A tracked garden multi-terrain precision fertilization device

Abstract

This invention relates to the technical field of fertilization devices, and more particularly to a tracked, multi-terrain precision fertilization device for gardens. It includes: a mobile vehicle body; a first housing connected to the top of the mobile vehicle body; a second housing connected to the top of the first housing; a controller mounted on the side of the second housing; and a connecting frame connected to the side of the second housing. This invention uses a first electric push rod to drive a hollow tube and a sliding sleeve into the soil. The sliding sleeve has a first channel and a second channel inside. During fertilization, the lower end of the hollow tube blocks the bottom of the sliding sleeve, preventing soil from entering and causing blockage. Subsequently, the expansion of an air bladder securely fixes the sliding sleeve in the soil. When the first electric push rod drives the hollow tube upwards, the lower end of the hollow tube detaches from the bottom of the sliding sleeve, allowing fertilizer to smoothly enter the soil through the first channel, solving the problem of outlet blockage caused by soil residue in traditional fertilization devices.

Description

Technical Field

[0001] This invention relates to the technical field of fertilization devices, and more particularly to a tracked, multi-terrain precision fertilization device for gardens. Background Technology

[0002] With urbanization and increasing demand for green environments, the importance of landscaping projects has become increasingly prominent. Fertilization is an essential part of ensuring the healthy growth of plants. Traditional fertilization methods rely heavily on manual operation, which is not only inefficient but also makes it difficult to ensure the uniform distribution of fertilizer. Especially for large-scale or complex-topographical garden areas, traditional methods obviously cannot meet the needs of modern garden management. Therefore, various fertilization devices have emerged to improve fertilization efficiency and accuracy.

[0003] Currently, most commercially available fertilization equipment requires operators to manually insert the end of the applicator into the soil around the plant roots and then press a switch to spray liquid fertilizer directly into the soil. While this method improves accuracy and efficiency to some extent, it also presents new challenges. Specifically, when the applicator enters the soil, its complex structure and presence of particles of varying sizes make it easy for soil to enter the outlet, especially in humid environments. Once soil enters and remains in the outlet, it mixes with the remaining liquid fertilizer over time. As the fertilizer evaporates, these residues solidify, affecting the applicator's performance and potentially clogging the outlet, hindering future use. Furthermore, long-term residue can breed bacteria or trigger other chemical changes, further damaging the applicator's function and lifespan. Summary of the Invention

[0004] In view of this, the present invention provides a tracked garden multi-terrain precision fertilization device, which can overcome the shortcomings of existing fertilization devices, where soil is easily left at the discharge port and causes blockage.

[0006] As a preferred embodiment of the present invention, the conveying assembly includes: a pump, installed on the side of the second housing; a pumping pipe, with both ends connected to the inlet of the first housing and the pump and kept in communication; a feeding pipe, connected to the outlet of the pump and kept in communication; and a first hollow ring, connected to the top of the sliding sleeve, with the upper end of the first channel communicating with the inside of the first hollow ring, and the end of the feeding pipe connected to the first hollow ring and kept in communication.

[0007] As a preferred embodiment of the present invention, the fixing component includes: an airbag symmetrically connected to the sliding sleeve, with the lower end of the second channel communicating with the interior of the airbag; and a control mechanism disposed on the second housing for controlling the airbag to inflate or contract.

[0008] As a preferred embodiment of the present invention, the control mechanism includes: an air pump installed on the side of the second housing; a second hollow ring connected to the top of the first hollow ring; a vertical pipe symmetrically connected to the bottom of the second hollow ring and kept in communication, with the lower end of the vertical pipe connected to the upper end of the second channel; a connecting pipe connected to the second hollow ring and kept in communication; and a solenoid valve installed at the end of the connecting pipe, with both the air outlet and air inlet of the air pump connected to the solenoid valve.

