Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, and in particular to a timed and quantitative irrigation and fertilization device for greenhouse facilities. Background Technology

[0002] In the early stages of greenhouse agriculture development, manual irrigation and fertilization were the most common methods. This method is labor-intensive and requires a lot of manpower. Moreover, manual operation makes it difficult to accurately control the amount of irrigation water and fertilizer, which can easily lead to uneven irrigation, excessive or insufficient fertilization, resulting in water waste and low fertilizer utilization, thus affecting crop growth and yield.

[0003] With the development of agricultural technology, some common irrigation equipment has been combined with fertilizer tanks. For example, Chinese patent CN216087649U discloses an integrated water and fertilizer irrigation and fertilization device for smart greenhouses. The pump body can draw water and fertilizer from the water tank and fertilizer tank through the first and second conduits, and then spray the water and fertilizer out through the nozzles at the bottom of the first and second spray pipes to irrigate and fertilize the plants.

[0004] Regarding the aforementioned technologies, since the spatial position of the nozzles is fixed, the area that can be covered during subsequent irrigation and fertilization is relatively limited, which increases the cost of large-scale greenhouse planting. Furthermore, the spraying trajectory remains unchanged, resulting in certain blind spots and making it impossible to achieve full coverage of the required irrigation surface.

[0005] Therefore, a timed and quantitative irrigation and fertilization device for greenhouses is needed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a timed and quantitative irrigation and fertilization device for greenhouse facilities to solve the problem of poor subsequent irrigation and fertilization effect caused by the fixed spatial position of the nozzle.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a timed and quantitative irrigation and fertilization device for greenhouse facilities, including a three-way pipe for connecting various pipelines, both ends of the three-way pipe are connected to inlet pipes for conveying a mixture of fertilizer and water, the other end of the three-way pipe is connected to an outlet pipe group, and an irrigation mechanism is provided at the upper end of the outlet pipe group.

[0008] The discharge pipe assembly includes a connecting pipe, and a transmission component is provided on the inner side of the connecting pipe.

[0009] The irrigation mechanism includes a hollow pipe rotatably connected to a connecting pipe. The hollow pipe is connected to the connecting pipe. A bevel gear is bolted to the outer wall of the hollow pipe and meshes with a transmission component. An output pipe is symmetrically welded to the outer wall of the hollow pipe and connected to it. An output pipe is provided on the outer wall of the output pipe and connected to it. A nozzle is threaded onto the upper end of the output pipe. As the fertilizer flows through the connecting pipe, it continuously pushes the transmission component to rotate, forcing the transmission component to drive the bevel gear to rotate. Ultimately, the two sets of nozzles rotate around the axis of the hollow pipe, creating an outward-throwing effect. This avoids a fixed spray trajectory, effectively expanding the irrigation area and reducing equipment operating costs while ensuring full coverage of the required irrigation surface.

[0010] Preferably, a guide block is fixedly installed on the inner wall of the connecting pipe 1. The transmission component includes a driven rod that passes through the connecting pipe 1 and is rotatably connected. Multiple sets of flow-blocking blades are symmetrically arranged on the outer wall of the driven rod. A bevel gear 2 is fixedly installed at one end of the driven rod. The bevel gear 2 meshes with the bevel gear 1. The guide block guides the fertilizer water flowing in the connecting pipe 1, thereby causing the fertilizer water to continuously generate a pushing force on the flow-blocking blades so that it can pass through. This causes the multiple sets of flow-blocking blades to drive the driven rod to rotate, and the driven rod in turn drives the bevel gear 2 to rotate. Since the bevel gear 2 and the bevel gear 1 are in a meshing state, the two sets of nozzles ultimately rotate in a circle around the axis of the cavity pipe.

[0011] Preferably, output pipe one and output pipe two are slidably connected, and a bidirectional electric telescopic rod is fixedly installed at the upper end of the cavity pipe. The two ends of the bidirectional electric telescopic rod are respectively fixedly connected to the outer wall of output pipe two. When the two sets of nozzles rotate around the axis of the cavity pipe, the two sets of output pipe two are moved horizontally by the bidirectional electric telescopic rod, which can further expand the irrigation range of the nozzles.

[0012] Preferably, the upper end face of the connecting pipe is provided with an annular groove, and the lower end face of the cavity pipe is fixedly installed with a ring. The ring matches the annular groove and is rotatably connected, which can effectively improve the sealing performance between the two and prevent the entry of external impurities, thus affecting the normal flow rate of the channel.

[0013] Preferably, a protective box is fixedly installed on the outer wall of the connecting pipe, and a cover is hinged on one side of the protective box. The protective box can effectively protect the meshing part of the transmission component and the bevel gear, thereby ensuring normal operation. The cover also facilitates maintenance and replacement by personnel.

[0014] Preferably, a solenoid valve is fixedly installed at the lower end of the first connecting pipe, and a second connecting pipe is fixedly installed at the lower end of the solenoid valve. The second connecting pipe is fixedly connected to the three-way pipe. By setting the solenoid valve, the fertilizer and water can be controlled to be input into the first connecting pipe in a timely and quantitative manner, so as to avoid the situation of too much or too little fertilizer application, which would lead to water waste and low fertilizer utilization rate, affecting crop growth and yield.

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

[0016] This utility model proposes a timed and quantitative irrigation and fertilization device for greenhouses, which causes two sets of nozzles to rotate in a circular motion around the axis of the hollow tube, creating an outward-throwing effect. This avoids a fixed spray trajectory, effectively expanding the irrigation area and reducing equipment operating costs while ensuring full coverage of the required irrigation surface.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] According to one embodiment of the present invention, in conjunction with Figure 1-4 The device for timed and quantitative irrigation and fertilization of a greenhouse includes a three-way pipe 1 for connecting various pipelines. Both ends of the three-way pipe 1 are connected to inlet pipes 2 for conveying a mixture of fertilizer and water. The other end of the three-way pipe 1 is connected to an outlet pipe group 3. An irrigation mechanism 4 is provided at the upper end of the outlet pipe group 3.

