Description

Technical Field

[0001] This invention relates to the field of sowing and fertilization technology, specifically to an adaptive fertilization device for medicinal herb cultivation. Background Technology

[0002] In the cultivation of Chinese medicinal herbs, fertilization and sowing are two crucial steps, as they directly affect the growth quality, yield, and final medicinal efficacy of the herbs.

[0003] In the traditional cultivation of Chinese medicinal herbs, fertilization and sowing mostly rely on manual operations. This method is not only inefficient, but also makes it difficult to ensure the uniformity and precision of fertilization and sowing, thus affecting the growth and quality of the medicinal herbs.

[0004] In order to overcome the shortcomings of traditional planting methods, adaptive fertilization and seeding devices have been gradually introduced into the planting of Chinese medicinal herbs in recent years.

[0005] These devices enable simultaneous fertilization and sowing through mechanization and automation, greatly improving planting efficiency.

[0006] However, existing adaptive fertilization and seeding devices still have some shortcomings in terms of functionality and adaptability.

[0007] For example, while some devices can achieve simultaneous fertilization and sowing, they are often limited to a single sowing method, only allowing for either hill sowing or row sowing. Summary of the Invention

[0008] The purpose of this invention is to provide an adaptive fertilization device for medicinal herb cultivation, which solves the problem that existing devices can only perform single hole sowing or row sowing.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an adaptive fertilization device for medicinal herb cultivation, comprising a support mechanism, the support mechanism including a movable platform, a sowing and fertilization mechanism mounted on the movable platform, the sowing and fertilization mechanism including a vertically slidable box, a support being slidably connected to the lower part of the box, a first material tray and a second material tray being symmetrically rotatably connected inside the support, a seed trough and a fertilizer trough being provided inside the box, and a feeding hopper being connected to the lower part of both the seed trough and the fertilizer trough, with the two feeding hoppers respectively located above the first material tray and the second material tray;

[0010] The first and second material trays are provided with grooves on their side walls, and the ports of the two hoppers are respectively attached to the side walls of the first and second material trays.

[0011] When the support is located directly below the box, the seeds and fertilizer are discharged through the grooves on the side walls of the first and second trays, respectively. When the support moves out of the lower part of the box, and the box moves down, the seeds and fertilizer are discharged through the two hoppers, respectively.

[0012] Preferably, a mounting frame is fixedly connected to the moving platform, a cylinder is connected to the mounting frame, a connecting seat is fixedly connected to the output end of the cylinder, and two turntables are symmetrically rotatably connected to the connecting seat. Each of the two turntables is provided with a protrusion, which slides in the groove. When the two turntables slide axially synchronously on the first material tray and the second material tray respectively, the volume of the groove changes to increase or decrease the amount of seeds and fertilizer fed.

[0013] Preferably, a first pin is fixedly connected to the connecting seat, and the first pin is slidably connected to the bracket. After the cylinder shortens so that the pin cap of the first pin abuts against the bracket, the cylinder continues to shorten to pull the bracket out of the lower part of the housing.

[0014] Preferably, the first tray and the second tray are respectively connected to a first rotating shaft and a second rotating shaft, and the first rotating shaft and the second rotating shaft are rotatably connected to the bracket.

[0015] Preferably, a second pin is inserted into the mounting bracket, and a tension spring is sleeved on the second pin. The two ends of the tension spring are respectively fixedly connected to the mounting bracket and the pin cap of the second pin. After the cylinder shortens so that the pin cap of the first pin abuts against the bracket, when the cylinder continues to shorten, the slider on the bracket pushes the second pin to retract, thereby allowing the bracket to slide relative to the mounting bracket.

[0016] Preferably, it also includes a vibration mechanism. The moving platform has a feeding trough. The vibration mechanism includes two electric telescopic rods connected to the wall of the feeding trough. The output ends of the two electric telescopic rods are connected to a discharge hopper. After the box body moves down, the electric telescopic rods extend so that the discharge hopper docks with the feeding hopper.

[0017] Preferably, the mobile platform is connected to a watering mechanism, which includes a water tank, a water pipe connected to the water tank, a nozzle connected to the water pipe, a solenoid valve installed on the water pipe, a stationary iron core connected to the mounting bracket, and a plurality of first moving iron cores connected to the second rotating shaft. The plurality of first moving iron cores correspond one-to-one with the plurality of grooves on the second material tray. When each first moving iron core is aligned with the stationary iron core, the solenoid valve is opened.