[0009] As a preferred embodiment of the present invention, it further includes: an inclined tube connected to and connected to the hollow insert tube, with symmetrical through holes at the lower end of the hollow insert tube; a square plate connected to the end of the inclined tube; a feeding pipe connected to and connected to the bottom of the second box; a hollow frame connected to and connected to the bottom of the feeding pipe, with a discharge port on the side of the hollow frame; a baffle assembly disposed on the hollow frame to block the side of the discharge port; a protective assembly disposed on the second box to protect the fertilizer inside the second box; and a collecting assembly disposed inside the second box to concentrate the fertilizer inside the second box at the feeding pipe.

[0010] As a preferred embodiment of the present invention, the material blocking assembly includes: a slide rod, symmetrically slidably connected to the hollow frame; a baffle plate, connected to the lower end of the slide rod, and the baffle plate is located directly below the square plate; and a return spring, wrapped around the outside of the slide rod, with both ends of the return spring connected to the slide rod and the hollow frame respectively.

[0011] As a preferred embodiment of the present invention, the protective component includes: a fixed cover plate connected to the top of the second housing; and a sliding cover plate slidably connected to the inner side of the fixed cover plate, with the bottom of the sliding cover plate contacting the top of the second housing.

[0012] As a preferred embodiment of the present invention, the material collection assembly includes: a first drive motor, mounted on the side of the second housing; a bidirectional spiral rod, rotatably connected to the second housing, with the end of the bidirectional spiral rod connected to the output shaft of the first drive motor; and a baffle, connected to the inner wall of the second housing, with the bidirectional spiral rod rotatably penetrating through the baffle, the baffle being located directly above the discharge pipe.

[0014] As a preferred embodiment of the present invention, it further includes: a camera, which is installed on the side of the second housing.

[0015] Beneficial effects: 1. This invention uses a first electric push rod to drive a hollow tube and a sliding sleeve to be inserted into the soil. The sliding sleeve has a first channel and a second channel inside. During fertilization, the lower end of the hollow tube blocks the bottom of the sliding sleeve, preventing soil from entering the sliding sleeve and causing blockage. Subsequently, the expansion of the air bladder can firmly fix the sliding sleeve in the soil. When the first electric push rod drives the hollow tube to move upward, the lower end of the hollow tube can be separated from the bottom of the sliding sleeve, allowing fertilizer to smoothly enter the soil through the first channel, solving the problem of outlet blockage caused by soil residue in traditional fertilization devices.

[0016] 2. This invention not only supports the application of liquid fertilizers, but also has a specially designed mechanism for the application of solid fertilizers. An inclined tube is connected to the upper right side of the hollow tube and communicates with it through a through hole. A square plate is located at the top of the inclined tube. The material collection component ensures that the solid fertilizer is quantitatively fed into the hollow frame. Then, the opening and closing of the discharge port is controlled by the material blocking component, so that the solid fertilizer can be accurately delivered to the predetermined position, thereby achieving efficient management of liquid and solid fertilizers and enhancing the applicability and flexibility of the device.

Detailed Implementation

[0028] 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.

[0029] Example: A tracked, multi-terrain precision fertilization device for gardens, such as... Figures 1-6 As shown, the system includes a mobile vehicle body 1, a first housing 2, a second housing 3, a controller 4, a connecting frame 5, a first electric push rod 6, a hollow tube 7, a sliding sleeve 8, a connecting block 9, a telescopic rod 10, a connecting spring 11, a camera 40, a conveying assembly, and a fixing assembly. The top of the mobile vehicle body 1 is connected to the first housing 2, and the top of the first housing 2 is connected to the second housing 3. The bottom of the second housing 3 is sloped. The controller 4 is installed on the rear left side of the second housing 3. The connecting frame 5 is connected to the middle left side of the second housing 3. The camera 40 is installed on the front left side of the second housing 3. The first electric push rod 6 is installed on the left side of the connecting frame 5. The telescopic rod of the first electric push rod 6 is connected to the hollow tube 7. The outer side of the hollow tube 7... A sliding sleeve 8 is slidably connected, and the lower end of the hollow tube 7 blocks the bottom of the sliding sleeve 8. Four first channels 801 are symmetrically opened inside the sliding sleeve 8, and the lower ends of the four first channels 801 are all connected to the inner wall of the sliding sleeve 8. Two second channels 802 are also symmetrically opened inside the sliding sleeve 8. Connecting blocks 9 are connected to the upper parts of the hollow tube 7 and the sliding sleeve 8. A telescopic rod 10 is connected between the left parts of the two connecting blocks 9, and a connecting spring 11 is wound around the outside of the telescopic rod 10. The two ends of the connecting spring 11 are respectively connected to the two connecting blocks 9. The second box 3 is provided with a conveying component for conveying liquid fertilizer into the first channel 801. The second box 3 is also provided with a fixing component for fixing the sliding sleeve 8 in the soil.

