Description

Technical Field

[0001] This utility model relates to the field of equipment technology for vegetable planting, and in particular to a quantitative fertilization device for vegetable planting. Background Technology

[0002] In vegetable cultivation, fertilization is a crucial step in ensuring healthy crop growth and improving yield and quality. Its core purpose is to replenish nutrients in the soil that have been absorbed by crops or lost naturally, to meet the diverse nutrient requirements of different vegetable varieties, and to maintain soil fertility and ecological balance, thereby achieving sustainable agricultural development.

[0003] Most commercially available quantitative fertilization devices currently use a drum structure with multiple protruding fertilizer storage chambers on the drum surface. During operation, these chambers are inserted into the soil, and a mechanism opens and closes to release the fertilizer quantitatively into the soil. However, this existing equipment has certain limitations: firstly, the fertilizer application rate adjustment mechanism is fixed, making it difficult to flexibly adjust according to the nutrient requirements of different vegetable varieties; secondly, during the opening and closing of the chambers inside the soil, soil can easily enter the joints, causing jamming and affecting the stability and accuracy of the device.

[0004] Therefore, it is necessary to propose a quantitative fertilization device for vegetable cultivation. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a quantitative fertilization device for vegetable planting.

[0006] The technical solution is as follows: A quantitative fertilization device for vegetable cultivation includes a gripping rod, a connecting ring, an insertion cone, a guide shell, a top cover, a mounting shell, a motor, a quantitative wheel, and fastening bolts. The gripping rod has a longitudinally extending guide channel inside it, and a top cover is threaded onto the top of the gripping rod. A connecting ring is connected to the bottom of the gripping rod, and the bottom of the connecting ring is connected to the insertion cone. A groove communicating with the guide channel is opened inside the insertion cone, and the opening of the groove is located on one side of the insertion cone, allowing fertilizer entering from the guide channel to be discharged through the connecting ring and then through the groove. A guide shell is slidably mounted on the insertion cone, and the groove is located inside the guide shell. A mounting shell is mounted on the connecting ring, and a motor is mounted on the mounting shell. A quantitative wheel located inside the mounting shell is keyed to the output end of the motor. A fastening bolt is threaded onto the quantitative wheel, and the end of the fastening bolt is threaded to the output end of the motor.

[0007] Furthermore, it also includes guide sleeves, a movable frame, and movable wheels. Guide sleeves are provided on both sides of the connecting ring, and a movable frame is slidably arranged between the two guide sleeves. The movable frame is also slidably connected to the grip rod, and movable wheels are symmetrically arranged at the bottom of the movable frame.

[0008] Furthermore, it also includes a plug rod, with the plug rod inserted between the two guide sleeves, and the plug rod is also plugged into the movable frame.

[0009] Furthermore, it also includes a support plate, and the bottom of the movable frame is also provided with a support plate, which is arranged opposite to the movable wheels.

[0010] Furthermore, it also includes an acrylic plate, which is installed on the grip rod to observe the condition inside the material guide channel.

[0011] Furthermore, anti-slip grooves are arranged on the support plate.

[0012] Beneficial effects: This utility model uses a motor to drive a grooved metering wheel to rotate, achieving precise adjustment of the fertilizer output per unit time, thereby accurately controlling the amount of fertilizer applied. This design can meet the nutrient requirements of different vegetable varieties and growth stages, and supports the application of single or mixed fertilizers, making it highly versatile. At the same time, by adjusting the motor frequency, the fertilizer application speed and dosage can be flexibly controlled, adapting to various soil and crop types. Furthermore, the fertilizer transmission uses a closed material guide channel in conjunction with the metering wheel, avoiding the problem of traditional structures being easily blocked by soil, thus improving the stability and service life of the equipment.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example: A quantitative fertilization device for vegetable cultivation, such as... Figures 1-5 As shown, the device includes a gripping rod 1, a connecting ring 2, an insertion cone 3, a guide shell 4, a top cover 6, a mounting shell 7, a motor 8, a metering wheel 9, and fastening bolts 10. The gripping rod 1 is a supporting structure with a longitudinally extending guide channel 5 inside for storing and guiding fertilizer downwards. A screw-on top cover 6 is threaded onto the top of the gripping rod 1, allowing for sealing or opening of the guide channel 5, facilitating the addition of different types or mixtures of fertilizer as needed. A connecting ring 2 is connected to the bottom of the gripping rod 1, and the bottom of the connecting ring 2 is connected to the insertion cone 3. The insertion cone 3 has a groove communicating with the guide channel 5, with the groove opening located on one side of the insertion cone 3. The fertilizer can smoothly enter the insertion cone 3 from the guide channel 5 via the connecting ring 2, and finally be output through its trough. A guide shell 4 is slidably set on the insertion cone 3, and the trough is located in the internal space of the guide shell 4. This is used to prevent the fertilizer from shifting or scattering during the fall, and to ensure the accuracy and concentration of the fertilization position. An installation shell 7 is set on the connecting ring 2. A motor 8 is installed on the installation shell 7. A metering wheel 9 located inside the installation shell 7 is keyed to the output end of the motor 8. The surface of the metering wheel 9 has multiple evenly distributed grooves, which are used to realize the gradual dispensing and precise control of fertilizer. In addition, a fastening bolt 10 is also installed on the metering wheel 9. Its end is threadedly connected to the output shaft of the motor 8 to enhance the transmission stability and prevent slippage or displacement during operation.

