Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, and in particular to a sprinkler irrigation device for leafy vegetables grown in cold high-altitude areas. Background Technology

[0002] Cool-climate vegetables (such as cabbage, bok choy, cauliflower, and lettuce) refer to vegetable varieties that are suitable for growing in regions with cool summer climates. Their core advantage lies in their ability to supply scarce fresh vegetables to the market when it is difficult to supply fresh vegetables in plains areas due to high summer temperatures, thus possessing high economic value. To meet this off-season production demand, cool-climate vegetable production bases need to be established in specific regions with cool summer climates, such as high mountains and plateaus. However, the terrain in these specific regions is generally complex and varied, mainly characterized by scattered fields, uneven ground, and unequal roads, making it difficult for traditional large-scale, wide-span spraying equipment pulled by large agricultural tractors to operate in these areas.

[0003] To solve the above-mentioned technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202021189179.7 is a sprinkler irrigation device for carrot planting, including a base plate. An adjustment device is fixedly connected to the lower end of the base plate. Universal wheels are fixedly connected to the four corners of the lower end of the adjustment device. Two left spraying devices and a right spraying device are fixedly connected to the upper left and upper right parts of the base plate, respectively. The two left spraying devices and the right spraying devices have the same structure and are symmetrically distributed. A water bucket is fixedly connected to the middle of the upper part of the base plate. The upper end of the water bucket is fixedly connected to the bucket lid by screws. A stirring device is inserted through the upper end of the bucket lid, and the lower part of the stirring device is located inside the water bucket. Water inlets are opened on the upper left and upper right parts of the bucket lid. A push handle is fixedly connected to the lower right part of the base plate and the right end of the adjustment device.

[0004] However, the above-mentioned existing technology has the following technical problems: Cool-climate vegetables (especially leafy vegetables) are usually characterized by high planting density, low plant height and multiple overlapping leaves. The above-mentioned sprinkler irrigation device for carrot planting sprays pesticides through left and right spraying devices set on the upper part of the base plate, which makes the sprayed pesticides mainly concentrated on the upper part of the leaves. The pesticide coverage rate of the middle and lower layers of cool-climate vegetables and the underside of the leaves is low, resulting in poor pest and disease control. In order to achieve the control effect, it is necessary to spray pesticides repeatedly, which not only reduces the actual utilization rate of pesticides and increases production costs, but may also cause environmental pollution. Utility Model Content

[0005] In view of this, it is necessary to provide a spray irrigation device for leafy vegetables in cool high-altitude areas, which can improve the pesticide application rate in the lower and middle layers of cool vegetables and on the underside of leaves, so as to achieve the control effect without repeated spraying of pesticides.

[0006] This utility model provides a sprinkler irrigation device for cool-climate leafy vegetables in high-altitude areas, including a frame component, a drive component, a pesticide storage component, and a spraying component.

[0011] Preferably, the medicine storage component further includes a protective component, which is detachably installed on the top surface of the fixing plate and encloses the power supply component to prevent the medicine sprayed by the irrigation assembly from coming into contact with the power supply component and causing a short circuit.

[0012] Preferably, two sprinkler assemblies are symmetrically arranged on both sides of the first end of the bogie. Each sprinkler assembly includes a lifting group, an adjusting rod, and at least one adjusting slider. The fixed end of the lifting group is fixedly installed on the top surface of the head frame. The first end of the adjusting rod is fixedly connected to the lifting end of the lifting group to adjust the height of the adjusting rod. Each adjusting slider is slidably installed on the adjusting rod, and a spraying rod is detachably installed at the bottom of each adjusting slider to adjust the horizontal position of the spraying rod by moving each adjusting slider.

