Description

Technical Field

[0001] This invention relates to the field of landscaping maintenance, and in particular to an energy-saving landscaping construction and fertilization device. Background Technology In the process of landscaping construction, irrigation and fertilization of saplings during the early stages, along with pre-planting soil treatment and irrigation, are crucial for ensuring sapling survival and subsequent growth. Currently, the fertilization and irrigation devices used in landscaping construction have many technical limitations in actual operation, making it difficult to meet the demands for refined and energy-efficient construction. Firstly, existing equipment mostly relies on fixed tracks or manual dragging, making it difficult to flexibly adjust the work points according to the distribution of saplings or the land pretreatment area. Especially in scenarios where multiple saplings are scattered, the work efficiency is low and the intensity of manual operation is increased.

[0002] Secondly, the root distribution range of saplings during the sapling stage is highly correlated with the trunk diameter. Existing devices cannot accurately plan the fertilization and irrigation range for saplings of different diameters or different pre-treated land areas. This often results in fertilization areas deviating from the active root zone and uneven fertilizer distribution, leading to fertilizer waste. Furthermore, local nutrient excess or deficiency can easily affect sapling growth. For land before planting, it is also impossible to plan suitable irrigation and fertilization trajectories in advance based on the preset diameter of the saplings to be planted. After the saplings are planted, secondary adjustments are required, increasing construction costs.

[0003] Third, loosening the soil before fertilization is an important prerequisite for improving fertilizer absorption efficiency. However, existing equipment lacks an effective detection mechanism for obstacles (such as stones, bricks, weed roots, etc.) in the working area before loosening the soil. When the loosening components come into direct contact with obstacles, they are prone to wear and even damage, which not only affects the quality of loosening the soil, but also requires stopping the machine for manual cleaning.

[0004] Fourth, it is impossible to dynamically adjust irrigation parameters based on soil hardness. The soil texture varies significantly across different garden plots. For example, clay areas have high soil hardness and difficulty in water penetration, while sandy areas have low soil hardness and water is easily lost through rapid infiltration. Existing devices mostly use fixed spray volume and flow parameters. In clay areas, this can lead to problems such as water failing to penetrate deep into the root system and fertilizer being difficult to dissolve and absorb. In sandy areas, it can cause water and fertilizer to be quickly lost with the water flow, reducing water and fertilizer utilization efficiency and resulting in serious waste of water and fertilizer resources. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving landscaping fertilization device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving landscaping fertilization device includes a base with casters rotatably mounted at the four corners of the base via bearings. A fertilization box is fixedly mounted on the top of the base. A measuring component for detecting the circumference diameter of the fertilized area is also fixedly mounted on the top of the base.

A fourth lead screw slide is fixedly mounted vertically at the bottom of the slider on the third lead screw slide. The slider on the fourth lead screw slide is fixedly connected to the arc-shaped plate.

[0009] Preferably, the detection components are provided in multiple sets, all of which are fixedly connected to the bottom of the arc-shaped plate. The multiple sets of detection components are evenly arranged along the circumference of the arc-shaped plate. Each detection component includes a second electric push rod, a second motor, a fixed cylinder, and a conical insert. The arc-shaped plate has multiple slots through which the second electric push rod is fixed. The output end of the second electric push rod is fixedly connected to the second motor, and the output end of the second motor is connected to the inside of the fixed cylinder. The conical insert is slidably disposed within the fixed cylinder by a spring and extends out of the fixed cylinder. A pressure sensor for detecting the position of the conical insert is fixedly provided on the inner wall of the fixed cylinder.

[0010] Preferably, the number of automatic sensing components is the same as the number of detection components, and the automatic sensing components are fixedly connected to the conical insert. The automatic sensing components include a first cylindrical plate, a second cylindrical plate, a loosening hoe blade, a torque spring, a sector plate, a nozzle pipe, and a connecting plate. The first cylindrical plate and the second cylindrical plate are rotatably connected to the surface of the conical insert via bearings, and a torque spring is fixedly provided between the first cylindrical plate and the second cylindrical plate. The number of loosening hoe blades is multiple and fixedly connected along the circumference of the first cylindrical plate. The sector plate is fixedly connected to the second cylindrical plate and abuts against the bottom of the nozzle pipe. The connecting plate has through holes for the fixed cylinder and the nozzle pipe to pass through.

