[0019] In order to make the technical personnel of the technical field better understand the present utility model scheme, the technical scheme in the present utility model embodiment will be clearly and completely described below in conjunction with the drawings in the present utility model embodiment. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by the technical personnel in the technical field belonging to the present utility model. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a rock sugar crusher comprises a crushing box 1 with a feed hopper at the top and a discharge port at the bottom, and two pairs of crushing rollers arranged in parallel and correspondingly in the crushing box 1. Both pairs of crushing rollers are rotatably connected to the crushing box 1. Each pair of crushing rollers comprises two roller shafts 2 arranged horizontally at intervals and a plurality of crushing teeth 3 arranged alternately on the two roller shafts 2. Specifically, the crushing teeth 3 on the same row are arranged at intervals along the axial direction, and the crushing teeth 3 in two adjacent rows are arranged alternately. A driving mechanism 5 for driving the two pairs of crushing rollers to rotate is provided outside the crushing box 1. The crushing teeth 3 on the corresponding roller shafts 2 are also arranged alternately. Multiple square steels 4 are arranged on each roller shaft 2 along the circumference of the shaft, and the square steels 4 are all extended along the axial direction.

[0022] like Figure 4 As shown, the crushing tooth 3 is composed of a cylindrical section 31 at the root and a conical section 32 at the tail. The height of the cylindrical section 31 of the crushing tooth 3 is 2-2.5 times the height of the conical section 32. The cylindrical section 31 generates a hammering impact force to crush the rock sugar, and the crushing process is not easy to destroy the crystal structure of the rock sugar, and the crushing effect is better.

[0023] In this embodiment, a square steel 4 is arranged every two rows of crushing teeth 3, so that the square steels 4 on the two corresponding crushing rollers are also staggered. The height of the square steel 4 on the same crushing roller is equal to the height of the cylindrical section 31 of the crushing teeth 3 thereon. The length of the square steel 4 is equal to the length of the roller shaft 2. Since the square steel 4 cooperates with the adjacent crushing teeth 3 to generate an extrusion force to crush the rock sugar, the crushed rock sugar particles are more uniform.

[0024] The ratio of the height of the crushing teeth 3 on the same crushing roller to the diameter of the roller shaft 2 is 0.2-0.4, which is beneficial to improve the crushing capacity of the material.

[0025] The diameter of the roller shaft 2 at the upper part is 1.5-2 times the diameter of the roller shaft 2 at the lower part. The setting density of the crushing teeth 3 at the upper part is 2-3 times the setting density of the crushing teeth 3 at the lower part, and the height of the crushing teeth 3 at the upper part is 2-3 times the height of the crushing teeth 3 at the lower part. By setting the crushing teeth 3 on the upper and lower pairs of crushing rollers to different thicknesses and sizes, coarse upper and fine lower crushing is achieved.

[0026] The linear speed of the upper roller 2 is greater than that of the lower roller 2. In this embodiment, the upper and lower pairs of crushing rollers are driven by one motor, and the difference in the linear speed of the upper and lower pairs of rollers 2 can be achieved by using different transmission gears.

[0027] The crusher of the utility model utilizes the crushing teeth 3 staggered on the crushing roller and the square steel 4 on the crushing roller to cooperate in crushing rock sugar, thereby improving the uniformity of crushing rock sugar particles.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
