DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Embodiment 1:

[0034] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a mixing assembly 200 of a fertilizer processing device. The mixing assembly 200 is installed on a frame 100. Through this embodiment, effective mixing of fertilizers is achieved, and the mixing effect and practicality of the equipment are improved through flexible angle adjustment and efficient stirring design.

[0035] Specifically, the mixing assembly 200 includes a mounting plate 210, a first working part 220 and a second working part 230. The mounting plate 210 is rotatably mounted on the frame 100 for carrying the first working part 220 and the second working part 230. The second working part 230 is fixedly mounted on the mounting plate 210, and the first working part 220 is rotatably mounted on the second working part 230. A first cylinder 240 is rotatably mounted in the frame 100, and an output end of the first cylinder 240 is rotatably connected to the mounting plate 210, so that the mounting plate 210 can rotate around a certain axis, and the overall angle of the mixing assembly 200 can be adjusted to meet different processing requirements, such as changing the mixing method of materials or improving mixing efficiency.

[0036] Reference Figure 1 and Figure 2 and Figure 3 Preferably, the first working part 220 includes a ball disc 221, a positioning frame 222 and a first motor 223. The positioning frame 222 is fixedly mounted on the mounting plate 210 and has an open groove 201. The ball disc 221 is rotatably mounted on the positioning frame 222. The outer edge surface of the ball disc 221 has teeth 202. The first motor 223 is fixedly mounted on the mounting plate 210. The output end of the first motor 223 is fixedly mounted with a gear 224 meshing with the teeth 202 for driving the ball disc 221 to rotate.

[0037] Reference Figure 1 In order to ensure that the material does not adhere to the inner wall of the ball tray 221 during the mixing process, preferably, a first telescopic rod 225 is fixedly installed on the second working part 230, and a scraper 226 is fixedly installed on the first telescopic rod 225. The scraper 226 is located in the cavity of the ball tray 221 and can scrape off the material on the inner wall of the ball tray 221 as the first telescopic rod 225 telescopes.

[0038] The first cylinder 240 is rotatably connected to the mounting plate 210 through its output end, so that the mounting plate 210 can be rotated around a certain axis. By adjusting the angle of the mounting plate 210, different processing requirements can be met, such as changing the material mixing method or improving the mixing efficiency. The first motor 223 engages with the teeth 202 on the outer edge surface of the ball disc 221 through the gear 224 to drive the ball disc 221 to rotate. When the ball disc 221 rotates, the fertilizer placed in the ball disc 221 can be rolled, mixed and formed by the action of centrifugal force and gravity, and the granulation parameters can be adjusted according to the fertilizer type and the required particle size, which greatly improves the uniformity of the fertilizer particles, thereby improving the overall quality and use effect of the fertilizer.

[0039] Reference Figure 2 and Figure 3Preferably, the second working part 230 includes a cover shell 231, a partition 232, a rotor plate 233 and a second motor 234, one side of the cover shell 231 is fixed to the mounting plate 210, and the other side of the cover shell 231 is rotatably connected to the ball disk 221, the partition 232 is installed in the cover shell 231, and the interior of the cover shell 231 is divided into two different spaces, the rotor plate 233 is rotatably installed in the space close to one side of the mounting plate 210, the rotor plate 233 has a ball portion 203 at the center, and the ball portion 203 extends a connecting rod 204 to one side of the mounting plate 210, a U-shaped frame 211 is fixedly installed on the mounting plate 210, the second motor 234 is fixedly installed on the U-shaped frame 211, and a connecting rod 205 is connected between the second motor 234 and the connecting rod 204.

[0040] A ball groove matched with the ball part 203 is provided on the partition plate 232, so that the ball part 203 is rotatably installed in the ball groove, thereby completing the installation of the rotor plate 233 and the partition plate 232.

[0041] It is worth noting that the connecting rod 204 is collinear with the center of the rotor plate 233 , and the output end of the second motor 234 is collinear with the center of the ball disk 221 .

