Description

Technical Field

[0001] The invention relates to the technical field of farmland irrigation, and in particular to a farmland water-saving irrigation system. Background Art

[0002] When planting crops on farmland, 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 must be carried out to make up for the lack of natural rainfall, so it is necessary to use a farmland water-saving irrigation system.

[0003] The reel sprinkler is an efficient and flexible sprinkler equipment, which is widely used in farmland irrigation, garden irrigation, greening spraying and other fields. It is mainly composed of sprinkler heads, sprinkler trays, water pumps, pipes, electronic control components, etc. It adopts rotating sprinkler head technology, and drives the sprinkler heads to spray 360 degrees in all directions through the rotation of the sprinkler tray. The working principle of the reel sprinkler is that when the sprinkler is running, the water pump delivers water pressure to the sprinkler heads and provides air at the same time, so that the water and air are mixed to form water mist. The sprinkler heads rotate under the drive of the sprinkler tray and spray the water mist on the area that needs irrigation.

[0004] With respect to the reel sprinkler in the prior art, the inventor believes that the following defects exist during use: the water pipe connected to the sprinkler head is gradually lowered from the sprinkler disc during use, and the surface of the water pipe connected to the sprinkler head is in contact with the ground during the process of dragging the sprinkler head to the spraying area. The surface of the water pipe is easily contaminated with a lot of silt and other debris. When the water pipe is directly reeled in, silt and other debris are likely to affect the reeling of the water pipe. Therefore, it is necessary to make design improvements to the relevant technology. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a farmland water-saving irrigation system.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a farmland water-saving irrigation system, including a movable base, a sprinkler disk installed on the top of the movable base, a water pipe wound on the sprinkler disk, and a nozzle connected to the water outlet end of the water pipe, a vertical plate is fixed on the top of the movable base, a cleaning block for cleaning the rolled-up water pipe is arranged on the vertical plate, and the cleaning block is conical on the side away from the sprinkler disk.

[0007] By adopting the above technical scheme, the movable base, the sprinkler disc, the water pipe and the sprinkler head are all conventional components in the reel sprinkler, and the structural composition and the use principle are similar to those of the reel sprinkler, and there is no need to elaborate on them. In the process of the sprinkler disc controlling the reeling of the water pipe, the inner wall of the cleaning block abuts against the outer wall of the water pipe, so as to scrape off the sludge and other debris attached to the outer wall of the water pipe, thereby avoiding the situation where the outer wall of the water pipe is contaminated by sludge and other debris or the reeling of the water pipe is affected.

[0008] Furthermore, a scraper is provided on the vertical plate, and the blade of the scraper abuts against the conical outer wall of the cleaning block. A lower driving assembly for driving the cleaning block to rotate is provided on the vertical plate, and the lower driving assembly includes a horizontal plate fixed on the vertical plate, a lower motor fixed to the bottom of the horizontal plate, a lower gear fixed to the output end of the lower motor, and an annular rack fixed to the side wall of the cleaning block close to the sprinkler disk and meshing with the lower gear, and the axis of the annular rack coincides with the axis of the cleaning block and the axis of the water pipe.

[0009] By adopting the above technical solution, the lower motor drives the lower gear to rotate after it starts working. Since the lower gear is meshed with the annular rack on the cleaning block, the cleaning block rotates. During the process of cleaning the sludge and other debris on the water pipe, the sludge and other debris are easily accumulated on the surface of the cleaning block. After the cleaning block rotates, the scraper scrapes off the sludge and other debris attached to the surface of the cleaning block, so that the cleaning block continues to play the role of cleaning the dirt on the outer wall of the water pipe.

[0010] Furthermore, the cleaning block is composed of two half-gyro structures of the same structure, and a bolt that is gap-matched with the half-gyro structure is provided through the upper half-gyro structure, and the lower end of the bolt is threadedly connected to the lower half-gyro structure, and an annular cavity is provided in the half-gyro structure, and a heating wire is fixed in the annular cavity.

[0011] By adopting the above technical solution, the heating wire emits heat after working, so that the temperature in the annular cavity increases, thereby increasing the temperature of the outer wall of the semi-gyro structure that constitutes the cleaning block, so that sludge and other debris can be dried quickly, and the effect of the scraper on scraping off the dried sludge and other debris is fully improved, thereby improving the cleaning effect.