[0018] Preferably, a second moving iron core is fixedly connected to the bracket. After the bracket is moved out of the lower part of the housing, the second moving iron core is aligned with the stationary iron core so that the solenoid valve is normally open.

[0019] Preferably, a sliding rod is slidably connected inside the moving platform, the sliding rod is inserted into the water pipe, a protruding plate is provided at the end of the discharge hopper, and a striking plate is connected to the sliding rod. After the discharge hopper and the discharge hopper are connected, the striking plate contacts the protruding plate. A limit ring is provided on the sliding rod, and a first electromagnetic ring is provided inside the moving platform. A spring is connected between the limit ring and the first electromagnetic ring. When the water flow in the water pipe impacts the sliding rod, the nozzle sprays water, and the limit ring strikes the protruding plate.

[0020] Preferably, a second electromagnetic ring is connected inside the moving platform. When the bracket is located at the lower part of the box, the second electromagnetic ring and the first electromagnetic ring are magnetically attracted to each other, so that the water pipe and the nozzle are constantly connected. When the bracket is moved out of the lower part of the box, the second electromagnetic ring and the first electromagnetic ring are magnetically repelled, and the water flow in the water pipe impacts the slide rod and slides back and forth.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] An adaptive fertilization device for medicinal herb cultivation includes a support mechanism, which includes a movable platform on which a sowing and fertilization mechanism is mounted. The sowing and fertilization mechanism includes a vertically sliding box, with a support slidably connected to the lower part of the box. A first material tray and a second material tray are symmetrically rotatably connected within the support. The box contains a seed trough and a fertilizer trough, with hoppers connected to the lower parts of both the seed trough and the fertilizer trough. The two hoppers are respectively located above the first and second material trays. Grooves are formed on the side walls of both the first and second material trays, and the ports of the two hoppers are respectively attached to the side walls of the first and second material trays. When the support is directly below the box, seeds and fertilizer are discharged through the grooves on the side walls of the first and second material trays, respectively. When the support moves out of the lower part of the box and the box moves down, seeds and fertilizer are discharged through the two hoppers, respectively.

[0023] Seeds and fertilizer are placed into the seed trough and fertilizer trough respectively. The motor drives the first and second feed trays to rotate synchronously, so that the grooves on the two feed trays move alternately to the lower part of the corresponding feed hopper, so that the seeds and fertilizer are discharged through the first and second feed trays respectively. At this time, the discharge speed of the seeds and fertilizer is accelerated or decreased by the drive speed of the motor. At this time, the Chinese medicine is sown in holes and fertilized at the same time. After the support slides out of the lower part of the box, the box moves down, and the seeds and fertilizer are discharged directly through the feed hopper, thus enabling the Chinese medicine seeds to be sown in rows and fertilized at the same time.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-8This embodiment provides a technical solution: an adaptive fertilization device for medicinal herb cultivation, including a support mechanism 100. The support mechanism 100 includes a moving platform 110, on which a sowing and fertilization mechanism 200 is installed. The sowing and fertilization mechanism 200 includes a vertically sliding box 210. A bracket 220 is laterally slidably connected to the lower part of the box 210. A first material tray 221 and a second material tray 222 are symmetrically rotatably connected inside the bracket 220. A seed trough 211 and a fertilizer trough 212 are provided inside the box 210. A feeding hopper 2 is connected to the lower part of both the seed trough 211 and the fertilizer trough 212. 13. Two hoppers 213 are respectively disposed on the upper part of the first material tray 221 and the second material tray 222; grooves are provided on the side walls of the first material tray 221 and the second material tray 222, and the ports of the two hoppers 213 are respectively attached to the side walls of the first material tray 221 and the second material tray 222; when the support 220 is located directly below the box body 210, the seeds and fertilizers are discharged through the grooves on the side walls of the first material tray 221 and the second material tray 222, respectively; when the support 220 moves out of the lower part of the box body 210, and after the box body 210 moves down, the seeds and fertilizers are discharged through the two hoppers 213, respectively.

[0035] The working mechanism of the adaptive fertilization device provided in this embodiment is as follows:

[0036] The support mechanism 100 can be equipped with casters and a separate power drive for movement, or it can be placed on a farming vehicle. Seeds and fertilizers are respectively put into the seed trough 211 and fertilizer trough 212. The motor drives the first feed tray 221 and the second feed tray 222 to rotate synchronously, so that the grooves on the two feed trays move alternately to the lower part of the corresponding feed hopper 213, so that the seeds and fertilizers are discharged through the first feed tray 221 and the second feed tray 222 respectively. At this time, the discharge speed of the seeds and fertilizers is accelerated or decreased by the drive speed of the motor. At this time, the Chinese medicine is sown in holes and fertilized at the same time. After the support 220 slides out of the lower part of the box 210, the box 210 moves down, and the seeds and fertilizers are directly discharged through the feed hopper 213, so that the Chinese medicine seeds can be sown in rows and fertilized at the same time.

