Description

Technical Field

[0001] The invention relates to the technical field of equipment for protecting fruit trees, and in particular to a spraying and fertilizing device for protecting fruit trees. Background Art

[0002] Fruit tree plant protection is an important measure to ensure the healthy growth and high yield of fruit trees. It covers many aspects such as soil management, pest and disease control, pruning and shaping, cold protection and the application of modern technology. Among them, pest and disease control is mainly carried out by spraying pesticides or nutrients on fruit trees for maintenance.

[0003] Existing spraying and fertilizing equipment for fruit tree plant protection includes a liquid medicine storage cylinder and a handheld nozzle assembly for spraying liquid medicine. When spraying liquid medicine or nutrients, the liquid is pressurized into the handheld nozzle assembly through a pressurizing device, and the liquid is atomized and sprayed onto the fruit tree by relying on the atomizing nozzle of the handheld nozzle assembly to achieve spraying and fertilizing, which is similar to the handheld backpack pesticide sprayer in the prior art.

[0004] The disadvantages of the existing spraying and fertilizing equipment for fruit and vegetable plant protection are that although the existing fruit and vegetable spraying equipment can spray liquid medicine, nutrients, etc. on fruit trees in an atomized form, when the user holds the spray head component, it can generally only spray from one side of the fruit tree. In order to ensure that the liquid medicine can fully contact the entire fruit and vegetable, the operator needs to hold the spray head component and constantly change the position, and the operator also needs to change the position around the fruit tree for spraying. That is, the spray head component of the spraying device in the prior art has a relatively limited spraying angle and orientation, and the spraying and fertilizing effect is not good enough. It is necessary to manually adjust the position continuously during the spraying process, which leads to inconvenient operation, high labor intensity, and reduced efficiency of the spraying and fertilizing operation.

[0019] Beneficial effects of the present invention:

[0020] 1. The first sliding sleeve of the present invention slides along the handheld spray pipe, and drives two symmetrically distributed rotating clamp tubes to rotate and adjust the opening angle through the rack and the linkage gear.

[0022] 3. According to the present invention, when it is necessary to switch the switch state of the inner atomizing nozzle and the outer atomizing nozzle, the first sliding sleeve is pushed to slide to the corresponding position, so that the rotating clamping tube is closed, and the second sliding sleeve connected to the first sliding sleeve is continuously pushed, and the second sliding sleeve is set by the first linkage pressure plate set by the pushing action of the push rod, and all the first linkage pressure plates are synchronously deflected and squeezed by the linkage rod to squeeze the corresponding sliding column, so that each sliding column drives the corresponding first blocking block to block the corresponding inner atomizing nozzle. At the same time, when all the first linkage pressure plates are deflected, the linkage rod is laterally deflected, thereby acting on the second linkage pressure plate, and the second linkage pressure plate drives the second blocking block blocking the outer atomizing nozzle to slide and deviate through the bending pressure plate and the linkage baffle, thereby opening the outer atomizing nozzle. That is, in the whole process, it is only necessary to continuously push the first sliding sleeve and the second sliding sleeve to realize the closure of the rotating clamping tube and the switching state switching of the inner atomizing nozzle and the outer atomizing nozzle, and the operation is convenient and fast.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 7 As shown, a spraying and fertilizing device for fruit tree plant protection comprises a liquid delivery mechanism 1 and a handheld spray pipe 2. The liquid delivery mechanism 1 comprises a mobile base, a liquid storage tank mounted on the mobile base, and a pump for delivering liquid. The liquid storage tank stores nutrients or liquid medicine for spraying fruit trees. The handheld spray pipe 2 is connected to the output end of the liquid delivery mechanism 1 through a hose. The nutrients or liquid medicine to be sprayed are delivered to the handheld spray pipe 2 through the hose and then sprayed outward.

