Description

Technical Field

[0001] This invention relates to the technical field of foliar spraying, specifically to a foliar spraying device for planting. Background Technology

[0002] Rice is a cereal crop of the genus Oryza. The grains it produces are called paddy rice. After the husks are removed, the paddy rice is called brown rice. After the bran layer is removed from the brown rice, you can get white rice. Rice is classified into indica rice, japonica rice, early rice, mid-late rice, glutinous rice and non-glutinous rice according to the type of paddy rice.

[0003] During rice cultivation, foliar spraying with liquid fertilizers such as water-soluble silicon fertilizer and selenium fertilizer can improve the rice's salt tolerance or resistance to heavy metal toxicity, thus enabling it to adapt to planting in saline or heavy metal-contaminated soils. However, since the spraying liquid is applied to the rice leaves through nozzles, the rice plants sway from side to side in windy weather, resulting in some of the sprayed liquid not reaching the leaves and causing waste. Therefore, a foliar spraying device for planting is needed. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. It primarily offers a foliar spraying device for planting, which solves the technical problem mentioned in the background that when spraying in windy weather, some of the spray solution fails to reach the rice leaves due to the shaking of the rice plants, resulting in waste of the spray solution.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A foliar spraying device for planting includes a connecting plate fixed to a spraying vehicle at one end. Multiple telescopic components are fixed to the lower side of the connecting plate away from the spraying vehicle. A connecting block is fixed to the end of each telescopic component away from the connecting plate. Horizontal plates are fixed to the upper parts of both sides of the connecting block. Wind deflectors are hinged to the opposite sides of the lower surfaces of the two horizontal plates. Multiple first elastic components are fixed between the wind deflectors and the horizontal plates. Spraying components are hinged to the lower parts of both sides of the connecting block. The opposite sides of the two spraying components contact the first wind deflectors. A water inlet pipe connected to a water pump inside the spraying vehicle is inserted into the upper surface of the connecting block. The water inlet pipe is connected to the spraying components.

[0007] Preferably, the telescopic component includes a cylinder, which is fixedly connected to the side of the connecting plate facing the connecting block. A round rod is inserted into the end of the cylinder away from the connecting plate, and the end of the round rod away from the cylinder is fixedly connected to the connecting block. The annular surface of the round rod has a plurality of vertically arranged round holes, and the annular surface of the cylinder has a threaded hole. A fixing bolt is threaded into the threaded hole, and the fixing bolt passes through the threaded hole and extends into the round hole.

[0008] Preferably, the spraying component includes hinge plates, and hinge plates are hinged to the lower parts of both sides of the connecting block. A retaining member is fixed between the two hinge plates. Multiple nozzles are hinged to the opposite sides of the two hinge plates. The nozzles are connected to the inlet pipe through a water distribution pipe. A support plate is provided on the opposite sides of the two hinge plates. Multiple support rods are hinged to the side of the support plate facing the hinge plates. The side of the support rod away from the support plate is hinged to the hinge plate. Multiple small holes are opened on the side of the support plate facing the hinge plates. The nozzles are inserted into the small holes. Multiple hinge rods are hinged to the center of the lower surface of the connecting block. The end of the hinge rod away from the connecting block is hinged to the support plate.

[0009] Preferably, the supporting member includes a rectangular tube, with multiple vertical rods fixedly connected to the upper surface of the rectangular tube. The end of the vertical rod away from the rectangular tube is fixedly connected to a connecting block. Adjusting members are slidably connected to both the left and right sides inside the rectangular tube. A second elastic member is fixedly connected to the side of the adjusting member facing the opening end of the rectangular tube. A rectangular rod is fixedly connected to the end of the second elastic member away from the adjusting member. The end of the rectangular rod away from the second elastic member is in contact with a hinge plate.

[0010] Preferably, the adjusting component includes a sliding plate that slides inside a rectangular tube. Rectangular grooves are provided on both the left and right sides of the upper surface of the rectangular tube. A screw is inserted into the rectangular groove. One end of the screw inside the rectangular tube is connected and fixed to the sliding plate. A nut is slidably connected to the upper surface of the rectangular tube, and the nut is threadedly connected to the screw.