[0037] Among the optional methods in this embodiment, the more preferred one is:

[0038] A mounting frame 120 is fixedly connected to the moving platform 110. A cylinder 260 is connected to the mounting frame 120. A connecting seat 270 is fixedly connected to the output end of the cylinder 260. Two turntables 250 are symmetrically rotatably connected to the connecting seat 270. Both turntables 250 are provided with protrusions. The protrusions slide in the grooves. When the two turntables 250 slide axially on the first material tray 221 and the second material tray 222 simultaneously, the volume of the grooves changes to increase or decrease the amount of seeds and fertilizer fed.

[0039] During hill sowing, when it is necessary to control the amount of seeds sown per hill or when the seeds are large, the control cylinder 260 is shortened. At this time, the cylinder 260 drives the connecting seat 270 to slide away from the corresponding material tray, thereby increasing the volume of the groove on the material tray, which can hold more seeds and fertilizer. Conversely, the control cylinder 260 is extended, which makes the volume of the groove smaller. The protrusion on the turntable 250 is always engaged in the groove on the corresponding material tray, so that the material tray can drive the turntable 250 to rotate, ensuring that the volume of the groove can be maintained stably.

[0040] Among the optional methods in this embodiment, the more preferred one is:

[0041] A first pin 280 is fixedly connected to the connecting seat 270. The first pin 280 is slidably connected to the bracket 220. After the cylinder 260 shortens so that the pin cap of the first pin 280 abuts against the bracket 220, the cylinder 260 continues to shorten to pull the bracket 220 out of the lower part of the housing 210.

[0042] When the cylinder 260 shortens to maximize the volume of the groove, the pin cap of the first pin 280 abuts against the bracket 220. At this time, the cylinder 260 continues to shorten, which can drive the bracket 220 to move out of the lower part of the box 210. The box 210 is driven to rise and fall by an electric slider or a hydraulic rod. When the bracket 220 is completely moved out of the lower part of the box 210, the box 210 is driven to move downward, so that strip seeding can be performed subsequently.

[0043] Among the optional methods in this embodiment, the more preferred one is:

[0044] A first rotating shaft 230 and a second rotating shaft 240 are respectively connected to the first material tray 221 and the second material tray 222, and the first rotating shaft 230 and the second rotating shaft 240 are rotatably connected to the bracket 220.

[0045] The first rotating shaft 230 and the second rotating shaft 240 are connected by a belt and pulley drive. The two material trays can be driven to rotate synchronously by a motor, or the first material tray 221 and the second material tray 222 can be driven to rotate synchronously by two motors respectively.

[0046] Among the optional methods in this embodiment, the more preferred one is:

[0047] A second pin 290 is inserted into the mounting bracket 120, and a tension spring 291 is sleeved on the second pin 290. The two ends of the tension spring 291 are respectively fixedly connected to the mounting bracket 120 and the pin cap of the second pin 290. After the cylinder 260 shortens so that the pin cap of the first pin 280 abuts against the bracket 220, when the cylinder 260 continues to shorten, the slider on the bracket 220 pushes the second pin 290 to retract, so that the bracket 220 slides relative to the mounting bracket 120.

[0048] The second pin 290 is designed to block the support 220 when the volume of the groove of the tray is changed, preventing the first tray 221 and the second tray 222 from moving out of the lower part of the box 210. When it is necessary to move the support 220 out of the lower part of the box 210, the continued contraction of the cylinder 260 can cause the slider on the support 220 to push the rounded end of the second pin 290 to retract, ensuring that the support 220 can continue to slide.

[0049] Regarding the structure of the vibration mechanism 400, specifically:

[0050] The moving table 110 is provided with a feeding trough 130. The vibration mechanism 400 includes two electric telescopic rods 410 connected to the wall of the feeding trough 130. The output ends of the two electric telescopic rods 410 are connected to the discharge hopper 420. After the box 210 moves down, the electric telescopic rods 410 extend so that the discharge hopper 420 docks with the feeding hopper 213.

