Description

Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, in particular to a farmland water conservancy irrigation device. Background Art

[0002] In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation is necessary to make up for the lack of natural rainfall.

[0003] Different types of crops or crops in different growth periods require different amounts of water. Traditional farmland irrigation basically relies on water pumps and water pipes. The water pump draws water into the water pipes, and then irrigates through the water pipes. This irrigation method is difficult to control the amount of water sprayed, and cannot be adjusted accordingly according to the actual amount of water required for irrigation of crops, so it is less practical. Utility Model Content

[0004] (I) The problem to be solved by the utility model is that the traditional irrigation device cannot adjust the amount of water sprayed according to the amount of water required by the crops.

[0005] (II) Technical solution

[0028] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a farmland water conservancy irrigation device, including a main pipeline 1, a water pump 3 and a first riser 4;

[0030] A baffle 8 is fixedly connected to the top of the first riser 4;

[0031] The main pipeline 1 is connected with a branch pipe 2, the water inlet end of the water pump 3 is connected to the branch pipe 2, and the water outlet end is connected to the first riser 4;

[0032] A second riser 5 is disposed inside the first riser 4. A plurality of first through holes 401 are evenly and annularly formed on the first riser 4. A plurality of second through holes 501 are evenly and annularly formed on the second riser 5. Atomizing nozzles 7 are disposed directly below the plurality of first through holes 401. The atomizing nozzles 7 are connected to the first riser 4.

[0033] The axis of the first riser 4 coincides with the axis of the second riser 5 , the length of the first riser 4 is greater than the length of the second riser 5 , and a driving assembly 6 for driving the second riser 5 to move up and down is provided on the top of the second riser 5 .

[0034] Specifically, water flows from the main pipe 1 into the branch pipe 2, and is sent into the first riser 4 by the water pump 3. The driving component 6 drives the second riser 5 to move up and down, changing the overlapping area of ​​the first through hole 401 and the second through hole 501. The larger the overlapping area of ​​the first through hole 401 and the second through hole 501, the larger the water flow, which can irrigate crops requiring more water. When the overlapping area is small, the water flow spraying amount is small, which can irrigate crops requiring less water. When the crops requiring water require less water, the second riser 5 is continued to be moved, so that the multiple second through holes 501 opened on the second riser 5 overlap with the atomizing nozzle 7, and the water flow sprayed from the atomizing nozzle 7 can irrigate crops requiring less water. That is, the amount of water flow spraying can be adjusted according to the water required by different types of crops or crops at different times, and the practicability is high.

[0035] One end of the main pipeline 1 is blocked, and the other end is connected to a faucet for water supply. A booster pump is arranged at the end of the main pipeline 1 close to the faucet.

[0036] like Figure 2 and Figure 3 As shown, preferably, the driving assembly 6 includes a driving motor 601, a limiting column 604 and a mounting plate 605, and the output end of the driving motor 601 passes through the baffle 8 and is fixedly connected with a screw rod 602, and the screw rod 602 is screwed to the second vertical pipe 5 through a connecting block 603;

[0037] The limiting column 604 is slidably connected to the connecting block 603, and the limiting column 604 is fixedly connected to the baffle 8. The fixed end of the driving motor 601 is fixedly connected to the outer wall of the first vertical pipe 4 through the concave plate 607, wherein the baffle 8 is provided with a fifth through hole, and the radius of the fifth through hole is adapted to the radius of the screw 602.

[0038] The working principle of the driving assembly 6 is as follows: the driving motor 601 rotates, and the driving motor 601 penetrates the baffle 8 to drive the screw 602 fixedly connected thereto to rotate, and the connecting block 603 threadedly connected to the screw 602 moves up and down under the dual action of the limiting column 604 and the screw 602, thereby driving the second vertical pipe 5 fixedly connected to the connecting block 603 to move up and down.

[0039] Optionally, the driving assembly 6 includes an electric push rod and a mesh plate, the fixed end of the electric push rod is fixedly connected to the baffle 8, the pushing end of the electric push rod passes through the baffle 8 and is fixedly connected to the mesh plate, the mesh plate is fixedly connected to the second vertical pipe 5, the radius of the mesh plate is adapted to the radius of the second vertical pipe 5, and the second vertical pipe 5 is driven up and down by the electric push rod.

