Description

Technical Field

[0001] The present invention relates to the technical field of landscaping construction, and particularly to a fertilizer spreading device for landscaping project construction. Background Art

[0002] In landscaping project construction, when fertilizing smaller plants, special attention needs to be paid to the accuracy and uniformity of fertilization. Since the root systems of small plants are relatively fragile and have a limited distribution range, the accuracy of the fertilizer spreading position is crucial. If fertilizer particles are directly spread near the roots of the plants, it may burn the roots due to excessive concentration and affect the growth of the plants; while if the fertilization position is too far away, it may cause the fertilizer to not be effectively absorbed by the roots and reduce the fertilization effect.

[0003] In addition, the use of fertilizing devices in loose soil also poses challenges. The granular structure of loose soil is unstable, and fertilizer particles are likely to be unevenly distributed due to the fluidity of the soil. In this case, the fertilizing device needs to have good discharge control ability to ensure that the fertilizer can be evenly spread around the plants. However, most of the existing fertilizing devices adopt a fixed discharge port design and cannot flexibly adjust the fertilization radius according to the size of the plants and soil conditions, resulting in uneven fertilizer spreading and affecting the growth effect of the plants.

[0004] At the same time, when the existing devices spread fertilizer, the fertilizer particles may be concentrated in a certain area while there is insufficient fertilizer in other areas. This uneven fertilization method not only wastes fertilizer resources but also may lead to uneven growth of the plants. Therefore, a fertilizing device that can flexibly adjust the fertilization radius according to the size of the plants and soil conditions and can achieve annular uniform discharge is needed to meet the fertilization requirements of small plants in loose soil. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a fertilizer spreading device for landscaping project construction, which solves the problems presented in the background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A fertilizer spreading device for landscaping project construction, comprising:

[0007] A handle;

[0008] A storage mechanism, which is installed at the bottom of the handle, and the storage mechanism is used for storing granular fertilizer;

[0009] A metering mechanism, located at the bottom of the storage mechanism, and the metering mechanism is used for controlling the discharge of granular fertilizer;

[0010] An adjusting mechanism, which is installed at the bottom of the metering mechanism, and the adjusting mechanism is used for adjusting the size of the fertilization radius;

[0011] The discharging mechanism is communicated with the metering mechanism, and the discharging mechanism is used to cooperate with the metering mechanism to realize the fertilizer discharging work.

[0012] Preferably, the storage mechanism includes a material cylinder, the top of the material cylinder is connected to the bottom of the handle, an isolation bottom plate is arranged inside the material cylinder, a cavity is arranged below the isolation bottom plate, the cavity below the isolation bottom plate is filled with fertilizer, an isolation top plate is arranged above the isolation bottom plate, a piston plate is arranged above the isolation top plate, the piston plate is in sliding contact with the inner wall of the material cylinder, the bottom of the piston plate is sleeved on one end of the top of the piston rod, the outer wall of the piston rod is welded to the isolation bottom plate, the outer wall of the isolation top plate is welded to the inner wall of the material cylinder, the cavity between the isolation top plate and the isolation bottom plate is filled with oil, and a connecting platform is sleeved on the bottom of the piston rod;

[0013] By arranging an isolation bottom plate and an isolation top plate inside the material cylinder and filling oil between the two, the precise control of the fertilizer spreading process is realized. When the device is inserted into the soil, the oil between the isolation top plate and the isolation bottom plate cannot flow quickly under the restriction of the flow holes, thus providing sufficient supporting force for the discharging arm to enable it to smoothly insert into the soil. As the handle is continuously pressed down, the oil slowly and uniformly discharges upward through the flow holes, driving the isolation top plate and the material cylinder to continue moving downward, so that the fertilizer can flow into the adjusting mechanism through the communication groove and be finally discharged. This design utilizes the "damping" effect of the oil to realize the delayed discharging of the fertilizer, ensuring that the fertilizer is spread after being inserted into the soil, avoiding the fertilizer from accumulating on the soil surface and being washed away by rainwater. At the same time, this mechanism simplifies the operation process, eliminates the need to additionally set a fertilizer discharging switch, and improves the fertilization efficiency.

[0014] Preferably, a first spring is arranged between the isolation top plate and the isolation bottom plate, the first spring is sleeved outside the piston rod, an air return hole is opened inside the isolation top plate, a sealing block is arranged below the air return hole, the sealing block is sleeved outside the limiting rod and is in sliding contact with the limiting rod, a second spring is sleeved outside the limiting rod, the bottom of the limiting rod is connected to the isolation bottom plate, and there is a gap between the top of the limiting rod and the piston plate. When the device is lifted upward, due to the elasticity of the first spring being much greater than that of the two second springs, the first spring pushes the isolation top plate upward, so that the oil in the cavity between the isolation top plate and the piston plate can push open the sealing block, enabling the oil to quickly return to the cavity below the isolation top plate through the air return hole.

