Description
Technical field
The utility model relates to a kind of parts structure-improved of groundnut sheller in agricultural machinery, particularly relates to a kind of structure-improved of extruding peanut hulling machine with hulling drum.
Background technology
Shelling be peanut cultivation, processing and edible before must, through operation, be also the key that affects peanut kernels and product property and commodity simultaneously.The groundnut sheller roll form mostly is and adopts the rotation of rigid material to break rod-type at present.Due to steel and the irony structural rigidity very large, during this kind of version operation, hitting dynamics is large.Linear velocity larger while playing the bar rotation produces large directly the strike and shearing force to peanut pod, though easily make under this strike that the fruit pod is broken, the kernel separation, the easy damaged peanut kernels, percentage of damage and breakage rate are higher, have affected the quality of peanut kernels and goods thereof.Therefore in the urgent need to further improvement improvement behave is arranged, to change the deficiencies in the prior art and drawback.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, intends providing a kind of not easy damaged peanut kernels, the extruding peanut hulling machine hulling drum structure that percentage of damage and breakage rate are lower.
The purpose of this utility model is realized by following technical scheme.
A kind of groundnut sheller hulling drum is characterized in that:
At the soft elastomer rubber roll of the peripheral fixed cylinder shape of middle metal shaft, at the outer wall of rubber roll, four positions that are positioned at quadrature 90 degree are the soft elastomer cuboid raised line bar parallel with axis to outer process respectively;
The radial height h of described raised line bar is 4-6mm;
The central angle β that the circumferential width of described raised line bar is rubber roll is the 30-35 degree;
At rubber roll right-angle view radially, offer the groove tilted with the rubber roll axis on described raised line bar, the raised line bar is by oblique arrangement, wide groove and convex tendon composition, the groove tilted and the angle α of rubber roll axis are the 50-70 degree, the inclined groove opposite direction of offering on adjacent two raised line bars;
Described soft elastomer shore hardness is 70-85.
The hulling machine cylinder is the key factor that affects the hulling machine operation quality, is the core component of groundnut sheller.The utility model adopts soft elastomer rubber roll, and the soft elastomer cuboid raised line bar parallel with axis to outer process at the outer wall of rubber roll offered the groove tilted with the rubber roll axis on the raised line bar.So with respect to the advantage of existing rigid cylinder, for both peanut was had to certain hitting power, the peanut pod of guaranteeing to break, can make again hitting power be controlled to a certain degree to structure, and the hitting power while avoiding operation is excessive, makes the peanut kernels breakage even broken; The inclined groove opposite direction of offering on adjacent two raised line bars, while making operation, peanut pod is subject to the periodically variable active force of direction, and rolling in the increase process, kneading action, be conducive to kernel and separate with the fruit pod.Therefore, this kind of structure can effectively reduce percentage of damage and the breakage rate of peanut kernels when guaranteeing higher threshing performance.
Workpiece physical dimension and material hardness that the utility model limits are also to guarantee to realize the utility model purpose essential condition.
Further, described soft elastomer shore hardness is 75.
Further, described soft elastomer is polyurethane material.
Further, the radial height h of described raised line bar is 5mm; The central angle β that the circumferential width of described raised line bar is rubber roll is 32 degree; The angle α of the groove of described inclination and rubber roll axis is 60 degree; The width L of described raised line bar upper groove and convex tendon is 11.5mm; The diameter of rubber roll is 220mm, and length is 290mm.
Further, described rubber roll is fixedly connected with axle by the injection moulding mode.
By great number tested data, add up, the utility model percentage of damage is starkly lower than prior art.
Advantage of the present utility model and beneficial effect, overcome the drawback of prior art.1. adopted cylindric soft elastomer rubber roll, weakened and controlled certain strike peanut dynamics; 2. the raised line rod-shape structure of the utility model uniqueness, guarantee the hitting power that provides enough; 3. the inclined groove opposite direction of offering on adjacent two raised line bars, further ensure again relative roll, kneading action, effectively reduce percentage of damage and the breakage rate of peanut kernels when guaranteeing higher threshing performance.