[0051] After the housing 210 moves down, the electric telescopic rod 410 extends, so that the upper port of the discharge hopper 420 connects with the upper port of the discharge hopper 213, and the lower port of the discharge hopper 420 is smaller than the lower port of the discharge hopper 213, so that the discharge speed of seeds and fertilizers during row sowing is not too fast.

[0052] Regarding the structure of the irrigation mechanism 300, specifically:

[0053] The irrigation mechanism 300 includes a water tank 310, a water pipe 320 connected to the water tank 310, a nozzle 330 connected to the water pipe 320, a solenoid valve 390 installed on the water pipe 320, a stationary iron core 392 connected to the mounting bracket 120, and multiple first moving iron cores 391 connected to the second rotating shaft 240. The multiple first moving iron cores 391 correspond one-to-one with multiple grooves on the second material tray 222. When each first moving iron core 391 is aligned with the stationary iron core 392, the solenoid valve 390 is opened.

[0054] During hill sowing, fertilizer and seeds are discharged as the first feed tray 221 and the second feed tray 222 rotate. Multiple first moving iron cores 391 correspond one-to-one with multiple grooves. Thus, when seeds and fertilizer are discharged, one of the first moving iron cores 391 is directly opposite the stationary iron core 392. At this time, the solenoid valve 390 opens, allowing water in the water tank 310 to be sprayed into the sowing hole through the nozzle 330. The water tank 310 is pressurized by a pressure pump to ensure that the water flow has sufficient pressure to be sprayed through the nozzle 330.

[0055] Among the optional methods in this embodiment, the more preferred one is:

[0056] A second moving iron core 393 is fixedly connected to the bracket 220. After the bracket 220 is moved out of the lower part of the housing 210, the second moving iron core 393 and the stationary iron core 392 are aligned so that the solenoid valve 390 is normally open.

[0057] During row sowing, the support 220 slides out of the lower part of the box 210. At this time, the second moving iron core 393 on the support 220 is directly opposite the stationary iron core 392, so that the solenoid valve 390 is in the normally open state, allowing the nozzle 330 to continuously spray water for irrigation during row sowing.

[0058] Among the optional methods in this embodiment, the more preferred one is:

[0059] A sliding rod 340 is slidably connected inside the moving platform 110. The sliding rod 340 is inserted into the water pipe 320. A protruding plate 430 is provided at the end of the discharge hopper 420. A striking plate 341 is connected to the sliding rod 340. After the discharge hopper 420 is connected to the discharge hopper 213, the striking plate 341 contacts the protruding plate 430. A limit ring 350 is provided on the sliding rod 340. A first electromagnetic ring 360 is provided inside the moving platform 110. A spring 380 is connected between the limit ring 350 and the first electromagnetic ring 360. When the water flow in the water pipe 320 impacts the sliding rod 340, the nozzle 330 sprays water, and the limit ring 350 strikes the protruding plate 430.

[0060] During seeding, the first electromagnetic ring 360 and the second electromagnetic ring 370 are magnetically attracted to each other. At this time, the part of the slide rod 340 does not block the connection between the nozzle 330 and the water pipe 320, so that when the solenoid valve 390 is opened, the water can be sprayed through the nozzle 330.

[0061] Among the optional methods in this embodiment, the more preferred one is:

[0062] The moving platform 110 is connected to a second electromagnetic ring 370. When the support 220 is located at the lower part of the housing 210, the second electromagnetic ring 370 and the first electromagnetic ring 360 are magnetically attracted to each other, so that the water pipe 320 and the nozzle 330 are always connected. When the support 220 is moved out of the lower part of the housing 210, the second electromagnetic ring 370 and the first electromagnetic ring 360 are magnetically repelled, and the water flow in the water pipe 320 impacts the slide bar 340 to slide back and forth.

[0063] During row sowing, the first electromagnetic ring 360 and the second electromagnetic ring 370 repel each other magnetically. At this time, the end of the slide rod 340 blocks the connection between the nozzle 330 and the water pipe 320. The solenoid valve 390 is in the normally open state. The water flow impacts the slide rod 340 and the spring 380 pushes the limiting ring 350, causing the slide rod 340 to slide back and forth. In addition, when the discharge hopper 420 is pushed by the electric telescopic rod 410, the convex plate 430 on the discharge hopper 420 moves into the striking range of the striking plate 341. As the slide rod 340 slides back and forth, the striking plate 341 continuously strikes the convex plate 430, so that the vibration is transmitted to the discharge hopper 420, thereby preventing the discharge of seeds and fertilizer from being obstructed.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
