Description

Technical Field

[0001] This disclosure relates to the field of agricultural equipment technology, specifically to an adjustable multi-directional pesticide spraying structure and pesticide spraying equipment. Background Technology

[0002] In modern agricultural production, pesticide spraying is a crucial step in ensuring the healthy growth of crops and increasing crop yields. Traditional pesticide spraying structures mostly use a single nozzle or a simple arrangement of nozzles, and the nozzles are often fixed in one direction, resulting in a limited spraying range and difficulty in covering different parts of the crop plant, such as the stems, the front and back of the leaves, thus limiting the control effect.

[0003] Furthermore, existing spraying structures cannot be flexibly adjusted according to the height and planting spacing of different crops. When dealing with crops at different growth stages, the large differences in plant height and canopy width mean that fixed-structure spraying equipment cannot spray accurately, resulting in poor control effects. Utility Model Content

[0004] The purpose of this disclosure is to provide an adjustable multi-directional pesticide spraying structure that can spray different parts of crop plants, expand the range of pesticide spraying, adapt to the growth needs of different crops, improve spraying accuracy, and achieve better control effects.

[0005] To achieve the above objectives, this disclosure provides an adjustable multidirectional pesticide spraying structure, including a first rod and a second rod perpendicular to each other. The first rod extends horizontally, and a plurality of second rods are horizontally slidably disposed on the first rod. A lateral adjustment component for adjusting the distance between two adjacent second rods is connected between them. The second rod extends vertically, and a plurality of sets of omnidirectional nozzles adjustable in the vertical direction are disposed on the second rod. The omnidirectional nozzles are connected to a water tank through infusion hoses. The number of omnidirectional nozzles in each set is at least two, and the omnidirectional nozzles in each set are spaced apart on the outer periphery of the second rod.

[0006] Optionally, the lateral adjustment assembly includes a lead screw and a lead screw nut that is threadedly connected to the lead screw. One of two adjacent second rods is rotatably connected to one end of the lead screw, and the other of two adjacent second rods is fixedly connected to the lead screw nut. One of the plurality of second rods is fixedly connected to the first rod. The other second rods are provided with sliders, and the first rods are provided with slide rails. The sliders are slidably connected to the slide rails.

[0007] Optionally, the second rod is provided with a plurality of longitudinal adjustment components in sequence along the vertical direction. The plurality of longitudinal adjustment components are connected end to end, and a plurality of universal nozzles are respectively provided on the plurality of longitudinal adjustment components, and the spacing between two adjacent universal nozzles is adjusted by the longitudinal adjustment components.

[0008] Optionally, the longitudinal adjustment assembly includes an inner sleeve and an outer sleeve. The inner sleeve is slidably fitted onto the second rod, and the outer sleeve is fitted onto the second rod. One end of the outer sleeve is threadedly connected to the outer circumference of the inner sleeve, and the other end is rotatably connected to the inner sleeve of the adjacent longitudinal adjustment assembly. Each set of universal nozzles is located on the end of the inner sleeve away from the outer sleeve, wherein the uppermost inner sleeve is fixed to the corresponding second rod.

[0009] Optionally, the cross-section of the second rod is polygonal, and the inner hole of the inner sleeve is consistent with the cross-sectional shape of the second rod.

[0010] Optionally, the number of universal nozzles in the same group is two, and they are respectively vertically connected to the corresponding inner sleeves by connecting rods, wherein the connecting rods and the inner sleeves are integrally manufactured.

[0011] Optionally, the infusion tubing includes a main pipe and branch pipes. The main pipe is arranged along the axial direction of the first rod and is connected to the water tank via a pump body. The branch pipe is arranged on the second rod and connects the corresponding universal nozzle to the main pipe. The main pipe is provided with a first solenoid valve that allows flow or shut-off between the main pipe and the branch pipe.

[0012] Optionally, each of the branch pipes is provided with a second solenoid valve, which is used to control the flow or cut-off of all the universal nozzles on the corresponding second rod.