Detailed Implementation

[0022] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please refer to Figure 1 This utility model provides a sprinkler irrigation device 10 for leafy vegetables in cool high-altitude areas, including a frame component 20, a drive component 30, a pesticide storage component 40, and a spraying component 50. The drive component 30 is installed at the first end of the frame component 20 and is used to drive the frame component 20 to move in the field. The pesticide storage component 40 is installed on the top surface of the second end of the frame component 20 and is used to store pesticide solution. The spraying component 50 includes two identical sprinkler assemblies 51, which are symmetrically installed on the top surface of the frame component 20. Each sprinkler assembly 51 includes at least one spraying rod 511. 1. At least two nozzles 512 are provided in the vertical direction to spray pesticides on cool-climate vegetables from different heights simultaneously. In this way, the drive component 30 drives the frame component 20 to move in the field. At the same time, the pesticide solution in the pesticide storage component 40 is extracted and transported to the two spraying components 51. Then, the pesticide solution is sprayed on the cool-climate leafy vegetables from different heights through multiple nozzles 512 provided in the vertical direction on each spraying rod 511. This allows the pesticide solution to be sprayed on different height parts of the cool-climate leafy vegetables at the same time, improving the pesticide coverage rate of the middle and lower layers of cool-climate vegetables and the underside of the leaves. Thus, the control effect can be achieved without repeated spraying of pesticides.

[0024] In this embodiment, each nozzle 512 is an atomizing nozzle 512, so that the liquid sprayed from each nozzle 512 can be evenly sprayed onto all parts of the leafy vegetables in the cool climate.

[0025] In this embodiment, the spraying rod 511 is available in various models to select different models according to the plant height of the cool-climate leafy vegetables. Specifically, different models of spraying rods 511 differ in length and preset nozzle spacing. Operators can select the appropriate model of spraying rod 511 according to the actual plant height of the cool-climate leafy vegetables to ensure that nozzles 512 of different heights can spray the key parts of the cool-climate leafy vegetables.

[0026] Please refer to Figure 2 Furthermore, the frame components 20 include a front frame 21, a rear frame 22, and a bogie 23. The bottom of the front frame 21 is rotatably mounted with at least two symmetrically arranged front wheels 24 for moving the front frame 21 in the field. The rear frame 22 is rotatably connected to the front frame 21, and the bottom of the rear frame 22 is rotatably mounted with at least one rear wheel 25 so that the rear frame 22 can follow the front frame 21. The first end of the bogie 23 is fixedly connected to the front frame 21 so that the direction of travel of the front frame 21 can be changed by rotating the second end of the bogie 23.

[0027] In this embodiment, the width of both the front frame 21 and the rear frame 22 is smaller than the width of the ditch between two ridges in the field, so that the front frame 21 and the rear frame 22 can move along the ditch in the field.

[0028] Please refer to Figure 2 Furthermore, the second end of the bogie 23 is symmetrically equipped with two handles 26 for easy gripping by the operator. Specifically, when the frame component 20 moves in the field, the operator grips the handles 26 of the bogie 23. Since the front frame 21 and the first end of the bogie 23 are fixedly connected, when the high-altitude cold-climate leafy vegetable irrigation device 10 needs to turn left, the operator pulls the handle 26 to the right, causing the front frame 21 to drive the front wheel 24 to turn to the left under the pull of the bogie 23, thus changing the direction of travel of the front wheel 24 to the left; when the high-altitude cold-climate leafy vegetable irrigation device 10 needs to turn right, the operator pulls the handle 26 to the left, causing the front frame 21 to drive the front wheel 24 to turn to the right under the pull of the bogie 23, thus changing the direction of travel of the front wheel 24 to the right.

[0029] Please refer to Figure 2Furthermore, the drive component 30 includes an engine 31 and a transmission component 32. The fixed end of the engine 31 is fixedly mounted on the top of the front frame 21, and the drive end is drivenly connected to the first end of the transmission component 32. The second end of the transmission component 32 extends from the top of the front frame 21 into its bottom and is drivenly connected to each front wheel 24 to transmit the power from the drive end of the engine 31 to each front wheel 24, thereby causing the engine 31 to drive each front wheel 24 to rotate.

[0030] In this embodiment, the engine 31 is a small diesel engine 31, which drives the front wheel 24 to rotate, providing a continuous and reliable traction force for a high-altitude, cold-weather leafy vegetable sprinkler irrigation device 10, enabling it to move continuously in the field.

