Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically to a fertilizer application device and a pesticide application device. Background Technology
[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide them with the nutrients they need and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and enhance economic benefits. Therefore, rational and scientific fertilization is one of the main means of ensuring food security and maintaining sustainable agricultural development.
[0003] Patent publication number CN215601932U discloses a novel fertilization and pesticide application device for soil improvement, including a body. The body is fixedly equipped with a material storage box and a liquid storage box. The bottom of the body is rotatably connected to a first rotating shaft through a connecting plate. The bottom of the material storage box is fixedly equipped with two fertilizer application components. The two fertilizer application components include a material conveying pipe, a material feeding wheel, a first gear, a second gear, and a liquid conveying pipe. The two material conveying pipes are respectively fixedly arranged on both sides of the bottom of the material storage box.
[0004] To address the problem of uneven fertilization and pesticide application affecting soil improvement, existing technologies use a storage tank to store fertilizer and a liquid storage tank to store pesticides. A first shaft drives a first gear to rotate, which in turn drives a second gear. The second gear then drives a second shaft to rotate a feeding wheel, allowing for even distribution of the fertilizer. However, this method is still limited by its large size, making it unsuitable for narrow field ridges and resulting in poor adaptability. Utility Model Content
[0005] The purpose of this utility model is to provide a fertilizer application device and a pesticide application device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A fertilizer application device includes a battery pack, a mixing mechanism on the surface of the battery pack, and a spraying mechanism on the surface of the mixing mechanism.
[0008] The mixing mechanism includes a storage tank, which is fixedly connected to the surface of the battery pack. An inlet is fixedly connected to the surface of the storage tank. A first motor is fixedly connected to the top of the inlet. The first motor is electrically connected to the battery pack. The output end of the first motor extends into the interior of the storage tank and is fixedly connected to a first bevel gear. A housing is movably connected to the surface of the first bevel gear. A second bevel gear is symmetrically distributed and movably connected to the surface of the housing. The second bevel gear meshes with the first bevel gear.
[0009] A further improvement of this utility model is that: the surface of the second bevel gear penetrates the housing and is fixedly connected to a rotating rod, the bottom end of the rotating rod is movably connected to an inclined seat, the inclined seat is fixedly connected to the inside of the storage box, the surface of the rotating rod is fixedly connected to a spiral blade, and the surface of the spiral blade is evenly distributed with connecting holes.
[0010] A further improvement of this utility model is that: a baffle is fixedly connected inside the storage box, and two sets of baffles are provided. The baffles are symmetrically distributed on both sides inside the storage box. A discharge port is fixedly connected to the bottom of the storage box, and the discharge port is threadedly connected to the surface of the spraying mechanism.
[0011] A further improvement of the present invention is that the spraying mechanism includes a first connecting seat, which is threadedly connected to the surface of the discharge port. A flexible hose is movably connected to the surface of the first connecting seat, and a second connecting seat is movably connected to one end of the flexible hose. A connecting pipe is threadedly connected to the surface of the second connecting seat.
[0012] A further improvement of this utility model is that: a guide tube is fixedly connected to the surface of the connecting tube, a handle is fixedly connected to the surface of the guide tube, a button is provided on the surface of the handle, and the button is electrically connected to the first motor.
[0013] A further improvement of this utility model is that: a horizontal tube is fixedly connected to one end of the guide tube, a material distribution seat is fixedly connected to the surface of the horizontal tube, an upper cover plate is fixedly connected to one end of the material distribution seat, a second motor is fixedly connected to the surface of the upper cover plate, and the second motor is electrically connected to the battery pack and the button.
[0014] A further improvement of this utility model is that: an arc-shaped plate is fixedly connected to the surface of the upper cover plate, a lower cover plate is fixedly connected to the bottom end of the arc-shaped plate, a connecting post is threaded to the output end of the second motor, and stirring blades are evenly distributed on the surface of the connecting post.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] 1. This utility model provides a fertilizer application device and a pesticide application device, which employs a storage box, a feed inlet, a first motor, a first bevel gear, a housing, a second bevel gear, a baffle, a rotating rod, spiral blades, a connecting hole, an inclined seat, and a discharge port. A battery pack is fixed to the surface of the mixing mechanism to supply power to both the mixing and pesticide application mechanisms. When fertilizer enters the storage box through the feed inlet, the baffle guides the fertilizer to the spiral blades, preventing it from falling directly to the bottom of the storage box. The first motor drives the first bevel gear to rotate, causing the second bevel gear, which meshes with the first bevel gear, to rotate. The mechanism drives the spiral blades on the rotating rod to rotate. The housing prevents fertilizer from directly contacting the first and second bevel gears. The fertilizer falls through the connecting holes on the surface of the spiral blades and is crushed by the spiral blades, breaking up larger clumps of fertilizer. The fertilizer is then conveyed from the discharge port to the spraying mechanism via the inclined seat. In this mechanism, the spiral blades, baffles, and discharge port are all made of PP material, which is wear-resistant and effectively reduces the overall weight. This mechanism can break up the fertilizer before spraying, making the fertilizer spread more evenly and improving the adaptability of the device.