[0012] Furthermore, an annular mounting groove is provided on the inner wall of the semi-gyroscope structure, a thermally poor conductor sleeve is attached to and fixed on the inner wall of the annular mounting groove, the thermally poor conductor sleeve is attached to the outer wall of the water pipe, an extension cavity connected to the annular cavity is provided in the semi-gyroscope structure, and an end of the thermally poor conductor sleeve away from the sprinkler disk is located on the side of the extension cavity close to the sprinkler disk.

[0013] By adopting the above technical solution, the thermally poor conductor sleeve is made of a material with poor thermal conductivity. The setting of the thermally poor conductor sleeve makes the temperature of the part where the cleaning block contacts the water pipe lower, and will not cause the temperature of the water pipe to rise rapidly and soften or even damage the water pipe, thereby playing a good protective role for the water pipe.

[0014] Furthermore, a small storage battery electrically connected to the heating wire is fixed on the thermally poor conductor sleeve.

[0015] By adopting the above technical solution, a small battery is used to power the heating wire, and the small battery can rotate synchronously with the thermally poor conductor sleeve and the semi-gyro structure, thereby avoiding the situation where the cable gets entangled during the rotation of the semi-gyro structure due to the heating wire being connected to an external power supply, thereby ensuring the normal operation of the heating wire.

[0016] Furthermore, the scraper passes through the vertical plate and slides with the vertical plate. A receiving groove is provided on the top of the scraper. An upper driving assembly for driving the scraper to slide is provided on the vertical plate. The upper driving assembly includes a fixed block fixed to the side of the vertical plate close to the sprinkler disk, an upper motor fixed on the fixed block, an upper gear fixed to the output end of the upper motor, and a plurality of latch teeth evenly fixed in the receiving groove and meshing with the upper gear.

[0017] By adopting the above technical solution, the upper motor drives the upper gear to rotate after it starts working. Since the upper gear is engaged with the teeth in the receiving groove at the top of the scraper, the scraper can move along the vertical plate so that the vertical plate can scrape off the dirt attached to the scraper, thereby keeping the scraper surface clean and the cleaning effect.

[0018] Furthermore, a storage box located below the cleaning block is fixed on the top of the movable base, and the storage box is located on the side of the vertical plate away from the sprinkler disk and is located close to the vertical plate. A main battery and a controller are also fixed on the top of the movable base, and the upper motor and the lower motor are electrically connected to the main battery and the controller.

[0019] By adopting the above technical solution, the storage box plays a good role in collecting the dropped objects generated in the process of cleaning the debris on the outer wall of the water pipe. The setting of the controller makes it convenient for the staff to control the operation of the upper motor and the lower motor in time.

[0020] Furthermore, the nozzle includes a connector connected to an end of the water pipe away from the sprinkler plate and an end cap threadedly connected to the connector, a plurality of water spray holes are evenly arranged on the end cap, and a plurality of anti-slip strips are evenly arranged on the outer wall of the end cap.

[0021] By adopting the above technical solution, the staff can unscrew the end cap and replace it with an end cap with different spray holes, which is convenient for the staff to replace the corresponding nozzle according to the irrigation needs of different crops, thereby enhancing the water-saving effect.

