Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation devices, in particular to a drip irrigation device for horticulture. Background Art

[0002] A drip irrigation device is an efficient irrigation system that directly delivers water and nutrients to the vicinity of plant roots through a pipeline system and drips them into the soil in a drip-by-drip manner. The advantages of the drip irrigation system include water conservation, fertilizer conservation, labor saving, which can increase the yield and quality of crops, reduce the application amount of water and fertilizer and labor costs at the same time. It can also effectively control soil humidity and temperature and reduce the occurrence of pests and diseases.

[0003] For horticultural plants, the main function is to beautify the environment, provide green space and increase visual beauty. However, most of the existing horticultural drip irrigation devices use a single water outlet for drip irrigation, and the drip irrigation positions are relatively concentrated, which is likely to cause the accumulation of salts in the soil. Especially when using drip irrigation in soil with high salt content, since the roots will grow concentratedly towards the wet area, it may limit the development of roots and affect the growth of plants, which will have a greater impact on the uniformity of horticultural plants. In addition, the existing drip irrigation devices usually use multiple pipes to control a single water outlet respectively, and control the overall water flow size at the total water inlet. During the actual drip irrigation process, the single water outlet drips water downward for irrigation. Regardless of the water flow size, the drip irrigation position of the single water outlet is the same, and when the water flow is large, it is easy to impact the soil and damage the growth environment of plants.

[0004] Therefore, the applicant provides a drip irrigation device for horticulture to solve the problems raised in the above background art. Content of the Utility Model

[0009] A further improvement of the technical solution of the utility model lies in that one side of the rotary valve is connected to the water pump, and the other side is connected to a rotary joint through a connecting pipe. A plurality of first interfaces are arranged on the rotary joint, and one end of the water pipe is connected to the first interface.

[0010] A further improvement of the technical solution of the present utility model lies in that: a circular current-limiting sheet is arranged inside the connecting pipe, and a plurality of current-limiting holes are opened on the current-limiting sheet. The sizes of the current-limiting holes at both ends of the current-limiting sheet along the diameter are equal, and the current-limiting holes on the current-limiting sheet decrease and then increase in sequence along the circumferential direction.

[0011] A further improvement of the technical solution of the present utility model lies in that: a strip-shaped notch is opened through the rotation valve for water flow. The length of the notch is equal to the diameter of the current-limiting sheet, and the width of the notch is greater than the diameter of the largest current-limiting hole.

[0012] A further improvement of the technical solution of the present utility model lies in that: the drip head assembly further includes a drip head female part and a drip head male part sleeved with each other.

Compared with the existing single-outlet downward dripping irrigation, no matter the size of the water flow, the dripping position of the single-outlet drip irrigation is the same, and the greater the water flow, the easier it is to impact the soil and damage the growth environment of plants. Since the water outlet direction of the utility model is obliquely upward, the water flow impact force will not directly act on the soil, so the growth environment of plants will not be damaged. In addition, the greater the water flow, the larger the drip irrigation range, which is beneficial for gardeners to carry out drip irrigation on plants targeted by controlling the rotary valve.

The drip head female part and the drip head male part of the drip irrigation device are sleeved with each other, which is beneficial to controlling the drip irrigation amount of each drip head assembly. Different gardening plants have different water requirements. Multiple water pipes can be flexibly adjusted according to the water requirements of different plants to achieve precise drip irrigation. Specifically, a second pipe sleeve is adaptively arranged in the center of the inner cavity of the drip head male part in a conical plug. The conical plug is of a conical structure. By controlling the sleeving degree of the drip head female part and the drip head male part, the blocking degree of the conical plug to the water flow is controlled, which is beneficial to realizing the precise drip irrigation of different types of gardening plants.

[0035] The following further explains the present utility model in combination with specific embodiments.

