Description

Technical Field

[0001] This utility model belongs to the technical field of seedling cultivation and fertilization devices, and relates to a fertilization device for forest seedling cultivation. Background Technology

[0002] Fertilizer application devices for forest seedling cultivation are tools or mechanical equipment specifically designed for the growth stage of seedlings. They are used to deliver fertilizers, such as solid granules, liquids, or mixed fertilizers, to the root zone of seedlings, optimize nutrient absorption efficiency, and promote healthy growth of seedlings.

[0003] Chinese Patent (Publication No.: CN218104155U) discloses a fertilization device for seedling cultivation, including a base, a box fixed to the top of the base, a pair of pushers fixed to the top of the base, a concave arc-shaped baffle fixed inside the box, and a three-way pipe connected to the bottom center of the concave arc-shaped baffle. Discharge pipes are installed obliquely on both sides of the box, and the side ends of the two discharge pipes extend into the box. A collection frame is fixed to the side end of the discharge pipe, and the collection frame corresponds to the discharge end of the three-way pipe. The three-way pipe is equipped with a control mechanism for controlling the opening and closing of the three-way pipe, which can automatically fertilize the seedlings, and can open and use the corresponding discharge pipe according to the seedling planting situation.

[0004] When using the above technology, the following technical problems were found in the existing technology: The fertilization device in this patent diverts fertilizer to the left and right discharge pipes through a three-way pipe. The fertilizer is discharged linearly on one or both sides of the discharge pipe at a fixed angle. However, in reality, the root systems of most seedlings are horizontally distributed and commonly arranged in a circular or radial pattern. The fertilizer coverage area caused by this device is mainly concentrated in the strip-shaped areas on the left and right sides of the roots, making it difficult to match the distribution of fertilizer with the natural distribution of the root system. This can easily lead to local overload or deficiency of nutrients in the roots of the seedlings. Utility Model Content

[0005] The technical problem this invention aims to solve is that the fertilizer application device in this patent uses a three-way pipe to divert fertilizer to the left and right discharge pipes. The fertilizer is discharged linearly along one or both sides of the discharge pipe at a fixed angle. However, in reality, the root system of most seedlings is horizontally distributed and often arranged in a circular or radial pattern. The fertilizer coverage area caused by this device is mainly concentrated in the strip-shaped areas on the left and right sides of the roots, making it difficult to match the distribution of fertilizer with the natural distribution of the root system. This can easily lead to local nutrient overload or deficiency in the roots of the seedlings.

[0006] The present invention discloses a fertilization device for cultivating forest seedlings, comprising a trolley, wherein fertilizer boxes are symmetrically installed at one end of the trolley, and the top of the fertilizer boxes is covered with a lid. An adjusting bracket is fixedly connected to the end of the trolley away from the fertilizer box, and connecting frames are slidably connected to both ends of the adjusting bracket. A fertilization ring is connected to one end of the connecting frame.

[0007] A fertilizer applicator is mounted on a trolley and is used in conjunction with a fertilizer ring.

[0008] The fertilizer application component includes a lead screw, a servo motor, and a second slider. The servo motor is installed at one end of the adjustment bracket, and the lead screw is rotatably installed inside the adjustment bracket, with one end of it being connected to the output end of the servo motor. The lead screw and nut pair is connected to a first slider, one end of which is fixedly connected to a connecting frame, and the second slider is fixedly connected to both ends of the connecting frame. The second slider and the adjustment bracket are slidably connected.

[0009] The fertilization assembly also includes a limiting frame and a retaining ring. The limiting frame is fixed inside the fertilization ring, and the retaining ring slides through the inside of the fertilization ring. A push rod is fixed to the end of the fertilization ring, and one end of the push rod passes through the limiting frame and the inside of the fertilization ring. A return spring is provided between the limiting frame and the retaining ring.

[0010] The fertilization assembly further includes a first trapezoidal slider and a spring column. The first trapezoidal slider is fixedly connected to the end of the push rod away from the inside of the fertilization ring. The inclined surface of the first trapezoidal slider is slidably connected to a second trapezoidal slider. The fixed end of the spring column is fixedly connected to the surface of the fertilization ring. The movable end of the spring column is connected to one end of the second trapezoidal slider. A push plate is installed at the end of the second trapezoidal slider away from the spring column.