[0015] Preferably, a flow hole is provided inside the isolation top plate. There are two flow holes. A sealing rod is arranged inside the two flow holes. One end of the sealing rod is hemispherical. The outer wall of the sealing rod is in close fit with the inner wall of the flow hole. A thread is provided on the outer wall surface of the middle part of the sealing rod, and the middle part of the sealing rod is threadedly connected to the outer wall of the barrel through the thread. A knob is provided at one end of the sealing rod. By rotating the knob, the knob can drive the sealing rod to rotate, and then the sealing rod can move inside the flow hole through one end to adjust the size of the flow channel of the flow hole.

[0016] Preferably, the metering mechanism includes an adjusting pipe. One end of the bottom of the adjusting pipe is in sliding contact with the inner wall surface of the communication groove. The communication groove is arranged at the bottom of the barrel. The communication groove and the barrel are of an integral structure. The communication groove is in an annular structure. The communication groove is communicated with the inside of the barrel. One end of the outer walls on both sides of the adjusting pipe is welded to one end of the threaded rod. The threaded rod is in sliding contact with the hole groove on the outer wall at one end of the bottom of the barrel. The outside of the threaded rod is threadedly connected to the fastening block. By loosening the fastening block outside the threaded rod, the threaded rod and the adjusting pipe can move up and down. As the adjusting pipe moves up and down, the size of the space inside the communication groove can be adjusted, so that the amount of fertilizer entering the communication groove from the inside of the barrel can be adjusted.

[0017] Preferably, the adjusting mechanism includes a material guiding block. The material guiding block is fixedly connected to the bottom of the connecting platform. A hole groove is provided inside the material guiding block, and the top end of a discharge rod is connected to the inside of the hole groove. The inside of the discharge rod is in a hollow structure. The discharge rods are distributed at equal intervals in a ring shape. One end of the outer wall of the discharge rod is welded to the bottom end of the threaded ring. Threads are provided on the outer wall of the threaded ring. The outer wall of the threaded ring is threadedly connected to the inner wall of the adjusting ring. One end of the outer wall of the bottom of the adjusting ring is rotatably connected to the connecting ring. The outside of the connecting ring is rotatably connected to the top end of the connecting arm. One end of the bottom of the connecting arm is rotatably connected to the outer wall of the discharge arm. One end of the top of the discharge arm is rotatably connected to the bottom of the discharge rod. Both the discharge arm and the discharge rod are in a hollow structure inside, and the inside of the discharge arm and the discharge rod are communicated;

[0018] This adjusting mechanism can flexibly adjust the fertilization radius and evenly spread the fertilizer. The material guiding block is fixedly connected to the connecting platform to ensure the stability of the structure. At the same time, due to the annular equal-spacing distribution and hollow structure of the discharge rods, the fertilizer can be evenly distributed into each discharge arm; the threaded connection between the adjusting ring and the threaded ring, and the rotational connection of the connecting arm and the discharge arm enable the user to change the annular distribution diameter of the discharge arm by rotating the adjusting ring, so as to flexibly adjust the fertilization radius to adapt to different sizes of plants and soil conditions; this design not only improves the uniformity and accuracy of fertilization, but also enhances the versatility and operation convenience of the device, while ensuring the stability and reliability of the device during the working process.

[0019] Preferably, the discharging mechanism includes a discharging port which is opened on one side of the bottom of the discharging arm. A solid block is arranged inside the discharging port. Both sides at one end of the top of the solid block are in sliding contact with the inside of the sliding groove. One end of the bottom of the sliding groove is rotatably connected to both sides of the bottom of the discharging arm. A resistance plate is welded to one end of the top of the sliding groove.

[0020] Through the cooperation of the discharging port, the solid block, the sliding groove and the resistance plate, the precise discharge of the fertilizer and the automatic cleaning function of the discharging port are realized. The discharging port is opened on one side of the bottom of the discharging arm. The solid block inside is slidably connected to the discharging arm through the sliding groove and can be automatically opened and closed under the action of the resistance plate. When the discharging arm is inserted into the soil, the resistance plate contacts the soil and turns upward, driving the solid block to move, thereby opening the discharging port and enabling the fertilizer to be discharged smoothly. As the device is lifted upward, the solid block resets by its own weight and at the same time pushes out the residual fertilizer and soil at the bottom of the discharging arm, preventing the discharging port from being blocked, ensuring the continuity and high efficiency of the device, and at the same time improving the precision and reliability of fertilization.

