disclosed in the prior art (CN 112293023 A), which adopts a movable truss scheme to fertilize and irrigate the planting area. That is, the storage tank structure and the spray head structure can move along the planting path, thereby realizing rapid fertilization and irrigation. In the field of agricultural planting at present, the relatively common intelligent fertilizing and irrigating technology scheme is as disclosed above. Although there may be some differences, they are basically the same. However, the above-mentioned fertilizing and irrigating technology scheme has some defects and problems in the process of trial observation, for example: When fertilizing and irrigating, spraying is mostly performed above crops. Fertilizer and water first contact the leaves of the plant, then drip along the leaves to the ground, and finally are absorbed by the root. In this process, since the growth of the leaves of the plant is random, the fertilizer and water cannot be well dropped to the root position when dripping. Most of the fertilizer and water are located around the root, the precision is not enough, and the fertilizer and water are easily wasted. Not only resources are wasted, but also the cost of planting is increased.

[0004] Therefore, we propose an automatic fertilizing device for intelligent agriculture to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Reference Figures 1-4 The present application provides a technical solution of an automatic fertilization device for smart agriculture: Embodiment 1: The fertilization device mainly comprises a truss 1, which can refer to the prior art scheme and mainly comprises a transverse part and a longitudinal part. The longitudinal part is suspendedly installed on the greenhouse frame structure through a suspension structure, and the transverse part is installed on the longitudinal part. A storage tank 2 is installed and fixed at the middle part of the top of the truss 1 through a fastener structure, and a fertilization mechanism is arranged on both sides of the middle region of the truss 1.

[0022] The fertilization mechanism mainly comprises a vertical pipe 3, a bottom column structure 4 is installed in a penetrating threaded manner at the bottom of the vertical pipe 3, a rotating blade 5 is installed on the outer circle of the bottom column structure 4 and at the outer side part of the vertical pipe 3 through a bearing structure, a guide vane 6 is arranged at the top position of the rotating blade 5, and a spray hole structure 7 is formed at the bottom position of both sides of the outer circle of the vertical pipe 3.

[0023] Among them, a threaded column 8 is arranged at the top of the vertical pipe 3, a strip-shaped slot 9 is formed on the opposite side of the truss 1, a limiting bolt 10 is clamped in the inner cavity of the strip-shaped slot 9, a movable table 11 is installed and fixed at the opposite end of the limiting bolt 10, and a threaded hole structure matched with the threaded column 8 is arranged at the bottom of the movable table 11. Through the design of the movable table 11 with adjustable position, the position of the fertilization mechanism can be adjusted according to the real-time crop planting spacing. At the same time, the whole fertilization mechanism is connected and installed by the detachable movable table 11, which is convenient for the later operation and maintenance work, and the length of the vertical pipe 3 can also be selected appropriately, so that the rotating blade 5 can be kept near the crop rootstock position.

[0024] Among them, a butt joint short pipe 12 is arranged at the top position of the side of the vertical pipe 3, and the butt joint short pipe 12 is connected and installed with the discharge port of the storage tank 2 through a hose structure 13. The storage tank 2 is an open-top box structure, a water pump device is arranged in the inner cavity of the storage tank 2, and the water outlet port of the water pump device is connected with the discharge port of the storage tank 2. In actual use, the mixed fertilizer can be easily filled into the storage tank 2, and the fertilizer solution is delivered into the inner cavity of the vertical pipe 3 through the water pump device and the hose structure 13. In this delivery process, the fertilizer solution in the vertical pipe 3 and the hose structure 13 is pressurized.

[0025] Among them, a plugging structure 14 is threadedly installed at the bottom of the vertical pipe 3, a conical body structure 15 is arranged at the top of the plugging structure 14, and the bottom of the conical body structure 15 is at the same horizontal plane as the inner opening lower edge of the lowest position spray hole structure 7. The fertilizer solution delivered by extrusion can flow along the inclined surface of the conical body structure 15 to the spray hole structure 7, and then be sprayed out from the spray hole structure 7. The plugging structure 14 is connected and installed with the vertical pipe 3 in a threaded manner, mainly to facilitate the later cleaning and dredging of the vertical pipe 3, which can be directly screwed off.

