Description

Technical Field

[0001] This utility model relates to the field of agricultural sprinkler irrigation, and in particular to an integrated sprinkler irrigation machine and sprinkler irrigation system for trenching and film laying. Background Technology

[0002] Sprinkler irrigation is an irrigation method that uses water pumps and pipeline systems or the drop of natural water sources to spray pressurized water into the air, breaking it down into small droplets that fall onto plants and the ground. Sprinkler irrigation includes stationary sprinkler irrigation, semi-stationary sprinkler irrigation, and mobile sprinkler irrigation, and is characterized by water conservation, no damage to soil structure, and strong adaptability.

[0003] Mobile sprinkler irrigation is the current trend in agricultural sprinkler irrigation, and mobile sprinkler machines are increasingly widely used in fields. There are two main types of mobile sprinkler irrigation systems for fields: pipeline water supply and ditch water supply. The main types of mobile sprinkler machines for fields are reel-type and horizontal-moving mobile sprinkler machines. Reel-type mobile sprinkler machines use pipeline water supply and drag a water hose during operation. Their movement distance is limited by the hose length, and both hose deployment and relocation require tractor towing. To address this, publication number CN109042252A proposes adding power to the sprinkler truck and designing a water tank capacity adjustment device. This allows for water addition and weight gain during forward movement, providing sufficient traction for hose deployment and enabling self-propelled spraying. Water is released during rewinding to reduce weight and lower hose reel resistance, thus solving the problem of relying on external power for hose deployment. However, this still does not solve the inconvenience caused by carrying a large hose reel and the hose length limitation during operation. Large-scale mobile sprinkler irrigation machines typically use ditches for water supply. These machines are mostly used on large, flat areas or long, narrow plots, offering high irrigation efficiency. However, they are unsuitable for small or irregular plots and require the pre-construction of high-standard irrigation ditches. Therefore, some have proposed patents to address these issues. For example, patent application CN108207581A discloses a simplified, intelligent, self-propelled, cantilevered mobile sprinkler irrigation machine. This machine features a suction pipe assembly and a power pump assembly on its walking frame. The suction pipe assembly and power pump assembly work together to draw water from the ditch and irrigate the area using the sprinkler assembly. This overcomes the problem of large sprinkler irrigation machines being unsuitable for small plots, but it also increases the density of the irrigation canal layout, raising construction costs and reducing land use efficiency. Therefore, changing the current situation of mobile sprinkler irrigation systems—characterized by bulky equipment, inconvenient operation, high cost, and limited applicability—has become a crucial issue for promoting water-saving irrigation technologies.

[0038] Example 1:

[0039] like Figures 1 to 6 As shown, this embodiment discloses a trenching, mulching, and sprinkler irrigation integrated machine, comprising:

[0040] The frame 1 is equipped with an extension arm, an irrigation pump 15 and a power assembly 14. The extension arm is mounted on the top of the frame 1 and is used to arrange the nozzles. The irrigation pump 15 is equipped with a pump suction pipe 16, which is located at the rear of the frame 1. The power assembly 14 is used to provide power.

[0041] A trenching assembly is located at the bottom of the frame 1, and the power assembly 14 is able to drive the trenching assembly to dig trenches in the ground to form channels 2.

[0042] The membrane laying assembly is located at the bottom of the frame 1 and behind the trenching assembly. The membrane laying assembly is used to lay the plastic film 6 in the channel 2. The lower end of the pump suction pipe 16 on the irrigation pump 15 extends into the channel 2 where the plastic film 6 is laid.

[0043] In this way, by using this integrated trenching, film laying, and sprinkler irrigation machine, field sprinkler irrigation can be achieved by digging trenches, laying film, and irrigating the channel 2 with plastic film 6 at the same time. It is fast, efficient, and eliminates the need for pipe dragging operations and the construction of high-standard irrigation canals. It is convenient to use and easy to popularize and promote.

[0044] Generally, water is supplied to the channel 2, which is covered with plastic film 6, through the water supply pipe 3. There can be one or more water supply pipes 3. In order to ensure smooth water flow in the channel 2, the bottom of the channel 2 can be kept at the same depth over short distances, while a certain slope is required over long distances. Therefore, it is necessary to precisely control the trenching depth and configure control equipment.

