Description

Technical Field

[0001] The present application relates to the field of irrigation technology, and in particular to a water-saving irrigation device. Background Art

[0002] Farmland irrigation refers to an agricultural production activity that artificially transports water to farmland through the construction and use of water conservancy facilities to replenish soil moisture, meet crop growth needs, improve agricultural production capacity and stabilize crop yields. Irrigation can effectively solve the problem of water deficit caused by insufficient precipitation, uneven distribution or in the dry season, help ensure sufficient water supply for crops, enhance crop drought resistance, and improve land utilization and crop yields.

[0003] In the process of farmland irrigation, water-saving irrigation devices are usually used to save water and control the irrigation process. For example, water-saving irrigation devices are installed on the canals used for farmland irrigation. Water-saving irrigation devices usually consist of the following parts: filtration system, pipeline system, sprinkler system and control system for controlling water supply. Water-saving irrigation devices can save water and reasonably irrigate the water in the canal. The filtration system usually uses a filter net, which is installed at the water inlet end of the pipeline system to filter impurities in the canal, making it difficult for impurities to enter the pipeline system and cause blockage of the pipeline.

[0004] In the above technology, since most of the water in the canal is naturally collected rainwater, it is inevitable that there will be impurities such as leaves and branches. The canal also inevitably contains mud washed away. Therefore, during the use of the water-saving irrigation device, although muddy water, leaves, branches and other impurities will not enter the pipeline system, they may clog the filter net and make the water delivery process difficult, so improvements are needed. Utility Model Content

[0005] In order to improve the problem of difficulty in water delivery caused by easy clogging of the filter net, the present application provides a water-saving irrigation device.

[0006] The present application provides a water-saving irrigation device, which adopts the following technical solution:

[0007] A water-saving irrigation device comprises an irrigation box, a filter screen is installed on the side of the irrigation box close to the water inlet end, the irrigation box and the filter screen are both installed in a water channel, and a cleaning mechanism for cleaning impurities on the filter screen is also installed on the irrigation box, and the cleaning mechanism is located on the side of the filter screen away from the water inlet end of the irrigation box.

[0008] By adopting the above technical solution, when the irrigation box is used for water-saving irrigation, the filter net will block impurities and garbage, reducing the impact of the garbage dump on the water-saving irrigation process. At this time, the garbage will gradually accumulate on the filter net, which may easily cause the filter net to be blocked. The cleaning mechanism can clean the mesh surface of the filter net and clean the silt and impurities in the filter holes of the filter net, so that the water delivery process can continue.

[0012] By adopting the above technical solution, when the power component provides power, the rotating shaft will drive the rotating roller to rotate, and the bristles can then clean the impurities on the surface of the filter screen to achieve the cleaning purpose.

[0013] Optionally, the power assembly includes a driving member mounted on the mounting plate, and an output end of the driving member is coaxially fixed to the rotating shaft.

[0014] By adopting the above technical solution, the driving member is opened, and the output end of the driving member drives the rotating shaft to rotate together, the rotating shaft drives the rotating roller to rotate, and the rotating roller drives the bristles to rotate, thereby removing impurities on the filter screen.

[0016] By adopting the above technical solution, the reciprocating motion component can drive the mounting plate to reciprocate along the layout direction of the filter screen, so that the bristles can clean most of the mesh surface of the filter screen, further reducing the possibility of the filter screen being blocked.

[0017] Optionally, the reciprocating motion assembly includes a power member, a bidirectional threaded screw, and a guide rod, the power member is installed on a water channel on one side of the irrigation box, and the bidirectional threaded screw and the guide rod are located on a side of the filter screen away from the water inlet end of the irrigation box;

[0018] The bidirectional threaded screw and the guide rod are arranged in parallel and are both rotatably installed on one side of the water inlet end of the irrigation box. The mounting plate is provided with threaded holes and guide holes corresponding to the bidirectional threaded screw and the guide rod, respectively. The bidirectional threaded screw is threadedly inserted into the threaded hole, the guide rod is inserted into the guide hole, and one end of the bidirectional threaded screw is coaxially fixed to the power member.

[0019] By adopting the above technical solution, the power part can drive the bidirectional threaded screw to rotate. Under the limiting action of the guide rod, the bidirectional threaded screw can drive the mounting plate to reciprocate along the layout direction of the filter screen. At this time, the bristles can clean most of the mesh surface of the filter screen.

[0020] Optionally, the filter screen can be detachably mounted on the irrigation box.

[0021] By adopting the above technical solution, the detachable filter screen can be replaced, making maintenance more convenient.

[0022] Optionally, a coarse filter screen for blocking large-volume impurities is further provided at one end of the cleaning mechanism away from the filter screen.

