Description

Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, specifically a fertilizer applicator. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide them with the nutrients they need and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and enhance economic benefits. Therefore, rational and scientific fertilization is one of the main means of ensuring food security and maintaining sustainable agricultural development. Fertilization usually requires specific equipment.

[0003] When using fertilizer applicators, the connection between the applicator and the housing is often unstable. In actual operation, the applicator is prone to falling off due to bumps and shaking. This not only affects the normal progress of fertilization, leading to uneven fertilization and interruption of the fertilization schedule, but may also damage the applicator, increase maintenance costs, and reduce overall fertilization efficiency and work quality. Utility Model Content

[0004] The purpose of this utility model is to provide a fertilizer applicator that solves the problem of unstable connection between the fertilizer applicator and the housing during use, which can easily cause the fertilizer applicator to fall off during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer applicator, comprising a housing, an installation base fixedly connected inside the housing, a fixing tube fixedly connected inside the installation base, a fertilizer applicator inserted into the outside of the fixing tube, a fixing block fixedly connected to the outside of the installation base, a limit sleeve rotatably connected to the outside of the fixing block, a positioning rod fixedly connected to the outside of the installation base, a positioning plate fixedly connected to the outside of the fertilizer applicator, a cover contacting the upper end of the housing, and a limit mechanism provided on the cover.

[0006] Preferably, the limiting sleeve contacts the mounting base, and the limiting sleeve is connected to the fertilizer applicator via a thread. The design of the limiting sleeve ensures that the fertilizer applicator remains stable after installation.

[0007] Preferably, a protrusion is fixedly connected to the outer side of the fixing block, and the protrusion is slidably connected to the limiting sleeve. Through the design of the protrusion, the limiting sleeve can be limited.

[0008] Preferably, the positioning plate is slidably connected to the positioning rod, and the positioning plate is in contact with the limiting sleeve. Through the design of the positioning plate, it can work with the positioning rod to position the fertilizer applicator.

[0009] Preferably, the limiting mechanism includes a limiting plate, the front of the cover contacts the limiting plate, the front of the box is fixedly connected to a limiting block, a sliding rod is fixedly connected to the side of the limiting plate near the cover, a slider is fixedly connected to the outside of the sliding rod, a limiting frame is fixedly connected inside the cover, and a spring is provided on the outside of the limiting frame. Through the design of the limiting mechanism, the cover can be kept stable when the box moves.

[0010] Preferably, there are two limiting blocks, which are symmetrically distributed on the box. The design of the limiting blocks can be used in conjunction with the limiting plate to limit the blocks.

[0011] Preferably, the limiting plate is in contact with the box body, and the limiting plate is slidably connected to the limiting block. Through the design of the limiting plate, the lid can remain stable after being closed.

[0012] Preferably, the slide rod is slidably connected to the cover, and the slider is slidably connected to the cover. The design of the slide rod and the slider can guide the limiting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting components such as a fixing block, a limiting sleeve, and a positioning rod, enables the limiting sleeve to effectively limit the position of the fertilizer applicator when it is connected to the fixing pipe. Combined with the synergistic effect of the positioning rod and the positioning plate, the fertilizer applicator is precisely fixed in position, ensuring the overall structure is stable after connection. This fundamentally solves the problem of loose connection between the traditional fertilizer applicator and the box and easy detachment during operation, thus improving the reliability of use.

[0017] 2. This utility model sets up components such as a limiting plate, a limiting block, and a spring. The spring force drives the limiting plate and the limiting block to slide and adapt, so that the limiting plate accurately fits the edge of the cover and forms a stable limiting structure. This effectively enhances the tightness and positional stability of the cover and the box after installation, avoids the cover from loosening or accidentally detaching during use, and improves the overall assembly reliability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A fertilizer applicator includes a housing 1. This backpack fertilizer applicator is carried manually and powered by manually squeezing the fertilizer box or by the pressure generated by the movement of the human body while carrying it. If equipped with electric auxiliary power, the motor power is 0.5-1kW (voltage 12V or 24V), mainly used to drive the agitator or assist in pressurization; the housing 1 is internally fixedly connected to the mounting base 2, and the mounting base 2 is internally fixedly connected to the fixing pipe 21. The fertilizer applicator 22 is inserted into the outside of the fixing pipe 21. The nozzle diameter is 2-5mm (suitable for fertilizer granule size); the spray shape is fan-shaped (60°-120°) or conical (30°-90°); the flow rate is adjusted by a knob (0-5L / h), with each adjustment changing the flow rate by 0.5L / h. Anti-clogging design: built-in 200-mesh filter (filtration accuracy 0.1mm). The mounting base 2 is externally fixedly connected to the fixing block 23, and the fixing block 23 is rotatably connected to the limiting sleeve 24. The limiting sleeve 24 contacts the mounting base 2 and is threadedly connected to the fertilizer applicator 22. The design of the limiting sleeve 24 allows the fertilizer applicator 22 to be installed... Afterwards, it remains stable. A protrusion 25 is fixedly connected to the outer side of the fixing block 23. The protrusion 25 is slidably connected to the limiting sleeve 24. Through the design of the protrusion 25, the limiting sleeve 24 can be limited. A positioning rod 26 is fixedly connected to the outer side of the mounting base 2. A positioning plate 27 is fixedly connected to the outer side of the fertilizer applicator 22. The positioning plate 27 is slidably connected to the positioning rod 26. The positioning plate 27 contacts the limiting sleeve 24. Through the design of the positioning plate 27, it can cooperate with the positioning rod 26 to position the fertilizer applicator 22. Fertilizer application rate adjustment: Rotate the handle to adjust the nozzle opening (the scale displays 0.5-5 kg / mu); Spraying angle: Fixed conical spray (adjustable range 30°-90°). The upper end of the box 1 is in contact with the cover 3. The cover 3 is equipped with a limiting mechanism 4. When manually squeezed, the pressure in the fertilizer box is generally 0.1-0.3 MPa; if an electric booster device is configured, the pressure can be adjusted to 0.1-0.5 MPa.

