Description

Technical Field

[0001] This invention relates to the field of seedling fertilization technology, specifically to a fertilization device for landscape seedlings. Background Technology

[0002] In the cultivation and maintenance of landscape seedlings, fertilization is a key link to ensure the healthy growth of seedlings. At present, most traditional seedling fertilization methods rely on manual experience, and staff fertilize different seedlings based on subjective judgment. This fertilization method is not only inefficient and difficult to meet the maintenance needs of large-scale landscape seedlings, but also lacks precision and cannot reasonably control the amount of fertilizer and the fertilization area according to the actual growth status and root distribution of the seedlings.

[0003] While some existing fertilization equipment possesses certain automation capabilities, it also exhibits significant limitations. On one hand, these devices cannot automatically adjust the amount and range of fertilizer application based on the root characteristics of seedlings with different diameters, resulting in fertilizer failing to accurately cover the area around the seedling roots and easily leading to fertilizer waste or insufficient fertilization. On the other hand, existing fertilization equipment has poor versatility, often requiring the replacement of specialized equipment or complex parameter settings for different sizes of seedlings, making operation cumbersome and unable to meet the diverse fertilization needs of seedlings in landscape gardens. Summary of the Invention

[0004] The purpose of this invention is to provide a fertilization device for landscape seedlings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fertilization device for landscape seedlings, comprising a moving device, a detection device, a feeding device, and a fertilization device. The moving device is used for transportation by workers. The detection device is located at the top end of the moving device and extends to the center of the moving device, and is capable of detecting the diameter of the seedlings. The feeding device is located at the top of the detection device and is capable of storing and feeding fertilizer. The feeding device can feed fertilizer based on the diameter detection of the seedlings detected by the detection device. The fertilization device is located at the bottom of the detection device and can control the area of ​​fertilization on the seedlings by controlling the amount of fertilizer fed by the feeding device.

[0006] Preferably, in order to move the device to the trunk of the sapling, the moving device includes a first connecting rod, a support plate, a push rod, a chassis frame, and wheels.

[0008] Preferably, for material feeding in conjunction with the detection device, the feeding device includes a rectangular block, a groove, a moving groove, a first rectangular plate, a corner plate, a moving block, a second connecting rod, a short rod, a long rod, and a storage hopper. The rectangular block is disposed at the top of the feeding pipe, and the top surface of the rectangular block has a vertically penetrating groove. The outer wall of the rectangular block has a horizontally penetrating moving groove, which intersects and communicates with the groove. The storage hopper is disposed at the center of the top surface of the rectangular block, and the inner cavity of the storage hopper extends into the groove. The first rectangular plate is disposed on the rear side of the outer wall of the rectangular block. The corner plate is disposed at the top of the rear side of the outer wall of the rectangular block, and is a certain distance away from the top surface of the rectangular block. There are two moving blocks, which are respectively disposed at the left and right ends of the moving groove, and one side of the outer wall of the two moving grooves is in contact with each other. There are two second connecting rods, which are respectively disposed on the other side of the outer wall of the two moving blocks. The short rod is disposed at one end of one of the second connecting rods. The long rod is disposed at one end of the other second connecting rod. The driving assembly is disposed at one end of the short rod and the long rod.

[0009] Preferably, in order to cooperate with the detection device for material feeding, the drive assembly includes a rack, a gear, and a DC motor. There are two racks, which are respectively disposed at one end of the short rod and the long rod. The gear is disposed at the center of the top surface of the first rectangular plate through a bearing, and the gear meshes with the two racks. The DC motor is disposed on the top surface of the inner wall of the corner plate, and the output end of the DC motor is connected and fixed to the top surface of the gear.

[0010] Preferably, the rotation of the gear drives the two racks to move in opposite directions, thereby driving the two moving blocks to open or close via the short rod and the long rod respectively.

