[0001] The invention relates to the field of irrigation equipment, in particular to a water and fertilizer drip irrigation skid. Background Art

[0002] With the continuous advancement of my country's agricultural reform and the continuous development of modern agricultural technology, my country's agricultural development has entered a new historical period. Water-saving irrigation technology is a requirement for the scientific implementation of agricultural irrigation. Xinjiang is located in the northwest border area, where water resources are relatively scarce and unevenly distributed in time and space. In recent years, Xinjiang has vigorously developed efficient water-saving irrigation, which has not only laid the foundation for the development of modern agriculture, but also provided important support for the rational allocation of water resources, the optimization of industrial structure, and the transformation of economic development methods.

[0003] Drip irrigation, sprinkler irrigation and micro-irrigation are the main water-saving technologies at present. These irrigation methods all require the setting up of irrigation system heads. Conventionally, fixed buildings are used in the fields to arrange the irrigation system heads. Fixed irrigation heads obviously have the disadvantages of poor adaptability and high initial investment.

[0004] Patent document CN201420403328.3 discloses a mobile skid type irrigation system head device, which is composed of an irrigation system head, a mobile skid system, and a power drive system. The irrigation system head includes a water pump, a dispensing tank, a remote pressure gauge, a fertilizer metering pump, a dispensing tank agitator, and several metal hoses, process valves, flow meters, solenoid valves, filters, and connecting pipes. The power drive system includes a generator, a drive motor, a voltage-stabilized power supply, and an electrical instrument control module. The mobile skid system includes a skid plate that carries the irrigation system head and the power drive system, and wheels installed underneath it. The device has a simple structure and the entire irrigation system head can be moved, so it has the advantage of adapting to a wide range of plots.

[0005] However, the irrigation control area of ​​the first part of the irrigation system is limited, and it cannot be flexibly assembled according to the actual drip irrigation control area. If it is made into the first part of an irrigation system for a large area, it will be extremely inconvenient to transport. Therefore, a new water and fertilizer drip irrigation skid is developed. Summary of the invention

[0006] In view of the above-mentioned technical problems, the present invention provides a water and fertilizer drip irrigation skid.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A water and fertilizer drip irrigation skid comprises at least two skid-mounted units, wherein the skid-mounted units comprise a skid vehicle and an automatic filter, an intelligent control system, a fertilizer mixing tank and a centrifugal pump installed on the skid vehicle in a skid-mounted manner, wherein the automatic filter has a water inlet and a water outlet, the water outlet is connected to the fertilizer mixing tank through a pipeline, a regulating valve and a flow meter are arranged on the pipeline, the fertilizer mixing tank is connected to the centrifugal pump, the intelligent control system detects water and fertilizer corresponding indicators through an EC sensor and a PH sensor arranged at the water and fertilizer outlet of the fertilizer mixing tank, and adjusts the regulating valve according to preset EC values ​​and PH values;

[0009] The skid trolley is provided with positioning holes, a traction frame and a bracket. When in use, the skid trolleys of adjacent skid-mounted units are connected by connecting pieces at corresponding connection holes. When in transport state, the traction frames and brackets of the skid trolleys of adjacent skid-mounted units are connected by traction pins.

[0010] The connecting piece includes a first connecting block and a second connecting block, wherein the first connecting block is provided with a slide groove extending along its length direction, a first connecting hole is provided at the bottom of the slide groove, the second connecting block has a slider extending along its length and fitting the slide groove and a base block, the middle part of the slider is cut and divided into a first slider and a second slider, wherein the second slider is connected to the base block, the first slider and the second slider are connected by an elastic member, a second connecting hole is provided at a position of the first slider corresponding to the first connecting hole, and a third connecting hole is provided on the base block; so that the positioning hole of a prying car of an adjacent prying unit is positioned with the first connecting hole or the first connecting hole and the second connecting hole are positioned in a coincident manner, and after the positioning hole of another prying car is positioned with the third connecting hole, the prying car and the connecting piece are fixed by fasteners.