[0045] like Figure 1 and Figure 6 As shown, the trenching assembly includes a trenching cutter 4, a drive chain 41, and a hydraulic rod 42. The trenching cutter 4 is mounted on the lower end of the hydraulic rod 42 and is driven to rotate by the drive chain 41. The hydraulic rod 42 is mounted on the bottom of the frame 1 to provide downward pressure on the trenching cutter 4 and control the downward pressure depth. The power assembly 14 is connected to both the hydraulic rod 42 and the drive chain 41, providing power for the extension and retraction of the hydraulic rod 42 and the rotation of the drive chain 41. Thus, the trenching depth can be dynamically adjusted and the slope controlled by controlling the extension and retraction of the hydraulic rod 42.

[0046] To better control the descent, such as Figure 6 As shown, this solution also includes an intelligent control cabinet 19 and a slope detection unit. The intelligent control cabinet 19 is installed on the frame 1 and is connected to the power assembly 14, the irrigation pump 15 and the slope detection unit. The slope detection unit is used to detect the ground elevation data in real time during operation and feed the ground elevation data back to the intelligent control cabinet 19 in real time. The intelligent control cabinet 19 controls the power assembly 14 to adjust the extension and retraction of the hydraulic rod 42, thereby adjusting the dredging depth of the channel 2 in real time.

[0047] In one embodiment, the slope detection unit is a satellite system unit 12 mounted on the rack 1.

[0048] In another embodiment, the slope detection unit is a laser control unit, which includes a laser receiver 11 mounted on the frame 1 and a laser emitter 10 located at a distance from the ground.

[0049] The application of laser technology and satellite system 12 technology enables precise elevation measurement, thereby achieving accurate control of the slope of channel 2.

[0050] like Figure 1 As shown, in this scheme, the trenching blade 4 is a rotary tillage blade, which is composed of multiple blades of different lengths. The blades on the left and right sides are shorter than the blades in the middle, and the outer contour of the blades formed by this arrangement is arc-shaped.

[0051] Thus, the cross-section of channel 2 excavated by the trenching component is U-shaped.

[0052] like Figure 2 , Figure 3 and Figure 6As shown, the film laying assembly includes a film laying frame 61 and a film presser 7. The film laying frame 61 is fixedly installed at the bottom of the frame 1, and the film presser 7 is rotatably installed at the bottom of the frame 1 via a film presser frame 71. The film laying frame 61 is located in front of the film presser 7, and a rotatable plastic film roll is installed on the film laying frame 61. The film presser 7 is used to apply the plastic film 6 on the plastic film roll into the channel 2.

[0053] To facilitate the placement of the plastic film 6 within the U-shaped channel 2, the film press 7 is an arc-shaped roller that conforms to the outer contour of the blade.

[0054] Zhou Guoxing et al., in their study "Application of U-shaped Impermeable Plastic Components in Small Channels," demonstrated that, under the same cross-sectional geometric dimensions, U-shaped channels made of plastic products exhibit a better flow interface compared to concrete channels. The roughness coefficient of the plastic cross-section (n = 0.009) is 36% higher than that of the concrete cross-section (n = 0.014), resulting in a significant increase in flow capacity. The theoretical comprehensive flow rate of the plastic U-section is q = 0.506 m³ / s. 3 The theoretical value of the comprehensive flow rate of the concrete U-section is Q = 0.334 m³ / s. 3 / s increased by 51%.

[0055] Cao Zhengquan et al., in their study "Comparative Analysis of Several Anti-Seepage Channel Cross-Sections," demonstrated that among various cross-sectional forms of open channels, the semi-circular cross-section has the largest hydraulic radius and best flow conditions. Furthermore, using a U-shaped cross-section saves 14%–15% of the engineering work compared to using trapezoidal or rectangular cross-sections.

[0056] Therefore, with the same design slope, the U-shaped channel 2 can significantly increase the length of the channel through which water can flow smoothly, increase the irrigation area, and is convenient to construct with a small amount of work. At the same time, the U-shaped cross section makes the water flow at the bottom of the channel more concentrated, making water absorption easier and water utilization more efficient.