[0022] In summary, the present invention has the following beneficial effects: 1. The movable base, sprinkler tray, water pipe and sprinkler head of the present application are all conventional components of the reel sprinkler, and the structural composition and the use principle are similar to those of the reel sprinkler, and no need to elaborate here. In the process of the sprinkler tray controlling the reeling of the water pipe, the inner wall of the cleaning block abuts against the outer wall of the water pipe, so as to scrape off the sludge and other debris attached to the outer wall of the water pipe, thereby avoiding the situation where the outer wall of the water pipe is polluted by sludge and other debris or the reeling of the water pipe is affected; 2. In the present application, after the lower motor works, it drives the lower gear to rotate. Since the lower gear meshes with the annular rack on the cleaning block, the cleaning block rotates. In the process of cleaning the sludge and other debris on the water pipe, the sludge and other debris are easily accumulated on the surface of the cleaning block. After the cleaning block rotates, the scraper scrapes off the sludge and other debris attached to the surface of the cleaning block, so that the cleaning block continues to play the role of cleaning the dirt on the outer wall of the water pipe; 3. In the present application, the heating wire generates heat after operation, so that the temperature inside the annular cavity increases, thereby increasing the temperature of the outer wall of the semi-gyro structure constituting the cleaning block, so that sludge and other debris can be dried quickly, and the scraper can fully improve the effect of scraping off the dried sludge and other debris, thereby improving the cleaning effect.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0026] like Figure 1-4 As shown, the embodiment of the present application discloses a farmland water-saving irrigation system, including a movable base 1, a sprinkler disc 2 is installed on the top of the movable base 1, a water pipe 3 is wound on the sprinkler disc 2, and the water outlet end of the water pipe 3 is connected to a sprinkler head 4. The movable base 1, the sprinkler disc 2, the water pipe 3 and the sprinkler head 4 are all conventional components in a reel sprinkler. The structural composition and use principle (including the water supply principle and the water spraying principle) of each component are similar to those of the reel sprinkler, and there is no need to elaborate on them here.

[0027] A vertical plate 5 is fixed on the top of the movable base 1, and a cleaning block 6 for cleaning the rolled water pipe 3 is arranged on the vertical plate 5. The cleaning block 6 is conical on the side away from the sprinkler disc 2. The cleaning block 6 is composed of two semi-gyro structures 61 with the same structure. A bolt 611 with a clearance fit with the semi-gyro structure 61 is penetrated by the upper semi-gyro structure 61, and the lower end of the bolt 611 is threadedly connected to the lower semi-gyro structure 61.

[0028] In this embodiment, an annular cavity 612 is provided in the semi-gyro structure 61, and a heating wire 7 is fixed in the annular cavity 612. An annular mounting groove 613 is provided on the inner wall of the semi-gyro structure 61, and a thermally poor conductor sleeve 8 is attached to and fixed on the inner wall of the annular mounting groove 613, and the thermally poor conductor sleeve 8 is attached to the outer wall of the water pipe 3. An extension cavity 614 connected to the annular cavity 612 is provided in the semi-gyro structure 61, and one end of the thermally poor conductor sleeve 8 away from the sprinkler disk 2 is located on the side of the extension cavity 614 close to the sprinkler disk 2, and a small storage battery 81 electrically connected to the heating wire 7 is fixed on the thermally poor conductor sleeve 8.

[0029] In order to facilitate the cleaning of the sludge and other debris on the outer wall of the water pipe 3, a scraper 51 is provided on the vertical plate 5, and the blade of the scraper 51 abuts against the conical outer wall of the cleaning block 6. A lower driving assembly 9 for driving the cleaning block 6 to rotate is provided on the vertical plate 5, and the lower driving assembly 9 includes a horizontal plate 91 fixed on the vertical plate 5, a lower motor 92 fixed to the bottom of the horizontal plate 91, a lower gear 93 fixed to the output end of the lower motor 92, and a circular ring rack 94 fixed to the side wall of the cleaning block 6 close to the sprinkler plate 2 and meshing with the lower gear 93, and the axis of the circular ring rack 94 coincides with the axis of the cleaning block 6 and the axis of the water pipe 3.

[0030] When the sprinkler plate 2 controls the water pipe 3 to reel in, the inner wall of the cleaning block 6 abuts against the outer wall of the water pipe 3, thereby scraping off the sludge and other debris attached to the outer wall of the water pipe 3, thereby avoiding the situation where the sludge and other debris contaminate the outer wall of the water pipe 3 or affect the reeling of the water pipe 3. After the lower motor 92 works, it drives the lower gear 93 to rotate. Since the lower gear 93 meshes with the annular rack 94 on the cleaning block 6, the cleaning block 6 rotates. When the cleaning block 6 cleans the sludge and other debris on the water pipe 3, the sludge and other debris are easily accumulated on the surface of the cleaning block 6. After the cleaning block 6 rotates, the scraper 51 scrapes off the sludge and other debris attached to the surface of the cleaning block 6, so that the cleaning block 6 continues to play the role of cleaning the dirt on the outer wall of the water pipe 3. The heating wire 7 generates heat after operation, so that the temperature in the annular cavity 612 increases, thereby increasing the temperature of the outer wall of the semi-gyro structure 61 constituting the cleaning block 6, so that the sludge and other debris can be dried quickly, and the scraper 51 can fully improve the effect of scraping off the dried sludge and other debris, thereby improving the cleaning effect.

