Technical Field

[0001] This invention relates to the field of fertilization technology in crop cultivation, specifically to a fertilization device for horticultural crop cultivation. Background Technology

[0002] Fertilizer application devices for horticultural crops are mechanical devices specifically designed to deliver fertilizer to horticultural crops (such as flowers, vegetables, and fruit trees). Their core objective is to optimize crop nutrient absorption efficiency, reduce human intervention, and improve planting efficiency and crop quality by scientifically controlling the type, concentration, amount, and method of fertilizer application.

[0003] Currently, fertilization is required when planting flowers in horticulture. During the fertilization process using a fertilizer applicator, factors such as the different particle sizes of fertilizer and the moisture content in the air can easily cause fertilizer to clump and accumulate, leading to blockages in the fertilizer applicator during operation and affecting fertilization efficiency. Summary of the Invention

The magnetic suction plate is movably connected to a push plate. Two sets of second magnetic blocks are provided on the liquid fertilizer bin.

[0007] Preferably, a protective box is provided on one side of the solid fertilizer silo, and a motor is installed inside the protective box, with a belt at the output end of the motor.

[0008] Preferably, a one-way gear set is driven and connected to one side of the belt. One end of the one-way gear set is fixedly connected to one end of the roller, and a connecting rod is installed at the other end of the one-way gear set. The connecting rod is also equipped with a belt. One side of the belt is driven and connected to one set of rotating rods, and a belt is also provided between the two sets of rotating rods.

[0009] Preferably, the one-way gear set is provided with a telescopic rod inside, one end of the telescopic rod is fixedly connected to one end of the roller, the other end of the telescopic rod is fixedly connected to the first one-way gear, the first one-way gear is meshed with a second one-way gear, the telescopic rod is provided with a spring, one end of the spring is fixedly connected to the first one-way gear, and the other end of the spring is fixedly connected to the liquid fertilizer tank.

[0010] Preferably, a stirring rod is installed on one side of the belt on the output end of the motor, and the stirring rod is rotatably installed inside the liquid fertilizer tank.

[0011] Preferably, a row of nozzles is connected to one side of the liquid fertilizer tank, and both sides of the cover plate extend through the first folding plate and are slidably installed, with both sides of the cover plate slidably installed on the first folding plate.

[0012] Preferably, a pull rod is fixedly connected to one side of the movable plate, and the pull rod is fixedly connected to a connecting rod on one side. A fixing seat is provided on both sides of the connecting rod. The fixing seat on one side is installed at the connection between the fixing rod and the connecting rod, and the fixing seat on the other side is installed at the connection between the connecting rod and the pull rod.

[0013] Preferably, both the first and second folding plates are provided with a rotating rod on one side. The rotating rod is fixedly and rotatably installed on the liquid fertilizer tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, the eccentric wheel rotates inside the mesh conveyor belt, causing the mesh conveyor belt to vibrate. This causes the small-particle fertilizer mesh conveyor belt to fall into the lower part of the solid fertilizer bin, preventing the fertilizer from being blocked during operation due to factors such as inconsistent particle size and moisture content in the air, thus affecting the fertilization efficiency.

[0017] 2. In this invention, when the fertilizer is vibrating and sorting, the construction personnel pull the lever, which moves the moving plate at the discharge end of the solid fertilizer bin. The construction personnel can adjust the discharge amount of fertilizer inside the solid fertilizer bin according to the distance of pulling, so as to reasonably control the amount of fertilizer applied to the roots of flowers during the vegetative growth period and prevent excessive fertilizer application from affecting the growth efficiency of the flowers.

