Description

Technical Field

[0001] This invention relates to the field of vegetable fertilization devices, and more specifically, to a quantitative fertilization device for vegetable cultivation. Background Technology

[0002] Vegetable fertilization devices are mainly used in greenhouses, open-field vegetables, and hydroponics to achieve precise, efficient, and environmentally friendly fertilization.

[0003] Chinese Patent Publication No. CN114568090A discloses a high-efficiency and convenient fertilization device for vegetable seedling planting. It includes a fertilization cover for applying fertilizer by digging up the soil, a fertilization pipe for unloading fertilizer connected directly above the fertilization cover, and a fertilizer cylinder connected directly above the fertilization pipe. The inside of the fertilization cover is provided with a seedling protection cover for spreading fertilizer in a circle. Both the fertilization cover and the seedling protection cover are shell-shaped with a round bottom and a narrow top. The bottom side of the fertilization cover has radially symmetrical grooves along its central axis. A fertilization handle is provided on one side of the top of the movable pipe.

[0004] The above-mentioned technical solution avoids direct contact between fertilizer and vegetable seedlings, ensuring that the seedlings grow healthily without fertilizer damage. It has promotion and practical value. However, some existing vegetable fertilization devices are not easy to implement in greenhouses due to space limitations. Moreover, although traditional small fertilization devices can complete the fertilization operation, they cannot apply fertilizer quantitatively around the vegetables according to the type of vegetables. This can lead to excessive or insufficient fertilizer around the vegetables, affecting their planting and development, and thus affecting the overall yield of the vegetables.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) This fertilization metering device for vegetable cultivation operates by rotating gears that drive multiple metering cylinders according to the required amount of fertilizer for the vegetables. When the corresponding metering cylinder reaches the position of the retaining ring, the knob stops rotating. When the plow reaches the vegetable to be fertilized, the guide rod moves, causing the top and bottom plates to move. The bottom plate blocks the bottom of the metering cylinder, while the top plate separates from the surface of the metering cylinder. At this point, the top opening of the metering cylinder opens, and fertilizer granules fall into the cylinder under their own weight. The guide rod then resets, and the top plate resets, blocking the surface of the metering cylinder. The chassis resets, opening the bottom of the metering cylinder. At this point, the fertilizer granules inside the metering cylinder fall into the rotating drum under their own weight, passing through the corrugated pipe and the discharge hole of the plow blade into the soil next to the vegetables to be fertilized. Compared to traditional partial fertilization devices, this device can adjust the corresponding metering cylinder according to the amount of fertilizer required by the vegetables, ensuring that the amount of fertilizer needed by the vegetables is appropriate. This avoids insufficient fertilizer affecting the growth and development of the vegetables, while also preventing excessive fertilizer from burning them, thus ensuring the planting and development of the vegetables and ultimately guaranteeing the overall yield.

[0019] 2) When using this quantitative fertilization device for vegetable cultivation, the installation process involves first inserting the rotating column on the surface of the rotating drum into the two inner grooves, then installing the mounting block in the inner grooves to limit the rotation column, and then attaching the upper connecting cylinder to the top of the rotating drum. During the attachment process, first attach the fixing column on the surface of the upper connecting cylinder into the groove, then rotate the upper connecting cylinder clockwise, and finally rotate the locking device to lock the surface of the fixing column. This allows for quick installation of the vegetable fertilization device and also facilitates its quick disassembly. This makes it suitable not only for operation in the limited space of a greenhouse but also for easy transfer and transportation of the vegetable fertilization device. Attached Figure Description

[0033] 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.