[0031] In order to ensure the use effect of the scraper 51, the scraper 51 passes through the vertical plate 5 and slides with the vertical plate 5. A receiving groove 511 is provided at the top of the scraper 51. The vertical plate 5 is provided with an upper driving assembly 10 for driving the scraper 51 to slide. The upper driving assembly 10 includes a fixed block 101 fixed to the side of the vertical plate 5 close to the sprinkler plate 2, an upper motor 102 fixed to the fixed block 101, an upper gear 103 fixed to the output end of the upper motor 102, and a plurality of latches 104 uniformly fixed in the receiving groove 511 and meshing with the upper gear 103. After the upper motor 102 works, it drives the upper gear 103 to rotate. Since the upper gear 103 meshes with the latches 104 in the receiving groove 511 at the top of the scraper 51, the scraper 51 can move along the vertical plate 5, so that the vertical plate 5 scrapes off the dirt attached to the scraper 51, and keeps the surface of the scraper 51 clean and the cleaning effect.

[0032] In order to facilitate the collection and cleaning of debris generated during the cleaning process of the cleaning block 6 cleaning the outer wall of the water pipe 3 and the scraper 51 itself, a storage box 11 located below the cleaning block 6 is fixed on the top of the movable base 1. The storage box 11 is located on the side of the vertical plate 5 away from the sprinkler plate 2 and is located near the vertical plate 5. The main battery 12 and the controller 13 are also fixed on the top of the movable base 1. The upper motor 102 and the lower motor 92 are electrically connected to the main battery 12 and the controller 13. The storage box 11 plays a good role in collecting the dropped objects generated during the cleaning process of the outer wall of the water pipe 3. The setting of the controller 13 is convenient for the staff to control the operation of the upper motor 102 and the lower motor 92 in a timely manner.

[0033] The nozzle 4 includes a connector 41 connected to one end of the water pipe 3 away from the sprinkler disk 2 and an end cap 42 threadedly connected to the connector 41. A plurality of water spray holes 421 are evenly arranged on the end cap 42, and a plurality of anti-slip strips 422 are evenly arranged on the outer wall of the end cap 42, so that the staff can unscrew the end cap 42 and replace it with an end cap 42 with a different water spray hole 421, so that the staff can replace the corresponding nozzle 4 according to the irrigation needs of different crops and enhance the water-saving effect.

[0034] The use principle of a farmland water-saving irrigation system in this embodiment is as follows: when the sprinkler plate 2 controls the water pipe 3 to reel in, the inner wall of the cleaning block 6 abuts against the outer wall of the water pipe 3, thereby scraping off the sludge and other debris attached to the outer wall of the water pipe 3, thereby avoiding the situation where the sludge and other debris contaminate the outer wall of the water pipe 3 or affect the reeling of the water pipe 3. After the lower motor 92 works, it drives the lower gear 93 to rotate. Since the lower gear 93 meshes with the annular rack 94 on the cleaning block 6, the cleaning block 6 rotates. In the process of cleaning the sludge and other debris on the water pipe 3, the sludge and other debris are easily accumulated on the surface of the cleaning block 6. After the cleaning block 6 rotates, the scraper 51 scrapes off the sludge and other debris attached to the surface of the cleaning block 6, so that the cleaning block 6 continues to play the role of cleaning the dirt on the outer wall of the water pipe 3. The heating wire 7 generates heat after operation, so that the temperature in the annular cavity 612 increases, thereby increasing the temperature of the outer wall of the semi-gyro structure 61 constituting the cleaning block 6, so that the sludge and other debris can be dried quickly, and the scraper 51 can fully improve the effect of scraping off the dried sludge and other debris, thereby improving the cleaning effect.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