[0030] like Figure 5 As shown, the conveying assembly includes a pump 12, a pumping pipe 13, a feeding pipe 14, and a first hollow ring 15. The pump 12 is installed on the front left side of the second housing 3. The pumping pipe 13 is connected to the front left side of the first housing 2 and keeps them in communication. The feeding pipe 14 is connected to the outlet of the pump 12 and keeps them in communication. The feeding pipe 14 is spirally coiled. The top of the sliding sleeve 8 is connected to the first hollow ring 15, and the upper ends of the four first channels 801 are all connected to the inside of the first hollow ring 15. The end of the feeding pipe 14 away from the pump 12 is connected to the front side of the first hollow ring 15 and keeps them in communication.

[0031] like Figure 5 and Figure 6As shown, the fixing assembly includes an airbag 16 and a control mechanism. The airbag 16 is symmetrically connected to the sliding sleeve 8, and the lower ends of the two second channels 802 are respectively connected to the top of the two airbags 16 and kept in communication. The second housing 3 is provided with a control mechanism for controlling the expansion or contraction of the airbag 16. The control mechanism includes an air pump 17, a second hollow ring 18, a vertical pipe 19, a connecting pipe 20, and a solenoid valve 21. The air pump 17 is installed on the rear left side of the second housing 3. The top of the first hollow ring 15 is connected to the second hollow ring 18. The bottom of the second hollow ring 18 is symmetrically connected to the vertical pipe 19 and kept in communication. The lower ends of the two vertical pipes 19 are respectively connected to the upper ends of the two second channels 802 and kept in communication. The rear side of the second hollow ring 18 is connected to the connecting pipe 20 and kept in communication. The connecting pipe 20 is spirally coiled, and the rear end of the connecting pipe 20 is equipped with a solenoid valve 21. The solenoid valve 21 is a four-way valve, and the air outlet and air inlet of the air pump 17 are both connected to the solenoid valve 21.