[0034] Example 1: Please refer to Figure 1 - Figure 12A fertilization metering device for vegetable cultivation includes a rotating drum 1 and an upper connecting drum 2, which are snapped together for easy assembly and disassembly. The inner wall of the upper connecting drum 2 has a rotating groove 3, and a matching rotating tooth 4 is rotatably connected inside the groove 3. Multiple through-type metering cylinders 5 are fixedly mounted on the surface of the rotating tooth 4. The metering cylinders 5 are used for metering fertilizer granules. The multiple metering cylinders 5 increase in size clockwise around the rotating tooth 4. A support 6 is fixedly mounted on the inner wall of each metering cylinder 5. A through-type guide rod 7 is slidably connected to the surface of the support 6. The guide rod 7 is longer than the metering cylinder 5. A base plate 8 is fixedly mounted at one end of the guide rod 7, and a top plate 8 is fixedly mounted at the other end. A cone seat 10 is fixedly installed on the surface of the top plate 9 and the base plate 8. The cone seat 10 is designed to facilitate the feeding of fertilizer granules and prevent fertilizer granules from being left behind and accumulating. A locking post 12 is fixedly installed on the surface of the top plate 9. A limit seat 13 is fixedly installed on the top surface of the locking post 12. A cap 14 is snapped onto the top surface of the upper connecting cylinder 2. The cap 14 is used to seal the top of the upper connecting cylinder 2. A movable rod 15 is slidably connected to the surface of the cap 14. A vertical frame 16 is fixedly installed at one end of the movable rod 15. A matching movable frame 17 is slidably connected inside the vertical frame 16. A retaining ring 18 matching the locking post 12 is fixedly installed on the bottom surface of the movable frame 17. A ramp ring 19 is fixedly installed on the surface of the rotating gear 4. The design of 19 facilitates the contact and separation of the retaining ring 18 and the retaining post 12. A top post 20, which contacts the inclined ring 19, is fixedly installed on the inner side of the movable frame 17. Based on the amount of fertilizer required by the vegetables, the gear 26 rotates, causing the rotating gear 4 to rotate, which in turn rotates multiple metering cylinders 5. When the metering cylinder 5 corresponds to the position of the retaining ring 18, the knob 27 stops rotating. When the plow blade 36 reaches the vegetable to be fertilized, the guide rod 7 moves, causing the top plate 9 and the bottom plate 8 to move. The bottom plate 8 blocks the bottom of the metering cylinder 5, and the top plate 9 separates from the surface of the metering cylinder 5. At this time, the top opening of the metering cylinder 5 opens, and the fertilizer granules fall into the metering cylinder 5 under their own weight. Then, the guide rod 7 is reset, the top plate 9 is reset to block the surface of the metering cylinder 5, and the bottom plate 8 is reset to open the bottom opening of the metering cylinder 5. At this time, the fertilizer granules inside the metering cylinder 5 fall into the rotating cylinder 1 under its own weight, and fall into the soil next to the vegetables to be fertilized through the discharge holes of the corrugated pipe 37 and the plow blade 36. Compared with traditional partial fertilization devices, this fertilization device can adjust the corresponding metering cylinder 5 to fill and fertilize according to the amount of fertilizer required by the vegetables, ensuring that the amount of fertilizer required by the vegetables is appropriate, avoiding insufficient fertilizer affecting the growth of the vegetables, and avoiding excessive fertilizer causing the vegetables to burn, thus ensuring the planting and development of the vegetables and thus ensuring the overall yield of the vegetables.

[0035] Each guide rod 7 has a spring 11 fitted onto its surface for resetting its movement. Spring 11 is used to reset the cone seat 10. One end of spring 11 is fixedly connected to the cone seat 10, and the other end of spring 11 is fixedly connected to the bracket 6. A spring 21 is elastically connected between the movable frame 17 and the vertical frame 16. One end of spring 21 is fixedly connected to the vertical frame 16, and the other end of spring 21 is fixedly connected to the movable frame 17. Spring 21 is used to reset the vertical frame 16.

[0036] A support base 22 is fixedly installed on the inner wall of the upper receiving cylinder 2. The support base 22 is designed in the shape of a rod to ensure the falling of fertilizer granules. A support column 23 is fixedly installed on the surface of the support base 22. The support column 23 is designed to support the rotating tooth 4. One end of the support column 23 is rotatably connected to the rotating tooth 4. A slot 24 communicating with the rotating groove 3 is opened on the surface of the upper receiving cylinder 2. Two fixing plates 25 are symmetrically fixedly installed on the surface of the upper receiving cylinder 2. The two fixing plates 25 are located on both sides of the slot 24.

[0037] A gear 26 that meshes with the rotating gear 4 is rotatably connected between two fixed plates 25. A knob 27 is rotatably connected to the surface of one of the fixed plates 25. One end of the knob 27 passes through the surface of the fixed plate 25 and is fixedly connected to the surface of the gear 26.

[0038] A movable disc 28 is fixedly mounted on the surface of the movable rod 15. A spring 29 is used to reset the movable disc 28. A spring 29 is elastically connected between the movable disc 28 and the cap 14. The spring 29 is sleeved on the surface of the movable rod 15. One end of the spring 29 is fixedly connected to the movable disc 28, and the other end of the spring 29 is fixedly connected to the cap 14. A movable head 30 is slidably connected to the surface of the cap 14. One end of the movable head 30 is fixedly connected to the movable rod 15.

