Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse planting technology, specifically to an agricultural greenhouse spraying device. Background Technology

[0002] In the field of modern agricultural greenhouse cultivation, spraying operations are a key link in ensuring crop growth and carrying out plant protection work.

[0003] Existing greenhouses mostly use manual watering or sprinkler irrigation, but these devices are not good at recycling natural water resources. For example, rainwater is directly lost from the roof during the rainy season and is not recycled. If this lost water could be used for irrigation, it would save a lot of planting costs.

[0004] Therefore, an agricultural greenhouse spraying device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an agricultural greenhouse spraying device that has the advantage of recycling and reusing natural water resources to reduce planting costs. It solves the problem that existing greenhouse spraying devices cause rainwater to be directly lost from the greenhouse roof during the rainy season without being effectively recycled, resulting in water waste and high planting costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural greenhouse spraying equipment, including a frame, on which spray heads are installed, and on which a water collection trough is installed, the water collection trough being used for storing spraying water;

[0007] A water guide pipe is connected to the water collection tank, and a connecting pipe and a connecting pipe are connected to the water guide pipe. The connecting pipe is used to connect the water guide pipe and the spray head.

[0008] Preferably, the frame includes an upright frame, on which a support frame is mounted, and the support frame is covered with a tarpaulin for sun and rain protection. An installation frame is fixed on the upright frame above the support frame for supporting and fixing the water collection tank.

[0009] In the design, the frame achieves functional integration through the combination of uprights, support frames, tarpaulins and mounting frames. The uprights provide the vertical support foundation for the whole, the support frames have the function of installing tarpaulins to complete the function of sunshade and rain protection for the greenhouse, and the mounting frames adopt a fixed connection with the uprights to provide stable load-bearing and installation points for the water collection tank.

[0010] Preferably, a manual drain valve is installed on the connecting water pipe, which is used to manually control the on / off state of the water flow in the connecting water pipe.

[0011] In the design, the water pipe is equipped with a manual drain valve to enable manual control of the water flow status within its own pipeline. The manual drain valve is characterized by convenient operation and direct on / off response. It is installed in series with the water pipe, providing users with an operation node for flexible control of the water circuit in non-automated operation scenarios.

[0012] Preferably, the spray head is equipped with an electric ball valve, which is used to control the start and stop of the spray and to connect the spray head to the connecting pipe. At the same time, a control switch that works with the electric ball valve is also required to control the electric ball valve.

[0013] In the design, the sprinkler heads are equipped with electric ball valves to achieve automated control of the start and stop of the sprinkler operation and the connection status with the connecting pipes. The electric ball valves have the ability to precisely adjust the water flow and dynamically adapt to the sprinkler flow rate.

[0014] Preferably, the water collection trough is fixed to the mounting frame by welding, with the opening of the water collection trough facing upward and the bottom corresponding to the top surface of the tarpaulin.

[0015] In the design, the water collection trough is fixed to the mounting frame by welding and the bottom is designed to correspond with the top surface of the tarpaulin, which realizes the efficient recycling of water resources on the roof. The water collection trough adopts a connection method of welding to the mounting frame, which not only ensures its own installation stability, but also improves the collection efficiency of rainwater on the roof, providing a prerequisite for the recycling of sprinkler water.

[0016] Preferably, the water guide pipe is detachably connected to the connecting water pipe and the connecting pipe via a quick-connect pipe fitting, and the water guide pipe, the connecting water pipe and the connecting pipe are made of corrosion-resistant plastic.

[0017] In the design, the water pipe is connected to the connecting water pipe and the connecting pipe through quick-connect pipe joints, and the use of corrosion-resistant plastic material realizes the flexible operation and maintenance and extended service life of the pipeline system. The quick-connect pipe joints have the characteristics of tool-free disassembly and assembly and high maintenance efficiency. The pipeline is made of corrosion-resistant plastic material, which allows the entire water circuit to maintain stable connection and corrosion resistance in complex environments such as high humidity in agriculture and pesticide residues, thereby reducing long-term operation and maintenance costs.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model, by setting up a frame, a water collection trough, a water guide pipe, a connecting water pipe, a connecting pipe, and a sprinkler head, uses the frame to support and install the water collection trough to collect natural water resources such as rainwater from the greenhouse roof during the rainy season and store it for sprinkler water. Then, the water stored in the water collection trough is transported to the sprinkler head through the pipeline system composed of the water guide pipe and the connecting pipe to complete the spraying operation. This achieves the effect of recycling and reusing natural water resources, and solves the problem of existing greenhouse sprinkler equipment where rainwater from the greenhouse roof is directly lost during the rainy season without being effectively recycled, resulting in water waste and high planting costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: an agricultural greenhouse spraying equipment, including a frame 1, a spray head 3 installed on the frame 1, and a water collection tank 2 installed on the frame 1 for storing spraying water;

[0028] A water guide pipe 21 is connected to the water collection tank 2. A connecting water pipe 22 and a connecting pipe 23 are connected to the water guide pipe 21. The connecting pipe 23 is used to connect the water guide pipe 21 and the spray head 3.