[0018] 3. In this invention, the motor drives the stirring rod to rotate, so that the fertilizer raw materials are fully mixed. Then, the mixture is evenly sprayed onto the leaves of the flowers through the nozzle. By using the solid fertilizer bin in the sorting component and the liquid fertilizer bin in the stirring component, fertilizer is applied to flowers at different stages, such as the growth period and the flowering period. This prevents problems such as poor flower growth and flower wilting caused by not applying fertilizer to different parts of the flowers according to their different growth stages.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] See Figures 1 to 4 As shown, the present invention provides a fertilization device for planting horticultural crops, including a fertilizer applicator 1. A sorting component 2 is fixedly installed on the fertilizer applicator 1. The sorting component 2 includes a solid fertilizer bin 201. A mesh conveyor belt 202 is installed inside the solid fertilizer bin 201. Rollers 203 are installed on both sides of the mesh conveyor belt 202. A push plate 211 is fixedly installed on one side of one set of rollers 203. Two sets of rotating rods 207 are installed inside the mesh conveyor belt 202. One side of one set of rotating rods 207 is connected to one set of rollers 203. Two sets of eccentric wheels 208 are fixedly installed on both sets of rotating rods 207. A movable plate 209 is movably installed at the lower end of the solid fertilizer bin 201.

[0030] When fertilizing the roots of flowers during their vegetative growth stage, the fertilization methods differ depending on the growth stage. During the vegetative growth stage, root fertilization is required, while during the flowering stage, foliar fertilization is necessary. The operator starts the fertilizer applicator 1, pouring fertilizer into the solid fertilizer hopper 201 onto the mesh conveyor belt 202. Then, the operator starts the motor 212, which rotates forward via belt 205. The motor 212 drives the one-way gear set 204 to rotate forward. When the one-way gear set 204 rotates forward, the first one-way gear 2043 and the second one-way gear 2044 mesh, transmitting power through the telescopic rod 2041, thereby driving the roller 203 to rotate. The two sets of rollers 203 work together to drive the mesh conveyor belt 202 to rotate. The unidirectional gear set 204 drives one set of rotating rods 207 to rotate via belt 205 on the connecting rod. The two sets of rotating rods 207 are connected by belt 205, which in turn drives the eccentric wheel 208 to rotate. This causes the eccentric wheel 208 to rotate inside the mesh conveyor belt 202, vibrating the mesh conveyor belt 202 and causing the fertilizer on the mesh conveyor belt 202 to vibrate. This causes the small granular fertilizer to fall into the solid fertilizer bin 201 and then be transported to the turntable of the fertilizer applicator 1 via the conveyor belt below the solid fertilizer bin 201. The turntable evenly distributes the fertilizer to the roots of the flowers during the vegetative growth period, preventing clogging caused by inconsistent fertilizer particle size and moisture content in the air, which would affect the fertilization efficiency.

[0031] Example 2:

[0032] See Figures 4 to 7 As shown, a stirring assembly 3 is installed on one side of the sorting assembly 2. The stirring assembly 3 includes a liquid fertilizer tank 301. A stirring rod 302 is rotatably installed inside the liquid fertilizer tank 301. The stirring rod 302 is connected to one of the rollers 203. A first folding plate 305 is rotatably installed at the lower end of the liquid fertilizer tank 301. A fixing rod 306 is fixedly connected to the lower end of the first folding plate 305. A connecting rod 307 is connected to one side of the fixing rod 306. One side of the connecting rod 307 is connected to the moving plate 209. A cover plate 304 is installed at the upper end of the first folding plate 305. A second folding plate 308 is rotatably installed on one side of the liquid fertilizer tank 301. A magnetic suction plate 310 is fixedly installed on one side of the second folding plate 308. The magnetic suction plate 310 is movably connected to the push plate 211. Two sets of second magnetic blocks 312 are provided on the liquid fertilizer tank 301.

[0033] Meanwhile, large-particle fertilizer is filtered through the mesh conveyor belt 202 and conveyed into the liquid fertilizer tank 301. When the motor 212 rotates, it drives the stirring rod 302 inside the liquid fertilizer tank 301 to rotate, breaking down the large-particle fertilizer. The fertilizer is then discharged through the discharge port at the bottom of the liquid fertilizer tank 301 onto the turntable of the fertilizer applicator 1. The turntable evenly spreads the fertilizer onto the roots of the flowers in the vegetative growth stage. During the vegetative growth stage, the main task of the plant is to carry out vegetative growth, that is, the growth and development of roots, stems and leaves. During this period, the plant has a large demand for nutrients, which is mainly concentrated in the roots. Therefore, spreading fertilizer on the roots is more in line with the plant's growth pattern and needs.