[0026] Please see Figure 2-5 The limiting mechanism 4 includes a limiting plate 41. The front of the cover 3 is in contact with the limiting plate 41. The front of the box 1 is fixedly connected to a limiting block 42. There are two limiting blocks 42, which are symmetrically distributed on the box 1. Through the design of the limiting block 42, it can cooperate with the limiting plate 41 to limit the limiting block 42. The limiting plate 41 is in contact with the box 1 and is slidably connected to the limiting block 42. Through the design of the limiting plate 41, the cover 3 can remain stable after closing. A sliding rod 43 is fixedly connected to the side of the limiting plate 41 near the cover 3. A slider 44 is fixedly connected to the outside of the sliding rod 43. The sliding rod 43 is slidably connected to the cover 3.

[0027] Please see Figure 2-5The slider 44 is slidably connected to the cover 3. The design of the slider 44 and the slide rod 43 can guide the limiting plate 41. The inside of the cover 3 is fixedly connected to the limiting frame 45. The limiting frame 45 is in contact with the slide rod 43, and the limiting frame 45 is slidably connected to the slider 44. The limiting frame 45 is in contact with the limiting plate 41. The design of the limiting frame 45 can limit the limiting plate 41. A spring 46 is provided on the outside of the limiting frame 45. One end of the spring 46 is in contact with the slider 44, and the other end of the spring 46 is in contact with the limiting frame 45. The design of the spring 46 can drive the limiting plate 41 to limit the cover 3. The design of the limiting mechanism 4 can keep the cover 3 stable when the box 1 moves. The flow rate can be adjusted by manually rotating the flow rate adjustment knob. Each rotation of a certain angle (such as 30°) corresponds to a certain change in flow rate (such as 0.1L / h or 0.05kg / h). When adjusting the spray angle, the angle adjustment component of the nozzle is manually moved. Each time the component is moved to a fixed position, the angle changes by a certain value (e.g., 15°).

[0028] The specific implementation process of this utility model is as follows: In use, by inserting the fertilizer applicator 22 into the fixed pipe 21, the fertilizer applicator 22 drives the positioning plate 27 to slide into the positioning rod 26. The positioning plate 27 slides smoothly along the positioning rod 26 to achieve precise guidance and positioning. Then, the limiting sleeve 24 is rotated, so that the limiting sleeve 24 and the fertilizer applicator 22 undergo threaded movement. During the thread tightening process, the limiting sleeve 24 generates axial pressure on the fertilizer applicator 22, thereby limiting the fertilizer applicator 22 and ensuring that the fertilizer applicator 22 remains stably connected after being inserted into the fixed pipe 21, effectively preventing the fertilizer applicator 22 from loosening due to vibration or impact during operation.

[0029] Liquid fertilizer: Moisture content 30%-60%, such as common liquid compound fertilizers with a concentration of 0.5%-2%. When the nozzle diameter is 3mm and the pressure is 0.2MPa, the flow rate adjustment range is 1-3L / h, resulting in good fertilization uniformity. Suspension of powdered fertilizer mixed with liquid: Fertilizer particle size 0.1-1mm, moisture content 40%-70%. Nozzle diameter 4-5mm, pressure 0.3-0.5MPa, flow rate adjustment range 1-2kg / h.

[0030] By moving the limiting plate 41 away from the box 1, the limiting plate 41 drives the sliding rod 43 to move. The sliding rod 43 pushes the slider 44 to move smoothly on the limiting frame 45. During the movement, the slider 44 compresses and stores energy in the spring 46, causing the limiting plate 41 to slide off the limiting block 42, releasing the limitation on the cover 3. The cover 3 can then be opened to feed material into the box 1. The operation is simple and quick. At the same time, the spring 46 ensures that the cover 3 can automatically reset and fit tightly against the box 1 when closed, ensuring the sealing of the box 1 and preventing fertilizer leakage.

[0031] Uniformity: The coefficient of variation for fertilizer application is ≤10% (for liquid fertilizers) or ≤15% (for suspension fertilizers), which is better than the industry standard (the general industry standard is a coefficient of variation of ≤15%).

[0032] Anti-clogging performance: No clogging after 3 hours of continuous operation (the average clogging frequency of traditional similar nozzle-type fertilizer applicators is 1-2 times / hour). Through the effective combination of the filtration device and the anti-clogging agitator, the probability of clogging is greatly reduced.

[0033] Sealing: The leakage rate of the fertilizer tank is ≤0.1% (achieved through sealing rings and reasonable structural design), ensuring that the fertilizer solution will not leak and guaranteeing the normal operation of fertilization.