[0029] Specifically, by setting up a frame 1, a water collection trough 2, a water guide pipe 21, a connecting water pipe 22, a connecting pipe 23, and a sprinkler head 3, the frame 1 supports the installation of the water collection trough 2 to collect natural water resources such as rainwater from the greenhouse roof during the rainy season and store it for sprinkler water. Then, the water stored in the water collection trough 2 is transported to the sprinkler head 3 through the pipeline system composed of the water guide pipe 21 and the connecting pipe 23 to complete the spraying operation. This achieves the effect of recycling and reusing natural water resources, and solves the problem of existing greenhouse sprinkler equipment where rainwater from the greenhouse roof is directly lost during the rainy season without being effectively recycled, resulting in water waste and high planting costs.

[0030] Example 2

[0031] To achieve coordinated load-bearing of equipment structures and intelligent waterway control, such as Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the frame 1 includes a stand 11, a support frame 12 is installed on the stand 11, and a tarpaulin 13 is covered on the support frame 12. The tarpaulin 13 is used for sunshade and rain protection. An installation frame 14 is fixed on the stand 11 above the support frame 12. The installation frame 14 is used to support and fix the water collection tank 2.

[0032] Specifically, the frame 1 achieves functional integration through the combined design of the upright frame 11, the support frame 12, the tarpaulin 13 and the mounting frame 14. The upright frame 11 provides a vertical support foundation for the whole, the support frame 12 has the function of installing the tarpaulin 13 to complete the function of shading and rain protection for the greenhouse, and the mounting frame 14 adopts a fixed connection with the upright frame 11 to provide a stable bearing and installation point for the water collection tank 2.

[0033] Furthermore, a manual drain valve 221 is installed on the connecting water pipe 22. The manual drain valve 221 is used to manually control the on / off state of the water flow in the connecting water pipe 22. The manual drain valve 221 is reserved with an external interface to adapt to the external water source pipeline, and can replenish water to the water collection tank 2 through the pipeline.

[0034] Specifically, the connecting water pipe 22 achieves manual control of the water flow status within its own pipeline by installing a manual drain valve 221. The manual drain valve 221 not only has the conventional water circuit control characteristics of convenient operation and direct on / off response, but also supports connection to an external water source to replenish water to the collection tank 2 through a structure design with reserved external interfaces. Its series installation with the connecting water pipe 22 provides a manual water control node for non-automated operation scenarios, and can also ensure the water supply of the collection tank 2 with the help of an external water source when natural rainfall is insufficient, effectively expanding the adaptability of the equipment to complex water resource environments such as drought and low rainfall.

[0035] Furthermore, an electric ball valve 31 is installed on the spray head 3. The electric ball valve 31 is used to control the start and stop of the spray from the spray head 3 and to connect the spray head 3 with the connecting pipe 23.

[0036] Specifically, the sprinkler head 3 achieves automated control of the start and stop of the sprinkler operation and the connection status with the connecting pipe 23 by installing an electric ball valve 31. The electric ball valve 31 has the performance of precisely adjusting the water flow and dynamically adapting to the sprinkler flow rate.

[0037] Example 3

[0038] To achieve efficient rooftop water recycling and flexible operation and maintenance of the pipeline system, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the water collection trough 2 is fixed to the mounting frame 14 by welding. The opening of the water collection trough 2 faces upward and the bottom corresponds to the top surface of the tarpaulin 13. The water collection trough 2 is made of transparent plastic material, so that sunlight can shine through the water collection trough 2 onto the crops under the tarpaulin 13.

[0039] Specifically, the water collection trough 2 achieves efficient recycling of roof water resources through welding and fixing to the mounting frame 14 and the corresponding design of the bottom and the top surface of the tarpaulin 13. The water collection trough 2 adopts a connection method of welding to the mounting frame 14, which not only ensures its own installation stability, but also improves the collection efficiency of rainwater at the roof, providing a prerequisite for the recycling of sprinkler water.

[0040] Furthermore, the water pipe 21 is detachably connected to the connecting water pipe 22 and the connecting pipe 23 via quick-connect pipe fittings. The water pipe 21, the connecting water pipe 22, and the connecting pipe 23 are made of corrosion-resistant plastic.

[0041] Specifically, the water pipe 21 achieves flexible operation and maintenance and extended service life of the pipeline system through quick-connect pipe joints connecting to the water pipe 22 and the connecting pipe 23, and the selection of corrosion-resistant plastic material. The quick-connect pipe joints have the characteristics of tool-free disassembly and assembly and high maintenance efficiency. The pipeline is made of corrosion-resistant plastic material, which allows the entire water circuit to maintain stable connection and corrosion resistance in complex environments such as high humidity in agriculture and pesticide residues, thereby reducing long-term operation and maintenance costs.

[0042] When using this utility model, water is first collected by the water collection tank 2 above the frame 1: if it is the rainy season, rainwater falls directly into the water collection tank 2 for storage; if natural rainfall is insufficient, an external water source can be connected through the external interface of the manual drain valve 221 on the water pipe 22 to supplement the water required for spraying into the water collection tank 2.

[0043] Once the water collection meets the operational requirements, the electric ball valve 31 on the sprinkler head 3 presets parameters such as spraying time and flow rate. The electric ball valve 31 then automatically controls the start and stop of the sprinkler head 3 and the water flow, achieving timed and quantitative irrigation or plant protection spraying.

[0044] When the water level in the collection tank 2 is too high, first close the electric ball valve 31, then operate the manual drain valve 221 to quickly empty the collection tank 2 and collect rainwater.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