[0022] Therefore, the design of the holding rod 1 and the material guiding channel 5, as the core material storage and guiding structure of the entire device, ensures that the fertilizer can flow smoothly from top to bottom, avoiding blockage problems and thus significantly improving the feeding efficiency. At the same time, the design of the material guiding shell 4 not only improves the positioning accuracy of fertilizer application, but also effectively prevents fertilizer from overflowing or being affected by wind, avoiding the problem of traditional structures being easily blocked by soil, thus ensuring the quality of fertilizer application.

[0023] Furthermore, the combination of motor 8 and metering wheel 9 enables automated quantitative fertilization. By adjusting the speed of motor 8, the amount of fertilizer applied each time can be flexibly controlled to adapt to the needs of different crop types and soil conditions. This design not only improves the accuracy and flexibility of fertilization but also enhances the equipment's adaptability to various agricultural scenarios.

[0024] like Figure 1 and Figure 6As shown, the device also includes guide sleeves 11, a movable frame 12, and movable wheels 14. Guide sleeves 11 are fixedly installed on both sides of the connecting ring 2, and a movable frame 12 is slidably installed between the two guide sleeves 11. The movable frame 12 is also slidably connected to the gripping rod 1, and can slide up and down along the guide sleeves 11. Movable wheels 14 are symmetrically installed on the bottom of the movable frame 12. Through the sliding design between the movable frame 12 and the guide sleeves 11, users can flexibly adjust the placement height of the equipment according to actual terrain conditions, improving the adaptability and ease of operation of the device. At the same time, the movable wheels 14 enable easy movement of the fertilizer applicator in the field, effectively reducing the intensity of manual handling and significantly improving work efficiency.

[0025] like Figure 6 As shown, it also includes a plug rod 13, which is inserted between the two guide sleeves 11. The plug rod 13 is also plugged into the movable frame 12. This structural design can effectively prevent the movable frame 12 from shaking or shifting during use, thereby enhancing the stability and operational safety of the equipment in complex environments.

[0026] like Figure 6 As shown, it also includes a support plate 15. The bottom end of the movable frame 12 is also provided with a support plate 15 as an auxiliary support structure when the device is stationary. Anti-slip grooves 17 are arranged on the support plate 15. The anti-slip grooves 17 can increase the friction between the support plate 15 and the ground. The support plate 15 and the movable wheel 14 are arranged opposite to each other, so that the two can be used selectively.

[0027] like Figure 2 As shown, it also includes an acrylic plate 16, which is provided on the gripping rod 1 for observing the inside of the material guide channel 5.

[0028] When using this device, first rotate the top cover 6 to separate it from the holding rod 1 via threads, allowing the desired fertilizer to be injected into the feed channel 5 of the holding rod 1. Depending on the actual fertilization needs, a single type or a mixture of fertilizers can be injected. After injection, tighten the top cover 6 to seal the opening of the feed channel 5. Next, move the device to the designated fertilization area and ensure the insertion cone 3 is inserted into the soil. Then, start the motor 8, which drives the metering wheel 9 to rotate. As the metering wheel 9 rotates, the grooves on it align sequentially with the bottom of the feed channel 5, allowing the fertilizer to fall into the grooves under gravity. As the metering wheel 9 continues to rotate, the grooves containing fertilizer flip to the lower position, aligning with the groove of the insertion cone 3. The fertilizer then slides into this groove and falls into the feed housing 4 for subsequent fertilization processing. Furthermore, the rotation frequency of the motor 8 can be adjusted according to actual needs, thereby controlling the amount of fertilizer delivered to the feed housing 4 each time. When fertilization is needed, pulling up the holding rod 1 raises the connecting ring 2 and the insertion cone 3 together, causing the tip of the insertion cone 3 to disengage from the outlet of the guide shell 4. The fertilizer then loses its support and falls smoothly to the ground. Following this procedure, fertilizer can be evenly spread over the target area as needed, completing the fertilization process in vegetable cultivation. After use, the device is tilted and easily moved to its storage location using the casters 14. Upon arrival, the insertion rod 13 is pulled out, and the moving frame 12 slides down the guide sleeve 11 until the bottom of the moving frame 12 is below the insertion cone 3. Then, the device is tilted towards the support plate 15, using the support plate 15 as a fulcrum to ensure stable placement.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
