Specific embodiments
[0012] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and do not intend to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0013] Here, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.
[0014] Refer to as Figure 1 , Figure 2 shown, the following technical solutions are adopted in this specific embodiment: It includes a fixed bottom plate 1, a reinforcing rib 2, an impact crushing groove 3, a crushing cavity 4, an impact breaking and throwing disc 5, a sand falling groove 6, a feeding port 7, a partition steel plate 8, a segmented impact cavity 9, and a material guiding slope 10; the upper end of the fixed bottom plate 1 is connected with an impact crushing groove 3 through a circle of reinforcing ribs 2, a circle of crushing cavities 4 is arranged on the inner and outer sides of the impact crushing groove 3, an impact breaking and throwing disc 5 is arranged in the middle of the crushing cavity 4, the impact breaking and throwing disc 5 is connected with a driving device at the bottom, and a sand falling groove 6 is reserved between the impact breaking and throwing disc 5 and the crushing cavity 4; it is characterized in that: several segmented impact cavities 9 are separated by a partition steel plate 8 inside the crushing cavity 4, and a material guiding slope 10 is obliquely arranged inside the segmented impact cavity 9.
[0015] Among them, the material guiding slope 10 is a concave-convex triangular groove structure, and the material guiding slope 10 keeps a slope of 30-45 degrees with the horizontal plane; the outer contour of the partition steel plate 8 is a structure in the shape of a letter "R".
[0016] Working principle of this specific embodiment: The thickness of the steel plate 8 is 5 cm; the partition steel plate 8 is a very effective impact and fragmentation receiving plate. After the stone impacts on the partition steel plate 8, it is restricted within the small circulation range in the segmented impact chamber 9, which can reduce the loss of the energy of mutual impact caused by the long-distance flight of the stone in the chamber. At the same time, within a small range, the stones have more opportunities to collide and squeeze with each other, forming higher production capacity and better particle shape; while the stones that are not completely crushed slide down along the material guiding slope 10 to the upper end of the sand discharge chute 6 and are blocked and retained. The retained stones and the stones thrown out by the impact crusher throwing disc 5 are secondarily impacted to meet the crushing requirements.
[0017] Beneficial effects of this specific embodiment: 1. The segmented cavity structure changes the traditional sand-making cavity into a small-range segmented cavity, enabling the stones thrown out by the throwing disc to form a swirling flow within a small range, with higher crushing efficiency.
[0018] 2. The strong crushing structure: Due to the partition plate with a thickness of about 5 cm in the cavity, which divides the traditional cavity, this partition plate serves as a very effective impact and fragmentation receiving plate. After the stone impacts on the partition plate, it is restricted within the small circulation range of a region, which can reduce the energy of mutual impact caused by the long-distance flight of the stone in the cavity. At the same time, within a small range, the stones have more opportunities to collide and squeeze with each other, forming higher production capacity and better particle shape.
[0019] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