[0021] Preferably, one side of the bottom of the discharging arm is in an inclined shape, and the bottom of the discharging arm is in sliding contact with the outer wall of the solid block through a hole groove. The solid block is made of metal.

[0022] By setting one side of the bottom of the discharging arm to be inclined and making it in sliding contact with the outer wall of the solid block through a hole groove, the function and performance of the discharging mechanism are further optimized. The inclined design of the discharging arm helps to reduce the resistance when inserting into the soil, making it easier to enter the deep soil. At the same time, it can better guide the fertilizer to be discharged when the device is lifted. The solid block is made of metal, which not only ensures the firmness and durability of its structure, but also can utilize the weight characteristics of the metal to ensure that the solid block can quickly reset by its own gravity when the device is lifted, thereby effectively pushing out the residual fertilizer and soil at the bottom of the discharging arm, further preventing the discharging port from being blocked, and improving the reliability and service life of the device.

[0023] The present invention provides a fertilizer spreading device for landscaping project construction, which has the following beneficial effects:

[0024] This fertilizer spreading device for landscaping project construction evenly distributes the fertilizer to each discharging rod through the material guiding block and further transports it to be discharged at the bottom of the discharging arm. The discharging arms are distributed at equal intervals in a ring shape to ensure that the fertilizer can be evenly spread around the green plant seedlings. By rotating the adjusting ring, its threaded cooperation with the threaded ring is used to move up and down, and the discharging arm is driven to rotate by means of the connecting arm, thereby adjusting the ring distribution diameter of the discharging arm and realizing the flexible adjustment of the fertilization radius. This design effectively avoids the problem of plant root burning caused by the too-close spreading of fertilizer particles, and at the same time ensures the uniformity of the annular quantitative discharging, significantly improving the precision and adaptability of fertilization.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0041] Embodiment 1:

[0042] Please refer to Figures 1-14 , the embodiments of the present invention provide a technical solution: a fertilizer spreading device for landscaping engineering construction, including: a handle 1; a material storage mechanism 2, which is installed at the bottom of the handle 1, and the material storage mechanism 2 is used for storing granular fertilizer; a metering mechanism 3, located at the bottom of the material storage mechanism 2, and the metering mechanism 3 is used for controlling the discharge of granular fertilizer; an adjusting mechanism 4, which is installed at the bottom of the metering mechanism 3, and the adjusting mechanism 4 is used for adjusting the size of the fertilization radius; a discharging mechanism 5, which is communicated with the metering mechanism 3, and the discharging mechanism 5 is used to cooperate with the metering mechanism 3 to achieve the fertilizer discharging work;

[0043] Through the coordinated action of the handle 1, the material storage mechanism 2, the metering mechanism 3, the adjusting mechanism 4 and the discharging mechanism 5, the device achieves the effects of precise fertilization and uniform fertilization. The material storage mechanism 2 stores granular fertilizer, and the metering mechanism 3 ensures the same amount of fertilizer discharged each time by controlling the discharge amount of the fertilizer, avoiding over-fertilization. The adjusting mechanism 4 flexibly adjusts the fertilization radius according to the size of the plant and soil conditions, so that the fertilizer can be evenly distributed around the root system of the plant, solving the problem of uneven fertilization of the existing device; the discharging mechanism 5 cooperates with the metering mechanism 3 to accurately discharge the fertilizer, avoiding the fertilizer from accumulating on the soil surface and being washed away by rainwater. This design utilizes the linkage principle of the mechanical structure. Through the coordinated work of each mechanism, it improves the accuracy and uniformity of fertilization, simplifies the operation process, and enhances the adaptability and practicability of the device.

[0044] Example 2:

