TECHNICAL FIELD

[0001] The utility model relates to the technical field of roll type sand making machine especially a sand making machine roller compaction structure with prismatic pegs. BACKGROUND

[0002] Roll type sand making machine usually includes fixed roller and movable roller, and material is fed from above two rollers, is continuously taken into the roller by extrusion roller, and is discharged from the machine with ideal particle size. The relative movement of two rollers crushes stones into sand. The patent number CN202021220681X of Chinese patent document was granted on April 13, 2021, and the patent number is "a pair of roll type sand making machine", which includes vertical frame, first roller compaction roller, second roller compaction roller and driving motor, the first roller compaction roller and the second roller compaction roller form a roller compaction channel, the first roller compaction roller is rotatably connected to the frame, the driving motor is connected to the frame, the driving motor is used for driving the first roller compaction roller to rotate, the frame is provided with a plurality of supporting legs, the supporting leg includes bottom plate, raised plate, top plate and stand column arranged in sequence from bottom to top, and the bottom plate is provided with a positioning ring. In order to improve the crushing effect, pegs are inlaid on the roller cover (surface layer of roller compaction roller), the inlaying depth of existing pegs is the same, so the roots of pegs are located on the same layer, and the roots of pegs are located on the same layer during use, which is prone to cause the rupture of roller skin. SUMMARY

[0003] The utility model aims at providing a sand making machine roller compaction structure with prismatic pegs, which can prevent the rupture of roller skin.

[0004] The above technical problem is solved by the following technical scheme: a sand making machine roller compaction structure with prismatic pegs, including a roller cover, characterized in that the surface of the roller cover is provided with a plurality of rows of pegs distributed along the circumference of the roller cover, the pegs in the same row are distributed along the axial direction of the roller cover, the pegs are inlaid in the roller cover, and the cross section of the pegs is polygonal; the depths of the pegs in the same row are different, and the pegs in the same row are staggered, which can prevent the roots of the pegs from being located on the same layer (cross section) and causing the roller skin to fall off. Since the roller is circular, the distance between the exposed parts of the pegs is small, and the distance between the roots of the pegs is smaller, so the roots of the pegs are subjected to stress in different depths and staggered, which makes the base layer of the roller skin more durable. The pegs are prismatic, which can improve the crushing effect.

[0005] As a preferred embodiment, the pegs in the two adjacent rows are aligned one by one along the circumference of the roller cover. This can make the pegs more convenient to inlay in the roller cover.

[0006] As preferred, two adjacent studs along the circumference of the roller sleeve are one deep embedded stud and the other shallow embedded stud. The damage of the roller skin can be effectively prevented.

[0007] As preferred, the hardness of the roller sleeve is greater than that of the stud. When the stud is embedded, the stud is deformed by being pressed and embedded with the roller sleeve, so that the deformation of the roller sleeve caused by the replacement of the stud is small, and the deformation is small, so that the roller sleeve can still be used when the stud is replaced many times.

[0008] As preferred, the cross section of the stud is pentagonal or hexagonal. The strength and crushing effect of the stud can be considered.

[0009] As preferred, the studs in the same row are uniformly distributed along the axis of the roller sleeve.

[0010] As preferred, the spacing distance between any two adjacent rows of studs is equal, and the spacing between the axially adjacent studs is equal to the spacing between the circumferentially adjacent studs.

[0011] As preferred, the outer end surface of the stud is a plane. The time of pressing the stone is long, so that the effect of crushing the stone is better when sand is made.

[0012] As preferred, a chamfer surface is provided between the outer end surface of the stud and the side surface of the stud. The stud is not easy to produce curling phenomenon.

[0013] As preferred, the inner end surface of the stud is a spherical surface. The stud is more convenient to embed into the roller sleeve.

[0014] The beneficial effects of the present application are that the depth of the embedded stud is not the same and the interval is staggered, which can effectively avoid the cracking of the roller skin during use. BRIEF DESCRIPTION OF DRAWINGS

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made belong to the protection scope of the present application.

[0020] Referring to Figure 1 and Figure 2 A sand making machine roller structure with prismatic nails comprises a roller sleeve 1. The surface of the roller sleeve is provided with a plurality of rows of nails 2 which are uniformly distributed along the circumference of the roller sleeve. The nails in the same row are uniformly distributed along the axial direction of the roller sleeve. The nails are embedded in the roller sleeve, and the cross section of the nail is a regular hexagon. Adjacent two nails in the same row are embedded in the roller sleeve at different depths, one nail is embedded in the roller sleeve at a greater depth than the other nail, the nail embedded at the greater depth is referred to as a deep embedding nail 3, and the nail embedded at the smaller depth is referred to as a shallow embedding nail 4. The different depths of the embedded nails are staggered, which can prevent the nail root layer from being forced to the same layer (cross section) to cause the roller skin to fall off. Since the roller is circular, the distance between the exposed parts of the nails is small, and the distance to the root is smaller, so the stress of the different depths and staggered nails makes the base layer of the roller skin more durable. The nail is provided in a prismatic shape, and the crushing effect is better.

[0021] The nails in the adjacent two rows are aligned one by one along the circumference of the roller sleeve. Adjacent two nails along the circumference of the roller sleeve are a deep embedding nail and a shallow embedding nail. The hardness of the roller sleeve is greater than the hardness of the nail. The distance between the axially adjacent nails is equal to the distance between the circumferentially adjacent nails. The outer end surface 5 of the nail is a plane. A chamfer surface 6 is provided between the outer end surface of the nail and the side surface of the nail. The inner end surface 7 of the nail is a spherical surface.

[0022] In another embodiment, the rest is the same as this embodiment, but the nail is a regular pentagonal prism.