[0034] The device also includes an adjustable clamp-shaped nozzle mechanism and an angle adjustment mechanism; the adjustable clamp-shaped nozzle mechanism is arranged at one end of the handheld nozzle 2, and the adjustable clamp-shaped nozzle mechanism is used to adjust the spraying range, and can be opened according to the lateral width of the fruit tree, and spray from both sides of the fruit tree at the same time, thereby expanding the spraying range and improving the spraying efficiency;

[0035] The angle adjustment mechanism is arranged on the handheld nozzle 2, and is used to control the angle of the adjustable clamp-shaped nozzle mechanism, thereby realizing the adjustment of the spraying range.

[0036] In some specific embodiments, in combination Figure 1 , Figure 2 and Figure 5As shown, the adjustable clamp-shaped spray head mechanism includes a rotating clamp tube 3 and a spray head group. Two rotating clamp tubes 3 are provided and symmetrically distributed at one end of the handheld spray pipe 2. The rotating clamp tube 3 rotates with the handheld spray pipe 2, and the end of the rotating clamp tube 3 away from the handheld spray pipe 2 is a closed end, and the other end is connected with the handheld spray pipe 2 through a hose. The hose is bent and deformed, so that the rotating clamp tube 3 rotates while maintaining the connection with the handheld spray pipe 2. The two rotating clamp tubes 3 are both connected with the angle adjustment mechanism, and the two rotating clamp tubes 3 are driven to rotate by the angle adjustment mechanism to adjust the angle. The spray head group is distributed on the outer wall of the rotating clamp tube 3 for spraying liquid medicine.

[0037] In some specific embodiments, the rotating clamp tube 3 includes an arc segment tube body and a straight segment tube body, which are connected to each other. The arc segment tube body is located on the side away from the handheld nozzle 2, and the straight segment tube body is located on the side close to the handheld nozzle 2. The arc segment tube body is provided to facilitate the improvement of the spraying effect after the rotating clamp tube 3 is opened.

[0038] In some specific embodiments, in order to facilitate the adjustment of the opening angle of the rotating clamp tube 3, Figures 1 to 3 As shown, the angle adjustment mechanism includes a first sliding sleeve 6, a limit block 8, a rack 5 and a linkage gear 14. The first sliding sleeve 6 is slidably connected to the handheld nozzle 2, and the limit block 8 is fixedly connected to the handheld nozzle 2 to limit the stroke of the first sliding sleeve 6; two racks 5 are provided, and are symmetrically fixed on both sides of the first sliding sleeve 6, and two linkage gears 14 are provided, and are respectively rotatably connected to both sides of one end of the handheld nozzle 2 through a rotating shaft, and the linkage gear 14 is correspondingly meshed with the rack 5, and the end of the rotating clamping tube 3 close to the handheld nozzle 2 is fixedly connected to the corresponding linkage gear 14.

[0039] When it is necessary to expand the spraying range and spray liquid fertilizers and nutrients from both sides of the fruit trees at the same time, the first sliding sleeve 6 is slid laterally along the handheld spray pipe 2 according to the lateral width of the fruit trees to make it away from the rotating clamping tube 3, so that the racks 5 on both sides are synchronously moved laterally, and then the racks 5 drive the linkage gear 14 to rotate during the linear motion, and the linkage gear 14 drives the rotating clamping tube 3 to rotate, so that it is convenient to adjust the opening angle between the two rotating clamping tubes 3, as shown in the specific Figure 7 As shown, the two opened rotating clamp tubes 3 are then placed on both sides of the fruit tree, and the spraying liquid is sprayed simultaneously by the spray head group to improve the spraying and fertilizing efficiency.

