Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer application technology, and in particular, it is an organic fertilizer application device for crop growth. Background Technology

[0002] Organic fertilizer application devices are essential mechanical equipment in modern agricultural production for the precise and efficient application of organic fertilizers into the soil. Compared to traditional manual spreading or simple scattering methods, modern organic fertilizer application devices are designed to solve problems such as poor dispensing and uneven distribution caused by the high water content, sticky texture, and tendency to clump organic fertilizers. These devices are widely used in orchards, vegetable gardens, field crops, and facility agriculture. Their role is becoming increasingly prominent, especially in the context of promoting green and ecological planting and increasing soil organic matter content. Organic fertilizers, due to their rich humus content, improved soil structure, and promotion of microbial activity, play an increasingly important role in the sustainable development of modern agriculture.

[0003] However, compared with chemical fertilizers, organic fertilizers generally have high moisture content (usually between 25% and 40%), viscous texture, high fiber content, and are prone to absorbing moisture and clumping. These characteristics pose a significant challenge to mechanized fertilization. Currently, most organic fertilizer applicators on the market adopt the structural design of chemical fertilizer applicators, failing to fully consider the unique physical properties of organic fertilizers. This leads to a series of serious technical defects in practical applications, severely affecting fertilization efficiency, operational continuity, and fertilization uniformity. For example, existing fertilization devices generally use a static hopper combined with a single stirring shaft or screw conveyor, lacking an effective dynamic screening mechanism, which easily causes "bridging blockage." "Bridging" refers to the formation of a stable arched structure above the hopper outlet when strong cohesion occurs between organic fertilizer particles due to the action of moisture and organic colloids, preventing the fertilizer below from falling further. This type of equipment relies solely on gravity feeding and the shearing action of the rotating agitator shaft. However, the agitator shaft rotates at a relatively low speed, resulting in limited shearing force, which is insufficient to effectively break up large clumps. Furthermore, the hopper itself remains stationary, leaving the material in a relatively static, piled-up state with little lateral disturbance. This makes it difficult for viscous materials to disintegrate once they form a stable structure. If this problem remains unresolved for an extended period, it will not only significantly reduce fertilization efficiency and increase manual intervention costs, but may also lead to severely uneven fertilization—no fertilizer is discharged during blockages, but a large amount is suddenly discharged after unblocking, resulting in localized over-fertilization. Utility Model Content

[0004] The purpose of this invention is to provide an organic fertilizer application device for crop growth, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an organic fertilizer application device for crop growth, comprising:

[0006] The fertilizer outer sleeve has a removable and replaceable fertilizer inner funnel inside.

[0007] The mixing and crushing device is mounted above the center of the fertilizer outer cylinder and its free drive end extends into the fertilizer inner hopper.

[0008] The positioning support crossbar is detachably and symmetrically installed in the fertilizer outer sleeve and extends laterally through the fertilizer inner liner funnel, so that the fertilizer inner liner funnel can slide linearly in the inner cavity of the fertilizer outer sleeve along the lateral extension direction of the positioning support crossbar, thereby sieving organic fertilizer.

[0009] The elastic reset component is arranged parallel to the positioning support crossbar, with one end connected to the inner wall of the fertilizer outer sleeve and the other end elastically abutting against the outer wall of the opposite fertilizer inner funnel.

[0010] The reciprocating drive mechanism is arranged opposite to the elastic reset member. Its drive end reciprocates and impacts the outer wall of the fertilizer inner liner funnel on the other side, so that the fertilizer inner liner funnel is driven to slide back and forth between the elastic reset member and the reciprocating drive mechanism.

[0011] A safe space is reserved between the two positioning support crossbars for the mixing and crushing device to mix.

[0012] In this preferred embodiment, the fertilizer outer sleeve has a square tube-shaped structure, the fertilizer inner liner funnel is installed inside it, the bottom end of the fertilizer inner liner funnel is integrally connected to a fertilizer dispensing pipe, and a dispensing control component is installed inside the fertilizer dispensing pipe.

[0013] In this preferred embodiment, two positioning holes are symmetrically opened on the outer walls of both sides of the top of the fertilizer inner liner funnel for the positioning support crossbars to pass through, and the elastic reset component includes a reset spring symmetrically sleeved on the same end of the two positioning support crossbars.