[0036] As Figure 1-7 shown, a kind of gardening drip irrigation device provided in this embodiment includes a bottom plate 1. A water pump 2 is arranged on the bottom plate 1. The water pump 2 is used for pumping water. The bottom of the water pump 2 is connected to a pumping pipeline through a pipe. One side of the water pump 2 is connected to a drip irrigation valve assembly 4 through a pipe. The drip irrigation valve assembly 4 is respectively connected to a drip head assembly 5 through a plurality of water pipes 3. A rotary valve 41 is arranged on the drip irrigation valve assembly 4 for controlling the size of the water flow in stages. A plurality of water outlets 511 are evenly opened on the drip head assembly 5. Each water outlet 511 is bent inward, for uniformly dripping irrigation on the roots of plants in a dispersed state. A plurality of water outlets 511 are evenly opened on the drip head assembly 5 of the drip irrigation device. The plurality of water outlets 511 discharge water together for drip irrigation, forming a surface coverage, which is beneficial to uniformly drip irrigation on the roots of plants in a dispersed state, and avoids the relatively concentrated drip irrigation position, resulting in the accumulation of salts in the soil. Each water outlet 511 is bent inward at an angle of 30° - 60°, so that the water outlet direction is along the upper oblique direction. Compared with the water outlet direction of downward drip irrigation, it is beneficial to make the water flow easier to spread outward and increase the area of the drip irrigation soil.

[0037] As Figure 1-4As shown in FIGS. 6 and 7, in this embodiment, one side of the rotary valve 41 is connected to the water pump 2 through a pipe, and the other side is connected to the adapter 43 through the connecting pipe 42. A plurality of first interfaces 44 are provided on the adapter 43, and one end of the water pipe 3 is connected to the first interface 44. A circular flow-limiting piece 421 is arranged in the connecting pipe 42, and a plurality of flow-limiting holes 422 are formed in the flow-limiting piece 421. The flow-limiting holes 422 at both ends of the flow-limiting piece 421 along the diameter are of equal size, and the flow-limiting holes 422 on the flow-limiting piece 421 decrease first and then increase in sequence along the circumferential direction. A strip-shaped notch 411 is formed through the rotary valve 41 for the water flow to pass through. The length of the notch 411 is equal to the diameter of the flow-limiting piece 421, and the width of the notch 411 is greater than the diameter of the largest flow-limiting hole 422. The rotary valve 41 of this drip irrigation device is beneficial to controlling the size of the water flow in stages. Specifically, the rotary valve 41 is connected to the connecting pipe 42. By rotating the rotary valve 41, the strip-shaped notch 411 is respectively connected to flow-limiting holes 422 of different sizes, so as to control the water flow passing through the rotary valve 41 in stages. The rotary valve 41 controls the size of the total water flow. By connecting multiple water pipes 3, the drip irrigation amount of multiple drip head assemblies 5 is controlled. Compared with the existing single-outlet downward dripping irrigation, regardless of the size of the water flow, the position of the single-outlet drip irrigation is the same, and the greater the water flow, the easier it is to impact the soil and damage the growth environment of plants. In the present utility model, since the water outlet direction of the water outlet 511 is obliquely upward, the water flow impact force will not directly act on the soil, so the growth environment of plants will not be damaged. In addition, the greater the water flow, the larger the drip irrigation range, which is beneficial for horticulturists to perform drip irrigation on plants targeted by controlling the rotary valve 41.

[0038] As Figure 1 , 5 -7, in this embodiment, the drip head assembly 5 further includes a drip head female part 51 and a drip head male part 52 which are sleeved with each other. A conical plug 512 is arranged at the center of the inner cavity of the drip head female part 51, and a first pipe sleeve 513 is arranged around the conical plug 512. A second pipe sleeve 521 is arranged at the center of the inner cavity of the drip head male part 52 to fit the conical plug 512. The bottom of the second pipe sleeve 521 is connected to the second interface 522, and the other end of the water pipe 3 is connected to the second interface 522. Conical anti-detachment structures are arranged at both the first interface 44 and the second interface 522. The drip head female part 51 and the drip head male part 52 of this drip irrigation device are sleeved with each other, which is beneficial to controlling the drip irrigation amount of each drip head assembly 5. Different horticultural plants have different water requirements, and multiple water pipes 3 can be flexibly adjusted according to the water requirements of different plants to achieve precise drip irrigation. Specifically, a second pipe sleeve 521 is arranged at the center of the inner cavity of the drip head male part 52 to fit the conical plug 512. The conical plug 512 is in a conical structure. By controlling the sleeving degree of the drip head female part 51 and the drip head male part 52, the blocking degree of the conical plug 512 to the water flow is controlled, which is beneficial to achieving precise drip irrigation for different types of horticultural plants.

