Description

Technical field:

[0001] The utility model relates to the technical field of forage planting equipment, in particular to a forage disc uniform irrigation device. Background technology:

[0002] Existing hydroponic grass usually places multiple grass cultivation trays side by side for centralized large-scale cultivation to improve grass production efficiency; a water spraying device is provided above each grass tray, and water is transported to the nozzle above the corresponding grass tray through a water pump to irrigate the grass below it in a timely and quantitative manner.

[0003] Since irrigation water usually comes from natural water sources such as rivers, the water is hard and easily scaled, and contains a lot of impurities such as mud and sand. The nozzles of existing water spraying devices are often clogged with mud and scale, resulting in a significant reduction in the amount of watering the grass tray under the clogged nozzles, while other unblocked grass seedling trays are watered too much, which is easy to overflow from the overflow ports of the seedling trays, resulting in a waste of water resources. In order to reduce the failure of the water spraying device, the filter device and the nozzle need to be frequently disassembled and cleaned, which is cumbersome. In addition, in order to ensure the uniformity of water spraying irrigation, the traditional water spraying system needs to set up throttle valves and other devices to control the pressure balance of each point in the pipeline. The pipeline area is small, and the pressure of each water outlet changes after blockage, resulting in different water spraying volumes per unit time, so it is more likely to cause uneven irrigation. Utility model content:

[0004] The utility model aims to provide a grass disc uniform irrigation device to solve the problems existing in the prior art.

[0005] The utility model is implemented by the following technical scheme: a forage disc uniform irrigation device, comprising a water storage tank, an overflow baffle, a first end cover, a second end cover and a siphon tube; the water storage tank is open at both ends and the top, an overflow baffle is integrally formed at the opening at one end of the water storage tank, a first end cover and a second end cover are respectively movably and sealedly provided at the openings at both ends of the water storage tank, a water outlet is provided at the bottom of the water storage tank, and the siphon tube is sealedly connected to the water outlet at the bottom of the water storage tank; the siphon tube comprises a first vertical pipe, a second vertical pipe and two curved pipes, the bottom end of the first vertical pipe is connected to the water outlet at the bottom of the water storage tank through the curved pipe, the top end of the first vertical pipe is connected to the top end of the second vertical pipe through the curved pipe, the height of the curved pipe at the top of the first vertical pipe is lower than the height of the upper end edge of the outer wall of the water storage tank, the bottom end of the second vertical pipe is lower than the height of the bottom surface of the water storage tank, and the height of the overflow baffle is lower than the height of the curved pipe at the top of the first vertical pipe.

[0006] Furthermore, a card slot is provided on both side edges of the opening at one end of the water storage tank, and a protrusion is integrally formed on both side edges of the opening at the other end; a groove matching the protrusion is provided on the first end cover, and a boss matching the card slot is integrally formed on the second end cover.

[0007] Furthermore, a cofferdam is provided at the bottom of the water storage tank and around the water outlet.

[0008] Furthermore, it also includes a top cover arranged on the top of the water storage tank, and a vent hole is opened on the top cover.

[0009] Furthermore, it also includes a sewage pipe arranged at the bottom of the water storage tank, the sewage pipe is connected to the bottom of the water storage tank, the bottom end of the sewage pipe is sealed with a sewage cover, and the sewage cover is connected to the sewage pipe through threads.

[0010] The advantages of the utility model are as follows: the water in the water storage tank is sucked out by the siphon principle through the siphon tube, replacing the nozzle and throttle valve and other devices in the traditional quantitative water spraying device. Compared with the traditional scheme, the cross-sectional area of ​​the water flow path is large, which reduces the probability of clogging by impurities and scale. At the same time, a cofferdam and a top cover are provided to prevent mud and scale from entering the siphon tube, and effectively prevent foreign impurities and debris from falling into the water storage tank and clogging the water outlet of the water storage tank, further reducing the probability of clogging, ensuring that each forage disk evenly distributes a certain amount of water, and ensuring that the overall forage is evenly irrigated.

[0018] like Figure 1 , Figure 2 As shown: a forage disc uniform irrigation device, which includes a water storage tank 1, an overflow baffle 2, a first end cover 3, a second end cover 4 and a siphon 5; the water storage tank 1 is open at both ends and the top, and the overflow baffle 2 is integrally formed at the opening of one end of the water storage tank 1, and the first end cover 3 and the second end cover 4 are respectively movably sealed at the openings of both ends of the water storage tank 1, the overflow baffle 2 is placed between the first end cover 3 and the second end cover 4, and the second end cover 4 is fitted with the overflow baffle 2, and the edges of the two sides of the opening at one end of the water storage tank 1 are provided with a card slot 102, and the edges of the two sides of the opening at the other end are integrally formed with a protrusion 103, and the card slots 102 of two adjacent water storage tanks 1 It matches with the protrusion 103. When in use, multiple water storage tanks 1 are spliced ​​together and are sealed and connected to each other with the protrusion 103 through the slots 102 at the openings on both sides; the first end cover 3 is provided with a groove matching the protrusion 103, and the second end cover 4 is integrally formed with a boss matching the slot 102. The first end cover 3 and the second end cover 4 are sealed and connected to the openings on both sides of the water storage tank 1 through their integrally formed grooves and bosses. When multiple water storage tanks 1 are connected to each other for use, the first end cover 3 and the second end cover 4 are respectively sealed and connected to the openings on both sides of the two water storage tanks 1 at both ends to form an integral water storage container for temporarily storing water for irrigating pasture.

