Description

Technical Field

[0001] This application relates to the field of fertilizer crushing, and more specifically, to a material crusher for blended fertilizers. Background Technology

[0002] Blended fertilizers (also known as BB fertilizers) are granular fertilizers made by physically and mechanically mixing unit fertilizers (such as urea, ammonium phosphate, etc.) or compound fertilizers. The production process only requires physical mixing and does not require complex chemical reaction equipment. It has low cost and high flexibility. The raw materials are mostly granular fertilizers with similar particle size to ensure uniform mixing.

[0003] In the production of blended fertilizers, it is necessary to crush the agglomerated raw materials. The raw materials are crushed by a crushing device and then mixed before granulation. Existing fertilizer production raw material crushing devices crush the added raw materials. The crushed materials are screened before being discharged to obtain crushed materials that meet the standards. However, the screen of the screening mechanism is not stationary, which can easily cause the screen to clog during screening.

[0004] Chinese patent application number CN202321915076.8 discloses a crushing device for fertilizer production, including a crushing box, a set of crushing blades arranged inside the crushing box, a feed hopper arranged at the top of the crushing box, a discharge hopper arranged at the bottom of the crushing box, and a screening structure. The screening structure is arranged inside the crushing box. The screening structure is located below the set of crushing blades. When the screening part comes into contact with the crushed material, it is impacted and can shake relative to the connecting part of the screening structure, so that the screening part of the screening structure is less likely to be blocked due to shaking.

[0005] The above-mentioned scheme has the following shortcomings: the fertilizer is discharged after being crushed and screened by the crushing blade group. The crushing method is singular. If there are lumps of fertilizer raw materials, it is not easy to perform preliminary crushing, thereby reducing the crushing efficiency, reducing the crushing effect of fertilizer, affecting subsequent processing and use, and reducing the practicality of the device.

[0028] Please see Figure 1 This application provides a material crusher for blending fertilizers, including a feeding structure 10 and a crushing structure 20.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The feeding structure 10 includes a support frame 110, a feeding hopper 120, a fixed box 130, and a crushing box 140. The fixed box 130 is fixedly connected to the support frame 110, the feeding hopper 120 is connected to the fixed box 130, and the crushing box 140 is connected to the fixed box 130.

[0030] In a specific configuration, a reset assembly 150 is provided inside the fixed box 130. The reset assembly 150 includes two support plates 151 and springs 152. Two support plates 151 are arranged opposite each other on the inner wall of the fixed box 130. Several springs 152 are evenly arranged on one side of the support plates 151. The springs 152 are fixedly connected to the inclined plate 210. The arrangement of the two support plates 151 and springs 152 facilitates the reset of the inclined plate 210, ensuring the stability of the intermittent contact action between the pressure plate 220 and the eccentric wheel 230.

[0031] In the specific setup, a baffle 160 is slidably connected to one side of the feeding hopper 120. A groove is provided on one side of the baffle 160. The baffle 160 can effectively prevent dust from overflowing during crushing, thus providing protection.

[0032] In the specific setup, the bottom inner wall of the crushing box 140 is inclined, which allows for convenient and rapid discharge of crushed fertilizer.

[0033] In a specific configuration, a discharge port is provided through the bottom of the crushing box 140, which facilitates material discharge.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The crushing structure 20 includes an inclined plate 210, a pressure plate 220, an eccentric wheel 230, a drive assembly 240, and two crushing rollers 250. The inclined plate 210 is rotatably connected to the fixed box 130, the pressure plate 220 is fixedly connected to the inclined plate 210, the eccentric wheel 230 is connected to the drive assembly 240, and the eccentric wheel 230 is intermittently in contact with the inclined plate 210. The drive assembly 240 is set inside the crushing box 140, and both crushing rollers 250 are connected to the drive assembly 240.

[0035] In a specific configuration, the drive assembly 240 includes an L-shaped mounting plate 241, a motor 242, a first rotating shaft 243, a second rotating shaft 244, two gears 245, a third rotating shaft 246, two pulleys 247, and a belt 248. The L-shaped mounting plate 241 is fixedly connected to one side of the support frame 110. The motor 242 is mounted on one side of the L-shaped mounting plate 241. The first rotating shaft 243 is connected to the output end of the motor 242. Both the first rotating shaft 243 and the second rotating shaft 244 are rotatably connected to the crushing box 140. The two gears 245 are fixedly connected to the outer rings of the first rotating shaft 243 and the second rotating shaft 244, respectively, and the two gears 245 mesh with each other. The two crushing rollers 250 are respectively connected to the first rotating shaft 243 and the second rotating shaft 244. The outer ring of the rotating shaft 244 is fixedly connected, and the outer rings of the second rotating shaft 244 and the third rotating shaft 246 are both fixedly connected to pulleys 247. The two pulleys 247 are connected by a belt 248. The outer ring of the third rotating shaft 246 is fixedly connected to several eccentric wheels 230. The arrangement of the L-shaped mounting plate 241, motor 242, first rotating shaft 243, second rotating shaft 244, two gears 245, third rotating shaft 246, two pulleys 247 and belt 248 can easily drive the eccentric wheels 230 to rotate, so that the inclined plate 210 drives the pressure plate 220 to initially crush the clumped fertilizer. At the same time, it can easily drive the two crushing rollers 250 to perform fine crushing, thereby improving the crushing efficiency and the crushing effect.

[0036] In a specific configuration, a pressing port 170 is formed between the pressing plate 220 and the inner wall of the fixed box 130, wherein the pressing port 170 formed between the pressing plate 220 and the inner wall of the fixed box 130 is capable of pressing materials.

[0037] The working principle of this fertilizer blending material crusher is as follows: When using the fertilizer blending material crusher, the fertilizer raw material enters the fixed box 130 through the feeding hopper 120. After the baffle 160 is closed, the motor 242 drives the first rotating shaft 243 to rotate, causing the two meshing gears 245 and the crushing roller 250 to rotate relative to each other. At the same time, the eccentric wheel 230 on the third rotating shaft 246 is rotated through the pulley 247 and belt 248. When the eccentric wheel 230 periodically squeezes the inclined plate 210, the inclined plate 210 rotates around the fixed box 130 and drives the pressure plate 220 to move. With the help of the spring 152 of the reset component 150, the reciprocating motion is achieved, which initially crushes the agglomerated fertilizer at the pressing port 170. Then the material enters the crushing box 140 and is finely crushed by the two counter-rotating crushing rollers 250. Finally, the crushed material is quickly discharged from the discharge port along the inclined bottom of the crushing box 140. This can achieve a two-stage crushing synergy, improving the crushing efficiency and effect.

[0038] It should be noted that the specific models and specifications of the motor 242 and the crushing roller 250 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and principle of motor 242 are clear to those skilled in the art and will not be described in detail here.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