[0023] By adopting the above technical solution, the coarse filter can block large-volume impurities such as branches, preventing the branches from accumulating on the filter and affecting the cleaning process of the bristles.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When using the irrigation box for water-saving irrigation, the filter will block impurities and garbage, reducing the impact of the garbage pile on the water-saving irrigation process. At this time, the garbage will gradually accumulate on the filter, which is easy to cause the filter to be blocked.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-2 , further details of this application are given.

[0032] The embodiment of the present application discloses a water-saving irrigation device.

[0033] A water-saving irrigation device, referring to Figure 1 , including an irrigation box 1, a filter screen 11 is installed on the side of the irrigation box 1 close to the water inlet end, the filter screen 11 is detachably installed on the irrigation box 1, and a cleaning mechanism 2 for cleaning impurities on the filter screen 11 is also installed on the irrigation box 1. The cleaning mechanism 2 is located on the side of the filter screen 11 away from the water inlet end of the irrigation box 1, and a coarse filter screen 12 for blocking large-volume impurities is also provided on the end of the cleaning mechanism 2 away from the filter screen 11. The coarse filter screen 12 will not block fine impurities, but only block large-volume impurities, so it is difficult to get blocked.

[0034] Reference Figure 1 and Figure 2 The cleaning mechanism 2 includes a mounting plate 21, a brush assembly 22 and a power assembly 23. The brush assembly 22 can clean fine impurities on the filter screen 11, and the power assembly 23 provides power for the cleaning process of the brush assembly 22.

[0035] Specifically, the cleaning brush assembly 22 includes a rotating shaft, a rotating roller 221 and bristles 222. Figure 1 and Figure 2 The rotating shaft is rotatably installed on the mounting plate 21, and the rotating axis of the rotating shaft is parallel to the mesh surface of the filter screen 11. The rotating roller 221 is coaxially sleeved and fixed on the rotating shaft, and the rotating circumferential surface of the rotating roller 221 is directly opposite to the mesh surface of the filter screen 11. The bristles 222 are fixedly arranged on the outer peripheral wall of the rotating roller 221. When the rotating roller 221 rotates, the bristles 222 can clean the mesh holes or the mesh surface on the filter screen 11 and brush away impurities.

[0036] The power assembly 23 includes a driving member mounted on the mounting plate 21, and the output end of the driving member is coaxially fixed with the rotating shaft. In this embodiment, the driving member adopts a stepper motor. In other embodiments, the driving member may also adopt a reduction motor, a servo motor, etc.

[0037] Since the cleaning range of the bristles 222 is limited when the rotating roller 221 rotates, it is difficult to effectively clean most of the mesh surface of the filter screen 11. Therefore, a reciprocating motion component 3 is also provided on the water inlet side of the irrigation box 1 for driving the mounting plate 21 to reciprocate along the layout direction of the filter screen 11. The reciprocating motion component 3 is installed on the canal 4. The reciprocating motion of the rotating roller 221 can be realized through the reciprocating motion component 3, so that the bristles 222 can clean most of the mesh surface of the filter screen 11.

[0038] Specifically, the reciprocating motion assembly 3 includes a power member 31, a bidirectional threaded screw 32, and a guide rod 33. Figure 1 and Figure 2 The power member 31 is installed on the water channel 4. The power member 31 adopts a reduction motor. In other embodiments, the power member 31 can also adopt a stepping motor or a servo motor. The bidirectional threaded screw 32 and the guide rod 33 are located on the side of the filter screen 11 away from the water inlet end of the irrigation box 1;

[0039] The bidirectional threaded screw 32 and the guide rod 33 are arranged in parallel and are both rotatably installed on the water channel 4. The mounting plate 21 is provided with threaded holes and guide holes corresponding to the bidirectional threaded screw 32 and the guide rod 33 respectively. The bidirectional threaded screw 32 is threadedly inserted into the threaded hole, and the guide rod 33 is inserted into the guide hole, and one end of the bidirectional threaded screw 32 is coaxially fixed to the power member 31.

[0040] The implementation principle of a water-saving irrigation device in an embodiment of the present application is: turn on the reduction motor, the reduction motor drives the bidirectional threaded screw 32 to rotate, the bidirectional threaded screw 32 drives the mounting plate 21 to reciprocate along the layout direction of the filter screen 11, during the movement, the stepper motor on the mounting plate 21 will drive the rotating roller 221 to rotate, the rotating roller 221 drives the bristles 222 to clean the mesh surface and mesh holes of the filter screen 11, reducing the possibility of impurities clogging the filter screen 11, so that the water delivery process can be carried out more smoothly and stably.
