DETAILED DESCRIPTION

[0042] 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 the embodiments.

[0043] Example 1, reference Figure 1-4 , a sprinkler head for watering a ground, comprising a spherical tube 14.

[0044] A plurality of water outlets 15 are distributed in a circular array on the outer side of the spherical tube 14 .

[0045] Reference Figure 7 A water pipe 19 is vertically connected to the spherical tube 14, and is connected to the nozzle water supply tank 1 above through the water pipe 19.

[0046] A driving rotating assembly is also provided between the water delivery pipe 19 and the nozzle water supply tank 1 ; the driving rotating assembly includes a first bevel gear 2 , a second bevel gear 3 , a third bevel gear 4 and a driving motor 6 .

[0047] The driving motor 6 is installed on the outside of the nozzle water supply box 1 , and the third bevel gear 4 is installed at the end of the output shaft of the driving motor 6 .

[0048] The first bevel gear 2 is mounted on the upper end of the inner cylinder 7 .

[0049] The second bevel gear 3 is installed on the outside of the water pipe 19 .

[0050] The third bevel gear 4 meshes with the first bevel gear 2 and the second bevel gear 3 respectively.

[0051] The first bevel gear 2 and the second bevel gear 3 rotate in opposite directions, and the first bevel gear 2 is located above the second bevel gear 3 .

[0052] A plurality of support plates 13 are connected between the upper portion of the spherical tube 14 and the water delivery pipe 19 .

[0053] The water delivery pipe 19 inside the nozzle water supply box 1 is provided with a plurality of water inlets 5 .

[0054] The water delivery pipe 19 is rotatably arranged in the sprinkler water supply box 1, and the rotating water delivery pipe 19 and the spherical tube 14 spray water from the water outlet 15 to achieve watering.

[0055] The traditional way of watering plants is to spray them from above. This will cause some of the water to evaporate, and the water cannot reach the roots of the plants smoothly. At the same time, a large amount of water accumulates on the leaves, making it impossible for the leaves to photosynthesize.

[0056] To this end, the traditional sprinkler is improved by connecting the water pipe 19 arranged in the vertical direction to the spherical tube 14 at the lower end. At this time, the power switch of the drive motor 6 is turned on. After the power is turned on, the third bevel gear 4 is driven to rotate, and the kinetic energy is indirectly transferred to the water pipe 19 through the second bevel gear 3, so that the water pipe 19 drives the spherical tube 14 at the lower end to rotate together. At the same time, the water filling port of the sprinkler water supply tank 1 is connected to the water pump, and the water in the sprinkler water supply tank 1 passes through the water inlet 5 into the water pipe 19. The pressure provided by the pump body and the centrifugal force generated when the spherical tube 14 rotates will spray the water, so that the sprayed water column will be more concentrated. In this way, the sprinkler water supply tank 1 is fixed on the telescopic frame of the mobile machinery. The height of the sprinkler water supply tank 1 is adjusted by the telescopic frame on the mobile machinery, and the position height of the spherical tube 14 can be indirectly adjusted.

[0057] Example 2, reference Figure 3-4 The difference between this embodiment and embodiment 1 is that an outer cylinder 8 is installed at the bottom of the nozzle water supply box 1.

[0058] refer to Figure 8 A regulating component is arranged at the lower end of the outer side of the outer cylinder 8.

[0059] The regulating assembly includes a first connecting rod 9 , an elastic column 10 , a water retaining plate 11 , a through hole 12 and a second connecting rod 20 .

[0060] refer to Figure 6 Two first connecting rods 9 and two second connecting rods 20 are hinged on the outside of the outer cylinder 8 in a ring array, and adjacent first connecting rods 9 and second connecting rods 20 are vertically arranged.

[0061] The adjacent first connecting rods 9 and second connecting rods 20 are connected by elastic columns 10, a water baffle plate 11 is installed at the far end of the second connecting rod 20, and a plurality of through holes 12 are evenly opened on the water baffle plate 11, the first connecting rod 9 is fixed to the outside of the outer tube 8, and in the initial state, the first connecting rod 9 and the second connecting rod 20 are vertically arranged for the purpose of fixing the elastic column 10 on the adjacent first connecting rod 9 and the second connecting rod 20, and the function of the first connecting rod 9 is that when the external force outside the second connecting rod 20 is removed, the second connecting rod 20 can be restored to its initial state under the action of the tension of the elastic column 10.