[0032] First, place the device in the garden. Then, add an appropriate amount of liquid fertilizer into the first container 2. Next, control the moving vehicle 1 to move to the designated position, which in turn moves the hollow insertion tube 7 to the designated position. Then, the controller 4 controls the first electric push rod 6 to drive the hollow insertion tube 7 and the sliding sleeve 8 downwards. The sliding sleeve 8 drives the first hollow ring 15 and the second hollow ring 18 downwards, and the spiral parts of the feeding pipe 14 and the connecting pipe 20 will extend accordingly. Subsequently, both the hollow insertion tube 7 and the sliding sleeve 8 are inserted into the soil. Because the lower end of the hollow insertion tube 7 blocks the soil, the soil will not enter the sliding sleeve 8 and cause blockage. Controller 4 controls solenoid valve 21 to connect the air inlet of air pump 17 to the outside and the air outlet of air pump 17 to connecting pipe 20. Simultaneously, controller 4 controls air pump 17 to inject outside air into connecting pipe 20. The air in connecting pipe 20 enters airbag 16 through second hollow ring 18, vertical pipe 19, and second channel 802, causing airbag 16 to inflate. Through the friction between airbag 16 and soil, sliding sleeve 8 is fixed in the soil. Then, controller 4 controls first electric push rod 6 to drive hollow insertion tube 7 upward. Because sliding sleeve 8 is fixed in the soil, it will not... As the hollow tube 7 moves upward, its lower end will no longer block the bottom of the sliding sleeve 8, and the two connecting blocks 9 will move away from each other. The telescopic rod 10 will extend, and the connecting spring 11 will be stretched. Simultaneously, the controller 4 controls the pump 12 to draw liquid fertilizer from the second box 3 through the pumping pipe 13, and delivers the liquid fertilizer to the first channel 801 through the feeding pipe 14 and the first hollow ring 15. This allows the liquid fertilizer to enter the sliding sleeve 8 along the first channel 801 and fall into the soil through the bottom of the sliding sleeve 8, completing the fertilization operation. Afterward, the controller 4 will control the pump 12 to stop working and control the electromagnetic... Valve 21 connects the air inlet of air pump 17 to the connecting pipe 20 and connects the air outlet of air pump 17 to the outside. At the same time, controller 4 controls air pump 17 to draw air from air bag 16, causing air bag 16 to contract and return to its original state. At this time, connecting spring 11 will return to its original state, driving sliding sleeve 8 to move upward and separate from the soil, so that hollow tube 7 can re-block the bottom of sliding sleeve 8. Repeat the above operation to fertilize other parts of the soil. Camera 40 can be equipped with a remote control panel. The image captured by camera 40 is uploaded to the control panel for display, allowing users to remotely control the device to perform fertilization operations.

[0033] Since most fertilizer application devices on the market are either single-function liquid fertilizer or solid fertilizer application devices, they cannot simultaneously apply both types of fertilizer. Therefore, this device is designed to include both liquid fertilizer and solid fertilizer application modes. The above describes the working principle of the liquid fertilizer application mode. Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the device also includes an inclined tube 23, a square plate 24, a feeding pipe 25, a hollow frame 26, a baffle assembly, a protective assembly, and a collecting assembly. The upper right side of the hollow insert 7 is connected to the inclined tube 23 and remains connected. The lower part of the hollow insert 7 has symmetrical through holes 22 located inside the sliding sleeve 8. The upper end of the inclined tube 23 is connected to the square plate 24. The bottom of the second housing 3 is connected to the feeding pipe 25 and remains connected. The bottom of the feeding pipe 25 is connected to the hollow frame 26 and remains connected. The left side of the hollow frame 26... The lower part has a discharge port 2601. The hollow frame 26 is equipped with a baffle assembly to block the left side of the discharge port 2601. The second box 3 is equipped with a protective assembly to protect the fertilizer inside the second box 3. The second box 3 is equipped with a collecting assembly to concentrate the fertilizer inside the second box 3 at the discharge pipe 25. The baffle assembly includes a slide rod 27, a baffle 28 and a return spring 29. The slide rod 27 is symmetrically slidably connected to the lower left side of the hollow frame 26. The lower ends of the two slide rods 27 are connected. A baffle 28 blocks the left side of the discharge port 2601 and is located directly below the square plate 24. Return springs 29 are wound around the outer sides of both sliding rods 27, with the two ends of the return springs 29 connected to the upper end of the sliding rods 27 and the lower left side of the hollow frame 26, respectively. The protective assembly includes a fixed cover plate 30 and a sliding cover plate 31. The fixed cover plate 30 is connected to the top left side of the second housing 3, and the sliding cover plate 31 is slidably connected to the right side of the fixed cover plate 30. The bottom of the sliding cover plate 31 is flush with the top of the second housing 3. Contact; The material collection assembly includes a first drive motor 32, a bidirectional screw rod 33, and a baffle 34. The first drive motor 32 is installed on the front left side of the second housing 3. The bidirectional screw rod 33 is rotatably connected to the left side of the second housing 3, and the front end of the bidirectional screw rod 33 is connected to the output shaft of the first drive motor 32. The baffle 34 is connected to the middle of the bottom inside the second housing 3, and the bidirectional screw rod 33 rotates through the left side of the baffle 34. The baffle 34 is located directly above the feed pipe 25, and both the front and rear sides of the baffle 34 are inclined surfaces.