[0011] Preferably, each of the two horizontal plates has a vertically arranged inclined plate extending to both sides fixed on the opposite sides of its back.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By hinged plates on the lower surfaces of both sides of the connecting block, and then mounting the nozzles on the hinged plates, when the wind blows the rice to one side, the wind deflector is simultaneously tilted by the wind and squeezes the hinged plates, causing the hinged plates to tilt the nozzles in the direction of the wind flow. This allows the sprayed liquids, such as silicon fertilizer, selenium fertilizer, or pesticides, to be sprayed onto the rice leaves as much as possible, reducing the waste of sprayed liquids.

[0014] 2. By sliding an adjustment structure consisting of a slide plate, screw, and nut inside a rectangular tube, the angle between the hinge plate and the connecting block can be adjusted to accommodate rice of different sizes.

[0015] 3. By using a hinged structure consisting of a support rod, a support plate, and a hinge rod hinged to opposite sides of two hinged plates, the tilt angle of the nozzle is adjusted using the hinged structure. This allows the baffle to tilt the hinged plates, and the adjustment structure to adjust the tilt of the hinged plates ensures that the spray liquid from the nozzle is accurately directed towards the rice leaves. This avoids situations where the angle between the two hinged plates and the connecting plate is too large, preventing the spray liquid from failing to reach the rice leaves, and preventing situations where the angle between the two hinged plates and the connecting plate is too small, causing the spray liquid to spray onto the opposite hinged plate.

[0016] 4. The nozzle height can be adjusted by connecting the connecting plate and the connecting block through a telescopic structure consisting of a cylinder and a rod, thus allowing the device to be used for rice at different heights.

[0017] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please refer to the appendix carefully. Figure 1-5 A foliar spraying device for planting includes a connecting plate 1 fixed to a spraying vehicle at one end. Multiple cylinders 7 are fixed to the lower side of the end of the connecting plate 1 away from the spraying vehicle. A round rod 6 is inserted into the end of the cylinder 7 away from the connecting plate 1. A fixed connecting block 8 is connected to the end of the round rod 6 away from the cylinder 7. Multiple vertically arranged round holes 25 are opened on the annular surface of the round rod 6. A threaded hole is opened on the annular surface of the cylinder 7. A fixing bolt 24 is threaded into the threaded hole. The fixing bolt 24 passes through the threaded hole and extends into the round hole 25.

[0029] Horizontal plates 5 are fixedly connected to the upper parts of both sides of the connecting block 8. Wind deflectors 3 are hinged to the opposite sides of the lower surfaces of the two horizontal plates 5. Multiple first elastic elements 9, which are springs, are fixedly connected between the wind deflectors 3 and the horizontal plates 5 and are in a stretched state. Hinges 4 are hinged to the lower parts of both sides of the connecting block 8, and these hinges 4 contact the wind deflectors 3. Multiple nozzles 20 are hinged to the opposite sides of the two hinges 4. A water inlet pipe connected to the water pump inside the spray truck is inserted into the upper surface of the connecting block 8. 18. The nozzle 20 is connected to the inlet pipe 18 via the water distribution pipe 19. Support plates 21 are provided on the opposite side of the two hinge plates 4. Multiple support rods 22 are hinged to the side of the support plate 21 facing the hinge plate 4. The side of the support rod 22 away from the support plate 21 is hinged to the hinge plate 4. Multiple small holes are opened on the side of the support plate 21 facing the hinge plate 4. The nozzle 20 is inserted into the small holes. Multiple hinge rods 23 are hinged at the center of the lower surface of the connecting block 8. The end of the hinge rod 23 away from the connecting block 8 is hinged to the support plate 21.

