[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated pesticide and fertilizer coating device, comprising a rotary coating machine and a base, wherein a feeding buffer mechanism is provided on the left side of the rotary coating machine.

[0025] Example 1
[0026] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an integrated pesticide and fertilizer coating device, including a rotary coating machine 1 and a base 2. A feeding buffer mechanism 3 is provided on the left side of the rotary coating machine 1.
[0027] The feeding buffer mechanism 3 includes a box 31. The right side of the box 31 is fixedly connected to the base 2. Buffer components 32 are provided at the top and bottom of the inner cavity of the box 31. An angle adjustment component 33 that works in conjunction with the buffer components 32 is provided on the front side of the box 31.
[0028] Specifically, by setting up the buffer component 32, the fertilizer can be buffered when it is fed, so as to avoid the fertilizer particles from breaking and affecting subsequent processing or application.
[0029] By setting up an angle adjustment mechanism, the angle of the buffer component 32 can be flexibly adjusted to facilitate the buffering and feeding of granular fertilizers of different sizes.
[0030] Furthermore, when fertilizer falls from a height, the buffer component 32 inside the box 31 can directly buffer it, reduce the impact force during the fall, prevent fertilizer particles from breaking due to violent impact, and ensure the uniformity of fertilizer particle size.
[0031] Meanwhile, the tilt angle adjustment component 33 allows for flexible adjustment of the tilt angle of the buffer component 32, which can accommodate fertilizer particles of different sizes. For large particles, the tilt angle can be adjusted to optimize the buffer path and disperse greater impact force. For small particles, the tilt angle can be adjusted to avoid accumulation and blockage, ensuring stable buffering effect under various working conditions.
[0032] Example 2
[0033] The second embodiment of this utility model provides an integrated fertilizer and pesticide coating device. The buffer assembly 32 includes a buffer plate 321. A sponge pad 322 is fixedly connected to the inner side of the buffer plate 321. A rotating shaft 323 is fixedly connected to the front side of the buffer plate 321. A gear 324 is provided on the front side of the rotating shaft 323.
[0034] The rear side of the buffer plate 321 is rotatably connected to the inner wall of the housing 31, and the front side of the rotating shaft 323 passes through the housing 31 and extends to the outer side of the housing 31 to be fixedly connected to the gear 324.
[0035] Specifically, by setting up a buffer plate 321 and a sponge pad 322, the sponge pad 322 on the inner side of the buffer plate 321 is elastic and can directly absorb the impact force when the fertilizer particles fall, reduce particle breakage caused by rigid collision, ensure the uniformity of fertilizer particle size, and facilitate subsequent processing or application.
[0036] By setting gear 324 and rotating shaft 323, the buffer plate 321 and sponge pad 322 can be driven to rotate synchronously, and the tilt angle of the buffer plate 321 and sponge can be adjusted.
[0037] Furthermore, when the fertilizer falls from a height into the box 31, it first comes into contact with the sponge pad 322 on the inner side of the buffer plate 321. The sponge pad 322 on the inner side of the buffer plate 321 absorbs part of the impact force through its own elastic deformation, thus buffering the fertilizer particles and preventing them from breaking due to violent impact.
[0038] Meanwhile, the tilt adjustment component 33 drives the gear 324 to rotate, and drives the buffer plate 321 and the sponge pad 322 to rotate synchronously through the rotating shaft 323, thereby flexibly adjusting the tilt angle of the buffer plate 321 and the sponge pad 322 to adapt to fertilizer particles of different sizes.
[0039] Example 3
[0040] The third embodiment of this utility model provides an integrated fertilizer and pesticide coating device. The tilt adjustment component 33 includes a servo motor 331. The rear side of the servo motor 331 is fixedly connected to the housing 31. The output end of the servo motor 331 is fixedly connected to a screw 332. A lifting plate 333 is sleeved on the surface of the screw 332 and threadedly connected to the lifting plate 333. A rack 334 is fixedly connected to both the left and right sides of the lifting plate 333. The side of the rack 334 away from the lifting plate 333 meshes with a gear 324.