[0011] Furthermore, in the above-mentioned water and fertilizer drip irrigation skid, the skid car is provided with a groove, and the first connecting block and the base block are respectively provided with a boss that can be embedded in the groove.

[0012] Furthermore, in the above-mentioned water and fertilizer drip irrigation skid, the elastic member is a tension spring.

[0013] Furthermore, in the above-mentioned water and fertilizer drip irrigation skid, the fastener is a bolt, a pin or a stud.

[0014] The beneficial effects of the solution provided by the embodiment of the present invention are:

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Example 1

[0029] like Figures 1 to 9 As shown, the present solution provides a water-fertilizer drip irrigation skid, comprising at least two skid-mounted units, each skid-mounted unit comprising a skid vehicle 1 and an automatic filter 2, an intelligent control system 3, a fertilizer tank 4 and a centrifugal pump 5 installed on the skid vehicle 1 in a skid-mounted manner, wherein the automatic filter 2 has a water inlet 21 and a water outlet 22, and the automatic filter 2 also comprises a stirring mechanism driven by a top motor, a pressure gauge 18 is provided on the automatic filter 2, the water outlet 22 is connected to the fertilizer tank 4 through a pipeline, a regulating valve 6 and a flow meter 13 are provided on the pipeline, the fertilizer tank 4 is connected to the centrifugal pump 5, the intelligent control system 3 detects the corresponding water and fertilizer indicators through an EC sensor 8 and a PH sensor 9 provided at the water and fertilizer outlet of the fertilizer tank 4, and adjusts the regulating valve 6 according to the preset EC value and PH value;

[0030] The skid 1 is provided with a positioning hole 10, a traction frame 11 and a bracket 12. Figure 3 As shown, when in use, the skids 1 of adjacent skid-mounted units are connected at corresponding positioning holes 10 by connecting members 7; Figure 4 As shown, in the transport state, the traction frame 11 and the bracket 12 of the adjacent skid mounted unit skid 1 are connected by the traction pin 14;

[0031] like Figure 5 to Figure 7 As shown, the connecting member 7 is specifically composed of a first connecting block 70 and a second connecting block 71. Figure 5 As shown, the first connecting block 70 is provided with a slide groove 701 extending along its length direction, and a first connecting hole 702 is provided at the bottom of the slide groove 701; Figure 6As shown, the second connecting block 71 has a slider extending along its length and fitting the slide groove 701 and a base block 712, the middle part of the slider is cut into a first slider 710 and a second slider 711, wherein the second slider 711 is connected to the base block 712, and the first slider 710 and the second slider 711 are connected by an elastic member 713, and the elastic member 713 is a tension spring, such as Figure 7 As shown, when the first slider 710 and the second slider 711 are fully fitted in the slide groove 701, a second connecting hole 714 is opened at the first slider 710 corresponding to the first connecting hole 702, and a third connecting hole 715 is opened on the base block 712; the second connecting block 71 is separated from the first connecting block 70, as shown in FIG. Figure 8 and Fig. 9 As shown; the positioning hole 10 of a prying car 1 in an adjacent prying unit is positioned with the first connecting hole 702 or the first connecting hole 702 and the second connecting hole 714 are positioned in a coincident manner, and the positioning hole 10 of another prying car 1 is positioned with the third connecting hole 715, and then the prying car 1 and the connecting member 7 are fixed by the fastener 15, and the fastener 15 is a bolt, a pin or a stud, and the bolt is specifically illustrated in the figure.

[0032] like Figure 3 As shown, it is specifically shown that when in use, the skids 1 of the three skid-mounted units are connected at the corresponding connection holes through the connectors 7. If configured according to the control area of ​​the drip irrigation head, more skid-mounted units can be assembled to form a control area of, for example, 500 mu, 1000 mu, 1500 mu, 2000 mu, etc.;

[0033] like Figure 8 As shown, the bearing foundation of the drip irrigation head is basically horizontal, and the skids 1 of adjacent skid-mounted units are arranged closely.
