Description

Technical Field

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

[0002] A greenhouse is an agricultural facility that creates a relatively warm and controlled environment by covering it with plastic film or other transparent materials. It is mainly used to protect plants from growing in seasons or environments that are not suitable for growth and to maintain crop yields. Greenhouse irrigation is an irrigation activity for greenhouse crops. Since the greenhouse is a relatively closed production facility, natural rainfall cannot be used directly, and the water required by crops in the greenhouse is completely guaranteed by artificial irrigation measures. Therefore, greenhouse irrigation has its uniqueness and importance. The sprinkler irrigation device has a high degree of automation and can realize different operating modes such as forward operation, reverse operation, continuous sprinkler irrigation, and corresponding forward spraying according to the user's choice. The water is sprayed evenly, thereby promoting uniform growth of plants, consistent quality, improving the yield rate, and reducing losses.

[0003] Most existing irrigation systems are composed of sprinkler pipes and main water pipes. The main water pipes distribute the water required for irrigation to the sprinkler pipes, and then the sprinkler heads on the top of the sprinkler pipes are used for irrigation. The existing irrigation devices still have the following problems when in use: the connection between the existing sprinkler pipes and the main water pipes is mostly installed in an integrated manner, which limits the overall spraying range of the sprinkler system and makes it impossible to adjust according to actual conditions, making the irrigation system not very applicable.

[0004] Therefore, it is necessary to invent a greenhouse efficient water-saving irrigation system to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a greenhouse efficient water-saving irrigation system to solve the problem that the connection between the existing sprinkler pipe and the main water pipe proposed in the above background technology is mostly installed in an integrated manner, which results in the overall spraying range of the sprinkler system being limited and unable to be adjusted according to actual conditions, making the irrigation system not very applicable.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a greenhouse efficient water-saving irrigation system, comprising a main water pipe, a mounting pipe is installed in the interior of the main water pipe, the mounting pipe is connected to the main water pipe, a spray pipe is installed in the internal thread of the mounting pipe, and a spray head is installed on the top of the spray pipe, a water outlet is arranged in the interior of the mounting pipe, and a blocking block is installed in the interior of the water outlet, and further comprising:

[0007] Support assembly, the two sides of the mounting tube are provided with mounting notches, and the inside of the mounting notches is rotatably connected with an inclined plate through a cross bar, and the upper end of the inclined plate is fixedly connected with an arc plate, the inside of the arc plate is provided with a notch, and the inside of the notch is rotatably connected with an auxiliary roller, so as to support the spray pipe and prevent the spray pipe from tilting;

[0008] A movable support, wherein the inner wall of the main water pipe is fixedly connected with a second connecting rod, and the interior of the second connecting rod is movably connected with a first connecting rod via a spring, and the upper end of the first connecting rod is fixedly connected to the bottom of the block, supporting the stable movement of the block and the reset movement after the movement;

[0009] The ejection assembly, the inner wall of the spray pipe is fixedly connected with a fixing rod, and the bottom of the fixing rod is fixedly connected with a push rod, and the lower end of the push rod matches the limiting groove preset inside the block to drive the movement of the block.

[0010] Preferably, the number of the installation pipes is several, and the several installation pipes are linearly distributed inside the main water pipe at equal intervals;

[0011] An annular thread groove is arranged inside the installation tube, and the thread groove matches the thread reserved on the outer ring at the bottom of the spray pipe, so as to ensure that the spray pipe and the installation tube are matched and installed, and facilitate subsequent disassembly and replacement after installation.

[0012] Preferably, the outer ring of the cross bar is movably sleeved with a torsion spring, and one end of the torsion spring is fixedly connected to the inner wall of the mounting notch, and the other end of the torsion spring is fixedly connected to the inclined plate movably sleeved on the outer ring of the cross bar. The two sets of torsion springs apply force so that the two arc-shaped plates support the outside of the spray pipe.

[0013] Preferably, the auxiliary rollers are provided in a number, and the auxiliary rollers are arranged in a circular shape at equal angles inside the notch, and the outer wall of the auxiliary roller is in contact with the outer wall of the spray pipe and is rotatably connected. The auxiliary roller is rotatably connected with the spray pipe, which ensures that the spray pipe rotates smoothly when the spray pipe passes through the two arc plates and is threadedly connected with the mounting pipe;

[0014] The upper and lower ends of the roller shaft plugged into the inner ring of the auxiliary roller are respectively rotatably connected to the columnar grooves preset inside the arc plate, and the columnar grooves are communicated with the notches to ensure smooth rotation of the auxiliary roller.

[0015] Preferably, the blocking block is in a truncated cone shape, and the outer wall of the blocking block is in contact with the inner wall of the water outlet to achieve a sliding connection.