[0017] 2. This utility model provides a fertilizer and pesticide application device, which employs a first connecting seat, a hose, a second connecting seat, a connecting pipe, a guide pipe, a handle, a button, a horizontal pipe, a distributing seat, an upper cover plate, a second motor, an arc-shaped plate, a lower cover plate, a connecting column, and a stirring blade. The first connecting seat on the surface of the hose connects to the discharge port, and the second connecting seat connects to the connecting pipe, allowing the device to be easily disassembled when not in use or for cleaning. Fertilizer enters the guide pipe through the hose and is then distributed into two distributing seats by the inclined protrusions inside the horizontal pipe. When the handle is held and the button is pressed, the second motor drives the stirring blades on the surface of the connecting column to rotate. This causes the fertilizer to be discharged from the distribution seat into the disc formed by the upper and lower cover plates. The stirring blades further disperse the fertilizer and throw it out. The arc-shaped plate blocks the fertilizer to be discharged from both sides, corresponding to the plants on both sides, avoiding waste caused by scattering fertilizer from the front and back. The disc formed by the upper and lower cover plates prevents the stirring blades from directly contacting the plants and causing damage. At the same time, the stirring blades can be replaced by removing the lower cover plate and twisting the connecting column, which improves the adaptability of the device. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] Example 1
[0026] like Figure 1-5 As shown, this utility model provides a fertilizer application device and a pesticide application device, including a battery pack 1. A mixing mechanism 2 is provided on the surface of the battery pack 1, and a pesticide application mechanism 3 is provided on the surface of the mixing mechanism 2. The mixing mechanism 2 includes a storage tank 201, which is fixedly connected to the surface of the battery pack 1. An inlet 202 is fixedly connected to the surface of the storage tank 201, and a first motor 203 is fixedly connected to the top of the inlet 202. The first motor 203 is electrically connected to the battery pack 1. The output end of the first motor 203 extends into the interior of the storage tank 201 and is fixedly connected to a first bevel gear 204. A housing 205 is movably connected to the surface of the first bevel gear 204. A second bevel gear 3 is symmetrically distributed and movably connected to the surface of the housing 205. A bevel gear 206 meshes with a first bevel gear 204. The surface of the second bevel gear 206 penetrates the housing 205 and is fixedly connected to a rotating rod 208. The bottom end of the rotating rod 208 is movably connected to an inclined seat 211, which is fixedly connected inside the storage box 201. A spiral blade 209 is fixedly connected to the surface of the rotating rod 208. The surface of the spiral blade 209 has evenly distributed connecting holes 210. A baffle 207 is fixedly connected inside the storage box 201. Two sets of baffles 207 are provided and are symmetrically distributed on both sides of the inside of the storage box 201. A discharge port 212 is fixedly connected to the bottom end of the storage box 201 and is threadedly connected to the surface of the spraying mechanism 3.
[0027] In this embodiment, the battery pack 1 is fixed to the surface of the mixing mechanism 2 to supply power to both the mixing mechanism 2 and the spraying mechanism 3. When fertilizer enters the storage tank 201 through the inlet 202, the baffle 207 guides the fertilizer to the spiral blade 209, preventing it from falling directly to the bottom of the storage tank 201. The first motor 203 drives the first bevel gear 204 to rotate, causing the second bevel gear 206 meshing with the surface of the first bevel gear 204 to rotate, which in turn drives the spiral blade 209 on the surface of the rotating rod 208 to rotate. The housing 205 prevents the fertilizer from directly contacting the first bevel gear. The fertilizer falls through the connecting hole 210 on the surface of the spiral blade 209 via the wheel 204 and the second bevel gear 206. At this time, the larger clumps of fertilizer are broken up by the mutual crushing between the spiral blades 209. The fertilizer is then conveyed to the spraying mechanism 3 through the discharge port 212 via the inclined seat 211. In this mechanism, the spiral blades 209, baffles 207, discharge port 212, etc. are all made of PP material, which is wear-resistant and can effectively reduce the overall weight. This mechanism can break up the fertilizer before spraying, making the fertilizer spread more evenly and improving the adaptability of the device.