[0034] During the fertilizer vibration sorting and unloading process, the operator pulls the lever 210, which moves the movable plate 209 at the unloading end of the solid fertilizer bin 201. The operator can adjust the fertilizer discharge rate inside the solid fertilizer bin 201 based on the pulling distance, thus rationally controlling the amount of fertilizer applied to the roots of flowers during their vegetative growth period and preventing excessive fertilization that could negatively impact growth efficiency. Simultaneously, as the lever 210 moves the movable plate 209 at the unloading end of the solid fertilizer bin 201, the angle of movement is also adjusted via a fixed base. The connecting rod 307 moves, and the connecting rod 307 drives the first folding plate 305 to fold downward through the fixed rod 306. This controls the amount of crushed large-particle fertilizer discharged from the liquid fertilizer silo 301 while controlling the discharge amount of the solid fertilizer silo 201. At the same time, when the first folding plate 305 folds downward, it disengages from both sides of the cover plate 304, and the cover plate 304 slides downward to cover the nozzle 303, preventing solid fertilizer from entering the nozzle 303 and affecting its normal use.

[0035] When fertilizing flowers during their growth and flowering periods, the workers pour the liquid fertilizer mixture into the liquid fertilizer tank 301 and start the motor 212 to reverse. As the motor 212 reverses via the belt 205, the belt 205 drives the second one-way gear 2044 to reverse as well. Inside the one-way gear set 204, the first one-way gear 2043 and the second one-way gear 2044 no longer mesh. The second one-way gear 2044 reverses and presses downwards against the first one-way gear 2043. The first one-way gear 2043 then compresses the spring 2042 and the telescopic rod 2041, causing them to compress and preventing the one-way gear set 204 from transmitting power to the sorting component 2. The sorting component 2 then stops rotating. The motor 212 drives the stirring rod 302 to rotate, ensuring the fertilizer mixture is fully mixed. The mixture is then evenly sprayed onto the leaves of the flowers through the nozzle 303. Foliar fertilization during the growth and flowering periods allows fertilizer to enter the plant directly through the stomata or cuticle of the leaves, bypassing the soil as an intermediary. This significantly shortens the nutrient transport distance and time, enabling plants to absorb the necessary nutrients more quickly and meeting the urgent nutrient needs during flowering. Compared to soil fertilization, foliar fertilization has a higher nutrient utilization rate because some fertilizer may be fixed or lost in the soil, while foliar fertilization ensures that the fertilizer acts directly on the plant leaves, improving nutrient utilization efficiency. The solid fertilizer bin 201 in the sorting component 2 and the liquid fertilizer bin 301 in the mixing component 3 allow for separate fertilization of flowers at different stages, such as the growth and flowering periods. This prevents problems such as poor growth and flower wilting that can result from improper fertilization of different parts of the plant at different growth stages.

[0036] When fertilizing the roots of flowers during their vegetative growth period, the motor 212 rotates forward, and the sorting assembly 2 operates. The roller 203 in the sorting assembly 2 drives the push plate 211 to rotate. When the push plate 211 rotates to the position of the magnetic suction plate 310, it pushes the liquid fertilizer bin 301 towards the second magnetic block 312, causing the magnetic suction plate 310 to detach from the first magnetic block 311. Then, the magnetic suction plate 310 drives the second folding plate 308 to fold and rotate, rotating onto the second magnetic block 312. The magnetic suction plate 310 and the second magnetic block 312 are magnetically connected. Simultaneously, the second folding plate 308 folds onto the liquid fertilizer bin 301, covering it and preventing the liquid fertilizer bin 301 from becoming contaminated. When large-particle fertilizer is broken up, fertilizer dust is generated. This dust spreads to the outside world and may cause respiratory infections in construction workers, affecting their health. When spraying liquid fertilizer on flowering flowers, the construction worker presses the second folding plate 308, which causes the magnetic suction plate 310 to fold. Then, the magnetic suction plate 310 disengages from the second magnetic block 312 and moves towards the first magnetic block 311. The magnetic suction plate 310 and the first magnetic block 311 are magnetically connected. At this time, the second folding plate 308 closes the through hole between the liquid fertilizer chamber 301 and the solid fertilizer chamber 201, preventing the liquid fertilizer from flowing into the solid fertilizer chamber 201 through the through hole when the construction worker pours liquid fertilizer into the liquid fertilizer chamber 301.