[0042] Reference Figure 1 and Figure 2 and Figure 3 Furthermore, a water outlet 260 is fixedly mounted on the cover shell 231, a first piston member 250 is fixedly mounted on the mounting plate 210, a water pipe 255 is connected between one end of the first piston member 250 and the water outlet 260, and the other end of the first piston member 250 is connected to an external water source through a first hose 251; wherein, a one-way valve is installed in both the water outlet 260 and the first hose 251 to prevent water from flowing back and ensure unidirectional flow of water.

[0043] A second piston member 270 is fixedly mounted on the mounting plate 210 , and an air pipe 271 is connected between one end of the second piston member 270 and the blanking assembly 300 .

[0044] In actual operation, the second motor 234 drives the connecting rod 204 through the connecting rod 205 to drive the rotor plate 233 to rotate in the cover shell 231. The rotor plate 233 generates a swinging periodic shaking on the partition 232 through its own ball portion 203 and intermittently squeezes the first piston member 250 and the second piston member 270. One end of the first piston member 250 is connected to the water outlet 260, and the other end is connected to an external water source through the first hose 251. The reciprocating motion of the piston controls the flow of water in and out to form a water supply system, which is mainly used to inject an appropriate amount of water into the mixing space to help the materials mix better and make the particle surface smooth and the size consistent; the second piston member 270 and the feeding assembly 300 are used to transmit compressed air to make the feeding assembly 300 vibrate to achieve material screening and remove particles that do not meet the size requirements. For the unqualified particles screened out, they can be re-entered into the granulation or mixing stage through the recovery system to improve the utilization rate of raw materials.

[0045] Better, refer to Figure 5 The first piston member 250 includes a sealing cylinder 252, a sealing plate 253 and a push rod 254. The water outlet 260 and the first hose 251 are both installed on the sealing cylinder 252. The push rod 254 is rotatably connected to the rotor plate 233. When the rotor plate 233 generates a swinging periodic shaking on the partition 232 through its own ball portion 203 and intermittently squeezes or pulls the push rod 254, when the push rod 254 is squeezed, the water in the sealing cylinder 252 is squeezed into the water outlet 260 and sprayed on the fertilizer, ensuring that the water inside the particles is evenly distributed. When the push rod 254 is pulled, a negative pressure is generated inside the sealing cylinder 252 to allow the water to enter the sealing cylinder 252 through the first hose 251 for replenishment, which is convenient for secondary spraying.

[0046] The structure and principle of the second piston member 270 are the same as those of the first piston member 250 , and are not described in detail herein.

[0047] Better, refer to Figure 4 The water outlet 260 includes a hollow rod 261 , a distribution head 262 and an atomizing nozzle 263 , and a one-way valve is installed in the hollow rod 261 .

[0048] Embodiment 2:

[0049] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides a feeding component 300 of a fertilizer processing equipment, which realizes the automation and efficiency of the fertilizer particle screening process, and improves the performance and practicality of the fertilizer processing equipment.

[0050] Reference Figure 6Specifically, the unloading assembly 300 includes a screening plate 310 and a guide plate 320. The end of the screening plate 310 away from the ball disc 221 is rotatably connected to the frame 100 by a first connecting arm 330. The other end of the screening plate 310 is slidably connected to the frame 100 by a second connecting arm 340. An airbag 350 is fixedly mounted on the second connecting arm 340, and the airbag 350 is connected to the air pipe 271.

[0051] The airbag 350 is connected to the air pipe 271, and the air pressure in the airbag 350 is adjusted by the second piston member 270. When the gas inside the airbag 350 is sufficient, an upward thrust is applied to the second connecting arm 340, so that one end of the screen plate 310 is raised and the other end is lowered accordingly. When the gas inside the airbag 350 is deflated, the inclination angle of the screen plate 310 can be changed in this way, thereby affecting the movement trajectory of the fertilizer particles thereon.

