Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a watering device for a seedling-raising greenhouse. Background Technique

[0002] With the rapid development of agriculture in China, the technology of agricultural seedling raising has become more and more mature. In order to grow crops in winter, a seedling-raising greenhouse is used for seedling raising and other work in winter. In order to ensure the water for the early growth of seedlings, it is necessary to water the crops. Usually, a main water delivery pipe is set at the top of the greenhouse, and a hanging rubber hose is installed on the main water delivery pipe. The water inlet end of the nozzle is directly inserted into the free end of the rubber hose to realize the convenient fixing and disassembly of the rubber hose and the nozzle. The nozzle atomizes the water that flows through the main water delivery pipe, the rubber hose in sequence and enters the nozzle under a predetermined pressure. Thus, the watering device composed of the rubber hose and the nozzle can effectively spray water to the crop planting area in the greenhouse.

[0003] However, the watering device composed of the above rubber hose and the nozzle has the following technical problems: the temperature in the seedling-raising greenhouse is relatively high. For example, the temperature near the top of the greenhouse in the early summer is between 30 degrees and 40 degrees. The rubber hose becomes soft and deformed under the influence of temperature, resulting in a decrease in the tightness between the rubber hose and the nozzle. At the same time, under the action of water pressure, the nozzle and the rubber hose fall off, and water sprays out in the form of a water column from the free end of the rubber hose, resulting in a reduction in the effective area of water spraying and ultimately affecting the watering efficiency. Summary of the Utility Model

[0004] In view of this, it is necessary to provide a watering device for a seedling-raising greenhouse that will not cause the nozzle to fall off due to the heat deformation of the rubber hose.

The first fixing ring is used to be clamped with the bottom surface of the first fixing head. The second fixing ring clamps the outside of the second fixing head. A thread is opened on the outside of the bottom end of the locking member. A first fixing cover is provided on the outside of the second fixing head.

A third fixing cover is provided at the bottom end of the connecting member. Threads are provided inside the third fixing cover to fixedly connect the mounting member and the connecting member by means of threaded fixation.

[0008] Preferably, two corresponding-sized rotating handles are symmetrically provided on the outer sides of the first fixing cover, the third fixing cover, the fastener, and the mounting member.

[0009] Preferably, a counterweight is further installed at the top end of the locking member to increase the weight at the bottom end of the shunt pipeline.

[0010] Preferably, the counterweight has multiple specifications to select a counterweight with a corresponding specification according to the water pressure in different seedling-raising greenhouses.

[0011] Preferably, a water valve is further provided on the connecting member to adjust the water flow rate flowing to the nozzle.

[0012] In the above-mentioned sprinkler device for a seedling-raising greenhouse, there is a main flow pipe and several flow-dividing components.

Detailed implementation manners

[0022] The following further elaborates in detail on the technical solutions and technical effects of the embodiments of the present utility model in conjunction with the drawings of the present utility model.

[0023] Please refer to Figures 1 to 7, the present utility model provides a sprinkling device 10 for a seedling-raising greenhouse, which includes a main flow pipe 20 and several shunt members 30. Each shunt member 30 includes a shunt pipeline 31, a locking member 32, a connecting member 33 and a nozzle assembly 34. The main flow pipe 20 is horizontally arranged at the top of the seedling-raising greenhouse. A number of downward-facing shunt branch pipes 21 are provided on the main flow pipe 20. The top of the shunt pipeline 31 is communicated with one of the shunt branch pipes 21. The top of the connecting member 33 is successively provided with a frustum-shaped first fixing head 331 and a second fixing head 332 from top to bottom. The first fixing head 331 and the second fixing head 332 extend into the shunt pipeline 31 from the bottom end of the shunt pipeline 31 to clamp the first fixing head 331 and the second fixing head 332 on the inner wall of the shunt pipeline 31, so as to fixedly connect the connecting member 33 and the shunt pipeline 31. The locking member 32 is in a cylindrical shape and is sleeved on the shunt pipeline 31. A first fixing ring 321 and a second fixing ring 322 are provided inside the locking member 32. The first fixing ring 321 is used to be clamped with the bottom surface of the first fixing head 331, and the second fixing ring 322 clamps the outside of the second fixing head 332 to prevent the first fixing head 331 and the second fixing head 332 from falling off from the shunt pipeline 31. Threads are provided on the outside of the bottom end of the locking member 32, and threads are provided on the inside of a first fixing cover 333 provided on the outside of the second fixing head 332 to fixedly connect the locking member 32 and the first fixing cover 333 by means of threaded connection. In this way, the shunt pipeline 31 is sleeved on the first fixing head 331 and the second fixing head 332, and the first fixing head 331 and the second fixing head 332 are clamped with the inner wall of the shunt pipeline 31 by the pressure applied from the outer wall to the inner wall of the shunt pipeline 31, so that the connecting member 33 and the shunt pipeline 31 are fixedly connected; an inward pressure is applied to the outer wall of the shunt branch pipe 21 by the first fixing ring 321 and the second fixing ring 322 to enhance the connection between the shunt pipeline 31 and the nozzle assembly 34; through the threaded connection between the bottom end of the locking member 32 and the inside of the first fixing cover 333, not only the locking member 32 and the connecting member 33 are fixedly connected, but also the part of the shunt pipeline 31 connected to the nozzle assembly 34 can be locked in the first fixing cover 333 by the first fixing ring 321 and the second fixing ring 322, so that when the shunt pipeline 31 is thermally deformed, the connecting member 33 will not fall off from the shunt pipeline 31, and the nozzle assembly 34 installed at the bottom of the connecting member 33 will not fall off either.