[0037] When fertilizing the roots of flowers during their vegetative growth stage, the motor 212 rotates forward, and the sorting component 2 operates, vibrating the fertilizer on the mesh conveyor belt 202. This causes small fertilizer particles to fall from the mesh conveyor belt 202 into the lower part of the solid fertilizer bin 201, preventing clogging due to inconsistent fertilizer particle size. Simultaneously, the filtered fertilizer is conveyed to the liquid fertilizer bin 301, where the stirring rod 302 rotates to break up the fertilizer. The fertilizer is then evenly distributed to the roots of the flowers during their vegetative growth stage. For flowers in their flowering stage, liquid fertilizer is sprayed. The operator pours the liquid fertilizer mixture into the liquid fertilizer bin 301, the motor 212 reverses, the sorting component 2 stops operating, and the motor 212 drives the stirring rod 302 to rotate, ensuring thorough mixing of the fertilizer mixture. The mixture is then evenly sprayed onto the leaves of the flowers through the nozzle 303. This allows for reasonable fertilization of different parts of the flowers at different growth stages.

[0038] In an optional embodiment, a protective box is provided on one side of the solid fertilizer silo 201, and a motor 212 is installed inside the protective box. The protective box is used to protect the internal motor 212 and support the operation of the motor 212. A belt 205 is provided at the output end of the motor 212 for power transmission.

[0039] In an optional embodiment, a one-way gear set 204 is driven to one side of the belt 205. One end of the one-way gear set 204 is fixedly connected to one end of the roller 203, and a connecting rod is installed at the other end of the one-way gear set 204. The connecting rod is also equipped with a belt 205. One side of the belt 205 is driven to one of the sets of rotating rods 207. A belt 205 is also provided between the two sets of rotating rods 207. The motor 212 is driven by the belt 205. The motor 212 drives the one-way gear set 204 to rotate forward. At the same time, the belt 205 on the connecting rod of the one-way gear set 204 drives one of the sets of rotating rods 207 to rotate. The two sets of rotating rods 207 are driven by the belt 205. At the same time, the eccentric wheel 208 is driven to rotate, so that the eccentric wheel 208 rotates inside the mesh conveyor belt 202.

[0040] In an optional embodiment, the one-way gear set 204 is provided with a telescopic rod 2041. One end of the telescopic rod 2041 is fixedly connected to one end of the roller 203, and the other end of the telescopic rod 2041 is fixedly connected to a first one-way gear 2043. A second one-way gear 2044 meshes with the first one-way gear 2043. A spring 2042 is provided on the telescopic rod 2041. One end of the spring 2042 is fixedly connected to the first one-way gear 2043, and the other end of the spring 2042 is fixedly connected to the liquid fertilizer tank 301. The belt 205 drives the second one-way gear 2044 to reverse. The first one-way gear 2044 inside the one-way gear set 204... One-way gear 2043 and second one-way gear 2044 no longer mesh. The second one-way gear 2044 reverses and presses down on the first one-way gear 2043. The first one-way gear 2043 will press the spring 2042 and the telescopic rod 2041. The spring 2042 and the telescopic rod 2041 will be compressed, so that the one-way gear set 204 does not transmit power to the sorting component 2. The sorting component 2 no longer rotates. The spring 2042 will drive the first one-way gear 2043 to move back and forth through the telescopic rod 2041, so that when the motor 212 rotates forward, the first one-way gear 2043 and the second one-way gear 2044 can quickly mesh to transmit power.

[0041] In an optional embodiment, a stirring rod 302 is installed on one side of the belt 205 on the output end of the motor 212. The stirring rod 302 is rotatably installed inside the liquid fertilizer tank 301. Large-particle fertilizer is filtered through the mesh conveyor belt 202 and conveyed into the liquid fertilizer tank 301. When the motor 212 rotates, it drives the stirring rod 302 inside the liquid fertilizer tank 301 to rotate, breaking up the large-particle fertilizer. The fertilizer is then discharged through the discharge port at the lower end of the liquid fertilizer tank 301 onto the turntable of the fertilizer applicator 1. The turntable evenly spreads the fertilizer onto the roots of the flowers during the vegetative growth period.