[0028] Example 2
[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the spraying mechanism 3 includes a first connecting seat 301, which is threadedly connected to the surface of the discharge port 212. A flexible hose 302 is movably connected to the surface of the first connecting seat 301. One end of the flexible hose 302 is movably connected to a second connecting seat 303. A connecting pipe 304 is threadedly connected to the surface of the second connecting seat 303. A guide pipe 305 is fixedly connected to the surface of the connecting pipe 304. A handle 306 is fixedly connected to the surface of the guide pipe 305. A button 307 is provided on the surface of the handle 306. The button 307 is connected to the first connecting seat 302. A motor 203 is electrically connected. A horizontal tube 308 is fixedly connected to one end of a guide tube 305. A material distribution seat 309 is fixedly connected to the surface of the horizontal tube 308. An upper cover plate 310 is fixedly connected to one end of the material distribution seat 309. A second motor 311 is fixedly connected to the surface of the upper cover plate 310. The second motor 311 is electrically connected to the battery pack 1 and the button 307. An arc-shaped plate 312 is fixedly connected to the surface of the upper cover plate 310. A lower cover plate 313 is fixedly connected to the bottom end of the arc-shaped plate 312. A connecting post 314 is threadedly connected to the output end of the second motor 311. A stirring blade 315 is evenly distributed on the surface of the connecting post 314.
[0030] In this embodiment, the first connecting seat 301 on the surface of the hose 302 is connected to the discharge port 212, and the second connecting seat 303 is connected to the connecting pipe 304, making the device easy to disassemble when not in use or for cleaning. Fertilizer enters the guide pipe 305 through the hose 302 and is dispersed into the two-component feeding seats 309 by the inclined boss inside the horizontal pipe 308. In use, by holding the handle 306 and pressing the button 307, the second motor 311 drives the stirring blade 315 on the surface of the connecting column 314 to rotate, so that the fertilizer... When the fertilizer is fed from the distribution seat 309 into the disc formed by the upper cover plate 310 and the lower cover plate 313, the stirring blade 315 further disperses the fertilizer and throws it out. The arc plate 312 blocks the fertilizer to be discharged from both sides, corresponding to the plants on both sides, avoiding waste caused by spreading the fertilizer from the front and back. The disc formed by the upper cover plate 310 and the lower cover plate 313 prevents the stirring blade 315 from directly contacting the plants and causing damage. At the same time, the stirring blade 315 can be replaced by removing the lower cover plate 313 and twisting the connecting column 314, which improves the adaptability of the device.
[0031] The working principle of this fertilizer application device and pesticide spraying device will be explained in detail below.
[0032] like Figure 1-5As shown, by fixing the battery pack 1 to the surface of the mixing mechanism 2 to supply power to the mixing mechanism 2 and the spraying mechanism 3, when fertilizer enters the storage box 201 through the inlet 202, the baffle 207 guides the fertilizer to the spiral blade 209 to prevent it from falling directly to the bottom of the storage box 201. The first motor 203 drives the first bevel gear 204 to rotate, causing the second bevel gear 206 meshing with the surface of the first bevel gear 204 to rotate, which in turn drives the spiral blade 209 on the surface of the rotating rod 208 to rotate. The housing 205 avoids... The fertilizer does not directly contact the first bevel gear 204 and the second bevel gear 206. The fertilizer falls through the connecting hole 210 on the surface of the spiral blade 209, where it is crushed by the interlocking of the spiral blades 209, breaking up larger agglomerated fertilizer particles. The fertilizer is then conveyed through the discharge port 212 to the spraying mechanism 3 via the inclined seat 211. In this mechanism, the spiral blades 209, baffle 207, and discharge port 212 are all made of PP material, which is wear-resistant and effectively reduces the overall weight. This mechanism can break up fertilizer particles before spraying. The dispersion process ensures more even fertilizer distribution. The first connecting seat 301 on the surface of the hose 302 connects to the discharge port 212, and the second connecting seat 303 connects to the connecting pipe 304, allowing the device to be easily disassembled when not in use or for cleaning. Fertilizer enters the guide pipe 305 through the hose 302 and is dispersed into the two distribution seats 309 by the inclined boss inside the horizontal pipe 308. In use, by holding the handle 306 and pressing the button 307, the second motor 311 drives the stirring blade 315 on the surface of the connecting column 314 to rotate. When fertilizer is discharged from the distribution seat 309 into the disc formed by the upper cover plate 310 and the lower cover plate 313, the stirring blade 315 further disperses the fertilizer and throws it out. The arc plate 312 blocks the fertilizer to be discharged from both sides, corresponding to the planting on both sides, avoiding waste caused by spreading the fertilizer from the front and back. The disc formed by the upper cover plate 310 and the lower cover plate 313 prevents the stirring blade 315 from directly contacting the planting and causing damage. At the same time, the stirring blade 315 can be replaced by removing the lower cover plate 313 and twisting the connecting column 314, which improves the adaptability of the device.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
