Description

Technical Field

[0001] The invention relates to the technical field of corn planting, and in particular to a quantitative irrigation device for planting spring corn in dry land. Background Art

[0002] Corn is an annual tall herbaceous plant of the genus Zea of ​​the family Gramineae. It is also known as corn, corn, corn, pearl rice, etc. It is cultivated in various parts of China and widely planted in tropical and temperate regions around the world. It is an important cereal. Corn has strong drought resistance, cold resistance, and barrenness resistance, as well as excellent environmental adaptability, and has high nutritional value.

[0003] Before sowing spring corn in dryland, scientific and efficient irrigation should be carried out according to the soil moisture conditions. For plots with good soil moisture conditions, land should be prepared in time before sowing; in autumn, soil should be compacted in time to conserve moisture; in low-lying areas and areas prone to spring flooding, the soil should be plowed and aired as early as possible, and ridges should be built to disperse moisture to ensure timely sowing. Corn is a major water-consuming crop, and it should be based on good soil moisture conditions, with efficient and energy-saving irrigation as the core, and the traditional flooding before spring sowing should be cancelled. Therefore, when irrigating spring corn in dryland, efficient irrigation methods such as pipe irrigation, ridge irrigation, and shallow buried drip irrigation should be used. When these irrigation methods are selected, quantitative irrigation devices are required to perform corresponding irrigation operations on the corn;

[0004] After searching, a small quota irrigation method and special facilities for corn were disclosed in a Chinese patent, the publication number of which is CN102487785B. The method can reduce the amount of water used for corn germination and make corn germination earlier, thereby increasing the yield; the irrigation water quota can be freely adjusted to improve the utilization efficiency of irrigation water; the special facilities of the present invention can effectively fix the infiltration irrigation water storage belt in the corn field to avoid being blown away by the wind and affecting the irrigation effect, and can also play the role of covering and collecting rainwater, which is beneficial to retaining soil moisture, reducing ineffective soil evaporation and improving the utilization efficiency of rainfall;

After the inner bottom is snapped in, the irrigation water is poured to the top of the small water distribution tray 2044. The bottom end of the water storage box 2045 is fixedly connected to the large water distribution tray 2046, and the large water distribution tray 2046 is also used to spread the irrigation water flowing to its top. The bottom end of the outer wall of the connecting rod 2042 is sleeved with a support spring 2047, and the support spring 2047 is used to support the bottom end of the large water distribution tray 2046. The water outlet pipe is fixedly connected to the inner top of the filter tank 201, and the water outlet pipe is used to discharge the irrigation water transported to the interior to the top of the large water distribution tray 2046. The top and bottom ends of the support spring 2047 are respectively fixedly connected to the bottom end of the large water distribution tray 2046 and the top of the small water distribution tray 2044.

[0042] In this embodiment, preferably, a plurality of water outlets 206 are evenly provided at the bottom end of the water outlet pipe, and a card slot matching the specifications of the ball head 2043 is provided at the inner bottom end of the water storage box 2045, and the card slot is used to card the ball head 2043, and the irrigation water stored in the water storage box 2045 can be discharged to the top of the small water tray 2044, and the inner wall of the card slot is processed with a layer of rubber waterproof pad, and the rubber waterproof pad is used to enhance the sealing effect between the ball head 2043 and the card slot, and the outer wall bottom end of the ball head 2043 can be embedded in the inner part of the card slot, and the large water tray 2044 can be connected to the card slot. The large water tray 2046 is processed into a disc shape as a whole, and a water storage tank with a certain degree of protrusion is processed at the center of the large water tray 2046, which can enable the large water tray 2046 to have a certain degree of water storage capacity. When the irrigation water flow discharged to its top is not fierce, the irrigation water can be evenly distributed to the top of the filter material inside the filter tank 201 by relying on the large water tray 2046 alone. The tops of the large water tray 2046, the large water tray 2046 and the small water tray 2044 are both provided with a plurality of guide grooves in a circular array, and the guide grooves are used to guide the flow direction of the irrigation water.

[0043] In this embodiment, preferably, the interior of the filter tank 201 is filled with filter materials composed of sand, quartz sand and anthracite, which can filter out particulate matter contained in the irrigation water and reduce the turbidity of the filtered water. At the same time, it can also adsorb fine impurities contained in the irrigation water, thereby improving the filtering effect of the irrigation water. The water collector 205 is overall funnel-shaped and arranged at the bottom of the filter tank 201, thereby enhancing the collection effect of the water collector 205 on the filtered irrigation water.

