Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a large-piece material crusher. Background Technique

[0002] Fertilizers refer to substances that provide one or more essential nutrient elements for plants, improve soil properties, and enhance soil fertility levels, and are one of the material bases for agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers for macronutrients, fertilizers for micronutrients, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. When processing fertilizers, it is necessary to use a large-piece material crusher for auxiliary treatment to obtain fine fertilizer raw materials and finished products.

[0003] In view of this, Chinese Patent No. CN217016797U proposes a large-piece material crusher. By setting the first transmission gear, crushing rollers, and crushing bumps, it is avoided that the crusher is difficult to completely crush the materials due to different falling directions of the materials during the process of processing the materials. At the same time, since the two sets of reversely rotating crushing rollers are in a state of rotating towards each other, the crusher has the effect of pulling the materials, avoiding the situation of rotation or stagnation in the material feeding shell, so that the crusher can meet the needs of industrial large-scale material crushing. However, in the above patent, when the large-piece material crusher is in use, it is prone to the hidden problem of material splashing during crushing, which not only causes environmental pollution and material waste, but also is more likely to cause problems with the health and safety of workers, reducing the practicability of the large-piece material crusher. Therefore, a large-piece material crusher is needed. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a large-piece material crusher to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model proposes a large-piece material crusher, including a crushing protection frame, which is used for protecting large-piece materials during fertilizer processing. An anti-splashing protection mechanism is fixedly arranged on the inner wall of the crushing protection frame, and an anti-dust mechanism is fixedly arranged at the bottom end of the crushing protection frame;

[0006] The anti-splashing protection mechanism includes a rotating frame, one end of the rotating frame is fixedly provided with a protection plate, a protection guiding groove is fixedly arranged on the inner wall of the crushing protection frame, the outer wall of the protection plate is in contact with one side of the inner wall of the protection guiding groove, one side of the crushing protection frame is fixedly provided with a first motor, the output end of the first motor passes through the crushing protection frame and is fixedly connected with one end of the rotating frame, and one end of the top of the crushing protection frame is fixedly provided with a feeding frame.