[0045] Please refer to Figures 1-14 , this embodiment of the present invention provides a technical solution: a fertilizer spreading device for landscaping engineering construction. The storage mechanism 2 includes a material cylinder 201. The top of the material cylinder 201 is connected to the bottom of the handle 1. Inside the material cylinder 201, there is an isolation bottom plate 202. Below the isolation bottom plate 202, there is a cavity. The cavity below the isolation bottom plate 202 is filled with fertilizer. Above the isolation bottom plate 202, there is an isolation top plate 203. Above the isolation top plate 203, there is a piston plate 204. The piston plate 204 is in sliding contact with the inner wall of the material cylinder 201. The bottom of the piston plate 204 is sleeved on one end of the top of the piston rod 205. The outer wall of the piston rod 205 is welded to the isolation bottom plate 202. The outer wall of the isolation top plate 203 is welded to the inner wall of the material cylinder 201. The cavity between the isolation top plate 203 and the isolation bottom plate 202 is filled with oil. The bottom of the piston rod 205 is sleeved with a connecting platform 214; between the isolation top plate 203 and the isolation bottom plate 202, there is a first spring 206. The first spring 206 is sleeved outside the piston rod 205. Inside the isolation top plate 203, there is a return air hole 210. Below the return air hole 210, there is a sealing block 208. The sealing block 208 is sleeved outside the limit rod 209. The outside of the limit rod 209 is sleeved with a second spring 207. The bottom of the limit rod 209 is connected to the isolation bottom plate 202. There is a gap between the top of the limit rod 209 and the piston plate 204; inside the isolation top plate 203, there are two flow holes 211. Inside the two flow holes 211, there is a sealing rod 212. One end of the sealing rod 212 is hemispherical. The outer wall of the sealing rod 212 is in close fit with the inner wall of the flow hole 211. The middle outer wall surface of the sealing rod 212 is provided with threads, and the middle of the sealing rod 212 is threadedly connected to the outer wall of the material cylinder 201 through the threads. One end of the sealing rod 212 is provided with a knob 213; the metering mechanism 3 includes an adjusting pipe 301. One end of the bottom of the adjusting pipe 301 is in sliding contact with the inner wall surface of the communication groove 304. The communication groove 304 is arranged at the bottom of the material cylinder 201. The communication groove 304 and the material cylinder 201 are of an integral structure. The communication groove 304 is in an annular structure. The communication groove 304 is communicated with the inside of the material cylinder 201. The outer walls on both sides of the adjusting pipe 301 are welded to one end of the threaded rod 303. The threaded rod 303 is in sliding contact with the hole groove on the outer wall at one end of the bottom of the material cylinder 201. The outside of the threaded rod 303 is threadedly connected to the fastening block 302;

[0046] When the device is in use, hold the handle 1 and insert the bottom of the device into the soil. When the bottom of the device suddenly receives an impact force, due to the restriction of the oil filled between the upper isolation plate and the lower isolation plate by the flow hole 211, the oil cannot quickly flow into the cavity above the isolation top plate 203. As a result, there is sufficient supporting force at the bottom of the device to insert into the soil. When one end of the bottom of the device is inserted into the soil, as the handle 1 is continuously pressed down, the oil filled between the upper isolation plate and the lower isolation plate can slowly and evenly flow through the flow hole 211 into the cavity inside the isolation top plate 203. Since the oil at the bottom of the isolation top plate 203 is discharged upward, the isolation top plate 203 can continue to move downward with the barrel 201. When the barrel 201 continues to move downward, it will drive the connecting groove 304 to move downward. The granular fertilizer inside the connecting groove 304 can communicate with the annular groove on the outer side of the bottom of the connecting table 214, so that the waste can flow into the adjusting mechanism 4, and then flow through the adjusting mechanism 4 into the discharging mechanism 5. Through the "damping" effect generated by the oil between the isolation top plate 203 and the isolation bottom plate 202, the fertilizer can be discharged at a delayed time, so that the fertilizer can be discharged after being inserted into the soil, avoiding a large amount of fertilizer on the soil surface and being washed away by rain. Moreover, the device is easy to operate, without the need to set an additional fertilizer discharging switch, which simplifies the operation.

[0047] Embodiment 3:

[0048] Please refer to Figures 1-14 , the embodiment of the present invention provides a technical solution: a fertilizer spreading device for landscaping project construction. The adjusting mechanism 4 includes a material guiding block 401, which is fixedly connected to the bottom of the connecting table 214. There is a hole groove inside the material guiding block 401, and the top end of a discharging rod 402 is connected to the inside of the hole groove. The discharging rod 402 is of a hollow structure inside, and the discharging rods 402 are distributed in an annular and equally spaced manner. The outer wall of the discharging rod 402 is welded to the bottom end of a threaded ring 403. The outer wall of the threaded ring 403 is provided with threads, and the outer wall of the threaded ring 403 is threadedly connected to the inner wall of an adjusting ring 404. The bottom end outer wall of the adjusting ring 404 is rotatably connected to a connecting ring 405. The outside of the connecting ring 405 is rotatably connected to the top end of a connecting arm 406. The bottom end of the connecting arm 406 is rotatably connected to the outer wall of a discharging arm 407. The top end of the discharging arm 407 is rotatably connected to the bottom of the discharging rod 402. Both the discharging arm 407 and the discharging rod 402 are of a hollow structure inside, and the inside of the discharging arm 407 is communicated with the inside of the discharging rod 402;