[0011] Preferably, the scraping assembly includes a protruding plate, a support plate, a housing, two vertical plates, a third motor, a rotating rod, a scraping head, and a baffle. There are two protruding plates. The two side walls of the fourth lead screw slide are fixedly connected to the protruding plates. A fifth lead screw slide is fixedly mounted on one side wall of one protruding plate, and a horizontal plate is fixedly connected to one side wall of the other protruding plate. A slider on the fifth lead screw slide is fixedly connected to one of the vertical plates. A groove is provided on the horizontal plate for the other vertical plate to slide. A connecting rod is fixedly connected to the top of the two vertical plates, and the two vertical plates are rotatably connected to the rotating rod via bearings. The third motor is fixedly connected to one side wall of one of the vertical plates, and its output end is fixedly connected to the rotating rod. The scraping head is fixedly connected to the rotating rod. The horizontal plate and the fifth lead screw slide are fixedly connected to the support plate.

The baffle is fixedly connected to the horizontal plate and one side wall of the fifth lead screw slide, and multiple casters are rotatably mounted on the bottom of the baffle via bearings.

[0012] The present invention has the following beneficial effects: This device uses detection components to accurately locate and measure the diameter of the trunk of saplings or the irrigation area of ​​the land before planting. Based on the measurement results, it plans a circular fertilization trajectory to ensure that the fertilization range is highly matched with the active root area of ​​the sapling or the pre-set root distribution area of ​​the seedlings to be planted in the land. This avoids the fertilizer deviating from the effective absorption area, reduces fertilizer waste, and ensures that the fertilizer is evenly distributed in the working area, providing balanced nutrients for the growth of saplings or the subsequent planting of seedlings.

[0013] Before loosening the soil, this device uses a detection component to identify obstacles in the work area in advance, and then the removal component automatically removes the obstacles without human intervention. This avoids wear or damage caused by the loosening component directly contacting the obstacles, ensuring the continuity and stability of the loosening operation. The soil after removing obstacles is more easily loosened, improving soil permeability and creating a good soil environment for subsequent irrigation and fertilization, further improving fertilizer absorption efficiency.

[0014] This device uses an automatic sensing component to sense soil hardness in real time after the soil loosening component is inserted into the soil and adjusts the size of the spray nozzle accordingly. When facing soil with high hardness (such as clay), the nozzle automatically increases to promote water penetration into deeper soil layers and ensure that water and fertilizer can reach the root zone; when facing soil with low hardness (such as sandy soil), the nozzle automatically decreases to avoid water and fertilizer loss caused by rapid water infiltration.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Refer to Figure 1 - Figure 6The system includes a base 1, with universal wheels at the four corners of the bottom of the base 1 that rotate via bearings. A fertilizer box 2 is fixedly mounted on the top of the base 1.

Two measuring rods 32 are provided and symmetrically mounted on the sliders of the reciprocating screw slide. A second screw slide is also provided on the top of the base 1.

[0019] In this embodiment: check the status of each component of the device to ensure that the fertilizer box 2 contains sufficient fertilizer and that the casters, electrical components and other parts are operating normally; determine the location of the saplings to be planted or the land pretreatment area before planting according to the needs of landscaping construction. The operator pushes the base 1 and moves the device to the target work point using the bottom casters; the reciprocating screw slide of the measuring component 3 is activated, and the slide slider drives the two measuring rods 32 to move synchronously in the horizontal direction until the two measuring rods 32 respectively fit against the two sides of the sapling trunk (or the circumferential boundary of the pre-set irrigation area of ​​the land). The reciprocating screw slide stops running, and the measured diameter data is recorded to complete the diameter positioning of the fertilization trajectory. Based on the measured diameter data, the movement parameters of the second screw slide are preset, and the second screw slide is activated. The slide slider drives the fertilization mechanism 4 to move as a whole, so that the center of the fertilization mechanism 4 is aligned with the center of the measured circular fertilization trajectory, ensuring that the subsequent operation range accurately covers the target area. Example 2:

The output end of the second electric push rod 421 is fixedly connected to the second motor 422. The output end of the second motor 422 is connected to the inside of the fixed cylinder 423. The conical insert 424 is slidably set inside the fixed cylinder 423 by a spring and extends out of the inside of the fixed cylinder 423. A pressure sensor for detecting the position of the conical insert 424 is fixedly provided on the inner wall of the fixed cylinder 423.