In this way, the water source inside the main water pipe is sprayed out through the spray head connected to the top of the spray pipe, and the crops inside the greenhouse are sprayed for irrigation. When the knob of the spray pipe is removed, the ejector rod provided inside the spray pipe moves in time and gradually leaves the preset limiting groove inside the block. At this time, the block is ejected and re-matched with the water outlet under the condition of spring reset movement. In this way, the spray pipe can be installed without cutting off the overall water source.

[0020] 2. When twisting and installing the sprinkler pipe, the ejector rod inside the sprinkler pipe will drop farther as the number of turns of the knob sprinkler pipe increases. This allows the water flow inside the sprinkler pipe to be adjusted in time by controlling the gap between the block and the water outlet, thereby controlling the spraying range of the sprinkler head and facilitating debugging and installation according to actual conditions.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The present invention provides Figure 1-5 The greenhouse efficient water-saving irrigation system shown in the figure comprises a main water pipe 1, a mounting pipe 2 is installed in the main water pipe 1, the mounting pipe 2 is connected to the main water pipe 1, a spray pipe 3 is installed in the internal thread of the mounting pipe 2, and a spray head 4 is installed on the top of the spray pipe 3, a water outlet 8 is arranged in the mounting pipe 2, and a blocking block 7 is installed in the water outlet 8, and further comprises:

[0031] The support assembly 6 is provided with mounting notches 601 on both sides of the mounting tube 2, and the inside of the mounting notches 601 is rotatably connected to an inclined plate 603 through a cross bar 602, and the upper end of the inclined plate 603 is fixedly connected to an arc plate 604, and a notch 606 is provided inside the arc plate 604, and the inside of the notch 606 is rotatably connected to an auxiliary roller 605, which supports the spray pipe 3 to prevent the spray pipe 3 from tilting and affecting the subsequent use of the spray pipe 3;

[0032] The movable support member 9 is fixedly connected to the inner wall of the main water pipe 1 with a second connecting rod 902, and the interior of the second connecting rod 902 is movably connected to a first connecting rod 901 through a spring 905, and the upper end of the first connecting rod 901 is fixedly connected to the bottom of the block 7. The two connecting rods support the stable movement of the block 7 and the reset movement after the movement, so as to facilitate the control of whether the water source passes through the installation pipe 2;

[0033] The ejector assembly 10, the inner wall of the spray pipe 3 is fixedly connected with a fixing rod 101, and the bottom of the fixing rod 101 is fixedly connected with a push rod 102, and the lower end of the push rod 102 matches with a preset limiting groove 103 inside the block 7, driving the movement of the block 7, so that the block 7 moves, and a gap can be formed between the block 7 and the water outlet 8, so that water source enters the interior of the spray pipe 3 through the gap between the block 7 and the water outlet 8 and is sprayed out by the sprinkler head 4 for irrigation.

[0034] There are a plurality of installation pipes 2, and the plurality of installation pipes 2 are linearly distributed inside the main water pipe 1 at equal intervals, so that there are more options for the installation of the spray pipes 3, and it is also convenient to select the spacing size and number of the installation spray pipes 3 according to actual conditions, so as to ensure that the irrigation device is more convenient when in use;

[0035] An annular threaded groove 5 is provided inside the mounting tube 2, and the threaded groove 5 matches the thread reserved on the outer ring at the bottom of the spray tube 3, ensuring that the spray tube 3 and the mounting tube 2 are matched and installed, and are convenient for subsequent disassembly and replacement after installation. The threaded connection has self-locking properties, making the matching installation of the spray tube 3 and the mounting tube 2 more secure.

[0036] The outer ring of the cross bar 602 is movably sleeved with a torsion spring, and one end of the torsion spring is fixedly connected to the inner wall of the mounting notch 601, and the other end of the torsion spring is fixedly connected to the inclined plate 603 movably sleeved on the outer ring of the cross bar 602. The two sets of torsion springs apply force so that the two arc plates 604 support the outside of the spray pipe 3, ensuring a better use effect of the spray pipe 3.

[0037] A plurality of auxiliary rollers 605 are provided, and the plurality of auxiliary rollers 605 are dispersedly arranged in a ring shape at equal angles inside the notch 606, and the outer wall of the auxiliary roller 605 is in contact with the outer wall of the spray pipe 3 to realize rotational connection, and the auxiliary roller 605 is rotationally connected with the spray pipe 3, which ensures that when the spray pipe 3 passes through the two arc plates 604 and realizes threaded connection installation with the installation pipe 2, the spray pipe 3 rotates smoothly;

[0038] The upper and lower ends of the roller shaft inserted into the inner ring of the auxiliary roller 605 are rotatably connected to the columnar groove 607 preset inside the arc plate 604 respectively, and the columnar groove 607 is connected to the notch 606 to ensure the smooth rotation of the auxiliary roller 605.