[0011] The fertilization assembly also includes a feed pipe and a conveying rigid pipe. The feed pipe is connected to the middle of the fertilization ring, and the conveying rigid pipe is connected to the bottom of the fertilizer box. The conveying rigid pipe is inclined. One end of the conveying rigid pipe away from the fertilizer box is connected to a corrugated hose, and the other end of the corrugated hose is connected to a rotary joint. One end of the rotary joint is connected to the feed pipe.

[0012] Inside the fertilizer tank, a stirring rod is rotatably mounted via bearings. One end of each of the two sets of stirring rods passes through the interior of the two fertilizer tanks. The two sets of stirring rods are connected by a transmission rod. A stirring motor is mounted on the trolley, and a bevel gear set is provided between the output end of the stirring motor and the transmission rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by controlling the two sets of fertilization rings to approach each other, the discharge channels of the two sets of fertilization rings can be automatically opened, and with the two approaching each other to form a relatively complete circular fertilization ring, the trees can be fertilized in a ring, so that the fertilizer is relatively evenly covered on the outer periphery of the seedling root system, improving the matching effect between the fertilizer distribution and the natural distribution of the seedling root system, and reducing the defects of the strip coverage of traditional linear fertilization.

[0014] The fertilization unit allows for quick control of the two sets of fertilization rings to move closer or further apart, and the trolley can be used to quickly place seedlings into and remove them from the two sets of fertilization rings, preparing them for the next fertilization of other seedlings.

[0015] By linking the bevel gear set at the output end of the stirring motor, the transmission rod can be driven to rotate, which in turn drives the two sets of stirring rods to rotate inside the fertilizer tank. This stirs the fertilizer inside the fertilizer tank, reducing the blockage of subsequent pipelines caused by large fertilizer particles and promoting the flow of fertilizer, allowing the fertilizer to enter the fertilization ring more smoothly.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, as Figures 1-6 As shown, a fertilization device for forest seedling cultivation includes a trolley 1, which serves as the moving carrier of the device. A fertilizer box 2 is symmetrically installed at one end of the trolley 1 for storing fertilizer. A box cover 3 is provided on the top of the fertilizer box 2 to close the top opening of the fertilizer box 2 and reduce the entry of impurities or the overflow of fertilizer. An adjusting bracket 4 is fixedly connected to the end of the trolley 1 away from the fertilizer box 2. A connecting frame 5 is slidably connected to both ends of the adjusting bracket 4. A fertilizer ring 6 is connected to one end of the connecting frame 5.

[0027] The fertilizer application component is mounted on the trolley 1 and is used in conjunction with the fertilizer application ring 6.

[0028] Example 2, as Figures 1-5 As shown, the fertilizer application assembly includes a lead screw 7, a servo motor 8, and a second slider 10. The servo motor 8 is installed at one end of the adjustment bracket 4. The lead screw 7 is rotatably installed inside the adjustment bracket 4, and one end of it is connected to the output end of the servo motor 8. The lead screw 7 is connected to a first slider 9 via a lead screw nut pair. One end of the first slider 9 is fixedly connected to the connecting frame 5. The second slider 10 is fixedly connected to both ends of the connecting frame 5. The second slider 10 is slidably connected to the adjustment bracket 4.

[0029] like Figures 1-5 As shown, the fertilization assembly also includes a limiting frame 11 and a retaining ring 12. The limiting frame 11 is fixed inside the fertilization ring 6, and the retaining ring 12 slides through the inside of the fertilization ring 6. A push rod 13 is fixedly connected to the end of the fertilization ring 6. One end of the push rod 13 passes through the limiting frame 11 and the inside of the fertilization ring 6. A return spring 26 is provided between the limiting frame 11 and the retaining ring 12. One end of the return spring 26 is fixedly connected to the retaining ring 12.

[0030] like Figures 1-5 As shown, the fertilization assembly also includes a first trapezoidal slider 14 and a spring post 16. The first trapezoidal slider 14 is fixedly connected to one end of the push rod 13 away from the inside of the fertilization ring 6. The inclined surface of the first trapezoidal slider 14 is slidably connected to a second trapezoidal slider 15. The fixed end of the spring post 16 is fixedly connected to the surface of the fertilization ring 6. The movable end of the spring post 16 is connected to one end of the second trapezoidal slider 15. A push plate 17 is installed at the end of the second trapezoidal slider 15 away from the spring post 16.