[0040] In some specific implementation schemes, in order to facilitate spraying from different positions such as the periphery of the fruit tree or extending into the narrow space inside the fruit tree, nozzles with different angles are required. The nozzle group includes an inner atomizing nozzle 4 and an outer atomizing nozzle 21. There are multiple inner atomizing nozzles 4, which are fixedly arranged on the outer walls of the two rotating clamping tubes 3 close to each other. There are two outer atomizing nozzles 21, which are respectively fixedly arranged at the ends of the corresponding rotating clamping tubes 3 and are located on the side of the rotating clamping tubes 3 away from the inner atomizing nozzle 4. The inner atomizing nozzle 4 and the outer atomizing nozzle 21 can both atomize and spray the liquid medicine transported in the rotating clamping tube 3; each inner atomizing nozzle 4 is equipped with a first switch mechanism, and each outer atomizing nozzle 21 is equipped with a second switch mechanism. The two rotating clamping tubes 3 are provided with a linkage switching mechanism, and the linkage switching mechanism is used to control the switching state of the first switch mechanism and the second switch mechanism.

[0041] Among them, Figure 4 As shown, each first switch mechanism includes a slide post 12, a guide sleeve 18 and a first blocking block 20. The slide post 12 passes through one side of the rotating clamp tube 3, and an elastic rubber membrane 17 for sealing is connected between the slide post 12 and the penetration position. The guide sleeve 18 is fixedly connected to the inner side of the rotating clamp tube 3. The sizes of the guide sleeve 18 and the slide post 12 are both smaller than the inner diameter of the rotating clamp tube 3 to avoid affecting the flow of liquid. One end of the slide post 12 inside the rotating clamp tube 3 is slidably matched with the guide sleeve 18, and the slide post 12 and the guide sleeve 18 are connected to the first blocking block 20. A stretchable first spring 19 is connected between the guide sleeves 18, the first blocking block 20 is fixedly connected to the slide column 12, and the first blocking block 20 cooperates with one end of the inner atomizing nozzle 4 on the inner side of the rotating clamping tube 3, and the end of the slide column 12 on the outside of the rotating clamping tube 3 cooperates with the linkage switching mechanism. When the slide column 12 slides toward the inside of the rotating clamping tube 3, it drives the first blocking block 20 to press the inner port of the atomizing nozzle 4 in the box to block it, and at the same time the first spring 19 is stretched to generate a rebound force.

[0042] In addition, combined Figure 5 and Figure 6 As shown, the second switch mechanism includes a linkage baffle 24 and a second blocking block 23, a transition duct 22 is fixedly connected between the external atomizing nozzle 21 and the corresponding rotating clamp tube 3, the second blocking block 23 transversely penetrates one side of the transition duct 22, and the second blocking block 23 and the transition duct 22 are slidably matched, the linkage baffle 24 is arranged on the other side of the transition duct 22, and the linkage baffle 24 and the second blocking block 23 are fixedly connected through a bracket, a compressible second spring 9 is connected between the linkage baffle 24 and the transition duct 22, and the linkage baffle 24 cooperates with the linkage switching mechanism.

[0043] In some specific embodiments, in combination Figure 2 and Figure 5As shown, the linkage switching mechanism includes a first extrusion mechanism and a second extrusion mechanism. The first extrusion mechanism is arranged on the straight section tube body of the rotating clamp tube 3, and the second extrusion mechanism is arranged on the arc section tube body of the rotating clamp tube 3. The first extrusion mechanism includes a first linkage pressure plate 10 and a linkage rod 11. There are multiple first linkage pressure plates 10, which are respectively connected to the outer wall of the straight section tube body of the rotating clamp tube 3 through hinges. One end of each sliding column 12 outside the rotating clamp tube 3 is aligned and matched with the corresponding first linkage pressure plate 10, and each first linkage pressure plate 10 is rotatably connected to the corresponding position of the linkage rod 11 through a rotating shaft. A push-up mechanism that cooperates with the first linkage pressure plate 10 is slidably arranged on the handheld nozzle 2, and the push-up mechanism is connected with the angle adjustment mechanism; the second extrusion mechanism is located between the linkage baffle 24 and the corresponding first linkage pressure plate 10.