[0040] Furthermore, the use of electric push rods as actuators can not only reduce the air source devices and auxiliary equipment required by pneumatic actuators, but also reduce the weight of the actuators. Since pneumatic actuators require a certain air pressure during the entire control operation process, the air consumption is relatively large, and the use of electric push rods as actuators requires power supply when changing the control opening, and no power supply is required when the required opening is reached. Therefore, from the perspective of energy saving, electric push rods have obvious energy-saving advantages over pneumatic actuators, so electric push rods can be used as the execution structure.

[0041] It should be noted that the axis of the first riser 4 is perpendicular to the axis of the branch pipe 2 , and the axis of the first riser 4 is perpendicular to the horizontal plane.

[0042] Among them, the distance from the first through hole 401 to the atomizing nozzle 7 is smaller than the diameter of the second through hole 501. Preferably, the radius of the first through hole 401 is equal to the radius of the second through hole 501. Optionally, the radius of the first through hole 401 is smaller than the radius of the second through hole 501 by 0.1-0.5 mm.

[0043] Furthermore, a mounting plate 605 is fixedly connected to the bottom of the first vertical pipe 4 , the limiting column 604 is fixedly connected to the mounting plate 605 , the screw rod 602 is movably connected to the limiting column 604 , and a plurality of third through holes 606 are opened on the mounting plate 605 .

[0044] It should be noted that the installation of the mounting plate 605 can support and fix the limiting column 604, so that the second vertical pipe 5 can move up and down more smoothly. The third through hole 606 is provided to allow water to pass smoothly.

[0045] A bracket 9 for supporting the first riser 4 is installed on the first riser 4. Preferably, each leg of the bracket 9 is a telescopic rod with adjustable length, and a conical pile is installed at the bottom of the leg, which can be inserted into the ground to make the bracket 9 more stable. It should be noted that the setting of the bracket 9 can play a supporting role for the first riser 4.

[0046] Optionally, the legs of the bracket 9 have a fixed length, and the bottom surface of each leg is on the same horizontal plane.

[0047] In this embodiment, the first through hole 401, the second through hole 501 and the atomizing nozzle 7 are all arranged in six, two rows in total, three in each row, and the distance between the two first through holes 401, the distance between the two second through holes 501 and the distance between the two atomizing nozzles 7 in the vertical direction are all the same;

[0048] Among them, the row of first through holes 401 away from branch pipe 2 is row A1, and the row close to branch pipe 2 is row A2, the row of second through holes 501 away from branch pipe 2 is row B1, and the row close to branch pipe 2 is row B2, the row of atomizing nozzles 7 away from branch pipe 2 is row C1, and the row close to branch pipe 2 is row C2, and they are evenly arranged in a ring around the axis of the first vertical pipe 4;

[0049] The irrigation device can also select whether the water flow is sprayed from the first through hole 401 of row A1 or from the first through hole 401 of row A2 (i.e., select the height of the water flow spraying). It should be noted here that a valve is provided on the atomizing nozzle 7. When it is necessary to control the height of the water flow, the atomizing nozzle 7 is not used. The specific situation is as follows:

[0050] Case 1: The driving assembly 6 drives the second vertical pipe 5 to move downward until the B1 row is lower than the A1 row (i.e., the B2 row is lower than the A2 row), so that the water flows out through the first through holes 401 of the A1 row on the first vertical pipe 4, blocking the first through holes 401 of the A2 row. On this basis, the second vertical pipe 5 can be slightly moved up and down to change the overlap area of ​​the first through holes 401 of the A1 row and the second through holes 501 of the B1 row, thereby adjusting the amount of water flow to be sprayed out;

[0051] Case 2: The driving assembly 6 drives the second riser 5 to move upward until the B1 row is higher than the A1 row (i.e., the B2 row is higher than the A2 row), so that the water flows out through the first through holes 401 of the A2 row on the first riser 4, and blocks the first through holes 401 of the A1 row. On this basis, the second riser 5 can be slightly moved up and down to change the overlapping area of ​​the first through holes 401 of the A1 row and the second through holes 501 of the B1 row, so as to adjust the amount of water flow.

[0052] Specifically, in this embodiment, the irrigation device further includes a remote controller, and the driving motor 601, the water pump 3 and the valve on the atomizing nozzle 7 are all electrically connected to the remote controller.