[0013] Optionally, the adjustable multi-directional pesticide spraying structure further includes a fan and a control device, wherein the fan is located behind the universal nozzle and is electrically connected to the control device.

[0014] Based on the above technical solutions, this disclosure also provides an adjustable multi-directional pesticide spraying device, including a walking frame and the above adjustable multi-directional pesticide spraying structure.

[0015] Through the above technical solution, the adjustable multidirectional pesticide spraying structure disclosed herein includes a first rod, on which multiple second rods are horizontally slidably mounted. Each second rod is equipped with multiple sets of vertically adjustable universal nozzles. Since a lateral adjustment component connects adjacent second rods, the spacing between the second rods can be adjusted to accommodate different crop planting row spacings. Because the multiple universal nozzles are vertically adjustable, they can spray the top, middle, and bottom leaves of the crop, and comprehensively cover the crop stems and the front and back of the leaves, resulting in more thorough spraying. This also meets the needs of crops at different growth stages. Furthermore, since the universal nozzles in each set are spaced apart on the outer periphery of the second rods, all-around spraying of the crop can be achieved, improving the control effect.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself; "top," "bottom," "front," and "rear" refer to the components relative to the crop in the usage state, with the closer to the crop being "front" and the farther away being "rear." Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0021] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, an adjustable multidirectional pesticide spraying structure is provided, including a first rod 1 and a second rod 2 that are perpendicular to each other. The first rod 1 extends horizontally, and a plurality of second rods 2 are horizontally slidably arranged on the first rod 1. A lateral adjustment component for adjusting the distance between two adjacent second rods 2 is connected between them. The second rods 2 extend vertically, and a plurality of sets of omnidirectional nozzles 3 that are adjustable in the vertical direction are provided on the second rods 2. The omnidirectional nozzles 3 are connected to a water tank 4 through an infusion hose. The number of omnidirectional nozzles 3 in each set is at least two, and the omnidirectional nozzles 3 in each set are spaced apart on the outer periphery of the second rods 2.

[0022] Through the above technical solution, the adjustable multidirectional pesticide spraying structure disclosed herein includes a first rod 1, on which multiple second rods 2 are horizontally slidably arranged. Each second rod 2 is equipped with multiple sets of vertically adjustable universal nozzles 3. Since a horizontal adjustment component connects adjacent second rods 2, the spacing between the second rods 2 can be adjusted to accommodate different crop planting row spacings. Because the multiple universal nozzles 3 are vertically adjustable, they can spray the top, middle, and bottom leaves of the crop, and comprehensively cover the crop stems and the front and back of the leaves, resulting in more thorough spraying and meeting the needs of crops at different growth stages. Furthermore, since the universal nozzles 3 in each set are spaced apart on the outer periphery of the second rods 2, all-around spraying of the crop can be achieved, improving the control effect.

[0023] Furthermore, the independent sliding structure of the multiple second rods 2 facilitates localized maintenance and replacement. In this disclosure, it should be noted that the horizontal direction is parallel to the ground plane, and the vertical direction is perpendicular to the horizontal plane and consistent with the direction of gravity.

[0024] According to exemplary embodiments of this disclosure, referring to Figure 1As shown, the lateral adjustment assembly includes a lead screw 11 and a lead screw nut 12 threadedly connected to the lead screw 11. One of two adjacent second rods 2 is rotatably connected to one end of the lead screw 11, and the other of two adjacent second rods 2 is fixedly connected to the lead screw nut 12. One of the multiple second rods 2 is fixedly connected to a first rod 1. Each of the other second rods 2 is equipped with a slider 13, and the first rod 1 is equipped with a slide rail 14. The slider 13 and the slide rail 14 are slidably connected. In the above technical solution, the distance between the second rods 2 can be adjusted by rotating the lead screw 11, which is convenient and allows for independent adjustment of the second rods 2. To improve the convenience of adjustment, a scale can be set on the first rod 1 to ensure faster and more accurate distance adjustment.