[0039] Two uprights 31 are symmetrically arranged on both sides of the bottom end of the rotating drum 1. Side frames 32 are fixedly installed on the surface of each of the two uprights 31. Rotary wheels 33 are rotatably connected to the inner side of each of the two side frames 32. The addition of the rotary wheels 33 makes it convenient for personnel to push and saves time and effort. A motor 34 is fixedly installed on the surface of one of the side frames 32. The motor 34 is a conventional electric motor in the prior art. The output end of the motor 34 drives the two rotary wheels 33 to rotate.

[0040] An inner frame 35 is fixedly installed between the two upright frames 31. A through-type plow blade 36 is fixedly installed on the bottom surface of the inner frame 35. The plow blade 36 is a conventional plow blade 36 in the prior art. A discharge hole is opened at the rear of the plow blade 36. A corrugated pipe 37 is provided between the plow blade 36 and the rotating drum 1. The corrugated pipe 37 is a conventional flexible corrugated pipe 37 in the prior art. One end of the corrugated pipe 37 is connected to the rotating drum 1, and the other end of the corrugated pipe 37 is connected to the discharge hole of the plow blade 36.

[0041] The upper connecting cylinder 2 is fixedly installed with a feeding pipe 38 that communicates with it. The feeding pipe 38 is located above the rotating gear 4. The upper connecting cylinder 2 is fixedly installed with a handle 39, which is installed on the opposite side of the feeding pipe 38.

[0042] The steps for using this invention are as follows: First, install the vegetable fertilization device. Observe the vegetable to be fertilized to determine the required amount of fertilizer. Press the movable head 30 with your right hand. The movable head 30 moves, causing the movable rod 15 to move. The movable rod 15 moves the movable disc 28, stretching the spring 29. The movable rod 15 also moves the vertical frame 16 and the movable frame 17. The movable frame 17 moves the retaining ring 18 on the surface of the retaining post 12. The movable frame 17 moves the top post 20 on the surface of the inclined ring 19. The inclined ring 19 gradually presses against the top post 20. After being compressed, the top post 20 moves the movable frame 17 inwards towards the vertical frame 16, compressing the spring 21. The movable frame 17 then causes the retaining ring 18 to disengage. Remove the pin 12, then turn the knob 27 with your left hand. The rotation of knob 27 causes gear 26 to rotate (knob 27 has a scale on its surface to observe the angle of rotation, and markings on its surface to indicate the position of each metering cylinder 5). Gear 26 rotates, causing gear 4 to rotate, which in turn rotates multiple metering cylinders 5. When the corresponding metering cylinder 5 rotates to the position corresponding to the retaining ring 18, stop turning knob 27. At this point, release the pressure on the movable head 30 with your right hand. The movable rod 15 then resets under the action of spring 3 29, causing the top pin 20 to gradually reset. This, in turn, causes the retaining ring 18 to reset under the action of spring 2 21 and lock onto the surface of the pin 12 (the retaining ring 18 is located inside the lower part of the upper connecting cylinder 2). The rotating frame 44 is then rotated, causing the two auxiliary wheels 45 to rotate as well. When the two auxiliary wheels 45 come into contact with the ground, the rotation of the rotating frame 44 stops. At this point, fertilizer granules can be poured into the inside of the feeding pipe 38. The fertilizer granules inside the feeding pipe 38 flow into the upper receiving cylinder 2 and are blocked by the rotating teeth 4 (at this time, the top plate 9 closes the metering cylinder 5). The motor 34 is then turned on, and the handle 39 is pushed. The motor 34 rotates, causing the rotating wheel 33 to rotate. The rotating wheel 33 rotates, causing the entire vegetable fertilization device to move. At this time, the two upright frames 31 move, causing the inner frame 35 and the plow blade 36 to move. The plow blade 36 moves to plow the soil. When the plow blade 36 reaches the side of the vegetable to be fertilized, the right hand pulls the movable head 30. The movable head 30 moves, causing the movable rod 15 to move towards... The cap 14 slides in the direction of movement, the movable rod 15 moves, causing the movable disc 28 to move and compressing the spring 29. The movable rod 15 moves, causing the vertical frame 16 and the retaining ring 18 to move. The retaining ring 18 moves, causing the limiting seat 13 to move. The limiting seat 13 moves, causing the top plate 9 to move. The top plate 9 moves, causing the guide rod 7 and the base plate 8 to move upward. The base plate 8 moves upward, causing the cone seat 10 to move and compressing the spring 11. The movement of the base plate 8 blocks the bottom of the metering cylinder 5. The top plate 9 moves and separates from the surface of the metering cylinder 5. At this time, the upper opening of the metering cylinder 5 opens, and the fertilizer granules fall into the metering cylinder 5 under their own weight. Then the movable head 30 is released. The movable head 30 resets under the action of the spring 29, causing the movable rod 15 to reset as well. The reset of the movable rod 15 causes the vertical frame 16 and the retaining ring 18 to reset as well.During the reset process of guide rod 7, top plate 9 resets and blocks the surface of metering cylinder 5, while bottom plate 8 resets and opens the bottom opening of metering cylinder 5. At this time, the fertilizer granules inside metering cylinder 5 fall into rotating cylinder 1 under their own weight, passing through the outlet holes of corrugated pipe 37 and plow blade 36, and into the soil next to the vegetables to be fertilized. According to the amount of fertilizer required by the vegetables, gear 26 rotates, causing rotating gear 4 to rotate, which in turn causes multiple metering cylinders 5 to rotate. When the metering cylinder 5 corresponding to the required amount rotates to the position of retaining ring 18, the knob 27 stops rotating. When plow blade 36 reaches the side of the vegetables to be fertilized, guide rod 7 moves, causing top plate 9 and bottom plate 8 to move. Bottom plate 8 moves and blocks the bottom of metering cylinder 5, while top plate 9 moves and separates from the surface of metering cylinder 5. At this time, the metering cylinder 5... The top opening opens, and fertilizer granules fall into the metering cylinder 5 under their own weight. Then, the guide rod 7 resets, the top plate 9 resets to block the surface of the metering cylinder 5, and the bottom plate 8 resets to open the bottom opening of the metering cylinder 5. At this time, the fertilizer granules inside the metering cylinder 5 fall into the rotating drum 1 under their own weight, and then fall into the soil next to the vegetables being fertilized through the discharge holes of the corrugated pipe 37 and the plow blade 36. Compared with traditional partial fertilization devices, this fertilization device can adjust the metering cylinder 5 according to the amount of fertilizer required by the vegetables, ensuring that the amount of fertilizer required by the vegetables is appropriate. This avoids insufficient fertilizer affecting the growth and development of the vegetables, while also avoiding excessive fertilizer causing burns, thus ensuring the planting and development of the vegetables and ultimately guaranteeing the overall yield.

