Description

A combined dual-branch pipe fixed-moving dual-purpose sprinkler irrigation system

technical field

The invention relates to a sprinkler micro-irrigation system in the fields of farmland, gardens, water delivery, etc., in particular to a combined double-branch pipe fixed-moving dual-purpose sprinkler irrigation system with variable nozzle spacing.

Background technique

Pipeline sprinkler irrigation systems are divided into three categories: fixed, semi-fixed and mobile. The fixed system has a large amount of pipes and high investment, and is suitable for perennial economic crop irrigation; semi-fixed and mobile sprinkler irrigation systems are widely used in field crops, and most of the moving parts are manually moved. Light and small mobile sprinkler irrigation units are widely used in my country because of their low cost, flexible maneuverability, and strong adaptability to terrain and crops. However, with the transfer of rural labor force in recent years, the gradual development of moderate-scale operations, the changing of crop seasons, and the need for emergency drought relief, the disadvantages of large mobile labor requirements for light and small sprinkler irrigation machines have become increasingly prominent.

Mobile sprinkler irrigation systems generally adopt a "one"-shaped, Feng-shaped or comb-shaped arrangement. The two sides of the nozzle standpipe are directly connected to the pipeline, which makes it difficult to adjust the distance between the nozzles in time according to field factors such as outdoor wind speed, wind direction, and crop row spacing. It is also difficult for the nozzle to adapt to irregular land or corners. In hilly areas or intercropping of crops, the working pressure of nozzles in different plots is different or the irrigation quota of crops is different, so different nozzles need to be used, and flexible configuration is required; for the irrigation area of about 50 mu, and multiple irrigations are required in the same irrigation season In some occasions, the pipe network should be fixed during the irrigation season, and the pipes should be removed when the crops are harvested or when the stubble is changed. If a fully mobile irrigation unit is used, the mobile operation will take a long time.

The installation and movement of light and small mobile sprinkler irrigation units is time-consuming and labor-intensive, and the distance between nozzles is difficult to adjust according to field application conditions. In hilly areas or intercropping of crops, nozzles are required to be flexibly configured, and the fixed moving time of pipelines is not easy to allocate.

After searching, there is no application patent for the combined double-branch pipe fixed-moving dual-purpose sprinkler irrigation system at present.

Contents of the invention

The object of the present invention is to provide a combined dual-pipe fixed-moving dual-purpose sprinkler irrigation system with convenient installation, movement and fixation, adjustable nozzle spacing, flexible pipeline combination form, and strong adaptability to terrain and crops.

The present invention achieves the above object through the following technical solutions: a combined double-branch pipe fixed-moving dual-purpose sprinkler irrigation system, including a water pump unit, a main pipe, a branch control valve, a sub-main pipe, several sets of double-branch pipe nozzle combinations, a combination of four-way and gag. The double-branch nozzle combination is composed of symmetrically arranged double-branch pipes and two nozzles. The outlet of the water pump unit is connected to the main pipe, and the branch control valve is set at the inlet of the sub-main pipe. It is connected with the sub-dry pipe through a combination four-way. The main pipe, branch pipe and double branch pipe adopt hard plastic pipe or plastic-coated hose.

A branch pipe is combined with several groups of double-branch nozzles connected to the pipe to form a control unit, and its opening and closing is controlled by a branch control valve. The combination four-way is composed of two three-way joints staggered through quick connectors, in which the upper three-way is connected to the double-branch pipe, and the lower three-way is connected to the branch pipe, which is easy to install and disassemble; when a group of double-branch nozzles in the local corner is not used , Remove the upper tee and seal it with a plug. The irrigation area of a control unit in the light and small sprinkler irrigation unit is not large, and it is generally not necessary to control each group of double-branch nozzle combinations. Therefore, for special occasions, plugs are used instead of valves to reduce costs.