[0025] In this disclosure, since the lead screw and nut 12 pair has a self-locking characteristic, no additional locking device is required after adjusting the spacing by using the cooperation of lead screw 11 and lead screw and nut 12, and the result is stable and reliable.

[0026] According to exemplary embodiments of this disclosure, referring to Figure 1 As shown, multiple longitudinal adjustment components 5 are sequentially arranged along the vertical direction on the second rod 2. These components are connected end to end, and multiple sets of universal nozzles 3 are correspondingly arranged on each of the longitudinal adjustment components 5. The spacing between adjacent sets of universal nozzles 3 can be adjusted through the longitudinal adjustment components 5. With the above arrangement, the spacing between the universal nozzles 3 at different height levels can be adjusted according to the distribution density of crop leaves, and precise spraying can be performed on specific parts of the crop (such as fruits and leaves). At the same time, it can adapt to the height differences of different crops (such as low-growing vegetables and tall corn).

[0027] According to exemplary embodiments of this disclosure, referring to Figure 1 and Figure 2 As shown, the longitudinal adjustment component 5 includes an inner sleeve 51 and an outer sleeve 52. The inner sleeve 51 is slidably fitted onto the second rod 2, and the outer sleeve 52 is fitted onto the second rod 2. One end of the outer sleeve 52 is threadedly connected to the outer circumference of the inner sleeve 51, and the other end is rotatably connected to the inner sleeve 51 of the adjacent longitudinal adjustment component 5. Each set of universal nozzles 3 is located on the end of the inner sleeve 51 away from the outer sleeve 52. The uppermost inner sleeve 51 is fixed to the corresponding second rod 2. In the above technical solution, the threaded transmission between the inner sleeve 51 and the outer sleeve 52 enables stepless adjustment of the longitudinal spacing, providing high flexibility. Since both the inner sleeve 51 and the outer sleeve 52 are fitted onto the second rod 2, the compactness of the structure is improved.

[0028] In this disclosure, reference is made to Figure 2As shown, the lower end of the outer sleeve 52 can be rotatably connected to the inner sleeve 51 of the longitudinal adjustment component 5 adjacent to the lower end via a bearing. Thus, when the outer sleeve 52 is rotated, the outer sleeve 52 moves relative to the inner sleeve 51 adjacent to the upper end, and drives the inner sleeve 51 at the lower end to move, thereby realizing the vertical spacing adjustment.

[0029] According to an exemplary embodiment of this disclosure, the cross-section of the second rod 2 can be constructed as a polygonal structure, and the inner hole of the inner sleeve 51 is consistent with the cross-sectional shape of the second rod 2. The polygonal cross-section fit can prevent the inner sleeve 51 from rotating circumferentially relative to the second rod 2, ensuring the stable orientation of the universal nozzle 3, avoiding spray direction deviation due to rotation, and improving spray accuracy.

[0030] According to exemplary embodiments of this disclosure, referring to Figure 1 As shown, there are two universal nozzles 3 in the same group, and they are vertically connected to the corresponding inner sleeves 51 via connecting rods 53. The connecting rods 53 and the inner sleeves 51 are integrally manufactured. In the above technical solution, two universal nozzles 3 are set in each group. Since the two universal nozzles 3 in each group are arranged at intervals on the outer periphery of the inner sleeves 51, they can be used to spray adjacent rows of crops, thereby improving the efficiency of pesticide spraying. The integral manufacturing of the connecting rods 53 and the inner sleeves 51 reduces the assembly gap, improves the connection strength, and prevents the nozzles from loosening due to vibration or pressure during operation. At the same time, it ensures that the relative position of the universal nozzles 3 and the inner sleeves 51 is fixed, thus ensuring the stability of the spraying angle.