[0014] In this preferred embodiment, the two positioning support crossbars pass through the positioning holes to support the fertilizer inner liner funnel, and both ends of the positioning support crossbars are fixed to the inner wall of the fertilizer outer sleeve by bolts. One end of each of the return springs abuts against the inner wall of the fertilizer outer sleeve, and the other end abuts against the outer wall of the fertilizer inner liner funnel.

[0015] In a preferred embodiment, the reciprocating drive mechanism includes a support base installed on the inner wall of the fertilizer applicator outer sleeve, a servo motor installed on the top surface of the support base, and an eccentric wheel installed on the output shaft of the servo motor. The eccentric end of the eccentric wheel reciprocates against the outer wall of the fertilizer applicator inner funnel, driving the fertilizer applicator inner funnel to move toward one side of the elastic reset member. Under the elastic reaction force of the elastic reset member, the fertilizer applicator inner funnel is driven to reset toward the reciprocating drive mechanism.

[0016] In a preferred embodiment, the mixing and crushing device includes a mixing shaft suspended and extending into the fertilizer inner liner funnel, a mixing motor that drives the mixing shaft to rotate, a first crushing blade located in the upper part of the inner cavity of the fertilizer inner liner funnel and installed on the outer wall of the mixing shaft, and a second crushing blade located in the lower part of the inner cavity of the fertilizer inner liner funnel and installed on the outer wall of the mixing shaft.

[0017] In this preferred embodiment, the crushing diameter range of the first and second crushing blades is adapted and adjusted according to the inner cavity diameter of the fertilizer inner liner funnel. The mixing crusher also includes an inverted U-shaped hoisting frame mounted on the outside of the fertilizer outer sleeve. The mixing motor is installed in the middle of the top surface of the U-shaped hoisting frame, and the mixing shaft is rotatably mounted on the top of the U-shaped hoisting frame and connected to the output shaft of the mixing motor.

[0018] In a preferred embodiment of this scheme, the fertilization device further includes a vehicle frame platform, which includes a vehicle bottom frame, a support frame installed at one end of the top surface of the vehicle bottom frame, a push handle installed at one end of the vehicle bottom frame, an electrical distribution box installed at the other end of the top surface of the vehicle bottom frame, and wheels installed at the four corners of the bottom surface of the vehicle bottom frame.

[0019] In this preferred embodiment, both outer walls of the fertilizer inner liner funnel are fixed with lifting rings, each lifting ring is fixed with a lifting rope, and the bottom end of each lifting rope is fixed with an impact ball. Each impact ball is located in the gap between the bottom outer wall of the fertilizer inner liner funnel and the inner wall of the fertilizer outer sleeve, and the outer wall of the impact ball is covered with a silicone sleeve.

[0020] In a preferred embodiment, the feeding control component includes a feeding wheel that is rotatably disposed in the inner cavity of the fertilizer feeding pipe, a plurality of quantitative feeding grooves arranged in a ring array on the outer wall of the feeding wheel, and a feeding motor installed on the outer wall of the fertilizer feeding pipe and connected to the central shaft of the feeding wheel for driving. The other end of the central shaft of the feeding wheel is connected to the fertilizer feeding pipe through a sealed bearing.

[0021] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0022] This organic fertilizer application device for crop growth utilizes a detachable and replaceable inner hopper funnel installed inside the outer hopper. A positioning support crossbar symmetrically runs through the inner cavity of the outer hopper, allowing the inner hopper funnel to slide linearly laterally under the guidance of the crossbar, thus achieving dynamic sieving of the organic fertilizer. Simultaneously, an elastic reset component and a reciprocating drive mechanism are positioned on either side of the inner hopper funnel and arranged opposite each other, driving it to reciprocate linearly between the two components. This creates a high-frequency vibrating sieving mechanism, causing the accumulated organic fertilizer to continuously loosen and flow under the combined effects of gravity and vibration. This effectively prevents bridging and clogging caused by high humidity and high viscosity. Compared to existing technologies that rely solely on gravity or simple stirring, this significantly improves the stability and continuity of the feeding process, achieving the beneficial effects of preventing clogging and ensuring continuous fertilization.