[0041] Support plates 4 are fixedly connected to the top and bottom of the front side of the housing 31. The top of the screw 332 passes through the bottom support plate 4 and extends to the inside of the two support plates 4, where it is rotatably connected to the top support plate 4.
[0042] Limiting posts 5 are fixedly connected to both sides of the opposite side of the two support plates 4, and the two sides of the lifting plate 333 are respectively sleeved on the surface of the two limiting posts 5.
[0043] Specifically, the lifting distance of the lifting plate 333 can be precisely controlled by the servo motor 331 driving the screw 332, and the tilt angle of the buffer plate 321 can be precisely adjusted by the meshing of the rack 334 and the gear 324.
[0044] By setting the support plate 4 and the limiting post 5, the lifting plate 333 is sleeved on the limiting post 5 on both sides, which restricts the lateral sway and ensures that the vertical movement of the lifting plate 333 is stable. At the same time, the support plate 4 provides fixed support for the screw 332 to prevent the screw 332 from deviating when rotating.
[0045] Furthermore, when it is necessary to adjust the tilt angle of the buffer plate 321, the servo motor 331 starts and drives the screw 332 at the output end to rotate. Since the screw 332 is connected to the lifting plate 333 by a thread, and the two sides of the lifting plate 333 are sleeved on the limit post 5, the rotational freedom is restricted. The rotational motion of the screw 332 is converted into the vertical lifting motion of the lifting plate 333. The racks 334 on both sides of the lifting plate 333 rise and fall synchronously with the lifting plate 333. The racks 334 mesh with the gear 324 on the front side of the rotating shaft 323 of the buffer assembly 32, thereby driving the gear 324 and the rotating shaft 323 to rotate. Finally, the buffer plate 321 rotates around the rotating shaft 323 as the center, changing its own tilt angle.
[0046] Working principle:
[0047] During the fertilizer feeding stage, the fertilizer granules processed by the rotary coating machine 1 fall from a height and enter the box 31 of the feeding buffer mechanism 3. At this time, the buffer components 32 at the top and bottom of the inner cavity of the box 31 take effect first. The fertilizer granules first come into contact with the sponge pad 322 on the inner side of the buffer plate 321. The sponge pad 322 absorbs part of the impact force by its own elastic deformation, weakens the impact intensity, and avoids the granules from breaking due to rigid collision.
[0048] When the tilt angle of the buffer plate 321 and the sponge pad 322 needs to be adjusted according to the difference in fertilizer particle size, the servo motor 331 drives the screw 332 at the output end to rotate. Since the screw 332 is threadedly connected to the lifting plate 333 and the lifting plate 333 is sleeved on the limit post 5 on both sides, its rotational freedom is restricted. The rotational motion of the screw 332 is converted into the vertical lifting motion of the lifting plate 333. The racks 334 on both sides of the lifting plate 333 rise and fall synchronously with it. The racks 334 mesh with the gear 324 on the front side of the rotating shaft 323 of the buffer assembly 32, driving the gear 324 and the rotating shaft 323 to rotate. Finally, the buffer plate 321 rotates around the rotating shaft 323 as the center, changing its own tilt angle.
[0049] For large-particle fertilizers, the inclination angle of the buffer plate 321 is reduced by adjusting the plate, which prolongs the contact time and path of the particles on the buffer plate 321. The elasticity of the sponge pad 322 and the support of the buffer plate 321 are used to gradually disperse the strong impact of the large particles and prevent breakage.
[0050] For small-particle fertilizers, the angle of the buffer plate 321 is increased by adjusting it to accelerate the falling speed of the particles and prevent small particles from accumulating and clogging on the surface of the sponge pad 322 due to the angle being too gentle, thus ensuring smooth feeding.
[0051] In summary, by setting up the feeding buffer mechanism 3, the feeding of fertilizer is buffered, preventing fertilizer particles from breaking or pulverizing, which facilitates subsequent processing or application of the fertilizer.