[0057] According to Lu Minglong's "Calculation of Head Loss of Water Conveyment Structures in Large-Scale Open Channel Water Diversion Projects", the head loss along the path is h. f The calculation formula is:

[0058] h f =Q 2 n 2 l / (A 2 R 4 / 3 )

[0059] In the formula, Q is the flow rate; n is the roughness coefficient; l is the flow path length; A is the cross-sectional area of ​​the water passage; and R is the hydraulic radius of the cross-sectional area of ​​the water passage.

[0060] The formula shows that, all other parameters being equal, the smaller the roughness coefficient, the smaller the head loss along the flow path, and the two are also quadratically related. In this scheme, the plastic membrane has a small roughness coefficient, allowing the water flow to travel further.

[0061] To prevent the plastic film 6 from falling into the channel 2 during the pressing process and affecting the film laying process, the film laying assembly is also equipped with two edge pressing wheels 72. The two edge pressing wheels 72 are rotatably mounted on both sides of the rearward-extending bracket of the presser frame 71. The two edge pressing wheels 72 are located on the upper outer side of the presser 7 and are used to press down the edges of the plastic film 6 on both sides of the channel 2.

[0062] To secure the plastic film 6 to the edges of the film on both sides of the channel 2, such as... Figure 3 , Figure 4 and Figure 6 As shown, the film-laying assembly also includes two soil-laying wheels 73 and a soil-laying wheel frame 74. The upper end of the soil-laying wheel frame 74 is installed at the bottom of the frame 1, and soil-laying wheels 73 are rotatably mounted on the left and right sides of the lower end of the soil-laying wheel frame 74. The two soil-laying wheels 73 are located on the left and right sides of the film-laying frame 61 and behind the edge-pressing wheels 72, arranged in a figure-eight shape. Thus, during the movement of the trenching, film-laying, and sprinkler irrigation integrated machine, the soil-laying wheels 73 gather soil towards the side closer to the channel 2, thereby pressing the two edges of the plastic film 6 with soil. The two soil-laying wheels 73 are located outside the two edge-pressing wheels 72.

[0063] It also includes a fertilizer pump 17 and a fertilizer preparation tank 18 mounted on the frame 1. The fertilizer pump 17 is used to draw fertilizer from the fertilizer preparation tank 18. The intelligent control cabinet 19 is connected to and controls the fertilizer pump 17, such as... Figure 6 As shown, a herbicide spray pipe 5 connected to a fertilizer pump 17 and / or an irrigation pump 15 is provided below the frame 1. The herbicide spray pipe 5 is located between the trenching assembly and the film laying assembly.

[0064] To ensure the long-term smooth flow of channel 2, the front end of the herbicide spray pipe 5 is connected to the fertilizer pump 17, and the rear end is positioned between the trenching blade 3 and the film pressing device 7, extending under the plastic film 6 being laid. Long-lasting herbicide is sprayed onto the bottom of channel 2 through the herbicide spray pipe 5. At the same time, the use of black plastic film 6 can ensure that no weeds grow under the film, keeping channel 2 unobstructed for a long time.

[0065] To ensure the mobile sprinkler machine moves along channel 2 without veering off course, such as... Figure 5 and Figure 6 As shown, it also includes a guide rod 8, the upper end of which is rotatably mounted on the bottom of the frame 1, and a guide float 81 at the lower end of the guide rod 8, which floats on the water surface of the channel 2. Two actuation rods 82 are provided on the left and right sides of the guide rod 8, which are used to provide feedback to the intelligent control cabinet 19 upon contact with the guide rod 8, thereby adjusting the moving direction of the integrated trenching, mulching, and sprinkler irrigation machine. The frame 1 is equipped with an automatic driving system; and / or, the frame 1 is equipped with a satellite navigation system.

[0066] like Figure 1 and Figure 6 As shown, it also includes a central shaft tube 20 mounted on the frame 1, and at least two pairs of wheels 101 are mounted under the frame 1. The powertrain 14 is able to control the movement of the wheels 101.