[0023] By installing a mixing and crushing device above the center of the fertilizer inner liner funnel and extending it suspended into the funnel, the mixing motor drives the first and second crushing blades to perform multi-stage crushing at different heights. This results in the organic fertilizer being subjected to both active impact from the vibrating screen and forced shearing and dispersing by the high-speed rotating blades during its descent, forming a dual crushing mode of "passive crushing + active impact." In particular, when the fertilizer inner liner funnel slides back and forth, causing the fertilizer particles to periodically impact the rotating crushing blades, the crushing efficiency is further enhanced. This method is especially suitable for processing organic fertilizers containing fibers and with severe agglomeration, avoiding the problems of insufficient crushing capacity and easy entanglement and jamming of traditional single mixing devices. It achieves the functions of efficient crushing and uniform mixing, significantly improving the dispersion uniformity and feeding smoothness of organic fertilizers compared with existing technologies, thus achieving the beneficial effects of improving fertilization quality and operational efficiency.

[0033] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0034] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0035] This embodiment provides, for example Figures 1 to 6 The device shown is an organic fertilizer application device for crop growth, comprising: a fertilizer application outer sleeve 1, a mixing and crushing device 3, a positioning support crossbar 4, an elastic reset component 5, and a reciprocating drive mechanism 6.

[0036] In this embodiment, a detachable and replaceable fertilizer inner liner funnel 2 is movably installed inside the fertilizer outer sleeve 1; the stirring and crushing device 3 is mounted above the center of the fertilizer outer sleeve 1 and its free drive end extends into the fertilizer inner liner funnel 2; the positioning support crossbars 4 are detachably and symmetrically installed in the fertilizer outer sleeve 1 and both transversely penetrate the fertilizer inner liner funnel 2, so that the fertilizer inner liner funnel 2 can slide linearly in the inner cavity of the fertilizer outer sleeve 1 along the transverse extension direction of the positioning support crossbars 4 to screen the organic fertilizer; the elastic reset member 5 The positioning support crossbar 4 is arranged parallel to the fertilizer outer sleeve 1, with one end connected to the inner wall of the fertilizer outer sleeve 1 and the other end elastically abutting against the outer wall of the opposite fertilizer inner liner funnel 2. The reciprocating drive mechanism 6 is arranged opposite to the elastic reset member 5, and its driving end reciprocates against the other outer wall of the fertilizer inner liner funnel 2, causing the fertilizer inner liner funnel 2 to be driven to slide back and forth between the elastic reset member 5 and the reciprocating drive mechanism 6. This allows the fertilizer inner liner funnel 2 to move back and forth between the elastic reset member 5 and the reciprocating drive mechanism 6 to screen the organic fertilizer. This not only prevents the organic fertilizer from clogging, but also allows the screened fertilizer to collide with the mixing and crushing device 3. Through the active collision of the fertilizer with the mixing and crushing device 3 and the passive mixing and crushing by the mixing and crushing device 3, the feeding efficiency is improved, agglomeration is prevented, and the mixing of organic fertilizer is improved. A safe space is reserved between the two positioning support crossbars 4 for the mixing and crushing device 3 to stir.

[0037] In this embodiment, the fertilizer outer sleeve 1 has a square tube-shaped structure, and the fertilizer inner funnel 2 is installed inside it. The bottom end of the fertilizer inner funnel 2 is integrally connected to the fertilizer feeding pipe 30, and the fertilizer feeding pipe 30 is equipped with a feeding control component inside.

[0038] In this embodiment, two positioning holes 21 are symmetrically opened on the outer walls of both sides of the top of the fertilizer inner liner funnel 2 for the positioning support crossbar 4 to pass through. The elastic reset component 5 includes a reset spring 19 symmetrically sleeved on the same end of the two positioning support crossbars 4.

[0039] In this embodiment, two positioning support crossbars 4 pass through the positioning through holes 21 to support the fertilizer inner funnel 2, and both ends of the positioning support crossbars 4 are fixed to the inner wall of the fertilizer outer sleeve 1 by bolts. One end of each return spring 19 abuts against the inner wall of the fertilizer outer sleeve 1, and the other end abuts against the outer wall of the fertilizer inner funnel 2.

[0040] In this embodiment, the reciprocating drive mechanism 6 includes a support base 25 installed on the inner wall of the fertilizer outer sleeve 1, a servo motor 26 installed on the top surface of the support base 25, and an eccentric wheel 27 installed on the output shaft of the servo motor 26. The eccentric end of the eccentric wheel 27 reciprocates against the outer wall of the fertilizer inner funnel 2, driving the fertilizer inner funnel 2 to move toward one side of the elastic reset member 5. Under the elastic reaction force of the elastic reset member 5, the fertilizer inner funnel 2 is driven to reset toward the reciprocating drive mechanism 6.

