Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a water replenishing device for grain planting. Background Art

[0002] In the process of grain planting, it is necessary to replenish water in time according to the growth needs of grains. With the development of agricultural planting technology, the existing water replenishment operation has changed from wastewater methods such as flooding to the use of pipes or vehicles to irrigate and drip irrigate grains. This method is more water-saving and has a good replenishment effect. One existing water replenishment method is to use multiple long tubes to set up between the fields, and a number of nozzles are arranged on the long tubes. After the long tubes are connected to the water supply, the nozzles spray water to achieve water replenishment. When using this water replenishment method, because the irrigation water is usually not fully purified and contains more impurities, after long-term use, the spray holes on the nozzles are easily blocked due to the accumulation of impurities, and it is very inconvenient to clean the nozzles one by one in the later stage. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1

[0021] Reference Figure 1-4 A water replenishment device for grain planting includes a main body 1, on which a plurality of valve assemblies are arranged, and a nozzle 2 is connected to the water outlet end of each valve assembly, and an end cap 3 is fixed to the end of the nozzle 2 away from the main body 1, and a spray hole 4 is penetrated through the end cap 3, and a dredging rod 5 is arranged outside the end cap 3, and the dredging rod 5 is coaxially and telescopically installed in the spray hole 4, and the maximum diameter of the dredging rod 5 is the same as the diameter of the spray hole 4; a conical head 6 is coaxially fixed to the end of the dredging rod 5 facing the spray hole 4, and the tip of the conical head 6 is arranged toward the spray hole 4. By utilizing the conical head 6 on the rod body, the water flow impacting the front end of the rod body can be guided to the surroundings by the conical bucket, so that the sprayed water flow can achieve omnidirectional coverage spraying, thereby obtaining a better water replenishment effect. At the same time, the rod body uses the conical head 6 to move back and forth in the spray hole 4, so as to scrape off the impurities attached to the inner wall of the spray hole 4, and ensure the smooth flow of the spray hole 4.

[0022] The valve assembly includes a water pipe 7, a first guide pipe 8, and a valve core driving mechanism. The water pipe 7 and the first guide pipe 8 are arranged to intersect in a cross shape and are interconnected. A valve core 9 is coaxially and telescopically installed in the first guide pipe 8. The valve core 9 is cylindrical, and a through hole 10 corresponding to the water pipe 7 is opened on the side of the valve core 9. A valve core driving mechanism is also installed on the first guide pipe 8, and the valve core driving mechanism is used to drive the valve core 9 to make reciprocating telescopic movements in the first guide pipe 8. By setting the valve assembly, the movable valve core 9 is used to change the position of the through hole 10 aligned with the water pipe 7. When the through hole 10 is completely aligned with the water pipe 7, the water flow is the largest. When the through hole 10 and the water pipe 7 are gradually staggered, the water flow gradually decreases, so that the flow rate of the water flow entering the nozzle 2 can be controlled, so that the water pressure sprayed from the spray hole 4 can be changed, so that the pressure caused by the water flow impacting the dredging rod 5 can be changed, so that the dredging rod 5 can be extended and retracted under the condition of pressure change, thereby changing the distance between the conical head 6 at the front end of the dredging rod 5 and the spray hole 4. When the conical head 6 is close to the spray hole 4, the water flow sprayed from the spray hole 4 is guided to a distant place by the conical head 6. When the conical head 6 is far away from the spray hole 4, the water flow sprayed from the spray hole 4 is guided to a nearby place by the conical head 6, so that the coverage of the water flow can be further improved. A rubber sealing sleeve is sleeved on the valve core 9.

[0023] When the utility model is in use, the main pipe body 1 is set up in the farmland, and then the main pipe body 1 is connected to the water supply system. When the water supply system is working, water is injected into the main pipe body 1, and the water then enters multiple nozzles 2. The water entering the nozzles 2 will push the dredging rod 5 to overflow the spray hole 4, and then the water will be guided to the surroundings through the conical head 6 at the front end of the dredging rod 5 to achieve omnidirectional coverage spraying. After the water supply is stopped, the dredging rod 5 automatically resets and extends into the spray hole 4. During the process of the dredging rod 5 moving back and forth in the spray hole 4, the conical head 6 thereon will scrape off impurities on the inner wall of the spray hole 4, thereby ensuring that the spray hole 4 will not be blocked.

[0024] Example 2

[0025] Reference Figure 5 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the valve core driving mechanism includes a first magnetic member 13, a second magnetic member 12, and a second guide tube 11. The first magnetic member 13 is fixed at one end of the valve core 9, and the second guide tube 11 is fixed on the first guide tube 8 near one end of the first magnetic member 13. The second guide tube 11 is made of plastic. The second magnetic member 12 is coaxially and telescopically installed in the second guide tube 11. The second magnetic member 12 and the first magnetic member 13 attract each other, and a pull rope 14 is connected to the second magnetic member 12. By pulling the pull rope 14, the pull rope 14 drives the second magnetic member 12 to move back and forth in the second guide tube 11. When the second magnetic member 12 moves and approaches the first magnetic member 13, the magnetic attraction between the two will cause the first magnetic member to drive the valve core 9 to move toward the second magnetic member 12. When the second magnetic member 12 is away from the first magnetic member 13, the first magnetic member and the valve core 9 are automatically reset.

[0026] The second magnetic member 12 is provided with an insertion hole, and the pull rope 14 is inserted into the insertion hole. When the valve core driving mechanism is in use, all the pull ropes 14 can be connected in series, and then the pull ropes 14 at the head end or the tail end are connected to the driver, and the pull ropes 14 are pulled back and forth by the driver, so that the pull ropes 14 connected in series move synchronously, so that all the second magnetic members 12 can move synchronously.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
