Description

Technical Field

[0001] This utility model relates to the technical field of shell-breaking devices, specifically a sunflower seed shell-breaking device. Background Technology

[0002] In the production of sunflower seeds, shelling devices can be used to remove the shells. According to patent application publication number CN115399484A, a sunflower shelling block and a sunflower shelling device and shelling machine using the block are disclosed. The invention discloses a sunflower shelling block, which includes a rectangular block body. Several parallel guide grooves are formed along the length direction on one surface of the block body. The width of the guide grooves is equivalent to the width of the sunflower seeds. At the corner of the side of the block body with the guide grooves, an inclined surface is cut along its width and length directions. The inclined surface makes the block body gradually thicken from the corner to other corners.

[0003] However, existing shell-breaking devices require a shovel disc to break the shells of sunflower seeds during operation. During this process, the seeds collide with the inner wall of the shell, causing the shells to break and the kernels to be removed. However, the oil in the kernels causes a large amount of seed shell debris to adhere to the inside of the shell and the surface of the shovel disc, clogging the grooves of the shovel disc and affecting the normal use of the shell-breaking device. Therefore, existing technology needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a sunflower seed shell-breaking device that solves the problem that oil can easily cause sunflower seed shell fragments to be adsorbed inside the groove of the splitting block, thus affecting the shell-breaking process.