[0067] The extended arm is equipped with a water spray pipe 22 and a fertilizer spray pipe 23. Several small nozzles 25 are installed on the water spray pipe 22, and a medium nozzle 26 is installed at each end of the water spray pipe 22. A pipe cap 33 is also installed at each end of the water spray pipe 22. The middle part of the water spray pipe 22 is fixedly connected to the frame 1 through a central shaft tube 20. The central shaft tube 20 is connected to the water spray pipe 22. A large nozzle 27 is installed at the top of the central shaft tube 20. A turntable 21 is provided in the middle of the central shaft tube 20. The lower end of the central shaft tube 20 is connected to the irrigation pump 15. Several fertilizer spray nozzles 24 are installed on the fertilizer spray pipe 23.

[0068] The large sprinkler head 27 and the two medium sprinkler heads 26 can provide supplementary irrigation at different distances and ranges; on irregular plots or plots with large elevation differences, full-circle sprinkler irrigation can be performed with the large sprinkler head 27 as the center. Water control valves 28 are installed on the water pipe 22, fertilizer / pesticide pipe 23, fertilizer / pesticide nozzle 24, small sprinkler head 25, large sprinkler head 27, and medium sprinkler head 26 respectively. The intelligent control cabinet 19 is connected to and controls the water control valves 28, which have built-in water outlet sensors. When the water control valve 28 is open, if the water outlet sensor cannot detect water, a water shortage signal is issued.

[0069] When encountering hard soil during trenching, water is sprayed forward through the large nozzle 27 while trenching is being carried out, making the soil wet and soft, and making excavation easier.

[0070] The extension arm of the trenching, mulching, and sprinkler irrigation integrated machine is composed of multiple truss sections. Generally, the left and right sides of the extension arm are each composed of three truss sections spliced ​​together by folding devices 29. In this way, the three truss sections on the left and right sides of the extension arm can be folded and retracted.

[0071] The arm is equipped with a support rod 31 and a pipe rack cable 25. A rotatable camera 32 is installed on the top of the support rod 31, and the camera 32 is connected to the intelligent control cabinet 19.

[0072] The hydraulic rod 42, the soil-laying wheel frame 74, the film press frame 71, and the guide rod 8 can all be rotatably mounted under the frame 1 via a rod-frame lifter. The rod-frame lifter is controlled by the power assembly 14. When the trenching assembly, film-laying assembly, and guide rod 8 are not needed, the pole-frame lifter can be used to lift and hang the trenching assembly, film press 73, soil-laying wheel 73, and guide rod 8 under the frame 1. Alternatively, the trenching assembly, film-laying assembly, and guide rod 8 can be temporarily disassembled and stored. Generally, the rod-frame lifter includes a lifting wire 9 and a lifting reel 91. The lifting reel 91 is controlled by the power assembly 14. One end of the lifting wire 9 is fixedly connected to the lifting reel 91, and the other end is fixedly connected to the components to be lifted, such as the hydraulic rod 42, soil-laying wheel frame 74, film press frame 71, and guide rod 8.

[0073] Example 2:

[0074] During the process of trenching, mulching, and sprinkler irrigation, or in application projects after the completion of ditch construction, two or more integrated trenching, mulching, and sprinkler irrigation machines can be used side-by-side, such as... Figure 7 As shown. Specifically, the pipe caps 33 of the spray pipes 23 of two adjacent trenching and mulching sprinkler irrigation machines can be opened, and the spray pipes 23 of the two adjacent machines can be connected together via a connecting pipe. A satellite navigation system and an automatic driving system can then be used to enable multiple mobile sprinkler irrigation machines to operate side-by-side. In this way, only one water supply channel is needed; irrigation water is drawn from the main unit, allowing two or more mobile sprinkler irrigation machines to operate simultaneously. This reduces the density of ditch installations, increases the sprinkler spray width, and further reduces pipeline infrastructure and trenching costs.

[0075] This utility model also discloses a sprinkler irrigation system, including a trenching and film-laying sprinkler irrigation integrated machine as described above.