The setting of the combination four-way can make the combination of double-branch nozzles be installed, disassembled and moved in groups; the combination of double-branch nozzles can be combined indoors as a set, and then installed and fixed in the field. The nozzle is connected to the branch pipe through one side, and then connected to the branch pipe, which can make the installation and disassembly of the nozzle more labor-saving; this advantage is more obvious in the micro-sprinkling or micro-irrigation system where the branch pipe and the capillary pipe are connected by plugging and unplugging; all in the system Only one side of the nozzle is connected to the pipeline. If the branch pipe is made of plastic-coated hose, the nozzle can be moved freely within a certain range. It is placed at the most needed position on the plot like a drop arrow, avoiding high slope areas and low-lying areas, and The total distance to the crops within the irrigation range is the shortest; at the same time, it is convenient to realize the arrangement of rectangular and triangular nozzles; when the branch pipe is made of hard plastic pipes, the rectangular or triangular spraying can be realized only by turning the combined four-way at a certain angle, but the nozzles The location cannot be changed arbitrarily. Compared with the "one"-shaped pipeline design, the double-branch pipe design has branch pipe diversion, smaller pipe diameter, longer laying length of main pipe, and convenient expansion of unit form and irrigation area. On the other hand, the other side of the nozzle is connected to the plug. When a small plot needs irrigation or emergency drought relief, the plug can be disassembled, and several groups of double-pipe nozzles are connected in series to form a "one" shape for sprinkling irrigation.

When the main pipe and branch pipe are made of hard plastic pipes, it can facilitate the fixing of the pipes in one irrigation season; when the plastic-coated hoses are used, since the joints of the pipes are combined four-way instead of nozzles, it is convenient to roll and realize. mechanized operation. For areas with poor economic conditions, the system can be simplified to the configuration of only the main pipe and several groups of double branch pipes, and the branch pipes are held in hand for irrigation, which can satisfy the irrigation of several plots or several farmers at the same time. For hilly areas or intercropping of crops, two rows of different types of nozzles can be installed on both sides of the double branch pipe of the system at the same time to meet the requirements of different working pressures of nozzles or different irrigation quotas of crops in different plots.

The combined double-branch pipe fixed-moving dual-purpose sprinkler irrigation system, the double-branch nozzle combination can be installed and moved in groups, and each branch main pipe is combined with the corresponding double-branch nozzle to form a unit module, which is convenient to control. The dry pipe is fixed and easy to rewind, so the pipes of the system can be laid out in an orderly manner during the irrigation season, improving work efficiency; the distance between the nozzles is adjustable, and it is easy to realize rectangular and triangular spraying, branch pipes diverge, the diameter of the pipe becomes smaller, and the cost is reduced; in the drought-resistant season , can use double-pipe nozzles to form groups and connect them in series, or hand-hold branch pipes for watering. The system combination is flexible; at the same time, it has a strong adaptability to conditions such as terrain slope, plot shape, and crop planting methods.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and examples of implementation.

1 and 2, a nozzle and pipeline fixing device according to the present invention consists of a water pump unit 1, a main pipe 2, a branch control valve 3, a sub-main pipe 4, several groups of double-branch nozzle combinations 5, and a combined four-way connection 6 , Plug 7 composition. The double-branch nozzle combination 5 is composed of symmetrically arranged double-branch pipes 8 and two nozzles 9, the main pipe 2 is connected to the water pump unit 1, the branch control valve 3 is located at the inlet of the branch pipe 4, and the double-branch pipe 8 is connected to the branch pipe. 4 are connected by combination four-way 6. The main pipe 2, branch pipe 4 and double-branch pipe 8 adopt hard plastic pipes or plastic-coated flexible pipes. The plug 7 is used to block the double branch pipe 8, instead of the control valve, which saves the cost. As shown in Fig. 2, the combination cross 6 is formed by interlacing two tees through quick joints 10, wherein the upper tee 11 is connected to the double branch pipe 8, the lower tee 12 is connected to the branch pipe 4, and the quick joint 10 is connected to the threaded joint. In comparison, the rotation angle is small when installing and dismounting, and the efficiency is higher.

When the system is installed, as shown in Figure 10, the main pipe 2 and sub-main pipe 4 are laid out first, and then the double-branch nozzle combination 5 is connected. Among them, the double-branch nozzle combination 5 can be installed indoors in advance to ensure that the connections are not damaged and then transported to the field for installation. When disassembling, the opposite is true.