[0026] Specifically, the nozzle structure 7 is a downward-sloping arc-shaped nozzle structure, with its outer opening facing the rotating blade 5, which is designed to be tilted. The downward-sloping arc-shaped nozzle structure 7 allows the fertilizer solution to be sprayed directly onto the upper surface of the rotating blade 5 in a water jet manner. After being blocked and redirected by the guide plate 6, the fertilizer solution is delivered to the root zone of the plant, achieving precise fertilization, saving energy, and reducing planting costs to some extent.

[0027] In this embodiment, when using this device for fertilization and irrigation, firstly, based on the spacing of the planting area, the positions of the two fertilization mechanisms are adjusted by adjusting the movable platform 11, so that the fertilization mechanisms are positioned as close as possible to the edge of the planting area. Then, the truss is adjusted to a suitable height using a hydraulic drive device, with the storage tank 2 positioned directly above the plant. After that, the water pump is started to carry out the fertilization and irrigation work. The fertilizer mixture is sprayed out from the nozzle structure 7, directly impacting the rotating blades 5. The rotating blades 5 rotate due to the impact force, and the sprayed fertilizer mixture... By being blocked by the guide vane 6, the fertilizer mixture will flow in a different direction along its side, and finally be thrown to the root and stem position of the plant as the rotating blade 5 rotates. The key to throwing the fertilizer solution to the root and stem position is that one end of the guide vane 6 has an arc-shaped structure and is tilted downward. When the fertilizer solution flows to the end along the path of the guide vane 6, the rotating blade 5 has already rotated a certain angle. At this time, the fertilizer solution guided by the guide vane 6 can flow downward at an angle to the ground at the root and stem position of the plant. Compared with the spraying method above the plant, this technical solution has better fertilizer utilization and more precise fertilization.

[0028] In this technical solution, the sprayed fertilizer mixture is impacted onto the rotating blades 5 by the downward-sloping arc-shaped nozzle structure 7 on both sides, and is then flung outward along the path of the guide plate 6. This allows the fertilizer solution, located in the lower part of the plant, to be accurately sprayed onto the plant roots and stems, making fertilization and irrigation more precise, environmentally friendly, economical, and reducing planting costs.

[0029] Example 2: The fertilization device mainly includes a truss 1. Fertilization mechanisms are set on both sides of the middle area of ​​the truss 1. The fertilization mechanism mainly includes a vertical pipe 3. A bottom column structure 4 is installed through the thread at the bottom of the vertical pipe 3. A rotating blade 5 is installed on the outer ring of the bottom column structure 4 and on the outer side of the vertical pipe 3 through a bearing structure. A spray hole structure 7 is opened at the bottom position on both sides of the outer ring of the vertical pipe 3. The spray hole structure 7 is specifically an arc-shaped hole structure that is inclined downward. The outer opening of the spray hole structure 7 faces the rotating blade 5. The rotating blade 5 is designed in an inclined state. A blade structure 16 is installed and fixed at a high position on the upper surface of the rotating blade 5.

[0030] In this embodiment, based on the basis of example 1, when the fertilizer solution is sprayed from the spray hole structure 7 and hits the upper surface of the rotating blade 5, the rotating blade 5 is impacted by the impact force and begins to rotate. Since the rotating blade 5 is located at the edge of the planting area and is inclined upward with the blade structure 16 during actual use, the blade structure 16 rotates synchronously when the rotating blade 5 rotates, thereby cutting the weeds at the edge of the planting area and near the plant roots. The weeds here are mainly for relatively hard weed plants. The blade structure 16 cuts the weed stems in an inclined upward state, which can cut the weeds, and then the fertilizer solution can be sprayed to the plant root position without or with less obstruction. At the same time, it can also clean the overgrown weeds to avoid the competition for nutrients between weeds and crops.

[0031] In this technical solution, the rotating blade 5 utilizes the impact force of the sprayed fertilizer, and the inclined upward blade structure 16 is designed and used. When spraying fertilizer, the weed stems are cut in a cutting state, which not only solves the problem that weed branches and leaves easily obstruct the sprayed fertilizer, but also moderately solves the problem that overgrown weeds easily compete with crops for nutrients.

[0032] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