[0030] By hinged to the lower surfaces of both sides of the connecting block 8, and then mounting the nozzle 20 on the hinged plate 4, when the wind blows the rice to one side, the wind deflector 3 is simultaneously tilted by the wind and squeezes the hinged plate 4, causing the hinged plate 4 to tilt the nozzle 20 in the direction of wind flow. This allows the spray liquid such as silicon fertilizer, selenium fertilizer, or pesticides sprayed by the nozzle 20 to be sprayed onto the rice leaves as much as possible, reducing waste of spray liquid. Furthermore, the height of the nozzle 20 can be adjusted by connecting the connecting plate 1 and the connecting block 8 through a telescopic structure composed of a cylinder 7 and a rod 6, thus enabling the device to meet the needs of rice of different heights.

[0031] It should be noted that the foliar spraying device provided by the present invention is not only suitable for foliar spraying of rice, but also for foliar spraying of other types of plants. Here, rice is used as an example for explanation and use only.

[0032] Multiple vertical rods 17 are fixedly connected to the lower surface of the connecting block 8. The end of each vertical rod 17 away from the connecting block 8 is fixedly connected to the rectangular tube 12. Rectangular rods 11 are inserted into both the left and right sides of the rectangular tube 12. The end of each rectangular rod 11 away from the rectangular tube 12 is in contact with the hinge plate 4. The end of each rectangular rod 11 inside the rectangular tube 12 is fixedly connected to a second elastic element 13. The second elastic element 13 is a spring and is in a compressed state. The end of the second elastic element 13 away from the rectangular rod 11 is fixedly connected to a sliding plate 14. Rectangular grooves 10 are opened on both the left and right sides of the upper surface of the rectangular tube 12. Screws 15 are inserted into the rectangular grooves 10. The end of each screw 15 inside the rectangular tube 12 is fixedly connected to the sliding plate 14. Nuts 16 are slidably connected to the upper surface of the rectangular tube 12. Nuts 16 are threadedly connected to screws 15.

[0033] By sliding an adjustment structure consisting of a slide plate 14, a screw 15, and a nut 16 within the rectangular tube 12, the angle between the hinge plate 4 and the connecting block 8 can be adjusted. This allows the hinge plate 4 to accommodate rice of different sizes. Furthermore, by hinged on opposite sides of the two hinge plates 4, a hinge structure consisting of a support rod 22, a support plate 21, and a hinge rod 23 can be used to adjust the tilt angle of the nozzle 20. This allows the baffle to tilt the hinge plate 4, and the adjustment structure to adjust the tilt of the hinge plate 4 ensures that the spray liquid from the nozzle 20 is accurately directed towards the rice leaves. This prevents the spray liquid from failing to reach the rice leaves when the angle between the two hinge plates 4 and the connecting plate 1 is too large, and prevents the spray liquid from spraying onto the opposite hinge plate 4 when the angle between the two hinge plates 4 and the connecting plate 1 is too small.

[0034] To facilitate the entry of rice between the two hinged plates 4, vertically arranged inclined plates 2 extending to both sides are connected and fixed on the opposite sides of the back of the two horizontal plates 5.

[0035] The specific operation process of this invention is as follows, taking rice as an example: the inclined plate 2 is used to slide the rice leaves into the space between the two hinge plates 4, and then the water pump in the sprayer is started to spray the spray liquid onto the rice leaves. When the wind blows outside, the wind blows the rice at an angle and blows the wind deflector 3. The wind deflector 3 squeezes the hinge plate 4, causing the hinge plate 4 to rotate inward, thus preventing the nozzle 20 from spraying the spray liquid into the water.

[0036] As the hinge plate 4 rotates inward, the distance between the nozzle 20 and the center of the lower surface of the connecting block 8 decreases. Since the length of the hinge rod 23 is fixed, when the nozzle 20 approaches the center of the lower surface of the connecting block 8, it will be supported by the hinge rod 23, causing the nozzle 20 to tilt downward. This prevents the spray liquid from not being sprayed onto the rice leaves when the angle between the two hinge plates 4 and the connecting plate 1 is too large, and prevents the spray liquid from being sprayed onto the opposite hinge plate 4 when the angle between the two hinge plates 4 and the connecting plate 1 is too small.

[0037] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
