Hickory nut is impacted shell after can clamping by two ends and carries out cracking, but in cracking process, has the cuspidated nuts of two ends tool such as problems, particularly pecan tree, easily makes tip stressed when clamping, does not reach good cracking effect.
Summary of the invention
In order to solve the stressed uppity problem of nut shell in nut cracking process, the utility model provide a kind of cracking effective, do not affect nut cracking unit kernel quality, simple to operate.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of nut cracking unit, comprise cracking drill bit, cracking mould, described cracking drill bit, cracking mould are positioned on same level axis, the axial top of described cracking drill bit and cracking mould is provided with draw-in groove, the draw-in groove of described cracking drill bit and cracking mould is in axial direction installed in opposite directions, and the axial end of described cracking mould is provided with percussion mechanism.
Described draw-in groove inner surface is non-linear, described draw-in groove axial cross section comprises a bottom arc-shaped edges, two cracking arc-shaped edges, the center of circle of described bottom arc-shaped edges is on the axial line of cracking mould or cracking drill bit, the center of circle of described two cracking arc-shaped edges is distributed on the both sides in the arc-shaped edges center of circle, bottom, and described bottom arc-shaped edges and two cracking arc-shaped edges are tangent and seamlessly transit.
Further, a kind of nut cracking unit, also be provided with fixed cover, guard ring, pad, described percussion mechanism comprises the first cylinder barrel, mobile piston, described fixed cover one end is fixed on the first cylinder barrel, the described fixed cover other end is provided with concave station, described cracking mould is arranged on by guard ring in the concave station of fixed cover, the axial end of described cracking mould communicates with the inner chamber of the first cylinder barrel, between described guard ring and cracking mould, pad is installed, described cracking mould can minute movement in guard ring, and described mobile piston is arranged in the first cylinder barrel.
Further, a kind of nut cracking unit, is also provided with support, cylinder, described cylinder is made up of the second cylinder barrel, piston, piston rod, and described the second cylinder barrel is rack-mount, and described piston bush is contained in cylinder barrel, described piston connects piston rod, and described piston rod connects the axial end of cracking drill bit.
Further, the radius of described bottom arc-shaped edges is 1/16 of cracking arc-shaped edges radius.
The utility model compared with the existing technology has the following advantages and effect: 1, the axial top of cracking drill bit and cracking mould is provided with draw-in groove, draw-in groove inner surface is non-linear, therefore the nut such as cuspidated pecan tree of tool, while being stuck in draw-in groove, sidewall clamps by two cracking arc surfaces, thereby avoid the most advanced and sophisticated stressed cracking effect that affects, can not cause kernel breakage, improve cracking quality 2, mobile piston slides acting in cylinder of gas, clash into cracking mould, cracking mould has certain mobile space in guard ring, thereby carry out the cracking of nut, cracking is effective, quality is high.3, cracking drill bit can move axially by cylinder control, and aspect clamping, has improved production efficiency.4, simple in structure, cost is low, good in economic efficiency.