[0039] As Figures 5-6As shown in the figure, in this embodiment, a plurality of reinforcing ribs 514 are vertically arranged on the outer sidewall of the drip head female part 51. On the one hand, it is beneficial to reinforce the drip head female part 51 to prevent the deformation of the drip head female part 51 caused by water pressure. On the other hand, it is beneficial to hold the drip head female part 51 and the drip head male part 52 during installation; a plurality of water guiding strips 523 are vertically arranged on the inner sidewall of the drip head male part 52, which is beneficial to reducing the circumferential rotation of the water flow in the drip head male part 52 and guiding the water flow vertically.

[0040] As Figures 5-6 shown in the figure, in this embodiment, fixing lugs 524 are symmetrically arranged on the outer sidewall of the drip head male part 52, and through holes are formed in the fixing lugs 524 for fixing the drip head assembly 5 to the ground or a bracket, preventing the drip irrigation device from shifting during operation and affecting the drip irrigation position.

[0041] The working principle of the technical solution provided by the present utility model during use is as follows:

[0042] Start the water pump 2. The water pump 2 pumps water from the bottom and successively passes through the rotary valve 41, the connecting pipe 42, the adapter 43, the first interface 44, and the water pipe 3 to reach the drip head assembly 5, and gushes out from the water outlet 511 of the drip head assembly 5 for drip irrigation. A plurality of first interfaces 44 are arranged on the adapter 43, and the plurality of first interfaces 44 are respectively connected to a plurality of water pipes 3 to simultaneously perform drip irrigation on multiple horticultural plants. A plurality of water outlets 511 are circumferentially and evenly formed at the top of each drip head female part 51, and the plurality of water outlets 511 jointly discharge water for drip irrigation, forming a planar coverage to achieve uniform drip irrigation of the roots of plants in a dispersed manner and avoid relatively concentrated drip irrigation positions; each water outlet 511 is bent inward at an angle of 30° - 60°, so that the water outlet direction is along the obliquely upward direction, and the water flow is more likely to spread outward, increasing the area of the drip-irrigated soil; the drip head female part 51 and the drip head male part 52 are sleeved with each other to control the drip irrigation amount of each drip head assembly 5. A second sleeve 521 is arranged at the center of the inner cavity of the drip head male part 52 to fit the conical plug 512. The conical plug 512 has a conical structure. By controlling the sleeving degree of the drip head female part 51 and the drip head male part 52, the blocking degree of the conical plug 512 to the water flow is controlled, thereby realizing precise drip irrigation for different types of horticultural plants.

[0043] A rotary valve 41 is provided on the drip irrigation valve assembly 4 for controlling the size of the water flow in stages. The rotary valve 41 is connected to a connecting pipe 42. A strip-shaped notch 411 is formed through the rotary valve 41. A circular current-limiting sheet 421 is arranged in the connecting pipe 42. A plurality of current-limiting holes 422 are formed in the current-limiting sheet 421. The current-limiting holes 422 at both ends of the current-limiting sheet 421 along the diameter are equal in size. The current-limiting holes 422 on the current-limiting sheet 421 decrease first and then increase in sequence along the circumferential direction. By rotating the rotary valve 41, the strip-shaped notch 411 is respectively connected to current-limiting holes 422 of different sizes, so as to control the water flow passing through the rotary valve 41 in stages. Since the water outlet direction of the water outlet 511 is obliquely upward, the larger the water flow, the larger the drip irrigation range. The horticulturist can perform drip irrigation on plants by controlling the rotary valve 41 targeted.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
