[0020] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] The utility model provides a fertilizer raw material crusher, as shown in the figure, the fertilizer raw material crusher comprises a chassis 1, a crushing mechanism and a cleaning mechanism 3, wherein the upper end and the lower end of the chassis 1 are respectively provided with a feed port and a discharge port, the crushing mechanism is arranged in the chassis 1, the crushing mechanism comprises two parallel and spaced crushing rollers, the crushing rollers 2 of the crushing mechanism are driven to work by an externally arranged driving device, the two crushing rollers 2 rotate relative to each other to generate shear force and extrusion, and gradually crush the bulk fertilizer raw materials into required fine particles, the crushing mechanism and the driving device are existing devices, the present application is not to improve them, and their specific structures are no longer described.

[0023] The cleaning mechanism 3 includes a scraper 31, a collection box 32 and a mounting frame. The collection box 32 is arranged outside the chassis 1 and communicated with the inside of the chassis 1. The mounting frame is installed in the chassis 1. The scraper 31 is arranged in cooperation with the mounting frame so that the scraper 31 is arranged obliquely in the chassis 1. One end of the scraper 31 can abut against the outer peripheral wall of the crushing roller 2, and the other end of the scraper 31 passes through the chassis 1 and extends into the collection box 32. The end of the scraper 31 facing the stirring roller is higher than the end of the scraper 31 facing the collection box 32. Definition: The feed port and the discharge port of the chassis 1 are respectively arranged in the up and down directions, the two crushing rollers 2 are respectively in the left and right directions, and the two ends of the crushing rollers 2 are respectively in the front and back directions. Two cleaning mechanisms 3 are provided, and the two cleaning mechanisms 3 are respectively arranged at the lower relative far sides of the two crushing rollers 2 (i.e., located at the lower left and lower right in the chassis 1).

[0024] As an optional embodiment, the mounting frame includes a main rod 33 fixed in the chassis 1, a support rod 34 mounted on the main rod 33, the support rod 34 is perpendicular to the main rod 33, and the support rod 34 can slide along the main rod 33, the scraper 31 is tilted on the support rod 34, and an electric push rod 35 with a movable end connected to the support rod 34 is fixed in the chassis 1. The extension and retraction direction of the electric push rod 35 is parallel to the length direction of the main rod 33. The electric push rod 35 works to drive the scraper 31 to move closer to or away from the crushing roller 2. The device can adjust the relative position of the scraper 31 and the crushing roller 2 as needed to remove the compaction, facilitate the compaction treatment of raw materials with different hardness and viscosity, and avoid excessive wear or scratching of the crushing roller 2.

[0025] Since the compacted materials cleaned are easily discharged from the discharge port, the compacted materials are mixed with the crushed materials, resulting in inconsistent coarseness and fineness. To solve this problem, the cleaning mechanism 3 also includes a guide plate 38 fixed on the mounting frame. The guide plate 38 is located below the scraper 31, and the guide plate 38 extends obliquely toward the crushing roller 2. One end of the guide plate 38 passes through the chassis 1 and extends into the collecting box 32, and the other end of the guide plate 38 extends to the outside and below of the contact point between the scraper 31 and the crushing roller. The height of the end of the guide plate 38 extending into the collecting box 32 is lower than the height of the end of the guide plate 38 close to the crushing roller.

[0026] Further, as required, the outer peripheral wall of the crushing roller is provided with convex rings spaced apart in the axial direction thereof, and the two crushing rollers 2 are staggered so that the convex ring of one crushing roller 2 can be inserted between the adjacent convex rings of the other crushing roller 2, and the shape of the end of the scraper 31 close to the crushing roller 2 matches the shape of the crushing roller 2, so that the scraper 31 can be inserted between any adjacent convex rings of the crushing roller 2. Alternatively, the outer surface of the crushing roller is set as a smooth surface, and the two crushing rollers are spaced apart and a crushing channel is formed between them.

[0027] In the above description, the bottom of the collecting box 32 is provided with a discharge port.

[0028] Embodiment 2

[0029] The difference between the second embodiment and the first embodiment lies in the setting of the mounting frame. In this embodiment, the mounting frame includes a main rod 33 fixed in the chassis 1, a support rod 34 vertically arranged on the main rod 33, and the scraper 31 is hinged to the support rod 34 so that the scraper 31 can rotate relative to the straight rod. The scraper 31 is inclined and one end of the scraper 31 is against the crushing roller 2. A long hole is opened on the side of the scraper 31 away from the crushing roller. The bolt 36 is connected to the chassis 1 after passing through the long hole. A compression spring 37 is arranged between the cap top of the bolt 36 and the scraper 31. The scraper 31 is against the crushing roller. The cap top of the bolt 36 is located on the lower side of the scraper 31. The height of the cap top of the bolt 36 is lower than the abutment height of the scraper 31 and the crushing roller 2. The scraper 31 can change its angle and avoid it after colliding with the hard material on the crushing roller, and the compression spring 37 can provide continuous pressure to ensure that the scraper 31 and the crushing roller maintain stable contact.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