[0039] The blocking block 7 is in a truncated cone shape, and the outer wall of the blocking block 7 is in contact with the inner wall of the water outlet 8 to realize a sliding connection. The matching connection between the blocking block 7 and the water outlet 8 facilitates the subsequent installation of the spray pipe 3 to synchronously drive the movement of the blocking block 7. When the blocking block 7 moves downward, a gap will appear between the water outlet 8 which is also in a truncated cone shape.

[0040] Two protrusions 904 are fixedly connected to the two side walls of the lower end of the connecting rod 1 901, and the outer walls of the connecting rod 1 901 and the protrusions 904 are in contact with the inner walls of the movable groove 903 preset inside the connecting rod 2 902 to achieve a sliding connection, thereby ensuring the stability of the movement of the connecting rod 1 901 after the blocking block 7 is subjected to force, and further ensuring the stability of the downward movement of the blocking block 7.

[0041] The upper and lower ends of the spring 905 are respectively fixedly connected to the lower end of the connecting rod 1 901 and the inner wall of the movable groove 903 preset inside the connecting rod 2 902, so as to facilitate the subsequent movement of the spring 905 to drive the block 7 to move when it is subjected to force and the subsequent reset movement, and to facilitate the matching and separation of the block 7 with the water outlet 8, thereby controlling the water inlet of the installation pipe 2.

[0042] Working principle: When using a greenhouse efficient water-saving irrigation system, first, when it is necessary to install the spray pipe 3 and the mounting pipe 2, the outer wall of the lower end of the spray pipe 3 is installed with the preset thread groove 5 in the mounting pipe 2 by knob installation, and the thread of the outer circle of the bottom of the spray pipe 3 is threadedly connected with the preset thread groove 5 in the mounting pipe 2. The spray pipe 3 and the mounting pipe 2 are installed with the knob. When the spray pipe 3 and the mounting pipe 2 are installed with the knob, the height position of the lower end of the spray pipe 3 changes, and the spray pipe 3 as a whole moves downward while rotating. The top rod 102 set in the spray pipe 3 is synchronously lowered to support the upper end of the block 7 during the process of installing the knob of the spray pipe 3 and the mounting pipe 2, so that a gap appears between the downward movement of the block 7 and the water outlet 8 set in the mounting pipe 2 (refer to Figure 4 ), so that the water source inside the main water pipe 1 enters the spray pipe 3 through the water outlet 8 set inside the installation pipe 2 and the gap between the block 7, and is sprayed out through the spray head 4 connected to the top of the spray pipe 3 to perform spray irrigation on the crops inside the greenhouse. The spray irrigation has a large irrigation range and a relatively uniform irrigation water volume. At the same time, after the spray pipe 3 is installed by the knob, the torsion spring on the outer ring of the cross bar 602 pushes the arc plate 604 to support the spray pipe 3, ensuring that the use effect of the spray pipe 3 is better. At the same time, the outer wall of the auxiliary roller 605 rotatably connected in the notch 606 inside the arc plate 604 contacts the outer wall of the spray pipe 3. In this way, when the spray pipe 3 is twisted to install, the spray pipe 3 and the arc plate 604 are rotatably connected, ensuring that the spray pipe 3 is smoothly installed in rotation, and at the same time, the outside also has good support for the spray pipe 3;

[0043] When the knob of the spray pipe 3 is subsequently removed, the ejector rod 102 provided inside the spray pipe 3 is moved in a timely manner to gradually leave the preset limiting groove 103 inside the block 7. There is no gravity acting on the top of the block 7. At this time, the block 7 is ejected and re-matched with the water outlet 8 inside the installation pipe 2 when the spring 905 performs a reset movement. In this way, the spray pipe 3 can be installed without cutting off the overall water source. In this way, the spray pipe 3 can be added or removed during the use of the entire spray system.

[0044] When the spray pipe 3 is twisted and installed, the push rod 102 inside the spray pipe 3 drops farther as the number of turns of the knob of the spray pipe 3 increases, thereby supporting the block 7 and making the gap between the block 7 and the water outlet 8 larger and larger. In this way, the water flow inside the spray pipe 3 can be adjusted in time by controlling the gap between the block 7 and the water outlet 8, thereby controlling the spray range of the spray head 4. The threaded connection between the spray pipe 3 and the installation pipe 2 is self-locking, so that the angle position of the spray pipe 3 with the installation pipe 2 can be autonomously limited after the knob of the spray pipe 3 is turned an appropriate number of times, without the need to add limiting parts from the outside, which makes the operation simple and convenient.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