[0011] Preferably, to coordinate the amount of material fed by the feeding device with the size of the fertilization range for the seedlings, the fertilization device includes a second rectangular plate, a first concave plate, a first chute, a second concave plate, a first long plate, a second chute, a third chute, a second long plate, a slider, a connecting block, a brake motor, and a rotating plate. The second rectangular plate is disposed on the bottom surface of the sensor; four first concave plates are respectively disposed at the four ends of the outer wall of the rectangular plate, and one end of each of the four first concave plates is provided with a first chute; four second concave plates are respectively embedded in the four first chutes and can be limited to move along the inner wall of the first chute; four first long plates are respectively disposed on the bottom surface of the four first concave plates, and the outer wall of each of the four first concave plates is provided with a first chute. Each end of the first concave plate is provided with a second sliding groove, and the bottom surface of the outer wall of each of the four first concave plates is provided with a third sliding groove that runs vertically through the plate. There are four second long plates, which are respectively embedded in the four second sliding grooves and can move along the inner wall of the second sliding groove. There are four sliders, which are respectively set at one end of the bottom surface of the four second long plates and are respectively set in the four third sliding grooves. A connecting block is set at one end of the connecting block and the other end of the second long plate. The brake motor is set at the center of one end of the top surface of the chassis frame. A rotating plate is set at the output end of the brake motor. The top surface of the rotating plate is provided with four equidistant arc-shaped grooves that run vertically through the plate, and four movable sliders are respectively set in the end of the four arc-shaped grooves near the center of the rotating plate.

[0012] Preferably, the brake motor drives the brake motor to rotate and drive the four sliders to move within the third slide groove through the four arc-shaped grooves. This drives the four sliders to move the second concave plates within the four first slide grooves through the connecting blocks, thereby driving the four second concave plates to expand their area.

[0013] This invention provides a fertilization device for landscape seedlings, which has many significant beneficial effects and effectively solves many problems existing in traditional seedling fertilization methods, as follows: 1. Precise linkage between diameter detection and fertilizer dispensing: The sensor in the detection device can accurately measure the diameter of the seedling trunk. Based on the detection data, the DC motor automatically adjusts the rotation speed and drives the gear and rack mechanism to control the opening and closing degree of the moving block, thereby achieving precise control of the fertilizer dispensing amount. For example, when the seedling diameter is small, the moving block opens less, reducing the amount of fertilizer dispensed; when the diameter is large, the amount of fertilizer dispensed is increased, so that the amount of fertilizer applied matches the growth needs of the seedling, avoiding the impact of insufficient or excessive fertilization on seedling growth.

[0014] 2. Adaptive Adjustment of Fertilization Area: The fertilization device uses a brake motor to drive a rotating plate and an arc-shaped groove, which in turn drives the slider and connecting block to automatically adjust the unfolded area of ​​the four second concave plates according to the amount of material fed. The larger the diameter of the seedling and the wider the root distribution, the larger the fertilization area should be, ensuring that the fertilizer evenly covers the area around the roots and improving nutrient absorption efficiency. Compared with the traditional "one-size-fits-all" fertilization method, this significantly improves the accuracy and effectiveness of fertilization.

[0015] 3. Reduced Manual Intervention and Reliance on Experience: Traditional fertilization relies on subjective human judgment, which is inefficient and easily affected by human factors. This device, through automated components such as sensors and motors, automates the entire process from diameter detection and material feeding control to fertilization area adjustment, significantly reducing the intensity of manual operation. It is especially suitable for large-scale garden seedling maintenance, significantly improving work efficiency and saving labor costs. The device does not require changing to special equipment or making complex parameter settings for different seedling sizes. The staff only needs to push the moving device to bring the seedling into the detection area, and the system can automatically complete the detection and adjustment. The operation is convenient and smooth, greatly shortening the fertilization time for a single seedling and improving the overall work efficiency.

[0016] 4. Universal for multiple seedling sizes: Through the linkage adjustment mechanism of the detection device and the feeding and fertilization device, the device can adapt to the root system characteristics of different diameters (from small seedlings to large seedlings), realize universal fertilization of "one set of equipment for multiple seedlings", break through the limitation of existing equipment requiring special configuration, and meet the maintenance needs of diverse seedlings in landscape gardens.

[0017] 5. Precise control of fertilizer application and adjustment of fertilization area ensures that fertilizer is concentrated in the effective absorption area of ​​the seedling roots, avoiding fertilizer loss or waste due to improper fertilization. Compared with traditional manual fertilization, it can save more than 30% of fertilizer usage, reducing maintenance costs and potential environmental pollution. By combining sensor detection, motor drive and mechanical transmission technology, it provides an intelligent solution for fertilization of garden seedlings. Its innovative linkage adjustment mechanism and automated operation mode can effectively promote the development of landscape garden maintenance towards precision and intelligence.

[0018] In summary, this device, through multiple innovations such as precise detection, automatic adjustment, and structural optimization, comprehensively improves the quality and efficiency of seedling fertilization. It is versatile, convenient, and economical, and can be widely used in various landscape garden seedling maintenance scenarios, demonstrating significant practical value and market potential.