[0042] In an optional embodiment, a row of nozzles 303 is connected to one side of the liquid fertilizer tank 301. The nozzles 303 are used to evenly spray the liquid fertilizer inside the liquid fertilizer tank 301 onto the leaves of the flowers. The cover plate 304 extends through the first folding plate 305 on both sides and is slidably installed. When the first folding plate 305 is folded downward, the first folding plate 305 disengages from the sides of the cover plate 304, and the cover plate 304 slides downward to cover the nozzles 303, preventing solid fertilizer from entering the nozzles 303 and affecting the normal use of the nozzles 303.

[0043] In an optional embodiment, a pull rod 210 is fixedly connected to one side of the movable plate 209, and the pull rod 210 is fixedly connected to the connecting rod 307 on one side. The connecting rod 307 is provided with fixed seats on both sides. One fixed seat is installed at the connection between the fixed rod 306 and the connecting rod 307, and the other fixed seat is installed at the connection between the connecting rod 307 and the pull rod 210. When the pull rod 210 moves the movable plate 209 at the discharge end of the solid fertilizer bin 201, the moving angle is also adjusted through the fixed seat, thereby moving the connecting rod 307, so that the connecting rod 307 drives the first folding plate 305 to fold downward through the fixed rod 306.

[0044] In an optional embodiment, a rotating rod is provided on one side of both the first folding plate 305 and the second folding plate 308. The rotating rod is fixedly and rotatably installed on the liquid fertilizer tank 301. One end of the rotating rod on the second folding plate 308 extends through the liquid fertilizer tank 301 and is fixedly installed with the magnetic suction plate 310. The rotating rod is used to adjust the folding angle of the first folding plate 305 and the second folding plate 308 on the liquid fertilizer tank 301.

[0045] In an optional embodiment, a second magnetic block 312 and a first magnetic block 311 are provided on one side of the liquid fertilizer tank 301. The magnetic suction plate 310 is magnetically connected to the second magnetic block 312 and the first magnetic block 311. The second magnetic block 312 and the first magnetic block 311 are used to magnetically connect with the magnetic suction plate 310, and then the magnetic suction plate 310 is fixed.

[0046] Working Principle: When fertilizing the roots of flowers during their vegetative growth stage, the fertilization method varies depending on the growth stage. During the vegetative growth stage, root fertilization is required, while during the flowering stage, foliar fertilization is needed. The operator starts the fertilizer applicator 1, pouring fertilizer into the solid fertilizer hopper 201 onto the mesh conveyor belt 202. Then, the operator starts the motor 212, which rotates forward via belt 205. The motor 212 drives the one-way gear set 204 to rotate forward. When the one-way gear set 204 rotates forward, the first one-way gear 2043 and the second one-way gear 2044 mesh, driving the rollers 203 through the telescopic rod 2041. The two sets of rollers 203 work together to rotate the mesh conveyor belt 202. Simultaneously, the belt 205 on the connecting rod of the one-way gear set 204 drives one set of rotating rods 207 to rotate. The two sets of rotating rods 207 are connected by belt 205. Simultaneously, the eccentric wheel 208 rotates, causing it to rotate inside the mesh conveyor belt 202, vibrating the belt and dislodging the fertilizer particles. This causes the small fertilizer particles to fall into the solid fertilizer bin 201 and then be transported via a conveyor belt below the bin to the turntable of the fertilizer applicator 1. The turntable evenly distributes the fertilizer to the roots of the flowers during their vegetative growth stage, preventing the presence of large fertilizer particles. Factors such as varying humidity levels in the air can cause blockages in the fertilizer applicator 1 during operation, affecting fertilization efficiency. Meanwhile, large-particle fertilizer is filtered through the mesh conveyor belt 202 and transported into the liquid fertilizer bin 301. When the motor 212 rotates, it drives the stirring rod 302 inside the liquid fertilizer bin 301 to rotate, breaking down the large-particle fertilizer. The fertilizer is then discharged through the discharge port at the bottom of the liquid fertilizer bin 301 onto the turntable of the fertilizer applicator 1, and the turntable evenly spreads the fertilizer onto the roots of the flowers during their vegetative growth period.