[0062] When watering the seedlings, the water baffle 11 can shield part of the water column sprayed from the water outlet 15 .

[0063] Since the position of the spherical tube 14 can be adjusted to the height of the root system of the plant, the sprinkled water can directly act on the soil near the root system, reducing the chance of contact with the leaves.

[0064] In the actual watering process, mature plants and seedlings are often cross-planted, and mature plants and seedlings are distributed in a linear arrangement. At this time, mature plants require a larger amount of water, but once a large amount of water is directly poured on the seedlings, the root stability of the seedlings is poor, and facing the impact of large flow, it will cause necrosis of the seedlings.

[0065] To this end, the regulating component provided includes a first connecting rod 9, an elastic column 10, a water baffle 11, a through hole 12 and a second connecting rod 20. Since the second connecting rod 20 is on the line of plant planting, when the second connecting rod 20 contacts the mature plant, a force will be generated between the plant and the second connecting rod 20. Since the second connecting rod 20 and the outer tube 8 are hinged, the angle of the second connecting rod 20 is deflected. After the deflection, the water baffle 11 connected to the end of the second connecting rod 20 will rotate. At this time, the position of the water baffle 11 and the water outlet 15 on the outside of the spherical tube 14 do not coincide. The water sprinkled by the second connecting rod 20 will be directly sprinkled on the soil at the root position of the mature plant. When the external force between the plant and the second connecting rod 20 disappears, the water retaining plate 11 returns to its original position under the action of the elastic column 10. When the second connecting rod 20 encounters the seedlings, some of the seedlings are not high enough to contact with the second connecting rod 20. Although the slightly taller seedlings can contact with the second connecting rod 20, the seedlings have soft stems and leaves and cannot exert an external force sufficient to change the deflection of the second connecting rod 20. At this time, the water retaining plate 11 is in its original state, that is, the water retaining plate 11 is located at the position where the water outlet 15 sprinkles water. The water coming out of the water outlet 15 contacts the water baffle 11, and after the collision, the energy of the water column is reduced. A small amount of water passes through the through hole 12 and falls on the soil at the root position of the seedling plant, so as to water the roots of the seedling, and realize the automatic switching of the watering mode for mature plants and seedlings, so as to protect the seedlings. Since the water outlet 15 continuously sprinkles water outward, part of the water does not fall on the root position of the plant, but falls on the soil in the farther area of ​​the root of the plant, so as to wet the soil and increase the overall water content of the soil. After the water content of the soil is increased, it is convenient for the roots of the plants to irrigate the soil in the later stage. Secondly, when the spherical tube 14 moves to the position closest to the seedling, that is, the spherical tube 14 and the seedling are in the same vertical plane, the distance to the water outlet 15 on the same side of the seedling is the closest and the impact force is the strongest. At this time, the water column with the greatest impact force ejected from the water outlet 15 is blocked by the water baffle 11, so as to reduce the kinetic energy of the water column and protect the seedling from harm. When the position of the spherical tube 14 appears in front of or behind the seedling, due to the increase in the distance between the water outlet 15 and the seedling, the water column ejected from the water outlet 15 is in a parabolic state, and the impact force of the water column is not enough to pose a threat to the seedling.

[0066] Example 3, reference Figure 5 The difference between this embodiment and embodiment 1 and embodiment 2 is that an inner cylinder 7 is rotatably provided on the inner top of the nozzle water supply box 1, the inner cylinder 7 is located on the inner side of the water supply pipe 19, and the lower end of the inner cylinder 7 passes through the spherical tube 14 and extends to the lower side thereof.

[0067] An annular ring 22 is provided at the bottom of the spherical tube 14 , and multiple cutting components are provided on the outside of the annular ring 22 and at the bottom of the inner tube 7 .

[0068] The cutting assembly includes a long rope 16 , a square rod 17 and a water pipe 23 .

[0069] The square rods 17 are evenly connected to the inner cylinder 7 and the outside of the annular ring 22 .

[0070] The water pipe 23 is located inside the square rod 17 , one end of the long rope 16 is fixed inside the water pipe 23 , and the other end thereof extends to the outside of the water pipe 23 , and the water pipe 23 is connected to the inside of the inner tube 7 .

[0071] Since there are many weeds near the growing area of ​​the plants, the presence of weeds will rob the plants of water and nutrients.