[0043] Example 2: Please refer to Figure 1 - Figure 12 The difference from the basic embodiment 1 is that the inner sides of both uprights 31 are provided with inner grooves 40, and the inner sides of the two inner grooves 40 are rotatably connected to a rotating column 41. The inner side of the rotating column 41 is fixedly connected to the bottom surface of the rotating cylinder 1. The top of each of the two inner grooves 40 is provided with a detachable mounting block 42. Two fixing rods 43 are symmetrically fixedly installed on the surface of the upper connecting cylinder 2. The surfaces of the two fixing rods 43 are rotatably connected to a rotating frame 44. The bottom surface of the rotating frame 44 is symmetrically rotatably connected to two auxiliary wheels 45, which are used for guidance and assistance.

[0044] Two fixing posts 46 are symmetrically fixedly installed on the bottom surface of the upper connecting cylinder 2. Two slots 47 that engage with the fixing posts 46 are symmetrically opened on the top surface of the rotating cylinder 1. Locking devices 48 for locking the fixing posts 46 are symmetrically provided on the top surface of the rotating cylinder 1. The locking devices 48 are conventional locking devices 48 in the prior art.

[0045] The steps for using this invention are as follows: When using this quantitative fertilization device for vegetable cultivation, during installation, firstly, the rotating column 41 on the surface of the rotating cylinder 1 is inserted into the two inner grooves 40. Then, the mounting block 42 is installed in the inner grooves 40 to limit the rotation column 41. Then, the upper connecting cylinder 2 is attached to the top of the rotating cylinder 1. During the attachment process, firstly, the fixing column 46 on the surface of the upper connecting cylinder 2 is attached into the groove 47. Then, the upper connecting cylinder 2 is rotated clockwise. Finally, the locking device 48 is rotated to lock the surface of the fixing column 46, thereby achieving quick installation of the vegetable fertilization device. It also facilitates quick disassembly of the vegetable fertilization device, making it suitable not only for operation in the limited space of a greenhouse but also for easy transfer and transportation of the vegetable fertilization device.
