[0002] Fertilizers can improve soil properties and increase soil fertility. Fertilization is a necessary means to increase crop yields. The quality of fertilizers depends on the quality of the raw materials used in the production process. The uniformity of the particle size of the raw materials is one of the standards for measuring the quality of the raw materials. In order to make the raw materials uniform in particle size, fertilizer raw material crushers often add screen structures.

[0003] The existing publicly available technology, disclosed in CN218359717U, discloses a fertilizer raw material crusher with anti-clogging function, including a screen cylinder. A crushing roller is rotatably connected inside the screen cylinder via a bearing. A collection box is provided outside the screen cylinder. The left side of the crushing roller extends out of the collection box and is rotatably connected to the collection box via a bearing. Through the structure of the screen cylinder, crushing roller, and collection box, clogging is prevented and rapid screening is achieved, resulting in high-efficiency crushing of fertilizer raw materials.

[0004] However, the above-mentioned patent still has certain drawbacks in use: its crushing structure is relatively simple, and the actual crushing effect is very limited. It cannot process fertilizer raw materials more finely, and the discharge port below lacks anti-clogging measures. The crushed raw materials may clog the discharge port, which will affect the subsequent utilization of fertilizer raw materials. The overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a crusher for fertilizer raw materials is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a crusher for fertilizer raw materials according to an embodiment of the present invention includes a crusher 1 and a support leg 14. Several sets of drive shafts 9 are evenly installed on one side surface of the crusher 1. A screen cylinder 3 is fixedly installed at one end of the drive shaft 9. An anti-detachment groove 21 is formed around the outer circumference of the other side of the screen cylinder 3. An anti-detachment ring 20 is abutted around the inside of the anti-detachment groove 21. A retaining ring 19 is welded to the inner surface of the anti-detachment ring 20. A guide port 22 is formed through the inner surface of the retaining ring 19. A guide box 2 is connected to the top of the guide port 22 and is located above the screen cylinder 3 and between each pair of screen cylinders 3. The other end of the retaining ring 19 is fixedly connected to the other side surface of the inside of the crusher 1. A crushing shaft 7 is installed through the middle of the retaining ring 19 and is located in the middle of the inside of the screen cylinder 3. Several sets of inner blades 8 are installed around the surface of the crushing shaft 7. Several sets of outer blades 5 are installed around the outer side of the inner blades 8 on the inner surface of the screen cylinder 3 in an alternating manner.

[0032] In one embodiment, one end of the drive shaft 9 and one end of the crushing shaft 7 both pass through one side of the crusher 1 and are connected to the transmission wheel 11. A transmission chain 10 is connected to the outer periphery of the transmission wheel 11. A first motor 12 is connected to the bottom of the transmission chain 10. A support frame 13 is abutted at the bottom of the first motor 12. The support frame 13 is welded to the surface of the crusher 1. The transmission chain 10 is used to realize the linkage operation between multiple sets of structures.

[0033] In one embodiment, a discharge port 18 is fixedly installed at the middle position of the bottom surface of the crusher 1. A connecting shaft 17 is rotatably connected to the middle position inside the discharge port 18. One end of the connecting shaft 17 passes through one side of the discharge port 18 and is connected to the second motor 15. Several sets of striking rods 16 are installed around the surface of the connecting shaft 17 in an alternating manner. The striking rods 16 are set to strike the falling raw material, thereby preventing the raw material from clumping, preventing the raw material from blocking the discharge port 18, ensuring the smooth falling of the raw material, and improving the feeding efficiency.

[0034] In one embodiment, a feed inlet 6 is fixedly installed on one side of the top surface of the crusher 1. The feed inlet 6 facilitates the addition and use of the fertilizer raw materials to be processed, and facilitates subsequent crushing.

[0035] In one embodiment, support legs 14 are symmetrically installed on both sides of the bottom of the crusher 1. The support legs 14 can fix the entire device, thereby enhancing the overall stability.

[0036] In one embodiment, the inner blade 8 and the outer blade 5 gradually become thinner and their density gradually increases. The change in the inner blade 8 and the outer blade 5 is to improve the crushing effect inside different screen cylinders 3, improve the overall crushing quality, and facilitate better use.

[0037] In one embodiment, a number of sets of screens 4 are arranged around the surface of the screen cylinder 3, and the size of the holes on the surface of the screens 4 gradually decreases. The change in the size of the screens 4 is to allow the raw materials to be crushed a second or even multiple times, thereby improving the fineness of the crushed raw materials and making them easier to use later.

[0038] In one embodiment, the anti-detachment ring 20 has the same size as the anti-detachment groove 21. The same size ensures that the anti-detachment ring 20 will not detach from the anti-detachment groove 21, thereby ensuring that the screen cylinder 3 can rotate inside the retaining ring 19 and can rotate under the drive of the first motor 12.

[0039] Working Principle: In actual use, the fertilizer raw materials to be crushed can be added to the crusher 1 through the feed inlet 6. The falling fertilizer raw materials will then enter the feed inlet 22 along the feed box 2 and be discharged into the screen cylinder 3 along the retaining ring 19. At this time, the first motors 12 on both sides run simultaneously in opposite directions, so that the rotation direction of the screen cylinder 3 is opposite to the rotation direction of the crushing shaft 7. The inner blades 8 and outer blades 5, which rotate in opposite directions, will miss each other, allowing the fertilizer raw materials to be cut and crushed multiple times. The surface of the screen cylinder 3 is equipped with a screen mesh 4. The crushed material smaller than the size of the screen mesh 4 will be discharged outwards. The discharged material will then... The material guide box 2 re-enters the lower screen cylinder 3 and repeats the above operation, and finally crushes and discharges from the bottom screen cylinder 3. Since the raw material is processed by multiple screen cylinders 3, its crushing effect can be greatly improved, and the crushed raw material can be finer. Then the crushed raw material will be discharged through the discharge port 18. At this time, the operation of the second motor 15 can drive the connecting shaft 17 to rotate. The striking rod 16 on its surface can strike the falling raw material, thereby causing the surface raw material to re-clump, thus preventing the phenomenon of clogging the discharge port 18 when falling, ensuring the actual discharge efficiency. The device as a whole has the advantages of good crushing effect, anti-clogging discharge, and multiple crushing and screening.