[0044] In summary, when it is necessary to irrigate the corn plants quantitatively, when replenishing the irrigation water into the water storage barrel 301 in the irrigation mechanism 3, the irrigation water needs to be filtered first. After the irrigation water is transported to the inside of the filter tank 201 in the filter mechanism 2 by the water pump, the irrigation water will flow to the inside of the water outlet pipe in the water distribution component 204 through the water inlet 202 opened at the top of the filter tank 201, and through the cooperation of the water outlet pipe, the irrigation water can be discharged to the top of the large water distribution tray 2046. When the irrigation water flow rate is relatively low, not much irrigation water can be accumulated inside the top of the large water distribution tray 2046, that is, the irrigation water flowing to the top of the large water distribution tray 2046 The irrigation water will be evenly distributed to the filter material filled in the filter tank 201 directly through the large water distribution pan 2046, thereby filtering the irrigation water through the filter material. When the irrigation water flow rate is relatively high, after it flows to the top of the large water distribution pan 2046, the water storage box 2045 and the water storage tank opened on the top of the large water distribution pan 2046 will be filled with irrigation water. At this time, the overall weight of the large water distribution pan 2046 will increase, thereby pressing and contracting the support spring 2047 at the bottom thereof, causing the large water distribution pan 2046 to slide downward as a whole, thereby canceling the clamping connection of the ball head 2043 to the bottom end of the water storage box 2045, so that the water accumulated in the water storage box 2045 can be The irrigation water in 045 flows to the top of the small water distribution pan 2044, and the irrigation water flowing to the top is evenly distributed to the top of the filter material through the small water distribution pan 2044. At this time, the small water distribution pan 2044 cooperates with the irrigation water distribution pan 2046 to reduce the instantaneous flow of the irrigation water flowing through the large water distribution pan 2046, so that the large water distribution pan 2046 can also evenly distribute the irrigation water, so as to avoid the situation that when the irrigation water flow is too large, the irrigation water will all rush to the large water distribution pan 2046 in an instant, resulting in uneven distribution of the irrigation water. When the irrigation water flow flowing to the top of the large water distribution pan 2046 is reduced, the support spring 2047 is forced to shrink. The rebound force generated when the water distribution tray 2046 is lifted up will prop up the large water distribution tray 2046 again, and when the large water distribution tray 2046 slides upward, it will drive the water storage box 2045 to move together, so that the ball head 2043 and the inner bottom end of the water storage box 2045 are re-connected together, so that the irrigation water cannot flow onto the small water distribution tray 2044. After the irrigation water is evenly spread on the filter material, the particulate matter contained in the irrigation water can be filtered out by the filter material, and the filtered irrigation water is collected by the water collector 205 and discharged from the inside of the filter tank 201 through the water outlet 206, and the filtered water is transported to the inside of the water storage barrel 301 through the connecting pipe.

The outer side of the outer wall of the threaded sleeves 3055 is rotatably connected to the extension sleeves 3056, and the extension sleeves 3056 can move the irrigation pipes 305 The amount of water discharged each time is controlled. The inner wall of the connecting barrel 3051 and the plurality of irrigation pipes 3054 are fixedly connected with groove pipes 3057 at positions symmetrical to each other. The groove pipes 3057 are used to support the clamping balls 3058. The clamping balls 3058 are slidably connected inside the plurality of groove pipes 3057. The clamping balls 3058 are used to seal the two ends of the groove pipes 3057. The inner centers of the plurality of irrigation pipes 3054 are rotatably connected with baffles 3059 through pins.

The irrigation water inside the water supply box 303 can enter the interior of the connecting barrel 3051 through the water replenishment holes, so that water can be replenished into the interior of the connecting barrel 3051 at any time.

[0050] In this embodiment, preferably, a counterweight block is processed on the inner bottom end of the baffle 3059 so that the baffle 3059 can always remain perpendicular to the ground. When the irrigation pipe 3054 is in a vertical state, the baffle 3059 is in a state perpendicular to the ground under the action of the counterweight block, and the irrigation water inside the connecting barrel 3051 can enter the interior of the irrigation pipe 3054.