[0072] To this end, during the watering process, it is necessary to deal with the weeds near the plants, and the third bevel gear 4 is used to drive the first bevel gear 2 and the second bevel gear 3 to achieve opposite rotation, so that the water pipe 19 and the inner cylinder 7 rotate in opposite directions. As a result, the annular ring 22 connected to the lower end of the spherical tube 14 rotates in opposite directions to the inner cylinder 7. At the same time, the square rod 17 installed on the inner cylinder 7 and the square rod 17 installed on the annular ring 22 have different rotation directions. At this time, the rotation directions of the long ropes 16 at different heights are also inconsistent. During the rapid rotation of the long rope 16, the safety distance between the end of the long rope 16 and the plant is adjusted. When the long rope 16 contacts the weeds, the cutting force generated will cut off the weeds. The long ropes 16 at different heights will cut the weeds into multiple sections in an instant, and the impact force generated will knock the cut weed sections away from the root position of the plant to prevent the weed sections from accumulating at the root position of the plant, so that the sprinkled water cannot pass through the accumulated weed sections to enter the soil.

[0073] Example 4, reference Fig. 9 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that a pin hole 21 is provided on the square rod 17, a fixing pin 18 is inserted into the inner side of the pin hole 21, and the pin hole 21 and the fixing pin 18 cooperate with each other to adjust the length of the long rope 16.

[0074] A cavity 24 is provided inside the water pipe 23 close to the inner tube 7 , and a sphere 25 is provided between the cavity 24 and the water pipe 23 , and the size of the sphere 25 matches the size of the inside of the water pipe 23 .

[0075] Since there is no specific standard for the spacing between plants between ridges in the field, the long rope 16 cannot cut the plants on both sides at the same time.

[0076] To this end, a fixing pin 18 for fixing the long rope 16 and a matching pin hole 21 are provided on the upper part of the square rod 17. When the length of the long rope 16 needs to be adjusted, part of the long rope 16 can be pulled out and then the long rope 16 can be fixed by the fixing pin 18. In this way, the length of the long rope 16 can be adjusted, which is suitable for weeding between ridges with different spacings.

[0077] In addition, the length of the square rod 17 is greater than the length of the long rope 16 exposed outside the square rod 17. This design is mainly to prevent the long rope 16 from getting tangled when rotating.

[0078] The working principle of the device is:

[0079] In the actual process of watering plants, the watering nozzle is usually set above the plants, because this can more conveniently cover a large area of ​​plants, but this way of watering will cause the leaves of mature plants to intercept water. Under the action of evaporation, the roots do not get too much water. This not only wastes water, but also when water is sprinkled on the leaves, it may affect the photosynthesis of the leaves, because the water will block sunlight from reaching the stomata of the leaves, and wet leaves are also more likely to attract diseases.

[0080] The traditional sprinkler is improved by connecting the water pipe 19 arranged in the vertical direction to the spherical tube 14 at the lower end. At this time, the power switch of the driving motor 6 is turned on. After the power is turned on, the third bevel gear 4 is driven to rotate, and the kinetic energy is indirectly transmitted to the water pipe 19 through the second bevel gear 3, so that the water pipe 19 drives the spherical tube 14 at the lower end to rotate together. At the same time, the water injection port of the sprinkler water supply tank 1 is connected to the water pump, and the water in the sprinkler water supply tank 1 enters the water pipe 19 through the water inlet 5. The pressure provided by the pump body and the centrifugal force generated when the spherical tube 14 rotates will spray the water, so that the sprayed water column will be more concentrated. The sprinkler water supply tank 1 is fixed on the mobile machinery. By adjusting the height of the sprinkler water supply tank 1, the position of the spherical tube 14 can be effectively adjusted to the position of the plant root system, and the sprinkled water can directly act on the soil near the root system, reducing the chance of contact with the blades.

[0081] In the actual watering process, mature plants and seedlings are often cross-planted, and mature plants and seedlings are distributed in a linear arrangement. At this time, mature plants require a larger amount of water, but once a large amount of water is directly poured on the seedlings, the root stability of the seedlings is poor, and facing the impact of large flow, it will cause necrosis of the seedlings.