[0044] In some specific embodiments, in combination Figure 2 and Figure 3 As shown, the ejection mechanism includes a second sliding sleeve 7, a push rod 13 and a limit spring 16. The second sliding sleeve 7 is slidably connected to the handheld nozzle 2. The second sliding sleeve 7 is connected to the first sliding sleeve 6 through the limit spring 16. Two push rods 13 are provided and are respectively fixedly connected to both sides of the second sliding sleeve 7. The end of each push rod 13 is aligned with the corresponding first linkage pressure plate 10. The first sliding sleeve 6 and the second sliding sleeve 7 are fixedly provided with a protruding handle 15.

[0045] When it is necessary to extend into some narrow space inside the fruit tree to spray the inside with medicine, the first sliding sleeve 6 and the second sliding sleeve 7 are driven by the protruding handle 15 to slide synchronously along the handheld spray pipe 2, so that the two rotating clamping tubes 3 are clamped together. Figure 1As shown, it is convenient to penetrate into some narrow spaces on the inner side of the fruit tree. At this time, the inner atomizing nozzles 4 distributed on the two rotating clamping tubes 3 will correspond to each other, and the outer ports of the inner atomizing nozzles 4 that are in contact with each other will be blocked with each other. When the rotating clamping tubes 3 are clamped together, the first sliding sleeve 6 cannot continue to slide and is in contact with the limit block 8. At this time, the second sliding sleeve 7 can continue to be pushed or the two protruding handles 15 can be directly pinched, so that the second sliding sleeve 7 compresses the limit spring 16, and then drives the push rod 13 to continue to move forward, and the push rod 13 squeezes the first linkage pressure plate 10 at the position close to it, and the corresponding first linkage pressure plate 10 is deflected. At the same time, the first linkage pressure plate 10 also drives the first linkage pressure plates 10 distributed at other positions on the straight section pipe body to deflect synchronously through the linkage rod 11, respectively. The corresponding sliding column 12 is squeezed, so that each first blocking block 20 moves to block the inner port of the corresponding inner atomizing nozzle 4, thereby effectively ensuring that the inner atomizing nozzle 4 is blocked at this time and the liquid medicine cannot flow out. When the first linkage pressure plate 10 is deflected, the linkage rod 11 is driven to move laterally, and the linkage rod 11 pushes and acts on the second squeezing mechanism. The second squeezing mechanism blocks the inner atomizing nozzle 4 distributed on the arc segment tube body, and also acts on the linkage baffle 24. The linkage baffle 24 drives the second blocking block 23 to slide away from the inner side of the transition duct 22, so that the transition duct 22 is opened, so that the liquid in the rotating clamp tube 3 is conveniently sprayed from the outer atomizing nozzle 21, so that the inner atomizing nozzle 4 and the outer atomizing nozzle 21 are switched, and medicine is sprayed at different positions.

[0046] In some specific embodiments, the second extrusion mechanism includes a second linkage pressure plate 25, and the second linkage pressure plate 25 is provided with a plurality of them, and is respectively movably connected to the outer wall of the arc segment tube body of the rotating clamp tube 3 through a hinge, and each second linkage pressure plate 25 is respectively aligned with the corresponding sliding column 12, and the second linkage pressure plate 25 distributed at the position where one end of the arc segment tube body is close to the straight segment tube body is aligned with the end of the linkage rod 11, and each second linkage pressure plate 25 is fixedly connected to a bent pressure plate 26, and the linkage baffle 24 is matched with the corresponding bent pressure plate 26. When all the first linkage pressure plates 10 deflect and squeeze the corresponding sliding columns 12, the linkage rod 11 will move laterally in conjunction, thereby pushing the corresponding second linkage pressure plates 25 to deflect. When each second linkage pressure plate 25 deflects and squeezes the corresponding sliding column 12, it will also squeeze the next second linkage pressure plate 25 through the connected bent pressure plate 26, thereby making it easier for all the second linkage pressure plates 25 to deflect, and the bent pressure plate 26 on the last second linkage pressure plate 25 squeezes the linkage baffle 24, causing it to drive the second blocking block 23 to move laterally.