[0049] After the fertilizer is dispersed into each discharge rod 402 through the channel inside the material guiding block 401, it is then discharged into the bottom of the discharge arm 407 through the discharge rod 402, and discharged from one end of the bottom of the discharge arm 407. Through the annularly and equally spaced discharge arms 407, the fertilizer can be evenly spread around the green plant seedlings. By rotating the adjusting ring 404, the adjusting ring 404 can move up and down on the outer wall of the threaded ring 403 through the internal thread of the inner wall. While the adjusting ring 404 is moving up and down, it can drive the discharge arm 407 to rotate through the connecting arm 406, thereby adjusting the diameter of the annular distribution of the discharge arm 407, achieving the effect of adjusting the fertilization radius, which is beneficial to avoiding the root burn of the plant caused by the fertilizer particles being too close to the root of the plant during the spreading process, and at the same time is beneficial to the annular quantitative discharge to ensure the uniformity of the fertilizer spreading.

[0050] Example 4:

[0051] Please refer to Figures 1-14 , the embodiment of the present invention provides a technical solution: a fertilizer spreading device for a landscaping project construction, the discharging mechanism 5 includes a discharging port 501, the discharging port 501 is opened on one side of the bottom of the discharging arm 407, a solid block 503 is arranged inside the discharging port 501, both sides of one end of the top of the solid block 503 are in sliding contact with the inside of the sliding groove 502, one end of the bottom of the sliding groove 502 is rotatably connected to both sides of the bottom of the discharging arm 407, and a resistance plate 504 is welded to one end of the top of the sliding groove 502; one side of the bottom of the discharging arm 407 is in an inclined shape, and the bottom of the discharging arm 407 is in sliding contact with the outer wall of the solid block 503 through a hole groove, and the solid block 503 is made of metal material;

[0052] When the discharging arm 407 is inserted into the soil, the resistance plate 504 will contact the soil, so that the resistance plate 504 can be turned upwards. During the process of the resistance plate 504 turning upwards, it can drive one end of the sliding groove 502 to rotate upwards, so that the sliding groove 502 can drive the solid block 503 to move obliquely, so that the discharging port 501 can be opened, so that the fertilizer at the bottom end inside the discharging arm 407 can be discharged through the discharging port 501 as the device is lifted upwards, so that the fertilizer at the bottom end of the discharging arm 407 can remain in the soil. At the same time, as the device is lifted upwards, the solid block 503 will gradually return downwards under its own weight, thereby pushing out a small amount of the soil and residual fertilizer that enter the inside of one end of the bottom of the discharging arm 407, which is beneficial to keeping the discharging port 501 unblocked and avoiding the blockage caused by the entering soil and residual fertilizer affecting the next discharging.

[0053] Working principle: First, the operator holds the handle 1 and inserts the bottom of the device into the soil. At this time, due to the oil filled between the isolation top plate 203 and the isolation bottom plate 202 in the material storage mechanism 2 being restricted by the flow holes 211 and unable to flow quickly, sufficient support force is provided for the discharge arm 407, enabling it to smoothly insert into the soil. As the handle 1 is continuously pressed down, the oil between the isolation top plate 203 and the isolation bottom plate 202 slowly and uniformly discharges upward under the restriction of the flow holes 211, pushing the isolation top plate 203 to continue moving downward with the material cylinder 201, driving the communication groove 304 to communicate with the annular groove on the outer side of the bottom of the connection table 214, and enabling the granular fertilizer to flow into the adjustment mechanism 4. The fertilizer is dispersed to each discharge rod 402 through the channel inside the guide block 401, then discharged into the bottom of the discharge arm 407 through the discharge rod 402, and finally discharged from one end of the bottom of the discharge arm 407. The discharge arms 407 are distributed at equal intervals in a ring shape to ensure that the fertilizer can be evenly spread around the green plant seedlings. By rotating the adjustment ring 404, its threaded cooperation with the threaded ring 403 is used to move up and down, and the discharge arm 407 is driven to rotate by means of the connecting arm 406, thereby adjusting the ring distribution diameter of the discharge arm 407 and achieving flexible adjustment of the fertilization radius. This process utilizes the "damping" effect generated by the oil between the isolation top plate 203 and the isolation bottom plate 202 to achieve delayed discharge of the fertilizer, ensuring that the fertilizer is spread after being inserted into the soil, avoiding the fertilizer from accumulating on the soil surface and being washed away by rainwater. At the same time, there is no need to additionally set a fertilizer discharge switch, simplifying the operation process and improving the fertilization efficiency and accuracy.