[0031] Please refer to Figure 3 Furthermore, the medicine storage component 40 includes a medicine tank 41, a fixing frame 42, a fixing plate 43, a medicine pump 44, and a power supply component 45. The medicine tank 41 is installed on the top surface of the rear frame 22 and is used to store the medicine liquid. The top of the medicine tank 41 has an injection port. The fixing frame 42 is detachably installed on the top surface of the rear frame 22 and is snapped onto the surface of the medicine tank 41 to fix the medicine tank 41 on the top surface of the rear frame 22. The fixing plate 43 is fixedly installed on the top surface of the fixing frame 42. The input end of the medicine pump 44 extends from the injection port to the bottom of the medicine tank 41, and the output end is connected to two irrigation assemblies 51 to draw the medicine liquid from the medicine tank 41 and send it to each irrigation assembly 51. The power supply component 45 is fixedly installed on the fixing plate 43 and is electrically connected to the medicine pump 44 to provide power to the medicine pump 44.

[0032] Please refer to Figure 4 Furthermore, the medicine storage component 40 also includes a protective component 46, which is detachably installed on the top surface of the fixing plate 43 and encloses the power supply component 45 to prevent the liquid medicine sprayed by the irrigation assembly 51 from coming into contact with the power supply component 45 and causing a short circuit. Specifically, the protective component 46 provides a physical barrier for the power supply component 45, effectively reducing the risk of the power supply component 45 coming into contact with conductive liquid, thereby ensuring the safe operation of the power supply component 45.

[0033] Please refer to Figure 1 , Figure 5 and Figure 6Furthermore, two sprinkler assemblies 51 are symmetrically arranged on both sides of the first end of the bogie 23. Each sprinkler assembly 51 includes a lifting group 513, an adjusting rod 514, and at least one adjusting slider 515. The fixed end of the lifting group 513 is fixedly installed on the top surface of the head frame 21. The first end of the adjusting rod 514 is fixedly connected to the lifting end of the lifting group 513 to adjust the height of the adjusting rod 514 through the lifting group 513. Each adjusting slider 515 is slidably installed on the adjusting rod 514. A spraying rod 511 is detachably mounted on the bottom of each adjusting slider 515 to adjust the horizontal position of the spraying rod 511 by moving each adjusting slider 515. Each spraying rod 511 is mounted on the adjusting rod 514. The hose on slider 515 is connected to the output end of the pump 44, so that the liquid medicine drawn by the pump 44 from the medicine tank 41 enters the spray rod 511 along the hose and is sprayed onto the cool-season leafy vegetables from the nozzle 512 on the spray rod 511. Specifically, the height of the adjusting rod 514 is adjusted by the lifting assembly 513, thereby adjusting the height of each spray rod 511, so as to adjust the height of each spray rod 511 according to the plant height of the cool-season vegetables to accommodate cool-season vegetables of different plant heights; by sliding each adjusting slider 515 along the adjusting rod 514, the horizontal position of each spray rod 511 is adjusted, so as to adjust the spray rod 511 according to the row spacing of the cool-season vegetables to accommodate cool-season vegetables with different row spacings.

[0034] In this embodiment, each adjusting slider 515 has a connection hole to facilitate the installation of a hose; specifically, one end of the hose extends from the connection hole and communicates with the spray rod 511, and the other end is connected to the output end of the pump 44.

[0035] Please refer to Figure 1 , Figure 5 and Figure 6 Furthermore, the lifting assembly 513 includes a lifting frame 5131, a lifting slider 5132, a lead screw 5133, and a lifting motor 5134. The bottom of the lifting frame 5131 is fixedly installed on the top surface of the head frame 21. The lifting slider 5132 is slidably installed on the lifting frame 5131 along the lifting track. The lifting slider 5132 is fixedly connected to the first end of the adjusting rod 514 so that the height of the adjusting rod 514 in the vertical direction can be adjusted by adjusting the position of the lifting slider 5132 on the lifting frame 5131. The first end of the lead screw 5133 is rotatably connected to the top end of the lifting frame 5131, and the second end extends vertically downward and passes through the lifting slider 5132, and is threadedly engaged with the lifting slider 5132. The fixed end of the lifting motor 5134 is fixedly installed on the top surface of the head frame 21, and the driving end is drivenly connected to the second end of the lead screw 5133 so that the driving end of the lifting motor 5134 drives the lead screw 5133 to rotate, thereby driving the lifting slider 5132 to rise and fall along the lifting frame 5131.

[0036] In this embodiment, the lifting frame 5131 has a lifting track, and the lifting slider 5132 is engaged in the lifting track to achieve a sliding connection between the lifting frame 5131 and the lifting slider 5132.