[0019] like Figure 3As shown: a water outlet 101 is provided at the bottom of the water tank 1, and the siphon 5 is sealedly connected to the water outlet 101 at the bottom of the water tank 1; the siphon 5 includes a first vertical pipe 501, a second vertical pipe 502 and two elbows, the bottom end of the first vertical pipe 501 is connected to the water outlet 101 at the bottom of the water tank 1 through the elbow, the top end of the first vertical pipe 501 is connected to the top end of the second vertical pipe 502 through the elbow, the height of the elbow at the top of the first vertical pipe 501 is lower than the height of the upper end edge of the outer wall of the water tank 1, the bottom end of the second vertical pipe 502 is lower than the height of the bottom surface of the water tank 1, and the height of the overflow baffle 2 is lower than The height of the bend at the top of the first vertical pipe 501; the siphon tube 5 uses the siphon principle to discharge the water in the water tank 1 after the water level exceeds the height of the bend at the top of the first vertical pipe 501. Since the bottom of the second vertical pipe 502 is lower than the height of the bottom surface of the water tank 1, the siphon tube 5 can basically completely drain the water in the water tank 1. The second vertical pipe 502 injects water into its corresponding hay plate. One water tank 1 corresponds to one hay plate. The water tanks 1 are separated from each other by overflow baffles 2. Since the volume of each water tank 1 is the same, uniform and quantitative irrigation of each hay plate can be achieved.

[0020] The specific working principle is as follows: at the same horizontal height position above the forage disk, a water tank 1 is correspondingly arranged for each forage disk, and the water tanks 1 are sealed and connected to each other through the slots 102 and the protrusions 103 at both ends, and the two ends of the head and tail water tanks are sealed and connected to the openings on both sides of the two water tanks 1 at both ends using the first end cover 3 and the second end cover 4, respectively, to form an integral water storage container; the second vertical pipe 502 of each siphon tube 5 is aligned with the forage disk so that water can flow into the corresponding forage disk; when watering is needed, water is poured into any of the water tanks 1, and the water level first rises to the overflow baffle 2 of the water tank 1 , since the water level has not reached the height of the top of the siphon tube 5, the siphon effect will not be triggered, and the water will overflow through the overflow baffle 2 and flow into the adjacent water storage tank 1 until the liquid level of all water storage tanks 1 at the same level exceeds the overflow baffle 2, and the liquid level in each water storage tank 1 begins to rise synchronously. Since the bottom end of the first vertical pipe 501 is connected to the water storage tank 1 through a bend, the liquid level in the first vertical pipe 501 will also rise. When the liquid level exceeds the height of the bend at the top of the first vertical pipe 501, the siphon effect will be triggered, and the siphon tubes 5 corresponding to all the grass disks will start to suck water out of the water storage tank 1, irrigating the grass disks in equal amounts. Since there is no need for nozzles and throttle valves to adjust, the passage area of ​​the water flow is relatively large and is not affected by water pressure or other factors, thus greatly reducing the possibility of blockage and making the overall operation more reliable.

[0021] like Figure 4As shown: in order to reduce the possibility of silt impurities clogging the suction valve 5 and affecting normal operation, a cofferdam 104 is provided at the bottom of the water storage tank 1 and around the water outlet 101. During the water storage process, the silt impurities will naturally settle and remain at the bottom of the water storage tank 1 and the periphery of the cofferdam 104; the top cover 6 on the top of the water storage tank 1 can prevent impurities from falling into the water storage tank 1. A vent 601 is provided on the top cover 6. The vent 601 can ensure that the air pressure in the water storage tank 1 is kept equal to the external air pressure when the siphon 5 is pumping water. A sewage pipe 105 is provided at the bottom of the tank 1, and the sewage pipe 105 is connected to the bottom of the water storage tank 1. A sewage cover 106 is sealed at the bottom of the sewage pipe 105. The sewage cover 106 is connected to the sewage pipe 105 through a thread. When water is normally stored, the sewage cover 106 is tightened on the sewage outlet 105. When sewage needs to be cleaned, the silt and impurities deposited in the water storage tank 1 can be emptied through the sewage pipe 105. The sewage cover 106 is opened to rinse the inside of the water storage tank 1 with water, and the sewage and silt impurities can be discharged from the sewage pipe 105.