[0026] The discharge pipe assembly 3 includes a connecting pipe 33, and a transmission component 36 is provided on the inner side of the connecting pipe 33.

[0027] The irrigation mechanism 4 includes a hollow pipe 41 rotatably connected to the connecting pipe 33. The hollow pipe 41 is connected to the connecting pipe 33. A bevel gear 43 is bolted to the outer wall of the hollow pipe 41. The bevel gear 43 meshes with the transmission component 36. An output pipe 44 is symmetrically welded to the outer wall of the hollow pipe 41 and is connected to it. An output pipe 45 is provided on the outer wall of the output pipe 44 and is connected to it. A nozzle 46 is threaded on the upper end of the output pipe 45. As the fertilizer flows through the connecting pipe 33, it will continuously push the transmission component 36 to rotate, forcing the transmission component 36 to drive the bevel gear 43 to rotate. Finally, the two sets of nozzles 46 rotate in a circle around the axis of the hollow pipe 41, forming an outward throwing effect. This avoids the fixed spray trajectory and effectively expands the irrigation area while ensuring full coverage of the required irrigation surface and reducing equipment operating costs.

[0028] Combination Figure 3-4 As shown, a guide block 34 is fixedly installed on the inner wall of the connecting pipe 33. The transmission component 36 includes a driven rod 363 that passes through the connecting pipe 33 and is rotatably connected. Multiple sets of flow-blocking blades 362 are symmetrically arranged on the outer wall of the driven rod 363. A bevel gear 361 is fixedly installed at one end of the driven rod 363. The bevel gear 361 meshes with the bevel gear 43. The guide block 34 guides the fertilizer water flowing in the connecting pipe 33, thereby causing the fertilizer water to continuously generate a pushing force on the flow-blocking blades 362 so that it can pass through. This causes the multiple sets of flow-blocking blades 362 to drive the driven rod 363 to rotate. The driven rod 363 then drives the bevel gear 361 to rotate. Since the bevel gear 361 and the bevel gear 43 are meshed, the two sets of nozzles 46 eventually rotate in a circle around the axis of the cavity pipe 41.

[0029] Combination Figure 4As shown, output pipe 1 44 and output pipe 2 45 are slidably connected. A bidirectional electric telescopic rod 47 is fixedly installed at the upper end of the cavity pipe 41. The two ends of the bidirectional electric telescopic rod 47 are fixedly connected to the outer wall of output pipe 2 45 respectively. When the two sets of nozzles 46 rotate around the axis of the cavity pipe 41, the two sets of output pipe 2 45 are moved horizontally by the bidirectional electric telescopic rod 47, which can further expand the irrigation range of the nozzles 46.

[0030] Combination Figure 3-4 As shown, an annular groove 35 is provided on the upper end face of the connecting pipe 33, and an annular ring 42 is fixedly installed on the lower end face of the cavity pipe 41. The annular ring 42 matches and rotates with the annular groove 35, which can effectively improve the sealing performance between the two and prevent the entry of external impurities, thus affecting the normal flow rate of the channel.

[0031] Combination Figure 3 As shown, a protective box 37 is fixedly installed on the outer wall of the connecting pipe 33. A box cover 371 is hinged on one side of the protective box 37. The protective box 37 can effectively protect the meshing part of the transmission component 36 and the bevel gear 43, thereby ensuring normal operation. The box cover 371 facilitates maintenance and replacement by personnel.

[0032] Combination Figure 2 As shown, a solenoid valve 32 is fixedly installed at the lower end of the connecting pipe 33, and a connecting pipe 31 is fixedly installed at the lower end of the solenoid valve 32. The connecting pipe 31 is fixedly connected to the three-way pipe 1. By setting the solenoid valve 32, the fertilizer and water can be controlled to be input into the connecting pipe 33 in a timely and quantitative manner, so as to avoid the situation of too much or too little fertilizer application, which would lead to water waste and low fertilizer utilization rate, affecting crop growth and yield.

[0033] In this embodiment, a three-way pipe 1 is included for connecting various pipelines. Both ends of the three-way pipe 1 are connected to inlet pipes 2 for conveying a mixture of fertilizer and water. The other end of the three-way pipe 1 is connected to an outlet pipe assembly 3. An irrigation mechanism 4 is provided at the upper end of the outlet pipe assembly 3.

[0034] The discharge pipe assembly 3 includes a connecting pipe 33, and a transmission component 36 is provided on the inner side of the connecting pipe 33.

[0035] The irrigation mechanism 4 includes a hollow pipe 41 rotatably connected to the connecting pipe 33. The hollow pipe 41 is connected to the connecting pipe 33. A bevel gear 43 is bolted to the outer wall of the hollow pipe 41. The bevel gear 43 meshes with the transmission component 36. An output pipe 44 is symmetrically welded to the outer wall of the hollow pipe 41 and is connected to it. An output pipe 45 is provided on the outer wall of the output pipe 44 and is connected to it. A nozzle 46 is threaded on the upper end of the output pipe 45. As the fertilizer flows through the connecting pipe 33, it will continuously push the transmission component 36 to rotate, forcing the transmission component 36 to drive the bevel gear 43 to rotate. Finally, the two sets of nozzles 46 rotate in a circle around the axis of the hollow pipe 41, forming an outward throwing effect. This avoids the fixed spray trajectory and effectively expands the irrigation area while ensuring full coverage of the required irrigation surface and reducing equipment operating costs.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