[0051] In summary, after the filtering mechanism 2 filters the irrigation water and transports it to the water storage barrel 301 in the irrigation mechanism 3, the valve processed on the connecting pipe connected to the side of the water storage barrel 301 is closed to prevent the irrigation water in the water storage barrel 301 from flowing back into the filtering tank 201.

After the irrigation water enters the connecting barrel 3051, two of the multiple irrigation pipes 3054 evenly distributed on the outer wall of the connecting barrel 3051 are in the vertical direction. The baffle 3059 inside the irrigation pipe 3054 in the vertical state will also be in a vertical state. At this time, the baffle 3059 will not seal the irrigation pipe 3054, and the irrigation water will flow into the irrigation pipe 3054 in the vertical state, while the baffles 3059 inside the other two irrigation pipes 3054 in the horizontal state are still in the vertical state. At this time, the baffle 3059 will seal the irrigation pipe 3054 to prevent the irrigation water from entering the interior thereof. Similarly, when the two irrigation pipes 3054 are in the vertical state, the card ball 3058 inside the groove pipe 3057 corresponding to the position of the irrigation pipe 3054 at the bottom will be blocked by the buoyancy of the irrigation water. The ball 3058 is used to float on the top of the groove tube 3057, so that the irrigation water in the irrigation pipe 3054 at the bottom flows out from the inside, so that the corn plants can be irrigated. Similarly, the ball 3058 inside the groove tube 3057 corresponding to the position of the two irrigation pipes 3054 in a horizontal state will be pressed against the end of the groove tube 3057 close to the irrigation pipe 3054 under the action of water pressure, so that the irrigation pipe 3054 in a horizontal state can be sealed to prevent the irrigation water therein from flowing out. Similarly, in the process of pushing the support mechanism 1 to move, the walking wheel 103 will The connecting barrel 3051 is continuously driven to rotate, so that the irrigation pipe 3054 located around the outer wall of the connecting barrel 3051 will discharge the irrigation water inside the irrigation pipe 3054 in turn, so that the connecting barrel 3051 is driven to rotate as the walking wheel 103 moves, and the corn plants can be irrigated quantitatively. When it is necessary to adjust the amount of irrigation water for the corn plants each time, the threaded sleeve 3055 is rotated, and the threaded sleeve 3055 slides on the outer wall of the irrigation pipe 3054, which can drive the extension sleeve 3056 to extend from the outer wall of the irrigation pipe 3054, so that the water output of the irrigation pipe 3054 and the extension sleeve 3056 can be adjusted.

[0053] See also Figure 1-Figure 13As shown, the first embodiment and the second embodiment are combined to obtain the present embodiment. When it is necessary to irrigate the corn plants in the corn field, the irrigation water is first transported to the filter tank 201 in the filter mechanism 2 by a water pump. The irrigation water can be filtered through the operation of the filter mechanism 2 to prevent impurities in the water from clogging the irrigation mechanism 3. After the filter mechanism 2 completes the filtration of the irrigation water, the filtered irrigation water can be stored in the water storage barrel 301 in the irrigation mechanism 3. Through the operation of the quantitative drainage component 305, when the walking wheel 103 drives the connecting barrel 3051 to rotate, whenever there is an irrigation pipe 3054 in a vertical state, the irrigation water remaining in the irrigation pipe 3054 and the extension sleeve 3056 is discharged. Since the spacing between the plants will be increased during corn planting, the irrigation water in the extension sleeve 3056 will be discharged. Keep it the same, so when the movement distance when the roller drives the connecting barrel 3051 to rotate a quarter of a circle is exactly the same as the spacing between the corn plants, the quantitative irrigation of each corn plant can be completed. After the filter mechanism 2 has been used for a period of time, as the filtered suspended matter and impurities continue to accumulate in the filter material layer, the filter material in the filter tank 201 needs to be cleaned to ensure its filtering effect on the irrigation water. At this time, backwashing water is pumped into the water outlet 206 by a water pump, so as to reverse osmosis clean the filter material layer inside the filter tank 201, flush out the filtered pollutants, and discharge the polluted water generated after cleaning from the water inlet 202 opened at the top of the filter tank 201, so as to facilitate the cleaning of the filter mechanism 2, so that the filter mechanism 2 can always maintain a good filtering effect.
