A kind of automatic stoning machine for reddates
Technical field
The invention belongs to the agricultrue sideline production processing machinery equipment technical field, relate to a kind of automatic stoning machine for reddates.
Background technology
Red date deep processing development in recent years is very rapid, and extracting red date stone is an important ring in the processing, but processing method is comparatively backward at present, most of still manual row's jujube pin is stepped on the stamping knife stoning, and labour intensity is big, and production efficiency is low, do not meet the food hygiene requirement simultaneously, also exist potential safety hazard.Existing some mechanical stoning processing methods of bibliographical information, as disclosing the pitting method of olive in the U.S. Pat 4220080, patent adopts linked transmission to realize the feeding of olive, utilizes cam to drive stoning pole pair olive and carries out the rigid shock stoning.Because half-dried red date and olive fruit volume property are xylocarp with very big difference, olive are arranged, half-dried red date matter is soft, and this technology can't directly apply to half-dried extracting red date stone; Chinese patent 01229251.6 has proposed a kind of semi-automatic extracting red date stone peeler, adopts the feeding of artificial row's jujube, and connecting rod drives intermittently rigid shock stoning, and the food hygiene situation is not improved, and production efficiency does not significantly improve yet; Chinese patent 200420015662.8 has proposed a kind of automatic red date process equipment, adopts the stepping mechanism feeding, and connecting rod drives and back and forth impacts stoning; Above-mentioned pitting method is applicable to the hard jujube stoning of making candied date, hard jujube and half-dried red date are widely different, so these technology can't be directly used in half-dried extracting red date stone, and owing to adopt the rigid shock stoning, be difficult to guarantee the success rate of stoning, the easy damage that produces waste product and cause parts, and the said equipment complex structure, the manufacturing cost height.