[0024] The number of automatic sensing components 43 is the same as that of detection components 42, and the automatic sensing components 43 are fixedly connected to the conical insert 424. The automatic sensing components 43 include a first cylindrical plate 431, a second cylindrical plate 432, a soil loosening blade 433, a torque spring 434, a sector plate 435, a nozzle pipe 436, and a connecting plate 437. The first cylindrical plate 431 and the second cylindrical plate 432 are rotatably connected to the surface of the conical insert 424 through bearings, and a torque spring 434 is fixedly provided between the first cylindrical plate 431 and the second cylindrical plate 432. The number of soil loosening blades 433 is provided and they are fixedly connected along the circumference of the first cylindrical plate 431. The sector plate 435 is fixedly connected to the second cylindrical plate 432 and abuts against the bottom of the nozzle pipe 436. The connecting plate 437 has holes through which the fixing cylinder 423 and the nozzle pipe 436 pass.

[0025] The scraping assembly 44 includes a protruding plate 441, a support plate 442, a housing 443, two vertical plates 444, a third motor 445, a rotating rod 446, a scraping head 447, and a baffle 448. Two protruding plates 441 are provided. The two side walls of a fourth lead screw slide are fixedly connected to the protruding plates 441. A fifth lead screw slide is fixedly mounted on one side wall of one protruding plate 441, and a horizontal plate 449 is fixedly connected to one side wall of the other protruding plate 441. A slider on the fifth lead screw slide is fixedly connected to one vertical plate 444. A groove is provided on the horizontal plate 449 for the other vertical plate 444 to slide. The tops of the two vertical plates 444 are fixedly connected by a connecting... The rod 4410 is rotatably connected to the two vertical plates 444 via bearings and the rotating rod 446. The third motor 445 is fixedly connected to one side wall of one of the vertical plates 444 and its output end is fixedly connected to the rotating rod 446. The scraping head 447 is fixedly connected to the rotating rod 446. The horizontal plate 449 is fixedly connected to the fifth screw slide and the support plate 442. The top of the support plate 442 is fixedly connected to the box 443. The box 443 is connected to each nozzle pipe 436 via a telescopic pipe. The baffle 448 is fixedly connected to the horizontal plate 449 and one side wall of the fifth screw slide, and the bottom of the baffle 448 is provided with multiple universal wheels that rotate via bearings.

[0026] In this embodiment: the first motor 414 of the loosening component 41 is activated, and the output end of the first motor 414 drives the movable block 415 to slide along the groove at the bottom of the circular frame box 413 through gear transmission; at the same time, the third screw slide (horizontal) and the fourth screw slide (vertical) at the bottom of the movable block 415 are activated to adjust the horizontal position and height of the arc plate 416 so that the arc plate 416 fits the circumferential direction of the circular fertilization trajectory; after the arc plate 416 is in place, the second electric push rod 421 of the detection component 42 is activated, and the output end of the second electric push rod 421 pushes the second motor 422, the fixed cylinder 423 and the conical insert 424 to move down until the conical insert 424 is close to the soil surface.

[0027] Obstacle detection: The second motor 422 is activated, and its output drives the fixed cylinder 423 and the conical rod 424 to rotate. During rotation, the conical rod 424 gradually inserts into the soil. If the conical rod 424 does not contact the obstacle, it smoothly drills into the soil, and the spring inside the fixed cylinder 423 remains slightly compressed, so the pressure sensor will not reach the threshold for triggering the obstacle. If the conical rod 424 contacts the obstacle, the obstacle generates a reverse resistance on the conical rod 424, and the conical rod 424 compresses the spring inside the fixed cylinder 423. The pressure sensor detects the displacement and pressure increase of the conical rod 424, generates an obstacle signal, and feeds it back to the device control system, determining that an obstacle exists at the corresponding location.