[0031] like Figures 1-5As shown, the fertilization assembly also includes a feed pipe 18 and a conveying rigid pipe 21. The feed pipe 18 is connected to the middle of the fertilization ring 6, and the conveying rigid pipe 21 is connected to the bottom of the fertilizer box 2. The conveying rigid pipe 21 is inclined, and its inclination angle conforms to the principle of gravity flow. The end of the conveying rigid pipe 21 away from the fertilizer box 2 is connected to a corrugated hose 20, and the other end of the corrugated hose 20 is connected to a rotary joint 19. One end of the rotary joint 19 is connected to the feed pipe 18.

[0032] During operation, the device can be easily and quickly moved to the designated location using the trolley 1. Due to factors such as the growth environment of forest seedlings, the device will vibrate due to road bumps during the movement of the trolley 1. This vibration will promote the flow of fertilizer. In conjunction with the inclined setting of the conveying rigid pipe 21, the fertilizer can smoothly enter the fertilizer ring 6 from the fertilizer box 2, the conveying rigid pipe 21 and the corrugated hose 20.

[0033] During fertilization, the output of the servo motor 8 rotates forward, which in turn drives the lead screw 7 to move the two sets of fertilization rings 6 away from each other via the two sets of connecting frames 5. At this time, simply move the trolley 1 to place the seedling between the two sets of fertilization rings 6, and rotate the output of the servo motor 8 in the opposite direction. With the help of the lead screw 7 and connecting frames 5, the two sets of fertilization rings 6 can be controlled to move closer to each other. During this process, when the two sets of fertilization rings 6 are close to each other, the two sets of push plates 17 squeeze each other, which in turn pushes the second trapezoidal slider 15 to compress the moving end of the spring column 16 towards its fixed end. As the process continues, the first trapezoidal slider 14 is pushed by the inclined surface of the second trapezoidal slider 15, and guided by the push rod 13, the retaining ring 12 is pushed towards the cart 1. This prevents the fertilizer discharge channel at the end of the fertilizer ring 6 near the cart 1 from being blocked, allowing the fertilizer to be continuously discharged through the discharge channel. This circular fertilization of the trees achieves a relatively uniform coverage of the fertilizer around the seedling roots, improving the matching effect between the fertilizer distribution and the natural distribution of the seedling roots, and reducing the defects of the strip-shaped coverage of traditional linear fertilization.

[0034] After fertilization is completed, simply control the output of the servo motor 8 to rotate in the forward direction. The two sets of fertilization rings 6 can be controlled to move away from each other through the lead screw 7 and the connecting frame 5. During this process, under the elastic force of the spring column 16, the second trapezoidal slider 15 is pushed to reset, and under the elastic force of the reset spring 26, the retaining ring 12 and the push rod 13 are pulled to reset. At this time, the retaining ring 12 blocks the discharge channel to prevent fertilizer from being discharged randomly through the discharge channel and to prepare for the next fertilization of other seedlings.

[0035] In summary, by controlling the two sets of fertilization rings 6 to move closer to each other, the discharge channels of the two sets of fertilization rings 6 can be automatically opened. With the two sets of fertilization rings 6 moving closer together, a relatively complete circular fertilization ring 6 can be formed, which can achieve circular fertilization of trees. This allows the fertilizer to be covered relatively evenly around the seedling roots, improving the matching effect between the fertilizer distribution and the natural distribution of the seedling roots, and reducing the defects of the strip-shaped coverage of traditional linear fertilization.

[0036] The fertilization assembly allows for quick control of the two sets of fertilization rings 6 to move closer or further apart, and the trolley 1 allows for quick placement of seedlings into the two sets of fertilization rings 6 and quick removal of seedlings from the two sets of fertilization rings 6, preparing for the next fertilization of other seedlings.

[0037] Example 3, as Figure 1 , Figure 6 As shown, a stirring rod 22 is rotatably mounted inside the fertilizer tank 2 via a bearing. One end of each of the two sets of stirring rods 22 passes through the interior of the two sets of fertilizer tanks 2. The two sets of stirring rods 22 are connected by a transmission rod 23. A stirring motor 25 is mounted on the trolley 1. A bevel gear set 24 is provided between the output end of the stirring motor 25 and the transmission rod 23.

[0038] During operation, the transmission rod 23 can be driven to rotate by the bevel gear set 24 linked to the output end of the stirring motor 25. This, in turn, drives the two sets of stirring rods 22 to rotate inside the fertilizer tank 2, and stirs the fertilizer inside the fertilizer tank 2. This reduces the blockage of subsequent pipelines caused by large fertilizer particles, and promotes the flowability of fertilizer, allowing the fertilizer to enter the fertilization ring 6 more smoothly.

[0039] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