[0024] Please refer to Figures 2 to 4, Further, a frustum-shaped third fixing head 22 is provided at the bottom end of each shunt branch pipe 21. The third fixing head 22 extends into each shunt pipeline 31 from the top end of each shunt pipeline 31 to fixedly connect each shunt branch pipe 21 and each shunt pipeline 31. A fastener 311 is sleeved on the top end of each shunt pipeline 31. A third fixing ring 312 is provided inside the fastener 311. The third fixing ring 312 is used to engage with the top surface of the third fixing head 22 to prevent the third fixing head 22 from detaching from the shunt pipeline 31. Threads are provided on the outer side of the top end of the fastener 311. A second fixing cover 23 is provided on the outer side of the shunt branch pipe 21 above the third fixing head 22. Threads are provided inside the second fixing cover 23 to fixedly connect the fastener 311 and the second fixing cover 23 by means of threaded connection. In this way, the third fixing head 22 is clamped on the inner wall of the shunt pipeline 31, and the third fixing ring 312 applies an inward pressure to the outer circle of the shunt pipeline 31, so that the connection between the third fixing head 22 and the shunt pipeline 31 is tighter. And through the threaded connection between the second fixing cover 23 and the fastener 311, the part where the shunt pipeline 31 is connected to the shunt branch pipe 21 is locked in the second fixing cover 23 to prevent the shunt pipeline 31 from detaching from the shunt branch pipe 21 due to the thermal deformation of the shunt pipeline 31.

[0025] Please refer to Figure 8 , Further, the nozzle assembly 34 includes a mounting member 341 and a rotating nozzle 342. The rotating nozzle 342 is rotatably mounted at the bottom end of the mounting member 341. When watering, the water flow impacts the rotating nozzle 342 downward, so that the rotating nozzle 342 can rotate around the mounting member 341 as the axis, thereby improving the efficiency of watering the crops. A cylindrical fourth fixing head 3411 is provided at the top end of the mounting member 341. Threads are provided on the outer side of the fourth fixing head 3411. A third fixing cover 334 is provided at the bottom end of the connecting member 33. Threads are provided inside the third fixing cover 334 to fixedly connect the mounting member 341 and the connecting member 33 by means of threaded fixation.

[0026] In this embodiment, two corresponding-sized rotating handles are symmetrically provided on the outer sides of the first fixing cover 333, the third fixing cover 334, the fastener 311, and the mounting member 341, so as to facilitate the threaded fixation of the first fixing cover 333, the third fixing cover 334, the fastener 311, and the mounting member 341 by turning the rotating handle quickly when installing the sprinkler device 10 for the seedling greenhouse, so as to facilitate the assembly of the sprinkler device 10 for the seedling greenhouse.

[0027] Please refer to Figure 4 , Further, a counterweight 323 is also installed at the top end of the locking member 32, which is used to increase the weight at the bottom end of the shunt pipeline to prevent the shunt pipeline 31 from shaking around due to the reaction force of the water spraying outward from the nozzle assembly 34 during the spraying process, and ensure that the nozzle assembly 34 waters the crops within a predetermined range.

[0028] In this embodiment, the counterweight 323 has multiple specifications to select a corresponding specification of the counterweight 323 according to the water pressure of different seedling-raising greenhouses, thereby preventing the counterweight 323 from being unable to press the bottom end of the flow splitting pipeline 31 due to excessive water pressure.

[0029] In this embodiment, the nozzle assembly 34 is made of plastic material and will not be deformed by heat due to the temperature in the seedling-raising greenhouse.

[0030] Please refer to Figures 6 to 7 , in this embodiment, a water valve 335 is further provided on the connecting member 33 for adjusting the water flow rate flowing to the nozzle. By adjusting the water flow rate, when the water flow rate increases, the watering range of the rotating nozzle 342 increases, and when the water flow rate decreases, the watering range of the rotating nozzle 342 decreases.

[0031] In one embodiment, the problem of the nozzle assembly 34 falling off caused by the heat deformation of the flow splitting pipeline 31 is avoided by replacing the flow splitting pipeline 31 with a stainless steel material, but that will make the cost of the sprinkler device 10 in the seedling-raising greenhouse too high.

[0032] During installation, first connect the flow splitting pipeline 31 to the main pipeline 20. Specifically, first insert the third fixing head 22 from the top of the flow splitting pipeline 31 into the flow splitting pipeline 31, and then rotate the fastener 311 so that the top end of the fastener 311 is thread-fixed to the second fixing cover 23 to complete the connection between the flow splitting pipeline 31 and the main pipeline 20; then connect the connecting member 33 to the flow splitting pipeline 31. Specifically, first insert the first solid head and the second fixing head 332 from the bottom of the flow splitting pipeline 31 into the flow splitting pipeline 31, then move the locking member 32 downward, and then rotate the first fixing cover 333 so that the first fixing cover 333 is thread-fixed to the bottom end of the locking member 32 to complete the connection between the connecting member 33 and the flow splitting pipeline 31; then connect the mounting member 341 to the connecting member 33. Specifically, align and screw the fourth fixing head 3411 into the third fixing cover 334, and complete the connection between the mounting member 341 and the connecting member 33 through the threaded fixed connection between the outside of the fourth fixing head 3411 and the inside of the third fixing cover 334, thereby completing the installation of the sprinkler device 10 in the seedling-raising greenhouse.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