[0028] Positioning of the removal component 44: After receiving the obstacle signal, the control system activates the third screw slide of the removal component 44. The slider of the third screw slide drives one side of the vertical plate 444 to move horizontally, while the other side of the vertical plate 444 slides synchronously along the groove of the horizontal plate 449 until the rotating rod 446 and the removal head 447 move directly above the obstacle. At the same time, the height of the vertical plate 444 is adjusted according to the burial depth of the obstacle (through the vertical adjustment function of the third screw slide or the additional electric push rod) so that the removal head 447 is close to the soil surface where the obstacle is located.

[0029] Obstacle removal and collection: Start the third motor 445. The output of the third motor 445 drives the rotating rod 446 to rotate. The rotating rod 446 drives the shovel head 447 to rotate and drill into the soil to dig out the obstacle. After the obstacle is dug out, the height of the shovel head 447 can be adjusted by controlling the fifth lead screw slide. During the shoveling process, the flying obstacles will be blocked by the baffle 448 and will fall down along the baffle 448, and will not fly to other positions.

[0030] Loosening component 41 in place: After the obstacle is cleared, the second electric push rod 421 of the detection component 42 is activated. The output end of the second electric push rod 421 pushes the second motor 422, the fixed cylinder 423 and the conical insert 424 to move down until the conical insert 424 is close to the soil surface. The loosening hoe blade 433 of the automatic sensing component 43 is close to the soil surface, and the second motor 422 is activated. The output end of the second motor 422 drives the loosening hoe blade 433 to rotate. The loosening hoe blade 433 gradually inserts into the soil during the rotation. After the loosening is completed, after the loosening of a certain area is completed, the first motor 414 is activated again. The position of the movable block 415 is adjusted through gear transmission. The angle of the arc plate 416 is adjusted in conjunction with the first and second screw slides to ensure that the loosening hoe blade 433 is evenly distributed in the circumferential area of ​​the circular fertilization trajectory.

[0031] Soil hardness sensing and water volume adjustment: When the loosening blade 433 rotates to loosen the soil, if it encounters hard soil, the resistance of the soil to the loosening blade 433 increases, causing the first cylindrical plate 431 to rotate relative to the second cylindrical plate 432, compressing the torque spring 434 between them; the force generated by the deformation of the torque spring 434 causes the second cylindrical plate 432 to rotate, and the second cylindrical plate 432 causes the sector plate 435 to rotate synchronously. The sector plate 435 generates a thrust on the bottom of the nozzle pipe 436, which increases the diameter of the nozzle pipe 436. The increased water volume ensures that water can penetrate deep into hard soil. If encountering soft soil, the resistance of the soil to the loosening blade 433 decreases, the torque spring 434 resets, and drives the second cylindrical plate 432 and the sector plate 435 to rotate in the opposite direction. The thrust of the sector plate 435 on the nozzle pipe 436 decreases, the diameter of the nozzle pipe 436 shrinks, reducing the water volume and preventing water from seeping away too quickly. The entire adjustment process is achieved through the mechanical deformation of the torque spring 434, without the need for additional electronic control adjustment, ensuring energy saving and stability.

[0032] When the feeding component (such as a micro pump) of fertilizer box 2 is activated, the fertilizer in fertilizer box 2 is transported to box body 443 through telescopic pipe; inside box body 443, water is transported to nozzle pipe 436 through components such as water pump telescopic pipe, and fertilizer and water are mixed in nozzle pipe 436 to form water-fertilizer mixture.

[0033] The water-fertilizer mixture is evenly sprayed into the circular fertilization area after the soil has been loosened, through the adjusted diameter of the nozzle pipe 436; during the spraying process, it is evenly sprayed along the set circumferential direction, and the spray volume is automatically adjusted during the spraying process.

[0034] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
