[0001] This utility model relates to the field of granular fertilizer production technology, specifically a hammer crusher for granular fertilizer production. Background Technology

[0002] Granular fertilizer combines the advantages of traditional chemical fertilizers and water-soluble fertilizers, featuring long-lasting effects and convenient application, making it popular among growers. When producing granular fertilizer, a crusher is needed to crush the raw materials to facilitate the mixing of various components.

[0003] Currently, when a hammer roller crusher crushes raw materials, the gaps between the hammers cause the raw materials to fall between them as they enter the crusher. This prevents the hammers from crushing the raw materials quickly, leading to material accumulation inside the crusher. This affects the intake and crushing of subsequent raw materials, reducing processing efficiency. Therefore, we have proposed a hammer roller crusher for granular fertilizer production to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hammer roller crusher for granular fertilizer production, in order to solve the problem mentioned in the background art that, when hammer roller crushers on the market are crushing raw materials, the gaps between the crushing hammers cause the raw materials to fall between the crushing hammers when entering the crusher, which prevents the crushing hammers from crushing the raw materials quickly. The raw materials accumulate in the crusher, affecting the subsequent intake and crushing of raw materials and reducing processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hammer roller crusher for producing granular fertilizer, including a crusher shell, a feed inlet at the upper end of the crusher shell, a discharge inlet at the lower end of the crusher shell, a support leg connected to the lower part of the crusher shell, and a filter screen opening on the lower side of the crusher shell.

[0006] A motor is installed at the rear end of the crusher housing. A rotating rod is connected to the output end of the motor. A turntable is connected to the outer side of the rotating rod. A crushing hammer is connected to the outer edge of the turntable by fixing bolts.

[0007] The turntable has a storage slot inside, and a crushing disc is set inside the storage slot. A moving rod is connected to the crushing disc, and one end of the moving rod is elastically connected to the turntable by a spring.

[0008] The inner wall of the crusher casing is connected with protrusions.

[0009] Preferably, the bottom of the crusher shell is arc-shaped, and filter mesh holes are evenly distributed on the bottom of the crusher shell.

[0010] Preferably, the turntables are evenly distributed on the rotating rod, and the thickness of the outer edge of the turntable is less than the thickness of the central area of ​​the turntable.

[0013] Preferably, the crushing discs are interconnected by a movable rod, which slides through the turntable. The contact points between the movable rod and the protrusion are smooth, and the protrusion has a trapezoidal structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The hammer crusher for producing granular fertilizer uses a turntable to control the rotation of the crushing hammer for crushing. The protrusion pushes the moving rod to control the movement of the crushing disc. The crushing disc and the turntable squeeze and crush the raw material entering between them, so as to achieve rapid crushing of the raw material and avoid it from accumulating in the crusher shell and causing jamming.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a hammer roller crusher for producing granular fertilizer, including a crusher shell 1, a feed inlet 2 at the upper end of the crusher shell 1, a discharge inlet 3 at the lower end of the crusher shell 1, a support leg 14 connected to the lower part of the crusher shell 1, and a filter screen 4 on the lower side of the crusher shell 1.

[0025] Furthermore, the bottom of the crusher shell 1 is arc-shaped, and the bottom of the crusher shell 1 is evenly distributed with filter mesh holes 4, which can concentrate the crushed material to the filter mesh holes 4, so that it can pass through the filter mesh holes 4 for discharge.

[0026] A motor 5 is installed at the rear end of the crusher housing 1. A rotating rod 7 is connected to the output end of the motor 5. A turntable 8 is connected to the outer side of the rotating rod 7. A crushing hammer 9 is connected to the outer edge of the turntable 8 by fixing bolts 6.

[0027] Furthermore, the turntables 8 are evenly distributed on the rotating rod 7, and the thickness of the outer edge of the turntable 8 is less than the thickness of the central area of ​​the turntable 8, which makes it easier to fix the breaker hammer 9 to the outer edge of the turntable 8, thereby realizing the installation and fixation of the breaker hammer 9.

[0028] Furthermore, the end of the breaker 9 near the turntable 8 has an "n" shaped structure, and the breaker 9 and the turntable 8 are interlocked, which facilitates the assembly of the breaker 9.

[0029] The turntable 8 has a storage groove 12 inside, and a crushing disc 10 is installed inside the storage groove 12. A moving rod 11 is connected to the crushing disc 10, and one end of the moving rod 11 is elastically connected to the turntable 8 through a spring 15. A protrusion 13 is connected to the inner wall of the crusher housing 1.

[0030] Furthermore, the opposing surfaces of the crushing disc 10 and the turntable 8 are both rough, and the crushing disc 10 is slidably connected to the rotating rod 7, so that when the crushing disc 10 moves, the material can be crushed by using the crushing disc 10 and the turntable 8 with a shortened distance.

[0031] Furthermore, the crushing discs 10 are interconnected by moving rods 11. The moving rods 11 slide through the turntable 8. The contact points between the moving rods 11 and the protrusions 13 are smooth. The protrusions 13 have a trapezoidal structure. The moving rods 11 are moved by the protrusions 13, thereby controlling the movement of the crushing discs 10.

[0032] Specifically, when using this granular fertilizer production hammer crusher, the raw materials for granular fertilizer production are fed into the crusher housing 1 through the feed inlet 2. The motor 5 is connected to the power supply, and the control rod 7 connected to the output end is rotated counterclockwise, thereby controlling the rotation of the turntable 8 installed on the outside. The turntable 8 drives the crushing hammer 9 installed on the outside to rotate counterclockwise. The crushing hammer 9 is used to crush the raw materials for granular fertilizer production. The crushed raw materials pass through the filter screen 4 and are then discharged from the discharge port 3. The uncrushed raw materials continue to be crushed in the crusher housing 1 using the crushing hammer 9.

[0033] When the turntable 8 rotates, the crushing disc 10 housed inside it rotates synchronously, and the moving rod 11 connected to the crushing disc 10 rotates synchronously. When the position of the moving rod 11 gradually contacts the position of the protrusion 13, the protrusion 13 can push the moving rod 11 to move. The moving rod 11 pushes the crushing disc 10 to move closer to the adjacent position of the turntable 8, shortening the distance between the two. At the same time, the crushing disc 10 compresses and stores the spring 15, crushing the raw material entering between the crusher hammer 9 and the turntable 8, realizing the rapid crushing of the raw material and avoiding its accumulation in the crusher shell 1, which would cause jamming. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