When moving, refer to Figure 1 and Figure 10, just unscrew the combination cross 6, move the nozzles 9 on both sides to the vicinity of the combination cross 6, and then wind the double branch pipe 8 into a coil 18 centered on the above tee 11. The branch nozzle combination 5 can be moved at the same time, and finally the main pipe 4 is rolled up from the end of the pipe and moved to the next plot; the main pipe 2 and the main pipe 4 can also be fixed on the ground as a fixed part of the irrigation system , and other parts as movable parts; or all pipelines are fixed in an irrigation season.

When the nozzle combination or spacing needs to be adjusted, as shown in Figure 3, Figure 4, and Figure 5, it is only necessary to use the combined four-way, 6 as the center, and move the position of the double-pipe nozzle combination 5 to achieve a rectangular or triangular nozzle arrangement. Way.

Specific implementation plan one

As shown in Figure 3, according to the specific conditions of the terrain and wind direction, the double branch pipes 8 are vertically arranged with the branch pipes 4, the double branch pipes 8 are symmetrically distributed on both sides of the branch pipes 4, and the nozzles 9 are arranged in a rectangular shape.

Specific implementation plan two

As shown in Figure 4, the nozzles are arranged in a triangle. According to the specific conditions of terrain and wind direction, all the double-branch nozzle combinations 5 rotate a certain angle, such as moving from the initial position 13 to the desired position 14. The nozzles 9 are arranged in a triangle.

Specific implementation plan three

As shown in Figure 5, in order to adapt to the spraying of corners or irregular plots, the sprinkler 9 on the side can be moved to any position, so that more crops can be irrigated and not sprayed to the roadside; When there is a high slope or a big tree, the position of the nozzle 9 can be moved arbitrarily within the length radius of the branch pipe 8. When the system uses micro-nozzle irrigation, the nozzle 9 and the branch pipe 8 can move like a drop arrow following the planting position of the crops, thereby saving water resources to the greatest extent, while adapting to changes in crop planting methods in different irrigation seasons, thus having the function of micro-irrigation advantage. In the system, two rows of nozzles are combined to spray at the same time, which improves the uniformity and can be used in both spray and micro irrigation systems.

Specific implementation plan four

During emergency drought relief, as shown in Figure 6, for a plot with a small area of about 10 mu, several groups of double-branch nozzle combinations 5 can be connected in series to spray irrigation in the shape of a "one"; in Figure 7, for 10-50 mu For large plots on the left and right, the standpipe and support under the nozzle can be omitted. At this time, the sprinkler irrigation system is the configuration of the main pipe 2, several sets of double branch pipes 8 and the nozzle 9. The nozzle 9 is hand-held for irrigation, or the nozzle 9 is omitted. As one of the methods of pipeline water irrigation, it can satisfy the irrigation of several fields or several farmers at the same time, and the utilization rate of the equipment of the system is increased.

Specific implementation plan five

When intercropping and intercropping are used for slope irrigation and intercropping in hilly areas, as shown in Figure 8, the branch pipe 4 can be arranged along the contour line 15, and the double-branch nozzle combination 5 can be arranged along the mountain from top to bottom. At this time, when the slope is greater than a certain When the value is higher, the shower nozzle 9 with higher terrain can adopt the nozzle with lower pressure, and the nozzle 9 with low terrain can adopt the higher nozzle with pressure.

Specific implementation plan six

As shown in Figure 9, when crops are intercropped, the two crops planted at the same time either have different water requirements or are in different growth stages, and the irrigation quotas will be different, so the requirements for the intensity of spray irrigation and the intensity of raindrop impact are different. When the difference When it is obvious, different types of nozzles 9 need to be used. For dwarf crops or crops with low water demand 16, use smaller nozzles 9, and for high-stalk crops or crops with large water requirements 17, use larger nozzles 9. Connect the branch pipe 8 on the side of the small spray head to supplement the installation of the spray head 9. Compared with the light and small mobile sprinkler irrigation units arranged in a "one" shape, the connection of the sprinkler head 9 and the system expansion of the system are more flexible.