[0047] During the fertilizer vibration sorting and unloading process, the operator pulls the lever 210, which moves the movable plate 209 at the unloading end of the solid fertilizer bin 201. The operator can adjust the fertilizer discharge rate inside the solid fertilizer bin 201 based on the pulling distance, thus rationally controlling the amount of fertilizer applied to the roots of flowers during their vegetative growth period and preventing excessive fertilization that could negatively impact growth efficiency. Simultaneously, as the lever 210 moves the movable plate 209 at the unloading end of the solid fertilizer bin 201, the angle of movement is also adjusted via a fixed base. The connecting rod 307 moves, and the connecting rod 307 drives the first folding plate 305 to fold downward through the fixed rod 306. This controls the amount of crushed large-particle fertilizer discharged from the liquid fertilizer silo 301 while controlling the discharge amount of the solid fertilizer silo 201. At the same time, when the first folding plate 305 folds downward, it disengages from both sides of the cover plate 304, and the cover plate 304 slides downward to cover the nozzle 303, preventing solid fertilizer from entering the nozzle 303 and affecting its normal use.

[0048] When fertilizing flowers during their growing and flowering periods, workers pour the liquid fertilizer mixture into the liquid fertilizer container 301 and start the motor 212 in reverse. As the motor 212 reverses via the belt 205, the belt 205 drives the second one-way gear 2044 in reverse. Inside the one-way gear set 204, the first one-way gear 2043 and the second one-way gear 2044 no longer mesh. The second one-way gear 2044 reverses and presses downwards against the first one-way gear 2043. The first one-way gear 2043 then presses against the spring 2042 and the telescopic rod 2041. The spring 2042 and the telescopic rod... 2041 will compress, causing the one-way gear set 204 to stop transmitting power to the sorting component 2. The sorting component 2 will stop rotating, and the motor 212 will drive the stirring rod 302 to rotate, so that the fertilizer mixing raw materials are fully mixed. Then, it is evenly sprayed onto the leaves of the flowers through the nozzle 303. The solid fertilizer bin 201 in the sorting component 2 and the liquid fertilizer bin 301 in the stirring component 3 will fertilize the flowers at different stages, such as the growth period and the flowering period. This will prevent problems such as poor flower growth and flower withering if the flowers are not fertilized properly according to different growth stages.

[0049] When fertilizing the roots of flowers during their vegetative growth period, the motor 212 rotates forward, and the sorting assembly 2 operates. The roller 203 in the sorting assembly 2 drives the push plate 211 to rotate. When the push plate 211 rotates to the position of the magnetic suction plate 310, it pushes the liquid fertilizer bin 301 towards the second magnetic block 312, causing the magnetic suction plate 310 to detach from the first magnetic block 311. Then, the magnetic suction plate 310 drives the second folding plate 308 to fold and rotate, rotating onto the second magnetic block 312. The magnetic suction plate 310 and the second magnetic block 312 are magnetically connected. Simultaneously, the second folding plate 308 folds onto the liquid fertilizer bin 301, covering it and preventing the liquid fertilizer bin 301 from becoming contaminated. When large fertilizer particles are broken up, fertilizer dust is generated. This dust can spread to the outside world and may cause respiratory infections in construction workers, affecting their health. When spraying liquid fertilizer on flowering flowers, the construction worker presses the second folding plate 308, which causes the magnetic suction plate 310 to fold. Then, the magnetic suction plate 310 disengages from the second magnetic block 312 and moves towards the first magnetic block 311. The magnetic suction plate 310 and the first magnetic block 311 are magnetically connected. At this time, the second folding plate 308 closes the through hole between the liquid fertilizer chamber 301 and the solid fertilizer chamber 201, preventing the construction worker from pouring liquid fertilizer into the liquid fertilizer chamber 301. The liquid fertilizer flows into the solid fertilizer chamber 201 through the through hole.