[0041] In this embodiment, the mixing and crushing device 3 includes a mixing shaft 17 suspended and extending into the fertilizer inner liner funnel 2, a mixing motor 15 that drives the mixing shaft 17 to rotate, a first crushing blade 18 located in the upper part of the inner cavity of the fertilizer inner liner funnel 2 and installed on the outer wall of the mixing shaft 17, and a second crushing blade 33 located in the lower part of the inner cavity of the fertilizer inner liner funnel 2 and installed on the outer wall of the mixing shaft 17.

[0042] In this embodiment, the crushing diameter range of the first crushing blade 18 and the second crushing blade 33 is adapted and adjusted according to the inner cavity diameter of the fertilizer inner liner funnel 2, so that the stirring and crushing diameter of the second crushing blade 33 is smaller than the stirring and crushing diameter range of the first crushing blade 18. The stirring crusher 3 also includes an inverted U-shaped hoisting frame 14 mounted on the outside of the fertilizer outer sleeve 1, the stirring motor 15 is installed in the middle of the top surface of the U-shaped hoisting frame 14, and the stirring shaft 17 is rotatably mounted on the top of the U-shaped hoisting frame 14 and connected to the output shaft of the stirring motor 15.

[0043] In this embodiment, the fertilizing device further includes a frame platform 7, which includes a chassis frame 8, a support frame 9 mounted on one end of the top surface of the chassis frame 8, a push handle 10 mounted on one end of the chassis frame 8, a distribution box 12 mounted on the other end of the top surface of the chassis frame 8, and wheels 11 mounted on the four corners of the bottom surface of the chassis frame 8. A support flange 16 is welded to the outer wall of the fertilizing outer sleeve 1. The support flange 16 is bolted to the top surface of the support frame 9, allowing the fertilizing outer sleeve 1 to be inserted longitudinally into the support frame 9, thus enabling the support flange 16 to support the fertilizing outer sleeve 1 on the support frame 9. Multiple operation buttons 13 are provided on the push handle 10, each button 13 controlling the opening and closing of each motor. The distribution box 12 contains a rechargeable battery to power each motor. A junction box 20 for wiring the servo motor 26 is installed behind the servo motor 26 and on the outer wall of the fertilizing outer sleeve 1. Both ends of the bottom of the U-shaped hoisting frame 14 are welded to the top surface of the support flange 16 and the outer wall of the fertilizer outer sleeve 1.

[0044] In this embodiment, hanging rings 22 are fixed to both outer walls of the fertilizer inner funnel 2, and a hanging rope 23 is fixed to each hanging ring 22. An impact ball 24 is fixed to the bottom end of each hanging rope 23. Each impact ball 24 is located in the gap between the bottom outer wall of the fertilizer inner funnel 2 and the inner wall of the fertilizer outer sleeve 1. When the fertilizer inner funnel 2 is driven to move back and forth, the suspended impact ball 24 swings back and forth and impacts the bottom outer wall of the fertilizer inner funnel 2, thereby physically striking the outer wall of the fertilizer inner funnel 2, reducing bottom blockage and fertilizer adhesion to the inner wall of the fertilizer inner funnel 2. The outer wall of the impact ball 24 is covered with a silicone sleeve to reduce noise. By installing hanging rings 22, hanging ropes 23, and impact balls 24 suspended at the bottom on the outer walls of both sides of the fertilizer inner liner funnel 2, and by having the impact balls 24 swing back and forth during their reciprocating sliding, the impact balls 24 periodically impact the bottom outer wall of the fertilizer inner liner funnel 2, forming a physical knocking and unblocking mechanism. This effectively shakes off the wet and sticky fertilizer adhering to the inner wall of the funnel, especially near the discharge port, reducing the frequency of manual cleaning. At the same time, the impact balls 24 are wrapped with silicone sleeves, which reduces the noise generated by metal collisions and improves the working environment. This achieves the dual functions of automatic unblocking and noise reduction. Compared with existing technologies that rely on manual knocking or pneumatic unblocking devices, this technology has a simpler structure, lower cost, and is easier to maintain, achieving the beneficial effects of energy saving, environmental protection, and improved operating comfort.