[0031] According to exemplary embodiments of this disclosure, referring to Figure 3 As shown, the infusion hose may include a main pipe 10 and branch pipes 20. The main pipe 10 is arranged along the axial direction of the first member 1 and is connected to the water tank 4 via a pump body 6. The pump body 6 provides power for the delivery of the pesticide solution, pumping the pesticide solution from the water tank 4 into the main pipe 10. A branch pipe 20 is arranged on the second member 2, and the branch pipe 20 connects the corresponding universal nozzle 3 to the main pipe 10. In this way, the branch pipe 20 connects the main pipe 10 to all the universal nozzles 3 on the second member 2, realizing the diversion of pesticide solution. The main pipe 10 is equipped with a first solenoid valve 7 that controls the flow or cut-off between the main pipe 10 and the branch pipe 20. The first solenoid valve 7 is used to control the opening and closing of the main pipe 10 and the branch pipe 20, and can completely close the spraying of a certain area (such as a non-operational area) to improve the pesticide utilization rate.

[0032] According to exemplary embodiments of this disclosure, referring to Figure 3As shown, each branch pipe 20 can be equipped with a second solenoid valve 8, which is used to control the flow or cut-off of all universal nozzles 3 on the corresponding second rod 2. The second solenoid valve 8 can independently control the on / off of all universal nozzles 3 on the corresponding second rod 2, realizing the start and stop of spraying of universal nozzles 3 on a single second rod 2 (such as turning off the corresponding nozzles for sparse crop areas), further refining the control and reducing pesticide waste.

[0033] According to an exemplary embodiment of this disclosure, the adjustable multidirectional pesticide spraying structure may further include a fan 9 and a control device. The fan 9 is located behind the universal nozzle 3 and is electrically connected to the control device. When the fan 9 is working, it generates airflow, which helps to flatten the blades. At the same time, the airflow generated by the fan 9 atomizes the pesticide sprayed from the universal nozzle 3 before blowing it onto the crop, expanding the diffusion range of the droplets and improving spraying efficiency. The control device can adjust the wind speed of the fan 9 to adapt to the spraying needs of different crops.

[0034] Based on the above technical solutions, this disclosure also provides an adjustable multidirectional pesticide spraying device, including a walking frame and the aforementioned adjustable multidirectional pesticide spraying structure. The walking frame includes a frame body and multiple wheels located below the frame body. The adjustable multidirectional pesticide spraying structure is installed on the walking frame body so that the walking frame body drives the adjustable multidirectional pesticide spraying structure to move. This adjustable multidirectional pesticide spraying device has all the beneficial effects of the aforementioned adjustable multidirectional pesticide spraying structure, which will not be elaborated upon here.

[0035] Reference Figures 1 to 3 As shown, the method of using the adjustable multi-directional pesticide spraying equipment of this disclosure is detailed below: First, the first rod 1 is fixedly connected to the walking frame. Then, according to the crop row spacing, the screw 11 in the lateral adjustment assembly is rotated so that the screw nut 12 drives the corresponding second rod 2 to slide along the slide rail 14, adjusting the distance between two adjacent second rods 2 to adapt to the crop row spacing. Then, according to the crop height, rotate the outer sleeve 52 of the longitudinal adjustment component 5 so that the outer sleeve 52 moves relative to the inner sleeve 51 along the height direction of the second rod 2 to adjust the vertical spacing between the two adjacent sets of universal nozzles 3. Next, adjust the spray angle of the universal nozzle 3 so that the two universal nozzles 3 in the same group and adjacent in the vertical direction are facing the upper and lower sides of the crop respectively, so that the droplets can cover the front and back of the leaves. Finally, the walking frame is activated by the control device, which drives the adjustable multi-directional pesticide spraying structure to move along the field path. At the same time, the pump body 6 is activated, and the first solenoid valve 7 and the second solenoid valve 8 corresponding to the target area are opened, so that the liquid pesticide in the water tank 4 is pumped into each branch pipe 20 through the main pipe 10. The universal nozzle 3 continuously sprays out atomized pesticide to spray the crops. During the spraying process, the fan 9 can be activated and the wind speed can be adjusted according to the crop density. The airflow blows the droplets toward the gaps in the crops and the back of the leaves to enhance the adhesion effect.

[0036] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