[0052] When the mixed fertilizer particles are discharged from the ball tray 221, they fall on the screen plate 310. At this time, by adjusting the air pressure in the airbag 350, the inclination angle of the screen plate 310 can be controlled to achieve the screening of the fertilizer particles. Smaller particles may fall directly through the gap of the screen plate 310, while larger particles will slide along the surface of the screen plate 310 and the guide plate 320, and finally flow out of the device along the preset path.

[0053] Embodiment three:

[0054] Reference Figure 3 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: this embodiment provides a knocking component to achieve uniform mixing effect.

[0055] Specifically, a slide column 235 is installed on the partition plate 232 through an elastic member. Optionally, the elastic member is a spring. When the slide column 235 is squeezed by the rotor plate 233 , the slide column 235 abuts against the ball disc 221 .

[0056] The slide column 235 is connected to the partition plate 232 through a spring. When the rotor plate 233 approaches the slide column 235 during the mixing process, the slide column 235 will extend toward the ball disc 221 under the action of the spring and contact the ball disc 221 to produce a knocking effect, thereby further reducing the accumulation of fertilizer on the ball disc 221. When the rotor plate 233 rotates, it will continuously squeeze the slide column 235. Then, as the rotor plate 233 continues to rotate, the slide column 235 will separate from the ball disc 221 due to the elastic force of the spring and return to the initial position, thereby ensuring that the fertilizer is evenly distributed throughout the mixing process.

[0057] A fertilizer processing technology, wherein fertilizer is put into a ball tray 221, a first cylinder 240 is connected to a mounting plate 210 through its output end, so that the mounting plate 210 can be rotated around a certain axis, and the angle of the mounting plate 210 can be adjusted to meet different processing requirements, a first motor 223 is meshed with teeth 202 on the outer edge of the ball tray 221 through a gear 224, and drives the ball tray 221 to rotate, and when the ball tray 221 rotates, the fertilizer put into the ball tray 221 can be moved by centrifugal force and gravity The fertilizer is rolled, mixed and formed by the action of the second motor 234. The granulation parameters can be adjusted according to the fertilizer type and the required particle size, which greatly improves the uniformity of the fertilizer particles. The second motor 234 drives the connecting rod 204 to drive the rotor plate 233 to rotate in the cover 231 through the connecting rod 205. The rotor plate 233 generates a swinging periodic shaking on the partition 232 through its own ball portion 203. The sliding column 235 will extend toward the ball disc 221 under the action of the spring and contact the ball disc 221 to generate a knocking effect. To further reduce the accumulation of fertilizer on the ball disc 221, at the same time, the rotor plate 233 intermittently squeezes the first piston member 250 and the second piston member 270. One end of the first piston member 250 is connected to the water outlet 260, and the other end is connected to the external water source through the first hose 251. The reciprocating motion of the piston controls the flow of water in and out to form a water supply system, which is mainly used to inject an appropriate amount of water into the mixing space to help the materials to be better mixed and make the particle surface smooth and uniform in size; the second piston member 270 and the feeding assembly 300 are used to transmit compressed air to the airbag 350. When the air in the airbag 350 is sufficient, an upward thrust is applied to the second connecting arm 340, so that one end of the screen plate 310 is raised and the other end is correspondingly lowered. When the gas in the airbag 350 is deflated, the inclination angle of the screen plate 310 can be changed in this way, thereby affecting the movement trajectory of the fertilizer particles on it. When the mixed fertilizer particles are discharged from the ball disc 221, they will fall on the screen plate 310. At this time, by adjusting the air pressure in the airbag 350, the inclination angle of the screen plate 310 can be controlled, thereby achieving screening of the fertilizer particles. Smaller particles may fall directly through the gaps in the screen plate 310, while larger particles will slide along the surface of the screen plate 310 and the guide plate 320, and finally flow out of the device along a preset path.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