[0082] To this end, the regulating component provided includes a first connecting rod 9, an elastic column 10, a water retaining plate 11, a through hole 12 and a second connecting rod 20. Since the second connecting rod 20 is on the line of plant planting, when the second connecting rod 20 contacts the mature plant, a force will be generated between the plant and the second connecting rod 20. Since the connection between the second connecting rod 20 and the outer cylinder 8 is hinged, the angle of the second connecting rod 20 is deflected. After the deflection, the water retaining plate 11 connected to the end of the second connecting rod 20 will rotate. At this time, the position of the water retaining plate 11 and the water outlet 15 on the outside of the spherical tube 14 do not coincide. The water spilled from the water outlet 15 will be directly sprinkled on the soil at the root position of the mature plant. When the external force between the plant and the second connecting rod 20 disappears, under the action of the elastic column 10, the water retaining plate 11 returns to its initial position; when the second connecting rod 20 encounters the seedlings, some of the seedlings are not high enough and cannot contact the second connecting rod 20. Although the slightly taller seedlings can contact the second connecting rod 20, due to the soft stems and leaves of the seedlings, it is impossible to apply an external force sufficient to change the deflection of the second connecting rod 20. At this time, the water baffle 11 is still in its initial state, that is, the water baffle 11 is located at the position where the water outlet 15 sprinkles water, and the water coming out of the water outlet 15 contacts the water baffle 11. After the collision, the energy of the water column is reduced, and a small amount of water passes through the through hole 12 and falls on the soil at the root position of the seedling plant, watering the roots of the seedlings, and realizing automatic switching of the watering mode for mature plants and seedlings, preventing the large flow of water column from killing the seedlings and protecting the seedlings.

[0083] Since there are many weeds near the growing area of ​​the plants, the presence of weeds will rob the plants of water and nutrients.

[0084] To this end, during the watering process, it is necessary to deal with the weeds near the plants, and the third bevel gear 4 is used to drive the first bevel gear 2 and the second bevel gear 3 to achieve opposite rotation, so that the water pipe 19 and the inner cylinder 7 rotate in opposite directions. As a result, the annular ring 22 connected to the lower end of the spherical tube 14 rotates in the opposite direction to the inner cylinder 7. At the same time, the square rod 17 installed on the inner cylinder 7 and the square rod 17 installed on the annular ring 22 have different rotation directions. At this time, the rotation directions of the long ropes 16 at different heights are also inconsistent. During the rapid rotation of the long rope 16, the safety distance between the end of the long rope 16 and the plant is adjusted. When the long rope 16 contacts the weeds, the cutting force generated will cut off the weeds. The long ropes 16 at different heights will cut the weeds into multiple sections in an instant, and the impact force generated will knock the cut weed sections away, and the weed sections are away from the root position of the plant to prevent the weed sections from accumulating at the root position of the plant, so that the sprinkled water cannot pass through the accumulated weed sections to enter the soil.

[0085] Since the long rope 16 is bound to be stained with mud during the process of cutting the weed segments, the cutting effect thereof is reduced.

[0086] To this end, a water pipe 23 is provided on the inner side of the square rod 17, and the water pipe 23 is interconnected with the interior of the inner cylinder 7. The interior of the inner cylinder 7 is filled with water. During the rapid rotation of the square rod 17, the centrifugal force generated causes the ball 25 inside the water pipe 23 to move toward the distal end. When it moves to the position of the cavity 24, due to the inclined setting of the cavity 24, the ball 25 will continue to move into the cavity 24 under the action of centrifugal force. Since the sizes of the ball 25 and the water pipe 23 match each other, once the ball 25 enters the inner side of the cavity 24, the water pipe 23 is opened, so that the water in the inner cylinder 7 can enter the water pipe 23 and soak the long rope 16, which can not only wash away the mud on the long rope 16 under the action of centrifugal force, but also increase the weight of the long rope 16 and improve the cutting effect. When the long rope 16 stops rotating, the ball 25 falls back into the water pipe 23 under the action of its own gravity, so that the water flow can be stopped.

[0087] Since there is no specific standard for the spacing between plants between ridges in the field, the long rope 16 cannot cut the plants on both sides at the same time.

[0088] To this end, a fixing pin 18 for fixing the long rope 16 and a matching pin hole 21 are provided on the upper part of the square rod 17. When the length of the long rope 16 needs to be adjusted, part of the long rope 16 can be pulled out and then the long rope 16 can be fixed by the fixing pin 18. In this way, the length of the long rope 16 can be adjusted, which is suitable for weeding between ridges with different spacings.

[0089] In addition, the length of the square rod 17 is greater than the length of the long rope 16 exposed outside the square rod 17. This design is mainly to prevent the long rope 16 from getting tangled when rotating.

[0090] The above are only preferred specific implementation modes 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 according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