[0045] In this embodiment, the feeding control component includes a feeding wheel 31 rotatably disposed within the inner cavity of the fertilizer feeding pipe 30, a plurality of quantitative feeding grooves 32 arranged in a ring array on the outer wall of the feeding wheel 31, and a feeding motor 28 installed on the outer wall of the fertilizer feeding pipe 30 and connected to the central shaft of the feeding wheel 31 for driving. The other end of the central shaft of the feeding wheel 31 is connected to the fertilizer feeding pipe 30 via a sealed bearing 29. A spacer protrusion is provided between adjacent quantitative feeding grooves 32, and the curved outer wall of the spacer protrusion rubs against the inner wall of the fertilizer feeding pipe 30. When the spacer protrusion rubs against the inner wall of the fertilizer feeding pipe 30, feeding is closed. When the feeding wheel 31 rotates, fertilizer is carried in the quantitative feeding grooves 32, and the quantitative feeding grooves 32 are not in contact with the inner wall of the fertilizer feeding pipe 30, feeding is open.

[0046] Working principle

[0047] This organic fertilizer application device for crop growth involves pouring organic fertilizer into the inner funnel 2. When the servo motor 26 is powered on, it drives the eccentric wheel 27 to rotate. The eccentric mass of the eccentric wheel generates a periodic centrifugal force, causing its edge to continuously impact one side of the outer wall of the inner funnel 2. A return spring 19 is mounted on the positioning support crossbar 4. When the eccentric wheel impacts, the inner funnel 2 overcomes the spring force and slides to one side. When the eccentric wheel passes its highest point, the impact force disappears, the return spring 19 releases its stored energy, and pushes the inner funnel 2 to rebound in the opposite direction. Guided by the positioning support crossbar 4, the inner funnel 2 performs reciprocating linear motion, creating a high-frequency vibration effect. This continuously shakes and loosens the accumulated organic fertilizer inside, effectively preventing clumping and blockage of the discharge port. As the fertilizer hopper 2 moves back and forth, the suspension ropes 23 on both sides cause the impact ball 24 to swing. The impact ball 24 periodically strikes the outer wall at the bottom of the hopper, further preventing sticky fertilizer from adhering to the inner wall or accumulating at the outlet. The impact ball, wrapped in a silicone sleeve, also reduces metal collision noise and improves operating comfort.

[0048] The stirring motor 15 starts, and the power is transmitted to the stirring shaft 17 through the U-shaped hoisting frame 14, causing it to rotate. The first crushing blade 18 at the top is located in the upper section of the funnel and is responsible for the initial cutting and breaking up of large clumps of organic fertilizer. The second crushing blade 33 at the bottom has a smaller diameter and is adapted to the contraction area at the bottom of the funnel. It performs secondary fine crushing as the fertilizer flows downward. A safety space is reserved between the two positioning support crossbars 4 to ensure that the stirring shaft 17 and its blades do not interfere with the crossbars when rotating. During the vibrating screening process, the fertilizer particles actively collide with the rotating crushing blades and are also forcibly stirred and broken up by the blades, forming a dual action mechanism of "active impact + passive crushing", which significantly improves the crushing efficiency and is especially suitable for organic fertilizers with high moisture content and easy sticking.

[0049] The feeding motor 28 drives the feeding wheel 31 to rotate. The feeding wheel 31 is installed inside the fertilizer feeding pipe 30. Its outer wall is provided with multiple quantitative feeding grooves 32, which are distributed in a ring array. When a quantitative feeding groove 32 rotates, it contains a certain volume of fertilizer. As the feeding wheel 31 continues to rotate, the quantitative feeding groove 32 carries the fertilizer into the discharge channel. The spacer protrusions between adjacent quantitative feeding grooves 32 fit tightly against the inner wall of the pipe during rotation, forming a sealing area to prevent the fertilizer from flowing out continuously, thus realizing "intermittent quantitative discharge". By controlling the speed of the feeding motor 28, the amount of fertilizer discharged per unit time can be adjusted. By changing the feeding wheel with different groove volumes, the needs of different fertilizer application rates can be matched.

[0050] Operators push the equipment forward while applying fertilizer, achieving a continuous operation mode of applying fertilizer while moving.