[0027] As a preferred option, further, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the fertilizer applicator 4 includes a second rectangular plate 41, a first concave plate 42, a first chute 43, a second concave plate 44, a first long plate 45, a second chute 46, a third chute 47, a second long plate 48, a slider 49, a connecting block 410, a brake motor 411, and a rotating plate 412. The second rectangular plate 41 is disposed on the bottom surface of the sensor 25. There are four first concave plates 42, which are respectively disposed at the four ends of the outer wall of the rectangular block 31. The concave shape of the first concave plates 42 is used to prevent the round fertilizer from falling to other places during the rolling output. One end of each of the four first concave plates 42 is provided with a first chute 43. There are four second concave plates 44, which are respectively embedded in the four first chute 43. The first long plate 45 is provided at one end of the outer wall of the first concave plate 42, and the second concave plate 44 is concave to prevent the round fertilizer from falling to other places during rolling output, thus concentrating the fertilizer application. A second groove 46 is provided at one end of the outer wall of each of the four first concave plates 42, and a third groove 47 is provided on the bottom surface of the outer wall of each of the four first concave plates 42. The second long plate 48 is provided at one end of the four second grooves 46, and can be moved along the inner wall of the second groove 46. The slider 49 is provided at one end of the bottom surface of each of the four second long plates 48, and the four sliders 49 are respectively... The four third sliding grooves 47 are arranged in the middle; the connecting block 410 is arranged at one end of the connecting block 44 and the other end of the second long plate 48. The connecting block 410 is used for the second long plate 48 to drive the second concave plate 44, so that the second long plate 48 drives the second concave plate 44 to move in a limited position; the brake motor 411 is arranged at the center of one end of the top surface of the chassis frame 14.

Four movable sliders 49 are respectively arranged in one end of the arc-shaped groove 413 near the center of the rotating plate 412. The rotating plate 412 drives the four arc-shaped grooves 413 to rotate, which can move the sliders 49 at one end of the arc-shaped groove 413 to the other end of the arc-shaped groove 413. At the same time, the four sliders 49 are limited to a certain position. The brake motor 411 drives the brake motor 412 to rotate and drive the four sliders 49 to move in the third slide groove 47 through the four arc-shaped grooves 413. This drives the four sliders 49 to drive the second concave plate 44 to move in the four first slide grooves 43 through the connecting block 410, thereby driving the area of ​​the four second concave plates 44 to expand.

[0028] The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process. The specific operation is as follows: the worker pours the round fertilizer into the storage hopper 313, and the worker holds two push rods 13 to make the seedling trunk enter the concave rod 24. The diameter of the seedling trunk is detected by two sensors 25. Based on the detection, the DC motor 312 is driven to rotate, which drives the two racks 310 to move and drive the moving block 36 to open for feeding. At the same time, the sensor 22 detects the amount of fertilizer during feeding, which drives the brake motor 411 to drive the rotating plate 412 to rotate. Through the four arc grooves 413, the sliders 49 are driven to expand the area of ​​the four second concave plates 44 to a large or small size. The round fertilizer enters the material distribution funnel 26 and is evenly distributed to the four output pipes. The round fertilizer rolls through the slope of the four output pipes into the four first concave plates 42 and is output outward from the second concave plates 44 to fertilize the seedlings. It can adjust the size of the fertilization area for different seedling diameters and improve the fertilization quality of seedlings of different diameters.

[0029] In summary, this invention uses the sensor 25 in the detection device 2 to accurately detect the diameter of the seedlings. Based on the detection results, the DC motor 312 can automatically adjust its rotation speed to control the amount of fertilizer dispensed by the feeding device 3. Smaller seedling diameters require less fertilizer, while larger diameters require more. Simultaneously, the fertilization device 4 can precisely control the fertilization area based on the amount of fertilizer dispensed, using components such as the brake motor 411 and the rotating plate 412. Larger seedling diameters result in larger root areas, leading to a correspondingly larger fertilization area, ensuring that fertilizer can reasonably cover the area around the seedling roots. Compared to traditional fertilization methods, this significantly improves the accuracy and quality of fertilization, avoids fertilizer waste, enhances fertilization effectiveness, and ensures that seedlings of different diameters receive appropriate nutrient supply.

[0030] It can be applied to seedlings of different diameters, whether small or large, and can achieve precise fertilization through automatic detection and adjustment. There is no need to change equipment or make complicated parameter settings for different seedlings, which expands the application range of the device and meets the fertilization needs of diverse seedlings in landscape gardens.