[0047] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0048] When it is necessary to spray liquid medicine from both sides of the outside of the fruit tree, the first sliding sleeve 6 is slid horizontally along the handheld nozzle 2 to move it away from the rotating clamping tube 3, so that the racks 5 on both sides are synchronously moved horizontally, and then the racks 5 drive the linkage gear 14 to rotate during linear motion, and the linkage gear 14 rotates with the rotating clamping tube 3, so that the opening angle between the two rotating clamping tubes 3 reaches a suitable size, and then the two opened rotating clamping tubes 3 are placed on both sides of the fruit tree. At this time, the distributed first linkage pressure plates 10 and the second linkage pressure plates 25 are not squeezed, so the first blocking blocks 20 corresponding to the inner atomizing nozzles 4 are away from the corresponding inner atomizing nozzles 4, and the inner atomizing nozzles 4 are in an open state, while the outer atomizing nozzles 21 are blocked by the second blocking blocks 23 at this time, and the liquid medicine transported to the rotating clamping tube 3 will be sprayed out through the inner atomizing nozzles 4, so that it is convenient to spray liquid fertilizers and nutrients from both sides of the fruit tree at the same time.

[0049] When it is necessary to extend into some narrow space inside the fruit tree to spray the inside with medicine, the first sliding sleeve 6 and the second sliding sleeve 7 are driven by the protruding handle 15 to slide synchronously along the handheld spray pipe 2, so that the two rotating clamping tubes 3 are clamped together. Figure 1 As shown, it is convenient to penetrate into some narrow spaces inside the fruit tree. At this time, the inner atomizing nozzles 4 distributed on the two rotating clamping tubes 3 will correspond to each other, and the outer ports of the inner atomizing nozzles 4 that are in contact with each other will be blocked with each other. When the rotating clamping tubes 3 are clamped together, the first sliding sleeve 6 cannot continue to slide and is in contact with the limit block 8. At this time, the second sliding sleeve 7 can be pushed further or the two protruding handles 15 can be directly pinched, so that the second sliding sleeve 7 compresses the limit spring 16, and then drives the push rod 13 to continue to move forward, and the push rod 13 squeezes the first linkage compression spring 16 near the position. The first linkage pressure plate 10 corresponding to the inner atomizing nozzle 4 is deflected, and the first linkage pressure plate 10 also drives the first linkage pressure plates 10 distributed at other positions on the straight section tube body to deflect synchronously through the linkage rod 11, respectively squeezing the corresponding sliding column 12, and each sliding column 12 drives the corresponding first blocking block 20 to move and block the inner port of the corresponding inner atomizing nozzle 4, thereby effectively ensuring that the inner atomizing nozzle 4 is blocked at this time and the liquid medicine cannot flow out, and in this process, the first spring 19 is stretched to generate a rebound force, which is convenient for the subsequent sliding column 12 to bring the first blocking block 20 to reset;

[0050] When the first linkage pressure plate 10 is deflected, the linkage rod 11 is driven to move laterally, and the linkage rod 11 pushes the corresponding second linkage pressure plate 25, and the corresponding second linkage pressure plate 25 is deflected, and the corresponding sliding column 12 is squeezed, and the next second linkage pressure plate 25 is squeezed through the connected bent pressure plate 26, so that all the second linkage pressure plates 25 are deflected, and the bent pressure plate 26 on the last second linkage pressure plate 25 is squeezed on the linkage baffle 24, so that it drives the second blocking block 23 to move laterally away from the inner side of the transition duct 22, so that the transition duct 22 is opened, thereby opening the outer atomizing nozzle 21, and facilitating the liquid in the rotating clamp tube 3 to be sprayed from the outer atomizing nozzle 21, realizing the switching between the inner atomizing nozzle 4 and the outer atomizing nozzle 21, and spraying medicine at different positions.

[0051] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