[0034] When solid fertilizer needs to be applied to the plants, the device needs to be switched to solid fertilizer application mode via controller 4, so that the conveying component does not work. Similarly, when the device is switched to liquid fertilizer application mode, the collecting component does not work, thus ensuring that the operation of the liquid fertilizer system and the solid fertilizer system does not interfere with each other. First, the sliding cover 31 can be slid open to the left, and then an appropriate amount of solid fertilizer can be placed into the second box 3. The baffle 34 can block the top of the discharge pipe 25 to prevent solid fertilizer from accumulating and clogging above the discharge pipe 25. The bottom of the second housing 3 and the front and rear sides of the baffle 34 are both sloped, so the solid fertilizer will be concentrated at the bidirectional spiral rod 33. Then the sliding cover 31 is slid to the right to close. When the device moves to the designated position, the controller 4 controls the first drive motor 32 to drive the bidirectional spiral rod 33 to rotate. The bidirectional spiral rod 33 can transport a certain amount of solid fertilizer to the top of the feed pipe 25, so that the solid fertilizer falls down into the hollow frame 26 through the feed pipe 25. When the hollow insert 7 moves downward, the hollow insert 7 will drive the inclined tube 23. As the square plate 24 moves downwards, when it contacts the baffle 28, the square plate 24 will press the baffle 28 downwards, so that the baffle 28 no longer blocks the left side of the discharge port 2601. At the same time, the baffle 28 will drive the sliding rod 27 downwards, compressing the return spring 29. Subsequently, the upper end of the inclined tube 23 will align with the left side of the discharge port 2601, so that the solid fertilizer in the hollow frame 26 will fall into the inclined tube 23 and enter the hollow insertion tube 7 through the inclined tube 23. The solid fertilizer in the hollow insertion tube 7 will fall through the through hole 22. The material is fed into the sliding sleeve 8 and falls down into the soil through the bottom of the sliding sleeve 8 to complete the fertilization operation. When the hollow tube 7 moves upward to reset, the hollow tube 7 will drive the inclined tube 23 and the square plate 24 to move upward to reset, so that the square plate 24 is separated from the baffle 28. The reset spring 29 will return to its original state, driving the baffle 28 and the sliding rod 27 to move upward, so that the baffle 28 blocks the left side of the discharge port 2601 again. Since the through hole 22 is always located inside the sliding sleeve 8, the situation of the through hole 22 being blocked by soil can be avoided.

[0035] like Figure 10As shown, it also includes a mounting bracket 35, a second electric push rod 36, a second drive motor 37, a circular plate 38, and levers 39. The mounting bracket 35 is connected to the middle right side of the first housing 2. The second electric push rod 36 is mounted on the right side of the mounting bracket 35. The second drive motor 37 is mounted on the telescopic rod of the second electric push rod 36. The circular plate 38 is connected to the output shaft of the second drive motor 37. Multiple levers 39 are evenly spaced at the bottom of the circular plate 38. After each fertilization, the device can be controlled to move a specified distance to the left, causing the circular plate 38 to... 8. Move to directly above the fertilization site, then controller 4 controls the second electric push rod 36 to drive the second drive motor 37, the circular plate 38 and the lever 39 to move downwards, and controls the second drive motor 37 to drive the circular plate 38 and the lever 39 to rotate. When the lever 39 contacts the soil surface of the fertilization site, the lever 39 can level the soil surface of the fertilization site. Then controller 4 controls the second electric push rod 36 to drive the second drive motor 37, the circular plate 38 and the lever 39 to move upwards to reset, and controls the second drive motor 37 to stop working.

[0036] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
